2898 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2900 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2901 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2903 One basic decision: e.g. src/clean.mk includes further files. In order
2904 to make this work there are two solutions:
2905 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2906 run configure on them. This way they can use
2907 'include $(srcdir)/port-clean.mk'
2908 - always include clean.mk by the Makefile at the same level. To avoid
2909 that `make clean` tries to include and build Makefile.dep the
2910 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2911 implemented, because now even `make uninstall` doesn't create
2912 Makefile.in. clean.mk could be eliminated by pasting it in
2915 * debugger/mcs51/Makefile.in: build own objects from library sources
2916 (SLIB, SDCC) in current directory
2918 * configure, configure.in: renamed --disable-device-lib-build in
2919 --disable-device-lib; added --enable-doc, the required tools are
2920 searched by configure; added result message; the toolchain for the
2921 belonging ports are now only built, if the port is enabled.
2923 * support/regression/*: all output is written in directory gen, because
2924 the fwk and ports directories don't livet in the build tree using vpath
2926 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2927 --disable-device-lib, added --enable-doc, added section VPATH
2929 * sim/ucsim/configure.in,
2930 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2931 z80 are enabled by default
2933 2006-04-24 Raphael Neider <rneider AT web.de>
2935 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2936 to config word, "pic14_"-prefixed some extern functions
2937 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2938 config word has been found
2939 * src/pic/device.h: added prototypes
2940 * src/pic/pcode.c: added "pic14_"-prefix where needed
2941 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2943 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2946 (pic14createInterruptVect): moved generating __config directives away
2947 (picglue): have __config directives emitted
2949 2006-04-24 Borut Razem <borut.razem AT siol.net>

2957 fixes #1469504 and #1474602,
2958 (pCodeRegOptimizeRegUsage): fixed typo in comment

2962 * device/examples/main8051.c: deleted - it was removed from CVS

2964 after the transition to Subversion
2965 * src/SDCCalloc.h: deleted - it was removed from CVS
2966 3.feb.2001 and after that modified 18.feb.2001, so it reappered

3204 implemented patch 1120823 Thanks to Willy De la Court (normal
3205 interrupts need an interrupt number now if they are made critical),
3206 and enabled nesting of critical functions though not for gbz80
3207 (genCritical, genEndCritical): added functions
3208 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3209 * src/z80/mappings.i: added "ei" to all mappings

3221 the left operand is shorter than the result (c* = lit-c* + int),
3223 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3226 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3228 * src/.version: increased version number to 2.5.5
3229 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3230 linking is done manually in pic16 port's _linkEdit,
3231 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3232 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3233 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3234 allocate asmop as AOP_ACC,
3235 (aopForRemat): added parameter 'bool result' in function declaration,
3236 (pic16_aopGet): return AOP_ACC when accessing WREG,
3237 (pic16_popGetTempReg): minor modification,

3248 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3249 call to allocReg, not by manually allocating a new one,
3250 (pic16_assignRegisters): now before going through the register
3251 allocating functions mark all registers as free. This eliminates some
3252 side effects resulting from peephole parser done earlier in the backbone
3254 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3312 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3313 which dumps before the function entry point a data byte which represents
3314 the number of the local variables used by the specified function, added
3315 'xinst' for initial support for Extended Instruction Support,
3316 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3317 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3318 port->fun_prefix anymore (may change later),
3319 (genFunction, genEndFunction): do not store/restore local registers for
3320 _main (this should take care the --main-return command line option in
3322 (genOr): removed some legacy pic-port instructions,
3323 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3324 performing operations with SFR's causes data to be written more than
3325 once to each SFR. Perhaps SFRs should be handled in special cases...
3326 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3328 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3329 into account for stack starting position,

3331 --extended or -y for Extended Instruction Support,
3332 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3333 (deassignLRs): *** perhaps the most important change, old 'for' code
3334 (commented out for reference), didn't account for some registers which
3335 were left marked 'not free' after a pointer operation. The change
3336 reduces register usage a lot in some cases
3338 2006-03-04 Borut Razem <borut.razem AT siol.net>
3340 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5603 on rIfx (genCmp was broken)
5605 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5607 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5608 * src/z80/main.c (_keywords[]),
5609 * src/SDCCglobal.h (struct options),
5611 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5612 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5613 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5614 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5615 always available in leading double underscore form. The C99 support is
5616 mostly missing, but it's a start.
5617 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5618 reserved identifier "__data".
5620 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
5622 * src/mcs51/peeph.def: fixed bug 1170013

