2738 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2739 strtof is not part of C89 and isn't included with Mac OS X.
2741 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2765 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
2768 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2770 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2771 loaded with the linker search paths (-L arguments) and the libraries
2772 to be linked with the current source (-l arguments). Changes
2773 currently will affect only the pic16 port.
2774 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2775 include path the port specific paths and port specific libraries,
2776 * gplink command now contains the $3 argument,
2777 * src/pic16/device.h,
2778 * src/pic16/device.c,: structure PIC_device is made public and
2779 renamed to PIC16_device, the same for variable Pics which is renamed
2780 to Pics16. Updated all references to them.
2781 * src/pic16/glue.c (pic16glue): corrected bug with code
2782 initialization which bypassed the variable initializations block.
2784 * device/lib/pic16/Makefile.rules: removed --penable-stack from
2785 COMPILE_FLAGS and added the --nostdinc option
2787 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2789 * device/include/mc68hc908jb8.h: Register defs for another member

2792 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2794 Documenting changes from previous commits.
2795 * configure.in (version 1.56),
2796 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2797 when generating output files to configure the pic16 library,
2798 but now I've commented it out, since gputils aren't installed in the
2799 SF compile farm, so library won't compile
2801 * device/lib/Makefile.in (version 1.56): initially I've added in
2802 target 'all' the prerequestive 'model-pic16' so it compiled the
2803 pic16 library, but now I've commented it out for the same reasons
2805 * added targets 'model-pic16' and 'objects-pic16' to compile the
2807 * added target 'port-specific-objects-pic16' to handle the
2808 generated libraries and copy them into the build/ directory
2809 * added target 'clean-intermediate-pic16' to clean intermediate
2810 files into pic16 directory
2811 * in target 'installdirs' added line to create directory pic16 in
2812 the installation path
2814 * device/include/Makefile.in (version 1.11): in target 'install'
2815 added lines to copy all header files to installation path,
2816 * in target 'installdirs' added line create directory for pic16
2817 headers in the installation path
2819 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

2832 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2833 option so that it actually works. Made it specific to the z80, since
2834 the gbz80 doesn't have these kinds of I/O ports.
2836 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2838 * device/include/z180.h,

2851 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2853 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2854 changed interrupt vector table generation to only emit declared vectors.
2855 * device/include/Makefile.in: added missing backslash
2856 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
2858 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2860 Mainly changes to support compilation of the device libraries
2861 * src/pic16/device.c: stack is allocated via symbol and not
2862 via literal number. The symbol is placed in the corresponding
2863 position of the data ram
2864 * (pic16_dump_section): relocatable and absolute uninitialized
2865 data are now emitted in sorted order to reduce section naming,
2866 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2867 weren't marked as being in the access bank,
2869 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2871 Added portion of GNU PIC Library under the directory
2872 device/include/pic16 and device/lib/pic16. These files
2873 contain the declarations of SFRs for the PIC18Fxx2 devices.
2874 The directory is initialized via configure from toplevel.
2876 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2878 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2879 the spilllocations to be compared correctly
2881 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2883 * src/SDCCast.c (decorateType): fixed bug introduced today
2885 2004-01-12 Borut Razem <borut.razem AT siol.net>
2887 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2890 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2892 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
2893 in simpler and even better code
2895 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
2897 * src/SDCCicode.c (operandOperation): fixed bug #874819

2903 * doc/sdccman.lyx: Moved and added some sections, small changes
2904 all over. Telling LaTeX to be less strict with word spacing
2905 to better keep the right margin. Changed some notes about
2906 maintainance of the ports in section 3.2.1 - is it OK like this?
2908 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2910 SDCC source changes:
2911 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2944 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
2945 UPPER for immediate operands,
2946 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2948 * src/pic16/peeph.def: all peepholes with movff are commented out,
2949 because there is a problem in the pcode peep optimizer,
2950 * src/pic16/ralloc.c: the register allocator can now reuse local
2951 function symbols for another function. This saves register usage.
2952 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2954 Added file src/pic16/NOTES with information about program writing on
2955 the current port version.

