[fw/sdcc] / ChangeLog

2005-01-24 Vangelis Rokas <vrokas AT otenet.gr>

        * device/lib/pic16/libm: added Math library sources

2005-01-24 Raphael Neider <rneider AT web.de>

        * src/pic16/pcode.h: added second memory operand to pCodeOpReg
          to enable upcast to pCodeOpReg2 (there is no type tag to
          differenciate the two and pic16_popGet2p cast into PCOR2)
        * src/pic16/main.c (_process_pragma): fixed another malloc bug
          (sizeof(sectNames) changed to sizeof(sectName))
          Both patches fix segfaults under MinGW.

2005-01-23 Raphael Neider <rneider AT web.de>

        * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
          Safe_[mc]?alloc()'ed variables
        * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
          of (byte sized) temporaries (assign them to WREG for now)
        * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
          (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
          this might fix SIGSEGVs on MinGW...
        * src/SDCCopt.c (killDeadCode): restored original behaviour
          (volatile operands might get thrown away though)

2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

        * src/pic16/gen.c: fixed bug #1106975,
        * src/pic16/gen.c: fixed possible bug #1102572, now during TOS
        pointer update, INTCON is saved, global interrupts are disabled and
        restored after updateing TOS.
        * src/SDCC.y, src/SDCC.lex, src/SDCCsymt.c, src/SDCCsymt.h:
        * added function attribute 'shadowregs' to take advantage of shadow
        registers,
        * added function attribute 'wparam' as an alternative to the wparam
        pragma,
        * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
        user declares a non-ISR function as 'shadowregs',

        function,
        * doc/sdccman.lyx: updated to reflect new changes,
        * src/pic16/gen.c (aopForSym): don't handle sym->iaccess in
        sym->onStack if-case,
        * src/pic16/main.c (_pic16_keywords): commented out keywords bit,
        sbit, idata, _idata, xdata, _xdata,
        * added pragma library, to link an external library, (see doc),
        * removed command line options, --pomit-config-words, --pomit-ivt,
        --pleave-reset-vector,
        * (pic16_finaliseOptions): when define macro SDCC_MODEL_{SMALL/LARGE}

2005-01-19 Raphael Neider <rneider AT web.de>

        * src/SDCCglobl.h: ensure that PATH_MAX >= 2048 to guarantee
          cmdLine buffers (used when calling sdcpp...) are large enough
          (MAX_PATH=256 truncates arguments leading to system halts when
          used in MinGW...)
        * src/pic16/gen.c (pic16_sameRegs): relaxed size criterion
        * (genUminus): rewritten to for efficiency
        * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
          used uninitialized in some cases)
        * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
          copy the third byte from the int -- now assumes 0x80 (data memory)
        * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
          operands (genAddLit expects the iCode's operands to swapped as
          well), fixed leftover bytes (crashed for short left operands)

          PIC14 emitSKPNCs
        * (pic16_genMinus): fixed to cope with differently sized operands
        * src/pic16/glue.c (pic16_glue): added new banksel optimization
          for --obanksel > 1
        * src/pic16/pcode.c: implemented (first phase of) banksel optimization
        * src/pic16/graph.[ch]: implementation of directed graphs, used by
          new banksel optimization
        * src/pic16/pcoderegs.c (pCodeRegMapLiveRangesInFlow): prevented
          analysis for temporary registers (segfaults...)
        * src/pic16/peeph.def: added rule

2005-01-18 Vangelis Rokas <vrokas AT otenet.gr>

        * device/lib/pic16/libc/stdlib/x_ftoa.c: it defines x_ftoa function
        which converts a float number to its ASCII representation
        * device/lib/pic16/libc/utils/cnvfrac.S,cnvint.S: support
        functions to convert the fractional and integer part of a float to ASCII,

        a pCodeOp as tested operand,
        * (genNearPointerGet): optimized bit testing, does not use
        intermediate register for bit value, test directly instead with
        BTFSS, BTFSC, works only for single bits,
        * (genpic16Code): dump the name of the iCode in the asm,
        * src/pic16/ralloc.c (decodeOp): removed static declaration and
        renamed to pic16_decodeOp,

        * src/pic16/pcode.[ch]: introduced pic16_stackpnt_*,
        pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
        access stack and frame pointers. They are initially assigned to
        point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
        accessing SFRs. Updated all occurences of modification of stack or

