2342 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
2344 * src/SDCCast.c: added an additional type flow in decorateType() of
2345 opposite direction, see feature request #860006; it's enabled at runtime
2346 by setting the environment variable SDCC_NEWTYPEFLOW

2431 loaded with the linker search paths (-L arguments) and the libraries
2432 to be linked with the current source (-l arguments). Changes
2433 currently will affect only the pic16 port.
2434 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2435 include path the port specific paths and port specific libraries,
2436 * gplink command now contains the $3 argument,
2437 * src/pic16/device.h,
2438 * src/pic16/device.c,: structure PIC_device is made public and
2439 renamed to PIC16_device, the same for variable Pics which is renamed

2454 Documenting changes from previous commits.
2455 * configure.in (version 1.56),
2456 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2457 when generating output files to configure the pic16 library,
2458 but now I've commented it out, since gputils aren't installed in the
2459 SF compile farm, so library won't compile
2461 * device/lib/Makefile.in (version 1.56): initially I've added in
2462 target 'all' the prerequestive 'model-pic16' so it compiled the
2463 pic16 library, but now I've commented it out for the same reasons
2465 * added targets 'model-pic16' and 'objects-pic16' to compile the
2467 * added target 'port-specific-objects-pic16' to handle the
2468 generated libraries and copy them into the build/ directory
2469 * added target 'clean-intermediate-pic16' to clean intermediate
2470 files into pic16 directory
2471 * in target 'installdirs' added line to create directory pic16 in

2784 the assembly output. Temporary hack, will be corrected later,
2785 because gplink yet does not support stack and SDCC does not
2786 yet support a type of crt0.o object to create the final binary.
2788 * Removed many lines that contain 8051 legacy code.
2789 * The code is finally placed under a 'code' directive.
2790 * Added port specific options.
2792 * _process_pragma: simplified since now we do not need *special*
2793 include file to define SFR registers. But a separate header
2794 will be needed. This will be developed later.
2795 * _pic16_parseOptions: added, parses port specific options:
2796 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2797 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2798 --preplace-udata-with=
2800 * _pic16_setDefaultOptions: modified to initialize section names,
2801 but hack is temporarly out of order since it needs improvement.
2802 * _pic16_genAssemblerPreamble: configuration words are emitted by
2803 their address instead of their name. This part is incomplete and
2804 supports only the 18Fxx2 devices. Other devices will emit an error
2805 during assembly since they do not contain the same set of config
2807 * _pic16_genIVT: is modified,
2809 * pcode.c: added definitions for some hardware registers that are needed
2811 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2812 All PCI entries are updated. Now LFSR is supported.
2813 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2814 * added pic16_newpCodeOpLit2 to support instructions with
2815 two literal arguments
2816 * pic16_pCode2str: corrected code that emits assembler instructions
2817 with two literal operands and those that have an access bit modifier
2818 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2819 this fixes a bug which caused some labels to be lost, when an
2820 assembler directive was added, i.e. banksel,
2821 * pic16_FixRegisterBanking: improved logic that causes the insertion
2823 * InlineFunction: functions that are called once, are not any more
2824 inlined. This can be a port option in the future,
2826 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2828 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2829 hold the corresponding uninitialized symbols,
2830 * pic16_allocProcessorRegister: registers have explicit marked the
2832 * pic16_allocInternalRegister: registers are explicit marked as
2834 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2835 processing list, so bit registers were lost,
2838 * ralloc.h: added field 'accessBank' and original symbol operand
2839 in register definition,
2840 * removed the field isMapped from register definition,
2842 ** Several functions have been removed from various sources:
2843 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2844 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2845 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2846 pic16_assignRelocatableRegisters
2848 ** others have been introduced:
2849 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2850 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2852 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2854 * support/scripts/inc2h.pl: changed definition of BIT_AT
2855 to emit 'sbit at' instead of 'bit at'. This was a request.
2857 PIC16 port related preliminary changes:
2858 * gen.c: prefixed function popRegFromString with
2859 pic16_ and all references to it corrected
2860 * pcode.c: all pic16_pc_* hardware registers prefixed
2861 with underscore (_),
2862 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2863 * ralloc.c: newReg(): when register is REG_SFR then
2864 set address to rIdx,
2865 pic16_allocProcessorRegister(): marks register wasUsed=0
2866 pic16_writeUsedRegs(): added a call to assign processor
2867 registers via pic16_assignFixedRegisters
2869 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2871 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2872 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2873 variables in unused register banks. Also the SSEG is placed
2874 wherever there is enough space for it, and IDATA can be anywhere
2875 in internal RAM. For now compile using -Wl-Y[stack_size].
2876 The mem file is different for this option as well, since it
2877 makes no sense of talking about DSEG lenght.
2879 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2881 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2882 in certain cases, e.g. when ROM assignment, patch provided
2883 from Albert den Haan.

