2249 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2250 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2251 always available in leading double underscore form. The C99 support is
2252 mostly missing, but it's a start.
2253 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2334 * device/lib/printf_large.c: removed inline assembly for portability and
2335 readability. Use printf_fast if speed or size are more important.
2336 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2337 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2339 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2341 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2342 prevent compiler warning
2344 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2346 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2347 moved to level 0 and declared as static. Also they are explicit
2348 placed in access bank. This was necessery because some times they
2349 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2350 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2351 optimizations. Currently only compare to unsigned char is implemented,
2352 * src/pic16/gen.c: added fReturnIdx array,
2353 * (struct resolvedIfx) is moved to gen.h and made public,
2354 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2355 * (aopForSym): added an optimization to directly store in stack of
2356 the operand of a SEND iCode,
2357 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2358 but as registers instead (AOP_REG) using the fReturnIdx array,
2359 * (pic16_freeAsmop): remove the freed register from the
2360 _G.sregsAlloc field,
2361 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2362 a compare of 'WREG',
2363 * (pic16_popGetTempRegCond): changed function prototype, now
2364 function takes also a bitVector argument v which holds the current
2365 set of registers that are allocated for stack access by aopForSym,
2366 registers allocated in aopForSym for accessing stack symbols are not
2367 any more part of the functions usedRegs field,
2368 * (genCall): some times aopOp is called for a stack variable to be
2369 send, aopForSym might perform the push, if this is true make sure
2370 that genCall doesn't push the variable twice by testing _G.resDirect,
2371 * (genFunction): changed testing for unspecified interrupt number
2372 from 256 to INTNO_UNSPEC,
2373 * modified selection scheme of frame pointer generation. Previously
2374 if function did use local registers a frame pointer was generated,
2375 now a frame pointer is generated only if function has arguments
2376 (that need PLUSW2 register access), or has stack arguments, or the
2377 compiler is not instructed to omit the frame pointer,
2378 * (genEndFunction): before restoring local registers that were saved
2379 in the function preamble, also restore the registers that *might*
2380 have been allocated for stack access,
2381 * (genRet): removed some old comments,
2382 * (genCmp, the active (RN's) version): added a call to the
2383 pic16_genCmp_special function to perform the compare with a more
2384 robust and optimized way,
2385 * (genInline): a feature has been added in inline code generation,
2386 which allows a wildcard variable substitution when writing inline
2387 assembly. Code is incomplete and experimental therefore undocumented,
2388 * (genCast): changed order of aopOp for result and right to allow
2389 aopForSym to directly load the result if possible,
2390 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2391 perform an optimized compare on some selected special occasions,
2392 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2393 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2394 generate an IVT any more,
2395 * src/pic16/main.c (pic16_optionsTable): added command line option
2397 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2398 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2400 * src/pic16/NOTES: Raphael Neider added in list of active developers
2401 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2402 jumptable_end to prevent bug #,
2403 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2404 inCond and outCond fields,
2405 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2406 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2407 turn off register spilling,
2408 * (packRegsForOneUse): synced with other ports' versions although it
2409 is not used currently,
2410 * (pic16_packRegisters): added an optimization while reading
2411 structure bitfields, some registers may be saved (malloc code is
2412 decreased by 80 bytes)
2414 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2416 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2417 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2418 this can be optimized more?
2420 2005-03-10 Raphael Neider <rneider AT web.de>
2422 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2423 genNearPointerGet): (hopefully) fixed access to bitfields via
2424 pointers (p->bitN = x; and x = p->bitN; failed)
2426 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3041 (setFromConditionArgs): friendly operand parser for peephole rules,
3042 (operandBaseName, operandsNotRelated): new peephole condition
3043 "operandsNotRelated" -- similar to "operandsNotSame", but takes

3056 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3058 Adding support for replacing ljmps with sjmps in jumptables
3059 generated for switch statements. For now you need to set the
3060 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3061 Now 4 algorithms for mcs51 jumptable generation are used:
3062 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3063 addresses loaded pc-relative for up to 112 cases and stack-pushing
3064 target addresses loaded with offset from dptr for up to 256 cases.