5633 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5635 * src/port.h (struct PORT),

5664 immedDom() returning wrong block; probably fixes bug #1160833)
5666 2005-03-20 Borut Razem <borut.razem AT siol.net>
5668 * support/scripts/inc2h.pl: WIN32 port
5670 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5672 * device/lib/makefile.in: added abs.c and labs.c
5674 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5676 * device/include/stdint.h: added
5677 * device/lib/abs.c: added

5696 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5698 * device/lib/printf_large.c: removed inline assembly for portability and
5699 readability. Use printf_fast if speed or size are more important.
5700 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5701 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5703 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5705 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5706 prevent compiler warning
5708 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5710 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5711 moved to level 0 and declared as static. Also they are explicit
5712 placed in access bank. This was necessery because some times they
5713 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5714 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5715 optimizations. Currently only compare to unsigned char is implemented,
5716 * src/pic16/gen.c: added fReturnIdx array,
5717 * (struct resolvedIfx) is moved to gen.h and made public,
5718 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5719 * (aopForSym): added an optimization to directly store in stack of
5720 the operand of a SEND iCode,
5721 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5722 but as registers instead (AOP_REG) using the fReturnIdx array,
5723 * (pic16_freeAsmop): remove the freed register from the
5724 _G.sregsAlloc field,
5725 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5726 a compare of 'WREG',
5727 * (pic16_popGetTempRegCond): changed function prototype, now
5728 function takes also a bitVector argument v which holds the current
5729 set of registers that are allocated for stack access by aopForSym,
5730 registers allocated in aopForSym for accessing stack symbols are not
5731 any more part of the functions usedRegs field,
5732 * (genCall): some times aopOp is called for a stack variable to be
5733 send, aopForSym might perform the push, if this is true make sure
5734 that genCall doesn't push the variable twice by testing _G.resDirect,
5735 * (genFunction): changed testing for unspecified interrupt number
5736 from 256 to INTNO_UNSPEC,
5737 * modified selection scheme of frame pointer generation. Previously
5738 if function did use local registers a frame pointer was generated,
5739 now a frame pointer is generated only if function has arguments
5740 (that need PLUSW2 register access), or has stack arguments, or the
5741 compiler is not instructed to omit the frame pointer,
5742 * (genEndFunction): before restoring local registers that were saved
5743 in the function preamble, also restore the registers that *might*
5744 have been allocated for stack access,
5745 * (genRet): removed some old comments,
5746 * (genCmp, the active (RN's) version): added a call to the
5747 pic16_genCmp_special function to perform the compare with a more
5748 robust and optimized way,
5749 * (genInline): a feature has been added in inline code generation,
5750 which allows a wildcard variable substitution when writing inline
5751 assembly. Code is incomplete and experimental therefore undocumented,
5752 * (genCast): changed order of aopOp for result and right to allow
5753 aopForSym to directly load the result if possible,
5754 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5755 perform an optimized compare on some selected special occasions,
5756 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5757 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5758 generate an IVT any more,
5759 * src/pic16/main.c (pic16_optionsTable): added command line option
5761 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5762 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5764 * src/pic16/NOTES: Raphael Neider added in list of active developers
5765 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5766 jumptable_end to prevent bug #,
5767 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5768 inCond and outCond fields,
5769 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5770 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5771 turn off register spilling,
5772 * (packRegsForOneUse): synced with other ports' versions although it
5773 is not used currently,
5774 * (pic16_packRegisters): added an optimization while reading
5775 structure bitfields, some registers may be saved (malloc code is
5776 decreased by 80 bytes)
5778 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5780 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5781 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5782 this can be optimized more?
5784 2005-03-10 Raphael Neider <rneider AT web.de>
5786 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5787 genNearPointerGet): (hopefully) fixed access to bitfields via
5788 pointers (p->bitN = x; and x = p->bitN; failed)
5790 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5833 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5834 to keep the correct label reference count when adding/removing references
5835 to labels. A peephole file using this is appended to patch #1144962.
5837 2005-02-14 Raphael Neider <rneider AT web.de>

5967 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5968 (sizeof(sectNames) changed to sizeof(sectName))
5969 Both patches fix segfaults under MinGW.

