2620 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2622 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2623 loaded with the linker search paths (-L arguments) and the libraries
2624 to be linked with the current source (-l arguments). Changes
2625 currently will affect only the pic16 port.
2626 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2627 include path the port specific paths and port specific libraries,
2628 * gplink command now contains the $3 argument,
2629 * src/pic16/device.h,
2630 * src/pic16/device.c,: structure PIC_device is made public and
2631 renamed to PIC16_device, the same for variable Pics which is renamed

2646 Documenting changes from previous commits.
2647 * configure.in (version 1.56),
2648 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2649 when generating output files to configure the pic16 library,
2650 but now I've commented it out, since gputils aren't installed in the
2651 SF compile farm, so library won't compile
2653 * device/lib/Makefile.in (version 1.56): initially I've added in
2654 target 'all' the prerequestive 'model-pic16' so it compiled the
2655 pic16 library, but now I've commented it out for the same reasons
2657 * added targets 'model-pic16' and 'objects-pic16' to compile the
2659 * added target 'port-specific-objects-pic16' to handle the
2660 generated libraries and copy them into the build/ directory
2661 * added target 'clean-intermediate-pic16' to clean intermediate
2662 files into pic16 directory
2663 * in target 'installdirs' added line to create directory pic16 in
2664 the installation path

2667 added lines to copy all header files to installation path,
2668 * in target 'installdirs' added line create directory for pic16
2669 headers in the installation path

2684 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2685 option so that it actually works. Made it specific to the z80, since
2686 the gbz80 doesn't have these kinds of I/O ports.
2688 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2690 * device/include/z180.h,

2714 via literal number. The symbol is placed in the corresponding
2715 position of the data ram
2716 * (pic16_dump_section): relocatable and absolute uninitialized
2717 data are now emitted in sorted order to reduce section naming,
2718 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2719 weren't marked as being in the access bank,
2721 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2723 Added portion of GNU PIC Library under the directory
2724 device/include/pic16 and device/lib/pic16. These files
2725 contain the declarations of SFRs for the PIC18Fxx2 devices.
2726 The directory is initialized via configure from toplevel.

2737 2004-01-12 Borut Razem <borut.razem AT siol.net>
2739 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
2740 doc/sdccman.lyx: upper case pragmas are deprecated
2742 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

2755 * doc/sdccman.lyx: Moved and added some sections, small changes
2756 all over. Telling LaTeX to be less strict with word spacing
2757 to better keep the right margin. Changed some notes about
2758 maintainance of the ports in section 3.2.1 - is it OK like this?
2760 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2762 SDCC source changes:
2763 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2797 UPPER for immediate operands,
2798 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2800 * src/pic16/peeph.def: all peepholes with movff are commented out,
2801 because there is a problem in the pcode peep optimizer,
2802 * src/pic16/ralloc.c: the register allocator can now reuse local

2895 include information about variables allocated to the overlay
2898 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2900 * as/mcs51/lkmain.c: Help about -Y option

2912 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2914 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2915 (default behaviour).
2917 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2919 A python script to validate compiler diagnostic messages. It can be
2920 used to verify that sdcc complains about bad c source code and
2921 gives a good location of the error.
2922 * support/valdiag/Makefile,
2923 * support/valdiag/valdiag.py,
2924 * support/valdiag/tests/*
2926 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2939 * src/common.h: added ifndef/define/endif macros
2940 around the header file.
2941 Bug reported from Jesus Calvino-Fraga
2943 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2945 * sdcc.spec: updated
2946 * device/include/Makefile.in: don't install CVS directories
2947 * device/lib/Makefile.in: added removal of CVS directories after install
2948 * doc/Makefile: fixed install, added local_icons
2949 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2950 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2951 * src/ds390/gen.c (genRightShift): fixed bug #870788
2952 * src/SDCCast.c (decorateType): fixed bug #870781
2954 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2956 PIC16 port related changes:
2957 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2958 added variable stackPos,
2960 * gen.c: genCall, assignResultValue: added support for
2961 pushing/retrieving function parameters to/from stack,
2962 genFunction,genEndFunction: setup stack frame for the
2964 genAddrOf: will be changed according to bug 863624
2966 * added files genutils.c and genutils.h which contain gen*
2967 debugged and optimised functions extracted from gen.c
2969 * glue.c: added variable 'externs' which holds extern symbols,
2970 pic16emitRegularMap: is modified to properly handle relocatable
2971 symbols under the new scheme,
2972 pic16createInterruptVect: is modified
2973 pic16printPublics: is modified to emit 'global' assembler directives,
2974 added pic16_printExterns to print extern symbols,
2975 pic16glue: initializes stack/frame pointer in the beginning of
2976 the assembly output. Temporary hack, will be corrected later,
2977 because gplink yet does not support stack and SDCC does not
2978 yet support a type of crt0.o object to create the final binary.
2980 * Removed many lines that contain 8051 legacy code.
2981 * The code is finally placed under a 'code' directive.
2982 * Added port specific options.
2984 * _process_pragma: simplified since now we do not need *special*
2985 include file to define SFR registers. But a separate header
2986 will be needed. This will be developed later.
2987 * _pic16_parseOptions: added, parses port specific options:
2988 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2989 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2990 --preplace-udata-with=
2992 * _pic16_setDefaultOptions: modified to initialize section names,
2993 but hack is temporarly out of order since it needs improvement.
2994 * _pic16_genAssemblerPreamble: configuration words are emitted by
2995 their address instead of their name. This part is incomplete and
2996 supports only the 18Fxx2 devices. Other devices will emit an error
2997 during assembly since they do not contain the same set of config
2999 * _pic16_genIVT: is modified,
3001 * pcode.c: added definitions for some hardware registers that are needed
3003 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3004 All PCI entries are updated. Now LFSR is supported.
3005 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3006 * added pic16_newpCodeOpLit2 to support instructions with
3007 two literal arguments
3008 * pic16_pCode2str: corrected code that emits assembler instructions
3009 with two literal operands and those that have an access bit modifier
3010 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3011 this fixes a bug which caused some labels to be lost, when an
3012 assembler directive was added, i.e. banksel,
3013 * pic16_FixRegisterBanking: improved logic that causes the insertion
3015 * InlineFunction: functions that are called once, are not any more
3016 inlined. This can be a port option in the future,
3018 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3020 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3021 hold the corresponding uninitialized symbols,
3022 * pic16_allocProcessorRegister: registers have explicit marked the
3024 * pic16_allocInternalRegister: registers are explicit marked as
3026 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3027 processing list, so bit registers were lost,
3030 * ralloc.h: added field 'accessBank' and original symbol operand
3031 in register definition,
3032 * removed the field isMapped from register definition,
3034 ** Several functions have been removed from various sources:
3035 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3036 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3037 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3038 pic16_assignRelocatableRegisters
3040 ** others have been introduced:
3041 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3042 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3044 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3046 * support/scripts/inc2h.pl: changed definition of BIT_AT
3047 to emit 'sbit at' instead of 'bit at'. This was a request.
3049 PIC16 port related preliminary changes:
3050 * gen.c: prefixed function popRegFromString with
3051 pic16_ and all references to it corrected
3052 * pcode.c: all pic16_pc_* hardware registers prefixed
3053 with underscore (_),
3054 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3055 * ralloc.c: newReg(): when register is REG_SFR then
3056 set address to rIdx,
3057 pic16_allocProcessorRegister(): marks register wasUsed=0
3058 pic16_writeUsedRegs(): added a call to assign processor
3059 registers via pic16_assignFixedRegisters
3061 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3063 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3064 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3065 variables in unused register banks. Also the SSEG is placed
3066 wherever there is enough space for it, and IDATA can be anywhere
3067 in internal RAM. For now compile using -Wl-Y[stack_size].
3068 The mem file is different for this option as well, since it
3069 makes no sense of talking about DSEG lenght.
3071 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3073 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3074 in certain cases, e.g. when ROM assignment, patch provided
3075 from Albert den Haan.
3077 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3220 * src/mcs51/peephole.def,
3221 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3222 (allows non-interrupt and interrupt code to safely compete for a resource

4100 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4101 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4102 type for bits was changed. It resulted in bit variables becoming

