883 where not placed in the same memory bank,
884 * device/lib/pic16/libsdcc/char/: various modifications to improve
886 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many

895 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
896 if condition == CARRY)
897 * (genCmp): adapted to new genSkipc semantics
898 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
899 on rIfx (genCmp was broken)
901 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
903 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
904 * src/z80/main.c (_keywords[]),
905 * src/SDCCglobal.h (struct options),
907 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
908 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
909 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
910 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
911 always available in leading double underscore form. The C99 support is
912 mostly missing, but it's a start.
913 * support/regression/tests/bug-227710.c: fixed nonconforming use of
914 reserved identifier "__data".
916 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

962 2005-03-20 Borut Razem <borut.razem AT siol.net>
964 * support/scripts/inc2h.pl: WIN32 port
966 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
968 * device/lib/makefile.in: added abs.c and labs.c
970 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
972 * device/include/stdint.h: added
973 * device/lib/abs.c: added

990 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
992 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
994 * device/lib/printf_large.c: removed inline assembly for portability and
995 readability. Use printf_fast if speed or size are more important.
996 * src/pic16/gen.c: removed conditions around use of DEBUGpc
997 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
999 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1001 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1002 prevent compiler warning
1004 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1006 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1007 moved to level 0 and declared as static. Also they are explicit
1008 placed in access bank. This was necessery because some times they
1009 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1010 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1011 optimizations. Currently only compare to unsigned char is implemented,
1012 * src/pic16/gen.c: added fReturnIdx array,
1013 * (struct resolvedIfx) is moved to gen.h and made public,
1014 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1015 * (aopForSym): added an optimization to directly store in stack of
1016 the operand of a SEND iCode,
1017 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1018 but as registers instead (AOP_REG) using the fReturnIdx array,
1019 * (pic16_freeAsmop): remove the freed register from the
1020 _G.sregsAlloc field,
1021 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1022 a compare of 'WREG',
1023 * (pic16_popGetTempRegCond): changed function prototype, now
1024 function takes also a bitVector argument v which holds the current
1025 set of registers that are allocated for stack access by aopForSym,
1026 registers allocated in aopForSym for accessing stack symbols are not
1027 any more part of the functions usedRegs field,
1028 * (genCall): some times aopOp is called for a stack variable to be
1029 send, aopForSym might perform the push, if this is true make sure
1030 that genCall doesn't push the variable twice by testing _G.resDirect,
1031 * (genFunction): changed testing for unspecified interrupt number
1032 from 256 to INTNO_UNSPEC,
1033 * modified selection scheme of frame pointer generation. Previously
1034 if function did use local registers a frame pointer was generated,
1035 now a frame pointer is generated only if function has arguments
1036 (that need PLUSW2 register access), or has stack arguments, or the
1037 compiler is not instructed to omit the frame pointer,
1038 * (genEndFunction): before restoring local registers that were saved
1039 in the function preamble, also restore the registers that *might*
1040 have been allocated for stack access,
1041 * (genRet): removed some old comments,
1042 * (genCmp, the active (RN's) version): added a call to the
1043 pic16_genCmp_special function to perform the compare with a more
1044 robust and optimized way,
1045 * (genInline): a feature has been added in inline code generation,
1046 which allows a wildcard variable substitution when writing inline
1047 assembly. Code is incomplete and experimental therefore undocumented,
1048 * (genCast): changed order of aopOp for result and right to allow
1049 aopForSym to directly load the result if possible,
1050 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1051 perform an optimized compare on some selected special occasions,
1052 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1053 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1054 generate an IVT any more,
1055 * src/pic16/main.c (pic16_optionsTable): added command line option
1057 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1058 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1060 * src/pic16/NOTES: Raphael Neider added in list of active developers
1061 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1062 jumptable_end to prevent bug #,
1063 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1064 inCond and outCond fields,
1065 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1066 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1067 turn off register spilling,
1068 * (packRegsForOneUse): synced with other ports' versions although it
1069 is not used currently,
1070 * (pic16_packRegisters): added an optimization while reading
1071 structure bitfields, some registers may be saved (malloc code is
1072 decreased by 80 bytes)
1074 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1076 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1077 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1078 this can be optimized more?
1080 2005-03-10 Raphael Neider <rneider AT web.de>
1082 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1083 genNearPointerGet): (hopefully) fixed access to bitfields via
1084 pointers (p->bitN = x; and x = p->bitN; failed)
1086 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1273 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1274 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1275 this might fix SIGSEGVs on MinGW...
1276 * src/SDCCopt.c (killDeadCode): restored original behaviour
1277 (volatile operands might get thrown away though)
1279 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1719 generated for switch statements. For now you need to set the
1720 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1721 Now 4 algorithms for mcs51 jumptable generation are used:
1722 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1723 addresses loaded pc-relative for up to 112 cases and stack-pushing
1724 target addresses loaded with offset from dptr for up to 256 cases.

