1351 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1353 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1354 * src/z80/main.c (_keywords[]),
1355 * src/SDCCglobal.h (struct options),
1357 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1358 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1359 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1360 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1361 always available in leading double underscore form. The C99 support is
1362 mostly missing, but it's a start.
1363 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1364 reserved identifier "__data".
1366 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1410 immedDom() returning wrong block; probably fixes bug #1160833)
1412 2005-03-20 Borut Razem <borut.razem AT siol.net>
1414 * support/scripts/inc2h.pl: WIN32 port

1420 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1422 * device/include/stdint.h: added
1423 * device/lib/abs.c: added

1442 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1444 * device/lib/printf_large.c: removed inline assembly for portability and
1445 readability. Use printf_fast if speed or size are more important.
1446 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1447 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1449 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1451 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1452 prevent compiler warning
1454 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1456 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1457 moved to level 0 and declared as static. Also they are explicit
1458 placed in access bank. This was necessery because some times they
1459 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1460 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1461 optimizations. Currently only compare to unsigned char is implemented,
1462 * src/pic16/gen.c: added fReturnIdx array,
1463 * (struct resolvedIfx) is moved to gen.h and made public,
1464 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1465 * (aopForSym): added an optimization to directly store in stack of
1466 the operand of a SEND iCode,
1467 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1468 but as registers instead (AOP_REG) using the fReturnIdx array,
1469 * (pic16_freeAsmop): remove the freed register from the
1470 _G.sregsAlloc field,
1471 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1472 a compare of 'WREG',
1473 * (pic16_popGetTempRegCond): changed function prototype, now
1474 function takes also a bitVector argument v which holds the current
1475 set of registers that are allocated for stack access by aopForSym,
1476 registers allocated in aopForSym for accessing stack symbols are not
1477 any more part of the functions usedRegs field,
1478 * (genCall): some times aopOp is called for a stack variable to be
1479 send, aopForSym might perform the push, if this is true make sure
1480 that genCall doesn't push the variable twice by testing _G.resDirect,
1481 * (genFunction): changed testing for unspecified interrupt number
1482 from 256 to INTNO_UNSPEC,
1483 * modified selection scheme of frame pointer generation. Previously
1484 if function did use local registers a frame pointer was generated,
1485 now a frame pointer is generated only if function has arguments
1486 (that need PLUSW2 register access), or has stack arguments, or the
1487 compiler is not instructed to omit the frame pointer,
1488 * (genEndFunction): before restoring local registers that were saved
1489 in the function preamble, also restore the registers that *might*
1490 have been allocated for stack access,
1491 * (genRet): removed some old comments,
1492 * (genCmp, the active (RN's) version): added a call to the
1493 pic16_genCmp_special function to perform the compare with a more
1494 robust and optimized way,
1495 * (genInline): a feature has been added in inline code generation,
1496 which allows a wildcard variable substitution when writing inline
1497 assembly. Code is incomplete and experimental therefore undocumented,
1498 * (genCast): changed order of aopOp for result and right to allow
1499 aopForSym to directly load the result if possible,
1500 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1501 perform an optimized compare on some selected special occasions,
1502 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1503 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1504 generate an IVT any more,
1505 * src/pic16/main.c (pic16_optionsTable): added command line option
1507 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1508 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1510 * src/pic16/NOTES: Raphael Neider added in list of active developers
1511 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1512 jumptable_end to prevent bug #,
1513 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1514 inCond and outCond fields,
1515 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1516 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1517 turn off register spilling,
1518 * (packRegsForOneUse): synced with other ports' versions although it
1519 is not used currently,
1520 * (pic16_packRegisters): added an optimization while reading
1521 structure bitfields, some registers may be saved (malloc code is
1522 decreased by 80 bytes)
1524 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1526 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1527 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1528 this can be optimized more?
1530 2005-03-10 Raphael Neider <rneider AT web.de>
1532 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1533 genNearPointerGet): (hopefully) fixed access to bitfields via
1534 pointers (p->bitN = x; and x = p->bitN; failed)
1536 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1538 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1579 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1580 to keep the correct label reference count when adding/removing references
1581 to labels. A peephole file using this is appended to patch #1144962.
1583 2005-02-14 Raphael Neider <rneider AT web.de>

