949 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
950 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
951 always available in leading double underscore form. The C99 support is
952 mostly missing, but it's a start.
953 * support/regression/tests/bug-227710.c: fixed nonconforming use of
954 reserved identifier "__data".
956 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1002 2005-03-20 Borut Razem <borut.razem AT siol.net>
1004 * support/scripts/inc2h.pl: WIN32 port

1032 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1034 * device/lib/printf_large.c: removed inline assembly for portability and
1035 readability. Use printf_fast if speed or size are more important.
1036 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1037 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1039 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1041 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1042 prevent compiler warning
1044 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1046 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1047 moved to level 0 and declared as static. Also they are explicit
1048 placed in access bank. This was necessery because some times they
1049 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1050 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1051 optimizations. Currently only compare to unsigned char is implemented,
1052 * src/pic16/gen.c: added fReturnIdx array,
1053 * (struct resolvedIfx) is moved to gen.h and made public,
1054 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1055 * (aopForSym): added an optimization to directly store in stack of
1056 the operand of a SEND iCode,
1057 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1058 but as registers instead (AOP_REG) using the fReturnIdx array,
1059 * (pic16_freeAsmop): remove the freed register from the
1060 _G.sregsAlloc field,
1061 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1062 a compare of 'WREG',
1063 * (pic16_popGetTempRegCond): changed function prototype, now
1064 function takes also a bitVector argument v which holds the current
1065 set of registers that are allocated for stack access by aopForSym,
1066 registers allocated in aopForSym for accessing stack symbols are not
1067 any more part of the functions usedRegs field,
1068 * (genCall): some times aopOp is called for a stack variable to be
1069 send, aopForSym might perform the push, if this is true make sure
1070 that genCall doesn't push the variable twice by testing _G.resDirect,
1071 * (genFunction): changed testing for unspecified interrupt number
1072 from 256 to INTNO_UNSPEC,
1073 * modified selection scheme of frame pointer generation. Previously
1074 if function did use local registers a frame pointer was generated,
1075 now a frame pointer is generated only if function has arguments
1076 (that need PLUSW2 register access), or has stack arguments, or the
1077 compiler is not instructed to omit the frame pointer,
1078 * (genEndFunction): before restoring local registers that were saved
1079 in the function preamble, also restore the registers that *might*
1080 have been allocated for stack access,
1081 * (genRet): removed some old comments,
1082 * (genCmp, the active (RN's) version): added a call to the
1083 pic16_genCmp_special function to perform the compare with a more
1084 robust and optimized way,
1085 * (genInline): a feature has been added in inline code generation,
1086 which allows a wildcard variable substitution when writing inline
1087 assembly. Code is incomplete and experimental therefore undocumented,
1088 * (genCast): changed order of aopOp for result and right to allow
1089 aopForSym to directly load the result if possible,
1090 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1091 perform an optimized compare on some selected special occasions,
1092 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1093 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1094 generate an IVT any more,
1095 * src/pic16/main.c (pic16_optionsTable): added command line option
1097 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1098 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1100 * src/pic16/NOTES: Raphael Neider added in list of active developers
1101 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1102 jumptable_end to prevent bug #,
1103 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1104 inCond and outCond fields,
1105 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1106 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1107 turn off register spilling,
1108 * (packRegsForOneUse): synced with other ports' versions although it
1109 is not used currently,
1110 * (pic16_packRegisters): added an optimization while reading
1111 structure bitfields, some registers may be saved (malloc code is
1112 decreased by 80 bytes)
1114 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1116 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1117 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1118 this can be optimized more?
1120 2005-03-10 Raphael Neider <rneider AT web.de>
1122 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1123 genNearPointerGet): (hopefully) fixed access to bitfields via
1124 pointers (p->bitN = x; and x = p->bitN; failed)
1126 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1169 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1170 to keep the correct label reference count when adding/removing references
1171 to labels. A peephole file using this is appended to patch #1144962.

