1366 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1368 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

1372 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1373 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1374 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1375 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1376 always available in leading double underscore form. The C99 support is
1377 mostly missing, but it's a start.
1378 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1379 reserved identifier "__data".
1381 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1425 immedDom() returning wrong block; probably fixes bug #1160833)
1427 2005-03-20 Borut Razem <borut.razem AT siol.net>
1429 * support/scripts/inc2h.pl: WIN32 port

1457 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1459 * device/lib/printf_large.c: removed inline assembly for portability and
1460 readability. Use printf_fast if speed or size are more important.
1461 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1462 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1464 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1466 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1467 prevent compiler warning
1469 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1471 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1472 moved to level 0 and declared as static. Also they are explicit
1473 placed in access bank. This was necessery because some times they
1474 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1475 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1476 optimizations. Currently only compare to unsigned char is implemented,
1477 * src/pic16/gen.c: added fReturnIdx array,
1478 * (struct resolvedIfx) is moved to gen.h and made public,
1479 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1480 * (aopForSym): added an optimization to directly store in stack of
1481 the operand of a SEND iCode,
1482 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1483 but as registers instead (AOP_REG) using the fReturnIdx array,
1484 * (pic16_freeAsmop): remove the freed register from the
1485 _G.sregsAlloc field,
1486 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1487 a compare of 'WREG',
1488 * (pic16_popGetTempRegCond): changed function prototype, now
1489 function takes also a bitVector argument v which holds the current
1490 set of registers that are allocated for stack access by aopForSym,
1491 registers allocated in aopForSym for accessing stack symbols are not
1492 any more part of the functions usedRegs field,
1493 * (genCall): some times aopOp is called for a stack variable to be
1494 send, aopForSym might perform the push, if this is true make sure
1495 that genCall doesn't push the variable twice by testing _G.resDirect,
1496 * (genFunction): changed testing for unspecified interrupt number
1497 from 256 to INTNO_UNSPEC,
1498 * modified selection scheme of frame pointer generation. Previously
1499 if function did use local registers a frame pointer was generated,
1500 now a frame pointer is generated only if function has arguments
1501 (that need PLUSW2 register access), or has stack arguments, or the
1502 compiler is not instructed to omit the frame pointer,
1503 * (genEndFunction): before restoring local registers that were saved
1504 in the function preamble, also restore the registers that *might*
1505 have been allocated for stack access,
1506 * (genRet): removed some old comments,
1507 * (genCmp, the active (RN's) version): added a call to the
1508 pic16_genCmp_special function to perform the compare with a more
1509 robust and optimized way,
1510 * (genInline): a feature has been added in inline code generation,
1511 which allows a wildcard variable substitution when writing inline
1512 assembly. Code is incomplete and experimental therefore undocumented,
1513 * (genCast): changed order of aopOp for result and right to allow
1514 aopForSym to directly load the result if possible,
1515 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1516 perform an optimized compare on some selected special occasions,
1517 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1518 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1519 generate an IVT any more,
1520 * src/pic16/main.c (pic16_optionsTable): added command line option
1522 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1523 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1525 * src/pic16/NOTES: Raphael Neider added in list of active developers
1526 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1527 jumptable_end to prevent bug #,
1528 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1529 inCond and outCond fields,
1530 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1531 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1532 turn off register spilling,
1533 * (packRegsForOneUse): synced with other ports' versions although it
1534 is not used currently,
1535 * (pic16_packRegisters): added an optimization while reading
1536 structure bitfields, some registers may be saved (malloc code is
1537 decreased by 80 bytes)
1539 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1541 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1542 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1543 this can be optimized more?
1545 2005-03-10 Raphael Neider <rneider AT web.de>
1547 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1548 genNearPointerGet): (hopefully) fixed access to bitfields via
1549 pointers (p->bitN = x; and x = p->bitN; failed)
1551 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1594 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1595 to keep the correct label reference count when adding/removing references
1596 to labels. A peephole file using this is appended to patch #1144962.

1728 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1729 (sizeof(sectNames) changed to sizeof(sectName))
1730 Both patches fix segfaults under MinGW.
1732 2005-01-23 Raphael Neider <rneider AT web.de>
1734 * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
1735 Safe_[mc]?alloc()'ed variables
1736 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1737 of (byte sized) temporaries (assign them to WREG for now)
1738 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1739 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1740 this might fix SIGSEGVs on MinGW...

