1071 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1073 * device/lib/printf_large.c: removed inline assembly for portability and
1074 readability. Use printf_fast if speed or size are more important.
1075 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1076 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1078 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1080 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1081 prevent compiler warning
1083 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1085 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1086 moved to level 0 and declared as static. Also they are explicit
1087 placed in access bank. This was necessery because some times they
1088 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1089 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1090 optimizations. Currently only compare to unsigned char is implemented,
1091 * src/pic16/gen.c: added fReturnIdx array,
1092 * (struct resolvedIfx) is moved to gen.h and made public,
1093 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1094 * (aopForSym): added an optimization to directly store in stack of
1095 the operand of a SEND iCode,
1096 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1097 but as registers instead (AOP_REG) using the fReturnIdx array,
1098 * (pic16_freeAsmop): remove the freed register from the
1099 _G.sregsAlloc field,
1100 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1101 a compare of 'WREG',
1102 * (pic16_popGetTempRegCond): changed function prototype, now
1103 function takes also a bitVector argument v which holds the current
1104 set of registers that are allocated for stack access by aopForSym,
1105 registers allocated in aopForSym for accessing stack symbols are not
1106 any more part of the functions usedRegs field,
1107 * (genCall): some times aopOp is called for a stack variable to be
1108 send, aopForSym might perform the push, if this is true make sure
1109 that genCall doesn't push the variable twice by testing _G.resDirect,
1110 * (genFunction): changed testing for unspecified interrupt number
1111 from 256 to INTNO_UNSPEC,
1112 * modified selection scheme of frame pointer generation. Previously
1113 if function did use local registers a frame pointer was generated,
1114 now a frame pointer is generated only if function has arguments
1115 (that need PLUSW2 register access), or has stack arguments, or the
1116 compiler is not instructed to omit the frame pointer,
1117 * (genEndFunction): before restoring local registers that were saved
1118 in the function preamble, also restore the registers that *might*
1119 have been allocated for stack access,
1120 * (genRet): removed some old comments,
1121 * (genCmp, the active (RN's) version): added a call to the
1122 pic16_genCmp_special function to perform the compare with a more
1123 robust and optimized way,
1124 * (genInline): a feature has been added in inline code generation,
1125 which allows a wildcard variable substitution when writing inline
1126 assembly. Code is incomplete and experimental therefore undocumented,
1127 * (genCast): changed order of aopOp for result and right to allow
1128 aopForSym to directly load the result if possible,
1129 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1130 perform an optimized compare on some selected special occasions,
1131 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1132 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1133 generate an IVT any more,
1134 * src/pic16/main.c (pic16_optionsTable): added command line option
1136 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1137 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1139 * src/pic16/NOTES: Raphael Neider added in list of active developers
1140 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1141 jumptable_end to prevent bug #,
1142 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1143 inCond and outCond fields,
1144 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1145 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1146 turn off register spilling,
1147 * (packRegsForOneUse): synced with other ports' versions although it
1148 is not used currently,
1149 * (pic16_packRegisters): added an optimization while reading
1150 structure bitfields, some registers may be saved (malloc code is
1151 decreased by 80 bytes)
1153 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1155 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1156 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1157 this can be optimized more?
1159 2005-03-10 Raphael Neider <rneider AT web.de>
1161 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1162 genNearPointerGet): (hopefully) fixed access to bitfields via
1163 pointers (p->bitN = x; and x = p->bitN; failed)

1780 (setFromConditionArgs): friendly operand parser for peephole rules,
1781 (operandBaseName, operandsNotRelated): new peephole condition
1782 "operandsNotRelated" -- similar to "operandsNotSame", but takes

