944 on rIfx (genCmp was broken)
946 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
948 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
949 * src/z80/main.c (_keywords[]),
950 * src/SDCCglobal.h (struct options),
952 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
953 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
954 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
955 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
956 always available in leading double underscore form. The C99 support is
957 mostly missing, but it's a start.
958 * support/regression/tests/bug-227710.c: fixed nonconforming use of
959 reserved identifier "__data".
961 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1037 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1039 * device/lib/printf_large.c: removed inline assembly for portability and
1040 readability. Use printf_fast if speed or size are more important.
1041 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1042 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1044 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1046 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1047 prevent compiler warning
1049 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1051 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1052 moved to level 0 and declared as static. Also they are explicit
1053 placed in access bank. This was necessery because some times they
1054 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1055 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1056 optimizations. Currently only compare to unsigned char is implemented,
1057 * src/pic16/gen.c: added fReturnIdx array,
1058 * (struct resolvedIfx) is moved to gen.h and made public,
1059 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1060 * (aopForSym): added an optimization to directly store in stack of
1061 the operand of a SEND iCode,
1062 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1063 but as registers instead (AOP_REG) using the fReturnIdx array,
1064 * (pic16_freeAsmop): remove the freed register from the
1065 _G.sregsAlloc field,
1066 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1067 a compare of 'WREG',
1068 * (pic16_popGetTempRegCond): changed function prototype, now
1069 function takes also a bitVector argument v which holds the current
1070 set of registers that are allocated for stack access by aopForSym,
1071 registers allocated in aopForSym for accessing stack symbols are not
1072 any more part of the functions usedRegs field,
1073 * (genCall): some times aopOp is called for a stack variable to be
1074 send, aopForSym might perform the push, if this is true make sure
1075 that genCall doesn't push the variable twice by testing _G.resDirect,
1076 * (genFunction): changed testing for unspecified interrupt number
1077 from 256 to INTNO_UNSPEC,
1078 * modified selection scheme of frame pointer generation. Previously
1079 if function did use local registers a frame pointer was generated,
1080 now a frame pointer is generated only if function has arguments
1081 (that need PLUSW2 register access), or has stack arguments, or the
1082 compiler is not instructed to omit the frame pointer,
1083 * (genEndFunction): before restoring local registers that were saved
1084 in the function preamble, also restore the registers that *might*
1085 have been allocated for stack access,
1086 * (genRet): removed some old comments,
1087 * (genCmp, the active (RN's) version): added a call to the
1088 pic16_genCmp_special function to perform the compare with a more
1089 robust and optimized way,
1090 * (genInline): a feature has been added in inline code generation,
1091 which allows a wildcard variable substitution when writing inline
1092 assembly. Code is incomplete and experimental therefore undocumented,
1093 * (genCast): changed order of aopOp for result and right to allow
1094 aopForSym to directly load the result if possible,
1095 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1096 perform an optimized compare on some selected special occasions,
1097 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1098 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1099 generate an IVT any more,
1100 * src/pic16/main.c (pic16_optionsTable): added command line option
1102 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1103 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1105 * src/pic16/NOTES: Raphael Neider added in list of active developers
1106 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1107 jumptable_end to prevent bug #,
1108 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1109 inCond and outCond fields,
1110 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1111 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1112 turn off register spilling,
1113 * (packRegsForOneUse): synced with other ports' versions although it
1114 is not used currently,
1115 * (pic16_packRegisters): added an optimization while reading
1116 structure bitfields, some registers may be saved (malloc code is
1117 decreased by 80 bytes)
1119 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1121 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1122 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1123 this can be optimized more?
1125 2005-03-10 Raphael Neider <rneider AT web.de>
1127 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1128 genNearPointerGet): (hopefully) fixed access to bitfields via
1129 pointers (p->bitN = x; and x = p->bitN; failed)
1131 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1174 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1175 to keep the correct label reference count when adding/removing references
1176 to labels. A peephole file using this is appended to patch #1144962.