1303 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1304 (sizeof(sectNames) changed to sizeof(sectName))

1312 of (byte sized) temporaries (assign them to WREG for now)
1313 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1314 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1315 this might fix SIGSEGVs on MinGW...
1316 * src/SDCCopt.c (killDeadCode): restored original behaviour
1317 (volatile operands might get thrown away though)
1319 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1321 * src/pic16/gen.c: fixed bug #1106975,

1760 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1761 Now 4 algorithms for mcs51 jumptable generation are used:
1762 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1763 addresses loaded pc-relative for up to 112 cases and stack-pushing
1764 target addresses loaded with offset from dptr for up to 256 cases.
1766 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1767 * src/mcs51/main.c: adapted constants for switch table generation
1768 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1772 * device/lib/printf_large.c (_print_format): fixed bug 1073386
1773 * support/regression/tests/bug1057979.c: added test for bug 1073386
1775 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1777 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
1780 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1782 * src/pic16/device.h,
1783 * src/pic16/genarith.c,
1786 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1788 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1790 Large cummulative patch for pic16 port.
1791 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1792 to call when a stack overflow occurs,
1793 * (malloc.h): added CVS Id tag,
1794 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1796 * added libc directory. The current version of LibC contains string
1797 functions, ctype functions and macros and some functions of the
1798 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1799 be extensively tested in the future. Standard disclaimer here.
1800 Library is not automatically build yet. But one can build it by
1801 invoking 'make' inside the libc directory.
1802 * added ADC library under libio. Preliminary version yet.
1804 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1805 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1806 aopForRemat() now and not by pic16_aopOp(),
1807 * (pic16_popGetTempReg): removed warning messgae when allocating
1808 temporary registers, its a buggy feature and will be removed,
1809 * (pic16_popGet): set register instance field in AOP_CRY,
1810 * (pic16_outBitC): fixed for results in size greater than 1,
1811 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1812 * (pic16_storeForReturn): optimized return of 0,
1813 * (genCmp): experimental code for new genCmp which uses PIC18's
1814 special compare&skip instructions. Initial tests fail some times
1815 with variables grater than 1 byte in size, so new code is disabled,
1816 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1818 * (genCast): began a fix to optimize the casting of a bit to another
1819 bit, now assigning a bitfield to another bitfield will fail, sorry,
1820 * src/pic16/main.c: disabled the use of lr-support feature,
1821 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1822 * added some function prototypes, added function _debugf prototype,
1823 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1824 bits with offset (case PO_GPR_BIT),
1825 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1827 * (isBankInstruction): modified to return 0 for no banking instruction,
1828 and 1 for banking instruction,
1829 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1830 caused stop processing pCodes after a inline assembly block,
1831 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1832 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1833 registers when it shouldn't,
1834 * src/pic16/ralloc.c (allocReg): add preliminary support for
1835 supporting a limited set of temporary registers,
1837 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1839 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1840 genDataPointerSet): ensure assignments always copy in MSB to LSB
1842 (loadRegFromAop): recognize CLRH optimization,
1843 (genFunction): optimize RECEIVE iCodes in reentrant functions
1845 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1847 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1848 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1850 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1857 * device/lib/_gptrgetc.c (_gptrgetc),
1858 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1859 instead of sjmp to ret
1860 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1861 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1863 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4845 loaded with the linker search paths (-L arguments) and the libraries
4846 to be linked with the current source (-l arguments). Changes
4847 currently will affect only the pic16 port.
4848 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4849 include path the port specific paths and port specific libraries,

4868 Documenting changes from previous commits.
4869 * configure.in (version 1.56),
4870 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4871 when generating output files to configure the pic16 library,
4872 but now I've commented it out, since gputils aren't installed in the
4873 SF compile farm, so library won't compile
4875 * device/lib/Makefile.in (version 1.56): initially I've added in
4876 target 'all' the prerequestive 'model-pic16' so it compiled the
4877 pic16 library, but now I've commented it out for the same reasons
4879 * added targets 'model-pic16' and 'objects-pic16' to compile the
4881 * added target 'port-specific-objects-pic16' to handle the
4882 generated libraries and copy them into the build/ directory
4883 * added target 'clean-intermediate-pic16' to clean intermediate
4884 files into pic16 directory
4885 * in target 'installdirs' added line to create directory pic16 in
4886 the installation path
4888 * device/include/Makefile.in (version 1.11): in target 'install'
4889 added lines to copy all header files to installation path,
4890 * in target 'installdirs' added line create directory for pic16
4891 headers in the installation path
4893 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4906 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4907 option so that it actually works. Made it specific to the z80, since
4908 the gbz80 doesn't have these kinds of I/O ports.
4910 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4912 * device/include/z180.h,

