2939 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2941 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2942 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2944 One basic decision: e.g. src/clean.mk includes further files. In order
2945 to make this work there are two solutions:
2946 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2947 run configure on them. This way they can use
2948 'include $(srcdir)/port-clean.mk'
2949 - always include clean.mk by the Makefile at the same level. To avoid
2950 that `make clean` tries to include and build Makefile.dep the
2951 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2952 implemented, because now even `make uninstall` doesn't create
2953 Makefile.in. clean.mk could be eliminated by pasting it in
2956 * debugger/mcs51/Makefile.in: build own objects from library sources
2957 (SLIB, SDCC) in current directory
2959 * configure, configure.in: renamed --disable-device-lib-build in
2960 --disable-device-lib; added --enable-doc, the required tools are
2961 searched by configure; added result message; the toolchain for the
2962 belonging ports are now only built, if the port is enabled.
2964 * support/regression/*: all output is written in directory gen, because
2965 the fwk and ports directories don't livet in the build tree using vpath
2967 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2968 --disable-device-lib, added --enable-doc, added section VPATH
2970 * sim/ucsim/configure.in,
2971 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2972 z80 are enabled by default
2974 2006-04-24 Raphael Neider <rneider AT web.de>
2976 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2977 to config word, "pic14_"-prefixed some extern functions
2978 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2979 config word has been found
2980 * src/pic/device.h: added prototypes
2981 * src/pic/pcode.c: added "pic14_"-prefix where needed
2982 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2984 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2986 (pic14emitRegularMap): ignore config words,
2987 (pic14createInterruptVect): moved generating __config directives away
2988 (picglue): have __config directives emitted
2990 2006-04-24 Borut Razem <borut.razem AT siol.net>
2992 * doc/Makefile: sync with nightly build makefile
2994 2006-04-24 Raphael Neider <rneider AT web.de>
2996 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2997 registers that have not been assigned proper liveranges,
2998 fixes #1469504 and #1474602,
2999 (pCodeRegOptimizeRegUsage): fixed typo in comment
3001 2006-04-24 Borut Razem <borut.razem AT siol.net>
3003 * device/examples/main8051.c: deleted - it was removed from CVS
3004 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3005 after the transition to Subversion
3006 * src/SDCCalloc.h: deleted - it was removed from CVS
3007 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3008 after the transition to Subversion

3245 implemented patch 1120823 Thanks to Willy De la Court (normal
3246 interrupts need an interrupt number now if they are made critical),
3247 and enabled nesting of critical functions though not for gbz80
3248 (genCritical, genEndCritical): added functions
3249 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3250 * src/z80/mappings.i: added "ei" to all mappings

3262 the left operand is shorter than the result (c* = lit-c* + int),
3264 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3267 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3269 * src/.version: increased version number to 2.5.5
3270 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3271 linking is done manually in pic16 port's _linkEdit,
3272 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3273 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3274 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3275 allocate asmop as AOP_ACC,
3276 (aopForRemat): added parameter 'bool result' in function declaration,
3277 (pic16_aopGet): return AOP_ACC when accessing WREG,
3278 (pic16_popGetTempReg): minor modification,

3289 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3290 call to allocReg, not by manually allocating a new one,
3291 (pic16_assignRegisters): now before going through the register
3292 allocating functions mark all registers as free. This eliminates some
3293 side effects resulting from peephole parser done earlier in the backbone
3295 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3353 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3354 which dumps before the function entry point a data byte which represents
3355 the number of the local variables used by the specified function, added
3356 'xinst' for initial support for Extended Instruction Support,
3357 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3358 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3359 port->fun_prefix anymore (may change later),
3360 (genFunction, genEndFunction): do not store/restore local registers for
3361 _main (this should take care the --main-return command line option in
3363 (genOr): removed some legacy pic-port instructions,
3364 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3365 performing operations with SFR's causes data to be written more than
3366 once to each SFR. Perhaps SFRs should be handled in special cases...
3367 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3369 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3370 into account for stack starting position,

3372 --extended or -y for Extended Instruction Support,
3373 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3374 (deassignLRs): *** perhaps the most important change, old 'for' code
3375 (commented out for reference), didn't account for some registers which
3376 were left marked 'not free' after a pointer operation. The change
3377 reduces register usage a lot in some cases
3379 2006-03-04 Borut Razem <borut.razem AT siol.net>

