1393 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1394 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1395 always available in leading double underscore form. The C99 support is
1396 mostly missing, but it's a start.
1397 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1398 reserved identifier "__data".

1476 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1478 * device/lib/printf_large.c: removed inline assembly for portability and
1479 readability. Use printf_fast if speed or size are more important.
1480 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1481 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1483 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1485 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1486 prevent compiler warning
1488 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1490 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1491 moved to level 0 and declared as static. Also they are explicit
1492 placed in access bank. This was necessery because some times they
1493 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1494 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1495 optimizations. Currently only compare to unsigned char is implemented,
1496 * src/pic16/gen.c: added fReturnIdx array,
1497 * (struct resolvedIfx) is moved to gen.h and made public,
1498 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1499 * (aopForSym): added an optimization to directly store in stack of
1500 the operand of a SEND iCode,
1501 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1502 but as registers instead (AOP_REG) using the fReturnIdx array,
1503 * (pic16_freeAsmop): remove the freed register from the
1504 _G.sregsAlloc field,
1505 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1506 a compare of 'WREG',
1507 * (pic16_popGetTempRegCond): changed function prototype, now
1508 function takes also a bitVector argument v which holds the current
1509 set of registers that are allocated for stack access by aopForSym,
1510 registers allocated in aopForSym for accessing stack symbols are not
1511 any more part of the functions usedRegs field,
1512 * (genCall): some times aopOp is called for a stack variable to be
1513 send, aopForSym might perform the push, if this is true make sure
1514 that genCall doesn't push the variable twice by testing _G.resDirect,
1515 * (genFunction): changed testing for unspecified interrupt number
1516 from 256 to INTNO_UNSPEC,
1517 * modified selection scheme of frame pointer generation. Previously
1518 if function did use local registers a frame pointer was generated,
1519 now a frame pointer is generated only if function has arguments
1520 (that need PLUSW2 register access), or has stack arguments, or the
1521 compiler is not instructed to omit the frame pointer,
1522 * (genEndFunction): before restoring local registers that were saved
1523 in the function preamble, also restore the registers that *might*
1524 have been allocated for stack access,
1525 * (genRet): removed some old comments,
1526 * (genCmp, the active (RN's) version): added a call to the
1527 pic16_genCmp_special function to perform the compare with a more
1528 robust and optimized way,
1529 * (genInline): a feature has been added in inline code generation,
1530 which allows a wildcard variable substitution when writing inline
1531 assembly. Code is incomplete and experimental therefore undocumented,
1532 * (genCast): changed order of aopOp for result and right to allow
1533 aopForSym to directly load the result if possible,
1534 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1535 perform an optimized compare on some selected special occasions,
1536 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1537 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1538 generate an IVT any more,
1539 * src/pic16/main.c (pic16_optionsTable): added command line option
1541 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1542 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1544 * src/pic16/NOTES: Raphael Neider added in list of active developers
1545 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1546 jumptable_end to prevent bug #,
1547 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1548 inCond and outCond fields,
1549 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1550 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1551 turn off register spilling,
1552 * (packRegsForOneUse): synced with other ports' versions although it
1553 is not used currently,
1554 * (pic16_packRegisters): added an optimization while reading
1555 structure bitfields, some registers may be saved (malloc code is
1556 decreased by 80 bytes)
1558 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1560 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1561 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1562 this can be optimized more?
1564 2005-03-10 Raphael Neider <rneider AT web.de>
1566 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1567 genNearPointerGet): (hopefully) fixed access to bitfields via
1568 pointers (p->bitN = x; and x = p->bitN; failed)
1570 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2183 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
2185 (setFromConditionArgs): friendly operand parser for peephole rules,
2186 (operandBaseName, operandsNotRelated): new peephole condition
2187 "operandsNotRelated" -- similar to "operandsNotSame", but takes
2188 architecture specific register naming into account, handles n-way
2189 comparisons, and supports quoted literals
2190 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

