2903 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2905 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2906 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2908 One basic decision: e.g. src/clean.mk includes further files. In order
2909 to make this work there are two solutions:
2910 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2911 run configure on them. This way they can use
2912 'include $(srcdir)/port-clean.mk'
2913 - always include clean.mk by the Makefile at the same level. To avoid
2914 that `make clean` tries to include and build Makefile.dep the
2915 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2916 implemented, because now even `make uninstall` doesn't create
2917 Makefile.in. clean.mk could be eliminated by pasting it in
2920 * debugger/mcs51/Makefile.in: build own objects from library sources
2921 (SLIB, SDCC) in current directory
2923 * configure, configure.in: renamed --disable-device-lib-build in
2924 --disable-device-lib; added --enable-doc, the required tools are
2925 searched by configure; added result message; the toolchain for the
2926 belonging ports are now only built, if the port is enabled.
2928 * support/regression/*: all output is written in directory gen, because
2929 the fwk and ports directories don't livet in the build tree using vpath
2931 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2932 --disable-device-lib, added --enable-doc, added section VPATH
2934 * sim/ucsim/configure.in,
2935 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2936 z80 are enabled by default
2938 2006-04-24 Raphael Neider <rneider AT web.de>
2940 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2941 to config word, "pic14_"-prefixed some extern functions
2942 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2943 config word has been found
2944 * src/pic/device.h: added prototypes
2945 * src/pic/pcode.c: added "pic14_"-prefix where needed
2946 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2948 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2951 (pic14createInterruptVect): moved generating __config directives away

2962 fixes #1469504 and #1474602,
2963 (pCodeRegOptimizeRegUsage): fixed typo in comment
2965 2006-04-24 Borut Razem <borut.razem AT siol.net>
2967 * device/examples/main8051.c: deleted - it was removed from CVS
2968 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2969 after the transition to Subversion
2970 * src/SDCCalloc.h: deleted - it was removed from CVS
2971 3.feb.2001 and after that modified 18.feb.2001, so it reappered

3209 implemented patch 1120823 Thanks to Willy De la Court (normal
3210 interrupts need an interrupt number now if they are made critical),
3211 and enabled nesting of critical functions though not for gbz80
3212 (genCritical, genEndCritical): added functions
3213 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3214 * src/z80/mappings.i: added "ei" to all mappings

3226 the left operand is shorter than the result (c* = lit-c* + int),
3228 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3231 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3233 * src/.version: increased version number to 2.5.5
3234 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3235 linking is done manually in pic16 port's _linkEdit,
3236 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3237 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3238 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3239 allocate asmop as AOP_ACC,
3240 (aopForRemat): added parameter 'bool result' in function declaration,
3241 (pic16_aopGet): return AOP_ACC when accessing WREG,
3242 (pic16_popGetTempReg): minor modification,

3253 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3254 call to allocReg, not by manually allocating a new one,
3255 (pic16_assignRegisters): now before going through the register
3256 allocating functions mark all registers as free. This eliminates some
3257 side effects resulting from peephole parser done earlier in the backbone
3259 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3317 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3318 which dumps before the function entry point a data byte which represents
3319 the number of the local variables used by the specified function, added
3320 'xinst' for initial support for Extended Instruction Support,
3321 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3322 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3323 port->fun_prefix anymore (may change later),
3324 (genFunction, genEndFunction): do not store/restore local registers for
3325 _main (this should take care the --main-return command line option in
3327 (genOr): removed some legacy pic-port instructions,
3328 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3329 performing operations with SFR's causes data to be written more than
3330 once to each SFR. Perhaps SFRs should be handled in special cases...
3331 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3333 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3334 into account for stack starting position,

3336 --extended or -y for Extended Instruction Support,
3337 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3338 (deassignLRs): *** perhaps the most important change, old 'for' code
3339 (commented out for reference), didn't account for some registers which
3340 were left marked 'not free' after a pointer operation. The change
3341 reduces register usage a lot in some cases
3343 2006-03-04 Borut Razem <borut.razem AT siol.net>