5654 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5655 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5656 always available in leading double underscore form. The C99 support is
5657 mostly missing, but it's a start.
5658 * support/regression/tests/bug-227710.c: fixed nonconforming use of

5739 * device/lib/printf_large.c: removed inline assembly for portability and
5740 readability. Use printf_fast if speed or size are more important.
5741 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5742 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5744 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5746 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5747 prevent compiler warning
5749 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5751 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5752 moved to level 0 and declared as static. Also they are explicit
5753 placed in access bank. This was necessery because some times they
5754 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5755 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5756 optimizations. Currently only compare to unsigned char is implemented,
5757 * src/pic16/gen.c: added fReturnIdx array,
5758 * (struct resolvedIfx) is moved to gen.h and made public,
5759 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5760 * (aopForSym): added an optimization to directly store in stack of
5761 the operand of a SEND iCode,
5762 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5763 but as registers instead (AOP_REG) using the fReturnIdx array,
5764 * (pic16_freeAsmop): remove the freed register from the
5765 _G.sregsAlloc field,
5766 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5767 a compare of 'WREG',
5768 * (pic16_popGetTempRegCond): changed function prototype, now
5769 function takes also a bitVector argument v which holds the current
5770 set of registers that are allocated for stack access by aopForSym,
5771 registers allocated in aopForSym for accessing stack symbols are not
5772 any more part of the functions usedRegs field,
5773 * (genCall): some times aopOp is called for a stack variable to be
5774 send, aopForSym might perform the push, if this is true make sure
5775 that genCall doesn't push the variable twice by testing _G.resDirect,
5776 * (genFunction): changed testing for unspecified interrupt number
5777 from 256 to INTNO_UNSPEC,
5778 * modified selection scheme of frame pointer generation. Previously
5779 if function did use local registers a frame pointer was generated,
5780 now a frame pointer is generated only if function has arguments
5781 (that need PLUSW2 register access), or has stack arguments, or the
5782 compiler is not instructed to omit the frame pointer,
5783 * (genEndFunction): before restoring local registers that were saved
5784 in the function preamble, also restore the registers that *might*
5785 have been allocated for stack access,
5786 * (genRet): removed some old comments,
5787 * (genCmp, the active (RN's) version): added a call to the
5788 pic16_genCmp_special function to perform the compare with a more
5789 robust and optimized way,
5790 * (genInline): a feature has been added in inline code generation,
5791 which allows a wildcard variable substitution when writing inline
5792 assembly. Code is incomplete and experimental therefore undocumented,
5793 * (genCast): changed order of aopOp for result and right to allow
5794 aopForSym to directly load the result if possible,
5795 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5796 perform an optimized compare on some selected special occasions,
5797 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5798 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5799 generate an IVT any more,
5800 * src/pic16/main.c (pic16_optionsTable): added command line option
5802 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5803 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5805 * src/pic16/NOTES: Raphael Neider added in list of active developers
5806 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5807 jumptable_end to prevent bug #,
5808 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5809 inCond and outCond fields,
5810 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5811 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5812 turn off register spilling,
5813 * (packRegsForOneUse): synced with other ports' versions although it
5814 is not used currently,
5815 * (pic16_packRegisters): added an optimization while reading
5816 structure bitfields, some registers may be saved (malloc code is
5817 decreased by 80 bytes)
5819 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5821 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5822 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5823 this can be optimized more?
5825 2005-03-10 Raphael Neider <rneider AT web.de>
5827 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5828 genNearPointerGet): (hopefully) fixed access to bitfields via
5829 pointers (p->bitN = x; and x = p->bitN; failed)
5831 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6461 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6463 Adding support for replacing ljmps with sjmps in jumptables
6464 generated for switch statements. For now you need to set the
6465 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6466 Now 4 algorithms for mcs51 jumptable generation are used:
6467 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6468 addresses loaded pc-relative for up to 112 cases and stack-pushing
6469 target addresses loaded with offset from dptr for up to 256 cases.
6471 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6472 * src/mcs51/main.c: adapted constants for switch table generation

