1414 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1415 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1416 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1417 always available in leading double underscore form. The C99 support is
1418 mostly missing, but it's a start.
1419 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1498 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1500 * device/lib/printf_large.c: removed inline assembly for portability and
1501 readability. Use printf_fast if speed or size are more important.
1502 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1503 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1505 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1507 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1508 prevent compiler warning
1510 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1512 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1513 moved to level 0 and declared as static. Also they are explicit
1514 placed in access bank. This was necessery because some times they
1515 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1516 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1517 optimizations. Currently only compare to unsigned char is implemented,
1518 * src/pic16/gen.c: added fReturnIdx array,
1519 * (struct resolvedIfx) is moved to gen.h and made public,
1520 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1521 * (aopForSym): added an optimization to directly store in stack of
1522 the operand of a SEND iCode,
1523 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1524 but as registers instead (AOP_REG) using the fReturnIdx array,
1525 * (pic16_freeAsmop): remove the freed register from the
1526 _G.sregsAlloc field,
1527 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1528 a compare of 'WREG',
1529 * (pic16_popGetTempRegCond): changed function prototype, now
1530 function takes also a bitVector argument v which holds the current
1531 set of registers that are allocated for stack access by aopForSym,
1532 registers allocated in aopForSym for accessing stack symbols are not
1533 any more part of the functions usedRegs field,
1534 * (genCall): some times aopOp is called for a stack variable to be
1535 send, aopForSym might perform the push, if this is true make sure
1536 that genCall doesn't push the variable twice by testing _G.resDirect,
1537 * (genFunction): changed testing for unspecified interrupt number
1538 from 256 to INTNO_UNSPEC,
1539 * modified selection scheme of frame pointer generation. Previously
1540 if function did use local registers a frame pointer was generated,
1541 now a frame pointer is generated only if function has arguments
1542 (that need PLUSW2 register access), or has stack arguments, or the
1543 compiler is not instructed to omit the frame pointer,
1544 * (genEndFunction): before restoring local registers that were saved
1545 in the function preamble, also restore the registers that *might*
1546 have been allocated for stack access,
1547 * (genRet): removed some old comments,
1548 * (genCmp, the active (RN's) version): added a call to the
1549 pic16_genCmp_special function to perform the compare with a more
1550 robust and optimized way,
1551 * (genInline): a feature has been added in inline code generation,
1552 which allows a wildcard variable substitution when writing inline
1553 assembly. Code is incomplete and experimental therefore undocumented,
1554 * (genCast): changed order of aopOp for result and right to allow
1555 aopForSym to directly load the result if possible,
1556 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1557 perform an optimized compare on some selected special occasions,
1558 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1559 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1560 generate an IVT any more,
1561 * src/pic16/main.c (pic16_optionsTable): added command line option
1563 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1564 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1566 * src/pic16/NOTES: Raphael Neider added in list of active developers
1567 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1568 jumptable_end to prevent bug #,
1569 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1570 inCond and outCond fields,
1571 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1572 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1573 turn off register spilling,
1574 * (packRegsForOneUse): synced with other ports' versions although it
1575 is not used currently,
1576 * (pic16_packRegisters): added an optimization while reading
1577 structure bitfields, some registers may be saved (malloc code is
1578 decreased by 80 bytes)
1580 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1582 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1583 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1584 this can be optimized more?
1586 2005-03-10 Raphael Neider <rneider AT web.de>
1588 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1589 genNearPointerGet): (hopefully) fixed access to bitfields via
1590 pointers (p->bitN = x; and x = p->bitN; failed)

2224 Adding support for replacing ljmps with sjmps in jumptables
2225 generated for switch statements. For now you need to set the
2226 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2227 Now 4 algorithms for mcs51 jumptable generation are used:
2228 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2229 addresses loaded pc-relative for up to 112 cases and stack-pushing
2230 target addresses loaded with offset from dptr for up to 256 cases.

