273 the left operand is shorter than the result (c* = lit-c* + int),
275 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
278 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
280 * src/.version: increased version number to 2.5.5
281 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
282 linking is done manually in pic16 port's _linkEdit,
283 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
284 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

300 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
301 call to allocReg, not by manually allocating a new one,
302 (pic16_assignRegisters): now before going through the register
303 allocating functions mark all registers as free. This eliminates some
304 side effects resulting from peephole parser done earlier in the backbone

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

2748 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2750 * device/lib/printf_large.c: removed inline assembly for portability and
2751 readability. Use printf_fast if speed or size are more important.
2752 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2753 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2755 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2757 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2758 prevent compiler warning
2760 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2762 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2763 moved to level 0 and declared as static. Also they are explicit
2764 placed in access bank. This was necessery because some times they
2765 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2766 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2767 optimizations. Currently only compare to unsigned char is implemented,
2768 * src/pic16/gen.c: added fReturnIdx array,
2769 * (struct resolvedIfx) is moved to gen.h and made public,
2770 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2771 * (aopForSym): added an optimization to directly store in stack of
2772 the operand of a SEND iCode,
2773 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2774 but as registers instead (AOP_REG) using the fReturnIdx array,
2775 * (pic16_freeAsmop): remove the freed register from the
2776 _G.sregsAlloc field,
2777 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2778 a compare of 'WREG',
2779 * (pic16_popGetTempRegCond): changed function prototype, now
2780 function takes also a bitVector argument v which holds the current
2781 set of registers that are allocated for stack access by aopForSym,
2782 registers allocated in aopForSym for accessing stack symbols are not
2783 any more part of the functions usedRegs field,
2784 * (genCall): some times aopOp is called for a stack variable to be
2785 send, aopForSym might perform the push, if this is true make sure
2786 that genCall doesn't push the variable twice by testing _G.resDirect,
2787 * (genFunction): changed testing for unspecified interrupt number
2788 from 256 to INTNO_UNSPEC,
2789 * modified selection scheme of frame pointer generation. Previously
2790 if function did use local registers a frame pointer was generated,
2791 now a frame pointer is generated only if function has arguments
2792 (that need PLUSW2 register access), or has stack arguments, or the
2793 compiler is not instructed to omit the frame pointer,
2794 * (genEndFunction): before restoring local registers that were saved
2795 in the function preamble, also restore the registers that *might*
2796 have been allocated for stack access,
2797 * (genRet): removed some old comments,
2798 * (genCmp, the active (RN's) version): added a call to the
2799 pic16_genCmp_special function to perform the compare with a more
2800 robust and optimized way,
2801 * (genInline): a feature has been added in inline code generation,
2802 which allows a wildcard variable substitution when writing inline
2803 assembly. Code is incomplete and experimental therefore undocumented,
2804 * (genCast): changed order of aopOp for result and right to allow
2805 aopForSym to directly load the result if possible,
2806 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2807 perform an optimized compare on some selected special occasions,
2808 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2809 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2810 generate an IVT any more,
2811 * src/pic16/main.c (pic16_optionsTable): added command line option
2813 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2814 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2816 * src/pic16/NOTES: Raphael Neider added in list of active developers
2817 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2818 jumptable_end to prevent bug #,
2819 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2820 inCond and outCond fields,
2821 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2822 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2823 turn off register spilling,
2824 * (packRegsForOneUse): synced with other ports' versions although it
2825 is not used currently,
2826 * (pic16_packRegisters): added an optimization while reading
2827 structure bitfields, some registers may be saved (malloc code is
2828 decreased by 80 bytes)
2830 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2832 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2833 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2834 this can be optimized more?
2836 2005-03-10 Raphael Neider <rneider AT web.de>
2838 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2839 genNearPointerGet): (hopefully) fixed access to bitfields via
2840 pointers (p->bitN = x; and x = p->bitN; failed)
2842 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3453 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3455 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
3457 (setFromConditionArgs): friendly operand parser for peephole rules,
3458 (operandBaseName, operandsNotRelated): new peephole condition
3459 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3460 architecture specific register naming into account, handles n-way
3461 comparisons, and supports quoted literals
3462 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

