2233 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2234 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2235 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2236 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2237 always available in leading double underscore form. The C99 support is
2238 mostly missing, but it's a start.
2239 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2240 reserved identifier "__data".
2242 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2318 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2320 * device/lib/printf_large.c: removed inline assembly for portability and
2321 readability. Use printf_fast if speed or size are more important.
2322 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2323 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2325 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2327 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2328 prevent compiler warning
2330 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2332 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2333 moved to level 0 and declared as static. Also they are explicit
2334 placed in access bank. This was necessery because some times they
2335 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2336 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2337 optimizations. Currently only compare to unsigned char is implemented,
2338 * src/pic16/gen.c: added fReturnIdx array,
2339 * (struct resolvedIfx) is moved to gen.h and made public,
2340 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2341 * (aopForSym): added an optimization to directly store in stack of
2342 the operand of a SEND iCode,
2343 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2344 but as registers instead (AOP_REG) using the fReturnIdx array,
2345 * (pic16_freeAsmop): remove the freed register from the
2346 _G.sregsAlloc field,
2347 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2348 a compare of 'WREG',
2349 * (pic16_popGetTempRegCond): changed function prototype, now
2350 function takes also a bitVector argument v which holds the current
2351 set of registers that are allocated for stack access by aopForSym,
2352 registers allocated in aopForSym for accessing stack symbols are not
2353 any more part of the functions usedRegs field,
2354 * (genCall): some times aopOp is called for a stack variable to be
2355 send, aopForSym might perform the push, if this is true make sure
2356 that genCall doesn't push the variable twice by testing _G.resDirect,
2357 * (genFunction): changed testing for unspecified interrupt number
2358 from 256 to INTNO_UNSPEC,
2359 * modified selection scheme of frame pointer generation. Previously
2360 if function did use local registers a frame pointer was generated,
2361 now a frame pointer is generated only if function has arguments
2362 (that need PLUSW2 register access), or has stack arguments, or the
2363 compiler is not instructed to omit the frame pointer,
2364 * (genEndFunction): before restoring local registers that were saved
2365 in the function preamble, also restore the registers that *might*
2366 have been allocated for stack access,
2367 * (genRet): removed some old comments,
2368 * (genCmp, the active (RN's) version): added a call to the
2369 pic16_genCmp_special function to perform the compare with a more
2370 robust and optimized way,
2371 * (genInline): a feature has been added in inline code generation,
2372 which allows a wildcard variable substitution when writing inline
2373 assembly. Code is incomplete and experimental therefore undocumented,
2374 * (genCast): changed order of aopOp for result and right to allow
2375 aopForSym to directly load the result if possible,
2376 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2377 perform an optimized compare on some selected special occasions,
2378 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2379 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2380 generate an IVT any more,
2381 * src/pic16/main.c (pic16_optionsTable): added command line option
2383 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2384 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2386 * src/pic16/NOTES: Raphael Neider added in list of active developers
2387 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2388 jumptable_end to prevent bug #,
2389 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2390 inCond and outCond fields,
2391 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2392 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2393 turn off register spilling,
2394 * (packRegsForOneUse): synced with other ports' versions although it
2395 is not used currently,
2396 * (pic16_packRegisters): added an optimization while reading
2397 structure bitfields, some registers may be saved (malloc code is
2398 decreased by 80 bytes)
2400 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2402 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2403 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2404 this can be optimized more?
2406 2005-03-10 Raphael Neider <rneider AT web.de>
2408 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2409 genNearPointerGet): (hopefully) fixed access to bitfields via
2410 pointers (p->bitN = x; and x = p->bitN; failed)
2412 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3027 (setFromConditionArgs): friendly operand parser for peephole rules,
3028 (operandBaseName, operandsNotRelated): new peephole condition
3029 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3030 architecture specific register naming into account, handles n-way
3031 comparisons, and supports quoted literals
3032 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3034 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3042 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3044 Adding support for replacing ljmps with sjmps in jumptables
3045 generated for switch statements. For now you need to set the
3046 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3047 Now 4 algorithms for mcs51 jumptable generation are used:
3048 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3049 addresses loaded pc-relative for up to 112 cases and stack-pushing
3050 target addresses loaded with offset from dptr for up to 256 cases.
3052 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3053 * src/mcs51/main.c: adapted constants for switch table generation
3054 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3076 Large cummulative patch for pic16 port.
3077 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3078 to call when a stack overflow occurs,
3079 * (malloc.h): added CVS Id tag,
3080 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3082 * added libc directory. The current version of LibC contains string
3083 functions, ctype functions and macros and some functions of the
3084 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3085 be extensively tested in the future. Standard disclaimer here.
3086 Library is not automatically build yet. But one can build it by
3087 invoking 'make' inside the libc directory.
3088 * added ADC library under libio. Preliminary version yet.
3090 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3097 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3098 * (pic16_storeForReturn): optimized return of 0,
3099 * (genCmp): experimental code for new genCmp which uses PIC18's
3100 special compare&skip instructions. Initial tests fail some times
3101 with variables grater than 1 byte in size, so new code is disabled,
3102 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3104 * (genCast): began a fix to optimize the casting of a bit to another
3105 bit, now assigning a bitfield to another bitfield will fail, sorry,
3106 * src/pic16/main.c: disabled the use of lr-support feature,
3107 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3108 * added some function prototypes, added function _debugf prototype,
3109 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3110 bits with offset (case PO_GPR_BIT),
3111 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3113 * (isBankInstruction): modified to return 0 for no banking instruction,
3114 and 1 for banking instruction,
3115 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3116 caused stop processing pCodes after a inline assembly block,
3117 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3118 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3119 registers when it shouldn't,
3120 * src/pic16/ralloc.c (allocReg): add preliminary support for
3121 supporting a limited set of temporary registers,
3123 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3125 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3126 genDataPointerSet): ensure assignments always copy in MSB to LSB
3128 (loadRegFromAop): recognize CLRH optimization,
3129 (genFunction): optimize RECEIVE iCodes in reentrant functions
3131 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3133 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3134 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3136 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3142 * device/lib/_gptrget.c (_gptrget),
3143 * device/lib/_gptrgetc.c (_gptrgetc),
3144 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
3145 instead of sjmp to ret
3146 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3147 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3149 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6130 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6131 loaded with the linker search paths (-L arguments) and the libraries
6132 to be linked with the current source (-l arguments). Changes
6133 currently will affect only the pic16 port.
6134 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6135 include path the port specific paths and port specific libraries,
6136 * gplink command now contains the $3 argument,
6137 * src/pic16/device.h,
6138 * src/pic16/device.c,: structure PIC_device is made public and
6139 renamed to PIC16_device, the same for variable Pics which is renamed
6140 to Pics16. Updated all references to them.
6141 * src/pic16/glue.c (pic16glue): corrected bug with code
6142 initialization which bypassed the variable initializations block.
6144 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6145 COMPILE_FLAGS and added the --nostdinc option
6147 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6149 * device/include/mc68hc908jb8.h: Register defs for another member
6150 of the hc08 family. Contributed by Bjorn Bringert - thanks!
6152 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6154 Documenting changes from previous commits.
6155 * configure.in (version 1.56),
6156 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6157 when generating output files to configure the pic16 library,
6158 but now I've commented it out, since gputils aren't installed in the
6159 SF compile farm, so library won't compile
6161 * device/lib/Makefile.in (version 1.56): initially I've added in
6162 target 'all' the prerequestive 'model-pic16' so it compiled the
6163 pic16 library, but now I've commented it out for the same reasons
6165 * added targets 'model-pic16' and 'objects-pic16' to compile the
6167 * added target 'port-specific-objects-pic16' to handle the
6168 generated libraries and copy them into the build/ directory
6169 * added target 'clean-intermediate-pic16' to clean intermediate
6170 files into pic16 directory
6171 * in target 'installdirs' added line to create directory pic16 in
6172 the installation path
6174 * device/include/Makefile.in (version 1.11): in target 'install'
6175 added lines to copy all header files to installation path,
6176 * in target 'installdirs' added line create directory for pic16
6177 headers in the installation path
6179 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6192 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6193 option so that it actually works. Made it specific to the z80, since
6194 the gbz80 doesn't have these kinds of I/O ports.
6196 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6198 * device/include/z180.h,

