2759 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2761 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2762 loaded with the linker search paths (-L arguments) and the libraries
2763 to be linked with the current source (-l arguments). Changes
2764 currently will affect only the pic16 port.
2765 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2766 include path the port specific paths and port specific libraries,
2767 * gplink command now contains the $3 argument,
2768 * src/pic16/device.h,
2769 * src/pic16/device.c,: structure PIC_device is made public and
2770 renamed to PIC16_device, the same for variable Pics which is renamed
2771 to Pics16. Updated all references to them.
2772 * src/pic16/glue.c (pic16glue): corrected bug with code
2773 initialization which bypassed the variable initializations block.
2775 * device/lib/pic16/Makefile.rules: removed --penable-stack from
2776 COMPILE_FLAGS and added the --nostdinc option
2778 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2780 * device/include/mc68hc908jb8.h: Register defs for another member

2783 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2785 Documenting changes from previous commits.
2786 * configure.in (version 1.56),
2787 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2788 when generating output files to configure the pic16 library,
2789 but now I've commented it out, since gputils aren't installed in the
2790 SF compile farm, so library won't compile
2792 * device/lib/Makefile.in (version 1.56): initially I've added in
2793 target 'all' the prerequestive 'model-pic16' so it compiled the
2794 pic16 library, but now I've commented it out for the same reasons
2796 * added targets 'model-pic16' and 'objects-pic16' to compile the
2798 * added target 'port-specific-objects-pic16' to handle the
2799 generated libraries and copy them into the build/ directory
2800 * added target 'clean-intermediate-pic16' to clean intermediate
2801 files into pic16 directory
2802 * in target 'installdirs' added line to create directory pic16 in
2803 the installation path
2805 * device/include/Makefile.in (version 1.11): in target 'install'
2806 added lines to copy all header files to installation path,
2807 * in target 'installdirs' added line create directory for pic16
2808 headers in the installation path
2810 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

2823 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2824 option so that it actually works. Made it specific to the z80, since
2825 the gbz80 doesn't have these kinds of I/O ports.
2827 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2829 * device/include/z180.h,

2842 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2844 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2845 changed interrupt vector table generation to only emit declared vectors.
2846 * device/include/Makefile.in: added missing backslash
2847 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

2851 Mainly changes to support compilation of the device libraries
2852 * src/pic16/device.c: stack is allocated via symbol and not
2853 via literal number. The symbol is placed in the corresponding
2854 position of the data ram
2855 * (pic16_dump_section): relocatable and absolute uninitialized
2856 data are now emitted in sorted order to reduce section naming,
2857 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2858 weren't marked as being in the access bank,
2860 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2862 Added portion of GNU PIC Library under the directory
2863 device/include/pic16 and device/lib/pic16. These files
2864 contain the declarations of SFRs for the PIC18Fxx2 devices.
2865 The directory is initialized via configure from toplevel.
2867 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2869 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2870 the spilllocations to be compared correctly
2872 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2874 * src/SDCCast.c (decorateType): fixed bug introduced today
2876 2004-01-12 Borut Razem <borut.razem AT siol.net>
2878 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2881 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2883 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
2884 in simpler and even better code
2886 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
2888 * src/SDCCicode.c (operandOperation): fixed bug #874819

2892 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2894 * doc/sdccman.lyx: Moved and added some sections, small changes
2895 all over. Telling LaTeX to be less strict with word spacing
2896 to better keep the right margin. Changed some notes about
2897 maintainance of the ports in section 3.2.1 - is it OK like this?
2899 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2901 SDCC source changes:
2902 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2935 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
2936 UPPER for immediate operands,
2937 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2939 * src/pic16/peeph.def: all peepholes with movff are commented out,
2940 because there is a problem in the pcode peep optimizer,
2941 * src/pic16/ralloc.c: the register allocator can now reuse local
2942 function symbols for another function. This saves register usage.
2943 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2945 Added file src/pic16/NOTES with information about program writing on
2946 the current port version.

