452 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
454 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
456 (setFromConditionArgs): friendly operand parser for peephole rules,
457 (operandBaseName, operandsNotRelated): new peephole condition
458 "operandsNotRelated" -- similar to "operandsNotSame", but takes
459 architecture specific register naming into account, handles n-way
460 comparisons, and supports quoted literals
461 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
463 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

471 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
473 Adding support for replacing ljmps with sjmps in jumptables
474 generated for switch statements. For now you need to set the
475 environment variable SDCC_SJMP_JUMPTABLE to enable this.
476 Now 4 algorithms for mcs51 jumptable generation are used:
477 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
478 addresses loaded pc-relative for up to 112 cases and stack-pushing
479 target addresses loaded with offset from dptr for up to 256 cases.
481 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
482 * src/mcs51/main.c: adapted constants for switch table generation
483 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

505 Large cummulative patch for pic16 port.
506 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
507 to call when a stack overflow occurs,
508 * (malloc.h): added CVS Id tag,
509 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
511 * added libc directory. The current version of LibC contains string
512 functions, ctype functions and macros and some functions of the
513 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
514 be extensively tested in the future. Standard disclaimer here.
515 Library is not automatically build yet. But one can build it by
516 invoking 'make' inside the libc directory.
517 * added ADC library under libio. Preliminary version yet.
519 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

527 * (pic16_storeForReturn): optimized return of 0,
528 * (genCmp): experimental code for new genCmp which uses PIC18's
529 special compare&skip instructions. Initial tests fail some times
530 with variables grater than 1 byte in size, so new code is disabled,
531 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
533 * (genCast): began a fix to optimize the casting of a bit to another
534 bit, now assigning a bitfield to another bitfield will fail, sorry,
535 * src/pic16/main.c: disabled the use of lr-support feature,
536 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
537 * added some function prototypes, added function _debugf prototype,

539 bits with offset (case PO_GPR_BIT),
540 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
542 * (isBankInstruction): modified to return 0 for no banking instruction,
543 and 1 for banking instruction,
544 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
545 caused stop processing pCodes after a inline assembly block,
546 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
547 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
548 registers when it shouldn't,
549 * src/pic16/ralloc.c (allocReg): add preliminary support for
550 supporting a limited set of temporary registers,
552 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
554 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
555 genDataPointerSet): ensure assignments always copy in MSB to LSB
557 (loadRegFromAop): recognize CLRH optimization,
558 (genFunction): optimize RECEIVE iCodes in reentrant functions
560 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
562 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
563 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
565 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3560 loaded with the linker search paths (-L arguments) and the libraries
3561 to be linked with the current source (-l arguments). Changes
3562 currently will affect only the pic16 port.
3563 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3564 include path the port specific paths and port specific libraries,
3565 * gplink command now contains the $3 argument,
3566 * src/pic16/device.h,
3567 * src/pic16/device.c,: structure PIC_device is made public and

3583 Documenting changes from previous commits.
3584 * configure.in (version 1.56),
3585 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3586 when generating output files to configure the pic16 library,
3587 but now I've commented it out, since gputils aren't installed in the
3588 SF compile farm, so library won't compile
3590 * device/lib/Makefile.in (version 1.56): initially I've added in
3591 target 'all' the prerequestive 'model-pic16' so it compiled the
3592 pic16 library, but now I've commented it out for the same reasons
3594 * added targets 'model-pic16' and 'objects-pic16' to compile the
3596 * added target 'port-specific-objects-pic16' to handle the
3597 generated libraries and copy them into the build/ directory
3598 * added target 'clean-intermediate-pic16' to clean intermediate
3599 files into pic16 directory
3600 * in target 'installdirs' added line to create directory pic16 in
3601 the installation path
3603 * device/include/Makefile.in (version 1.11): in target 'install'
3604 added lines to copy all header files to installation path,
3605 * in target 'installdirs' added line create directory for pic16
3606 headers in the installation path
3608 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3621 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3622 option so that it actually works. Made it specific to the z80, since
3623 the gbz80 doesn't have these kinds of I/O ports.
3625 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3627 * device/include/z180.h,