6211 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6213 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6214 changed interrupt vector table generation to only emit declared vectors.
6215 * device/include/Makefile.in: added missing backslash
6216 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
6218 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6220 Mainly changes to support compilation of the device libraries
6221 * src/pic16/device.c: stack is allocated via symbol and not
6222 via literal number. The symbol is placed in the corresponding
6223 position of the data ram
6224 * (pic16_dump_section): relocatable and absolute uninitialized
6225 data are now emitted in sorted order to reduce section naming,
6226 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6227 weren't marked as being in the access bank,
6229 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6231 Added portion of GNU PIC Library under the directory
6232 device/include/pic16 and device/lib/pic16. These files
6233 contain the declarations of SFRs for the PIC18Fxx2 devices.
6234 The directory is initialized via configure from toplevel.
6236 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6238 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6239 the spilllocations to be compared correctly
6241 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6243 * src/SDCCast.c (decorateType): fixed bug introduced today
6245 2004-01-12 Borut Razem <borut.razem AT siol.net>
6247 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

6250 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6252 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6253 in simpler and even better code
6255 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
6257 * src/SDCCicode.c (operandOperation): fixed bug #874819

6261 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6263 * doc/sdccman.lyx: Moved and added some sections, small changes
6264 all over. Telling LaTeX to be less strict with word spacing
6265 to better keep the right margin. Changed some notes about
6266 maintainance of the ports in section 3.2.1 - is it OK like this?
6268 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6305 UPPER for immediate operands,
6306 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6308 * src/pic16/peeph.def: all peepholes with movff are commented out,
6309 because there is a problem in the pcode peep optimizer,
6310 * src/pic16/ralloc.c: the register allocator can now reuse local
6311 function symbols for another function. This saves register usage.
6312 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6314 Added file src/pic16/NOTES with information about program writing on
6315 the current port version.

6324 * src/SDCCmain.c : fixed #872250: -l command line defined library
6325 files are scanned before standard library files
6327 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6344 gen51Code): more efficient parameter receive for --model-large
6347 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6350 * src/z80/main.c: added missed needLinkerScript flags (more than
6351 one port structure defined in these file)
6352 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6368 needLinkerScript flag
6370 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6371 * src/pic/glue.c: added variable udata_section_name to
6372 override default uninitialized data segment definition for
6373 devices only with SHAREBANK memory (reported from Erik Epetrich)
6374 * (pic14emitOverlay): modified to emit a commented overlay segment
6375 directive when no overlay data exist
6376 * (picglue): modified to emit uninitialized data segment
6377 according to udata_section_name

6382 arguments via -W option
6383 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6384 object file from '.rel' to '.o' in port->linker structure,
6385 changed size of fptr from 2 to 3 in port structure
6387 2004-01-07 Borut Razem <borut.razem AT siol.net>
6389 * support/scripts/sdcc.nsi: update PATH
6390 * support/scripts/sdcc.ico: craeted
6392 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6394 * device/include/Makefile.in: fix install
6395 * doc/Makefile: fix install
6397 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6399 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6401 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

6403 include information about variables allocated to the overlay
6406 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6408 * as/mcs51/lkmain.c: Help about -Y option

