1470 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1472 * device/lib/printf_large.c: removed inline assembly for portability and
1473 readability. Use printf_fast if speed or size are more important.
1474 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1475 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1477 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1479 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1480 prevent compiler warning
1482 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1484 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1485 moved to level 0 and declared as static. Also they are explicit
1486 placed in access bank. This was necessery because some times they
1487 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1488 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1489 optimizations. Currently only compare to unsigned char is implemented,
1490 * src/pic16/gen.c: added fReturnIdx array,
1491 * (struct resolvedIfx) is moved to gen.h and made public,
1492 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1493 * (aopForSym): added an optimization to directly store in stack of
1494 the operand of a SEND iCode,
1495 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1496 but as registers instead (AOP_REG) using the fReturnIdx array,
1497 * (pic16_freeAsmop): remove the freed register from the
1498 _G.sregsAlloc field,
1499 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1500 a compare of 'WREG',
1501 * (pic16_popGetTempRegCond): changed function prototype, now
1502 function takes also a bitVector argument v which holds the current
1503 set of registers that are allocated for stack access by aopForSym,
1504 registers allocated in aopForSym for accessing stack symbols are not
1505 any more part of the functions usedRegs field,
1506 * (genCall): some times aopOp is called for a stack variable to be
1507 send, aopForSym might perform the push, if this is true make sure
1508 that genCall doesn't push the variable twice by testing _G.resDirect,
1509 * (genFunction): changed testing for unspecified interrupt number
1510 from 256 to INTNO_UNSPEC,
1511 * modified selection scheme of frame pointer generation. Previously
1512 if function did use local registers a frame pointer was generated,
1513 now a frame pointer is generated only if function has arguments
1514 (that need PLUSW2 register access), or has stack arguments, or the
1515 compiler is not instructed to omit the frame pointer,
1516 * (genEndFunction): before restoring local registers that were saved
1517 in the function preamble, also restore the registers that *might*
1518 have been allocated for stack access,
1519 * (genRet): removed some old comments,
1520 * (genCmp, the active (RN's) version): added a call to the
1521 pic16_genCmp_special function to perform the compare with a more
1522 robust and optimized way,
1523 * (genInline): a feature has been added in inline code generation,
1524 which allows a wildcard variable substitution when writing inline
1525 assembly. Code is incomplete and experimental therefore undocumented,
1526 * (genCast): changed order of aopOp for result and right to allow
1527 aopForSym to directly load the result if possible,
1528 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1529 perform an optimized compare on some selected special occasions,
1530 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1531 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1532 generate an IVT any more,
1533 * src/pic16/main.c (pic16_optionsTable): added command line option
1535 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1536 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1538 * src/pic16/NOTES: Raphael Neider added in list of active developers
1539 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1540 jumptable_end to prevent bug #,
1541 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1542 inCond and outCond fields,
1543 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1544 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1545 turn off register spilling,
1546 * (packRegsForOneUse): synced with other ports' versions although it
1547 is not used currently,
1548 * (pic16_packRegisters): added an optimization while reading
1549 structure bitfields, some registers may be saved (malloc code is
1550 decreased by 80 bytes)
1552 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1554 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1555 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1556 this can be optimized more?
1558 2005-03-10 Raphael Neider <rneider AT web.de>
1560 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1561 genNearPointerGet): (hopefully) fixed access to bitfields via
1562 pointers (p->bitN = x; and x = p->bitN; failed)
1564 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2175 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2177 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
2179 (setFromConditionArgs): friendly operand parser for peephole rules,
2180 (operandBaseName, operandsNotRelated): new peephole condition
2181 "operandsNotRelated" -- similar to "operandsNotSame", but takes
2182 architecture specific register naming into account, handles n-way
2183 comparisons, and supports quoted literals
2184 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