3126 * src/SDCCast.c (decorateType): disabled a transformation I added in
3127 revision 1.188 (access to fields of a structure at an absolute address);
3128 it breaks with bitfields, extern declarations, and gcse analysis.
3129 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3130 could be assigned through a pointer, so don't complain.
3131 * src/SDCCast.c (astErrors),
3133 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

3235 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
3236 uninitialized variables) for the mcs51. Set environment variable
3237 SDCC_GENRAMCLEAR to test.
3238 xdata initialization slightly shorter
3240 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3771 support for standard C idiom of memory mapped variables; for
3772 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3773 to xdata int at 0x1234 tempvar = 1.

3887 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3888 fetching of the pointer
3889 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3890 copied from genNearPointerSet()
3891 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3892 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3893 If they pop r0/r1 they must be called in the opposite order than aopOp().

3908 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3909 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3910 type for bits was changed. It resulted in bit variables becoming
3911 global, which is not permitted in PIC 14 assembly output.
3913 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3915 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3928 A few small changes that speed up the peephole optimizer.
3932 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3934 Try to make the peephole optimizer smarter by maintaining
3935 an association between the assembly source code and the
3936 iCodes that originated them. Put this information to use
3937 with a new peephole rule condition "notVolatile" so that
3938 the rules can be aggressive yet still safe.
3943 * src/mcs51/peeph.def
3945 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3949 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3950 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3951 if the left or right operand symbols have the accuse flag set.
3953 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3955 Changed the type of the result of the ! (NOT) operator to char;
3956 previously it returned the same type as the source. This allows
3957 us to eliminate all the genFloatNot functions (all of its target
3958 implementations were very buggy) since !float can use the same
3961 * src/SDCCicode.c (ast2iCode): ! returns char

3970 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3971 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3972 during interrupts. Ensure WSAVE is located at a shared bank address.
3973 2. Fixed page selection in some places
3974 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3975 the registers name strings.
3976 4. Fixed "signed / unsigned compare" compiler warnings.
3977 5. The PIC port manages its own allocation of the general purpose
3978 registers, but makes no attempt to reuse them. As a result when
3979 compiling it soon runs out of general purpose registers. Some
3980 additional code was added to the files pcode.c and device.c to walk
3981 through the function call tree and rename the registers so that they
3991 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3998 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4000 Made bitfield a distinct type from bit so that bitfields
4001 convert as per ANSI C and bits retain their traditional
4002 boolean style behaviour. Implemented bitfield support in
4010 * src/ds390/gen.c: bit v bitfield split
4011 * src/z80/gen.c: New support for bitfields
4012 * support/regression/tests/bitfields.c: reenabled z80,
4015 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4017 Rules 246.x, 247.x relate to bitfields, the others speed up
4018 access to xdata mapped I/O devices.
4020 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4022 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4024 Cleaned up genPackBits and genUnpackBits and added two helper
4025 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4026 for literal assignments in genPackBits (thanks to Frieder for
4032 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4034 Fixed bug #748310 (pointer to function type mishandled when the
4035 function name is omitted). Also fixed a SIGSEGV when a function
4036 attribute (reentrant, etc) is used on a non-function or on a
4037 function but misplaced before the parameter list.
4039 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4041 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4042 * support/Util/SDCCerr.h,
4043 * support/Util/SDCCerr.c: Added func attr misuse error msg

