935 on rIfx (genCmp was broken)
937 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
939 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
940 * src/z80/main.c (_keywords[]),
941 * src/SDCCglobal.h (struct options),
943 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
944 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
945 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
946 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
947 always available in leading double underscore form. The C99 support is
948 mostly missing, but it's a start.
949 * support/regression/tests/bug-227710.c: fixed nonconforming use of
950 reserved identifier "__data".
952 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

998 2005-03-20 Borut Razem <borut.razem AT siol.net>
1000 * support/scripts/inc2h.pl: WIN32 port

1006 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1008 * device/include/stdint.h: added
1009 * device/lib/abs.c: added

1026 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1028 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1030 * device/lib/printf_large.c: removed inline assembly for portability and
1031 readability. Use printf_fast if speed or size are more important.
1032 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1033 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1035 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1037 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1038 prevent compiler warning
1040 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1042 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1043 moved to level 0 and declared as static. Also they are explicit
1044 placed in access bank. This was necessery because some times they
1045 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1046 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1047 optimizations. Currently only compare to unsigned char is implemented,
1048 * src/pic16/gen.c: added fReturnIdx array,
1049 * (struct resolvedIfx) is moved to gen.h and made public,
1050 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1051 * (aopForSym): added an optimization to directly store in stack of
1052 the operand of a SEND iCode,
1053 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1054 but as registers instead (AOP_REG) using the fReturnIdx array,
1055 * (pic16_freeAsmop): remove the freed register from the
1056 _G.sregsAlloc field,
1057 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1058 a compare of 'WREG',
1059 * (pic16_popGetTempRegCond): changed function prototype, now
1060 function takes also a bitVector argument v which holds the current
1061 set of registers that are allocated for stack access by aopForSym,
1062 registers allocated in aopForSym for accessing stack symbols are not
1063 any more part of the functions usedRegs field,
1064 * (genCall): some times aopOp is called for a stack variable to be
1065 send, aopForSym might perform the push, if this is true make sure
1066 that genCall doesn't push the variable twice by testing _G.resDirect,
1067 * (genFunction): changed testing for unspecified interrupt number
1068 from 256 to INTNO_UNSPEC,
1069 * modified selection scheme of frame pointer generation. Previously
1070 if function did use local registers a frame pointer was generated,
1071 now a frame pointer is generated only if function has arguments
1072 (that need PLUSW2 register access), or has stack arguments, or the
1073 compiler is not instructed to omit the frame pointer,
1074 * (genEndFunction): before restoring local registers that were saved
1075 in the function preamble, also restore the registers that *might*
1076 have been allocated for stack access,
1077 * (genRet): removed some old comments,
1078 * (genCmp, the active (RN's) version): added a call to the
1079 pic16_genCmp_special function to perform the compare with a more
1080 robust and optimized way,
1081 * (genInline): a feature has been added in inline code generation,
1082 which allows a wildcard variable substitution when writing inline
1083 assembly. Code is incomplete and experimental therefore undocumented,
1084 * (genCast): changed order of aopOp for result and right to allow
1085 aopForSym to directly load the result if possible,
1086 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1087 perform an optimized compare on some selected special occasions,
1088 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1089 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1090 generate an IVT any more,
1091 * src/pic16/main.c (pic16_optionsTable): added command line option
1093 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1094 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1096 * src/pic16/NOTES: Raphael Neider added in list of active developers
1097 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1098 jumptable_end to prevent bug #,
1099 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1100 inCond and outCond fields,
1101 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1102 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1103 turn off register spilling,
1104 * (packRegsForOneUse): synced with other ports' versions although it
1105 is not used currently,
1106 * (pic16_packRegisters): added an optimization while reading
1107 structure bitfields, some registers may be saved (malloc code is
1108 decreased by 80 bytes)
1110 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1112 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1113 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1114 this can be optimized more?
1116 2005-03-10 Raphael Neider <rneider AT web.de>
1118 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1119 genNearPointerGet): (hopefully) fixed access to bitfields via
1120 pointers (p->bitN = x; and x = p->bitN; failed)
1122 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1165 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1166 to keep the correct label reference count when adding/removing references
1167 to labels. A peephole file using this is appended to patch #1144962.

