2533 loaded with the linker search paths (-L arguments) and the libraries
2534 to be linked with the current source (-l arguments). Changes
2535 currently will affect only the pic16 port.
2536 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2537 include path the port specific paths and port specific libraries,
2538 * gplink command now contains the $3 argument,
2539 * src/pic16/device.h,
2540 * src/pic16/device.c,: structure PIC_device is made public and

2556 Documenting changes from previous commits.
2557 * configure.in (version 1.56),
2558 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2559 when generating output files to configure the pic16 library,
2560 but now I've commented it out, since gputils aren't installed in the
2561 SF compile farm, so library won't compile
2563 * device/lib/Makefile.in (version 1.56): initially I've added in
2564 target 'all' the prerequestive 'model-pic16' so it compiled the
2565 pic16 library, but now I've commented it out for the same reasons
2567 * added targets 'model-pic16' and 'objects-pic16' to compile the
2569 * added target 'port-specific-objects-pic16' to handle the
2570 generated libraries and copy them into the build/ directory
2571 * added target 'clean-intermediate-pic16' to clean intermediate
2572 files into pic16 directory
2573 * in target 'installdirs' added line to create directory pic16 in

2770 needLinkerScript flag
2772 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2773 * src/pic/glue.c: added variable udata_section_name to
2774 override default uninitialized data segment definition for
2775 devices only with SHAREBANK memory (reported from Erik Epetrich)
2776 * (pic14emitOverlay): modified to emit a commented overlay segment
2777 directive when no overlay data exist
2778 * (picglue): modified to emit uninitialized data segment
2779 according to udata_section_name

2783 * modified _linkCmd and _asmCmd to include compiler passed
2784 arguments via -W option
2785 * src/pic16/main.c: added $l in _asmCmd, changed extension for
2786 object file from '.rel' to '.o' in port->linker structure,
2787 changed size of fptr from 2 to 3 in port structure
2789 2004-01-07 Borut Razem <borut.razem AT siol.net>
2791 * support/scripts/sdcc.nsi: update PATH
2792 * support/scripts/sdcc.ico: craeted

2805 include information about variables allocated to the overlay
2808 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2810 * as/mcs51/lkmain.c: Help about -Y option
2811 * as/mcs51/lkarea.c: Fixed gcc warnings
2813 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2815 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
2817 * support/valdiag/tests/overflow.c: added
2818 * src/SDCCast.c (decorateType),
2819 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
2820 LEFT_OP (left shift)
2822 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2824 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2825 (default behaviour).
2827 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2829 A python script to validate compiler diagnostic messages. It can be
2830 used to verify that sdcc complains about bad c source code and
2831 gives a good location of the error.
2832 * support/valdiag/Makefile,
2833 * support/valdiag/valdiag.py,
2834 * support/valdiag/tests/*
2836 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2838 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
2839 * src/SDCCsymt.c (newEnumType),