2194 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2196 Adding support for replacing ljmps with sjmps in jumptables
2197 generated for switch statements. For now you need to set the
2198 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2199 Now 4 algorithms for mcs51 jumptable generation are used:
2200 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2201 addresses loaded pc-relative for up to 112 cases and stack-pushing
2202 target addresses loaded with offset from dptr for up to 256 cases.
2204 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2205 * src/mcs51/main.c: adapted constants for switch table generation
2206 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2228 Large cummulative patch for pic16 port.
2229 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2230 to call when a stack overflow occurs,
2231 * (malloc.h): added CVS Id tag,
2232 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2234 * added libc directory. The current version of LibC contains string
2235 functions, ctype functions and macros and some functions of the
2236 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2237 be extensively tested in the future. Standard disclaimer here.
2238 Library is not automatically build yet. But one can build it by
2239 invoking 'make' inside the libc directory.
2240 * added ADC library under libio. Preliminary version yet.
2242 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2249 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2250 * (pic16_storeForReturn): optimized return of 0,
2251 * (genCmp): experimental code for new genCmp which uses PIC18's
2252 special compare&skip instructions. Initial tests fail some times
2253 with variables grater than 1 byte in size, so new code is disabled,
2254 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2256 * (genCast): began a fix to optimize the casting of a bit to another
2257 bit, now assigning a bitfield to another bitfield will fail, sorry,
2258 * src/pic16/main.c: disabled the use of lr-support feature,
2259 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2260 * added some function prototypes, added function _debugf prototype,
2261 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2262 bits with offset (case PO_GPR_BIT),
2263 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2265 * (isBankInstruction): modified to return 0 for no banking instruction,
2266 and 1 for banking instruction,
2267 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2268 caused stop processing pCodes after a inline assembly block,
2269 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2270 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2271 registers when it shouldn't,
2272 * src/pic16/ralloc.c (allocReg): add preliminary support for
2273 supporting a limited set of temporary registers,
2275 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2277 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2278 genDataPointerSet): ensure assignments always copy in MSB to LSB
2280 (loadRegFromAop): recognize CLRH optimization,
2281 (genFunction): optimize RECEIVE iCodes in reentrant functions
2283 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2285 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2286 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2288 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
2289 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
2290 contiguous with data
2292 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2294 * device/lib/_gptrget.c (_gptrget),
2295 * device/lib/_gptrgetc.c (_gptrgetc),
2296 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2297 instead of sjmp to ret
2298 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2299 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2301 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5271 * src/SDCCval.c (cheapestVal): added missing checks
5272 * src/SDCCicode.c (usualBinaryConversions): fixed condition
5273 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
5275 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
5277 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
5280 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5282 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5283 loaded with the linker search paths (-L arguments) and the libraries
5284 to be linked with the current source (-l arguments). Changes
5285 currently will affect only the pic16 port.
5286 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5287 include path the port specific paths and port specific libraries,
5288 * gplink command now contains the $3 argument,
5289 * src/pic16/device.h,
5290 * src/pic16/device.c,: structure PIC_device is made public and
5291 renamed to PIC16_device, the same for variable Pics which is renamed
5292 to Pics16. Updated all references to them.
5293 * src/pic16/glue.c (pic16glue): corrected bug with code
5294 initialization which bypassed the variable initializations block.
5296 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5297 COMPILE_FLAGS and added the --nostdinc option
5299 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5301 * device/include/mc68hc908jb8.h: Register defs for another member
5302 of the hc08 family. Contributed by Bjorn Bringert - thanks!
5304 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5306 Documenting changes from previous commits.
5307 * configure.in (version 1.56),
5308 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5309 when generating output files to configure the pic16 library,
5310 but now I've commented it out, since gputils aren't installed in the
5311 SF compile farm, so library won't compile
5313 * device/lib/Makefile.in (version 1.56): initially I've added in
5314 target 'all' the prerequestive 'model-pic16' so it compiled the
5315 pic16 library, but now I've commented it out for the same reasons
5317 * added targets 'model-pic16' and 'objects-pic16' to compile the
5319 * added target 'port-specific-objects-pic16' to handle the
5320 generated libraries and copy them into the build/ directory
5321 * added target 'clean-intermediate-pic16' to clean intermediate
5322 files into pic16 directory
5323 * in target 'installdirs' added line to create directory pic16 in
5324 the installation path
5326 * device/include/Makefile.in (version 1.11): in target 'install'
5327 added lines to copy all header files to installation path,
5328 * in target 'installdirs' added line create directory for pic16
5329 headers in the installation path
5331 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5342 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5344 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5345 option so that it actually works. Made it specific to the z80, since
5346 the gbz80 doesn't have these kinds of I/O ports.
5348 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5350 * device/include/z180.h,