1299 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1300 (sizeof(sectNames) changed to sizeof(sectName))
1301 Both patches fix segfaults under MinGW.

1306 Safe_[mc]?alloc()'ed variables
1307 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1308 of (byte sized) temporaries (assign them to WREG for now)
1309 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1310 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1311 this might fix SIGSEGVs on MinGW...
1312 * src/SDCCopt.c (killDeadCode): restored original behaviour
1313 (volatile operands might get thrown away though)
1315 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1317 * src/pic16/gen.c: fixed bug #1106975,

1758 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1759 addresses loaded pc-relative for up to 112 cases and stack-pushing
1760 target addresses loaded with offset from dptr for up to 256 cases.

1776 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1778 * src/pic16/device.h,
1779 * src/pic16/genarith.c,
1782 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1784 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1786 Large cummulative patch for pic16 port.
1787 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1788 to call when a stack overflow occurs,
1789 * (malloc.h): added CVS Id tag,
1790 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1792 * added libc directory. The current version of LibC contains string
1793 functions, ctype functions and macros and some functions of the
1794 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1795 be extensively tested in the future. Standard disclaimer here.
1796 Library is not automatically build yet. But one can build it by
1797 invoking 'make' inside the libc directory.
1798 * added ADC library under libio. Preliminary version yet.
1800 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1801 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1802 aopForRemat() now and not by pic16_aopOp(),

1804 temporary registers, its a buggy feature and will be removed,
1805 * (pic16_popGet): set register instance field in AOP_CRY,

1807 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1808 * (pic16_storeForReturn): optimized return of 0,
1809 * (genCmp): experimental code for new genCmp which uses PIC18's
1810 special compare&skip instructions. Initial tests fail some times
1811 with variables grater than 1 byte in size, so new code is disabled,
1812 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1814 * (genCast): began a fix to optimize the casting of a bit to another
1815 bit, now assigning a bitfield to another bitfield will fail, sorry,
1816 * src/pic16/main.c: disabled the use of lr-support feature,
1817 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1818 * added some function prototypes, added function _debugf prototype,
1819 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1820 bits with offset (case PO_GPR_BIT),
1821 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1823 * (isBankInstruction): modified to return 0 for no banking instruction,
1824 and 1 for banking instruction,
1825 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1826 caused stop processing pCodes after a inline assembly block,
1827 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1828 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1829 registers when it shouldn't,
1830 * src/pic16/ralloc.c (allocReg): add preliminary support for
1831 supporting a limited set of temporary registers,
1833 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1835 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1836 genDataPointerSet): ensure assignments always copy in MSB to LSB
1838 (loadRegFromAop): recognize CLRH optimization,
1839 (genFunction): optimize RECEIVE iCodes in reentrant functions
1841 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1843 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1844 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1846 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4841 loaded with the linker search paths (-L arguments) and the libraries
4842 to be linked with the current source (-l arguments). Changes
4843 currently will affect only the pic16 port.
4844 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4845 include path the port specific paths and port specific libraries,
4846 * gplink command now contains the $3 argument,

4862 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4864 Documenting changes from previous commits.
4865 * configure.in (version 1.56),
4866 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4867 when generating output files to configure the pic16 library,
4868 but now I've commented it out, since gputils aren't installed in the
4869 SF compile farm, so library won't compile
4871 * device/lib/Makefile.in (version 1.56): initially I've added in
4872 target 'all' the prerequestive 'model-pic16' so it compiled the
4873 pic16 library, but now I've commented it out for the same reasons
4875 * added targets 'model-pic16' and 'objects-pic16' to compile the
4877 * added target 'port-specific-objects-pic16' to handle the
4878 generated libraries and copy them into the build/ directory
4879 * added target 'clean-intermediate-pic16' to clean intermediate
4880 files into pic16 directory
4881 * in target 'installdirs' added line to create directory pic16 in
4882 the installation path
4884 * device/include/Makefile.in (version 1.11): in target 'install'
4885 added lines to copy all header files to installation path,
4886 * in target 'installdirs' added line create directory for pic16
4887 headers in the installation path
4889 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4902 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4903 option so that it actually works. Made it specific to the z80, since
4904 the gbz80 doesn't have these kinds of I/O ports.
4906 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4908 * device/include/z180.h,

