874 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
876 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
878 2005-03-26 Raphael Neider <rneider AT web.de>
880 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
881 if condition == CARRY)
882 * (genCmp): adapted to new genSkipc semantics
883 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
884 on rIfx (genCmp was broken)
886 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
888 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
889 * src/z80/main.c (_keywords[]),
890 * src/SDCCglobal.h (struct options),
892 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
893 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
894 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
895 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
896 always available in leading double underscore form. The C99 support is
897 mostly missing, but it's a start.
898 * support/regression/tests/bug-227710.c: fixed nonconforming use of
899 reserved identifier "__data".
901 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

947 2005-03-20 Borut Razem <borut.razem AT siol.net>
949 * support/scripts/inc2h.pl: WIN32 port

955 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
957 * device/include/stdint.h: added
958 * device/lib/abs.c: added

975 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
977 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
979 * device/lib/printf_large.c: removed inline assembly for portability and
980 readability. Use printf_fast if speed or size are more important.
981 * src/pic16/gen.c: removed conditions around use of DEBUGpc
982 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
984 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
986 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
987 prevent compiler warning
989 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
991 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
992 moved to level 0 and declared as static. Also they are explicit
993 placed in access bank. This was necessery because some times they
994 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
995 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
996 optimizations. Currently only compare to unsigned char is implemented,
997 * src/pic16/gen.c: added fReturnIdx array,
998 * (struct resolvedIfx) is moved to gen.h and made public,
999 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1000 * (aopForSym): added an optimization to directly store in stack of
1001 the operand of a SEND iCode,
1002 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1003 but as registers instead (AOP_REG) using the fReturnIdx array,
1004 * (pic16_freeAsmop): remove the freed register from the
1005 _G.sregsAlloc field,
1006 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1007 a compare of 'WREG',
1008 * (pic16_popGetTempRegCond): changed function prototype, now
1009 function takes also a bitVector argument v which holds the current
1010 set of registers that are allocated for stack access by aopForSym,
1011 registers allocated in aopForSym for accessing stack symbols are not
1012 any more part of the functions usedRegs field,
1013 * (genCall): some times aopOp is called for a stack variable to be
1014 send, aopForSym might perform the push, if this is true make sure
1015 that genCall doesn't push the variable twice by testing _G.resDirect,
1016 * (genFunction): changed testing for unspecified interrupt number
1017 from 256 to INTNO_UNSPEC,
1018 * modified selection scheme of frame pointer generation. Previously
1019 if function did use local registers a frame pointer was generated,
1020 now a frame pointer is generated only if function has arguments
1021 (that need PLUSW2 register access), or has stack arguments, or the
1022 compiler is not instructed to omit the frame pointer,
1023 * (genEndFunction): before restoring local registers that were saved
1024 in the function preamble, also restore the registers that *might*
1025 have been allocated for stack access,
1026 * (genRet): removed some old comments,
1027 * (genCmp, the active (RN's) version): added a call to the
1028 pic16_genCmp_special function to perform the compare with a more
1029 robust and optimized way,
1030 * (genInline): a feature has been added in inline code generation,
1031 which allows a wildcard variable substitution when writing inline
1032 assembly. Code is incomplete and experimental therefore undocumented,
1033 * (genCast): changed order of aopOp for result and right to allow
1034 aopForSym to directly load the result if possible,
1035 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1036 perform an optimized compare on some selected special occasions,
1037 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1038 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1039 generate an IVT any more,
1040 * src/pic16/main.c (pic16_optionsTable): added command line option
1042 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1043 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1045 * src/pic16/NOTES: Raphael Neider added in list of active developers
1046 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1047 jumptable_end to prevent bug #,
1048 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1049 inCond and outCond fields,
1050 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1051 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1052 turn off register spilling,
1053 * (packRegsForOneUse): synced with other ports' versions although it
1054 is not used currently,
1055 * (pic16_packRegisters): added an optimization while reading
1056 structure bitfields, some registers may be saved (malloc code is
1057 decreased by 80 bytes)
1059 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1061 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1062 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1063 this can be optimized more?
1065 2005-03-10 Raphael Neider <rneider AT web.de>
1067 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1068 genNearPointerGet): (hopefully) fixed access to bitfields via
1069 pointers (p->bitN = x; and x = p->bitN; failed)
1071 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1258 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1259 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1260 this might fix SIGSEGVs on MinGW...
1261 * src/SDCCopt.c (killDeadCode): restored original behaviour
1262 (volatile operands might get thrown away though)
1264 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1704 generated for switch statements. For now you need to set the
1705 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1706 Now 4 algorithms for mcs51 jumptable generation are used:
1707 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4787 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4789 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4790 loaded with the linker search paths (-L arguments) and the libraries
4791 to be linked with the current source (-l arguments). Changes
4792 currently will affect only the pic16 port.
4793 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4794 include path the port specific paths and port specific libraries,
4795 * gplink command now contains the $3 argument,
4796 * src/pic16/device.h,
4797 * src/pic16/device.c,: structure PIC_device is made public and
4798 renamed to PIC16_device, the same for variable Pics which is renamed