2257 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2258 to call when a stack overflow occurs,
2259 * (malloc.h): added CVS Id tag,
2260 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2262 * added libc directory. The current version of LibC contains string
2263 functions, ctype functions and macros and some functions of the
2264 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2265 be extensively tested in the future. Standard disclaimer here.
2266 Library is not automatically build yet. But one can build it by
2267 invoking 'make' inside the libc directory.
2268 * added ADC library under libio. Preliminary version yet.
2270 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2277 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2278 * (pic16_storeForReturn): optimized return of 0,
2279 * (genCmp): experimental code for new genCmp which uses PIC18's
2280 special compare&skip instructions. Initial tests fail some times
2281 with variables grater than 1 byte in size, so new code is disabled,
2282 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2284 * (genCast): began a fix to optimize the casting of a bit to another
2285 bit, now assigning a bitfield to another bitfield will fail, sorry,
2286 * src/pic16/main.c: disabled the use of lr-support feature,
2287 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2290 bits with offset (case PO_GPR_BIT),
2291 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2293 * (isBankInstruction): modified to return 0 for no banking instruction,
2294 and 1 for banking instruction,
2295 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2296 caused stop processing pCodes after a inline assembly block,
2297 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2298 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2299 registers when it shouldn't,
2300 * src/pic16/ralloc.c (allocReg): add preliminary support for
2301 supporting a limited set of temporary registers,
2303 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2305 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2306 genDataPointerSet): ensure assignments always copy in MSB to LSB
2308 (loadRegFromAop): recognize CLRH optimization,
2309 (genFunction): optimize RECEIVE iCodes in reentrant functions
2311 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2313 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5308 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5310 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5311 loaded with the linker search paths (-L arguments) and the libraries
5312 to be linked with the current source (-l arguments). Changes
5313 currently will affect only the pic16 port.
5314 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5315 include path the port specific paths and port specific libraries,
5316 * gplink command now contains the $3 argument,
5317 * src/pic16/device.h,
5318 * src/pic16/device.c,: structure PIC_device is made public and
5319 renamed to PIC16_device, the same for variable Pics which is renamed
5320 to Pics16. Updated all references to them.

5332 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5334 Documenting changes from previous commits.
5335 * configure.in (version 1.56),
5336 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5337 when generating output files to configure the pic16 library,
5338 but now I've commented it out, since gputils aren't installed in the
5339 SF compile farm, so library won't compile
5341 * device/lib/Makefile.in (version 1.56): initially I've added in
5342 target 'all' the prerequestive 'model-pic16' so it compiled the
5343 pic16 library, but now I've commented it out for the same reasons
5345 * added targets 'model-pic16' and 'objects-pic16' to compile the
5347 * added target 'port-specific-objects-pic16' to handle the
5348 generated libraries and copy them into the build/ directory
5349 * added target 'clean-intermediate-pic16' to clean intermediate
5350 files into pic16 directory
5351 * in target 'installdirs' added line to create directory pic16 in
5352 the installation path
5354 * device/include/Makefile.in (version 1.11): in target 'install'
5355 added lines to copy all header files to installation path,
5356 * in target 'installdirs' added line create directory for pic16
5357 headers in the installation path

5372 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5373 option so that it actually works. Made it specific to the z80, since
5374 the gbz80 doesn't have these kinds of I/O ports.
5376 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5378 * device/include/z180.h,

5391 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5393 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5394 changed interrupt vector table generation to only emit declared vectors.
5395 * device/include/Makefile.in: added missing backslash
5396 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5398 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5400 Mainly changes to support compilation of the device libraries
5401 * src/pic16/device.c: stack is allocated via symbol and not
5402 via literal number. The symbol is placed in the corresponding
5403 position of the data ram
5404 * (pic16_dump_section): relocatable and absolute uninitialized
5405 data are now emitted in sorted order to reduce section naming,
5406 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5407 weren't marked as being in the access bank,
5409 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5411 Added portion of GNU PIC Library under the directory
5412 device/include/pic16 and device/lib/pic16. These files
5413 contain the declarations of SFRs for the PIC18Fxx2 devices.
5414 The directory is initialized via configure from toplevel.
5416 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5418 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5419 the spilllocations to be compared correctly
5421 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5423 * src/SDCCast.c (decorateType): fixed bug introduced today
5425 2004-01-12 Borut Razem <borut.razem AT siol.net>
5427 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5430 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5432 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5433 in simpler and even better code
5435 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5437 * src/SDCCicode.c (operandOperation): fixed bug #874819

5443 * doc/sdccman.lyx: Moved and added some sections, small changes
5444 all over. Telling LaTeX to be less strict with word spacing
5445 to better keep the right margin. Changed some notes about
5446 maintainance of the ports in section 3.2.1 - is it OK like this?
5448 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5485 UPPER for immediate operands,
5486 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5488 * src/pic16/peeph.def: all peepholes with movff are commented out,
5489 because there is a problem in the pcode peep optimizer,
5490 * src/pic16/ralloc.c: the register allocator can now reuse local
5491 function symbols for another function. This saves register usage.
5492 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5494 Added file src/pic16/NOTES with information about program writing on
5495 the current port version.

