2153 * src/z80/main.c (_keywords[]),
2154 * src/SDCCglobal.h (struct options),
2156 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2157 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2158 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2159 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2160 always available in leading double underscore form. The C99 support is
2161 mostly missing, but it's a start.
2162 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2163 reserved identifier "__data".
2165 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2167 * src/mcs51/peeph.def: fixed bug 1170013
2169 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

2173 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2175 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
2178 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2180 * src/port.h (struct PORT),
2181 * src/avr/ralloc.c (avr_assignRegisters),
2183 * src/ds390/ralloc.c (ds390_assignRegisters),
2185 * src/hc08/ralloc.c (hc08_assignRegisters),

2206 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
2207 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2208 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2209 immedDom() returning wrong block; probably fixes bug #1160833)
2211 2005-03-20 Borut Razem <borut.razem AT siol.net>
2213 * support/scripts/inc2h.pl: WIN32 port
2215 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2217 * device/lib/makefile.in: added abs.c and labs.c
2219 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2221 * device/include/stdint.h: added
2222 * device/lib/abs.c: added
2223 * device/lib/labs.c: added
2224 * device/include/stdlib.h: added abs() and labs() prototypes

2239 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2241 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2243 * device/lib/printf_large.c: removed inline assembly for portability and
2244 readability. Use printf_fast if speed or size are more important.
2245 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2246 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2248 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2250 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2251 prevent compiler warning
2253 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2255 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2256 moved to level 0 and declared as static. Also they are explicit
2257 placed in access bank. This was necessery because some times they
2258 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2259 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2260 optimizations. Currently only compare to unsigned char is implemented,
2261 * src/pic16/gen.c: added fReturnIdx array,
2262 * (struct resolvedIfx) is moved to gen.h and made public,
2263 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2264 * (aopForSym): added an optimization to directly store in stack of
2265 the operand of a SEND iCode,
2266 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2267 but as registers instead (AOP_REG) using the fReturnIdx array,
2268 * (pic16_freeAsmop): remove the freed register from the
2269 _G.sregsAlloc field,
2270 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2271 a compare of 'WREG',
2272 * (pic16_popGetTempRegCond): changed function prototype, now
2273 function takes also a bitVector argument v which holds the current
2274 set of registers that are allocated for stack access by aopForSym,
2275 registers allocated in aopForSym for accessing stack symbols are not
2276 any more part of the functions usedRegs field,
2277 * (genCall): some times aopOp is called for a stack variable to be
2278 send, aopForSym might perform the push, if this is true make sure
2279 that genCall doesn't push the variable twice by testing _G.resDirect,
2280 * (genFunction): changed testing for unspecified interrupt number
2281 from 256 to INTNO_UNSPEC,
2282 * modified selection scheme of frame pointer generation. Previously
2283 if function did use local registers a frame pointer was generated,
2284 now a frame pointer is generated only if function has arguments
2285 (that need PLUSW2 register access), or has stack arguments, or the
2286 compiler is not instructed to omit the frame pointer,
2287 * (genEndFunction): before restoring local registers that were saved
2288 in the function preamble, also restore the registers that *might*
2289 have been allocated for stack access,
2290 * (genRet): removed some old comments,
2291 * (genCmp, the active (RN's) version): added a call to the
2292 pic16_genCmp_special function to perform the compare with a more
2293 robust and optimized way,
2294 * (genInline): a feature has been added in inline code generation,
2295 which allows a wildcard variable substitution when writing inline
2296 assembly. Code is incomplete and experimental therefore undocumented,
2297 * (genCast): changed order of aopOp for result and right to allow
2298 aopForSym to directly load the result if possible,
2299 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2300 perform an optimized compare on some selected special occasions,
2301 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2302 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2303 generate an IVT any more,
2304 * src/pic16/main.c (pic16_optionsTable): added command line option
2306 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2307 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2309 * src/pic16/NOTES: Raphael Neider added in list of active developers
2310 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2311 jumptable_end to prevent bug #,
2312 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2313 inCond and outCond fields,
2314 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2315 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2316 turn off register spilling,
2317 * (packRegsForOneUse): synced with other ports' versions although it
2318 is not used currently,
2319 * (pic16_packRegisters): added an optimization while reading
2320 structure bitfields, some registers may be saved (malloc code is
2321 decreased by 80 bytes)
2323 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2325 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2326 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2327 this can be optimized more?
2329 2005-03-10 Raphael Neider <rneider AT web.de>
2331 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2332 genNearPointerGet): (hopefully) fixed access to bitfields via
2333 pointers (p->bitN = x; and x = p->bitN; failed)
2335 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2523 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2524 this might fix SIGSEGVs on MinGW...
2525 * src/SDCCopt.c (killDeadCode): restored original behaviour
2526 (volatile operands might get thrown away though)
2528 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2660 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2661 accessing SFRs. Updated all occurences of modification of stack or
2662 frame pointer in gen.c and pcode.c,