6420 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6422 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6423 (default behaviour).
6425 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6427 A python script to validate compiler diagnostic messages. It can be
6428 used to verify that sdcc complains about bad c source code and
6429 gives a good location of the error.
6430 * support/valdiag/Makefile,
6431 * support/valdiag/valdiag.py,
6432 * support/valdiag/tests/*
6434 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6436 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6445 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6447 * src/common.h: added ifndef/define/endif macros
6448 around the header file.
6449 Bug reported from Jesus Calvino-Fraga
6451 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6453 * sdcc.spec: updated
6454 * device/include/Makefile.in: don't install CVS directories
6455 * device/lib/Makefile.in: added removal of CVS directories after install
6456 * doc/Makefile: fixed install, added local_icons
6457 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6458 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6459 * src/ds390/gen.c (genRightShift): fixed bug #870788
6460 * src/SDCCast.c (decorateType): fixed bug #870781
6462 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6464 PIC16 port related changes:
6465 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6466 added variable stackPos,
6468 * gen.c: genCall, assignResultValue: added support for
6469 pushing/retrieving function parameters to/from stack,
6470 genFunction,genEndFunction: setup stack frame for the
6472 genAddrOf: will be changed according to bug 863624
6474 * added files genutils.c and genutils.h which contain gen*
6475 debugged and optimised functions extracted from gen.c
6477 * glue.c: added variable 'externs' which holds extern symbols,
6478 pic16emitRegularMap: is modified to properly handle relocatable
6479 symbols under the new scheme,
6480 pic16createInterruptVect: is modified
6481 pic16printPublics: is modified to emit 'global' assembler directives,
6482 added pic16_printExterns to print extern symbols,
6483 pic16glue: initializes stack/frame pointer in the beginning of
6484 the assembly output. Temporary hack, will be corrected later,
6485 because gplink yet does not support stack and SDCC does not
6486 yet support a type of crt0.o object to create the final binary.
6488 * Removed many lines that contain 8051 legacy code.
6489 * The code is finally placed under a 'code' directive.
6490 * Added port specific options.
6492 * _process_pragma: simplified since now we do not need *special*
6493 include file to define SFR registers. But a separate header
6494 will be needed. This will be developed later.
6495 * _pic16_parseOptions: added, parses port specific options:
6496 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6497 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6498 --preplace-udata-with=
6500 * _pic16_setDefaultOptions: modified to initialize section names,
6501 but hack is temporarly out of order since it needs improvement.
6502 * _pic16_genAssemblerPreamble: configuration words are emitted by
6503 their address instead of their name. This part is incomplete and
6504 supports only the 18Fxx2 devices. Other devices will emit an error
6505 during assembly since they do not contain the same set of config
6507 * _pic16_genIVT: is modified,
6509 * pcode.c: added definitions for some hardware registers that are needed
6511 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6512 All PCI entries are updated. Now LFSR is supported.
6513 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6514 * added pic16_newpCodeOpLit2 to support instructions with
6515 two literal arguments
6516 * pic16_pCode2str: corrected code that emits assembler instructions
6517 with two literal operands and those that have an access bit modifier
6518 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6519 this fixes a bug which caused some labels to be lost, when an
6520 assembler directive was added, i.e. banksel,
6521 * pic16_FixRegisterBanking: improved logic that causes the insertion
6523 * InlineFunction: functions that are called once, are not any more
6524 inlined. This can be a port option in the future,
6526 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6528 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6529 hold the corresponding uninitialized symbols,
6530 * pic16_allocProcessorRegister: registers have explicit marked the
6532 * pic16_allocInternalRegister: registers are explicit marked as
6534 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6535 processing list, so bit registers were lost,
6538 * ralloc.h: added field 'accessBank' and original symbol operand
6539 in register definition,
6540 * removed the field isMapped from register definition,
6542 ** Several functions have been removed from various sources:
6543 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6544 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6545 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6546 pic16_assignRelocatableRegisters
6548 ** others have been introduced:
6549 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6550 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6552 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6554 * support/scripts/inc2h.pl: changed definition of BIT_AT
6555 to emit 'sbit at' instead of 'bit at'. This was a request.
6557 PIC16 port related preliminary changes:
6558 * gen.c: prefixed function popRegFromString with
6559 pic16_ and all references to it corrected
6560 * pcode.c: all pic16_pc_* hardware registers prefixed
6561 with underscore (_),
6562 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6563 * ralloc.c: newReg(): when register is REG_SFR then
6564 set address to rIdx,
6565 pic16_allocProcessorRegister(): marks register wasUsed=0
6566 pic16_writeUsedRegs(): added a call to assign processor
6567 registers via pic16_assignFixedRegisters
6569 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6571 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6572 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6573 variables in unused register banks. Also the SSEG is placed
6574 wherever there is enough space for it, and IDATA can be anywhere
6575 in internal RAM. For now compile using -Wl-Y[stack_size].
6576 The mem file is different for this option as well, since it
6577 makes no sense of talking about DSEG lenght.
6579 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6581 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6582 in certain cases, e.g. when ROM assignment, patch provided
6583 from Albert den Haan.
6585 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7610 type for bits was changed. It resulted in bit variables becoming
7611 global, which is not permitted in PIC 14 assembly output.
7613 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7615 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7617 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7619 Z80 and MCS51 linkers complaint if a public symbol is defined
7620 in more than one library module:

7628 A few small changes that speed up the peephole optimizer.
7632 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7634 Try to make the peephole optimizer smarter by maintaining
7635 an association between the assembly source code and the
7636 iCodes that originated them. Put this information to use
7637 with a new peephole rule condition "notVolatile" so that
7638 the rules can be aggressive yet still safe.
7643 * src/mcs51/peeph.def
7645 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7649 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7650 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7651 if the left or right operand symbols have the accuse flag set.
7653 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7655 Changed the type of the result of the ! (NOT) operator to char;
7656 previously it returned the same type as the source. This allows
7657 us to eliminate all the genFloatNot functions (all of its target
7658 implementations were very buggy) since !float can use the same
7661 * src/SDCCicode.c (ast2iCode): ! returns char

7670 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7671 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7672 during interrupts. Ensure WSAVE is located at a shared bank address.
7673 2. Fixed page selection in some places
7674 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7675 the registers name strings.
7676 4. Fixed "signed / unsigned compare" compiler warnings.
7677 5. The PIC port manages its own allocation of the general purpose
7678 registers, but makes no attempt to reuse them. As a result when
7679 compiling it soon runs out of general purpose registers. Some
7680 additional code was added to the files pcode.c and device.c to walk
7681 through the function call tree and rename the registers so that they
7691 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7692 genPlus() & genMinus() when the result is the same as left or right
7694 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7698 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7700 Made bitfield a distinct type from bit so that bitfields
7701 convert as per ANSI C and bits retain their traditional
7702 boolean style behaviour. Implemented bitfield support in
7710 * src/ds390/gen.c: bit v bitfield split
7711 * src/z80/gen.c: New support for bitfields
7712 * support/regression/tests/bitfields.c: reenabled z80,
7715 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7717 Rules 246.x, 247.x relate to bitfields, the others speed up
7718 access to xdata mapped I/O devices.
7720 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7722 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7724 Cleaned up genPackBits and genUnpackBits and added two helper
7725 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7726 for literal assignments in genPackBits (thanks to Frieder for
7732 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7734 Fixed bug #748310 (pointer to function type mishandled when the
7735 function name is omitted). Also fixed a SIGSEGV when a function
7736 attribute (reentrant, etc) is used on a non-function or on a
7737 function but misplaced before the parameter list.
7739 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7741 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7742 * support/Util/SDCCerr.h,
7743 * support/Util/SDCCerr.c: Added func attr misuse error msg

