499 Adding support for replacing ljmps with sjmps in jumptables
500 generated for switch statements. For now you need to set the
501 environment variable SDCC_SJMP_JUMPTABLE to enable this.
502 Now 4 algorithms for mcs51 jumptable generation are used:
503 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
504 addresses loaded pc-relative for up to 112 cases and stack-pushing
505 target addresses loaded with offset from dptr for up to 256 cases.

533 to call when a stack overflow occurs,
534 * (malloc.h): added CVS Id tag,
535 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
537 * added libc directory. The current version of LibC contains string
538 functions, ctype functions and macros and some functions of the
539 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
540 be extensively tested in the future. Standard disclaimer here.
541 Library is not automatically build yet. But one can build it by
542 invoking 'make' inside the libc directory.
543 * added ADC library under libio. Preliminary version yet.

554 * (genCmp): experimental code for new genCmp which uses PIC18's
555 special compare&skip instructions. Initial tests fail some times
556 with variables grater than 1 byte in size, so new code is disabled,
557 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
559 * (genCast): began a fix to optimize the casting of a bit to another
560 bit, now assigning a bitfield to another bitfield will fail, sorry,

568 * (isBankInstruction): modified to return 0 for no banking instruction,
569 and 1 for banking instruction,

571 caused stop processing pCodes after a inline assembly block,
572 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3585 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3586 loaded with the linker search paths (-L arguments) and the libraries
3587 to be linked with the current source (-l arguments). Changes
3588 currently will affect only the pic16 port.
3589 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3590 include path the port specific paths and port specific libraries,
3591 * gplink command now contains the $3 argument,
3592 * src/pic16/device.h,
3593 * src/pic16/device.c,: structure PIC_device is made public and
3594 renamed to PIC16_device, the same for variable Pics which is renamed
3595 to Pics16. Updated all references to them.
3596 * src/pic16/glue.c (pic16glue): corrected bug with code
3597 initialization which bypassed the variable initializations block.
3599 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3600 COMPILE_FLAGS and added the --nostdinc option
3602 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3604 * device/include/mc68hc908jb8.h: Register defs for another member
3605 of the hc08 family. Contributed by Bjorn Bringert - thanks!
3607 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3609 Documenting changes from previous commits.
3610 * configure.in (version 1.56),
3611 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3612 when generating output files to configure the pic16 library,
3613 but now I've commented it out, since gputils aren't installed in the
3614 SF compile farm, so library won't compile
3616 * device/lib/Makefile.in (version 1.56): initially I've added in
3617 target 'all' the prerequestive 'model-pic16' so it compiled the
3618 pic16 library, but now I've commented it out for the same reasons
3620 * added targets 'model-pic16' and 'objects-pic16' to compile the
3622 * added target 'port-specific-objects-pic16' to handle the
3623 generated libraries and copy them into the build/ directory
3624 * added target 'clean-intermediate-pic16' to clean intermediate
3625 files into pic16 directory
3626 * in target 'installdirs' added line to create directory pic16 in
3627 the installation path
3629 * device/include/Makefile.in (version 1.11): in target 'install'
3630 added lines to copy all header files to installation path,
3631 * in target 'installdirs' added line create directory for pic16
3632 headers in the installation path
3634 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3647 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3648 option so that it actually works. Made it specific to the z80, since
3649 the gbz80 doesn't have these kinds of I/O ports.
3651 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3653 * device/include/z180.h,

3666 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3668 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3669 changed interrupt vector table generation to only emit declared vectors.
3670 * device/include/Makefile.in: added missing backslash
3671 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

3675 Mainly changes to support compilation of the device libraries
3676 * src/pic16/device.c: stack is allocated via symbol and not
3677 via literal number. The symbol is placed in the corresponding
3678 position of the data ram
3679 * (pic16_dump_section): relocatable and absolute uninitialized
3680 data are now emitted in sorted order to reduce section naming,
3681 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3682 weren't marked as being in the access bank,
3684 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3686 Added portion of GNU PIC Library under the directory
3687 device/include/pic16 and device/lib/pic16. These files
3688 contain the declarations of SFRs for the PIC18Fxx2 devices.
3689 The directory is initialized via configure from toplevel.
3691 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3693 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3694 the spilllocations to be compared correctly
3696 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3698 * src/SDCCast.c (decorateType): fixed bug introduced today
3700 2004-01-12 Borut Razem <borut.razem AT siol.net>
3702 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3718 * doc/sdccman.lyx: Moved and added some sections, small changes
3719 all over. Telling LaTeX to be less strict with word spacing
3720 to better keep the right margin. Changed some notes about
3721 maintainance of the ports in section 3.2.1 - is it OK like this?
3723 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3725 SDCC source changes:
3726 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3760 UPPER for immediate operands,
3761 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3763 * src/pic16/peeph.def: all peepholes with movff are commented out,
3764 because there is a problem in the pcode peep optimizer,
3765 * src/pic16/ralloc.c: the register allocator can now reuse local
3766 function symbols for another function. This saves register usage.
3767 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3769 Added file src/pic16/NOTES with information about program writing on
3770 the current port version.