5357 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5358 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5359 portmode; added deprecation warning for bank= and protmode= forms.
5360 Also, guard against buffer overflow.
5361 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5363 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5365 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5366 changed interrupt vector table generation to only emit declared vectors.
5367 * device/include/Makefile.in: added missing backslash
5368 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5370 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5372 Mainly changes to support compilation of the device libraries
5373 * src/pic16/device.c: stack is allocated via symbol and not
5374 via literal number. The symbol is placed in the corresponding
5375 position of the data ram
5376 * (pic16_dump_section): relocatable and absolute uninitialized
5377 data are now emitted in sorted order to reduce section naming,
5378 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5379 weren't marked as being in the access bank,
5381 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5383 Added portion of GNU PIC Library under the directory
5384 device/include/pic16 and device/lib/pic16. These files
5385 contain the declarations of SFRs for the PIC18Fxx2 devices.
5386 The directory is initialized via configure from toplevel.
5388 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5390 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5391 the spilllocations to be compared correctly
5393 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5395 * src/SDCCast.c (decorateType): fixed bug introduced today
5397 2004-01-12 Borut Razem <borut.razem AT siol.net>
5399 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5402 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5404 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5405 in simpler and even better code
5407 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5409 * src/SDCCicode.c (operandOperation): fixed bug #874819

5413 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5415 * doc/sdccman.lyx: Moved and added some sections, small changes
5416 all over. Telling LaTeX to be less strict with word spacing
5417 to better keep the right margin. Changed some notes about
5418 maintainance of the ports in section 3.2.1 - is it OK like this?
5420 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5422 SDCC source changes:
5423 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5457 UPPER for immediate operands,
5458 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5460 * src/pic16/peeph.def: all peepholes with movff are commented out,
5461 because there is a problem in the pcode peep optimizer,
5462 * src/pic16/ralloc.c: the register allocator can now reuse local
5463 function symbols for another function. This saves register usage.
5464 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5466 Added file src/pic16/NOTES with information about program writing on
5467 the current port version.

5499 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5502 * src/z80/main.c: added missed needLinkerScript flags (more than
5503 one port structure defined in these file)
5504 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5520 needLinkerScript flag
5522 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5523 * src/pic/glue.c: added variable udata_section_name to
5524 override default uninitialized data segment definition for
5525 devices only with SHAREBANK memory (reported from Erik Epetrich)
5526 * (pic14emitOverlay): modified to emit a commented overlay segment
5527 directive when no overlay data exist
5528 * (picglue): modified to emit uninitialized data segment
5529 according to udata_section_name

5539 2004-01-07 Borut Razem <borut.razem AT siol.net>
5541 * support/scripts/sdcc.nsi: update PATH
5542 * support/scripts/sdcc.ico: craeted
5544 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5555 include information about variables allocated to the overlay
5558 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5560 * as/mcs51/lkmain.c: Help about -Y option