2168 "operandsNotRelated" -- similar to "operandsNotSame", but takes
2169 architecture specific register naming into account, handles n-way
2170 comparisons, and supports quoted literals
2171 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
2173 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2181 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2183 Adding support for replacing ljmps with sjmps in jumptables
2184 generated for switch statements. For now you need to set the
2185 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2186 Now 4 algorithms for mcs51 jumptable generation are used:
2187 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2188 addresses loaded pc-relative for up to 112 cases and stack-pushing
2189 target addresses loaded with offset from dptr for up to 256 cases.
2191 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2192 * src/mcs51/main.c: adapted constants for switch table generation
2193 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2215 Large cummulative patch for pic16 port.
2216 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2217 to call when a stack overflow occurs,
2218 * (malloc.h): added CVS Id tag,
2219 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2221 * added libc directory. The current version of LibC contains string
2222 functions, ctype functions and macros and some functions of the
2223 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2224 be extensively tested in the future. Standard disclaimer here.
2225 Library is not automatically build yet. But one can build it by
2226 invoking 'make' inside the libc directory.
2227 * added ADC library under libio. Preliminary version yet.
2229 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2233 temporary registers, its a buggy feature and will be removed,
2234 * (pic16_popGet): set register instance field in AOP_CRY,
2235 * (pic16_outBitC): fixed for results in size greater than 1,
2236 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2237 * (pic16_storeForReturn): optimized return of 0,
2238 * (genCmp): experimental code for new genCmp which uses PIC18's
2239 special compare&skip instructions. Initial tests fail some times
2240 with variables grater than 1 byte in size, so new code is disabled,
2241 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2243 * (genCast): began a fix to optimize the casting of a bit to another
2244 bit, now assigning a bitfield to another bitfield will fail, sorry,
2245 * src/pic16/main.c: disabled the use of lr-support feature,
2246 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2247 * added some function prototypes, added function _debugf prototype,
2248 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2249 bits with offset (case PO_GPR_BIT),
2250 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2252 * (isBankInstruction): modified to return 0 for no banking instruction,
2253 and 1 for banking instruction,
2254 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2255 caused stop processing pCodes after a inline assembly block,
2256 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2257 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2258 registers when it shouldn't,
2259 * src/pic16/ralloc.c (allocReg): add preliminary support for
2260 supporting a limited set of temporary registers,
2262 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2264 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2265 genDataPointerSet): ensure assignments always copy in MSB to LSB
2267 (loadRegFromAop): recognize CLRH optimization,
2268 (genFunction): optimize RECEIVE iCodes in reentrant functions
2270 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2272 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2273 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2275 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2281 * device/lib/_gptrget.c (_gptrget),
2282 * device/lib/_gptrgetc.c (_gptrgetc),
2283 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2284 instead of sjmp to ret
2285 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2286 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2288 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5271 to be linked with the current source (-l arguments). Changes
5272 currently will affect only the pic16 port.
5273 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5274 include path the port specific paths and port specific libraries,
5275 * gplink command now contains the $3 argument,
5276 * src/pic16/device.h,
5277 * src/pic16/device.c,: structure PIC_device is made public and
5278 renamed to PIC16_device, the same for variable Pics which is renamed
5279 to Pics16. Updated all references to them.
5280 * src/pic16/glue.c (pic16glue): corrected bug with code
5281 initialization which bypassed the variable initializations block.
5283 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5284 COMPILE_FLAGS and added the --nostdinc option
5286 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5288 * device/include/mc68hc908jb8.h: Register defs for another member
5289 of the hc08 family. Contributed by Bjorn Bringert - thanks!
5291 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5293 Documenting changes from previous commits.
5294 * configure.in (version 1.56),
5295 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5296 when generating output files to configure the pic16 library,
5297 but now I've commented it out, since gputils aren't installed in the
5298 SF compile farm, so library won't compile
5300 * device/lib/Makefile.in (version 1.56): initially I've added in
5301 target 'all' the prerequestive 'model-pic16' so it compiled the
5302 pic16 library, but now I've commented it out for the same reasons
5304 * added targets 'model-pic16' and 'objects-pic16' to compile the
5306 * added target 'port-specific-objects-pic16' to handle the
5307 generated libraries and copy them into the build/ directory
5308 * added target 'clean-intermediate-pic16' to clean intermediate
5309 files into pic16 directory
5310 * in target 'installdirs' added line to create directory pic16 in
5311 the installation path
5313 * device/include/Makefile.in (version 1.11): in target 'install'
5314 added lines to copy all header files to installation path,
5315 * in target 'installdirs' added line create directory for pic16
5316 headers in the installation path
5318 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5331 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5332 option so that it actually works. Made it specific to the z80, since
5333 the gbz80 doesn't have these kinds of I/O ports.
5335 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5337 * device/include/z180.h,