        * src/pic16/gen.c (genIfxJump): fixed inverted skips on CARRY
        * (genIfx): fixed (?) read from uninitialized SPIL_LOC (now assumes CARRY
          to hold the condition bit)
        * added new version of genCmp (old code available via #define)
        * added new version of genShiftLeft/genShiftRight in a generic
          way, now supports shifting by negative values
        * (genLeftShiftLiteral, genRightShiftLiteral): use absolute value of

        * src/pic16/pcode.c (pic16_OptimizeJumps): removed annoying statistics
          dump
        * (pic16_newpCodeOpLit): changed to cast to unsigned char (as e.g. -32766
          is an invalid literal too...)

2005-01-04 Vangelis Rokas <vrokas AT otenet.gr>

        * src/pic16/gen.c (aopForSym, genEndFunction): applied some fixes
        from Raphael Neider,
        * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
        for 8-bit literals. This fixes some literal operands which are sign
        extended to 16-bits ints when instruction needs only 8-bits.

2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

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

        * src/SDCCpeeph.c: added peephole conditional labelJTInRange
        * src/mcs51/main.c: adapted constants for switch table generation
        * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>

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

        * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
        * src/pic16/gen.c (aopForRemat): asmop size is filled by
        aopForRemat() now and not by pic16_aopOp(),
        * (pic16_popGetTempReg): removed warning messgae when allocating
        temporary registers, its a buggy feature and will be removed,
        * (pic16_popGet): set register instance field in AOP_CRY,
        * (pic16_outBitC): fixed for results in size greater than 1,
        * (genUminusFloat): fixed for pic16, ported code from mcs51,
        * (pic16_storeForReturn): optimized return of 0,
        * (genCmp): experimental code for new genCmp which uses PIC18's
        special compare&skip instructions. Initial tests fail some times
        with variables grater than 1 byte in size, so new code is disabled,
        * (genUnpackBits, genPackBits): more optimizations in reading/writing,
        a single bit,
        * (genCast): began a fix to optimize the casting of a bit to another
        bit, now assigning a bitfield to another bitfield will fail, sorry,
        * src/pic16/main.c: disabled the use of lr-support feature,
        * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
        * added some function prototypes, added function _debugf prototype,
        * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
        bits with offset (case PO_GPR_BIT),
        * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
        command line,
        * (isBankInstruction): modified to return 0 for no banking instruction,
        and 1 for banking instruction,
        * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
        caused stop processing pCodes after a inline assembly block,
        * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
        * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
        registers when it shouldn't,
        * src/pic16/ralloc.c (allocReg): add preliminary support for
        supporting a limited set of temporary registers,

2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
          genDataPointerSet): ensure assignments always copy in MSB to LSB
          order,
          (loadRegFromAop): recognize CLRH optimization,
          (genFunction): optimize RECEIVE iCodes in reentrant functions

2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
          --out-fmt-s19 turning into --out-fmt-elf if s19 was already
          selected.
        * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
        * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
          contiguous with data

2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

        * device/lib/_gptrgetc.c (_gptrgetc),
        * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
          instead of sjmp to ret
        * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
          by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

        loaded with the linker search paths (-L arguments) and the libraries
        to be linked with the current source (-l arguments). Changes
        currently will affect only the pic16 port.
        * src/pic16/main.c (_pic16_finaliseOptions): add to the linker

        to Pics16. Updated all references to them.
        * src/pic16/glue.c (pic16glue): corrected bug with code
        initialization which bypassed the variable initializations block.

        * device/lib/pic16/Makefile.rules: removed --penable-stack from
        COMPILE_FLAGS and added the --nostdinc option

2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * device/include/mc68hc908jb8.h: Register defs for another member
        of the hc08 family. Contributed by Bjorn Bringert - thanks!