2967 Adding support for replacing ljmps with sjmps in jumptables
2968 generated for switch statements. For now you need to set the
2969 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2970 Now 4 algorithms for mcs51 jumptable generation are used:
2971 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2972 addresses loaded pc-relative for up to 112 cases and stack-pushing
2973 target addresses loaded with offset from dptr for up to 256 cases.

2999 Large cummulative patch for pic16 port.
3000 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3001 to call when a stack overflow occurs,
3002 * (malloc.h): added CVS Id tag,
3003 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3005 * added libc directory. The current version of LibC contains string
3006 functions, ctype functions and macros and some functions of the
3007 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3008 be extensively tested in the future. Standard disclaimer here.
3009 Library is not automatically build yet. But one can build it by
3010 invoking 'make' inside the libc directory.
3011 * added ADC library under libio. Preliminary version yet.
3013 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3014 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3015 aopForRemat() now and not by pic16_aopOp(),
3016 * (pic16_popGetTempReg): removed warning messgae when allocating
3017 temporary registers, its a buggy feature and will be removed,
3018 * (pic16_popGet): set register instance field in AOP_CRY,
3019 * (pic16_outBitC): fixed for results in size greater than 1,
3020 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3021 * (pic16_storeForReturn): optimized return of 0,
3022 * (genCmp): experimental code for new genCmp which uses PIC18's
3023 special compare&skip instructions. Initial tests fail some times
3024 with variables grater than 1 byte in size, so new code is disabled,
3025 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3027 * (genCast): began a fix to optimize the casting of a bit to another

6051 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6053 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6054 loaded with the linker search paths (-L arguments) and the libraries
6055 to be linked with the current source (-l arguments). Changes
6056 currently will affect only the pic16 port.
6057 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6058 include path the port specific paths and port specific libraries,
6059 * gplink command now contains the $3 argument,
6060 * src/pic16/device.h,
6061 * src/pic16/device.c,: structure PIC_device is made public and
6062 renamed to PIC16_device, the same for variable Pics which is renamed

6077 Documenting changes from previous commits.
6078 * configure.in (version 1.56),
6079 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6080 when generating output files to configure the pic16 library,
6081 but now I've commented it out, since gputils aren't installed in the
6082 SF compile farm, so library won't compile
6084 * device/lib/Makefile.in (version 1.56): initially I've added in
6085 target 'all' the prerequestive 'model-pic16' so it compiled the
6086 pic16 library, but now I've commented it out for the same reasons
6088 * added targets 'model-pic16' and 'objects-pic16' to compile the
6090 * added target 'port-specific-objects-pic16' to handle the
6091 generated libraries and copy them into the build/ directory
6092 * added target 'clean-intermediate-pic16' to clean intermediate
6093 files into pic16 directory
6094 * in target 'installdirs' added line to create directory pic16 in
6095 the installation path
6097 * device/include/Makefile.in (version 1.11): in target 'install'
6098 added lines to copy all header files to installation path,
6099 * in target 'installdirs' added line create directory for pic16
6100 headers in the installation path

