1065 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1067 * device/lib/printf_large.c: removed inline assembly for portability and
1068 readability. Use printf_fast if speed or size are more important.
1069 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1070 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1072 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1074 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1075 prevent compiler warning
1077 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1079 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1080 moved to level 0 and declared as static. Also they are explicit
1081 placed in access bank. This was necessery because some times they
1082 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1083 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1084 optimizations. Currently only compare to unsigned char is implemented,
1085 * src/pic16/gen.c: added fReturnIdx array,
1086 * (struct resolvedIfx) is moved to gen.h and made public,
1087 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1088 * (aopForSym): added an optimization to directly store in stack of
1089 the operand of a SEND iCode,
1090 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1091 but as registers instead (AOP_REG) using the fReturnIdx array,
1092 * (pic16_freeAsmop): remove the freed register from the
1093 _G.sregsAlloc field,
1094 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1095 a compare of 'WREG',
1096 * (pic16_popGetTempRegCond): changed function prototype, now
1097 function takes also a bitVector argument v which holds the current
1098 set of registers that are allocated for stack access by aopForSym,
1099 registers allocated in aopForSym for accessing stack symbols are not
1100 any more part of the functions usedRegs field,
1101 * (genCall): some times aopOp is called for a stack variable to be
1102 send, aopForSym might perform the push, if this is true make sure
1103 that genCall doesn't push the variable twice by testing _G.resDirect,
1104 * (genFunction): changed testing for unspecified interrupt number
1105 from 256 to INTNO_UNSPEC,
1106 * modified selection scheme of frame pointer generation. Previously
1107 if function did use local registers a frame pointer was generated,
1108 now a frame pointer is generated only if function has arguments
1109 (that need PLUSW2 register access), or has stack arguments, or the
1110 compiler is not instructed to omit the frame pointer,
1111 * (genEndFunction): before restoring local registers that were saved
1112 in the function preamble, also restore the registers that *might*
1113 have been allocated for stack access,
1114 * (genRet): removed some old comments,
1115 * (genCmp, the active (RN's) version): added a call to the
1116 pic16_genCmp_special function to perform the compare with a more
1117 robust and optimized way,
1118 * (genInline): a feature has been added in inline code generation,
1119 which allows a wildcard variable substitution when writing inline
1120 assembly. Code is incomplete and experimental therefore undocumented,
1121 * (genCast): changed order of aopOp for result and right to allow
1122 aopForSym to directly load the result if possible,
1123 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1124 perform an optimized compare on some selected special occasions,
1125 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1126 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1127 generate an IVT any more,
1128 * src/pic16/main.c (pic16_optionsTable): added command line option
1130 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1131 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1133 * src/pic16/NOTES: Raphael Neider added in list of active developers
1134 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1135 jumptable_end to prevent bug #,
1136 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1137 inCond and outCond fields,
1138 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1139 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1140 turn off register spilling,
1141 * (packRegsForOneUse): synced with other ports' versions although it
1142 is not used currently,
1143 * (pic16_packRegisters): added an optimization while reading
1144 structure bitfields, some registers may be saved (malloc code is
1145 decreased by 80 bytes)
1147 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1149 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1150 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1151 this can be optimized more?
1153 2005-03-10 Raphael Neider <rneider AT web.de>
1155 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1156 genNearPointerGet): (hopefully) fixed access to bitfields via
1157 pointers (p->bitN = x; and x = p->bitN; failed)

1772 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
1774 (setFromConditionArgs): friendly operand parser for peephole rules,
1775 (operandBaseName, operandsNotRelated): new peephole condition
1776 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1777 architecture specific register naming into account, handles n-way
1778 comparisons, and supports quoted literals
1779 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