2847 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2849 * src/common.h: added ifndef/define/endif macros
2850 around the header file.
2851 Bug reported from Jesus Calvino-Fraga
2853 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2855 * sdcc.spec: updated
2856 * device/include/Makefile.in: don't install CVS directories
2857 * device/lib/Makefile.in: added removal of CVS directories after install
2858 * doc/Makefile: fixed install, added local_icons
2859 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2860 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2861 * src/ds390/gen.c (genRightShift): fixed bug #870788
2862 * src/SDCCast.c (decorateType): fixed bug #870781
2864 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2866 PIC16 port related changes:
2867 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2868 added variable stackPos,
2870 * gen.c: genCall, assignResultValue: added support for
2871 pushing/retrieving function parameters to/from stack,
2872 genFunction,genEndFunction: setup stack frame for the
2874 genAddrOf: will be changed according to bug 863624
2876 * added files genutils.c and genutils.h which contain gen*
2877 debugged and optimised functions extracted from gen.c
2879 * glue.c: added variable 'externs' which holds extern symbols,
2880 pic16emitRegularMap: is modified to properly handle relocatable
2881 symbols under the new scheme,
2882 pic16createInterruptVect: is modified
2883 pic16printPublics: is modified to emit 'global' assembler directives,
2884 added pic16_printExterns to print extern symbols,
2885 pic16glue: initializes stack/frame pointer in the beginning of
2886 the assembly output. Temporary hack, will be corrected later,
2887 because gplink yet does not support stack and SDCC does not
2888 yet support a type of crt0.o object to create the final binary.
2890 * Removed many lines that contain 8051 legacy code.
2891 * The code is finally placed under a 'code' directive.
2892 * Added port specific options.
2894 * _process_pragma: simplified since now we do not need *special*
2895 include file to define SFR registers. But a separate header
2896 will be needed. This will be developed later.
2897 * _pic16_parseOptions: added, parses port specific options:
2898 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2899 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2900 --preplace-udata-with=
2902 * _pic16_setDefaultOptions: modified to initialize section names,
2903 but hack is temporarly out of order since it needs improvement.
2904 * _pic16_genAssemblerPreamble: configuration words are emitted by
2905 their address instead of their name. This part is incomplete and
2906 supports only the 18Fxx2 devices. Other devices will emit an error
2907 during assembly since they do not contain the same set of config
2909 * _pic16_genIVT: is modified,
2911 * pcode.c: added definitions for some hardware registers that are needed
2913 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2914 All PCI entries are updated. Now LFSR is supported.
2915 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2916 * added pic16_newpCodeOpLit2 to support instructions with
2917 two literal arguments
2918 * pic16_pCode2str: corrected code that emits assembler instructions
2919 with two literal operands and those that have an access bit modifier
2920 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2921 this fixes a bug which caused some labels to be lost, when an
2922 assembler directive was added, i.e. banksel,
2923 * pic16_FixRegisterBanking: improved logic that causes the insertion
2925 * InlineFunction: functions that are called once, are not any more
2926 inlined. This can be a port option in the future,
2928 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2930 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2931 hold the corresponding uninitialized symbols,
2932 * pic16_allocProcessorRegister: registers have explicit marked the
2934 * pic16_allocInternalRegister: registers are explicit marked as
2936 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2937 processing list, so bit registers were lost,
2940 * ralloc.h: added field 'accessBank' and original symbol operand
2941 in register definition,
2942 * removed the field isMapped from register definition,
2944 ** Several functions have been removed from various sources:
2945 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2946 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2947 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2948 pic16_assignRelocatableRegisters
2950 ** others have been introduced:
2951 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2952 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2954 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2956 * support/scripts/inc2h.pl: changed definition of BIT_AT
2957 to emit 'sbit at' instead of 'bit at'. This was a request.
2959 PIC16 port related preliminary changes:
2960 * gen.c: prefixed function popRegFromString with
2961 pic16_ and all references to it corrected
2962 * pcode.c: all pic16_pc_* hardware registers prefixed
2963 with underscore (_),
2964 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2965 * ralloc.c: newReg(): when register is REG_SFR then
2966 set address to rIdx,
2967 pic16_allocProcessorRegister(): marks register wasUsed=0
2968 pic16_writeUsedRegs(): added a call to assign processor
2969 registers via pic16_assignFixedRegisters
2971 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2973 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2974 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2975 variables in unused register banks. Also the SSEG is placed
2976 wherever there is enough space for it, and IDATA can be anywhere
2977 in internal RAM. For now compile using -Wl-Y[stack_size].
2978 The mem file is different for this option as well, since it
2979 makes no sense of talking about DSEG lenght.
2981 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2983 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2984 in certain cases, e.g. when ROM assignment, patch provided
2985 from Albert den Haan.

3226 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3228 * src/SDCCast.c (decorateType): disabled a transformation I added in
3229 revision 1.188 (access to fields of a structure at an absolute address);
3230 it breaks with bitfields, extern declarations, and gcse analysis.
3231 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it

3989 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3990 fetching of the pointer
3991 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3992 copied from genNearPointerSet()
3993 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3994 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4010 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4011 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4012 type for bits was changed. It resulted in bit variables becoming
4013 global, which is not permitted in PIC 14 assembly output.