5524 gen51Code): more efficient parameter receive for --model-large
5527 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5530 * src/z80/main.c: added missed needLinkerScript flags (more than
5531 one port structure defined in these file)
5532 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5548 needLinkerScript flag
5550 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5551 * src/pic/glue.c: added variable udata_section_name to
5552 override default uninitialized data segment definition for
5553 devices only with SHAREBANK memory (reported from Erik Epetrich)
5554 * (pic14emitOverlay): modified to emit a commented overlay segment
5555 directive when no overlay data exist
5556 * (picglue): modified to emit uninitialized data segment
5557 according to udata_section_name

5563 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5564 object file from '.rel' to '.o' in port->linker structure,
5565 changed size of fptr from 2 to 3 in port structure
5567 2004-01-07 Borut Razem <borut.razem AT siol.net>
5569 * support/scripts/sdcc.nsi: update PATH
5570 * support/scripts/sdcc.ico: craeted
5572 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5583 include information about variables allocated to the overlay
5586 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5588 * as/mcs51/lkmain.c: Help about -Y option

5600 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5602 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5603 (default behaviour).
5605 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5607 A python script to validate compiler diagnostic messages. It can be
5608 used to verify that sdcc complains about bad c source code and
5609 gives a good location of the error.
5610 * support/valdiag/Makefile,
5611 * support/valdiag/valdiag.py,
5612 * support/valdiag/tests/*
5614 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5627 * src/common.h: added ifndef/define/endif macros
5628 around the header file.
5629 Bug reported from Jesus Calvino-Fraga
5631 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5633 * sdcc.spec: updated
5634 * device/include/Makefile.in: don't install CVS directories
5635 * device/lib/Makefile.in: added removal of CVS directories after install
5636 * doc/Makefile: fixed install, added local_icons
5637 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5638 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5639 * src/ds390/gen.c (genRightShift): fixed bug #870788
5640 * src/SDCCast.c (decorateType): fixed bug #870781
5642 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5644 PIC16 port related changes:
5645 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5646 added variable stackPos,
5648 * gen.c: genCall, assignResultValue: added support for
5649 pushing/retrieving function parameters to/from stack,
5650 genFunction,genEndFunction: setup stack frame for the
5652 genAddrOf: will be changed according to bug 863624
5654 * added files genutils.c and genutils.h which contain gen*
5655 debugged and optimised functions extracted from gen.c
5657 * glue.c: added variable 'externs' which holds extern symbols,
5658 pic16emitRegularMap: is modified to properly handle relocatable
5659 symbols under the new scheme,
5660 pic16createInterruptVect: is modified
5661 pic16printPublics: is modified to emit 'global' assembler directives,
5662 added pic16_printExterns to print extern symbols,
5663 pic16glue: initializes stack/frame pointer in the beginning of
5664 the assembly output. Temporary hack, will be corrected later,
5665 because gplink yet does not support stack and SDCC does not
5666 yet support a type of crt0.o object to create the final binary.
5668 * Removed many lines that contain 8051 legacy code.
5669 * The code is finally placed under a 'code' directive.
5670 * Added port specific options.
5672 * _process_pragma: simplified since now we do not need *special*
5673 include file to define SFR registers. But a separate header
5674 will be needed. This will be developed later.
5675 * _pic16_parseOptions: added, parses port specific options:
5676 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5677 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5678 --preplace-udata-with=
5680 * _pic16_setDefaultOptions: modified to initialize section names,
5681 but hack is temporarly out of order since it needs improvement.
5682 * _pic16_genAssemblerPreamble: configuration words are emitted by
5683 their address instead of their name. This part is incomplete and
5684 supports only the 18Fxx2 devices. Other devices will emit an error
5685 during assembly since they do not contain the same set of config
5687 * _pic16_genIVT: is modified,
5689 * pcode.c: added definitions for some hardware registers that are needed
5691 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5692 All PCI entries are updated. Now LFSR is supported.
5693 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5694 * added pic16_newpCodeOpLit2 to support instructions with
5695 two literal arguments
5696 * pic16_pCode2str: corrected code that emits assembler instructions
5697 with two literal operands and those that have an access bit modifier
5698 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5699 this fixes a bug which caused some labels to be lost, when an
5700 assembler directive was added, i.e. banksel,
5701 * pic16_FixRegisterBanking: improved logic that causes the insertion
5703 * InlineFunction: functions that are called once, are not any more
5704 inlined. This can be a port option in the future,
5706 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5708 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5709 hold the corresponding uninitialized symbols,
5710 * pic16_allocProcessorRegister: registers have explicit marked the
5712 * pic16_allocInternalRegister: registers are explicit marked as
5714 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5715 processing list, so bit registers were lost,
5718 * ralloc.h: added field 'accessBank' and original symbol operand
5719 in register definition,
5720 * removed the field isMapped from register definition,
5722 ** Several functions have been removed from various sources:
5723 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5724 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5725 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5726 pic16_assignRelocatableRegisters
5728 ** others have been introduced:
5729 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5730 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5732 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5734 * support/scripts/inc2h.pl: changed definition of BIT_AT
5735 to emit 'sbit at' instead of 'bit at'. This was a request.
5737 PIC16 port related preliminary changes:
5738 * gen.c: prefixed function popRegFromString with
5739 pic16_ and all references to it corrected
5740 * pcode.c: all pic16_pc_* hardware registers prefixed
5741 with underscore (_),
5742 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5743 * ralloc.c: newReg(): when register is REG_SFR then
5744 set address to rIdx,
5745 pic16_allocProcessorRegister(): marks register wasUsed=0
5746 pic16_writeUsedRegs(): added a call to assign processor
5747 registers via pic16_assignFixedRegisters
5749 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5751 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5752 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5753 variables in unused register banks. Also the SSEG is placed
5754 wherever there is enough space for it, and IDATA can be anywhere
5755 in internal RAM. For now compile using -Wl-Y[stack_size].
5756 The mem file is different for this option as well, since it
5757 makes no sense of talking about DSEG lenght.

