465 (setFromConditionArgs): friendly operand parser for peephole rules,
466 (operandBaseName, operandsNotRelated): new peephole condition
467 "operandsNotRelated" -- similar to "operandsNotSame", but takes
468 architecture specific register naming into account, handles n-way
469 comparisons, and supports quoted literals

480 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
482 Adding support for replacing ljmps with sjmps in jumptables
483 generated for switch statements. For now you need to set the
484 environment variable SDCC_SJMP_JUMPTABLE to enable this.
485 Now 4 algorithms for mcs51 jumptable generation are used:
486 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
487 addresses loaded pc-relative for up to 112 cases and stack-pushing
488 target addresses loaded with offset from dptr for up to 256 cases.

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

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

548 bits with offset (case PO_GPR_BIT),
549 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
551 * (isBankInstruction): modified to return 0 for no banking instruction,
552 and 1 for banking instruction,
553 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
554 caused stop processing pCodes after a inline assembly block,
555 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
556 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
557 registers when it shouldn't,
558 * src/pic16/ralloc.c (allocReg): add preliminary support for
559 supporting a limited set of temporary registers,
561 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
563 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
564 genDataPointerSet): ensure assignments always copy in MSB to LSB
566 (loadRegFromAop): recognize CLRH optimization,
567 (genFunction): optimize RECEIVE iCodes in reentrant functions
569 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
571 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
572 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
574 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
575 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be

3569 loaded with the linker search paths (-L arguments) and the libraries
3570 to be linked with the current source (-l arguments). Changes
3571 currently will affect only the pic16 port.
3572 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3573 include path the port specific paths and port specific libraries,
3574 * gplink command now contains the $3 argument,

3579 * src/pic16/glue.c (pic16glue): corrected bug with code
3580 initialization which bypassed the variable initializations block.
3582 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3583 COMPILE_FLAGS and added the --nostdinc option
3585 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3587 * device/include/mc68hc908jb8.h: Register defs for another member

3592 Documenting changes from previous commits.
3593 * configure.in (version 1.56),
3594 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3595 when generating output files to configure the pic16 library,
3596 but now I've commented it out, since gputils aren't installed in the
3597 SF compile farm, so library won't compile
3599 * device/lib/Makefile.in (version 1.56): initially I've added in
3600 target 'all' the prerequestive 'model-pic16' so it compiled the
3601 pic16 library, but now I've commented it out for the same reasons
3603 * added targets 'model-pic16' and 'objects-pic16' to compile the
3605 * added target 'port-specific-objects-pic16' to handle the
3606 generated libraries and copy them into the build/ directory
3607 * added target 'clean-intermediate-pic16' to clean intermediate
3608 files into pic16 directory
3609 * in target 'installdirs' added line to create directory pic16 in
3610 the installation path
3612 * device/include/Makefile.in (version 1.11): in target 'install'
3613 added lines to copy all header files to installation path,
3614 * in target 'installdirs' added line create directory for pic16
3615 headers in the installation path
3617 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3630 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3631 option so that it actually works. Made it specific to the z80, since
3632 the gbz80 doesn't have these kinds of I/O ports.
3634 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3636 * device/include/z180.h,

3649 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3651 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3652 changed interrupt vector table generation to only emit declared vectors.

3658 Mainly changes to support compilation of the device libraries
3659 * src/pic16/device.c: stack is allocated via symbol and not
3660 via literal number. The symbol is placed in the corresponding
3661 position of the data ram
3662 * (pic16_dump_section): relocatable and absolute uninitialized
3663 data are now emitted in sorted order to reduce section naming,
3664 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3665 weren't marked as being in the access bank,
3667 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3669 Added portion of GNU PIC Library under the directory
3670 device/include/pic16 and device/lib/pic16. These files
3671 contain the declarations of SFRs for the PIC18Fxx2 devices.
3672 The directory is initialized via configure from toplevel.
3674 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3676 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3677 the spilllocations to be compared correctly

3701 * doc/sdccman.lyx: Moved and added some sections, small changes
3702 all over. Telling LaTeX to be less strict with word spacing
3703 to better keep the right margin. Changed some notes about
3704 maintainance of the ports in section 3.2.1 - is it OK like this?
3706 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3743 UPPER for immediate operands,
3744 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3746 * src/pic16/peeph.def: all peepholes with movff are commented out,
3747 because there is a problem in the pcode peep optimizer,
3748 * src/pic16/ralloc.c: the register allocator can now reuse local
3749 function symbols for another function. This saves register usage.
3750 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3752 Added file src/pic16/NOTES with information about program writing on
3753 the current port version.