3090 Large cummulative patch for pic16 port.
3091 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3092 to call when a stack overflow occurs,
3093 * (malloc.h): added CVS Id tag,
3094 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3096 * added libc directory. The current version of LibC contains string
3097 functions, ctype functions and macros and some functions of the
3098 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3099 be extensively tested in the future. Standard disclaimer here.
3100 Library is not automatically build yet. But one can build it by
3101 invoking 'make' inside the libc directory.
3102 * added ADC library under libio. Preliminary version yet.
3104 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3111 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3112 * (pic16_storeForReturn): optimized return of 0,
3113 * (genCmp): experimental code for new genCmp which uses PIC18's
3114 special compare&skip instructions. Initial tests fail some times
3115 with variables grater than 1 byte in size, so new code is disabled,
3116 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3118 * (genCast): began a fix to optimize the casting of a bit to another
3119 bit, now assigning a bitfield to another bitfield will fail, sorry,
3120 * src/pic16/main.c: disabled the use of lr-support feature,
3121 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3122 * added some function prototypes, added function _debugf prototype,

3124 bits with offset (case PO_GPR_BIT),
3125 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3127 * (isBankInstruction): modified to return 0 for no banking instruction,
3128 and 1 for banking instruction,
3129 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3130 caused stop processing pCodes after a inline assembly block,
3131 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3132 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3133 registers when it shouldn't,
3134 * src/pic16/ralloc.c (allocReg): add preliminary support for
3135 supporting a limited set of temporary registers,
3137 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3139 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3140 genDataPointerSet): ensure assignments always copy in MSB to LSB
3142 (loadRegFromAop): recognize CLRH optimization,
3143 (genFunction): optimize RECEIVE iCodes in reentrant functions
3145 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3147 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3148 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3150 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3161 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3163 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6142 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6144 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6145 loaded with the linker search paths (-L arguments) and the libraries
6146 to be linked with the current source (-l arguments). Changes
6147 currently will affect only the pic16 port.
6148 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6149 include path the port specific paths and port specific libraries,
6150 * gplink command now contains the $3 argument,
6151 * src/pic16/device.h,
6152 * src/pic16/device.c,: structure PIC_device is made public and
6153 renamed to PIC16_device, the same for variable Pics which is renamed
6154 to Pics16. Updated all references to them.
6155 * src/pic16/glue.c (pic16glue): corrected bug with code
6156 initialization which bypassed the variable initializations block.

6166 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6168 Documenting changes from previous commits.
6169 * configure.in (version 1.56),
6170 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6171 when generating output files to configure the pic16 library,
6172 but now I've commented it out, since gputils aren't installed in the
6173 SF compile farm, so library won't compile
6175 * device/lib/Makefile.in (version 1.56): initially I've added in
6176 target 'all' the prerequestive 'model-pic16' so it compiled the
6177 pic16 library, but now I've commented it out for the same reasons
6179 * added targets 'model-pic16' and 'objects-pic16' to compile the
6181 * added target 'port-specific-objects-pic16' to handle the
6182 generated libraries and copy them into the build/ directory
6183 * added target 'clean-intermediate-pic16' to clean intermediate
6184 files into pic16 directory
6185 * in target 'installdirs' added line to create directory pic16 in
6186 the installation path
6188 * device/include/Makefile.in (version 1.11): in target 'install'
6189 added lines to copy all header files to installation path,
6190 * in target 'installdirs' added line create directory for pic16
6191 headers in the installation path
6193 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6206 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6207 option so that it actually works. Made it specific to the z80, since
6208 the gbz80 doesn't have these kinds of I/O ports.
6210 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6212 * device/include/z180.h,