6496 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6497 to call when a stack overflow occurs,
6498 * (malloc.h): added CVS Id tag,
6499 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6501 * added libc directory. The current version of LibC contains string
6502 functions, ctype functions and macros and some functions of the
6503 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6504 be extensively tested in the future. Standard disclaimer here.
6505 Library is not automatically build yet. But one can build it by
6506 invoking 'make' inside the libc directory.
6507 * added ADC library under libio. Preliminary version yet.
6509 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6513 temporary registers, its a buggy feature and will be removed,
6514 * (pic16_popGet): set register instance field in AOP_CRY,
6515 * (pic16_outBitC): fixed for results in size greater than 1,
6516 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6517 * (pic16_storeForReturn): optimized return of 0,
6518 * (genCmp): experimental code for new genCmp which uses PIC18's
6519 special compare&skip instructions. Initial tests fail some times
6520 with variables grater than 1 byte in size, so new code is disabled,
6521 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6523 * (genCast): began a fix to optimize the casting of a bit to another
6524 bit, now assigning a bitfield to another bitfield will fail, sorry,
6525 * src/pic16/main.c: disabled the use of lr-support feature,
6526 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6527 * added some function prototypes, added function _debugf prototype,

6529 bits with offset (case PO_GPR_BIT),
6530 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6532 * (isBankInstruction): modified to return 0 for no banking instruction,
6533 and 1 for banking instruction,
6534 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6535 caused stop processing pCodes after a inline assembly block,
6536 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6537 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6538 registers when it shouldn't,
6539 * src/pic16/ralloc.c (allocReg): add preliminary support for
6540 supporting a limited set of temporary registers,
6542 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6544 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6545 genDataPointerSet): ensure assignments always copy in MSB to LSB
6547 (loadRegFromAop): recognize CLRH optimization,
6548 (genFunction): optimize RECEIVE iCodes in reentrant functions
6550 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6552 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9524 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY
9525 (genMultOneByte): fixed bug in signed vs unsigned multiplication
9526 * sim/ucsim/hc08.src/inst.cc (inst_clr): added missing effective
9527 address fetch for clr instruction

9547 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9549 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9550 loaded with the linker search paths (-L arguments) and the libraries
9551 to be linked with the current source (-l arguments). Changes
9552 currently will affect only the pic16 port.
9553 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9554 include path the port specific paths and port specific libraries,
9555 * gplink command now contains the $3 argument,
9556 * src/pic16/device.h,
9557 * src/pic16/device.c,: structure PIC_device is made public and
9558 renamed to PIC16_device, the same for variable Pics which is renamed
9559 to Pics16. Updated all references to them.
9560 * src/pic16/glue.c (pic16glue): corrected bug with code
9561 initialization which bypassed the variable initializations block.
9563 * device/lib/pic16/Makefile.rules: removed --penable-stack from

9571 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9573 Documenting changes from previous commits.
9574 * configure.in (version 1.56),
9575 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9576 when generating output files to configure the pic16 library,
9577 but now I've commented it out, since gputils aren't installed in the
9578 SF compile farm, so library won't compile
9580 * device/lib/Makefile.in (version 1.56): initially I've added in
9581 target 'all' the prerequestive 'model-pic16' so it compiled the
9582 pic16 library, but now I've commented it out for the same reasons
9584 * added targets 'model-pic16' and 'objects-pic16' to compile the
9586 * added target 'port-specific-objects-pic16' to handle the
9587 generated libraries and copy them into the build/ directory
9588 * added target 'clean-intermediate-pic16' to clean intermediate
9589 files into pic16 directory
9590 * in target 'installdirs' added line to create directory pic16 in
9591 the installation path
9593 * device/include/Makefile.in (version 1.11): in target 'install'
9594 added lines to copy all header files to installation path,
9595 * in target 'installdirs' added line create directory for pic16
9596 headers in the installation path

9611 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9612 option so that it actually works. Made it specific to the z80, since
9613 the gbz80 doesn't have these kinds of I/O ports.
9615 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9617 * device/include/z180.h,

9630 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9632 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9633 changed interrupt vector table generation to only emit declared vectors.
9634 * device/include/Makefile.in: added missing backslash
9635 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9639 Mainly changes to support compilation of the device libraries
9640 * src/pic16/device.c: stack is allocated via symbol and not
9641 via literal number. The symbol is placed in the corresponding
9642 position of the data ram
9643 * (pic16_dump_section): relocatable and absolute uninitialized
9644 data are now emitted in sorted order to reduce section naming,
9645 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9646 weren't marked as being in the access bank,
9648 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9650 Added portion of GNU PIC Library under the directory
9651 device/include/pic16 and device/lib/pic16. These files
9652 contain the declarations of SFRs for the PIC18Fxx2 devices.
9653 The directory is initialized via configure from toplevel.
9655 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9657 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9658 the spilllocations to be compared correctly
9660 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9662 * src/SDCCast.c (decorateType): fixed bug introduced today
9664 2004-01-12 Borut Razem <borut.razem AT siol.net>
9666 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

