2720 loaded with the linker search paths (-L arguments) and the libraries
2721 to be linked with the current source (-l arguments). Changes
2722 currently will affect only the pic16 port.
2723 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2724 include path the port specific paths and port specific libraries,

2741 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2743 Documenting changes from previous commits.
2744 * configure.in (version 1.56),
2745 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2746 when generating output files to configure the pic16 library,
2747 but now I've commented it out, since gputils aren't installed in the
2748 SF compile farm, so library won't compile
2750 * device/lib/Makefile.in (version 1.56): initially I've added in
2751 target 'all' the prerequestive 'model-pic16' so it compiled the
2752 pic16 library, but now I've commented it out for the same reasons
2754 * added targets 'model-pic16' and 'objects-pic16' to compile the
2756 * added target 'port-specific-objects-pic16' to handle the
2757 generated libraries and copy them into the build/ directory
2758 * added target 'clean-intermediate-pic16' to clean intermediate
2759 files into pic16 directory
2760 * in target 'installdirs' added line to create directory pic16 in
2761 the installation path
2763 * device/include/Makefile.in (version 1.11): in target 'install'
2764 added lines to copy all header files to installation path,
2765 * in target 'installdirs' added line create directory for pic16
2766 headers in the installation path
2768 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

2781 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2782 option so that it actually works. Made it specific to the z80, since
2783 the gbz80 doesn't have these kinds of I/O ports.
2785 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2787 * device/include/z180.h,

2800 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2802 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2803 changed interrupt vector table generation to only emit declared vectors.

2809 Mainly changes to support compilation of the device libraries
2810 * src/pic16/device.c: stack is allocated via symbol and not
2811 via literal number. The symbol is placed in the corresponding
2812 position of the data ram
2813 * (pic16_dump_section): relocatable and absolute uninitialized
2814 data are now emitted in sorted order to reduce section naming,
2815 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2816 weren't marked as being in the access bank,
2818 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2820 Added portion of GNU PIC Library under the directory
2821 device/include/pic16 and device/lib/pic16. These files
2822 contain the declarations of SFRs for the PIC18Fxx2 devices.
2823 The directory is initialized via configure from toplevel.
2825 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2827 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2828 the spilllocations to be compared correctly
2830 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

2852 * doc/sdccman.lyx: Moved and added some sections, small changes
2853 all over. Telling LaTeX to be less strict with word spacing
2854 to better keep the right margin. Changed some notes about
2855 maintainance of the ports in section 3.2.1 - is it OK like this?
2857 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2894 UPPER for immediate operands,
2895 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2897 * src/pic16/peeph.def: all peepholes with movff are commented out,
2898 because there is a problem in the pcode peep optimizer,
2899 * src/pic16/ralloc.c: the register allocator can now reuse local

2901 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2903 Added file src/pic16/NOTES with information about program writing on
2904 the current port version.

2976 2004-01-07 Borut Razem <borut.razem AT siol.net>
2978 * support/scripts/sdcc.nsi: update PATH
2979 * support/scripts/sdcc.ico: craeted

2992 include information about variables allocated to the overlay
2995 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2997 * as/mcs51/lkmain.c: Help about -Y option

