2754 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2756 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2757 loaded with the linker search paths (-L arguments) and the libraries
2758 to be linked with the current source (-l arguments). Changes
2759 currently will affect only the pic16 port.
2760 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2761 include path the port specific paths and port specific libraries,
2762 * gplink command now contains the $3 argument,
2763 * src/pic16/device.h,
2764 * src/pic16/device.c,: structure PIC_device is made public and
2765 renamed to PIC16_device, the same for variable Pics which is renamed
2766 to Pics16. Updated all references to them.
2767 * src/pic16/glue.c (pic16glue): corrected bug with code
2768 initialization which bypassed the variable initializations block.

2778 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2780 Documenting changes from previous commits.
2781 * configure.in (version 1.56),
2782 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2783 when generating output files to configure the pic16 library,
2784 but now I've commented it out, since gputils aren't installed in the
2785 SF compile farm, so library won't compile
2787 * device/lib/Makefile.in (version 1.56): initially I've added in
2788 target 'all' the prerequestive 'model-pic16' so it compiled the
2789 pic16 library, but now I've commented it out for the same reasons
2791 * added targets 'model-pic16' and 'objects-pic16' to compile the
2793 * added target 'port-specific-objects-pic16' to handle the
2794 generated libraries and copy them into the build/ directory
2795 * added target 'clean-intermediate-pic16' to clean intermediate
2796 files into pic16 directory
2797 * in target 'installdirs' added line to create directory pic16 in
2798 the installation path
2800 * device/include/Makefile.in (version 1.11): in target 'install'
2801 added lines to copy all header files to installation path,
2802 * in target 'installdirs' added line create directory for pic16
2803 headers in the installation path

2818 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2819 option so that it actually works. Made it specific to the z80, since
2820 the gbz80 doesn't have these kinds of I/O ports.
2822 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2824 * device/include/z180.h,

2837 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2839 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2840 changed interrupt vector table generation to only emit declared vectors.
2841 * device/include/Makefile.in: added missing backslash
2842 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
2844 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2846 Mainly changes to support compilation of the device libraries
2847 * src/pic16/device.c: stack is allocated via symbol and not
2848 via literal number. The symbol is placed in the corresponding
2849 position of the data ram
2850 * (pic16_dump_section): relocatable and absolute uninitialized
2851 data are now emitted in sorted order to reduce section naming,
2852 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2853 weren't marked as being in the access bank,
2855 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2857 Added portion of GNU PIC Library under the directory
2858 device/include/pic16 and device/lib/pic16. These files
2859 contain the declarations of SFRs for the PIC18Fxx2 devices.
2860 The directory is initialized via configure from toplevel.
2862 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2864 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2865 the spilllocations to be compared correctly
2867 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2869 * src/SDCCast.c (decorateType): fixed bug introduced today
2871 2004-01-12 Borut Razem <borut.razem AT siol.net>
2873 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2876 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2878 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
2879 in simpler and even better code
2881 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
2883 * src/SDCCicode.c (operandOperation): fixed bug #874819

2889 * doc/sdccman.lyx: Moved and added some sections, small changes
2890 all over. Telling LaTeX to be less strict with word spacing
2891 to better keep the right margin. Changed some notes about
2892 maintainance of the ports in section 3.2.1 - is it OK like this?
2894 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2896 SDCC source changes:
2897 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2930 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
2931 UPPER for immediate operands,
2932 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2934 * src/pic16/peeph.def: all peepholes with movff are commented out,
2935 because there is a problem in the pcode peep optimizer,
2936 * src/pic16/ralloc.c: the register allocator can now reuse local
2937 function symbols for another function. This saves register usage.
2938 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2940 Added file src/pic16/NOTES with information about program writing on
2941 the current port version.