6225 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6227 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6228 changed interrupt vector table generation to only emit declared vectors.
6229 * device/include/Makefile.in: added missing backslash
6230 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
6232 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6234 Mainly changes to support compilation of the device libraries
6235 * src/pic16/device.c: stack is allocated via symbol and not
6236 via literal number. The symbol is placed in the corresponding
6237 position of the data ram
6238 * (pic16_dump_section): relocatable and absolute uninitialized
6239 data are now emitted in sorted order to reduce section naming,
6240 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6241 weren't marked as being in the access bank,
6243 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6245 Added portion of GNU PIC Library under the directory
6246 device/include/pic16 and device/lib/pic16. These files
6247 contain the declarations of SFRs for the PIC18Fxx2 devices.
6248 The directory is initialized via configure from toplevel.
6250 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6252 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6253 the spilllocations to be compared correctly
6255 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6257 * src/SDCCast.c (decorateType): fixed bug introduced today
6259 2004-01-12 Borut Razem <borut.razem AT siol.net>
6261 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

6264 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6266 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6267 in simpler and even better code
6269 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
6271 * src/SDCCicode.c (operandOperation): fixed bug #874819

6275 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6277 * doc/sdccman.lyx: Moved and added some sections, small changes
6278 all over. Telling LaTeX to be less strict with word spacing
6279 to better keep the right margin. Changed some notes about
6280 maintainance of the ports in section 3.2.1 - is it OK like this?
6282 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6284 SDCC source changes:
6285 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6318 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
6319 UPPER for immediate operands,
6320 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6322 * src/pic16/peeph.def: all peepholes with movff are commented out,
6323 because there is a problem in the pcode peep optimizer,
6324 * src/pic16/ralloc.c: the register allocator can now reuse local
6325 function symbols for another function. This saves register usage.
6326 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6328 Added file src/pic16/NOTES with information about program writing on
6329 the current port version.

6338 * src/SDCCmain.c : fixed #872250: -l command line defined library
6339 files are scanned before standard library files
6341 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6358 gen51Code): more efficient parameter receive for --model-large
6361 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6364 * src/z80/main.c: added missed needLinkerScript flags (more than
6365 one port structure defined in these file)
6366 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
6369 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

6382 needLinkerScript flag
6384 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6385 * src/pic/glue.c: added variable udata_section_name to
6386 override default uninitialized data segment definition for
6387 devices only with SHAREBANK memory (reported from Erik Epetrich)
6388 * (pic14emitOverlay): modified to emit a commented overlay segment
6389 directive when no overlay data exist
6390 * (picglue): modified to emit uninitialized data segment
6391 according to udata_section_name
6392 * src/pic/main.c (_pic14_parseOptions): added command line

6396 arguments via -W option
6397 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6398 object file from '.rel' to '.o' in port->linker structure,
6399 changed size of fptr from 2 to 3 in port structure
6401 2004-01-07 Borut Razem <borut.razem AT siol.net>
6403 * support/scripts/sdcc.nsi: update PATH
6404 * support/scripts/sdcc.ico: craeted
6406 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6408 * device/include/Makefile.in: fix install
6409 * doc/Makefile: fix install
6411 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6413 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6415 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
6416 how the function variable allocation summary is displayed; also
6417 include information about variables allocated to the overlay
6420 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6422 * as/mcs51/lkmain.c: Help about -Y option

6432 LEFT_OP (left shift)
6434 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6436 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6437 (default behaviour).
6439 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6441 A python script to validate compiler diagnostic messages. It can be
6442 used to verify that sdcc complains about bad c source code and
6443 gives a good location of the error.
6444 * support/valdiag/Makefile,
6445 * support/valdiag/valdiag.py,
6446 * support/valdiag/tests/*
6448 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6450 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6451 * src/SDCCsymt.c (newEnumType),

