2736 * src/pic/ralloc.h: applied patch from Slade Rich;
2737 added support for multiple code pages and multiple RAM banks on the
2738 PIC 14 port. The ASM files now no longer simply assume all the
2739 code / RAM are in the same page / bank. This means the linker can
2740 safely allocate code/RAM of separate ASM files to different pages/banks.
2741 * doc/sdccman.lyx: added Slade's tips
2742 * src/mcs51/peeph.def: fixed bug #880768

2751 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
2754 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2755 strtof is not part of C89 and isn't included with Mac OS X.
2757 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2759 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
2760 shiftL2Left2Result): fixed bug #879326
2761 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

2784 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2786 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2787 loaded with the linker search paths (-L arguments) and the libraries
2788 to be linked with the current source (-l arguments). Changes
2789 currently will affect only the pic16 port.
2790 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2791 include path the port specific paths and port specific libraries,
2792 * gplink command now contains the $3 argument,
2793 * src/pic16/device.h,
2794 * src/pic16/device.c,: structure PIC_device is made public and
2795 renamed to PIC16_device, the same for variable Pics which is renamed
2796 to Pics16. Updated all references to them.
2797 * src/pic16/glue.c (pic16glue): corrected bug with code
2798 initialization which bypassed the variable initializations block.
2800 * device/lib/pic16/Makefile.rules: removed --penable-stack from
2801 COMPILE_FLAGS and added the --nostdinc option
2803 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2808 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2810 Documenting changes from previous commits.
2811 * configure.in (version 1.56),
2812 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2813 when generating output files to configure the pic16 library,
2814 but now I've commented it out, since gputils aren't installed in the
2815 SF compile farm, so library won't compile
2817 * device/lib/Makefile.in (version 1.56): initially I've added in
2818 target 'all' the prerequestive 'model-pic16' so it compiled the
2819 pic16 library, but now I've commented it out for the same reasons
2821 * added targets 'model-pic16' and 'objects-pic16' to compile the
2823 * added target 'port-specific-objects-pic16' to handle the
2824 generated libraries and copy them into the build/ directory
2825 * added target 'clean-intermediate-pic16' to clean intermediate
2826 files into pic16 directory
2827 * in target 'installdirs' added line to create directory pic16 in
2828 the installation path
2830 * device/include/Makefile.in (version 1.11): in target 'install'
2831 added lines to copy all header files to installation path,
2832 * in target 'installdirs' added line create directory for pic16
2833 headers in the installation path

2848 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2849 option so that it actually works. Made it specific to the z80, since
2850 the gbz80 doesn't have these kinds of I/O ports.
2852 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2854 * device/include/z180.h,

2867 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2869 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2870 changed interrupt vector table generation to only emit declared vectors.

2876 Mainly changes to support compilation of the device libraries
2877 * src/pic16/device.c: stack is allocated via symbol and not
2878 via literal number. The symbol is placed in the corresponding
2879 position of the data ram
2880 * (pic16_dump_section): relocatable and absolute uninitialized
2881 data are now emitted in sorted order to reduce section naming,
2882 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2883 weren't marked as being in the access bank,
2885 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2887 Added portion of GNU PIC Library under the directory
2888 device/include/pic16 and device/lib/pic16. These files
2889 contain the declarations of SFRs for the PIC18Fxx2 devices.
2890 The directory is initialized via configure from toplevel.
2892 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2894 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

2920 all over. Telling LaTeX to be less strict with word spacing
2921 to better keep the right margin. Changed some notes about
2922 maintainance of the ports in section 3.2.1 - is it OK like this?
2924 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2962 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2964 * src/pic16/peeph.def: all peepholes with movff are commented out,
2965 because there is a problem in the pcode peep optimizer,
2966 * src/pic16/ralloc.c: the register allocator can now reuse local