5572 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5574 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5575 (default behaviour).
5577 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5579 A python script to validate compiler diagnostic messages. It can be
5580 used to verify that sdcc complains about bad c source code and
5581 gives a good location of the error.
5582 * support/valdiag/Makefile,
5583 * support/valdiag/valdiag.py,
5584 * support/valdiag/tests/*
5586 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5599 * src/common.h: added ifndef/define/endif macros
5600 around the header file.
5601 Bug reported from Jesus Calvino-Fraga
5603 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5605 * sdcc.spec: updated
5606 * device/include/Makefile.in: don't install CVS directories
5607 * device/lib/Makefile.in: added removal of CVS directories after install
5608 * doc/Makefile: fixed install, added local_icons
5609 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5610 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5611 * src/ds390/gen.c (genRightShift): fixed bug #870788
5612 * src/SDCCast.c (decorateType): fixed bug #870781
5614 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5616 PIC16 port related changes:
5617 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5618 added variable stackPos,
5620 * gen.c: genCall, assignResultValue: added support for
5621 pushing/retrieving function parameters to/from stack,
5622 genFunction,genEndFunction: setup stack frame for the
5624 genAddrOf: will be changed according to bug 863624
5626 * added files genutils.c and genutils.h which contain gen*
5627 debugged and optimised functions extracted from gen.c
5629 * glue.c: added variable 'externs' which holds extern symbols,
5630 pic16emitRegularMap: is modified to properly handle relocatable
5631 symbols under the new scheme,
5632 pic16createInterruptVect: is modified
5633 pic16printPublics: is modified to emit 'global' assembler directives,
5634 added pic16_printExterns to print extern symbols,
5635 pic16glue: initializes stack/frame pointer in the beginning of
5636 the assembly output. Temporary hack, will be corrected later,
5637 because gplink yet does not support stack and SDCC does not
5638 yet support a type of crt0.o object to create the final binary.
5640 * Removed many lines that contain 8051 legacy code.
5641 * The code is finally placed under a 'code' directive.
5642 * Added port specific options.
5644 * _process_pragma: simplified since now we do not need *special*
5645 include file to define SFR registers. But a separate header
5646 will be needed. This will be developed later.
5647 * _pic16_parseOptions: added, parses port specific options:
5648 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5649 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5650 --preplace-udata-with=
5652 * _pic16_setDefaultOptions: modified to initialize section names,
5653 but hack is temporarly out of order since it needs improvement.
5654 * _pic16_genAssemblerPreamble: configuration words are emitted by
5655 their address instead of their name. This part is incomplete and
5656 supports only the 18Fxx2 devices. Other devices will emit an error
5657 during assembly since they do not contain the same set of config
5659 * _pic16_genIVT: is modified,
5661 * pcode.c: added definitions for some hardware registers that are needed
5663 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5664 All PCI entries are updated. Now LFSR is supported.
5665 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5666 * added pic16_newpCodeOpLit2 to support instructions with
5667 two literal arguments
5668 * pic16_pCode2str: corrected code that emits assembler instructions
5669 with two literal operands and those that have an access bit modifier
5670 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5671 this fixes a bug which caused some labels to be lost, when an
5672 assembler directive was added, i.e. banksel,
5673 * pic16_FixRegisterBanking: improved logic that causes the insertion
5675 * InlineFunction: functions that are called once, are not any more
5676 inlined. This can be a port option in the future,
5678 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5680 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5681 hold the corresponding uninitialized symbols,
5682 * pic16_allocProcessorRegister: registers have explicit marked the
5684 * pic16_allocInternalRegister: registers are explicit marked as
5686 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5687 processing list, so bit registers were lost,
5690 * ralloc.h: added field 'accessBank' and original symbol operand
5691 in register definition,
5692 * removed the field isMapped from register definition,
5694 ** Several functions have been removed from various sources:
5695 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5696 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5697 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5698 pic16_assignRelocatableRegisters
5700 ** others have been introduced:
5701 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5702 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5704 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5706 * support/scripts/inc2h.pl: changed definition of BIT_AT
5707 to emit 'sbit at' instead of 'bit at'. This was a request.
5709 PIC16 port related preliminary changes:
5710 * gen.c: prefixed function popRegFromString with
5711 pic16_ and all references to it corrected
5712 * pcode.c: all pic16_pc_* hardware registers prefixed
5713 with underscore (_),
5714 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5715 * ralloc.c: newReg(): when register is REG_SFR then
5716 set address to rIdx,
5717 pic16_allocProcessorRegister(): marks register wasUsed=0
5718 pic16_writeUsedRegs(): added a call to assign processor
5719 registers via pic16_assignFixedRegisters
5721 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5723 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5724 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5725 variables in unused register banks. Also the SSEG is placed
5726 wherever there is enough space for it, and IDATA can be anywhere
5727 in internal RAM. For now compile using -Wl-Y[stack_size].
5728 The mem file is different for this option as well, since it
5729 makes no sense of talking about DSEG lenght.
5731 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5733 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5734 in certain cases, e.g. when ROM assignment, patch provided
5735 from Albert den Haan.
5737 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6753 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6755 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6756 these ports have their own __sdcc_external_start()
6758 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6760 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6761 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6762 type for bits was changed. It resulted in bit variables becoming
6763 global, which is not permitted in PIC 14 assembly output.
6765 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6767 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6769 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6771 Z80 and MCS51 linkers complaint if a public symbol is defined

6780 A few small changes that speed up the peephole optimizer.
6784 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6786 Try to make the peephole optimizer smarter by maintaining
6787 an association between the assembly source code and the
6788 iCodes that originated them. Put this information to use
6789 with a new peephole rule condition "notVolatile" so that
6790 the rules can be aggressive yet still safe.
6795 * src/mcs51/peeph.def
6797 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6801 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6802 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6803 if the left or right operand symbols have the accuse flag set.
6805 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6807 Changed the type of the result of the ! (NOT) operator to char;
6808 previously it returned the same type as the source. This allows
6809 us to eliminate all the genFloatNot functions (all of its target
6810 implementations were very buggy) since !float can use the same
6813 * src/SDCCicode.c (ast2iCode): ! returns char