5974 Safe_[mc]?alloc()'ed variables
5975 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5976 of (byte sized) temporaries (assign them to WREG for now)
5977 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5978 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5979 this might fix SIGSEGVs on MinGW...
5980 * src/SDCCopt.c (killDeadCode): restored original behaviour
5981 (volatile operands might get thrown away though)
5983 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5985 * src/pic16/gen.c: fixed bug #1106975,

5990 * added function attribute 'shadowregs' to take advantage of shadow
5992 * added function attribute 'wparam' as an alternative to the wparam
5994 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
5995 user declares a non-ISR function as 'shadowregs',

6424 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6425 Now 4 algorithms for mcs51 jumptable generation are used:
6426 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6427 addresses loaded pc-relative for up to 112 cases and stack-pushing
6428 target addresses loaded with offset from dptr for up to 256 cases.
6430 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6431 * src/mcs51/main.c: adapted constants for switch table generation
6432 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp
6434 2004-11-26 Maarten Brock <sourceforge.brock AT dse.nl>
6436 * device/lib/printf_large.c (_print_format): fixed bug 1073386
6437 * support/regression/tests/bug1057979.c: added test for bug 1073386
6439 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
6441 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
6444 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
6446 * src/pic16/device.h,
6447 * src/pic16/genarith.c,
6450 * src/pic16/pcode.c: applied patches #1068154 and #1070213
6452 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6454 Large cummulative patch for pic16 port.
6455 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6456 to call when a stack overflow occurs,
6457 * (malloc.h): added CVS Id tag,
6458 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6460 * added libc directory. The current version of LibC contains string
6461 functions, ctype functions and macros and some functions of the
6462 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6463 be extensively tested in the future. Standard disclaimer here.
6464 Library is not automatically build yet. But one can build it by
6465 invoking 'make' inside the libc directory.
6466 * added ADC library under libio. Preliminary version yet.
6468 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6469 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6470 aopForRemat() now and not by pic16_aopOp(),
6471 * (pic16_popGetTempReg): removed warning messgae when allocating
6472 temporary registers, its a buggy feature and will be removed,
6473 * (pic16_popGet): set register instance field in AOP_CRY,
6474 * (pic16_outBitC): fixed for results in size greater than 1,
6475 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6476 * (pic16_storeForReturn): optimized return of 0,
6477 * (genCmp): experimental code for new genCmp which uses PIC18's
6478 special compare&skip instructions. Initial tests fail some times
6479 with variables grater than 1 byte in size, so new code is disabled,
6480 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6482 * (genCast): began a fix to optimize the casting of a bit to another
6483 bit, now assigning a bitfield to another bitfield will fail, sorry,
6484 * src/pic16/main.c: disabled the use of lr-support feature,
6485 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6486 * added some function prototypes, added function _debugf prototype,
6487 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6488 bits with offset (case PO_GPR_BIT),
6489 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6491 * (isBankInstruction): modified to return 0 for no banking instruction,
6492 and 1 for banking instruction,
6493 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6494 caused stop processing pCodes after a inline assembly block,
6495 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6496 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6497 registers when it shouldn't,
6498 * src/pic16/ralloc.c (allocReg): add preliminary support for
6499 supporting a limited set of temporary registers,
6501 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6503 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6504 genDataPointerSet): ensure assignments always copy in MSB to LSB
6506 (loadRegFromAop): recognize CLRH optimization,
6507 (genFunction): optimize RECEIVE iCodes in reentrant functions
6509 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6511 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6512 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6514 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6523 instead of sjmp to ret
6524 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6525 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6527 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9509 loaded with the linker search paths (-L arguments) and the libraries
9510 to be linked with the current source (-l arguments). Changes
9511 currently will affect only the pic16 port.
9512 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9513 include path the port specific paths and port specific libraries,