4914 * device/lib/_strcmp.c,
4915 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
4916 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4917 portmode; added deprecation warning for bank= and protmode= forms.
4918 Also, guard against buffer overflow.
4919 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4921 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4923 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4924 changed interrupt vector table generation to only emit declared vectors.
4925 * device/include/Makefile.in: added missing backslash
4926 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4928 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4930 Mainly changes to support compilation of the device libraries
4931 * src/pic16/device.c: stack is allocated via symbol and not
4932 via literal number. The symbol is placed in the corresponding
4933 position of the data ram
4934 * (pic16_dump_section): relocatable and absolute uninitialized
4935 data are now emitted in sorted order to reduce section naming,
4936 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4937 weren't marked as being in the access bank,
4939 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4941 Added portion of GNU PIC Library under the directory
4942 device/include/pic16 and device/lib/pic16. These files
4943 contain the declarations of SFRs for the PIC18Fxx2 devices.
4944 The directory is initialized via configure from toplevel.
4946 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4948 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4949 the spilllocations to be compared correctly
4951 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4953 * src/SDCCast.c (decorateType): fixed bug introduced today
4955 2004-01-12 Borut Razem <borut.razem AT siol.net>

4971 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4973 * doc/sdccman.lyx: Moved and added some sections, small changes
4974 all over. Telling LaTeX to be less strict with word spacing
4975 to better keep the right margin. Changed some notes about
4976 maintainance of the ports in section 3.2.1 - is it OK like this?
4978 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5015 UPPER for immediate operands,
5016 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5018 * src/pic16/peeph.def: all peepholes with movff are commented out,
5019 because there is a problem in the pcode peep optimizer,
5020 * src/pic16/ralloc.c: the register allocator can now reuse local
5021 function symbols for another function. This saves register usage.
5022 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5024 Added file src/pic16/NOTES with information about program writing on
5025 the current port version.

5057 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5060 * src/z80/main.c: added missed needLinkerScript flags (more than
5061 one port structure defined in these file)
5062 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5078 needLinkerScript flag
5080 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5081 * src/pic/glue.c: added variable udata_section_name to
5082 override default uninitialized data segment definition for
5083 devices only with SHAREBANK memory (reported from Erik Epetrich)
5084 * (pic14emitOverlay): modified to emit a commented overlay segment
5085 directive when no overlay data exist
5086 * (picglue): modified to emit uninitialized data segment
5087 according to udata_section_name

5097 2004-01-07 Borut Razem <borut.razem AT siol.net>
5099 * support/scripts/sdcc.nsi: update PATH
5100 * support/scripts/sdcc.ico: craeted

5113 include information about variables allocated to the overlay
5116 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5118 * as/mcs51/lkmain.c: Help about -Y option