3009 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3011 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3012 (default behaviour).
3014 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3016 A python script to validate compiler diagnostic messages. It can be
3017 used to verify that sdcc complains about bad c source code and
3018 gives a good location of the error.
3019 * support/valdiag/Makefile,
3020 * support/valdiag/valdiag.py,
3021 * support/valdiag/tests/*
3023 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3038 Bug reported from Jesus Calvino-Fraga
3040 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3042 * sdcc.spec: updated
3043 * device/include/Makefile.in: don't install CVS directories
3044 * device/lib/Makefile.in: added removal of CVS directories after install
3045 * doc/Makefile: fixed install, added local_icons
3046 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3047 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3048 * src/ds390/gen.c (genRightShift): fixed bug #870788
3049 * src/SDCCast.c (decorateType): fixed bug #870781
3051 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3053 PIC16 port related changes:
3054 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3055 added variable stackPos,
3057 * gen.c: genCall, assignResultValue: added support for
3058 pushing/retrieving function parameters to/from stack,
3059 genFunction,genEndFunction: setup stack frame for the
3061 genAddrOf: will be changed according to bug 863624
3063 * added files genutils.c and genutils.h which contain gen*
3064 debugged and optimised functions extracted from gen.c
3066 * glue.c: added variable 'externs' which holds extern symbols,
3067 pic16emitRegularMap: is modified to properly handle relocatable
3068 symbols under the new scheme,
3069 pic16createInterruptVect: is modified
3070 pic16printPublics: is modified to emit 'global' assembler directives,
3071 added pic16_printExterns to print extern symbols,
3072 pic16glue: initializes stack/frame pointer in the beginning of
3073 the assembly output. Temporary hack, will be corrected later,
3074 because gplink yet does not support stack and SDCC does not
3075 yet support a type of crt0.o object to create the final binary.
3077 * Removed many lines that contain 8051 legacy code.
3078 * The code is finally placed under a 'code' directive.
3079 * Added port specific options.
3081 * _process_pragma: simplified since now we do not need *special*
3082 include file to define SFR registers. But a separate header
3083 will be needed. This will be developed later.
3084 * _pic16_parseOptions: added, parses port specific options:
3085 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3086 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3087 --preplace-udata-with=
3089 * _pic16_setDefaultOptions: modified to initialize section names,
3090 but hack is temporarly out of order since it needs improvement.
3091 * _pic16_genAssemblerPreamble: configuration words are emitted by
3092 their address instead of their name. This part is incomplete and
3093 supports only the 18Fxx2 devices. Other devices will emit an error
3094 during assembly since they do not contain the same set of config
3096 * _pic16_genIVT: is modified,
3098 * pcode.c: added definitions for some hardware registers that are needed
3100 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3101 All PCI entries are updated. Now LFSR is supported.
3102 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3103 * added pic16_newpCodeOpLit2 to support instructions with
3104 two literal arguments
3105 * pic16_pCode2str: corrected code that emits assembler instructions
3106 with two literal operands and those that have an access bit modifier
3107 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3108 this fixes a bug which caused some labels to be lost, when an
3109 assembler directive was added, i.e. banksel,
3110 * pic16_FixRegisterBanking: improved logic that causes the insertion
3112 * InlineFunction: functions that are called once, are not any more
3113 inlined. This can be a port option in the future,
3115 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3117 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3118 hold the corresponding uninitialized symbols,
3119 * pic16_allocProcessorRegister: registers have explicit marked the
3121 * pic16_allocInternalRegister: registers are explicit marked as
3123 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3124 processing list, so bit registers were lost,
3127 * ralloc.h: added field 'accessBank' and original symbol operand
3128 in register definition,
3129 * removed the field isMapped from register definition,
3131 ** Several functions have been removed from various sources:
3132 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3133 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3134 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3135 pic16_assignRelocatableRegisters
3137 ** others have been introduced:
3138 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3139 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3141 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3143 * support/scripts/inc2h.pl: changed definition of BIT_AT
3144 to emit 'sbit at' instead of 'bit at'. This was a request.
3146 PIC16 port related preliminary changes:
3147 * gen.c: prefixed function popRegFromString with
3148 pic16_ and all references to it corrected
3149 * pcode.c: all pic16_pc_* hardware registers prefixed
3150 with underscore (_),
3151 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3152 * ralloc.c: newReg(): when register is REG_SFR then
3153 set address to rIdx,
3154 pic16_allocProcessorRegister(): marks register wasUsed=0
3155 pic16_writeUsedRegs(): added a call to assign processor
3156 registers via pic16_assignFixedRegisters
3158 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3160 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3161 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3162 variables in unused register banks. Also the SSEG is placed
3163 wherever there is enough space for it, and IDATA can be anywhere
3164 in internal RAM. For now compile using -Wl-Y[stack_size].
3165 The mem file is different for this option as well, since it
3166 makes no sense of talking about DSEG lenght.
3168 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3170 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3171 in certain cases, e.g. when ROM assignment, patch provided
3172 from Albert den Haan.
3174 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4217 A few small changes that speed up the peephole optimizer.
4221 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4223 Try to make the peephole optimizer smarter by maintaining
4224 an association between the assembly source code and the
4225 iCodes that originated them. Put this information to use
4226 with a new peephole rule condition "notVolatile" so that
4227 the rules can be aggressive yet still safe.
4232 * src/mcs51/peeph.def
4234 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4238 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4239 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4240 if the left or right operand symbols have the accuse flag set.
4242 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4244 Changed the type of the result of the ! (NOT) operator to char;
4245 previously it returned the same type as the source. This allows
4246 us to eliminate all the genFloatNot functions (all of its target
4247 implementations were very buggy) since !float can use the same
4250 * src/SDCCicode.c (ast2iCode): ! returns char