4120 A few small changes that speed up the peephole optimizer.
4124 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4126 Try to make the peephole optimizer smarter by maintaining
4127 an association between the assembly source code and the
4128 iCodes that originated them. Put this information to use
4129 with a new peephole rule condition "notVolatile" so that
4130 the rules can be aggressive yet still safe.
4135 * src/mcs51/peeph.def
4137 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4141 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4142 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4143 if the left or right operand symbols have the accuse flag set.
4145 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4147 Changed the type of the result of the ! (NOT) operator to char;
4148 previously it returned the same type as the source. This allows
4149 us to eliminate all the genFloatNot functions (all of its target
4150 implementations were very buggy) since !float can use the same
4153 * src/SDCCicode.c (ast2iCode): ! returns char

4162 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4163 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4164 during interrupts. Ensure WSAVE is located at a shared bank address.
4165 2. Fixed page selection in some places
4166 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4167 the registers name strings.
4168 4. Fixed "signed / unsigned compare" compiler warnings.
4169 5. The PIC port manages its own allocation of the general purpose
4170 registers, but makes no attempt to reuse them. As a result when
4171 compiling it soon runs out of general purpose registers. Some
4172 additional code was added to the files pcode.c and device.c to walk
4173 through the function call tree and rename the registers so that they
4183 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4190 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4192 Made bitfield a distinct type from bit so that bitfields
4193 convert as per ANSI C and bits retain their traditional
4194 boolean style behaviour. Implemented bitfield support in
4202 * src/ds390/gen.c: bit v bitfield split
4203 * src/z80/gen.c: New support for bitfields
4204 * support/regression/tests/bitfields.c: reenabled z80,
4207 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4209 Rules 246.x, 247.x relate to bitfields, the others speed up
4210 access to xdata mapped I/O devices.
4212 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4214 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4216 Cleaned up genPackBits and genUnpackBits and added two helper

4226 Fixed bug #748310 (pointer to function type mishandled when the
4227 function name is omitted). Also fixed a SIGSEGV when a function
4228 attribute (reentrant, etc) is used on a non-function or on a
4229 function but misplaced before the parameter list.

4258 Made the constant following the "interrupt" keyword optional. If
4259 omitted, the function will not automatically be given an entry
4260 in the interrupt vector table (similar to #pragma NOIV, but
4261 less syntacticly kludgy). The interrupt number is also now
4262 range checked. Also fixed a bug in the high order bit example
4269 * support/Util/SDCCerr.c
4270 * support/Util/SDCCerr.h
4273 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

4283 unsigned, but are signed by default
4284 * src/SDCCval.c (constVal): rearranged
4285 * src/SDCCval.c (valMod): preliminary fix
4286 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4329 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4330 * src/SDCCval.c (valDiv, valMod): fixed signdness
4331 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4332 signedness of modulo, left and right shift

4795 the compiler with no port specified on command line, a default
4796 port is selected with the new macro DEFAULT_PORT which is
4797 defined in port.h, in setDefaultOptions() linkOptions is removed
4798 from initialization assignment, since now it is a set,
4799 parseCmdLine uses setParseWithComma for linkOptions, in