9682 * doc/sdccman.lyx: Moved and added some sections, small changes
9683 all over. Telling LaTeX to be less strict with word spacing
9684 to better keep the right margin. Changed some notes about
9685 maintainance of the ports in section 3.2.1 - is it OK like this?
9687 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9689 SDCC source changes:
9690 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9723 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
9724 UPPER for immediate operands,
9725 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9727 * src/pic16/peeph.def: all peepholes with movff are commented out,
9728 because there is a problem in the pcode peep optimizer,
9729 * src/pic16/ralloc.c: the register allocator can now reuse local
9730 function symbols for another function. This saves register usage.
9731 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9733 Added file src/pic16/NOTES with information about program writing on
9734 the current port version.

9743 * src/SDCCmain.c : fixed #872250: -l command line defined library
9744 files are scanned before standard library files
9746 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9763 gen51Code): more efficient parameter receive for --model-large
9766 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9769 * src/z80/main.c: added missed needLinkerScript flags (more than
9770 one port structure defined in these file)
9771 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
9774 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

9787 needLinkerScript flag
9789 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9790 * src/pic/glue.c: added variable udata_section_name to
9791 override default uninitialized data segment definition for
9792 devices only with SHAREBANK memory (reported from Erik Epetrich)
9793 * (pic14emitOverlay): modified to emit a commented overlay segment
9794 directive when no overlay data exist
9795 * (picglue): modified to emit uninitialized data segment
9796 according to udata_section_name
9797 * src/pic/main.c (_pic14_parseOptions): added command line

9801 arguments via -W option
9802 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9803 object file from '.rel' to '.o' in port->linker structure,
9804 changed size of fptr from 2 to 3 in port structure
9806 2004-01-07 Borut Razem <borut.razem AT siol.net>
9808 * support/scripts/sdcc.nsi: update PATH
9809 * support/scripts/sdcc.ico: craeted
9811 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9813 * device/include/Makefile.in: fix install
9814 * doc/Makefile: fix install
9816 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9818 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
9820 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
9821 how the function variable allocation summary is displayed; also
9822 include information about variables allocated to the overlay
9825 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9827 * as/mcs51/lkmain.c: Help about -Y option

9836 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9837 LEFT_OP (left shift)
9839 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9841 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9842 (default behaviour).
9844 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9846 A python script to validate compiler diagnostic messages. It can be
9847 used to verify that sdcc complains about bad c source code and
9848 gives a good location of the error.
9849 * support/valdiag/Makefile,
9850 * support/valdiag/valdiag.py,
9851 * support/valdiag/tests/*
9853 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9855 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9856 * src/SDCCsymt.c (newEnumType),
9858 * support/Util/SDCCerr.c,
9859 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9861 * support/regression/tests/enum.c: added test for enum values that