2950 * src/SDCCmain.c : fixed #872250: -l command line defined library
2951 files are scanned before standard library files
2953 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2970 gen51Code): more efficient parameter receive for --model-large
2973 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2976 * src/z80/main.c: added missed needLinkerScript flags (more than
2977 one port structure defined in these file)
2978 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2981 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

2984 * src/port.h: added flag needLinkerScript in port->linker
2985 structure to inform whether to create a .lnk file or not,
2993 * src/z80/main.c: changed appropriately to configure
2994 needLinkerScript flag
2996 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2997 * src/pic/glue.c: added variable udata_section_name to
2998 override default uninitialized data segment definition for
2999 devices only with SHAREBANK memory (reported from Erik Epetrich)
3000 * (pic14emitOverlay): modified to emit a commented overlay segment
3001 directive when no overlay data exist
3002 * (picglue): modified to emit uninitialized data segment
3003 according to udata_section_name
3004 * src/pic/main.c (_pic14_parseOptions): added command line

3008 arguments via -W option
3009 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3010 object file from '.rel' to '.o' in port->linker structure,
3011 changed size of fptr from 2 to 3 in port structure
3013 2004-01-07 Borut Razem <borut.razem AT siol.net>
3015 * support/scripts/sdcc.nsi: update PATH
3016 * support/scripts/sdcc.ico: craeted
3018 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
3020 * device/include/Makefile.in: fix install
3021 * doc/Makefile: fix install
3023 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3025 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3027 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3028 how the function variable allocation summary is displayed; also
3029 include information about variables allocated to the overlay
3032 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3034 * as/mcs51/lkmain.c: Help about -Y option

3044 LEFT_OP (left shift)
3046 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3048 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3049 (default behaviour).
3051 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3053 A python script to validate compiler diagnostic messages. It can be
3054 used to verify that sdcc complains about bad c source code and
3055 gives a good location of the error.
3056 * support/valdiag/Makefile,
3057 * support/valdiag/valdiag.py,
3058 * support/valdiag/tests/*
3060 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3062 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3063 * src/SDCCsymt.c (newEnumType),
3065 * support/Util/SDCCerr.c,
3066 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported

3071 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3073 * src/common.h: added ifndef/define/endif macros
3074 around the header file.
3075 Bug reported from Jesus Calvino-Fraga
3077 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3079 * sdcc.spec: updated
3080 * device/include/Makefile.in: don't install CVS directories
3081 * device/lib/Makefile.in: added removal of CVS directories after install
3082 * doc/Makefile: fixed install, added local_icons
3083 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3084 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3085 * src/ds390/gen.c (genRightShift): fixed bug #870788
3086 * src/SDCCast.c (decorateType): fixed bug #870781
3088 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3090 PIC16 port related changes:
3091 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3092 added variable stackPos,
3094 * gen.c: genCall, assignResultValue: added support for
3095 pushing/retrieving function parameters to/from stack,
3096 genFunction,genEndFunction: setup stack frame for the
3098 genAddrOf: will be changed according to bug 863624
3100 * added files genutils.c and genutils.h which contain gen*
3101 debugged and optimised functions extracted from gen.c
3103 * glue.c: added variable 'externs' which holds extern symbols,
3104 pic16emitRegularMap: is modified to properly handle relocatable
3105 symbols under the new scheme,
3106 pic16createInterruptVect: is modified
3107 pic16printPublics: is modified to emit 'global' assembler directives,
3108 added pic16_printExterns to print extern symbols,
3109 pic16glue: initializes stack/frame pointer in the beginning of
3110 the assembly output. Temporary hack, will be corrected later,
3111 because gplink yet does not support stack and SDCC does not
3112 yet support a type of crt0.o object to create the final binary.
3114 * Removed many lines that contain 8051 legacy code.
3115 * The code is finally placed under a 'code' directive.
3116 * Added port specific options.
3118 * _process_pragma: simplified since now we do not need *special*
3119 include file to define SFR registers. But a separate header
3120 will be needed. This will be developed later.
3121 * _pic16_parseOptions: added, parses port specific options:
3122 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3123 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3124 --preplace-udata-with=
3126 * _pic16_setDefaultOptions: modified to initialize section names,
3127 but hack is temporarly out of order since it needs improvement.
3128 * _pic16_genAssemblerPreamble: configuration words are emitted by
3129 their address instead of their name. This part is incomplete and
3130 supports only the 18Fxx2 devices. Other devices will emit an error
3131 during assembly since they do not contain the same set of config
3133 * _pic16_genIVT: is modified,
3135 * pcode.c: added definitions for some hardware registers that are needed
3137 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3138 All PCI entries are updated. Now LFSR is supported.
3139 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3140 * added pic16_newpCodeOpLit2 to support instructions with
3141 two literal arguments
3142 * pic16_pCode2str: corrected code that emits assembler instructions
3143 with two literal operands and those that have an access bit modifier
3144 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3145 this fixes a bug which caused some labels to be lost, when an
3146 assembler directive was added, i.e. banksel,
3147 * pic16_FixRegisterBanking: improved logic that causes the insertion
3149 * InlineFunction: functions that are called once, are not any more
3150 inlined. This can be a port option in the future,
3152 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3154 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3155 hold the corresponding uninitialized symbols,
3156 * pic16_allocProcessorRegister: registers have explicit marked the
3158 * pic16_allocInternalRegister: registers are explicit marked as
3160 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3161 processing list, so bit registers were lost,
3164 * ralloc.h: added field 'accessBank' and original symbol operand
3165 in register definition,
3166 * removed the field isMapped from register definition,
3168 ** Several functions have been removed from various sources:
3169 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3170 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3171 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3172 pic16_assignRelocatableRegisters
3174 ** others have been introduced:
3175 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3176 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3178 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3180 * support/scripts/inc2h.pl: changed definition of BIT_AT
3181 to emit 'sbit at' instead of 'bit at'. This was a request.
3183 PIC16 port related preliminary changes:
3184 * gen.c: prefixed function popRegFromString with
3185 pic16_ and all references to it corrected
3186 * pcode.c: all pic16_pc_* hardware registers prefixed
3187 with underscore (_),
3188 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3189 * ralloc.c: newReg(): when register is REG_SFR then
3190 set address to rIdx,
3191 pic16_allocProcessorRegister(): marks register wasUsed=0
3192 pic16_writeUsedRegs(): added a call to assign processor
3193 registers via pic16_assignFixedRegisters
3195 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3197 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3198 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3199 variables in unused register banks. Also the SSEG is placed
3200 wherever there is enough space for it, and IDATA can be anywhere
3201 in internal RAM. For now compile using -Wl-Y[stack_size].
3202 The mem file is different for this option as well, since it
3203 makes no sense of talking about DSEG lenght.
3205 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3207 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3208 in certain cases, e.g. when ROM assignment, patch provided
3209 from Albert den Haan.
3211 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
3213 Many signedness and type propagation fixes:
3214 * src/SDCCicode.c: made geniCodeCast() static
3215 replaced SPEC_ by IS_ (cosmetic)
3216 (operandOperation): fixed div and mod operation
3217 (usualBinaryConversions): added support for promotion of char
3218 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
3219 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
3220 (geniCodeAdd): an array index will stay unsigned, even if promoted

