2716 loaded with the linker search paths (-L arguments) and the libraries
2717 to be linked with the current source (-l arguments). Changes
2718 currently will affect only the pic16 port.
2719 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2720 include path the port specific paths and port specific libraries,
2721 * gplink command now contains the $3 argument,
2722 * src/pic16/device.h,

2740 * configure.in (version 1.56),
2741 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2742 when generating output files to configure the pic16 library,
2743 but now I've commented it out, since gputils aren't installed in the
2744 SF compile farm, so library won't compile
2746 * device/lib/Makefile.in (version 1.56): initially I've added in
2747 target 'all' the prerequestive 'model-pic16' so it compiled the
2748 pic16 library, but now I've commented it out for the same reasons
2750 * added targets 'model-pic16' and 'objects-pic16' to compile the
2752 * added target 'port-specific-objects-pic16' to handle the
2753 generated libraries and copy them into the build/ directory
2754 * added target 'clean-intermediate-pic16' to clean intermediate
2755 files into pic16 directory
2756 * in target 'installdirs' added line to create directory pic16 in
2757 the installation path
2759 * device/include/Makefile.in (version 1.11): in target 'install'
2760 added lines to copy all header files to installation path,
2761 * in target 'installdirs' added line create directory for pic16
2762 headers in the installation path
2764 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

2777 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2778 option so that it actually works. Made it specific to the z80, since
2779 the gbz80 doesn't have these kinds of I/O ports.
2781 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2783 * device/include/z180.h,

2805 Mainly changes to support compilation of the device libraries
2806 * src/pic16/device.c: stack is allocated via symbol and not
2807 via literal number. The symbol is placed in the corresponding
2808 position of the data ram
2809 * (pic16_dump_section): relocatable and absolute uninitialized
2810 data are now emitted in sorted order to reduce section naming,
2811 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2812 weren't marked as being in the access bank,
2814 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2816 Added portion of GNU PIC Library under the directory
2817 device/include/pic16 and device/lib/pic16. These files
2818 contain the declarations of SFRs for the PIC18Fxx2 devices.
2819 The directory is initialized via configure from toplevel.
2821 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2823 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2824 the spilllocations to be compared correctly

2849 all over. Telling LaTeX to be less strict with word spacing
2850 to better keep the right margin. Changed some notes about
2851 maintainance of the ports in section 3.2.1 - is it OK like this?
2853 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2890 UPPER for immediate operands,
2891 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2893 * src/pic16/peeph.def: all peepholes with movff are commented out,
2894 because there is a problem in the pcode peep optimizer,
2895 * src/pic16/ralloc.c: the register allocator can now reuse local

2897 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2899 Added file src/pic16/NOTES with information about program writing on
2900 the current port version.

3005 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3007 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3008 (default behaviour).
3010 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3012 A python script to validate compiler diagnostic messages. It can be
3013 used to verify that sdcc complains about bad c source code and
3014 gives a good location of the error.
3015 * support/valdiag/Makefile,
3016 * support/valdiag/valdiag.py,

