2656 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2658 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2659 loaded with the linker search paths (-L arguments) and the libraries
2660 to be linked with the current source (-l arguments). Changes
2661 currently will affect only the pic16 port.
2662 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2663 include path the port specific paths and port specific libraries,
2664 * gplink command now contains the $3 argument,
2665 * src/pic16/device.h,
2666 * src/pic16/device.c,: structure PIC_device is made public and
2667 renamed to PIC16_device, the same for variable Pics which is renamed

2682 Documenting changes from previous commits.
2683 * configure.in (version 1.56),
2684 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2685 when generating output files to configure the pic16 library,
2686 but now I've commented it out, since gputils aren't installed in the
2687 SF compile farm, so library won't compile
2689 * device/lib/Makefile.in (version 1.56): initially I've added in
2690 target 'all' the prerequestive 'model-pic16' so it compiled the
2691 pic16 library, but now I've commented it out for the same reasons
2693 * added targets 'model-pic16' and 'objects-pic16' to compile the
2695 * added target 'port-specific-objects-pic16' to handle the
2696 generated libraries and copy them into the build/ directory
2697 * added target 'clean-intermediate-pic16' to clean intermediate
2698 files into pic16 directory
2699 * in target 'installdirs' added line to create directory pic16 in
2700 the installation path
2702 * device/include/Makefile.in (version 1.11): in target 'install'
2703 added lines to copy all header files to installation path,
2704 * in target 'installdirs' added line create directory for pic16
2705 headers in the installation path

2720 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2721 option so that it actually works. Made it specific to the z80, since
2722 the gbz80 doesn't have these kinds of I/O ports.
2724 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2726 * device/include/z180.h,

2750 via literal number. The symbol is placed in the corresponding
2751 position of the data ram
2752 * (pic16_dump_section): relocatable and absolute uninitialized
2753 data are now emitted in sorted order to reduce section naming,
2754 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2755 weren't marked as being in the access bank,
2757 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2759 Added portion of GNU PIC Library under the directory
2760 device/include/pic16 and device/lib/pic16. These files
2761 contain the declarations of SFRs for the PIC18Fxx2 devices.
2762 The directory is initialized via configure from toplevel.
2764 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

2792 all over. Telling LaTeX to be less strict with word spacing
2793 to better keep the right margin. Changed some notes about
2794 maintainance of the ports in section 3.2.1 - is it OK like this?
2796 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2834 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2836 * src/pic16/peeph.def: all peepholes with movff are commented out,
2837 because there is a problem in the pcode peep optimizer,
2838 * src/pic16/ralloc.c: the register allocator can now reuse local

2875 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2878 * src/z80/main.c: added missed needLinkerScript flags (more than
2879 one port structure defined in these file)
2880 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2915 2004-01-07 Borut Razem <borut.razem AT siol.net>
2917 * support/scripts/sdcc.nsi: update PATH
2918 * support/scripts/sdcc.ico: craeted

2931 include information about variables allocated to the overlay
2934 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2936 * as/mcs51/lkmain.c: Help about -Y option

2948 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2950 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2951 (default behaviour).
2953 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2955 A python script to validate compiler diagnostic messages. It can be
2956 used to verify that sdcc complains about bad c source code and
2957 gives a good location of the error.
2958 * support/valdiag/Makefile,
2959 * support/valdiag/valdiag.py,
2960 * support/valdiag/tests/*
2962 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2964 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