3779 * src/SDCCmain.c : fixed #872250: -l command line defined library
3780 files are scanned before standard library files
3782 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3799 gen51Code): more efficient parameter receive for --model-large
3802 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3805 * src/z80/main.c: added missed needLinkerScript flags (more than
3806 one port structure defined in these file)
3807 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3813 * src/port.h: added flag needLinkerScript in port->linker
3814 structure to inform whether to create a .lnk file or not,
3822 * src/z80/main.c: changed appropriately to configure
3823 needLinkerScript flag
3825 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3826 * src/pic/glue.c: added variable udata_section_name to
3827 override default uninitialized data segment definition for
3828 devices only with SHAREBANK memory (reported from Erik Epetrich)
3829 * (pic14emitOverlay): modified to emit a commented overlay segment
3830 directive when no overlay data exist
3831 * (picglue): modified to emit uninitialized data segment
3832 according to udata_section_name
3833 * src/pic/main.c (_pic14_parseOptions): added command line

3837 arguments via -W option
3838 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3839 object file from '.rel' to '.o' in port->linker structure,
3840 changed size of fptr from 2 to 3 in port structure
3842 2004-01-07 Borut Razem <borut.razem AT siol.net>
3844 * support/scripts/sdcc.nsi: update PATH
3845 * support/scripts/sdcc.ico: craeted
3847 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3850 * doc/Makefile: fix install
3852 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3854 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3856 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3857 how the function variable allocation summary is displayed; also
3858 include information about variables allocated to the overlay
3861 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3863 * as/mcs51/lkmain.c: Help about -Y option