6459 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6461 * src/common.h: added ifndef/define/endif macros
6462 around the header file.
6463 Bug reported from Jesus Calvino-Fraga
6465 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6467 * sdcc.spec: updated
6468 * device/include/Makefile.in: don't install CVS directories
6469 * device/lib/Makefile.in: added removal of CVS directories after install
6470 * doc/Makefile: fixed install, added local_icons
6471 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6472 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6473 * src/ds390/gen.c (genRightShift): fixed bug #870788
6474 * src/SDCCast.c (decorateType): fixed bug #870781
6476 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6478 PIC16 port related changes:
6479 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6480 added variable stackPos,
6482 * gen.c: genCall, assignResultValue: added support for
6483 pushing/retrieving function parameters to/from stack,
6484 genFunction,genEndFunction: setup stack frame for the
6486 genAddrOf: will be changed according to bug 863624
6488 * added files genutils.c and genutils.h which contain gen*
6489 debugged and optimised functions extracted from gen.c
6491 * glue.c: added variable 'externs' which holds extern symbols,
6492 pic16emitRegularMap: is modified to properly handle relocatable
6493 symbols under the new scheme,
6494 pic16createInterruptVect: is modified
6495 pic16printPublics: is modified to emit 'global' assembler directives,
6496 added pic16_printExterns to print extern symbols,
6497 pic16glue: initializes stack/frame pointer in the beginning of
6498 the assembly output. Temporary hack, will be corrected later,
6499 because gplink yet does not support stack and SDCC does not
6500 yet support a type of crt0.o object to create the final binary.
6502 * Removed many lines that contain 8051 legacy code.
6503 * The code is finally placed under a 'code' directive.
6504 * Added port specific options.
6506 * _process_pragma: simplified since now we do not need *special*
6507 include file to define SFR registers. But a separate header
6508 will be needed. This will be developed later.
6509 * _pic16_parseOptions: added, parses port specific options:
6510 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6511 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6512 --preplace-udata-with=
6514 * _pic16_setDefaultOptions: modified to initialize section names,
6515 but hack is temporarly out of order since it needs improvement.
6516 * _pic16_genAssemblerPreamble: configuration words are emitted by
6517 their address instead of their name. This part is incomplete and
6518 supports only the 18Fxx2 devices. Other devices will emit an error
6519 during assembly since they do not contain the same set of config
6521 * _pic16_genIVT: is modified,
6523 * pcode.c: added definitions for some hardware registers that are needed
6525 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6526 All PCI entries are updated. Now LFSR is supported.
6527 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6528 * added pic16_newpCodeOpLit2 to support instructions with
6529 two literal arguments
6530 * pic16_pCode2str: corrected code that emits assembler instructions
6531 with two literal operands and those that have an access bit modifier
6532 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6533 this fixes a bug which caused some labels to be lost, when an
6534 assembler directive was added, i.e. banksel,
6535 * pic16_FixRegisterBanking: improved logic that causes the insertion
6537 * InlineFunction: functions that are called once, are not any more
6538 inlined. This can be a port option in the future,
6540 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6542 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6543 hold the corresponding uninitialized symbols,
6544 * pic16_allocProcessorRegister: registers have explicit marked the
6546 * pic16_allocInternalRegister: registers are explicit marked as
6548 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6549 processing list, so bit registers were lost,
6552 * ralloc.h: added field 'accessBank' and original symbol operand
6553 in register definition,
6554 * removed the field isMapped from register definition,
6556 ** Several functions have been removed from various sources:
6557 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6558 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6559 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6560 pic16_assignRelocatableRegisters
6562 ** others have been introduced:
6563 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6564 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6566 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6568 * support/scripts/inc2h.pl: changed definition of BIT_AT
6569 to emit 'sbit at' instead of 'bit at'. This was a request.
6571 PIC16 port related preliminary changes:
6572 * gen.c: prefixed function popRegFromString with
6573 pic16_ and all references to it corrected
6574 * pcode.c: all pic16_pc_* hardware registers prefixed
6575 with underscore (_),
6576 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6577 * ralloc.c: newReg(): when register is REG_SFR then
6578 set address to rIdx,
6579 pic16_allocProcessorRegister(): marks register wasUsed=0
6580 pic16_writeUsedRegs(): added a call to assign processor
6581 registers via pic16_assignFixedRegisters
6583 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6585 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6586 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6587 variables in unused register banks. Also the SSEG is placed
6588 wherever there is enough space for it, and IDATA can be anywhere
6589 in internal RAM. For now compile using -Wl-Y[stack_size].
6590 The mem file is different for this option as well, since it
6591 makes no sense of talking about DSEG lenght.
6593 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6595 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6596 in certain cases, e.g. when ROM assignment, patch provided
6597 from Albert den Haan.
6599 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
6601 Many signedness and type propagation fixes:
6602 * src/SDCCicode.c: made geniCodeCast() static
6603 replaced SPEC_ by IS_ (cosmetic)
6604 (operandOperation): fixed div and mod operation
6605 (usualBinaryConversions): added support for promotion of char
6606 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
6607 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
6608 (geniCodeAdd): an array index will stay unsigned, even if promoted