5350 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5352 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5353 changed interrupt vector table generation to only emit declared vectors.
5354 * device/include/Makefile.in: added missing backslash
5355 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5357 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5359 Mainly changes to support compilation of the device libraries
5360 * src/pic16/device.c: stack is allocated via symbol and not
5361 via literal number. The symbol is placed in the corresponding
5362 position of the data ram
5363 * (pic16_dump_section): relocatable and absolute uninitialized
5364 data are now emitted in sorted order to reduce section naming,
5365 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5366 weren't marked as being in the access bank,
5368 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5370 Added portion of GNU PIC Library under the directory
5371 device/include/pic16 and device/lib/pic16. These files
5372 contain the declarations of SFRs for the PIC18Fxx2 devices.
5373 The directory is initialized via configure from toplevel.
5375 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5377 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5378 the spilllocations to be compared correctly
5380 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5382 * src/SDCCast.c (decorateType): fixed bug introduced today
5384 2004-01-12 Borut Razem <borut.razem AT siol.net>

5402 * doc/sdccman.lyx: Moved and added some sections, small changes
5403 all over. Telling LaTeX to be less strict with word spacing
5404 to better keep the right margin. Changed some notes about
5405 maintainance of the ports in section 3.2.1 - is it OK like this?
5407 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5444 UPPER for immediate operands,
5445 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5447 * src/pic16/peeph.def: all peepholes with movff are commented out,
5448 because there is a problem in the pcode peep optimizer,
5449 * src/pic16/ralloc.c: the register allocator can now reuse local

5451 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5453 Added file src/pic16/NOTES with information about program writing on
5454 the current port version.

5463 * src/SDCCmain.c : fixed #872250: -l command line defined library
5464 files are scanned before standard library files
5466 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5486 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5489 * src/z80/main.c: added missed needLinkerScript flags (more than
5490 one port structure defined in these file)
5491 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5507 needLinkerScript flag
5509 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5510 * src/pic/glue.c: added variable udata_section_name to
5511 override default uninitialized data segment definition for
5512 devices only with SHAREBANK memory (reported from Erik Epetrich)
5513 * (pic14emitOverlay): modified to emit a commented overlay segment
5514 directive when no overlay data exist
5515 * (picglue): modified to emit uninitialized data segment
5516 according to udata_section_name

5526 2004-01-07 Borut Razem <borut.razem AT siol.net>
5528 * support/scripts/sdcc.nsi: update PATH
5529 * support/scripts/sdcc.ico: craeted

5534 * doc/Makefile: fix install
5536 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5538 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5540 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5542 include information about variables allocated to the overlay
5545 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5547 * as/mcs51/lkmain.c: Help about -Y option

