2773 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2775 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2776 loaded with the linker search paths (-L arguments) and the libraries
2777 to be linked with the current source (-l arguments). Changes
2778 currently will affect only the pic16 port.
2779 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2780 include path the port specific paths and port specific libraries,
2781 * gplink command now contains the $3 argument,
2782 * src/pic16/device.h,
2783 * src/pic16/device.c,: structure PIC_device is made public and
2784 renamed to PIC16_device, the same for variable Pics which is renamed
2785 to Pics16. Updated all references to them.
2786 * src/pic16/glue.c (pic16glue): corrected bug with code
2787 initialization which bypassed the variable initializations block.

2797 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2799 Documenting changes from previous commits.
2800 * configure.in (version 1.56),
2801 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2802 when generating output files to configure the pic16 library,
2803 but now I've commented it out, since gputils aren't installed in the
2804 SF compile farm, so library won't compile
2806 * device/lib/Makefile.in (version 1.56): initially I've added in
2807 target 'all' the prerequestive 'model-pic16' so it compiled the
2808 pic16 library, but now I've commented it out for the same reasons
2810 * added targets 'model-pic16' and 'objects-pic16' to compile the
2812 * added target 'port-specific-objects-pic16' to handle the
2813 generated libraries and copy them into the build/ directory
2814 * added target 'clean-intermediate-pic16' to clean intermediate
2815 files into pic16 directory
2816 * in target 'installdirs' added line to create directory pic16 in
2817 the installation path
2819 * device/include/Makefile.in (version 1.11): in target 'install'
2820 added lines to copy all header files to installation path,
2821 * in target 'installdirs' added line create directory for pic16
2822 headers in the installation path

2837 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2838 option so that it actually works. Made it specific to the z80, since
2839 the gbz80 doesn't have these kinds of I/O ports.
2841 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2843 * device/include/z180.h,

2856 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2858 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2859 changed interrupt vector table generation to only emit declared vectors.
2860 * device/include/Makefile.in: added missing backslash
2861 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
2863 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2865 Mainly changes to support compilation of the device libraries
2866 * src/pic16/device.c: stack is allocated via symbol and not
2867 via literal number. The symbol is placed in the corresponding
2868 position of the data ram
2869 * (pic16_dump_section): relocatable and absolute uninitialized
2870 data are now emitted in sorted order to reduce section naming,
2871 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2872 weren't marked as being in the access bank,
2874 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2876 Added portion of GNU PIC Library under the directory
2877 device/include/pic16 and device/lib/pic16. These files
2878 contain the declarations of SFRs for the PIC18Fxx2 devices.
2879 The directory is initialized via configure from toplevel.
2881 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2883 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2884 the spilllocations to be compared correctly
2886 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2888 * src/SDCCast.c (decorateType): fixed bug introduced today
2890 2004-01-12 Borut Razem <borut.razem AT siol.net>
2892 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2908 * doc/sdccman.lyx: Moved and added some sections, small changes
2909 all over. Telling LaTeX to be less strict with word spacing
2910 to better keep the right margin. Changed some notes about
2911 maintainance of the ports in section 3.2.1 - is it OK like this?
2913 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2949 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
2950 UPPER for immediate operands,
2951 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2953 * src/pic16/peeph.def: all peepholes with movff are commented out,
2954 because there is a problem in the pcode peep optimizer,
2955 * src/pic16/ralloc.c: the register allocator can now reuse local
2956 function symbols for another function. This saves register usage.
2957 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2959 Added file src/pic16/NOTES with information about program writing on
2960 the current port version.