1795 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1797 Adding support for replacing ljmps with sjmps in jumptables
1798 generated for switch statements. For now you need to set the
1799 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1800 Now 4 algorithms for mcs51 jumptable generation are used:
1801 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1802 addresses loaded pc-relative for up to 112 cases and stack-pushing
1803 target addresses loaded with offset from dptr for up to 256 cases.
1805 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1806 * src/mcs51/main.c: adapted constants for switch table generation
1807 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1830 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1831 to call when a stack overflow occurs,
1832 * (malloc.h): added CVS Id tag,
1833 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1835 * added libc directory. The current version of LibC contains string
1836 functions, ctype functions and macros and some functions of the
1837 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1838 be extensively tested in the future. Standard disclaimer here.
1839 Library is not automatically build yet. But one can build it by
1840 invoking 'make' inside the libc directory.
1841 * added ADC library under libio. Preliminary version yet.
1843 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1850 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1851 * (pic16_storeForReturn): optimized return of 0,
1852 * (genCmp): experimental code for new genCmp which uses PIC18's
1853 special compare&skip instructions. Initial tests fail some times
1854 with variables grater than 1 byte in size, so new code is disabled,
1855 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1857 * (genCast): began a fix to optimize the casting of a bit to another
1858 bit, now assigning a bitfield to another bitfield will fail, sorry,
1859 * src/pic16/main.c: disabled the use of lr-support feature,
1860 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1861 * added some function prototypes, added function _debugf prototype,

1863 bits with offset (case PO_GPR_BIT),
1864 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1866 * (isBankInstruction): modified to return 0 for no banking instruction,
1867 and 1 for banking instruction,
1868 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1869 caused stop processing pCodes after a inline assembly block,
1870 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1871 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1872 registers when it shouldn't,
1873 * src/pic16/ralloc.c (allocReg): add preliminary support for
1874 supporting a limited set of temporary registers,
1876 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1878 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1879 genDataPointerSet): ensure assignments always copy in MSB to LSB
1881 (loadRegFromAop): recognize CLRH optimization,
1882 (genFunction): optimize RECEIVE iCodes in reentrant functions
1884 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1886 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1887 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1889 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1895 * device/lib/_gptrget.c (_gptrget),
1896 * device/lib/_gptrgetc.c (_gptrgetc),
1897 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1898 instead of sjmp to ret
1899 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1900 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1902 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4881 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4883 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4884 loaded with the linker search paths (-L arguments) and the libraries
4885 to be linked with the current source (-l arguments). Changes
4886 currently will affect only the pic16 port.
4887 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4888 include path the port specific paths and port specific libraries,
4889 * gplink command now contains the $3 argument,
4890 * src/pic16/device.h,
4891 * src/pic16/device.c,: structure PIC_device is made public and
4892 renamed to PIC16_device, the same for variable Pics which is renamed
4893 to Pics16. Updated all references to them.
4894 * src/pic16/glue.c (pic16glue): corrected bug with code
4895 initialization which bypassed the variable initializations block.
4897 * device/lib/pic16/Makefile.rules: removed --penable-stack from

4905 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4907 Documenting changes from previous commits.
4908 * configure.in (version 1.56),
4909 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4910 when generating output files to configure the pic16 library,
4911 but now I've commented it out, since gputils aren't installed in the
4912 SF compile farm, so library won't compile
4914 * device/lib/Makefile.in (version 1.56): initially I've added in
4915 target 'all' the prerequestive 'model-pic16' so it compiled the
4916 pic16 library, but now I've commented it out for the same reasons
4918 * added targets 'model-pic16' and 'objects-pic16' to compile the
4920 * added target 'port-specific-objects-pic16' to handle the
4921 generated libraries and copy them into the build/ directory
4922 * added target 'clean-intermediate-pic16' to clean intermediate
4923 files into pic16 directory
4924 * in target 'installdirs' added line to create directory pic16 in
4925 the installation path
4927 * device/include/Makefile.in (version 1.11): in target 'install'
4928 added lines to copy all header files to installation path,
4929 * in target 'installdirs' added line create directory for pic16
4930 headers in the installation path
4932 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4945 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4946 option so that it actually works. Made it specific to the z80, since
4947 the gbz80 doesn't have these kinds of I/O ports.
4949 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4951 * device/include/z180.h,

