1081 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1083 * device/lib/printf_large.c: removed inline assembly for portability and
1084 readability. Use printf_fast if speed or size are more important.
1085 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1086 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1088 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1090 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1091 prevent compiler warning
1093 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1095 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1096 moved to level 0 and declared as static. Also they are explicit
1097 placed in access bank. This was necessery because some times they
1098 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1099 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1100 optimizations. Currently only compare to unsigned char is implemented,
1101 * src/pic16/gen.c: added fReturnIdx array,
1102 * (struct resolvedIfx) is moved to gen.h and made public,
1103 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1104 * (aopForSym): added an optimization to directly store in stack of
1105 the operand of a SEND iCode,
1106 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1107 but as registers instead (AOP_REG) using the fReturnIdx array,
1108 * (pic16_freeAsmop): remove the freed register from the
1109 _G.sregsAlloc field,
1110 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1111 a compare of 'WREG',
1112 * (pic16_popGetTempRegCond): changed function prototype, now
1113 function takes also a bitVector argument v which holds the current
1114 set of registers that are allocated for stack access by aopForSym,
1115 registers allocated in aopForSym for accessing stack symbols are not
1116 any more part of the functions usedRegs field,
1117 * (genCall): some times aopOp is called for a stack variable to be
1118 send, aopForSym might perform the push, if this is true make sure
1119 that genCall doesn't push the variable twice by testing _G.resDirect,
1120 * (genFunction): changed testing for unspecified interrupt number
1121 from 256 to INTNO_UNSPEC,
1122 * modified selection scheme of frame pointer generation. Previously
1123 if function did use local registers a frame pointer was generated,
1124 now a frame pointer is generated only if function has arguments
1125 (that need PLUSW2 register access), or has stack arguments, or the
1126 compiler is not instructed to omit the frame pointer,
1127 * (genEndFunction): before restoring local registers that were saved
1128 in the function preamble, also restore the registers that *might*
1129 have been allocated for stack access,
1130 * (genRet): removed some old comments,
1131 * (genCmp, the active (RN's) version): added a call to the
1132 pic16_genCmp_special function to perform the compare with a more
1133 robust and optimized way,
1134 * (genInline): a feature has been added in inline code generation,
1135 which allows a wildcard variable substitution when writing inline
1136 assembly. Code is incomplete and experimental therefore undocumented,
1137 * (genCast): changed order of aopOp for result and right to allow
1138 aopForSym to directly load the result if possible,
1139 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1140 perform an optimized compare on some selected special occasions,
1141 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1142 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1143 generate an IVT any more,
1144 * src/pic16/main.c (pic16_optionsTable): added command line option
1146 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1147 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1149 * src/pic16/NOTES: Raphael Neider added in list of active developers
1150 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1151 jumptable_end to prevent bug #,
1152 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1153 inCond and outCond fields,
1154 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1155 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1156 turn off register spilling,
1157 * (packRegsForOneUse): synced with other ports' versions although it
1158 is not used currently,
1159 * (pic16_packRegisters): added an optimization while reading
1160 structure bitfields, some registers may be saved (malloc code is
1161 decreased by 80 bytes)
1163 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1165 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1166 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1167 this can be optimized more?
1169 2005-03-10 Raphael Neider <rneider AT web.de>
1171 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1172 genNearPointerGet): (hopefully) fixed access to bitfields via
1173 pointers (p->bitN = x; and x = p->bitN; failed)
1175 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1805 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1807 Adding support for replacing ljmps with sjmps in jumptables
1808 generated for switch statements. For now you need to set the
1809 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1810 Now 4 algorithms for mcs51 jumptable generation are used:
1811 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1812 addresses loaded pc-relative for up to 112 cases and stack-pushing
1813 target addresses loaded with offset from dptr for up to 256 cases.

