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

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

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

2646 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2648 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

2652 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2653 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2654 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2655 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2656 always available in leading double underscore form. The C99 support is
2657 mostly missing, but it's a start.
2658 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2659 reserved identifier "__data".
2661 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2705 immedDom() returning wrong block; probably fixes bug #1160833)
2707 2005-03-20 Borut Razem <borut.razem AT siol.net>
2709 * support/scripts/inc2h.pl: WIN32 port

2737 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2739 * device/lib/printf_large.c: removed inline assembly for portability and
2740 readability. Use printf_fast if speed or size are more important.
2741 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2742 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2744 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2746 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2747 prevent compiler warning
2749 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2751 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2752 moved to level 0 and declared as static. Also they are explicit
2753 placed in access bank. This was necessery because some times they
2754 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2755 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2756 optimizations. Currently only compare to unsigned char is implemented,
2757 * src/pic16/gen.c: added fReturnIdx array,
2758 * (struct resolvedIfx) is moved to gen.h and made public,
2759 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2760 * (aopForSym): added an optimization to directly store in stack of
2761 the operand of a SEND iCode,
2762 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2763 but as registers instead (AOP_REG) using the fReturnIdx array,
2764 * (pic16_freeAsmop): remove the freed register from the
2765 _G.sregsAlloc field,
2766 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2767 a compare of 'WREG',
2768 * (pic16_popGetTempRegCond): changed function prototype, now
2769 function takes also a bitVector argument v which holds the current
2770 set of registers that are allocated for stack access by aopForSym,
2771 registers allocated in aopForSym for accessing stack symbols are not
2772 any more part of the functions usedRegs field,
2773 * (genCall): some times aopOp is called for a stack variable to be
2774 send, aopForSym might perform the push, if this is true make sure
2775 that genCall doesn't push the variable twice by testing _G.resDirect,
2776 * (genFunction): changed testing for unspecified interrupt number
2777 from 256 to INTNO_UNSPEC,
2778 * modified selection scheme of frame pointer generation. Previously
2779 if function did use local registers a frame pointer was generated,
2780 now a frame pointer is generated only if function has arguments
2781 (that need PLUSW2 register access), or has stack arguments, or the
2782 compiler is not instructed to omit the frame pointer,
2783 * (genEndFunction): before restoring local registers that were saved
2784 in the function preamble, also restore the registers that *might*
2785 have been allocated for stack access,
2786 * (genRet): removed some old comments,
2787 * (genCmp, the active (RN's) version): added a call to the
2788 pic16_genCmp_special function to perform the compare with a more
2789 robust and optimized way,
2790 * (genInline): a feature has been added in inline code generation,
2791 which allows a wildcard variable substitution when writing inline
2792 assembly. Code is incomplete and experimental therefore undocumented,
2793 * (genCast): changed order of aopOp for result and right to allow
2794 aopForSym to directly load the result if possible,
2795 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2796 perform an optimized compare on some selected special occasions,
2797 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2798 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2799 generate an IVT any more,
2800 * src/pic16/main.c (pic16_optionsTable): added command line option
2802 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2803 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2805 * src/pic16/NOTES: Raphael Neider added in list of active developers
2806 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2807 jumptable_end to prevent bug #,
2808 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2809 inCond and outCond fields,
2810 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2811 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2812 turn off register spilling,
2813 * (packRegsForOneUse): synced with other ports' versions although it
2814 is not used currently,
2815 * (pic16_packRegisters): added an optimization while reading
2816 structure bitfields, some registers may be saved (malloc code is
2817 decreased by 80 bytes)
2819 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2821 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2822 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2823 this can be optimized more?
2825 2005-03-10 Raphael Neider <rneider AT web.de>
2827 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2828 genNearPointerGet): (hopefully) fixed access to bitfields via
2829 pointers (p->bitN = x; and x = p->bitN; failed)
2831 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2874 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2875 to keep the correct label reference count when adding/removing references
2876 to labels. A peephole file using this is appended to patch #1144962.

3008 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3009 (sizeof(sectNames) changed to sizeof(sectName))
3010 Both patches fix segfaults under MinGW.
3012 2005-01-23 Raphael Neider <rneider AT web.de>

3016 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3017 of (byte sized) temporaries (assign them to WREG for now)
3018 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3019 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3020 this might fix SIGSEGVs on MinGW...