5559 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5561 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5562 (default behaviour).
5564 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5566 A python script to validate compiler diagnostic messages. It can be
5567 used to verify that sdcc complains about bad c source code and
5568 gives a good location of the error.
5569 * support/valdiag/Makefile,
5570 * support/valdiag/valdiag.py,
5571 * support/valdiag/tests/*
5573 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5586 * src/common.h: added ifndef/define/endif macros
5587 around the header file.
5588 Bug reported from Jesus Calvino-Fraga
5590 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5592 * sdcc.spec: updated
5593 * device/include/Makefile.in: don't install CVS directories
5594 * device/lib/Makefile.in: added removal of CVS directories after install
5595 * doc/Makefile: fixed install, added local_icons
5596 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5597 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5598 * src/ds390/gen.c (genRightShift): fixed bug #870788
5599 * src/SDCCast.c (decorateType): fixed bug #870781
5601 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5603 PIC16 port related changes:
5604 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5605 added variable stackPos,
5607 * gen.c: genCall, assignResultValue: added support for
5608 pushing/retrieving function parameters to/from stack,
5609 genFunction,genEndFunction: setup stack frame for the
5611 genAddrOf: will be changed according to bug 863624
5613 * added files genutils.c and genutils.h which contain gen*
5614 debugged and optimised functions extracted from gen.c
5616 * glue.c: added variable 'externs' which holds extern symbols,
5617 pic16emitRegularMap: is modified to properly handle relocatable
5618 symbols under the new scheme,
5619 pic16createInterruptVect: is modified
5620 pic16printPublics: is modified to emit 'global' assembler directives,
5621 added pic16_printExterns to print extern symbols,
5622 pic16glue: initializes stack/frame pointer in the beginning of
5623 the assembly output. Temporary hack, will be corrected later,
5624 because gplink yet does not support stack and SDCC does not
5625 yet support a type of crt0.o object to create the final binary.
5627 * Removed many lines that contain 8051 legacy code.
5628 * The code is finally placed under a 'code' directive.
5629 * Added port specific options.
5631 * _process_pragma: simplified since now we do not need *special*
5632 include file to define SFR registers. But a separate header
5633 will be needed. This will be developed later.
5634 * _pic16_parseOptions: added, parses port specific options:
5635 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5636 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5637 --preplace-udata-with=
5639 * _pic16_setDefaultOptions: modified to initialize section names,
5640 but hack is temporarly out of order since it needs improvement.
5641 * _pic16_genAssemblerPreamble: configuration words are emitted by
5642 their address instead of their name. This part is incomplete and
5643 supports only the 18Fxx2 devices. Other devices will emit an error
5644 during assembly since they do not contain the same set of config
5646 * _pic16_genIVT: is modified,
5648 * pcode.c: added definitions for some hardware registers that are needed
5650 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5651 All PCI entries are updated. Now LFSR is supported.
5652 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5653 * added pic16_newpCodeOpLit2 to support instructions with
5654 two literal arguments
5655 * pic16_pCode2str: corrected code that emits assembler instructions
5656 with two literal operands and those that have an access bit modifier
5657 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5658 this fixes a bug which caused some labels to be lost, when an
5659 assembler directive was added, i.e. banksel,
5660 * pic16_FixRegisterBanking: improved logic that causes the insertion
5662 * InlineFunction: functions that are called once, are not any more
5663 inlined. This can be a port option in the future,
5665 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5667 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5668 hold the corresponding uninitialized symbols,
5669 * pic16_allocProcessorRegister: registers have explicit marked the
5671 * pic16_allocInternalRegister: registers are explicit marked as
5673 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5674 processing list, so bit registers were lost,
5677 * ralloc.h: added field 'accessBank' and original symbol operand
5678 in register definition,
5679 * removed the field isMapped from register definition,
5681 ** Several functions have been removed from various sources:
5682 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5683 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5684 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5685 pic16_assignRelocatableRegisters
5687 ** others have been introduced:
5688 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5689 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5691 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5693 * support/scripts/inc2h.pl: changed definition of BIT_AT
5694 to emit 'sbit at' instead of 'bit at'. This was a request.
5696 PIC16 port related preliminary changes:
5697 * gen.c: prefixed function popRegFromString with
5698 pic16_ and all references to it corrected
5699 * pcode.c: all pic16_pc_* hardware registers prefixed
5700 with underscore (_),
5701 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5702 * ralloc.c: newReg(): when register is REG_SFR then
5703 set address to rIdx,
5704 pic16_allocProcessorRegister(): marks register wasUsed=0
5705 pic16_writeUsedRegs(): added a call to assign processor
5706 registers via pic16_assignFixedRegisters
5708 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5710 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5711 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5712 variables in unused register banks. Also the SSEG is placed
5713 wherever there is enough space for it, and IDATA can be anywhere
5714 in internal RAM. For now compile using -Wl-Y[stack_size].
5715 The mem file is different for this option as well, since it
5716 makes no sense of talking about DSEG lenght.
5718 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5720 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5721 in certain cases, e.g. when ROM assignment, patch provided
5722 from Albert den Haan.
5724 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6752 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6754 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6767 A few small changes that speed up the peephole optimizer.
6771 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6773 Try to make the peephole optimizer smarter by maintaining
6774 an association between the assembly source code and the
6775 iCodes that originated them. Put this information to use
6776 with a new peephole rule condition "notVolatile" so that
6777 the rules can be aggressive yet still safe.
6782 * src/mcs51/peeph.def
6784 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6788 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6789 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6790 if the left or right operand symbols have the accuse flag set.
6792 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6794 Changed the type of the result of the ! (NOT) operator to char;
6795 previously it returned the same type as the source. This allows
6796 us to eliminate all the genFloatNot functions (all of its target
6797 implementations were very buggy) since !float can use the same
6800 * src/SDCCicode.c (ast2iCode): ! returns char