4958 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
4959 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4960 portmode; added deprecation warning for bank= and protmode= forms.
4961 Also, guard against buffer overflow.
4962 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4964 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4966 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4967 changed interrupt vector table generation to only emit declared vectors.
4968 * device/include/Makefile.in: added missing backslash
4969 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4971 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4973 Mainly changes to support compilation of the device libraries
4974 * src/pic16/device.c: stack is allocated via symbol and not
4975 via literal number. The symbol is placed in the corresponding
4976 position of the data ram
4977 * (pic16_dump_section): relocatable and absolute uninitialized
4978 data are now emitted in sorted order to reduce section naming,
4979 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4980 weren't marked as being in the access bank,
4982 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4984 Added portion of GNU PIC Library under the directory
4985 device/include/pic16 and device/lib/pic16. These files
4986 contain the declarations of SFRs for the PIC18Fxx2 devices.
4987 The directory is initialized via configure from toplevel.
4989 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4991 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4992 the spilllocations to be compared correctly
4994 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4996 * src/SDCCast.c (decorateType): fixed bug introduced today
4998 2004-01-12 Borut Razem <borut.razem AT siol.net>
5000 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5003 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5005 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5006 in simpler and even better code
5008 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5010 * src/SDCCicode.c (operandOperation): fixed bug #874819

5014 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5016 * doc/sdccman.lyx: Moved and added some sections, small changes
5017 all over. Telling LaTeX to be less strict with word spacing
5018 to better keep the right margin. Changed some notes about
5019 maintainance of the ports in section 3.2.1 - is it OK like this?
5021 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5023 SDCC source changes:
5024 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5057 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5058 UPPER for immediate operands,
5059 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5061 * src/pic16/peeph.def: all peepholes with movff are commented out,
5062 because there is a problem in the pcode peep optimizer,
5063 * src/pic16/ralloc.c: the register allocator can now reuse local
5064 function symbols for another function. This saves register usage.
5065 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5067 Added file src/pic16/NOTES with information about program writing on
5068 the current port version.

5077 * src/SDCCmain.c : fixed #872250: -l command line defined library
5078 files are scanned before standard library files
5080 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5096 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
5097 gen51Code): more efficient parameter receive for --model-large
5100 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5103 * src/z80/main.c: added missed needLinkerScript flags (more than
5104 one port structure defined in these file)
5105 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
5108 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

5111 * src/port.h: added flag needLinkerScript in port->linker
5112 structure to inform whether to create a .lnk file or not,
5120 * src/z80/main.c: changed appropriately to configure
5121 needLinkerScript flag
5123 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5124 * src/pic/glue.c: added variable udata_section_name to
5125 override default uninitialized data segment definition for
5126 devices only with SHAREBANK memory (reported from Erik Epetrich)
5127 * (pic14emitOverlay): modified to emit a commented overlay segment
5128 directive when no overlay data exist
5129 * (picglue): modified to emit uninitialized data segment
5130 according to udata_section_name
5131 * src/pic/main.c (_pic14_parseOptions): added command line

5135 arguments via -W option
5136 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5137 object file from '.rel' to '.o' in port->linker structure,
5138 changed size of fptr from 2 to 3 in port structure
5140 2004-01-07 Borut Razem <borut.razem AT siol.net>
5142 * support/scripts/sdcc.nsi: update PATH
5143 * support/scripts/sdcc.ico: craeted
5145 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
5147 * device/include/Makefile.in: fix install
5148 * doc/Makefile: fix install
5150 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5152 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5154 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
5155 how the function variable allocation summary is displayed; also
5156 include information about variables allocated to the overlay
5159 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5161 * as/mcs51/lkmain.c: Help about -Y option

