1364 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1365 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1366 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1367 always available in leading double underscore form. The C99 support is
1368 mostly missing, but it's a start.
1369 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1370 reserved identifier "__data".

1448 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1450 * device/lib/printf_large.c: removed inline assembly for portability and
1451 readability. Use printf_fast if speed or size are more important.
1452 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1453 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1455 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1457 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1458 prevent compiler warning
1460 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1462 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1463 moved to level 0 and declared as static. Also they are explicit
1464 placed in access bank. This was necessery because some times they
1465 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1466 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1467 optimizations. Currently only compare to unsigned char is implemented,
1468 * src/pic16/gen.c: added fReturnIdx array,
1469 * (struct resolvedIfx) is moved to gen.h and made public,
1470 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1471 * (aopForSym): added an optimization to directly store in stack of
1472 the operand of a SEND iCode,
1473 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1474 but as registers instead (AOP_REG) using the fReturnIdx array,
1475 * (pic16_freeAsmop): remove the freed register from the
1476 _G.sregsAlloc field,
1477 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1478 a compare of 'WREG',
1479 * (pic16_popGetTempRegCond): changed function prototype, now
1480 function takes also a bitVector argument v which holds the current
1481 set of registers that are allocated for stack access by aopForSym,
1482 registers allocated in aopForSym for accessing stack symbols are not
1483 any more part of the functions usedRegs field,
1484 * (genCall): some times aopOp is called for a stack variable to be
1485 send, aopForSym might perform the push, if this is true make sure
1486 that genCall doesn't push the variable twice by testing _G.resDirect,
1487 * (genFunction): changed testing for unspecified interrupt number
1488 from 256 to INTNO_UNSPEC,
1489 * modified selection scheme of frame pointer generation. Previously
1490 if function did use local registers a frame pointer was generated,
1491 now a frame pointer is generated only if function has arguments
1492 (that need PLUSW2 register access), or has stack arguments, or the
1493 compiler is not instructed to omit the frame pointer,
1494 * (genEndFunction): before restoring local registers that were saved
1495 in the function preamble, also restore the registers that *might*
1496 have been allocated for stack access,
1497 * (genRet): removed some old comments,
1498 * (genCmp, the active (RN's) version): added a call to the
1499 pic16_genCmp_special function to perform the compare with a more
1500 robust and optimized way,
1501 * (genInline): a feature has been added in inline code generation,
1502 which allows a wildcard variable substitution when writing inline
1503 assembly. Code is incomplete and experimental therefore undocumented,
1504 * (genCast): changed order of aopOp for result and right to allow
1505 aopForSym to directly load the result if possible,
1506 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1507 perform an optimized compare on some selected special occasions,
1508 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1509 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1510 generate an IVT any more,
1511 * src/pic16/main.c (pic16_optionsTable): added command line option
1513 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1514 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1516 * src/pic16/NOTES: Raphael Neider added in list of active developers
1517 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1518 jumptable_end to prevent bug #,
1519 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1520 inCond and outCond fields,
1521 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1522 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1523 turn off register spilling,
1524 * (packRegsForOneUse): synced with other ports' versions although it
1525 is not used currently,
1526 * (pic16_packRegisters): added an optimization while reading
1527 structure bitfields, some registers may be saved (malloc code is
1528 decreased by 80 bytes)
1530 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1532 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1533 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1534 this can be optimized more?
1536 2005-03-10 Raphael Neider <rneider AT web.de>
1538 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1539 genNearPointerGet): (hopefully) fixed access to bitfields via
1540 pointers (p->bitN = x; and x = p->bitN; failed)
1542 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1585 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1586 to keep the correct label reference count when adding/removing references
1587 to labels. A peephole file using this is appended to patch #1144962.

1719 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1720 (sizeof(sectNames) changed to sizeof(sectName))
1721 Both patches fix segfaults under MinGW.
1723 2005-01-23 Raphael Neider <rneider AT web.de>

1726 Safe_[mc]?alloc()'ed variables
1727 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1728 of (byte sized) temporaries (assign them to WREG for now)
1729 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1730 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1731 this might fix SIGSEGVs on MinGW...
1732 * src/SDCCopt.c (killDeadCode): restored original behaviour
1733 (volatile operands might get thrown away though)
1735 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1737 * src/pic16/gen.c: fixed bug #1106975,

1742 * added function attribute 'shadowregs' to take advantage of shadow
1744 * added function attribute 'wparam' as an alternative to the wparam