7605 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7606 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7607 If they pop r0/r1 they must be called in the opposite order than aopOp().
7608 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7609 (resp. --stack-auto), prepared for --xstack

7618 these ports have their own __sdcc_external_start()
7620 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7622 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7623 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7624 type for bits was changed. It resulted in bit variables becoming
7625 global, which is not permitted in PIC 14 assembly output.
7627 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7629 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7631 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7633 Z80 and MCS51 linkers complaint if a public symbol is defined
7634 in more than one library module:

7642 A few small changes that speed up the peephole optimizer.
7646 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7648 Try to make the peephole optimizer smarter by maintaining
7649 an association between the assembly source code and the
7650 iCodes that originated them. Put this information to use
7651 with a new peephole rule condition "notVolatile" so that
7652 the rules can be aggressive yet still safe.
7657 * src/mcs51/peeph.def
7659 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7663 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7664 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7665 if the left or right operand symbols have the accuse flag set.
7667 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7669 Changed the type of the result of the ! (NOT) operator to char;
7670 previously it returned the same type as the source. This allows
7671 us to eliminate all the genFloatNot functions (all of its target
7672 implementations were very buggy) since !float can use the same
7675 * src/SDCCicode.c (ast2iCode): ! returns char

7677 * src/ds390/gen.c (genNot, genNotFloat),
7678 * src/z80/gen.c (genNot, genNotFloat),
7679 * src/pic/gen.c (genNot, genNotFloat),
7680 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7684 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7685 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7686 during interrupts. Ensure WSAVE is located at a shared bank address.
7687 2. Fixed page selection in some places
7688 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7689 the registers name strings.
7690 4. Fixed "signed / unsigned compare" compiler warnings.
7691 5. The PIC port manages its own allocation of the general purpose
7692 registers, but makes no attempt to reuse them. As a result when
7693 compiling it soon runs out of general purpose registers. Some
7694 additional code was added to the files pcode.c and device.c to walk
7695 through the function call tree and rename the registers so that they
7705 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7712 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7714 Made bitfield a distinct type from bit so that bitfields
7715 convert as per ANSI C and bits retain their traditional
7716 boolean style behaviour. Implemented bitfield support in
7724 * src/ds390/gen.c: bit v bitfield split
7725 * src/z80/gen.c: New support for bitfields
7726 * support/regression/tests/bitfields.c: reenabled z80,
7729 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7731 Rules 246.x, 247.x relate to bitfields, the others speed up
7732 access to xdata mapped I/O devices.
7734 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7736 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7738 Cleaned up genPackBits and genUnpackBits and added two helper
7739 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7740 for literal assignments in genPackBits (thanks to Frieder for
7746 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7748 Fixed bug #748310 (pointer to function type mishandled when the
7749 function name is omitted). Also fixed a SIGSEGV when a function
7750 attribute (reentrant, etc) is used on a non-function or on a
7751 function but misplaced before the parameter list.
7753 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7755 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7778 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7780 Made the constant following the "interrupt" keyword optional. If
7781 omitted, the function will not automatically be given an entry
7782 in the interrupt vector table (similar to #pragma NOIV, but
7783 less syntacticly kludgy). The interrupt number is also now
7784 range checked. Also fixed a bug in the high order bit example