7764 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7766 Made the constant following the "interrupt" keyword optional. If
7767 omitted, the function will not automatically be given an entry
7768 in the interrupt vector table (similar to #pragma NOIV, but
7769 less syntacticly kludgy). The interrupt number is also now
7770 range checked. Also fixed a bug in the high order bit example
7777 * support/Util/SDCCerr.c
7778 * support/Util/SDCCerr.h

7788 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7789 be re-activated by defining REDUCE_LITERALS)
7790 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7791 unsigned, but are signed by default
7792 * src/SDCCval.c (constVal): rearranged
7793 * src/SDCCval.c (valMod): preliminary fix
7794 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7837 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7838 * src/SDCCval.c (valDiv, valMod): fixed signdness
7839 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7840 signedness of modulo, left and right shift

8211 condition and ignore commands.
8213 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8215 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
8216 is in parts still quite out of date, I did changes as far as I felt makes sense
8217 for a non-native english speaker.
8218 Please feel free to add to the manual or to correct my changes.
8219 * doc/Makefile: undid touching the date of intermediate tex files.
8221 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8236 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8238 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
8239 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8240 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8241 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
8244 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8246 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8247 the regression tests I'm not brave enough to enable 245.b, 245.c
8248 * doc/sdccman.lyx: added latex preamble for hyperref package.
8249 Using pdflatex this will give you a hyperlinked pdf file with
8250 bookmarks. (prepend '%' before /usepackage if this breaks something)
8252 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8266 Applied patch from bug 737905 (renamed yylineo to mylineno):
8273 * src/pic16/pcode.c: Cleaned warnings
8274 * src/pic16/pcodeflow.c: Cleaned warnings
8275 * src/pic16/pcoderegs.c: Cleaned warnings

8288 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8290 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8291 it can be defined with CFLAGS when running configure
8292 * src/SDCCmain.c: fixed compiling + linking with object files
8294 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8296 * configure.in: configure for pic16 port,
8297 added --disable-pic16-port
8298 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8299 * src/SDCCmain.c: linkOptions is changed to set *,
8300 added if/endif conditional macros to remove options help
8301 messages from optionsTable when a port is not configured, added
8302 support for the PIc16 port in the ports table, when executing
8303 the compiler with no port specified on command line, a default
8304 port is selected with the new macro DEFAULT_PORT which is
8305 defined in port.h, in setDefaultOptions() linkOptions is removed
8306 from initialization assignment, since now it is a set,
8307 parseCmdLine uses setParseWithComma for linkOptions, in
8308 linkEdit() linkOptions are accessed with new function indexSet()
8309 which returns the i'th item of a set variable. See SDCCset.c, in
8310 linkEdit() when calling buildCmdLine(), added linkOptions as
8311 last argument. Now users can pass arguments to gplink via the
8312 -Wl option, main() uses pic16glue() to glue up pic16 programs
8313 * src/SDCCpeeph.c: various changes to support pic16

8322 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8324 * src/pic16/glue.c: commented out some error producing lines
8325 * src/pic16/main.c: __config directives are commented out to stop
8326 gpasm complaining and test the linkage with gplink, _linkCmd and
8327 _asmCmd changed to be more gplink and gpasm friendly
8328 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8329 produced an error when parsed, peep rule 12 is added to utilize
8330 movff, but it is commented out since the pCode does not support
8331 yet a command with 2 address arguments
8333 2003-05-18 <johan AT balder>
8335 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8336 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8337 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

