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

528 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
529 to call when a stack overflow occurs,
530 * (malloc.h): added CVS Id tag,
531 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
533 * added libc directory. The current version of LibC contains string
534 functions, ctype functions and macros and some functions of the
535 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
536 be extensively tested in the future. Standard disclaimer here.
537 Library is not automatically build yet. But one can build it by
538 invoking 'make' inside the libc directory.
539 * added ADC library under libio. Preliminary version yet.

549 * (pic16_storeForReturn): optimized return of 0,
550 * (genCmp): experimental code for new genCmp which uses PIC18's
551 special compare&skip instructions. Initial tests fail some times
552 with variables grater than 1 byte in size, so new code is disabled,
553 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
555 * (genCast): began a fix to optimize the casting of a bit to another
556 bit, now assigning a bitfield to another bitfield will fail, sorry,
557 * src/pic16/main.c: disabled the use of lr-support feature,
558 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

561 bits with offset (case PO_GPR_BIT),
562 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
564 * (isBankInstruction): modified to return 0 for no banking instruction,
565 and 1 for banking instruction,
566 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
567 caused stop processing pCodes after a inline assembly block,
568 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

570 registers when it shouldn't,
571 * src/pic16/ralloc.c (allocReg): add preliminary support for
572 supporting a limited set of temporary registers,
574 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
576 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
577 genDataPointerSet): ensure assignments always copy in MSB to LSB
579 (loadRegFromAop): recognize CLRH optimization,
580 (genFunction): optimize RECEIVE iCodes in reentrant functions
582 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
584 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3583 to be linked with the current source (-l arguments). Changes
3584 currently will affect only the pic16 port.
3585 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3586 include path the port specific paths and port specific libraries,
3587 * gplink command now contains the $3 argument,
3588 * src/pic16/device.h,
3589 * src/pic16/device.c,: structure PIC_device is made public and
3590 renamed to PIC16_device, the same for variable Pics which is renamed
3591 to Pics16. Updated all references to them.
3592 * src/pic16/glue.c (pic16glue): corrected bug with code
3593 initialization which bypassed the variable initializations block.
3595 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3596 COMPILE_FLAGS and added the --nostdinc option
3598 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3600 * device/include/mc68hc908jb8.h: Register defs for another member
3601 of the hc08 family. Contributed by Bjorn Bringert - thanks!
3603 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3605 Documenting changes from previous commits.
3606 * configure.in (version 1.56),
3607 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3608 when generating output files to configure the pic16 library,
3609 but now I've commented it out, since gputils aren't installed in the
3610 SF compile farm, so library won't compile
3612 * device/lib/Makefile.in (version 1.56): initially I've added in
3613 target 'all' the prerequestive 'model-pic16' so it compiled the
3614 pic16 library, but now I've commented it out for the same reasons
3616 * added targets 'model-pic16' and 'objects-pic16' to compile the
3618 * added target 'port-specific-objects-pic16' to handle the
3619 generated libraries and copy them into the build/ directory
3620 * added target 'clean-intermediate-pic16' to clean intermediate
3621 files into pic16 directory
3622 * in target 'installdirs' added line to create directory pic16 in
3623 the installation path
3625 * device/include/Makefile.in (version 1.11): in target 'install'
3626 added lines to copy all header files to installation path,
3627 * in target 'installdirs' added line create directory for pic16
3628 headers in the installation path

3643 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3644 option so that it actually works. Made it specific to the z80, since
3645 the gbz80 doesn't have these kinds of I/O ports.
3647 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3649 * device/include/z180.h,

3671 Mainly changes to support compilation of the device libraries
3672 * src/pic16/device.c: stack is allocated via symbol and not
3673 via literal number. The symbol is placed in the corresponding
3674 position of the data ram
3675 * (pic16_dump_section): relocatable and absolute uninitialized
3676 data are now emitted in sorted order to reduce section naming,
3677 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3678 weren't marked as being in the access bank,
3680 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3682 Added portion of GNU PIC Library under the directory
3683 device/include/pic16 and device/lib/pic16. These files
3684 contain the declarations of SFRs for the PIC18Fxx2 devices.
3685 The directory is initialized via configure from toplevel.
3687 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3689 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3690 the spilllocations to be compared correctly
3692 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3694 * src/SDCCast.c (decorateType): fixed bug introduced today
3696 2004-01-12 Borut Razem <borut.razem AT siol.net>