2953 2004-01-09 Borut Razem <borut.razem AT siol.net>
2955 * src/SDCCmain.c : fixed #872250: -l command line defined library
2956 files are scanned before standard library files
2958 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2972 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2974 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
2975 gen51Code): more efficient parameter receive for --model-large
2978 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2981 * src/z80/main.c: added missed needLinkerScript flags (more than
2982 one port structure defined in these file)
2983 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2986 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

2989 * src/port.h: added flag needLinkerScript in port->linker
2990 structure to inform whether to create a .lnk file or not,
2998 * src/z80/main.c: changed appropriately to configure
2999 needLinkerScript flag
3001 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3002 * src/pic/glue.c: added variable udata_section_name to
3003 override default uninitialized data segment definition for
3004 devices only with SHAREBANK memory (reported from Erik Epetrich)
3005 * (pic14emitOverlay): modified to emit a commented overlay segment
3006 directive when no overlay data exist
3007 * (picglue): modified to emit uninitialized data segment
3008 according to udata_section_name

3014 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3015 object file from '.rel' to '.o' in port->linker structure,
3016 changed size of fptr from 2 to 3 in port structure
3018 2004-01-07 Borut Razem <borut.razem AT siol.net>
3020 * support/scripts/sdcc.nsi: update PATH
3021 * support/scripts/sdcc.ico: craeted
3023 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
3025 * device/include/Makefile.in: fix install
3026 * doc/Makefile: fix install
3028 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3030 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3032 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3033 how the function variable allocation summary is displayed; also
3034 include information about variables allocated to the overlay
3037 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3039 * as/mcs51/lkmain.c: Help about -Y option

3049 LEFT_OP (left shift)
3051 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3053 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3054 (default behaviour).
3056 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3058 A python script to validate compiler diagnostic messages. It can be
3059 used to verify that sdcc complains about bad c source code and
3060 gives a good location of the error.
3061 * support/valdiag/Makefile,
3062 * support/valdiag/valdiag.py,
3063 * support/valdiag/tests/*
3065 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3067 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3068 * src/SDCCsymt.c (newEnumType),
3070 * support/Util/SDCCerr.c,
3071 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3073 * support/regression/tests/enum.c: added test for enum values that

3076 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3078 * src/common.h: added ifndef/define/endif macros
3079 around the header file.
3080 Bug reported from Jesus Calvino-Fraga
3082 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3084 * sdcc.spec: updated
3085 * device/include/Makefile.in: don't install CVS directories
3086 * device/lib/Makefile.in: added removal of CVS directories after install
3087 * doc/Makefile: fixed install, added local_icons
3088 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3089 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3090 * src/ds390/gen.c (genRightShift): fixed bug #870788
3091 * src/SDCCast.c (decorateType): fixed bug #870781
3093 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3095 PIC16 port related changes:
3096 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3097 added variable stackPos,
3099 * gen.c: genCall, assignResultValue: added support for
3100 pushing/retrieving function parameters to/from stack,
3101 genFunction,genEndFunction: setup stack frame for the
3103 genAddrOf: will be changed according to bug 863624
3105 * added files genutils.c and genutils.h which contain gen*
3106 debugged and optimised functions extracted from gen.c
3108 * glue.c: added variable 'externs' which holds extern symbols,
3109 pic16emitRegularMap: is modified to properly handle relocatable
3110 symbols under the new scheme,
3111 pic16createInterruptVect: is modified
3112 pic16printPublics: is modified to emit 'global' assembler directives,
3113 added pic16_printExterns to print extern symbols,
3114 pic16glue: initializes stack/frame pointer in the beginning of
3115 the assembly output. Temporary hack, will be corrected later,
3116 because gplink yet does not support stack and SDCC does not
3117 yet support a type of crt0.o object to create the final binary.
3119 * Removed many lines that contain 8051 legacy code.
3120 * The code is finally placed under a 'code' directive.
3121 * Added port specific options.
3123 * _process_pragma: simplified since now we do not need *special*
3124 include file to define SFR registers. But a separate header
3125 will be needed. This will be developed later.
3126 * _pic16_parseOptions: added, parses port specific options:
3127 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3128 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3129 --preplace-udata-with=
3131 * _pic16_setDefaultOptions: modified to initialize section names,
3132 but hack is temporarly out of order since it needs improvement.
3133 * _pic16_genAssemblerPreamble: configuration words are emitted by
3134 their address instead of their name. This part is incomplete and
3135 supports only the 18Fxx2 devices. Other devices will emit an error
3136 during assembly since they do not contain the same set of config
3138 * _pic16_genIVT: is modified,
3140 * pcode.c: added definitions for some hardware registers that are needed
3142 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3143 All PCI entries are updated. Now LFSR is supported.
3144 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3145 * added pic16_newpCodeOpLit2 to support instructions with
3146 two literal arguments
3147 * pic16_pCode2str: corrected code that emits assembler instructions
3148 with two literal operands and those that have an access bit modifier
3149 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3150 this fixes a bug which caused some labels to be lost, when an
3151 assembler directive was added, i.e. banksel,
3152 * pic16_FixRegisterBanking: improved logic that causes the insertion
3154 * InlineFunction: functions that are called once, are not any more
3155 inlined. This can be a port option in the future,
3157 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3159 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3160 hold the corresponding uninitialized symbols,
3161 * pic16_allocProcessorRegister: registers have explicit marked the
3163 * pic16_allocInternalRegister: registers are explicit marked as
3165 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3166 processing list, so bit registers were lost,
3169 * ralloc.h: added field 'accessBank' and original symbol operand
3170 in register definition,
3171 * removed the field isMapped from register definition,
3173 ** Several functions have been removed from various sources:
3174 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3175 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3176 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3177 pic16_assignRelocatableRegisters
3179 ** others have been introduced:
3180 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3181 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3183 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3185 * support/scripts/inc2h.pl: changed definition of BIT_AT
3186 to emit 'sbit at' instead of 'bit at'. This was a request.
3188 PIC16 port related preliminary changes:
3189 * gen.c: prefixed function popRegFromString with
3190 pic16_ and all references to it corrected
3191 * pcode.c: all pic16_pc_* hardware registers prefixed
3192 with underscore (_),
3193 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3194 * ralloc.c: newReg(): when register is REG_SFR then
3195 set address to rIdx,
3196 pic16_allocProcessorRegister(): marks register wasUsed=0
3197 pic16_writeUsedRegs(): added a call to assign processor
3198 registers via pic16_assignFixedRegisters
3200 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3202 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3203 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3204 variables in unused register banks. Also the SSEG is placed
3205 wherever there is enough space for it, and IDATA can be anywhere
3206 in internal RAM. For now compile using -Wl-Y[stack_size].
3207 The mem file is different for this option as well, since it
3208 makes no sense of talking about DSEG lenght.
3210 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3212 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3213 in certain cases, e.g. when ROM assignment, patch provided
3214 from Albert den Haan.
3216 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
3218 Many signedness and type propagation fixes:
3219 * src/SDCCicode.c: made geniCodeCast() static
3220 replaced SPEC_ by IS_ (cosmetic)
3221 (operandOperation): fixed div and mod operation
3222 (usualBinaryConversions): added support for promotion of char
3223 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
3224 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)