3472 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3474 Adding support for replacing ljmps with sjmps in jumptables
3475 generated for switch statements. For now you need to set the
3476 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3477 Now 4 algorithms for mcs51 jumptable generation are used:
3478 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3479 addresses loaded pc-relative for up to 112 cases and stack-pushing
3480 target addresses loaded with offset from dptr for up to 256 cases.
3482 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3483 * src/mcs51/main.c: adapted constants for switch table generation
3484 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3506 Large cummulative patch for pic16 port.
3507 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3508 to call when a stack overflow occurs,
3509 * (malloc.h): added CVS Id tag,
3510 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3512 * added libc directory. The current version of LibC contains string
3513 functions, ctype functions and macros and some functions of the
3514 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3515 be extensively tested in the future. Standard disclaimer here.
3516 Library is not automatically build yet. But one can build it by
3517 invoking 'make' inside the libc directory.
3518 * added ADC library under libio. Preliminary version yet.
3520 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3527 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3528 * (pic16_storeForReturn): optimized return of 0,
3529 * (genCmp): experimental code for new genCmp which uses PIC18's
3530 special compare&skip instructions. Initial tests fail some times
3531 with variables grater than 1 byte in size, so new code is disabled,
3532 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3534 * (genCast): began a fix to optimize the casting of a bit to another
3535 bit, now assigning a bitfield to another bitfield will fail, sorry,
3536 * src/pic16/main.c: disabled the use of lr-support feature,
3537 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3538 * added some function prototypes, added function _debugf prototype,

3540 bits with offset (case PO_GPR_BIT),
3541 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3543 * (isBankInstruction): modified to return 0 for no banking instruction,
3544 and 1 for banking instruction,
3545 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3546 caused stop processing pCodes after a inline assembly block,
3547 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3548 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3549 registers when it shouldn't,
3550 * src/pic16/ralloc.c (allocReg): add preliminary support for
3551 supporting a limited set of temporary registers,
3553 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3555 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3556 genDataPointerSet): ensure assignments always copy in MSB to LSB
3558 (loadRegFromAop): recognize CLRH optimization,
3559 (genFunction): optimize RECEIVE iCodes in reentrant functions
3561 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3563 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3564 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3566 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3575 instead of sjmp to ret
3576 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3577 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3579 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6551 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
6553 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
6555 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
6558 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6560 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6561 loaded with the linker search paths (-L arguments) and the libraries
6562 to be linked with the current source (-l arguments). Changes
6563 currently will affect only the pic16 port.
6564 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6565 include path the port specific paths and port specific libraries,
6566 * gplink command now contains the $3 argument,
6567 * src/pic16/device.h,
6568 * src/pic16/device.c,: structure PIC_device is made public and
6569 renamed to PIC16_device, the same for variable Pics which is renamed
6570 to Pics16. Updated all references to them.
6571 * src/pic16/glue.c (pic16glue): corrected bug with code
6572 initialization which bypassed the variable initializations block.
6574 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6575 COMPILE_FLAGS and added the --nostdinc option
6577 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6579 * device/include/mc68hc908jb8.h: Register defs for another member
6580 of the hc08 family. Contributed by Bjorn Bringert - thanks!
6582 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6584 Documenting changes from previous commits.
6585 * configure.in (version 1.56),
6586 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6587 when generating output files to configure the pic16 library,
6588 but now I've commented it out, since gputils aren't installed in the
6589 SF compile farm, so library won't compile
6591 * device/lib/Makefile.in (version 1.56): initially I've added in
6592 target 'all' the prerequestive 'model-pic16' so it compiled the
6593 pic16 library, but now I've commented it out for the same reasons
6595 * added targets 'model-pic16' and 'objects-pic16' to compile the
6597 * added target 'port-specific-objects-pic16' to handle the
6598 generated libraries and copy them into the build/ directory
6599 * added target 'clean-intermediate-pic16' to clean intermediate
6600 files into pic16 directory
6601 * in target 'installdirs' added line to create directory pic16 in
6602 the installation path
6604 * device/include/Makefile.in (version 1.11): in target 'install'
6605 added lines to copy all header files to installation path,
6606 * in target 'installdirs' added line create directory for pic16
6607 headers in the installation path
6609 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6622 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6623 option so that it actually works. Made it specific to the z80, since
6624 the gbz80 doesn't have these kinds of I/O ports.
6626 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6628 * device/include/z180.h,