2964 * src/SDCCmain.c : fixed #872250: -l command line defined library
2965 files are scanned before standard library files
2967 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2984 gen51Code): more efficient parameter receive for --model-large
2987 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2990 * src/z80/main.c: added missed needLinkerScript flags (more than
2991 one port structure defined in these file)
2992 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2995 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

3008 needLinkerScript flag
3010 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3011 * src/pic/glue.c: added variable udata_section_name to
3012 override default uninitialized data segment definition for
3013 devices only with SHAREBANK memory (reported from Erik Epetrich)
3014 * (pic14emitOverlay): modified to emit a commented overlay segment
3015 directive when no overlay data exist
3016 * (picglue): modified to emit uninitialized data segment
3017 according to udata_section_name

3022 arguments via -W option
3023 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3024 object file from '.rel' to '.o' in port->linker structure,
3025 changed size of fptr from 2 to 3 in port structure
3027 2004-01-07 Borut Razem <borut.razem AT siol.net>
3029 * support/scripts/sdcc.nsi: update PATH
3030 * support/scripts/sdcc.ico: craeted
3032 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
3034 * device/include/Makefile.in: fix install
3035 * doc/Makefile: fix install
3037 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3039 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3041 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3042 how the function variable allocation summary is displayed; also
3043 include information about variables allocated to the overlay
3046 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3048 * as/mcs51/lkmain.c: Help about -Y option

3057 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3058 LEFT_OP (left shift)
3060 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3062 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3063 (default behaviour).
3065 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3067 A python script to validate compiler diagnostic messages. It can be
3068 used to verify that sdcc complains about bad c source code and
3069 gives a good location of the error.
3070 * support/valdiag/Makefile,
3071 * support/valdiag/valdiag.py,
3072 * support/valdiag/tests/*
3074 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3076 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3077 * src/SDCCsymt.c (newEnumType),
3079 * support/Util/SDCCerr.c,
3080 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3082 * support/regression/tests/enum.c: added test for enum values that