1713 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1714 (sizeof(sectNames) changed to sizeof(sectName))
1715 Both patches fix segfaults under MinGW.
1717 2005-01-23 Raphael Neider <rneider AT web.de>

1720 Safe_[mc]?alloc()'ed variables
1721 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1722 of (byte sized) temporaries (assign them to WREG for now)
1723 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1724 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1725 this might fix SIGSEGVs on MinGW...
1726 * src/SDCCopt.c (killDeadCode): restored original behaviour
1727 (volatile operands might get thrown away though)
1729 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1731 * src/pic16/gen.c: fixed bug #1106975,

1736 * added function attribute 'shadowregs' to take advantage of shadow
1738 * added function attribute 'wparam' as an alternative to the wparam
1740 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
1741 user declares a non-ISR function as 'shadowregs',
1742 * doc/sdccman.lyx: updated to reflect recent changes of pic16 port

2171 Now 4 algorithms for mcs51 jumptable generation are used:
2172 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2173 addresses loaded pc-relative for up to 112 cases and stack-pushing
2174 target addresses loaded with offset from dptr for up to 256 cases.
2176 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2177 * src/mcs51/main.c: adapted constants for switch table generation
2178 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2198 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2200 Large cummulative patch for pic16 port.
2201 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2202 to call when a stack overflow occurs,
2203 * (malloc.h): added CVS Id tag,
2204 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2206 * added libc directory. The current version of LibC contains string
2207 functions, ctype functions and macros and some functions of the
2208 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2209 be extensively tested in the future. Standard disclaimer here.
2210 Library is not automatically build yet. But one can build it by
2211 invoking 'make' inside the libc directory.
2212 * added ADC library under libio. Preliminary version yet.
2214 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2215 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2216 aopForRemat() now and not by pic16_aopOp(),
2217 * (pic16_popGetTempReg): removed warning messgae when allocating
2218 temporary registers, its a buggy feature and will be removed,
2219 * (pic16_popGet): set register instance field in AOP_CRY,
2220 * (pic16_outBitC): fixed for results in size greater than 1,
2221 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2222 * (pic16_storeForReturn): optimized return of 0,
2223 * (genCmp): experimental code for new genCmp which uses PIC18's
2224 special compare&skip instructions. Initial tests fail some times
2225 with variables grater than 1 byte in size, so new code is disabled,
2226 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2228 * (genCast): began a fix to optimize the casting of a bit to another
2229 bit, now assigning a bitfield to another bitfield will fail, sorry,
2230 * src/pic16/main.c: disabled the use of lr-support feature,
2231 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2232 * added some function prototypes, added function _debugf prototype,
2233 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2234 bits with offset (case PO_GPR_BIT),
2235 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2237 * (isBankInstruction): modified to return 0 for no banking instruction,
2238 and 1 for banking instruction,
2239 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2240 caused stop processing pCodes after a inline assembly block,
2241 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2242 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2243 registers when it shouldn't,
2244 * src/pic16/ralloc.c (allocReg): add preliminary support for
2245 supporting a limited set of temporary registers,
2247 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2249 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2250 genDataPointerSet): ensure assignments always copy in MSB to LSB
2252 (loadRegFromAop): recognize CLRH optimization,
2253 (genFunction): optimize RECEIVE iCodes in reentrant functions
2255 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2257 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2258 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2260 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2271 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2273 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5255 loaded with the linker search paths (-L arguments) and the libraries
5256 to be linked with the current source (-l arguments). Changes
5257 currently will affect only the pic16 port.
5258 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5259 include path the port specific paths and port specific libraries,

5278 Documenting changes from previous commits.
5279 * configure.in (version 1.56),
5280 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5281 when generating output files to configure the pic16 library,
5282 but now I've commented it out, since gputils aren't installed in the
5283 SF compile farm, so library won't compile
5285 * device/lib/Makefile.in (version 1.56): initially I've added in
5286 target 'all' the prerequestive 'model-pic16' so it compiled the
5287 pic16 library, but now I've commented it out for the same reasons
5289 * added targets 'model-pic16' and 'objects-pic16' to compile the
5291 * added target 'port-specific-objects-pic16' to handle the
5292 generated libraries and copy them into the build/ directory
5293 * added target 'clean-intermediate-pic16' to clean intermediate
5294 files into pic16 directory
5295 * in target 'installdirs' added line to create directory pic16 in
5296 the installation path
5298 * device/include/Makefile.in (version 1.11): in target 'install'
5299 added lines to copy all header files to installation path,
5300 * in target 'installdirs' added line create directory for pic16
5301 headers in the installation path
5303 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5316 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5317 option so that it actually works. Made it specific to the z80, since
5318 the gbz80 doesn't have these kinds of I/O ports.
5320 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5322 * device/include/z180.h,