6752 and JUMPTABLE iCodes properly now (worked by accident before)
6753 * src/mcs51/gen.c (leftRightUseAcc),
6754 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
6755 iCode properly now. Use getSize instead of nRegs since a & b
6756 aren't part of the nRegs tally.
6758 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
6760 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
6761 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
6762 before instructions that use the _STATUS register
6764 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
6766 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6767 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6768 fetching of the pointer
6769 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6770 copied from genNearPointerSet()
6771 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6772 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6773 If they pop r0/r1 they must be called in the opposite order than aopOp().
6774 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6775 (resp. --stack-auto), prepared for --xstack
6777 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6781 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6783 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6784 these ports have their own __sdcc_external_start()
6786 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6788 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6789 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6790 type for bits was changed. It resulted in bit variables becoming
6791 global, which is not permitted in PIC 14 assembly output.
6793 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6795 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6797 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6799 Z80 and MCS51 linkers complaint if a public symbol is defined
6800 in more than one library module:
6804 * as/mcs51/Makefile.in
6806 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6808 A few small changes that speed up the peephole optimizer.
6812 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6814 Try to make the peephole optimizer smarter by maintaining
6815 an association between the assembly source code and the
6816 iCodes that originated them. Put this information to use
6817 with a new peephole rule condition "notVolatile" so that
6818 the rules can be aggressive yet still safe.
6823 * src/mcs51/peeph.def
6825 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6829 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6830 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6831 if the left or right operand symbols have the accuse flag set.
6833 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6835 Changed the type of the result of the ! (NOT) operator to char;
6836 previously it returned the same type as the source. This allows
6837 us to eliminate all the genFloatNot functions (all of its target
6838 implementations were very buggy) since !float can use the same
6841 * src/SDCCicode.c (ast2iCode): ! returns char
6842 * src/mcs51/gen.c (genNot, genNotFloat),
6843 * src/ds390/gen.c (genNot, genNotFloat),
6844 * src/z80/gen.c (genNot, genNotFloat),
6845 * src/pic/gen.c (genNot, genNotFloat),
6846 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6848 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6850 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6851 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6852 during interrupts. Ensure WSAVE is located at a shared bank address.
6853 2. Fixed page selection in some places
6854 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6855 the registers name strings.
6856 4. Fixed "signed / unsigned compare" compiler warnings.
6857 5. The PIC port manages its own allocation of the general purpose
6858 registers, but makes no attempt to reuse them. As a result when
6859 compiling it soon runs out of general purpose registers. Some
6860 additional code was added to the files pcode.c and device.c to walk
6861 through the function call tree and rename the registers so that they
6871 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6872 genPlus() & genMinus() when the result is the same as left or right