3085 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3087 * src/common.h: added ifndef/define/endif macros
3088 around the header file.
3089 Bug reported from Jesus Calvino-Fraga
3091 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3093 * sdcc.spec: updated
3094 * device/include/Makefile.in: don't install CVS directories
3095 * device/lib/Makefile.in: added removal of CVS directories after install
3096 * doc/Makefile: fixed install, added local_icons
3097 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3098 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3099 * src/ds390/gen.c (genRightShift): fixed bug #870788
3100 * src/SDCCast.c (decorateType): fixed bug #870781
3102 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3104 PIC16 port related changes:
3105 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3106 added variable stackPos,
3108 * gen.c: genCall, assignResultValue: added support for
3109 pushing/retrieving function parameters to/from stack,
3110 genFunction,genEndFunction: setup stack frame for the
3112 genAddrOf: will be changed according to bug 863624
3114 * added files genutils.c and genutils.h which contain gen*
3115 debugged and optimised functions extracted from gen.c
3117 * glue.c: added variable 'externs' which holds extern symbols,
3118 pic16emitRegularMap: is modified to properly handle relocatable
3119 symbols under the new scheme,
3120 pic16createInterruptVect: is modified
3121 pic16printPublics: is modified to emit 'global' assembler directives,
3122 added pic16_printExterns to print extern symbols,
3123 pic16glue: initializes stack/frame pointer in the beginning of
3124 the assembly output. Temporary hack, will be corrected later,
3125 because gplink yet does not support stack and SDCC does not
3126 yet support a type of crt0.o object to create the final binary.
3128 * Removed many lines that contain 8051 legacy code.
3129 * The code is finally placed under a 'code' directive.
3130 * Added port specific options.
3132 * _process_pragma: simplified since now we do not need *special*
3133 include file to define SFR registers. But a separate header
3134 will be needed. This will be developed later.
3135 * _pic16_parseOptions: added, parses port specific options:
3136 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3137 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3138 --preplace-udata-with=
3140 * _pic16_setDefaultOptions: modified to initialize section names,
3141 but hack is temporarly out of order since it needs improvement.
3142 * _pic16_genAssemblerPreamble: configuration words are emitted by
3143 their address instead of their name. This part is incomplete and
3144 supports only the 18Fxx2 devices. Other devices will emit an error
3145 during assembly since they do not contain the same set of config
3147 * _pic16_genIVT: is modified,
3149 * pcode.c: added definitions for some hardware registers that are needed
3151 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3152 All PCI entries are updated. Now LFSR is supported.
3153 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3154 * added pic16_newpCodeOpLit2 to support instructions with
3155 two literal arguments
3156 * pic16_pCode2str: corrected code that emits assembler instructions
3157 with two literal operands and those that have an access bit modifier
3158 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3159 this fixes a bug which caused some labels to be lost, when an
3160 assembler directive was added, i.e. banksel,
3161 * pic16_FixRegisterBanking: improved logic that causes the insertion
3163 * InlineFunction: functions that are called once, are not any more
3164 inlined. This can be a port option in the future,
3166 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3168 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3169 hold the corresponding uninitialized symbols,
3170 * pic16_allocProcessorRegister: registers have explicit marked the
3172 * pic16_allocInternalRegister: registers are explicit marked as
3174 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3175 processing list, so bit registers were lost,
3178 * ralloc.h: added field 'accessBank' and original symbol operand
3179 in register definition,
3180 * removed the field isMapped from register definition,
3182 ** Several functions have been removed from various sources:
3183 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3184 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3185 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3186 pic16_assignRelocatableRegisters
3188 ** others have been introduced:
3189 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3190 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3192 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3194 * support/scripts/inc2h.pl: changed definition of BIT_AT
3195 to emit 'sbit at' instead of 'bit at'. This was a request.
3197 PIC16 port related preliminary changes:
3198 * gen.c: prefixed function popRegFromString with
3199 pic16_ and all references to it corrected
3200 * pcode.c: all pic16_pc_* hardware registers prefixed
3201 with underscore (_),
3202 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3203 * ralloc.c: newReg(): when register is REG_SFR then
3204 set address to rIdx,
3205 pic16_allocProcessorRegister(): marks register wasUsed=0
3206 pic16_writeUsedRegs(): added a call to assign processor
3207 registers via pic16_assignFixedRegisters
3209 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3211 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3212 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3213 variables in unused register banks. Also the SSEG is placed
3214 wherever there is enough space for it, and IDATA can be anywhere
3215 in internal RAM. For now compile using -Wl-Y[stack_size].
3216 The mem file is different for this option as well, since it
3217 makes no sense of talking about DSEG lenght.
3219 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3221 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4221 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
4222 before instructions that use the _STATUS register
4224 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
4226 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4227 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4228 fetching of the pointer
4229 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4230 copied from genNearPointerSet()
4231 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4232 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4233 If they pop r0/r1 they must be called in the opposite order than aopOp().
4234 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4235 (resp. --stack-auto), prepared for --xstack
4237 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4241 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4243 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
4244 these ports have their own __sdcc_external_start()
4246 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4248 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4249 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4250 type for bits was changed. It resulted in bit variables becoming
4251 global, which is not permitted in PIC 14 assembly output.
4253 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4255 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4257 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4259 Z80 and MCS51 linkers complaint if a public symbol is defined

4268 A few small changes that speed up the peephole optimizer.
4272 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4274 Try to make the peephole optimizer smarter by maintaining
4275 an association between the assembly source code and the
4276 iCodes that originated them. Put this information to use
4277 with a new peephole rule condition "notVolatile" so that
4278 the rules can be aggressive yet still safe.
4283 * src/mcs51/peeph.def
4285 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4289 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4290 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4291 if the left or right operand symbols have the accuse flag set.
4293 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4295 Changed the type of the result of the ! (NOT) operator to char;
4296 previously it returned the same type as the source. This allows
4297 us to eliminate all the genFloatNot functions (all of its target
4298 implementations were very buggy) since !float can use the same
4301 * src/SDCCicode.c (ast2iCode): ! returns char
4302 * src/mcs51/gen.c (genNot, genNotFloat),
4303 * src/ds390/gen.c (genNot, genNotFloat),
4304 * src/z80/gen.c (genNot, genNotFloat),
4305 * src/pic/gen.c (genNot, genNotFloat),
4306 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