3034 Bug reported from Jesus Calvino-Fraga
3036 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3038 * sdcc.spec: updated
3039 * device/include/Makefile.in: don't install CVS directories
3040 * device/lib/Makefile.in: added removal of CVS directories after install
3041 * doc/Makefile: fixed install, added local_icons
3042 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3043 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3044 * src/ds390/gen.c (genRightShift): fixed bug #870788
3045 * src/SDCCast.c (decorateType): fixed bug #870781
3047 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3049 PIC16 port related changes:
3050 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3051 added variable stackPos,
3053 * gen.c: genCall, assignResultValue: added support for
3054 pushing/retrieving function parameters to/from stack,
3055 genFunction,genEndFunction: setup stack frame for the
3057 genAddrOf: will be changed according to bug 863624
3059 * added files genutils.c and genutils.h which contain gen*
3060 debugged and optimised functions extracted from gen.c
3062 * glue.c: added variable 'externs' which holds extern symbols,
3063 pic16emitRegularMap: is modified to properly handle relocatable
3064 symbols under the new scheme,
3065 pic16createInterruptVect: is modified
3066 pic16printPublics: is modified to emit 'global' assembler directives,
3067 added pic16_printExterns to print extern symbols,
3068 pic16glue: initializes stack/frame pointer in the beginning of
3069 the assembly output. Temporary hack, will be corrected later,
3070 because gplink yet does not support stack and SDCC does not
3071 yet support a type of crt0.o object to create the final binary.
3073 * Removed many lines that contain 8051 legacy code.
3074 * The code is finally placed under a 'code' directive.
3075 * Added port specific options.
3077 * _process_pragma: simplified since now we do not need *special*
3078 include file to define SFR registers. But a separate header
3079 will be needed. This will be developed later.
3080 * _pic16_parseOptions: added, parses port specific options:
3081 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3082 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3083 --preplace-udata-with=
3085 * _pic16_setDefaultOptions: modified to initialize section names,
3086 but hack is temporarly out of order since it needs improvement.
3087 * _pic16_genAssemblerPreamble: configuration words are emitted by
3088 their address instead of their name. This part is incomplete and
3089 supports only the 18Fxx2 devices. Other devices will emit an error
3090 during assembly since they do not contain the same set of config
3092 * _pic16_genIVT: is modified,
3094 * pcode.c: added definitions for some hardware registers that are needed
3096 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3097 All PCI entries are updated. Now LFSR is supported.
3098 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3099 * added pic16_newpCodeOpLit2 to support instructions with
3100 two literal arguments
3101 * pic16_pCode2str: corrected code that emits assembler instructions
3102 with two literal operands and those that have an access bit modifier
3103 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3104 this fixes a bug which caused some labels to be lost, when an
3105 assembler directive was added, i.e. banksel,
3106 * pic16_FixRegisterBanking: improved logic that causes the insertion
3108 * InlineFunction: functions that are called once, are not any more
3109 inlined. This can be a port option in the future,
3111 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3113 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3114 hold the corresponding uninitialized symbols,
3115 * pic16_allocProcessorRegister: registers have explicit marked the
3117 * pic16_allocInternalRegister: registers are explicit marked as
3119 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3120 processing list, so bit registers were lost,
3123 * ralloc.h: added field 'accessBank' and original symbol operand
3124 in register definition,
3125 * removed the field isMapped from register definition,
3127 ** Several functions have been removed from various sources:
3128 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3129 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3130 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3131 pic16_assignRelocatableRegisters
3133 ** others have been introduced:
3134 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3135 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3137 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3139 * support/scripts/inc2h.pl: changed definition of BIT_AT
3140 to emit 'sbit at' instead of 'bit at'. This was a request.
3142 PIC16 port related preliminary changes:
3143 * gen.c: prefixed function popRegFromString with
3144 pic16_ and all references to it corrected
3145 * pcode.c: all pic16_pc_* hardware registers prefixed
3146 with underscore (_),
3147 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3148 * ralloc.c: newReg(): when register is REG_SFR then
3149 set address to rIdx,
3150 pic16_allocProcessorRegister(): marks register wasUsed=0
3151 pic16_writeUsedRegs(): added a call to assign processor
3152 registers via pic16_assignFixedRegisters
3154 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3156 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3157 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3158 variables in unused register banks. Also the SSEG is placed
3159 wherever there is enough space for it, and IDATA can be anywhere
3160 in internal RAM. For now compile using -Wl-Y[stack_size].
3161 The mem file is different for this option as well, since it
3162 makes no sense of talking about DSEG lenght.
3164 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3166 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3167 in certain cases, e.g. when ROM assignment, patch provided
3168 from Albert den Haan.
3170 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3723 not occur if the control variable is involved with a
3724 relational operator.

4213 A few small changes that speed up the peephole optimizer.
4217 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4219 Try to make the peephole optimizer smarter by maintaining
4220 an association between the assembly source code and the
4221 iCodes that originated them. Put this information to use
4222 with a new peephole rule condition "notVolatile" so that
4223 the rules can be aggressive yet still safe.