1789 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1791 Adding support for replacing ljmps with sjmps in jumptables
1792 generated for switch statements. For now you need to set the
1793 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1794 Now 4 algorithms for mcs51 jumptable generation are used:
1795 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1796 addresses loaded pc-relative for up to 112 cases and stack-pushing
1797 target addresses loaded with offset from dptr for up to 256 cases.
1799 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1800 * src/mcs51/main.c: adapted constants for switch table generation
1801 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1824 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1825 to call when a stack overflow occurs,
1826 * (malloc.h): added CVS Id tag,
1827 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1829 * added libc directory. The current version of LibC contains string
1830 functions, ctype functions and macros and some functions of the
1831 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1832 be extensively tested in the future. Standard disclaimer here.
1833 Library is not automatically build yet. But one can build it by
1834 invoking 'make' inside the libc directory.
1835 * added ADC library under libio. Preliminary version yet.
1837 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1844 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1845 * (pic16_storeForReturn): optimized return of 0,
1846 * (genCmp): experimental code for new genCmp which uses PIC18's
1847 special compare&skip instructions. Initial tests fail some times
1848 with variables grater than 1 byte in size, so new code is disabled,
1849 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1851 * (genCast): began a fix to optimize the casting of a bit to another
1852 bit, now assigning a bitfield to another bitfield will fail, sorry,
1853 * src/pic16/main.c: disabled the use of lr-support feature,
1854 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1855 * added some function prototypes, added function _debugf prototype,

1857 bits with offset (case PO_GPR_BIT),
1858 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1860 * (isBankInstruction): modified to return 0 for no banking instruction,
1861 and 1 for banking instruction,
1862 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1863 caused stop processing pCodes after a inline assembly block,
1864 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1865 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1866 registers when it shouldn't,
1867 * src/pic16/ralloc.c (allocReg): add preliminary support for
1868 supporting a limited set of temporary registers,
1870 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1872 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1873 genDataPointerSet): ensure assignments always copy in MSB to LSB
1875 (loadRegFromAop): recognize CLRH optimization,
1876 (genFunction): optimize RECEIVE iCodes in reentrant functions
1878 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1880 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1881 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1883 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
1884 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
1885 contiguous with data

1889 * device/lib/_gptrget.c (_gptrget),
1890 * device/lib/_gptrgetc.c (_gptrgetc),
1891 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1892 instead of sjmp to ret
1893 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1894 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1896 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4875 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4877 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4878 loaded with the linker search paths (-L arguments) and the libraries
4879 to be linked with the current source (-l arguments). Changes
4880 currently will affect only the pic16 port.
4881 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4882 include path the port specific paths and port specific libraries,
4883 * gplink command now contains the $3 argument,
4884 * src/pic16/device.h,
4885 * src/pic16/device.c,: structure PIC_device is made public and
4886 renamed to PIC16_device, the same for variable Pics which is renamed
4887 to Pics16. Updated all references to them.
4888 * src/pic16/glue.c (pic16glue): corrected bug with code
4889 initialization which bypassed the variable initializations block.

4899 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4901 Documenting changes from previous commits.
4902 * configure.in (version 1.56),
4903 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4904 when generating output files to configure the pic16 library,
4905 but now I've commented it out, since gputils aren't installed in the
4906 SF compile farm, so library won't compile
4908 * device/lib/Makefile.in (version 1.56): initially I've added in
4909 target 'all' the prerequestive 'model-pic16' so it compiled the
4910 pic16 library, but now I've commented it out for the same reasons
4912 * added targets 'model-pic16' and 'objects-pic16' to compile the
4914 * added target 'port-specific-objects-pic16' to handle the
4915 generated libraries and copy them into the build/ directory
4916 * added target 'clean-intermediate-pic16' to clean intermediate
4917 files into pic16 directory
4918 * in target 'installdirs' added line to create directory pic16 in
4919 the installation path
4921 * device/include/Makefile.in (version 1.11): in target 'install'
4922 added lines to copy all header files to installation path,
4923 * in target 'installdirs' added line create directory for pic16
4924 headers in the installation path

4939 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4940 option so that it actually works. Made it specific to the z80, since
4941 the gbz80 doesn't have these kinds of I/O ports.
4943 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4945 * device/include/z180.h,

4954 portmode; added deprecation warning for bank= and protmode= forms.
4955 Also, guard against buffer overflow.
4956 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4958 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4960 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4961 changed interrupt vector table generation to only emit declared vectors.
4962 * device/include/Makefile.in: added missing backslash
4963 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4965 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4967 Mainly changes to support compilation of the device libraries
4968 * src/pic16/device.c: stack is allocated via symbol and not
4969 via literal number. The symbol is placed in the corresponding
4970 position of the data ram
4971 * (pic16_dump_section): relocatable and absolute uninitialized
4972 data are now emitted in sorted order to reduce section naming,
4973 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4974 weren't marked as being in the access bank,
4976 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4978 Added portion of GNU PIC Library under the directory
4979 device/include/pic16 and device/lib/pic16. These files
4980 contain the declarations of SFRs for the PIC18Fxx2 devices.
4981 The directory is initialized via configure from toplevel.
4983 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4985 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4986 the spilllocations to be compared correctly
4988 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4990 * src/SDCCast.c (decorateType): fixed bug introduced today
4992 2004-01-12 Borut Razem <borut.razem AT siol.net>
4994 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4997 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4999 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5000 in simpler and even better code
5002 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5004 * src/SDCCicode.c (operandOperation): fixed bug #874819

5008 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5010 * doc/sdccman.lyx: Moved and added some sections, small changes
5011 all over. Telling LaTeX to be less strict with word spacing
5012 to better keep the right margin. Changed some notes about
5013 maintainance of the ports in section 3.2.1 - is it OK like this?
5015 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5017 SDCC source changes:
5018 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5051 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5052 UPPER for immediate operands,
5053 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5055 * src/pic16/peeph.def: all peepholes with movff are commented out,
5056 because there is a problem in the pcode peep optimizer,
5057 * src/pic16/ralloc.c: the register allocator can now reuse local
5058 function symbols for another function. This saves register usage.
5059 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5061 Added file src/pic16/NOTES with information about program writing on
5062 the current port version.

5071 * src/SDCCmain.c : fixed #872250: -l command line defined library
5072 files are scanned before standard library files
5074 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5094 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5097 * src/z80/main.c: added missed needLinkerScript flags (more than
5098 one port structure defined in these file)
5099 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5115 needLinkerScript flag
5117 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5118 * src/pic/glue.c: added variable udata_section_name to
5119 override default uninitialized data segment definition for

5121 * (pic14emitOverlay): modified to emit a commented overlay segment
5122 directive when no overlay data exist
5123 * (picglue): modified to emit uninitialized data segment
5124 according to udata_section_name

5129 arguments via -W option
5130 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5131 object file from '.rel' to '.o' in port->linker structure,
5132 changed size of fptr from 2 to 3 in port structure
5134 2004-01-07 Borut Razem <borut.razem AT siol.net>
5136 * support/scripts/sdcc.nsi: update PATH
5137 * support/scripts/sdcc.ico: craeted
5139 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5142 * doc/Makefile: fix install
5144 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5146 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5148 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5150 include information about variables allocated to the overlay
5153 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5155 * as/mcs51/lkmain.c: Help about -Y option