5130 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5132 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5133 (default behaviour).
5135 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5137 A python script to validate compiler diagnostic messages. It can be
5138 used to verify that sdcc complains about bad c source code and
5139 gives a good location of the error.
5140 * support/valdiag/Makefile,
5141 * support/valdiag/valdiag.py,
5142 * support/valdiag/tests/*
5144 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5157 * src/common.h: added ifndef/define/endif macros
5158 around the header file.
5159 Bug reported from Jesus Calvino-Fraga
5161 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5163 * sdcc.spec: updated
5164 * device/include/Makefile.in: don't install CVS directories
5165 * device/lib/Makefile.in: added removal of CVS directories after install
5166 * doc/Makefile: fixed install, added local_icons
5167 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5168 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5169 * src/ds390/gen.c (genRightShift): fixed bug #870788
5170 * src/SDCCast.c (decorateType): fixed bug #870781
5172 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5174 PIC16 port related changes:
5175 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5176 added variable stackPos,
5178 * gen.c: genCall, assignResultValue: added support for
5179 pushing/retrieving function parameters to/from stack,
5180 genFunction,genEndFunction: setup stack frame for the
5182 genAddrOf: will be changed according to bug 863624
5184 * added files genutils.c and genutils.h which contain gen*
5185 debugged and optimised functions extracted from gen.c
5187 * glue.c: added variable 'externs' which holds extern symbols,
5188 pic16emitRegularMap: is modified to properly handle relocatable
5189 symbols under the new scheme,
5190 pic16createInterruptVect: is modified
5191 pic16printPublics: is modified to emit 'global' assembler directives,
5192 added pic16_printExterns to print extern symbols,
5193 pic16glue: initializes stack/frame pointer in the beginning of
5194 the assembly output. Temporary hack, will be corrected later,
5195 because gplink yet does not support stack and SDCC does not
5196 yet support a type of crt0.o object to create the final binary.
5198 * Removed many lines that contain 8051 legacy code.
5199 * The code is finally placed under a 'code' directive.
5200 * Added port specific options.
5202 * _process_pragma: simplified since now we do not need *special*
5203 include file to define SFR registers. But a separate header
5204 will be needed. This will be developed later.
5205 * _pic16_parseOptions: added, parses port specific options:
5206 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5207 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5208 --preplace-udata-with=
5210 * _pic16_setDefaultOptions: modified to initialize section names,
5211 but hack is temporarly out of order since it needs improvement.
5212 * _pic16_genAssemblerPreamble: configuration words are emitted by
5213 their address instead of their name. This part is incomplete and
5214 supports only the 18Fxx2 devices. Other devices will emit an error
5215 during assembly since they do not contain the same set of config
5217 * _pic16_genIVT: is modified,
5219 * pcode.c: added definitions for some hardware registers that are needed
5221 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5222 All PCI entries are updated. Now LFSR is supported.
5223 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5224 * added pic16_newpCodeOpLit2 to support instructions with
5225 two literal arguments
5226 * pic16_pCode2str: corrected code that emits assembler instructions
5227 with two literal operands and those that have an access bit modifier
5228 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5229 this fixes a bug which caused some labels to be lost, when an
5230 assembler directive was added, i.e. banksel,
5231 * pic16_FixRegisterBanking: improved logic that causes the insertion
5233 * InlineFunction: functions that are called once, are not any more
5234 inlined. This can be a port option in the future,
5236 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5238 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5239 hold the corresponding uninitialized symbols,
5240 * pic16_allocProcessorRegister: registers have explicit marked the
5242 * pic16_allocInternalRegister: registers are explicit marked as
5244 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5245 processing list, so bit registers were lost,
5248 * ralloc.h: added field 'accessBank' and original symbol operand
5249 in register definition,
5250 * removed the field isMapped from register definition,
5252 ** Several functions have been removed from various sources:
5253 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5254 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5255 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5256 pic16_assignRelocatableRegisters
5258 ** others have been introduced:
5259 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5260 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5262 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5264 * support/scripts/inc2h.pl: changed definition of BIT_AT
5265 to emit 'sbit at' instead of 'bit at'. This was a request.
5267 PIC16 port related preliminary changes:
5268 * gen.c: prefixed function popRegFromString with
5269 pic16_ and all references to it corrected
5270 * pcode.c: all pic16_pc_* hardware registers prefixed
5271 with underscore (_),
5272 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5273 * ralloc.c: newReg(): when register is REG_SFR then
5274 set address to rIdx,
5275 pic16_allocProcessorRegister(): marks register wasUsed=0
5276 pic16_writeUsedRegs(): added a call to assign processor
5277 registers via pic16_assignFixedRegisters
5279 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5281 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5282 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5283 variables in unused register banks. Also the SSEG is placed
5284 wherever there is enough space for it, and IDATA can be anywhere
5285 in internal RAM. For now compile using -Wl-Y[stack_size].
5286 The mem file is different for this option as well, since it
5287 makes no sense of talking about DSEG lenght.
5289 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5291 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5292 in certain cases, e.g. when ROM assignment, patch provided
5293 from Albert den Haan.
5295 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5848 not occur if the control variable is involved with a
5849 relational operator.