1750 Large cummulative patch for pic16 port.
1751 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1752 to call when a stack overflow occurs,
1753 * (malloc.h): added CVS Id tag,
1754 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1756 * added libc directory. The current version of LibC contains string
1757 functions, ctype functions and macros and some functions of the
1758 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1759 be extensively tested in the future. Standard disclaimer here.

4802 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4804 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4805 loaded with the linker search paths (-L arguments) and the libraries
4806 to be linked with the current source (-l arguments). Changes
4807 currently will affect only the pic16 port.
4808 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4809 include path the port specific paths and port specific libraries,
4810 * gplink command now contains the $3 argument,
4811 * src/pic16/device.h,
4812 * src/pic16/device.c,: structure PIC_device is made public and
4813 renamed to PIC16_device, the same for variable Pics which is renamed

4828 Documenting changes from previous commits.
4829 * configure.in (version 1.56),
4830 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4831 when generating output files to configure the pic16 library,
4832 but now I've commented it out, since gputils aren't installed in the
4833 SF compile farm, so library won't compile
4835 * device/lib/Makefile.in (version 1.56): initially I've added in
4836 target 'all' the prerequestive 'model-pic16' so it compiled the
4837 pic16 library, but now I've commented it out for the same reasons
4839 * added targets 'model-pic16' and 'objects-pic16' to compile the
4841 * added target 'port-specific-objects-pic16' to handle the
4842 generated libraries and copy them into the build/ directory
4843 * added target 'clean-intermediate-pic16' to clean intermediate
4844 files into pic16 directory
4845 * in target 'installdirs' added line to create directory pic16 in
4846 the installation path
4848 * device/include/Makefile.in (version 1.11): in target 'install'
4849 added lines to copy all header files to installation path,
4850 * in target 'installdirs' added line create directory for pic16
4851 headers in the installation path

4866 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4867 option so that it actually works. Made it specific to the z80, since
4868 the gbz80 doesn't have these kinds of I/O ports.

4896 via literal number. The symbol is placed in the corresponding
4897 position of the data ram
4898 * (pic16_dump_section): relocatable and absolute uninitialized
4899 data are now emitted in sorted order to reduce section naming,
4900 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4901 weren't marked as being in the access bank,
4903 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4905 Added portion of GNU PIC Library under the directory
4906 device/include/pic16 and device/lib/pic16. These files
4907 contain the declarations of SFRs for the PIC18Fxx2 devices.

4937 * doc/sdccman.lyx: Moved and added some sections, small changes
4938 all over. Telling LaTeX to be less strict with word spacing
4939 to better keep the right margin. Changed some notes about
4940 maintainance of the ports in section 3.2.1 - is it OK like this?
4942 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4979 UPPER for immediate operands,
4980 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4982 * src/pic16/peeph.def: all peepholes with movff are commented out,
4983 because there is a problem in the pcode peep optimizer,
4984 * src/pic16/ralloc.c: the register allocator can now reuse local

4986 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4988 Added file src/pic16/NOTES with information about program writing on
4989 the current port version.

5018 gen51Code): more efficient parameter receive for --model-large
5021 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5024 * src/z80/main.c: added missed needLinkerScript flags (more than
5025 one port structure defined in these file)
5026 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5041 * src/z80/main.c: changed appropriately to configure
5042 needLinkerScript flag
5044 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5045 * src/pic/glue.c: added variable udata_section_name to
5046 override default uninitialized data segment definition for

5048 * (pic14emitOverlay): modified to emit a commented overlay segment
5049 directive when no overlay data exist
5050 * (picglue): modified to emit uninitialized data segment
5051 according to udata_section_name

5061 2004-01-07 Borut Razem <borut.razem AT siol.net>
5063 * support/scripts/sdcc.nsi: update PATH
5064 * support/scripts/sdcc.ico: craeted

5071 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5073 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5075 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5077 include information about variables allocated to the overlay
5080 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5082 * as/mcs51/lkmain.c: Help about -Y option