2976 around the header file.
2977 Bug reported from Jesus Calvino-Fraga
2979 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2981 * sdcc.spec: updated
2982 * device/include/Makefile.in: don't install CVS directories
2983 * device/lib/Makefile.in: added removal of CVS directories after install
2984 * doc/Makefile: fixed install, added local_icons
2985 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2986 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2987 * src/ds390/gen.c (genRightShift): fixed bug #870788
2988 * src/SDCCast.c (decorateType): fixed bug #870781
2990 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2992 PIC16 port related changes:
2993 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2994 added variable stackPos,
2996 * gen.c: genCall, assignResultValue: added support for
2997 pushing/retrieving function parameters to/from stack,
2998 genFunction,genEndFunction: setup stack frame for the
3000 genAddrOf: will be changed according to bug 863624
3002 * added files genutils.c and genutils.h which contain gen*
3003 debugged and optimised functions extracted from gen.c
3005 * glue.c: added variable 'externs' which holds extern symbols,
3006 pic16emitRegularMap: is modified to properly handle relocatable
3007 symbols under the new scheme,
3008 pic16createInterruptVect: is modified
3009 pic16printPublics: is modified to emit 'global' assembler directives,
3010 added pic16_printExterns to print extern symbols,
3011 pic16glue: initializes stack/frame pointer in the beginning of
3012 the assembly output. Temporary hack, will be corrected later,
3013 because gplink yet does not support stack and SDCC does not
3014 yet support a type of crt0.o object to create the final binary.
3016 * Removed many lines that contain 8051 legacy code.
3017 * The code is finally placed under a 'code' directive.
3018 * Added port specific options.
3020 * _process_pragma: simplified since now we do not need *special*
3021 include file to define SFR registers. But a separate header
3022 will be needed. This will be developed later.
3023 * _pic16_parseOptions: added, parses port specific options:
3024 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3025 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3026 --preplace-udata-with=
3028 * _pic16_setDefaultOptions: modified to initialize section names,
3029 but hack is temporarly out of order since it needs improvement.
3030 * _pic16_genAssemblerPreamble: configuration words are emitted by
3031 their address instead of their name. This part is incomplete and
3032 supports only the 18Fxx2 devices. Other devices will emit an error
3033 during assembly since they do not contain the same set of config
3035 * _pic16_genIVT: is modified,
3037 * pcode.c: added definitions for some hardware registers that are needed
3039 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3040 All PCI entries are updated. Now LFSR is supported.
3041 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3042 * added pic16_newpCodeOpLit2 to support instructions with
3043 two literal arguments
3044 * pic16_pCode2str: corrected code that emits assembler instructions
3045 with two literal operands and those that have an access bit modifier
3046 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3047 this fixes a bug which caused some labels to be lost, when an
3048 assembler directive was added, i.e. banksel,
3049 * pic16_FixRegisterBanking: improved logic that causes the insertion
3051 * InlineFunction: functions that are called once, are not any more
3052 inlined. This can be a port option in the future,
3054 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3056 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3057 hold the corresponding uninitialized symbols,
3058 * pic16_allocProcessorRegister: registers have explicit marked the
3060 * pic16_allocInternalRegister: registers are explicit marked as
3062 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3063 processing list, so bit registers were lost,
3066 * ralloc.h: added field 'accessBank' and original symbol operand
3067 in register definition,
3068 * removed the field isMapped from register definition,
3070 ** Several functions have been removed from various sources:
3071 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3072 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3073 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3074 pic16_assignRelocatableRegisters
3076 ** others have been introduced:
3077 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3078 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3080 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3082 * support/scripts/inc2h.pl: changed definition of BIT_AT
3083 to emit 'sbit at' instead of 'bit at'. This was a request.
3085 PIC16 port related preliminary changes:
3086 * gen.c: prefixed function popRegFromString with
3087 pic16_ and all references to it corrected
3088 * pcode.c: all pic16_pc_* hardware registers prefixed
3089 with underscore (_),
3090 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3091 * ralloc.c: newReg(): when register is REG_SFR then
3092 set address to rIdx,
3093 pic16_allocProcessorRegister(): marks register wasUsed=0
3094 pic16_writeUsedRegs(): added a call to assign processor
3095 registers via pic16_assignFixedRegisters
3097 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3099 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3100 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3101 variables in unused register banks. Also the SSEG is placed
3102 wherever there is enough space for it, and IDATA can be anywhere
3103 in internal RAM. For now compile using -Wl-Y[stack_size].
3104 The mem file is different for this option as well, since it
3105 makes no sense of talking about DSEG lenght.
3107 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3109 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3110 in certain cases, e.g. when ROM assignment, patch provided
3111 from Albert den Haan.
3113 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3256 * src/mcs51/peephole.def,
3257 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3258 (allows non-interrupt and interrupt code to safely compete for a resource
3259 without the non-interrupt code having to disable interrupts)
3261 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3263 * src/SDCCicode.c (geniCodeAdd),

3283 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3285 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

3356 it breaks with bitfields, extern declarations, and gcse analysis.
3357 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3358 could be assigned through a pointer, so don't complain.