6338 A few small changes that speed up the peephole optimizer.
6342 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6344 Try to make the peephole optimizer smarter by maintaining
6345 an association between the assembly source code and the
6346 iCodes that originated them. Put this information to use
6347 with a new peephole rule condition "notVolatile" so that
6348 the rules can be aggressive yet still safe.
6353 * src/mcs51/peeph.def
6355 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6359 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6360 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6361 if the left or right operand symbols have the accuse flag set.
6363 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6365 Changed the type of the result of the ! (NOT) operator to char;
6366 previously it returned the same type as the source. This allows
6367 us to eliminate all the genFloatNot functions (all of its target
6368 implementations were very buggy) since !float can use the same
6371 * src/SDCCicode.c (ast2iCode): ! returns char

6380 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6381 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6382 during interrupts. Ensure WSAVE is located at a shared bank address.
6383 2. Fixed page selection in some places
6384 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6385 the registers name strings.
6386 4. Fixed "signed / unsigned compare" compiler warnings.
6387 5. The PIC port manages its own allocation of the general purpose
6388 registers, but makes no attempt to reuse them. As a result when
6389 compiling it soon runs out of general purpose registers. Some
6390 additional code was added to the files pcode.c and device.c to walk
6391 through the function call tree and rename the registers so that they
6401 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6408 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6410 Made bitfield a distinct type from bit so that bitfields
6411 convert as per ANSI C and bits retain their traditional
6412 boolean style behaviour. Implemented bitfield support in
6420 * src/ds390/gen.c: bit v bitfield split
6421 * src/z80/gen.c: New support for bitfields
6422 * support/regression/tests/bitfields.c: reenabled z80,
6425 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6427 Rules 246.x, 247.x relate to bitfields, the others speed up
6428 access to xdata mapped I/O devices.
6430 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6432 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6434 Cleaned up genPackBits and genUnpackBits and added two helper
6435 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6436 for literal assignments in genPackBits (thanks to Frieder for
6442 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6444 Fixed bug #748310 (pointer to function type mishandled when the
6445 function name is omitted). Also fixed a SIGSEGV when a function
6446 attribute (reentrant, etc) is used on a non-function or on a
6447 function but misplaced before the parameter list.

6474 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6476 Made the constant following the "interrupt" keyword optional. If
6477 omitted, the function will not automatically be given an entry
6478 in the interrupt vector table (similar to #pragma NOIV, but
6479 less syntacticly kludgy). The interrupt number is also now
6480 range checked. Also fixed a bug in the high order bit example

6956 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6957 the regression tests I'm not brave enough to enable 245.b, 245.c
6958 * doc/sdccman.lyx: added latex preamble for hyperref package.
6959 Using pdflatex this will give you a hyperlinked pdf file with
6960 bookmarks. (prepend '%' before /usepackage if this breaks something)

7007 added --disable-pic16-port
7008 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7009 * src/SDCCmain.c: linkOptions is changed to set *,
7010 added if/endif conditional macros to remove options help
7011 messages from optionsTable when a port is not configured, added
7012 support for the PIc16 port in the ports table, when executing
7013 the compiler with no port specified on command line, a default
7014 port is selected with the new macro DEFAULT_PORT which is
7015 defined in port.h, in setDefaultOptions() linkOptions is removed
7016 from initialization assignment, since now it is a set,
7017 parseCmdLine uses setParseWithComma for linkOptions, in
7018 linkEdit() linkOptions are accessed with new function indexSet()
7019 which returns the i'th item of a set variable. See SDCCset.c, in
7020 linkEdit() when calling buildCmdLine(), added linkOptions as
7021 last argument. Now users can pass arguments to gplink via the
7022 -Wl option, main() uses pic16glue() to glue up pic16 programs
7023 * src/SDCCpeeph.c: various changes to support pic16