9530 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9532 Documenting changes from previous commits.
9533 * configure.in (version 1.56),
9534 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9535 when generating output files to configure the pic16 library,
9536 but now I've commented it out, since gputils aren't installed in the
9537 SF compile farm, so library won't compile
9539 * device/lib/Makefile.in (version 1.56): initially I've added in
9540 target 'all' the prerequestive 'model-pic16' so it compiled the
9541 pic16 library, but now I've commented it out for the same reasons
9543 * added targets 'model-pic16' and 'objects-pic16' to compile the
9545 * added target 'port-specific-objects-pic16' to handle the
9546 generated libraries and copy them into the build/ directory
9547 * added target 'clean-intermediate-pic16' to clean intermediate
9548 files into pic16 directory
9549 * in target 'installdirs' added line to create directory pic16 in
9550 the installation path
9552 * device/include/Makefile.in (version 1.11): in target 'install'
9553 added lines to copy all header files to installation path,
9554 * in target 'installdirs' added line create directory for pic16
9555 headers in the installation path
9557 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

9570 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9571 option so that it actually works. Made it specific to the z80, since
9572 the gbz80 doesn't have these kinds of I/O ports.
9574 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9576 * device/include/z180.h,

9589 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9591 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9592 changed interrupt vector table generation to only emit declared vectors.

9598 Mainly changes to support compilation of the device libraries
9599 * src/pic16/device.c: stack is allocated via symbol and not
9600 via literal number. The symbol is placed in the corresponding
9601 position of the data ram
9602 * (pic16_dump_section): relocatable and absolute uninitialized
9603 data are now emitted in sorted order to reduce section naming,
9604 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9605 weren't marked as being in the access bank,
9607 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9609 Added portion of GNU PIC Library under the directory
9610 device/include/pic16 and device/lib/pic16. These files
9611 contain the declarations of SFRs for the PIC18Fxx2 devices.
9612 The directory is initialized via configure from toplevel.
9614 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9616 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9617 the spilllocations to be compared correctly
9619 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9621 * src/SDCCast.c (decorateType): fixed bug introduced today
9623 2004-01-12 Borut Razem <borut.razem AT siol.net>

9641 * doc/sdccman.lyx: Moved and added some sections, small changes
9642 all over. Telling LaTeX to be less strict with word spacing
9643 to better keep the right margin. Changed some notes about
9644 maintainance of the ports in section 3.2.1 - is it OK like this?
9646 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9648 SDCC source changes:
9649 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9683 UPPER for immediate operands,
9684 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9686 * src/pic16/peeph.def: all peepholes with movff are commented out,
9687 because there is a problem in the pcode peep optimizer,
9688 * src/pic16/ralloc.c: the register allocator can now reuse local

9690 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9692 Added file src/pic16/NOTES with information about program writing on
9693 the current port version.

9722 gen51Code): more efficient parameter receive for --model-large
9725 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9728 * src/z80/main.c: added missed needLinkerScript flags (more than
9729 one port structure defined in these file)
9730 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9746 needLinkerScript flag
9748 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9749 * src/pic/glue.c: added variable udata_section_name to
9750 override default uninitialized data segment definition for
9751 devices only with SHAREBANK memory (reported from Erik Epetrich)
9752 * (pic14emitOverlay): modified to emit a commented overlay segment
9753 directive when no overlay data exist
9754 * (picglue): modified to emit uninitialized data segment
9755 according to udata_section_name

9761 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9762 object file from '.rel' to '.o' in port->linker structure,
9763 changed size of fptr from 2 to 3 in port structure
9765 2004-01-07 Borut Razem <borut.razem AT siol.net>
9767 * support/scripts/sdcc.nsi: update PATH
9768 * support/scripts/sdcc.ico: craeted

9781 include information about variables allocated to the overlay
9784 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9786 * as/mcs51/lkmain.c: Help about -Y option

9798 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9800 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9801 (default behaviour).
9803 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9805 A python script to validate compiler diagnostic messages. It can be
9806 used to verify that sdcc complains about bad c source code and
9807 gives a good location of the error.
9808 * support/valdiag/Makefile,
9809 * support/valdiag/valdiag.py,
9810 * support/valdiag/tests/*