3785 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3788 * src/z80/main.c: added missed needLinkerScript flags (more than
3789 one port structure defined in these file)
3790 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3812 * (pic14emitOverlay): modified to emit a commented overlay segment
3813 directive when no overlay data exist
3814 * (picglue): modified to emit uninitialized data segment
3815 according to udata_section_name

3825 2004-01-07 Borut Razem <borut.razem AT siol.net>
3827 * support/scripts/sdcc.nsi: update PATH
3828 * support/scripts/sdcc.ico: craeted

3841 include information about variables allocated to the overlay
3844 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3846 * as/mcs51/lkmain.c: Help about -Y option

3858 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3860 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3861 (default behaviour).
3863 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3865 A python script to validate compiler diagnostic messages. It can be
3866 used to verify that sdcc complains about bad c source code and
3867 gives a good location of the error.
3868 * support/valdiag/Makefile,
3869 * support/valdiag/valdiag.py,
3870 * support/valdiag/tests/*
3872 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3887 Bug reported from Jesus Calvino-Fraga
3889 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3891 * sdcc.spec: updated
3892 * device/include/Makefile.in: don't install CVS directories
3893 * device/lib/Makefile.in: added removal of CVS directories after install
3894 * doc/Makefile: fixed install, added local_icons
3895 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3896 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3897 * src/ds390/gen.c (genRightShift): fixed bug #870788
3898 * src/SDCCast.c (decorateType): fixed bug #870781
3900 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3902 PIC16 port related changes:
3903 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3904 added variable stackPos,
3906 * gen.c: genCall, assignResultValue: added support for
3907 pushing/retrieving function parameters to/from stack,
3908 genFunction,genEndFunction: setup stack frame for the
3910 genAddrOf: will be changed according to bug 863624
3912 * added files genutils.c and genutils.h which contain gen*
3913 debugged and optimised functions extracted from gen.c
3915 * glue.c: added variable 'externs' which holds extern symbols,
3916 pic16emitRegularMap: is modified to properly handle relocatable
3917 symbols under the new scheme,
3918 pic16createInterruptVect: is modified
3919 pic16printPublics: is modified to emit 'global' assembler directives,
3920 added pic16_printExterns to print extern symbols,
3921 pic16glue: initializes stack/frame pointer in the beginning of
3922 the assembly output. Temporary hack, will be corrected later,
3923 because gplink yet does not support stack and SDCC does not
3924 yet support a type of crt0.o object to create the final binary.
3926 * Removed many lines that contain 8051 legacy code.
3927 * The code is finally placed under a 'code' directive.
3928 * Added port specific options.
3930 * _process_pragma: simplified since now we do not need *special*
3931 include file to define SFR registers. But a separate header
3932 will be needed. This will be developed later.
3933 * _pic16_parseOptions: added, parses port specific options:
3934 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3935 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3936 --preplace-udata-with=
3938 * _pic16_setDefaultOptions: modified to initialize section names,
3939 but hack is temporarly out of order since it needs improvement.
3940 * _pic16_genAssemblerPreamble: configuration words are emitted by
3941 their address instead of their name. This part is incomplete and
3942 supports only the 18Fxx2 devices. Other devices will emit an error
3943 during assembly since they do not contain the same set of config
3945 * _pic16_genIVT: is modified,
3947 * pcode.c: added definitions for some hardware registers that are needed
3949 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3950 All PCI entries are updated. Now LFSR is supported.
3951 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3952 * added pic16_newpCodeOpLit2 to support instructions with
3953 two literal arguments
3954 * pic16_pCode2str: corrected code that emits assembler instructions
3955 with two literal operands and those that have an access bit modifier
3956 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3957 this fixes a bug which caused some labels to be lost, when an
3958 assembler directive was added, i.e. banksel,
3959 * pic16_FixRegisterBanking: improved logic that causes the insertion
3961 * InlineFunction: functions that are called once, are not any more
3962 inlined. This can be a port option in the future,
3964 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3966 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3967 hold the corresponding uninitialized symbols,
3968 * pic16_allocProcessorRegister: registers have explicit marked the
3970 * pic16_allocInternalRegister: registers are explicit marked as
3972 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3973 processing list, so bit registers were lost,
3976 * ralloc.h: added field 'accessBank' and original symbol operand
3977 in register definition,
3978 * removed the field isMapped from register definition,
3980 ** Several functions have been removed from various sources:
3981 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3982 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3983 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3984 pic16_assignRelocatableRegisters
3986 ** others have been introduced:
3987 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3988 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3990 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3992 * support/scripts/inc2h.pl: changed definition of BIT_AT
3993 to emit 'sbit at' instead of 'bit at'. This was a request.
3995 PIC16 port related preliminary changes:
3996 * gen.c: prefixed function popRegFromString with
3997 pic16_ and all references to it corrected
3998 * pcode.c: all pic16_pc_* hardware registers prefixed
3999 with underscore (_),
4000 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4001 * ralloc.c: newReg(): when register is REG_SFR then
4002 set address to rIdx,
4003 pic16_allocProcessorRegister(): marks register wasUsed=0
4004 pic16_writeUsedRegs(): added a call to assign processor
4005 registers via pic16_assignFixedRegisters
4007 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4009 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4010 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4011 variables in unused register banks. Also the SSEG is placed
4012 wherever there is enough space for it, and IDATA can be anywhere
4013 in internal RAM. For now compile using -Wl-Y[stack_size].
4014 The mem file is different for this option as well, since it
4015 makes no sense of talking about DSEG lenght.
4017 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4019 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4020 in certain cases, e.g. when ROM assignment, patch provided
4021 from Albert den Haan.
4023 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5066 A few small changes that speed up the peephole optimizer.
5070 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5072 Try to make the peephole optimizer smarter by maintaining
5073 an association between the assembly source code and the
5074 iCodes that originated them. Put this information to use
5075 with a new peephole rule condition "notVolatile" so that
5076 the rules can be aggressive yet still safe.
5081 * src/mcs51/peeph.def
5083 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5087 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5088 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5089 if the left or right operand symbols have the accuse flag set.
5091 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5093 Changed the type of the result of the ! (NOT) operator to char;
5094 previously it returned the same type as the source. This allows
5095 us to eliminate all the genFloatNot functions (all of its target
5096 implementations were very buggy) since !float can use the same
5099 * src/SDCCicode.c (ast2iCode): ! returns char
5100 * src/mcs51/gen.c (genNot, genNotFloat),
5101 * src/ds390/gen.c (genNot, genNotFloat),
5102 * src/z80/gen.c (genNot, genNotFloat),
5103 * src/pic/gen.c (genNot, genNotFloat),
5104 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

5108 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5109 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5110 during interrupts. Ensure WSAVE is located at a shared bank address.
5111 2. Fixed page selection in some places
5112 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5113 the registers name strings.
5114 4. Fixed "signed / unsigned compare" compiler warnings.
5115 5. The PIC port manages its own allocation of the general purpose
5116 registers, but makes no attempt to reuse them. As a result when
5117 compiling it soon runs out of general purpose registers. Some
5118 additional code was added to the files pcode.c and device.c to walk
5119 through the function call tree and rename the registers so that they
5129 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5130 genPlus() & genMinus() when the result is the same as left or right