5328 * device/lib/_strcmp.c,
5329 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5330 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5331 portmode; added deprecation warning for bank= and protmode= forms.
5332 Also, guard against buffer overflow.
5333 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5335 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5337 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5338 changed interrupt vector table generation to only emit declared vectors.
5339 * device/include/Makefile.in: added missing backslash
5340 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5344 Mainly changes to support compilation of the device libraries
5345 * src/pic16/device.c: stack is allocated via symbol and not
5346 via literal number. The symbol is placed in the corresponding
5347 position of the data ram
5348 * (pic16_dump_section): relocatable and absolute uninitialized
5349 data are now emitted in sorted order to reduce section naming,
5350 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5351 weren't marked as being in the access bank,
5353 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5355 Added portion of GNU PIC Library under the directory
5356 device/include/pic16 and device/lib/pic16. These files
5357 contain the declarations of SFRs for the PIC18Fxx2 devices.
5358 The directory is initialized via configure from toplevel.
5360 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5362 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5363 the spilllocations to be compared correctly
5365 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5367 * src/SDCCast.c (decorateType): fixed bug introduced today
5369 2004-01-12 Borut Razem <borut.razem AT siol.net>

5387 * doc/sdccman.lyx: Moved and added some sections, small changes
5388 all over. Telling LaTeX to be less strict with word spacing
5389 to better keep the right margin. Changed some notes about
5390 maintainance of the ports in section 3.2.1 - is it OK like this?
5392 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5394 SDCC source changes:
5395 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5429 UPPER for immediate operands,
5430 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5432 * src/pic16/peeph.def: all peepholes with movff are commented out,
5433 because there is a problem in the pcode peep optimizer,
5434 * src/pic16/ralloc.c: the register allocator can now reuse local
5435 function symbols for another function. This saves register usage.
5436 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5438 Added file src/pic16/NOTES with information about program writing on
5439 the current port version.

5471 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5474 * src/z80/main.c: added missed needLinkerScript flags (more than
5475 one port structure defined in these file)
5476 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5492 needLinkerScript flag
5494 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5495 * src/pic/glue.c: added variable udata_section_name to
5496 override default uninitialized data segment definition for
5497 devices only with SHAREBANK memory (reported from Erik Epetrich)
5498 * (pic14emitOverlay): modified to emit a commented overlay segment
5499 directive when no overlay data exist
5500 * (picglue): modified to emit uninitialized data segment
5501 according to udata_section_name

5511 2004-01-07 Borut Razem <borut.razem AT siol.net>
5513 * support/scripts/sdcc.nsi: update PATH
5514 * support/scripts/sdcc.ico: craeted

5527 include information about variables allocated to the overlay
5530 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5532 * as/mcs51/lkmain.c: Help about -Y option

5544 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5546 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5547 (default behaviour).
5549 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5551 A python script to validate compiler diagnostic messages. It can be
5552 used to verify that sdcc complains about bad c source code and
5553 gives a good location of the error.
5554 * support/valdiag/Makefile,
5555 * support/valdiag/valdiag.py,
5556 * support/valdiag/tests/*