4920 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4921 portmode; added deprecation warning for bank= and protmode= forms.
4922 Also, guard against buffer overflow.
4923 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4925 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4927 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4928 changed interrupt vector table generation to only emit declared vectors.
4929 * device/include/Makefile.in: added missing backslash
4930 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

4934 Mainly changes to support compilation of the device libraries
4935 * src/pic16/device.c: stack is allocated via symbol and not
4936 via literal number. The symbol is placed in the corresponding
4937 position of the data ram
4938 * (pic16_dump_section): relocatable and absolute uninitialized
4939 data are now emitted in sorted order to reduce section naming,
4940 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4941 weren't marked as being in the access bank,
4943 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4945 Added portion of GNU PIC Library under the directory
4946 device/include/pic16 and device/lib/pic16. These files
4947 contain the declarations of SFRs for the PIC18Fxx2 devices.
4948 The directory is initialized via configure from toplevel.
4950 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4952 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4953 the spilllocations to be compared correctly
4955 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4957 * src/SDCCast.c (decorateType): fixed bug introduced today
4959 2004-01-12 Borut Razem <borut.razem AT siol.net>

4975 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4977 * doc/sdccman.lyx: Moved and added some sections, small changes
4978 all over. Telling LaTeX to be less strict with word spacing
4979 to better keep the right margin. Changed some notes about
4980 maintainance of the ports in section 3.2.1 - is it OK like this?
4982 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5019 UPPER for immediate operands,
5020 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5022 * src/pic16/peeph.def: all peepholes with movff are commented out,
5023 because there is a problem in the pcode peep optimizer,
5024 * src/pic16/ralloc.c: the register allocator can now reuse local
5025 function symbols for another function. This saves register usage.
5026 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5028 Added file src/pic16/NOTES with information about program writing on
5029 the current port version.

5058 gen51Code): more efficient parameter receive for --model-large
5061 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5064 * src/z80/main.c: added missed needLinkerScript flags (more than
5065 one port structure defined in these file)
5066 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5082 needLinkerScript flag
5084 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5085 * src/pic/glue.c: added variable udata_section_name to
5086 override default uninitialized data segment definition for
5087 devices only with SHAREBANK memory (reported from Erik Epetrich)
5088 * (pic14emitOverlay): modified to emit a commented overlay segment
5089 directive when no overlay data exist
5090 * (picglue): modified to emit uninitialized data segment
5091 according to udata_section_name

5101 2004-01-07 Borut Razem <borut.razem AT siol.net>
5103 * support/scripts/sdcc.nsi: update PATH
5104 * support/scripts/sdcc.ico: craeted

5117 include information about variables allocated to the overlay
5120 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5122 * as/mcs51/lkmain.c: Help about -Y option