2200 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2202 Adding support for replacing ljmps with sjmps in jumptables
2203 generated for switch statements. For now you need to set the
2204 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2205 Now 4 algorithms for mcs51 jumptable generation are used:
2206 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2207 addresses loaded pc-relative for up to 112 cases and stack-pushing
2208 target addresses loaded with offset from dptr for up to 256 cases.
2210 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2211 * src/mcs51/main.c: adapted constants for switch table generation
2212 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2234 Large cummulative patch for pic16 port.
2235 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2236 to call when a stack overflow occurs,
2237 * (malloc.h): added CVS Id tag,
2238 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2240 * added libc directory. The current version of LibC contains string
2241 functions, ctype functions and macros and some functions of the
2242 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2243 be extensively tested in the future. Standard disclaimer here.
2244 Library is not automatically build yet. But one can build it by
2245 invoking 'make' inside the libc directory.
2246 * added ADC library under libio. Preliminary version yet.
2248 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2255 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2256 * (pic16_storeForReturn): optimized return of 0,
2257 * (genCmp): experimental code for new genCmp which uses PIC18's
2258 special compare&skip instructions. Initial tests fail some times
2259 with variables grater than 1 byte in size, so new code is disabled,
2260 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2262 * (genCast): began a fix to optimize the casting of a bit to another
2263 bit, now assigning a bitfield to another bitfield will fail, sorry,
2264 * src/pic16/main.c: disabled the use of lr-support feature,
2265 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2266 * added some function prototypes, added function _debugf prototype,
2267 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2268 bits with offset (case PO_GPR_BIT),
2269 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2271 * (isBankInstruction): modified to return 0 for no banking instruction,
2272 and 1 for banking instruction,
2273 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2274 caused stop processing pCodes after a inline assembly block,
2275 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2276 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2277 registers when it shouldn't,
2278 * src/pic16/ralloc.c (allocReg): add preliminary support for
2279 supporting a limited set of temporary registers,
2281 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2283 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2284 genDataPointerSet): ensure assignments always copy in MSB to LSB
2286 (loadRegFromAop): recognize CLRH optimization,
2287 (genFunction): optimize RECEIVE iCodes in reentrant functions
2289 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2291 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2292 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2294 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
2295 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
2296 contiguous with data
2298 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2300 * device/lib/_gptrget.c (_gptrget),
2301 * device/lib/_gptrgetc.c (_gptrgetc),
2302 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2303 instead of sjmp to ret
2304 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2305 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2307 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5286 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5288 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5289 loaded with the linker search paths (-L arguments) and the libraries
5290 to be linked with the current source (-l arguments). Changes
5291 currently will affect only the pic16 port.
5292 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5293 include path the port specific paths and port specific libraries,
5294 * gplink command now contains the $3 argument,
5295 * src/pic16/device.h,
5296 * src/pic16/device.c,: structure PIC_device is made public and
5297 renamed to PIC16_device, the same for variable Pics which is renamed
5298 to Pics16. Updated all references to them.
5299 * src/pic16/glue.c (pic16glue): corrected bug with code
5300 initialization which bypassed the variable initializations block.
5302 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5303 COMPILE_FLAGS and added the --nostdinc option
5305 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5307 * device/include/mc68hc908jb8.h: Register defs for another member

5310 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5312 Documenting changes from previous commits.
5313 * configure.in (version 1.56),
5314 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5315 when generating output files to configure the pic16 library,
5316 but now I've commented it out, since gputils aren't installed in the
5317 SF compile farm, so library won't compile
5319 * device/lib/Makefile.in (version 1.56): initially I've added in
5320 target 'all' the prerequestive 'model-pic16' so it compiled the
5321 pic16 library, but now I've commented it out for the same reasons
5323 * added targets 'model-pic16' and 'objects-pic16' to compile the
5325 * added target 'port-specific-objects-pic16' to handle the
5326 generated libraries and copy them into the build/ directory
5327 * added target 'clean-intermediate-pic16' to clean intermediate
5328 files into pic16 directory
5329 * in target 'installdirs' added line to create directory pic16 in
5330 the installation path
5332 * device/include/Makefile.in (version 1.11): in target 'install'
5333 added lines to copy all header files to installation path,
5334 * in target 'installdirs' added line create directory for pic16
5335 headers in the installation path
5337 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5350 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5351 option so that it actually works. Made it specific to the z80, since
5352 the gbz80 doesn't have these kinds of I/O ports.
5354 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5356 * device/include/z180.h,