5573 Bug reported from Jesus Calvino-Fraga
5575 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5577 * sdcc.spec: updated
5578 * device/include/Makefile.in: don't install CVS directories
5579 * device/lib/Makefile.in: added removal of CVS directories after install
5580 * doc/Makefile: fixed install, added local_icons
5581 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5582 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5583 * src/ds390/gen.c (genRightShift): fixed bug #870788
5584 * src/SDCCast.c (decorateType): fixed bug #870781
5586 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5588 PIC16 port related changes:
5589 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5590 added variable stackPos,
5592 * gen.c: genCall, assignResultValue: added support for
5593 pushing/retrieving function parameters to/from stack,
5594 genFunction,genEndFunction: setup stack frame for the
5596 genAddrOf: will be changed according to bug 863624
5598 * added files genutils.c and genutils.h which contain gen*
5599 debugged and optimised functions extracted from gen.c
5601 * glue.c: added variable 'externs' which holds extern symbols,
5602 pic16emitRegularMap: is modified to properly handle relocatable
5603 symbols under the new scheme,
5604 pic16createInterruptVect: is modified
5605 pic16printPublics: is modified to emit 'global' assembler directives,
5606 added pic16_printExterns to print extern symbols,
5607 pic16glue: initializes stack/frame pointer in the beginning of
5608 the assembly output. Temporary hack, will be corrected later,
5609 because gplink yet does not support stack and SDCC does not
5610 yet support a type of crt0.o object to create the final binary.
5612 * Removed many lines that contain 8051 legacy code.
5613 * The code is finally placed under a 'code' directive.
5614 * Added port specific options.
5616 * _process_pragma: simplified since now we do not need *special*
5617 include file to define SFR registers. But a separate header
5618 will be needed. This will be developed later.
5619 * _pic16_parseOptions: added, parses port specific options:
5620 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5621 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5622 --preplace-udata-with=
5624 * _pic16_setDefaultOptions: modified to initialize section names,
5625 but hack is temporarly out of order since it needs improvement.
5626 * _pic16_genAssemblerPreamble: configuration words are emitted by
5627 their address instead of their name. This part is incomplete and
5628 supports only the 18Fxx2 devices. Other devices will emit an error
5629 during assembly since they do not contain the same set of config
5631 * _pic16_genIVT: is modified,
5633 * pcode.c: added definitions for some hardware registers that are needed
5635 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5636 All PCI entries are updated. Now LFSR is supported.
5637 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5638 * added pic16_newpCodeOpLit2 to support instructions with
5639 two literal arguments
5640 * pic16_pCode2str: corrected code that emits assembler instructions
5641 with two literal operands and those that have an access bit modifier
5642 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5643 this fixes a bug which caused some labels to be lost, when an
5644 assembler directive was added, i.e. banksel,
5645 * pic16_FixRegisterBanking: improved logic that causes the insertion
5647 * InlineFunction: functions that are called once, are not any more
5648 inlined. This can be a port option in the future,
5650 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5652 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5653 hold the corresponding uninitialized symbols,
5654 * pic16_allocProcessorRegister: registers have explicit marked the
5656 * pic16_allocInternalRegister: registers are explicit marked as
5658 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5659 processing list, so bit registers were lost,
5662 * ralloc.h: added field 'accessBank' and original symbol operand
5663 in register definition,
5664 * removed the field isMapped from register definition,
5666 ** Several functions have been removed from various sources:
5667 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5668 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5669 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5670 pic16_assignRelocatableRegisters
5672 ** others have been introduced:
5673 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5674 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5676 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5678 * support/scripts/inc2h.pl: changed definition of BIT_AT
5679 to emit 'sbit at' instead of 'bit at'. This was a request.
5681 PIC16 port related preliminary changes:
5682 * gen.c: prefixed function popRegFromString with
5683 pic16_ and all references to it corrected
5684 * pcode.c: all pic16_pc_* hardware registers prefixed
5685 with underscore (_),
5686 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5687 * ralloc.c: newReg(): when register is REG_SFR then
5688 set address to rIdx,
5689 pic16_allocProcessorRegister(): marks register wasUsed=0
5690 pic16_writeUsedRegs(): added a call to assign processor
5691 registers via pic16_assignFixedRegisters
5693 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5695 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5696 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5697 variables in unused register banks. Also the SSEG is placed
5698 wherever there is enough space for it, and IDATA can be anywhere
5699 in internal RAM. For now compile using -Wl-Y[stack_size].
5700 The mem file is different for this option as well, since it
5701 makes no sense of talking about DSEG lenght.
5703 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5705 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5706 in certain cases, e.g. when ROM assignment, patch provided
5707 from Albert den Haan.
5709 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6760 iCodes that originated them. Put this information to use
6761 with a new peephole rule condition "notVolatile" so that
6762 the rules can be aggressive yet still safe.
6767 * src/mcs51/peeph.def
6769 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6773 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6774 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6775 if the left or right operand symbols have the accuse flag set.
6777 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6779 Changed the type of the result of the ! (NOT) operator to char;
6780 previously it returned the same type as the source. This allows
6781 us to eliminate all the genFloatNot functions (all of its target
6782 implementations were very buggy) since !float can use the same
6785 * src/SDCCicode.c (ast2iCode): ! returns char