5134 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5136 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5137 (default behaviour).
5139 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5141 A python script to validate compiler diagnostic messages. It can be
5142 used to verify that sdcc complains about bad c source code and
5143 gives a good location of the error.
5144 * support/valdiag/Makefile,
5145 * support/valdiag/valdiag.py,
5146 * support/valdiag/tests/*
5148 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5163 Bug reported from Jesus Calvino-Fraga
5165 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5167 * sdcc.spec: updated
5168 * device/include/Makefile.in: don't install CVS directories
5169 * device/lib/Makefile.in: added removal of CVS directories after install
5170 * doc/Makefile: fixed install, added local_icons
5171 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5172 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5173 * src/ds390/gen.c (genRightShift): fixed bug #870788
5174 * src/SDCCast.c (decorateType): fixed bug #870781
5176 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5178 PIC16 port related changes:
5179 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5180 added variable stackPos,
5182 * gen.c: genCall, assignResultValue: added support for
5183 pushing/retrieving function parameters to/from stack,
5184 genFunction,genEndFunction: setup stack frame for the
5186 genAddrOf: will be changed according to bug 863624
5188 * added files genutils.c and genutils.h which contain gen*
5189 debugged and optimised functions extracted from gen.c
5191 * glue.c: added variable 'externs' which holds extern symbols,
5192 pic16emitRegularMap: is modified to properly handle relocatable
5193 symbols under the new scheme,
5194 pic16createInterruptVect: is modified
5195 pic16printPublics: is modified to emit 'global' assembler directives,
5196 added pic16_printExterns to print extern symbols,
5197 pic16glue: initializes stack/frame pointer in the beginning of
5198 the assembly output. Temporary hack, will be corrected later,
5199 because gplink yet does not support stack and SDCC does not
5200 yet support a type of crt0.o object to create the final binary.
5202 * Removed many lines that contain 8051 legacy code.
5203 * The code is finally placed under a 'code' directive.
5204 * Added port specific options.
5206 * _process_pragma: simplified since now we do not need *special*
5207 include file to define SFR registers. But a separate header
5208 will be needed. This will be developed later.
5209 * _pic16_parseOptions: added, parses port specific options:
5210 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5211 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5212 --preplace-udata-with=
5214 * _pic16_setDefaultOptions: modified to initialize section names,
5215 but hack is temporarly out of order since it needs improvement.
5216 * _pic16_genAssemblerPreamble: configuration words are emitted by
5217 their address instead of their name. This part is incomplete and
5218 supports only the 18Fxx2 devices. Other devices will emit an error
5219 during assembly since they do not contain the same set of config
5221 * _pic16_genIVT: is modified,
5223 * pcode.c: added definitions for some hardware registers that are needed
5225 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5226 All PCI entries are updated. Now LFSR is supported.
5227 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5228 * added pic16_newpCodeOpLit2 to support instructions with
5229 two literal arguments
5230 * pic16_pCode2str: corrected code that emits assembler instructions
5231 with two literal operands and those that have an access bit modifier
5232 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5233 this fixes a bug which caused some labels to be lost, when an
5234 assembler directive was added, i.e. banksel,
5235 * pic16_FixRegisterBanking: improved logic that causes the insertion
5237 * InlineFunction: functions that are called once, are not any more
5238 inlined. This can be a port option in the future,
5240 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5242 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5243 hold the corresponding uninitialized symbols,
5244 * pic16_allocProcessorRegister: registers have explicit marked the
5246 * pic16_allocInternalRegister: registers are explicit marked as
5248 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5249 processing list, so bit registers were lost,
5252 * ralloc.h: added field 'accessBank' and original symbol operand
5253 in register definition,
5254 * removed the field isMapped from register definition,
5256 ** Several functions have been removed from various sources:
5257 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5258 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5259 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5260 pic16_assignRelocatableRegisters
5262 ** others have been introduced:
5263 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5264 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5266 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5268 * support/scripts/inc2h.pl: changed definition of BIT_AT
5269 to emit 'sbit at' instead of 'bit at'. This was a request.
5271 PIC16 port related preliminary changes:
5272 * gen.c: prefixed function popRegFromString with
5273 pic16_ and all references to it corrected
5274 * pcode.c: all pic16_pc_* hardware registers prefixed
5275 with underscore (_),
5276 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5277 * ralloc.c: newReg(): when register is REG_SFR then
5278 set address to rIdx,
5279 pic16_allocProcessorRegister(): marks register wasUsed=0
5280 pic16_writeUsedRegs(): added a call to assign processor
5281 registers via pic16_assignFixedRegisters
5283 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5285 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5286 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5287 variables in unused register banks. Also the SSEG is placed
5288 wherever there is enough space for it, and IDATA can be anywhere
5289 in internal RAM. For now compile using -Wl-Y[stack_size].
5290 The mem file is different for this option as well, since it
5291 makes no sense of talking about DSEG lenght.
5293 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5295 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5296 in certain cases, e.g. when ROM assignment, patch provided
5297 from Albert den Haan.
5299 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6350 iCodes that originated them. Put this information to use
6351 with a new peephole rule condition "notVolatile" so that
6352 the rules can be aggressive yet still safe.
6357 * src/mcs51/peeph.def
6359 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6363 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6364 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6365 if the left or right operand symbols have the accuse flag set.
6367 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6369 Changed the type of the result of the ! (NOT) operator to char;
6370 previously it returned the same type as the source. This allows
6371 us to eliminate all the genFloatNot functions (all of its target
6372 implementations were very buggy) since !float can use the same
6375 * src/SDCCicode.c (ast2iCode): ! returns char