4813 Documenting changes from previous commits.
4814 * configure.in (version 1.56),
4815 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4816 when generating output files to configure the pic16 library,
4817 but now I've commented it out, since gputils aren't installed in the
4818 SF compile farm, so library won't compile
4820 * device/lib/Makefile.in (version 1.56): initially I've added in
4821 target 'all' the prerequestive 'model-pic16' so it compiled the
4822 pic16 library, but now I've commented it out for the same reasons
4824 * added targets 'model-pic16' and 'objects-pic16' to compile the
4826 * added target 'port-specific-objects-pic16' to handle the
4827 generated libraries and copy them into the build/ directory
4828 * added target 'clean-intermediate-pic16' to clean intermediate
4829 files into pic16 directory
4830 * in target 'installdirs' added line to create directory pic16 in
4831 the installation path
4833 * device/include/Makefile.in (version 1.11): in target 'install'
4834 added lines to copy all header files to installation path,
4835 * in target 'installdirs' added line create directory for pic16
4836 headers in the installation path

4851 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4852 option so that it actually works. Made it specific to the z80, since
4853 the gbz80 doesn't have these kinds of I/O ports.
4855 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4881 via literal number. The symbol is placed in the corresponding
4882 position of the data ram
4883 * (pic16_dump_section): relocatable and absolute uninitialized
4884 data are now emitted in sorted order to reduce section naming,
4885 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4886 weren't marked as being in the access bank,
4888 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4890 Added portion of GNU PIC Library under the directory
4891 device/include/pic16 and device/lib/pic16. These files
4892 contain the declarations of SFRs for the PIC18Fxx2 devices.

4923 all over. Telling LaTeX to be less strict with word spacing
4924 to better keep the right margin. Changed some notes about
4925 maintainance of the ports in section 3.2.1 - is it OK like this?
4927 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4965 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4967 * src/pic16/peeph.def: all peepholes with movff are commented out,
4968 because there is a problem in the pcode peep optimizer,
4969 * src/pic16/ralloc.c: the register allocator can now reuse local

5046 2004-01-07 Borut Razem <borut.razem AT siol.net>
5048 * support/scripts/sdcc.nsi: update PATH
5049 * support/scripts/sdcc.ico: craeted

5062 include information about variables allocated to the overlay
5065 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5067 * as/mcs51/lkmain.c: Help about -Y option