4310 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4311 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4312 during interrupts. Ensure WSAVE is located at a shared bank address.
4313 2. Fixed page selection in some places
4314 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4315 the registers name strings.
4316 4. Fixed "signed / unsigned compare" compiler warnings.
4317 5. The PIC port manages its own allocation of the general purpose
4318 registers, but makes no attempt to reuse them. As a result when
4319 compiling it soon runs out of general purpose registers. Some
4320 additional code was added to the files pcode.c and device.c to walk
4321 through the function call tree and rename the registers so that they
4331 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4332 genPlus() & genMinus() when the result is the same as left or right

4338 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4340 Made bitfield a distinct type from bit so that bitfields
4341 convert as per ANSI C and bits retain their traditional
4342 boolean style behaviour. Implemented bitfield support in
4350 * src/ds390/gen.c: bit v bitfield split
4351 * src/z80/gen.c: New support for bitfields
4352 * support/regression/tests/bitfields.c: reenabled z80,
4355 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4357 Rules 246.x, 247.x relate to bitfields, the others speed up
4358 access to xdata mapped I/O devices.
4360 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4362 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4364 Cleaned up genPackBits and genUnpackBits and added two helper
4365 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4366 for literal assignments in genPackBits (thanks to Frieder for
4372 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4374 Fixed bug #748310 (pointer to function type mishandled when the
4375 function name is omitted). Also fixed a SIGSEGV when a function
4376 attribute (reentrant, etc) is used on a non-function or on a
4377 function but misplaced before the parameter list.
4379 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4381 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4382 * support/Util/SDCCerr.h,
4383 * support/Util/SDCCerr.c: Added func attr misuse error msg

4404 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4406 Made the constant following the "interrupt" keyword optional. If
4407 omitted, the function will not automatically be given an entry
4408 in the interrupt vector table (similar to #pragma NOIV, but
4409 less syntacticly kludgy). The interrupt number is also now
4410 range checked. Also fixed a bug in the high order bit example
4417 * support/Util/SDCCerr.c
4418 * support/Util/SDCCerr.h
4421 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4424 * src/SDCCicode.c (operandOperation): rewritten some ops
4425 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4426 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4428 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4429 be re-activated by defining REDUCE_LITERALS)
4430 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4431 unsigned, but are signed by default
4432 * src/SDCCval.c (constVal): rearranged
4433 * src/SDCCval.c (valMod): preliminary fix
4434 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4939 * src/SDCCmain.c: linkOptions is changed to set *,
4940 added if/endif conditional macros to remove options help
4941 messages from optionsTable when a port is not configured, added
4942 support for the PIc16 port in the ports table, when executing
4943 the compiler with no port specified on command line, a default
4944 port is selected with the new macro DEFAULT_PORT which is
4945 defined in port.h, in setDefaultOptions() linkOptions is removed
4946 from initialization assignment, since now it is a set,
4947 parseCmdLine uses setParseWithComma for linkOptions, in
4948 linkEdit() linkOptions are accessed with new function indexSet()
4949 which returns the i'th item of a set variable. See SDCCset.c, in
4950 linkEdit() when calling buildCmdLine(), added linkOptions as
4951 last argument. Now users can pass arguments to gplink via the
4952 -Wl option, main() uses pic16glue() to glue up pic16 programs

4964 * src/pic16/glue.c: commented out some error producing lines
4965 * src/pic16/main.c: __config directives are commented out to stop
4966 gpasm complaining and test the linkage with gplink, _linkCmd and
4967 _asmCmd changed to be more gplink and gpasm friendly
4968 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4969 produced an error when parsed, peep rule 12 is added to utilize
4970 movff, but it is commented out since the pCode does not support
4971 yet a command with 2 address arguments
4973 2003-05-18 <johan AT balder>
4975 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5002 2003-05-11 Borut Razem <borut.razem AT siol.net>
5004 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5005 the path of bin directory, so that PATH is the only env. variable, which has to be set
5006 in case of standard installation.