5616 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5617 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5618 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5619 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5620 always available in leading double underscore form. The C99 support is
5621 mostly missing, but it's a start.
5622 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5623 reserved identifier "__data".
5625 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5701 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5703 * device/lib/printf_large.c: removed inline assembly for portability and
5704 readability. Use printf_fast if speed or size are more important.
5705 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5706 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5708 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5710 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5711 prevent compiler warning
5713 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5715 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5716 moved to level 0 and declared as static. Also they are explicit
5717 placed in access bank. This was necessery because some times they
5718 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5719 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5720 optimizations. Currently only compare to unsigned char is implemented,
5721 * src/pic16/gen.c: added fReturnIdx array,
5722 * (struct resolvedIfx) is moved to gen.h and made public,
5723 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5724 * (aopForSym): added an optimization to directly store in stack of
5725 the operand of a SEND iCode,
5726 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5727 but as registers instead (AOP_REG) using the fReturnIdx array,
5728 * (pic16_freeAsmop): remove the freed register from the
5729 _G.sregsAlloc field,
5730 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5731 a compare of 'WREG',
5732 * (pic16_popGetTempRegCond): changed function prototype, now
5733 function takes also a bitVector argument v which holds the current
5734 set of registers that are allocated for stack access by aopForSym,
5735 registers allocated in aopForSym for accessing stack symbols are not
5736 any more part of the functions usedRegs field,
5737 * (genCall): some times aopOp is called for a stack variable to be
5738 send, aopForSym might perform the push, if this is true make sure
5739 that genCall doesn't push the variable twice by testing _G.resDirect,
5740 * (genFunction): changed testing for unspecified interrupt number
5741 from 256 to INTNO_UNSPEC,
5742 * modified selection scheme of frame pointer generation. Previously
5743 if function did use local registers a frame pointer was generated,
5744 now a frame pointer is generated only if function has arguments
5745 (that need PLUSW2 register access), or has stack arguments, or the
5746 compiler is not instructed to omit the frame pointer,
5747 * (genEndFunction): before restoring local registers that were saved
5748 in the function preamble, also restore the registers that *might*
5749 have been allocated for stack access,
5750 * (genRet): removed some old comments,
5751 * (genCmp, the active (RN's) version): added a call to the
5752 pic16_genCmp_special function to perform the compare with a more
5753 robust and optimized way,
5754 * (genInline): a feature has been added in inline code generation,
5755 which allows a wildcard variable substitution when writing inline
5756 assembly. Code is incomplete and experimental therefore undocumented,
5757 * (genCast): changed order of aopOp for result and right to allow
5758 aopForSym to directly load the result if possible,
5759 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5760 perform an optimized compare on some selected special occasions,
5761 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5762 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5763 generate an IVT any more,
5764 * src/pic16/main.c (pic16_optionsTable): added command line option
5766 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5767 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5769 * src/pic16/NOTES: Raphael Neider added in list of active developers
5770 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5771 jumptable_end to prevent bug #,
5772 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5773 inCond and outCond fields,
5774 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5775 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5776 turn off register spilling,
5777 * (packRegsForOneUse): synced with other ports' versions although it
5778 is not used currently,
5779 * (pic16_packRegisters): added an optimization while reading
5780 structure bitfields, some registers may be saved (malloc code is
5781 decreased by 80 bytes)
5783 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5785 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5786 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5787 this can be optimized more?
5789 2005-03-10 Raphael Neider <rneider AT web.de>
5791 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5792 genNearPointerGet): (hopefully) fixed access to bitfields via
5793 pointers (p->bitN = x; and x = p->bitN; failed)
5795 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5836 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5838 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5839 to keep the correct label reference count when adding/removing references
5840 to labels. A peephole file using this is appended to patch #1144962.