6641 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6643 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6644 changed interrupt vector table generation to only emit declared vectors.
6645 * device/include/Makefile.in: added missing backslash
6646 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
6648 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6650 Mainly changes to support compilation of the device libraries
6651 * src/pic16/device.c: stack is allocated via symbol and not
6652 via literal number. The symbol is placed in the corresponding
6653 position of the data ram
6654 * (pic16_dump_section): relocatable and absolute uninitialized
6655 data are now emitted in sorted order to reduce section naming,
6656 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6657 weren't marked as being in the access bank,
6659 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6661 Added portion of GNU PIC Library under the directory
6662 device/include/pic16 and device/lib/pic16. These files
6663 contain the declarations of SFRs for the PIC18Fxx2 devices.
6664 The directory is initialized via configure from toplevel.
6666 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6668 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6669 the spilllocations to be compared correctly
6671 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6673 * src/SDCCast.c (decorateType): fixed bug introduced today
6675 2004-01-12 Borut Razem <borut.razem AT siol.net>
6677 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

6680 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6682 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6683 in simpler and even better code
6685 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
6687 * src/SDCCicode.c (operandOperation): fixed bug #874819

6691 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6693 * doc/sdccman.lyx: Moved and added some sections, small changes
6694 all over. Telling LaTeX to be less strict with word spacing
6695 to better keep the right margin. Changed some notes about
6696 maintainance of the ports in section 3.2.1 - is it OK like this?
6698 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6735 UPPER for immediate operands,
6736 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6738 * src/pic16/peeph.def: all peepholes with movff are commented out,
6739 because there is a problem in the pcode peep optimizer,
6740 * src/pic16/ralloc.c: the register allocator can now reuse local

6742 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6744 Added file src/pic16/NOTES with information about program writing on
6745 the current port version.

6777 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6780 * src/z80/main.c: added missed needLinkerScript flags (more than
6781 one port structure defined in these file)
6782 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6798 needLinkerScript flag
6800 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6801 * src/pic/glue.c: added variable udata_section_name to
6802 override default uninitialized data segment definition for

6804 * (pic14emitOverlay): modified to emit a commented overlay segment
6805 directive when no overlay data exist
6806 * (picglue): modified to emit uninitialized data segment
6807 according to udata_section_name

6817 2004-01-07 Borut Razem <borut.razem AT siol.net>
6819 * support/scripts/sdcc.nsi: update PATH
6820 * support/scripts/sdcc.ico: craeted
6822 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6833 include information about variables allocated to the overlay
6836 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6838 * as/mcs51/lkmain.c: Help about -Y option