5165 LEFT_OP (left shift)
5167 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5169 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5170 (default behaviour).
5172 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5174 A python script to validate compiler diagnostic messages. It can be
5175 used to verify that sdcc complains about bad c source code and
5176 gives a good location of the error.
5177 * support/valdiag/Makefile,
5178 * support/valdiag/valdiag.py,
5179 * support/valdiag/tests/*
5181 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5192 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5194 * src/common.h: added ifndef/define/endif macros
5195 around the header file.
5196 Bug reported from Jesus Calvino-Fraga
5198 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5200 * sdcc.spec: updated
5201 * device/include/Makefile.in: don't install CVS directories
5202 * device/lib/Makefile.in: added removal of CVS directories after install
5203 * doc/Makefile: fixed install, added local_icons
5204 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5205 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5206 * src/ds390/gen.c (genRightShift): fixed bug #870788
5207 * src/SDCCast.c (decorateType): fixed bug #870781
5209 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5211 PIC16 port related changes:
5212 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5213 added variable stackPos,
5215 * gen.c: genCall, assignResultValue: added support for
5216 pushing/retrieving function parameters to/from stack,
5217 genFunction,genEndFunction: setup stack frame for the
5219 genAddrOf: will be changed according to bug 863624
5221 * added files genutils.c and genutils.h which contain gen*
5222 debugged and optimised functions extracted from gen.c
5224 * glue.c: added variable 'externs' which holds extern symbols,
5225 pic16emitRegularMap: is modified to properly handle relocatable
5226 symbols under the new scheme,
5227 pic16createInterruptVect: is modified
5228 pic16printPublics: is modified to emit 'global' assembler directives,
5229 added pic16_printExterns to print extern symbols,
5230 pic16glue: initializes stack/frame pointer in the beginning of
5231 the assembly output. Temporary hack, will be corrected later,
5232 because gplink yet does not support stack and SDCC does not
5233 yet support a type of crt0.o object to create the final binary.
5235 * Removed many lines that contain 8051 legacy code.
5236 * The code is finally placed under a 'code' directive.
5237 * Added port specific options.
5239 * _process_pragma: simplified since now we do not need *special*
5240 include file to define SFR registers. But a separate header
5241 will be needed. This will be developed later.
5242 * _pic16_parseOptions: added, parses port specific options:
5243 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5244 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5245 --preplace-udata-with=
5247 * _pic16_setDefaultOptions: modified to initialize section names,
5248 but hack is temporarly out of order since it needs improvement.
5249 * _pic16_genAssemblerPreamble: configuration words are emitted by
5250 their address instead of their name. This part is incomplete and
5251 supports only the 18Fxx2 devices. Other devices will emit an error
5252 during assembly since they do not contain the same set of config
5254 * _pic16_genIVT: is modified,
5256 * pcode.c: added definitions for some hardware registers that are needed
5258 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5259 All PCI entries are updated. Now LFSR is supported.
5260 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5261 * added pic16_newpCodeOpLit2 to support instructions with
5262 two literal arguments
5263 * pic16_pCode2str: corrected code that emits assembler instructions
5264 with two literal operands and those that have an access bit modifier
5265 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5266 this fixes a bug which caused some labels to be lost, when an
5267 assembler directive was added, i.e. banksel,
5268 * pic16_FixRegisterBanking: improved logic that causes the insertion
5270 * InlineFunction: functions that are called once, are not any more
5271 inlined. This can be a port option in the future,
5273 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5275 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5276 hold the corresponding uninitialized symbols,
5277 * pic16_allocProcessorRegister: registers have explicit marked the
5279 * pic16_allocInternalRegister: registers are explicit marked as
5281 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5282 processing list, so bit registers were lost,
5285 * ralloc.h: added field 'accessBank' and original symbol operand
5286 in register definition,
5287 * removed the field isMapped from register definition,
5289 ** Several functions have been removed from various sources:
5290 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5291 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5292 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5293 pic16_assignRelocatableRegisters
5295 ** others have been introduced:
5296 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5297 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5299 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5301 * support/scripts/inc2h.pl: changed definition of BIT_AT
5302 to emit 'sbit at' instead of 'bit at'. This was a request.
5304 PIC16 port related preliminary changes:
5305 * gen.c: prefixed function popRegFromString with
5306 pic16_ and all references to it corrected
5307 * pcode.c: all pic16_pc_* hardware registers prefixed
5308 with underscore (_),
5309 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5310 * ralloc.c: newReg(): when register is REG_SFR then
5311 set address to rIdx,
5312 pic16_allocProcessorRegister(): marks register wasUsed=0
5313 pic16_writeUsedRegs(): added a call to assign processor
5314 registers via pic16_assignFixedRegisters
5316 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5318 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5319 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5320 variables in unused register banks. Also the SSEG is placed
5321 wherever there is enough space for it, and IDATA can be anywhere
5322 in internal RAM. For now compile using -Wl-Y[stack_size].
5323 The mem file is different for this option as well, since it
5324 makes no sense of talking about DSEG lenght.
5326 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5328 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5329 in certain cases, e.g. when ROM assignment, patch provided
5330 from Albert den Haan.
5332 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5343 (geniCodeArray): ditto
5344 * src/SDCCicode.h: made geniCodeCast() static: removed prototype
5345 * src/SDCCsymt.c (computeType): added more support for char;

