2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>

        Enabled VPATH feature: changed nearly all Makefiles (149 files).
        See sdccman.lyx '2.4.10 VPATH feature' about how to use it.

        One basic decision: e.g. src/clean.mk includes further files. In order
        to make this work there are two solutions:
        - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
          run configure on them. This way they can use
          'include $(srcdir)/port-clean.mk'
        - always include clean.mk by the Makefile at the same level. To avoid
          that `make clean` tries to include and build Makefile.dep the
          MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
          implemented, because now even `make uninstall` doesn't create
          Makefile.in. clean.mk could be eliminated by pasting it in
          Makefile.in.

        * debugger/mcs51/Makefile.in: build own objects from library sources
        (SLIB, SDCC) in current directory

        * configure, configure.in: renamed --disable-device-lib-build in
        --disable-device-lib; added --enable-doc, the required tools are
        searched by configure; added result message; the toolchain for the
        belonging ports are now only built, if the port is enabled.

        * support/regression/*: all output is written in directory gen, because
        the fwk and ports directories don't livet in the build tree using vpath

        * doc/sdccman.lyx: renamed --disable-device-lib-build to
        --disable-device-lib, added --enable-doc, added section VPATH

        * sim/ucsim/configure.in,
        * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
        z80 are enabled by default

2006-04-24 Raphael Neider <rneider AT web.de>

        * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
            to config word, "pic14_"-prefixed some extern functions
          (pic14_emitConfigWord): emit __config directive(s) if assignment to
            config word has been found
        * src/pic/device.h: added prototypes
        * src/pic/pcode.c: added "pic14_"-prefix where needed
        * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
            fixup
        * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
            words,
          (pic14emitRegularMap): ignore config words,
          (pic14createInterruptVect): moved generating __config directives away
          (picglue): have __config directives emitted

2006-04-24 Borut Razem <borut.razem AT siol.net>

        * doc/Makefile: sync with nightly build makefile

2006-04-24 Raphael Neider <rneider AT web.de>

        * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
            registers that have not been assigned proper liveranges,
            fixes #1469504 and #1474602,
          (pCodeRegOptimizeRegUsage): fixed typo in comment

          after the transition to Subversion
        * src/SDCCalloc.h: deleted - it was removed  from CVS
          3.feb.2001 and after that modified 18.feb.2001, so it reappered

        * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
          OP_SYMBOL

2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>

        * src/.version: increased version number to 2.5.5
        * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
        linking is done manually in pic16 port's _linkEdit,
        * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
        PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
        * src/pic16/gen.c (aopForSym): when direct register name is WREG then
        allocate asmop as AOP_ACC,
        (aopForRemat): added parameter 'bool result' in function declaration,
        (pic16_aopGet): return AOP_ACC when accessing WREG,
        (pic16_popGetTempReg): minor modification,
        (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
        'pic16_allocWithIdx',
        (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
        calling function in absolute addresses,
        (genAssign): take into account AOP_ACC asmop,
        * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
        * src/pic16/pcoderegs.c: some debug functions and lines added,
        * src/pic16/ralloc.c (decodeRegType): added but commented out,
        * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
        register too,
        * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
        call to allocReg, not by manually allocating a new one,
        (pic16_assignRegisters): now before going through the register
        allocating functions mark all registers as free. This eliminates some
        side effects resulting from peephole parser done earlier in the backbone

2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

        * src/SDCCicode.c (geniCodeLogic),
        * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

          using asmop.freed,
          (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
          (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
           genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

            in reverse order from allocation,
          (genPlus, genCmpEq): free asmop's in reverse order from allocation and
            added swappedLR to keep track
        * support/regression/fwk/include/testfwk.h: added defines for xdata, idata,
          pdata & code for GCC, z80, gbz80 & hc08
        * support/regression/tests/zeropad.c: moved defines to testfwk.h

2006-03-08 Raphael Neider <rneider AT web.de>

2006-03-06 Borut Razem <borut.razem AT siol.net>

        * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
          made the linker quiet

2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

        * src/pic16/gen.c (genPcall): fixed bug #1443644
        * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
        which dumps before the function entry point a data byte which represents
        the number of the local variables used by the specified function, added
        'xinst' for initial support for Extended Instruction Support,
        * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
        (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
        port->fun_prefix anymore (may change later),
        (genFunction, genEndFunction): do not store/restore local registers for
        _main (this should take care the --main-return command line option in
        the future),
        (genOr): removed some legacy pic-port instructions,
        * src/pic16/genarith.c (genAddLit): re-enabled old code because
        performing operations with SFR's causes data to be written more than
        once to each SFR. Perhaps SFRs should be handled in special cases...
        * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
        pcode.h
        * src/pic16/main.c (_process_pragma): stack bound checking did not take
        into account for stack starting position,
        (struct OPTIONS pic16_optionsTable): added command line argument
        --extended or -y for Extended Instruction Support,
        * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
        (deassignLRs): *** perhaps the most important change, old 'for' code
        (commented out for reference), didn't account for some registers which
        were left marked 'not free' after a pointer operation. The change
        reduces register usage a lot in some cases

        * src/pic16/gen.c: removed conditions around use of DEBUGpc
        * src/pic16/genutils.h: added define for DEBUGpc for MSVC

2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>

        * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
        prevent compiler warning