5079 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5081 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5082 (default behaviour).
5084 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5086 A python script to validate compiler diagnostic messages. It can be
5087 used to verify that sdcc complains about bad c source code and
5088 gives a good location of the error.
5089 * support/valdiag/Makefile,
5090 * support/valdiag/valdiag.py,
5091 * support/valdiag/tests/*
5093 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5095 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5106 * src/common.h: added ifndef/define/endif macros
5107 around the header file.
5108 Bug reported from Jesus Calvino-Fraga
5110 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5112 * sdcc.spec: updated
5113 * device/include/Makefile.in: don't install CVS directories
5114 * device/lib/Makefile.in: added removal of CVS directories after install
5115 * doc/Makefile: fixed install, added local_icons
5116 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5117 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5118 * src/ds390/gen.c (genRightShift): fixed bug #870788
5119 * src/SDCCast.c (decorateType): fixed bug #870781
5121 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5123 PIC16 port related changes:
5124 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5125 added variable stackPos,
5127 * gen.c: genCall, assignResultValue: added support for
5128 pushing/retrieving function parameters to/from stack,
5129 genFunction,genEndFunction: setup stack frame for the
5131 genAddrOf: will be changed according to bug 863624
5133 * added files genutils.c and genutils.h which contain gen*
5134 debugged and optimised functions extracted from gen.c
5136 * glue.c: added variable 'externs' which holds extern symbols,
5137 pic16emitRegularMap: is modified to properly handle relocatable
5138 symbols under the new scheme,
5139 pic16createInterruptVect: is modified
5140 pic16printPublics: is modified to emit 'global' assembler directives,
5141 added pic16_printExterns to print extern symbols,
5142 pic16glue: initializes stack/frame pointer in the beginning of
5143 the assembly output. Temporary hack, will be corrected later,
5144 because gplink yet does not support stack and SDCC does not
5145 yet support a type of crt0.o object to create the final binary.
5147 * Removed many lines that contain 8051 legacy code.
5148 * The code is finally placed under a 'code' directive.
5149 * Added port specific options.
5151 * _process_pragma: simplified since now we do not need *special*
5152 include file to define SFR registers. But a separate header
5153 will be needed. This will be developed later.
5154 * _pic16_parseOptions: added, parses port specific options:
5155 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5156 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5157 --preplace-udata-with=
5159 * _pic16_setDefaultOptions: modified to initialize section names,
5160 but hack is temporarly out of order since it needs improvement.
5161 * _pic16_genAssemblerPreamble: configuration words are emitted by
5162 their address instead of their name. This part is incomplete and
5163 supports only the 18Fxx2 devices. Other devices will emit an error
5164 during assembly since they do not contain the same set of config
5166 * _pic16_genIVT: is modified,
5168 * pcode.c: added definitions for some hardware registers that are needed
5170 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5171 All PCI entries are updated. Now LFSR is supported.
5172 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5173 * added pic16_newpCodeOpLit2 to support instructions with
5174 two literal arguments
5175 * pic16_pCode2str: corrected code that emits assembler instructions
5176 with two literal operands and those that have an access bit modifier
5177 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5178 this fixes a bug which caused some labels to be lost, when an
5179 assembler directive was added, i.e. banksel,
5180 * pic16_FixRegisterBanking: improved logic that causes the insertion
5182 * InlineFunction: functions that are called once, are not any more
5183 inlined. This can be a port option in the future,
5185 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5187 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5188 hold the corresponding uninitialized symbols,
5189 * pic16_allocProcessorRegister: registers have explicit marked the
5191 * pic16_allocInternalRegister: registers are explicit marked as
5193 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5194 processing list, so bit registers were lost,
5197 * ralloc.h: added field 'accessBank' and original symbol operand
5198 in register definition,
5199 * removed the field isMapped from register definition,
5201 ** Several functions have been removed from various sources:
5202 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5203 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5204 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5205 pic16_assignRelocatableRegisters
5207 ** others have been introduced:
5208 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5209 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5211 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5213 * support/scripts/inc2h.pl: changed definition of BIT_AT
5214 to emit 'sbit at' instead of 'bit at'. This was a request.
5216 PIC16 port related preliminary changes:
5217 * gen.c: prefixed function popRegFromString with
5218 pic16_ and all references to it corrected
5219 * pcode.c: all pic16_pc_* hardware registers prefixed
5220 with underscore (_),
5221 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5222 * ralloc.c: newReg(): when register is REG_SFR then
5223 set address to rIdx,
5224 pic16_allocProcessorRegister(): marks register wasUsed=0
5225 pic16_writeUsedRegs(): added a call to assign processor
5226 registers via pic16_assignFixedRegisters
5228 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5230 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5231 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5232 variables in unused register banks. Also the SSEG is placed
5233 wherever there is enough space for it, and IDATA can be anywhere
5234 in internal RAM. For now compile using -Wl-Y[stack_size].
5235 The mem file is different for this option as well, since it
5236 makes no sense of talking about DSEG lenght.
5238 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5240 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5241 in certain cases, e.g. when ROM assignment, patch provided
5242 from Albert den Haan.
5244 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5487 it breaks with bitfields, extern declarations, and gcse analysis.
5488 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5489 could be assigned through a pointer, so don't complain.

6267 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6268 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6269 type for bits was changed. It resulted in bit variables becoming
6270 global, which is not permitted in PIC 14 assembly output.