1308 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1309 (sizeof(sectNames) changed to sizeof(sectName))
1310 Both patches fix segfaults under MinGW.
1312 2005-01-23 Raphael Neider <rneider AT web.de>
1314 * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
1315 Safe_[mc]?alloc()'ed variables
1316 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
1317 of (byte sized) temporaries (assign them to WREG for now)
1318 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1319 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1320 this might fix SIGSEGVs on MinGW...
1321 * src/SDCCopt.c (killDeadCode): restored original behaviour
1322 (volatile operands might get thrown away though)
1324 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1326 * src/pic16/gen.c: fixed bug #1106975,

1761 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1763 Adding support for replacing ljmps with sjmps in jumptables
1764 generated for switch statements. For now you need to set the
1765 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1766 Now 4 algorithms for mcs51 jumptable generation are used:
1767 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1768 addresses loaded pc-relative for up to 112 cases and stack-pushing
1769 target addresses loaded with offset from dptr for up to 256 cases.
1771 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1772 * src/mcs51/main.c: adapted constants for switch table generation
1773 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1795 Large cummulative patch for pic16 port.
1796 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1797 to call when a stack overflow occurs,
1798 * (malloc.h): added CVS Id tag,
1799 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1801 * added libc directory. The current version of LibC contains string
1802 functions, ctype functions and macros and some functions of the
1803 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1804 be extensively tested in the future. Standard disclaimer here.
1805 Library is not automatically build yet. But one can build it by
1806 invoking 'make' inside the libc directory.
1807 * added ADC library under libio. Preliminary version yet.
1809 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1816 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1817 * (pic16_storeForReturn): optimized return of 0,
1818 * (genCmp): experimental code for new genCmp which uses PIC18's
1819 special compare&skip instructions. Initial tests fail some times
1820 with variables grater than 1 byte in size, so new code is disabled,
1821 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1823 * (genCast): began a fix to optimize the casting of a bit to another
1824 bit, now assigning a bitfield to another bitfield will fail, sorry,
1825 * src/pic16/main.c: disabled the use of lr-support feature,
1826 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1827 * added some function prototypes, added function _debugf prototype,
1828 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1829 bits with offset (case PO_GPR_BIT),
1830 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1832 * (isBankInstruction): modified to return 0 for no banking instruction,
1833 and 1 for banking instruction,
1834 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1835 caused stop processing pCodes after a inline assembly block,
1836 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1837 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1838 registers when it shouldn't,
1839 * src/pic16/ralloc.c (allocReg): add preliminary support for
1840 supporting a limited set of temporary registers,
1842 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1844 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1845 genDataPointerSet): ensure assignments always copy in MSB to LSB
1847 (loadRegFromAop): recognize CLRH optimization,
1848 (genFunction): optimize RECEIVE iCodes in reentrant functions
1850 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1852 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1853 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

1864 instead of sjmp to ret
1865 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1866 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1868 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4851 to be linked with the current source (-l arguments). Changes
4852 currently will affect only the pic16 port.
4853 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4854 include path the port specific paths and port specific libraries,

4861 initialization which bypassed the variable initializations block.
4863 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4864 COMPILE_FLAGS and added the --nostdinc option
4866 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4871 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4873 Documenting changes from previous commits.
4874 * configure.in (version 1.56),
4875 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4876 when generating output files to configure the pic16 library,
4877 but now I've commented it out, since gputils aren't installed in the
4878 SF compile farm, so library won't compile
4880 * device/lib/Makefile.in (version 1.56): initially I've added in
4881 target 'all' the prerequestive 'model-pic16' so it compiled the
4882 pic16 library, but now I've commented it out for the same reasons
4884 * added targets 'model-pic16' and 'objects-pic16' to compile the
4886 * added target 'port-specific-objects-pic16' to handle the
4887 generated libraries and copy them into the build/ directory
4888 * added target 'clean-intermediate-pic16' to clean intermediate
4889 files into pic16 directory
4890 * in target 'installdirs' added line to create directory pic16 in
4891 the installation path
4893 * device/include/Makefile.in (version 1.11): in target 'install'
4894 added lines to copy all header files to installation path,
4895 * in target 'installdirs' added line create directory for pic16
4896 headers in the installation path
4898 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4911 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4912 option so that it actually works. Made it specific to the z80, since
4913 the gbz80 doesn't have these kinds of I/O ports.
4915 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4917 * device/include/z180.h,

4923 * device/lib/_strcmp.c,
4924 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
4925 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4926 portmode; added deprecation warning for bank= and protmode= forms.
4927 Also, guard against buffer overflow.
4928 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4930 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4932 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4933 changed interrupt vector table generation to only emit declared vectors.
4934 * device/include/Makefile.in: added missing backslash
4935 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