3448 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3449 architecture specific register naming into account, handles n-way
3450 comparisons, and supports quoted literals
3451 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3453 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3461 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3463 Adding support for replacing ljmps with sjmps in jumptables
3464 generated for switch statements. For now you need to set the
3465 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3466 Now 4 algorithms for mcs51 jumptable generation are used:
3467 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3468 addresses loaded pc-relative for up to 112 cases and stack-pushing
3469 target addresses loaded with offset from dptr for up to 256 cases.
3471 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3472 * src/mcs51/main.c: adapted constants for switch table generation
3473 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3495 Large cummulative patch for pic16 port.
3496 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3497 to call when a stack overflow occurs,
3498 * (malloc.h): added CVS Id tag,
3499 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3501 * added libc directory. The current version of LibC contains string
3502 functions, ctype functions and macros and some functions of the
3503 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3504 be extensively tested in the future. Standard disclaimer here.
3505 Library is not automatically build yet. But one can build it by
3506 invoking 'make' inside the libc directory.
3507 * added ADC library under libio. Preliminary version yet.
3509 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3516 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3517 * (pic16_storeForReturn): optimized return of 0,
3518 * (genCmp): experimental code for new genCmp which uses PIC18's
3519 special compare&skip instructions. Initial tests fail some times
3520 with variables grater than 1 byte in size, so new code is disabled,
3521 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3523 * (genCast): began a fix to optimize the casting of a bit to another
3524 bit, now assigning a bitfield to another bitfield will fail, sorry,
3525 * src/pic16/main.c: disabled the use of lr-support feature,
3526 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3527 * added some function prototypes, added function _debugf prototype,
3528 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3529 bits with offset (case PO_GPR_BIT),
3530 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3532 * (isBankInstruction): modified to return 0 for no banking instruction,
3533 and 1 for banking instruction,
3534 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3535 caused stop processing pCodes after a inline assembly block,
3536 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3537 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3538 registers when it shouldn't,
3539 * src/pic16/ralloc.c (allocReg): add preliminary support for
3540 supporting a limited set of temporary registers,
3542 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3544 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3545 genDataPointerSet): ensure assignments always copy in MSB to LSB
3547 (loadRegFromAop): recognize CLRH optimization,
3548 (genFunction): optimize RECEIVE iCodes in reentrant functions
3550 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3552 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3553 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3555 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3562 * device/lib/_gptrgetc.c (_gptrgetc),
3563 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
3564 instead of sjmp to ret
3565 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3566 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3568 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6551 to be linked with the current source (-l arguments). Changes
6552 currently will affect only the pic16 port.
6553 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6554 include path the port specific paths and port specific libraries,
6555 * gplink command now contains the $3 argument,
6556 * src/pic16/device.h,
6557 * src/pic16/device.c,: structure PIC_device is made public and
6558 renamed to PIC16_device, the same for variable Pics which is renamed
6559 to Pics16. Updated all references to them.
6560 * src/pic16/glue.c (pic16glue): corrected bug with code
6561 initialization which bypassed the variable initializations block.
6563 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6564 COMPILE_FLAGS and added the --nostdinc option
6566 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6568 * device/include/mc68hc908jb8.h: Register defs for another member
6569 of the hc08 family. Contributed by Bjorn Bringert - thanks!
6571 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6573 Documenting changes from previous commits.
6574 * configure.in (version 1.56),
6575 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6576 when generating output files to configure the pic16 library,
6577 but now I've commented it out, since gputils aren't installed in the
6578 SF compile farm, so library won't compile
6580 * device/lib/Makefile.in (version 1.56): initially I've added in
6581 target 'all' the prerequestive 'model-pic16' so it compiled the
6582 pic16 library, but now I've commented it out for the same reasons
6584 * added targets 'model-pic16' and 'objects-pic16' to compile the
6586 * added target 'port-specific-objects-pic16' to handle the
6587 generated libraries and copy them into the build/ directory
6588 * added target 'clean-intermediate-pic16' to clean intermediate
6589 files into pic16 directory
6590 * in target 'installdirs' added line to create directory pic16 in
6591 the installation path
6593 * device/include/Makefile.in (version 1.11): in target 'install'
6594 added lines to copy all header files to installation path,
6595 * in target 'installdirs' added line create directory for pic16
6596 headers in the installation path
6598 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6611 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6612 option so that it actually works. Made it specific to the z80, since
6613 the gbz80 doesn't have these kinds of I/O ports.
6615 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6617 * device/include/z180.h,

6630 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6632 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6633 changed interrupt vector table generation to only emit declared vectors.