7800 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7802 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7803 be re-activated by defining REDUCE_LITERALS)
7804 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7805 unsigned, but are signed by default
7806 * src/SDCCval.c (constVal): rearranged
7807 * src/SDCCval.c (valMod): preliminary fix
7808 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8260 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8261 the regression tests I'm not brave enough to enable 245.b, 245.c
8262 * doc/sdccman.lyx: added latex preamble for hyperref package.
8263 Using pdflatex this will give you a hyperlinked pdf file with
8264 bookmarks. (prepend '%' before /usepackage if this breaks something)

8278 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
8280 Applied patch from bug 737905 (renamed yylineo to mylineno):
8287 * src/pic16/pcode.c: Cleaned warnings
8288 * src/pic16/pcodeflow.c: Cleaned warnings
8289 * src/pic16/pcoderegs.c: Cleaned warnings

8302 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8304 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8305 it can be defined with CFLAGS when running configure
8306 * src/SDCCmain.c: fixed compiling + linking with object files
8308 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8310 * configure.in: configure for pic16 port,
8311 added --disable-pic16-port
8312 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8313 * src/SDCCmain.c: linkOptions is changed to set *,
8314 added if/endif conditional macros to remove options help
8315 messages from optionsTable when a port is not configured, added
8316 support for the PIc16 port in the ports table, when executing
8317 the compiler with no port specified on command line, a default
8318 port is selected with the new macro DEFAULT_PORT which is
8319 defined in port.h, in setDefaultOptions() linkOptions is removed
8320 from initialization assignment, since now it is a set,
8321 parseCmdLine uses setParseWithComma for linkOptions, in
8322 linkEdit() linkOptions are accessed with new function indexSet()
8323 which returns the i'th item of a set variable. See SDCCset.c, in
8324 linkEdit() when calling buildCmdLine(), added linkOptions as
8325 last argument. Now users can pass arguments to gplink via the
8326 -Wl option, main() uses pic16glue() to glue up pic16 programs
8327 * src/SDCCpeeph.c: various changes to support pic16

8336 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8338 * src/pic16/glue.c: commented out some error producing lines
8339 * src/pic16/main.c: __config directives are commented out to stop
8340 gpasm complaining and test the linkage with gplink, _linkCmd and
8341 _asmCmd changed to be more gplink and gpasm friendly
8342 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8343 produced an error when parsed, peep rule 12 is added to utilize
8344 movff, but it is commented out since the pCode does not support
8345 yet a command with 2 address arguments
8347 2003-05-18 <johan AT balder>
8349 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8350 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8351 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

