271 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
274 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
276 * src/.version: increased version number to 2.5.5

278 linking is done manually in pic16 port's _linkEdit,
279 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
280 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

2744 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2746 * device/lib/printf_large.c: removed inline assembly for portability and
2747 readability. Use printf_fast if speed or size are more important.
2748 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2749 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2751 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2753 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2754 prevent compiler warning
2756 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2758 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2759 moved to level 0 and declared as static. Also they are explicit
2760 placed in access bank. This was necessery because some times they
2761 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2762 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2763 optimizations. Currently only compare to unsigned char is implemented,
2764 * src/pic16/gen.c: added fReturnIdx array,
2765 * (struct resolvedIfx) is moved to gen.h and made public,
2766 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2767 * (aopForSym): added an optimization to directly store in stack of
2768 the operand of a SEND iCode,
2769 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2770 but as registers instead (AOP_REG) using the fReturnIdx array,
2771 * (pic16_freeAsmop): remove the freed register from the
2772 _G.sregsAlloc field,
2773 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2774 a compare of 'WREG',
2775 * (pic16_popGetTempRegCond): changed function prototype, now
2776 function takes also a bitVector argument v which holds the current
2777 set of registers that are allocated for stack access by aopForSym,
2778 registers allocated in aopForSym for accessing stack symbols are not
2779 any more part of the functions usedRegs field,
2780 * (genCall): some times aopOp is called for a stack variable to be
2781 send, aopForSym might perform the push, if this is true make sure
2782 that genCall doesn't push the variable twice by testing _G.resDirect,
2783 * (genFunction): changed testing for unspecified interrupt number
2784 from 256 to INTNO_UNSPEC,
2785 * modified selection scheme of frame pointer generation. Previously
2786 if function did use local registers a frame pointer was generated,
2787 now a frame pointer is generated only if function has arguments
2788 (that need PLUSW2 register access), or has stack arguments, or the
2789 compiler is not instructed to omit the frame pointer,
2790 * (genEndFunction): before restoring local registers that were saved
2791 in the function preamble, also restore the registers that *might*
2792 have been allocated for stack access,
2793 * (genRet): removed some old comments,
2794 * (genCmp, the active (RN's) version): added a call to the
2795 pic16_genCmp_special function to perform the compare with a more
2796 robust and optimized way,
2797 * (genInline): a feature has been added in inline code generation,
2798 which allows a wildcard variable substitution when writing inline
2799 assembly. Code is incomplete and experimental therefore undocumented,
2800 * (genCast): changed order of aopOp for result and right to allow
2801 aopForSym to directly load the result if possible,
2802 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2803 perform an optimized compare on some selected special occasions,
2804 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2805 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2806 generate an IVT any more,
2807 * src/pic16/main.c (pic16_optionsTable): added command line option
2809 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2810 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2812 * src/pic16/NOTES: Raphael Neider added in list of active developers
2813 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2814 jumptable_end to prevent bug #,
2815 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2816 inCond and outCond fields,
2817 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2818 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2819 turn off register spilling,
2820 * (packRegsForOneUse): synced with other ports' versions although it
2821 is not used currently,
2822 * (pic16_packRegisters): added an optimization while reading
2823 structure bitfields, some registers may be saved (malloc code is
2824 decreased by 80 bytes)
2826 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2828 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2829 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2830 this can be optimized more?
2832 2005-03-10 Raphael Neider <rneider AT web.de>
2834 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2835 genNearPointerGet): (hopefully) fixed access to bitfields via
2836 pointers (p->bitN = x; and x = p->bitN; failed)
2838 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3451 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
3453 (setFromConditionArgs): friendly operand parser for peephole rules,
3454 (operandBaseName, operandsNotRelated): new peephole condition
3455 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3456 architecture specific register naming into account, handles n-way
3457 comparisons, and supports quoted literals
3458 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

