2626 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2628 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2629 loaded with the linker search paths (-L arguments) and the libraries
2630 to be linked with the current source (-l arguments). Changes
2631 currently will affect only the pic16 port.
2632 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2633 include path the port specific paths and port specific libraries,
2634 * gplink command now contains the $3 argument,
2635 * src/pic16/device.h,
2636 * src/pic16/device.c,: structure PIC_device is made public and

2652 Documenting changes from previous commits.
2653 * configure.in (version 1.56),
2654 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2655 when generating output files to configure the pic16 library,
2656 but now I've commented it out, since gputils aren't installed in the
2657 SF compile farm, so library won't compile
2659 * device/lib/Makefile.in (version 1.56): initially I've added in
2660 target 'all' the prerequestive 'model-pic16' so it compiled the
2661 pic16 library, but now I've commented it out for the same reasons
2663 * added targets 'model-pic16' and 'objects-pic16' to compile the
2665 * added target 'port-specific-objects-pic16' to handle the
2666 generated libraries and copy them into the build/ directory
2667 * added target 'clean-intermediate-pic16' to clean intermediate
2668 files into pic16 directory
2669 * in target 'installdirs' added line to create directory pic16 in
2670 the installation path
2672 * device/include/Makefile.in (version 1.11): in target 'install'
2673 added lines to copy all header files to installation path,
2674 * in target 'installdirs' added line create directory for pic16
2675 headers in the installation path

2691 option so that it actually works. Made it specific to the z80, since
2692 the gbz80 doesn't have these kinds of I/O ports.
2694 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2696 * device/include/z180.h,

2720 via literal number. The symbol is placed in the corresponding
2721 position of the data ram
2722 * (pic16_dump_section): relocatable and absolute uninitialized
2723 data are now emitted in sorted order to reduce section naming,
2724 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2725 weren't marked as being in the access bank,
2727 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2729 Added portion of GNU PIC Library under the directory
2730 device/include/pic16 and device/lib/pic16. These files
2731 contain the declarations of SFRs for the PIC18Fxx2 devices.
2732 The directory is initialized via configure from toplevel.

2761 * doc/sdccman.lyx: Moved and added some sections, small changes
2762 all over. Telling LaTeX to be less strict with word spacing
2763 to better keep the right margin. Changed some notes about
2764 maintainance of the ports in section 3.2.1 - is it OK like this?
2766 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2768 SDCC source changes:
2769 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2901 include information about variables allocated to the overlay
2904 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2906 * as/mcs51/lkmain.c: Help about -Y option