6115 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6116 option so that it actually works. Made it specific to the z80, since
6117 the gbz80 doesn't have these kinds of I/O ports.
6119 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6121 * device/include/z180.h,

6145 via literal number. The symbol is placed in the corresponding
6146 position of the data ram
6147 * (pic16_dump_section): relocatable and absolute uninitialized
6148 data are now emitted in sorted order to reduce section naming,
6149 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6150 weren't marked as being in the access bank,
6152 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6154 Added portion of GNU PIC Library under the directory
6155 device/include/pic16 and device/lib/pic16. These files
6156 contain the declarations of SFRs for the PIC18Fxx2 devices.
6157 The directory is initialized via configure from toplevel.
6159 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6186 * doc/sdccman.lyx: Moved and added some sections, small changes
6187 all over. Telling LaTeX to be less strict with word spacing
6188 to better keep the right margin. Changed some notes about
6189 maintainance of the ports in section 3.2.1 - is it OK like this?
6191 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6228 UPPER for immediate operands,
6229 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6231 * src/pic16/peeph.def: all peepholes with movff are commented out,
6232 because there is a problem in the pcode peep optimizer,
6233 * src/pic16/ralloc.c: the register allocator can now reuse local

6270 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6273 * src/z80/main.c: added missed needLinkerScript flags (more than
6274 one port structure defined in these file)
6275 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6291 needLinkerScript flag
6293 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6294 * src/pic/glue.c: added variable udata_section_name to

6297 * (pic14emitOverlay): modified to emit a commented overlay segment
6298 directive when no overlay data exist
6299 * (picglue): modified to emit uninitialized data segment
6300 according to udata_section_name

6305 arguments via -W option
6306 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6307 object file from '.rel' to '.o' in port->linker structure,

6310 2004-01-07 Borut Razem <borut.razem AT siol.net>
6312 * support/scripts/sdcc.nsi: update PATH
6313 * support/scripts/sdcc.ico: craeted

6320 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6322 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6324 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

6326 include information about variables allocated to the overlay
6329 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6331 * as/mcs51/lkmain.c: Help about -Y option