9827 Bug reported from Jesus Calvino-Fraga
9829 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9831 * sdcc.spec: updated
9832 * device/include/Makefile.in: don't install CVS directories
9833 * device/lib/Makefile.in: added removal of CVS directories after install
9834 * doc/Makefile: fixed install, added local_icons
9835 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9836 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9837 * src/ds390/gen.c (genRightShift): fixed bug #870788
9838 * src/SDCCast.c (decorateType): fixed bug #870781
9840 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9842 PIC16 port related changes:
9843 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9844 added variable stackPos,
9846 * gen.c: genCall, assignResultValue: added support for
9847 pushing/retrieving function parameters to/from stack,
9848 genFunction,genEndFunction: setup stack frame for the
9850 genAddrOf: will be changed according to bug 863624
9852 * added files genutils.c and genutils.h which contain gen*
9853 debugged and optimised functions extracted from gen.c
9855 * glue.c: added variable 'externs' which holds extern symbols,
9856 pic16emitRegularMap: is modified to properly handle relocatable
9857 symbols under the new scheme,
9858 pic16createInterruptVect: is modified
9859 pic16printPublics: is modified to emit 'global' assembler directives,
9860 added pic16_printExterns to print extern symbols,
9861 pic16glue: initializes stack/frame pointer in the beginning of
9862 the assembly output. Temporary hack, will be corrected later,
9863 because gplink yet does not support stack and SDCC does not
9864 yet support a type of crt0.o object to create the final binary.
9866 * Removed many lines that contain 8051 legacy code.
9867 * The code is finally placed under a 'code' directive.
9868 * Added port specific options.
9870 * _process_pragma: simplified since now we do not need *special*
9871 include file to define SFR registers. But a separate header
9872 will be needed. This will be developed later.
9873 * _pic16_parseOptions: added, parses port specific options:
9874 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9875 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9876 --preplace-udata-with=
9878 * _pic16_setDefaultOptions: modified to initialize section names,
9879 but hack is temporarly out of order since it needs improvement.
9880 * _pic16_genAssemblerPreamble: configuration words are emitted by
9881 their address instead of their name. This part is incomplete and
9882 supports only the 18Fxx2 devices. Other devices will emit an error
9883 during assembly since they do not contain the same set of config
9885 * _pic16_genIVT: is modified,
9887 * pcode.c: added definitions for some hardware registers that are needed
9889 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9890 All PCI entries are updated. Now LFSR is supported.
9891 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9892 * added pic16_newpCodeOpLit2 to support instructions with
9893 two literal arguments
9894 * pic16_pCode2str: corrected code that emits assembler instructions
9895 with two literal operands and those that have an access bit modifier
9896 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9897 this fixes a bug which caused some labels to be lost, when an
9898 assembler directive was added, i.e. banksel,
9899 * pic16_FixRegisterBanking: improved logic that causes the insertion
9901 * InlineFunction: functions that are called once, are not any more
9902 inlined. This can be a port option in the future,
9904 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9906 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9907 hold the corresponding uninitialized symbols,
9908 * pic16_allocProcessorRegister: registers have explicit marked the
9910 * pic16_allocInternalRegister: registers are explicit marked as
9912 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9913 processing list, so bit registers were lost,
9916 * ralloc.h: added field 'accessBank' and original symbol operand
9917 in register definition,
9918 * removed the field isMapped from register definition,
9920 ** Several functions have been removed from various sources:
9921 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9922 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9923 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9924 pic16_assignRelocatableRegisters
9926 ** others have been introduced:
9927 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9928 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9930 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9932 * support/scripts/inc2h.pl: changed definition of BIT_AT
9933 to emit 'sbit at' instead of 'bit at'. This was a request.
9935 PIC16 port related preliminary changes:
9936 * gen.c: prefixed function popRegFromString with
9937 pic16_ and all references to it corrected
9938 * pcode.c: all pic16_pc_* hardware registers prefixed
9939 with underscore (_),
9940 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9941 * ralloc.c: newReg(): when register is REG_SFR then
9942 set address to rIdx,
9943 pic16_allocProcessorRegister(): marks register wasUsed=0
9944 pic16_writeUsedRegs(): added a call to assign processor
9945 registers via pic16_assignFixedRegisters
9947 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9949 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9950 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9951 variables in unused register banks. Also the SSEG is placed
9952 wherever there is enough space for it, and IDATA can be anywhere
9953 in internal RAM. For now compile using -Wl-Y[stack_size].
9954 The mem file is different for this option as well, since it
9955 makes no sense of talking about DSEG lenght.
9957 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9959 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9960 in certain cases, e.g. when ROM assignment, patch provided
9961 from Albert den Haan.
9963 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10962 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10964 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10965 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10966 fetching of the pointer
10967 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10968 copied from genNearPointerSet()
10969 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10970 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10971 If they pop r0/r1 they must be called in the opposite order than aopOp().
10972 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10973 (resp. --stack-auto), prepared for --xstack
10975 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10977 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10979 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10981 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10982 these ports have their own __sdcc_external_start()
10984 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10986 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10987 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10988 type for bits was changed. It resulted in bit variables becoming
10989 global, which is not permitted in PIC 14 assembly output.
10991 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10993 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10995 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10997 Z80 and MCS51 linkers complaint if a public symbol is defined
10998 in more than one library module:

11004 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11006 A few small changes that speed up the peephole optimizer.
11010 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11012 Try to make the peephole optimizer smarter by maintaining
11013 an association between the assembly source code and the
11014 iCodes that originated them. Put this information to use
11015 with a new peephole rule condition "notVolatile" so that
11016 the rules can be aggressive yet still safe.
11021 * src/mcs51/peeph.def
11023 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11027 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11028 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11029 if the left or right operand symbols have the accuse flag set.
11031 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11033 Changed the type of the result of the ! (NOT) operator to char;
11034 previously it returned the same type as the source. This allows
11035 us to eliminate all the genFloatNot functions (all of its target
11036 implementations were very buggy) since !float can use the same
11039 * src/SDCCicode.c (ast2iCode): ! returns char
11040 * src/mcs51/gen.c (genNot, genNotFloat),
11041 * src/ds390/gen.c (genNot, genNotFloat),
11042 * src/z80/gen.c (genNot, genNotFloat),
11043 * src/pic/gen.c (genNot, genNotFloat),
11044 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11048 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11049 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11050 during interrupts. Ensure WSAVE is located at a shared bank address.
11051 2. Fixed page selection in some places
11052 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11053 the registers name strings.
11054 4. Fixed "signed / unsigned compare" compiler warnings.
11055 5. The PIC port manages its own allocation of the general purpose
11056 registers, but makes no attempt to reuse them. As a result when
11057 compiling it soon runs out of general purpose registers. Some
11058 additional code was added to the files pcode.c and device.c to walk
11059 through the function call tree and rename the registers so that they
11069 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11070 genPlus() & genMinus() when the result is the same as left or right
11072 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11076 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11078 Made bitfield a distinct type from bit so that bitfields
11079 convert as per ANSI C and bits retain their traditional
11080 boolean style behaviour. Implemented bitfield support in
11088 * src/ds390/gen.c: bit v bitfield split
11089 * src/z80/gen.c: New support for bitfields
11090 * support/regression/tests/bitfields.c: reenabled z80,
11093 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11095 Rules 246.x, 247.x relate to bitfields, the others speed up
11096 access to xdata mapped I/O devices.
11098 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11100 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11102 Cleaned up genPackBits and genUnpackBits and added two helper
11103 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11104 for literal assignments in genPackBits (thanks to Frieder for
11110 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11112 Fixed bug #748310 (pointer to function type mishandled when the
11113 function name is omitted). Also fixed a SIGSEGV when a function
11114 attribute (reentrant, etc) is used on a non-function or on a
11115 function but misplaced before the parameter list.
11117 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11119 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11120 * support/Util/SDCCerr.h,
11121 * support/Util/SDCCerr.c: Added func attr misuse error msg
11123 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11125 Fixed bug #787649 by anonymous
11126 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11127 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11129 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11131 Fixed numerous bitfield problems.