5972 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5973 (sizeof(sectNames) changed to sizeof(sectName))
5974 Both patches fix segfaults under MinGW.
5976 2005-01-23 Raphael Neider <rneider AT web.de>
5978 * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
5979 Safe_[mc]?alloc()'ed variables
5980 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5981 of (byte sized) temporaries (assign them to WREG for now)
5982 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5983 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5984 this might fix SIGSEGVs on MinGW...
5985 * src/SDCCopt.c (killDeadCode): restored original behaviour
5986 (volatile operands might get thrown away though)
5988 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5990 * src/pic16/gen.c: fixed bug #1106975,

5995 * added function attribute 'shadowregs' to take advantage of shadow
5997 * added function attribute 'wparam' as an alternative to the wparam

6427 Adding support for replacing ljmps with sjmps in jumptables
6428 generated for switch statements. For now you need to set the
6429 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6430 Now 4 algorithms for mcs51 jumptable generation are used:
6431 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6432 addresses loaded pc-relative for up to 112 cases and stack-pushing
6433 target addresses loaded with offset from dptr for up to 256 cases.
6435 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6436 * src/mcs51/main.c: adapted constants for switch table generation
6437 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6452 * src/pic16/genarith.c,
6455 * src/pic16/pcode.c: applied patches #1068154 and #1070213
6457 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6459 Large cummulative patch for pic16 port.
6460 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6461 to call when a stack overflow occurs,
6462 * (malloc.h): added CVS Id tag,
6463 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6465 * added libc directory. The current version of LibC contains string
6466 functions, ctype functions and macros and some functions of the
6467 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6468 be extensively tested in the future. Standard disclaimer here.
6469 Library is not automatically build yet. But one can build it by
6470 invoking 'make' inside the libc directory.
6471 * added ADC library under libio. Preliminary version yet.
6473 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6474 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6475 aopForRemat() now and not by pic16_aopOp(),
6476 * (pic16_popGetTempReg): removed warning messgae when allocating
6477 temporary registers, its a buggy feature and will be removed,
6478 * (pic16_popGet): set register instance field in AOP_CRY,
6479 * (pic16_outBitC): fixed for results in size greater than 1,
6480 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6481 * (pic16_storeForReturn): optimized return of 0,
6482 * (genCmp): experimental code for new genCmp which uses PIC18's
6483 special compare&skip instructions. Initial tests fail some times
6484 with variables grater than 1 byte in size, so new code is disabled,
6485 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6487 * (genCast): began a fix to optimize the casting of a bit to another
6488 bit, now assigning a bitfield to another bitfield will fail, sorry,
6489 * src/pic16/main.c: disabled the use of lr-support feature,
6490 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6491 * added some function prototypes, added function _debugf prototype,
6492 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6493 bits with offset (case PO_GPR_BIT),
6494 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6496 * (isBankInstruction): modified to return 0 for no banking instruction,
6497 and 1 for banking instruction,
6498 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6499 caused stop processing pCodes after a inline assembly block,
6500 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6501 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6502 registers when it shouldn't,
6503 * src/pic16/ralloc.c (allocReg): add preliminary support for
6504 supporting a limited set of temporary registers,
6506 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6508 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6509 genDataPointerSet): ensure assignments always copy in MSB to LSB
6511 (loadRegFromAop): recognize CLRH optimization,
6512 (genFunction): optimize RECEIVE iCodes in reentrant functions
6514 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6516 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6517 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

6526 * device/lib/_gptrgetc.c (_gptrgetc),
6527 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6528 instead of sjmp to ret
6529 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6530 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6532 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9514 loaded with the linker search paths (-L arguments) and the libraries
9515 to be linked with the current source (-l arguments). Changes
9516 currently will affect only the pic16 port.
9517 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9518 include path the port specific paths and port specific libraries,