4217 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4218 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4219 If they pop r0/r1 they must be called in the opposite order than aopOp().
4220 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4221 (resp. --stack-auto), prepared for --xstack

4227 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4229 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
4230 these ports have their own __sdcc_external_start()
4232 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4234 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4235 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4236 type for bits was changed. It resulted in bit variables becoming
4237 global, which is not permitted in PIC 14 assembly output.
4239 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4241 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4243 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4245 Z80 and MCS51 linkers complaint if a public symbol is defined
4246 in more than one library module:

4254 A few small changes that speed up the peephole optimizer.
4258 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4260 Try to make the peephole optimizer smarter by maintaining
4261 an association between the assembly source code and the
4262 iCodes that originated them. Put this information to use
4263 with a new peephole rule condition "notVolatile" so that
4264 the rules can be aggressive yet still safe.
4269 * src/mcs51/peeph.def
4271 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4275 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4276 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4277 if the left or right operand symbols have the accuse flag set.
4279 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4281 Changed the type of the result of the ! (NOT) operator to char;
4282 previously it returned the same type as the source. This allows
4283 us to eliminate all the genFloatNot functions (all of its target
4284 implementations were very buggy) since !float can use the same
4287 * src/SDCCicode.c (ast2iCode): ! returns char
4288 * src/mcs51/gen.c (genNot, genNotFloat),
4289 * src/ds390/gen.c (genNot, genNotFloat),
4290 * src/z80/gen.c (genNot, genNotFloat),
4291 * src/pic/gen.c (genNot, genNotFloat),
4292 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

4296 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4297 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4298 during interrupts. Ensure WSAVE is located at a shared bank address.
4299 2. Fixed page selection in some places
4300 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4301 the registers name strings.
4302 4. Fixed "signed / unsigned compare" compiler warnings.
4303 5. The PIC port manages its own allocation of the general purpose
4304 registers, but makes no attempt to reuse them. As a result when
4305 compiling it soon runs out of general purpose registers. Some
4306 additional code was added to the files pcode.c and device.c to walk
4307 through the function call tree and rename the registers so that they
4317 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4318 genPlus() & genMinus() when the result is the same as left or right

