2778 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2780 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2781 loaded with the linker search paths (-L arguments) and the libraries
2782 to be linked with the current source (-l arguments). Changes
2783 currently will affect only the pic16 port.
2784 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2785 include path the port specific paths and port specific libraries,
2786 * gplink command now contains the $3 argument,
2787 * src/pic16/device.h,
2788 * src/pic16/device.c,: structure PIC_device is made public and
2789 renamed to PIC16_device, the same for variable Pics which is renamed

2802 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2804 Documenting changes from previous commits.
2805 * configure.in (version 1.56),
2806 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2807 when generating output files to configure the pic16 library,
2808 but now I've commented it out, since gputils aren't installed in the
2809 SF compile farm, so library won't compile
2811 * device/lib/Makefile.in (version 1.56): initially I've added in
2812 target 'all' the prerequestive 'model-pic16' so it compiled the
2813 pic16 library, but now I've commented it out for the same reasons
2815 * added targets 'model-pic16' and 'objects-pic16' to compile the
2817 * added target 'port-specific-objects-pic16' to handle the
2818 generated libraries and copy them into the build/ directory
2819 * added target 'clean-intermediate-pic16' to clean intermediate
2820 files into pic16 directory
2821 * in target 'installdirs' added line to create directory pic16 in
2822 the installation path
2824 * device/include/Makefile.in (version 1.11): in target 'install'
2825 added lines to copy all header files to installation path,
2826 * in target 'installdirs' added line create directory for pic16
2827 headers in the installation path

2842 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2843 option so that it actually works. Made it specific to the z80, since
2844 the gbz80 doesn't have these kinds of I/O ports.
2846 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2848 * device/include/z180.h,

2861 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2863 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2864 changed interrupt vector table generation to only emit declared vectors.
2865 * device/include/Makefile.in: added missing backslash
2866 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

2870 Mainly changes to support compilation of the device libraries
2871 * src/pic16/device.c: stack is allocated via symbol and not
2872 via literal number. The symbol is placed in the corresponding
2873 position of the data ram
2874 * (pic16_dump_section): relocatable and absolute uninitialized
2875 data are now emitted in sorted order to reduce section naming,
2876 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2877 weren't marked as being in the access bank,
2879 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2881 Added portion of GNU PIC Library under the directory
2882 device/include/pic16 and device/lib/pic16. These files
2883 contain the declarations of SFRs for the PIC18Fxx2 devices.
2884 The directory is initialized via configure from toplevel.
2886 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2888 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2889 the spilllocations to be compared correctly

2914 all over. Telling LaTeX to be less strict with word spacing
2915 to better keep the right margin. Changed some notes about
2916 maintainance of the ports in section 3.2.1 - is it OK like this?
2918 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2955 UPPER for immediate operands,
2956 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2958 * src/pic16/peeph.def: all peepholes with movff are commented out,
2959 because there is a problem in the pcode peep optimizer,
2960 * src/pic16/ralloc.c: the register allocator can now reuse local

2997 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3000 * src/z80/main.c: added missed needLinkerScript flags (more than
3001 one port structure defined in these file)
3002 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3053 include information about variables allocated to the overlay
3056 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3058 * as/mcs51/lkmain.c: Help about -Y option

3070 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3072 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3073 (default behaviour).
3075 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3077 A python script to validate compiler diagnostic messages. It can be
3078 used to verify that sdcc complains about bad c source code and
3079 gives a good location of the error.
3080 * support/valdiag/Makefile,
3081 * support/valdiag/valdiag.py,
3082 * support/valdiag/tests/*
3084 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3099 Bug reported from Jesus Calvino-Fraga
3101 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3103 * sdcc.spec: updated
3104 * device/include/Makefile.in: don't install CVS directories
3105 * device/lib/Makefile.in: added removal of CVS directories after install

