2534 loaded with the linker search paths (-L arguments) and the libraries
2535 to be linked with the current source (-l arguments). Changes
2536 currently will affect only the pic16 port.
2537 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2538 include path the port specific paths and port specific libraries,
2539 * gplink command now contains the $3 argument,
2540 * src/pic16/device.h,
2541 * src/pic16/device.c,: structure PIC_device is made public and

2557 Documenting changes from previous commits.
2558 * configure.in (version 1.56),
2559 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2560 when generating output files to configure the pic16 library,
2561 but now I've commented it out, since gputils aren't installed in the
2562 SF compile farm, so library won't compile
2564 * device/lib/Makefile.in (version 1.56): initially I've added in
2565 target 'all' the prerequestive 'model-pic16' so it compiled the
2566 pic16 library, but now I've commented it out for the same reasons
2568 * added targets 'model-pic16' and 'objects-pic16' to compile the
2570 * added target 'port-specific-objects-pic16' to handle the
2571 generated libraries and copy them into the build/ directory
2572 * added target 'clean-intermediate-pic16' to clean intermediate
2573 files into pic16 directory
2574 * in target 'installdirs' added line to create directory pic16 in

2771 needLinkerScript flag
2773 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2774 * src/pic/glue.c: added variable udata_section_name to
2775 override default uninitialized data segment definition for
2776 devices only with SHAREBANK memory (reported from Erik Epetrich)
2777 * (pic14emitOverlay): modified to emit a commented overlay segment
2778 directive when no overlay data exist
2779 * (picglue): modified to emit uninitialized data segment
2780 according to udata_section_name

2785 arguments via -W option
2786 * src/pic16/main.c: added $l in _asmCmd, changed extension for
2787 object file from '.rel' to '.o' in port->linker structure,
2788 changed size of fptr from 2 to 3 in port structure
2790 2004-01-07 Borut Razem <borut.razem AT siol.net>
2792 * support/scripts/sdcc.nsi: update PATH
2793 * support/scripts/sdcc.ico: craeted

2809 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2811 * as/mcs51/lkmain.c: Help about -Y option
2812 * as/mcs51/lkarea.c: Fixed gcc warnings
2814 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

2818 * support/valdiag/tests/overflow.c: added
2819 * src/SDCCast.c (decorateType),
2820 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
2821 LEFT_OP (left shift)
2823 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2825 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2826 (default behaviour).
2828 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2830 A python script to validate compiler diagnostic messages. It can be
2831 used to verify that sdcc complains about bad c source code and
2832 gives a good location of the error.
2833 * support/valdiag/Makefile,
2834 * support/valdiag/valdiag.py,
2835 * support/valdiag/tests/*
2837 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2839 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
2840 * src/SDCCsymt.c (newEnumType),