3714 * doc/sdccman.lyx: Moved and added some sections, small changes
3715 all over. Telling LaTeX to be less strict with word spacing
3716 to better keep the right margin. Changed some notes about
3717 maintainance of the ports in section 3.2.1 - is it OK like this?
3719 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3756 UPPER for immediate operands,
3757 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3759 * src/pic16/peeph.def: all peepholes with movff are commented out,
3760 because there is a problem in the pcode peep optimizer,
3761 * src/pic16/ralloc.c: the register allocator can now reuse local
3762 function symbols for another function. This saves register usage.
3763 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3765 Added file src/pic16/NOTES with information about program writing on
3766 the current port version.

3775 * src/SDCCmain.c : fixed #872250: -l command line defined library
3776 files are scanned before standard library files
3778 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3798 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3801 * src/z80/main.c: added missed needLinkerScript flags (more than
3802 one port structure defined in these file)
3803 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3819 needLinkerScript flag
3821 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3822 * src/pic/glue.c: added variable udata_section_name to
3823 override default uninitialized data segment definition for
3824 devices only with SHAREBANK memory (reported from Erik Epetrich)
3825 * (pic14emitOverlay): modified to emit a commented overlay segment
3826 directive when no overlay data exist
3827 * (picglue): modified to emit uninitialized data segment
3828 according to udata_section_name

3834 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3835 object file from '.rel' to '.o' in port->linker structure,

3838 2004-01-07 Borut Razem <borut.razem AT siol.net>
3840 * support/scripts/sdcc.nsi: update PATH
3841 * support/scripts/sdcc.ico: craeted
3843 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3846 * doc/Makefile: fix install
3848 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3850 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3852 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

3854 include information about variables allocated to the overlay
3857 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3859 * as/mcs51/lkmain.c: Help about -Y option