3633 * device/lib/_strcmp.c,
3634 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
3635 * src/z80/main.c (_process_pragma): add support for pragmas bank and
3636 portmode; added deprecation warning for bank= and protmode= forms.
3637 Also, guard against buffer overflow.
3638 * src/z80/gen.c (aopGet): generate better code for sfr banked read
3640 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3642 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3643 changed interrupt vector table generation to only emit declared vectors.
3644 * device/include/Makefile.in: added missing backslash
3645 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
3647 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3649 Mainly changes to support compilation of the device libraries
3650 * src/pic16/device.c: stack is allocated via symbol and not
3651 via literal number. The symbol is placed in the corresponding
3652 position of the data ram
3653 * (pic16_dump_section): relocatable and absolute uninitialized
3654 data are now emitted in sorted order to reduce section naming,
3655 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3656 weren't marked as being in the access bank,
3658 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3660 Added portion of GNU PIC Library under the directory
3661 device/include/pic16 and device/lib/pic16. These files
3662 contain the declarations of SFRs for the PIC18Fxx2 devices.
3663 The directory is initialized via configure from toplevel.
3665 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3667 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3668 the spilllocations to be compared correctly
3670 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3672 * src/SDCCast.c (decorateType): fixed bug introduced today
3674 2004-01-12 Borut Razem <borut.razem AT siol.net>

3692 * doc/sdccman.lyx: Moved and added some sections, small changes
3693 all over. Telling LaTeX to be less strict with word spacing
3694 to better keep the right margin. Changed some notes about
3695 maintainance of the ports in section 3.2.1 - is it OK like this?
3697 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3734 UPPER for immediate operands,
3735 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3737 * src/pic16/peeph.def: all peepholes with movff are commented out,
3738 because there is a problem in the pcode peep optimizer,
3739 * src/pic16/ralloc.c: the register allocator can now reuse local

3741 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3743 Added file src/pic16/NOTES with information about program writing on
3744 the current port version.

3803 * (pic14emitOverlay): modified to emit a commented overlay segment
3804 directive when no overlay data exist
3805 * (picglue): modified to emit uninitialized data segment
3806 according to udata_section_name

3816 2004-01-07 Borut Razem <borut.razem AT siol.net>
3818 * support/scripts/sdcc.nsi: update PATH
3819 * support/scripts/sdcc.ico: craeted

3832 include information about variables allocated to the overlay
3835 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3837 * as/mcs51/lkmain.c: Help about -Y option

3849 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3851 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3852 (default behaviour).
3854 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3856 A python script to validate compiler diagnostic messages. It can be
3857 used to verify that sdcc complains about bad c source code and
3858 gives a good location of the error.
3859 * support/valdiag/Makefile,
3860 * support/valdiag/valdiag.py,
3861 * support/valdiag/tests/*