2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>

        Documenting changes from previous commits.
        * configure.in (version 1.56),
        * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
        when generating output files to configure the pic16 library,
        but now I've commented it out, since gputils aren't installed in the
        SF compile farm, so library won't compile

        * device/lib/Makefile.in (version 1.56): initially I've added in
        target 'all' the prerequestive 'model-pic16' so it compiled the
        pic16 library, but now I've commented it out for the same reasons
        above,
        * added targets 'model-pic16' and 'objects-pic16' to compile the
        library
        * added target 'port-specific-objects-pic16' to handle the
        generated libraries and copy them into the build/ directory
        * added target 'clean-intermediate-pic16' to clean intermediate
        files into pic16 directory
        * in target 'installdirs' added line to create directory pic16 in
        the installation path

        * device/include/Makefile.in (version 1.11): in target 'install'
        added lines to copy all header files to installation path,
        * in target 'installdirs' added line create directory for pic16
        headers in the installation path

2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

        * src/ds390/gen.c (genCall): fixed a double use of acc and b after
         a function call

2004-01-13 Bernhard Held <bernhard AT bernhardheld.de>

        * configure,
        * device/lib/configure.in,
        * device/lib/configure: fixed for autoconf 2.57

2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/z80/main.c (_parseOptions): fixed the portmode= command line
        option so that it actually works. Made it specific to the z80, since
        the gbz80 doesn't have these kinds of I/O ports.

2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * device/include/z180.h,
        * device/lib/_memcpy.c,
        * device/lib/_memmove.c,
        * device/lib/_mulint.c,
        * device/lib/ser_ir.c,
        * device/lib/ser_ir_cts_rts.c,
        * device/lib/_strcmp.c,
        * device/lib/_strtok.c: fixed pragmas to non-deprecated form
        * src/z80/main.c (_process_pragma): add support for pragmas bank and
        portmode; added deprecation warning for bank= and protmode= forms.
        Also, guard against buffer overflow.
        * src/z80/gen.c (aopGet): generate better code for sfr banked read

2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
        changed interrupt vector table generation to only emit declared vectors.
        * device/include/Makefile.in: added missing backslash
        * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

        Mainly changes to support compilation of the device libraries
        * src/pic16/device.c: stack is allocated via symbol and not
        via literal number. The symbol is placed in the corresponding
        position of the data ram
        * (pic16_dump_section): relocatable and absolute uninitialized
        data are now emitted in sorted order to reduce section naming,
        * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
        weren't marked as being in the access bank,

2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

        Added portion of GNU PIC Library under the directory
        device/include/pic16 and device/lib/pic16. These files
        contain the declarations of SFRs for the PIC18Fxx2 devices.
        The directory is initialized via configure from toplevel.

2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

        * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
        the spilllocations to be compared correctly

2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

        * src/SDCCast.c (decorateType): fixed bug introduced today

2004-01-12  Borut Razem <borut.razem AT siol.net>

        * src/SDCCast.c (decorateType): replacing 'ul > 0' by  '!ul' results
        in simpler and even better code

2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>

        * src/SDCCicode.c (operandOperation): fixed bug #874819
        * src/SDCCast.c (decorateType): fixed
        char foo (unsigned long ul) { return ul > 0; }

2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

        * doc/sdccman.lyx: Moved and added some sections, small changes
        all over. Telling LaTeX to be less strict with word spacing
        to better keep the right margin. Changed some notes about
        maintainance of the ports in section 3.2.1 - is it OK like this?

2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

        SDCC source changes:
        * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
        convilong): modified to inform the pic16 port that builtin functions
        are external

        PIC16 PORT specific changes:
        * src/pic16/device.c pic16_dump_equates() added,
        processor registers declared internally by the port are emitted in
        the translation as equates,
        * src/pic16/gen.c: inline code is passed unprocessed to the
        translation,
        * (pic16_popGetLit2): fnuction modified to take second operand as
        pCodeOp pointer and not as literal,
        * (popRegFromIdx): prefixed with pic16_,
        * (pic16_popCombine2): modified to receive already allocated pCode
        operands,
        * (pic16_pushpCodeOpReg, pic16_poppCodeOpReg): added
        * (genFunction): initializes local stack frame and pushes on stack
        all the registers used by this function,
        * (genEndFunction): restores all registers from stack and restores
        stack frame,
        * src/pic16/glue.c (pic16emitRegularMap): various changes and
        improvements,
        * (pic16glue): changed the program startup sequence,
        * added new dbName code 'A' for functions placed in absolute section

        * (pic16_newpCodeOpLit2): modified to take the second operand as
        pCodeOp pointer,
        * (pic16_printpBlock): modified to emit each function in a separate
        section,
        * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
        UPPER for immediate operands,
        * src/pic16/pcodepeeph.c: added peephole support for the LFSR
        instruction,
        * src/pic16/peeph.def: all peepholes with movff are commented out,
        because there is a problem in the pcode peep optimizer,
        * src/pic16/ralloc.c: the register allocator can now reuse local
        function symbols for another function. This saves register usage.
        * src/pic16/ralloc.h: added flag isLocal in structure regs,

        Added file src/pic16/NOTES with information about program writing on
        the current port version.