4220 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4221 copied from genNearPointerSet()
4222 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4223 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4224 If they pop r0/r1 they must be called in the opposite order than aopOp().
4225 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4226 (resp. --stack-auto), prepared for --xstack

4235 these ports have their own __sdcc_external_start()
4237 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4239 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4240 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4241 type for bits was changed. It resulted in bit variables becoming
4242 global, which is not permitted in PIC 14 assembly output.
4244 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4246 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4248 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4250 Z80 and MCS51 linkers complaint if a public symbol is defined

4259 A few small changes that speed up the peephole optimizer.
4263 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4265 Try to make the peephole optimizer smarter by maintaining
4266 an association between the assembly source code and the
4267 iCodes that originated them. Put this information to use
4268 with a new peephole rule condition "notVolatile" so that
4269 the rules can be aggressive yet still safe.
4274 * src/mcs51/peeph.def
4276 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4280 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4281 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4282 if the left or right operand symbols have the accuse flag set.
4284 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4286 Changed the type of the result of the ! (NOT) operator to char;
4287 previously it returned the same type as the source. This allows
4288 us to eliminate all the genFloatNot functions (all of its target
4289 implementations were very buggy) since !float can use the same
4292 * src/SDCCicode.c (ast2iCode): ! returns char
4293 * src/mcs51/gen.c (genNot, genNotFloat),
4294 * src/ds390/gen.c (genNot, genNotFloat),
4295 * src/z80/gen.c (genNot, genNotFloat),
4296 * src/pic/gen.c (genNot, genNotFloat),
4297 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