4259 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4260 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4261 during interrupts. Ensure WSAVE is located at a shared bank address.
4262 2. Fixed page selection in some places
4263 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4264 the registers name strings.
4265 4. Fixed "signed / unsigned compare" compiler warnings.
4266 5. The PIC port manages its own allocation of the general purpose
4267 registers, but makes no attempt to reuse them. As a result when
4268 compiling it soon runs out of general purpose registers. Some
4269 additional code was added to the files pcode.c and device.c to walk
4270 through the function call tree and rename the registers so that they
4280 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4287 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4289 Made bitfield a distinct type from bit so that bitfields
4290 convert as per ANSI C and bits retain their traditional
4291 boolean style behaviour. Implemented bitfield support in
4299 * src/ds390/gen.c: bit v bitfield split
4300 * src/z80/gen.c: New support for bitfields
4301 * support/regression/tests/bitfields.c: reenabled z80,
4304 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4306 Rules 246.x, 247.x relate to bitfields, the others speed up
4307 access to xdata mapped I/O devices.
4309 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4311 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4313 Cleaned up genPackBits and genUnpackBits and added two helper
4314 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4315 for literal assignments in genPackBits (thanks to Frieder for
4321 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4323 Fixed bug #748310 (pointer to function type mishandled when the
4324 function name is omitted). Also fixed a SIGSEGV when a function
4325 attribute (reentrant, etc) is used on a non-function or on a
4326 function but misplaced before the parameter list.

4353 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4355 Made the constant following the "interrupt" keyword optional. If
4356 omitted, the function will not automatically be given an entry
4357 in the interrupt vector table (similar to #pragma NOIV, but
4358 less syntacticly kludgy). The interrupt number is also now
4359 range checked. Also fixed a bug in the high order bit example

4828 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
4829 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
4830 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
4833 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4835 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4836 the regression tests I'm not brave enough to enable 245.b, 245.c
4837 * doc/sdccman.lyx: added latex preamble for hyperref package.
4838 Using pdflatex this will give you a hyperlinked pdf file with
4839 bookmarks. (prepend '%' before /usepackage if this breaks something)

4880 it can be defined with CFLAGS when running configure
4881 * src/SDCCmain.c: fixed compiling + linking with object files
4883 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4886 added --disable-pic16-port
4887 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4888 * src/SDCCmain.c: linkOptions is changed to set *,
4889 added if/endif conditional macros to remove options help
4890 messages from optionsTable when a port is not configured, added
4891 support for the PIc16 port in the ports table, when executing
4892 the compiler with no port specified on command line, a default
4893 port is selected with the new macro DEFAULT_PORT which is
4894 defined in port.h, in setDefaultOptions() linkOptions is removed
4895 from initialization assignment, since now it is a set,
4896 parseCmdLine uses setParseWithComma for linkOptions, in
4897 linkEdit() linkOptions are accessed with new function indexSet()
4898 which returns the i'th item of a set variable. See SDCCset.c, in
4899 linkEdit() when calling buildCmdLine(), added linkOptions as
4900 last argument. Now users can pass arguments to gplink via the
4901 -Wl option, main() uses pic16glue() to glue up pic16 programs
4902 * src/SDCCpeeph.c: various changes to support pic16