5171 LEFT_OP (left shift)
5173 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5175 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5176 (default behaviour).
5178 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5180 A python script to validate compiler diagnostic messages. It can be
5181 used to verify that sdcc complains about bad c source code and
5182 gives a good location of the error.
5183 * support/valdiag/Makefile,
5184 * support/valdiag/valdiag.py,
5185 * support/valdiag/tests/*
5187 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5189 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5190 * src/SDCCsymt.c (newEnumType),

5198 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5200 * src/common.h: added ifndef/define/endif macros
5201 around the header file.
5202 Bug reported from Jesus Calvino-Fraga
5204 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5206 * sdcc.spec: updated
5207 * device/include/Makefile.in: don't install CVS directories
5208 * device/lib/Makefile.in: added removal of CVS directories after install
5209 * doc/Makefile: fixed install, added local_icons
5210 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5211 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5212 * src/ds390/gen.c (genRightShift): fixed bug #870788
5213 * src/SDCCast.c (decorateType): fixed bug #870781
5215 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5217 PIC16 port related changes:
5218 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5219 added variable stackPos,
5221 * gen.c: genCall, assignResultValue: added support for
5222 pushing/retrieving function parameters to/from stack,
5223 genFunction,genEndFunction: setup stack frame for the
5225 genAddrOf: will be changed according to bug 863624
5227 * added files genutils.c and genutils.h which contain gen*
5228 debugged and optimised functions extracted from gen.c
5230 * glue.c: added variable 'externs' which holds extern symbols,
5231 pic16emitRegularMap: is modified to properly handle relocatable
5232 symbols under the new scheme,
5233 pic16createInterruptVect: is modified
5234 pic16printPublics: is modified to emit 'global' assembler directives,
5235 added pic16_printExterns to print extern symbols,
5236 pic16glue: initializes stack/frame pointer in the beginning of
5237 the assembly output. Temporary hack, will be corrected later,
5238 because gplink yet does not support stack and SDCC does not
5239 yet support a type of crt0.o object to create the final binary.
5241 * Removed many lines that contain 8051 legacy code.
5242 * The code is finally placed under a 'code' directive.
5243 * Added port specific options.
5245 * _process_pragma: simplified since now we do not need *special*
5246 include file to define SFR registers. But a separate header
5247 will be needed. This will be developed later.
5248 * _pic16_parseOptions: added, parses port specific options:
5249 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5250 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5251 --preplace-udata-with=
5253 * _pic16_setDefaultOptions: modified to initialize section names,
5254 but hack is temporarly out of order since it needs improvement.
5255 * _pic16_genAssemblerPreamble: configuration words are emitted by
5256 their address instead of their name. This part is incomplete and
5257 supports only the 18Fxx2 devices. Other devices will emit an error
5258 during assembly since they do not contain the same set of config
5260 * _pic16_genIVT: is modified,
5262 * pcode.c: added definitions for some hardware registers that are needed
5264 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5265 All PCI entries are updated. Now LFSR is supported.
5266 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5267 * added pic16_newpCodeOpLit2 to support instructions with
5268 two literal arguments
5269 * pic16_pCode2str: corrected code that emits assembler instructions
5270 with two literal operands and those that have an access bit modifier
5271 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5272 this fixes a bug which caused some labels to be lost, when an
5273 assembler directive was added, i.e. banksel,
5274 * pic16_FixRegisterBanking: improved logic that causes the insertion
5276 * InlineFunction: functions that are called once, are not any more
5277 inlined. This can be a port option in the future,
5279 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5281 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5282 hold the corresponding uninitialized symbols,
5283 * pic16_allocProcessorRegister: registers have explicit marked the
5285 * pic16_allocInternalRegister: registers are explicit marked as
5287 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5288 processing list, so bit registers were lost,
5291 * ralloc.h: added field 'accessBank' and original symbol operand
5292 in register definition,
5293 * removed the field isMapped from register definition,
5295 ** Several functions have been removed from various sources:
5296 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5297 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5298 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5299 pic16_assignRelocatableRegisters
5301 ** others have been introduced:
5302 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5303 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5305 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5307 * support/scripts/inc2h.pl: changed definition of BIT_AT
5308 to emit 'sbit at' instead of 'bit at'. This was a request.
5310 PIC16 port related preliminary changes:
5311 * gen.c: prefixed function popRegFromString with
5312 pic16_ and all references to it corrected
5313 * pcode.c: all pic16_pc_* hardware registers prefixed
5314 with underscore (_),
5315 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5316 * ralloc.c: newReg(): when register is REG_SFR then
5317 set address to rIdx,
5318 pic16_allocProcessorRegister(): marks register wasUsed=0
5319 pic16_writeUsedRegs(): added a call to assign processor
5320 registers via pic16_assignFixedRegisters
5322 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5324 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5325 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5326 variables in unused register banks. Also the SSEG is placed
5327 wherever there is enough space for it, and IDATA can be anywhere
5328 in internal RAM. For now compile using -Wl-Y[stack_size].
5329 The mem file is different for this option as well, since it
5330 makes no sense of talking about DSEG lenght.
5332 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5334 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5335 in certain cases, e.g. when ROM assignment, patch provided
5336 from Albert den Haan.
5338 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
5340 Many signedness and type propagation fixes:
5341 * src/SDCCicode.c: made geniCodeCast() static
5342 replaced SPEC_ by IS_ (cosmetic)
5343 (operandOperation): fixed div and mod operation
5344 (usualBinaryConversions): added support for promotion of char
5345 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
5346 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
5347 (geniCodeAdd): an array index will stay unsigned, even if promoted