6639 Mainly changes to support compilation of the device libraries
6640 * src/pic16/device.c: stack is allocated via symbol and not
6641 via literal number. The symbol is placed in the corresponding
6642 position of the data ram
6643 * (pic16_dump_section): relocatable and absolute uninitialized
6644 data are now emitted in sorted order to reduce section naming,
6645 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6646 weren't marked as being in the access bank,
6648 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6650 Added portion of GNU PIC Library under the directory
6651 device/include/pic16 and device/lib/pic16. These files
6652 contain the declarations of SFRs for the PIC18Fxx2 devices.
6653 The directory is initialized via configure from toplevel.
6655 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6657 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6658 the spilllocations to be compared correctly
6660 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6662 * src/SDCCast.c (decorateType): fixed bug introduced today
6664 2004-01-12 Borut Razem <borut.razem AT siol.net>

6682 * doc/sdccman.lyx: Moved and added some sections, small changes
6683 all over. Telling LaTeX to be less strict with word spacing
6684 to better keep the right margin. Changed some notes about
6685 maintainance of the ports in section 3.2.1 - is it OK like this?
6687 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6724 UPPER for immediate operands,
6725 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6727 * src/pic16/peeph.def: all peepholes with movff are commented out,
6728 because there is a problem in the pcode peep optimizer,
6729 * src/pic16/ralloc.c: the register allocator can now reuse local

6731 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6733 Added file src/pic16/NOTES with information about program writing on
6734 the current port version.

6743 * src/SDCCmain.c : fixed #872250: -l command line defined library
6744 files are scanned before standard library files
6746 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6766 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6769 * src/z80/main.c: added missed needLinkerScript flags (more than
6770 one port structure defined in these file)
6771 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6787 needLinkerScript flag
6789 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6790 * src/pic/glue.c: added variable udata_section_name to
6791 override default uninitialized data segment definition for
6792 devices only with SHAREBANK memory (reported from Erik Epetrich)
6793 * (pic14emitOverlay): modified to emit a commented overlay segment
6794 directive when no overlay data exist
6795 * (picglue): modified to emit uninitialized data segment
6796 according to udata_section_name

6806 2004-01-07 Borut Razem <borut.razem AT siol.net>
6808 * support/scripts/sdcc.nsi: update PATH
6809 * support/scripts/sdcc.ico: craeted

6822 include information about variables allocated to the overlay
6825 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6827 * as/mcs51/lkmain.c: Help about -Y option