        * src/mcs51/peephole.def: added peepholes 177.c,d (redundant moves)
        and peephole 252 (array access)

2004-01-09  Borut Razem <borut.razem AT siol.net>

        * src/SDCCast.c (decorateType): fixed bug #874046

2004-01-09  Borut Razem <borut.razem AT siol.net>

        * support/scripts/sdcc.nsi: remove previous installation

2004-01-09 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

        * src/SDCCglue.c (createInterruptVect): don't append 7(5) padding
        bytes for last interrupt vector (mcs51)
        * sdcc.spec: fixed typo

2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        ("bug" #845294)

2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/ds390/main.c,
        * src/z80/main.c: added missed needLinkerScript flags (more than
        one port structure defined in these file)
        * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
        bug #795325

2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

        * src/SDCCmain.c: removed various references to DEFAULT_PORT
        * src/port.h: added flag needLinkerScript in port->linker
        structure to inform whether to create a .lnk file or not,
        * src/avr/main.c,
        * src/ds390/main.c,

        * src/z80/main.c: changed appropriately to configure
        needLinkerScript flag
        * src/pic/gen.c,
        * src/pic16/gen.c (genAddrOf): fixed bug #863624
        * src/pic/glue.c: added variable udata_section_name to
        override default uninitialized data segment definition for
        devices only with SHAREBANK memory (reported from Erik Epetrich)
        * (pic14emitOverlay): modified to emit a commented overlay segment
        directive when no overlay data exist
        * (picglue): modified to emit uninitialized data segment
        according to udata_section_name
        * src/pic/main.c (_pic14_parseOptions): added command line

        * modified _linkCmd and _asmCmd to include compiler passed
        arguments via -W option
        * src/pic16/main.c: added $l in _asmCmd, changed extension for
        object file from '.rel' to '.o' in port->linker structure,
        changed size of fptr from 2 to 3 in port structure

2004-01-07  Borut Razem <borut.razem AT siol.net>

        * support/scripts/sdcc.nsi: update PATH
        * support/scripts/sdcc.ico: craeted

2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

        * device/include/Makefile.in: fix install

        include information about variables allocated to the overlay
        segment

2004-01-06  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

        * as/mcs51/lkmain.c: Help about -Y option
        * as/mcs51/lkarea.c: Fixed gcc warnings

2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

        * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
        fixed warning
        * support/valdiag/tests/overflow.c: added
        * src/SDCCast.c (decorateType),
        * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
        LEFT_OP (left shift)

2004-01-06  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

        * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
        (default behaviour).

2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        A python script to validate compiler diagnostic messages. It can be
        used to verify that sdcc complains about bad c source code and
        gives a good location of the error.
        * support/valdiag/Makefile,
        * support/valdiag/valdiag.py,
        * support/valdiag/tests/*

2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
        * src/SDCCsymt.c (newEnumType),
        * src/SDCCsymt.h
        * support/Util/SDCCerr.c,
        * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
        enum related bugs.
        * support/regression/tests/enum.c: added test for enum values that
        require at least 2 bytes of storage.

2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>

        * src/common.h: added ifndef/define/endif macros
        around the header file.
        Bug reported from Jesus Calvino-Fraga

2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

        * sdcc.spec: updated
        * device/include/Makefile.in: don't install CVS directories
        * device/lib/Makefile.in: added removal of CVS directories after install
        * doc/Makefile: fixed install, added local_icons
        * sim/ucsim/gui.src/Makefile.in: fixed an old typo
        * src/mcs51/gen.c (genRightShift): fixed bug #870788
        * src/ds390/gen.c (genRightShift): fixed bug #870788
        * src/SDCCast.c (decorateType): fixed bug #870781

2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>

        PIC16 port related changes:
        * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
        added variable stackPos,

        * gen.c: genCall, assignResultValue: added support for
        pushing/retrieving function parameters to/from stack,
        genFunction,genEndFunction: setup stack frame for the
        generated function,
        genAddrOf: will be changed according to bug 863624

        * added files genutils.c and genutils.h which contain gen*
        debugged and optimised functions extracted from gen.c

        * glue.c: added variable 'externs' which holds extern symbols,
        pic16emitRegularMap: is modified to properly handle relocatable
         symbols under the new scheme,
        pic16createInterruptVect: is modified
        pic16printPublics: is modified to emit 'global' assembler directives,
        added pic16_printExterns to print extern symbols,
        pic16glue: initializes stack/frame pointer in the beginning of
        the assembly output. Temporary hack, will be corrected later,
        because gplink yet does not support stack and SDCC does not
        yet support a type of crt0.o object to create the final binary.