3468 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3470 Adding support for replacing ljmps with sjmps in jumptables
3471 generated for switch statements. For now you need to set the
3472 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3473 Now 4 algorithms for mcs51 jumptable generation are used:
3474 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3475 addresses loaded pc-relative for up to 112 cases and stack-pushing
3476 target addresses loaded with offset from dptr for up to 256 cases.
3478 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3479 * src/mcs51/main.c: adapted constants for switch table generation
3480 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3502 Large cummulative patch for pic16 port.
3503 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3504 to call when a stack overflow occurs,
3505 * (malloc.h): added CVS Id tag,
3506 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3508 * added libc directory. The current version of LibC contains string
3509 functions, ctype functions and macros and some functions of the
3510 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3511 be extensively tested in the future. Standard disclaimer here.
3512 Library is not automatically build yet. But one can build it by
3513 invoking 'make' inside the libc directory.
3514 * added ADC library under libio. Preliminary version yet.
3516 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3523 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3524 * (pic16_storeForReturn): optimized return of 0,
3525 * (genCmp): experimental code for new genCmp which uses PIC18's
3526 special compare&skip instructions. Initial tests fail some times
3527 with variables grater than 1 byte in size, so new code is disabled,
3528 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3530 * (genCast): began a fix to optimize the casting of a bit to another
3531 bit, now assigning a bitfield to another bitfield will fail, sorry,
3532 * src/pic16/main.c: disabled the use of lr-support feature,
3533 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3534 * added some function prototypes, added function _debugf prototype,
3535 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3536 bits with offset (case PO_GPR_BIT),
3537 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3539 * (isBankInstruction): modified to return 0 for no banking instruction,
3540 and 1 for banking instruction,
3541 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3542 caused stop processing pCodes after a inline assembly block,
3543 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3544 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3545 registers when it shouldn't,
3546 * src/pic16/ralloc.c (allocReg): add preliminary support for
3547 supporting a limited set of temporary registers,
3549 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3551 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3552 genDataPointerSet): ensure assignments always copy in MSB to LSB
3554 (loadRegFromAop): recognize CLRH optimization,
3555 (genFunction): optimize RECEIVE iCodes in reentrant functions
3557 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3559 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3560 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3562 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3568 * device/lib/_gptrget.c (_gptrget),
3569 * device/lib/_gptrgetc.c (_gptrgetc),
3570 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
3571 instead of sjmp to ret
3572 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3573 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3575 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6547 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
6549 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
6551 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
6554 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6556 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6557 loaded with the linker search paths (-L arguments) and the libraries
6558 to be linked with the current source (-l arguments). Changes
6559 currently will affect only the pic16 port.
6560 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6561 include path the port specific paths and port specific libraries,
6562 * gplink command now contains the $3 argument,
6563 * src/pic16/device.h,
6564 * src/pic16/device.c,: structure PIC_device is made public and
6565 renamed to PIC16_device, the same for variable Pics which is renamed
6566 to Pics16. Updated all references to them.
6567 * src/pic16/glue.c (pic16glue): corrected bug with code
6568 initialization which bypassed the variable initializations block.
6570 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6571 COMPILE_FLAGS and added the --nostdinc option
6573 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6575 * device/include/mc68hc908jb8.h: Register defs for another member
6576 of the hc08 family. Contributed by Bjorn Bringert - thanks!
6578 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6580 Documenting changes from previous commits.
6581 * configure.in (version 1.56),
6582 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6583 when generating output files to configure the pic16 library,
6584 but now I've commented it out, since gputils aren't installed in the
6585 SF compile farm, so library won't compile
6587 * device/lib/Makefile.in (version 1.56): initially I've added in
6588 target 'all' the prerequestive 'model-pic16' so it compiled the
6589 pic16 library, but now I've commented it out for the same reasons
6591 * added targets 'model-pic16' and 'objects-pic16' to compile the
6593 * added target 'port-specific-objects-pic16' to handle the
6594 generated libraries and copy them into the build/ directory
6595 * added target 'clean-intermediate-pic16' to clean intermediate
6596 files into pic16 directory
6597 * in target 'installdirs' added line to create directory pic16 in
6598 the installation path
6600 * device/include/Makefile.in (version 1.11): in target 'install'
6601 added lines to copy all header files to installation path,
6602 * in target 'installdirs' added line create directory for pic16
6603 headers in the installation path
6605 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6618 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6619 option so that it actually works. Made it specific to the z80, since
6620 the gbz80 doesn't have these kinds of I/O ports.
6622 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6624 * device/include/z180.h,

6637 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6639 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6640 changed interrupt vector table generation to only emit declared vectors.
6641 * device/include/Makefile.in: added missing backslash
6642 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
6644 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6646 Mainly changes to support compilation of the device libraries
6647 * src/pic16/device.c: stack is allocated via symbol and not
6648 via literal number. The symbol is placed in the corresponding
6649 position of the data ram
6650 * (pic16_dump_section): relocatable and absolute uninitialized
6651 data are now emitted in sorted order to reduce section naming,
6652 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6653 weren't marked as being in the access bank,
6655 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6657 Added portion of GNU PIC Library under the directory
6658 device/include/pic16 and device/lib/pic16. These files
6659 contain the declarations of SFRs for the PIC18Fxx2 devices.
6660 The directory is initialized via configure from toplevel.
6662 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6664 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6665 the spilllocations to be compared correctly
6667 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6669 * src/SDCCast.c (decorateType): fixed bug introduced today
6671 2004-01-12 Borut Razem <borut.razem AT siol.net>
6673 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

6676 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6678 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6679 in simpler and even better code
6681 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
6683 * src/SDCCicode.c (operandOperation): fixed bug #874819