2992 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2995 * src/z80/main.c: added missed needLinkerScript flags (more than
2996 one port structure defined in these file)
2997 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3013 needLinkerScript flag
3015 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3016 * src/pic/glue.c: added variable udata_section_name to
3017 override default uninitialized data segment definition for
3018 devices only with SHAREBANK memory (reported from Erik Epetrich)
3019 * (pic14emitOverlay): modified to emit a commented overlay segment
3020 directive when no overlay data exist
3021 * (picglue): modified to emit uninitialized data segment
3022 according to udata_section_name

3027 arguments via -W option
3028 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3029 object file from '.rel' to '.o' in port->linker structure,
3030 changed size of fptr from 2 to 3 in port structure
3032 2004-01-07 Borut Razem <borut.razem AT siol.net>
3034 * support/scripts/sdcc.nsi: update PATH
3035 * support/scripts/sdcc.ico: craeted
3037 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3048 include information about variables allocated to the overlay
3051 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3053 * as/mcs51/lkmain.c: Help about -Y option

3065 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3067 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3068 (default behaviour).
3070 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3072 A python script to validate compiler diagnostic messages. It can be
3073 used to verify that sdcc complains about bad c source code and
3074 gives a good location of the error.
3075 * support/valdiag/Makefile,
3076 * support/valdiag/valdiag.py,
3077 * support/valdiag/tests/*
3079 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3081 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3092 * src/common.h: added ifndef/define/endif macros
3093 around the header file.
3094 Bug reported from Jesus Calvino-Fraga
3096 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3098 * sdcc.spec: updated
3099 * device/include/Makefile.in: don't install CVS directories
3100 * device/lib/Makefile.in: added removal of CVS directories after install
3101 * doc/Makefile: fixed install, added local_icons
3102 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3103 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3104 * src/ds390/gen.c (genRightShift): fixed bug #870788
3105 * src/SDCCast.c (decorateType): fixed bug #870781
3107 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3109 PIC16 port related changes:
3110 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3111 added variable stackPos,
3113 * gen.c: genCall, assignResultValue: added support for
3114 pushing/retrieving function parameters to/from stack,
3115 genFunction,genEndFunction: setup stack frame for the
3117 genAddrOf: will be changed according to bug 863624
3119 * added files genutils.c and genutils.h which contain gen*
3120 debugged and optimised functions extracted from gen.c
3122 * glue.c: added variable 'externs' which holds extern symbols,
3123 pic16emitRegularMap: is modified to properly handle relocatable
3124 symbols under the new scheme,
3125 pic16createInterruptVect: is modified
3126 pic16printPublics: is modified to emit 'global' assembler directives,
3127 added pic16_printExterns to print extern symbols,
3128 pic16glue: initializes stack/frame pointer in the beginning of
3129 the assembly output. Temporary hack, will be corrected later,
3130 because gplink yet does not support stack and SDCC does not
3131 yet support a type of crt0.o object to create the final binary.
3133 * Removed many lines that contain 8051 legacy code.
3134 * The code is finally placed under a 'code' directive.
3135 * Added port specific options.
3137 * _process_pragma: simplified since now we do not need *special*
3138 include file to define SFR registers. But a separate header
3139 will be needed. This will be developed later.
3140 * _pic16_parseOptions: added, parses port specific options:
3141 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3142 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3143 --preplace-udata-with=
3145 * _pic16_setDefaultOptions: modified to initialize section names,
3146 but hack is temporarly out of order since it needs improvement.
3147 * _pic16_genAssemblerPreamble: configuration words are emitted by
3148 their address instead of their name. This part is incomplete and
3149 supports only the 18Fxx2 devices. Other devices will emit an error
3150 during assembly since they do not contain the same set of config
3152 * _pic16_genIVT: is modified,
3154 * pcode.c: added definitions for some hardware registers that are needed
3156 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3157 All PCI entries are updated. Now LFSR is supported.
3158 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3159 * added pic16_newpCodeOpLit2 to support instructions with
3160 two literal arguments
3161 * pic16_pCode2str: corrected code that emits assembler instructions
3162 with two literal operands and those that have an access bit modifier
3163 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3164 this fixes a bug which caused some labels to be lost, when an
3165 assembler directive was added, i.e. banksel,
3166 * pic16_FixRegisterBanking: improved logic that causes the insertion
3168 * InlineFunction: functions that are called once, are not any more
3169 inlined. This can be a port option in the future,
3171 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3173 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3174 hold the corresponding uninitialized symbols,
3175 * pic16_allocProcessorRegister: registers have explicit marked the
3177 * pic16_allocInternalRegister: registers are explicit marked as
3179 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3180 processing list, so bit registers were lost,
3183 * ralloc.h: added field 'accessBank' and original symbol operand
3184 in register definition,
3185 * removed the field isMapped from register definition,
3187 ** Several functions have been removed from various sources:
3188 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3189 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3190 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3191 pic16_assignRelocatableRegisters
3193 ** others have been introduced:
3194 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3195 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3197 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3199 * support/scripts/inc2h.pl: changed definition of BIT_AT
3200 to emit 'sbit at' instead of 'bit at'. This was a request.
3202 PIC16 port related preliminary changes:
3203 * gen.c: prefixed function popRegFromString with
3204 pic16_ and all references to it corrected
3205 * pcode.c: all pic16_pc_* hardware registers prefixed
3206 with underscore (_),
3207 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3208 * ralloc.c: newReg(): when register is REG_SFR then
3209 set address to rIdx,
3210 pic16_allocProcessorRegister(): marks register wasUsed=0
3211 pic16_writeUsedRegs(): added a call to assign processor
3212 registers via pic16_assignFixedRegisters
3214 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3216 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3217 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3218 variables in unused register banks. Also the SSEG is placed
3219 wherever there is enough space for it, and IDATA can be anywhere
3220 in internal RAM. For now compile using -Wl-Y[stack_size].
3221 The mem file is different for this option as well, since it
3222 makes no sense of talking about DSEG lenght.