6384 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6385 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6386 during interrupts. Ensure WSAVE is located at a shared bank address.
6387 2. Fixed page selection in some places
6388 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6389 the registers name strings.
6390 4. Fixed "signed / unsigned compare" compiler warnings.
6391 5. The PIC port manages its own allocation of the general purpose
6392 registers, but makes no attempt to reuse them. As a result when
6393 compiling it soon runs out of general purpose registers. Some
6394 additional code was added to the files pcode.c and device.c to walk
6395 through the function call tree and rename the registers so that they
6405 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6412 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6414 Made bitfield a distinct type from bit so that bitfields
6415 convert as per ANSI C and bits retain their traditional
6416 boolean style behaviour. Implemented bitfield support in
6424 * src/ds390/gen.c: bit v bitfield split
6425 * src/z80/gen.c: New support for bitfields
6426 * support/regression/tests/bitfields.c: reenabled z80,
6429 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6431 Rules 246.x, 247.x relate to bitfields, the others speed up
6432 access to xdata mapped I/O devices.
6434 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6436 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6438 Cleaned up genPackBits and genUnpackBits and added two helper
6439 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6440 for literal assignments in genPackBits (thanks to Frieder for
6446 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6448 Fixed bug #748310 (pointer to function type mishandled when the
6449 function name is omitted). Also fixed a SIGSEGV when a function
6450 attribute (reentrant, etc) is used on a non-function or on a
6451 function but misplaced before the parameter list.

6478 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6480 Made the constant following the "interrupt" keyword optional. If
6481 omitted, the function will not automatically be given an entry
6482 in the interrupt vector table (similar to #pragma NOIV, but
6483 less syntacticly kludgy). The interrupt number is also now
6484 range checked. Also fixed a bug in the high order bit example

6505 unsigned, but are signed by default
6506 * src/SDCCval.c (constVal): rearranged
6507 * src/SDCCval.c (valMod): preliminary fix
6508 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6941 Finalize muluint/mulsint and mululong/mulslong merging:
6942 * device/lib/_mulint.c
6943 * device/lib/_mullong.c
6944 * device/lib/gbz80/mul.s
6945 * device/lib/gbz80/stubs.s
6946 * device/lib/z80/mul.s
6947 * device/lib/z80/stubs.s
6948 * src/SDCCsymt.c (initCSupport)
6950 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6952 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
6953 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
6954 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
6955 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
6958 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6960 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6961 the regression tests I'm not brave enough to enable 245.b, 245.c
6962 * doc/sdccman.lyx: added latex preamble for hyperref package.
6963 Using pdflatex this will give you a hyperlinked pdf file with
6964 bookmarks. (prepend '%' before /usepackage if this breaks something)
6966 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6976 * src/SDCCglue.c (printIval): fixed bug #739934
6978 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
6980 Applied patch from bug 737905 (renamed yylineo to mylineno):
6987 * src/pic16/pcode.c: Cleaned warnings
6988 * src/pic16/pcodeflow.c: Cleaned warnings
6989 * src/pic16/pcoderegs.c: Cleaned warnings
6991 2003-05-19 Scott Dattalo <scott AT dattalo.com>
6993 * src/pic16/pcode.c: Cleaned warnings
6994 * src/pic16/pcodepeep.c: Cleaned warnings

7000 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7002 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7004 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7005 it can be defined with CFLAGS when running configure
7006 * src/SDCCmain.c: fixed compiling + linking with object files
7008 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7010 * configure.in: configure for pic16 port,
7011 added --disable-pic16-port
7012 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7013 * src/SDCCmain.c: linkOptions is changed to set *,
7014 added if/endif conditional macros to remove options help
7015 messages from optionsTable when a port is not configured, added
7016 support for the PIc16 port in the ports table, when executing
7017 the compiler with no port specified on command line, a default
7018 port is selected with the new macro DEFAULT_PORT which is
7019 defined in port.h, in setDefaultOptions() linkOptions is removed
7020 from initialization assignment, since now it is a set,
7021 parseCmdLine uses setParseWithComma for linkOptions, in
7022 linkEdit() linkOptions are accessed with new function indexSet()
7023 which returns the i'th item of a set variable. See SDCCset.c, in
7024 linkEdit() when calling buildCmdLine(), added linkOptions as
7025 last argument. Now users can pass arguments to gplink via the
7026 -Wl option, main() uses pic16glue() to glue up pic16 programs
7027 * src/SDCCpeeph.c: various changes to support pic16
7028 * src/SDCCset.c: added function void *indexSet(set *, int) to