9864 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9866 * src/common.h: added ifndef/define/endif macros
9867 around the header file.
9868 Bug reported from Jesus Calvino-Fraga
9870 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9872 * sdcc.spec: updated
9873 * device/include/Makefile.in: don't install CVS directories
9874 * device/lib/Makefile.in: added removal of CVS directories after install
9875 * doc/Makefile: fixed install, added local_icons
9876 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9877 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9878 * src/ds390/gen.c (genRightShift): fixed bug #870788
9879 * src/SDCCast.c (decorateType): fixed bug #870781
9881 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9883 PIC16 port related changes:
9884 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9885 added variable stackPos,
9887 * gen.c: genCall, assignResultValue: added support for
9888 pushing/retrieving function parameters to/from stack,
9889 genFunction,genEndFunction: setup stack frame for the
9891 genAddrOf: will be changed according to bug 863624
9893 * added files genutils.c and genutils.h which contain gen*
9894 debugged and optimised functions extracted from gen.c
9896 * glue.c: added variable 'externs' which holds extern symbols,
9897 pic16emitRegularMap: is modified to properly handle relocatable
9898 symbols under the new scheme,
9899 pic16createInterruptVect: is modified
9900 pic16printPublics: is modified to emit 'global' assembler directives,
9901 added pic16_printExterns to print extern symbols,
9902 pic16glue: initializes stack/frame pointer in the beginning of
9903 the assembly output. Temporary hack, will be corrected later,
9904 because gplink yet does not support stack and SDCC does not
9905 yet support a type of crt0.o object to create the final binary.
9907 * Removed many lines that contain 8051 legacy code.
9908 * The code is finally placed under a 'code' directive.
9909 * Added port specific options.
9911 * _process_pragma: simplified since now we do not need *special*
9912 include file to define SFR registers. But a separate header
9913 will be needed. This will be developed later.
9914 * _pic16_parseOptions: added, parses port specific options:
9915 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9916 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9917 --preplace-udata-with=
9919 * _pic16_setDefaultOptions: modified to initialize section names,
9920 but hack is temporarly out of order since it needs improvement.
9921 * _pic16_genAssemblerPreamble: configuration words are emitted by
9922 their address instead of their name. This part is incomplete and
9923 supports only the 18Fxx2 devices. Other devices will emit an error
9924 during assembly since they do not contain the same set of config
9926 * _pic16_genIVT: is modified,
9928 * pcode.c: added definitions for some hardware registers that are needed
9930 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9931 All PCI entries are updated. Now LFSR is supported.
9932 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9933 * added pic16_newpCodeOpLit2 to support instructions with
9934 two literal arguments
9935 * pic16_pCode2str: corrected code that emits assembler instructions
9936 with two literal operands and those that have an access bit modifier
9937 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9938 this fixes a bug which caused some labels to be lost, when an
9939 assembler directive was added, i.e. banksel,
9940 * pic16_FixRegisterBanking: improved logic that causes the insertion
9942 * InlineFunction: functions that are called once, are not any more
9943 inlined. This can be a port option in the future,
9945 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9947 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9948 hold the corresponding uninitialized symbols,
9949 * pic16_allocProcessorRegister: registers have explicit marked the
9951 * pic16_allocInternalRegister: registers are explicit marked as
9953 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9954 processing list, so bit registers were lost,
9957 * ralloc.h: added field 'accessBank' and original symbol operand
9958 in register definition,
9959 * removed the field isMapped from register definition,
9961 ** Several functions have been removed from various sources:
9962 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9963 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9964 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9965 pic16_assignRelocatableRegisters
9967 ** others have been introduced:
9968 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9969 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9971 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9973 * support/scripts/inc2h.pl: changed definition of BIT_AT
9974 to emit 'sbit at' instead of 'bit at'. This was a request.
9976 PIC16 port related preliminary changes:
9977 * gen.c: prefixed function popRegFromString with
9978 pic16_ and all references to it corrected
9979 * pcode.c: all pic16_pc_* hardware registers prefixed
9980 with underscore (_),
9981 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9982 * ralloc.c: newReg(): when register is REG_SFR then
9983 set address to rIdx,
9984 pic16_allocProcessorRegister(): marks register wasUsed=0
9985 pic16_writeUsedRegs(): added a call to assign processor
9986 registers via pic16_assignFixedRegisters
9988 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9990 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9991 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9992 variables in unused register banks. Also the SSEG is placed
9993 wherever there is enough space for it, and IDATA can be anywhere
9994 in internal RAM. For now compile using -Wl-Y[stack_size].
9995 The mem file is different for this option as well, since it
9996 makes no sense of talking about DSEG lenght.
9998 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10000 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10001 in certain cases, e.g. when ROM assignment, patch provided
10002 from Albert den Haan.
10004 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
10006 Many signedness and type propagation fixes:

10980 pcoderegs.h, ralloc.c, ralloc.h
10981 * main.c: added top header and GPL license notice
10982 * pcode.c: fixed the if-conditional warning
10984 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10986 * device/lib/_mullong.c: replaced int by short for gcc
10988 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10990 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10991 and JUMPTABLE iCodes properly now (worked by accident before)
10992 * src/mcs51/gen.c (leftRightUseAcc),
10993 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10994 iCode properly now. Use getSize instead of nRegs since a & b
10995 aren't part of the nRegs tally.
10997 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10999 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11008 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11009 copied from genNearPointerSet()
11010 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11011 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11012 If they pop r0/r1 they must be called in the opposite order than aopOp().
11013 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11014 (resp. --stack-auto), prepared for --xstack
11016 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11018 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11020 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11022 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
11023 these ports have their own __sdcc_external_start()
11025 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11027 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11028 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11029 type for bits was changed. It resulted in bit variables becoming
11030 global, which is not permitted in PIC 14 assembly output.
11032 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11034 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11036 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11038 Z80 and MCS51 linkers complaint if a public symbol is defined
11039 in more than one library module:
11043 * as/mcs51/Makefile.in
11045 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11047 A few small changes that speed up the peephole optimizer.
11051 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11053 Try to make the peephole optimizer smarter by maintaining
11054 an association between the assembly source code and the
11055 iCodes that originated them. Put this information to use
11056 with a new peephole rule condition "notVolatile" so that
11057 the rules can be aggressive yet still safe.
11062 * src/mcs51/peeph.def
11064 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11068 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11069 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11070 if the left or right operand symbols have the accuse flag set.
11072 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11074 Changed the type of the result of the ! (NOT) operator to char;
11075 previously it returned the same type as the source. This allows
11076 us to eliminate all the genFloatNot functions (all of its target
11077 implementations were very buggy) since !float can use the same
11080 * src/SDCCicode.c (ast2iCode): ! returns char
11081 * src/mcs51/gen.c (genNot, genNotFloat),
11082 * src/ds390/gen.c (genNot, genNotFloat),
11083 * src/z80/gen.c (genNot, genNotFloat),
11084 * src/pic/gen.c (genNot, genNotFloat),
11085 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11087 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11089 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11090 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11091 during interrupts. Ensure WSAVE is located at a shared bank address.
11092 2. Fixed page selection in some places
11093 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11094 the registers name strings.
11095 4. Fixed "signed / unsigned compare" compiler warnings.
11096 5. The PIC port manages its own allocation of the general purpose
11097 registers, but makes no attempt to reuse them. As a result when
11098 compiling it soon runs out of general purpose registers. Some
11099 additional code was added to the files pcode.c and device.c to walk
11100 through the function call tree and rename the registers so that they
11110 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11111 genPlus() & genMinus() when the result is the same as left or right
11113 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11117 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11119 Made bitfield a distinct type from bit so that bitfields
11120 convert as per ANSI C and bits retain their traditional
11121 boolean style behaviour. Implemented bitfield support in
11129 * src/ds390/gen.c: bit v bitfield split
11130 * src/z80/gen.c: New support for bitfields
11131 * support/regression/tests/bitfields.c: reenabled z80,
11134 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11136 Rules 246.x, 247.x relate to bitfields, the others speed up
11137 access to xdata mapped I/O devices.
11139 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11141 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11143 Cleaned up genPackBits and genUnpackBits and added two helper
11144 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11145 for literal assignments in genPackBits (thanks to Frieder for
11151 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11153 Fixed bug #748310 (pointer to function type mishandled when the
11154 function name is omitted). Also fixed a SIGSEGV when a function
11155 attribute (reentrant, etc) is used on a non-function or on a
11156 function but misplaced before the parameter list.
11158 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11160 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11161 * support/Util/SDCCerr.h,
11162 * support/Util/SDCCerr.c: Added func attr misuse error msg
11164 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11166 Fixed bug #787649 by anonymous
11167 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11168 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11170 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11172 Fixed numerous bitfield problems.

11183 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11185 Made the constant following the "interrupt" keyword optional. If
11186 omitted, the function will not automatically be given an entry
11187 in the interrupt vector table (similar to #pragma NOIV, but
11188 less syntacticly kludgy). The interrupt number is also now
11189 range checked. Also fixed a bug in the high order bit example
11196 * support/Util/SDCCerr.c
11197 * support/Util/SDCCerr.h
11200 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11204 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11205 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11207 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11208 be re-activated by defining REDUCE_LITERALS)
11209 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11210 unsigned, but are signed by default
11211 * src/SDCCval.c (constVal): rearranged
11212 * src/SDCCval.c (valMod): preliminary fix
11213 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11253 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11254 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11255 constants are unsigned; added recognition of "u" flag for unsigned
11256 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11257 * src/SDCCval.c (valDiv, valMod): fixed signdness

11665 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11666 the regression tests I'm not brave enough to enable 245.b, 245.c
11667 * doc/sdccman.lyx: added latex preamble for hyperref package.
11668 Using pdflatex this will give you a hyperlinked pdf file with