6839 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6841 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6842 (default behaviour).
6844 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6846 A python script to validate compiler diagnostic messages. It can be
6847 used to verify that sdcc complains about bad c source code and
6848 gives a good location of the error.
6849 * support/valdiag/Makefile,
6850 * support/valdiag/valdiag.py,
6851 * support/valdiag/tests/*
6853 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6868 Bug reported from Jesus Calvino-Fraga
6870 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6872 * sdcc.spec: updated
6873 * device/include/Makefile.in: don't install CVS directories
6874 * device/lib/Makefile.in: added removal of CVS directories after install
6875 * doc/Makefile: fixed install, added local_icons
6876 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6877 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6878 * src/ds390/gen.c (genRightShift): fixed bug #870788
6879 * src/SDCCast.c (decorateType): fixed bug #870781
6881 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6883 PIC16 port related changes:
6884 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6885 added variable stackPos,
6887 * gen.c: genCall, assignResultValue: added support for
6888 pushing/retrieving function parameters to/from stack,
6889 genFunction,genEndFunction: setup stack frame for the
6891 genAddrOf: will be changed according to bug 863624
6893 * added files genutils.c and genutils.h which contain gen*
6894 debugged and optimised functions extracted from gen.c
6896 * glue.c: added variable 'externs' which holds extern symbols,
6897 pic16emitRegularMap: is modified to properly handle relocatable
6898 symbols under the new scheme,
6899 pic16createInterruptVect: is modified
6900 pic16printPublics: is modified to emit 'global' assembler directives,
6901 added pic16_printExterns to print extern symbols,
6902 pic16glue: initializes stack/frame pointer in the beginning of
6903 the assembly output. Temporary hack, will be corrected later,
6904 because gplink yet does not support stack and SDCC does not
6905 yet support a type of crt0.o object to create the final binary.
6907 * Removed many lines that contain 8051 legacy code.
6908 * The code is finally placed under a 'code' directive.
6909 * Added port specific options.
6911 * _process_pragma: simplified since now we do not need *special*
6912 include file to define SFR registers. But a separate header
6913 will be needed. This will be developed later.
6914 * _pic16_parseOptions: added, parses port specific options:
6915 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6916 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6917 --preplace-udata-with=
6919 * _pic16_setDefaultOptions: modified to initialize section names,
6920 but hack is temporarly out of order since it needs improvement.
6921 * _pic16_genAssemblerPreamble: configuration words are emitted by
6922 their address instead of their name. This part is incomplete and
6923 supports only the 18Fxx2 devices. Other devices will emit an error
6924 during assembly since they do not contain the same set of config
6926 * _pic16_genIVT: is modified,
6928 * pcode.c: added definitions for some hardware registers that are needed
6930 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6931 All PCI entries are updated. Now LFSR is supported.
6932 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6933 * added pic16_newpCodeOpLit2 to support instructions with
6934 two literal arguments
6935 * pic16_pCode2str: corrected code that emits assembler instructions
6936 with two literal operands and those that have an access bit modifier
6937 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6938 this fixes a bug which caused some labels to be lost, when an
6939 assembler directive was added, i.e. banksel,
6940 * pic16_FixRegisterBanking: improved logic that causes the insertion
6942 * InlineFunction: functions that are called once, are not any more
6943 inlined. This can be a port option in the future,
6945 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6947 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6948 hold the corresponding uninitialized symbols,
6949 * pic16_allocProcessorRegister: registers have explicit marked the
6951 * pic16_allocInternalRegister: registers are explicit marked as
6953 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6954 processing list, so bit registers were lost,
6957 * ralloc.h: added field 'accessBank' and original symbol operand
6958 in register definition,
6959 * removed the field isMapped from register definition,
6961 ** Several functions have been removed from various sources:
6962 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6963 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6964 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6965 pic16_assignRelocatableRegisters
6967 ** others have been introduced:
6968 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6969 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6971 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6973 * support/scripts/inc2h.pl: changed definition of BIT_AT
6974 to emit 'sbit at' instead of 'bit at'. This was a request.
6976 PIC16 port related preliminary changes:
6977 * gen.c: prefixed function popRegFromString with
6978 pic16_ and all references to it corrected
6979 * pcode.c: all pic16_pc_* hardware registers prefixed
6980 with underscore (_),
6981 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6982 * ralloc.c: newReg(): when register is REG_SFR then
6983 set address to rIdx,
6984 pic16_allocProcessorRegister(): marks register wasUsed=0
6985 pic16_writeUsedRegs(): added a call to assign processor
6986 registers via pic16_assignFixedRegisters
6988 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6990 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6991 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6992 variables in unused register banks. Also the SSEG is placed
6993 wherever there is enough space for it, and IDATA can be anywhere
6994 in internal RAM. For now compile using -Wl-Y[stack_size].
6995 The mem file is different for this option as well, since it
6996 makes no sense of talking about DSEG lenght.
6998 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7000 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8032 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8034 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8047 A few small changes that speed up the peephole optimizer.
8051 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8053 Try to make the peephole optimizer smarter by maintaining
8054 an association between the assembly source code and the
8055 iCodes that originated them. Put this information to use
8056 with a new peephole rule condition "notVolatile" so that
8057 the rules can be aggressive yet still safe.
8062 * src/mcs51/peeph.def
8064 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8068 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8069 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8070 if the left or right operand symbols have the accuse flag set.
8072 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8074 Changed the type of the result of the ! (NOT) operator to char;
8075 previously it returned the same type as the source. This allows
8076 us to eliminate all the genFloatNot functions (all of its target
8077 implementations were very buggy) since !float can use the same
8080 * src/SDCCicode.c (ast2iCode): ! returns char

8089 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8090 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8091 during interrupts. Ensure WSAVE is located at a shared bank address.
8092 2. Fixed page selection in some places
8093 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8094 the registers name strings.
8095 4. Fixed "signed / unsigned compare" compiler warnings.
8096 5. The PIC port manages its own allocation of the general purpose
8097 registers, but makes no attempt to reuse them. As a result when
8098 compiling it soon runs out of general purpose registers. Some
8099 additional code was added to the files pcode.c and device.c to walk
8100 through the function call tree and rename the registers so that they
8110 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8111 genPlus() & genMinus() when the result is the same as left or right

8117 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8119 Made bitfield a distinct type from bit so that bitfields
8120 convert as per ANSI C and bits retain their traditional
8121 boolean style behaviour. Implemented bitfield support in
8129 * src/ds390/gen.c: bit v bitfield split
8130 * src/z80/gen.c: New support for bitfields
8131 * support/regression/tests/bitfields.c: reenabled z80,
8134 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8136 Rules 246.x, 247.x relate to bitfields, the others speed up
8137 access to xdata mapped I/O devices.
8139 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8141 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8143 Cleaned up genPackBits and genUnpackBits and added two helper
8144 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8145 for literal assignments in genPackBits (thanks to Frieder for
8151 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8153 Fixed bug #748310 (pointer to function type mishandled when the
8154 function name is omitted). Also fixed a SIGSEGV when a function
8155 attribute (reentrant, etc) is used on a non-function or on a
8156 function but misplaced before the parameter list.
8158 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8160 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8183 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8185 Made the constant following the "interrupt" keyword optional. If
8186 omitted, the function will not automatically be given an entry
8187 in the interrupt vector table (similar to #pragma NOIV, but
8188 less syntacticly kludgy). The interrupt number is also now
8189 range checked. Also fixed a bug in the high order bit example

8210 unsigned, but are signed by default
8211 * src/SDCCval.c (constVal): rearranged
8212 * src/SDCCval.c (valMod): preliminary fix
8213 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8630 condition and ignore commands.
8632 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8634 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
8635 is in parts still quite out of date, I did changes as far as I felt makes sense
8636 for a non-native english speaker.
8637 Please feel free to add to the manual or to correct my changes.
8638 * doc/Makefile: undid touching the date of intermediate tex files.
8640 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8657 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
8658 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8659 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8660 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
8663 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8665 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8666 the regression tests I'm not brave enough to enable 245.b, 245.c
8667 * doc/sdccman.lyx: added latex preamble for hyperref package.
8668 Using pdflatex this will give you a hyperlinked pdf file with
8669 bookmarks. (prepend '%' before /usepackage if this breaks something)
8671 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8683 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
8685 Applied patch from bug 737905 (renamed yylineo to mylineno):
8692 * src/pic16/pcode.c: Cleaned warnings
8693 * src/pic16/pcodeflow.c: Cleaned warnings
8694 * src/pic16/pcoderegs.c: Cleaned warnings

8705 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
8707 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8709 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8710 it can be defined with CFLAGS when running configure
8711 * src/SDCCmain.c: fixed compiling + linking with object files
8713 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8715 * configure.in: configure for pic16 port,
8716 added --disable-pic16-port
8717 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8718 * src/SDCCmain.c: linkOptions is changed to set *,
8719 added if/endif conditional macros to remove options help
8720 messages from optionsTable when a port is not configured, added
8721 support for the PIc16 port in the ports table, when executing
8722 the compiler with no port specified on command line, a default
8723 port is selected with the new macro DEFAULT_PORT which is
8724 defined in port.h, in setDefaultOptions() linkOptions is removed
8725 from initialization assignment, since now it is a set,
8726 parseCmdLine uses setParseWithComma for linkOptions, in
8727 linkEdit() linkOptions are accessed with new function indexSet()
8728 which returns the i'th item of a set variable. See SDCCset.c, in
8729 linkEdit() when calling buildCmdLine(), added linkOptions as
8730 last argument. Now users can pass arguments to gplink via the
8731 -Wl option, main() uses pic16glue() to glue up pic16 programs
8732 * src/SDCCpeeph.c: various changes to support pic16
8733 * src/SDCCset.c: added function void *indexSet(set *, int) to

8739 added macro DEFAULT_PORT
8740 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
8741 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8743 * src/pic16/glue.c: commented out some error producing lines
8744 * src/pic16/main.c: __config directives are commented out to stop
8745 gpasm complaining and test the linkage with gplink, _linkCmd and
8746 _asmCmd changed to be more gplink and gpasm friendly
8747 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8748 produced an error when parsed, peep rule 12 is added to utilize
8749 movff, but it is commented out since the pCode does not support
8750 yet a command with 2 address arguments
8752 2003-05-18 <johan AT balder>
8754 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8755 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8756 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

