2728 * src/SDCCast.c: added an additional type flow in decorateType() of
2729 opposite direction, see feature request #860006; it's enabled at runtime
2730 by setting the environment variable SDCC_NEWTYPEFLOW
2731 * src/SDCCast.h: changed prototype of decorateType()
2732 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
2733 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
2734 'char' to 'int' can be omitted, if both operands are 'unsigned char';
2735 see feature request #877103
2736 * src/SDCCval.c: updated call of decorateType()
2737 (valBitwise): fixed bug #882876
2738 (valMinus): added promotion
2739 (valLogicAndOr): result is unsigned
2740 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
2741 * src/SDCCsymt.c (computeType),
2742 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
2743 must not cause an unsigned operation
2744 * src/pic/glue (pic14emitRegularMap),
2745 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
2747 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
2749 * src/pic/pcode.c (PCodeID): commented out left over debug code
2751 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>

2762 * src/pic/pcoderegs.c,
2764 * src/pic/ralloc.h: applied patch from Slade Rich;
2765 added support for multiple code pages and multiple RAM banks on the
2766 PIC 14 port. The ASM files now no longer simply assume all the
2767 code / RAM are in the same page / bank. This means the linker can
2768 safely allocate code/RAM of separate ASM files to different pages/banks.
2769 * doc/sdccman.lyx: added Slade's tips
2770 * src/mcs51/peeph.def: fixed bug #880768

2779 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
2782 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2783 strtof is not part of C89 and isn't included with Mac OS X.
2785 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2787 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

2809 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
2812 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2814 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2815 loaded with the linker search paths (-L arguments) and the libraries
2816 to be linked with the current source (-l arguments). Changes
2817 currently will affect only the pic16 port.
2818 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2819 include path the port specific paths and port specific libraries,
2820 * gplink command now contains the $3 argument,
2821 * src/pic16/device.h,
2822 * src/pic16/device.c,: structure PIC_device is made public and
2823 renamed to PIC16_device, the same for variable Pics which is renamed
2824 to Pics16. Updated all references to them.
2825 * src/pic16/glue.c (pic16glue): corrected bug with code
2826 initialization which bypassed the variable initializations block.

2838 Documenting changes from previous commits.
2839 * configure.in (version 1.56),
2840 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2841 when generating output files to configure the pic16 library,
2842 but now I've commented it out, since gputils aren't installed in the
2843 SF compile farm, so library won't compile
2845 * device/lib/Makefile.in (version 1.56): initially I've added in
2846 target 'all' the prerequestive 'model-pic16' so it compiled the
2847 pic16 library, but now I've commented it out for the same reasons
2849 * added targets 'model-pic16' and 'objects-pic16' to compile the
2851 * added target 'port-specific-objects-pic16' to handle the
2852 generated libraries and copy them into the build/ directory
2853 * added target 'clean-intermediate-pic16' to clean intermediate
2854 files into pic16 directory
2855 * in target 'installdirs' added line to create directory pic16 in
2856 the installation path
2858 * device/include/Makefile.in (version 1.11): in target 'install'
2859 added lines to copy all header files to installation path,
2860 * in target 'installdirs' added line create directory for pic16
2861 headers in the installation path

2876 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2877 option so that it actually works. Made it specific to the z80, since
2878 the gbz80 doesn't have these kinds of I/O ports.
2880 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2882 * device/include/z180.h,

2904 Mainly changes to support compilation of the device libraries
2905 * src/pic16/device.c: stack is allocated via symbol and not
2906 via literal number. The symbol is placed in the corresponding
2907 position of the data ram
2908 * (pic16_dump_section): relocatable and absolute uninitialized
2909 data are now emitted in sorted order to reduce section naming,
2910 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2911 weren't marked as being in the access bank,
2913 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2915 Added portion of GNU PIC Library under the directory
2916 device/include/pic16 and device/lib/pic16. These files
2917 contain the declarations of SFRs for the PIC18Fxx2 devices.
2918 The directory is initialized via configure from toplevel.
2920 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2922 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

2948 all over. Telling LaTeX to be less strict with word spacing
2949 to better keep the right margin. Changed some notes about
2950 maintainance of the ports in section 3.2.1 - is it OK like this?
2952 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2990 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2992 * src/pic16/peeph.def: all peepholes with movff are commented out,
2993 because there is a problem in the pcode peep optimizer,
2994 * src/pic16/ralloc.c: the register allocator can now reuse local

3135 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3137 * sdcc.spec: updated