6287 A few small changes that speed up the peephole optimizer.
6291 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6293 Try to make the peephole optimizer smarter by maintaining
6294 an association between the assembly source code and the
6295 iCodes that originated them. Put this information to use
6296 with a new peephole rule condition "notVolatile" so that
6297 the rules can be aggressive yet still safe.
6302 * src/mcs51/peeph.def
6304 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6308 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6309 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6310 if the left or right operand symbols have the accuse flag set.
6312 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6314 Changed the type of the result of the ! (NOT) operator to char;
6315 previously it returned the same type as the source. This allows
6316 us to eliminate all the genFloatNot functions (all of its target
6317 implementations were very buggy) since !float can use the same

6329 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6330 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6331 during interrupts. Ensure WSAVE is located at a shared bank address.
6332 2. Fixed page selection in some places
6333 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6334 the registers name strings.
6335 4. Fixed "signed / unsigned compare" compiler warnings.
6336 5. The PIC port manages its own allocation of the general purpose
6337 registers, but makes no attempt to reuse them. As a result when
6338 compiling it soon runs out of general purpose registers. Some
6339 additional code was added to the files pcode.c and device.c to walk
6340 through the function call tree and rename the registers so that they
6350 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6351 genPlus() & genMinus() when the result is the same as left or right

6357 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6359 Made bitfield a distinct type from bit so that bitfields
6360 convert as per ANSI C and bits retain their traditional
6361 boolean style behaviour. Implemented bitfield support in

6377 access to xdata mapped I/O devices.
6379 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6381 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6383 Cleaned up genPackBits and genUnpackBits and added two helper
6384 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6385 for literal assignments in genPackBits (thanks to Frieder for
6391 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6393 Fixed bug #748310 (pointer to function type mishandled when the
6394 function name is omitted). Also fixed a SIGSEGV when a function
6395 attribute (reentrant, etc) is used on a non-function or on a
6396 function but misplaced before the parameter list.

6425 Made the constant following the "interrupt" keyword optional. If
6426 omitted, the function will not automatically be given an entry
6427 in the interrupt vector table (similar to #pragma NOIV, but
6428 less syntacticly kludgy). The interrupt number is also now
6429 range checked. Also fixed a bug in the high order bit example

6450 unsigned, but are signed by default
6451 * src/SDCCval.c (constVal): rearranged
6452 * src/SDCCval.c (valMod): preliminary fix
6453 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6947 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6949 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6950 it can be defined with CFLAGS when running configure
6951 * src/SDCCmain.c: fixed compiling + linking with object files
6953 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6955 * configure.in: configure for pic16 port,
6956 added --disable-pic16-port
6957 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6958 * src/SDCCmain.c: linkOptions is changed to set *,
6959 added if/endif conditional macros to remove options help
6960 messages from optionsTable when a port is not configured, added
6961 support for the PIc16 port in the ports table, when executing
6962 the compiler with no port specified on command line, a default
6963 port is selected with the new macro DEFAULT_PORT which is
6964 defined in port.h, in setDefaultOptions() linkOptions is removed
6965 from initialization assignment, since now it is a set,
6966 parseCmdLine uses setParseWithComma for linkOptions, in
6967 linkEdit() linkOptions are accessed with new function indexSet()
6968 which returns the i'th item of a set variable. See SDCCset.c, in
6969 linkEdit() when calling buildCmdLine(), added linkOptions as
6970 last argument. Now users can pass arguments to gplink via the
6971 -Wl option, main() uses pic16glue() to glue up pic16 programs
6972 * src/SDCCpeeph.c: various changes to support pic16

6983 * src/pic16/glue.c: commented out some error producing lines
6984 * src/pic16/main.c: __config directives are commented out to stop
6985 gpasm complaining and test the linkage with gplink, _linkCmd and
6986 _asmCmd changed to be more gplink and gpasm friendly
6987 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6988 produced an error when parsed, peep rule 12 is added to utilize
6989 movff, but it is commented out since the pCode does not support
6990 yet a command with 2 address arguments
6992 2003-05-18 <johan AT balder>
6994 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7021 2003-05-11 Borut Razem <borut.razem AT siol.net>
7023 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7024 the path of bin directory, so that PATH is the only env. variable, which has to be set

8012 2003-01-07 <johan AT balder>
8014 * src/SDCCast.c (decorateType): fixed bug #600035