4136 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4137 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4156 A few small changes that speed up the peephole optimizer.
4160 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4162 Try to make the peephole optimizer smarter by maintaining
4163 an association between the assembly source code and the
4164 iCodes that originated them. Put this information to use
4165 with a new peephole rule condition "notVolatile" so that
4166 the rules can be aggressive yet still safe.
4171 * src/mcs51/peeph.def
4173 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4177 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4178 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4179 if the left or right operand symbols have the accuse flag set.
4181 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4183 Changed the type of the result of the ! (NOT) operator to char;
4184 previously it returned the same type as the source. This allows
4185 us to eliminate all the genFloatNot functions (all of its target
4186 implementations were very buggy) since !float can use the same

4198 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4199 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4200 during interrupts. Ensure WSAVE is located at a shared bank address.
4201 2. Fixed page selection in some places
4202 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4203 the registers name strings.
4204 4. Fixed "signed / unsigned compare" compiler warnings.
4205 5. The PIC port manages its own allocation of the general purpose
4206 registers, but makes no attempt to reuse them. As a result when
4207 compiling it soon runs out of general purpose registers. Some
4208 additional code was added to the files pcode.c and device.c to walk
4209 through the function call tree and rename the registers so that they
4219 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4226 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4228 Made bitfield a distinct type from bit so that bitfields
4229 convert as per ANSI C and bits retain their traditional
4230 boolean style behaviour. Implemented bitfield support in
4238 * src/ds390/gen.c: bit v bitfield split
4239 * src/z80/gen.c: New support for bitfields
4240 * support/regression/tests/bitfields.c: reenabled z80,
4243 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4294 Made the constant following the "interrupt" keyword optional. If
4295 omitted, the function will not automatically be given an entry
4296 in the interrupt vector table (similar to #pragma NOIV, but
4297 less syntacticly kludgy). The interrupt number is also now
4298 range checked. Also fixed a bug in the high order bit example

4820 * src/SDCCmain.c: fixed compiling + linking with object files
4822 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4824 * configure.in: configure for pic16 port,
4825 added --disable-pic16-port
4826 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4827 * src/SDCCmain.c: linkOptions is changed to set *,
4828 added if/endif conditional macros to remove options help
4829 messages from optionsTable when a port is not configured, added
4830 support for the PIc16 port in the ports table, when executing
4831 the compiler with no port specified on command line, a default
4832 port is selected with the new macro DEFAULT_PORT which is
4833 defined in port.h, in setDefaultOptions() linkOptions is removed
4834 from initialization assignment, since now it is a set,
4835 parseCmdLine uses setParseWithComma for linkOptions, in
4836 linkEdit() linkOptions are accessed with new function indexSet()
4837 which returns the i'th item of a set variable. See SDCCset.c, in
4838 linkEdit() when calling buildCmdLine(), added linkOptions as
4839 last argument. Now users can pass arguments to gplink via the
4840 -Wl option, main() uses pic16glue() to glue up pic16 programs
4841 * src/SDCCpeeph.c: various changes to support pic16
4842 * src/SDCCset.c: added function void *indexSet(set *, int) to

4850 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4852 * src/pic16/glue.c: commented out some error producing lines
4853 * src/pic16/main.c: __config directives are commented out to stop
4854 gpasm complaining and test the linkage with gplink, _linkCmd and
4855 _asmCmd changed to be more gplink and gpasm friendly
4856 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4857 produced an error when parsed, peep rule 12 is added to utilize
4858 movff, but it is commented out since the pCode does not support
4859 yet a command with 2 address arguments

4890 2003-05-11 Borut Razem <borut.razem AT siol.net>
4892 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