3875 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3877 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3878 (default behaviour).
3880 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3882 A python script to validate compiler diagnostic messages. It can be
3883 used to verify that sdcc complains about bad c source code and
3884 gives a good location of the error.
3885 * support/valdiag/Makefile,
3886 * support/valdiag/valdiag.py,
3887 * support/valdiag/tests/*
3889 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3891 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3900 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3902 * src/common.h: added ifndef/define/endif macros
3903 around the header file.
3904 Bug reported from Jesus Calvino-Fraga
3906 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3908 * sdcc.spec: updated
3909 * device/include/Makefile.in: don't install CVS directories
3910 * device/lib/Makefile.in: added removal of CVS directories after install
3911 * doc/Makefile: fixed install, added local_icons
3912 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3913 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3914 * src/ds390/gen.c (genRightShift): fixed bug #870788
3915 * src/SDCCast.c (decorateType): fixed bug #870781
3917 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3919 PIC16 port related changes:
3920 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3921 added variable stackPos,
3923 * gen.c: genCall, assignResultValue: added support for
3924 pushing/retrieving function parameters to/from stack,
3925 genFunction,genEndFunction: setup stack frame for the
3927 genAddrOf: will be changed according to bug 863624
3929 * added files genutils.c and genutils.h which contain gen*
3930 debugged and optimised functions extracted from gen.c
3932 * glue.c: added variable 'externs' which holds extern symbols,
3933 pic16emitRegularMap: is modified to properly handle relocatable
3934 symbols under the new scheme,
3935 pic16createInterruptVect: is modified
3936 pic16printPublics: is modified to emit 'global' assembler directives,
3937 added pic16_printExterns to print extern symbols,
3938 pic16glue: initializes stack/frame pointer in the beginning of
3939 the assembly output. Temporary hack, will be corrected later,
3940 because gplink yet does not support stack and SDCC does not
3941 yet support a type of crt0.o object to create the final binary.
3943 * Removed many lines that contain 8051 legacy code.
3944 * The code is finally placed under a 'code' directive.
3945 * Added port specific options.
3947 * _process_pragma: simplified since now we do not need *special*
3948 include file to define SFR registers. But a separate header
3949 will be needed. This will be developed later.
3950 * _pic16_parseOptions: added, parses port specific options:
3951 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3952 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3953 --preplace-udata-with=
3955 * _pic16_setDefaultOptions: modified to initialize section names,
3956 but hack is temporarly out of order since it needs improvement.
3957 * _pic16_genAssemblerPreamble: configuration words are emitted by
3958 their address instead of their name. This part is incomplete and
3959 supports only the 18Fxx2 devices. Other devices will emit an error
3960 during assembly since they do not contain the same set of config
3962 * _pic16_genIVT: is modified,
3964 * pcode.c: added definitions for some hardware registers that are needed
3966 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3967 All PCI entries are updated. Now LFSR is supported.
3968 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3969 * added pic16_newpCodeOpLit2 to support instructions with
3970 two literal arguments
3971 * pic16_pCode2str: corrected code that emits assembler instructions
3972 with two literal operands and those that have an access bit modifier
3973 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3974 this fixes a bug which caused some labels to be lost, when an
3975 assembler directive was added, i.e. banksel,
3976 * pic16_FixRegisterBanking: improved logic that causes the insertion
3978 * InlineFunction: functions that are called once, are not any more
3979 inlined. This can be a port option in the future,
3981 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3983 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3984 hold the corresponding uninitialized symbols,
3985 * pic16_allocProcessorRegister: registers have explicit marked the
3987 * pic16_allocInternalRegister: registers are explicit marked as
3989 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3990 processing list, so bit registers were lost,
3993 * ralloc.h: added field 'accessBank' and original symbol operand
3994 in register definition,
3995 * removed the field isMapped from register definition,
3997 ** Several functions have been removed from various sources:
3998 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3999 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4000 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4001 pic16_assignRelocatableRegisters
4003 ** others have been introduced:
4004 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4005 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4007 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4009 * support/scripts/inc2h.pl: changed definition of BIT_AT
4010 to emit 'sbit at' instead of 'bit at'. This was a request.
4012 PIC16 port related preliminary changes:
4013 * gen.c: prefixed function popRegFromString with
4014 pic16_ and all references to it corrected
4015 * pcode.c: all pic16_pc_* hardware registers prefixed
4016 with underscore (_),
4017 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4018 * ralloc.c: newReg(): when register is REG_SFR then
4019 set address to rIdx,
4020 pic16_allocProcessorRegister(): marks register wasUsed=0
4021 pic16_writeUsedRegs(): added a call to assign processor
4022 registers via pic16_assignFixedRegisters
4024 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4026 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4027 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4028 variables in unused register banks. Also the SSEG is placed
4029 wherever there is enough space for it, and IDATA can be anywhere
4030 in internal RAM. For now compile using -Wl-Y[stack_size].
4031 The mem file is different for this option as well, since it
4032 makes no sense of talking about DSEG lenght.
4034 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4036 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4037 in certain cases, e.g. when ROM assignment, patch provided
4038 from Albert den Haan.
4040 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5065 type for bits was changed. It resulted in bit variables becoming
5066 global, which is not permitted in PIC 14 assembly output.
5068 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5070 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5072 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5074 Z80 and MCS51 linkers complaint if a public symbol is defined
5075 in more than one library module:

5083 A few small changes that speed up the peephole optimizer.
5087 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5089 Try to make the peephole optimizer smarter by maintaining
5090 an association between the assembly source code and the
5091 iCodes that originated them. Put this information to use
5092 with a new peephole rule condition "notVolatile" so that
5093 the rules can be aggressive yet still safe.
5098 * src/mcs51/peeph.def
5100 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5104 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5105 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5106 if the left or right operand symbols have the accuse flag set.
5108 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5110 Changed the type of the result of the ! (NOT) operator to char;
5111 previously it returned the same type as the source. This allows
5112 us to eliminate all the genFloatNot functions (all of its target
5113 implementations were very buggy) since !float can use the same
5116 * src/SDCCicode.c (ast2iCode): ! returns char

5125 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5126 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5127 during interrupts. Ensure WSAVE is located at a shared bank address.
5128 2. Fixed page selection in some places
5129 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5130 the registers name strings.
5131 4. Fixed "signed / unsigned compare" compiler warnings.
5132 5. The PIC port manages its own allocation of the general purpose
5133 registers, but makes no attempt to reuse them. As a result when
5134 compiling it soon runs out of general purpose registers. Some
5135 additional code was added to the files pcode.c and device.c to walk
5136 through the function call tree and rename the registers so that they
5146 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5147 genPlus() & genMinus() when the result is the same as left or right

5153 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5155 Made bitfield a distinct type from bit so that bitfields
5156 convert as per ANSI C and bits retain their traditional
5157 boolean style behaviour. Implemented bitfield support in
5165 * src/ds390/gen.c: bit v bitfield split
5166 * src/z80/gen.c: New support for bitfields
5167 * support/regression/tests/bitfields.c: reenabled z80,
5170 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5172 Rules 246.x, 247.x relate to bitfields, the others speed up
5173 access to xdata mapped I/O devices.
5175 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5177 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5179 Cleaned up genPackBits and genUnpackBits and added two helper
5180 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5181 for literal assignments in genPackBits (thanks to Frieder for
5187 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5189 Fixed bug #748310 (pointer to function type mishandled when the
5190 function name is omitted). Also fixed a SIGSEGV when a function
5191 attribute (reentrant, etc) is used on a non-function or on a
5192 function but misplaced before the parameter list.
5194 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5196 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5197 * support/Util/SDCCerr.h,

5219 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5221 Made the constant following the "interrupt" keyword optional. If
5222 omitted, the function will not automatically be given an entry
5223 in the interrupt vector table (similar to #pragma NOIV, but
5224 less syntacticly kludgy). The interrupt number is also now
5225 range checked. Also fixed a bug in the high order bit example

5241 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5243 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5244 be re-activated by defining REDUCE_LITERALS)
5245 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5246 unsigned, but are signed by default
5247 * src/SDCCval.c (constVal): rearranged
5248 * src/SDCCval.c (valMod): preliminary fix
5249 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5292 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5293 * src/SDCCval.c (valDiv, valMod): fixed signdness
5294 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5295 signedness of modulo, left and right shift

5668 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5670 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
5671 is in parts still quite out of date, I did changes as far as I felt makes sense
5672 for a non-native english speaker.
5673 Please feel free to add to the manual or to correct my changes.

5694 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5695 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5696 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5699 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5701 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5702 the regression tests I'm not brave enough to enable 245.b, 245.c
5703 * doc/sdccman.lyx: added latex preamble for hyperref package.
5704 Using pdflatex this will give you a hyperlinked pdf file with
5705 bookmarks. (prepend '%' before /usepackage if this breaks something)
5707 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5721 Applied patch from bug 737905 (renamed yylineo to mylineno):
5728 * src/pic16/pcode.c: Cleaned warnings
5729 * src/pic16/pcodeflow.c: Cleaned warnings
5730 * src/pic16/pcoderegs.c: Cleaned warnings

5743 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5745 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5746 it can be defined with CFLAGS when running configure
5747 * src/SDCCmain.c: fixed compiling + linking with object files
5749 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5751 * configure.in: configure for pic16 port,
5752 added --disable-pic16-port
5753 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5754 * src/SDCCmain.c: linkOptions is changed to set *,
5755 added if/endif conditional macros to remove options help
5756 messages from optionsTable when a port is not configured, added
5757 support for the PIc16 port in the ports table, when executing
5758 the compiler with no port specified on command line, a default
5759 port is selected with the new macro DEFAULT_PORT which is
5760 defined in port.h, in setDefaultOptions() linkOptions is removed
5761 from initialization assignment, since now it is a set,
5762 parseCmdLine uses setParseWithComma for linkOptions, in
5763 linkEdit() linkOptions are accessed with new function indexSet()
5764 which returns the i'th item of a set variable. See SDCCset.c, in
5765 linkEdit() when calling buildCmdLine(), added linkOptions as
5766 last argument. Now users can pass arguments to gplink via the
5767 -Wl option, main() uses pic16glue() to glue up pic16 programs
5768 * src/SDCCpeeph.c: various changes to support pic16

5779 * src/pic16/glue.c: commented out some error producing lines
5780 * src/pic16/main.c: __config directives are commented out to stop
5781 gpasm complaining and test the linkage with gplink, _linkCmd and
5782 _asmCmd changed to be more gplink and gpasm friendly
5783 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5784 produced an error when parsed, peep rule 12 is added to utilize
5785 movff, but it is commented out since the pCode does not support
5786 yet a command with 2 address arguments
5788 2003-05-18 <johan AT balder>
5790 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5791 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5792 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