3871 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3873 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3874 (default behaviour).
3876 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3878 A python script to validate compiler diagnostic messages. It can be
3879 used to verify that sdcc complains about bad c source code and
3880 gives a good location of the error.
3881 * support/valdiag/Makefile,
3882 * support/valdiag/valdiag.py,
3883 * support/valdiag/tests/*
3885 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3898 * src/common.h: added ifndef/define/endif macros
3899 around the header file.
3900 Bug reported from Jesus Calvino-Fraga
3902 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3904 * sdcc.spec: updated
3905 * device/include/Makefile.in: don't install CVS directories
3906 * device/lib/Makefile.in: added removal of CVS directories after install
3907 * doc/Makefile: fixed install, added local_icons
3908 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3909 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3910 * src/ds390/gen.c (genRightShift): fixed bug #870788
3911 * src/SDCCast.c (decorateType): fixed bug #870781
3913 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3915 PIC16 port related changes:
3916 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3917 added variable stackPos,
3919 * gen.c: genCall, assignResultValue: added support for
3920 pushing/retrieving function parameters to/from stack,
3921 genFunction,genEndFunction: setup stack frame for the
3923 genAddrOf: will be changed according to bug 863624
3925 * added files genutils.c and genutils.h which contain gen*
3926 debugged and optimised functions extracted from gen.c
3928 * glue.c: added variable 'externs' which holds extern symbols,
3929 pic16emitRegularMap: is modified to properly handle relocatable
3930 symbols under the new scheme,
3931 pic16createInterruptVect: is modified
3932 pic16printPublics: is modified to emit 'global' assembler directives,
3933 added pic16_printExterns to print extern symbols,
3934 pic16glue: initializes stack/frame pointer in the beginning of
3935 the assembly output. Temporary hack, will be corrected later,
3936 because gplink yet does not support stack and SDCC does not
3937 yet support a type of crt0.o object to create the final binary.
3939 * Removed many lines that contain 8051 legacy code.
3940 * The code is finally placed under a 'code' directive.
3941 * Added port specific options.
3943 * _process_pragma: simplified since now we do not need *special*
3944 include file to define SFR registers. But a separate header
3945 will be needed. This will be developed later.
3946 * _pic16_parseOptions: added, parses port specific options:
3947 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3948 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3949 --preplace-udata-with=
3951 * _pic16_setDefaultOptions: modified to initialize section names,
3952 but hack is temporarly out of order since it needs improvement.
3953 * _pic16_genAssemblerPreamble: configuration words are emitted by
3954 their address instead of their name. This part is incomplete and
3955 supports only the 18Fxx2 devices. Other devices will emit an error
3956 during assembly since they do not contain the same set of config
3958 * _pic16_genIVT: is modified,
3960 * pcode.c: added definitions for some hardware registers that are needed
3962 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3963 All PCI entries are updated. Now LFSR is supported.
3964 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3965 * added pic16_newpCodeOpLit2 to support instructions with
3966 two literal arguments
3967 * pic16_pCode2str: corrected code that emits assembler instructions
3968 with two literal operands and those that have an access bit modifier
3969 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3970 this fixes a bug which caused some labels to be lost, when an
3971 assembler directive was added, i.e. banksel,
3972 * pic16_FixRegisterBanking: improved logic that causes the insertion
3974 * InlineFunction: functions that are called once, are not any more
3975 inlined. This can be a port option in the future,
3977 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3979 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3980 hold the corresponding uninitialized symbols,
3981 * pic16_allocProcessorRegister: registers have explicit marked the
3983 * pic16_allocInternalRegister: registers are explicit marked as
3985 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3986 processing list, so bit registers were lost,
3989 * ralloc.h: added field 'accessBank' and original symbol operand
3990 in register definition,
3991 * removed the field isMapped from register definition,
3993 ** Several functions have been removed from various sources:
3994 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3995 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3996 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3997 pic16_assignRelocatableRegisters
3999 ** others have been introduced:
4000 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4001 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4003 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4005 * support/scripts/inc2h.pl: changed definition of BIT_AT
4006 to emit 'sbit at' instead of 'bit at'. This was a request.
4008 PIC16 port related preliminary changes:
4009 * gen.c: prefixed function popRegFromString with
4010 pic16_ and all references to it corrected
4011 * pcode.c: all pic16_pc_* hardware registers prefixed
4012 with underscore (_),
4013 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4014 * ralloc.c: newReg(): when register is REG_SFR then
4015 set address to rIdx,
4016 pic16_allocProcessorRegister(): marks register wasUsed=0
4017 pic16_writeUsedRegs(): added a call to assign processor
4018 registers via pic16_assignFixedRegisters
4020 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4022 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4023 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4024 variables in unused register banks. Also the SSEG is placed
4025 wherever there is enough space for it, and IDATA can be anywhere
4026 in internal RAM. For now compile using -Wl-Y[stack_size].
4027 The mem file is different for this option as well, since it
4028 makes no sense of talking about DSEG lenght.
4030 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4032 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4033 in certain cases, e.g. when ROM assignment, patch provided
4034 from Albert den Haan.
4036 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5064 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5066 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5079 A few small changes that speed up the peephole optimizer.
5083 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5085 Try to make the peephole optimizer smarter by maintaining
5086 an association between the assembly source code and the
5087 iCodes that originated them. Put this information to use
5088 with a new peephole rule condition "notVolatile" so that
5089 the rules can be aggressive yet still safe.
5094 * src/mcs51/peeph.def
5096 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5100 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5101 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5102 if the left or right operand symbols have the accuse flag set.
5104 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5106 Changed the type of the result of the ! (NOT) operator to char;
5107 previously it returned the same type as the source. This allows
5108 us to eliminate all the genFloatNot functions (all of its target
5109 implementations were very buggy) since !float can use the same
5112 * src/SDCCicode.c (ast2iCode): ! returns char