4030 A few small changes that speed up the peephole optimizer.
4034 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4036 Try to make the peephole optimizer smarter by maintaining
4037 an association between the assembly source code and the
4038 iCodes that originated them. Put this information to use
4039 with a new peephole rule condition "notVolatile" so that
4040 the rules can be aggressive yet still safe.
4045 * src/mcs51/peeph.def
4047 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4051 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4052 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4053 if the left or right operand symbols have the accuse flag set.
4055 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4057 Changed the type of the result of the ! (NOT) operator to char;
4058 previously it returned the same type as the source. This allows
4059 us to eliminate all the genFloatNot functions (all of its target
4060 implementations were very buggy) since !float can use the same

4072 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4073 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4074 during interrupts. Ensure WSAVE is located at a shared bank address.
4075 2. Fixed page selection in some places
4076 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4077 the registers name strings.
4078 4. Fixed "signed / unsigned compare" compiler warnings.
4079 5. The PIC port manages its own allocation of the general purpose
4080 registers, but makes no attempt to reuse them. As a result when
4081 compiling it soon runs out of general purpose registers. Some
4082 additional code was added to the files pcode.c and device.c to walk
4083 through the function call tree and rename the registers so that they
4093 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4100 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4102 Made bitfield a distinct type from bit so that bitfields
4103 convert as per ANSI C and bits retain their traditional
4104 boolean style behaviour. Implemented bitfield support in
4112 * src/ds390/gen.c: bit v bitfield split
4113 * src/z80/gen.c: New support for bitfields

4117 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4119 Rules 246.x, 247.x relate to bitfields, the others speed up
4120 access to xdata mapped I/O devices.
4122 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4124 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4126 Cleaned up genPackBits and genUnpackBits and added two helper

4136 Fixed bug #748310 (pointer to function type mishandled when the
4137 function name is omitted). Also fixed a SIGSEGV when a function
4138 attribute (reentrant, etc) is used on a non-function or on a
4139 function but misplaced before the parameter list.

4168 Made the constant following the "interrupt" keyword optional. If
4169 omitted, the function will not automatically be given an entry
4170 in the interrupt vector table (similar to #pragma NOIV, but
4171 less syntacticly kludgy). The interrupt number is also now
4172 range checked. Also fixed a bug in the high order bit example

4703 messages from optionsTable when a port is not configured, added
4704 support for the PIc16 port in the ports table, when executing
4705 the compiler with no port specified on command line, a default
4706 port is selected with the new macro DEFAULT_PORT which is
4707 defined in port.h, in setDefaultOptions() linkOptions is removed
4708 from initialization assignment, since now it is a set,
4709 parseCmdLine uses setParseWithComma for linkOptions, in
4710 linkEdit() linkOptions are accessed with new function indexSet()
4711 which returns the i'th item of a set variable. See SDCCset.c, in
4712 linkEdit() when calling buildCmdLine(), added linkOptions as
4713 last argument. Now users can pass arguments to gplink via the
4714 -Wl option, main() uses pic16glue() to glue up pic16 programs