9525 initialization which bypassed the variable initializations block.
9527 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9528 COMPILE_FLAGS and added the --nostdinc option
9530 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9535 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9537 Documenting changes from previous commits.
9538 * configure.in (version 1.56),
9539 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9540 when generating output files to configure the pic16 library,
9541 but now I've commented it out, since gputils aren't installed in the
9542 SF compile farm, so library won't compile
9544 * device/lib/Makefile.in (version 1.56): initially I've added in
9545 target 'all' the prerequestive 'model-pic16' so it compiled the
9546 pic16 library, but now I've commented it out for the same reasons
9548 * added targets 'model-pic16' and 'objects-pic16' to compile the
9550 * added target 'port-specific-objects-pic16' to handle the
9551 generated libraries and copy them into the build/ directory
9552 * added target 'clean-intermediate-pic16' to clean intermediate
9553 files into pic16 directory
9554 * in target 'installdirs' added line to create directory pic16 in
9555 the installation path
9557 * device/include/Makefile.in (version 1.11): in target 'install'
9558 added lines to copy all header files to installation path,
9559 * in target 'installdirs' added line create directory for pic16
9560 headers in the installation path
9562 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

9575 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9576 option so that it actually works. Made it specific to the z80, since
9577 the gbz80 doesn't have these kinds of I/O ports.
9579 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9581 * device/include/z180.h,

9594 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9596 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9597 changed interrupt vector table generation to only emit declared vectors.
9598 * device/include/Makefile.in: added missing backslash
9599 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9603 Mainly changes to support compilation of the device libraries
9604 * src/pic16/device.c: stack is allocated via symbol and not
9605 via literal number. The symbol is placed in the corresponding
9606 position of the data ram
9607 * (pic16_dump_section): relocatable and absolute uninitialized
9608 data are now emitted in sorted order to reduce section naming,
9609 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9610 weren't marked as being in the access bank,
9612 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9614 Added portion of GNU PIC Library under the directory
9615 device/include/pic16 and device/lib/pic16. These files
9616 contain the declarations of SFRs for the PIC18Fxx2 devices.
9617 The directory is initialized via configure from toplevel.
9619 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9621 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9622 the spilllocations to be compared correctly
9624 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9626 * src/SDCCast.c (decorateType): fixed bug introduced today
9628 2004-01-12 Borut Razem <borut.razem AT siol.net>

9644 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9646 * doc/sdccman.lyx: Moved and added some sections, small changes
9647 all over. Telling LaTeX to be less strict with word spacing
9648 to better keep the right margin. Changed some notes about
9649 maintainance of the ports in section 3.2.1 - is it OK like this?
9651 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9653 SDCC source changes:
9654 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9688 UPPER for immediate operands,
9689 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9691 * src/pic16/peeph.def: all peepholes with movff are commented out,
9692 because there is a problem in the pcode peep optimizer,
9693 * src/pic16/ralloc.c: the register allocator can now reuse local
9694 function symbols for another function. This saves register usage.
9695 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9697 Added file src/pic16/NOTES with information about program writing on
9698 the current port version.

9730 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9733 * src/z80/main.c: added missed needLinkerScript flags (more than
9734 one port structure defined in these file)
9735 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9751 needLinkerScript flag
9753 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9754 * src/pic/glue.c: added variable udata_section_name to
9755 override default uninitialized data segment definition for

9757 * (pic14emitOverlay): modified to emit a commented overlay segment
9758 directive when no overlay data exist
9759 * (picglue): modified to emit uninitialized data segment
9760 according to udata_section_name

9770 2004-01-07 Borut Razem <borut.razem AT siol.net>
9772 * support/scripts/sdcc.nsi: update PATH
9773 * support/scripts/sdcc.ico: craeted

9786 include information about variables allocated to the overlay
9789 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9791 * as/mcs51/lkmain.c: Help about -Y option