5121 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5122 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5123 during interrupts. Ensure WSAVE is located at a shared bank address.
5124 2. Fixed page selection in some places
5125 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5126 the registers name strings.
5127 4. Fixed "signed / unsigned compare" compiler warnings.
5128 5. The PIC port manages its own allocation of the general purpose
5129 registers, but makes no attempt to reuse them. As a result when
5130 compiling it soon runs out of general purpose registers. Some
5131 additional code was added to the files pcode.c and device.c to walk
5132 through the function call tree and rename the registers so that they
5142 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5143 genPlus() & genMinus() when the result is the same as left or right
5145 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5149 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5151 Made bitfield a distinct type from bit so that bitfields
5152 convert as per ANSI C and bits retain their traditional
5153 boolean style behaviour. Implemented bitfield support in
5161 * src/ds390/gen.c: bit v bitfield split
5162 * src/z80/gen.c: New support for bitfields
5163 * support/regression/tests/bitfields.c: reenabled z80,
5166 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5168 Rules 246.x, 247.x relate to bitfields, the others speed up
5169 access to xdata mapped I/O devices.
5171 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5173 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5175 Cleaned up genPackBits and genUnpackBits and added two helper
5176 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5177 for literal assignments in genPackBits (thanks to Frieder for
5183 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5185 Fixed bug #748310 (pointer to function type mishandled when the
5186 function name is omitted). Also fixed a SIGSEGV when a function
5187 attribute (reentrant, etc) is used on a non-function or on a
5188 function but misplaced before the parameter list.
5190 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5192 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5215 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5217 Made the constant following the "interrupt" keyword optional. If
5218 omitted, the function will not automatically be given an entry
5219 in the interrupt vector table (similar to #pragma NOIV, but
5220 less syntacticly kludgy). The interrupt number is also now
5221 range checked. Also fixed a bug in the high order bit example

5242 unsigned, but are signed by default
5243 * src/SDCCval.c (constVal): rearranged
5244 * src/SDCCval.c (valMod): preliminary fix
5245 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5664 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5666 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
5667 is in parts still quite out of date, I did changes as far as I felt makes sense
5668 for a non-native english speaker.
5669 Please feel free to add to the manual or to correct my changes.
5670 * doc/Makefile: undid touching the date of intermediate tex files.
5672 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5689 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
5690 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5691 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5692 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5695 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5697 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5698 the regression tests I'm not brave enough to enable 245.b, 245.c
5699 * doc/sdccman.lyx: added latex preamble for hyperref package.
5700 Using pdflatex this will give you a hyperlinked pdf file with
5701 bookmarks. (prepend '%' before /usepackage if this breaks something)
5703 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5717 Applied patch from bug 737905 (renamed yylineo to mylineno):
5724 * src/pic16/pcode.c: Cleaned warnings
5725 * src/pic16/pcodeflow.c: Cleaned warnings
5726 * src/pic16/pcoderegs.c: Cleaned warnings

5739 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5741 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5742 it can be defined with CFLAGS when running configure
5743 * src/SDCCmain.c: fixed compiling + linking with object files
5745 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5747 * configure.in: configure for pic16 port,
5748 added --disable-pic16-port
5749 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5750 * src/SDCCmain.c: linkOptions is changed to set *,
5751 added if/endif conditional macros to remove options help
5752 messages from optionsTable when a port is not configured, added
5753 support for the PIc16 port in the ports table, when executing
5754 the compiler with no port specified on command line, a default
5755 port is selected with the new macro DEFAULT_PORT which is
5756 defined in port.h, in setDefaultOptions() linkOptions is removed
5757 from initialization assignment, since now it is a set,
5758 parseCmdLine uses setParseWithComma for linkOptions, in
5759 linkEdit() linkOptions are accessed with new function indexSet()
5760 which returns the i'th item of a set variable. See SDCCset.c, in
5761 linkEdit() when calling buildCmdLine(), added linkOptions as
5762 last argument. Now users can pass arguments to gplink via the
5763 -Wl option, main() uses pic16glue() to glue up pic16 programs
5764 * src/SDCCpeeph.c: various changes to support pic16