7034 * src/pic16/glue.c: commented out some error producing lines
7035 * src/pic16/main.c: __config directives are commented out to stop
7036 gpasm complaining and test the linkage with gplink, _linkCmd and
7037 _asmCmd changed to be more gplink and gpasm friendly
7038 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7039 produced an error when parsed, peep rule 12 is added to utilize
7040 movff, but it is commented out since the pCode does not support
7041 yet a command with 2 address arguments
7043 2003-05-18 <johan AT balder>
7045 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7070 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7072 2003-05-11 Borut Razem <borut.razem AT siol.net>
7074 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7075 the path of bin directory, so that PATH is the only env. variable, which has to be set
7076 in case of standard installation.
7077 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8080 * src/SDCCicode.c: fixed array add
8082 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8083 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8084 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8086 2003-01-04 <johan AT balder>
8088 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8090 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8091 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8101 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8103 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8104 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8106 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8108 * in \sdcc\as\mcs51\ changed these files in order to create an
8109 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8110 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8111 following files to include the previous two files: aslink.dsp,
8112 Makefile.aslink, Makefile.bcc, and Makefile.in.
8114 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8115 .adb instead of .cdb
8117 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8119 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8120 value from option --iram-size.
8122 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8124 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8127 2002-09-18 <wiml AT hhhh.org>
8129 * SDCClrange.h: exposed setFromRange() and setToRange()
8130 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8131 packRegsForAccUse() (bug 542397)
8132 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8133 multiple times and emitting the fetch operations more than once
8134 added aopGetUsesAcc() function to allow binary operators to
8135 fetch their operands in the correct order; made genMinus() emit
8136 compact code for X = LITERAL - Y
8138 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8139 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8140 sprintf() in line 1267.
8142 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8143 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8146 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8147 Changes to aslink (All the changes are marked with 'JCF'):
8149 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8152 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8153 area BSEG. Also moves, if possible, the DATA area down into the internal
8154 ram so more space is available.
8156 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8159 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8160 not bytes. Function summary() which creates a memory usage summary
8161 file with extension .mem. Reports of overlaping stack and small stack
8162 size. If the space for the stack is less than 16 bytes aslink trows a
8165 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8166 the 8051. Option 'y' for memory summary output file.
8168 Changes to sdcc (All the changes are marked with 'JCF'):
8170 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8172 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8173 overlaying area for it (uses RegBankUsed[4]).
8175 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8176 bank zero as used by default. By default aslink locates the stack
8177 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8178 the creation of the .mem file. Delegates the allocation of data area
8179 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8180 the begining of the stack area to aslink.
8182 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8183 glue() in SDCCglue.c creates an area for it.
8185 2002-09-03 Borut Razem <borut.razem AT siol.net>
8186 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8187 sdcc/src/pic/glue.c:
8188 introduced atexit() handler for teporay files removal in case of
8189 errors, assertions, ...
8191 2002-08-29 Borut Razem <borut.razem AT siol.net>
8192 * sdcc/support/cpp2/auto-host_vc_in.h:
8193 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8194 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8195 Maybe there is a similar problem with BORLANDC? It should be checked!
8197 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8198 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8199 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8200 was not executed, and the compiler (cl) launched a warning:
8201 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8203 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8204 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8206 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8207 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8209 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8210 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8211 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8212 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8213 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8214 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8215 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8216 - added Release configuration in VS projects
8217 - review of compiler an linker options
8218 - VC .exe files are generated in bin_vc directory, not to interfere
8219 with binaries generated from other projects (cygwin, mingw, bcc ...)
8221 * sdcc/src/yacc.dsp: added
8223 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8224 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8225 and insert the version number definitions from .version
8227 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8229 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8230 added - genarate auto-host.h using auto-host_vc_in.h as template
8233 removed from CVS, generated automatically
8235 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8236 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8238 2002-08-11 Borut Razem <borut.razem AT siol.net>
8239 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8241 2002-08-10 Borut Razem <borut.razem AT siol.net>
8242 * src/SDCCmain.c (main):
8243 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8244 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8245 The consequence was that some temporary files were not removed.
8248 unification of code in functions tempfilename() and tempfile():
8249 function tempnam() is defined in Visual Studio 6.0 and .NET
8251 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8253 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8254 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8255 - removed compiler command line option /WX: Treats all warnings as errors
8256 - update a list of source files, included into the project
8258 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8259 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8260 changed project type to Generic Project so that can be correcly converted to VS.NET project

8272 added newline in the def file to keep MSC compiler satisfied
8274 * sdcc/src/z80/gen.c:
8275 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8276 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8277 - solved MSC error in function aopDump()

8456 * sdcc/src/SDCCloop.c:
8457 Previous fix was not good. basic blocks that have "break" or "return" are
8458 not really partof a loop , but live ranges used in these blocks should
8459 be live thru the entire loop, so set partOfLoop but don't add them to