7036 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7038 * src/pic16/glue.c: commented out some error producing lines
7039 * src/pic16/main.c: __config directives are commented out to stop
7040 gpasm complaining and test the linkage with gplink, _linkCmd and
7041 _asmCmd changed to be more gplink and gpasm friendly
7042 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7043 produced an error when parsed, peep rule 12 is added to utilize
7044 movff, but it is commented out since the pCode does not support
7045 yet a command with 2 address arguments
7047 2003-05-18 <johan AT balder>
7049 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7050 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7051 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

7074 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7076 2003-05-11 Borut Razem <borut.razem AT siol.net>
7078 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7079 the path of bin directory, so that PATH is the only env. variable, which has to be set
7080 in case of standard installation.
7081 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8084 * src/SDCCicode.c: fixed array add
8086 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8087 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8088 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8090 2003-01-04 <johan AT balder>
8092 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8094 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8095 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8097 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8104 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8105 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8107 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8108 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8110 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8112 * in \sdcc\as\mcs51\ changed these files in order to create an
8113 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8114 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8115 following files to include the previous two files: aslink.dsp,
8116 Makefile.aslink, Makefile.bcc, and Makefile.in.
8118 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8119 .adb instead of .cdb
8121 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8123 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8124 value from option --iram-size.
8126 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8128 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8131 2002-09-18 <wiml AT hhhh.org>
8133 * SDCClrange.h: exposed setFromRange() and setToRange()
8134 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8135 packRegsForAccUse() (bug 542397)
8136 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8137 multiple times and emitting the fetch operations more than once
8138 added aopGetUsesAcc() function to allow binary operators to
8139 fetch their operands in the correct order; made genMinus() emit
8140 compact code for X = LITERAL - Y
8142 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8143 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8144 sprintf() in line 1267.
8146 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8147 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8150 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8151 Changes to aslink (All the changes are marked with 'JCF'):
8153 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8156 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8157 area BSEG. Also moves, if possible, the DATA area down into the internal
8158 ram so more space is available.
8160 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8163 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8164 not bytes. Function summary() which creates a memory usage summary
8165 file with extension .mem. Reports of overlaping stack and small stack
8166 size. If the space for the stack is less than 16 bytes aslink trows a
8169 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8170 the 8051. Option 'y' for memory summary output file.
8172 Changes to sdcc (All the changes are marked with 'JCF'):
8174 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8176 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8177 overlaying area for it (uses RegBankUsed[4]).
8179 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8180 bank zero as used by default. By default aslink locates the stack
8181 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8182 the creation of the .mem file. Delegates the allocation of data area
8183 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8184 the begining of the stack area to aslink.
8186 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8187 glue() in SDCCglue.c creates an area for it.
8189 2002-09-03 Borut Razem <borut.razem AT siol.net>
8190 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8191 sdcc/src/pic/glue.c:
8192 introduced atexit() handler for teporay files removal in case of
8193 errors, assertions, ...
8195 2002-08-29 Borut Razem <borut.razem AT siol.net>
8196 * sdcc/support/cpp2/auto-host_vc_in.h:
8197 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8198 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8199 Maybe there is a similar problem with BORLANDC? It should be checked!
8201 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8202 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8203 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8204 was not executed, and the compiler (cl) launched a warning:
8205 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8207 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8208 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8210 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8211 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8213 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8214 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8215 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8216 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8217 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8218 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8219 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8220 - added Release configuration in VS projects
8221 - review of compiler an linker options
8222 - VC .exe files are generated in bin_vc directory, not to interfere
8223 with binaries generated from other projects (cygwin, mingw, bcc ...)
8225 * sdcc/src/yacc.dsp: added
8227 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8228 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8229 and insert the version number definitions from .version
8231 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8233 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8234 added - genarate auto-host.h using auto-host_vc_in.h as template
8237 removed from CVS, generated automatically
8239 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8240 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8242 2002-08-11 Borut Razem <borut.razem AT siol.net>
8243 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8245 2002-08-10 Borut Razem <borut.razem AT siol.net>
8246 * src/SDCCmain.c (main):
8247 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8248 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8249 The consequence was that some temporary files were not removed.
8252 unification of code in functions tempfilename() and tempfile():
8253 function tempnam() is defined in Visual Studio 6.0 and .NET

8461 Previous fix was not good. basic blocks that have "break" or "return" are
8462 not really partof a loop , but live ranges used in these blocks should