3143 * src/ds390/gen.c (genRightShift): fixed bug #870788
3144 * src/SDCCast.c (decorateType): fixed bug #870781
3146 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3148 PIC16 port related changes:
3149 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3150 added variable stackPos,
3152 * gen.c: genCall, assignResultValue: added support for
3153 pushing/retrieving function parameters to/from stack,
3154 genFunction,genEndFunction: setup stack frame for the
3156 genAddrOf: will be changed according to bug 863624
3158 * added files genutils.c and genutils.h which contain gen*
3159 debugged and optimised functions extracted from gen.c
3161 * glue.c: added variable 'externs' which holds extern symbols,
3162 pic16emitRegularMap: is modified to properly handle relocatable
3163 symbols under the new scheme,
3164 pic16createInterruptVect: is modified
3165 pic16printPublics: is modified to emit 'global' assembler directives,
3166 added pic16_printExterns to print extern symbols,
3167 pic16glue: initializes stack/frame pointer in the beginning of
3168 the assembly output. Temporary hack, will be corrected later,
3169 because gplink yet does not support stack and SDCC does not
3170 yet support a type of crt0.o object to create the final binary.
3172 * Removed many lines that contain 8051 legacy code.
3173 * The code is finally placed under a 'code' directive.
3174 * Added port specific options.
3176 * _process_pragma: simplified since now we do not need *special*
3177 include file to define SFR registers. But a separate header
3178 will be needed. This will be developed later.
3179 * _pic16_parseOptions: added, parses port specific options:
3180 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3181 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3182 --preplace-udata-with=
3184 * _pic16_setDefaultOptions: modified to initialize section names,
3185 but hack is temporarly out of order since it needs improvement.
3186 * _pic16_genAssemblerPreamble: configuration words are emitted by
3187 their address instead of their name. This part is incomplete and
3188 supports only the 18Fxx2 devices. Other devices will emit an error
3189 during assembly since they do not contain the same set of config
3191 * _pic16_genIVT: is modified,
3193 * pcode.c: added definitions for some hardware registers that are needed
3195 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3196 All PCI entries are updated. Now LFSR is supported.
3197 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3198 * added pic16_newpCodeOpLit2 to support instructions with
3199 two literal arguments
3200 * pic16_pCode2str: corrected code that emits assembler instructions
3201 with two literal operands and those that have an access bit modifier
3202 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3203 this fixes a bug which caused some labels to be lost, when an
3204 assembler directive was added, i.e. banksel,
3205 * pic16_FixRegisterBanking: improved logic that causes the insertion
3207 * InlineFunction: functions that are called once, are not any more
3208 inlined. This can be a port option in the future,
3210 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3212 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3213 hold the corresponding uninitialized symbols,
3214 * pic16_allocProcessorRegister: registers have explicit marked the
3216 * pic16_allocInternalRegister: registers are explicit marked as
3218 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3219 processing list, so bit registers were lost,
3222 * ralloc.h: added field 'accessBank' and original symbol operand
3223 in register definition,
3224 * removed the field isMapped from register definition,
3226 ** Several functions have been removed from various sources:
3227 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3228 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3229 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3230 pic16_assignRelocatableRegisters
3232 ** others have been introduced:
3233 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3234 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3236 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3238 * support/scripts/inc2h.pl: changed definition of BIT_AT
3239 to emit 'sbit at' instead of 'bit at'. This was a request.
3241 PIC16 port related preliminary changes:
3242 * gen.c: prefixed function popRegFromString with
3243 pic16_ and all references to it corrected
3244 * pcode.c: all pic16_pc_* hardware registers prefixed
3245 with underscore (_),
3246 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3247 * ralloc.c: newReg(): when register is REG_SFR then
3248 set address to rIdx,
3249 pic16_allocProcessorRegister(): marks register wasUsed=0
3250 pic16_writeUsedRegs(): added a call to assign processor
3251 registers via pic16_assignFixedRegisters
3253 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3255 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3256 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3257 variables in unused register banks. Also the SSEG is placed
3258 wherever there is enough space for it, and IDATA can be anywhere
3259 in internal RAM. For now compile using -Wl-Y[stack_size].
3260 The mem file is different for this option as well, since it
3261 makes no sense of talking about DSEG lenght.
3263 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3265 * src/SDCClrange.c: fixed bug 869095 that caused segfault

3510 * src/SDCCast.c (decorateType): disabled a transformation I added in
3511 revision 1.188 (access to fields of a structure at an absolute address);
3512 it breaks with bitfields, extern declarations, and gcse analysis.
3513 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3514 could be assigned through a pointer, so don't complain.