2918 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2920 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2921 (default behaviour).
2923 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2925 A python script to validate compiler diagnostic messages. It can be
2926 used to verify that sdcc complains about bad c source code and
2927 gives a good location of the error.
2928 * support/valdiag/Makefile,
2929 * support/valdiag/valdiag.py,
2930 * support/valdiag/tests/*
2932 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2945 * src/common.h: added ifndef/define/endif macros
2946 around the header file.
2947 Bug reported from Jesus Calvino-Fraga
2949 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2951 * sdcc.spec: updated
2952 * device/include/Makefile.in: don't install CVS directories
2953 * device/lib/Makefile.in: added removal of CVS directories after install
2954 * doc/Makefile: fixed install, added local_icons
2955 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2956 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2957 * src/ds390/gen.c (genRightShift): fixed bug #870788
2958 * src/SDCCast.c (decorateType): fixed bug #870781
2960 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2962 PIC16 port related changes:
2963 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2964 added variable stackPos,
2966 * gen.c: genCall, assignResultValue: added support for
2967 pushing/retrieving function parameters to/from stack,
2968 genFunction,genEndFunction: setup stack frame for the
2970 genAddrOf: will be changed according to bug 863624
2972 * added files genutils.c and genutils.h which contain gen*
2973 debugged and optimised functions extracted from gen.c
2975 * glue.c: added variable 'externs' which holds extern symbols,
2976 pic16emitRegularMap: is modified to properly handle relocatable
2977 symbols under the new scheme,
2978 pic16createInterruptVect: is modified
2979 pic16printPublics: is modified to emit 'global' assembler directives,
2980 added pic16_printExterns to print extern symbols,
2981 pic16glue: initializes stack/frame pointer in the beginning of
2982 the assembly output. Temporary hack, will be corrected later,
2983 because gplink yet does not support stack and SDCC does not
2984 yet support a type of crt0.o object to create the final binary.
2986 * Removed many lines that contain 8051 legacy code.
2987 * The code is finally placed under a 'code' directive.
2988 * Added port specific options.
2990 * _process_pragma: simplified since now we do not need *special*
2991 include file to define SFR registers. But a separate header
2992 will be needed. This will be developed later.
2993 * _pic16_parseOptions: added, parses port specific options:
2994 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2995 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2996 --preplace-udata-with=
2998 * _pic16_setDefaultOptions: modified to initialize section names,
2999 but hack is temporarly out of order since it needs improvement.
3000 * _pic16_genAssemblerPreamble: configuration words are emitted by
3001 their address instead of their name. This part is incomplete and
3002 supports only the 18Fxx2 devices. Other devices will emit an error
3003 during assembly since they do not contain the same set of config
3005 * _pic16_genIVT: is modified,
3007 * pcode.c: added definitions for some hardware registers that are needed
3009 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3010 All PCI entries are updated. Now LFSR is supported.
3011 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3012 * added pic16_newpCodeOpLit2 to support instructions with
3013 two literal arguments
3014 * pic16_pCode2str: corrected code that emits assembler instructions
3015 with two literal operands and those that have an access bit modifier
3016 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3017 this fixes a bug which caused some labels to be lost, when an
3018 assembler directive was added, i.e. banksel,
3019 * pic16_FixRegisterBanking: improved logic that causes the insertion
3021 * InlineFunction: functions that are called once, are not any more
3022 inlined. This can be a port option in the future,
3024 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3026 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3027 hold the corresponding uninitialized symbols,
3028 * pic16_allocProcessorRegister: registers have explicit marked the
3030 * pic16_allocInternalRegister: registers are explicit marked as
3032 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3033 processing list, so bit registers were lost,
3036 * ralloc.h: added field 'accessBank' and original symbol operand
3037 in register definition,
3038 * removed the field isMapped from register definition,
3040 ** Several functions have been removed from various sources:
3041 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3042 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3043 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3044 pic16_assignRelocatableRegisters
3046 ** others have been introduced:
3047 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3048 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3050 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3052 * support/scripts/inc2h.pl: changed definition of BIT_AT
3053 to emit 'sbit at' instead of 'bit at'. This was a request.
3055 PIC16 port related preliminary changes:
3056 * gen.c: prefixed function popRegFromString with
3057 pic16_ and all references to it corrected
3058 * pcode.c: all pic16_pc_* hardware registers prefixed
3059 with underscore (_),
3060 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3061 * ralloc.c: newReg(): when register is REG_SFR then
3062 set address to rIdx,
3063 pic16_allocProcessorRegister(): marks register wasUsed=0
3064 pic16_writeUsedRegs(): added a call to assign processor
3065 registers via pic16_assignFixedRegisters
3067 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3069 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3070 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3071 variables in unused register banks. Also the SSEG is placed
3072 wherever there is enough space for it, and IDATA can be anywhere
3073 in internal RAM. For now compile using -Wl-Y[stack_size].
3074 The mem file is different for this option as well, since it
3075 makes no sense of talking about DSEG lenght.
3077 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3079 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3080 in certain cases, e.g. when ROM assignment, patch provided
3081 from Albert den Haan.
3083 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3226 * src/mcs51/peephole.def,
3227 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3228 (allows non-interrupt and interrupt code to safely compete for a resource