6036 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6038 * in \sdcc\as\mcs51\ changed these files in order to create an
6039 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6040 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6041 following files to include the previous two files: aslink.dsp,
6042 Makefile.aslink, Makefile.bcc, and Makefile.in.
6044 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6045 .adb instead of .cdb
6047 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6049 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6050 value from option --iram-size.
6052 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6054 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6057 2002-09-18 <wiml AT hhhh.org>
6059 * SDCClrange.h: exposed setFromRange() and setToRange()
6060 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6061 packRegsForAccUse() (bug 542397)
6062 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6063 multiple times and emitting the fetch operations more than once
6064 added aopGetUsesAcc() function to allow binary operators to
6065 fetch their operands in the correct order; made genMinus() emit
6066 compact code for X = LITERAL - Y
6068 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6069 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6070 sprintf() in line 1267.
6072 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6073 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6076 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6077 Changes to aslink (All the changes are marked with 'JCF'):
6079 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6082 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6083 area BSEG. Also moves, if possible, the DATA area down into the internal
6084 ram so more space is available.
6086 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6089 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6090 not bytes. Function summary() which creates a memory usage summary
6091 file with extension .mem. Reports of overlaping stack and small stack
6092 size. If the space for the stack is less than 16 bytes aslink trows a
6095 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6096 the 8051. Option 'y' for memory summary output file.
6098 Changes to sdcc (All the changes are marked with 'JCF'):
6100 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6102 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6103 overlaying area for it (uses RegBankUsed[4]).
6105 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6106 bank zero as used by default. By default aslink locates the stack
6107 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6108 the creation of the .mem file. Delegates the allocation of data area
6109 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6110 the begining of the stack area to aslink.
6112 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6113 glue() in SDCCglue.c creates an area for it.
6115 2002-09-03 Borut Razem <borut.razem AT siol.net>
6116 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6117 sdcc/src/pic/glue.c:
6118 introduced atexit() handler for teporay files removal in case of
6119 errors, assertions, ...
6121 2002-08-29 Borut Razem <borut.razem AT siol.net>
6122 * sdcc/support/cpp2/auto-host_vc_in.h:
6123 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6124 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6125 Maybe there is a similar problem with BORLANDC? It should be checked!
6127 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6128 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6129 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6130 was not executed, and the compiler (cl) launched a warning:
6131 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6133 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6134 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

6141 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6142 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6143 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6144 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6145 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6146 - added Release configuration in VS projects
6147 - review of compiler an linker options
6148 - VC .exe files are generated in bin_vc directory, not to interfere
6149 with binaries generated from other projects (cygwin, mingw, bcc ...)
6151 * sdcc/src/yacc.dsp: added
6153 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6154 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6155 and insert the version number definitions from .version
6157 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6159 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6169 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6171 2002-08-10 Borut Razem <borut.razem AT siol.net>
6172 * src/SDCCmain.c (main):
6173 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6174 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6175 The consequence was that some temporary files were not removed.
6178 unification of code in functions tempfilename() and tempfile():
6179 function tempnam() is defined in Visual Studio 6.0 and .NET
6181 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6183 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6184 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

6199 added return 0 statements after assert() to make compiler happy
6201 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6202 added newline in the def file to keep MSC compiler satisfied
6204 * sdcc/src/z80/gen.c:
6205 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6206 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6207 - solved MSC error in function aopDump()
6209 * sdcc_vc.h: define PREFIX as "\\sdcc"
6211 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

6263 Initialized the new field char *Processor field to NULL in all ports
6266 Compiler generated registers for interrupt context saving
6267 were not getting allocated.
6269 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6272 Fixed left shift. Will promote the left side of a left shift
6273 if a) left shifting more than size of operand or b) when assigned
6274 to something size > size of left side
6276 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6386 * sdcc/src/SDCCloop.c:
6387 Previous fix was not good. basic blocks that have "break" or "return" are
6388 not really partof a loop , but live ranges used in these blocks should
6389 be live thru the entire loop, so set partOfLoop but don't add them to
6392 2002-02-21 <johan AT FRIJA>