5365 portmode; added deprecation warning for bank= and protmode= forms.
5366 Also, guard against buffer overflow.
5367 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5369 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5371 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5372 changed interrupt vector table generation to only emit declared vectors.
5373 * device/include/Makefile.in: added missing backslash
5374 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5376 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5378 Mainly changes to support compilation of the device libraries
5379 * src/pic16/device.c: stack is allocated via symbol and not
5380 via literal number. The symbol is placed in the corresponding
5381 position of the data ram
5382 * (pic16_dump_section): relocatable and absolute uninitialized
5383 data are now emitted in sorted order to reduce section naming,
5384 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5385 weren't marked as being in the access bank,
5387 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5389 Added portion of GNU PIC Library under the directory
5390 device/include/pic16 and device/lib/pic16. These files
5391 contain the declarations of SFRs for the PIC18Fxx2 devices.
5392 The directory is initialized via configure from toplevel.
5394 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5396 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5397 the spilllocations to be compared correctly
5399 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5401 * src/SDCCast.c (decorateType): fixed bug introduced today
5403 2004-01-12 Borut Razem <borut.razem AT siol.net>
5405 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5408 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5410 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5411 in simpler and even better code
5413 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5415 * src/SDCCicode.c (operandOperation): fixed bug #874819

5419 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5421 * doc/sdccman.lyx: Moved and added some sections, small changes
5422 all over. Telling LaTeX to be less strict with word spacing
5423 to better keep the right margin. Changed some notes about
5424 maintainance of the ports in section 3.2.1 - is it OK like this?
5426 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5428 SDCC source changes:
5429 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5462 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5463 UPPER for immediate operands,
5464 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5466 * src/pic16/peeph.def: all peepholes with movff are commented out,
5467 because there is a problem in the pcode peep optimizer,
5468 * src/pic16/ralloc.c: the register allocator can now reuse local
5469 function symbols for another function. This saves register usage.
5470 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5472 Added file src/pic16/NOTES with information about program writing on
5473 the current port version.

5482 * src/SDCCmain.c : fixed #872250: -l command line defined library
5483 files are scanned before standard library files
5485 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5502 gen51Code): more efficient parameter receive for --model-large
5505 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5508 * src/z80/main.c: added missed needLinkerScript flags (more than
5509 one port structure defined in these file)
5510 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5526 needLinkerScript flag
5528 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5529 * src/pic/glue.c: added variable udata_section_name to
5530 override default uninitialized data segment definition for
5531 devices only with SHAREBANK memory (reported from Erik Epetrich)
5532 * (pic14emitOverlay): modified to emit a commented overlay segment
5533 directive when no overlay data exist
5534 * (picglue): modified to emit uninitialized data segment
5535 according to udata_section_name

5541 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5542 object file from '.rel' to '.o' in port->linker structure,
5543 changed size of fptr from 2 to 3 in port structure
5545 2004-01-07 Borut Razem <borut.razem AT siol.net>
5547 * support/scripts/sdcc.nsi: update PATH
5548 * support/scripts/sdcc.ico: craeted
5550 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5553 * doc/Makefile: fix install
5555 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5557 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5559 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5561 include information about variables allocated to the overlay
5564 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5566 * as/mcs51/lkmain.c: Help about -Y option