5136 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5138 Made bitfield a distinct type from bit so that bitfields
5139 convert as per ANSI C and bits retain their traditional
5140 boolean style behaviour. Implemented bitfield support in
5148 * src/ds390/gen.c: bit v bitfield split
5149 * src/z80/gen.c: New support for bitfields
5150 * support/regression/tests/bitfields.c: reenabled z80,
5153 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5155 Rules 246.x, 247.x relate to bitfields, the others speed up
5156 access to xdata mapped I/O devices.
5158 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5160 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5162 Cleaned up genPackBits and genUnpackBits and added two helper
5163 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5164 for literal assignments in genPackBits (thanks to Frieder for
5170 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5172 Fixed bug #748310 (pointer to function type mishandled when the
5173 function name is omitted). Also fixed a SIGSEGV when a function
5174 attribute (reentrant, etc) is used on a non-function or on a
5175 function but misplaced before the parameter list.
5177 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5179 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5202 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5204 Made the constant following the "interrupt" keyword optional. If
5205 omitted, the function will not automatically be given an entry
5206 in the interrupt vector table (similar to #pragma NOIV, but
5207 less syntacticly kludgy). The interrupt number is also now
5208 range checked. Also fixed a bug in the high order bit example

5224 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5226 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5227 be re-activated by defining REDUCE_LITERALS)

5229 unsigned, but are signed by default
5230 * src/SDCCval.c (constVal): rearranged
5231 * src/SDCCval.c (valMod): preliminary fix
5232 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5674 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5676 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
5677 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5678 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5679 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5682 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5684 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5685 the regression tests I'm not brave enough to enable 245.b, 245.c
5686 * doc/sdccman.lyx: added latex preamble for hyperref package.
5687 Using pdflatex this will give you a hyperlinked pdf file with
5688 bookmarks. (prepend '%' before /usepackage if this breaks something)

5700 * src/SDCCglue.c (printIval): fixed bug #739934
5702 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
5704 Applied patch from bug 737905 (renamed yylineo to mylineno):
5711 * src/pic16/pcode.c: Cleaned warnings
5712 * src/pic16/pcodeflow.c: Cleaned warnings
5713 * src/pic16/pcoderegs.c: Cleaned warnings

5726 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5728 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5729 it can be defined with CFLAGS when running configure
5730 * src/SDCCmain.c: fixed compiling + linking with object files
5732 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5734 * configure.in: configure for pic16 port,
5735 added --disable-pic16-port
5736 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5737 * src/SDCCmain.c: linkOptions is changed to set *,
5738 added if/endif conditional macros to remove options help
5739 messages from optionsTable when a port is not configured, added
5740 support for the PIc16 port in the ports table, when executing
5741 the compiler with no port specified on command line, a default
5742 port is selected with the new macro DEFAULT_PORT which is
5743 defined in port.h, in setDefaultOptions() linkOptions is removed
5744 from initialization assignment, since now it is a set,
5745 parseCmdLine uses setParseWithComma for linkOptions, in
5746 linkEdit() linkOptions are accessed with new function indexSet()
5747 which returns the i'th item of a set variable. See SDCCset.c, in
5748 linkEdit() when calling buildCmdLine(), added linkOptions as
5749 last argument. Now users can pass arguments to gplink via the
5750 -Wl option, main() uses pic16glue() to glue up pic16 programs
5751 * src/SDCCpeeph.c: various changes to support pic16
5752 * src/SDCCset.c: added function void *indexSet(set *, int) to

5762 * src/pic16/glue.c: commented out some error producing lines
5763 * src/pic16/main.c: __config directives are commented out to stop
5764 gpasm complaining and test the linkage with gplink, _linkCmd and
5765 _asmCmd changed to be more gplink and gpasm friendly
5766 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5767 produced an error when parsed, peep rule 12 is added to utilize
5768 movff, but it is commented out since the pCode does not support
5769 yet a command with 2 address arguments
5771 2003-05-18 <johan AT balder>
5773 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5774 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5775 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