6809 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6810 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6811 during interrupts. Ensure WSAVE is located at a shared bank address.
6812 2. Fixed page selection in some places
6813 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6814 the registers name strings.
6815 4. Fixed "signed / unsigned compare" compiler warnings.
6816 5. The PIC port manages its own allocation of the general purpose
6817 registers, but makes no attempt to reuse them. As a result when
6818 compiling it soon runs out of general purpose registers. Some
6819 additional code was added to the files pcode.c and device.c to walk
6820 through the function call tree and rename the registers so that they
6830 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6831 genPlus() & genMinus() when the result is the same as left or right

6837 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6839 Made bitfield a distinct type from bit so that bitfields
6840 convert as per ANSI C and bits retain their traditional
6841 boolean style behaviour. Implemented bitfield support in
6849 * src/ds390/gen.c: bit v bitfield split
6850 * src/z80/gen.c: New support for bitfields
6851 * support/regression/tests/bitfields.c: reenabled z80,
6854 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6856 Rules 246.x, 247.x relate to bitfields, the others speed up
6857 access to xdata mapped I/O devices.
6859 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6861 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6863 Cleaned up genPackBits and genUnpackBits and added two helper
6864 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6865 for literal assignments in genPackBits (thanks to Frieder for
6871 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6873 Fixed bug #748310 (pointer to function type mishandled when the
6874 function name is omitted). Also fixed a SIGSEGV when a function
6875 attribute (reentrant, etc) is used on a non-function or on a
6876 function but misplaced before the parameter list.
6878 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6880 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6903 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6905 Made the constant following the "interrupt" keyword optional. If
6906 omitted, the function will not automatically be given an entry
6907 in the interrupt vector table (similar to #pragma NOIV, but
6908 less syntacticly kludgy). The interrupt number is also now
6909 range checked. Also fixed a bug in the high order bit example

7350 condition and ignore commands.
7352 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7354 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
7355 is in parts still quite out of date, I did changes as far as I felt makes sense
7356 for a non-native english speaker.
7357 Please feel free to add to the manual or to correct my changes.
7358 * doc/Makefile: undid touching the date of intermediate tex files.
7360 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7377 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
7378 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7379 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7380 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7383 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7385 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7386 the regression tests I'm not brave enough to enable 245.b, 245.c
7387 * doc/sdccman.lyx: added latex preamble for hyperref package.
7388 Using pdflatex this will give you a hyperlinked pdf file with
7389 bookmarks. (prepend '%' before /usepackage if this breaks something)
7391 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7403 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
7405 Applied patch from bug 737905 (renamed yylineo to mylineno):
7412 * src/pic16/pcode.c: Cleaned warnings
7413 * src/pic16/pcodeflow.c: Cleaned warnings
7414 * src/pic16/pcoderegs.c: Cleaned warnings

7425 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7427 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7429 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7430 it can be defined with CFLAGS when running configure
7431 * src/SDCCmain.c: fixed compiling + linking with object files
7433 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7435 * configure.in: configure for pic16 port,
7436 added --disable-pic16-port
7437 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7438 * src/SDCCmain.c: linkOptions is changed to set *,
7439 added if/endif conditional macros to remove options help
7440 messages from optionsTable when a port is not configured, added
7441 support for the PIc16 port in the ports table, when executing
7442 the compiler with no port specified on command line, a default
7443 port is selected with the new macro DEFAULT_PORT which is
7444 defined in port.h, in setDefaultOptions() linkOptions is removed
7445 from initialization assignment, since now it is a set,
7446 parseCmdLine uses setParseWithComma for linkOptions, in
7447 linkEdit() linkOptions are accessed with new function indexSet()
7448 which returns the i'th item of a set variable. See SDCCset.c, in
7449 linkEdit() when calling buildCmdLine(), added linkOptions as
7450 last argument. Now users can pass arguments to gplink via the
7451 -Wl option, main() uses pic16glue() to glue up pic16 programs
7452 * src/SDCCpeeph.c: various changes to support pic16

7461 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7463 * src/pic16/glue.c: commented out some error producing lines
7464 * src/pic16/main.c: __config directives are commented out to stop
7465 gpasm complaining and test the linkage with gplink, _linkCmd and
7466 _asmCmd changed to be more gplink and gpasm friendly
7467 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7468 produced an error when parsed, peep rule 12 is added to utilize
7469 movff, but it is commented out since the pCode does not support
7470 yet a command with 2 address arguments
7472 2003-05-18 <johan AT balder>
7474 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7475 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7476 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