6794 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6795 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6796 during interrupts. Ensure WSAVE is located at a shared bank address.
6797 2. Fixed page selection in some places
6798 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6799 the registers name strings.
6800 4. Fixed "signed / unsigned compare" compiler warnings.
6801 5. The PIC port manages its own allocation of the general purpose
6802 registers, but makes no attempt to reuse them. As a result when
6803 compiling it soon runs out of general purpose registers. Some
6804 additional code was added to the files pcode.c and device.c to walk
6805 through the function call tree and rename the registers so that they
6815 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6822 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6824 Made bitfield a distinct type from bit so that bitfields
6825 convert as per ANSI C and bits retain their traditional
6826 boolean style behaviour. Implemented bitfield support in
6834 * src/ds390/gen.c: bit v bitfield split
6835 * src/z80/gen.c: New support for bitfields

6839 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6841 Rules 246.x, 247.x relate to bitfields, the others speed up
6842 access to xdata mapped I/O devices.
6844 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6846 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6848 Cleaned up genPackBits and genUnpackBits and added two helper
6849 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6850 for literal assignments in genPackBits (thanks to Frieder for
6856 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6858 Fixed bug #748310 (pointer to function type mishandled when the
6859 function name is omitted). Also fixed a SIGSEGV when a function
6860 attribute (reentrant, etc) is used on a non-function or on a
6861 function but misplaced before the parameter list.

6888 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6890 Made the constant following the "interrupt" keyword optional. If
6891 omitted, the function will not automatically be given an entry
6892 in the interrupt vector table (similar to #pragma NOIV, but
6893 less syntacticly kludgy). The interrupt number is also now
6894 range checked. Also fixed a bug in the high order bit example

7354 * device/lib/gbz80/mul.s
7355 * device/lib/gbz80/stubs.s
7356 * device/lib/z80/mul.s
7357 * device/lib/z80/stubs.s
7358 * src/SDCCsymt.c (initCSupport)
7360 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7362 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
7363 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7364 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7365 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7368 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7370 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7371 the regression tests I'm not brave enough to enable 245.b, 245.c
7372 * doc/sdccman.lyx: added latex preamble for hyperref package.
7373 Using pdflatex this will give you a hyperlinked pdf file with
7374 bookmarks. (prepend '%' before /usepackage if this breaks something)
7376 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7386 * src/SDCCglue.c (printIval): fixed bug #739934
7388 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
7390 Applied patch from bug 737905 (renamed yylineo to mylineno):
7397 * src/pic16/pcode.c: Cleaned warnings
7398 * src/pic16/pcodeflow.c: Cleaned warnings
7399 * src/pic16/pcoderegs.c: Cleaned warnings
7401 2003-05-19 Scott Dattalo <scott AT dattalo.com>

7410 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7412 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7414 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7415 it can be defined with CFLAGS when running configure
7416 * src/SDCCmain.c: fixed compiling + linking with object files
7418 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7420 * configure.in: configure for pic16 port,
7421 added --disable-pic16-port
7422 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7423 * src/SDCCmain.c: linkOptions is changed to set *,
7424 added if/endif conditional macros to remove options help
7425 messages from optionsTable when a port is not configured, added
7426 support for the PIc16 port in the ports table, when executing
7427 the compiler with no port specified on command line, a default
7428 port is selected with the new macro DEFAULT_PORT which is
7429 defined in port.h, in setDefaultOptions() linkOptions is removed
7430 from initialization assignment, since now it is a set,
7431 parseCmdLine uses setParseWithComma for linkOptions, in
7432 linkEdit() linkOptions are accessed with new function indexSet()
7433 which returns the i'th item of a set variable. See SDCCset.c, in
7434 linkEdit() when calling buildCmdLine(), added linkOptions as
7435 last argument. Now users can pass arguments to gplink via the
7436 -Wl option, main() uses pic16glue() to glue up pic16 programs
7437 * src/SDCCpeeph.c: various changes to support pic16
7438 * src/SDCCset.c: added function void *indexSet(set *, int) to