5578 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5580 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5581 (default behaviour).
5583 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5585 A python script to validate compiler diagnostic messages. It can be
5586 used to verify that sdcc complains about bad c source code and
5587 gives a good location of the error.
5588 * support/valdiag/Makefile,
5589 * support/valdiag/valdiag.py,
5590 * support/valdiag/tests/*
5592 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5594 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5595 * src/SDCCsymt.c (newEnumType),

5603 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5605 * src/common.h: added ifndef/define/endif macros
5606 around the header file.
5607 Bug reported from Jesus Calvino-Fraga
5609 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5611 * sdcc.spec: updated
5612 * device/include/Makefile.in: don't install CVS directories
5613 * device/lib/Makefile.in: added removal of CVS directories after install
5614 * doc/Makefile: fixed install, added local_icons
5615 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5616 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5617 * src/ds390/gen.c (genRightShift): fixed bug #870788
5618 * src/SDCCast.c (decorateType): fixed bug #870781
5620 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5622 PIC16 port related changes:
5623 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5624 added variable stackPos,
5626 * gen.c: genCall, assignResultValue: added support for
5627 pushing/retrieving function parameters to/from stack,
5628 genFunction,genEndFunction: setup stack frame for the
5630 genAddrOf: will be changed according to bug 863624
5632 * added files genutils.c and genutils.h which contain gen*
5633 debugged and optimised functions extracted from gen.c
5635 * glue.c: added variable 'externs' which holds extern symbols,
5636 pic16emitRegularMap: is modified to properly handle relocatable
5637 symbols under the new scheme,
5638 pic16createInterruptVect: is modified
5639 pic16printPublics: is modified to emit 'global' assembler directives,
5640 added pic16_printExterns to print extern symbols,
5641 pic16glue: initializes stack/frame pointer in the beginning of
5642 the assembly output. Temporary hack, will be corrected later,
5643 because gplink yet does not support stack and SDCC does not
5644 yet support a type of crt0.o object to create the final binary.
5646 * Removed many lines that contain 8051 legacy code.
5647 * The code is finally placed under a 'code' directive.
5648 * Added port specific options.
5650 * _process_pragma: simplified since now we do not need *special*
5651 include file to define SFR registers. But a separate header
5652 will be needed. This will be developed later.
5653 * _pic16_parseOptions: added, parses port specific options:
5654 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5655 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5656 --preplace-udata-with=
5658 * _pic16_setDefaultOptions: modified to initialize section names,
5659 but hack is temporarly out of order since it needs improvement.
5660 * _pic16_genAssemblerPreamble: configuration words are emitted by
5661 their address instead of their name. This part is incomplete and
5662 supports only the 18Fxx2 devices. Other devices will emit an error
5663 during assembly since they do not contain the same set of config
5665 * _pic16_genIVT: is modified,
5667 * pcode.c: added definitions for some hardware registers that are needed
5669 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5670 All PCI entries are updated. Now LFSR is supported.
5671 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5672 * added pic16_newpCodeOpLit2 to support instructions with
5673 two literal arguments
5674 * pic16_pCode2str: corrected code that emits assembler instructions
5675 with two literal operands and those that have an access bit modifier
5676 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5677 this fixes a bug which caused some labels to be lost, when an
5678 assembler directive was added, i.e. banksel,
5679 * pic16_FixRegisterBanking: improved logic that causes the insertion
5681 * InlineFunction: functions that are called once, are not any more
5682 inlined. This can be a port option in the future,
5684 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5686 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5687 hold the corresponding uninitialized symbols,
5688 * pic16_allocProcessorRegister: registers have explicit marked the
5690 * pic16_allocInternalRegister: registers are explicit marked as
5692 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5693 processing list, so bit registers were lost,
5696 * ralloc.h: added field 'accessBank' and original symbol operand
5697 in register definition,
5698 * removed the field isMapped from register definition,
5700 ** Several functions have been removed from various sources:
5701 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5702 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5703 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5704 pic16_assignRelocatableRegisters
5706 ** others have been introduced:
5707 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5708 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5710 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5712 * support/scripts/inc2h.pl: changed definition of BIT_AT
5713 to emit 'sbit at' instead of 'bit at'. This was a request.
5715 PIC16 port related preliminary changes:
5716 * gen.c: prefixed function popRegFromString with
5717 pic16_ and all references to it corrected
5718 * pcode.c: all pic16_pc_* hardware registers prefixed
5719 with underscore (_),
5720 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5721 * ralloc.c: newReg(): when register is REG_SFR then
5722 set address to rIdx,
5723 pic16_allocProcessorRegister(): marks register wasUsed=0
5724 pic16_writeUsedRegs(): added a call to assign processor
5725 registers via pic16_assignFixedRegisters
5727 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5729 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5730 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5731 variables in unused register banks. Also the SSEG is placed
5732 wherever there is enough space for it, and IDATA can be anywhere
5733 in internal RAM. For now compile using -Wl-Y[stack_size].
5734 The mem file is different for this option as well, since it
5735 makes no sense of talking about DSEG lenght.
5737 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5739 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5740 in certain cases, e.g. when ROM assignment, patch provided
5741 from Albert den Haan.
5743 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6751 If they pop r0/r1 they must be called in the opposite order than aopOp().
6752 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6753 (resp. --stack-auto), prepared for --xstack