2174 Adding support for replacing ljmps with sjmps in jumptables
2175 generated for switch statements. For now you need to set the
2176 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2177 Now 4 algorithms for mcs51 jumptable generation are used:
2178 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2179 addresses loaded pc-relative for up to 112 cases and stack-pushing
2180 target addresses loaded with offset from dptr for up to 256 cases.
2182 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2183 * src/mcs51/main.c: adapted constants for switch table generation
2184 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2204 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2206 Large cummulative patch for pic16 port.
2207 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2208 to call when a stack overflow occurs,
2209 * (malloc.h): added CVS Id tag,
2210 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2212 * added libc directory. The current version of LibC contains string
2213 functions, ctype functions and macros and some functions of the
2214 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2215 be extensively tested in the future. Standard disclaimer here.
2216 Library is not automatically build yet. But one can build it by
2217 invoking 'make' inside the libc directory.
2218 * added ADC library under libio. Preliminary version yet.
2220 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2224 temporary registers, its a buggy feature and will be removed,
2225 * (pic16_popGet): set register instance field in AOP_CRY,

2227 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2228 * (pic16_storeForReturn): optimized return of 0,
2229 * (genCmp): experimental code for new genCmp which uses PIC18's
2230 special compare&skip instructions. Initial tests fail some times
2231 with variables grater than 1 byte in size, so new code is disabled,
2232 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2234 * (genCast): began a fix to optimize the casting of a bit to another
2235 bit, now assigning a bitfield to another bitfield will fail, sorry,
2236 * src/pic16/main.c: disabled the use of lr-support feature,
2237 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2238 * added some function prototypes, added function _debugf prototype,
2239 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2240 bits with offset (case PO_GPR_BIT),
2241 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2243 * (isBankInstruction): modified to return 0 for no banking instruction,
2244 and 1 for banking instruction,
2245 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2246 caused stop processing pCodes after a inline assembly block,
2247 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2248 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2249 registers when it shouldn't,
2250 * src/pic16/ralloc.c (allocReg): add preliminary support for
2251 supporting a limited set of temporary registers,
2253 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2255 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2256 genDataPointerSet): ensure assignments always copy in MSB to LSB
2258 (loadRegFromAop): recognize CLRH optimization,
2259 (genFunction): optimize RECEIVE iCodes in reentrant functions
2261 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2263 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2264 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

2275 instead of sjmp to ret
2276 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2277 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2279 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5262 to be linked with the current source (-l arguments). Changes
5263 currently will affect only the pic16 port.
5264 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5265 include path the port specific paths and port specific libraries,

5272 initialization which bypassed the variable initializations block.
5274 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5275 COMPILE_FLAGS and added the --nostdinc option
5277 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5284 Documenting changes from previous commits.
5285 * configure.in (version 1.56),
5286 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5287 when generating output files to configure the pic16 library,
5288 but now I've commented it out, since gputils aren't installed in the
5289 SF compile farm, so library won't compile
5291 * device/lib/Makefile.in (version 1.56): initially I've added in
5292 target 'all' the prerequestive 'model-pic16' so it compiled the
5293 pic16 library, but now I've commented it out for the same reasons
5295 * added targets 'model-pic16' and 'objects-pic16' to compile the
5297 * added target 'port-specific-objects-pic16' to handle the
5298 generated libraries and copy them into the build/ directory
5299 * added target 'clean-intermediate-pic16' to clean intermediate
5300 files into pic16 directory
5301 * in target 'installdirs' added line to create directory pic16 in
5302 the installation path
5304 * device/include/Makefile.in (version 1.11): in target 'install'
5305 added lines to copy all header files to installation path,
5306 * in target 'installdirs' added line create directory for pic16
5307 headers in the installation path
5309 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5322 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5323 option so that it actually works. Made it specific to the z80, since
5324 the gbz80 doesn't have these kinds of I/O ports.
5326 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5328 * device/include/z180.h,

5334 * device/lib/_strcmp.c,
5335 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5336 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5337 portmode; added deprecation warning for bank= and protmode= forms.
5338 Also, guard against buffer overflow.