9803 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9805 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9806 (default behaviour).
9808 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9810 A python script to validate compiler diagnostic messages. It can be
9811 used to verify that sdcc complains about bad c source code and
9812 gives a good location of the error.
9813 * support/valdiag/Makefile,
9814 * support/valdiag/valdiag.py,
9815 * support/valdiag/tests/*
9817 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9832 Bug reported from Jesus Calvino-Fraga
9834 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9836 * sdcc.spec: updated
9837 * device/include/Makefile.in: don't install CVS directories
9838 * device/lib/Makefile.in: added removal of CVS directories after install
9839 * doc/Makefile: fixed install, added local_icons
9840 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9841 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9842 * src/ds390/gen.c (genRightShift): fixed bug #870788
9843 * src/SDCCast.c (decorateType): fixed bug #870781
9845 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9847 PIC16 port related changes:
9848 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9849 added variable stackPos,
9851 * gen.c: genCall, assignResultValue: added support for
9852 pushing/retrieving function parameters to/from stack,
9853 genFunction,genEndFunction: setup stack frame for the
9855 genAddrOf: will be changed according to bug 863624
9857 * added files genutils.c and genutils.h which contain gen*
9858 debugged and optimised functions extracted from gen.c
9860 * glue.c: added variable 'externs' which holds extern symbols,
9861 pic16emitRegularMap: is modified to properly handle relocatable
9862 symbols under the new scheme,
9863 pic16createInterruptVect: is modified
9864 pic16printPublics: is modified to emit 'global' assembler directives,
9865 added pic16_printExterns to print extern symbols,
9866 pic16glue: initializes stack/frame pointer in the beginning of
9867 the assembly output. Temporary hack, will be corrected later,
9868 because gplink yet does not support stack and SDCC does not
9869 yet support a type of crt0.o object to create the final binary.
9871 * Removed many lines that contain 8051 legacy code.
9872 * The code is finally placed under a 'code' directive.
9873 * Added port specific options.
9875 * _process_pragma: simplified since now we do not need *special*
9876 include file to define SFR registers. But a separate header
9877 will be needed. This will be developed later.
9878 * _pic16_parseOptions: added, parses port specific options:
9879 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9880 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9881 --preplace-udata-with=
9883 * _pic16_setDefaultOptions: modified to initialize section names,
9884 but hack is temporarly out of order since it needs improvement.
9885 * _pic16_genAssemblerPreamble: configuration words are emitted by
9886 their address instead of their name. This part is incomplete and
9887 supports only the 18Fxx2 devices. Other devices will emit an error
9888 during assembly since they do not contain the same set of config
9890 * _pic16_genIVT: is modified,
9892 * pcode.c: added definitions for some hardware registers that are needed
9894 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9895 All PCI entries are updated. Now LFSR is supported.
9896 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9897 * added pic16_newpCodeOpLit2 to support instructions with
9898 two literal arguments
9899 * pic16_pCode2str: corrected code that emits assembler instructions
9900 with two literal operands and those that have an access bit modifier
9901 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9902 this fixes a bug which caused some labels to be lost, when an
9903 assembler directive was added, i.e. banksel,
9904 * pic16_FixRegisterBanking: improved logic that causes the insertion
9906 * InlineFunction: functions that are called once, are not any more
9907 inlined. This can be a port option in the future,
9909 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9911 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9912 hold the corresponding uninitialized symbols,
9913 * pic16_allocProcessorRegister: registers have explicit marked the
9915 * pic16_allocInternalRegister: registers are explicit marked as
9917 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9918 processing list, so bit registers were lost,
9921 * ralloc.h: added field 'accessBank' and original symbol operand
9922 in register definition,
9923 * removed the field isMapped from register definition,
9925 ** Several functions have been removed from various sources:
9926 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9927 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9928 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9929 pic16_assignRelocatableRegisters
9931 ** others have been introduced:
9932 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9933 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9935 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9937 * support/scripts/inc2h.pl: changed definition of BIT_AT
9938 to emit 'sbit at' instead of 'bit at'. This was a request.
9940 PIC16 port related preliminary changes:
9941 * gen.c: prefixed function popRegFromString with
9942 pic16_ and all references to it corrected
9943 * pcode.c: all pic16_pc_* hardware registers prefixed
9944 with underscore (_),
9945 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9946 * ralloc.c: newReg(): when register is REG_SFR then
9947 set address to rIdx,
9948 pic16_allocProcessorRegister(): marks register wasUsed=0
9949 pic16_writeUsedRegs(): added a call to assign processor
9950 registers via pic16_assignFixedRegisters
9952 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9954 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9955 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9956 variables in unused register banks. Also the SSEG is placed
9957 wherever there is enough space for it, and IDATA can be anywhere
9958 in internal RAM. For now compile using -Wl-Y[stack_size].
9959 The mem file is different for this option as well, since it
9960 makes no sense of talking about DSEG lenght.
9962 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9964 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9965 in certain cases, e.g. when ROM assignment, patch provided
9966 from Albert den Haan.
9968 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10963 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
10964 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
10965 before instructions that use the _STATUS register
10967 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10969 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10970 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10971 fetching of the pointer
10972 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10973 copied from genNearPointerSet()
10974 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10975 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10976 If they pop r0/r1 they must be called in the opposite order than aopOp().
10977 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10978 (resp. --stack-auto), prepared for --xstack
10980 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10982 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10984 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10986 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10987 these ports have their own __sdcc_external_start()
10989 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10991 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10992 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10993 type for bits was changed. It resulted in bit variables becoming
10994 global, which is not permitted in PIC 14 assembly output.
10996 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10998 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11000 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11002 Z80 and MCS51 linkers complaint if a public symbol is defined
11003 in more than one library module:
11007 * as/mcs51/Makefile.in
11009 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11011 A few small changes that speed up the peephole optimizer.
11015 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11017 Try to make the peephole optimizer smarter by maintaining
11018 an association between the assembly source code and the
11019 iCodes that originated them. Put this information to use
11020 with a new peephole rule condition "notVolatile" so that
11021 the rules can be aggressive yet still safe.
11026 * src/mcs51/peeph.def
11028 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11032 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11033 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11034 if the left or right operand symbols have the accuse flag set.
11036 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11038 Changed the type of the result of the ! (NOT) operator to char;
11039 previously it returned the same type as the source. This allows
11040 us to eliminate all the genFloatNot functions (all of its target
11041 implementations were very buggy) since !float can use the same
11044 * src/SDCCicode.c (ast2iCode): ! returns char
11045 * src/mcs51/gen.c (genNot, genNotFloat),
11046 * src/ds390/gen.c (genNot, genNotFloat),
11047 * src/z80/gen.c (genNot, genNotFloat),
11048 * src/pic/gen.c (genNot, genNotFloat),