6759 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6761 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6762 these ports have their own __sdcc_external_start()
6764 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6766 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6767 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6768 type for bits was changed. It resulted in bit variables becoming
6769 global, which is not permitted in PIC 14 assembly output.
6771 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6773 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6775 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6777 Z80 and MCS51 linkers complaint if a public symbol is defined

6786 A few small changes that speed up the peephole optimizer.
6790 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6792 Try to make the peephole optimizer smarter by maintaining
6793 an association between the assembly source code and the
6794 iCodes that originated them. Put this information to use
6795 with a new peephole rule condition "notVolatile" so that
6796 the rules can be aggressive yet still safe.
6801 * src/mcs51/peeph.def
6803 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6807 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6808 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6809 if the left or right operand symbols have the accuse flag set.
6811 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6813 Changed the type of the result of the ! (NOT) operator to char;
6814 previously it returned the same type as the source. This allows
6815 us to eliminate all the genFloatNot functions (all of its target
6816 implementations were very buggy) since !float can use the same
6819 * src/SDCCicode.c (ast2iCode): ! returns char

6828 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6829 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6830 during interrupts. Ensure WSAVE is located at a shared bank address.
6831 2. Fixed page selection in some places
6832 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6833 the registers name strings.
6834 4. Fixed "signed / unsigned compare" compiler warnings.
6835 5. The PIC port manages its own allocation of the general purpose
6836 registers, but makes no attempt to reuse them. As a result when
6837 compiling it soon runs out of general purpose registers. Some
6838 additional code was added to the files pcode.c and device.c to walk
6839 through the function call tree and rename the registers so that they
6849 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6850 genPlus() & genMinus() when the result is the same as left or right

6856 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6858 Made bitfield a distinct type from bit so that bitfields
6859 convert as per ANSI C and bits retain their traditional
6860 boolean style behaviour. Implemented bitfield support in
6868 * src/ds390/gen.c: bit v bitfield split
6869 * src/z80/gen.c: New support for bitfields
6870 * support/regression/tests/bitfields.c: reenabled z80,
6873 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6875 Rules 246.x, 247.x relate to bitfields, the others speed up
6876 access to xdata mapped I/O devices.
6878 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6880 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6882 Cleaned up genPackBits and genUnpackBits and added two helper
6883 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6884 for literal assignments in genPackBits (thanks to Frieder for
6890 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6892 Fixed bug #748310 (pointer to function type mishandled when the
6893 function name is omitted). Also fixed a SIGSEGV when a function
6894 attribute (reentrant, etc) is used on a non-function or on a
6895 function but misplaced before the parameter list.
6897 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6899 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6922 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6924 Made the constant following the "interrupt" keyword optional. If
6925 omitted, the function will not automatically be given an entry
6926 in the interrupt vector table (similar to #pragma NOIV, but
6927 less syntacticly kludgy). The interrupt number is also now
6928 range checked. Also fixed a bug in the high order bit example