5341 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5343 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5344 changed interrupt vector table generation to only emit declared vectors.
5345 * device/include/Makefile.in: added missing backslash
5346 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5350 Mainly changes to support compilation of the device libraries
5351 * src/pic16/device.c: stack is allocated via symbol and not
5352 via literal number. The symbol is placed in the corresponding
5353 position of the data ram
5354 * (pic16_dump_section): relocatable and absolute uninitialized
5355 data are now emitted in sorted order to reduce section naming,
5356 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5357 weren't marked as being in the access bank,
5359 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5361 Added portion of GNU PIC Library under the directory
5362 device/include/pic16 and device/lib/pic16. These files
5363 contain the declarations of SFRs for the PIC18Fxx2 devices.
5364 The directory is initialized via configure from toplevel.
5366 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5368 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5369 the spilllocations to be compared correctly
5371 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5373 * src/SDCCast.c (decorateType): fixed bug introduced today
5375 2004-01-12 Borut Razem <borut.razem AT siol.net>

5393 * doc/sdccman.lyx: Moved and added some sections, small changes
5394 all over. Telling LaTeX to be less strict with word spacing
5395 to better keep the right margin. Changed some notes about
5396 maintainance of the ports in section 3.2.1 - is it OK like this?
5398 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5435 UPPER for immediate operands,
5436 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5438 * src/pic16/peeph.def: all peepholes with movff are commented out,
5439 because there is a problem in the pcode peep optimizer,
5440 * src/pic16/ralloc.c: the register allocator can now reuse local
5441 function symbols for another function. This saves register usage.
5442 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5444 Added file src/pic16/NOTES with information about program writing on
5445 the current port version.

5477 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5480 * src/z80/main.c: added missed needLinkerScript flags (more than
5481 one port structure defined in these file)
5482 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5498 needLinkerScript flag
5500 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5501 * src/pic/glue.c: added variable udata_section_name to
5502 override default uninitialized data segment definition for

5504 * (pic14emitOverlay): modified to emit a commented overlay segment
5505 directive when no overlay data exist
5506 * (picglue): modified to emit uninitialized data segment
5507 according to udata_section_name

5517 2004-01-07 Borut Razem <borut.razem AT siol.net>
5519 * support/scripts/sdcc.nsi: update PATH
5520 * support/scripts/sdcc.ico: craeted

5533 include information about variables allocated to the overlay
5536 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5538 * as/mcs51/lkmain.c: Help about -Y option