4324 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4326 Made bitfield a distinct type from bit so that bitfields
4327 convert as per ANSI C and bits retain their traditional
4328 boolean style behaviour. Implemented bitfield support in
4336 * src/ds390/gen.c: bit v bitfield split
4337 * src/z80/gen.c: New support for bitfields
4338 * support/regression/tests/bitfields.c: reenabled z80,
4341 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4343 Rules 246.x, 247.x relate to bitfields, the others speed up
4344 access to xdata mapped I/O devices.
4346 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4348 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4350 Cleaned up genPackBits and genUnpackBits and added two helper
4351 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4352 for literal assignments in genPackBits (thanks to Frieder for
4358 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4360 Fixed bug #748310 (pointer to function type mishandled when the
4361 function name is omitted). Also fixed a SIGSEGV when a function
4362 attribute (reentrant, etc) is used on a non-function or on a
4363 function but misplaced before the parameter list.
4365 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4367 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4390 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4392 Made the constant following the "interrupt" keyword optional. If
4393 omitted, the function will not automatically be given an entry
4394 in the interrupt vector table (similar to #pragma NOIV, but
4395 less syntacticly kludgy). The interrupt number is also now
4396 range checked. Also fixed a bug in the high order bit example
4403 * support/Util/SDCCerr.c
4404 * support/Util/SDCCerr.h
4407 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4410 * src/SDCCicode.c (operandOperation): rewritten some ops
4411 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4412 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4414 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4415 be re-activated by defining REDUCE_LITERALS)
4416 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4417 unsigned, but are signed by default
4418 * src/SDCCval.c (constVal): rearranged
4419 * src/SDCCval.c (valMod): preliminary fix
4420 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4872 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4873 the regression tests I'm not brave enough to enable 245.b, 245.c
4874 * doc/sdccman.lyx: added latex preamble for hyperref package.
4875 Using pdflatex this will give you a hyperlinked pdf file with
4876 bookmarks. (prepend '%' before /usepackage if this breaks something)

4892 Applied patch from bug 737905 (renamed yylineo to mylineno):
4899 * src/pic16/pcode.c: Cleaned warnings
4900 * src/pic16/pcodeflow.c: Cleaned warnings
4901 * src/pic16/pcoderegs.c: Cleaned warnings

4917 it can be defined with CFLAGS when running configure
4918 * src/SDCCmain.c: fixed compiling + linking with object files
4920 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4923 added --disable-pic16-port
4924 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4925 * src/SDCCmain.c: linkOptions is changed to set *,
4926 added if/endif conditional macros to remove options help
4927 messages from optionsTable when a port is not configured, added
4928 support for the PIc16 port in the ports table, when executing
4929 the compiler with no port specified on command line, a default
4930 port is selected with the new macro DEFAULT_PORT which is
4931 defined in port.h, in setDefaultOptions() linkOptions is removed
4932 from initialization assignment, since now it is a set,
4933 parseCmdLine uses setParseWithComma for linkOptions, in
4934 linkEdit() linkOptions are accessed with new function indexSet()
4935 which returns the i'th item of a set variable. See SDCCset.c, in
4936 linkEdit() when calling buildCmdLine(), added linkOptions as
4937 last argument. Now users can pass arguments to gplink via the
4938 -Wl option, main() uses pic16glue() to glue up pic16 programs