11142 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11144 Made the constant following the "interrupt" keyword optional. If
11145 omitted, the function will not automatically be given an entry
11146 in the interrupt vector table (similar to #pragma NOIV, but
11147 less syntacticly kludgy). The interrupt number is also now
11148 range checked. Also fixed a bug in the high order bit example

11156 * support/Util/SDCCerr.h
11159 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11164 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11166 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11167 be re-activated by defining REDUCE_LITERALS)
11168 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11169 unsigned, but are signed by default
11170 * src/SDCCval.c (constVal): rearranged
11171 * src/SDCCval.c (valMod): preliminary fix
11172 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11212 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11213 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11214 constants are unsigned; added recognition of "u" flag for unsigned
11215 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11216 * src/SDCCval.c (valDiv, valMod): fixed signdness

11624 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11625 the regression tests I'm not brave enough to enable 245.b, 245.c
11626 * doc/sdccman.lyx: added latex preamble for hyperref package.
11627 Using pdflatex this will give you a hyperlinked pdf file with
11628 bookmarks. (prepend '%' before /usepackage if this breaks something)

11669 it can be defined with CFLAGS when running configure
11670 * src/SDCCmain.c: fixed compiling + linking with object files
11672 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

11677 * src/SDCCmain.c: linkOptions is changed to set *,
11678 added if/endif conditional macros to remove options help
11679 messages from optionsTable when a port is not configured, added
11680 support for the PIc16 port in the ports table, when executing
11681 the compiler with no port specified on command line, a default
11682 port is selected with the new macro DEFAULT_PORT which is
11683 defined in port.h, in setDefaultOptions() linkOptions is removed
11684 from initialization assignment, since now it is a set,
11685 parseCmdLine uses setParseWithComma for linkOptions, in
11686 linkEdit() linkOptions are accessed with new function indexSet()
11687 which returns the i'th item of a set variable. See SDCCset.c, in
11688 linkEdit() when calling buildCmdLine(), added linkOptions as
11689 last argument. Now users can pass arguments to gplink via the
11690 -Wl option, main() uses pic16glue() to glue up pic16 programs
11691 * src/SDCCpeeph.c: various changes to support pic16
11692 * src/SDCCset.c: added function void *indexSet(set *, int) to