1840 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1841 to call when a stack overflow occurs,
1842 * (malloc.h): added CVS Id tag,
1843 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1845 * added libc directory. The current version of LibC contains string
1846 functions, ctype functions and macros and some functions of the
1847 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1848 be extensively tested in the future. Standard disclaimer here.
1849 Library is not automatically build yet. But one can build it by
1850 invoking 'make' inside the libc directory.
1851 * added ADC library under libio. Preliminary version yet.
1853 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1860 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1861 * (pic16_storeForReturn): optimized return of 0,
1862 * (genCmp): experimental code for new genCmp which uses PIC18's
1863 special compare&skip instructions. Initial tests fail some times
1864 with variables grater than 1 byte in size, so new code is disabled,
1865 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1867 * (genCast): began a fix to optimize the casting of a bit to another
1868 bit, now assigning a bitfield to another bitfield will fail, sorry,
1869 * src/pic16/main.c: disabled the use of lr-support feature,
1870 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1873 bits with offset (case PO_GPR_BIT),
1874 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1876 * (isBankInstruction): modified to return 0 for no banking instruction,
1877 and 1 for banking instruction,
1878 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1879 caused stop processing pCodes after a inline assembly block,
1880 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1881 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1882 registers when it shouldn't,
1883 * src/pic16/ralloc.c (allocReg): add preliminary support for
1884 supporting a limited set of temporary registers,
1886 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1888 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1889 genDataPointerSet): ensure assignments always copy in MSB to LSB
1891 (loadRegFromAop): recognize CLRH optimization,
1892 (genFunction): optimize RECEIVE iCodes in reentrant functions
1894 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1896 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

1910 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1912 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4868 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY
4869 (genMultOneByte): fixed bug in signed vs unsigned multiplication
4870 * sim/ucsim/hc08.src/inst.cc (inst_clr): added missing effective
4871 address fetch for clr instruction

4873 * src/SDCCdflow.c (computeDataFlow): fixed bug #878209
4875 2004-01-19 Bernhard Held <bernhard AT bernhardheld.de>
4877 * src/SDCCicode.c (geniCodeArray): applied patch from Stas Sergeev
4878 proposed in FR #877103

4891 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4893 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4894 loaded with the linker search paths (-L arguments) and the libraries
4895 to be linked with the current source (-l arguments). Changes
4896 currently will affect only the pic16 port.
4897 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4898 include path the port specific paths and port specific libraries,
4899 * gplink command now contains the $3 argument,
4900 * src/pic16/device.h,
4901 * src/pic16/device.c,: structure PIC_device is made public and
4902 renamed to PIC16_device, the same for variable Pics which is renamed
4903 to Pics16. Updated all references to them.
4904 * src/pic16/glue.c (pic16glue): corrected bug with code
4905 initialization which bypassed the variable initializations block.
4907 * device/lib/pic16/Makefile.rules: removed --penable-stack from

4915 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4917 Documenting changes from previous commits.
4918 * configure.in (version 1.56),
4919 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4920 when generating output files to configure the pic16 library,
4921 but now I've commented it out, since gputils aren't installed in the
4922 SF compile farm, so library won't compile
4924 * device/lib/Makefile.in (version 1.56): initially I've added in
4925 target 'all' the prerequestive 'model-pic16' so it compiled the
4926 pic16 library, but now I've commented it out for the same reasons
4928 * added targets 'model-pic16' and 'objects-pic16' to compile the
4930 * added target 'port-specific-objects-pic16' to handle the
4931 generated libraries and copy them into the build/ directory
4932 * added target 'clean-intermediate-pic16' to clean intermediate
4933 files into pic16 directory
4934 * in target 'installdirs' added line to create directory pic16 in
4935 the installation path
4937 * device/include/Makefile.in (version 1.11): in target 'install'
4938 added lines to copy all header files to installation path,
4939 * in target 'installdirs' added line create directory for pic16
4940 headers in the installation path

4955 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4956 option so that it actually works. Made it specific to the z80, since
4957 the gbz80 doesn't have these kinds of I/O ports.
4959 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4961 * device/include/z180.h,

4974 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4976 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4977 changed interrupt vector table generation to only emit declared vectors.
4978 * device/include/Makefile.in: added missing backslash
4979 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

4983 Mainly changes to support compilation of the device libraries
4984 * src/pic16/device.c: stack is allocated via symbol and not
4985 via literal number. The symbol is placed in the corresponding
4986 position of the data ram
4987 * (pic16_dump_section): relocatable and absolute uninitialized
4988 data are now emitted in sorted order to reduce section naming,
4989 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4990 weren't marked as being in the access bank,
4992 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4994 Added portion of GNU PIC Library under the directory
4995 device/include/pic16 and device/lib/pic16. These files
4996 contain the declarations of SFRs for the PIC18Fxx2 devices.
4997 The directory is initialized via configure from toplevel.
4999 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5001 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5002 the spilllocations to be compared correctly
5004 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5006 * src/SDCCast.c (decorateType): fixed bug introduced today
5008 2004-01-12 Borut Razem <borut.razem AT siol.net>