2848 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2850 * src/common.h: added ifndef/define/endif macros
2851 around the header file.
2852 Bug reported from Jesus Calvino-Fraga
2854 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2856 * sdcc.spec: updated
2857 * device/include/Makefile.in: don't install CVS directories
2858 * device/lib/Makefile.in: added removal of CVS directories after install
2859 * doc/Makefile: fixed install, added local_icons
2860 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2861 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2862 * src/ds390/gen.c (genRightShift): fixed bug #870788
2863 * src/SDCCast.c (decorateType): fixed bug #870781
2865 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2867 PIC16 port related changes:
2868 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2869 added variable stackPos,
2871 * gen.c: genCall, assignResultValue: added support for
2872 pushing/retrieving function parameters to/from stack,
2873 genFunction,genEndFunction: setup stack frame for the
2875 genAddrOf: will be changed according to bug 863624
2877 * added files genutils.c and genutils.h which contain gen*
2878 debugged and optimised functions extracted from gen.c
2880 * glue.c: added variable 'externs' which holds extern symbols,
2881 pic16emitRegularMap: is modified to properly handle relocatable
2882 symbols under the new scheme,
2883 pic16createInterruptVect: is modified
2884 pic16printPublics: is modified to emit 'global' assembler directives,
2885 added pic16_printExterns to print extern symbols,
2886 pic16glue: initializes stack/frame pointer in the beginning of
2887 the assembly output. Temporary hack, will be corrected later,
2888 because gplink yet does not support stack and SDCC does not
2889 yet support a type of crt0.o object to create the final binary.
2891 * Removed many lines that contain 8051 legacy code.
2892 * The code is finally placed under a 'code' directive.
2893 * Added port specific options.
2895 * _process_pragma: simplified since now we do not need *special*
2896 include file to define SFR registers. But a separate header
2897 will be needed. This will be developed later.
2898 * _pic16_parseOptions: added, parses port specific options:
2899 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2900 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2901 --preplace-udata-with=
2903 * _pic16_setDefaultOptions: modified to initialize section names,
2904 but hack is temporarly out of order since it needs improvement.
2905 * _pic16_genAssemblerPreamble: configuration words are emitted by
2906 their address instead of their name. This part is incomplete and
2907 supports only the 18Fxx2 devices. Other devices will emit an error
2908 during assembly since they do not contain the same set of config
2910 * _pic16_genIVT: is modified,
2912 * pcode.c: added definitions for some hardware registers that are needed
2914 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2915 All PCI entries are updated. Now LFSR is supported.
2916 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2917 * added pic16_newpCodeOpLit2 to support instructions with
2918 two literal arguments
2919 * pic16_pCode2str: corrected code that emits assembler instructions
2920 with two literal operands and those that have an access bit modifier
2921 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2922 this fixes a bug which caused some labels to be lost, when an
2923 assembler directive was added, i.e. banksel,
2924 * pic16_FixRegisterBanking: improved logic that causes the insertion
2926 * InlineFunction: functions that are called once, are not any more
2927 inlined. This can be a port option in the future,
2929 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2931 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2932 hold the corresponding uninitialized symbols,
2933 * pic16_allocProcessorRegister: registers have explicit marked the
2935 * pic16_allocInternalRegister: registers are explicit marked as
2937 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2938 processing list, so bit registers were lost,
2941 * ralloc.h: added field 'accessBank' and original symbol operand
2942 in register definition,
2943 * removed the field isMapped from register definition,
2945 ** Several functions have been removed from various sources:
2946 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2947 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2948 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2949 pic16_assignRelocatableRegisters
2951 ** others have been introduced:
2952 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2953 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2955 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2957 * support/scripts/inc2h.pl: changed definition of BIT_AT
2958 to emit 'sbit at' instead of 'bit at'. This was a request.
2960 PIC16 port related preliminary changes:
2961 * gen.c: prefixed function popRegFromString with
2962 pic16_ and all references to it corrected
2963 * pcode.c: all pic16_pc_* hardware registers prefixed
2964 with underscore (_),
2965 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2966 * ralloc.c: newReg(): when register is REG_SFR then
2967 set address to rIdx,
2968 pic16_allocProcessorRegister(): marks register wasUsed=0
2969 pic16_writeUsedRegs(): added a call to assign processor
2970 registers via pic16_assignFixedRegisters
2972 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2974 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2975 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2976 variables in unused register banks. Also the SSEG is placed
2977 wherever there is enough space for it, and IDATA can be anywhere
2978 in internal RAM. For now compile using -Wl-Y[stack_size].
2979 The mem file is different for this option as well, since it
2980 makes no sense of talking about DSEG lenght.
2982 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2984 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2985 in certain cases, e.g. when ROM assignment, patch provided
2986 from Albert den Haan.

3227 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3229 * src/SDCCast.c (decorateType): disabled a transformation I added in
3230 revision 1.188 (access to fields of a structure at an absolute address);
3231 it breaks with bitfields, extern declarations, and gcse analysis.
3232 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it

3991 fetching of the pointer
3992 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3993 copied from genNearPointerSet()
3994 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3995 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4011 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4012 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4013 type for bits was changed. It resulted in bit variables becoming
4014 global, which is not permitted in PIC 14 assembly output.

4031 A few small changes that speed up the peephole optimizer.
4035 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4037 Try to make the peephole optimizer smarter by maintaining
4038 an association between the assembly source code and the
4039 iCodes that originated them. Put this information to use
4040 with a new peephole rule condition "notVolatile" so that
4041 the rules can be aggressive yet still safe.
4046 * src/mcs51/peeph.def
4048 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4052 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4053 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4054 if the left or right operand symbols have the accuse flag set.
4056 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4058 Changed the type of the result of the ! (NOT) operator to char;
4059 previously it returned the same type as the source. This allows
4060 us to eliminate all the genFloatNot functions (all of its target
4061 implementations were very buggy) since !float can use the same