11053 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11054 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11055 during interrupts. Ensure WSAVE is located at a shared bank address.
11056 2. Fixed page selection in some places
11057 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11058 the registers name strings.
11059 4. Fixed "signed / unsigned compare" compiler warnings.
11060 5. The PIC port manages its own allocation of the general purpose
11061 registers, but makes no attempt to reuse them. As a result when
11062 compiling it soon runs out of general purpose registers. Some
11063 additional code was added to the files pcode.c and device.c to walk
11064 through the function call tree and rename the registers so that they
11074 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11075 genPlus() & genMinus() when the result is the same as left or right
11077 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11081 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11083 Made bitfield a distinct type from bit so that bitfields
11084 convert as per ANSI C and bits retain their traditional
11085 boolean style behaviour. Implemented bitfield support in
11093 * src/ds390/gen.c: bit v bitfield split
11094 * src/z80/gen.c: New support for bitfields
11095 * support/regression/tests/bitfields.c: reenabled z80,
11098 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11100 Rules 246.x, 247.x relate to bitfields, the others speed up
11101 access to xdata mapped I/O devices.
11103 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11105 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11107 Cleaned up genPackBits and genUnpackBits and added two helper
11108 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11109 for literal assignments in genPackBits (thanks to Frieder for
11115 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11117 Fixed bug #748310 (pointer to function type mishandled when the
11118 function name is omitted). Also fixed a SIGSEGV when a function
11119 attribute (reentrant, etc) is used on a non-function or on a
11120 function but misplaced before the parameter list.
11122 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11124 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11125 * support/Util/SDCCerr.h,
11126 * support/Util/SDCCerr.c: Added func attr misuse error msg
11128 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11130 Fixed bug #787649 by anonymous
11131 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11132 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11134 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11136 Fixed numerous bitfield problems.