5026 * doc/sdccman.lyx: Moved and added some sections, small changes
5027 all over. Telling LaTeX to be less strict with word spacing
5028 to better keep the right margin. Changed some notes about
5029 maintainance of the ports in section 3.2.1 - is it OK like this?
5031 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5033 SDCC source changes:
5034 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5067 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5068 UPPER for immediate operands,
5069 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5071 * src/pic16/peeph.def: all peepholes with movff are commented out,
5072 because there is a problem in the pcode peep optimizer,
5073 * src/pic16/ralloc.c: the register allocator can now reuse local
5074 function symbols for another function. This saves register usage.
5075 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5077 Added file src/pic16/NOTES with information about program writing on
5078 the current port version.

5087 * src/SDCCmain.c : fixed #872250: -l command line defined library
5088 files are scanned before standard library files
5090 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5106 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
5107 gen51Code): more efficient parameter receive for --model-large
5110 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5113 * src/z80/main.c: added missed needLinkerScript flags (more than
5114 one port structure defined in these file)
5115 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
5118 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

5131 needLinkerScript flag
5133 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5134 * src/pic/glue.c: added variable udata_section_name to
5135 override default uninitialized data segment definition for
5136 devices only with SHAREBANK memory (reported from Erik Epetrich)
5137 * (pic14emitOverlay): modified to emit a commented overlay segment
5138 directive when no overlay data exist
5139 * (picglue): modified to emit uninitialized data segment
5140 according to udata_section_name
5141 * src/pic/main.c (_pic14_parseOptions): added command line

5145 arguments via -W option
5146 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5147 object file from '.rel' to '.o' in port->linker structure,
5148 changed size of fptr from 2 to 3 in port structure
5150 2004-01-07 Borut Razem <borut.razem AT siol.net>
5152 * support/scripts/sdcc.nsi: update PATH
5153 * support/scripts/sdcc.ico: craeted
5155 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
5157 * device/include/Makefile.in: fix install
5158 * doc/Makefile: fix install
5160 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5162 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5164 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
5165 how the function variable allocation summary is displayed; also
5166 include information about variables allocated to the overlay
5169 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5171 * as/mcs51/lkmain.c: Help about -Y option

5180 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
5181 LEFT_OP (left shift)
5183 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5185 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5186 (default behaviour).
5188 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5190 A python script to validate compiler diagnostic messages. It can be
5191 used to verify that sdcc complains about bad c source code and
5192 gives a good location of the error.
5193 * support/valdiag/Makefile,
5194 * support/valdiag/valdiag.py,
5195 * support/valdiag/tests/*
5197 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5199 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5200 * src/SDCCsymt.c (newEnumType),
5202 * support/Util/SDCCerr.c,
5203 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
5205 * support/regression/tests/enum.c: added test for enum values that