4073 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4074 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4075 during interrupts. Ensure WSAVE is located at a shared bank address.
4076 2. Fixed page selection in some places
4077 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4078 the registers name strings.
4079 4. Fixed "signed / unsigned compare" compiler warnings.
4080 5. The PIC port manages its own allocation of the general purpose
4081 registers, but makes no attempt to reuse them. As a result when
4082 compiling it soon runs out of general purpose registers. Some
4083 additional code was added to the files pcode.c and device.c to walk
4084 through the function call tree and rename the registers so that they
4094 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4101 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4103 Made bitfield a distinct type from bit so that bitfields
4104 convert as per ANSI C and bits retain their traditional
4105 boolean style behaviour. Implemented bitfield support in
4113 * src/ds390/gen.c: bit v bitfield split
4114 * src/z80/gen.c: New support for bitfields
4115 * support/regression/tests/bitfields.c: reenabled z80,
4118 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4120 Rules 246.x, 247.x relate to bitfields, the others speed up
4121 access to xdata mapped I/O devices.
4123 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4125 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4127 Cleaned up genPackBits and genUnpackBits and added two helper

4137 Fixed bug #748310 (pointer to function type mishandled when the
4138 function name is omitted). Also fixed a SIGSEGV when a function
4139 attribute (reentrant, etc) is used on a non-function or on a
4140 function but misplaced before the parameter list.

4167 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4169 Made the constant following the "interrupt" keyword optional. If
4170 omitted, the function will not automatically be given an entry
4171 in the interrupt vector table (similar to #pragma NOIV, but
4172 less syntacticly kludgy). The interrupt number is also now
4173 range checked. Also fixed a bug in the high order bit example

4704 messages from optionsTable when a port is not configured, added
4705 support for the PIc16 port in the ports table, when executing
4706 the compiler with no port specified on command line, a default
4707 port is selected with the new macro DEFAULT_PORT which is
4708 defined in port.h, in setDefaultOptions() linkOptions is removed
4709 from initialization assignment, since now it is a set,
4710 parseCmdLine uses setParseWithComma for linkOptions, in
4711 linkEdit() linkOptions are accessed with new function indexSet()
4712 which returns the i'th item of a set variable. See SDCCset.c, in
4713 linkEdit() when calling buildCmdLine(), added linkOptions as
4714 last argument. Now users can pass arguments to gplink via the
4715 -Wl option, main() uses pic16glue() to glue up pic16 programs

4729 gpasm complaining and test the linkage with gplink, _linkCmd and
4730 _asmCmd changed to be more gplink and gpasm friendly
4731 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4732 produced an error when parsed, peep rule 12 is added to utilize
4733 movff, but it is commented out since the pCode does not support
4734 yet a command with 2 address arguments
4736 2003-05-18 <johan AT balder>
4738 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4765 2003-05-11 Borut Razem <borut.razem AT siol.net>
4767 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

5773 * src/SDCCicode.c: fixed array add
5775 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5776 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5777 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5779 2003-01-04 <johan AT balder>
5781 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5783 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5784 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5786 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5787 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