5550 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5552 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5553 (default behaviour).
5555 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5557 A python script to validate compiler diagnostic messages. It can be
5558 used to verify that sdcc complains about bad c source code and
5559 gives a good location of the error.
5560 * support/valdiag/Makefile,
5561 * support/valdiag/valdiag.py,
5562 * support/valdiag/tests/*
5564 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5579 Bug reported from Jesus Calvino-Fraga
5581 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5583 * sdcc.spec: updated
5584 * device/include/Makefile.in: don't install CVS directories
5585 * device/lib/Makefile.in: added removal of CVS directories after install
5586 * doc/Makefile: fixed install, added local_icons
5587 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5588 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5589 * src/ds390/gen.c (genRightShift): fixed bug #870788
5590 * src/SDCCast.c (decorateType): fixed bug #870781
5592 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5594 PIC16 port related changes:
5595 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5596 added variable stackPos,
5598 * gen.c: genCall, assignResultValue: added support for
5599 pushing/retrieving function parameters to/from stack,
5600 genFunction,genEndFunction: setup stack frame for the
5602 genAddrOf: will be changed according to bug 863624
5604 * added files genutils.c and genutils.h which contain gen*
5605 debugged and optimised functions extracted from gen.c
5607 * glue.c: added variable 'externs' which holds extern symbols,
5608 pic16emitRegularMap: is modified to properly handle relocatable
5609 symbols under the new scheme,
5610 pic16createInterruptVect: is modified
5611 pic16printPublics: is modified to emit 'global' assembler directives,
5612 added pic16_printExterns to print extern symbols,
5613 pic16glue: initializes stack/frame pointer in the beginning of
5614 the assembly output. Temporary hack, will be corrected later,
5615 because gplink yet does not support stack and SDCC does not
5616 yet support a type of crt0.o object to create the final binary.
5618 * Removed many lines that contain 8051 legacy code.
5619 * The code is finally placed under a 'code' directive.
5620 * Added port specific options.
5622 * _process_pragma: simplified since now we do not need *special*
5623 include file to define SFR registers. But a separate header
5624 will be needed. This will be developed later.
5625 * _pic16_parseOptions: added, parses port specific options:
5626 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5627 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5628 --preplace-udata-with=
5630 * _pic16_setDefaultOptions: modified to initialize section names,
5631 but hack is temporarly out of order since it needs improvement.
5632 * _pic16_genAssemblerPreamble: configuration words are emitted by
5633 their address instead of their name. This part is incomplete and
5634 supports only the 18Fxx2 devices. Other devices will emit an error
5635 during assembly since they do not contain the same set of config
5637 * _pic16_genIVT: is modified,
5639 * pcode.c: added definitions for some hardware registers that are needed
5641 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5642 All PCI entries are updated. Now LFSR is supported.
5643 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5644 * added pic16_newpCodeOpLit2 to support instructions with
5645 two literal arguments
5646 * pic16_pCode2str: corrected code that emits assembler instructions
5647 with two literal operands and those that have an access bit modifier
5648 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5649 this fixes a bug which caused some labels to be lost, when an
5650 assembler directive was added, i.e. banksel,
5651 * pic16_FixRegisterBanking: improved logic that causes the insertion
5653 * InlineFunction: functions that are called once, are not any more
5654 inlined. This can be a port option in the future,
5656 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5658 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5659 hold the corresponding uninitialized symbols,
5660 * pic16_allocProcessorRegister: registers have explicit marked the
5662 * pic16_allocInternalRegister: registers are explicit marked as
5664 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5665 processing list, so bit registers were lost,
5668 * ralloc.h: added field 'accessBank' and original symbol operand
5669 in register definition,
5670 * removed the field isMapped from register definition,
5672 ** Several functions have been removed from various sources:
5673 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5674 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5675 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5676 pic16_assignRelocatableRegisters
5678 ** others have been introduced:
5679 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5680 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5682 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5684 * support/scripts/inc2h.pl: changed definition of BIT_AT
5685 to emit 'sbit at' instead of 'bit at'. This was a request.
5687 PIC16 port related preliminary changes:
5688 * gen.c: prefixed function popRegFromString with
5689 pic16_ and all references to it corrected
5690 * pcode.c: all pic16_pc_* hardware registers prefixed
5691 with underscore (_),
5692 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5693 * ralloc.c: newReg(): when register is REG_SFR then
5694 set address to rIdx,
5695 pic16_allocProcessorRegister(): marks register wasUsed=0
5696 pic16_writeUsedRegs(): added a call to assign processor
5697 registers via pic16_assignFixedRegisters
5699 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5701 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5702 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5703 variables in unused register banks. Also the SSEG is placed
5704 wherever there is enough space for it, and IDATA can be anywhere
5705 in internal RAM. For now compile using -Wl-Y[stack_size].
5706 The mem file is different for this option as well, since it
5707 makes no sense of talking about DSEG lenght.
5709 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5711 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5712 in certain cases, e.g. when ROM assignment, patch provided
5713 from Albert den Haan.
5715 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6758 A few small changes that speed up the peephole optimizer.
6762 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6764 Try to make the peephole optimizer smarter by maintaining
6765 an association between the assembly source code and the
6766 iCodes that originated them. Put this information to use
6767 with a new peephole rule condition "notVolatile" so that
6768 the rules can be aggressive yet still safe.
6773 * src/mcs51/peeph.def
6775 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6779 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6780 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6781 if the left or right operand symbols have the accuse flag set.
6783 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6785 Changed the type of the result of the ! (NOT) operator to char;
6786 previously it returned the same type as the source. This allows
6787 us to eliminate all the genFloatNot functions (all of its target
6788 implementations were very buggy) since !float can use the same
6791 * src/SDCCicode.c (ast2iCode): ! returns char
6792 * src/mcs51/gen.c (genNot, genNotFloat),
6793 * src/ds390/gen.c (genNot, genNotFloat),
6794 * src/z80/gen.c (genNot, genNotFloat),
6795 * src/pic/gen.c (genNot, genNotFloat),
6796 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6800 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6801 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6802 during interrupts. Ensure WSAVE is located at a shared bank address.
6803 2. Fixed page selection in some places
6804 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6805 the registers name strings.
6806 4. Fixed "signed / unsigned compare" compiler warnings.
6807 5. The PIC port manages its own allocation of the general purpose
6808 registers, but makes no attempt to reuse them. As a result when
6809 compiling it soon runs out of general purpose registers. Some
6810 additional code was added to the files pcode.c and device.c to walk
6811 through the function call tree and rename the registers so that they
6821 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6822 genPlus() & genMinus() when the result is the same as left or right
6824 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6828 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6830 Made bitfield a distinct type from bit so that bitfields
6831 convert as per ANSI C and bits retain their traditional
6832 boolean style behaviour. Implemented bitfield support in
6840 * src/ds390/gen.c: bit v bitfield split
6841 * src/z80/gen.c: New support for bitfields
6842 * support/regression/tests/bitfields.c: reenabled z80,
6845 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6847 Rules 246.x, 247.x relate to bitfields, the others speed up
6848 access to xdata mapped I/O devices.
6850 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6852 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6854 Cleaned up genPackBits and genUnpackBits and added two helper
6855 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6856 for literal assignments in genPackBits (thanks to Frieder for
6862 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6864 Fixed bug #748310 (pointer to function type mishandled when the
6865 function name is omitted). Also fixed a SIGSEGV when a function
6866 attribute (reentrant, etc) is used on a non-function or on a
6867 function but misplaced before the parameter list.
6869 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6871 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6872 * support/Util/SDCCerr.h,