3107 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3108 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3109 * src/ds390/gen.c (genRightShift): fixed bug #870788
3110 * src/SDCCast.c (decorateType): fixed bug #870781
3112 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3114 PIC16 port related changes:
3115 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3116 added variable stackPos,
3118 * gen.c: genCall, assignResultValue: added support for
3119 pushing/retrieving function parameters to/from stack,
3120 genFunction,genEndFunction: setup stack frame for the
3122 genAddrOf: will be changed according to bug 863624
3124 * added files genutils.c and genutils.h which contain gen*
3125 debugged and optimised functions extracted from gen.c
3127 * glue.c: added variable 'externs' which holds extern symbols,
3128 pic16emitRegularMap: is modified to properly handle relocatable
3129 symbols under the new scheme,
3130 pic16createInterruptVect: is modified
3131 pic16printPublics: is modified to emit 'global' assembler directives,
3132 added pic16_printExterns to print extern symbols,
3133 pic16glue: initializes stack/frame pointer in the beginning of
3134 the assembly output. Temporary hack, will be corrected later,
3135 because gplink yet does not support stack and SDCC does not
3136 yet support a type of crt0.o object to create the final binary.
3138 * Removed many lines that contain 8051 legacy code.
3139 * The code is finally placed under a 'code' directive.
3140 * Added port specific options.
3142 * _process_pragma: simplified since now we do not need *special*
3143 include file to define SFR registers. But a separate header
3144 will be needed. This will be developed later.
3145 * _pic16_parseOptions: added, parses port specific options:
3146 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3147 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3148 --preplace-udata-with=
3150 * _pic16_setDefaultOptions: modified to initialize section names,
3151 but hack is temporarly out of order since it needs improvement.
3152 * _pic16_genAssemblerPreamble: configuration words are emitted by
3153 their address instead of their name. This part is incomplete and
3154 supports only the 18Fxx2 devices. Other devices will emit an error
3155 during assembly since they do not contain the same set of config
3157 * _pic16_genIVT: is modified,
3159 * pcode.c: added definitions for some hardware registers that are needed
3161 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3162 All PCI entries are updated. Now LFSR is supported.
3163 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3164 * added pic16_newpCodeOpLit2 to support instructions with
3165 two literal arguments
3166 * pic16_pCode2str: corrected code that emits assembler instructions
3167 with two literal operands and those that have an access bit modifier
3168 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3169 this fixes a bug which caused some labels to be lost, when an
3170 assembler directive was added, i.e. banksel,
3171 * pic16_FixRegisterBanking: improved logic that causes the insertion
3173 * InlineFunction: functions that are called once, are not any more
3174 inlined. This can be a port option in the future,
3176 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3178 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3179 hold the corresponding uninitialized symbols,
3180 * pic16_allocProcessorRegister: registers have explicit marked the
3182 * pic16_allocInternalRegister: registers are explicit marked as
3184 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3185 processing list, so bit registers were lost,
3188 * ralloc.h: added field 'accessBank' and original symbol operand
3189 in register definition,
3190 * removed the field isMapped from register definition,
3192 ** Several functions have been removed from various sources:
3193 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3194 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3195 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3196 pic16_assignRelocatableRegisters
3198 ** others have been introduced:
3199 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3200 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3202 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3204 * support/scripts/inc2h.pl: changed definition of BIT_AT
3205 to emit 'sbit at' instead of 'bit at'. This was a request.
3207 PIC16 port related preliminary changes:
3208 * gen.c: prefixed function popRegFromString with
3209 pic16_ and all references to it corrected
3210 * pcode.c: all pic16_pc_* hardware registers prefixed
3211 with underscore (_),
3212 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3213 * ralloc.c: newReg(): when register is REG_SFR then
3214 set address to rIdx,
3215 pic16_allocProcessorRegister(): marks register wasUsed=0
3216 pic16_writeUsedRegs(): added a call to assign processor
3217 registers via pic16_assignFixedRegisters
3219 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3221 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3222 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3223 variables in unused register banks. Also the SSEG is placed
3224 wherever there is enough space for it, and IDATA can be anywhere
3225 in internal RAM. For now compile using -Wl-Y[stack_size].
3226 The mem file is different for this option as well, since it
3227 makes no sense of talking about DSEG lenght.