5094 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5096 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5097 (default behaviour).
5099 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5101 A python script to validate compiler diagnostic messages. It can be
5102 used to verify that sdcc complains about bad c source code and
5103 gives a good location of the error.
5104 * support/valdiag/Makefile,
5105 * support/valdiag/valdiag.py,
5106 * support/valdiag/tests/*
5108 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5110 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5111 * src/SDCCsymt.c (newEnumType),

5121 * src/common.h: added ifndef/define/endif macros
5122 around the header file.
5123 Bug reported from Jesus Calvino-Fraga
5125 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5127 * sdcc.spec: updated
5128 * device/include/Makefile.in: don't install CVS directories
5129 * device/lib/Makefile.in: added removal of CVS directories after install
5130 * doc/Makefile: fixed install, added local_icons
5131 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5132 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5133 * src/ds390/gen.c (genRightShift): fixed bug #870788
5134 * src/SDCCast.c (decorateType): fixed bug #870781
5136 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5138 PIC16 port related changes:
5139 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5140 added variable stackPos,
5142 * gen.c: genCall, assignResultValue: added support for
5143 pushing/retrieving function parameters to/from stack,
5144 genFunction,genEndFunction: setup stack frame for the
5146 genAddrOf: will be changed according to bug 863624
5148 * added files genutils.c and genutils.h which contain gen*
5149 debugged and optimised functions extracted from gen.c
5151 * glue.c: added variable 'externs' which holds extern symbols,
5152 pic16emitRegularMap: is modified to properly handle relocatable
5153 symbols under the new scheme,
5154 pic16createInterruptVect: is modified
5155 pic16printPublics: is modified to emit 'global' assembler directives,
5156 added pic16_printExterns to print extern symbols,
5157 pic16glue: initializes stack/frame pointer in the beginning of
5158 the assembly output. Temporary hack, will be corrected later,
5159 because gplink yet does not support stack and SDCC does not
5160 yet support a type of crt0.o object to create the final binary.
5162 * Removed many lines that contain 8051 legacy code.
5163 * The code is finally placed under a 'code' directive.
5164 * Added port specific options.
5166 * _process_pragma: simplified since now we do not need *special*
5167 include file to define SFR registers. But a separate header
5168 will be needed. This will be developed later.
5169 * _pic16_parseOptions: added, parses port specific options:
5170 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5171 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5172 --preplace-udata-with=
5174 * _pic16_setDefaultOptions: modified to initialize section names,
5175 but hack is temporarly out of order since it needs improvement.
5176 * _pic16_genAssemblerPreamble: configuration words are emitted by
5177 their address instead of their name. This part is incomplete and
5178 supports only the 18Fxx2 devices. Other devices will emit an error
5179 during assembly since they do not contain the same set of config
5181 * _pic16_genIVT: is modified,
5183 * pcode.c: added definitions for some hardware registers that are needed
5185 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5186 All PCI entries are updated. Now LFSR is supported.
5187 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5188 * added pic16_newpCodeOpLit2 to support instructions with
5189 two literal arguments
5190 * pic16_pCode2str: corrected code that emits assembler instructions
5191 with two literal operands and those that have an access bit modifier
5192 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5193 this fixes a bug which caused some labels to be lost, when an
5194 assembler directive was added, i.e. banksel,
5195 * pic16_FixRegisterBanking: improved logic that causes the insertion
5197 * InlineFunction: functions that are called once, are not any more
5198 inlined. This can be a port option in the future,
5200 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5202 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5203 hold the corresponding uninitialized symbols,
5204 * pic16_allocProcessorRegister: registers have explicit marked the
5206 * pic16_allocInternalRegister: registers are explicit marked as
5208 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5209 processing list, so bit registers were lost,
5212 * ralloc.h: added field 'accessBank' and original symbol operand
5213 in register definition,
5214 * removed the field isMapped from register definition,
5216 ** Several functions have been removed from various sources:
5217 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5218 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5219 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5220 pic16_assignRelocatableRegisters
5222 ** others have been introduced:
5223 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5224 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5226 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5228 * support/scripts/inc2h.pl: changed definition of BIT_AT
5229 to emit 'sbit at' instead of 'bit at'. This was a request.
5231 PIC16 port related preliminary changes:
5232 * gen.c: prefixed function popRegFromString with
5233 pic16_ and all references to it corrected
5234 * pcode.c: all pic16_pc_* hardware registers prefixed
5235 with underscore (_),
5236 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5237 * ralloc.c: newReg(): when register is REG_SFR then
5238 set address to rIdx,
5239 pic16_allocProcessorRegister(): marks register wasUsed=0
5240 pic16_writeUsedRegs(): added a call to assign processor
5241 registers via pic16_assignFixedRegisters
5243 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5245 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5246 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5247 variables in unused register banks. Also the SSEG is placed
5248 wherever there is enough space for it, and IDATA can be anywhere
5249 in internal RAM. For now compile using -Wl-Y[stack_size].
5250 The mem file is different for this option as well, since it
5251 makes no sense of talking about DSEG lenght.
5253 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5255 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5256 in certain cases, e.g. when ROM assignment, patch provided
5257 from Albert den Haan.
5259 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6264 copied from genNearPointerSet()
6265 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6266 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6282 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6283 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6284 type for bits was changed. It resulted in bit variables becoming
6285 global, which is not permitted in PIC 14 assembly output.