6822 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6823 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6824 during interrupts. Ensure WSAVE is located at a shared bank address.
6825 2. Fixed page selection in some places
6826 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6827 the registers name strings.
6828 4. Fixed "signed / unsigned compare" compiler warnings.
6829 5. The PIC port manages its own allocation of the general purpose
6830 registers, but makes no attempt to reuse them. As a result when
6831 compiling it soon runs out of general purpose registers. Some
6832 additional code was added to the files pcode.c and device.c to walk
6833 through the function call tree and rename the registers so that they
6843 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6844 genPlus() & genMinus() when the result is the same as left or right

6850 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6852 Made bitfield a distinct type from bit so that bitfields
6853 convert as per ANSI C and bits retain their traditional
6854 boolean style behaviour. Implemented bitfield support in
6862 * src/ds390/gen.c: bit v bitfield split
6863 * src/z80/gen.c: New support for bitfields
6864 * support/regression/tests/bitfields.c: reenabled z80,
6867 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6869 Rules 246.x, 247.x relate to bitfields, the others speed up
6870 access to xdata mapped I/O devices.
6872 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6874 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6876 Cleaned up genPackBits and genUnpackBits and added two helper
6877 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6878 for literal assignments in genPackBits (thanks to Frieder for
6884 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6886 Fixed bug #748310 (pointer to function type mishandled when the
6887 function name is omitted). Also fixed a SIGSEGV when a function
6888 attribute (reentrant, etc) is used on a non-function or on a
6889 function but misplaced before the parameter list.
6891 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6893 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6916 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6918 Made the constant following the "interrupt" keyword optional. If
6919 omitted, the function will not automatically be given an entry
6920 in the interrupt vector table (similar to #pragma NOIV, but
6921 less syntacticly kludgy). The interrupt number is also now
6922 range checked. Also fixed a bug in the high order bit example

6936 * src/SDCCicode.c (operandOperation): rewritten some ops
6937 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6938 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6940 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6941 be re-activated by defining REDUCE_LITERALS)
6942 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6943 unsigned, but are signed by default
6944 * src/SDCCval.c (constVal): rearranged
6945 * src/SDCCval.c (valMod): preliminary fix
6946 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7398 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7399 the regression tests I'm not brave enough to enable 245.b, 245.c
7400 * doc/sdccman.lyx: added latex preamble for hyperref package.
7401 Using pdflatex this will give you a hyperlinked pdf file with
7402 bookmarks. (prepend '%' before /usepackage if this breaks something)

7440 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7442 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7443 it can be defined with CFLAGS when running configure
7444 * src/SDCCmain.c: fixed compiling + linking with object files
7446 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7448 * configure.in: configure for pic16 port,
7449 added --disable-pic16-port
7450 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7451 * src/SDCCmain.c: linkOptions is changed to set *,
7452 added if/endif conditional macros to remove options help
7453 messages from optionsTable when a port is not configured, added
7454 support for the PIc16 port in the ports table, when executing
7455 the compiler with no port specified on command line, a default
7456 port is selected with the new macro DEFAULT_PORT which is
7457 defined in port.h, in setDefaultOptions() linkOptions is removed
7458 from initialization assignment, since now it is a set,
7459 parseCmdLine uses setParseWithComma for linkOptions, in
7460 linkEdit() linkOptions are accessed with new function indexSet()
7461 which returns the i'th item of a set variable. See SDCCset.c, in
7462 linkEdit() when calling buildCmdLine(), added linkOptions as
7463 last argument. Now users can pass arguments to gplink via the
7464 -Wl option, main() uses pic16glue() to glue up pic16 programs
7465 * src/SDCCpeeph.c: various changes to support pic16