4913 * src/pic16/glue.c: commented out some error producing lines
4914 * src/pic16/main.c: __config directives are commented out to stop
4915 gpasm complaining and test the linkage with gplink, _linkCmd and
4916 _asmCmd changed to be more gplink and gpasm friendly
4917 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4918 produced an error when parsed, peep rule 12 is added to utilize
4919 movff, but it is commented out since the pCode does not support
4920 yet a command with 2 address arguments
4922 2003-05-18 <johan AT balder>
4924 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4925 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4949 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4951 2003-05-11 Borut Razem <borut.razem AT siol.net>
4953 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4954 the path of bin directory, so that PATH is the only env. variable, which has to be set
4955 in case of standard installation.
4956 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5959 * src/SDCCicode.c: fixed array add
5961 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5962 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5963 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5965 2003-01-04 <johan AT balder>
5967 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5969 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5970 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

5982 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5983 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5985 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5987 * in \sdcc\as\mcs51\ changed these files in order to create an
5988 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5989 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5990 following files to include the previous two files: aslink.dsp,
5991 Makefile.aslink, Makefile.bcc, and Makefile.in.
5993 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5994 .adb instead of .cdb
5996 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5998 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5999 value from option --iram-size.
6001 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6003 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6006 2002-09-18 <wiml AT hhhh.org>
6008 * SDCClrange.h: exposed setFromRange() and setToRange()
6009 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6010 packRegsForAccUse() (bug 542397)
6011 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6012 multiple times and emitting the fetch operations more than once
6013 added aopGetUsesAcc() function to allow binary operators to
6014 fetch their operands in the correct order; made genMinus() emit
6015 compact code for X = LITERAL - Y
6017 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6018 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6019 sprintf() in line 1267.
6021 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6022 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6025 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6026 Changes to aslink (All the changes are marked with 'JCF'):
6028 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6031 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6032 area BSEG. Also moves, if possible, the DATA area down into the internal
6033 ram so more space is available.
6035 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6038 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6039 not bytes. Function summary() which creates a memory usage summary
6040 file with extension .mem. Reports of overlaping stack and small stack
6041 size. If the space for the stack is less than 16 bytes aslink trows a
6044 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6045 the 8051. Option 'y' for memory summary output file.
6047 Changes to sdcc (All the changes are marked with 'JCF'):
6049 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6051 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6052 overlaying area for it (uses RegBankUsed[4]).
6054 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6055 bank zero as used by default. By default aslink locates the stack
6056 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6057 the creation of the .mem file. Delegates the allocation of data area
6058 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6059 the begining of the stack area to aslink.
6061 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6062 glue() in SDCCglue.c creates an area for it.
6064 2002-09-03 Borut Razem <borut.razem AT siol.net>
6065 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6066 sdcc/src/pic/glue.c:
6067 introduced atexit() handler for teporay files removal in case of
6068 errors, assertions, ...
6070 2002-08-29 Borut Razem <borut.razem AT siol.net>
6071 * sdcc/support/cpp2/auto-host_vc_in.h:
6072 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6073 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6074 Maybe there is a similar problem with BORLANDC? It should be checked!
6076 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6077 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6078 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6079 was not executed, and the compiler (cl) launched a warning:
6080 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6082 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6083 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6085 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6086 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6088 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6089 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6091 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6092 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6093 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6094 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6095 - added Release configuration in VS projects
6096 - review of compiler an linker options
6097 - VC .exe files are generated in bin_vc directory, not to interfere
6098 with binaries generated from other projects (cygwin, mingw, bcc ...)
6100 * sdcc/src/yacc.dsp: added
6102 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6103 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6104 and insert the version number definitions from .version
6106 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6108 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6109 added - genarate auto-host.h using auto-host_vc_in.h as template
6112 removed from CVS, generated automatically
6114 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6115 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6117 2002-08-11 Borut Razem <borut.razem AT siol.net>
6118 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6120 2002-08-10 Borut Razem <borut.razem AT siol.net>
6121 * src/SDCCmain.c (main):
6122 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6123 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6124 The consequence was that some temporary files were not removed.
6127 unification of code in functions tempfilename() and tempfile():
6128 function tempnam() is defined in Visual Studio 6.0 and .NET
6130 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6132 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6133 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6134 - removed compiler command line option /WX: Treats all warnings as errors
6135 - update a list of source files, included into the project
6137 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

6336 Previous fix was not good. basic blocks that have "break" or "return" are
6337 not really partof a loop , but live ranges used in these blocks should