6302 A few small changes that speed up the peephole optimizer.
6306 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6308 Try to make the peephole optimizer smarter by maintaining
6309 an association between the assembly source code and the
6310 iCodes that originated them. Put this information to use
6311 with a new peephole rule condition "notVolatile" so that
6312 the rules can be aggressive yet still safe.
6317 * src/mcs51/peeph.def
6319 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6323 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6324 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6325 if the left or right operand symbols have the accuse flag set.
6327 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6329 Changed the type of the result of the ! (NOT) operator to char;
6330 previously it returned the same type as the source. This allows
6331 us to eliminate all the genFloatNot functions (all of its target
6332 implementations were very buggy) since !float can use the same
6335 * src/SDCCicode.c (ast2iCode): ! returns char

6344 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6345 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6346 during interrupts. Ensure WSAVE is located at a shared bank address.
6347 2. Fixed page selection in some places
6348 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6349 the registers name strings.
6350 4. Fixed "signed / unsigned compare" compiler warnings.
6351 5. The PIC port manages its own allocation of the general purpose
6352 registers, but makes no attempt to reuse them. As a result when
6353 compiling it soon runs out of general purpose registers. Some
6354 additional code was added to the files pcode.c and device.c to walk

6441 omitted, the function will not automatically be given an entry
6442 in the interrupt vector table (similar to #pragma NOIV, but
6443 less syntacticly kludgy). The interrupt number is also now
6444 range checked. Also fixed a bug in the high order bit example

6947 * src/pic16/pcode.c: Cleaned warnings
6948 * src/pic16/pcodeflow.c: Cleaned warnings
6949 * src/pic16/pcoderegs.c: Cleaned warnings
6951 2003-05-19 Scott Dattalo <scott AT dattalo.com>
6953 * src/pic16/pcode.c: Cleaned warnings
6954 * src/pic16/pcodepeep.c: Cleaned warnings
6955 * src/pic16/ralloc.c: Cleaned warnings

6959 * doc/sdccman.lyx: fixed bug 739745
6960 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
6962 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6964 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6965 it can be defined with CFLAGS when running configure
6966 * src/SDCCmain.c: fixed compiling + linking with object files
6968 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6970 * configure.in: configure for pic16 port,
6971 added --disable-pic16-port
6972 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6973 * src/SDCCmain.c: linkOptions is changed to set *,
6974 added if/endif conditional macros to remove options help
6975 messages from optionsTable when a port is not configured, added
6976 support for the PIc16 port in the ports table, when executing
6977 the compiler with no port specified on command line, a default
6978 port is selected with the new macro DEFAULT_PORT which is
6979 defined in port.h, in setDefaultOptions() linkOptions is removed
6980 from initialization assignment, since now it is a set,
6981 parseCmdLine uses setParseWithComma for linkOptions, in
6982 linkEdit() linkOptions are accessed with new function indexSet()
6983 which returns the i'th item of a set variable. See SDCCset.c, in
6984 linkEdit() when calling buildCmdLine(), added linkOptions as
6985 last argument. Now users can pass arguments to gplink via the
6986 -Wl option, main() uses pic16glue() to glue up pic16 programs
6987 * src/SDCCpeeph.c: various changes to support pic16
6988 * src/SDCCset.c: added function void *indexSet(set *, int) to
6989 return the i'th item of the set

6991 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
6992 * src/clean.mk: added pic16 in CLEANALLPORTS variable
6993 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
6994 added macro DEFAULT_PORT
6995 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
6996 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6998 * src/pic16/glue.c: commented out some error producing lines
6999 * src/pic16/main.c: __config directives are commented out to stop
7000 gpasm complaining and test the linkage with gplink, _linkCmd and
7001 _asmCmd changed to be more gplink and gpasm friendly
7002 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7003 produced an error when parsed, peep rule 12 is added to utilize
7004 movff, but it is commented out since the pCode does not support
7005 yet a command with 2 address arguments
7007 2003-05-18 <johan AT balder>
7009 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7010 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7034 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7036 2003-05-11 Borut Razem <borut.razem AT siol.net>
7038 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7039 the path of bin directory, so that PATH is the only env. variable, which has to be set
7040 in case of standard installation.