6850 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6852 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6853 (default behaviour).
6855 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6857 A python script to validate compiler diagnostic messages. It can be
6858 used to verify that sdcc complains about bad c source code and
6859 gives a good location of the error.
6860 * support/valdiag/Makefile,
6861 * support/valdiag/valdiag.py,
6862 * support/valdiag/tests/*
6864 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6875 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6877 * src/common.h: added ifndef/define/endif macros
6878 around the header file.
6879 Bug reported from Jesus Calvino-Fraga
6881 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6883 * sdcc.spec: updated
6884 * device/include/Makefile.in: don't install CVS directories
6885 * device/lib/Makefile.in: added removal of CVS directories after install
6886 * doc/Makefile: fixed install, added local_icons
6887 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6888 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6889 * src/ds390/gen.c (genRightShift): fixed bug #870788
6890 * src/SDCCast.c (decorateType): fixed bug #870781
6892 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6894 PIC16 port related changes:
6895 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6896 added variable stackPos,
6898 * gen.c: genCall, assignResultValue: added support for
6899 pushing/retrieving function parameters to/from stack,
6900 genFunction,genEndFunction: setup stack frame for the
6902 genAddrOf: will be changed according to bug 863624
6904 * added files genutils.c and genutils.h which contain gen*
6905 debugged and optimised functions extracted from gen.c
6907 * glue.c: added variable 'externs' which holds extern symbols,
6908 pic16emitRegularMap: is modified to properly handle relocatable
6909 symbols under the new scheme,
6910 pic16createInterruptVect: is modified
6911 pic16printPublics: is modified to emit 'global' assembler directives,
6912 added pic16_printExterns to print extern symbols,
6913 pic16glue: initializes stack/frame pointer in the beginning of
6914 the assembly output. Temporary hack, will be corrected later,
6915 because gplink yet does not support stack and SDCC does not
6916 yet support a type of crt0.o object to create the final binary.
6918 * Removed many lines that contain 8051 legacy code.
6919 * The code is finally placed under a 'code' directive.
6920 * Added port specific options.
6922 * _process_pragma: simplified since now we do not need *special*
6923 include file to define SFR registers. But a separate header
6924 will be needed. This will be developed later.
6925 * _pic16_parseOptions: added, parses port specific options:
6926 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6927 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6928 --preplace-udata-with=
6930 * _pic16_setDefaultOptions: modified to initialize section names,
6931 but hack is temporarly out of order since it needs improvement.
6932 * _pic16_genAssemblerPreamble: configuration words are emitted by
6933 their address instead of their name. This part is incomplete and
6934 supports only the 18Fxx2 devices. Other devices will emit an error
6935 during assembly since they do not contain the same set of config
6937 * _pic16_genIVT: is modified,
6939 * pcode.c: added definitions for some hardware registers that are needed
6941 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6942 All PCI entries are updated. Now LFSR is supported.
6943 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6944 * added pic16_newpCodeOpLit2 to support instructions with
6945 two literal arguments
6946 * pic16_pCode2str: corrected code that emits assembler instructions
6947 with two literal operands and those that have an access bit modifier
6948 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6949 this fixes a bug which caused some labels to be lost, when an
6950 assembler directive was added, i.e. banksel,
6951 * pic16_FixRegisterBanking: improved logic that causes the insertion
6953 * InlineFunction: functions that are called once, are not any more
6954 inlined. This can be a port option in the future,
6956 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6958 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6959 hold the corresponding uninitialized symbols,
6960 * pic16_allocProcessorRegister: registers have explicit marked the
6962 * pic16_allocInternalRegister: registers are explicit marked as
6964 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6965 processing list, so bit registers were lost,
6968 * ralloc.h: added field 'accessBank' and original symbol operand
6969 in register definition,
6970 * removed the field isMapped from register definition,
6972 ** Several functions have been removed from various sources:
6973 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6974 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6975 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6976 pic16_assignRelocatableRegisters
6978 ** others have been introduced:
6979 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6980 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6982 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6984 * support/scripts/inc2h.pl: changed definition of BIT_AT
6985 to emit 'sbit at' instead of 'bit at'. This was a request.
6987 PIC16 port related preliminary changes:
6988 * gen.c: prefixed function popRegFromString with
6989 pic16_ and all references to it corrected
6990 * pcode.c: all pic16_pc_* hardware registers prefixed
6991 with underscore (_),
6992 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6993 * ralloc.c: newReg(): when register is REG_SFR then
6994 set address to rIdx,
6995 pic16_allocProcessorRegister(): marks register wasUsed=0
6996 pic16_writeUsedRegs(): added a call to assign processor
6997 registers via pic16_assignFixedRegisters
6999 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7001 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7002 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7003 variables in unused register banks. Also the SSEG is placed
7004 wherever there is enough space for it, and IDATA can be anywhere
7005 in internal RAM. For now compile using -Wl-Y[stack_size].
7006 The mem file is different for this option as well, since it
7007 makes no sense of talking about DSEG lenght.
7009 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7011 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7012 in certain cases, e.g. when ROM assignment, patch provided
7013 from Albert den Haan.
7015 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8034 these ports have their own __sdcc_external_start()
8036 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8038 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8039 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8040 type for bits was changed. It resulted in bit variables becoming
8041 global, which is not permitted in PIC 14 assembly output.
8043 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8045 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8058 A few small changes that speed up the peephole optimizer.
8062 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8064 Try to make the peephole optimizer smarter by maintaining
8065 an association between the assembly source code and the
8066 iCodes that originated them. Put this information to use
8067 with a new peephole rule condition "notVolatile" so that
8068 the rules can be aggressive yet still safe.
8073 * src/mcs51/peeph.def
8075 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8079 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8080 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8081 if the left or right operand symbols have the accuse flag set.
8083 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8085 Changed the type of the result of the ! (NOT) operator to char;
8086 previously it returned the same type as the source. This allows
8087 us to eliminate all the genFloatNot functions (all of its target
8088 implementations were very buggy) since !float can use the same
8091 * src/SDCCicode.c (ast2iCode): ! returns char