11702 * src/pic16/glue.c: commented out some error producing lines
11703 * src/pic16/main.c: __config directives are commented out to stop
11704 gpasm complaining and test the linkage with gplink, _linkCmd and
11705 _asmCmd changed to be more gplink and gpasm friendly
11706 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11707 produced an error when parsed, peep rule 12 is added to utilize
11708 movff, but it is commented out since the pCode does not support
11709 yet a command with 2 address arguments
11711 2003-05-18 <johan AT balder>
11713 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12795 2002-09-18 <wiml AT hhhh.org>
12797 * SDCClrange.h: exposed setFromRange() and setToRange()
12798 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12799 packRegsForAccUse() (bug 542397)
12800 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12801 multiple times and emitting the fetch operations more than once
12802 added aopGetUsesAcc() function to allow binary operators to
12803 fetch their operands in the correct order; made genMinus() emit
12804 compact code for X = LITERAL - Y
12806 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12807 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12808 sprintf() in line 1267.
12810 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12811 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12814 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12815 Changes to aslink (All the changes are marked with 'JCF'):
12817 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12820 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12821 area BSEG. Also moves, if possible, the DATA area down into the internal
12822 ram so more space is available.
12824 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12827 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12828 not bytes. Function summary() which creates a memory usage summary
12829 file with extension .mem. Reports of overlaping stack and small stack
12830 size. If the space for the stack is less than 16 bytes aslink trows a
12833 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12834 the 8051. Option 'y' for memory summary output file.
12836 Changes to sdcc (All the changes are marked with 'JCF'):
12838 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12840 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12841 overlaying area for it (uses RegBankUsed[4]).
12843 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12844 bank zero as used by default. By default aslink locates the stack
12845 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12846 the creation of the .mem file. Delegates the allocation of data area
12847 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12848 the begining of the stack area to aslink.
12850 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12851 glue() in SDCCglue.c creates an area for it.
12853 2002-09-03 Borut Razem <borut.razem AT siol.net>
12854 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12855 sdcc/src/pic/glue.c:
12856 introduced atexit() handler for teporay files removal in case of
12857 errors, assertions, ...
12859 2002-08-29 Borut Razem <borut.razem AT siol.net>
12860 * sdcc/support/cpp2/auto-host_vc_in.h:
12861 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12862 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12863 Maybe there is a similar problem with BORLANDC? It should be checked!
12865 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12866 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12867 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12868 was not executed, and the compiler (cl) launched a warning:
12869 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12871 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12872 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12874 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12875 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12877 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12878 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12879 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12880 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12881 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12882 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12883 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12884 - added Release configuration in VS projects
12885 - review of compiler an linker options
12886 - VC .exe files are generated in bin_vc directory, not to interfere
12887 with binaries generated from other projects (cygwin, mingw, bcc ...)
12889 * sdcc/src/yacc.dsp: added
12891 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12892 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12893 and insert the version number definitions from .version
12895 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12897 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12898 added - genarate auto-host.h using auto-host_vc_in.h as template
12901 removed from CVS, generated automatically
12903 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12904 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12906 2002-08-11 Borut Razem <borut.razem AT siol.net>
12907 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12909 2002-08-10 Borut Razem <borut.razem AT siol.net>
12910 * src/SDCCmain.c (main):
12911 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12912 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12913 The consequence was that some temporary files were not removed.
12916 unification of code in functions tempfilename() and tempfile():
12917 function tempnam() is defined in Visual Studio 6.0 and .NET
12919 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12921 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12922 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12923 - removed compiler command line option /WX: Treats all warnings as errors
12924 - update a list of source files, included into the project
12926 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12927 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12928 changed project type to Generic Project so that can be correcly converted to VS.NET project
12930 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12932 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12934 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12936 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12937 added return 0 statements after assert() to make compiler happy
12939 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12940 added newline in the def file to keep MSC compiler satisfied
12942 * sdcc/src/z80/gen.c:
12943 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12944 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12945 - solved MSC error in function aopDump()
12947 * sdcc_vc.h: define PREFIX as "\\sdcc"
12949 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12950 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12953 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12954 - Rewrote the register banking algorithm.
12955 - Added pCode live-range analysis to registers (for now, only non-used and
12956 singly-used registers optimized away)
12958 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12960 * 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.

12985 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12987 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12989 2002-03-28 Johan Knol <johan AT balder>
12991 * src/SDCCval.c: fixed bug #532436
12993 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12995 Added "char *Processor" field to the port structure.
12998 Added -p option. Allows port dependent processor to be specified.
13001 Initialized the new field char *Processor field to NULL in all ports
13004 Compiler generated registers for interrupt context saving
13005 were not getting allocated.
13007 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13010 Fixed left shift. Will promote the left side of a left shift
13011 if a) left shifting more than size of operand or b) when assigned
13012 to something size > size of left side
13014 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13016 tons of changes. Register allocation has been

13018 analysis is restructured. ...
13020 * src/pic/device.h:
13023 * src/pic/device.c:
13024 Added. device.c is a PIC port hack to accomodate variations
13027 2002-03-13 Michael Hope <michaelh AT vroom>
13029 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13031 2002-03-04 johanknol <johanknol AT manik>
13033 * /src/SDCCval.c: fixed
13035 const unsigned char arr[][2] = { { 0, 1 } };

13122 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13124 * sdcc/src/SDCCloop.c:
13125 Previous fix was not good. basic blocks that have "break" or "return" are
13126 not really partof a loop , but live ranges used in these blocks should
13127 be live thru the entire loop, so set partOfLoop but don't add them to
13130 2002-02-21 <johan AT FRIJA>
13132 * src/SDCCcse.c: fixed bug #514308
13134 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13137 Fixed BUG #519583. If a conditional block ended in a return/break
13138 statement inside a loop, it was not being considered part of the loop.
13140 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13142 2002-02-10 Karl Bongers <karl AT turbobit.com>