8029 * src/SDCCicode.c: fixed array add
8031 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8032 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8033 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8035 2003-01-04 <johan AT balder>
8037 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8039 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8040 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8042 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8043 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8050 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8052 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8053 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8055 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8057 * in \sdcc\as\mcs51\ changed these files in order to create an
8058 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8059 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8060 following files to include the previous two files: aslink.dsp,
8061 Makefile.aslink, Makefile.bcc, and Makefile.in.
8063 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8064 .adb instead of .cdb
8066 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8068 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8069 value from option --iram-size.
8071 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8073 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8076 2002-09-18 <wiml AT hhhh.org>
8078 * SDCClrange.h: exposed setFromRange() and setToRange()
8079 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8080 packRegsForAccUse() (bug 542397)
8081 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8082 multiple times and emitting the fetch operations more than once
8083 added aopGetUsesAcc() function to allow binary operators to
8084 fetch their operands in the correct order; made genMinus() emit
8085 compact code for X = LITERAL - Y
8087 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8088 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8089 sprintf() in line 1267.
8091 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8092 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8095 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8096 Changes to aslink (All the changes are marked with 'JCF'):
8098 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8101 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8102 area BSEG. Also moves, if possible, the DATA area down into the internal
8103 ram so more space is available.
8105 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8108 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8109 not bytes. Function summary() which creates a memory usage summary
8110 file with extension .mem. Reports of overlaping stack and small stack
8111 size. If the space for the stack is less than 16 bytes aslink trows a
8114 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8115 the 8051. Option 'y' for memory summary output file.
8117 Changes to sdcc (All the changes are marked with 'JCF'):
8119 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8121 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8122 overlaying area for it (uses RegBankUsed[4]).
8124 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8125 bank zero as used by default. By default aslink locates the stack
8126 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8127 the creation of the .mem file. Delegates the allocation of data area
8128 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8129 the begining of the stack area to aslink.
8131 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8132 glue() in SDCCglue.c creates an area for it.
8134 2002-09-03 Borut Razem <borut.razem AT siol.net>
8135 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8136 sdcc/src/pic/glue.c:
8137 introduced atexit() handler for teporay files removal in case of
8138 errors, assertions, ...
8140 2002-08-29 Borut Razem <borut.razem AT siol.net>
8141 * sdcc/support/cpp2/auto-host_vc_in.h:
8142 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8143 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8144 Maybe there is a similar problem with BORLANDC? It should be checked!
8146 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8147 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8148 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8149 was not executed, and the compiler (cl) launched a warning:
8150 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8152 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8153 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8155 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8156 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8158 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8159 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8160 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8161 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8162 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8163 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8164 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8165 - added Release configuration in VS projects
8166 - review of compiler an linker options
8167 - VC .exe files are generated in bin_vc directory, not to interfere
8168 with binaries generated from other projects (cygwin, mingw, bcc ...)
8170 * sdcc/src/yacc.dsp: added
8172 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8173 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8174 and insert the version number definitions from .version
8176 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8178 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8179 added - genarate auto-host.h using auto-host_vc_in.h as template
8182 removed from CVS, generated automatically
8184 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8185 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8187 2002-08-11 Borut Razem <borut.razem AT siol.net>
8188 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8190 2002-08-10 Borut Razem <borut.razem AT siol.net>
8191 * src/SDCCmain.c (main):
8192 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8193 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8194 The consequence was that some temporary files were not removed.
8197 unification of code in functions tempfilename() and tempfile():
8198 function tempnam() is defined in Visual Studio 6.0 and .NET
8200 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8202 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8203 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8204 - removed compiler command line option /WX: Treats all warnings as errors
8205 - update a list of source files, included into the project
8207 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8208 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8209 changed project type to Generic Project so that can be correcly converted to VS.NET project
8211 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8213 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8215 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8217 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8218 added return 0 statements after assert() to make compiler happy
8220 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8221 added newline in the def file to keep MSC compiler satisfied
8223 * sdcc/src/z80/gen.c:
8224 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8225 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8226 - solved MSC error in function aopDump()
8228 * sdcc_vc.h: define PREFIX as "\\sdcc"
8230 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8231 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8233 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8234 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8235 - Rewrote the register banking algorithm.
8236 - Added pCode live-range analysis to registers (for now, only non-used and
8237 singly-used registers optimized away)
8239 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8241 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
8243 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8244 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8246 2002-04-22 Michael Hope <michaelh AT vroom>
8248 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
