2543 loaded with the linker search paths (-L arguments) and the libraries
2544 to be linked with the current source (-l arguments). Changes
2545 currently will affect only the pic16 port.
2546 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2547 include path the port specific paths and port specific libraries,
2548 * gplink command now contains the $3 argument,
2549 * src/pic16/device.h,
2550 * src/pic16/device.c,: structure PIC_device is made public and
2551 renamed to PIC16_device, the same for variable Pics which is renamed

2566 Documenting changes from previous commits.
2567 * configure.in (version 1.56),
2568 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2569 when generating output files to configure the pic16 library,
2570 but now I've commented it out, since gputils aren't installed in the
2571 SF compile farm, so library won't compile
2573 * device/lib/Makefile.in (version 1.56): initially I've added in
2574 target 'all' the prerequestive 'model-pic16' so it compiled the
2575 pic16 library, but now I've commented it out for the same reasons
2577 * added targets 'model-pic16' and 'objects-pic16' to compile the
2579 * added target 'port-specific-objects-pic16' to handle the
2580 generated libraries and copy them into the build/ directory
2581 * added target 'clean-intermediate-pic16' to clean intermediate
2582 files into pic16 directory
2583 * in target 'installdirs' added line to create directory pic16 in

2605 option so that it actually works. Made it specific to the z80, since
2606 the gbz80 doesn't have these kinds of I/O ports.
2608 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2610 * device/include/z180.h,

2828 * src/SDCCast.c (decorateType),
2829 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
2830 LEFT_OP (left shift)
2832 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2834 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2835 (default behaviour).
2837 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2839 A python script to validate compiler diagnostic messages. It can be
2840 used to verify that sdcc complains about bad c source code and
2841 gives a good location of the error.
2842 * support/valdiag/Makefile,
2843 * support/valdiag/valdiag.py,
2844 * support/valdiag/tests/*
2846 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2861 Bug reported from Jesus Calvino-Fraga
2863 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2865 * sdcc.spec: updated
2866 * device/include/Makefile.in: don't install CVS directories
2867 * device/lib/Makefile.in: added removal of CVS directories after install
2868 * doc/Makefile: fixed install, added local_icons
2869 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2870 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2871 * src/ds390/gen.c (genRightShift): fixed bug #870788
2872 * src/SDCCast.c (decorateType): fixed bug #870781
2874 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2876 PIC16 port related changes:
2877 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2878 added variable stackPos,
2880 * gen.c: genCall, assignResultValue: added support for
2881 pushing/retrieving function parameters to/from stack,
2882 genFunction,genEndFunction: setup stack frame for the
2884 genAddrOf: will be changed according to bug 863624
2886 * added files genutils.c and genutils.h which contain gen*
2887 debugged and optimised functions extracted from gen.c
2889 * glue.c: added variable 'externs' which holds extern symbols,
2890 pic16emitRegularMap: is modified to properly handle relocatable
2891 symbols under the new scheme,
2892 pic16createInterruptVect: is modified
2893 pic16printPublics: is modified to emit 'global' assembler directives,
2894 added pic16_printExterns to print extern symbols,
2895 pic16glue: initializes stack/frame pointer in the beginning of
2896 the assembly output. Temporary hack, will be corrected later,
2897 because gplink yet does not support stack and SDCC does not
2898 yet support a type of crt0.o object to create the final binary.
2900 * Removed many lines that contain 8051 legacy code.
2901 * The code is finally placed under a 'code' directive.
2902 * Added port specific options.
2904 * _process_pragma: simplified since now we do not need *special*
2905 include file to define SFR registers. But a separate header
2906 will be needed. This will be developed later.
2907 * _pic16_parseOptions: added, parses port specific options:
2908 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2909 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2910 --preplace-udata-with=
2912 * _pic16_setDefaultOptions: modified to initialize section names,
2913 but hack is temporarly out of order since it needs improvement.
2914 * _pic16_genAssemblerPreamble: configuration words are emitted by
2915 their address instead of their name. This part is incomplete and
2916 supports only the 18Fxx2 devices. Other devices will emit an error
2917 during assembly since they do not contain the same set of config
2919 * _pic16_genIVT: is modified,
2921 * pcode.c: added definitions for some hardware registers that are needed
2923 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2924 All PCI entries are updated. Now LFSR is supported.
2925 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2926 * added pic16_newpCodeOpLit2 to support instructions with
2927 two literal arguments
2928 * pic16_pCode2str: corrected code that emits assembler instructions
2929 with two literal operands and those that have an access bit modifier
2930 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2931 this fixes a bug which caused some labels to be lost, when an
2932 assembler directive was added, i.e. banksel,
2933 * pic16_FixRegisterBanking: improved logic that causes the insertion
2935 * InlineFunction: functions that are called once, are not any more
2936 inlined. This can be a port option in the future,
2938 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2940 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2941 hold the corresponding uninitialized symbols,
2942 * pic16_allocProcessorRegister: registers have explicit marked the
2944 * pic16_allocInternalRegister: registers are explicit marked as
2946 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2947 processing list, so bit registers were lost,
2950 * ralloc.h: added field 'accessBank' and original symbol operand
2951 in register definition,
2952 * removed the field isMapped from register definition,
2954 ** Several functions have been removed from various sources:
2955 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2956 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2957 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2958 pic16_assignRelocatableRegisters
2960 ** others have been introduced:
2961 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2962 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2964 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2966 * support/scripts/inc2h.pl: changed definition of BIT_AT
2967 to emit 'sbit at' instead of 'bit at'. This was a request.
2969 PIC16 port related preliminary changes:
2970 * gen.c: prefixed function popRegFromString with
2971 pic16_ and all references to it corrected
2972 * pcode.c: all pic16_pc_* hardware registers prefixed
2973 with underscore (_),
2974 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2975 * ralloc.c: newReg(): when register is REG_SFR then
2976 set address to rIdx,
2977 pic16_allocProcessorRegister(): marks register wasUsed=0
2978 pic16_writeUsedRegs(): added a call to assign processor
2979 registers via pic16_assignFixedRegisters
2981 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2983 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2984 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2985 variables in unused register banks. Also the SSEG is placed
2986 wherever there is enough space for it, and IDATA can be anywhere
2987 in internal RAM. For now compile using -Wl-Y[stack_size].
2988 The mem file is different for this option as well, since it
2989 makes no sense of talking about DSEG lenght.
2991 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2993 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2994 in certain cases, e.g. when ROM assignment, patch provided
2995 from Albert den Haan.

4002 copied from genNearPointerSet()
4003 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4004 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4020 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4021 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4022 type for bits was changed. It resulted in bit variables becoming
4023 global, which is not permitted in PIC 14 assembly output.

4040 A few small changes that speed up the peephole optimizer.
4044 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4046 Try to make the peephole optimizer smarter by maintaining
4047 an association between the assembly source code and the
4048 iCodes that originated them. Put this information to use
4049 with a new peephole rule condition "notVolatile" so that
4050 the rules can be aggressive yet still safe.
4055 * src/mcs51/peeph.def
4057 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4061 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4062 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4063 if the left or right operand symbols have the accuse flag set.
4065 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4067 Changed the type of the result of the ! (NOT) operator to char;
4068 previously it returned the same type as the source. This allows
4069 us to eliminate all the genFloatNot functions (all of its target
4070 implementations were very buggy) since !float can use the same

4082 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4083 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4084 during interrupts. Ensure WSAVE is located at a shared bank address.
4085 2. Fixed page selection in some places
4086 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4087 the registers name strings.
4088 4. Fixed "signed / unsigned compare" compiler warnings.
4089 5. The PIC port manages its own allocation of the general purpose
4090 registers, but makes no attempt to reuse them. As a result when
4091 compiling it soon runs out of general purpose registers. Some
4092 additional code was added to the files pcode.c and device.c to walk
4093 through the function call tree and rename the registers so that they
4103 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4110 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4112 Made bitfield a distinct type from bit so that bitfields
4113 convert as per ANSI C and bits retain their traditional
4114 boolean style behaviour. Implemented bitfield support in
4122 * src/ds390/gen.c: bit v bitfield split
4123 * src/z80/gen.c: New support for bitfields

4127 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4129 Rules 246.x, 247.x relate to bitfields, the others speed up
4130 access to xdata mapped I/O devices.
4132 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4134 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4136 Cleaned up genPackBits and genUnpackBits and added two helper

4146 Fixed bug #748310 (pointer to function type mishandled when the
4147 function name is omitted). Also fixed a SIGSEGV when a function
4148 attribute (reentrant, etc) is used on a non-function or on a
4149 function but misplaced before the parameter list.

4176 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4178 Made the constant following the "interrupt" keyword optional. If
4179 omitted, the function will not automatically be given an entry
4180 in the interrupt vector table (similar to #pragma NOIV, but
4181 less syntacticly kludgy). The interrupt number is also now
4182 range checked. Also fixed a bug in the high order bit example

4713 messages from optionsTable when a port is not configured, added
4714 support for the PIc16 port in the ports table, when executing
4715 the compiler with no port specified on command line, a default
4716 port is selected with the new macro DEFAULT_PORT which is
4717 defined in port.h, in setDefaultOptions() linkOptions is removed
4718 from initialization assignment, since now it is a set,
4719 parseCmdLine uses setParseWithComma for linkOptions, in
4720 linkEdit() linkOptions are accessed with new function indexSet()
4721 which returns the i'th item of a set variable. See SDCCset.c, in
4722 linkEdit() when calling buildCmdLine(), added linkOptions as
4723 last argument. Now users can pass arguments to gplink via the
4724 -Wl option, main() uses pic16glue() to glue up pic16 programs

4738 gpasm complaining and test the linkage with gplink, _linkCmd and
4739 _asmCmd changed to be more gplink and gpasm friendly
4740 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4741 produced an error when parsed, peep rule 12 is added to utilize
4742 movff, but it is commented out since the pCode does not support
4743 yet a command with 2 address arguments
4745 2003-05-18 <johan AT balder>
4747 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5782 * src/SDCCicode.c: fixed array add
5784 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5785 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5786 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5788 2003-01-04 <johan AT balder>
5790 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5792 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5793 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

5805 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5806 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5808 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5810 * in \sdcc\as\mcs51\ changed these files in order to create an
5811 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5812 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5813 following files to include the previous two files: aslink.dsp,
5814 Makefile.aslink, Makefile.bcc, and Makefile.in.
5816 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5817 .adb instead of .cdb
5819 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5821 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5822 value from option --iram-size.
5824 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5826 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5829 2002-09-18 <wiml AT hhhh.org>
5831 * SDCClrange.h: exposed setFromRange() and setToRange()
5832 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5833 packRegsForAccUse() (bug 542397)
5834 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5835 multiple times and emitting the fetch operations more than once
5836 added aopGetUsesAcc() function to allow binary operators to
5837 fetch their operands in the correct order; made genMinus() emit
5838 compact code for X = LITERAL - Y
5840 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5841 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5842 sprintf() in line 1267.
5844 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5845 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5848 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5849 Changes to aslink (All the changes are marked with 'JCF'):
5851 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5854 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5855 area BSEG. Also moves, if possible, the DATA area down into the internal
5856 ram so more space is available.
5858 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5861 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5862 not bytes. Function summary() which creates a memory usage summary
5863 file with extension .mem. Reports of overlaping stack and small stack
5864 size. If the space for the stack is less than 16 bytes aslink trows a
5867 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5868 the 8051. Option 'y' for memory summary output file.
5870 Changes to sdcc (All the changes are marked with 'JCF'):
5872 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5874 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5875 overlaying area for it (uses RegBankUsed[4]).
5877 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5878 bank zero as used by default. By default aslink locates the stack
5879 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5880 the creation of the .mem file. Delegates the allocation of data area
5881 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5882 the begining of the stack area to aslink.
5884 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5885 glue() in SDCCglue.c creates an area for it.
5887 2002-09-03 Borut Razem <borut.razem AT siol.net>
5888 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5889 sdcc/src/pic/glue.c:
5890 introduced atexit() handler for teporay files removal in case of
5891 errors, assertions, ...
5893 2002-08-29 Borut Razem <borut.razem AT siol.net>
5894 * sdcc/support/cpp2/auto-host_vc_in.h:
5895 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5896 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5897 Maybe there is a similar problem with BORLANDC? It should be checked!
5899 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5900 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5901 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5902 was not executed, and the compiler (cl) launched a warning:
5903 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5905 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5906 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5908 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5909 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5911 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5912 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5913 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5914 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5915 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5916 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5917 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5918 - added Release configuration in VS projects
5919 - review of compiler an linker options
5920 - VC .exe files are generated in bin_vc directory, not to interfere
5921 with binaries generated from other projects (cygwin, mingw, bcc ...)
5923 * sdcc/src/yacc.dsp: added
5925 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5926 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5927 and insert the version number definitions from .version
5929 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5931 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5932 added - genarate auto-host.h using auto-host_vc_in.h as template
5935 removed from CVS, generated automatically
5937 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5938 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5940 2002-08-11 Borut Razem <borut.razem AT siol.net>
5941 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5943 2002-08-10 Borut Razem <borut.razem AT siol.net>
5944 * src/SDCCmain.c (main):
5945 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5946 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5947 The consequence was that some temporary files were not removed.
5950 unification of code in functions tempfilename() and tempfile():
5951 function tempnam() is defined in Visual Studio 6.0 and .NET
5953 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5955 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5956 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5957 - removed compiler command line option /WX: Treats all warnings as errors
5958 - update a list of source files, included into the project
5960 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5961 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5962 changed project type to Generic Project so that can be correcly converted to VS.NET project
5964 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5966 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5968 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5970 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5971 added return 0 statements after assert() to make compiler happy
5973 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5974 added newline in the def file to keep MSC compiler satisfied
5976 * sdcc/src/z80/gen.c:
5977 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5978 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5979 - solved MSC error in function aopDump()
5981 * sdcc_vc.h: define PREFIX as "\\sdcc"
5983 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5984 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6023 2002-03-28 Johan Knol <johan AT balder>
6025 * src/SDCCval.c: fixed bug #532436
6027 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6029 Added "char *Processor" field to the port structure.
6032 Added -p option. Allows port dependent processor to be specified.
6035 Initialized the new field char *Processor field to NULL in all ports
6038 Compiler generated registers for interrupt context saving
6039 were not getting allocated.
6041 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6044 Fixed left shift. Will promote the left side of a left shift
6045 if a) left shifting more than size of operand or b) when assigned
6046 to something size > size of left side
6048 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6050 tons of changes. Register allocation has been
6051 rewritten. Added customization for the various PICs. Flow

6156 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6158 * sdcc/src/SDCCloop.c:
6159 Previous fix was not good. basic blocks that have "break" or "return" are
6160 not really partof a loop , but live ranges used in these blocks should
6161 be live thru the entire loop, so set partOfLoop but don't add them to
6164 2002-02-21 <johan AT FRIJA>
6166 * src/SDCCcse.c: fixed bug #514308
6168 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6171 Fixed BUG #519583. If a conditional block ended in a return/break
6172 statement inside a loop, it was not being considered part of the loop.
6174 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6176 2002-02-10 Karl Bongers <karl AT turbobit.com>
6179 Fixed up SDCDB debugger somewhat. Updated debugger/README