4301 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4302 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4303 during interrupts. Ensure WSAVE is located at a shared bank address.
4304 2. Fixed page selection in some places
4305 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4306 the registers name strings.
4307 4. Fixed "signed / unsigned compare" compiler warnings.
4308 5. The PIC port manages its own allocation of the general purpose
4309 registers, but makes no attempt to reuse them. As a result when
4310 compiling it soon runs out of general purpose registers. Some
4311 additional code was added to the files pcode.c and device.c to walk
4312 through the function call tree and rename the registers so that they
4322 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4323 genPlus() & genMinus() when the result is the same as left or right

4329 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4331 Made bitfield a distinct type from bit so that bitfields
4332 convert as per ANSI C and bits retain their traditional
4333 boolean style behaviour. Implemented bitfield support in
4341 * src/ds390/gen.c: bit v bitfield split
4342 * src/z80/gen.c: New support for bitfields
4343 * support/regression/tests/bitfields.c: reenabled z80,
4346 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4348 Rules 246.x, 247.x relate to bitfields, the others speed up
4349 access to xdata mapped I/O devices.
4351 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4353 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4355 Cleaned up genPackBits and genUnpackBits and added two helper
4356 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4357 for literal assignments in genPackBits (thanks to Frieder for
4363 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4365 Fixed bug #748310 (pointer to function type mishandled when the
4366 function name is omitted). Also fixed a SIGSEGV when a function
4367 attribute (reentrant, etc) is used on a non-function or on a
4368 function but misplaced before the parameter list.
4370 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4372 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4395 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4397 Made the constant following the "interrupt" keyword optional. If
4398 omitted, the function will not automatically be given an entry
4399 in the interrupt vector table (similar to #pragma NOIV, but
4400 less syntacticly kludgy). The interrupt number is also now
4401 range checked. Also fixed a bug in the high order bit example
4408 * support/Util/SDCCerr.c
4409 * support/Util/SDCCerr.h
4412 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4415 * src/SDCCicode.c (operandOperation): rewritten some ops
4416 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4417 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4419 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4420 be re-activated by defining REDUCE_LITERALS)
4421 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4422 unsigned, but are signed by default
4423 * src/SDCCval.c (constVal): rearranged
4424 * src/SDCCval.c (valMod): preliminary fix
4425 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4877 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4878 the regression tests I'm not brave enough to enable 245.b, 245.c
4879 * doc/sdccman.lyx: added latex preamble for hyperref package.
4880 Using pdflatex this will give you a hyperlinked pdf file with
4881 bookmarks. (prepend '%' before /usepackage if this breaks something)

4897 Applied patch from bug 737905 (renamed yylineo to mylineno):
4904 * src/pic16/pcode.c: Cleaned warnings
4905 * src/pic16/pcodeflow.c: Cleaned warnings
4906 * src/pic16/pcoderegs.c: Cleaned warnings

4922 it can be defined with CFLAGS when running configure
4923 * src/SDCCmain.c: fixed compiling + linking with object files
4925 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4928 added --disable-pic16-port
4929 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4930 * src/SDCCmain.c: linkOptions is changed to set *,
4931 added if/endif conditional macros to remove options help
4932 messages from optionsTable when a port is not configured, added
4933 support for the PIc16 port in the ports table, when executing
4934 the compiler with no port specified on command line, a default
4935 port is selected with the new macro DEFAULT_PORT which is
4936 defined in port.h, in setDefaultOptions() linkOptions is removed
4937 from initialization assignment, since now it is a set,
4938 parseCmdLine uses setParseWithComma for linkOptions, in
4939 linkEdit() linkOptions are accessed with new function indexSet()
4940 which returns the i'th item of a set variable. See SDCCset.c, in
4941 linkEdit() when calling buildCmdLine(), added linkOptions as
4942 last argument. Now users can pass arguments to gplink via the
4943 -Wl option, main() uses pic16glue() to glue up pic16 programs