6894 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6896 Made the constant following the "interrupt" keyword optional. If
6897 omitted, the function will not automatically be given an entry
6898 in the interrupt vector table (similar to #pragma NOIV, but
6899 less syntacticly kludgy). The interrupt number is also now
6900 range checked. Also fixed a bug in the high order bit example

6916 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6918 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6919 be re-activated by defining REDUCE_LITERALS)
6920 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6921 unsigned, but are signed by default
6922 * src/SDCCval.c (constVal): rearranged
6923 * src/SDCCval.c (valMod): preliminary fix
6924 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7361 * device/lib/gbz80/stubs.s
7362 * device/lib/z80/mul.s
7363 * device/lib/z80/stubs.s
7364 * src/SDCCsymt.c (initCSupport)
7366 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7368 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
7369 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7370 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7371 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7374 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7376 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7377 the regression tests I'm not brave enough to enable 245.b, 245.c
7378 * doc/sdccman.lyx: added latex preamble for hyperref package.
7379 Using pdflatex this will give you a hyperlinked pdf file with
7380 bookmarks. (prepend '%' before /usepackage if this breaks something)
7382 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7392 * src/SDCCglue.c (printIval): fixed bug #739934
7394 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
7396 Applied patch from bug 737905 (renamed yylineo to mylineno):
7403 * src/pic16/pcode.c: Cleaned warnings
7404 * src/pic16/pcodeflow.c: Cleaned warnings
7405 * src/pic16/pcoderegs.c: Cleaned warnings

7418 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7420 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7421 it can be defined with CFLAGS when running configure
7422 * src/SDCCmain.c: fixed compiling + linking with object files
7424 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7426 * configure.in: configure for pic16 port,
7427 added --disable-pic16-port
7428 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7429 * src/SDCCmain.c: linkOptions is changed to set *,
7430 added if/endif conditional macros to remove options help
7431 messages from optionsTable when a port is not configured, added
7432 support for the PIc16 port in the ports table, when executing
7433 the compiler with no port specified on command line, a default
7434 port is selected with the new macro DEFAULT_PORT which is
7435 defined in port.h, in setDefaultOptions() linkOptions is removed
7436 from initialization assignment, since now it is a set,
7437 parseCmdLine uses setParseWithComma for linkOptions, in
7438 linkEdit() linkOptions are accessed with new function indexSet()
7439 which returns the i'th item of a set variable. See SDCCset.c, in
7440 linkEdit() when calling buildCmdLine(), added linkOptions as
7441 last argument. Now users can pass arguments to gplink via the
7442 -Wl option, main() uses pic16glue() to glue up pic16 programs
7443 * src/SDCCpeeph.c: various changes to support pic16
7444 * src/SDCCset.c: added function void *indexSet(set *, int) to

7454 * src/pic16/glue.c: commented out some error producing lines
7455 * src/pic16/main.c: __config directives are commented out to stop
7456 gpasm complaining and test the linkage with gplink, _linkCmd and
7457 _asmCmd changed to be more gplink and gpasm friendly
7458 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7459 produced an error when parsed, peep rule 12 is added to utilize
7460 movff, but it is commented out since the pCode does not support
7461 yet a command with 2 address arguments
7463 2003-05-18 <johan AT balder>
7465 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7466 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7467 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