7494 on entry now. Add tbreak. Other enhancements and fixes for use
7497 2003-05-12 Borut Razem <borut.razem AT siol.net>
7499 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7501 2003-05-11 Borut Razem <borut.razem AT siol.net>
7503 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7504 the path of bin directory, so that PATH is the only env. variable, which has to be set
7505 in case of standard installation.
7506 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8535 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8537 * in \sdcc\as\mcs51\ changed these files in order to create an
8538 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8539 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8540 following files to include the previous two files: aslink.dsp,
8541 Makefile.aslink, Makefile.bcc, and Makefile.in.
8543 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8544 .adb instead of .cdb
8546 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8548 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8549 value from option --iram-size.
8551 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8553 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8556 2002-09-18 <wiml AT hhhh.org>
8558 * SDCClrange.h: exposed setFromRange() and setToRange()
8559 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8560 packRegsForAccUse() (bug 542397)
8561 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8562 multiple times and emitting the fetch operations more than once
8563 added aopGetUsesAcc() function to allow binary operators to
8564 fetch their operands in the correct order; made genMinus() emit
8565 compact code for X = LITERAL - Y
8567 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8568 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8569 sprintf() in line 1267.
8571 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8572 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8575 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8576 Changes to aslink (All the changes are marked with 'JCF'):
8578 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8581 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8582 area BSEG. Also moves, if possible, the DATA area down into the internal
8583 ram so more space is available.
8585 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8588 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8589 not bytes. Function summary() which creates a memory usage summary
8590 file with extension .mem. Reports of overlaping stack and small stack
8591 size. If the space for the stack is less than 16 bytes aslink trows a
8594 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8595 the 8051. Option 'y' for memory summary output file.
8597 Changes to sdcc (All the changes are marked with 'JCF'):
8599 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8601 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8602 overlaying area for it (uses RegBankUsed[4]).
8604 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8605 bank zero as used by default. By default aslink locates the stack
8606 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8607 the creation of the .mem file. Delegates the allocation of data area
8608 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8609 the begining of the stack area to aslink.
8611 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8612 glue() in SDCCglue.c creates an area for it.
8614 2002-09-03 Borut Razem <borut.razem AT siol.net>
8615 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8616 sdcc/src/pic/glue.c:
8617 introduced atexit() handler for teporay files removal in case of
8618 errors, assertions, ...
8620 2002-08-29 Borut Razem <borut.razem AT siol.net>
8621 * sdcc/support/cpp2/auto-host_vc_in.h:
8622 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8623 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8624 Maybe there is a similar problem with BORLANDC? It should be checked!
8626 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8627 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8628 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8629 was not executed, and the compiler (cl) launched a warning:
8630 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8632 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

8645 - added Release configuration in VS projects
8646 - review of compiler an linker options
8647 - VC .exe files are generated in bin_vc directory, not to interfere
8648 with binaries generated from other projects (cygwin, mingw, bcc ...)
8650 * sdcc/src/yacc.dsp: added
8652 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8653 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8654 and insert the version number definitions from .version
8656 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8658 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8662 removed from CVS, generated automatically
8664 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8665 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8667 2002-08-11 Borut Razem <borut.razem AT siol.net>
8668 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8670 2002-08-10 Borut Razem <borut.razem AT siol.net>
8671 * src/SDCCmain.c (main):
8672 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8673 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8674 The consequence was that some temporary files were not removed.
8677 unification of code in functions tempfilename() and tempfile():
8678 function tempnam() is defined in Visual Studio 6.0 and .NET
8680 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8682 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8683 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8684 - removed compiler command line option /WX: Treats all warnings as errors
8685 - update a list of source files, included into the project
8687 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8688 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8689 changed project type to Generic Project so that can be correcly converted to VS.NET project
8691 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8693 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

8697 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8698 added return 0 statements after assert() to make compiler happy
8700 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8701 added newline in the def file to keep MSC compiler satisfied
8703 * sdcc/src/z80/gen.c:
8704 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8705 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8706 - solved MSC error in function aopDump()
8708 * sdcc_vc.h: define PREFIX as "\\sdcc"
8710 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8766 were not getting allocated.
8768 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8771 Fixed left shift. Will promote the left side of a left shift
8772 if a) left shifting more than size of operand or b) when assigned
8773 to something size > size of left side
8775 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8885 * sdcc/src/SDCCloop.c:
8886 Previous fix was not good. basic blocks that have "break" or "return" are
8887 not really partof a loop , but live ranges used in these blocks should
8888 be live thru the entire loop, so set partOfLoop but don't add them to
8891 2002-02-21 <johan AT FRIJA>