4217 and JUMPTABLE iCodes properly now (worked by accident before)
4218 * src/mcs51/gen.c (leftRightUseAcc),
4219 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4220 iCode properly now. Use getSize instead of nRegs since a & b
4221 aren't part of the nRegs tally.
4223 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4225 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
4226 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
4227 before instructions that use the _STATUS register
4229 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
4231 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4232 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4233 fetching of the pointer
4234 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4235 copied from genNearPointerSet()
4236 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4237 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4238 If they pop r0/r1 they must be called in the opposite order than aopOp().
4239 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4240 (resp. --stack-auto), prepared for --xstack
4242 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4246 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4248 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
4249 these ports have their own __sdcc_external_start()
4251 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4253 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4254 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4255 type for bits was changed. It resulted in bit variables becoming
4256 global, which is not permitted in PIC 14 assembly output.
4258 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4260 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4262 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4264 Z80 and MCS51 linkers complaint if a public symbol is defined
4265 in more than one library module:

4271 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4273 A few small changes that speed up the peephole optimizer.
4277 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4279 Try to make the peephole optimizer smarter by maintaining
4280 an association between the assembly source code and the
4281 iCodes that originated them. Put this information to use
4282 with a new peephole rule condition "notVolatile" so that
4283 the rules can be aggressive yet still safe.
4288 * src/mcs51/peeph.def
4290 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4294 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4295 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4296 if the left or right operand symbols have the accuse flag set.
4298 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4300 Changed the type of the result of the ! (NOT) operator to char;
4301 previously it returned the same type as the source. This allows
4302 us to eliminate all the genFloatNot functions (all of its target
4303 implementations were very buggy) since !float can use the same
4306 * src/SDCCicode.c (ast2iCode): ! returns char
4307 * src/mcs51/gen.c (genNot, genNotFloat),
4308 * src/ds390/gen.c (genNot, genNotFloat),
4309 * src/z80/gen.c (genNot, genNotFloat),
4310 * src/pic/gen.c (genNot, genNotFloat),
4311 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
4313 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4315 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4316 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4317 during interrupts. Ensure WSAVE is located at a shared bank address.
4318 2. Fixed page selection in some places
4319 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4320 the registers name strings.
4321 4. Fixed "signed / unsigned compare" compiler warnings.
4322 5. The PIC port manages its own allocation of the general purpose
4323 registers, but makes no attempt to reuse them. As a result when
4324 compiling it soon runs out of general purpose registers. Some
4325 additional code was added to the files pcode.c and device.c to walk
4326 through the function call tree and rename the registers so that they
4336 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4337 genPlus() & genMinus() when the result is the same as left or right

