2179 on rIfx (genCmp was broken)
2181 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2183 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
2184 * src/z80/main.c (_keywords[]),
2185 * src/SDCCglobal.h (struct options),
2187 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2188 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2189 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2190 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2191 always available in leading double underscore form. The C99 support is
2192 mostly missing, but it's a start.
2193 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2194 reserved identifier "__data".
2196 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2240 immedDom() returning wrong block; probably fixes bug #1160833)
2242 2005-03-20 Borut Razem <borut.razem AT siol.net>
2244 * support/scripts/inc2h.pl: WIN32 port

2272 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2274 * device/lib/printf_large.c: removed inline assembly for portability and
2275 readability. Use printf_fast if speed or size are more important.
2276 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2277 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2279 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2281 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2282 prevent compiler warning
2284 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2286 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2287 moved to level 0 and declared as static. Also they are explicit
2288 placed in access bank. This was necessery because some times they
2289 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2290 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2291 optimizations. Currently only compare to unsigned char is implemented,
2292 * src/pic16/gen.c: added fReturnIdx array,
2293 * (struct resolvedIfx) is moved to gen.h and made public,
2294 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2295 * (aopForSym): added an optimization to directly store in stack of
2296 the operand of a SEND iCode,
2297 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2298 but as registers instead (AOP_REG) using the fReturnIdx array,
2299 * (pic16_freeAsmop): remove the freed register from the
2300 _G.sregsAlloc field,
2301 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2302 a compare of 'WREG',
2303 * (pic16_popGetTempRegCond): changed function prototype, now
2304 function takes also a bitVector argument v which holds the current
2305 set of registers that are allocated for stack access by aopForSym,
2306 registers allocated in aopForSym for accessing stack symbols are not
2307 any more part of the functions usedRegs field,
2308 * (genCall): some times aopOp is called for a stack variable to be
2309 send, aopForSym might perform the push, if this is true make sure
2310 that genCall doesn't push the variable twice by testing _G.resDirect,
2311 * (genFunction): changed testing for unspecified interrupt number
2312 from 256 to INTNO_UNSPEC,
2313 * modified selection scheme of frame pointer generation. Previously
2314 if function did use local registers a frame pointer was generated,
2315 now a frame pointer is generated only if function has arguments
2316 (that need PLUSW2 register access), or has stack arguments, or the
2317 compiler is not instructed to omit the frame pointer,
2318 * (genEndFunction): before restoring local registers that were saved
2319 in the function preamble, also restore the registers that *might*
2320 have been allocated for stack access,
2321 * (genRet): removed some old comments,
2322 * (genCmp, the active (RN's) version): added a call to the
2323 pic16_genCmp_special function to perform the compare with a more
2324 robust and optimized way,
2325 * (genInline): a feature has been added in inline code generation,
2326 which allows a wildcard variable substitution when writing inline
2327 assembly. Code is incomplete and experimental therefore undocumented,
2328 * (genCast): changed order of aopOp for result and right to allow
2329 aopForSym to directly load the result if possible,
2330 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2331 perform an optimized compare on some selected special occasions,
2332 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2333 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2334 generate an IVT any more,
2335 * src/pic16/main.c (pic16_optionsTable): added command line option
2337 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2338 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2340 * src/pic16/NOTES: Raphael Neider added in list of active developers
2341 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2342 jumptable_end to prevent bug #,
2343 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2344 inCond and outCond fields,
2345 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2346 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2347 turn off register spilling,
2348 * (packRegsForOneUse): synced with other ports' versions although it
2349 is not used currently,
2350 * (pic16_packRegisters): added an optimization while reading
2351 structure bitfields, some registers may be saved (malloc code is
2352 decreased by 80 bytes)
2354 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2356 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2357 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2358 this can be optimized more?
2360 2005-03-10 Raphael Neider <rneider AT web.de>
2362 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2363 genNearPointerGet): (hopefully) fixed access to bitfields via
2364 pointers (p->bitN = x; and x = p->bitN; failed)
2366 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2553 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2554 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2555 this might fix SIGSEGVs on MinGW...
2556 * src/SDCCopt.c (killDeadCode): restored original behaviour
2557 (volatile operands might get thrown away though)
2559 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2561 * src/pic16/gen.c: fixed bug #1106975,