4939 Mainly changes to support compilation of the device libraries
4940 * src/pic16/device.c: stack is allocated via symbol and not
4941 via literal number. The symbol is placed in the corresponding
4942 position of the data ram
4943 * (pic16_dump_section): relocatable and absolute uninitialized
4944 data are now emitted in sorted order to reduce section naming,
4945 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4946 weren't marked as being in the access bank,
4948 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4950 Added portion of GNU PIC Library under the directory
4951 device/include/pic16 and device/lib/pic16. These files
4952 contain the declarations of SFRs for the PIC18Fxx2 devices.
4953 The directory is initialized via configure from toplevel.
4955 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4957 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4958 the spilllocations to be compared correctly
4960 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4962 * src/SDCCast.c (decorateType): fixed bug introduced today
4964 2004-01-12 Borut Razem <borut.razem AT siol.net>

4980 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4982 * doc/sdccman.lyx: Moved and added some sections, small changes
4983 all over. Telling LaTeX to be less strict with word spacing
4984 to better keep the right margin. Changed some notes about
4985 maintainance of the ports in section 3.2.1 - is it OK like this?
4987 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5024 UPPER for immediate operands,
5025 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5027 * src/pic16/peeph.def: all peepholes with movff are commented out,
5028 because there is a problem in the pcode peep optimizer,
5029 * src/pic16/ralloc.c: the register allocator can now reuse local
5030 function symbols for another function. This saves register usage.
5031 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5033 Added file src/pic16/NOTES with information about program writing on
5034 the current port version.

5043 * src/SDCCmain.c : fixed #872250: -l command line defined library
5044 files are scanned before standard library files
5046 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5063 gen51Code): more efficient parameter receive for --model-large
5066 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5069 * src/z80/main.c: added missed needLinkerScript flags (more than
5070 one port structure defined in these file)
5071 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5087 needLinkerScript flag
5089 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5090 * src/pic/glue.c: added variable udata_section_name to
5091 override default uninitialized data segment definition for
5092 devices only with SHAREBANK memory (reported from Erik Epetrich)
5093 * (pic14emitOverlay): modified to emit a commented overlay segment
5094 directive when no overlay data exist
5095 * (picglue): modified to emit uninitialized data segment
5096 according to udata_section_name

5102 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5103 object file from '.rel' to '.o' in port->linker structure,
5104 changed size of fptr from 2 to 3 in port structure
5106 2004-01-07 Borut Razem <borut.razem AT siol.net>
5108 * support/scripts/sdcc.nsi: update PATH
5109 * support/scripts/sdcc.ico: craeted

5122 include information about variables allocated to the overlay
5125 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5127 * as/mcs51/lkmain.c: Help about -Y option