6878 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6880 Made bitfield a distinct type from bit so that bitfields
6881 convert as per ANSI C and bits retain their traditional
6882 boolean style behaviour. Implemented bitfield support in
6890 * src/ds390/gen.c: bit v bitfield split
6891 * src/z80/gen.c: New support for bitfields
6892 * support/regression/tests/bitfields.c: reenabled z80,
6895 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6897 Rules 246.x, 247.x relate to bitfields, the others speed up
6898 access to xdata mapped I/O devices.
6900 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6902 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6904 Cleaned up genPackBits and genUnpackBits and added two helper
6905 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6906 for literal assignments in genPackBits (thanks to Frieder for
6912 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6914 Fixed bug #748310 (pointer to function type mishandled when the
6915 function name is omitted). Also fixed a SIGSEGV when a function
6916 attribute (reentrant, etc) is used on a non-function or on a
6917 function but misplaced before the parameter list.
6919 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6921 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6922 * support/Util/SDCCerr.h,
6923 * support/Util/SDCCerr.c: Added func attr misuse error msg
6925 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6927 Fixed bug #787649 by anonymous
6928 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6944 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6946 Made the constant following the "interrupt" keyword optional. If
6947 omitted, the function will not automatically be given an entry
6948 in the interrupt vector table (similar to #pragma NOIV, but
6949 less syntacticly kludgy). The interrupt number is also now
6950 range checked. Also fixed a bug in the high order bit example
6957 * support/Util/SDCCerr.c
6958 * support/Util/SDCCerr.h
6961 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6964 * src/SDCCicode.c (operandOperation): rewritten some ops
6965 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6966 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6968 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6969 be re-activated by defining REDUCE_LITERALS)
6970 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6971 unsigned, but are signed by default
6972 * src/SDCCval.c (constVal): rearranged
6973 * src/SDCCval.c (valMod): preliminary fix
6974 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7017 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7018 * src/SDCCval.c (valDiv, valMod): fixed signdness
7019 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7020 signedness of modulo, left and right shift

7426 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7427 the regression tests I'm not brave enough to enable 245.b, 245.c
7428 * doc/sdccman.lyx: added latex preamble for hyperref package.
7429 Using pdflatex this will give you a hyperlinked pdf file with
7430 bookmarks. (prepend '%' before /usepackage if this breaks something)

7446 Applied patch from bug 737905 (renamed yylineo to mylineno):
7453 * src/pic16/pcode.c: Cleaned warnings
7454 * src/pic16/pcodeflow.c: Cleaned warnings
7455 * src/pic16/pcoderegs.c: Cleaned warnings

7468 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7470 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7471 it can be defined with CFLAGS when running configure
7472 * src/SDCCmain.c: fixed compiling + linking with object files
7474 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7477 added --disable-pic16-port
7478 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7479 * src/SDCCmain.c: linkOptions is changed to set *,
7480 added if/endif conditional macros to remove options help
7481 messages from optionsTable when a port is not configured, added
7482 support for the PIc16 port in the ports table, when executing
7483 the compiler with no port specified on command line, a default
7484 port is selected with the new macro DEFAULT_PORT which is
7485 defined in port.h, in setDefaultOptions() linkOptions is removed
7486 from initialization assignment, since now it is a set,
7487 parseCmdLine uses setParseWithComma for linkOptions, in
7488 linkEdit() linkOptions are accessed with new function indexSet()
7489 which returns the i'th item of a set variable. See SDCCset.c, in
7490 linkEdit() when calling buildCmdLine(), added linkOptions as
7491 last argument. Now users can pass arguments to gplink via the
7492 -Wl option, main() uses pic16glue() to glue up pic16 programs