6343 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6345 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6346 (default behaviour).
6348 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6350 A python script to validate compiler diagnostic messages. It can be
6351 used to verify that sdcc complains about bad c source code and
6352 gives a good location of the error.
6353 * support/valdiag/Makefile,
6354 * support/valdiag/valdiag.py,
6355 * support/valdiag/tests/*
6357 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6359 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6370 * src/common.h: added ifndef/define/endif macros
6371 around the header file.
6372 Bug reported from Jesus Calvino-Fraga
6374 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6376 * sdcc.spec: updated
6377 * device/include/Makefile.in: don't install CVS directories
6378 * device/lib/Makefile.in: added removal of CVS directories after install
6379 * doc/Makefile: fixed install, added local_icons
6380 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6381 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6382 * src/ds390/gen.c (genRightShift): fixed bug #870788
6383 * src/SDCCast.c (decorateType): fixed bug #870781
6385 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6387 PIC16 port related changes:
6388 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6389 added variable stackPos,
6391 * gen.c: genCall, assignResultValue: added support for
6392 pushing/retrieving function parameters to/from stack,
6393 genFunction,genEndFunction: setup stack frame for the
6395 genAddrOf: will be changed according to bug 863624
6397 * added files genutils.c and genutils.h which contain gen*
6398 debugged and optimised functions extracted from gen.c
6400 * glue.c: added variable 'externs' which holds extern symbols,
6401 pic16emitRegularMap: is modified to properly handle relocatable
6402 symbols under the new scheme,
6403 pic16createInterruptVect: is modified
6404 pic16printPublics: is modified to emit 'global' assembler directives,
6405 added pic16_printExterns to print extern symbols,
6406 pic16glue: initializes stack/frame pointer in the beginning of
6407 the assembly output. Temporary hack, will be corrected later,
6408 because gplink yet does not support stack and SDCC does not
6409 yet support a type of crt0.o object to create the final binary.
6411 * Removed many lines that contain 8051 legacy code.
6412 * The code is finally placed under a 'code' directive.
6413 * Added port specific options.
6415 * _process_pragma: simplified since now we do not need *special*
6416 include file to define SFR registers. But a separate header
6417 will be needed. This will be developed later.
6418 * _pic16_parseOptions: added, parses port specific options:
6419 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6420 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6421 --preplace-udata-with=
6423 * _pic16_setDefaultOptions: modified to initialize section names,
6424 but hack is temporarly out of order since it needs improvement.
6425 * _pic16_genAssemblerPreamble: configuration words are emitted by
6426 their address instead of their name. This part is incomplete and
6427 supports only the 18Fxx2 devices. Other devices will emit an error
6428 during assembly since they do not contain the same set of config
6430 * _pic16_genIVT: is modified,
6432 * pcode.c: added definitions for some hardware registers that are needed
6434 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6435 All PCI entries are updated. Now LFSR is supported.
6436 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6437 * added pic16_newpCodeOpLit2 to support instructions with
6438 two literal arguments
6439 * pic16_pCode2str: corrected code that emits assembler instructions
6440 with two literal operands and those that have an access bit modifier
6441 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6442 this fixes a bug which caused some labels to be lost, when an
6443 assembler directive was added, i.e. banksel,
6444 * pic16_FixRegisterBanking: improved logic that causes the insertion
6446 * InlineFunction: functions that are called once, are not any more
6447 inlined. This can be a port option in the future,
6449 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6451 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6452 hold the corresponding uninitialized symbols,
6453 * pic16_allocProcessorRegister: registers have explicit marked the
6455 * pic16_allocInternalRegister: registers are explicit marked as
6457 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6458 processing list, so bit registers were lost,
6461 * ralloc.h: added field 'accessBank' and original symbol operand
6462 in register definition,
6463 * removed the field isMapped from register definition,
6465 ** Several functions have been removed from various sources:
6466 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6467 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6468 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6469 pic16_assignRelocatableRegisters
6471 ** others have been introduced:
6472 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6473 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6475 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6477 * support/scripts/inc2h.pl: changed definition of BIT_AT
6478 to emit 'sbit at' instead of 'bit at'. This was a request.
6480 PIC16 port related preliminary changes:
6481 * gen.c: prefixed function popRegFromString with
6482 pic16_ and all references to it corrected
6483 * pcode.c: all pic16_pc_* hardware registers prefixed
6484 with underscore (_),
6485 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6486 * ralloc.c: newReg(): when register is REG_SFR then
6487 set address to rIdx,
6488 pic16_allocProcessorRegister(): marks register wasUsed=0
6489 pic16_writeUsedRegs(): added a call to assign processor
6490 registers via pic16_assignFixedRegisters
6492 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6494 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6495 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6496 variables in unused register banks. Also the SSEG is placed
6497 wherever there is enough space for it, and IDATA can be anywhere
6498 in internal RAM. For now compile using -Wl-Y[stack_size].
6499 The mem file is different for this option as well, since it
6500 makes no sense of talking about DSEG lenght.
6502 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6504 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6505 in certain cases, e.g. when ROM assignment, patch provided
6506 from Albert den Haan.
6508 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6652 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6653 (allows non-interrupt and interrupt code to safely compete for a resource
6654 without the non-interrupt code having to disable interrupts)
6656 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6658 * src/SDCCicode.c (geniCodeAdd),

6678 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6680 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

6751 it breaks with bitfields, extern declarations, and gcse analysis.
6752 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6753 could be assigned through a pointer, so don't complain.

7531 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7532 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7551 A few small changes that speed up the peephole optimizer.
7555 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7557 Try to make the peephole optimizer smarter by maintaining
7558 an association between the assembly source code and the
7559 iCodes that originated them. Put this information to use
7560 with a new peephole rule condition "notVolatile" so that
7561 the rules can be aggressive yet still safe.
7566 * src/mcs51/peeph.def
7568 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7572 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7573 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7574 if the left or right operand symbols have the accuse flag set.
7576 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7578 Changed the type of the result of the ! (NOT) operator to char;
7579 previously it returned the same type as the source. This allows
7580 us to eliminate all the genFloatNot functions (all of its target
7581 implementations were very buggy) since !float can use the same
7584 * src/SDCCicode.c (ast2iCode): ! returns char

7593 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7594 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7595 during interrupts. Ensure WSAVE is located at a shared bank address.
7596 2. Fixed page selection in some places
7597 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7598 the registers name strings.
7599 4. Fixed "signed / unsigned compare" compiler warnings.
7600 5. The PIC port manages its own allocation of the general purpose
7601 registers, but makes no attempt to reuse them. As a result when
7602 compiling it soon runs out of general purpose registers. Some
7603 additional code was added to the files pcode.c and device.c to walk
7604 through the function call tree and rename the registers so that they
7614 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7621 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7623 Made bitfield a distinct type from bit so that bitfields
7624 convert as per ANSI C and bits retain their traditional
7625 boolean style behaviour. Implemented bitfield support in
7633 * src/ds390/gen.c: bit v bitfield split
7634 * src/z80/gen.c: New support for bitfields
7635 * support/regression/tests/bitfields.c: reenabled z80,
7638 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7689 Made the constant following the "interrupt" keyword optional. If
7690 omitted, the function will not automatically be given an entry
7691 in the interrupt vector table (similar to #pragma NOIV, but
7692 less syntacticly kludgy). The interrupt number is also now
7693 range checked. Also fixed a bug in the high order bit example

8215 * src/SDCCmain.c: fixed compiling + linking with object files
8217 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8219 * configure.in: configure for pic16 port,
8220 added --disable-pic16-port
8221 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8222 * src/SDCCmain.c: linkOptions is changed to set *,
8223 added if/endif conditional macros to remove options help
8224 messages from optionsTable when a port is not configured, added
8225 support for the PIc16 port in the ports table, when executing
8226 the compiler with no port specified on command line, a default
8227 port is selected with the new macro DEFAULT_PORT which is
8228 defined in port.h, in setDefaultOptions() linkOptions is removed
8229 from initialization assignment, since now it is a set,
8230 parseCmdLine uses setParseWithComma for linkOptions, in
8231 linkEdit() linkOptions are accessed with new function indexSet()
8232 which returns the i'th item of a set variable. See SDCCset.c, in
8233 linkEdit() when calling buildCmdLine(), added linkOptions as
8234 last argument. Now users can pass arguments to gplink via the
8235 -Wl option, main() uses pic16glue() to glue up pic16 programs
8236 * src/SDCCpeeph.c: various changes to support pic16
8237 * src/SDCCset.c: added function void *indexSet(set *, int) to

8245 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8247 * src/pic16/glue.c: commented out some error producing lines
8248 * src/pic16/main.c: __config directives are commented out to stop
8249 gpasm complaining and test the linkage with gplink, _linkCmd and
8250 _asmCmd changed to be more gplink and gpasm friendly
8251 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8252 produced an error when parsed, peep rule 12 is added to utilize
8253 movff, but it is commented out since the pCode does not support
8254 yet a command with 2 address arguments
8256 2003-05-18 <johan AT balder>

8285 2003-05-11 Borut Razem <borut.razem AT siol.net>
8287 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9293 * src/SDCCicode.c: fixed array add
9295 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9296 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9297 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9299 2003-01-04 <johan AT balder>
9301 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9303 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9304 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9306 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9307 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9313 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9314 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9316 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9317 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9319 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9321 * in \sdcc\as\mcs51\ changed these files in order to create an
9322 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9323 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9324 following files to include the previous two files: aslink.dsp,
9325 Makefile.aslink, Makefile.bcc, and Makefile.in.
9327 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9328 .adb instead of .cdb
9330 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9332 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9333 value from option --iram-size.
9335 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9337 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9340 2002-09-18 <wiml AT hhhh.org>
9342 * SDCClrange.h: exposed setFromRange() and setToRange()
9343 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9344 packRegsForAccUse() (bug 542397)
9345 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9346 multiple times and emitting the fetch operations more than once
9347 added aopGetUsesAcc() function to allow binary operators to
9348 fetch their operands in the correct order; made genMinus() emit
9349 compact code for X = LITERAL - Y
9351 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9352 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9353 sprintf() in line 1267.
9355 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9356 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9359 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9360 Changes to aslink (All the changes are marked with 'JCF'):
9362 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9365 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9366 area BSEG. Also moves, if possible, the DATA area down into the internal
9367 ram so more space is available.
9369 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9372 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9373 not bytes. Function summary() which creates a memory usage summary
9374 file with extension .mem. Reports of overlaping stack and small stack
9375 size. If the space for the stack is less than 16 bytes aslink trows a
9378 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9379 the 8051. Option 'y' for memory summary output file.
9381 Changes to sdcc (All the changes are marked with 'JCF'):
9383 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9385 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9386 overlaying area for it (uses RegBankUsed[4]).
9388 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9389 bank zero as used by default. By default aslink locates the stack
9390 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9391 the creation of the .mem file. Delegates the allocation of data area
9392 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9393 the begining of the stack area to aslink.
9395 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9396 glue() in SDCCglue.c creates an area for it.
9398 2002-09-03 Borut Razem <borut.razem AT siol.net>
9399 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9400 sdcc/src/pic/glue.c:
9401 introduced atexit() handler for teporay files removal in case of
9402 errors, assertions, ...
9404 2002-08-29 Borut Razem <borut.razem AT siol.net>
9405 * sdcc/support/cpp2/auto-host_vc_in.h:
9406 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9407 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9408 Maybe there is a similar problem with BORLANDC? It should be checked!
9410 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9411 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9412 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9413 was not executed, and the compiler (cl) launched a warning:
9414 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9416 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9417 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9419 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9420 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9422 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9423 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9424 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9425 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9426 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9427 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9428 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9429 - added Release configuration in VS projects
9430 - review of compiler an linker options
9431 - VC .exe files are generated in bin_vc directory, not to interfere
9432 with binaries generated from other projects (cygwin, mingw, bcc ...)
9434 * sdcc/src/yacc.dsp: added
9436 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9437 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9438 and insert the version number definitions from .version
9440 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9442 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9443 added - genarate auto-host.h using auto-host_vc_in.h as template
9446 removed from CVS, generated automatically
9448 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9449 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9451 2002-08-11 Borut Razem <borut.razem AT siol.net>
9452 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9454 2002-08-10 Borut Razem <borut.razem AT siol.net>
9455 * src/SDCCmain.c (main):
9456 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9457 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9458 The consequence was that some temporary files were not removed.
9461 unification of code in functions tempfilename() and tempfile():
9462 function tempnam() is defined in Visual Studio 6.0 and .NET
9464 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9466 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9467 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9468 - removed compiler command line option /WX: Treats all warnings as errors
9469 - update a list of source files, included into the project
9471 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9472 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9473 changed project type to Generic Project so that can be correcly converted to VS.NET project
9475 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9477 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9479 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9481 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9482 added return 0 statements after assert() to make compiler happy
9484 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9485 added newline in the def file to keep MSC compiler satisfied
9487 * sdcc/src/z80/gen.c:
9488 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9489 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9490 - solved MSC error in function aopDump()
9492 * sdcc_vc.h: define PREFIX as "\\sdcc"
9494 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9495 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9497 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9498 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9499 - Rewrote the register banking algorithm.
9500 - Added pCode live-range analysis to registers (for now, only non-used and
9501 singly-used registers optimized away)
9503 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9505 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
9507 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9508 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9510 2002-04-22 Michael Hope <michaelh AT vroom>
9512 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
9514 * configure.in (DD_COPT): Added include support required for gbdk.
9516 * .version: Bumped version number just to increase it.
9518 * src/SDCCmain.c: Added -nostdinc to the default options.
9520 2002-04-15 Michael Hope <michaelh AT vroom>
9522 * device/lib/z80/printf.c (sprintf): Added.