4222 and JUMPTABLE iCodes properly now (worked by accident before)
4223 * src/mcs51/gen.c (leftRightUseAcc),
4224 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4225 iCode properly now. Use getSize instead of nRegs since a & b
4226 aren't part of the nRegs tally.
4228 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4230 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
4231 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
4232 before instructions that use the _STATUS register
4234 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
4236 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4237 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4238 fetching of the pointer
4239 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4240 copied from genNearPointerSet()
4241 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4242 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4243 If they pop r0/r1 they must be called in the opposite order than aopOp().
4244 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4245 (resp. --stack-auto), prepared for --xstack
4247 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4251 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4253 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
4254 these ports have their own __sdcc_external_start()
4256 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4258 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4259 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4260 type for bits was changed. It resulted in bit variables becoming
4261 global, which is not permitted in PIC 14 assembly output.
4263 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4265 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4267 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4269 Z80 and MCS51 linkers complaint if a public symbol is defined
4270 in more than one library module:
4274 * as/mcs51/Makefile.in
4276 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4278 A few small changes that speed up the peephole optimizer.
4282 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4284 Try to make the peephole optimizer smarter by maintaining
4285 an association between the assembly source code and the
4286 iCodes that originated them. Put this information to use
4287 with a new peephole rule condition "notVolatile" so that
4288 the rules can be aggressive yet still safe.
4293 * src/mcs51/peeph.def
4295 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4299 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4300 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4301 if the left or right operand symbols have the accuse flag set.
4303 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4305 Changed the type of the result of the ! (NOT) operator to char;
4306 previously it returned the same type as the source. This allows
4307 us to eliminate all the genFloatNot functions (all of its target
4308 implementations were very buggy) since !float can use the same
4311 * src/SDCCicode.c (ast2iCode): ! returns char
4312 * src/mcs51/gen.c (genNot, genNotFloat),
4313 * src/ds390/gen.c (genNot, genNotFloat),
4314 * src/z80/gen.c (genNot, genNotFloat),
4315 * src/pic/gen.c (genNot, genNotFloat),
4316 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
4318 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4320 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4321 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4322 during interrupts. Ensure WSAVE is located at a shared bank address.
4323 2. Fixed page selection in some places
4324 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4325 the registers name strings.
4326 4. Fixed "signed / unsigned compare" compiler warnings.
4327 5. The PIC port manages its own allocation of the general purpose
4328 registers, but makes no attempt to reuse them. As a result when
4329 compiling it soon runs out of general purpose registers. Some
4330 additional code was added to the files pcode.c and device.c to walk
4331 through the function call tree and rename the registers so that they
4341 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4342 genPlus() & genMinus() when the result is the same as left or right

4348 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4350 Made bitfield a distinct type from bit so that bitfields
4351 convert as per ANSI C and bits retain their traditional
4352 boolean style behaviour. Implemented bitfield support in
4360 * src/ds390/gen.c: bit v bitfield split
4361 * src/z80/gen.c: New support for bitfields
4362 * support/regression/tests/bitfields.c: reenabled z80,
4365 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4367 Rules 246.x, 247.x relate to bitfields, the others speed up
4368 access to xdata mapped I/O devices.
4370 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4372 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4374 Cleaned up genPackBits and genUnpackBits and added two helper
4375 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4376 for literal assignments in genPackBits (thanks to Frieder for
4382 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4384 Fixed bug #748310 (pointer to function type mishandled when the
4385 function name is omitted). Also fixed a SIGSEGV when a function
4386 attribute (reentrant, etc) is used on a non-function or on a
4387 function but misplaced before the parameter list.
4389 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4391 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4392 * support/Util/SDCCerr.h,
4393 * support/Util/SDCCerr.c: Added func attr misuse error msg

4414 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4416 Made the constant following the "interrupt" keyword optional. If
4417 omitted, the function will not automatically be given an entry
4418 in the interrupt vector table (similar to #pragma NOIV, but
4419 less syntacticly kludgy). The interrupt number is also now
4420 range checked. Also fixed a bug in the high order bit example
4427 * support/Util/SDCCerr.c
4428 * support/Util/SDCCerr.h
4431 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4434 * src/SDCCicode.c (operandOperation): rewritten some ops
4435 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4436 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4438 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4439 be re-activated by defining REDUCE_LITERALS)
4440 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4441 unsigned, but are signed by default
4442 * src/SDCCval.c (constVal): rearranged
4443 * src/SDCCval.c (valMod): preliminary fix
4444 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4487 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4488 * src/SDCCval.c (valDiv, valMod): fixed signdness
4489 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4490 signedness of modulo, left and right shift

4896 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4897 the regression tests I'm not brave enough to enable 245.b, 245.c
4898 * doc/sdccman.lyx: added latex preamble for hyperref package.
4899 Using pdflatex this will give you a hyperlinked pdf file with
4900 bookmarks. (prepend '%' before /usepackage if this breaks something)

4949 * src/SDCCmain.c: linkOptions is changed to set *,
4950 added if/endif conditional macros to remove options help
4951 messages from optionsTable when a port is not configured, added
4952 support for the PIc16 port in the ports table, when executing
4953 the compiler with no port specified on command line, a default
4954 port is selected with the new macro DEFAULT_PORT which is
4955 defined in port.h, in setDefaultOptions() linkOptions is removed
4956 from initialization assignment, since now it is a set,
4957 parseCmdLine uses setParseWithComma for linkOptions, in
4958 linkEdit() linkOptions are accessed with new function indexSet()
4959 which returns the i'th item of a set variable. See SDCCset.c, in
4960 linkEdit() when calling buildCmdLine(), added linkOptions as
4961 last argument. Now users can pass arguments to gplink via the
4962 -Wl option, main() uses pic16glue() to glue up pic16 programs