6339 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6340 If they pop r0/r1 they must be called in the opposite order than aopOp().
6341 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6342 (resp. --stack-auto), prepared for --xstack

6348 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6350 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6351 these ports have their own __sdcc_external_start()
6353 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6355 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6356 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6357 type for bits was changed. It resulted in bit variables becoming
6358 global, which is not permitted in PIC 14 assembly output.
6360 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6362 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6364 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6366 Z80 and MCS51 linkers complaint if a public symbol is defined

6375 A few small changes that speed up the peephole optimizer.
6379 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6381 Try to make the peephole optimizer smarter by maintaining
6382 an association between the assembly source code and the
6383 iCodes that originated them. Put this information to use
6384 with a new peephole rule condition "notVolatile" so that
6385 the rules can be aggressive yet still safe.
6390 * src/mcs51/peeph.def
6392 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6396 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6397 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6398 if the left or right operand symbols have the accuse flag set.
6400 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6402 Changed the type of the result of the ! (NOT) operator to char;
6403 previously it returned the same type as the source. This allows
6404 us to eliminate all the genFloatNot functions (all of its target
6405 implementations were very buggy) since !float can use the same
6408 * src/SDCCicode.c (ast2iCode): ! returns char

6410 * src/ds390/gen.c (genNot, genNotFloat),
6411 * src/z80/gen.c (genNot, genNotFloat),
6412 * src/pic/gen.c (genNot, genNotFloat),
6413 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6417 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6418 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6419 during interrupts. Ensure WSAVE is located at a shared bank address.
6420 2. Fixed page selection in some places
6421 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6422 the registers name strings.
6423 4. Fixed "signed / unsigned compare" compiler warnings.
6424 5. The PIC port manages its own allocation of the general purpose
6425 registers, but makes no attempt to reuse them. As a result when
6426 compiling it soon runs out of general purpose registers. Some
6427 additional code was added to the files pcode.c and device.c to walk
6428 through the function call tree and rename the registers so that they
6438 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6439 genPlus() & genMinus() when the result is the same as left or right

6445 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6447 Made bitfield a distinct type from bit so that bitfields
6448 convert as per ANSI C and bits retain their traditional
6449 boolean style behaviour. Implemented bitfield support in
6457 * src/ds390/gen.c: bit v bitfield split
6458 * src/z80/gen.c: New support for bitfields
6459 * support/regression/tests/bitfields.c: reenabled z80,
6462 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6464 Rules 246.x, 247.x relate to bitfields, the others speed up
6465 access to xdata mapped I/O devices.
6467 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6469 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6471 Cleaned up genPackBits and genUnpackBits and added two helper
6472 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6473 for literal assignments in genPackBits (thanks to Frieder for
6479 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6481 Fixed bug #748310 (pointer to function type mishandled when the
6482 function name is omitted). Also fixed a SIGSEGV when a function
6483 attribute (reentrant, etc) is used on a non-function or on a
6484 function but misplaced before the parameter list.
6486 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6488 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6511 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6513 Made the constant following the "interrupt" keyword optional. If
6514 omitted, the function will not automatically be given an entry
6515 in the interrupt vector table (similar to #pragma NOIV, but
6516 less syntacticly kludgy). The interrupt number is also now
6517 range checked. Also fixed a bug in the high order bit example