3876 * src/common.h: added ifndef/define/endif macros
3877 around the header file.
3878 Bug reported from Jesus Calvino-Fraga
3880 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3882 * sdcc.spec: updated
3883 * device/include/Makefile.in: don't install CVS directories
3884 * device/lib/Makefile.in: added removal of CVS directories after install
3885 * doc/Makefile: fixed install, added local_icons
3886 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3887 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3888 * src/ds390/gen.c (genRightShift): fixed bug #870788
3889 * src/SDCCast.c (decorateType): fixed bug #870781
3891 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3893 PIC16 port related changes:
3894 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3895 added variable stackPos,
3897 * gen.c: genCall, assignResultValue: added support for
3898 pushing/retrieving function parameters to/from stack,
3899 genFunction,genEndFunction: setup stack frame for the
3901 genAddrOf: will be changed according to bug 863624
3903 * added files genutils.c and genutils.h which contain gen*
3904 debugged and optimised functions extracted from gen.c
3906 * glue.c: added variable 'externs' which holds extern symbols,
3907 pic16emitRegularMap: is modified to properly handle relocatable
3908 symbols under the new scheme,
3909 pic16createInterruptVect: is modified
3910 pic16printPublics: is modified to emit 'global' assembler directives,
3911 added pic16_printExterns to print extern symbols,
3912 pic16glue: initializes stack/frame pointer in the beginning of
3913 the assembly output. Temporary hack, will be corrected later,
3914 because gplink yet does not support stack and SDCC does not
3915 yet support a type of crt0.o object to create the final binary.
3917 * Removed many lines that contain 8051 legacy code.
3918 * The code is finally placed under a 'code' directive.
3919 * Added port specific options.
3921 * _process_pragma: simplified since now we do not need *special*
3922 include file to define SFR registers. But a separate header
3923 will be needed. This will be developed later.
3924 * _pic16_parseOptions: added, parses port specific options:
3925 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3926 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3927 --preplace-udata-with=
3929 * _pic16_setDefaultOptions: modified to initialize section names,
3930 but hack is temporarly out of order since it needs improvement.
3931 * _pic16_genAssemblerPreamble: configuration words are emitted by
3932 their address instead of their name. This part is incomplete and
3933 supports only the 18Fxx2 devices. Other devices will emit an error
3934 during assembly since they do not contain the same set of config
3936 * _pic16_genIVT: is modified,
3938 * pcode.c: added definitions for some hardware registers that are needed
3940 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3941 All PCI entries are updated. Now LFSR is supported.
3942 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3943 * added pic16_newpCodeOpLit2 to support instructions with
3944 two literal arguments
3945 * pic16_pCode2str: corrected code that emits assembler instructions
3946 with two literal operands and those that have an access bit modifier
3947 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3948 this fixes a bug which caused some labels to be lost, when an
3949 assembler directive was added, i.e. banksel,
3950 * pic16_FixRegisterBanking: improved logic that causes the insertion
3952 * InlineFunction: functions that are called once, are not any more
3953 inlined. This can be a port option in the future,
3955 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3957 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3958 hold the corresponding uninitialized symbols,
3959 * pic16_allocProcessorRegister: registers have explicit marked the
3961 * pic16_allocInternalRegister: registers are explicit marked as
3963 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3964 processing list, so bit registers were lost,
3967 * ralloc.h: added field 'accessBank' and original symbol operand
3968 in register definition,
3969 * removed the field isMapped from register definition,
3971 ** Several functions have been removed from various sources:
3972 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3973 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3974 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3975 pic16_assignRelocatableRegisters
3977 ** others have been introduced:
3978 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3979 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3981 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3983 * support/scripts/inc2h.pl: changed definition of BIT_AT
3984 to emit 'sbit at' instead of 'bit at'. This was a request.
3986 PIC16 port related preliminary changes:
3987 * gen.c: prefixed function popRegFromString with
3988 pic16_ and all references to it corrected
3989 * pcode.c: all pic16_pc_* hardware registers prefixed
3990 with underscore (_),
3991 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3992 * ralloc.c: newReg(): when register is REG_SFR then
3993 set address to rIdx,
3994 pic16_allocProcessorRegister(): marks register wasUsed=0
3995 pic16_writeUsedRegs(): added a call to assign processor
3996 registers via pic16_assignFixedRegisters
3998 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4000 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4001 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4002 variables in unused register banks. Also the SSEG is placed
4003 wherever there is enough space for it, and IDATA can be anywhere
4004 in internal RAM. For now compile using -Wl-Y[stack_size].
4005 The mem file is different for this option as well, since it
4006 makes no sense of talking about DSEG lenght.
4008 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4010 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4011 in certain cases, e.g. when ROM assignment, patch provided
4012 from Albert den Haan.
4014 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4561 Fixed a number of problems revealed by bug #827883.
4562 * src/SDCCloop.c (loopInvariants): Spill location of the
4563 result operand should be recomputed if extracted from
4564 a loop. Also, don't extract assignments of an iTemp
4566 * src/SDCCast.c (isConformingBody): loop reversal should
4567 not occur if the control variable is involved with a
4568 relational operator.

5065 iCodes that originated them. Put this information to use
5066 with a new peephole rule condition "notVolatile" so that
5067 the rules can be aggressive yet still safe.
5072 * src/mcs51/peeph.def
5074 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5078 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5079 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5080 if the left or right operand symbols have the accuse flag set.
5082 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5084 Changed the type of the result of the ! (NOT) operator to char;
5085 previously it returned the same type as the source. This allows
5086 us to eliminate all the genFloatNot functions (all of its target
5087 implementations were very buggy) since !float can use the same
5090 * src/SDCCicode.c (ast2iCode): ! returns char