3031 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3032 to call when a stack overflow occurs,
3033 * (malloc.h): added CVS Id tag,
3034 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3036 * added libc directory. The current version of LibC contains string
3037 functions, ctype functions and macros and some functions of the
3038 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3039 be extensively tested in the future. Standard disclaimer here.
3040 Library is not automatically build yet. But one can build it by
3041 invoking 'make' inside the libc directory.
3042 * added ADC library under libio. Preliminary version yet.
3044 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3045 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3046 aopForRemat() now and not by pic16_aopOp(),
3047 * (pic16_popGetTempReg): removed warning messgae when allocating
3048 temporary registers, its a buggy feature and will be removed,
3049 * (pic16_popGet): set register instance field in AOP_CRY,
3050 * (pic16_outBitC): fixed for results in size greater than 1,
3051 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3052 * (pic16_storeForReturn): optimized return of 0,
3053 * (genCmp): experimental code for new genCmp which uses PIC18's
3054 special compare&skip instructions. Initial tests fail some times
3055 with variables grater than 1 byte in size, so new code is disabled,
3056 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3058 * (genCast): began a fix to optimize the casting of a bit to another
3059 bit, now assigning a bitfield to another bitfield will fail, sorry,
3060 * src/pic16/main.c: disabled the use of lr-support feature,
3061 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3062 * added some function prototypes, added function _debugf prototype,
3063 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3064 bits with offset (case PO_GPR_BIT),
3065 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3067 * (isBankInstruction): modified to return 0 for no banking instruction,
3068 and 1 for banking instruction,
3069 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3070 caused stop processing pCodes after a inline assembly block,
3071 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3072 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3073 registers when it shouldn't,
3074 * src/pic16/ralloc.c (allocReg): add preliminary support for
3075 supporting a limited set of temporary registers,
3077 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3079 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3080 genDataPointerSet): ensure assignments always copy in MSB to LSB
3082 (loadRegFromAop): recognize CLRH optimization,
3083 (genFunction): optimize RECEIVE iCodes in reentrant functions
3085 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3087 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3088 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3090 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
3091 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
3092 contiguous with data
3094 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3096 * device/lib/_gptrget.c (_gptrget),
3097 * device/lib/_gptrgetc.c (_gptrgetc),
3098 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
3099 instead of sjmp to ret
3100 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3101 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3103 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6082 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6084 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6085 loaded with the linker search paths (-L arguments) and the libraries
6086 to be linked with the current source (-l arguments). Changes
6087 currently will affect only the pic16 port.
6088 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6089 include path the port specific paths and port specific libraries,
6090 * gplink command now contains the $3 argument,
6091 * src/pic16/device.h,
6092 * src/pic16/device.c,: structure PIC_device is made public and
6093 renamed to PIC16_device, the same for variable Pics which is renamed

6108 Documenting changes from previous commits.
6109 * configure.in (version 1.56),
6110 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6111 when generating output files to configure the pic16 library,
6112 but now I've commented it out, since gputils aren't installed in the
6113 SF compile farm, so library won't compile
6115 * device/lib/Makefile.in (version 1.56): initially I've added in
6116 target 'all' the prerequestive 'model-pic16' so it compiled the
6117 pic16 library, but now I've commented it out for the same reasons
6119 * added targets 'model-pic16' and 'objects-pic16' to compile the
6121 * added target 'port-specific-objects-pic16' to handle the
6122 generated libraries and copy them into the build/ directory
6123 * added target 'clean-intermediate-pic16' to clean intermediate
6124 files into pic16 directory
6125 * in target 'installdirs' added line to create directory pic16 in
6126 the installation path