4235 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4236 if the left or right operand symbols have the accuse flag set.
4238 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4240 Changed the type of the result of the ! (NOT) operator to char;
4241 previously it returned the same type as the source. This allows
4242 us to eliminate all the genFloatNot functions (all of its target
4243 implementations were very buggy) since !float can use the same
4246 * src/SDCCicode.c (ast2iCode): ! returns char

4255 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4256 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4257 during interrupts. Ensure WSAVE is located at a shared bank address.
4258 2. Fixed page selection in some places
4259 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4260 the registers name strings.
4261 4. Fixed "signed / unsigned compare" compiler warnings.
4262 5. The PIC port manages its own allocation of the general purpose
4263 registers, but makes no attempt to reuse them. As a result when
4264 compiling it soon runs out of general purpose registers. Some
4265 additional code was added to the files pcode.c and device.c to walk
4266 through the function call tree and rename the registers so that they
4276 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4283 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4285 Made bitfield a distinct type from bit so that bitfields
4286 convert as per ANSI C and bits retain their traditional
4287 boolean style behaviour. Implemented bitfield support in
4295 * src/ds390/gen.c: bit v bitfield split
4296 * src/z80/gen.c: New support for bitfields
4297 * support/regression/tests/bitfields.c: reenabled z80,
4300 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4302 Rules 246.x, 247.x relate to bitfields, the others speed up
4303 access to xdata mapped I/O devices.
4305 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4307 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4309 Cleaned up genPackBits and genUnpackBits and added two helper
4310 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4311 for literal assignments in genPackBits (thanks to Frieder for
4317 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4319 Fixed bug #748310 (pointer to function type mishandled when the
4320 function name is omitted). Also fixed a SIGSEGV when a function
4321 attribute (reentrant, etc) is used on a non-function or on a
4322 function but misplaced before the parameter list.

4349 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4351 Made the constant following the "interrupt" keyword optional. If
4352 omitted, the function will not automatically be given an entry
4353 in the interrupt vector table (similar to #pragma NOIV, but
4354 less syntacticly kludgy). The interrupt number is also now
4355 range checked. Also fixed a bug in the high order bit example

4824 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
4825 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
4826 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

4831 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4832 the regression tests I'm not brave enough to enable 245.b, 245.c
4833 * doc/sdccman.lyx: added latex preamble for hyperref package.
4834 Using pdflatex this will give you a hyperlinked pdf file with
4835 bookmarks. (prepend '%' before /usepackage if this breaks something)

4882 added --disable-pic16-port
4883 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4884 * src/SDCCmain.c: linkOptions is changed to set *,
4885 added if/endif conditional macros to remove options help
4886 messages from optionsTable when a port is not configured, added
4887 support for the PIc16 port in the ports table, when executing
4888 the compiler with no port specified on command line, a default
4889 port is selected with the new macro DEFAULT_PORT which is
4890 defined in port.h, in setDefaultOptions() linkOptions is removed
4891 from initialization assignment, since now it is a set,
4892 parseCmdLine uses setParseWithComma for linkOptions, in
4893 linkEdit() linkOptions are accessed with new function indexSet()
4894 which returns the i'th item of a set variable. See SDCCset.c, in
4895 linkEdit() when calling buildCmdLine(), added linkOptions as
4896 last argument. Now users can pass arguments to gplink via the
4897 -Wl option, main() uses pic16glue() to glue up pic16 programs

4909 * src/pic16/glue.c: commented out some error producing lines
4910 * src/pic16/main.c: __config directives are commented out to stop
4911 gpasm complaining and test the linkage with gplink, _linkCmd and
4912 _asmCmd changed to be more gplink and gpasm friendly
4913 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4914 produced an error when parsed, peep rule 12 is added to utilize
4915 movff, but it is commented out since the pCode does not support
4916 yet a command with 2 address arguments
4918 2003-05-18 <johan AT balder>
4920 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4945 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4947 2003-05-11 Borut Razem <borut.razem AT siol.net>
4949 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4950 the path of bin directory, so that PATH is the only env. variable, which has to be set
4951 in case of standard installation.
4952 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5955 * src/SDCCicode.c: fixed array add
5957 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5958 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5959 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5961 2003-01-04 <johan AT balder>
5963 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5965 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5966 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