11147 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11149 Made the constant following the "interrupt" keyword optional. If
11150 omitted, the function will not automatically be given an entry
11151 in the interrupt vector table (similar to #pragma NOIV, but
11152 less syntacticly kludgy). The interrupt number is also now
11153 range checked. Also fixed a bug in the high order bit example
11160 * support/Util/SDCCerr.c
11161 * support/Util/SDCCerr.h

11169 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11171 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11172 be re-activated by defining REDUCE_LITERALS)
11173 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11174 unsigned, but are signed by default
11175 * src/SDCCval.c (constVal): rearranged
11176 * src/SDCCval.c (valMod): preliminary fix
11177 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11217 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11218 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11219 constants are unsigned; added recognition of "u" flag for unsigned
11220 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11221 * src/SDCCval.c (valDiv, valMod): fixed signdness

11629 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11630 the regression tests I'm not brave enough to enable 245.b, 245.c
11631 * doc/sdccman.lyx: added latex preamble for hyperref package.
11632 Using pdflatex this will give you a hyperlinked pdf file with
11633 bookmarks. (prepend '%' before /usepackage if this breaks something)

11683 added if/endif conditional macros to remove options help
11684 messages from optionsTable when a port is not configured, added
11685 support for the PIc16 port in the ports table, when executing
11686 the compiler with no port specified on command line, a default
11687 port is selected with the new macro DEFAULT_PORT which is
11688 defined in port.h, in setDefaultOptions() linkOptions is removed
11689 from initialization assignment, since now it is a set,
11690 parseCmdLine uses setParseWithComma for linkOptions, in
11691 linkEdit() linkOptions are accessed with new function indexSet()
11692 which returns the i'th item of a set variable. See SDCCset.c, in
11693 linkEdit() when calling buildCmdLine(), added linkOptions as
11694 last argument. Now users can pass arguments to gplink via the
11695 -Wl option, main() uses pic16glue() to glue up pic16 programs