8100 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8101 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8102 during interrupts. Ensure WSAVE is located at a shared bank address.
8103 2. Fixed page selection in some places
8104 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8105 the registers name strings.
8106 4. Fixed "signed / unsigned compare" compiler warnings.
8107 5. The PIC port manages its own allocation of the general purpose
8108 registers, but makes no attempt to reuse them. As a result when
8109 compiling it soon runs out of general purpose registers. Some
8110 additional code was added to the files pcode.c and device.c to walk
8111 through the function call tree and rename the registers so that they
8121 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8122 genPlus() & genMinus() when the result is the same as left or right

8128 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8130 Made bitfield a distinct type from bit so that bitfields
8131 convert as per ANSI C and bits retain their traditional
8132 boolean style behaviour. Implemented bitfield support in
8140 * src/ds390/gen.c: bit v bitfield split
8141 * src/z80/gen.c: New support for bitfields
8142 * support/regression/tests/bitfields.c: reenabled z80,
8145 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8147 Rules 246.x, 247.x relate to bitfields, the others speed up
8148 access to xdata mapped I/O devices.
8150 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8152 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8154 Cleaned up genPackBits and genUnpackBits and added two helper
8155 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8156 for literal assignments in genPackBits (thanks to Frieder for
8162 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8164 Fixed bug #748310 (pointer to function type mishandled when the
8165 function name is omitted). Also fixed a SIGSEGV when a function
8166 attribute (reentrant, etc) is used on a non-function or on a
8167 function but misplaced before the parameter list.
8169 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8171 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8194 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8196 Made the constant following the "interrupt" keyword optional. If
8197 omitted, the function will not automatically be given an entry
8198 in the interrupt vector table (similar to #pragma NOIV, but
8199 less syntacticly kludgy). The interrupt number is also now
8200 range checked. Also fixed a bug in the high order bit example

8214 * src/SDCCicode.c (operandOperation): rewritten some ops
8215 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8216 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8218 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8219 be re-activated by defining REDUCE_LITERALS)
8220 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8221 unsigned, but are signed by default
8222 * src/SDCCval.c (constVal): rearranged
8223 * src/SDCCval.c (valMod): preliminary fix
8224 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8647 for a non-native english speaker.
8648 Please feel free to add to the manual or to correct my changes.

8669 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8670 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8671 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

8676 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8677 the regression tests I'm not brave enough to enable 245.b, 245.c
8678 * doc/sdccman.lyx: added latex preamble for hyperref package.
8679 Using pdflatex this will give you a hyperlinked pdf file with
8680 bookmarks. (prepend '%' before /usepackage if this breaks something)

8696 Applied patch from bug 737905 (renamed yylineo to mylineno):
8703 * src/pic16/pcode.c: Cleaned warnings
8704 * src/pic16/pcodeflow.c: Cleaned warnings
8705 * src/pic16/pcoderegs.c: Cleaned warnings

8718 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8720 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8721 it can be defined with CFLAGS when running configure
8722 * src/SDCCmain.c: fixed compiling + linking with object files
8724 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8726 * configure.in: configure for pic16 port,
8727 added --disable-pic16-port
8728 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8729 * src/SDCCmain.c: linkOptions is changed to set *,
8730 added if/endif conditional macros to remove options help
8731 messages from optionsTable when a port is not configured, added
8732 support for the PIc16 port in the ports table, when executing
8733 the compiler with no port specified on command line, a default
8734 port is selected with the new macro DEFAULT_PORT which is
8735 defined in port.h, in setDefaultOptions() linkOptions is removed
8736 from initialization assignment, since now it is a set,
8737 parseCmdLine uses setParseWithComma for linkOptions, in
8738 linkEdit() linkOptions are accessed with new function indexSet()
8739 which returns the i'th item of a set variable. See SDCCset.c, in
8740 linkEdit() when calling buildCmdLine(), added linkOptions as
8741 last argument. Now users can pass arguments to gplink via the
8742 -Wl option, main() uses pic16glue() to glue up pic16 programs
8743 * src/SDCCpeeph.c: various changes to support pic16