7446 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7448 * src/pic16/glue.c: commented out some error producing lines
7449 * src/pic16/main.c: __config directives are commented out to stop
7450 gpasm complaining and test the linkage with gplink, _linkCmd and
7451 _asmCmd changed to be more gplink and gpasm friendly
7452 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7453 produced an error when parsed, peep rule 12 is added to utilize
7454 movff, but it is commented out since the pCode does not support
7455 yet a command with 2 address arguments
7457 2003-05-18 <johan AT balder>
7459 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7460 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7461 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

7484 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7486 2003-05-11 Borut Razem <borut.razem AT siol.net>
7488 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7489 the path of bin directory, so that PATH is the only env. variable, which has to be set
7490 in case of standard installation.
7491 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8494 * src/SDCCicode.c: fixed array add
8496 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8497 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8498 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8500 2003-01-04 <johan AT balder>
8502 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8504 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8505 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8507 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8508 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8515 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8517 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8518 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8520 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8522 * in \sdcc\as\mcs51\ changed these files in order to create an
8523 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8524 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8525 following files to include the previous two files: aslink.dsp,
8526 Makefile.aslink, Makefile.bcc, and Makefile.in.
8528 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8529 .adb instead of .cdb
8531 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8533 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8534 value from option --iram-size.
8536 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8538 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8541 2002-09-18 <wiml AT hhhh.org>
8543 * SDCClrange.h: exposed setFromRange() and setToRange()
8544 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8545 packRegsForAccUse() (bug 542397)
8546 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8547 multiple times and emitting the fetch operations more than once
8548 added aopGetUsesAcc() function to allow binary operators to
8549 fetch their operands in the correct order; made genMinus() emit
8550 compact code for X = LITERAL - Y
8552 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8553 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8554 sprintf() in line 1267.
8556 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8557 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8560 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8561 Changes to aslink (All the changes are marked with 'JCF'):
8563 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8566 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8567 area BSEG. Also moves, if possible, the DATA area down into the internal
8568 ram so more space is available.
8570 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8573 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8574 not bytes. Function summary() which creates a memory usage summary
8575 file with extension .mem. Reports of overlaping stack and small stack
8576 size. If the space for the stack is less than 16 bytes aslink trows a
8579 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8580 the 8051. Option 'y' for memory summary output file.
8582 Changes to sdcc (All the changes are marked with 'JCF'):
8584 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8586 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8587 overlaying area for it (uses RegBankUsed[4]).
8589 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8590 bank zero as used by default. By default aslink locates the stack
8591 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8592 the creation of the .mem file. Delegates the allocation of data area
8593 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8594 the begining of the stack area to aslink.
8596 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8597 glue() in SDCCglue.c creates an area for it.
8599 2002-09-03 Borut Razem <borut.razem AT siol.net>
8600 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8601 sdcc/src/pic/glue.c:
8602 introduced atexit() handler for teporay files removal in case of
8603 errors, assertions, ...
8605 2002-08-29 Borut Razem <borut.razem AT siol.net>
8606 * sdcc/support/cpp2/auto-host_vc_in.h:
8607 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8608 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8609 Maybe there is a similar problem with BORLANDC? It should be checked!
8611 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8612 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8613 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8614 was not executed, and the compiler (cl) launched a warning:
8615 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8617 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8618 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8620 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8621 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8623 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8624 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8625 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8626 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8627 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8628 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8629 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8630 - added Release configuration in VS projects
8631 - review of compiler an linker options
8632 - VC .exe files are generated in bin_vc directory, not to interfere
8633 with binaries generated from other projects (cygwin, mingw, bcc ...)
8635 * sdcc/src/yacc.dsp: added
8637 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8638 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8639 and insert the version number definitions from .version
8641 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8643 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8644 added - genarate auto-host.h using auto-host_vc_in.h as template
8647 removed from CVS, generated automatically
8649 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8650 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8652 2002-08-11 Borut Razem <borut.razem AT siol.net>
8653 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8655 2002-08-10 Borut Razem <borut.razem AT siol.net>
8656 * src/SDCCmain.c (main):
8657 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8658 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8659 The consequence was that some temporary files were not removed.
8662 unification of code in functions tempfilename() and tempfile():
8663 function tempnam() is defined in Visual Studio 6.0 and .NET

8871 Previous fix was not good. basic blocks that have "break" or "return" are
8872 not really partof a loop , but live ranges used in these blocks should