5139 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5141 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5142 (default behaviour).
5144 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5146 A python script to validate compiler diagnostic messages. It can be
5147 used to verify that sdcc complains about bad c source code and
5148 gives a good location of the error.
5149 * support/valdiag/Makefile,
5150 * support/valdiag/valdiag.py,
5151 * support/valdiag/tests/*
5153 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5166 * src/common.h: added ifndef/define/endif macros
5167 around the header file.
5168 Bug reported from Jesus Calvino-Fraga
5170 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5172 * sdcc.spec: updated
5173 * device/include/Makefile.in: don't install CVS directories
5174 * device/lib/Makefile.in: added removal of CVS directories after install
5175 * doc/Makefile: fixed install, added local_icons
5176 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5177 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5178 * src/ds390/gen.c (genRightShift): fixed bug #870788
5179 * src/SDCCast.c (decorateType): fixed bug #870781
5181 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5183 PIC16 port related changes:
5184 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5185 added variable stackPos,
5187 * gen.c: genCall, assignResultValue: added support for
5188 pushing/retrieving function parameters to/from stack,
5189 genFunction,genEndFunction: setup stack frame for the
5191 genAddrOf: will be changed according to bug 863624
5193 * added files genutils.c and genutils.h which contain gen*
5194 debugged and optimised functions extracted from gen.c
5196 * glue.c: added variable 'externs' which holds extern symbols,
5197 pic16emitRegularMap: is modified to properly handle relocatable
5198 symbols under the new scheme,
5199 pic16createInterruptVect: is modified
5200 pic16printPublics: is modified to emit 'global' assembler directives,
5201 added pic16_printExterns to print extern symbols,
5202 pic16glue: initializes stack/frame pointer in the beginning of
5203 the assembly output. Temporary hack, will be corrected later,
5204 because gplink yet does not support stack and SDCC does not
5205 yet support a type of crt0.o object to create the final binary.
5207 * Removed many lines that contain 8051 legacy code.
5208 * The code is finally placed under a 'code' directive.
5209 * Added port specific options.
5211 * _process_pragma: simplified since now we do not need *special*
5212 include file to define SFR registers. But a separate header
5213 will be needed. This will be developed later.
5214 * _pic16_parseOptions: added, parses port specific options:
5215 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5216 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5217 --preplace-udata-with=
5219 * _pic16_setDefaultOptions: modified to initialize section names,
5220 but hack is temporarly out of order since it needs improvement.
5221 * _pic16_genAssemblerPreamble: configuration words are emitted by
5222 their address instead of their name. This part is incomplete and
5223 supports only the 18Fxx2 devices. Other devices will emit an error
5224 during assembly since they do not contain the same set of config
5226 * _pic16_genIVT: is modified,
5228 * pcode.c: added definitions for some hardware registers that are needed
5230 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5231 All PCI entries are updated. Now LFSR is supported.
5232 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5233 * added pic16_newpCodeOpLit2 to support instructions with
5234 two literal arguments
5235 * pic16_pCode2str: corrected code that emits assembler instructions
5236 with two literal operands and those that have an access bit modifier
5237 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5238 this fixes a bug which caused some labels to be lost, when an
5239 assembler directive was added, i.e. banksel,
5240 * pic16_FixRegisterBanking: improved logic that causes the insertion
5242 * InlineFunction: functions that are called once, are not any more
5243 inlined. This can be a port option in the future,
5245 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5247 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5248 hold the corresponding uninitialized symbols,
5249 * pic16_allocProcessorRegister: registers have explicit marked the
5251 * pic16_allocInternalRegister: registers are explicit marked as
5253 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5254 processing list, so bit registers were lost,
5257 * ralloc.h: added field 'accessBank' and original symbol operand
5258 in register definition,
5259 * removed the field isMapped from register definition,
5261 ** Several functions have been removed from various sources:
5262 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5263 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5264 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5265 pic16_assignRelocatableRegisters
5267 ** others have been introduced:
5268 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5269 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5271 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5273 * support/scripts/inc2h.pl: changed definition of BIT_AT
5274 to emit 'sbit at' instead of 'bit at'. This was a request.
5276 PIC16 port related preliminary changes:
5277 * gen.c: prefixed function popRegFromString with
5278 pic16_ and all references to it corrected
5279 * pcode.c: all pic16_pc_* hardware registers prefixed
5280 with underscore (_),
5281 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5282 * ralloc.c: newReg(): when register is REG_SFR then
5283 set address to rIdx,
5284 pic16_allocProcessorRegister(): marks register wasUsed=0
5285 pic16_writeUsedRegs(): added a call to assign processor
5286 registers via pic16_assignFixedRegisters
5288 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5290 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5291 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5292 variables in unused register banks. Also the SSEG is placed
5293 wherever there is enough space for it, and IDATA can be anywhere
5294 in internal RAM. For now compile using -Wl-Y[stack_size].
5295 The mem file is different for this option as well, since it
5296 makes no sense of talking about DSEG lenght.
5298 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5300 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5301 in certain cases, e.g. when ROM assignment, patch provided
5302 from Albert den Haan.
5304 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6347 A few small changes that speed up the peephole optimizer.
6351 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6353 Try to make the peephole optimizer smarter by maintaining
6354 an association between the assembly source code and the
6355 iCodes that originated them. Put this information to use
6356 with a new peephole rule condition "notVolatile" so that
6357 the rules can be aggressive yet still safe.
6362 * src/mcs51/peeph.def
6364 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6368 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6369 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6370 if the left or right operand symbols have the accuse flag set.
6372 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6374 Changed the type of the result of the ! (NOT) operator to char;
6375 previously it returned the same type as the source. This allows
6376 us to eliminate all the genFloatNot functions (all of its target
6377 implementations were very buggy) since !float can use the same
6380 * src/SDCCicode.c (ast2iCode): ! returns char
6381 * src/mcs51/gen.c (genNot, genNotFloat),
6382 * src/ds390/gen.c (genNot, genNotFloat),
6383 * src/z80/gen.c (genNot, genNotFloat),
6384 * src/pic/gen.c (genNot, genNotFloat),
6385 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6389 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6390 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6391 during interrupts. Ensure WSAVE is located at a shared bank address.
6392 2. Fixed page selection in some places
6393 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6394 the registers name strings.
6395 4. Fixed "signed / unsigned compare" compiler warnings.
6396 5. The PIC port manages its own allocation of the general purpose
6397 registers, but makes no attempt to reuse them. As a result when
6398 compiling it soon runs out of general purpose registers. Some
6399 additional code was added to the files pcode.c and device.c to walk
6400 through the function call tree and rename the registers so that they
6410 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6411 genPlus() & genMinus() when the result is the same as left or right