7490 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7492 2003-05-11 Borut Razem <borut.razem AT siol.net>
7494 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7495 the path of bin directory, so that PATH is the only env. variable, which has to be set
7496 in case of standard installation.
7497 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8500 * src/SDCCicode.c: fixed array add
8502 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8503 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8504 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8506 2003-01-04 <johan AT balder>
8508 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8510 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8511 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8513 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8514 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8523 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8524 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8526 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8528 * in \sdcc\as\mcs51\ changed these files in order to create an
8529 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8530 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8531 following files to include the previous two files: aslink.dsp,
8532 Makefile.aslink, Makefile.bcc, and Makefile.in.
8534 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8535 .adb instead of .cdb
8537 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8539 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8540 value from option --iram-size.
8542 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8544 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8547 2002-09-18 <wiml AT hhhh.org>
8549 * SDCClrange.h: exposed setFromRange() and setToRange()
8550 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8551 packRegsForAccUse() (bug 542397)
8552 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8553 multiple times and emitting the fetch operations more than once
8554 added aopGetUsesAcc() function to allow binary operators to
8555 fetch their operands in the correct order; made genMinus() emit
8556 compact code for X = LITERAL - Y
8558 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8559 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8560 sprintf() in line 1267.
8562 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8563 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8566 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8567 Changes to aslink (All the changes are marked with 'JCF'):
8569 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8572 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8573 area BSEG. Also moves, if possible, the DATA area down into the internal
8574 ram so more space is available.
8576 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8579 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8580 not bytes. Function summary() which creates a memory usage summary
8581 file with extension .mem. Reports of overlaping stack and small stack
8582 size. If the space for the stack is less than 16 bytes aslink trows a
8585 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8586 the 8051. Option 'y' for memory summary output file.
8588 Changes to sdcc (All the changes are marked with 'JCF'):
8590 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8592 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8593 overlaying area for it (uses RegBankUsed[4]).
8595 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8596 bank zero as used by default. By default aslink locates the stack
8597 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8598 the creation of the .mem file. Delegates the allocation of data area
8599 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8600 the begining of the stack area to aslink.
8602 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8603 glue() in SDCCglue.c creates an area for it.
8605 2002-09-03 Borut Razem <borut.razem AT siol.net>
8606 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8607 sdcc/src/pic/glue.c:
8608 introduced atexit() handler for teporay files removal in case of
8609 errors, assertions, ...
8611 2002-08-29 Borut Razem <borut.razem AT siol.net>
8612 * sdcc/support/cpp2/auto-host_vc_in.h:
8613 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8614 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8615 Maybe there is a similar problem with BORLANDC? It should be checked!
8617 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8618 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8619 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8620 was not executed, and the compiler (cl) launched a warning:
8621 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8623 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8624 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8626 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8627 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8629 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8630 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8631 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8632 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8633 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8634 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8635 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8636 - added Release configuration in VS projects
8637 - review of compiler an linker options
8638 - VC .exe files are generated in bin_vc directory, not to interfere
8639 with binaries generated from other projects (cygwin, mingw, bcc ...)
8641 * sdcc/src/yacc.dsp: added
8643 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8644 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8645 and insert the version number definitions from .version
8647 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8649 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8650 added - genarate auto-host.h using auto-host_vc_in.h as template
8653 removed from CVS, generated automatically
8655 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8656 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8658 2002-08-11 Borut Razem <borut.razem AT siol.net>
8659 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8661 2002-08-10 Borut Razem <borut.razem AT siol.net>
8662 * src/SDCCmain.c (main):
8663 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8664 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8665 The consequence was that some temporary files were not removed.
8668 unification of code in functions tempfilename() and tempfile():
8669 function tempnam() is defined in Visual Studio 6.0 and .NET
8671 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8673 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8674 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8675 - removed compiler command line option /WX: Treats all warnings as errors
8676 - update a list of source files, included into the project
8678 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

8689 added return 0 statements after assert() to make compiler happy
8691 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8692 added newline in the def file to keep MSC compiler satisfied
8694 * sdcc/src/z80/gen.c:
8695 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8696 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8697 - solved MSC error in function aopDump()
8699 * sdcc_vc.h: define PREFIX as "\\sdcc"

8876 * sdcc/src/SDCCloop.c:
8877 Previous fix was not good. basic blocks that have "break" or "return" are
8878 not really partof a loop , but live ranges used in these blocks should
8879 be live thru the entire loop, so set partOfLoop but don't add them to