5208 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5210 * src/common.h: added ifndef/define/endif macros
5211 around the header file.
5212 Bug reported from Jesus Calvino-Fraga
5214 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5216 * sdcc.spec: updated
5217 * device/include/Makefile.in: don't install CVS directories
5218 * device/lib/Makefile.in: added removal of CVS directories after install
5219 * doc/Makefile: fixed install, added local_icons
5220 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5221 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5222 * src/ds390/gen.c (genRightShift): fixed bug #870788
5223 * src/SDCCast.c (decorateType): fixed bug #870781
5225 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5227 PIC16 port related changes:
5228 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5229 added variable stackPos,
5231 * gen.c: genCall, assignResultValue: added support for
5232 pushing/retrieving function parameters to/from stack,
5233 genFunction,genEndFunction: setup stack frame for the
5235 genAddrOf: will be changed according to bug 863624
5237 * added files genutils.c and genutils.h which contain gen*
5238 debugged and optimised functions extracted from gen.c
5240 * glue.c: added variable 'externs' which holds extern symbols,
5241 pic16emitRegularMap: is modified to properly handle relocatable
5242 symbols under the new scheme,
5243 pic16createInterruptVect: is modified
5244 pic16printPublics: is modified to emit 'global' assembler directives,
5245 added pic16_printExterns to print extern symbols,
5246 pic16glue: initializes stack/frame pointer in the beginning of
5247 the assembly output. Temporary hack, will be corrected later,
5248 because gplink yet does not support stack and SDCC does not
5249 yet support a type of crt0.o object to create the final binary.
5251 * Removed many lines that contain 8051 legacy code.
5252 * The code is finally placed under a 'code' directive.
5253 * Added port specific options.
5255 * _process_pragma: simplified since now we do not need *special*
5256 include file to define SFR registers. But a separate header
5257 will be needed. This will be developed later.
5258 * _pic16_parseOptions: added, parses port specific options:
5259 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5260 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5261 --preplace-udata-with=
5263 * _pic16_setDefaultOptions: modified to initialize section names,
5264 but hack is temporarly out of order since it needs improvement.
5265 * _pic16_genAssemblerPreamble: configuration words are emitted by
5266 their address instead of their name. This part is incomplete and
5267 supports only the 18Fxx2 devices. Other devices will emit an error
5268 during assembly since they do not contain the same set of config
5270 * _pic16_genIVT: is modified,
5272 * pcode.c: added definitions for some hardware registers that are needed
5274 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5275 All PCI entries are updated. Now LFSR is supported.
5276 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5277 * added pic16_newpCodeOpLit2 to support instructions with
5278 two literal arguments
5279 * pic16_pCode2str: corrected code that emits assembler instructions
5280 with two literal operands and those that have an access bit modifier
5281 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5282 this fixes a bug which caused some labels to be lost, when an
5283 assembler directive was added, i.e. banksel,
5284 * pic16_FixRegisterBanking: improved logic that causes the insertion
5286 * InlineFunction: functions that are called once, are not any more
5287 inlined. This can be a port option in the future,
5289 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5291 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5292 hold the corresponding uninitialized symbols,
5293 * pic16_allocProcessorRegister: registers have explicit marked the
5295 * pic16_allocInternalRegister: registers are explicit marked as
5297 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5298 processing list, so bit registers were lost,
5301 * ralloc.h: added field 'accessBank' and original symbol operand
5302 in register definition,
5303 * removed the field isMapped from register definition,
5305 ** Several functions have been removed from various sources:
5306 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5307 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5308 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5309 pic16_assignRelocatableRegisters
5311 ** others have been introduced:
5312 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5313 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5315 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5317 * support/scripts/inc2h.pl: changed definition of BIT_AT
5318 to emit 'sbit at' instead of 'bit at'. This was a request.
5320 PIC16 port related preliminary changes:
5321 * gen.c: prefixed function popRegFromString with
5322 pic16_ and all references to it corrected
5323 * pcode.c: all pic16_pc_* hardware registers prefixed
5324 with underscore (_),
5325 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5326 * ralloc.c: newReg(): when register is REG_SFR then
5327 set address to rIdx,
5328 pic16_allocProcessorRegister(): marks register wasUsed=0
5329 pic16_writeUsedRegs(): added a call to assign processor
5330 registers via pic16_assignFixedRegisters
5332 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5334 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5335 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5336 variables in unused register banks. Also the SSEG is placed
5337 wherever there is enough space for it, and IDATA can be anywhere
5338 in internal RAM. For now compile using -Wl-Y[stack_size].
5339 The mem file is different for this option as well, since it
5340 makes no sense of talking about DSEG lenght.
5342 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5344 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5345 in certain cases, e.g. when ROM assignment, patch provided
5346 from Albert den Haan.
5348 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
5350 Many signedness and type propagation fixes:

6347 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
6349 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6350 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6351 fetching of the pointer
6352 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6353 copied from genNearPointerSet()
6354 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6355 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6356 If they pop r0/r1 they must be called in the opposite order than aopOp().
6357 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6358 (resp. --stack-auto), prepared for --xstack

6367 these ports have their own __sdcc_external_start()
6369 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6371 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6372 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6373 type for bits was changed. It resulted in bit variables becoming
6374 global, which is not permitted in PIC 14 assembly output.
6376 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6378 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6380 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6382 Z80 and MCS51 linkers complaint if a public symbol is defined

6391 A few small changes that speed up the peephole optimizer.
6395 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6397 Try to make the peephole optimizer smarter by maintaining
6398 an association between the assembly source code and the
6399 iCodes that originated them. Put this information to use
6400 with a new peephole rule condition "notVolatile" so that
6401 the rules can be aggressive yet still safe.
6406 * src/mcs51/peeph.def
6408 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6412 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6413 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6414 if the left or right operand symbols have the accuse flag set.
6416 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6418 Changed the type of the result of the ! (NOT) operator to char;
6419 previously it returned the same type as the source. This allows
6420 us to eliminate all the genFloatNot functions (all of its target
6421 implementations were very buggy) since !float can use the same
6424 * src/SDCCicode.c (ast2iCode): ! returns char
6425 * src/mcs51/gen.c (genNot, genNotFloat),
6426 * src/ds390/gen.c (genNot, genNotFloat),
6427 * src/z80/gen.c (genNot, genNotFloat),
6428 * src/pic/gen.c (genNot, genNotFloat),
6429 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6433 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6434 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6435 during interrupts. Ensure WSAVE is located at a shared bank address.
6436 2. Fixed page selection in some places
6437 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6438 the registers name strings.
6439 4. Fixed "signed / unsigned compare" compiler warnings.
6440 5. The PIC port manages its own allocation of the general purpose
6441 registers, but makes no attempt to reuse them. As a result when
6442 compiling it soon runs out of general purpose registers. Some
6443 additional code was added to the files pcode.c and device.c to walk
6444 through the function call tree and rename the registers so that they
6454 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6455 genPlus() & genMinus() when the result is the same as left or right

6461 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6463 Made bitfield a distinct type from bit so that bitfields
6464 convert as per ANSI C and bits retain their traditional
6465 boolean style behaviour. Implemented bitfield support in
6473 * src/ds390/gen.c: bit v bitfield split
6474 * src/z80/gen.c: New support for bitfields
6475 * support/regression/tests/bitfields.c: reenabled z80,
6478 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6480 Rules 246.x, 247.x relate to bitfields, the others speed up
6481 access to xdata mapped I/O devices.
6483 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6485 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6487 Cleaned up genPackBits and genUnpackBits and added two helper
6488 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6489 for literal assignments in genPackBits (thanks to Frieder for
6495 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6497 Fixed bug #748310 (pointer to function type mishandled when the
6498 function name is omitted). Also fixed a SIGSEGV when a function
6499 attribute (reentrant, etc) is used on a non-function or on a
6500 function but misplaced before the parameter list.
6502 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6504 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6505 * support/Util/SDCCerr.h,

6527 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6529 Made the constant following the "interrupt" keyword optional. If
6530 omitted, the function will not automatically be given an entry
6531 in the interrupt vector table (similar to #pragma NOIV, but
6532 less syntacticly kludgy). The interrupt number is also now
6533 range checked. Also fixed a bug in the high order bit example

6547 * src/SDCCicode.c (operandOperation): rewritten some ops
6548 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6549 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6551 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6552 be re-activated by defining REDUCE_LITERALS)
6553 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6554 unsigned, but are signed by default
6555 * src/SDCCval.c (constVal): rearranged
6556 * src/SDCCval.c (valMod): preliminary fix
6557 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7009 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7010 the regression tests I'm not brave enough to enable 245.b, 245.c
7011 * doc/sdccman.lyx: added latex preamble for hyperref package.
7012 Using pdflatex this will give you a hyperlinked pdf file with
7013 bookmarks. (prepend '%' before /usepackage if this breaks something)

7062 * src/SDCCmain.c: linkOptions is changed to set *,
7063 added if/endif conditional macros to remove options help
7064 messages from optionsTable when a port is not configured, added
7065 support for the PIc16 port in the ports table, when executing
7066 the compiler with no port specified on command line, a default
7067 port is selected with the new macro DEFAULT_PORT which is
7068 defined in port.h, in setDefaultOptions() linkOptions is removed
7069 from initialization assignment, since now it is a set,
7070 parseCmdLine uses setParseWithComma for linkOptions, in
7071 linkEdit() linkOptions are accessed with new function indexSet()
7072 which returns the i'th item of a set variable. See SDCCset.c, in
7073 linkEdit() when calling buildCmdLine(), added linkOptions as
7074 last argument. Now users can pass arguments to gplink via the
7075 -Wl option, main() uses pic16glue() to glue up pic16 programs

7087 * src/pic16/glue.c: commented out some error producing lines
7088 * src/pic16/main.c: __config directives are commented out to stop
7089 gpasm complaining and test the linkage with gplink, _linkCmd and
7090 _asmCmd changed to be more gplink and gpasm friendly
7091 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7092 produced an error when parsed, peep rule 12 is added to utilize
7093 movff, but it is commented out since the pCode does not support
7094 yet a command with 2 address arguments
7096 2003-05-18 <johan AT balder>
7098 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7099 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7125 2003-05-11 Borut Razem <borut.razem AT siol.net>
7127 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7128 the path of bin directory, so that PATH is the only env. variable, which has to be set
7129 in case of standard installation.

8159 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8161 * in \sdcc\as\mcs51\ changed these files in order to create an
8162 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8163 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8164 following files to include the previous two files: aslink.dsp,
8165 Makefile.aslink, Makefile.bcc, and Makefile.in.
8167 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8168 .adb instead of .cdb
8170 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8172 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8173 value from option --iram-size.
8175 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8177 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8180 2002-09-18 <wiml AT hhhh.org>
8182 * SDCClrange.h: exposed setFromRange() and setToRange()
8183 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8184 packRegsForAccUse() (bug 542397)
8185 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8186 multiple times and emitting the fetch operations more than once
8187 added aopGetUsesAcc() function to allow binary operators to
8188 fetch their operands in the correct order; made genMinus() emit
8189 compact code for X = LITERAL - Y
8191 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8192 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8193 sprintf() in line 1267.
8195 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8196 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8199 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8200 Changes to aslink (All the changes are marked with 'JCF'):
8202 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8205 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8206 area BSEG. Also moves, if possible, the DATA area down into the internal
8207 ram so more space is available.
8209 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8212 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8213 not bytes. Function summary() which creates a memory usage summary
8214 file with extension .mem. Reports of overlaping stack and small stack
8215 size. If the space for the stack is less than 16 bytes aslink trows a
8218 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8219 the 8051. Option 'y' for memory summary output file.
8221 Changes to sdcc (All the changes are marked with 'JCF'):
8223 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8225 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8226 overlaying area for it (uses RegBankUsed[4]).
8228 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8229 bank zero as used by default. By default aslink locates the stack
8230 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8231 the creation of the .mem file. Delegates the allocation of data area
8232 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8233 the begining of the stack area to aslink.
8235 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8236 glue() in SDCCglue.c creates an area for it.
8238 2002-09-03 Borut Razem <borut.razem AT siol.net>
8239 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8240 sdcc/src/pic/glue.c:
8241 introduced atexit() handler for teporay files removal in case of
8242 errors, assertions, ...
8244 2002-08-29 Borut Razem <borut.razem AT siol.net>
8245 * sdcc/support/cpp2/auto-host_vc_in.h:
8246 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8247 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8248 Maybe there is a similar problem with BORLANDC? It should be checked!
8250 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8251 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8252 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8253 was not executed, and the compiler (cl) launched a warning:
8254 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8256 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8257 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8259 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

8264 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8265 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8266 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8267 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8268 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8269 - added Release configuration in VS projects
8270 - review of compiler an linker options
8271 - VC .exe files are generated in bin_vc directory, not to interfere
8272 with binaries generated from other projects (cygwin, mingw, bcc ...)
8274 * sdcc/src/yacc.dsp: added
8276 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8277 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8278 and insert the version number definitions from .version
8280 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8282 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8291 2002-08-11 Borut Razem <borut.razem AT siol.net>
8292 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8294 2002-08-10 Borut Razem <borut.razem AT siol.net>
8295 * src/SDCCmain.c (main):
8296 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8297 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8298 The consequence was that some temporary files were not removed.
8301 unification of code in functions tempfilename() and tempfile():
8302 function tempnam() is defined in Visual Studio 6.0 and .NET
8304 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8306 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8307 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8308 - removed compiler command line option /WX: Treats all warnings as errors
8309 - update a list of source files, included into the project

8321 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8322 added return 0 statements after assert() to make compiler happy
8324 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8325 added newline in the def file to keep MSC compiler satisfied
8327 * sdcc/src/z80/gen.c:
8328 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8329 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8330 - solved MSC error in function aopDump()
8332 * sdcc_vc.h: define PREFIX as "\\sdcc"
8334 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8386 Initialized the new field char *Processor field to NULL in all ports
8389 Compiler generated registers for interrupt context saving
8390 were not getting allocated.
8392 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8395 Fixed left shift. Will promote the left side of a left shift
8396 if a) left shifting more than size of operand or b) when assigned
8397 to something size > size of left side
8399 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8509 * sdcc/src/SDCCloop.c:
8510 Previous fix was not good. basic blocks that have "break" or "return" are
8511 not really partof a loop , but live ranges used in these blocks should
8512 be live thru the entire loop, so set partOfLoop but don't add them to
8515 2002-02-21 <johan AT FRIJA>