11719 added if/endif conditional macros to remove options help
11720 messages from optionsTable when a port is not configured, added
11721 support for the PIc16 port in the ports table, when executing
11722 the compiler with no port specified on command line, a default
11723 port is selected with the new macro DEFAULT_PORT which is
11724 defined in port.h, in setDefaultOptions() linkOptions is removed
11725 from initialization assignment, since now it is a set,
11726 parseCmdLine uses setParseWithComma for linkOptions, in
11727 linkEdit() linkOptions are accessed with new function indexSet()
11728 which returns the i'th item of a set variable. See SDCCset.c, in
11729 linkEdit() when calling buildCmdLine(), added linkOptions as
11730 last argument. Now users can pass arguments to gplink via the
11731 -Wl option, main() uses pic16glue() to glue up pic16 programs

11743 * src/pic16/glue.c: commented out some error producing lines
11744 * src/pic16/main.c: __config directives are commented out to stop
11745 gpasm complaining and test the linkage with gplink, _linkCmd and
11746 _asmCmd changed to be more gplink and gpasm friendly
11747 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11748 produced an error when parsed, peep rule 12 is added to utilize
11749 movff, but it is commented out since the pCode does not support
11750 yet a command with 2 address arguments
11752 2003-05-18 <johan AT balder>
11754 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12789 * src/SDCCicode.c: fixed array add
12791 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12792 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12793 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12795 2003-01-04 <johan AT balder>
12797 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12799 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12800 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12802 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12803 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12804 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12806 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12807 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12809 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12810 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12812 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12813 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12815 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12817 * in /sdcc/as/mcs51/ changed these files in order to create an
12818 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12819 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12820 following files to include the previous two files: aslink.dsp,
12821 Makefile.aslink, Makefile.bcc, and Makefile.in.
12823 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12824 .adb instead of .cdb
12826 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12828 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12829 value from option --iram-size.
12831 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12833 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12836 2002-09-18 <wiml AT hhhh.org>
12838 * SDCClrange.h: exposed setFromRange() and setToRange()
12839 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12840 packRegsForAccUse() (bug 542397)
12841 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12842 multiple times and emitting the fetch operations more than once
12843 added aopGetUsesAcc() function to allow binary operators to
12844 fetch their operands in the correct order; made genMinus() emit
12845 compact code for X = LITERAL - Y
12847 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12848 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12849 sprintf() in line 1267.
12851 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12852 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12855 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12856 Changes to aslink (All the changes are marked with 'JCF'):
12858 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12861 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12862 area BSEG. Also moves, if possible, the DATA area down into the internal
12863 ram so more space is available.
12865 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12868 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12869 not bytes. Function summary() which creates a memory usage summary
12870 file with extension .mem. Reports of overlaping stack and small stack
12871 size. If the space for the stack is less than 16 bytes aslink trows a
12874 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12875 the 8051. Option 'y' for memory summary output file.
12877 Changes to sdcc (All the changes are marked with 'JCF'):
12879 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12881 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12882 overlaying area for it (uses RegBankUsed[4]).
12884 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12885 bank zero as used by default. By default aslink locates the stack
12886 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12887 the creation of the .mem file. Delegates the allocation of data area
12888 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12889 the begining of the stack area to aslink.
12891 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12892 glue() in SDCCglue.c creates an area for it.
12894 2002-09-03 Borut Razem <borut.razem AT siol.net>
12895 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12896 sdcc/src/pic/glue.c:
12897 introduced atexit() handler for teporay files removal in case of
12898 errors, assertions, ...
12900 2002-08-29 Borut Razem <borut.razem AT siol.net>
12901 * sdcc/support/cpp2/auto-host_vc_in.h:
12902 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12903 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12904 Maybe there is a similar problem with BORLANDC? It should be checked!
12906 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12907 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12908 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12909 was not executed, and the compiler (cl) launched a warning:
12910 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12912 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12913 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12915 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12916 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12918 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12919 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12920 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12921 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12922 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12923 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12924 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12925 - added Release configuration in VS projects
12926 - review of compiler an linker options
12927 - VC .exe files are generated in bin_vc directory, not to interfere
12928 with binaries generated from other projects (cygwin, mingw, bcc ...)
12930 * sdcc/src/yacc.dsp: added
12932 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12933 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12934 and insert the version number definitions from .version
12936 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12938 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12939 added - genarate auto-host.h using auto-host_vc_in.h as template
12942 removed from CVS, generated automatically
12944 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12945 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12947 2002-08-11 Borut Razem <borut.razem AT siol.net>
12948 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12950 2002-08-10 Borut Razem <borut.razem AT siol.net>
12951 * src/SDCCmain.c (main):
12952 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12953 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12954 The consequence was that some temporary files were not removed.
12957 unification of code in functions tempfilename() and tempfile():
12958 function tempnam() is defined in Visual Studio 6.0 and .NET
12960 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12962 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12963 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12964 - removed compiler command line option /WX: Treats all warnings as errors
12965 - update a list of source files, included into the project
12967 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12968 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12969 changed project type to Generic Project so that can be correcly converted to VS.NET project
12971 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12973 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12975 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12977 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12978 added return 0 statements after assert() to make compiler happy
12980 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12981 added newline in the def file to keep MSC compiler satisfied
12983 * sdcc/src/z80/gen.c:
12984 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12985 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12986 - solved MSC error in function aopDump()
12988 * sdcc_vc.h: define PREFIX as "\\sdcc"
12990 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12991 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12994 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12995 - Rewrote the register banking algorithm.
12996 - Added pCode live-range analysis to registers (for now, only non-used and
12997 singly-used registers optimized away)
12999 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13001 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