6942 * src/SDCCicode.c (operandOperation): rewritten some ops
6943 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6944 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6946 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6947 be re-activated by defining REDUCE_LITERALS)
6948 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6949 unsigned, but are signed by default
6950 * src/SDCCval.c (constVal): rearranged
6951 * src/SDCCval.c (valMod): preliminary fix
6952 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7404 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7405 the regression tests I'm not brave enough to enable 245.b, 245.c
7406 * doc/sdccman.lyx: added latex preamble for hyperref package.
7407 Using pdflatex this will give you a hyperlinked pdf file with
7408 bookmarks. (prepend '%' before /usepackage if this breaks something)

7424 Applied patch from bug 737905 (renamed yylineo to mylineno):
7431 * src/pic16/pcode.c: Cleaned warnings
7432 * src/pic16/pcodeflow.c: Cleaned warnings
7433 * src/pic16/pcoderegs.c: Cleaned warnings

7446 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7448 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7449 it can be defined with CFLAGS when running configure
7450 * src/SDCCmain.c: fixed compiling + linking with object files
7452 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7455 added --disable-pic16-port
7456 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7457 * src/SDCCmain.c: linkOptions is changed to set *,
7458 added if/endif conditional macros to remove options help
7459 messages from optionsTable when a port is not configured, added
7460 support for the PIc16 port in the ports table, when executing
7461 the compiler with no port specified on command line, a default
7462 port is selected with the new macro DEFAULT_PORT which is
7463 defined in port.h, in setDefaultOptions() linkOptions is removed
7464 from initialization assignment, since now it is a set,
7465 parseCmdLine uses setParseWithComma for linkOptions, in
7466 linkEdit() linkOptions are accessed with new function indexSet()
7467 which returns the i'th item of a set variable. See SDCCset.c, in
7468 linkEdit() when calling buildCmdLine(), added linkOptions as
7469 last argument. Now users can pass arguments to gplink via the
7470 -Wl option, main() uses pic16glue() to glue up pic16 programs
7471 * src/SDCCpeeph.c: various changes to support pic16

7482 * src/pic16/glue.c: commented out some error producing lines
7483 * src/pic16/main.c: __config directives are commented out to stop
7484 gpasm complaining and test the linkage with gplink, _linkCmd and
7485 _asmCmd changed to be more gplink and gpasm friendly
7486 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7487 produced an error when parsed, peep rule 12 is added to utilize
7488 movff, but it is commented out since the pCode does not support
7489 yet a command with 2 address arguments
7491 2003-05-18 <johan AT balder>
7493 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7494 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7518 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7520 2003-05-11 Borut Razem <borut.razem AT siol.net>
7522 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7523 the path of bin directory, so that PATH is the only env. variable, which has to be set
7524 in case of standard installation.
7525 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8554 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8556 * in \sdcc\as\mcs51\ changed these files in order to create an
8557 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8558 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8559 following files to include the previous two files: aslink.dsp,
8560 Makefile.aslink, Makefile.bcc, and Makefile.in.
8562 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8563 .adb instead of .cdb
8565 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8567 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8568 value from option --iram-size.
8570 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8572 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8575 2002-09-18 <wiml AT hhhh.org>
8577 * SDCClrange.h: exposed setFromRange() and setToRange()
8578 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8579 packRegsForAccUse() (bug 542397)
8580 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8581 multiple times and emitting the fetch operations more than once
8582 added aopGetUsesAcc() function to allow binary operators to
8583 fetch their operands in the correct order; made genMinus() emit
8584 compact code for X = LITERAL - Y
8586 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8587 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8588 sprintf() in line 1267.
8590 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8591 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8594 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8595 Changes to aslink (All the changes are marked with 'JCF'):
8597 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8600 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8601 area BSEG. Also moves, if possible, the DATA area down into the internal
8602 ram so more space is available.
8604 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8607 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8608 not bytes. Function summary() which creates a memory usage summary
8609 file with extension .mem. Reports of overlaping stack and small stack
8610 size. If the space for the stack is less than 16 bytes aslink trows a
8613 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8614 the 8051. Option 'y' for memory summary output file.
8616 Changes to sdcc (All the changes are marked with 'JCF'):
8618 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8620 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8621 overlaying area for it (uses RegBankUsed[4]).
8623 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8624 bank zero as used by default. By default aslink locates the stack
8625 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8626 the creation of the .mem file. Delegates the allocation of data area
8627 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8628 the begining of the stack area to aslink.
8630 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8631 glue() in SDCCglue.c creates an area for it.
8633 2002-09-03 Borut Razem <borut.razem AT siol.net>
8634 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8635 sdcc/src/pic/glue.c:
8636 introduced atexit() handler for teporay files removal in case of
8637 errors, assertions, ...
8639 2002-08-29 Borut Razem <borut.razem AT siol.net>
8640 * sdcc/support/cpp2/auto-host_vc_in.h:
8641 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8642 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8643 Maybe there is a similar problem with BORLANDC? It should be checked!
8645 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8646 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8647 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8648 was not executed, and the compiler (cl) launched a warning:
8649 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8651 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8652 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

8663 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8664 - added Release configuration in VS projects
8665 - review of compiler an linker options
8666 - VC .exe files are generated in bin_vc directory, not to interfere
8667 with binaries generated from other projects (cygwin, mingw, bcc ...)
8669 * sdcc/src/yacc.dsp: added
8671 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8672 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8673 and insert the version number definitions from .version
8675 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8677 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8681 removed from CVS, generated automatically
8683 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8684 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8686 2002-08-11 Borut Razem <borut.razem AT siol.net>
8687 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8689 2002-08-10 Borut Razem <borut.razem AT siol.net>
8690 * src/SDCCmain.c (main):
8691 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8692 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8693 The consequence was that some temporary files were not removed.
8696 unification of code in functions tempfilename() and tempfile():
8697 function tempnam() is defined in Visual Studio 6.0 and .NET
8699 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8701 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8702 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8703 - removed compiler command line option /WX: Treats all warnings as errors
8704 - update a list of source files, included into the project
8706 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8707 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8708 changed project type to Generic Project so that can be correcly converted to VS.NET project
8710 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8712 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

8716 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8717 added return 0 statements after assert() to make compiler happy
8719 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8720 added newline in the def file to keep MSC compiler satisfied
8722 * sdcc/src/z80/gen.c:
8723 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8724 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8725 - solved MSC error in function aopDump()
8727 * sdcc_vc.h: define PREFIX as "\\sdcc"
8729 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8781 Initialized the new field char *Processor field to NULL in all ports
8784 Compiler generated registers for interrupt context saving
8785 were not getting allocated.
8787 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8790 Fixed left shift. Will promote the left side of a left shift
8791 if a) left shifting more than size of operand or b) when assigned
8792 to something size > size of left side
8794 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8904 * sdcc/src/SDCCloop.c:
8905 Previous fix was not good. basic blocks that have "break" or "return" are
8906 not really partof a loop , but live ranges used in these blocks should
8907 be live thru the entire loop, so set partOfLoop but don't add them to
8910 2002-02-21 <johan AT FRIJA>

8939 Karl and Johan start ucsim XA support. Most dissassembly working,
8940 about 75% emulation done(plenty of work remaining).
8942 * sim/ucsim/z80.src:
8943 Add Z80 support to ucsim, add test-ucz80 regression test,
8944 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