11707 * src/pic16/glue.c: commented out some error producing lines
11708 * src/pic16/main.c: __config directives are commented out to stop
11709 gpasm complaining and test the linkage with gplink, _linkCmd and
11710 _asmCmd changed to be more gplink and gpasm friendly
11711 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11712 produced an error when parsed, peep rule 12 is added to utilize
11713 movff, but it is commented out since the pCode does not support
11714 yet a command with 2 address arguments
11716 2003-05-18 <johan AT balder>
11718 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12795 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12797 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12800 2002-09-18 <wiml AT hhhh.org>
12802 * SDCClrange.h: exposed setFromRange() and setToRange()
12803 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12804 packRegsForAccUse() (bug 542397)
12805 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12806 multiple times and emitting the fetch operations more than once
12807 added aopGetUsesAcc() function to allow binary operators to
12808 fetch their operands in the correct order; made genMinus() emit
12809 compact code for X = LITERAL - Y
12811 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12812 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12813 sprintf() in line 1267.
12815 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12816 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12819 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12820 Changes to aslink (All the changes are marked with 'JCF'):
12822 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12825 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12826 area BSEG. Also moves, if possible, the DATA area down into the internal
12827 ram so more space is available.
12829 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12832 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12833 not bytes. Function summary() which creates a memory usage summary
12834 file with extension .mem. Reports of overlaping stack and small stack
12835 size. If the space for the stack is less than 16 bytes aslink trows a
12838 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12839 the 8051. Option 'y' for memory summary output file.
12841 Changes to sdcc (All the changes are marked with 'JCF'):
12843 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12845 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12846 overlaying area for it (uses RegBankUsed[4]).
12848 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12849 bank zero as used by default. By default aslink locates the stack
12850 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12851 the creation of the .mem file. Delegates the allocation of data area
12852 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12853 the begining of the stack area to aslink.
12855 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12856 glue() in SDCCglue.c creates an area for it.
12858 2002-09-03 Borut Razem <borut.razem AT siol.net>
12859 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12860 sdcc/src/pic/glue.c:
12861 introduced atexit() handler for teporay files removal in case of
12862 errors, assertions, ...
12864 2002-08-29 Borut Razem <borut.razem AT siol.net>
12865 * sdcc/support/cpp2/auto-host_vc_in.h:
12866 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12867 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12868 Maybe there is a similar problem with BORLANDC? It should be checked!
12870 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12871 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12872 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12873 was not executed, and the compiler (cl) launched a warning:
12874 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12876 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12877 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12879 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12880 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12882 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12883 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12884 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12885 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12886 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12887 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12888 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12889 - added Release configuration in VS projects
12890 - review of compiler an linker options
12891 - VC .exe files are generated in bin_vc directory, not to interfere
12892 with binaries generated from other projects (cygwin, mingw, bcc ...)
12894 * sdcc/src/yacc.dsp: added
12896 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12897 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12898 and insert the version number definitions from .version
12900 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12902 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12903 added - genarate auto-host.h using auto-host_vc_in.h as template
12906 removed from CVS, generated automatically
12908 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12909 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12911 2002-08-11 Borut Razem <borut.razem AT siol.net>
12912 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12914 2002-08-10 Borut Razem <borut.razem AT siol.net>
12915 * src/SDCCmain.c (main):
12916 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12917 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12918 The consequence was that some temporary files were not removed.
12921 unification of code in functions tempfilename() and tempfile():
12922 function tempnam() is defined in Visual Studio 6.0 and .NET
12924 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12926 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12927 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12928 - removed compiler command line option /WX: Treats all warnings as errors
12929 - update a list of source files, included into the project
12931 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12932 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12933 changed project type to Generic Project so that can be correcly converted to VS.NET project
12935 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12937 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12939 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12941 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12942 added return 0 statements after assert() to make compiler happy
12944 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12945 added newline in the def file to keep MSC compiler satisfied
12947 * sdcc/src/z80/gen.c:
12948 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12949 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12950 - solved MSC error in function aopDump()
12952 * sdcc_vc.h: define PREFIX as "\\sdcc"
12954 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12955 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12958 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12959 - Rewrote the register banking algorithm.
12960 - Added pCode live-range analysis to registers (for now, only non-used and
12961 singly-used registers optimized away)
12963 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12965 * 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.

12990 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12992 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12994 2002-03-28 Johan Knol <johan AT balder>
12996 * src/SDCCval.c: fixed bug #532436
12998 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13000 Added "char *Processor" field to the port structure.
13003 Added -p option. Allows port dependent processor to be specified.
13006 Initialized the new field char *Processor field to NULL in all ports
13009 Compiler generated registers for interrupt context saving
13010 were not getting allocated.
13012 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13015 Fixed left shift. Will promote the left side of a left shift
13016 if a) left shifting more than size of operand or b) when assigned
13017 to something size > size of left side
13019 2002-03-14 Scott Dattalo <scott AT dattalo.com>

13023 analysis is restructured. ...
13025 * src/pic/device.h:
13028 * src/pic/device.c:
13029 Added. device.c is a PIC port hack to accomodate variations
13032 2002-03-13 Michael Hope <michaelh AT vroom>
13034 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13036 2002-03-04 johanknol <johanknol AT manik>
13038 * /src/SDCCval.c: fixed
13040 const unsigned char arr[][2] = { { 0, 1 } };

13127 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13129 * sdcc/src/SDCCloop.c:
13130 Previous fix was not good. basic blocks that have "break" or "return" are
13131 not really partof a loop , but live ranges used in these blocks should
13132 be live thru the entire loop, so set partOfLoop but don't add them to
13135 2002-02-21 <johan AT FRIJA>
13137 * src/SDCCcse.c: fixed bug #514308
13139 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

13143 statement inside a loop, it was not being considered part of the loop.
13145 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13147 2002-02-10 Karl Bongers <karl AT turbobit.com>