4106 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4107 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4126 A few small changes that speed up the peephole optimizer.
4130 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4132 Try to make the peephole optimizer smarter by maintaining
4133 an association between the assembly source code and the
4134 iCodes that originated them. Put this information to use
4135 with a new peephole rule condition "notVolatile" so that
4136 the rules can be aggressive yet still safe.
4141 * src/mcs51/peeph.def
4143 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4147 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4148 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4149 if the left or right operand symbols have the accuse flag set.
4151 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4153 Changed the type of the result of the ! (NOT) operator to char;
4154 previously it returned the same type as the source. This allows
4155 us to eliminate all the genFloatNot functions (all of its target
4156 implementations were very buggy) since !float can use the same
4159 * src/SDCCicode.c (ast2iCode): ! returns char

4168 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4169 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4170 during interrupts. Ensure WSAVE is located at a shared bank address.
4171 2. Fixed page selection in some places
4172 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4173 the registers name strings.
4174 4. Fixed "signed / unsigned compare" compiler warnings.
4175 5. The PIC port manages its own allocation of the general purpose
4176 registers, but makes no attempt to reuse them. As a result when
4177 compiling it soon runs out of general purpose registers. Some
4178 additional code was added to the files pcode.c and device.c to walk
4179 through the function call tree and rename the registers so that they
4189 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4196 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4198 Made bitfield a distinct type from bit so that bitfields
4199 convert as per ANSI C and bits retain their traditional
4200 boolean style behaviour. Implemented bitfield support in
4208 * src/ds390/gen.c: bit v bitfield split
4209 * src/z80/gen.c: New support for bitfields
4210 * support/regression/tests/bitfields.c: reenabled z80,
4213 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4215 Rules 246.x, 247.x relate to bitfields, the others speed up
4216 access to xdata mapped I/O devices.
4218 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4220 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4222 Cleaned up genPackBits and genUnpackBits and added two helper

4232 Fixed bug #748310 (pointer to function type mishandled when the
4233 function name is omitted). Also fixed a SIGSEGV when a function
4234 attribute (reentrant, etc) is used on a non-function or on a
4235 function but misplaced before the parameter list.

4262 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4264 Made the constant following the "interrupt" keyword optional. If
4265 omitted, the function will not automatically be given an entry
4266 in the interrupt vector table (similar to #pragma NOIV, but
4267 less syntacticly kludgy). The interrupt number is also now
4268 range checked. Also fixed a bug in the high order bit example
4275 * support/Util/SDCCerr.c
4276 * support/Util/SDCCerr.h

4801 the compiler with no port specified on command line, a default
4802 port is selected with the new macro DEFAULT_PORT which is
4803 defined in port.h, in setDefaultOptions() linkOptions is removed
4804 from initialization assignment, since now it is a set,
4805 parseCmdLine uses setParseWithComma for linkOptions, in