6344 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6345 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6346 If they pop r0/r1 they must be called in the opposite order than aopOp().
6347 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6348 (resp. --stack-auto), prepared for --xstack

6354 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6356 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6357 these ports have their own __sdcc_external_start()
6359 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6361 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6362 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6363 type for bits was changed. It resulted in bit variables becoming
6364 global, which is not permitted in PIC 14 assembly output.
6366 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6368 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6370 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6372 Z80 and MCS51 linkers complaint if a public symbol is defined

6381 A few small changes that speed up the peephole optimizer.
6385 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6387 Try to make the peephole optimizer smarter by maintaining
6388 an association between the assembly source code and the
6389 iCodes that originated them. Put this information to use
6390 with a new peephole rule condition "notVolatile" so that
6391 the rules can be aggressive yet still safe.
6396 * src/mcs51/peeph.def
6398 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6402 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6403 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6404 if the left or right operand symbols have the accuse flag set.
6406 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6408 Changed the type of the result of the ! (NOT) operator to char;
6409 previously it returned the same type as the source. This allows
6410 us to eliminate all the genFloatNot functions (all of its target
6411 implementations were very buggy) since !float can use the same
6414 * src/SDCCicode.c (ast2iCode): ! returns char

6416 * src/ds390/gen.c (genNot, genNotFloat),
6417 * src/z80/gen.c (genNot, genNotFloat),
6418 * src/pic/gen.c (genNot, genNotFloat),
6419 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6423 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6424 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6425 during interrupts. Ensure WSAVE is located at a shared bank address.
6426 2. Fixed page selection in some places
6427 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6428 the registers name strings.
6429 4. Fixed "signed / unsigned compare" compiler warnings.
6430 5. The PIC port manages its own allocation of the general purpose
6431 registers, but makes no attempt to reuse them. As a result when
6432 compiling it soon runs out of general purpose registers. Some
6433 additional code was added to the files pcode.c and device.c to walk
6434 through the function call tree and rename the registers so that they
6444 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6445 genPlus() & genMinus() when the result is the same as left or right