6417 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6419 Made bitfield a distinct type from bit so that bitfields
6420 convert as per ANSI C and bits retain their traditional
6421 boolean style behaviour. Implemented bitfield support in
6429 * src/ds390/gen.c: bit v bitfield split
6430 * src/z80/gen.c: New support for bitfields
6431 * support/regression/tests/bitfields.c: reenabled z80,
6434 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6436 Rules 246.x, 247.x relate to bitfields, the others speed up
6437 access to xdata mapped I/O devices.
6439 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6441 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6443 Cleaned up genPackBits and genUnpackBits and added two helper
6444 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6445 for literal assignments in genPackBits (thanks to Frieder for
6451 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6453 Fixed bug #748310 (pointer to function type mishandled when the
6454 function name is omitted). Also fixed a SIGSEGV when a function
6455 attribute (reentrant, etc) is used on a non-function or on a
6456 function but misplaced before the parameter list.
6458 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6460 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6483 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6485 Made the constant following the "interrupt" keyword optional. If
6486 omitted, the function will not automatically be given an entry
6487 in the interrupt vector table (similar to #pragma NOIV, but
6488 less syntacticly kludgy). The interrupt number is also now
6489 range checked. Also fixed a bug in the high order bit example

6503 * src/SDCCicode.c (operandOperation): rewritten some ops
6504 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6505 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6507 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6508 be re-activated by defining REDUCE_LITERALS)

6510 unsigned, but are signed by default
6511 * src/SDCCval.c (constVal): rearranged
6512 * src/SDCCval.c (valMod): preliminary fix
6513 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6958 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
6959 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
6960 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
6963 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6965 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6966 the regression tests I'm not brave enough to enable 245.b, 245.c
6967 * doc/sdccman.lyx: added latex preamble for hyperref package.
6968 Using pdflatex this will give you a hyperlinked pdf file with
6969 bookmarks. (prepend '%' before /usepackage if this breaks something)

6981 * src/SDCCglue.c (printIval): fixed bug #739934
6983 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
6985 Applied patch from bug 737905 (renamed yylineo to mylineno):
6992 * src/pic16/pcode.c: Cleaned warnings
6993 * src/pic16/pcodeflow.c: Cleaned warnings
6994 * src/pic16/pcoderegs.c: Cleaned warnings

7007 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7009 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7010 it can be defined with CFLAGS when running configure
7011 * src/SDCCmain.c: fixed compiling + linking with object files
7013 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7015 * configure.in: configure for pic16 port,
7016 added --disable-pic16-port
7017 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7018 * src/SDCCmain.c: linkOptions is changed to set *,
7019 added if/endif conditional macros to remove options help
7020 messages from optionsTable when a port is not configured, added
7021 support for the PIc16 port in the ports table, when executing
7022 the compiler with no port specified on command line, a default
7023 port is selected with the new macro DEFAULT_PORT which is
7024 defined in port.h, in setDefaultOptions() linkOptions is removed
7025 from initialization assignment, since now it is a set,
7026 parseCmdLine uses setParseWithComma for linkOptions, in
7027 linkEdit() linkOptions are accessed with new function indexSet()
7028 which returns the i'th item of a set variable. See SDCCset.c, in
7029 linkEdit() when calling buildCmdLine(), added linkOptions as
7030 last argument. Now users can pass arguments to gplink via the
7031 -Wl option, main() uses pic16glue() to glue up pic16 programs
7032 * src/SDCCpeeph.c: various changes to support pic16