6531 * src/SDCCicode.c (operandOperation): rewritten some ops
6532 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6533 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6535 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6536 be re-activated by defining REDUCE_LITERALS)
6537 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6538 unsigned, but are signed by default
6539 * src/SDCCval.c (constVal): rearranged
6540 * src/SDCCval.c (valMod): preliminary fix
6541 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6993 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6994 the regression tests I'm not brave enough to enable 245.b, 245.c
6995 * doc/sdccman.lyx: added latex preamble for hyperref package.
6996 Using pdflatex this will give you a hyperlinked pdf file with
6997 bookmarks. (prepend '%' before /usepackage if this breaks something)

7013 Applied patch from bug 737905 (renamed yylineo to mylineno):
7020 * src/pic16/pcode.c: Cleaned warnings
7021 * src/pic16/pcodeflow.c: Cleaned warnings
7022 * src/pic16/pcoderegs.c: Cleaned warnings

7038 it can be defined with CFLAGS when running configure
7039 * src/SDCCmain.c: fixed compiling + linking with object files
7041 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7044 added --disable-pic16-port
7045 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7046 * src/SDCCmain.c: linkOptions is changed to set *,
7047 added if/endif conditional macros to remove options help
7048 messages from optionsTable when a port is not configured, added
7049 support for the PIc16 port in the ports table, when executing
7050 the compiler with no port specified on command line, a default
7051 port is selected with the new macro DEFAULT_PORT which is
7052 defined in port.h, in setDefaultOptions() linkOptions is removed
7053 from initialization assignment, since now it is a set,
7054 parseCmdLine uses setParseWithComma for linkOptions, in
7055 linkEdit() linkOptions are accessed with new function indexSet()
7056 which returns the i'th item of a set variable. See SDCCset.c, in
7057 linkEdit() when calling buildCmdLine(), added linkOptions as
7058 last argument. Now users can pass arguments to gplink via the
7059 -Wl option, main() uses pic16glue() to glue up pic16 programs
7060 * src/SDCCpeeph.c: various changes to support pic16

