926 on rIfx (genCmp was broken)
928 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
930 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
931 * src/z80/main.c (_keywords[]),
932 * src/SDCCglobal.h (struct options),
934 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
935 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
936 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
937 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
938 always available in leading double underscore form. The C99 support is
939 mostly missing, but it's a start.
940 * support/regression/tests/bug-227710.c: fixed nonconforming use of
941 reserved identifier "__data".
943 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1019 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1021 * device/lib/printf_large.c: removed inline assembly for portability and
1022 readability. Use printf_fast if speed or size are more important.
1023 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1024 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1026 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1028 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1029 prevent compiler warning
1031 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1033 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1034 moved to level 0 and declared as static. Also they are explicit
1035 placed in access bank. This was necessery because some times they
1036 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1037 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1038 optimizations. Currently only compare to unsigned char is implemented,
1039 * src/pic16/gen.c: added fReturnIdx array,
1040 * (struct resolvedIfx) is moved to gen.h and made public,
1041 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1042 * (aopForSym): added an optimization to directly store in stack of
1043 the operand of a SEND iCode,
1044 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1045 but as registers instead (AOP_REG) using the fReturnIdx array,
1046 * (pic16_freeAsmop): remove the freed register from the
1047 _G.sregsAlloc field,
1048 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1049 a compare of 'WREG',
1050 * (pic16_popGetTempRegCond): changed function prototype, now
1051 function takes also a bitVector argument v which holds the current
1052 set of registers that are allocated for stack access by aopForSym,
1053 registers allocated in aopForSym for accessing stack symbols are not
1054 any more part of the functions usedRegs field,
1055 * (genCall): some times aopOp is called for a stack variable to be
1056 send, aopForSym might perform the push, if this is true make sure
1057 that genCall doesn't push the variable twice by testing _G.resDirect,
1058 * (genFunction): changed testing for unspecified interrupt number
1059 from 256 to INTNO_UNSPEC,
1060 * modified selection scheme of frame pointer generation. Previously
1061 if function did use local registers a frame pointer was generated,
1062 now a frame pointer is generated only if function has arguments
1063 (that need PLUSW2 register access), or has stack arguments, or the
1064 compiler is not instructed to omit the frame pointer,
1065 * (genEndFunction): before restoring local registers that were saved
1066 in the function preamble, also restore the registers that *might*
1067 have been allocated for stack access,
1068 * (genRet): removed some old comments,
1069 * (genCmp, the active (RN's) version): added a call to the
1070 pic16_genCmp_special function to perform the compare with a more
1071 robust and optimized way,
1072 * (genInline): a feature has been added in inline code generation,
1073 which allows a wildcard variable substitution when writing inline
1074 assembly. Code is incomplete and experimental therefore undocumented,
1075 * (genCast): changed order of aopOp for result and right to allow
1076 aopForSym to directly load the result if possible,
1077 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1078 perform an optimized compare on some selected special occasions,
1079 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1080 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1081 generate an IVT any more,
1082 * src/pic16/main.c (pic16_optionsTable): added command line option
1084 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1085 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1087 * src/pic16/NOTES: Raphael Neider added in list of active developers
1088 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1089 jumptable_end to prevent bug #,
1090 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1091 inCond and outCond fields,
1092 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1093 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1094 turn off register spilling,
1095 * (packRegsForOneUse): synced with other ports' versions although it
1096 is not used currently,
1097 * (pic16_packRegisters): added an optimization while reading
1098 structure bitfields, some registers may be saved (malloc code is
1099 decreased by 80 bytes)
1101 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1103 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1104 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1105 this can be optimized more?
1107 2005-03-10 Raphael Neider <rneider AT web.de>
1109 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1110 genNearPointerGet): (hopefully) fixed access to bitfields via
1111 pointers (p->bitN = x; and x = p->bitN; failed)
1113 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1290 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1291 (sizeof(sectNames) changed to sizeof(sectName))