4950 * src/pic16/glue.c: commented out some error producing lines
4951 * src/pic16/main.c: __config directives are commented out to stop
4952 gpasm complaining and test the linkage with gplink, _linkCmd and
4953 _asmCmd changed to be more gplink and gpasm friendly
4954 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4955 produced an error when parsed, peep rule 12 is added to utilize
4956 movff, but it is commented out since the pCode does not support
4957 yet a command with 2 address arguments
4959 2003-05-18 <johan AT balder>
4961 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4962 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4986 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4988 2003-05-11 Borut Razem <borut.razem AT siol.net>
4990 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4991 the path of bin directory, so that PATH is the only env. variable, which has to be set
4992 in case of standard installation.
4993 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6022 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6024 * in \sdcc\as\mcs51\ changed these files in order to create an
6025 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6026 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6027 following files to include the previous two files: aslink.dsp,
6028 Makefile.aslink, Makefile.bcc, and Makefile.in.
6030 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6031 .adb instead of .cdb
6033 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6035 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6036 value from option --iram-size.
6038 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6040 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6043 2002-09-18 <wiml AT hhhh.org>
6045 * SDCClrange.h: exposed setFromRange() and setToRange()
6046 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6047 packRegsForAccUse() (bug 542397)
6048 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6049 multiple times and emitting the fetch operations more than once
6050 added aopGetUsesAcc() function to allow binary operators to
6051 fetch their operands in the correct order; made genMinus() emit
6052 compact code for X = LITERAL - Y
6054 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6055 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6056 sprintf() in line 1267.
6058 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6059 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6062 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6063 Changes to aslink (All the changes are marked with 'JCF'):
6065 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6068 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6069 area BSEG. Also moves, if possible, the DATA area down into the internal
6070 ram so more space is available.
6072 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6075 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6076 not bytes. Function summary() which creates a memory usage summary
6077 file with extension .mem. Reports of overlaping stack and small stack
6078 size. If the space for the stack is less than 16 bytes aslink trows a
6081 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6082 the 8051. Option 'y' for memory summary output file.
6084 Changes to sdcc (All the changes are marked with 'JCF'):
6086 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6088 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6089 overlaying area for it (uses RegBankUsed[4]).
6091 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6092 bank zero as used by default. By default aslink locates the stack
6093 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6094 the creation of the .mem file. Delegates the allocation of data area
6095 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6096 the begining of the stack area to aslink.
6098 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6099 glue() in SDCCglue.c creates an area for it.
6101 2002-09-03 Borut Razem <borut.razem AT siol.net>
6102 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6103 sdcc/src/pic/glue.c:
6104 introduced atexit() handler for teporay files removal in case of
6105 errors, assertions, ...
6107 2002-08-29 Borut Razem <borut.razem AT siol.net>
6108 * sdcc/support/cpp2/auto-host_vc_in.h:
6109 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6110 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6111 Maybe there is a similar problem with BORLANDC? It should be checked!
6113 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6114 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6115 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6116 was not executed, and the compiler (cl) launched a warning:
6117 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6119 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6120 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6122 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

6129 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6130 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6131 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6132 - added Release configuration in VS projects
6133 - review of compiler an linker options
6134 - VC .exe files are generated in bin_vc directory, not to interfere
6135 with binaries generated from other projects (cygwin, mingw, bcc ...)
6137 * sdcc/src/yacc.dsp: added
6139 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6140 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6141 and insert the version number definitions from .version
6143 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6145 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6151 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6152 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6154 2002-08-11 Borut Razem <borut.razem AT siol.net>
6155 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6157 2002-08-10 Borut Razem <borut.razem AT siol.net>
6158 * src/SDCCmain.c (main):
6159 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6160 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6161 The consequence was that some temporary files were not removed.
6164 unification of code in functions tempfilename() and tempfile():
6165 function tempnam() is defined in Visual Studio 6.0 and .NET
6167 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6169 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6170 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6171 - removed compiler command line option /WX: Treats all warnings as errors
6172 - update a list of source files, included into the project
6174 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6175 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6176 changed project type to Generic Project so that can be correcly converted to VS.NET project
6178 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6180 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

6184 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6185 added return 0 statements after assert() to make compiler happy
6187 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6188 added newline in the def file to keep MSC compiler satisfied
6190 * sdcc/src/z80/gen.c:
6191 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6192 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6193 - solved MSC error in function aopDump()
6195 * sdcc_vc.h: define PREFIX as "\\sdcc"
6197 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

6249 Initialized the new field char *Processor field to NULL in all ports
6252 Compiler generated registers for interrupt context saving
6253 were not getting allocated.
6255 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6258 Fixed left shift. Will promote the left side of a left shift
6259 if a) left shifting more than size of operand or b) when assigned
6260 to something size > size of left side
6262 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6370 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6372 * sdcc/src/SDCCloop.c:
6373 Previous fix was not good. basic blocks that have "break" or "return" are
6374 not really partof a loop , but live ranges used in these blocks should
6375 be live thru the entire loop, so set partOfLoop but don't add them to
6378 2002-02-21 <johan AT FRIJA>
6380 * src/SDCCcse.c: fixed bug #514308
6382 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