5773 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5775 * src/pic16/glue.c: commented out some error producing lines
5776 * src/pic16/main.c: __config directives are commented out to stop
5777 gpasm complaining and test the linkage with gplink, _linkCmd and
5778 _asmCmd changed to be more gplink and gpasm friendly
5779 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5780 produced an error when parsed, peep rule 12 is added to utilize
5781 movff, but it is commented out since the pCode does not support
5782 yet a command with 2 address arguments
5784 2003-05-18 <johan AT balder>
5786 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5787 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5806 on entry now. Add tbreak. Other enhancements and fixes for use
5809 2003-05-12 Borut Razem <borut.razem AT siol.net>
5811 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5813 2003-05-11 Borut Razem <borut.razem AT siol.net>
5815 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5816 the path of bin directory, so that PATH is the only env. variable, which has to be set
5817 in case of standard installation.
5818 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6847 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6849 * in \sdcc\as\mcs51\ changed these files in order to create an
6850 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6851 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6852 following files to include the previous two files: aslink.dsp,
6853 Makefile.aslink, Makefile.bcc, and Makefile.in.
6855 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6856 .adb instead of .cdb
6858 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6860 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6861 value from option --iram-size.
6863 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6865 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6868 2002-09-18 <wiml AT hhhh.org>
6870 * SDCClrange.h: exposed setFromRange() and setToRange()
6871 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6872 packRegsForAccUse() (bug 542397)
6873 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6874 multiple times and emitting the fetch operations more than once
6875 added aopGetUsesAcc() function to allow binary operators to
6876 fetch their operands in the correct order; made genMinus() emit
6877 compact code for X = LITERAL - Y
6879 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6880 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6881 sprintf() in line 1267.
6883 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6884 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6887 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6888 Changes to aslink (All the changes are marked with 'JCF'):
6890 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6893 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6894 area BSEG. Also moves, if possible, the DATA area down into the internal
6895 ram so more space is available.
6897 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6900 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6901 not bytes. Function summary() which creates a memory usage summary
6902 file with extension .mem. Reports of overlaping stack and small stack
6903 size. If the space for the stack is less than 16 bytes aslink trows a
6906 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6907 the 8051. Option 'y' for memory summary output file.
6909 Changes to sdcc (All the changes are marked with 'JCF'):
6911 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6913 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6914 overlaying area for it (uses RegBankUsed[4]).
6916 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6917 bank zero as used by default. By default aslink locates the stack
6918 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6919 the creation of the .mem file. Delegates the allocation of data area
6920 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6921 the begining of the stack area to aslink.
6923 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6924 glue() in SDCCglue.c creates an area for it.
6926 2002-09-03 Borut Razem <borut.razem AT siol.net>
6927 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6928 sdcc/src/pic/glue.c:
6929 introduced atexit() handler for teporay files removal in case of
6930 errors, assertions, ...
6932 2002-08-29 Borut Razem <borut.razem AT siol.net>
6933 * sdcc/support/cpp2/auto-host_vc_in.h:
6934 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6935 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6936 Maybe there is a similar problem with BORLANDC? It should be checked!
6938 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6939 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6940 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6941 was not executed, and the compiler (cl) launched a warning:
6942 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6944 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6962 * sdcc/src/yacc.dsp: added
6964 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6965 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6966 and insert the version number definitions from .version
6968 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6970 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6974 removed from CVS, generated automatically
6976 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6977 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6979 2002-08-11 Borut Razem <borut.razem AT siol.net>
6980 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6982 2002-08-10 Borut Razem <borut.razem AT siol.net>
6983 * src/SDCCmain.c (main):
6984 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6985 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6986 The consequence was that some temporary files were not removed.
6989 unification of code in functions tempfilename() and tempfile():
6990 function tempnam() is defined in Visual Studio 6.0 and .NET
6992 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6994 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6995 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6996 - removed compiler command line option /WX: Treats all warnings as errors
6997 - update a list of source files, included into the project
6999 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7000 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7001 changed project type to Generic Project so that can be correcly converted to VS.NET project
7003 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7005 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7007 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7009 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7010 added return 0 statements after assert() to make compiler happy
7012 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7013 added newline in the def file to keep MSC compiler satisfied
7015 * sdcc/src/z80/gen.c:
7016 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7017 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7018 - solved MSC error in function aopDump()
7020 * sdcc_vc.h: define PREFIX as "\\sdcc"
7022 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7078 were not getting allocated.
7080 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7083 Fixed left shift. Will promote the left side of a left shift
7084 if a) left shifting more than size of operand or b) when assigned
7085 to something size > size of left side
7087 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7197 * sdcc/src/SDCCloop.c:
7198 Previous fix was not good. basic blocks that have "break" or "return" are
7199 not really partof a loop , but live ranges used in these blocks should
7200 be live thru the entire loop, so set partOfLoop but don't add them to
7203 2002-02-21 <johan AT FRIJA>