8044 * src/SDCCicode.c: fixed array add
8046 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8047 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8048 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8050 2003-01-04 <johan AT balder>
8052 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8054 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8055 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8057 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8067 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8068 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8070 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8072 * in \sdcc\as\mcs51\ changed these files in order to create an
8073 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8074 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8075 following files to include the previous two files: aslink.dsp,
8076 Makefile.aslink, Makefile.bcc, and Makefile.in.
8078 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8079 .adb instead of .cdb
8081 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8083 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8084 value from option --iram-size.
8086 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8088 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8091 2002-09-18 <wiml AT hhhh.org>
8093 * SDCClrange.h: exposed setFromRange() and setToRange()
8094 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8095 packRegsForAccUse() (bug 542397)
8096 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8097 multiple times and emitting the fetch operations more than once
8098 added aopGetUsesAcc() function to allow binary operators to
8099 fetch their operands in the correct order; made genMinus() emit
8100 compact code for X = LITERAL - Y
8102 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8103 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8104 sprintf() in line 1267.
8106 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8107 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8110 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8111 Changes to aslink (All the changes are marked with 'JCF'):
8113 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8116 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8117 area BSEG. Also moves, if possible, the DATA area down into the internal
8118 ram so more space is available.
8120 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8123 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8124 not bytes. Function summary() which creates a memory usage summary
8125 file with extension .mem. Reports of overlaping stack and small stack
8126 size. If the space for the stack is less than 16 bytes aslink trows a
8129 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8130 the 8051. Option 'y' for memory summary output file.
8132 Changes to sdcc (All the changes are marked with 'JCF'):
8134 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8136 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8137 overlaying area for it (uses RegBankUsed[4]).
8139 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8140 bank zero as used by default. By default aslink locates the stack
8141 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8142 the creation of the .mem file. Delegates the allocation of data area
8143 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8144 the begining of the stack area to aslink.
8146 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8147 glue() in SDCCglue.c creates an area for it.
8149 2002-09-03 Borut Razem <borut.razem AT siol.net>
8150 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8151 sdcc/src/pic/glue.c:
8152 introduced atexit() handler for teporay files removal in case of
8153 errors, assertions, ...
8155 2002-08-29 Borut Razem <borut.razem AT siol.net>
8156 * sdcc/support/cpp2/auto-host_vc_in.h:
8157 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8158 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8159 Maybe there is a similar problem with BORLANDC? It should be checked!
8161 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8162 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8163 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8164 was not executed, and the compiler (cl) launched a warning:
8165 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8167 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8168 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8170 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8171 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8173 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8174 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8175 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8176 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8177 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8178 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8179 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8180 - added Release configuration in VS projects
8181 - review of compiler an linker options
8182 - VC .exe files are generated in bin_vc directory, not to interfere
8183 with binaries generated from other projects (cygwin, mingw, bcc ...)
8185 * sdcc/src/yacc.dsp: added
8187 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8188 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8189 and insert the version number definitions from .version
8191 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8193 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8194 added - genarate auto-host.h using auto-host_vc_in.h as template
8197 removed from CVS, generated automatically
8199 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8200 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8202 2002-08-11 Borut Razem <borut.razem AT siol.net>
8203 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8205 2002-08-10 Borut Razem <borut.razem AT siol.net>
8206 * src/SDCCmain.c (main):
8207 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8208 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8209 The consequence was that some temporary files were not removed.
8212 unification of code in functions tempfilename() and tempfile():
8213 function tempnam() is defined in Visual Studio 6.0 and .NET
8215 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8217 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8218 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8219 - removed compiler command line option /WX: Treats all warnings as errors
8220 - update a list of source files, included into the project
8222 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8223 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8224 changed project type to Generic Project so that can be correcly converted to VS.NET project
8226 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8228 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8230 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8232 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8233 added return 0 statements after assert() to make compiler happy
8235 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8236 added newline in the def file to keep MSC compiler satisfied
8238 * sdcc/src/z80/gen.c:
8239 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8240 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8241 - solved MSC error in function aopDump()
8243 * sdcc_vc.h: define PREFIX as "\\sdcc"
8245 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8246 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8248 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8249 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8250 - Rewrote the register banking algorithm.