7071 * src/pic16/glue.c: commented out some error producing lines
7072 * src/pic16/main.c: __config directives are commented out to stop
7073 gpasm complaining and test the linkage with gplink, _linkCmd and
7074 _asmCmd changed to be more gplink and gpasm friendly
7075 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7076 produced an error when parsed, peep rule 12 is added to utilize
7077 movff, but it is commented out since the pCode does not support
7078 yet a command with 2 address arguments
7080 2003-05-18 <johan AT balder>
7082 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7083 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7109 2003-05-11 Borut Razem <borut.razem AT siol.net>
7111 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7112 the path of bin directory, so that PATH is the only env. variable, which has to be set
7113 in case of standard installation.
7114 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8143 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8145 * in \sdcc\as\mcs51\ changed these files in order to create an
8146 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8147 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8148 following files to include the previous two files: aslink.dsp,
8149 Makefile.aslink, Makefile.bcc, and Makefile.in.
8151 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8152 .adb instead of .cdb
8154 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8156 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8157 value from option --iram-size.
8159 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8161 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8164 2002-09-18 <wiml AT hhhh.org>
8166 * SDCClrange.h: exposed setFromRange() and setToRange()
8167 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8168 packRegsForAccUse() (bug 542397)
8169 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8170 multiple times and emitting the fetch operations more than once
8171 added aopGetUsesAcc() function to allow binary operators to
8172 fetch their operands in the correct order; made genMinus() emit
8173 compact code for X = LITERAL - Y
8175 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8176 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8177 sprintf() in line 1267.
8179 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8180 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8183 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8184 Changes to aslink (All the changes are marked with 'JCF'):
8186 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8189 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8190 area BSEG. Also moves, if possible, the DATA area down into the internal
8191 ram so more space is available.
8193 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8196 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8197 not bytes. Function summary() which creates a memory usage summary
8198 file with extension .mem. Reports of overlaping stack and small stack
8199 size. If the space for the stack is less than 16 bytes aslink trows a
8202 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8203 the 8051. Option 'y' for memory summary output file.
8205 Changes to sdcc (All the changes are marked with 'JCF'):
8207 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8209 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8210 overlaying area for it (uses RegBankUsed[4]).
8212 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8213 bank zero as used by default. By default aslink locates the stack
8214 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8215 the creation of the .mem file. Delegates the allocation of data area
8216 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8217 the begining of the stack area to aslink.
8219 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8220 glue() in SDCCglue.c creates an area for it.
8222 2002-09-03 Borut Razem <borut.razem AT siol.net>
8223 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8224 sdcc/src/pic/glue.c:
8225 introduced atexit() handler for teporay files removal in case of
8226 errors, assertions, ...
8228 2002-08-29 Borut Razem <borut.razem AT siol.net>
8229 * sdcc/support/cpp2/auto-host_vc_in.h:
8230 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8231 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8232 Maybe there is a similar problem with BORLANDC? It should be checked!
8234 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8235 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8236 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8237 was not executed, and the compiler (cl) launched a warning:
8238 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8240 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8241 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8243 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

8252 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8253 - added Release configuration in VS projects
8254 - review of compiler an linker options
8255 - VC .exe files are generated in bin_vc directory, not to interfere
8256 with binaries generated from other projects (cygwin, mingw, bcc ...)
8258 * sdcc/src/yacc.dsp: added
8260 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8261 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8262 and insert the version number definitions from .version
8264 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8266 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8270 removed from CVS, generated automatically
8272 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8273 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8275 2002-08-11 Borut Razem <borut.razem AT siol.net>
8276 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8278 2002-08-10 Borut Razem <borut.razem AT siol.net>
8279 * src/SDCCmain.c (main):
8280 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8281 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8282 The consequence was that some temporary files were not removed.
8285 unification of code in functions tempfilename() and tempfile():
8286 function tempnam() is defined in Visual Studio 6.0 and .NET
8288 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8290 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8291 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8292 - removed compiler command line option /WX: Treats all warnings as errors
8293 - update a list of source files, included into the project
8295 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8296 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8297 changed project type to Generic Project so that can be correcly converted to VS.NET project
8299 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8301 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

8305 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8306 added return 0 statements after assert() to make compiler happy
8308 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8309 added newline in the def file to keep MSC compiler satisfied
8311 * sdcc/src/z80/gen.c:
8312 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8313 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8314 - solved MSC error in function aopDump()
8316 * sdcc_vc.h: define PREFIX as "\\sdcc"
8318 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8370 Initialized the new field char *Processor field to NULL in all ports
8373 Compiler generated registers for interrupt context saving
8374 were not getting allocated.
8376 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8379 Fixed left shift. Will promote the left side of a left shift
8380 if a) left shifting more than size of operand or b) when assigned
8381 to something size > size of left side
8383 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8493 * sdcc/src/SDCCloop.c:
8494 Previous fix was not good. basic blocks that have "break" or "return" are
8495 not really partof a loop , but live ranges used in these blocks should
8496 be live thru the entire loop, so set partOfLoop but don't add them to
8499 2002-02-21 <johan AT FRIJA>

8528 Karl and Johan start ucsim XA support. Most dissassembly working,
8529 about 75% emulation done(plenty of work remaining).
8531 * sim/ucsim/z80.src:
8532 Add Z80 support to ucsim, add test-ucz80 regression test,
8533 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9372 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
9374 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
9376 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