5798 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5800 2003-05-11 Borut Razem <borut.razem AT siol.net>
5802 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5803 the path of bin directory, so that PATH is the only env. variable, which has to be set
5804 in case of standard installation.
5805 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6812 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6814 2003-01-04 <johan AT balder>
6816 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6818 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6819 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6821 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6822 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6831 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6832 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6834 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6836 * in \sdcc\as\mcs51\ changed these files in order to create an
6837 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6838 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6839 following files to include the previous two files: aslink.dsp,
6840 Makefile.aslink, Makefile.bcc, and Makefile.in.
6842 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6843 .adb instead of .cdb
6845 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6847 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6848 value from option --iram-size.
6850 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6852 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6855 2002-09-18 <wiml AT hhhh.org>
6857 * SDCClrange.h: exposed setFromRange() and setToRange()
6858 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6859 packRegsForAccUse() (bug 542397)
6860 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6861 multiple times and emitting the fetch operations more than once
6862 added aopGetUsesAcc() function to allow binary operators to
6863 fetch their operands in the correct order; made genMinus() emit
6864 compact code for X = LITERAL - Y
6866 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6867 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6868 sprintf() in line 1267.
6870 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6871 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6874 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6875 Changes to aslink (All the changes are marked with 'JCF'):
6877 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6880 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6881 area BSEG. Also moves, if possible, the DATA area down into the internal
6882 ram so more space is available.
6884 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6887 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6888 not bytes. Function summary() which creates a memory usage summary
6889 file with extension .mem. Reports of overlaping stack and small stack
6890 size. If the space for the stack is less than 16 bytes aslink trows a
6893 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6894 the 8051. Option 'y' for memory summary output file.
6896 Changes to sdcc (All the changes are marked with 'JCF'):
6898 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6900 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6901 overlaying area for it (uses RegBankUsed[4]).
6903 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6904 bank zero as used by default. By default aslink locates the stack
6905 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6906 the creation of the .mem file. Delegates the allocation of data area
6907 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6908 the begining of the stack area to aslink.
6910 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6911 glue() in SDCCglue.c creates an area for it.
6913 2002-09-03 Borut Razem <borut.razem AT siol.net>
6914 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6915 sdcc/src/pic/glue.c:
6916 introduced atexit() handler for teporay files removal in case of
6917 errors, assertions, ...
6919 2002-08-29 Borut Razem <borut.razem AT siol.net>
6920 * sdcc/support/cpp2/auto-host_vc_in.h:
6921 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6922 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6923 Maybe there is a similar problem with BORLANDC? It should be checked!
6925 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6926 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6927 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6928 was not executed, and the compiler (cl) launched a warning:
6929 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6931 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6932 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6934 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6935 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6937 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6938 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6939 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6940 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6941 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6942 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6943 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6944 - added Release configuration in VS projects
6945 - review of compiler an linker options
6946 - VC .exe files are generated in bin_vc directory, not to interfere
6947 with binaries generated from other projects (cygwin, mingw, bcc ...)
6949 * sdcc/src/yacc.dsp: added
6951 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6952 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6953 and insert the version number definitions from .version
6955 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6957 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6958 added - genarate auto-host.h using auto-host_vc_in.h as template
6961 removed from CVS, generated automatically
6963 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6964 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6966 2002-08-11 Borut Razem <borut.razem AT siol.net>
6967 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6969 2002-08-10 Borut Razem <borut.razem AT siol.net>
6970 * src/SDCCmain.c (main):
6971 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6972 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6973 The consequence was that some temporary files were not removed.
6976 unification of code in functions tempfilename() and tempfile():
6977 function tempnam() is defined in Visual Studio 6.0 and .NET
6979 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6981 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6982 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6983 - removed compiler command line option /WX: Treats all warnings as errors
6984 - update a list of source files, included into the project
6986 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

6997 added return 0 statements after assert() to make compiler happy
6999 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7000 added newline in the def file to keep MSC compiler satisfied
7002 * sdcc/src/z80/gen.c:
7003 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7004 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7005 - solved MSC error in function aopDump()
7007 * sdcc_vc.h: define PREFIX as "\\sdcc"

7184 * sdcc/src/SDCCloop.c:
7185 Previous fix was not good. basic blocks that have "break" or "return" are
7186 not really partof a loop , but live ranges used in these blocks should
7187 be live thru the entire loop, so set partOfLoop but don't add them to