4064 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4066 Made the constant following the "interrupt" keyword optional. If
4067 omitted, the function will not automatically be given an entry
4068 in the interrupt vector table (similar to #pragma NOIV, but
4069 less syntacticly kludgy). The interrupt number is also now
4070 range checked. Also fixed a bug in the high order bit example

4084 * src/SDCCicode.c (operandOperation): rewritten some ops
4085 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4086 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4088 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4089 be re-activated by defining REDUCE_LITERALS)
4090 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4091 unsigned, but are signed by default
4092 * src/SDCCval.c (constVal): rearranged
4093 * src/SDCCval.c (valMod): preliminary fix
4094 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4136 constants are unsigned; added recognition of "u" flag for unsigned
4137 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4138 * src/SDCCval.c (valDiv, valMod): fixed signdness
4139 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4140 signedness of modulo, left and right shift

4599 * src/SDCCmain.c: linkOptions is changed to set *,
4600 added if/endif conditional macros to remove options help
4601 messages from optionsTable when a port is not configured, added
4602 support for the PIc16 port in the ports table, when executing
4603 the compiler with no port specified on command line, a default
4604 port is selected with the new macro DEFAULT_PORT which is
4605 defined in port.h, in setDefaultOptions() linkOptions is removed
4606 from initialization assignment, since now it is a set,
4607 parseCmdLine uses setParseWithComma for linkOptions, in
4608 linkEdit() linkOptions are accessed with new function indexSet()
4609 which returns the i'th item of a set variable. See SDCCset.c, in
4610 linkEdit() when calling buildCmdLine(), added linkOptions as
4611 last argument. Now users can pass arguments to gplink via the
4612 -Wl option, main() uses pic16glue() to glue up pic16 programs

4624 * src/pic16/glue.c: commented out some error producing lines
4625 * src/pic16/main.c: __config directives are commented out to stop
4626 gpasm complaining and test the linkage with gplink, _linkCmd and
4627 _asmCmd changed to be more gplink and gpasm friendly
4628 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4629 produced an error when parsed, peep rule 12 is added to utilize
4630 movff, but it is commented out since the pCode does not support
4631 yet a command with 2 address arguments
4633 2003-05-18 <johan AT balder>
4635 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4662 2003-05-11 Borut Razem <borut.razem AT siol.net>
4664 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4665 the path of bin directory, so that PATH is the only env. variable, which has to be set
4666 in case of standard installation.