5978 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5979 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5981 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5983 * in \sdcc\as\mcs51\ changed these files in order to create an
5984 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5985 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5986 following files to include the previous two files: aslink.dsp,
5987 Makefile.aslink, Makefile.bcc, and Makefile.in.
5989 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5990 .adb instead of .cdb
5992 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5994 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5995 value from option --iram-size.
5997 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5999 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6002 2002-09-18 <wiml AT hhhh.org>
6004 * SDCClrange.h: exposed setFromRange() and setToRange()
6005 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6006 packRegsForAccUse() (bug 542397)
6007 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6008 multiple times and emitting the fetch operations more than once
6009 added aopGetUsesAcc() function to allow binary operators to
6010 fetch their operands in the correct order; made genMinus() emit
6011 compact code for X = LITERAL - Y
6013 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6014 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6015 sprintf() in line 1267.
6017 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6018 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6021 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6022 Changes to aslink (All the changes are marked with 'JCF'):
6024 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6027 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6028 area BSEG. Also moves, if possible, the DATA area down into the internal
6029 ram so more space is available.
6031 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6034 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6035 not bytes. Function summary() which creates a memory usage summary
6036 file with extension .mem. Reports of overlaping stack and small stack
6037 size. If the space for the stack is less than 16 bytes aslink trows a
6040 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6041 the 8051. Option 'y' for memory summary output file.
6043 Changes to sdcc (All the changes are marked with 'JCF'):
6045 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6047 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6048 overlaying area for it (uses RegBankUsed[4]).
6050 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6051 bank zero as used by default. By default aslink locates the stack
6052 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6053 the creation of the .mem file. Delegates the allocation of data area
6054 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6055 the begining of the stack area to aslink.
6057 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6058 glue() in SDCCglue.c creates an area for it.
6060 2002-09-03 Borut Razem <borut.razem AT siol.net>
6061 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6062 sdcc/src/pic/glue.c:
6063 introduced atexit() handler for teporay files removal in case of
6064 errors, assertions, ...
6066 2002-08-29 Borut Razem <borut.razem AT siol.net>
6067 * sdcc/support/cpp2/auto-host_vc_in.h:
6068 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6069 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6070 Maybe there is a similar problem with BORLANDC? It should be checked!
6072 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6073 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6074 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6075 was not executed, and the compiler (cl) launched a warning:
6076 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6078 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6079 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6081 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6082 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6084 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6085 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6087 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6088 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6089 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6090 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6091 - added Release configuration in VS projects
6092 - review of compiler an linker options
6093 - VC .exe files are generated in bin_vc directory, not to interfere
6094 with binaries generated from other projects (cygwin, mingw, bcc ...)
6096 * sdcc/src/yacc.dsp: added
6098 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6099 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6100 and insert the version number definitions from .version
6102 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6104 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6105 added - genarate auto-host.h using auto-host_vc_in.h as template
6108 removed from CVS, generated automatically
6110 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6111 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6113 2002-08-11 Borut Razem <borut.razem AT siol.net>
6114 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6116 2002-08-10 Borut Razem <borut.razem AT siol.net>
6117 * src/SDCCmain.c (main):
6118 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6119 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6120 The consequence was that some temporary files were not removed.
6123 unification of code in functions tempfilename() and tempfile():
6124 function tempnam() is defined in Visual Studio 6.0 and .NET
6126 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6128 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6129 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6130 - removed compiler command line option /WX: Treats all warnings as errors
6131 - update a list of source files, included into the project
6133 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

6147 added newline in the def file to keep MSC compiler satisfied
6149 * sdcc/src/z80/gen.c:
6150 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6151 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC

6331 * sdcc/src/SDCCloop.c:
6332 Previous fix was not good. basic blocks that have "break" or "return" are
6333 not really partof a loop , but live ranges used in these blocks should
6334 be live thru the entire loop, so set partOfLoop but don't add them to