4728 gpasm complaining and test the linkage with gplink, _linkCmd and
4729 _asmCmd changed to be more gplink and gpasm friendly
4730 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4731 produced an error when parsed, peep rule 12 is added to utilize
4732 movff, but it is commented out since the pCode does not support
4733 yet a command with 2 address arguments
4735 2003-05-18 <johan AT balder>
4737 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5772 * src/SDCCicode.c: fixed array add
5774 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5775 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5776 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5778 2003-01-04 <johan AT balder>
5780 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5782 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5783 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5785 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5795 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5796 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5798 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5800 * in \sdcc\as\mcs51\ changed these files in order to create an
5801 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5802 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5803 following files to include the previous two files: aslink.dsp,
5804 Makefile.aslink, Makefile.bcc, and Makefile.in.
5806 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5807 .adb instead of .cdb
5809 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5811 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5812 value from option --iram-size.
5814 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5816 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5819 2002-09-18 <wiml AT hhhh.org>
5821 * SDCClrange.h: exposed setFromRange() and setToRange()
5822 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5823 packRegsForAccUse() (bug 542397)
5824 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5825 multiple times and emitting the fetch operations more than once
5826 added aopGetUsesAcc() function to allow binary operators to
5827 fetch their operands in the correct order; made genMinus() emit
5828 compact code for X = LITERAL - Y
5830 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5831 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5832 sprintf() in line 1267.
5834 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5835 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5838 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5839 Changes to aslink (All the changes are marked with 'JCF'):
5841 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5844 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5845 area BSEG. Also moves, if possible, the DATA area down into the internal
5846 ram so more space is available.
5848 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5851 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5852 not bytes. Function summary() which creates a memory usage summary
5853 file with extension .mem. Reports of overlaping stack and small stack
5854 size. If the space for the stack is less than 16 bytes aslink trows a
5857 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5858 the 8051. Option 'y' for memory summary output file.
5860 Changes to sdcc (All the changes are marked with 'JCF'):
5862 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5864 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5865 overlaying area for it (uses RegBankUsed[4]).
5867 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5868 bank zero as used by default. By default aslink locates the stack
5869 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5870 the creation of the .mem file. Delegates the allocation of data area
5871 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5872 the begining of the stack area to aslink.
5874 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5875 glue() in SDCCglue.c creates an area for it.
5877 2002-09-03 Borut Razem <borut.razem AT siol.net>
5878 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5879 sdcc/src/pic/glue.c:
5880 introduced atexit() handler for teporay files removal in case of
5881 errors, assertions, ...
5883 2002-08-29 Borut Razem <borut.razem AT siol.net>
5884 * sdcc/support/cpp2/auto-host_vc_in.h:
5885 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5886 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5887 Maybe there is a similar problem with BORLANDC? It should be checked!
5889 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5890 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5891 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5892 was not executed, and the compiler (cl) launched a warning:
5893 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5895 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5896 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5898 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5899 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5901 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5902 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5903 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5904 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5905 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5906 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5907 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5908 - added Release configuration in VS projects
5909 - review of compiler an linker options
5910 - VC .exe files are generated in bin_vc directory, not to interfere
5911 with binaries generated from other projects (cygwin, mingw, bcc ...)
5913 * sdcc/src/yacc.dsp: added
5915 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5916 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5917 and insert the version number definitions from .version
5919 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5921 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5922 added - genarate auto-host.h using auto-host_vc_in.h as template
5925 removed from CVS, generated automatically
5927 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5928 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5930 2002-08-11 Borut Razem <borut.razem AT siol.net>
5931 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5933 2002-08-10 Borut Razem <borut.razem AT siol.net>
5934 * src/SDCCmain.c (main):
5935 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5936 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5937 The consequence was that some temporary files were not removed.
5940 unification of code in functions tempfilename() and tempfile():
5941 function tempnam() is defined in Visual Studio 6.0 and .NET
5943 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5945 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5946 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5947 - removed compiler command line option /WX: Treats all warnings as errors
5948 - update a list of source files, included into the project
5950 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5951 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5952 changed project type to Generic Project so that can be correcly converted to VS.NET project
5954 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5956 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5958 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5960 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5961 added return 0 statements after assert() to make compiler happy
5963 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5964 added newline in the def file to keep MSC compiler satisfied
5966 * sdcc/src/z80/gen.c:
5967 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5968 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5969 - solved MSC error in function aopDump()
5971 * sdcc_vc.h: define PREFIX as "\\sdcc"
5973 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5974 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6013 2002-03-28 Johan Knol <johan AT balder>
6015 * src/SDCCval.c: fixed bug #532436
6017 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6019 Added "char *Processor" field to the port structure.
6022 Added -p option. Allows port dependent processor to be specified.
6025 Initialized the new field char *Processor field to NULL in all ports
6028 Compiler generated registers for interrupt context saving
6029 were not getting allocated.
6031 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6034 Fixed left shift. Will promote the left side of a left shift
6035 if a) left shifting more than size of operand or b) when assigned
6036 to something size > size of left side
6038 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6040 tons of changes. Register allocation has been
6041 rewritten. Added customization for the various PICs. Flow
6042 analysis is restructured. ...
6048 Added. device.c is a PIC port hack to accomodate variations
6051 2002-03-13 Michael Hope <michaelh AT vroom>
6053 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6146 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6148 * sdcc/src/SDCCloop.c:
6149 Previous fix was not good. basic blocks that have "break" or "return" are
6150 not really partof a loop , but live ranges used in these blocks should
6151 be live thru the entire loop, so set partOfLoop but don't add them to
6154 2002-02-21 <johan AT FRIJA>
6156 * src/SDCCcse.c: fixed bug #514308
6158 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6161 Fixed BUG #519583. If a conditional block ended in a return/break
6162 statement inside a loop, it was not being considered part of the loop.
6164 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6166 2002-02-10 Karl Bongers <karl AT turbobit.com>
6169 Fixed up SDCDB debugger somewhat. Updated debugger/README
6170 with lots of comments and notes.
6172 * device/examples/test2.c:
