260 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
263 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
265 * src/.version: increased version number to 2.5.5
266 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
267 linking is done manually in pic16 port's _linkEdit,
268 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
269 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

2642 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2644 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

2648 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2649 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2650 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2651 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2652 always available in leading double underscore form. The C99 support is
2653 mostly missing, but it's a start.
2654 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2655 reserved identifier "__data".
2657 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2659 * src/mcs51/peeph.def: fixed bug 1170013

2701 immedDom() returning wrong block; probably fixes bug #1160833)
2703 2005-03-20 Borut Razem <borut.razem AT siol.net>
2705 * support/scripts/inc2h.pl: WIN32 port

2711 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2713 * device/include/stdint.h: added
2714 * device/lib/abs.c: added

2733 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2735 * device/lib/printf_large.c: removed inline assembly for portability and
2736 readability. Use printf_fast if speed or size are more important.
2737 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2738 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2740 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2742 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2743 prevent compiler warning
2745 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2747 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2748 moved to level 0 and declared as static. Also they are explicit
2749 placed in access bank. This was necessery because some times they
2750 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2751 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2752 optimizations. Currently only compare to unsigned char is implemented,
2753 * src/pic16/gen.c: added fReturnIdx array,
2754 * (struct resolvedIfx) is moved to gen.h and made public,
2755 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2756 * (aopForSym): added an optimization to directly store in stack of
2757 the operand of a SEND iCode,
2758 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2759 but as registers instead (AOP_REG) using the fReturnIdx array,
2760 * (pic16_freeAsmop): remove the freed register from the
2761 _G.sregsAlloc field,
2762 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2763 a compare of 'WREG',
2764 * (pic16_popGetTempRegCond): changed function prototype, now
2765 function takes also a bitVector argument v which holds the current
2766 set of registers that are allocated for stack access by aopForSym,
2767 registers allocated in aopForSym for accessing stack symbols are not
2768 any more part of the functions usedRegs field,
2769 * (genCall): some times aopOp is called for a stack variable to be
2770 send, aopForSym might perform the push, if this is true make sure
2771 that genCall doesn't push the variable twice by testing _G.resDirect,
2772 * (genFunction): changed testing for unspecified interrupt number
2773 from 256 to INTNO_UNSPEC,
2774 * modified selection scheme of frame pointer generation. Previously
2775 if function did use local registers a frame pointer was generated,
2776 now a frame pointer is generated only if function has arguments
2777 (that need PLUSW2 register access), or has stack arguments, or the
2778 compiler is not instructed to omit the frame pointer,
2779 * (genEndFunction): before restoring local registers that were saved
2780 in the function preamble, also restore the registers that *might*
2781 have been allocated for stack access,
2782 * (genRet): removed some old comments,
2783 * (genCmp, the active (RN's) version): added a call to the
2784 pic16_genCmp_special function to perform the compare with a more
2785 robust and optimized way,
2786 * (genInline): a feature has been added in inline code generation,
2787 which allows a wildcard variable substitution when writing inline
2788 assembly. Code is incomplete and experimental therefore undocumented,
2789 * (genCast): changed order of aopOp for result and right to allow
2790 aopForSym to directly load the result if possible,
2791 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2792 perform an optimized compare on some selected special occasions,
2793 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2794 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2795 generate an IVT any more,
2796 * src/pic16/main.c (pic16_optionsTable): added command line option
2798 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2799 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2801 * src/pic16/NOTES: Raphael Neider added in list of active developers
2802 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2803 jumptable_end to prevent bug #,
2804 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2805 inCond and outCond fields,
2806 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2807 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2808 turn off register spilling,
2809 * (packRegsForOneUse): synced with other ports' versions although it
2810 is not used currently,
2811 * (pic16_packRegisters): added an optimization while reading
2812 structure bitfields, some registers may be saved (malloc code is
2813 decreased by 80 bytes)
2815 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2817 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2818 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2819 this can be optimized more?
2821 2005-03-10 Raphael Neider <rneider AT web.de>
2823 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2824 genNearPointerGet): (hopefully) fixed access to bitfields via
2825 pointers (p->bitN = x; and x = p->bitN; failed)
2827 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3004 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3005 (sizeof(sectNames) changed to sizeof(sectName))

3013 of (byte sized) temporaries (assign them to WREG for now)
3014 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3015 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3016 this might fix SIGSEGVs on MinGW...
3017 * src/SDCCopt.c (killDeadCode): restored original behaviour
3018 (volatile operands might get thrown away though)

3446 comparisons, and supports quoted literals
3447 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3449 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3457 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3459 Adding support for replacing ljmps with sjmps in jumptables
3460 generated for switch statements. For now you need to set the
3461 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3462 Now 4 algorithms for mcs51 jumptable generation are used:
3463 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3464 addresses loaded pc-relative for up to 112 cases and stack-pushing
3465 target addresses loaded with offset from dptr for up to 256 cases.
3467 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3468 * src/mcs51/main.c: adapted constants for switch table generation
3469 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3491 Large cummulative patch for pic16 port.
3492 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3493 to call when a stack overflow occurs,
3494 * (malloc.h): added CVS Id tag,
3495 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3497 * added libc directory. The current version of LibC contains string
3498 functions, ctype functions and macros and some functions of the
3499 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3500 be extensively tested in the future. Standard disclaimer here.
3501 Library is not automatically build yet. But one can build it by
3502 invoking 'make' inside the libc directory.
3503 * added ADC library under libio. Preliminary version yet.
3505 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3506 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3507 aopForRemat() now and not by pic16_aopOp(),
3508 * (pic16_popGetTempReg): removed warning messgae when allocating
3509 temporary registers, its a buggy feature and will be removed,
3510 * (pic16_popGet): set register instance field in AOP_CRY,
3511 * (pic16_outBitC): fixed for results in size greater than 1,
3512 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3513 * (pic16_storeForReturn): optimized return of 0,
3514 * (genCmp): experimental code for new genCmp which uses PIC18's
3515 special compare&skip instructions. Initial tests fail some times
3516 with variables grater than 1 byte in size, so new code is disabled,
3517 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3519 * (genCast): began a fix to optimize the casting of a bit to another
3520 bit, now assigning a bitfield to another bitfield will fail, sorry,
3521 * src/pic16/main.c: disabled the use of lr-support feature,
3522 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3523 * added some function prototypes, added function _debugf prototype,

3525 bits with offset (case PO_GPR_BIT),
3526 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3528 * (isBankInstruction): modified to return 0 for no banking instruction,
3529 and 1 for banking instruction,
3530 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3531 caused stop processing pCodes after a inline assembly block,
3532 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3533 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3534 registers when it shouldn't,
3535 * src/pic16/ralloc.c (allocReg): add preliminary support for
3536 supporting a limited set of temporary registers,
3538 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3540 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3541 genDataPointerSet): ensure assignments always copy in MSB to LSB
3543 (loadRegFromAop): recognize CLRH optimization,
3544 (genFunction): optimize RECEIVE iCodes in reentrant functions
3546 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3548 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6546 loaded with the linker search paths (-L arguments) and the libraries
6547 to be linked with the current source (-l arguments). Changes
6548 currently will affect only the pic16 port.
6549 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6550 include path the port specific paths and port specific libraries,
6551 * gplink command now contains the $3 argument,
6552 * src/pic16/device.h,
6553 * src/pic16/device.c,: structure PIC_device is made public and
6554 renamed to PIC16_device, the same for variable Pics which is renamed
6555 to Pics16. Updated all references to them.
6556 * src/pic16/glue.c (pic16glue): corrected bug with code
6557 initialization which bypassed the variable initializations block.
6559 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6560 COMPILE_FLAGS and added the --nostdinc option
6562 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6564 * device/include/mc68hc908jb8.h: Register defs for another member
6565 of the hc08 family. Contributed by Bjorn Bringert - thanks!
6567 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6569 Documenting changes from previous commits.
6570 * configure.in (version 1.56),
6571 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6572 when generating output files to configure the pic16 library,
6573 but now I've commented it out, since gputils aren't installed in the
6574 SF compile farm, so library won't compile
6576 * device/lib/Makefile.in (version 1.56): initially I've added in
6577 target 'all' the prerequestive 'model-pic16' so it compiled the
6578 pic16 library, but now I've commented it out for the same reasons
6580 * added targets 'model-pic16' and 'objects-pic16' to compile the
6582 * added target 'port-specific-objects-pic16' to handle the
6583 generated libraries and copy them into the build/ directory
6584 * added target 'clean-intermediate-pic16' to clean intermediate
6585 files into pic16 directory
6586 * in target 'installdirs' added line to create directory pic16 in
6587 the installation path
6589 * device/include/Makefile.in (version 1.11): in target 'install'
6590 added lines to copy all header files to installation path,
6591 * in target 'installdirs' added line create directory for pic16
6592 headers in the installation path
6594 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6607 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6608 option so that it actually works. Made it specific to the z80, since
6609 the gbz80 doesn't have these kinds of I/O ports.
6611 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6613 * device/include/z180.h,

6626 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6628 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6629 changed interrupt vector table generation to only emit declared vectors.

6635 Mainly changes to support compilation of the device libraries
6636 * src/pic16/device.c: stack is allocated via symbol and not
6637 via literal number. The symbol is placed in the corresponding
6638 position of the data ram
6639 * (pic16_dump_section): relocatable and absolute uninitialized
6640 data are now emitted in sorted order to reduce section naming,
6641 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6642 weren't marked as being in the access bank,
6644 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6646 Added portion of GNU PIC Library under the directory
6647 device/include/pic16 and device/lib/pic16. These files
6648 contain the declarations of SFRs for the PIC18Fxx2 devices.
6649 The directory is initialized via configure from toplevel.
6651 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6653 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6654 the spilllocations to be compared correctly
6656 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6658 * src/SDCCast.c (decorateType): fixed bug introduced today
6660 2004-01-12 Borut Razem <borut.razem AT siol.net>

6678 * doc/sdccman.lyx: Moved and added some sections, small changes
6679 all over. Telling LaTeX to be less strict with word spacing
6680 to better keep the right margin. Changed some notes about
6681 maintainance of the ports in section 3.2.1 - is it OK like this?
6683 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6720 UPPER for immediate operands,
6721 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6723 * src/pic16/peeph.def: all peepholes with movff are commented out,
6724 because there is a problem in the pcode peep optimizer,
6725 * src/pic16/ralloc.c: the register allocator can now reuse local

6727 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6729 Added file src/pic16/NOTES with information about program writing on
6730 the current port version.

6762 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6765 * src/z80/main.c: added missed needLinkerScript flags (more than
6766 one port structure defined in these file)
6767 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6783 needLinkerScript flag
6785 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6786 * src/pic/glue.c: added variable udata_section_name to
6787 override default uninitialized data segment definition for
6788 devices only with SHAREBANK memory (reported from Erik Epetrich)
6789 * (pic14emitOverlay): modified to emit a commented overlay segment
6790 directive when no overlay data exist
6791 * (picglue): modified to emit uninitialized data segment
6792 according to udata_section_name

6798 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6799 object file from '.rel' to '.o' in port->linker structure,
6800 changed size of fptr from 2 to 3 in port structure
6802 2004-01-07 Borut Razem <borut.razem AT siol.net>
6804 * support/scripts/sdcc.nsi: update PATH
6805 * support/scripts/sdcc.ico: craeted
6807 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6818 include information about variables allocated to the overlay
6821 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6823 * as/mcs51/lkmain.c: Help about -Y option

6835 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6837 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6838 (default behaviour).
6840 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6842 A python script to validate compiler diagnostic messages. It can be
6843 used to verify that sdcc complains about bad c source code and
6844 gives a good location of the error.
6845 * support/valdiag/Makefile,
6846 * support/valdiag/valdiag.py,
6847 * support/valdiag/tests/*
6849 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6862 * src/common.h: added ifndef/define/endif macros
6863 around the header file.
6864 Bug reported from Jesus Calvino-Fraga
6866 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6868 * sdcc.spec: updated
6869 * device/include/Makefile.in: don't install CVS directories
6870 * device/lib/Makefile.in: added removal of CVS directories after install
6871 * doc/Makefile: fixed install, added local_icons
6872 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6873 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6874 * src/ds390/gen.c (genRightShift): fixed bug #870788
6875 * src/SDCCast.c (decorateType): fixed bug #870781
6877 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6879 PIC16 port related changes:
6880 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6881 added variable stackPos,
6883 * gen.c: genCall, assignResultValue: added support for
6884 pushing/retrieving function parameters to/from stack,
6885 genFunction,genEndFunction: setup stack frame for the
6887 genAddrOf: will be changed according to bug 863624
6889 * added files genutils.c and genutils.h which contain gen*
6890 debugged and optimised functions extracted from gen.c
6892 * glue.c: added variable 'externs' which holds extern symbols,
6893 pic16emitRegularMap: is modified to properly handle relocatable
6894 symbols under the new scheme,
6895 pic16createInterruptVect: is modified
6896 pic16printPublics: is modified to emit 'global' assembler directives,
6897 added pic16_printExterns to print extern symbols,
6898 pic16glue: initializes stack/frame pointer in the beginning of
6899 the assembly output. Temporary hack, will be corrected later,
6900 because gplink yet does not support stack and SDCC does not
6901 yet support a type of crt0.o object to create the final binary.
6903 * Removed many lines that contain 8051 legacy code.
6904 * The code is finally placed under a 'code' directive.
6905 * Added port specific options.
6907 * _process_pragma: simplified since now we do not need *special*
6908 include file to define SFR registers. But a separate header
6909 will be needed. This will be developed later.
6910 * _pic16_parseOptions: added, parses port specific options:
6911 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6912 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6913 --preplace-udata-with=
6915 * _pic16_setDefaultOptions: modified to initialize section names,
6916 but hack is temporarly out of order since it needs improvement.
6917 * _pic16_genAssemblerPreamble: configuration words are emitted by
6918 their address instead of their name. This part is incomplete and
6919 supports only the 18Fxx2 devices. Other devices will emit an error
6920 during assembly since they do not contain the same set of config
6922 * _pic16_genIVT: is modified,
6924 * pcode.c: added definitions for some hardware registers that are needed
6926 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6927 All PCI entries are updated. Now LFSR is supported.
6928 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6929 * added pic16_newpCodeOpLit2 to support instructions with
6930 two literal arguments
6931 * pic16_pCode2str: corrected code that emits assembler instructions
6932 with two literal operands and those that have an access bit modifier
6933 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6934 this fixes a bug which caused some labels to be lost, when an
6935 assembler directive was added, i.e. banksel,
6936 * pic16_FixRegisterBanking: improved logic that causes the insertion
6938 * InlineFunction: functions that are called once, are not any more
6939 inlined. This can be a port option in the future,
6941 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6943 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6944 hold the corresponding uninitialized symbols,
6945 * pic16_allocProcessorRegister: registers have explicit marked the
6947 * pic16_allocInternalRegister: registers are explicit marked as
6949 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6950 processing list, so bit registers were lost,
6953 * ralloc.h: added field 'accessBank' and original symbol operand
6954 in register definition,
6955 * removed the field isMapped from register definition,
6957 ** Several functions have been removed from various sources:
6958 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6959 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6960 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6961 pic16_assignRelocatableRegisters
6963 ** others have been introduced:
6964 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6965 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6967 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6969 * support/scripts/inc2h.pl: changed definition of BIT_AT
6970 to emit 'sbit at' instead of 'bit at'. This was a request.
6972 PIC16 port related preliminary changes:
6973 * gen.c: prefixed function popRegFromString with
6974 pic16_ and all references to it corrected
6975 * pcode.c: all pic16_pc_* hardware registers prefixed
6976 with underscore (_),
6977 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6978 * ralloc.c: newReg(): when register is REG_SFR then
6979 set address to rIdx,
6980 pic16_allocProcessorRegister(): marks register wasUsed=0
6981 pic16_writeUsedRegs(): added a call to assign processor
6982 registers via pic16_assignFixedRegisters
6984 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6986 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6987 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6988 variables in unused register banks. Also the SSEG is placed
6989 wherever there is enough space for it, and IDATA can be anywhere
6990 in internal RAM. For now compile using -Wl-Y[stack_size].
6991 The mem file is different for this option as well, since it
6992 makes no sense of talking about DSEG lenght.
6994 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6996 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6997 in certain cases, e.g. when ROM assignment, patch provided
6998 from Albert den Haan.
7000 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8043 A few small changes that speed up the peephole optimizer.
8047 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8049 Try to make the peephole optimizer smarter by maintaining
8050 an association between the assembly source code and the
8051 iCodes that originated them. Put this information to use
8052 with a new peephole rule condition "notVolatile" so that
8053 the rules can be aggressive yet still safe.
8058 * src/mcs51/peeph.def
8060 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8064 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8065 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8066 if the left or right operand symbols have the accuse flag set.
8068 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8070 Changed the type of the result of the ! (NOT) operator to char;
8071 previously it returned the same type as the source. This allows
8072 us to eliminate all the genFloatNot functions (all of its target
8073 implementations were very buggy) since !float can use the same
8076 * src/SDCCicode.c (ast2iCode): ! returns char

8085 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8086 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8087 during interrupts. Ensure WSAVE is located at a shared bank address.
8088 2. Fixed page selection in some places
8089 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8090 the registers name strings.
8091 4. Fixed "signed / unsigned compare" compiler warnings.
8092 5. The PIC port manages its own allocation of the general purpose
8093 registers, but makes no attempt to reuse them. As a result when
8094 compiling it soon runs out of general purpose registers. Some
8095 additional code was added to the files pcode.c and device.c to walk
8096 through the function call tree and rename the registers so that they
8106 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8107 genPlus() & genMinus() when the result is the same as left or right

8113 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8115 Made bitfield a distinct type from bit so that bitfields
8116 convert as per ANSI C and bits retain their traditional
8117 boolean style behaviour. Implemented bitfield support in
8125 * src/ds390/gen.c: bit v bitfield split
8126 * src/z80/gen.c: New support for bitfields
8127 * support/regression/tests/bitfields.c: reenabled z80,
8130 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8132 Rules 246.x, 247.x relate to bitfields, the others speed up
8133 access to xdata mapped I/O devices.
8135 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8137 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8139 Cleaned up genPackBits and genUnpackBits and added two helper
8140 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8141 for literal assignments in genPackBits (thanks to Frieder for
8147 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8149 Fixed bug #748310 (pointer to function type mishandled when the
8150 function name is omitted). Also fixed a SIGSEGV when a function
8151 attribute (reentrant, etc) is used on a non-function or on a
8152 function but misplaced before the parameter list.
8154 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8156 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8179 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8181 Made the constant following the "interrupt" keyword optional. If
8182 omitted, the function will not automatically be given an entry
8183 in the interrupt vector table (similar to #pragma NOIV, but
8184 less syntacticly kludgy). The interrupt number is also now
8185 range checked. Also fixed a bug in the high order bit example

8206 unsigned, but are signed by default
8207 * src/SDCCval.c (constVal): rearranged
8208 * src/SDCCval.c (valMod): preliminary fix
8209 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8626 condition and ignore commands.
8628 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8630 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
8631 is in parts still quite out of date, I did changes as far as I felt makes sense
8632 for a non-native english speaker.
8633 Please feel free to add to the manual or to correct my changes.
8634 * doc/Makefile: undid touching the date of intermediate tex files.
8636 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8651 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8653 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
8654 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8655 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8656 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
8659 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8661 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8662 the regression tests I'm not brave enough to enable 245.b, 245.c
8663 * doc/sdccman.lyx: added latex preamble for hyperref package.
8664 Using pdflatex this will give you a hyperlinked pdf file with
8665 bookmarks. (prepend '%' before /usepackage if this breaks something)
8667 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8677 * src/SDCCglue.c (printIval): fixed bug #739934
8679 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
8681 Applied patch from bug 737905 (renamed yylineo to mylineno):
8688 * src/pic16/pcode.c: Cleaned warnings
8689 * src/pic16/pcodeflow.c: Cleaned warnings
8690 * src/pic16/pcoderegs.c: Cleaned warnings

8700 * doc/sdccman.lyx: fixed bug 739745
8701 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
8703 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8705 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8706 it can be defined with CFLAGS when running configure
8707 * src/SDCCmain.c: fixed compiling + linking with object files
8709 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8711 * configure.in: configure for pic16 port,
8712 added --disable-pic16-port
8713 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8714 * src/SDCCmain.c: linkOptions is changed to set *,
8715 added if/endif conditional macros to remove options help
8716 messages from optionsTable when a port is not configured, added
8717 support for the PIc16 port in the ports table, when executing
8718 the compiler with no port specified on command line, a default
8719 port is selected with the new macro DEFAULT_PORT which is
8720 defined in port.h, in setDefaultOptions() linkOptions is removed
8721 from initialization assignment, since now it is a set,
8722 parseCmdLine uses setParseWithComma for linkOptions, in
8723 linkEdit() linkOptions are accessed with new function indexSet()
8724 which returns the i'th item of a set variable. See SDCCset.c, in
8725 linkEdit() when calling buildCmdLine(), added linkOptions as
8726 last argument. Now users can pass arguments to gplink via the
8727 -Wl option, main() uses pic16glue() to glue up pic16 programs
8728 * src/SDCCpeeph.c: various changes to support pic16
8729 * src/SDCCset.c: added function void *indexSet(set *, int) to
8730 return the i'th item of the set