4343 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4345 Made bitfield a distinct type from bit so that bitfields
4346 convert as per ANSI C and bits retain their traditional
4347 boolean style behaviour. Implemented bitfield support in
4355 * src/ds390/gen.c: bit v bitfield split
4356 * src/z80/gen.c: New support for bitfields
4357 * support/regression/tests/bitfields.c: reenabled z80,
4360 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4362 Rules 246.x, 247.x relate to bitfields, the others speed up
4363 access to xdata mapped I/O devices.
4365 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4367 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4369 Cleaned up genPackBits and genUnpackBits and added two helper
4370 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4371 for literal assignments in genPackBits (thanks to Frieder for
4377 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4379 Fixed bug #748310 (pointer to function type mishandled when the
4380 function name is omitted). Also fixed a SIGSEGV when a function
4381 attribute (reentrant, etc) is used on a non-function or on a
4382 function but misplaced before the parameter list.
4384 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4386 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4387 * support/Util/SDCCerr.h,
4388 * support/Util/SDCCerr.c: Added func attr misuse error msg

4409 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4411 Made the constant following the "interrupt" keyword optional. If
4412 omitted, the function will not automatically be given an entry
4413 in the interrupt vector table (similar to #pragma NOIV, but
4414 less syntacticly kludgy). The interrupt number is also now
4415 range checked. Also fixed a bug in the high order bit example
4422 * support/Util/SDCCerr.c
4423 * support/Util/SDCCerr.h
4426 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4429 * src/SDCCicode.c (operandOperation): rewritten some ops
4430 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4431 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4433 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4434 be re-activated by defining REDUCE_LITERALS)
4435 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4436 unsigned, but are signed by default
4437 * src/SDCCval.c (constVal): rearranged
4438 * src/SDCCval.c (valMod): preliminary fix
4439 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4482 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4483 * src/SDCCval.c (valDiv, valMod): fixed signdness
4484 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4485 signedness of modulo, left and right shift

4891 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4892 the regression tests I'm not brave enough to enable 245.b, 245.c
4893 * doc/sdccman.lyx: added latex preamble for hyperref package.
4894 Using pdflatex this will give you a hyperlinked pdf file with
4895 bookmarks. (prepend '%' before /usepackage if this breaks something)

4944 * src/SDCCmain.c: linkOptions is changed to set *,
4945 added if/endif conditional macros to remove options help
4946 messages from optionsTable when a port is not configured, added
4947 support for the PIc16 port in the ports table, when executing
4948 the compiler with no port specified on command line, a default
4949 port is selected with the new macro DEFAULT_PORT which is
4950 defined in port.h, in setDefaultOptions() linkOptions is removed
4951 from initialization assignment, since now it is a set,
4952 parseCmdLine uses setParseWithComma for linkOptions, in
4953 linkEdit() linkOptions are accessed with new function indexSet()
4954 which returns the i'th item of a set variable. See SDCCset.c, in
4955 linkEdit() when calling buildCmdLine(), added linkOptions as
4956 last argument. Now users can pass arguments to gplink via the
4957 -Wl option, main() uses pic16glue() to glue up pic16 programs

4969 * src/pic16/glue.c: commented out some error producing lines
4970 * src/pic16/main.c: __config directives are commented out to stop
4971 gpasm complaining and test the linkage with gplink, _linkCmd and
4972 _asmCmd changed to be more gplink and gpasm friendly
4973 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4974 produced an error when parsed, peep rule 12 is added to utilize
4975 movff, but it is commented out since the pCode does not support
4976 yet a command with 2 address arguments
4978 2003-05-18 <johan AT balder>
4980 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5007 2003-05-11 Borut Razem <borut.razem AT siol.net>
5009 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5010 the path of bin directory, so that PATH is the only env. variable, which has to be set
5011 in case of standard installation.

6041 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6043 * in \sdcc\as\mcs51\ changed these files in order to create an
6044 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6045 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6046 following files to include the previous two files: aslink.dsp,
6047 Makefile.aslink, Makefile.bcc, and Makefile.in.
6049 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6050 .adb instead of .cdb
6052 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6054 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6055 value from option --iram-size.
6057 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6059 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6062 2002-09-18 <wiml AT hhhh.org>
6064 * SDCClrange.h: exposed setFromRange() and setToRange()
6065 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6066 packRegsForAccUse() (bug 542397)
6067 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6068 multiple times and emitting the fetch operations more than once
6069 added aopGetUsesAcc() function to allow binary operators to
6070 fetch their operands in the correct order; made genMinus() emit
6071 compact code for X = LITERAL - Y
6073 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6074 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6075 sprintf() in line 1267.
6077 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6078 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6081 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6082 Changes to aslink (All the changes are marked with 'JCF'):
6084 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6087 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6088 area BSEG. Also moves, if possible, the DATA area down into the internal
6089 ram so more space is available.
6091 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6094 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6095 not bytes. Function summary() which creates a memory usage summary
6096 file with extension .mem. Reports of overlaping stack and small stack
6097 size. If the space for the stack is less than 16 bytes aslink trows a
6100 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6101 the 8051. Option 'y' for memory summary output file.
6103 Changes to sdcc (All the changes are marked with 'JCF'):
6105 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6107 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6108 overlaying area for it (uses RegBankUsed[4]).
6110 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6111 bank zero as used by default. By default aslink locates the stack
6112 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6113 the creation of the .mem file. Delegates the allocation of data area
6114 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6115 the begining of the stack area to aslink.
6117 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6118 glue() in SDCCglue.c creates an area for it.
6120 2002-09-03 Borut Razem <borut.razem AT siol.net>
6121 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6122 sdcc/src/pic/glue.c:
6123 introduced atexit() handler for teporay files removal in case of
6124 errors, assertions, ...
6126 2002-08-29 Borut Razem <borut.razem AT siol.net>
6127 * sdcc/support/cpp2/auto-host_vc_in.h:
6128 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6129 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6130 Maybe there is a similar problem with BORLANDC? It should be checked!
6132 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6133 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6134 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6135 was not executed, and the compiler (cl) launched a warning:
6136 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6138 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6146 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6147 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6148 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6149 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6150 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6151 - added Release configuration in VS projects
6152 - review of compiler an linker options
6153 - VC .exe files are generated in bin_vc directory, not to interfere
6154 with binaries generated from other projects (cygwin, mingw, bcc ...)
6156 * sdcc/src/yacc.dsp: added
6158 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6159 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6160 and insert the version number definitions from .version
6162 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6164 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6174 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6176 2002-08-10 Borut Razem <borut.razem AT siol.net>
6177 * src/SDCCmain.c (main):
6178 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6179 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6180 The consequence was that some temporary files were not removed.
6183 unification of code in functions tempfilename() and tempfile():
6184 function tempnam() is defined in Visual Studio 6.0 and .NET
6186 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6188 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6189 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

6203 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6204 added return 0 statements after assert() to make compiler happy
6206 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6207 added newline in the def file to keep MSC compiler satisfied
6209 * sdcc/src/z80/gen.c:
6210 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6211 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6212 - solved MSC error in function aopDump()
6214 * sdcc_vc.h: define PREFIX as "\\sdcc"
6216 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

6268 Initialized the new field char *Processor field to NULL in all ports
6271 Compiler generated registers for interrupt context saving
6272 were not getting allocated.
6274 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6277 Fixed left shift. Will promote the left side of a left shift
6278 if a) left shifting more than size of operand or b) when assigned
6279 to something size > size of left side
6281 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6389 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6391 * sdcc/src/SDCCloop.c:
6392 Previous fix was not good. basic blocks that have "break" or "return" are
6393 not really partof a loop , but live ranges used in these blocks should
6394 be live thru the entire loop, so set partOfLoop but don't add them to
6397 2002-02-21 <johan AT FRIJA>
6399 * src/SDCCcse.c: fixed bug #514308
6401 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6426 Karl and Johan start ucsim XA support. Most dissassembly working,
6427 about 75% emulation done(plenty of work remaining).
6429 * sim/ucsim/z80.src:
6430 Add Z80 support to ucsim, add test-ucz80 regression test,
6431 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