3081 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3083 A python script to validate compiler diagnostic messages. It can be
3084 used to verify that sdcc complains about bad c source code and
3085 gives a good location of the error.
3086 * support/valdiag/Makefile,
3087 * support/valdiag/valdiag.py,
3088 * support/valdiag/tests/*
3090 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3118 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3120 PIC16 port related changes:
3121 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3122 added variable stackPos,
3124 * gen.c: genCall, assignResultValue: added support for
3125 pushing/retrieving function parameters to/from stack,
3126 genFunction,genEndFunction: setup stack frame for the
3128 genAddrOf: will be changed according to bug 863624
3130 * added files genutils.c and genutils.h which contain gen*
3131 debugged and optimised functions extracted from gen.c
3133 * glue.c: added variable 'externs' which holds extern symbols,
3134 pic16emitRegularMap: is modified to properly handle relocatable
3135 symbols under the new scheme,
3136 pic16createInterruptVect: is modified
3137 pic16printPublics: is modified to emit 'global' assembler directives,
3138 added pic16_printExterns to print extern symbols,
3139 pic16glue: initializes stack/frame pointer in the beginning of
3140 the assembly output. Temporary hack, will be corrected later,
3141 because gplink yet does not support stack and SDCC does not
3142 yet support a type of crt0.o object to create the final binary.
3144 * Removed many lines that contain 8051 legacy code.
3145 * The code is finally placed under a 'code' directive.
3146 * Added port specific options.
3148 * _process_pragma: simplified since now we do not need *special*
3149 include file to define SFR registers. But a separate header
3150 will be needed. This will be developed later.
3151 * _pic16_parseOptions: added, parses port specific options:
3152 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3153 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3154 --preplace-udata-with=
3156 * _pic16_setDefaultOptions: modified to initialize section names,
3157 but hack is temporarly out of order since it needs improvement.
3158 * _pic16_genAssemblerPreamble: configuration words are emitted by
3159 their address instead of their name. This part is incomplete and
3160 supports only the 18Fxx2 devices. Other devices will emit an error
3161 during assembly since they do not contain the same set of config
3163 * _pic16_genIVT: is modified,
3165 * pcode.c: added definitions for some hardware registers that are needed
3167 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3168 All PCI entries are updated. Now LFSR is supported.
3169 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3170 * added pic16_newpCodeOpLit2 to support instructions with
3171 two literal arguments
3172 * pic16_pCode2str: corrected code that emits assembler instructions
3173 with two literal operands and those that have an access bit modifier
3174 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3175 this fixes a bug which caused some labels to be lost, when an
3176 assembler directive was added, i.e. banksel,
3177 * pic16_FixRegisterBanking: improved logic that causes the insertion
3179 * InlineFunction: functions that are called once, are not any more
3180 inlined. This can be a port option in the future,
3182 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3184 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3185 hold the corresponding uninitialized symbols,
3186 * pic16_allocProcessorRegister: registers have explicit marked the
3188 * pic16_allocInternalRegister: registers are explicit marked as
3190 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3191 processing list, so bit registers were lost,
3194 * ralloc.h: added field 'accessBank' and original symbol operand
3195 in register definition,
3196 * removed the field isMapped from register definition,
3198 ** Several functions have been removed from various sources:
3199 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3200 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3201 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3202 pic16_assignRelocatableRegisters
3204 ** others have been introduced:
3205 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3206 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3208 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3210 * support/scripts/inc2h.pl: changed definition of BIT_AT
3211 to emit 'sbit at' instead of 'bit at'. This was a request.
3213 PIC16 port related preliminary changes:
3214 * gen.c: prefixed function popRegFromString with
3215 pic16_ and all references to it corrected
3216 * pcode.c: all pic16_pc_* hardware registers prefixed
3217 with underscore (_),
3218 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3219 * ralloc.c: newReg(): when register is REG_SFR then
3220 set address to rIdx,
3221 pic16_allocProcessorRegister(): marks register wasUsed=0
3222 pic16_writeUsedRegs(): added a call to assign processor
3223 registers via pic16_assignFixedRegisters
3225 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3227 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3228 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3229 variables in unused register banks. Also the SSEG is placed
3230 wherever there is enough space for it, and IDATA can be anywhere
3231 in internal RAM. For now compile using -Wl-Y[stack_size].
3232 The mem file is different for this option as well, since it
3233 makes no sense of talking about DSEG lenght.
3235 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3237 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4228 and JUMPTABLE iCodes properly now (worked by accident before)
4229 * src/mcs51/gen.c (leftRightUseAcc),
4230 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4231 iCode properly now. Use getSize instead of nRegs since a & b
4232 aren't part of the nRegs tally.
4234 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4236 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

4242 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4243 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4244 fetching of the pointer
4245 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4246 copied from genNearPointerSet()
4247 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4248 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4249 If they pop r0/r1 they must be called in the opposite order than aopOp().
4250 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4251 (resp. --stack-auto), prepared for --xstack

4262 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4264 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4265 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4266 type for bits was changed. It resulted in bit variables becoming
4267 global, which is not permitted in PIC 14 assembly output.
4269 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4271 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4284 A few small changes that speed up the peephole optimizer.
4288 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4290 Try to make the peephole optimizer smarter by maintaining
4291 an association between the assembly source code and the
4292 iCodes that originated them. Put this information to use
4293 with a new peephole rule condition "notVolatile" so that
4294 the rules can be aggressive yet still safe.
4299 * src/mcs51/peeph.def
4301 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4305 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4306 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4307 if the left or right operand symbols have the accuse flag set.
4309 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4311 Changed the type of the result of the ! (NOT) operator to char;
4312 previously it returned the same type as the source. This allows
4313 us to eliminate all the genFloatNot functions (all of its target
4314 implementations were very buggy) since !float can use the same
4317 * src/SDCCicode.c (ast2iCode): ! returns char