13026 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13028 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13030 2002-03-28 Johan Knol <johan AT balder>
13032 * src/SDCCval.c: fixed bug #532436
13034 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13036 Added "char *Processor" field to the port structure.
13039 Added -p option. Allows port dependent processor to be specified.
13042 Initialized the new field char *Processor field to NULL in all ports
13045 Compiler generated registers for interrupt context saving
13046 were not getting allocated.
13048 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13051 Fixed left shift. Will promote the left side of a left shift
13052 if a) left shifting more than size of operand or b) when assigned
13053 to something size > size of left side
13055 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13057 tons of changes. Register allocation has been
13058 rewritten. Added customization for the various PICs. Flow
13059 analysis is restructured. ...
13061 * src/pic/device.h:
13064 * src/pic/device.c:
13065 Added. device.c is a PIC port hack to accomodate variations
13068 2002-03-13 Michael Hope <michaelh AT vroom>
13070 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13072 2002-03-04 johanknol <johanknol AT manik>
13074 * /src/SDCCval.c: fixed
13076 const unsigned char arr[][2] = { { 0, 1 } };

13163 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13165 * sdcc/src/SDCCloop.c:
13166 Previous fix was not good. basic blocks that have "break" or "return" are
13167 not really partof a loop , but live ranges used in these blocks should
13168 be live thru the entire loop, so set partOfLoop but don't add them to
13171 2002-02-21 <johan AT FRIJA>
13173 * src/SDCCcse.c: fixed bug #514308
13175 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13178 Fixed BUG #519583. If a conditional block ended in a return/break
13179 statement inside a loop, it was not being considered part of the loop.
13181 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13183 2002-02-10 Karl Bongers <karl AT turbobit.com>

13192 * device/examples/Makefile, examples/test3.c:
13193 Add Makefile in device/examples folder, compiles test3.c
13194 for use as a multiple module SDCDB test case.
13196 * sim/ucsim/cmd.src/cmdset.cc:
13197 Took out debug printfs in ucsim "next" command.
13199 * sim/ucsim/xa.src:
13200 Karl and Johan start ucsim XA support. Most dissassembly working,
13201 about 75% emulation done(plenty of work remaining).
13203 * sim/ucsim/z80.src:
13204 Add Z80 support to ucsim, add test-ucz80 regression test,
13205 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13206 Notice z80 compiler fails on examples/test3.c/crc code.
13208 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

13222 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13223 1) handle multiple send & receives from register bank1
13224 2) ralloc can now allocate DPTR1 to some liveRanges
13226 * src/SDCCsymt.c, src/SDCCsymt.h:
13227 changes to handle multiple sends & receives
13229 * src/SDCCptropt.h:
13230 added some pointer arithmetic optimization
13232 * src/SDCCptropt.c:

13234 called from anywhere (will get this working shortly)
13236 * src/SDCCopt.c: fixed for multiple sends & receives
13239 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
13240 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
13241 set preprocessor defines (depending on options)
13243 * src/SDCCicode.c, src/SDCCicode.h:
13244 changes made to handle multiple sends & receives
13247 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