4974 * src/pic16/glue.c: commented out some error producing lines
4975 * src/pic16/main.c: __config directives are commented out to stop
4976 gpasm complaining and test the linkage with gplink, _linkCmd and
4977 _asmCmd changed to be more gplink and gpasm friendly
4978 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4979 produced an error when parsed, peep rule 12 is added to utilize
4980 movff, but it is commented out since the pCode does not support
4981 yet a command with 2 address arguments
4983 2003-05-18 <johan AT balder>
4985 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5012 2003-05-11 Borut Razem <borut.razem AT siol.net>
5014 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5015 the path of bin directory, so that PATH is the only env. variable, which has to be set
5016 in case of standard installation.

6046 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6048 * in \sdcc\as\mcs51\ changed these files in order to create an
6049 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6050 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6051 following files to include the previous two files: aslink.dsp,
6052 Makefile.aslink, Makefile.bcc, and Makefile.in.
6054 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6055 .adb instead of .cdb
6057 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6059 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6060 value from option --iram-size.
6062 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6064 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6067 2002-09-18 <wiml AT hhhh.org>
6069 * SDCClrange.h: exposed setFromRange() and setToRange()
6070 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6071 packRegsForAccUse() (bug 542397)
6072 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6073 multiple times and emitting the fetch operations more than once
6074 added aopGetUsesAcc() function to allow binary operators to
6075 fetch their operands in the correct order; made genMinus() emit
6076 compact code for X = LITERAL - Y
6078 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6079 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6080 sprintf() in line 1267.
6082 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6083 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6086 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6087 Changes to aslink (All the changes are marked with 'JCF'):
6089 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6092 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6093 area BSEG. Also moves, if possible, the DATA area down into the internal
6094 ram so more space is available.
6096 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6099 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6100 not bytes. Function summary() which creates a memory usage summary
6101 file with extension .mem. Reports of overlaping stack and small stack
6102 size. If the space for the stack is less than 16 bytes aslink trows a
6105 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6106 the 8051. Option 'y' for memory summary output file.
6108 Changes to sdcc (All the changes are marked with 'JCF'):
6110 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6112 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6113 overlaying area for it (uses RegBankUsed[4]).
6115 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6116 bank zero as used by default. By default aslink locates the stack
6117 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6118 the creation of the .mem file. Delegates the allocation of data area
6119 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6120 the begining of the stack area to aslink.
6122 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6123 glue() in SDCCglue.c creates an area for it.
6125 2002-09-03 Borut Razem <borut.razem AT siol.net>
6126 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6127 sdcc/src/pic/glue.c:
6128 introduced atexit() handler for teporay files removal in case of
6129 errors, assertions, ...
6131 2002-08-29 Borut Razem <borut.razem AT siol.net>
6132 * sdcc/support/cpp2/auto-host_vc_in.h:
6133 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6134 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6135 Maybe there is a similar problem with BORLANDC? It should be checked!
6137 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6138 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6139 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6140 was not executed, and the compiler (cl) launched a warning:
6141 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6143 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6151 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6152 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6153 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6154 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6155 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6156 - added Release configuration in VS projects
6157 - review of compiler an linker options
6158 - VC .exe files are generated in bin_vc directory, not to interfere
6159 with binaries generated from other projects (cygwin, mingw, bcc ...)
6161 * sdcc/src/yacc.dsp: added
6163 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6164 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6165 and insert the version number definitions from .version
6167 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6169 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6181 2002-08-10 Borut Razem <borut.razem AT siol.net>
6182 * src/SDCCmain.c (main):
6183 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6184 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6185 The consequence was that some temporary files were not removed.
6188 unification of code in functions tempfilename() and tempfile():
6189 function tempnam() is defined in Visual Studio 6.0 and .NET
6191 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6193 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6194 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

6209 added return 0 statements after assert() to make compiler happy
6211 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6212 added newline in the def file to keep MSC compiler satisfied
6214 * sdcc/src/z80/gen.c:
6215 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6216 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6217 - solved MSC error in function aopDump()
6219 * sdcc_vc.h: define PREFIX as "\\sdcc"

6277 were not getting allocated.
6279 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6282 Fixed left shift. Will promote the left side of a left shift
6283 if a) left shifting more than size of operand or b) when assigned
6284 to something size > size of left side
6286 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6396 * sdcc/src/SDCCloop.c:
6397 Previous fix was not good. basic blocks that have "break" or "return" are
6398 not really partof a loop , but live ranges used in these blocks should
6399 be live thru the entire loop, so set partOfLoop but don't add them to
6402 2002-02-21 <johan AT FRIJA>