8733 * src/clean.mk: added pic16 in CLEANALLPORTS variable
8734 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
8735 added macro DEFAULT_PORT
8736 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
8737 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8739 * src/pic16/glue.c: commented out some error producing lines
8740 * src/pic16/main.c: __config directives are commented out to stop
8741 gpasm complaining and test the linkage with gplink, _linkCmd and
8742 _asmCmd changed to be more gplink and gpasm friendly
8743 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8744 produced an error when parsed, peep rule 12 is added to utilize
8745 movff, but it is commented out since the pCode does not support
8746 yet a command with 2 address arguments
8748 2003-05-18 <johan AT balder>
8750 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8751 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8770 on entry now. Add tbreak. Other enhancements and fixes for use
8773 2003-05-12 Borut Razem <borut.razem AT siol.net>
8775 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8777 2003-05-11 Borut Razem <borut.razem AT siol.net>
8779 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8780 the path of bin directory, so that PATH is the only env. variable, which has to be set
8781 in case of standard installation.
8782 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9811 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9813 * in \sdcc\as\mcs51\ changed these files in order to create an
9814 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9815 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9816 following files to include the previous two files: aslink.dsp,
9817 Makefile.aslink, Makefile.bcc, and Makefile.in.
9819 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9820 .adb instead of .cdb
9822 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9824 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9825 value from option --iram-size.
9827 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9829 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9832 2002-09-18 <wiml AT hhhh.org>
9834 * SDCClrange.h: exposed setFromRange() and setToRange()
9835 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9836 packRegsForAccUse() (bug 542397)
9837 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9838 multiple times and emitting the fetch operations more than once
9839 added aopGetUsesAcc() function to allow binary operators to
9840 fetch their operands in the correct order; made genMinus() emit
9841 compact code for X = LITERAL - Y
9843 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9844 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9845 sprintf() in line 1267.
9847 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9848 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9851 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9852 Changes to aslink (All the changes are marked with 'JCF'):
9854 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9857 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9858 area BSEG. Also moves, if possible, the DATA area down into the internal
9859 ram so more space is available.
9861 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9864 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9865 not bytes. Function summary() which creates a memory usage summary
9866 file with extension .mem. Reports of overlaping stack and small stack
9867 size. If the space for the stack is less than 16 bytes aslink trows a
9870 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9871 the 8051. Option 'y' for memory summary output file.
9873 Changes to sdcc (All the changes are marked with 'JCF'):
9875 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9877 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9878 overlaying area for it (uses RegBankUsed[4]).
9880 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9881 bank zero as used by default. By default aslink locates the stack
9882 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9883 the creation of the .mem file. Delegates the allocation of data area
9884 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9885 the begining of the stack area to aslink.
9887 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9888 glue() in SDCCglue.c creates an area for it.
9890 2002-09-03 Borut Razem <borut.razem AT siol.net>
9891 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9892 sdcc/src/pic/glue.c:
9893 introduced atexit() handler for teporay files removal in case of
9894 errors, assertions, ...
9896 2002-08-29 Borut Razem <borut.razem AT siol.net>
9897 * sdcc/support/cpp2/auto-host_vc_in.h:
9898 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9899 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9900 Maybe there is a similar problem with BORLANDC? It should be checked!
9902 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9903 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9904 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9905 was not executed, and the compiler (cl) launched a warning:
9906 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9908 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9926 * sdcc/src/yacc.dsp: added
9928 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9929 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9930 and insert the version number definitions from .version
9932 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9934 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9935 added - genarate auto-host.h using auto-host_vc_in.h as template
9938 removed from CVS, generated automatically
9940 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9941 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9943 2002-08-11 Borut Razem <borut.razem AT siol.net>
9944 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9946 2002-08-10 Borut Razem <borut.razem AT siol.net>
9947 * src/SDCCmain.c (main):
9948 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9949 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9950 The consequence was that some temporary files were not removed.
9953 unification of code in functions tempfilename() and tempfile():
9954 function tempnam() is defined in Visual Studio 6.0 and .NET
9956 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9958 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9959 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9960 - removed compiler command line option /WX: Treats all warnings as errors
9961 - update a list of source files, included into the project
9963 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9964 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9965 changed project type to Generic Project so that can be correcly converted to VS.NET project
9967 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9969 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9973 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9974 added return 0 statements after assert() to make compiler happy
9976 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9977 added newline in the def file to keep MSC compiler satisfied
9979 * sdcc/src/z80/gen.c:
9980 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9981 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9982 - solved MSC error in function aopDump()
9984 * sdcc_vc.h: define PREFIX as "\\sdcc"
9986 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9987 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10041 Compiler generated registers for interrupt context saving
10042 were not getting allocated.
10044 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

10159 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10161 * sdcc/src/SDCCloop.c:
10162 Previous fix was not good. basic blocks that have "break" or "return" are
10163 not really partof a loop , but live ranges used in these blocks should
10164 be live thru the entire loop, so set partOfLoop but don't add them to