2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>

        * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
        moved to level 0 and declared as static. Also they are explicit
        placed in access bank. This was necessery because some times they
        might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
        * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
        optimizations. Currently only compare to unsigned char is implemented,
        * src/pic16/gen.c: added fReturnIdx array,
        * (struct resolvedIfx) is moved to gen.h and made public,
        * (struct _G): added sregsAlloc and sregsAllocSet fields,
        * (aopForSym): added an optimization to directly store in stack of
        the operand of a SEND iCode,
        * (pic16_aopOp): don't return return registers as strings (AOP_STR)
        but as registers instead (AOP_REG) using the fReturnIdx array,
        * (pic16_freeAsmop): remove the freed register from the
        _G.sregsAlloc field,
        * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
        a compare of 'WREG',
        * (pic16_popGetTempRegCond): changed function prototype, now
        function takes also a bitVector argument v which holds the current
        set of registers that are allocated for stack access by aopForSym,
        registers allocated in aopForSym for accessing stack symbols are not
        any more part of the functions usedRegs field,
        * (genCall): some times aopOp is called for a stack variable to be
        send, aopForSym might perform the push, if this is true make sure
        that genCall doesn't push the variable twice by testing _G.resDirect,
        * (genFunction): changed testing for unspecified interrupt number
        from 256 to INTNO_UNSPEC,
        * modified selection scheme of frame pointer generation. Previously
        if function did use local registers a frame pointer was generated,
        now a frame pointer is generated only if function has arguments
        (that need PLUSW2 register access), or has stack arguments, or the
        compiler is not instructed to omit the frame pointer,
        * (genEndFunction): before restoring local registers that were saved
        in the function preamble, also restore the registers that *might*
        have been allocated for stack access,
        * (genRet): removed some old comments,
        * (genCmp, the active (RN's) version): added a call to the
        pic16_genCmp_special function to perform the compare with a more
        robust and optimized way,
        * (genInline): a feature has been added in inline code generation,
        which allows a wildcard variable substitution when writing inline
        assembly. Code is incomplete and experimental therefore undocumented,
        * (genCast): changed order of aopOp for result and right to allow
        aopForSym to directly load the result if possible,
        * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
        perform an optimized compare on some selected special occasions,
        * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
        * src/pic16/glue.c (pic16createInterrupVect): make sure we never
        generate an IVT any more,
        * src/pic16/main.c (pic16_optionsTable): added command line option
        --optimize-cmp,
        * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
        macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
        macros,
        * src/pic16/NOTES: Raphael Neider added in list of active developers
        * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
        jumptable_end to prevent bug #,
        * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
        inCond and outCond fields,
        * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
        * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
        turn off register spilling,
        * (packRegsForOneUse): synced with other ports' versions although it
        is not used currently,
        * (pic16_packRegisters): added an optimization while reading
        structure bitfields, some registers may be saved (malloc code is
        decreased by 80 bytes)

2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>

        * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
        left is a bitfield, if yes, then don't optimize assignment. Perhaps
        this can be optimized more?

2005-03-10 Raphael Neider <rneider AT web.de>

        * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
          genNearPointerGet): (hopefully) fixed access to bitfields via
          pointers (p->bitN = x; and x = p->bitN; failed)

2005-03-09 Paul Stoffregen <paul AT pjrc.com>

        * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2005-01-26 Raphael Neider <rneider AT web.de>

        * src/pic16/gen.c (genAssign): fixed assignment from longs
          in codespace (were cut to three bytes)
        * (genDummyRead): implemented (except for CODESPACE...),
          fixed bug #1108575
        * src/pic16/glue.c (emitStatistics): beautified
        * device/lib/pic16/libm/Makefile: added include path

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',
        * doc/sdccman.lyx: updated to reflect recent changes of pic16 port

2005-01-22 Vangelis Rokas <vrokas AT otenet.gr>

        * .version: bumped version number to 2.4.8

        * device/include/pic16/i2c.h: I2C support library header,
        * device/lib/pic16/libc/stdio/: standard IO support sources,
        * (printf_small.c): printf_small() source, supports float print,
        * (printf_tiny.c): printf_tiny() source, does not support floats,
        * device/lib/pic16/Makefile.common.in: added OPT_FLAGS macro to
        enable global optimizations for entire library source, other
        Makefiles in the source tree are also modified to reflect this,
        * device/lib/pic16/libc/stdlib/putchar.c (putchar): dummy putchar()
        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}
        when calling assembler to reflect memory model used, also define
        macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
        reflect stack model used,
        * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated
        on stack return NULL,

2005-01-22 Daniel Winkler <post AT danielwinkler.de>

        * src/SDCCopt.c (killDeadCode): do not throw iCodes away if one
          of the operands is volatile. Fixes #1020220

2005-01-22 Daniel Winkler <post AT danielwinkler.de>

        * src/pic16/pcoderegs.c (pCodeOptime2pCodes): reenabled optimization
        * (OptimizeRegUsage): make sure that there is really no other flow where
          the first pCode is used

2005-01-22 Raphael Neider <rneider AT web.de>

        * src/pic16/pcoderegs.c (pCodeOptime2pCodes): disabled optimization
          to fix #1106967 (pCode->seq are not set up correctly)

2005-01-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

        * src/SDCCglue.c (glue): make sure code area is declared before the
        static initialization area.

2005-01-21 Raphael Neider <rneider AT web.de>

          added --optimize-goto compiler switch and pragma wparam documentation
        * src/pic16/pcode.c (pic16_OptimizeBanksel): removed statistics dump
        * src/pic16/pcodepeep.c (pic16_pCodeOpCopy): fixed copying of WREG, PRODL
          and PRODH closing bug #1071770 (peephole optimizer)

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)
        * (pic16_genMinusDec): performance improvements, removed false
          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