4955 * src/pic16/glue.c: commented out some error producing lines
4956 * src/pic16/main.c: __config directives are commented out to stop
4957 gpasm complaining and test the linkage with gplink, _linkCmd and
4958 _asmCmd changed to be more gplink and gpasm friendly
4959 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4960 produced an error when parsed, peep rule 12 is added to utilize
4961 movff, but it is commented out since the pCode does not support
4962 yet a command with 2 address arguments
4964 2003-05-18 <johan AT balder>
4966 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4967 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4991 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4993 2003-05-11 Borut Razem <borut.razem AT siol.net>
4995 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4996 the path of bin directory, so that PATH is the only env. variable, which has to be set
4997 in case of standard installation.
4998 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6027 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6029 * in \sdcc\as\mcs51\ changed these files in order to create an
6030 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6031 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6032 following files to include the previous two files: aslink.dsp,
6033 Makefile.aslink, Makefile.bcc, and Makefile.in.
6035 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6036 .adb instead of .cdb
6038 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6040 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6041 value from option --iram-size.
6043 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6045 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6048 2002-09-18 <wiml AT hhhh.org>
6050 * SDCClrange.h: exposed setFromRange() and setToRange()
6051 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6052 packRegsForAccUse() (bug 542397)
6053 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6054 multiple times and emitting the fetch operations more than once
6055 added aopGetUsesAcc() function to allow binary operators to
6056 fetch their operands in the correct order; made genMinus() emit
6057 compact code for X = LITERAL - Y
6059 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6060 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6061 sprintf() in line 1267.
6063 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6064 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6067 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6068 Changes to aslink (All the changes are marked with 'JCF'):
6070 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6073 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6074 area BSEG. Also moves, if possible, the DATA area down into the internal
6075 ram so more space is available.
6077 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6080 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6081 not bytes. Function summary() which creates a memory usage summary
6082 file with extension .mem. Reports of overlaping stack and small stack
6083 size. If the space for the stack is less than 16 bytes aslink trows a
6086 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6087 the 8051. Option 'y' for memory summary output file.
6089 Changes to sdcc (All the changes are marked with 'JCF'):
6091 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6093 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6094 overlaying area for it (uses RegBankUsed[4]).
6096 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6097 bank zero as used by default. By default aslink locates the stack
6098 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6099 the creation of the .mem file. Delegates the allocation of data area
6100 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6101 the begining of the stack area to aslink.
6103 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6104 glue() in SDCCglue.c creates an area for it.
6106 2002-09-03 Borut Razem <borut.razem AT siol.net>
6107 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6108 sdcc/src/pic/glue.c:
6109 introduced atexit() handler for teporay files removal in case of
6110 errors, assertions, ...
6112 2002-08-29 Borut Razem <borut.razem AT siol.net>
6113 * sdcc/support/cpp2/auto-host_vc_in.h:
6114 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6115 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6116 Maybe there is a similar problem with BORLANDC? It should be checked!
6118 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6119 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6120 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6121 was not executed, and the compiler (cl) launched a warning:
6122 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6124 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6125 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6127 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

6134 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6135 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6136 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6137 - added Release configuration in VS projects
6138 - review of compiler an linker options
6139 - VC .exe files are generated in bin_vc directory, not to interfere
6140 with binaries generated from other projects (cygwin, mingw, bcc ...)
6142 * sdcc/src/yacc.dsp: added
6144 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6145 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6146 and insert the version number definitions from .version
6148 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6150 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6156 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6157 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6159 2002-08-11 Borut Razem <borut.razem AT siol.net>
6160 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6162 2002-08-10 Borut Razem <borut.razem AT siol.net>
6163 * src/SDCCmain.c (main):
6164 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6165 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6166 The consequence was that some temporary files were not removed.
6169 unification of code in functions tempfilename() and tempfile():
6170 function tempnam() is defined in Visual Studio 6.0 and .NET
6172 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6174 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6175 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6176 - removed compiler command line option /WX: Treats all warnings as errors
6177 - update a list of source files, included into the project
6179 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6180 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6181 changed project type to Generic Project so that can be correcly converted to VS.NET project
6183 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6185 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6187 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6189 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6190 added return 0 statements after assert() to make compiler happy
6192 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6193 added newline in the def file to keep MSC compiler satisfied
6195 * sdcc/src/z80/gen.c:
6196 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6197 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6198 - solved MSC error in function aopDump()
6200 * sdcc_vc.h: define PREFIX as "\\sdcc"
6202 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

6254 Initialized the new field char *Processor field to NULL in all ports
6257 Compiler generated registers for interrupt context saving
6258 were not getting allocated.
6260 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6263 Fixed left shift. Will promote the left side of a left shift
6264 if a) left shifting more than size of operand or b) when assigned
6265 to something size > size of left side
6267 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6377 * sdcc/src/SDCCloop.c:
6378 Previous fix was not good. basic blocks that have "break" or "return" are
6379 not really partof a loop , but live ranges used in these blocks should
6380 be live thru the entire loop, so set partOfLoop but don't add them to
6383 2002-02-21 <johan AT FRIJA>