5099 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5100 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5101 during interrupts. Ensure WSAVE is located at a shared bank address.
5102 2. Fixed page selection in some places
5103 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5104 the registers name strings.
5105 4. Fixed "signed / unsigned compare" compiler warnings.
5106 5. The PIC port manages its own allocation of the general purpose
5107 registers, but makes no attempt to reuse them. As a result when
5108 compiling it soon runs out of general purpose registers. Some
5109 additional code was added to the files pcode.c and device.c to walk
5110 through the function call tree and rename the registers so that they
5120 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5127 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5129 Made bitfield a distinct type from bit so that bitfields
5130 convert as per ANSI C and bits retain their traditional
5131 boolean style behaviour. Implemented bitfield support in
5139 * src/ds390/gen.c: bit v bitfield split
5140 * src/z80/gen.c: New support for bitfields
5141 * support/regression/tests/bitfields.c: reenabled z80,
5144 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5146 Rules 246.x, 247.x relate to bitfields, the others speed up
5147 access to xdata mapped I/O devices.
5149 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5151 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5153 Cleaned up genPackBits and genUnpackBits and added two helper
5154 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5155 for literal assignments in genPackBits (thanks to Frieder for
5161 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5163 Fixed bug #748310 (pointer to function type mishandled when the
5164 function name is omitted). Also fixed a SIGSEGV when a function
5165 attribute (reentrant, etc) is used on a non-function or on a
5166 function but misplaced before the parameter list.

5193 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5195 Made the constant following the "interrupt" keyword optional. If
5196 omitted, the function will not automatically be given an entry
5197 in the interrupt vector table (similar to #pragma NOIV, but
5198 less syntacticly kludgy). The interrupt number is also now
5199 range checked. Also fixed a bug in the high order bit example

5659 * device/lib/gbz80/mul.s
5660 * device/lib/gbz80/stubs.s
5661 * device/lib/z80/mul.s
5662 * device/lib/z80/stubs.s
5663 * src/SDCCsymt.c (initCSupport)
5665 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5667 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
5668 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5669 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5670 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5673 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5675 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5676 the regression tests I'm not brave enough to enable 245.b, 245.c
5677 * doc/sdccman.lyx: added latex preamble for hyperref package.
5678 Using pdflatex this will give you a hyperlinked pdf file with
5679 bookmarks. (prepend '%' before /usepackage if this breaks something)
5681 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5691 * src/SDCCglue.c (printIval): fixed bug #739934
5693 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
5695 Applied patch from bug 737905 (renamed yylineo to mylineno):
5702 * src/pic16/pcode.c: Cleaned warnings
5703 * src/pic16/pcodeflow.c: Cleaned warnings
5704 * src/pic16/pcoderegs.c: Cleaned warnings

5717 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5719 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5720 it can be defined with CFLAGS when running configure
5721 * src/SDCCmain.c: fixed compiling + linking with object files
5723 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5725 * configure.in: configure for pic16 port,
5726 added --disable-pic16-port
5727 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5728 * src/SDCCmain.c: linkOptions is changed to set *,
5729 added if/endif conditional macros to remove options help
5730 messages from optionsTable when a port is not configured, added
5731 support for the PIc16 port in the ports table, when executing
5732 the compiler with no port specified on command line, a default
5733 port is selected with the new macro DEFAULT_PORT which is
5734 defined in port.h, in setDefaultOptions() linkOptions is removed
5735 from initialization assignment, since now it is a set,
5736 parseCmdLine uses setParseWithComma for linkOptions, in
5737 linkEdit() linkOptions are accessed with new function indexSet()
5738 which returns the i'th item of a set variable. See SDCCset.c, in
5739 linkEdit() when calling buildCmdLine(), added linkOptions as
5740 last argument. Now users can pass arguments to gplink via the
5741 -Wl option, main() uses pic16glue() to glue up pic16 programs
5742 * src/SDCCpeeph.c: various changes to support pic16
5743 * src/SDCCset.c: added function void *indexSet(set *, int) to