        * Removed many lines that contain 8051 legacy code.
        * The code is finally placed under a 'code' directive.
        * Added port specific options.

        * _process_pragma: simplified since now we do not need *special*
        include file to define SFR registers. But a separate header
        will be needed. This will be developed later.
        * _pic16_parseOptions: added, parses port specific options:
        --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
        --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
        --preplace-udata-with=

        * _pic16_setDefaultOptions: modified to initialize section names,
        but hack is temporarly out of order since it needs improvement.
        * _pic16_genAssemblerPreamble: configuration words are emitted by
        their address instead of their name. This part is incomplete and
        supports only the 18Fxx2 devices. Other devices will emit an error
        during assembly since they do not contain the same set of config
        registers
        * _pic16_genIVT: is modified,

        * pcode.c: added definitions for some hardware registers that are needed
        for stack support
        * added flag is2LitOp and variable pci_magic in pCodeInstruction.
        All PCI entries are updated. Now LFSR is supported.
        * Removed pic16_pciTRIS is mentioned by mdubuc in source
        * added pic16_newpCodeOpLit2 to support instructions with
        two literal arguments
        * pic16_pCode2str: corrected code that emits assembler instructions
        with two literal operands and those that have an access bit modifier
        * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
        this fixes a bug which caused some labels to be lost, when an
        assembler directive was added, i.e. banksel,
        * pic16_FixRegisterBanking: improved logic that causes the insertion
        of bank switching,
        * InlineFunction: functions that are called once, are not any more
        inlined. This can be a port option in the future,

        * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir

        * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
        hold the corresponding uninitialized symbols,
        * pic16_allocProcessorRegister: registers have explicit marked the
        accessBank field,
        * pic16_allocInternalRegister: registers are explicit marked as
        not used,
        * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
        processing list, so bit registers were lost,
        *

        * ralloc.h: added field 'accessBank' and original symbol operand
        in register definition,
        * removed the field isMapped from register definition,

        ** Several functions have been removed from various sources:
        BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
        pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
        isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
        pic16_assignRelocatableRegisters

        ** others have been introduced:
        pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
        pic16_popGetLit2,pic16_popCombine2,pushw,pushaop

2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>

        * support/scripts/inc2h.pl: changed definition of BIT_AT
        to emit 'sbit at' instead of 'bit at'. This was a request.

        PIC16 port related preliminary changes:
        * gen.c: prefixed function popRegFromString with
        pic16_ and all references to it corrected
        * pcode.c: all pic16_pc_* hardware registers prefixed
        with underscore (_),
        pic16_popCopyGPR2Bit(): function sets register wasUsed=1
        * ralloc.c: newReg(): when register is REG_SFR then
        set address to rIdx,
        pic16_allocProcessorRegister(): marks register wasUsed=0
        pic16_writeUsedRegs(): added a call to assign processor
        registers via pic16_assignFixedRegisters

2004-01-04  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

        * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
        as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
        variables in unused register banks.  Also the SSEG is placed
        wherever there is enough space for it, and IDATA can be anywhere
        in internal RAM.  For now compile using -Wl-Y[stack_size].
        The mem file is different for this option as well, since it
        makes no sense of talking about DSEG lenght.

        and restore of EA so that stack offsets to parameters are
        correct when using both critical and reentrant/stack-auto.
        * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
        size (can be triggered in error if sloc is shared between
        different sized objects)
        * device/include/float.h: fixed macros to explicitly use
        unsigned long where needed

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

        pic patch provided by Slade Rich <slade_rich AT yahoo.com>
        * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

        global, which is not permitted in PIC 14 assembly output.

2003-08-23  Frieder Ferlemann <Frieder.Ferlemann AT web.de>

        A few small changes that speed up the peephole optimizer.