6451 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6453 Made bitfield a distinct type from bit so that bitfields
6454 convert as per ANSI C and bits retain their traditional
6455 boolean style behaviour. Implemented bitfield support in
6463 * src/ds390/gen.c: bit v bitfield split
6464 * src/z80/gen.c: New support for bitfields
6465 * support/regression/tests/bitfields.c: reenabled z80,
6468 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6470 Rules 246.x, 247.x relate to bitfields, the others speed up
6471 access to xdata mapped I/O devices.
6473 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6475 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6477 Cleaned up genPackBits and genUnpackBits and added two helper
6478 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6479 for literal assignments in genPackBits (thanks to Frieder for
6485 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6487 Fixed bug #748310 (pointer to function type mishandled when the
6488 function name is omitted). Also fixed a SIGSEGV when a function
6489 attribute (reentrant, etc) is used on a non-function or on a
6490 function but misplaced before the parameter list.
6492 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6494 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6517 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6519 Made the constant following the "interrupt" keyword optional. If
6520 omitted, the function will not automatically be given an entry
6521 in the interrupt vector table (similar to #pragma NOIV, but
6522 less syntacticly kludgy). The interrupt number is also now
6523 range checked. Also fixed a bug in the high order bit example

6537 * src/SDCCicode.c (operandOperation): rewritten some ops
6538 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6539 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6541 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6542 be re-activated by defining REDUCE_LITERALS)
6543 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6544 unsigned, but are signed by default
6545 * src/SDCCval.c (constVal): rearranged
6546 * src/SDCCval.c (valMod): preliminary fix
6547 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6999 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7000 the regression tests I'm not brave enough to enable 245.b, 245.c
7001 * doc/sdccman.lyx: added latex preamble for hyperref package.
7002 Using pdflatex this will give you a hyperlinked pdf file with
7003 bookmarks. (prepend '%' before /usepackage if this breaks something)

7050 added --disable-pic16-port
7051 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7052 * src/SDCCmain.c: linkOptions is changed to set *,
7053 added if/endif conditional macros to remove options help
7054 messages from optionsTable when a port is not configured, added
7055 support for the PIc16 port in the ports table, when executing
7056 the compiler with no port specified on command line, a default
7057 port is selected with the new macro DEFAULT_PORT which is
7058 defined in port.h, in setDefaultOptions() linkOptions is removed
7059 from initialization assignment, since now it is a set,
7060 parseCmdLine uses setParseWithComma for linkOptions, in
7061 linkEdit() linkOptions are accessed with new function indexSet()
7062 which returns the i'th item of a set variable. See SDCCset.c, in
7063 linkEdit() when calling buildCmdLine(), added linkOptions as
7064 last argument. Now users can pass arguments to gplink via the
7065 -Wl option, main() uses pic16glue() to glue up pic16 programs

7077 * src/pic16/glue.c: commented out some error producing lines
7078 * src/pic16/main.c: __config directives are commented out to stop
7079 gpasm complaining and test the linkage with gplink, _linkCmd and
7080 _asmCmd changed to be more gplink and gpasm friendly
7081 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7082 produced an error when parsed, peep rule 12 is added to utilize
7083 movff, but it is commented out since the pCode does not support
7084 yet a command with 2 address arguments
7086 2003-05-18 <johan AT balder>
7088 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7089 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7115 2003-05-11 Borut Razem <borut.razem AT siol.net>
7117 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7118 the path of bin directory, so that PATH is the only env. variable, which has to be set
7119 in case of standard installation.