8355 on entry now. Add tbreak. Other enhancements and fixes for use
8358 2003-05-12 Borut Razem <borut.razem AT siol.net>
8360 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8362 2003-05-11 Borut Razem <borut.razem AT siol.net>
8364 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8365 the path of bin directory, so that PATH is the only env. variable, which has to be set
8366 in case of standard installation.
8367 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9396 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9398 * in \sdcc\as\mcs51\ changed these files in order to create an
9399 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9400 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9401 following files to include the previous two files: aslink.dsp,
9402 Makefile.aslink, Makefile.bcc, and Makefile.in.
9404 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9405 .adb instead of .cdb
9407 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9409 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9410 value from option --iram-size.
9412 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9414 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9417 2002-09-18 <wiml AT hhhh.org>
9419 * SDCClrange.h: exposed setFromRange() and setToRange()
9420 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9421 packRegsForAccUse() (bug 542397)
9422 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9423 multiple times and emitting the fetch operations more than once
9424 added aopGetUsesAcc() function to allow binary operators to
9425 fetch their operands in the correct order; made genMinus() emit
9426 compact code for X = LITERAL - Y
9428 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9429 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9430 sprintf() in line 1267.
9432 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9433 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9436 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9437 Changes to aslink (All the changes are marked with 'JCF'):
9439 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9442 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9443 area BSEG. Also moves, if possible, the DATA area down into the internal
9444 ram so more space is available.
9446 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9449 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9450 not bytes. Function summary() which creates a memory usage summary
9451 file with extension .mem. Reports of overlaping stack and small stack
9452 size. If the space for the stack is less than 16 bytes aslink trows a
9455 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9456 the 8051. Option 'y' for memory summary output file.
9458 Changes to sdcc (All the changes are marked with 'JCF'):
9460 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9462 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9463 overlaying area for it (uses RegBankUsed[4]).
9465 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9466 bank zero as used by default. By default aslink locates the stack
9467 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9468 the creation of the .mem file. Delegates the allocation of data area
9469 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9470 the begining of the stack area to aslink.
9472 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9473 glue() in SDCCglue.c creates an area for it.
9475 2002-09-03 Borut Razem <borut.razem AT siol.net>
9476 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9477 sdcc/src/pic/glue.c:
9478 introduced atexit() handler for teporay files removal in case of
9479 errors, assertions, ...
9481 2002-08-29 Borut Razem <borut.razem AT siol.net>
9482 * sdcc/support/cpp2/auto-host_vc_in.h:
9483 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9484 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9485 Maybe there is a similar problem with BORLANDC? It should be checked!
9487 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9488 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9489 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9490 was not executed, and the compiler (cl) launched a warning:
9491 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9493 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9494 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

9506 - added Release configuration in VS projects
9507 - review of compiler an linker options
9508 - VC .exe files are generated in bin_vc directory, not to interfere
9509 with binaries generated from other projects (cygwin, mingw, bcc ...)
9511 * sdcc/src/yacc.dsp: added
9513 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9514 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9515 and insert the version number definitions from .version
9517 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9519 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9520 added - genarate auto-host.h using auto-host_vc_in.h as template

9529 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9531 2002-08-10 Borut Razem <borut.razem AT siol.net>
9532 * src/SDCCmain.c (main):
9533 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9534 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9535 The consequence was that some temporary files were not removed.
9538 unification of code in functions tempfilename() and tempfile():
9539 function tempnam() is defined in Visual Studio 6.0 and .NET
9541 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9543 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9544 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9545 - removed compiler command line option /WX: Treats all warnings as errors
9546 - update a list of source files, included into the project
9548 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9549 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9550 changed project type to Generic Project so that can be correcly converted to VS.NET project
9552 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC

9558 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9559 added return 0 statements after assert() to make compiler happy
9561 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9562 added newline in the def file to keep MSC compiler satisfied
9564 * sdcc/src/z80/gen.c:
9565 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9566 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9567 - solved MSC error in function aopDump()
9569 * sdcc_vc.h: define PREFIX as "\\sdcc"
9571 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9627 were not getting allocated.
9629 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9632 Fixed left shift. Will promote the left side of a left shift
9633 if a) left shifting more than size of operand or b) when assigned
9634 to something size > size of left side
9636 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9746 * sdcc/src/SDCCloop.c:
9747 Previous fix was not good. basic blocks that have "break" or "return" are
9748 not really partof a loop , but live ranges used in these blocks should
9749 be live thru the entire loop, so set partOfLoop but don't add them to