5874 2003-01-04 <johan AT balder>
5876 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5878 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5879 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5881 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5891 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5892 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5894 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5896 * in \sdcc\as\mcs51\ changed these files in order to create an
5897 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5898 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5899 following files to include the previous two files: aslink.dsp,
5900 Makefile.aslink, Makefile.bcc, and Makefile.in.
5902 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5903 .adb instead of .cdb
5905 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5907 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5908 value from option --iram-size.
5910 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5912 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5915 2002-09-18 <wiml AT hhhh.org>
5917 * SDCClrange.h: exposed setFromRange() and setToRange()
5918 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5919 packRegsForAccUse() (bug 542397)
5920 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5921 multiple times and emitting the fetch operations more than once
5922 added aopGetUsesAcc() function to allow binary operators to
5923 fetch their operands in the correct order; made genMinus() emit
5924 compact code for X = LITERAL - Y
5926 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5927 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5928 sprintf() in line 1267.
5930 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5931 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5934 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5935 Changes to aslink (All the changes are marked with 'JCF'):
5937 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5940 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5941 area BSEG. Also moves, if possible, the DATA area down into the internal
5942 ram so more space is available.
5944 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5947 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5948 not bytes. Function summary() which creates a memory usage summary
5949 file with extension .mem. Reports of overlaping stack and small stack
5950 size. If the space for the stack is less than 16 bytes aslink trows a
5953 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5954 the 8051. Option 'y' for memory summary output file.
5956 Changes to sdcc (All the changes are marked with 'JCF'):
5958 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5960 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5961 overlaying area for it (uses RegBankUsed[4]).
5963 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5964 bank zero as used by default. By default aslink locates the stack
5965 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5966 the creation of the .mem file. Delegates the allocation of data area
5967 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5968 the begining of the stack area to aslink.
5970 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5971 glue() in SDCCglue.c creates an area for it.
5973 2002-09-03 Borut Razem <borut.razem AT siol.net>
5974 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5975 sdcc/src/pic/glue.c:
5976 introduced atexit() handler for teporay files removal in case of
5977 errors, assertions, ...
5979 2002-08-29 Borut Razem <borut.razem AT siol.net>
5980 * sdcc/support/cpp2/auto-host_vc_in.h:
5981 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5982 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5983 Maybe there is a similar problem with BORLANDC? It should be checked!
5985 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5986 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5987 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5988 was not executed, and the compiler (cl) launched a warning:
5989 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5991 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5992 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5994 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5995 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5997 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5998 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5999 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6000 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6001 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6002 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6003 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6004 - added Release configuration in VS projects
6005 - review of compiler an linker options
6006 - VC .exe files are generated in bin_vc directory, not to interfere
6007 with binaries generated from other projects (cygwin, mingw, bcc ...)
6009 * sdcc/src/yacc.dsp: added
6011 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6012 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6013 and insert the version number definitions from .version
6015 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6017 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6018 added - genarate auto-host.h using auto-host_vc_in.h as template
6021 removed from CVS, generated automatically
6023 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6024 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6026 2002-08-11 Borut Razem <borut.razem AT siol.net>
6027 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6029 2002-08-10 Borut Razem <borut.razem AT siol.net>
6030 * src/SDCCmain.c (main):
6031 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6032 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6033 The consequence was that some temporary files were not removed.
6036 unification of code in functions tempfilename() and tempfile():
6037 function tempnam() is defined in Visual Studio 6.0 and .NET
6039 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6041 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6042 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6043 - removed compiler command line option /WX: Treats all warnings as errors
6044 - update a list of source files, included into the project
6046 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6047 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6048 changed project type to Generic Project so that can be correcly converted to VS.NET project
6050 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6052 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6054 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6056 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6057 added return 0 statements after assert() to make compiler happy
6059 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6060 added newline in the def file to keep MSC compiler satisfied
6062 * sdcc/src/z80/gen.c:
6063 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6064 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6065 - solved MSC error in function aopDump()
6067 * sdcc_vc.h: define PREFIX as "\\sdcc"
6069 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6070 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6072 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6073 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6074 - Rewrote the register banking algorithm.
6075 - Added pCode live-range analysis to registers (for now, only non-used and
6076 singly-used registers optimized away)
6078 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6080 * 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.
6082 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6083 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6085 2002-04-22 Michael Hope <michaelh AT vroom>

6101 * src/z80/peeph.def: Added transpose redundent load rule.
6103 * src/z80/main.c: Added force callee saves for jaune.
6105 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6107 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6109 2002-03-28 Johan Knol <johan AT balder>
6111 * src/SDCCval.c: fixed bug #532436
6113 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6115 Added "char *Processor" field to the port structure.
6118 Added -p option. Allows port dependent processor to be specified.
6121 Initialized the new field char *Processor field to NULL in all ports
6124 Compiler generated registers for interrupt context saving
6125 were not getting allocated.
6127 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6130 Fixed left shift. Will promote the left side of a left shift
6131 if a) left shifting more than size of operand or b) when assigned
6132 to something size > size of left side
6134 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6136 tons of changes. Register allocation has been
6137 rewritten. Added customization for the various PICs. Flow
6138 analysis is restructured. ...
6144 Added. device.c is a PIC port hack to accomodate variations
6147 2002-03-13 Michael Hope <michaelh AT vroom>
6149 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6151 2002-03-04 johanknol <johanknol AT manik>
6153 * /src/SDCCval.c: fixed
6155 const unsigned char arr[][2] = { { 0, 1 } };