8149 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8151 * in \sdcc\as\mcs51\ changed these files in order to create an
8152 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8153 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8154 following files to include the previous two files: aslink.dsp,
8155 Makefile.aslink, Makefile.bcc, and Makefile.in.
8157 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8158 .adb instead of .cdb
8160 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8162 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8163 value from option --iram-size.
8165 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8167 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8170 2002-09-18 <wiml AT hhhh.org>
8172 * SDCClrange.h: exposed setFromRange() and setToRange()
8173 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8174 packRegsForAccUse() (bug 542397)
8175 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8176 multiple times and emitting the fetch operations more than once
8177 added aopGetUsesAcc() function to allow binary operators to
8178 fetch their operands in the correct order; made genMinus() emit
8179 compact code for X = LITERAL - Y
8181 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8182 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8183 sprintf() in line 1267.
8185 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8186 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8189 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8190 Changes to aslink (All the changes are marked with 'JCF'):
8192 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8195 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8196 area BSEG. Also moves, if possible, the DATA area down into the internal
8197 ram so more space is available.
8199 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8202 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8203 not bytes. Function summary() which creates a memory usage summary
8204 file with extension .mem. Reports of overlaping stack and small stack
8205 size. If the space for the stack is less than 16 bytes aslink trows a
8208 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8209 the 8051. Option 'y' for memory summary output file.
8211 Changes to sdcc (All the changes are marked with 'JCF'):
8213 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8215 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8216 overlaying area for it (uses RegBankUsed[4]).
8218 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8219 bank zero as used by default. By default aslink locates the stack
8220 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8221 the creation of the .mem file. Delegates the allocation of data area
8222 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8223 the begining of the stack area to aslink.
8225 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8226 glue() in SDCCglue.c creates an area for it.
8228 2002-09-03 Borut Razem <borut.razem AT siol.net>
8229 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8230 sdcc/src/pic/glue.c:
8231 introduced atexit() handler for teporay files removal in case of
8232 errors, assertions, ...
8234 2002-08-29 Borut Razem <borut.razem AT siol.net>
8235 * sdcc/support/cpp2/auto-host_vc_in.h:
8236 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8237 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8238 Maybe there is a similar problem with BORLANDC? It should be checked!
8240 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8241 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8242 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8243 was not executed, and the compiler (cl) launched a warning:
8244 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8246 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8247 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8249 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

8256 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8257 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8258 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8259 - added Release configuration in VS projects
8260 - review of compiler an linker options
8261 - VC .exe files are generated in bin_vc directory, not to interfere
8262 with binaries generated from other projects (cygwin, mingw, bcc ...)
8264 * sdcc/src/yacc.dsp: added
8266 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8267 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8268 and insert the version number definitions from .version
8270 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8272 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8276 removed from CVS, generated automatically
8278 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8279 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8281 2002-08-11 Borut Razem <borut.razem AT siol.net>
8282 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8284 2002-08-10 Borut Razem <borut.razem AT siol.net>
8285 * src/SDCCmain.c (main):
8286 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8287 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8288 The consequence was that some temporary files were not removed.
8291 unification of code in functions tempfilename() and tempfile():
8292 function tempnam() is defined in Visual Studio 6.0 and .NET
8294 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8296 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8297 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8298 - removed compiler command line option /WX: Treats all warnings as errors
8299 - update a list of source files, included into the project
8301 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8302 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8303 changed project type to Generic Project so that can be correcly converted to VS.NET project
8305 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8307 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

8311 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8312 added return 0 statements after assert() to make compiler happy
8314 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8315 added newline in the def file to keep MSC compiler satisfied
8317 * sdcc/src/z80/gen.c:
8318 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8319 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8320 - solved MSC error in function aopDump()
8322 * sdcc_vc.h: define PREFIX as "\\sdcc"
8324 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8376 Initialized the new field char *Processor field to NULL in all ports
8379 Compiler generated registers for interrupt context saving
8380 were not getting allocated.
8382 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8385 Fixed left shift. Will promote the left side of a left shift
8386 if a) left shifting more than size of operand or b) when assigned
8387 to something size > size of left side
8389 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8497 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8499 * sdcc/src/SDCCloop.c:
8500 Previous fix was not good. basic blocks that have "break" or "return" are
8501 not really partof a loop , but live ranges used in these blocks should
8502 be live thru the entire loop, so set partOfLoop but don't add them to
8505 2002-02-21 <johan AT FRIJA>
8507 * src/SDCCcse.c: fixed bug #514308
8509 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