7474 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7476 * src/pic16/glue.c: commented out some error producing lines
7477 * src/pic16/main.c: __config directives are commented out to stop
7478 gpasm complaining and test the linkage with gplink, _linkCmd and
7479 _asmCmd changed to be more gplink and gpasm friendly
7480 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7481 produced an error when parsed, peep rule 12 is added to utilize
7482 movff, but it is commented out since the pCode does not support
7483 yet a command with 2 address arguments
7485 2003-05-18 <johan AT balder>
7487 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7488 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7507 on entry now. Add tbreak. Other enhancements and fixes for use
7510 2003-05-12 Borut Razem <borut.razem AT siol.net>
7512 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7514 2003-05-11 Borut Razem <borut.razem AT siol.net>
7516 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7517 the path of bin directory, so that PATH is the only env. variable, which has to be set
7518 in case of standard installation.
7519 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8548 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8550 * in \sdcc\as\mcs51\ changed these files in order to create an
8551 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8552 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8553 following files to include the previous two files: aslink.dsp,
8554 Makefile.aslink, Makefile.bcc, and Makefile.in.
8556 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8557 .adb instead of .cdb
8559 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8561 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8562 value from option --iram-size.
8564 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8566 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8569 2002-09-18 <wiml AT hhhh.org>
8571 * SDCClrange.h: exposed setFromRange() and setToRange()
8572 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8573 packRegsForAccUse() (bug 542397)
8574 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8575 multiple times and emitting the fetch operations more than once
8576 added aopGetUsesAcc() function to allow binary operators to
8577 fetch their operands in the correct order; made genMinus() emit
8578 compact code for X = LITERAL - Y
8580 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8581 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8582 sprintf() in line 1267.
8584 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8585 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8588 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8589 Changes to aslink (All the changes are marked with 'JCF'):
8591 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8594 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8595 area BSEG. Also moves, if possible, the DATA area down into the internal
8596 ram so more space is available.
8598 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8601 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8602 not bytes. Function summary() which creates a memory usage summary
8603 file with extension .mem. Reports of overlaping stack and small stack
8604 size. If the space for the stack is less than 16 bytes aslink trows a
8607 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8608 the 8051. Option 'y' for memory summary output file.
8610 Changes to sdcc (All the changes are marked with 'JCF'):
8612 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8614 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8615 overlaying area for it (uses RegBankUsed[4]).
8617 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8618 bank zero as used by default. By default aslink locates the stack
8619 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8620 the creation of the .mem file. Delegates the allocation of data area
8621 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8622 the begining of the stack area to aslink.
8624 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8625 glue() in SDCCglue.c creates an area for it.
8627 2002-09-03 Borut Razem <borut.razem AT siol.net>
8628 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8629 sdcc/src/pic/glue.c:
8630 introduced atexit() handler for teporay files removal in case of
8631 errors, assertions, ...
8633 2002-08-29 Borut Razem <borut.razem AT siol.net>
8634 * sdcc/support/cpp2/auto-host_vc_in.h:
8635 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8636 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8637 Maybe there is a similar problem with BORLANDC? It should be checked!
8639 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8640 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8641 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8642 was not executed, and the compiler (cl) launched a warning:
8643 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8645 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8646 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

8658 - added Release configuration in VS projects
8659 - review of compiler an linker options
8660 - VC .exe files are generated in bin_vc directory, not to interfere
8661 with binaries generated from other projects (cygwin, mingw, bcc ...)
8663 * sdcc/src/yacc.dsp: added
8665 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8666 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8667 and insert the version number definitions from .version

8681 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8683 2002-08-10 Borut Razem <borut.razem AT siol.net>
8684 * src/SDCCmain.c (main):
8685 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8686 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8687 The consequence was that some temporary files were not removed.
8690 unification of code in functions tempfilename() and tempfile():
8691 function tempnam() is defined in Visual Studio 6.0 and .NET
8693 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8695 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8696 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8697 - removed compiler command line option /WX: Treats all warnings as errors
8698 - update a list of source files, included into the project
8700 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

8711 added return 0 statements after assert() to make compiler happy
8713 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8714 added newline in the def file to keep MSC compiler satisfied
8716 * sdcc/src/z80/gen.c:
8717 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8718 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8719 - solved MSC error in function aopDump()
8721 * sdcc_vc.h: define PREFIX as "\\sdcc"
8723 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8779 were not getting allocated.
8781 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8784 Fixed left shift. Will promote the left side of a left shift
8785 if a) left shifting more than size of operand or b) when assigned
8786 to something size > size of left side
8788 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8898 * sdcc/src/SDCCloop.c:
8899 Previous fix was not good. basic blocks that have "break" or "return" are
8900 not really partof a loop , but live ranges used in these blocks should
8901 be live thru the entire loop, so set partOfLoop but don't add them to
8904 2002-02-21 <johan AT FRIJA>

9763 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
9765 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
9767 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.

9777 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
9779 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
9781 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
9783 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
9785 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