7043 * src/pic16/glue.c: commented out some error producing lines
7044 * src/pic16/main.c: __config directives are commented out to stop
7045 gpasm complaining and test the linkage with gplink, _linkCmd and
7046 _asmCmd changed to be more gplink and gpasm friendly
7047 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7048 produced an error when parsed, peep rule 12 is added to utilize
7049 movff, but it is commented out since the pCode does not support
7050 yet a command with 2 address arguments
7052 2003-05-18 <johan AT balder>
7054 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7055 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7079 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7081 2003-05-11 Borut Razem <borut.razem AT siol.net>
7083 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7084 the path of bin directory, so that PATH is the only env. variable, which has to be set
7085 in case of standard installation.
7086 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8089 * src/SDCCicode.c: fixed array add
8091 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8092 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8093 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8095 2003-01-04 <johan AT balder>
8097 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8099 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8100 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8102 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8103 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8112 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8113 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8115 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8117 * in \sdcc\as\mcs51\ changed these files in order to create an
8118 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8119 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8120 following files to include the previous two files: aslink.dsp,
8121 Makefile.aslink, Makefile.bcc, and Makefile.in.
8123 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8124 .adb instead of .cdb
8126 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8128 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8129 value from option --iram-size.
8131 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8133 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8136 2002-09-18 <wiml AT hhhh.org>
8138 * SDCClrange.h: exposed setFromRange() and setToRange()
8139 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8140 packRegsForAccUse() (bug 542397)
8141 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8142 multiple times and emitting the fetch operations more than once
8143 added aopGetUsesAcc() function to allow binary operators to
8144 fetch their operands in the correct order; made genMinus() emit
8145 compact code for X = LITERAL - Y
8147 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8148 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8149 sprintf() in line 1267.
8151 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8152 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8155 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8156 Changes to aslink (All the changes are marked with 'JCF'):
8158 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8161 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8162 area BSEG. Also moves, if possible, the DATA area down into the internal
8163 ram so more space is available.
8165 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8168 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8169 not bytes. Function summary() which creates a memory usage summary
8170 file with extension .mem. Reports of overlaping stack and small stack
8171 size. If the space for the stack is less than 16 bytes aslink trows a
8174 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8175 the 8051. Option 'y' for memory summary output file.
8177 Changes to sdcc (All the changes are marked with 'JCF'):
8179 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8181 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8182 overlaying area for it (uses RegBankUsed[4]).
8184 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8185 bank zero as used by default. By default aslink locates the stack
8186 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8187 the creation of the .mem file. Delegates the allocation of data area
8188 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8189 the begining of the stack area to aslink.
8191 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8192 glue() in SDCCglue.c creates an area for it.
8194 2002-09-03 Borut Razem <borut.razem AT siol.net>
8195 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8196 sdcc/src/pic/glue.c:
8197 introduced atexit() handler for teporay files removal in case of
8198 errors, assertions, ...
8200 2002-08-29 Borut Razem <borut.razem AT siol.net>
8201 * sdcc/support/cpp2/auto-host_vc_in.h:
8202 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8203 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8204 Maybe there is a similar problem with BORLANDC? It should be checked!
8206 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8207 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8208 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8209 was not executed, and the compiler (cl) launched a warning:
8210 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8212 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8213 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8215 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8216 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8218 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8219 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8220 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8221 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8222 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8223 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8224 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8225 - added Release configuration in VS projects
8226 - review of compiler an linker options
8227 - VC .exe files are generated in bin_vc directory, not to interfere
8228 with binaries generated from other projects (cygwin, mingw, bcc ...)
8230 * sdcc/src/yacc.dsp: added
8232 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8233 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8234 and insert the version number definitions from .version
8236 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8238 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8239 added - genarate auto-host.h using auto-host_vc_in.h as template
8242 removed from CVS, generated automatically
8244 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8245 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8247 2002-08-11 Borut Razem <borut.razem AT siol.net>
8248 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8250 2002-08-10 Borut Razem <borut.razem AT siol.net>
8251 * src/SDCCmain.c (main):
8252 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8253 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8254 The consequence was that some temporary files were not removed.
8257 unification of code in functions tempfilename() and tempfile():
8258 function tempnam() is defined in Visual Studio 6.0 and .NET
8260 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8262 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8263 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8264 - removed compiler command line option /WX: Treats all warnings as errors
8265 - update a list of source files, included into the project
8267 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

8278 added return 0 statements after assert() to make compiler happy
8280 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8281 added newline in the def file to keep MSC compiler satisfied
8283 * sdcc/src/z80/gen.c:
8284 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8285 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8286 - solved MSC error in function aopDump()
8288 * sdcc_vc.h: define PREFIX as "\\sdcc"

8465 * sdcc/src/SDCCloop.c:
8466 Previous fix was not good. basic blocks that have "break" or "return" are
8467 not really partof a loop , but live ranges used in these blocks should
8468 be live thru the entire loop, so set partOfLoop but don't add them to