        * src/SDCCpeeph.c

2003-08-22  Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        Try to make the peephole optimizer smarter by maintaining
        an association between the assembly source code and the
        iCodes that originated them. Put this information to use
        with a new peephole rule condition "notVolatile" so that
        the rules can be aggressive yet still safe.

        Fixed bug #741761

        * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
        * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
        if the left or right operand symbols have the accuse flag set.

2003-08-20  Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        Changed the type of the result of the ! (NOT) operator to char;
        previously it returned the same type as the source. This allows
        us to eliminate all the genFloatNot functions (all of its target
        implementations were very buggy) since !float can use the same
        code as !long now.

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

        * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454

2003-08-18  Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        Made bitfield a distinct type from bit so that bitfields
        convert as per ANSI C and bits retain their traditional
        boolean style behaviour. Implemented bitfield support in
        the z80 port.

        added more tests

2003-08-17  Frieder Ferlemann <Frieder.Ferlemann AT web.de>

        Rules 246.x, 247.x relate to bitfields, the others speed up
        access to xdata mapped I/O devices.

        * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x

2003-08-16  Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        Cleaned up genPackBits and genUnpackBits and added two helper
        functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
        for literal assignments in genPackBits (thanks to Frieder for
        reminding me).

        * src/ds390/gen.c

2003-08-16  Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        Fixed bug #748310 (pointer to function type mishandled when the
        function name is omitted). Also fixed a SIGSEGV when a function
        attribute (reentrant, etc) is used on a non-function or on a
        function but misplaced before the parameter list.

        * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

        * support/regression/tests/bitfields.c: tests added

2003-08-13  Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        Made the constant following the "interrupt" keyword optional. If
        omitted, the function will not automatically be given an entry
        in the interrupt vector table (similar to #pragma NOIV, but
        less syntacticly kludgy). The interrupt number is also now
        range checked. Also fixed a bug in the high order bit example
        in the manual.

        Hopefully these ones built the librarian and the rest of sdcc properly:
        * Makefile
        * Makefile.common.in

        Messed up 'configure', so revert to previous version:
        * configure
        * configure.in

2003-07-31  Bernhard Held <bernhard AT bernhardheld.de>

        * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
        there, while the mantissa of a double is "only" 53 bits wide.

        * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
          the regression tests I'm not brave enough to enable 245.b, 245.c
        * doc/sdccman.lyx: added latex preamble for hyperref package.
          Using pdflatex this will give you a hyperlinked pdf file with

        * src/SDCCmain.c: fixed compiling + linking with object files

2003-05-18  Vangelis Rokas (vrokas AT otenet.gr)

        * configure.in: configure for pic16 port,
            added --disable-pic16-port
        * sdccconf_in.h: added macro OPT_DISABLE_PIC16
        * src/SDCCmain.c: linkOptions is changed to set *,
            added if/endif conditional macros to remove options help
            messages from optionsTable when a port is not configured, added
            support for the PIc16 port in the ports table, when executing
            the compiler with no port specified on command line, a default
            port is selected with the new macro DEFAULT_PORT which is
            defined in port.h, in setDefaultOptions() linkOptions is removed
            from initialization assignment, since now it is a set,
            parseCmdLine uses setParseWithComma for linkOptions, in
            linkEdit() linkOptions are accessed with new function indexSet()
            which returns the i'th item of a set variable. See SDCCset.c, in
            linkEdit() when calling buildCmdLine(), added linkOptions as
            last argument. Now users can pass arguments to gplink via the
            -Wl option, main() uses pic16glue() to glue up pic16 programs
        * src/SDCCpeeph.c: various changes to support pic16
        * src/SDCCset.c: added function  void *indexSet(set *, int)  to
            return the i'th item of the set
        * src/SDCCset.h: added function prototype for indexSet()
        * src/SDCCsymt.c: in checkSClass(), added support for PIC16

        * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
            added macro DEFAULT_PORT
        * src/pic/main.c: corrected arguments of gplnk in _linkCmd

2002-12-27  Bernhard Held <bernhard AT bernhardheld.de>
        * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o

2002-12-26  Bernhard Held <bernhard AT bernhardheld.de>
        * src/mcs51/main.c: removed {bindir}{sep} from aslink

2002-12-10  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

    * in \sdcc\as\mcs51\ changed these files in order to create an
    aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
    lkmain.c.  Also added: lkmem.c and lkaomf51.c.  Changed the
    following files to include the previous two files: aslink.dsp,
    Makefile.aslink, Makefile.bcc, and Makefile.in.