7504 * src/pic16/glue.c: commented out some error producing lines
7505 * src/pic16/main.c: __config directives are commented out to stop
7506 gpasm complaining and test the linkage with gplink, _linkCmd and
7507 _asmCmd changed to be more gplink and gpasm friendly
7508 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7509 produced an error when parsed, peep rule 12 is added to utilize
7510 movff, but it is commented out since the pCode does not support
7511 yet a command with 2 address arguments
7513 2003-05-18 <johan AT balder>
7515 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7516 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7540 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7542 2003-05-11 Borut Razem <borut.razem AT siol.net>
7544 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7545 the path of bin directory, so that PATH is the only env. variable, which has to be set
7546 in case of standard installation.
7547 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8576 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8578 * in \sdcc\as\mcs51\ changed these files in order to create an
8579 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8580 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8581 following files to include the previous two files: aslink.dsp,
8582 Makefile.aslink, Makefile.bcc, and Makefile.in.
8584 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8585 .adb instead of .cdb
8587 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8589 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8590 value from option --iram-size.
8592 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8594 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8597 2002-09-18 <wiml AT hhhh.org>
8599 * SDCClrange.h: exposed setFromRange() and setToRange()
8600 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8601 packRegsForAccUse() (bug 542397)
8602 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8603 multiple times and emitting the fetch operations more than once
8604 added aopGetUsesAcc() function to allow binary operators to
8605 fetch their operands in the correct order; made genMinus() emit
8606 compact code for X = LITERAL - Y
8608 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8609 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8610 sprintf() in line 1267.
8612 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8613 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8616 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8617 Changes to aslink (All the changes are marked with 'JCF'):
8619 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8622 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8623 area BSEG. Also moves, if possible, the DATA area down into the internal
8624 ram so more space is available.
8626 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8629 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8630 not bytes. Function summary() which creates a memory usage summary
8631 file with extension .mem. Reports of overlaping stack and small stack
8632 size. If the space for the stack is less than 16 bytes aslink trows a
8635 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8636 the 8051. Option 'y' for memory summary output file.
8638 Changes to sdcc (All the changes are marked with 'JCF'):
8640 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8642 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8643 overlaying area for it (uses RegBankUsed[4]).
8645 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8646 bank zero as used by default. By default aslink locates the stack
8647 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8648 the creation of the .mem file. Delegates the allocation of data area
8649 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8650 the begining of the stack area to aslink.
8652 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8653 glue() in SDCCglue.c creates an area for it.
8655 2002-09-03 Borut Razem <borut.razem AT siol.net>
8656 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8657 sdcc/src/pic/glue.c:
8658 introduced atexit() handler for teporay files removal in case of
8659 errors, assertions, ...
8661 2002-08-29 Borut Razem <borut.razem AT siol.net>
8662 * sdcc/support/cpp2/auto-host_vc_in.h:
8663 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8664 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8665 Maybe there is a similar problem with BORLANDC? It should be checked!
8667 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8668 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8669 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8670 was not executed, and the compiler (cl) launched a warning:
8671 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8673 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

8681 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8682 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8683 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8684 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8685 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8686 - added Release configuration in VS projects
8687 - review of compiler an linker options
8688 - VC .exe files are generated in bin_vc directory, not to interfere
8689 with binaries generated from other projects (cygwin, mingw, bcc ...)
8691 * sdcc/src/yacc.dsp: added
8693 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8694 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8695 and insert the version number definitions from .version
8697 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8699 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8709 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8711 2002-08-10 Borut Razem <borut.razem AT siol.net>
8712 * src/SDCCmain.c (main):
8713 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8714 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8715 The consequence was that some temporary files were not removed.
8718 unification of code in functions tempfilename() and tempfile():
8719 function tempnam() is defined in Visual Studio 6.0 and .NET
8721 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8723 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8724 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

8738 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8739 added return 0 statements after assert() to make compiler happy
8741 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8742 added newline in the def file to keep MSC compiler satisfied
8744 * sdcc/src/z80/gen.c:
8745 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8746 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8747 - solved MSC error in function aopDump()
8749 * sdcc_vc.h: define PREFIX as "\\sdcc"
8751 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8806 Compiler generated registers for interrupt context saving
8807 were not getting allocated.
8809 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8812 Fixed left shift. Will promote the left side of a left shift
8813 if a) left shifting more than size of operand or b) when assigned
8814 to something size > size of left side
8816 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8924 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8926 * sdcc/src/SDCCloop.c:
8927 Previous fix was not good. basic blocks that have "break" or "return" are
8928 not really partof a loop , but live ranges used in these blocks should
8929 be live thru the entire loop, so set partOfLoop but don't add them to
8932 2002-02-21 <johan AT FRIJA>
8934 * src/SDCCcse.c: fixed bug #514308
8936 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