5810 on entry now. Add tbreak. Other enhancements and fixes for use
5813 2003-05-12 Borut Razem <borut.razem AT siol.net>
5815 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5817 2003-05-11 Borut Razem <borut.razem AT siol.net>
5819 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5820 the path of bin directory, so that PATH is the only env. variable, which has to be set
5821 in case of standard installation.
5822 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6851 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6853 * in \sdcc\as\mcs51\ changed these files in order to create an
6854 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6855 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6856 following files to include the previous two files: aslink.dsp,
6857 Makefile.aslink, Makefile.bcc, and Makefile.in.
6859 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6860 .adb instead of .cdb
6862 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6864 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6865 value from option --iram-size.
6867 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6869 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6872 2002-09-18 <wiml AT hhhh.org>
6874 * SDCClrange.h: exposed setFromRange() and setToRange()
6875 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6876 packRegsForAccUse() (bug 542397)
6877 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6878 multiple times and emitting the fetch operations more than once
6879 added aopGetUsesAcc() function to allow binary operators to
6880 fetch their operands in the correct order; made genMinus() emit
6881 compact code for X = LITERAL - Y
6883 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6884 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6885 sprintf() in line 1267.
6887 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6888 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6891 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6892 Changes to aslink (All the changes are marked with 'JCF'):
6894 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6897 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6898 area BSEG. Also moves, if possible, the DATA area down into the internal
6899 ram so more space is available.
6901 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6904 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6905 not bytes. Function summary() which creates a memory usage summary
6906 file with extension .mem. Reports of overlaping stack and small stack
6907 size. If the space for the stack is less than 16 bytes aslink trows a
6910 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6911 the 8051. Option 'y' for memory summary output file.
6913 Changes to sdcc (All the changes are marked with 'JCF'):
6915 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6917 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6918 overlaying area for it (uses RegBankUsed[4]).
6920 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6921 bank zero as used by default. By default aslink locates the stack
6922 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6923 the creation of the .mem file. Delegates the allocation of data area
6924 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6925 the begining of the stack area to aslink.
6927 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6928 glue() in SDCCglue.c creates an area for it.
6930 2002-09-03 Borut Razem <borut.razem AT siol.net>
6931 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6932 sdcc/src/pic/glue.c:
6933 introduced atexit() handler for teporay files removal in case of
6934 errors, assertions, ...
6936 2002-08-29 Borut Razem <borut.razem AT siol.net>
6937 * sdcc/support/cpp2/auto-host_vc_in.h:
6938 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6939 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6940 Maybe there is a similar problem with BORLANDC? It should be checked!
6942 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6943 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6944 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6945 was not executed, and the compiler (cl) launched a warning:
6946 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6948 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6961 - added Release configuration in VS projects
6962 - review of compiler an linker options
6963 - VC .exe files are generated in bin_vc directory, not to interfere
6964 with binaries generated from other projects (cygwin, mingw, bcc ...)
6966 * sdcc/src/yacc.dsp: added
6968 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6969 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6970 and insert the version number definitions from .version
6972 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6974 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6975 added - genarate auto-host.h using auto-host_vc_in.h as template

6981 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6983 2002-08-11 Borut Razem <borut.razem AT siol.net>
6984 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6986 2002-08-10 Borut Razem <borut.razem AT siol.net>
6987 * src/SDCCmain.c (main):
6988 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6989 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6990 The consequence was that some temporary files were not removed.
6993 unification of code in functions tempfilename() and tempfile():
6994 function tempnam() is defined in Visual Studio 6.0 and .NET
6996 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6998 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6999 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7000 - removed compiler command line option /WX: Treats all warnings as errors
7001 - update a list of source files, included into the project
7003 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7004 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7005 changed project type to Generic Project so that can be correcly converted to VS.NET project
7007 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7009 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7011 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7013 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7014 added return 0 statements after assert() to make compiler happy
7016 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7017 added newline in the def file to keep MSC compiler satisfied
7019 * sdcc/src/z80/gen.c:
7020 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7021 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7022 - solved MSC error in function aopDump()
7024 * sdcc_vc.h: define PREFIX as "\\sdcc"
7026 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7082 were not getting allocated.
7084 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7087 Fixed left shift. Will promote the left side of a left shift
7088 if a) left shifting more than size of operand or b) when assigned
7089 to something size > size of left side

7201 * sdcc/src/SDCCloop.c:
7202 Previous fix was not good. basic blocks that have "break" or "return" are
7203 not really partof a loop , but live ranges used in these blocks should
7204 be live thru the entire loop, so set partOfLoop but don't add them to