5902 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5904 2003-01-04 <johan AT balder>
5906 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5908 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5909 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5911 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5921 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5922 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5924 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5926 * in \sdcc\as\mcs51\ changed these files in order to create an
5927 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5928 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5929 following files to include the previous two files: aslink.dsp,
5930 Makefile.aslink, Makefile.bcc, and Makefile.in.
5932 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5933 .adb instead of .cdb
5935 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5937 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5938 value from option --iram-size.
5940 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5942 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5945 2002-09-18 <wiml AT hhhh.org>
5947 * SDCClrange.h: exposed setFromRange() and setToRange()
5948 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5949 packRegsForAccUse() (bug 542397)
5950 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5951 multiple times and emitting the fetch operations more than once
5952 added aopGetUsesAcc() function to allow binary operators to
5953 fetch their operands in the correct order; made genMinus() emit
5954 compact code for X = LITERAL - Y
5956 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5957 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5958 sprintf() in line 1267.
5960 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5961 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5964 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5965 Changes to aslink (All the changes are marked with 'JCF'):
5967 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5970 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5971 area BSEG. Also moves, if possible, the DATA area down into the internal
5972 ram so more space is available.
5974 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5977 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5978 not bytes. Function summary() which creates a memory usage summary
5979 file with extension .mem. Reports of overlaping stack and small stack
5980 size. If the space for the stack is less than 16 bytes aslink trows a
5983 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5984 the 8051. Option 'y' for memory summary output file.
5986 Changes to sdcc (All the changes are marked with 'JCF'):
5988 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5990 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5991 overlaying area for it (uses RegBankUsed[4]).
5993 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5994 bank zero as used by default. By default aslink locates the stack
5995 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5996 the creation of the .mem file. Delegates the allocation of data area
5997 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5998 the begining of the stack area to aslink.
6000 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6001 glue() in SDCCglue.c creates an area for it.
6003 2002-09-03 Borut Razem <borut.razem AT siol.net>
6004 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6005 sdcc/src/pic/glue.c:
6006 introduced atexit() handler for teporay files removal in case of
6007 errors, assertions, ...
6009 2002-08-29 Borut Razem <borut.razem AT siol.net>
6010 * sdcc/support/cpp2/auto-host_vc_in.h:
6011 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6012 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6013 Maybe there is a similar problem with BORLANDC? It should be checked!
6015 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6016 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6017 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6018 was not executed, and the compiler (cl) launched a warning:
6019 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6021 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6022 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6024 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6025 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6027 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6028 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6029 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6030 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6031 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6032 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6033 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6034 - added Release configuration in VS projects
6035 - review of compiler an linker options
6036 - VC .exe files are generated in bin_vc directory, not to interfere
6037 with binaries generated from other projects (cygwin, mingw, bcc ...)
6039 * sdcc/src/yacc.dsp: added
6041 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6042 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6043 and insert the version number definitions from .version
6045 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6047 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6048 added - genarate auto-host.h using auto-host_vc_in.h as template
6051 removed from CVS, generated automatically
6053 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6054 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6056 2002-08-11 Borut Razem <borut.razem AT siol.net>
6057 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6059 2002-08-10 Borut Razem <borut.razem AT siol.net>
6060 * src/SDCCmain.c (main):
6061 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6062 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6063 The consequence was that some temporary files were not removed.
6066 unification of code in functions tempfilename() and tempfile():
6067 function tempnam() is defined in Visual Studio 6.0 and .NET
6069 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6071 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6072 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6073 - removed compiler command line option /WX: Treats all warnings as errors
6074 - update a list of source files, included into the project
6076 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6077 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6078 changed project type to Generic Project so that can be correcly converted to VS.NET project
6080 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6082 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6084 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6086 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6087 added return 0 statements after assert() to make compiler happy
6089 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6090 added newline in the def file to keep MSC compiler satisfied
6092 * sdcc/src/z80/gen.c:
6093 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6094 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6095 - solved MSC error in function aopDump()
6097 * sdcc_vc.h: define PREFIX as "\\sdcc"
6099 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6100 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6102 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6103 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6104 - Rewrote the register banking algorithm.
6105 - Added pCode live-range analysis to registers (for now, only non-used and
6106 singly-used registers optimized away)
6108 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6110 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
6112 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6113 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6115 2002-04-22 Michael Hope <michaelh AT vroom>