8752 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8754 * src/pic16/glue.c: commented out some error producing lines
8755 * src/pic16/main.c: __config directives are commented out to stop
8756 gpasm complaining and test the linkage with gplink, _linkCmd and
8757 _asmCmd changed to be more gplink and gpasm friendly
8758 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8759 produced an error when parsed, peep rule 12 is added to utilize
8760 movff, but it is commented out since the pCode does not support
8761 yet a command with 2 address arguments
8763 2003-05-18 <johan AT balder>
8765 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8766 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8785 on entry now. Add tbreak. Other enhancements and fixes for use
8788 2003-05-12 Borut Razem <borut.razem AT siol.net>
8790 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8792 2003-05-11 Borut Razem <borut.razem AT siol.net>
8794 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8795 the path of bin directory, so that PATH is the only env. variable, which has to be set
8796 in case of standard installation.
8797 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9826 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9828 * in \sdcc\as\mcs51\ changed these files in order to create an
9829 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9830 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9831 following files to include the previous two files: aslink.dsp,
9832 Makefile.aslink, Makefile.bcc, and Makefile.in.
9834 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9835 .adb instead of .cdb
9837 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9839 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9840 value from option --iram-size.
9842 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9844 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9847 2002-09-18 <wiml AT hhhh.org>
9849 * SDCClrange.h: exposed setFromRange() and setToRange()
9850 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9851 packRegsForAccUse() (bug 542397)
9852 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9853 multiple times and emitting the fetch operations more than once
9854 added aopGetUsesAcc() function to allow binary operators to
9855 fetch their operands in the correct order; made genMinus() emit
9856 compact code for X = LITERAL - Y
9858 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9859 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9860 sprintf() in line 1267.
9862 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9863 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9866 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9867 Changes to aslink (All the changes are marked with 'JCF'):
9869 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9872 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9873 area BSEG. Also moves, if possible, the DATA area down into the internal
9874 ram so more space is available.
9876 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9879 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9880 not bytes. Function summary() which creates a memory usage summary
9881 file with extension .mem. Reports of overlaping stack and small stack
9882 size. If the space for the stack is less than 16 bytes aslink trows a
9885 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9886 the 8051. Option 'y' for memory summary output file.
9888 Changes to sdcc (All the changes are marked with 'JCF'):
9890 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9892 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9893 overlaying area for it (uses RegBankUsed[4]).
9895 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9896 bank zero as used by default. By default aslink locates the stack
9897 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9898 the creation of the .mem file. Delegates the allocation of data area
9899 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9900 the begining of the stack area to aslink.
9902 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9903 glue() in SDCCglue.c creates an area for it.
9905 2002-09-03 Borut Razem <borut.razem AT siol.net>
9906 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9907 sdcc/src/pic/glue.c:
9908 introduced atexit() handler for teporay files removal in case of
9909 errors, assertions, ...
9911 2002-08-29 Borut Razem <borut.razem AT siol.net>
9912 * sdcc/support/cpp2/auto-host_vc_in.h:
9913 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9914 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9915 Maybe there is a similar problem with BORLANDC? It should be checked!
9917 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9918 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9919 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9920 was not executed, and the compiler (cl) launched a warning:
9921 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9923 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9936 - added Release configuration in VS projects
9937 - review of compiler an linker options
9938 - VC .exe files are generated in bin_vc directory, not to interfere
9939 with binaries generated from other projects (cygwin, mingw, bcc ...)
9941 * sdcc/src/yacc.dsp: added
9943 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9944 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9945 and insert the version number definitions from .version
9947 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9949 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9956 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9958 2002-08-11 Borut Razem <borut.razem AT siol.net>
9959 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9961 2002-08-10 Borut Razem <borut.razem AT siol.net>
9962 * src/SDCCmain.c (main):
9963 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9964 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9965 The consequence was that some temporary files were not removed.
9968 unification of code in functions tempfilename() and tempfile():
9969 function tempnam() is defined in Visual Studio 6.0 and .NET
9971 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9973 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9974 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9975 - removed compiler command line option /WX: Treats all warnings as errors
9976 - update a list of source files, included into the project
9978 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9979 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9980 changed project type to Generic Project so that can be correcly converted to VS.NET project
9982 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9984 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9988 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9989 added return 0 statements after assert() to make compiler happy
9991 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9992 added newline in the def file to keep MSC compiler satisfied
9994 * sdcc/src/z80/gen.c:
9995 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9996 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9997 - solved MSC error in function aopDump()
9999 * sdcc_vc.h: define PREFIX as "\\sdcc"

10174 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10176 * sdcc/src/SDCCloop.c:
10177 Previous fix was not good. basic blocks that have "break" or "return" are
10178 not really partof a loop , but live ranges used in these blocks should