8774 on entry now. Add tbreak. Other enhancements and fixes for use
8777 2003-05-12 Borut Razem <borut.razem AT siol.net>
8779 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8781 2003-05-11 Borut Razem <borut.razem AT siol.net>
8783 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8784 the path of bin directory, so that PATH is the only env. variable, which has to be set
8785 in case of standard installation.
8786 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9815 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9817 * in \sdcc\as\mcs51\ changed these files in order to create an
9818 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9819 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9820 following files to include the previous two files: aslink.dsp,
9821 Makefile.aslink, Makefile.bcc, and Makefile.in.
9823 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9824 .adb instead of .cdb
9826 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9828 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9829 value from option --iram-size.
9831 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9833 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9836 2002-09-18 <wiml AT hhhh.org>
9838 * SDCClrange.h: exposed setFromRange() and setToRange()
9839 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9840 packRegsForAccUse() (bug 542397)
9841 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9842 multiple times and emitting the fetch operations more than once
9843 added aopGetUsesAcc() function to allow binary operators to
9844 fetch their operands in the correct order; made genMinus() emit
9845 compact code for X = LITERAL - Y
9847 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9848 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9849 sprintf() in line 1267.
9851 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9852 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9855 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9856 Changes to aslink (All the changes are marked with 'JCF'):
9858 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9861 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9862 area BSEG. Also moves, if possible, the DATA area down into the internal
9863 ram so more space is available.
9865 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9868 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9869 not bytes. Function summary() which creates a memory usage summary
9870 file with extension .mem. Reports of overlaping stack and small stack
9871 size. If the space for the stack is less than 16 bytes aslink trows a
9874 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9875 the 8051. Option 'y' for memory summary output file.
9877 Changes to sdcc (All the changes are marked with 'JCF'):
9879 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9881 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9882 overlaying area for it (uses RegBankUsed[4]).
9884 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9885 bank zero as used by default. By default aslink locates the stack
9886 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9887 the creation of the .mem file. Delegates the allocation of data area
9888 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9889 the begining of the stack area to aslink.
9891 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9892 glue() in SDCCglue.c creates an area for it.
9894 2002-09-03 Borut Razem <borut.razem AT siol.net>
9895 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9896 sdcc/src/pic/glue.c:
9897 introduced atexit() handler for teporay files removal in case of
9898 errors, assertions, ...
9900 2002-08-29 Borut Razem <borut.razem AT siol.net>
9901 * sdcc/support/cpp2/auto-host_vc_in.h:
9902 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9903 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9904 Maybe there is a similar problem with BORLANDC? It should be checked!
9906 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9907 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9908 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9909 was not executed, and the compiler (cl) launched a warning:
9910 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9912 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9925 - added Release configuration in VS projects
9926 - review of compiler an linker options
9927 - VC .exe files are generated in bin_vc directory, not to interfere
9928 with binaries generated from other projects (cygwin, mingw, bcc ...)
9930 * sdcc/src/yacc.dsp: added
9932 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9933 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9934 and insert the version number definitions from .version
9936 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9938 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9942 removed from CVS, generated automatically
9944 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9945 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9947 2002-08-11 Borut Razem <borut.razem AT siol.net>
9948 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9950 2002-08-10 Borut Razem <borut.razem AT siol.net>
9951 * src/SDCCmain.c (main):
9952 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9953 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9954 The consequence was that some temporary files were not removed.
9957 unification of code in functions tempfilename() and tempfile():
9958 function tempnam() is defined in Visual Studio 6.0 and .NET
9960 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9962 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9963 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9964 - removed compiler command line option /WX: Treats all warnings as errors
9965 - update a list of source files, included into the project
9967 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9968 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9969 changed project type to Generic Project so that can be correcly converted to VS.NET project
9971 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9973 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9975 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9977 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9978 added return 0 statements after assert() to make compiler happy
9980 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9981 added newline in the def file to keep MSC compiler satisfied
9983 * sdcc/src/z80/gen.c:
9984 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9985 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9986 - solved MSC error in function aopDump()
9988 * sdcc_vc.h: define PREFIX as "\\sdcc"
9990 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9991 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10045 Compiler generated registers for interrupt context saving
10046 were not getting allocated.
10048 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

10163 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10165 * sdcc/src/SDCCloop.c:
10166 Previous fix was not good. basic blocks that have "break" or "return" are
10167 not really partof a loop , but live ranges used in these blocks should
10168 be live thru the entire loop, so set partOfLoop but don't add them to