5751 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5753 * src/pic16/glue.c: commented out some error producing lines
5754 * src/pic16/main.c: __config directives are commented out to stop
5755 gpasm complaining and test the linkage with gplink, _linkCmd and
5756 _asmCmd changed to be more gplink and gpasm friendly
5757 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5758 produced an error when parsed, peep rule 12 is added to utilize
5759 movff, but it is commented out since the pCode does not support
5760 yet a command with 2 address arguments
5762 2003-05-18 <johan AT balder>
5764 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5765 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5789 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5791 2003-05-11 Borut Razem <borut.razem AT siol.net>
5793 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5794 the path of bin directory, so that PATH is the only env. variable, which has to be set
5795 in case of standard installation.
5796 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6799 * src/SDCCicode.c: fixed array add
6801 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6802 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6803 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6805 2003-01-04 <johan AT balder>
6807 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6809 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6810 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6812 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6813 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6820 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6822 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6823 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6825 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6827 * in \sdcc\as\mcs51\ changed these files in order to create an
6828 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6829 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6830 following files to include the previous two files: aslink.dsp,
6831 Makefile.aslink, Makefile.bcc, and Makefile.in.
6833 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6834 .adb instead of .cdb
6836 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6838 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6839 value from option --iram-size.
6841 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6843 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6846 2002-09-18 <wiml AT hhhh.org>
6848 * SDCClrange.h: exposed setFromRange() and setToRange()
6849 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6850 packRegsForAccUse() (bug 542397)
6851 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6852 multiple times and emitting the fetch operations more than once
6853 added aopGetUsesAcc() function to allow binary operators to
6854 fetch their operands in the correct order; made genMinus() emit
6855 compact code for X = LITERAL - Y
6857 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6858 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6859 sprintf() in line 1267.
6861 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6862 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6865 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6866 Changes to aslink (All the changes are marked with 'JCF'):
6868 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6871 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6872 area BSEG. Also moves, if possible, the DATA area down into the internal
6873 ram so more space is available.
6875 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6878 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6879 not bytes. Function summary() which creates a memory usage summary
6880 file with extension .mem. Reports of overlaping stack and small stack
6881 size. If the space for the stack is less than 16 bytes aslink trows a
6884 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6885 the 8051. Option 'y' for memory summary output file.
6887 Changes to sdcc (All the changes are marked with 'JCF'):
6889 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6891 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6892 overlaying area for it (uses RegBankUsed[4]).
6894 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6895 bank zero as used by default. By default aslink locates the stack
6896 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6897 the creation of the .mem file. Delegates the allocation of data area
6898 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6899 the begining of the stack area to aslink.
6901 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6902 glue() in SDCCglue.c creates an area for it.
6904 2002-09-03 Borut Razem <borut.razem AT siol.net>
6905 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6906 sdcc/src/pic/glue.c:
6907 introduced atexit() handler for teporay files removal in case of
6908 errors, assertions, ...
6910 2002-08-29 Borut Razem <borut.razem AT siol.net>
6911 * sdcc/support/cpp2/auto-host_vc_in.h:
6912 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6913 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6914 Maybe there is a similar problem with BORLANDC? It should be checked!
6916 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6917 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6918 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6919 was not executed, and the compiler (cl) launched a warning:
6920 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6922 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6923 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6925 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6926 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6928 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6929 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6932 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6933 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6934 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6935 - added Release configuration in VS projects
6936 - review of compiler an linker options
6937 - VC .exe files are generated in bin_vc directory, not to interfere
6938 with binaries generated from other projects (cygwin, mingw, bcc ...)
6940 * sdcc/src/yacc.dsp: added
6942 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6943 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6944 and insert the version number definitions from .version
6946 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6948 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6949 added - genarate auto-host.h using auto-host_vc_in.h as template
6952 removed from CVS, generated automatically
6954 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6955 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6957 2002-08-11 Borut Razem <borut.razem AT siol.net>
6958 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6960 2002-08-10 Borut Razem <borut.razem AT siol.net>
6961 * src/SDCCmain.c (main):
6962 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6963 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6964 The consequence was that some temporary files were not removed.
6967 unification of code in functions tempfilename() and tempfile():
6968 function tempnam() is defined in Visual Studio 6.0 and .NET
6970 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a

7175 * sdcc/src/SDCCloop.c:
7176 Previous fix was not good. basic blocks that have "break" or "return" are
7177 not really partof a loop , but live ranges used in these blocks should
7178 be live thru the entire loop, so set partOfLoop but don't add them to