4270 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4271 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4272 fetching of the pointer
4273 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4274 copied from genNearPointerSet()
4275 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4276 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4277 If they pop r0/r1 they must be called in the opposite order than aopOp().
4278 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4279 (resp. --stack-auto), prepared for --xstack

4290 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4292 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4293 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4294 type for bits was changed. It resulted in bit variables becoming
4295 global, which is not permitted in PIC 14 assembly output.
4297 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4299 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4301 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4303 Z80 and MCS51 linkers complaint if a public symbol is defined

4312 A few small changes that speed up the peephole optimizer.
4316 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4318 Try to make the peephole optimizer smarter by maintaining
4319 an association between the assembly source code and the
4320 iCodes that originated them. Put this information to use
4321 with a new peephole rule condition "notVolatile" so that
4322 the rules can be aggressive yet still safe.
4327 * src/mcs51/peeph.def
4329 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4333 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4334 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4335 if the left or right operand symbols have the accuse flag set.
4337 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4339 Changed the type of the result of the ! (NOT) operator to char;
4340 previously it returned the same type as the source. This allows
4341 us to eliminate all the genFloatNot functions (all of its target
4342 implementations were very buggy) since !float can use the same
4345 * src/SDCCicode.c (ast2iCode): ! returns char

4347 * src/ds390/gen.c (genNot, genNotFloat),
4348 * src/z80/gen.c (genNot, genNotFloat),
4349 * src/pic/gen.c (genNot, genNotFloat),

4354 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4355 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4356 during interrupts. Ensure WSAVE is located at a shared bank address.
4357 2. Fixed page selection in some places
4358 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4359 the registers name strings.
4360 4. Fixed "signed / unsigned compare" compiler warnings.
4361 5. The PIC port manages its own allocation of the general purpose
4362 registers, but makes no attempt to reuse them. As a result when
4363 compiling it soon runs out of general purpose registers. Some
4364 additional code was added to the files pcode.c and device.c to walk
4365 through the function call tree and rename the registers so that they
4375 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4376 genPlus() & genMinus() when the result is the same as left or right

4382 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4384 Made bitfield a distinct type from bit so that bitfields
4385 convert as per ANSI C and bits retain their traditional
4386 boolean style behaviour. Implemented bitfield support in
4394 * src/ds390/gen.c: bit v bitfield split
4395 * src/z80/gen.c: New support for bitfields
4396 * support/regression/tests/bitfields.c: reenabled z80,
4399 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4401 Rules 246.x, 247.x relate to bitfields, the others speed up
4402 access to xdata mapped I/O devices.
4404 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4406 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4408 Cleaned up genPackBits and genUnpackBits and added two helper
4409 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4410 for literal assignments in genPackBits (thanks to Frieder for
4416 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4418 Fixed bug #748310 (pointer to function type mishandled when the
4419 function name is omitted). Also fixed a SIGSEGV when a function
4420 attribute (reentrant, etc) is used on a non-function or on a
4421 function but misplaced before the parameter list.
4423 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4425 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4448 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4450 Made the constant following the "interrupt" keyword optional. If
4451 omitted, the function will not automatically be given an entry
4452 in the interrupt vector table (similar to #pragma NOIV, but
4453 less syntacticly kludgy). The interrupt number is also now
4454 range checked. Also fixed a bug in the high order bit example
4461 * support/Util/SDCCerr.c
4462 * support/Util/SDCCerr.h
4465 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4468 * src/SDCCicode.c (operandOperation): rewritten some ops
4469 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4470 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4472 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4473 be re-activated by defining REDUCE_LITERALS)
4474 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4475 unsigned, but are signed by default
4476 * src/SDCCval.c (constVal): rearranged
4477 * src/SDCCval.c (valMod): preliminary fix
4478 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4521 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4522 * src/SDCCval.c (valDiv, valMod): fixed signdness
4523 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4524 signedness of modulo, left and right shift

4930 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4931 the regression tests I'm not brave enough to enable 245.b, 245.c

4933 Using pdflatex this will give you a hyperlinked pdf file with
4934 bookmarks. (prepend '%' before /usepackage if this breaks something)

4981 added --disable-pic16-port
4982 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4983 * src/SDCCmain.c: linkOptions is changed to set *,
4984 added if/endif conditional macros to remove options help
4985 messages from optionsTable when a port is not configured, added
4986 support for the PIc16 port in the ports table, when executing
4987 the compiler with no port specified on command line, a default
4988 port is selected with the new macro DEFAULT_PORT which is
4989 defined in port.h, in setDefaultOptions() linkOptions is removed
4990 from initialization assignment, since now it is a set,
4991 parseCmdLine uses setParseWithComma for linkOptions, in
4992 linkEdit() linkOptions are accessed with new function indexSet()
4993 which returns the i'th item of a set variable. See SDCCset.c, in
4994 linkEdit() when calling buildCmdLine(), added linkOptions as
4995 last argument. Now users can pass arguments to gplink via the
4996 -Wl option, main() uses pic16glue() to glue up pic16 programs

5008 * src/pic16/glue.c: commented out some error producing lines
5009 * src/pic16/main.c: __config directives are commented out to stop
5010 gpasm complaining and test the linkage with gplink, _linkCmd and
5011 _asmCmd changed to be more gplink and gpasm friendly
5012 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5013 produced an error when parsed, peep rule 12 is added to utilize
5014 movff, but it is commented out since the pCode does not support
5015 yet a command with 2 address arguments
5017 2003-05-18 <johan AT balder>
5019 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5046 2003-05-11 Borut Razem <borut.razem AT siol.net>
5048 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5049 the path of bin directory, so that PATH is the only env. variable, which has to be set
5050 in case of standard installation.

6135 file with extension .mem. Reports of overlaping stack and small stack
6136 size. If the space for the stack is less than 16 bytes aslink trows a
6139 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6140 the 8051. Option 'y' for memory summary output file.
6142 Changes to sdcc (All the changes are marked with 'JCF'):
6144 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6146 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6147 overlaying area for it (uses RegBankUsed[4]).
6149 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6150 bank zero as used by default. By default aslink locates the stack
6151 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6152 the creation of the .mem file. Delegates the allocation of data area
6153 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6154 the begining of the stack area to aslink.
6156 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6157 glue() in SDCCglue.c creates an area for it.
6159 2002-09-03 Borut Razem <borut.razem AT siol.net>
6160 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6161 sdcc/src/pic/glue.c:
6162 introduced atexit() handler for teporay files removal in case of
6163 errors, assertions, ...
6165 2002-08-29 Borut Razem <borut.razem AT siol.net>
6166 * sdcc/support/cpp2/auto-host_vc_in.h:
6167 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6168 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6169 Maybe there is a similar problem with BORLANDC? It should be checked!
6171 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6172 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6173 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6174 was not executed, and the compiler (cl) launched a warning:
6175 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6177 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6178 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6180 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6181 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6183 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6184 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6185 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6186 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6187 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6188 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6189 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6190 - added Release configuration in VS projects
6191 - review of compiler an linker options
6192 - VC .exe files are generated in bin_vc directory, not to interfere
6193 with binaries generated from other projects (cygwin, mingw, bcc ...)
6195 * sdcc/src/yacc.dsp: added
6197 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6198 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6199 and insert the version number definitions from .version
6201 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6203 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6204 added - genarate auto-host.h using auto-host_vc_in.h as template
6207 removed from CVS, generated automatically
6209 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6210 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6212 2002-08-11 Borut Razem <borut.razem AT siol.net>
6213 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6215 2002-08-10 Borut Razem <borut.razem AT siol.net>
6216 * src/SDCCmain.c (main):
6217 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6218 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6219 The consequence was that some temporary files were not removed.
6222 unification of code in functions tempfilename() and tempfile():
6223 function tempnam() is defined in Visual Studio 6.0 and .NET
6225 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6227 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6228 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6229 - removed compiler command line option /WX: Treats all warnings as errors
6230 - update a list of source files, included into the project
6232 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6233 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6234 changed project type to Generic Project so that can be correcly converted to VS.NET project
6236 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6238 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6240 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6242 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6243 added return 0 statements after assert() to make compiler happy
6245 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6246 added newline in the def file to keep MSC compiler satisfied
6248 * sdcc/src/z80/gen.c:
6249 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6250 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6251 - solved MSC error in function aopDump()
6253 * sdcc_vc.h: define PREFIX as "\\sdcc"
6255 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6256 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6304 Added -p option. Allows port dependent processor to be specified.
6307 Initialized the new field char *Processor field to NULL in all ports
6310 Compiler generated registers for interrupt context saving
6311 were not getting allocated.
6313 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6316 Fixed left shift. Will promote the left side of a left shift
6317 if a) left shifting more than size of operand or b) when assigned
6318 to something size > size of left side
6320 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6428 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6430 * sdcc/src/SDCCloop.c:
6431 Previous fix was not good. basic blocks that have "break" or "return" are
6432 not really partof a loop , but live ranges used in these blocks should
6433 be live thru the entire loop, so set partOfLoop but don't add them to
6436 2002-02-21 <johan AT FRIJA>
6438 * src/SDCCcse.c: fixed bug #514308
6440 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6444 statement inside a loop, it was not being considered part of the loop.
6446 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6448 2002-02-10 Karl Bongers <karl AT turbobit.com>