4326 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4327 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4328 during interrupts. Ensure WSAVE is located at a shared bank address.
4329 2. Fixed page selection in some places
4330 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4331 the registers name strings.
4332 4. Fixed "signed / unsigned compare" compiler warnings.
4333 5. The PIC port manages its own allocation of the general purpose
4334 registers, but makes no attempt to reuse them. As a result when
4335 compiling it soon runs out of general purpose registers. Some
4336 additional code was added to the files pcode.c and device.c to walk
4337 through the function call tree and rename the registers so that they
4347 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4348 genPlus() & genMinus() when the result is the same as left or right

4354 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4356 Made bitfield a distinct type from bit so that bitfields
4357 convert as per ANSI C and bits retain their traditional
4358 boolean style behaviour. Implemented bitfield support in
4366 * src/ds390/gen.c: bit v bitfield split
4367 * src/z80/gen.c: New support for bitfields
4368 * support/regression/tests/bitfields.c: reenabled z80,
4371 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4373 Rules 246.x, 247.x relate to bitfields, the others speed up
4374 access to xdata mapped I/O devices.
4376 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4378 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4380 Cleaned up genPackBits and genUnpackBits and added two helper
4381 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4382 for literal assignments in genPackBits (thanks to Frieder for
4388 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4390 Fixed bug #748310 (pointer to function type mishandled when the
4391 function name is omitted). Also fixed a SIGSEGV when a function
4392 attribute (reentrant, etc) is used on a non-function or on a
4393 function but misplaced before the parameter list.
4395 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4397 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4398 * support/Util/SDCCerr.h,

4420 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4422 Made the constant following the "interrupt" keyword optional. If
4423 omitted, the function will not automatically be given an entry
4424 in the interrupt vector table (similar to #pragma NOIV, but
4425 less syntacticly kludgy). The interrupt number is also now
4426 range checked. Also fixed a bug in the high order bit example

4440 * src/SDCCicode.c (operandOperation): rewritten some ops
4441 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4442 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4444 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4445 be re-activated by defining REDUCE_LITERALS)
4446 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4447 unsigned, but are signed by default
4448 * src/SDCCval.c (constVal): rearranged
4449 * src/SDCCval.c (valMod): preliminary fix
4450 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4902 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4903 the regression tests I'm not brave enough to enable 245.b, 245.c
4904 * doc/sdccman.lyx: added latex preamble for hyperref package.
4905 Using pdflatex this will give you a hyperlinked pdf file with
4906 bookmarks. (prepend '%' before /usepackage if this breaks something)

4942 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
4944 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4946 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4947 it can be defined with CFLAGS when running configure
4948 * src/SDCCmain.c: fixed compiling + linking with object files
4950 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4952 * configure.in: configure for pic16 port,
4953 added --disable-pic16-port
4954 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4955 * src/SDCCmain.c: linkOptions is changed to set *,
4956 added if/endif conditional macros to remove options help
4957 messages from optionsTable when a port is not configured, added
4958 support for the PIc16 port in the ports table, when executing
4959 the compiler with no port specified on command line, a default
4960 port is selected with the new macro DEFAULT_PORT which is
4961 defined in port.h, in setDefaultOptions() linkOptions is removed
4962 from initialization assignment, since now it is a set,
4963 parseCmdLine uses setParseWithComma for linkOptions, in
4964 linkEdit() linkOptions are accessed with new function indexSet()
4965 which returns the i'th item of a set variable. See SDCCset.c, in
4966 linkEdit() when calling buildCmdLine(), added linkOptions as
4967 last argument. Now users can pass arguments to gplink via the
4968 -Wl option, main() uses pic16glue() to glue up pic16 programs
4969 * src/SDCCpeeph.c: various changes to support pic16

4976 added macro DEFAULT_PORT
4977 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
4978 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4980 * src/pic16/glue.c: commented out some error producing lines
4981 * src/pic16/main.c: __config directives are commented out to stop
4982 gpasm complaining and test the linkage with gplink, _linkCmd and
4983 _asmCmd changed to be more gplink and gpasm friendly
4984 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4985 produced an error when parsed, peep rule 12 is added to utilize
4986 movff, but it is commented out since the pCode does not support
4987 yet a command with 2 address arguments
4989 2003-05-18 <johan AT balder>
4991 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4992 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5018 2003-05-11 Borut Razem <borut.razem AT siol.net>
5020 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5021 the path of bin directory, so that PATH is the only env. variable, which has to be set
5022 in case of standard installation.
5023 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6055 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6056 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6057 following files to include the previous two files: aslink.dsp,
6058 Makefile.aslink, Makefile.bcc, and Makefile.in.
6060 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6061 .adb instead of .cdb
6063 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6065 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6066 value from option --iram-size.
6068 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6070 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6073 2002-09-18 <wiml AT hhhh.org>
6075 * SDCClrange.h: exposed setFromRange() and setToRange()
6076 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6077 packRegsForAccUse() (bug 542397)
6078 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6079 multiple times and emitting the fetch operations more than once
6080 added aopGetUsesAcc() function to allow binary operators to
6081 fetch their operands in the correct order; made genMinus() emit
6082 compact code for X = LITERAL - Y
6084 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6085 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6086 sprintf() in line 1267.
6088 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6089 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6092 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6093 Changes to aslink (All the changes are marked with 'JCF'):
6095 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6098 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6099 area BSEG. Also moves, if possible, the DATA area down into the internal
6100 ram so more space is available.
6102 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6105 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6106 not bytes. Function summary() which creates a memory usage summary
6107 file with extension .mem. Reports of overlaping stack and small stack
6108 size. If the space for the stack is less than 16 bytes aslink trows a
6111 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6112 the 8051. Option 'y' for memory summary output file.
6114 Changes to sdcc (All the changes are marked with 'JCF'):
6116 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6118 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6119 overlaying area for it (uses RegBankUsed[4]).
6121 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6122 bank zero as used by default. By default aslink locates the stack
6123 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6124 the creation of the .mem file. Delegates the allocation of data area
6125 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6126 the begining of the stack area to aslink.
6128 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6129 glue() in SDCCglue.c creates an area for it.
6131 2002-09-03 Borut Razem <borut.razem AT siol.net>
6132 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6133 sdcc/src/pic/glue.c:
6134 introduced atexit() handler for teporay files removal in case of
6135 errors, assertions, ...
6137 2002-08-29 Borut Razem <borut.razem AT siol.net>
6138 * sdcc/support/cpp2/auto-host_vc_in.h:
6139 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6140 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6141 Maybe there is a similar problem with BORLANDC? It should be checked!
6143 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6144 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6145 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6146 was not executed, and the compiler (cl) launched a warning:
6147 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6149 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6150 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6152 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6153 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6155 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6156 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6157 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6158 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6159 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6160 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6161 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6162 - added Release configuration in VS projects
6163 - review of compiler an linker options
6164 - VC .exe files are generated in bin_vc directory, not to interfere
6165 with binaries generated from other projects (cygwin, mingw, bcc ...)
6167 * sdcc/src/yacc.dsp: added
6169 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6170 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6171 and insert the version number definitions from .version
6173 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6175 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6176 added - genarate auto-host.h using auto-host_vc_in.h as template
6179 removed from CVS, generated automatically

6184 2002-08-11 Borut Razem <borut.razem AT siol.net>
6185 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6187 2002-08-10 Borut Razem <borut.razem AT siol.net>
6188 * src/SDCCmain.c (main):
6189 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6190 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6191 The consequence was that some temporary files were not removed.
6194 unification of code in functions tempfilename() and tempfile():
6195 function tempnam() is defined in Visual Studio 6.0 and .NET
6197 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6199 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6200 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6201 - removed compiler command line option /WX: Treats all warnings as errors
6202 - update a list of source files, included into the project
6204 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6205 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6206 changed project type to Generic Project so that can be correcly converted to VS.NET project
6208 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6210 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6212 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6214 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6215 added return 0 statements after assert() to make compiler happy
6217 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6218 added newline in the def file to keep MSC compiler satisfied
6220 * sdcc/src/z80/gen.c:
6221 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6222 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6223 - solved MSC error in function aopDump()
6225 * sdcc_vc.h: define PREFIX as "\\sdcc"
6227 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6228 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6276 Added -p option. Allows port dependent processor to be specified.
6279 Initialized the new field char *Processor field to NULL in all ports
6282 Compiler generated registers for interrupt context saving
6283 were not getting allocated.
6285 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6288 Fixed left shift. Will promote the left side of a left shift
6289 if a) left shifting more than size of operand or b) when assigned
6290 to something size > size of left side
6292 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6400 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6402 * sdcc/src/SDCCloop.c:
6403 Previous fix was not good. basic blocks that have "break" or "return" are
6404 not really partof a loop , but live ranges used in these blocks should
6405 be live thru the entire loop, so set partOfLoop but don't add them to
6408 2002-02-21 <johan AT FRIJA>
6410 * src/SDCCcse.c: fixed bug #514308
6412 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6418 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6420 2002-02-10 Karl Bongers <karl AT turbobit.com>

6431 for use as a multiple module SDCDB test case.
6433 * sim/ucsim/cmd.src/cmdset.cc:
6434 Took out debug printfs in ucsim "next" command.
6437 Karl and Johan start ucsim XA support. Most dissassembly working,
6438 about 75% emulation done(plenty of work remaining).
6440 * sim/ucsim/z80.src:
6441 Add Z80 support to ucsim, add test-ucz80 regression test,
6442 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