8369 on entry now. Add tbreak. Other enhancements and fixes for use
8372 2003-05-12 Borut Razem <borut.razem AT siol.net>
8374 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8376 2003-05-11 Borut Razem <borut.razem AT siol.net>
8378 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8379 the path of bin directory, so that PATH is the only env. variable, which has to be set
8380 in case of standard installation.
8381 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9410 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9412 * in \sdcc\as\mcs51\ changed these files in order to create an
9413 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9414 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9415 following files to include the previous two files: aslink.dsp,
9416 Makefile.aslink, Makefile.bcc, and Makefile.in.
9418 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9419 .adb instead of .cdb
9421 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9423 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9424 value from option --iram-size.
9426 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9428 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9431 2002-09-18 <wiml AT hhhh.org>
9433 * SDCClrange.h: exposed setFromRange() and setToRange()
9434 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9435 packRegsForAccUse() (bug 542397)
9436 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9437 multiple times and emitting the fetch operations more than once
9438 added aopGetUsesAcc() function to allow binary operators to
9439 fetch their operands in the correct order; made genMinus() emit
9440 compact code for X = LITERAL - Y
9442 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9443 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9444 sprintf() in line 1267.
9446 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9447 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9450 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9451 Changes to aslink (All the changes are marked with 'JCF'):
9453 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9456 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9457 area BSEG. Also moves, if possible, the DATA area down into the internal
9458 ram so more space is available.
9460 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9463 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9464 not bytes. Function summary() which creates a memory usage summary
9465 file with extension .mem. Reports of overlaping stack and small stack
9466 size. If the space for the stack is less than 16 bytes aslink trows a
9469 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9470 the 8051. Option 'y' for memory summary output file.
9472 Changes to sdcc (All the changes are marked with 'JCF'):
9474 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9476 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9477 overlaying area for it (uses RegBankUsed[4]).
9479 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9480 bank zero as used by default. By default aslink locates the stack
9481 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9482 the creation of the .mem file. Delegates the allocation of data area
9483 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9484 the begining of the stack area to aslink.
9486 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9487 glue() in SDCCglue.c creates an area for it.
9489 2002-09-03 Borut Razem <borut.razem AT siol.net>
9490 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9491 sdcc/src/pic/glue.c:
9492 introduced atexit() handler for teporay files removal in case of
9493 errors, assertions, ...
9495 2002-08-29 Borut Razem <borut.razem AT siol.net>
9496 * sdcc/support/cpp2/auto-host_vc_in.h:
9497 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9498 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9499 Maybe there is a similar problem with BORLANDC? It should be checked!
9501 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9502 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9503 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9504 was not executed, and the compiler (cl) launched a warning:
9505 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9507 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9508 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9510 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

9517 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9518 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9519 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9520 - added Release configuration in VS projects
9521 - review of compiler an linker options
9522 - VC .exe files are generated in bin_vc directory, not to interfere
9523 with binaries generated from other projects (cygwin, mingw, bcc ...)
9525 * sdcc/src/yacc.dsp: added
9527 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9528 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9529 and insert the version number definitions from .version
9531 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9533 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9537 removed from CVS, generated automatically
9539 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9540 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9542 2002-08-11 Borut Razem <borut.razem AT siol.net>
9543 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9545 2002-08-10 Borut Razem <borut.razem AT siol.net>
9546 * src/SDCCmain.c (main):
9547 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9548 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9549 The consequence was that some temporary files were not removed.
9552 unification of code in functions tempfilename() and tempfile():
9553 function tempnam() is defined in Visual Studio 6.0 and .NET
9555 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9557 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9558 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9559 - removed compiler command line option /WX: Treats all warnings as errors
9560 - update a list of source files, included into the project
9562 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9563 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9564 changed project type to Generic Project so that can be correcly converted to VS.NET project
9566 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9568 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9572 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9573 added return 0 statements after assert() to make compiler happy
9575 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9576 added newline in the def file to keep MSC compiler satisfied
9578 * sdcc/src/z80/gen.c:
9579 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9580 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9581 - solved MSC error in function aopDump()
9583 * sdcc_vc.h: define PREFIX as "\\sdcc"
9585 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9637 Initialized the new field char *Processor field to NULL in all ports
9640 Compiler generated registers for interrupt context saving
9641 were not getting allocated.
9643 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9646 Fixed left shift. Will promote the left side of a left shift
9647 if a) left shifting more than size of operand or b) when assigned
9648 to something size > size of left side
9650 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9760 * sdcc/src/SDCCloop.c:
9761 Previous fix was not good. basic blocks that have "break" or "return" are
9762 not really partof a loop , but live ranges used in these blocks should
9763 be live thru the entire loop, so set partOfLoop but don't add them to
9766 2002-02-21 <johan AT FRIJA>
9768 * src/SDCCcse.c: fixed bug #514308
9770 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