5701 following files to include the previous two files: aslink.dsp,
5702 Makefile.aslink, Makefile.bcc, and Makefile.in.
5704 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5705 .adb instead of .cdb
5707 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5709 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5710 value from option --iram-size.
5712 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5714 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5717 2002-09-18 <wiml AT hhhh.org>
5719 * SDCClrange.h: exposed setFromRange() and setToRange()
5720 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5721 packRegsForAccUse() (bug 542397)
5722 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5723 multiple times and emitting the fetch operations more than once
5724 added aopGetUsesAcc() function to allow binary operators to
5725 fetch their operands in the correct order; made genMinus() emit
5726 compact code for X = LITERAL - Y
5728 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5729 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5730 sprintf() in line 1267.
5732 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5733 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5736 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5737 Changes to aslink (All the changes are marked with 'JCF'):
5739 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5742 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5743 area BSEG. Also moves, if possible, the DATA area down into the internal
5744 ram so more space is available.
5746 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5749 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5750 not bytes. Function summary() which creates a memory usage summary
5751 file with extension .mem. Reports of overlaping stack and small stack
5752 size. If the space for the stack is less than 16 bytes aslink trows a
5755 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5756 the 8051. Option 'y' for memory summary output file.
5758 Changes to sdcc (All the changes are marked with 'JCF'):
5760 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5762 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5763 overlaying area for it (uses RegBankUsed[4]).
5765 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5766 bank zero as used by default. By default aslink locates the stack
5767 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5768 the creation of the .mem file. Delegates the allocation of data area
5769 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5770 the begining of the stack area to aslink.
5772 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5773 glue() in SDCCglue.c creates an area for it.
5775 2002-09-03 Borut Razem <borut.razem AT siol.net>
5776 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5777 sdcc/src/pic/glue.c:
5778 introduced atexit() handler for teporay files removal in case of
5779 errors, assertions, ...
5781 2002-08-29 Borut Razem <borut.razem AT siol.net>
5782 * sdcc/support/cpp2/auto-host_vc_in.h:
5783 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5784 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5785 Maybe there is a similar problem with BORLANDC? It should be checked!
5787 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5788 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5789 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5790 was not executed, and the compiler (cl) launched a warning:
5791 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5793 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5794 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5796 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5797 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5799 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5800 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5801 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5802 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5803 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5804 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5805 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5806 - added Release configuration in VS projects
5807 - review of compiler an linker options
5808 - VC .exe files are generated in bin_vc directory, not to interfere
5809 with binaries generated from other projects (cygwin, mingw, bcc ...)
5811 * sdcc/src/yacc.dsp: added
5813 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5814 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5815 and insert the version number definitions from .version
5817 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5819 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5820 added - genarate auto-host.h using auto-host_vc_in.h as template
5823 removed from CVS, generated automatically
5825 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5826 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5828 2002-08-11 Borut Razem <borut.razem AT siol.net>
5829 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5831 2002-08-10 Borut Razem <borut.razem AT siol.net>
5832 * src/SDCCmain.c (main):
5833 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5834 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5835 The consequence was that some temporary files were not removed.
5838 unification of code in functions tempfilename() and tempfile():
5839 function tempnam() is defined in Visual Studio 6.0 and .NET
5841 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5843 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5844 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5845 - removed compiler command line option /WX: Treats all warnings as errors
5846 - update a list of source files, included into the project
5848 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5849 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5850 changed project type to Generic Project so that can be correcly converted to VS.NET project
5852 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5854 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5856 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5858 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5859 added return 0 statements after assert() to make compiler happy
5861 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5862 added newline in the def file to keep MSC compiler satisfied
5864 * sdcc/src/z80/gen.c:
5865 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5866 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5867 - solved MSC error in function aopDump()
5869 * sdcc_vc.h: define PREFIX as "\\sdcc"
5871 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5872 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5875 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5876 - Rewrote the register banking algorithm.
5877 - Added pCode live-range analysis to registers (for now, only non-used and
5878 singly-used registers optimized away)
5880 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5882 * 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.

5911 2002-03-28 Johan Knol <johan AT balder>
5913 * src/SDCCval.c: fixed bug #532436
5915 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5917 Added "char *Processor" field to the port structure.
5920 Added -p option. Allows port dependent processor to be specified.
5923 Initialized the new field char *Processor field to NULL in all ports
5926 Compiler generated registers for interrupt context saving
5927 were not getting allocated.
5929 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5932 Fixed left shift. Will promote the left side of a left shift
5933 if a) left shifting more than size of operand or b) when assigned
5934 to something size > size of left side
5936 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5938 tons of changes. Register allocation has been
5939 rewritten. Added customization for the various PICs. Flow
5940 analysis is restructured. ...

6044 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6046 * sdcc/src/SDCCloop.c:
6047 Previous fix was not good. basic blocks that have "break" or "return" are
6048 not really partof a loop , but live ranges used in these blocks should
6049 be live thru the entire loop, so set partOfLoop but don't add them to
6052 2002-02-21 <johan AT FRIJA>
6054 * src/SDCCcse.c: fixed bug #514308
6056 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6059 Fixed BUG #519583. If a conditional block ended in a return/break
6060 statement inside a loop, it was not being considered part of the loop.
6062 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6064 2002-02-10 Karl Bongers <karl AT turbobit.com>
6067 Fixed up SDCDB debugger somewhat. Updated debugger/README
6068 with lots of comments and notes.
6070 * device/examples/test2.c:
6071 Fix bug, "red" variable not being initialized(compiler complained).
6073 * device/examples/Makefile, examples/test3.c:

6077 * sim/ucsim/cmd.src/cmdset.cc:
6078 Took out debug printfs in ucsim "next" command.
6081 Karl and Johan start ucsim XA support. Most dissassembly working,
6082 about 75% emulation done(plenty of work remaining).
6084 * sim/ucsim/z80.src:
6085 Add Z80 support to ucsim, add test-ucz80 regression test,
6086 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