5796 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5797 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5799 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5801 * in \sdcc\as\mcs51\ changed these files in order to create an
5802 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5803 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5804 following files to include the previous two files: aslink.dsp,
5805 Makefile.aslink, Makefile.bcc, and Makefile.in.
5807 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5808 .adb instead of .cdb
5810 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5812 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5813 value from option --iram-size.
5815 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5817 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5820 2002-09-18 <wiml AT hhhh.org>
5822 * SDCClrange.h: exposed setFromRange() and setToRange()
5823 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5824 packRegsForAccUse() (bug 542397)
5825 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5826 multiple times and emitting the fetch operations more than once
5827 added aopGetUsesAcc() function to allow binary operators to
5828 fetch their operands in the correct order; made genMinus() emit
5829 compact code for X = LITERAL - Y
5831 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5832 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5833 sprintf() in line 1267.
5835 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5836 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5839 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5840 Changes to aslink (All the changes are marked with 'JCF'):
5842 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5845 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5846 area BSEG. Also moves, if possible, the DATA area down into the internal
5847 ram so more space is available.
5849 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5852 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5853 not bytes. Function summary() which creates a memory usage summary
5854 file with extension .mem. Reports of overlaping stack and small stack
5855 size. If the space for the stack is less than 16 bytes aslink trows a
5858 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5859 the 8051. Option 'y' for memory summary output file.
5861 Changes to sdcc (All the changes are marked with 'JCF'):
5863 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5865 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5866 overlaying area for it (uses RegBankUsed[4]).
5868 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5869 bank zero as used by default. By default aslink locates the stack
5870 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5871 the creation of the .mem file. Delegates the allocation of data area
5872 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5873 the begining of the stack area to aslink.
5875 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5876 glue() in SDCCglue.c creates an area for it.
5878 2002-09-03 Borut Razem <borut.razem AT siol.net>
5879 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5880 sdcc/src/pic/glue.c:
5881 introduced atexit() handler for teporay files removal in case of
5882 errors, assertions, ...
5884 2002-08-29 Borut Razem <borut.razem AT siol.net>
5885 * sdcc/support/cpp2/auto-host_vc_in.h:
5886 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5887 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5888 Maybe there is a similar problem with BORLANDC? It should be checked!
5890 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5891 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5892 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5893 was not executed, and the compiler (cl) launched a warning:
5894 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5896 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5897 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5899 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5900 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5902 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5903 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5904 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5905 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5906 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5907 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5908 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5909 - added Release configuration in VS projects
5910 - review of compiler an linker options
5911 - VC .exe files are generated in bin_vc directory, not to interfere
5912 with binaries generated from other projects (cygwin, mingw, bcc ...)
5914 * sdcc/src/yacc.dsp: added
5916 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5917 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5918 and insert the version number definitions from .version
5920 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5922 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5923 added - genarate auto-host.h using auto-host_vc_in.h as template
5926 removed from CVS, generated automatically
5928 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5929 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5931 2002-08-11 Borut Razem <borut.razem AT siol.net>
5932 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5934 2002-08-10 Borut Razem <borut.razem AT siol.net>
5935 * src/SDCCmain.c (main):
5936 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5937 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5938 The consequence was that some temporary files were not removed.
5941 unification of code in functions tempfilename() and tempfile():
5942 function tempnam() is defined in Visual Studio 6.0 and .NET
5944 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5946 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5947 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5948 - removed compiler command line option /WX: Treats all warnings as errors
5949 - update a list of source files, included into the project
5951 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5952 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5953 changed project type to Generic Project so that can be correcly converted to VS.NET project
5955 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5957 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5959 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5961 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5962 added return 0 statements after assert() to make compiler happy
5964 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5965 added newline in the def file to keep MSC compiler satisfied
5967 * sdcc/src/z80/gen.c:
5968 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5969 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5970 - solved MSC error in function aopDump()
5972 * sdcc_vc.h: define PREFIX as "\\sdcc"
5974 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5975 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6014 2002-03-28 Johan Knol <johan AT balder>
6016 * src/SDCCval.c: fixed bug #532436
6018 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6020 Added "char *Processor" field to the port structure.
6023 Added -p option. Allows port dependent processor to be specified.
6026 Initialized the new field char *Processor field to NULL in all ports
6029 Compiler generated registers for interrupt context saving
6030 were not getting allocated.
6032 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6035 Fixed left shift. Will promote the left side of a left shift
6036 if a) left shifting more than size of operand or b) when assigned
6037 to something size > size of left side
6039 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6041 tons of changes. Register allocation has been
6042 rewritten. Added customization for the various PICs. Flow
6043 analysis is restructured. ...
6049 Added. device.c is a PIC port hack to accomodate variations
6052 2002-03-13 Michael Hope <michaelh AT vroom>
6054 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6056 2002-03-04 johanknol <johanknol AT manik>
6058 * /src/SDCCval.c: fixed
6060 const unsigned char arr[][2] = { { 0, 1 } };

6063 2002-03-04 bela <bela AT manik>
6065 * /device/include/mcs51reg.h:
6066 ds89c420 register definition update

6147 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6149 * sdcc/src/SDCCloop.c:
6150 Previous fix was not good. basic blocks that have "break" or "return" are
6151 not really partof a loop , but live ranges used in these blocks should
6152 be live thru the entire loop, so set partOfLoop but don't add them to
6155 2002-02-21 <johan AT FRIJA>
6157 * src/SDCCcse.c: fixed bug #514308
6159 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6162 Fixed BUG #519583. If a conditional block ended in a return/break
6163 statement inside a loop, it was not being considered part of the loop.
6165 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6167 2002-02-10 Karl Bongers <karl AT turbobit.com>
6170 Fixed up SDCDB debugger somewhat. Updated debugger/README
6171 with lots of comments and notes.
6173 * device/examples/test2.c:
