2435 loaded with the linker search paths (-L arguments) and the libraries
2436 to be linked with the current source (-l arguments). Changes
2437 currently will affect only the pic16 port.
2438 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2439 include path the port specific paths and port specific libraries,
2440 * gplink command now contains the $3 argument,
2441 * src/pic16/device.h,
2442 * src/pic16/device.c,: structure PIC_device is made public and
2443 renamed to PIC16_device, the same for variable Pics which is renamed

2458 Documenting changes from previous commits.
2459 * configure.in (version 1.56),
2460 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2461 when generating output files to configure the pic16 library,
2462 but now I've commented it out, since gputils aren't installed in the
2463 SF compile farm, so library won't compile
2465 * device/lib/Makefile.in (version 1.56): initially I've added in
2466 target 'all' the prerequestive 'model-pic16' so it compiled the
2467 pic16 library, but now I've commented it out for the same reasons
2469 * added targets 'model-pic16' and 'objects-pic16' to compile the
2471 * added target 'port-specific-objects-pic16' to handle the
2472 generated libraries and copy them into the build/ directory
2473 * added target 'clean-intermediate-pic16' to clean intermediate
2474 files into pic16 directory
2475 * in target 'installdirs' added line to create directory pic16 in

2786 added pic16_printExterns to print extern symbols,
2787 pic16glue: initializes stack/frame pointer in the beginning of
2788 the assembly output. Temporary hack, will be corrected later,
2789 because gplink yet does not support stack and SDCC does not
2790 yet support a type of crt0.o object to create the final binary.
2792 * Removed many lines that contain 8051 legacy code.
2793 * The code is finally placed under a 'code' directive.
2794 * Added port specific options.
2796 * _process_pragma: simplified since now we do not need *special*
2797 include file to define SFR registers. But a separate header
2798 will be needed. This will be developed later.
2799 * _pic16_parseOptions: added, parses port specific options:
2800 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2801 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2802 --preplace-udata-with=
2804 * _pic16_setDefaultOptions: modified to initialize section names,
2805 but hack is temporarly out of order since it needs improvement.
2806 * _pic16_genAssemblerPreamble: configuration words are emitted by
2807 their address instead of their name. This part is incomplete and
2808 supports only the 18Fxx2 devices. Other devices will emit an error
2809 during assembly since they do not contain the same set of config
2811 * _pic16_genIVT: is modified,
2813 * pcode.c: added definitions for some hardware registers that are needed
2815 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2816 All PCI entries are updated. Now LFSR is supported.
2817 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2818 * added pic16_newpCodeOpLit2 to support instructions with
2819 two literal arguments
2820 * pic16_pCode2str: corrected code that emits assembler instructions
2821 with two literal operands and those that have an access bit modifier
2822 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2823 this fixes a bug which caused some labels to be lost, when an
2824 assembler directive was added, i.e. banksel,
2825 * pic16_FixRegisterBanking: improved logic that causes the insertion
2827 * InlineFunction: functions that are called once, are not any more
2828 inlined. This can be a port option in the future,
2830 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2832 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2833 hold the corresponding uninitialized symbols,
2834 * pic16_allocProcessorRegister: registers have explicit marked the
2836 * pic16_allocInternalRegister: registers are explicit marked as
2838 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2839 processing list, so bit registers were lost,
2842 * ralloc.h: added field 'accessBank' and original symbol operand
2843 in register definition,
2844 * removed the field isMapped from register definition,
2846 ** Several functions have been removed from various sources:
2847 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2848 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2849 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2850 pic16_assignRelocatableRegisters
2852 ** others have been introduced:
2853 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2854 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2856 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2858 * support/scripts/inc2h.pl: changed definition of BIT_AT
2859 to emit 'sbit at' instead of 'bit at'. This was a request.
2861 PIC16 port related preliminary changes:
2862 * gen.c: prefixed function popRegFromString with
2863 pic16_ and all references to it corrected
2864 * pcode.c: all pic16_pc_* hardware registers prefixed
2865 with underscore (_),
2866 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2867 * ralloc.c: newReg(): when register is REG_SFR then
2868 set address to rIdx,
2869 pic16_allocProcessorRegister(): marks register wasUsed=0
2870 pic16_writeUsedRegs(): added a call to assign processor
2871 registers via pic16_assignFixedRegisters
2873 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2875 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2876 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2877 variables in unused register banks. Also the SSEG is placed
2878 wherever there is enough space for it, and IDATA can be anywhere
2879 in internal RAM. For now compile using -Wl-Y[stack_size].
2880 The mem file is different for this option as well, since it
2881 makes no sense of talking about DSEG lenght.
2883 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2885 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2886 in certain cases, e.g. when ROM assignment, patch provided
2887 from Albert den Haan.

3130 * src/SDCCast.c (decorateType): disabled a transformation I added in
3131 revision 1.188 (access to fields of a structure at an absolute address);
3132 it breaks with bitfields, extern declarations, and gcse analysis.
3133 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3134 could be assigned through a pointer, so don't complain.
3135 * src/SDCCast.c (astErrors),
3137 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

3239 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
3240 uninitialized variables) for the mcs51. Set environment variable
3241 SDCC_GENRAMCLEAR to test.
3242 xdata initialization slightly shorter
3244 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3891 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3892 fetching of the pointer
3893 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3894 copied from genNearPointerSet()
3895 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3896 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3912 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3913 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3914 type for bits was changed. It resulted in bit variables becoming
3915 global, which is not permitted in PIC 14 assembly output.
3917 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3932 A few small changes that speed up the peephole optimizer.
3936 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3938 Try to make the peephole optimizer smarter by maintaining
3939 an association between the assembly source code and the
3940 iCodes that originated them. Put this information to use
3941 with a new peephole rule condition "notVolatile" so that
3942 the rules can be aggressive yet still safe.
3947 * src/mcs51/peeph.def
3949 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3953 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3954 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3955 if the left or right operand symbols have the accuse flag set.
3957 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3959 Changed the type of the result of the ! (NOT) operator to char;
3960 previously it returned the same type as the source. This allows
3961 us to eliminate all the genFloatNot functions (all of its target
3962 implementations were very buggy) since !float can use the same

3975 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3976 during interrupts. Ensure WSAVE is located at a shared bank address.
3977 2. Fixed page selection in some places
3978 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3979 the registers name strings.
3980 4. Fixed "signed / unsigned compare" compiler warnings.
3981 5. The PIC port manages its own allocation of the general purpose
3982 registers, but makes no attempt to reuse them. As a result when
3983 compiling it soon runs out of general purpose registers. Some
3984 additional code was added to the files pcode.c and device.c to walk
3985 through the function call tree and rename the registers so that they
3995 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4002 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4004 Made bitfield a distinct type from bit so that bitfields
4005 convert as per ANSI C and bits retain their traditional
4006 boolean style behaviour. Implemented bitfield support in
4014 * src/ds390/gen.c: bit v bitfield split
4015 * src/z80/gen.c: New support for bitfields
4016 * support/regression/tests/bitfields.c: reenabled z80,
4019 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4021 Rules 246.x, 247.x relate to bitfields, the others speed up
4022 access to xdata mapped I/O devices.
4024 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4026 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4028 Cleaned up genPackBits and genUnpackBits and added two helper
4029 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4030 for literal assignments in genPackBits (thanks to Frieder for
4036 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4038 Fixed bug #748310 (pointer to function type mishandled when the
4039 function name is omitted). Also fixed a SIGSEGV when a function
4040 attribute (reentrant, etc) is used on a non-function or on a
4041 function but misplaced before the parameter list.
4043 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4045 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4068 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4070 Made the constant following the "interrupt" keyword optional. If
4071 omitted, the function will not automatically be given an entry
4072 in the interrupt vector table (similar to #pragma NOIV, but
4073 less syntacticly kludgy). The interrupt number is also now
4074 range checked. Also fixed a bug in the high order bit example

4088 * src/SDCCicode.c (operandOperation): rewritten some ops
4089 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4090 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4092 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4093 be re-activated by defining REDUCE_LITERALS)
4094 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4095 unsigned, but are signed by default
4096 * src/SDCCval.c (constVal): rearranged
4097 * src/SDCCval.c (valMod): preliminary fix
4098 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4603 * src/SDCCmain.c: linkOptions is changed to set *,
4604 added if/endif conditional macros to remove options help
4605 messages from optionsTable when a port is not configured, added
4606 support for the PIc16 port in the ports table, when executing
4607 the compiler with no port specified on command line, a default
4608 port is selected with the new macro DEFAULT_PORT which is
4609 defined in port.h, in setDefaultOptions() linkOptions is removed
4610 from initialization assignment, since now it is a set,
4611 parseCmdLine uses setParseWithComma for linkOptions, in
4612 linkEdit() linkOptions are accessed with new function indexSet()
4613 which returns the i'th item of a set variable. See SDCCset.c, in
4614 linkEdit() when calling buildCmdLine(), added linkOptions as
4615 last argument. Now users can pass arguments to gplink via the
4616 -Wl option, main() uses pic16glue() to glue up pic16 programs

4628 * src/pic16/glue.c: commented out some error producing lines
4629 * src/pic16/main.c: __config directives are commented out to stop
4630 gpasm complaining and test the linkage with gplink, _linkCmd and
4631 _asmCmd changed to be more gplink and gpasm friendly
4632 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4633 produced an error when parsed, peep rule 12 is added to utilize
4634 movff, but it is commented out since the pCode does not support
4635 yet a command with 2 address arguments
4637 2003-05-18 <johan AT balder>
4639 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4666 2003-05-11 Borut Razem <borut.razem AT siol.net>
4668 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4669 the path of bin directory, so that PATH is the only env. variable, which has to be set
4670 in case of standard installation.

5703 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5704 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5705 following files to include the previous two files: aslink.dsp,
5706 Makefile.aslink, Makefile.bcc, and Makefile.in.
5708 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5709 .adb instead of .cdb
5711 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5713 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5714 value from option --iram-size.
5716 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5718 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5721 2002-09-18 <wiml AT hhhh.org>
5723 * SDCClrange.h: exposed setFromRange() and setToRange()
5724 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5725 packRegsForAccUse() (bug 542397)
5726 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5727 multiple times and emitting the fetch operations more than once
5728 added aopGetUsesAcc() function to allow binary operators to
5729 fetch their operands in the correct order; made genMinus() emit
5730 compact code for X = LITERAL - Y
5732 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5733 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5734 sprintf() in line 1267.
5736 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5737 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5740 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5741 Changes to aslink (All the changes are marked with 'JCF'):
5743 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5746 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5747 area BSEG. Also moves, if possible, the DATA area down into the internal
5748 ram so more space is available.
5750 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5753 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5754 not bytes. Function summary() which creates a memory usage summary
5755 file with extension .mem. Reports of overlaping stack and small stack
5756 size. If the space for the stack is less than 16 bytes aslink trows a
5759 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5760 the 8051. Option 'y' for memory summary output file.
5762 Changes to sdcc (All the changes are marked with 'JCF'):
5764 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5766 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5767 overlaying area for it (uses RegBankUsed[4]).
5769 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5770 bank zero as used by default. By default aslink locates the stack
5771 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5772 the creation of the .mem file. Delegates the allocation of data area
5773 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5774 the begining of the stack area to aslink.
5776 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5777 glue() in SDCCglue.c creates an area for it.
5779 2002-09-03 Borut Razem <borut.razem AT siol.net>
5780 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5781 sdcc/src/pic/glue.c:
5782 introduced atexit() handler for teporay files removal in case of
5783 errors, assertions, ...
5785 2002-08-29 Borut Razem <borut.razem AT siol.net>
5786 * sdcc/support/cpp2/auto-host_vc_in.h:
5787 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5788 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5789 Maybe there is a similar problem with BORLANDC? It should be checked!
5791 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5792 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5793 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5794 was not executed, and the compiler (cl) launched a warning:
5795 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5797 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5798 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5800 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5801 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5803 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5804 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5805 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5806 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5807 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5808 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5809 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5810 - added Release configuration in VS projects
5811 - review of compiler an linker options
5812 - VC .exe files are generated in bin_vc directory, not to interfere
5813 with binaries generated from other projects (cygwin, mingw, bcc ...)
5815 * sdcc/src/yacc.dsp: added
5817 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5818 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5819 and insert the version number definitions from .version
5821 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5823 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5824 added - genarate auto-host.h using auto-host_vc_in.h as template
5827 removed from CVS, generated automatically
5829 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5830 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5832 2002-08-11 Borut Razem <borut.razem AT siol.net>
5833 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5835 2002-08-10 Borut Razem <borut.razem AT siol.net>
5836 * src/SDCCmain.c (main):
5837 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5838 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5839 The consequence was that some temporary files were not removed.
5842 unification of code in functions tempfilename() and tempfile():
5843 function tempnam() is defined in Visual Studio 6.0 and .NET
5845 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5847 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5848 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5849 - removed compiler command line option /WX: Treats all warnings as errors
5850 - update a list of source files, included into the project
5852 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5853 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5854 changed project type to Generic Project so that can be correcly converted to VS.NET project
5856 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5858 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5860 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5862 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5863 added return 0 statements after assert() to make compiler happy
5865 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5866 added newline in the def file to keep MSC compiler satisfied
5868 * sdcc/src/z80/gen.c:
5869 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5870 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5871 - solved MSC error in function aopDump()
5873 * sdcc_vc.h: define PREFIX as "\\sdcc"
5875 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5876 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5879 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5880 - Rewrote the register banking algorithm.
5881 - Added pCode live-range analysis to registers (for now, only non-used and
5882 singly-used registers optimized away)
5884 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

5915 2002-03-28 Johan Knol <johan AT balder>
5917 * src/SDCCval.c: fixed bug #532436
5919 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5921 Added "char *Processor" field to the port structure.
5924 Added -p option. Allows port dependent processor to be specified.
5927 Initialized the new field char *Processor field to NULL in all ports
5930 Compiler generated registers for interrupt context saving
5931 were not getting allocated.
5933 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5936 Fixed left shift. Will promote the left side of a left shift
5937 if a) left shifting more than size of operand or b) when assigned
5938 to something size > size of left side
5940 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5942 tons of changes. Register allocation has been
5943 rewritten. Added customization for the various PICs. Flow

6048 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6050 * sdcc/src/SDCCloop.c:
6051 Previous fix was not good. basic blocks that have "break" or "return" are
6052 not really partof a loop , but live ranges used in these blocks should
6053 be live thru the entire loop, so set partOfLoop but don't add them to
6056 2002-02-21 <johan AT FRIJA>
6058 * src/SDCCcse.c: fixed bug #514308
6060 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6064 statement inside a loop, it was not being considered part of the loop.
6066 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6068 2002-02-10 Karl Bongers <karl AT turbobit.com>
6071 Fixed up SDCDB debugger somewhat. Updated debugger/README
6072 with lots of comments and notes.
6074 * device/examples/test2.c:
6075 Fix bug, "red" variable not being initialized(compiler complained).