6176 via literal number. The symbol is placed in the corresponding
6177 position of the data ram
6178 * (pic16_dump_section): relocatable and absolute uninitialized
6179 data are now emitted in sorted order to reduce section naming,
6180 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6181 weren't marked as being in the access bank,
6183 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6185 Added portion of GNU PIC Library under the directory
6186 device/include/pic16 and device/lib/pic16. These files
6187 contain the declarations of SFRs for the PIC18Fxx2 devices.
6188 The directory is initialized via configure from toplevel.
6190 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6192 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6218 all over. Telling LaTeX to be less strict with word spacing
6219 to better keep the right margin. Changed some notes about
6220 maintainance of the ports in section 3.2.1 - is it OK like this?
6222 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6262 * src/pic16/peeph.def: all peepholes with movff are commented out,
6263 because there is a problem in the pcode peep optimizer,
6264 * src/pic16/ralloc.c: the register allocator can now reuse local

6301 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6304 * src/z80/main.c: added missed needLinkerScript flags (more than
6305 one port structure defined in these file)
6306 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6357 include information about variables allocated to the overlay
6360 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6362 * as/mcs51/lkmain.c: Help about -Y option

6374 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6376 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6377 (default behaviour).
6379 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6381 A python script to validate compiler diagnostic messages. It can be
6382 used to verify that sdcc complains about bad c source code and
6383 gives a good location of the error.
6384 * support/valdiag/Makefile,
6385 * support/valdiag/valdiag.py,
6386 * support/valdiag/tests/*
6388 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6390 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6401 * src/common.h: added ifndef/define/endif macros
6402 around the header file.
6403 Bug reported from Jesus Calvino-Fraga
6405 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6407 * sdcc.spec: updated
6408 * device/include/Makefile.in: don't install CVS directories
6409 * device/lib/Makefile.in: added removal of CVS directories after install
6410 * doc/Makefile: fixed install, added local_icons
6411 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6412 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6413 * src/ds390/gen.c (genRightShift): fixed bug #870788
6414 * src/SDCCast.c (decorateType): fixed bug #870781
6416 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6418 PIC16 port related changes:
6419 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6420 added variable stackPos,
6422 * gen.c: genCall, assignResultValue: added support for
6423 pushing/retrieving function parameters to/from stack,
6424 genFunction,genEndFunction: setup stack frame for the
6426 genAddrOf: will be changed according to bug 863624
6428 * added files genutils.c and genutils.h which contain gen*
6429 debugged and optimised functions extracted from gen.c
6431 * glue.c: added variable 'externs' which holds extern symbols,
6432 pic16emitRegularMap: is modified to properly handle relocatable
6433 symbols under the new scheme,
6434 pic16createInterruptVect: is modified
6435 pic16printPublics: is modified to emit 'global' assembler directives,
6436 added pic16_printExterns to print extern symbols,
6437 pic16glue: initializes stack/frame pointer in the beginning of
6438 the assembly output. Temporary hack, will be corrected later,
6439 because gplink yet does not support stack and SDCC does not
6440 yet support a type of crt0.o object to create the final binary.
6442 * Removed many lines that contain 8051 legacy code.
6443 * The code is finally placed under a 'code' directive.
6444 * Added port specific options.
6446 * _process_pragma: simplified since now we do not need *special*
6447 include file to define SFR registers. But a separate header
6448 will be needed. This will be developed later.
6449 * _pic16_parseOptions: added, parses port specific options:
6450 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6451 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6452 --preplace-udata-with=
6454 * _pic16_setDefaultOptions: modified to initialize section names,
6455 but hack is temporarly out of order since it needs improvement.
6456 * _pic16_genAssemblerPreamble: configuration words are emitted by
6457 their address instead of their name. This part is incomplete and
6458 supports only the 18Fxx2 devices. Other devices will emit an error
6459 during assembly since they do not contain the same set of config
6461 * _pic16_genIVT: is modified,
6463 * pcode.c: added definitions for some hardware registers that are needed
6465 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6466 All PCI entries are updated. Now LFSR is supported.
6467 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6468 * added pic16_newpCodeOpLit2 to support instructions with
6469 two literal arguments
6470 * pic16_pCode2str: corrected code that emits assembler instructions
6471 with two literal operands and those that have an access bit modifier
6472 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6473 this fixes a bug which caused some labels to be lost, when an
6474 assembler directive was added, i.e. banksel,
6475 * pic16_FixRegisterBanking: improved logic that causes the insertion
6477 * InlineFunction: functions that are called once, are not any more
6478 inlined. This can be a port option in the future,
6480 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6482 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6483 hold the corresponding uninitialized symbols,
6484 * pic16_allocProcessorRegister: registers have explicit marked the
6486 * pic16_allocInternalRegister: registers are explicit marked as
6488 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6489 processing list, so bit registers were lost,
6492 * ralloc.h: added field 'accessBank' and original symbol operand
6493 in register definition,
6494 * removed the field isMapped from register definition,
6496 ** Several functions have been removed from various sources:
6497 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6498 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6499 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6500 pic16_assignRelocatableRegisters
6502 ** others have been introduced:
6503 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6504 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6506 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6508 * support/scripts/inc2h.pl: changed definition of BIT_AT
6509 to emit 'sbit at' instead of 'bit at'. This was a request.
6511 PIC16 port related preliminary changes:
6512 * gen.c: prefixed function popRegFromString with
6513 pic16_ and all references to it corrected
6514 * pcode.c: all pic16_pc_* hardware registers prefixed
6515 with underscore (_),
6516 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6517 * ralloc.c: newReg(): when register is REG_SFR then
6518 set address to rIdx,
6519 pic16_allocProcessorRegister(): marks register wasUsed=0
6520 pic16_writeUsedRegs(): added a call to assign processor
6521 registers via pic16_assignFixedRegisters
6523 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6525 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6526 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6527 variables in unused register banks. Also the SSEG is placed
6528 wherever there is enough space for it, and IDATA can be anywhere
6529 in internal RAM. For now compile using -Wl-Y[stack_size].
6530 The mem file is different for this option as well, since it
6531 makes no sense of talking about DSEG lenght.
6533 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6535 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6536 in certain cases, e.g. when ROM assignment, patch provided
6537 from Albert den Haan.
6539 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7562 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7563 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7582 A few small changes that speed up the peephole optimizer.
7586 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7588 Try to make the peephole optimizer smarter by maintaining
7589 an association between the assembly source code and the
7590 iCodes that originated them. Put this information to use
7591 with a new peephole rule condition "notVolatile" so that
7592 the rules can be aggressive yet still safe.
7597 * src/mcs51/peeph.def
7599 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7603 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7605 if the left or right operand symbols have the accuse flag set.
7607 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7609 Changed the type of the result of the ! (NOT) operator to char;
7610 previously it returned the same type as the source. This allows
7611 us to eliminate all the genFloatNot functions (all of its target
7612 implementations were very buggy) since !float can use the same
7615 * src/SDCCicode.c (ast2iCode): ! returns char

7617 * src/ds390/gen.c (genNot, genNotFloat),
7618 * src/z80/gen.c (genNot, genNotFloat),
7619 * src/pic/gen.c (genNot, genNotFloat),

7626 during interrupts. Ensure WSAVE is located at a shared bank address.
7627 2. Fixed page selection in some places
7628 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7629 the registers name strings.
7630 4. Fixed "signed / unsigned compare" compiler warnings.
7631 5. The PIC port manages its own allocation of the general purpose
7632 registers, but makes no attempt to reuse them. As a result when
7633 compiling it soon runs out of general purpose registers. Some
7634 additional code was added to the files pcode.c and device.c to walk
7635 through the function call tree and rename the registers so that they
7645 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7652 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7654 Made bitfield a distinct type from bit so that bitfields
7655 convert as per ANSI C and bits retain their traditional
7656 boolean style behaviour. Implemented bitfield support in
7664 * src/ds390/gen.c: bit v bitfield split
7665 * src/z80/gen.c: New support for bitfields
7666 * support/regression/tests/bitfields.c: reenabled z80,
7669 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7671 Rules 246.x, 247.x relate to bitfields, the others speed up
7672 access to xdata mapped I/O devices.
7674 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7676 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7678 Cleaned up genPackBits and genUnpackBits and added two helper
7679 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7680 for literal assignments in genPackBits (thanks to Frieder for
7686 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7688 Fixed bug #748310 (pointer to function type mishandled when the
7689 function name is omitted). Also fixed a SIGSEGV when a function
7690 attribute (reentrant, etc) is used on a non-function or on a
7691 function but misplaced before the parameter list.

7718 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7720 Made the constant following the "interrupt" keyword optional. If
7721 omitted, the function will not automatically be given an entry
7722 in the interrupt vector table (similar to #pragma NOIV, but
7723 less syntacticly kludgy). The interrupt number is also now
7724 range checked. Also fixed a bug in the high order bit example

7745 unsigned, but are signed by default
7746 * src/SDCCval.c (constVal): rearranged
7747 * src/SDCCval.c (valMod): preliminary fix
7748 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8220 Applied patch from bug 737905 (renamed yylineo to mylineno):
8227 * src/pic16/pcode.c: Cleaned warnings
8228 * src/pic16/pcodeflow.c: Cleaned warnings
8229 * src/pic16/pcoderegs.c: Cleaned warnings
8231 2003-05-19 Scott Dattalo <scott AT dattalo.com>

8245 it can be defined with CFLAGS when running configure
8246 * src/SDCCmain.c: fixed compiling + linking with object files
8248 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8250 * configure.in: configure for pic16 port,
8251 added --disable-pic16-port
8252 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8253 * src/SDCCmain.c: linkOptions is changed to set *,
8254 added if/endif conditional macros to remove options help
8255 messages from optionsTable when a port is not configured, added
8256 support for the PIc16 port in the ports table, when executing
8257 the compiler with no port specified on command line, a default
8258 port is selected with the new macro DEFAULT_PORT which is
8259 defined in port.h, in setDefaultOptions() linkOptions is removed
8260 from initialization assignment, since now it is a set,
8261 parseCmdLine uses setParseWithComma for linkOptions, in
8262 linkEdit() linkOptions are accessed with new function indexSet()
8263 which returns the i'th item of a set variable. See SDCCset.c, in
8264 linkEdit() when calling buildCmdLine(), added linkOptions as
8265 last argument. Now users can pass arguments to gplink via the
8266 -Wl option, main() uses pic16glue() to glue up pic16 programs

8278 * src/pic16/glue.c: commented out some error producing lines
8279 * src/pic16/main.c: __config directives are commented out to stop
8280 gpasm complaining and test the linkage with gplink, _linkCmd and
8281 _asmCmd changed to be more gplink and gpasm friendly
8282 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8283 produced an error when parsed, peep rule 12 is added to utilize
8284 movff, but it is commented out since the pCode does not support
8285 yet a command with 2 address arguments
8287 2003-05-18 <johan AT balder>
8289 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8316 2003-05-11 Borut Razem <borut.razem AT siol.net>
8318 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9307 2003-01-07 <johan AT balder>
9309 * src/SDCCast.c (decorateType): fixed bug #600035

9324 * src/SDCCicode.c: fixed array add
9326 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9327 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9328 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9330 2003-01-04 <johan AT balder>
9332 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9334 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9335 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9337 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9338 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9344 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9345 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9347 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9348 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9350 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9352 * in \sdcc\as\mcs51\ changed these files in order to create an
9353 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9354 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9355 following files to include the previous two files: aslink.dsp,
9356 Makefile.aslink, Makefile.bcc, and Makefile.in.
9358 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9359 .adb instead of .cdb
9361 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9363 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9364 value from option --iram-size.
9366 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9368 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9371 2002-09-18 <wiml AT hhhh.org>
9373 * SDCClrange.h: exposed setFromRange() and setToRange()
9374 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9375 packRegsForAccUse() (bug 542397)
9376 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9377 multiple times and emitting the fetch operations more than once
9378 added aopGetUsesAcc() function to allow binary operators to
9379 fetch their operands in the correct order; made genMinus() emit
9380 compact code for X = LITERAL - Y
9382 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9383 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9384 sprintf() in line 1267.
9386 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9387 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9390 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9391 Changes to aslink (All the changes are marked with 'JCF'):
9393 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9396 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9397 area BSEG. Also moves, if possible, the DATA area down into the internal
9398 ram so more space is available.
9400 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9403 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9404 not bytes. Function summary() which creates a memory usage summary
9405 file with extension .mem. Reports of overlaping stack and small stack
9406 size. If the space for the stack is less than 16 bytes aslink trows a
9409 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9410 the 8051. Option 'y' for memory summary output file.
9412 Changes to sdcc (All the changes are marked with 'JCF'):
9414 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9416 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9417 overlaying area for it (uses RegBankUsed[4]).
9419 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9420 bank zero as used by default. By default aslink locates the stack
9421 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9422 the creation of the .mem file. Delegates the allocation of data area
9423 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9424 the begining of the stack area to aslink.
9426 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9427 glue() in SDCCglue.c creates an area for it.
9429 2002-09-03 Borut Razem <borut.razem AT siol.net>
9430 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9431 sdcc/src/pic/glue.c:
9432 introduced atexit() handler for teporay files removal in case of
9433 errors, assertions, ...
9435 2002-08-29 Borut Razem <borut.razem AT siol.net>
9436 * sdcc/support/cpp2/auto-host_vc_in.h:
9437 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9438 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9439 Maybe there is a similar problem with BORLANDC? It should be checked!
9441 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9442 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9443 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9444 was not executed, and the compiler (cl) launched a warning:
9445 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9447 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9448 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9450 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9451 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9453 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9454 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9455 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9456 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9457 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9458 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9459 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9460 - added Release configuration in VS projects
9461 - review of compiler an linker options
9462 - VC .exe files are generated in bin_vc directory, not to interfere
9463 with binaries generated from other projects (cygwin, mingw, bcc ...)
9465 * sdcc/src/yacc.dsp: added
9467 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9468 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9469 and insert the version number definitions from .version
9471 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9473 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9474 added - genarate auto-host.h using auto-host_vc_in.h as template
9477 removed from CVS, generated automatically
9479 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9480 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9482 2002-08-11 Borut Razem <borut.razem AT siol.net>
9483 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9485 2002-08-10 Borut Razem <borut.razem AT siol.net>
9486 * src/SDCCmain.c (main):
9487 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9488 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9489 The consequence was that some temporary files were not removed.
9492 unification of code in functions tempfilename() and tempfile():
9493 function tempnam() is defined in Visual Studio 6.0 and .NET
9495 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9497 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9498 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9499 - removed compiler command line option /WX: Treats all warnings as errors
9500 - update a list of source files, included into the project
9502 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9503 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9504 changed project type to Generic Project so that can be correcly converted to VS.NET project
9506 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9508 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9510 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9512 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9513 added return 0 statements after assert() to make compiler happy
9515 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9516 added newline in the def file to keep MSC compiler satisfied
9518 * sdcc/src/z80/gen.c:
9519 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