    * Changed \sdcc\src\SDCCmain.c so it creates files with extension
    .adb instead of .cdb

2002-11-09  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

        * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
        value from option --iram-size.

2002-09-20  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

        * \sdcc\as\mcs51\lklist.c: added boundary check before using
        dram[] array.

2002-09-18    <wiml AT hhhh.org>

        * SDCClrange.h: exposed setFromRange() and setToRange()
        * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
          packRegsForAccUse() (bug 542397)
        * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
          multiple times and emitting the fetch operations more than once
          added aopGetUsesAcc() function to allow binary operators to
          fetch their operands in the correct order; made genMinus() emit
          compact code for X = LITERAL - Y

2002-09-00  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
        * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
        sprintf() in line 1267.

2002-09-08  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
        * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
        like ports.

2002-09-04  Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
        Changes to aslink (All the changes are marked with 'JCF'):

        * \sdcc\as\mcs51\aslink.h: External definition of sflag and
        summary().

        * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
        area BSEG.  Also moves, if possible, the DATA area down into the internal
        ram so more space is available.

        * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
        sflag.

        * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
        not bytes.  Function summary() which creates a memory usage summary
        file with extension .mem.  Reports of overlaping stack and small stack
        size.  If the space for the stack is less than 16 bytes aslink trows a
        warning.

        * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
        the 8051.  Option 'y' for memory summary output file.

        Changes to sdcc (All the changes are marked with 'JCF'):

        * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].

        * \sdcc\src\SDCCglue.c:  If a register bank is used, creates an
        overlaying area for it (uses RegBankUsed[4]).

        * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
        bank zero as used by default.  By default aslink locates the stack
        (equivalent to --stack-after-data).  Pass option 'y' to aslink for
        the creation of the .mem file.  Delegates the allocation of data area
        to aslink (it is not longer 0x30 by default).  If --stack-loc passes
        the begining of the stack area to aslink.

        * \sdcc\src\SDCCmem.c:  If a register bank is used, marks it so
        glue() in SDCCglue.c creates an area for it.

2002-09-03  Borut Razem <borut.razem AT siol.net>
        * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
        sdcc/src/pic/glue.c:
        introduced atexit() handler for teporay files removal in case of
        errors, assertions, ...

2002-08-29  Borut Razem <borut.razem AT siol.net>
        * sdcc/support/cpp2/auto-host_vc_in.h:
        re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
        with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
        Maybe there is a similar problem with BORLANDC? It should be checked!

        * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
        corrected improper use of assert: the assignment to clr variable was done inside the assert.
        In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
        was not executed, and the compiler (cl) launched a warning:
        ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized

2002-08-28  Bernhard Held <bernhard AT bernhardheld.de>
        * src/SDCCglue.c (printIvalArray): iterative calculation of array length

2002-08-28  Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
        * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

        * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
          sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

          sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
          sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
          sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
        - added Release configuration in VS projects
        - review of compiler an linker options
        - VC .exe files are generated in bin_vc directory, not to interfere
          with binaries generated from other projects (cygwin, mingw, bcc ...)

        * sdcc/src/yacc.dsp: added

        * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
        added - genarate sdcc_vc.h using sdcc_vc_in.h as template
        and insert the version number definitions from .version

        * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp

        * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
        added - genarate auto-host.h using auto-host_vc_in.h as template

        * sdcc/sdcc_vc.h,
        removed from CVS, generated automatically

2002-08-25  Bernhard Held <bernhard AT bernhardheld.de>
        * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)

2002-08-11  Borut Razem <borut.razem AT siol.net>
        * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)

2002-08-10  Borut Razem <borut.razem AT siol.net>
        * src/SDCCmain.c (main):
        file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
        platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
        The consequence was that some temporary files were not removed.

        * src/SDCCglue.c:
        unification of code in functions tempfilename() and tempfile():
        function tempnam() is defined in Visual Studio 6.0 and .NET

        * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a

        added newline in the def file to keep MSC compiler satisfied

        * sdcc/src/z80/gen.c:
        - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
          so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
        - solved MSC error in function aopDump()

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

2002-02-21    <johan AT FRIJA>

        * src/SDCCcse.c: fixed bug #514308