5868 2003-01-04 <johan AT balder>
5870 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5872 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5885 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5886 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5888 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5890 * in \sdcc\as\mcs51\ changed these files in order to create an
5891 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5892 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5893 following files to include the previous two files: aslink.dsp,
5894 Makefile.aslink, Makefile.bcc, and Makefile.in.
5896 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5897 .adb instead of .cdb
5899 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5901 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5902 value from option --iram-size.
5904 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5906 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5909 2002-09-18 <wiml AT hhhh.org>
5911 * SDCClrange.h: exposed setFromRange() and setToRange()
5912 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5913 packRegsForAccUse() (bug 542397)
5914 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5915 multiple times and emitting the fetch operations more than once
5916 added aopGetUsesAcc() function to allow binary operators to
5917 fetch their operands in the correct order; made genMinus() emit
5918 compact code for X = LITERAL - Y
5920 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5921 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5922 sprintf() in line 1267.
5924 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5925 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5928 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5929 Changes to aslink (All the changes are marked with 'JCF'):
5931 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5934 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5935 area BSEG. Also moves, if possible, the DATA area down into the internal
5936 ram so more space is available.
5938 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5941 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5942 not bytes. Function summary() which creates a memory usage summary
5943 file with extension .mem. Reports of overlaping stack and small stack
5944 size. If the space for the stack is less than 16 bytes aslink trows a
5947 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5948 the 8051. Option 'y' for memory summary output file.
5950 Changes to sdcc (All the changes are marked with 'JCF'):
5952 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5954 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5955 overlaying area for it (uses RegBankUsed[4]).
5957 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5958 bank zero as used by default. By default aslink locates the stack
5959 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5960 the creation of the .mem file. Delegates the allocation of data area
5961 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5962 the begining of the stack area to aslink.
5964 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5965 glue() in SDCCglue.c creates an area for it.
5967 2002-09-03 Borut Razem <borut.razem AT siol.net>
5968 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5969 sdcc/src/pic/glue.c:
5970 introduced atexit() handler for teporay files removal in case of
5971 errors, assertions, ...
5973 2002-08-29 Borut Razem <borut.razem AT siol.net>
5974 * sdcc/support/cpp2/auto-host_vc_in.h:
5975 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5976 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5977 Maybe there is a similar problem with BORLANDC? It should be checked!
5979 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5980 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5981 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5982 was not executed, and the compiler (cl) launched a warning:
5983 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5985 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5986 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5988 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5989 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5991 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5992 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5993 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5994 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5995 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5996 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5997 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5998 - added Release configuration in VS projects
5999 - review of compiler an linker options
6000 - VC .exe files are generated in bin_vc directory, not to interfere
6001 with binaries generated from other projects (cygwin, mingw, bcc ...)
6003 * sdcc/src/yacc.dsp: added
6005 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6006 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6007 and insert the version number definitions from .version
6009 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6011 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6012 added - genarate auto-host.h using auto-host_vc_in.h as template
6015 removed from CVS, generated automatically
6017 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6018 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6020 2002-08-11 Borut Razem <borut.razem AT siol.net>
6021 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6023 2002-08-10 Borut Razem <borut.razem AT siol.net>
6024 * src/SDCCmain.c (main):
6025 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6026 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6027 The consequence was that some temporary files were not removed.
6030 unification of code in functions tempfilename() and tempfile():
6031 function tempnam() is defined in Visual Studio 6.0 and .NET
6033 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6035 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6036 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6037 - removed compiler command line option /WX: Treats all warnings as errors
6038 - update a list of source files, included into the project
6040 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6041 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6042 changed project type to Generic Project so that can be correcly converted to VS.NET project
6044 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6046 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6048 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6050 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6051 added return 0 statements after assert() to make compiler happy
6053 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6054 added newline in the def file to keep MSC compiler satisfied
6056 * sdcc/src/z80/gen.c:
6057 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6058 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6059 - solved MSC error in function aopDump()
6061 * sdcc_vc.h: define PREFIX as "\\sdcc"
6063 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6064 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6067 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6068 - Rewrote the register banking algorithm.
6069 - Added pCode live-range analysis to registers (for now, only non-used and
6070 singly-used registers optimized away)
6072 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6074 * 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.

6103 2002-03-28 Johan Knol <johan AT balder>
6105 * src/SDCCval.c: fixed bug #532436
6107 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6109 Added "char *Processor" field to the port structure.
6112 Added -p option. Allows port dependent processor to be specified.
6115 Initialized the new field char *Processor field to NULL in all ports
6118 Compiler generated registers for interrupt context saving
6119 were not getting allocated.
6121 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6124 Fixed left shift. Will promote the left side of a left shift
6125 if a) left shifting more than size of operand or b) when assigned
6126 to something size > size of left side
6128 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6130 tons of changes. Register allocation has been
6131 rewritten. Added customization for the various PICs. Flow
6132 analysis is restructured. ...
6138 Added. device.c is a PIC port hack to accomodate variations
6141 2002-03-13 Michael Hope <michaelh AT vroom>
6143 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6145 2002-03-04 johanknol <johanknol AT manik>
6147 * /src/SDCCval.c: fixed
6149 const unsigned char arr[][2] = { { 0, 1 } };