1299 of (byte sized) temporaries (assign them to WREG for now)
1300 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1301 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1302 this might fix SIGSEGVs on MinGW...
1303 * src/SDCCopt.c (killDeadCode): restored original behaviour
1304 (volatile operands might get thrown away though)
1306 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1308 * src/pic16/gen.c: fixed bug #1106975,

1760 * support/regression/tests/bug1057979.c: added test for bug 1073386
1762 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1764 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
1767 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1769 * src/pic16/device.h,
1770 * src/pic16/genarith.c,
1773 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1775 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1777 Large cummulative patch for pic16 port.
1778 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1779 to call when a stack overflow occurs,
1780 * (malloc.h): added CVS Id tag,
1781 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1783 * added libc directory. The current version of LibC contains string
1784 functions, ctype functions and macros and some functions of the
1785 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1786 be extensively tested in the future. Standard disclaimer here.
1787 Library is not automatically build yet. But one can build it by
1788 invoking 'make' inside the libc directory.
1789 * added ADC library under libio. Preliminary version yet.
1791 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1792 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1793 aopForRemat() now and not by pic16_aopOp(),
1794 * (pic16_popGetTempReg): removed warning messgae when allocating
1795 temporary registers, its a buggy feature and will be removed,
1796 * (pic16_popGet): set register instance field in AOP_CRY,
1797 * (pic16_outBitC): fixed for results in size greater than 1,
1798 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1799 * (pic16_storeForReturn): optimized return of 0,
1800 * (genCmp): experimental code for new genCmp which uses PIC18's
1801 special compare&skip instructions. Initial tests fail some times
1802 with variables grater than 1 byte in size, so new code is disabled,
1803 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1805 * (genCast): began a fix to optimize the casting of a bit to another
1806 bit, now assigning a bitfield to another bitfield will fail, sorry,
1807 * src/pic16/main.c: disabled the use of lr-support feature,
1808 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1809 * added some function prototypes, added function _debugf prototype,
1810 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1811 bits with offset (case PO_GPR_BIT),
1812 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1814 * (isBankInstruction): modified to return 0 for no banking instruction,
1815 and 1 for banking instruction,
1816 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1817 caused stop processing pCodes after a inline assembly block,
1818 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1819 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1820 registers when it shouldn't,
1821 * src/pic16/ralloc.c (allocReg): add preliminary support for
1822 supporting a limited set of temporary registers,
1824 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1826 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1827 genDataPointerSet): ensure assignments always copy in MSB to LSB
1829 (loadRegFromAop): recognize CLRH optimization,
1830 (genFunction): optimize RECEIVE iCodes in reentrant functions
1832 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1834 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1835 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1837 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1843 * device/lib/_gptrget.c (_gptrget),
1844 * device/lib/_gptrgetc.c (_gptrgetc),
1845 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1846 instead of sjmp to ret
1847 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1848 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

4829 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4831 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4832 loaded with the linker search paths (-L arguments) and the libraries
4833 to be linked with the current source (-l arguments). Changes
4834 currently will affect only the pic16 port.
4835 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4836 include path the port specific paths and port specific libraries,
4837 * gplink command now contains the $3 argument,
4838 * src/pic16/device.h,
4839 * src/pic16/device.c,: structure PIC_device is made public and
4840 renamed to PIC16_device, the same for variable Pics which is renamed

4855 Documenting changes from previous commits.
4856 * configure.in (version 1.56),
4857 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4858 when generating output files to configure the pic16 library,
4859 but now I've commented it out, since gputils aren't installed in the
4860 SF compile farm, so library won't compile
4862 * device/lib/Makefile.in (version 1.56): initially I've added in
4863 target 'all' the prerequestive 'model-pic16' so it compiled the
4864 pic16 library, but now I've commented it out for the same reasons
4866 * added targets 'model-pic16' and 'objects-pic16' to compile the
4868 * added target 'port-specific-objects-pic16' to handle the
4869 generated libraries and copy them into the build/ directory
4870 * added target 'clean-intermediate-pic16' to clean intermediate
4871 files into pic16 directory
4872 * in target 'installdirs' added line to create directory pic16 in

4893 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4894 option so that it actually works. Made it specific to the z80, since
4895 the gbz80 doesn't have these kinds of I/O ports.
4897 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4899 * device/include/z180.h,

4923 via literal number. The symbol is placed in the corresponding
4924 position of the data ram
4925 * (pic16_dump_section): relocatable and absolute uninitialized
4926 data are now emitted in sorted order to reduce section naming,
4927 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4928 weren't marked as being in the access bank,
4930 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4932 Added portion of GNU PIC Library under the directory
4933 device/include/pic16 and device/lib/pic16. These files
4934 contain the declarations of SFRs for the PIC18Fxx2 devices.
4935 The directory is initialized via configure from toplevel.
4937 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4939 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4964 * doc/sdccman.lyx: Moved and added some sections, small changes
4965 all over. Telling LaTeX to be less strict with word spacing
4966 to better keep the right margin. Changed some notes about
4967 maintainance of the ports in section 3.2.1 - is it OK like this?
4969 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5006 UPPER for immediate operands,
5007 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5009 * src/pic16/peeph.def: all peepholes with movff are commented out,
5010 because there is a problem in the pcode peep optimizer,
5011 * src/pic16/ralloc.c: the register allocator can now reuse local
5012 function symbols for another function. This saves register usage.
5013 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5015 Added file src/pic16/NOTES with information about program writing on
5016 the current port version.

5045 gen51Code): more efficient parameter receive for --model-large
5048 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5051 * src/z80/main.c: added missed needLinkerScript flags (more than
5052 one port structure defined in these file)
5053 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5069 needLinkerScript flag
5071 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5072 * src/pic/glue.c: added variable udata_section_name to
5073 override default uninitialized data segment definition for
5074 devices only with SHAREBANK memory (reported from Erik Epetrich)
5075 * (pic14emitOverlay): modified to emit a commented overlay segment
5076 directive when no overlay data exist
5077 * (picglue): modified to emit uninitialized data segment
5078 according to udata_section_name

5088 2004-01-07 Borut Razem <borut.razem AT siol.net>
5090 * support/scripts/sdcc.nsi: update PATH
5091 * support/scripts/sdcc.ico: craeted

5096 * doc/Makefile: fix install
5098 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5100 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5102 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
5103 how the function variable allocation summary is displayed; also
5104 include information about variables allocated to the overlay
5107 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5109 * as/mcs51/lkmain.c: Help about -Y option

5119 LEFT_OP (left shift)
5121 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5123 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5124 (default behaviour).
5126 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5128 A python script to validate compiler diagnostic messages. It can be
5129 used to verify that sdcc complains about bad c source code and
5130 gives a good location of the error.
5131 * support/valdiag/Makefile,
5132 * support/valdiag/valdiag.py,
5133 * support/valdiag/tests/*
5135 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5137 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5148 * src/common.h: added ifndef/define/endif macros
5149 around the header file.
5150 Bug reported from Jesus Calvino-Fraga
5152 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5154 * sdcc.spec: updated
5155 * device/include/Makefile.in: don't install CVS directories
5156 * device/lib/Makefile.in: added removal of CVS directories after install
5157 * doc/Makefile: fixed install, added local_icons
5158 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5159 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5160 * src/ds390/gen.c (genRightShift): fixed bug #870788
5161 * src/SDCCast.c (decorateType): fixed bug #870781
5163 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5165 PIC16 port related changes:
5166 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5167 added variable stackPos,
5169 * gen.c: genCall, assignResultValue: added support for
5170 pushing/retrieving function parameters to/from stack,
5171 genFunction,genEndFunction: setup stack frame for the
5173 genAddrOf: will be changed according to bug 863624
5175 * added files genutils.c and genutils.h which contain gen*
5176 debugged and optimised functions extracted from gen.c
5178 * glue.c: added variable 'externs' which holds extern symbols,
5179 pic16emitRegularMap: is modified to properly handle relocatable
5180 symbols under the new scheme,
5181 pic16createInterruptVect: is modified
5182 pic16printPublics: is modified to emit 'global' assembler directives,
5183 added pic16_printExterns to print extern symbols,
5184 pic16glue: initializes stack/frame pointer in the beginning of
5185 the assembly output. Temporary hack, will be corrected later,
5186 because gplink yet does not support stack and SDCC does not
5187 yet support a type of crt0.o object to create the final binary.
5189 * Removed many lines that contain 8051 legacy code.
5190 * The code is finally placed under a 'code' directive.
5191 * Added port specific options.
5193 * _process_pragma: simplified since now we do not need *special*
5194 include file to define SFR registers. But a separate header
5195 will be needed. This will be developed later.
5196 * _pic16_parseOptions: added, parses port specific options:
5197 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5198 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5199 --preplace-udata-with=
5201 * _pic16_setDefaultOptions: modified to initialize section names,
5202 but hack is temporarly out of order since it needs improvement.
5203 * _pic16_genAssemblerPreamble: configuration words are emitted by
5204 their address instead of their name. This part is incomplete and
5205 supports only the 18Fxx2 devices. Other devices will emit an error
5206 during assembly since they do not contain the same set of config
5208 * _pic16_genIVT: is modified,
5210 * pcode.c: added definitions for some hardware registers that are needed
5212 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5213 All PCI entries are updated. Now LFSR is supported.
5214 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5215 * added pic16_newpCodeOpLit2 to support instructions with
5216 two literal arguments
5217 * pic16_pCode2str: corrected code that emits assembler instructions
5218 with two literal operands and those that have an access bit modifier
5219 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5220 this fixes a bug which caused some labels to be lost, when an
5221 assembler directive was added, i.e. banksel,
5222 * pic16_FixRegisterBanking: improved logic that causes the insertion
5224 * InlineFunction: functions that are called once, are not any more
5225 inlined. This can be a port option in the future,
5227 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5229 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5230 hold the corresponding uninitialized symbols,
5231 * pic16_allocProcessorRegister: registers have explicit marked the
5233 * pic16_allocInternalRegister: registers are explicit marked as
5235 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5236 processing list, so bit registers were lost,
5239 * ralloc.h: added field 'accessBank' and original symbol operand
5240 in register definition,
5241 * removed the field isMapped from register definition,
5243 ** Several functions have been removed from various sources:
5244 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5245 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5246 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5247 pic16_assignRelocatableRegisters
5249 ** others have been introduced:
5250 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5251 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5253 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5255 * support/scripts/inc2h.pl: changed definition of BIT_AT
5256 to emit 'sbit at' instead of 'bit at'. This was a request.
5258 PIC16 port related preliminary changes:
5259 * gen.c: prefixed function popRegFromString with
5260 pic16_ and all references to it corrected
5261 * pcode.c: all pic16_pc_* hardware registers prefixed
5262 with underscore (_),
5263 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5264 * ralloc.c: newReg(): when register is REG_SFR then
5265 set address to rIdx,
5266 pic16_allocProcessorRegister(): marks register wasUsed=0
5267 pic16_writeUsedRegs(): added a call to assign processor
5268 registers via pic16_assignFixedRegisters
5270 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5272 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5273 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5274 variables in unused register banks. Also the SSEG is placed
5275 wherever there is enough space for it, and IDATA can be anywhere
5276 in internal RAM. For now compile using -Wl-Y[stack_size].
5277 The mem file is different for this option as well, since it
5278 makes no sense of talking about DSEG lenght.
5280 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5282 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5283 in certain cases, e.g. when ROM assignment, patch provided
5284 from Albert den Haan.
5286 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5831 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5833 Fixed a number of problems revealed by bug #827883.
5834 * src/SDCCloop.c (loopInvariants): Spill location of the
5835 result operand should be recomputed if extracted from
5836 a loop. Also, don't extract assignments of an iTemp
5838 * src/SDCCast.c (isConformingBody): loop reversal should
5839 not occur if the control variable is involved with a
5840 relational operator.

6329 A few small changes that speed up the peephole optimizer.
6333 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6335 Try to make the peephole optimizer smarter by maintaining
6336 an association between the assembly source code and the
6337 iCodes that originated them. Put this information to use
6338 with a new peephole rule condition "notVolatile" so that
6339 the rules can be aggressive yet still safe.
6344 * src/mcs51/peeph.def
6346 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6356 Changed the type of the result of the ! (NOT) operator to char;
6357 previously it returned the same type as the source. This allows
6358 us to eliminate all the genFloatNot functions (all of its target
6359 implementations were very buggy) since !float can use the same

6371 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6372 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6373 during interrupts. Ensure WSAVE is located at a shared bank address.
6374 2. Fixed page selection in some places
6375 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6376 the registers name strings.
6377 4. Fixed "signed / unsigned compare" compiler warnings.
6378 5. The PIC port manages its own allocation of the general purpose
6379 registers, but makes no attempt to reuse them. As a result when
6380 compiling it soon runs out of general purpose registers. Some
6381 additional code was added to the files pcode.c and device.c to walk
6382 through the function call tree and rename the registers so that they
6392 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6399 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6401 Made bitfield a distinct type from bit so that bitfields
6402 convert as per ANSI C and bits retain their traditional
6403 boolean style behaviour. Implemented bitfield support in
6411 * src/ds390/gen.c: bit v bitfield split
6412 * src/z80/gen.c: New support for bitfields
6413 * support/regression/tests/bitfields.c: reenabled z80,
6416 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6418 Rules 246.x, 247.x relate to bitfields, the others speed up
6419 access to xdata mapped I/O devices.
6421 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6423 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6425 Cleaned up genPackBits and genUnpackBits and added two helper
6426 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6427 for literal assignments in genPackBits (thanks to Frieder for
6433 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6435 Fixed bug #748310 (pointer to function type mishandled when the
6436 function name is omitted). Also fixed a SIGSEGV when a function
6437 attribute (reentrant, etc) is used on a non-function or on a
6438 function but misplaced before the parameter list.

6465 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6467 Made the constant following the "interrupt" keyword optional. If
6468 omitted, the function will not automatically be given an entry
6469 in the interrupt vector table (similar to #pragma NOIV, but
6470 less syntacticly kludgy). The interrupt number is also now
6471 range checked. Also fixed a bug in the high order bit example

6949 * doc/sdccman.lyx: added latex preamble for hyperref package.
6950 Using pdflatex this will give you a hyperlinked pdf file with

6998 added --disable-pic16-port
6999 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7000 * src/SDCCmain.c: linkOptions is changed to set *,
7001 added if/endif conditional macros to remove options help
7002 messages from optionsTable when a port is not configured, added
7003 support for the PIc16 port in the ports table, when executing
7004 the compiler with no port specified on command line, a default
7005 port is selected with the new macro DEFAULT_PORT which is
7006 defined in port.h, in setDefaultOptions() linkOptions is removed
7007 from initialization assignment, since now it is a set,
7008 parseCmdLine uses setParseWithComma for linkOptions, in
7009 linkEdit() linkOptions are accessed with new function indexSet()
7010 which returns the i'th item of a set variable. See SDCCset.c, in
7011 linkEdit() when calling buildCmdLine(), added linkOptions as
7012 last argument. Now users can pass arguments to gplink via the
7013 -Wl option, main() uses pic16glue() to glue up pic16 programs

7025 * src/pic16/glue.c: commented out some error producing lines
7026 * src/pic16/main.c: __config directives are commented out to stop
7027 gpasm complaining and test the linkage with gplink, _linkCmd and
7028 _asmCmd changed to be more gplink and gpasm friendly
7029 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7030 produced an error when parsed, peep rule 12 is added to utilize
7031 movff, but it is commented out since the pCode does not support
7032 yet a command with 2 address arguments
7034 2003-05-18 <johan AT balder>
7036 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7061 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7063 2003-05-11 Borut Razem <borut.razem AT siol.net>
7065 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7066 the path of bin directory, so that PATH is the only env. variable, which has to be set
7067 in case of standard installation.

8071 * src/SDCCicode.c: fixed array add
8073 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8074 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8075 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8077 2003-01-04 <johan AT balder>
8079 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8081 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8082 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8094 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8095 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8097 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8099 * in \sdcc\as\mcs51\ changed these files in order to create an
8100 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8101 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8102 following files to include the previous two files: aslink.dsp,
8103 Makefile.aslink, Makefile.bcc, and Makefile.in.
8105 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8106 .adb instead of .cdb
8108 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8110 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8111 value from option --iram-size.
8113 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8115 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8118 2002-09-18 <wiml AT hhhh.org>
8120 * SDCClrange.h: exposed setFromRange() and setToRange()
8121 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8122 packRegsForAccUse() (bug 542397)
8123 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8124 multiple times and emitting the fetch operations more than once
8125 added aopGetUsesAcc() function to allow binary operators to
8126 fetch their operands in the correct order; made genMinus() emit
8127 compact code for X = LITERAL - Y
8129 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8130 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8131 sprintf() in line 1267.
8133 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8134 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8137 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8138 Changes to aslink (All the changes are marked with 'JCF'):
8140 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8143 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8144 area BSEG. Also moves, if possible, the DATA area down into the internal
8145 ram so more space is available.
8147 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8150 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8151 not bytes. Function summary() which creates a memory usage summary
8152 file with extension .mem. Reports of overlaping stack and small stack
8153 size. If the space for the stack is less than 16 bytes aslink trows a
8156 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8157 the 8051. Option 'y' for memory summary output file.
8159 Changes to sdcc (All the changes are marked with 'JCF'):
8161 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8163 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8164 overlaying area for it (uses RegBankUsed[4]).
8166 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8167 bank zero as used by default. By default aslink locates the stack
8168 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8169 the creation of the .mem file. Delegates the allocation of data area
8170 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8171 the begining of the stack area to aslink.
8173 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8174 glue() in SDCCglue.c creates an area for it.
8176 2002-09-03 Borut Razem <borut.razem AT siol.net>
8177 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8178 sdcc/src/pic/glue.c:
8179 introduced atexit() handler for teporay files removal in case of
8180 errors, assertions, ...
8182 2002-08-29 Borut Razem <borut.razem AT siol.net>
8183 * sdcc/support/cpp2/auto-host_vc_in.h:
8184 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8185 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8186 Maybe there is a similar problem with BORLANDC? It should be checked!
8188 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8189 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8190 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8191 was not executed, and the compiler (cl) launched a warning:
8192 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8194 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8195 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8197 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8198 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8200 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8201 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

8203 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8204 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8205 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8206 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8207 - added Release configuration in VS projects
8208 - review of compiler an linker options
8209 - VC .exe files are generated in bin_vc directory, not to interfere
8210 with binaries generated from other projects (cygwin, mingw, bcc ...)
8212 * sdcc/src/yacc.dsp: added
8214 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8215 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8216 and insert the version number definitions from .version
8218 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8220 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8221 added - genarate auto-host.h using auto-host_vc_in.h as template
8224 removed from CVS, generated automatically
8226 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8227 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8229 2002-08-11 Borut Razem <borut.razem AT siol.net>
8230 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8232 2002-08-10 Borut Razem <borut.razem AT siol.net>
8233 * src/SDCCmain.c (main):
8234 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8235 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8236 The consequence was that some temporary files were not removed.
8239 unification of code in functions tempfilename() and tempfile():
8240 function tempnam() is defined in Visual Studio 6.0 and .NET
8242 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8244 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8245 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8246 - removed compiler command line option /WX: Treats all warnings as errors
8247 - update a list of source files, included into the project
8249 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8250 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