6689 * doc/sdccman.lyx: Moved and added some sections, small changes
6690 all over. Telling LaTeX to be less strict with word spacing
6691 to better keep the right margin. Changed some notes about
6692 maintainance of the ports in section 3.2.1 - is it OK like this?
6694 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6696 SDCC source changes:
6697 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6731 UPPER for immediate operands,
6732 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6734 * src/pic16/peeph.def: all peepholes with movff are commented out,
6735 because there is a problem in the pcode peep optimizer,
6736 * src/pic16/ralloc.c: the register allocator can now reuse local
6737 function symbols for another function. This saves register usage.
6738 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6740 Added file src/pic16/NOTES with information about program writing on
6741 the current port version.

6773 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6776 * src/z80/main.c: added missed needLinkerScript flags (more than
6777 one port structure defined in these file)
6778 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6794 needLinkerScript flag
6796 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6797 * src/pic/glue.c: added variable udata_section_name to
6798 override default uninitialized data segment definition for

6800 * (pic14emitOverlay): modified to emit a commented overlay segment
6801 directive when no overlay data exist
6802 * (picglue): modified to emit uninitialized data segment
6803 according to udata_section_name

6813 2004-01-07 Borut Razem <borut.razem AT siol.net>
6815 * support/scripts/sdcc.nsi: update PATH
6816 * support/scripts/sdcc.ico: craeted
6818 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

6829 include information about variables allocated to the overlay
6832 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6834 * as/mcs51/lkmain.c: Help about -Y option

6846 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6848 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6849 (default behaviour).
6851 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6853 A python script to validate compiler diagnostic messages. It can be
6854 used to verify that sdcc complains about bad c source code and
6855 gives a good location of the error.
6856 * support/valdiag/Makefile,
6857 * support/valdiag/valdiag.py,
6858 * support/valdiag/tests/*
6860 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6862 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6873 * src/common.h: added ifndef/define/endif macros
6874 around the header file.
6875 Bug reported from Jesus Calvino-Fraga
6877 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6879 * sdcc.spec: updated
6880 * device/include/Makefile.in: don't install CVS directories
6881 * device/lib/Makefile.in: added removal of CVS directories after install
6882 * doc/Makefile: fixed install, added local_icons
6883 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6884 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6885 * src/ds390/gen.c (genRightShift): fixed bug #870788
6886 * src/SDCCast.c (decorateType): fixed bug #870781
6888 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6890 PIC16 port related changes:
6891 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6892 added variable stackPos,
6894 * gen.c: genCall, assignResultValue: added support for
6895 pushing/retrieving function parameters to/from stack,
6896 genFunction,genEndFunction: setup stack frame for the
6898 genAddrOf: will be changed according to bug 863624
6900 * added files genutils.c and genutils.h which contain gen*
6901 debugged and optimised functions extracted from gen.c
6903 * glue.c: added variable 'externs' which holds extern symbols,
6904 pic16emitRegularMap: is modified to properly handle relocatable
6905 symbols under the new scheme,
6906 pic16createInterruptVect: is modified
6907 pic16printPublics: is modified to emit 'global' assembler directives,
6908 added pic16_printExterns to print extern symbols,
6909 pic16glue: initializes stack/frame pointer in the beginning of
6910 the assembly output. Temporary hack, will be corrected later,
6911 because gplink yet does not support stack and SDCC does not
6912 yet support a type of crt0.o object to create the final binary.
6914 * Removed many lines that contain 8051 legacy code.
6915 * The code is finally placed under a 'code' directive.
6916 * Added port specific options.
6918 * _process_pragma: simplified since now we do not need *special*
6919 include file to define SFR registers. But a separate header
6920 will be needed. This will be developed later.
6921 * _pic16_parseOptions: added, parses port specific options:
6922 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6923 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6924 --preplace-udata-with=
6926 * _pic16_setDefaultOptions: modified to initialize section names,
6927 but hack is temporarly out of order since it needs improvement.
6928 * _pic16_genAssemblerPreamble: configuration words are emitted by
6929 their address instead of their name. This part is incomplete and
6930 supports only the 18Fxx2 devices. Other devices will emit an error
6931 during assembly since they do not contain the same set of config
6933 * _pic16_genIVT: is modified,
6935 * pcode.c: added definitions for some hardware registers that are needed
6937 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6938 All PCI entries are updated. Now LFSR is supported.
6939 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6940 * added pic16_newpCodeOpLit2 to support instructions with
6941 two literal arguments
6942 * pic16_pCode2str: corrected code that emits assembler instructions
6943 with two literal operands and those that have an access bit modifier
6944 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6945 this fixes a bug which caused some labels to be lost, when an
6946 assembler directive was added, i.e. banksel,
6947 * pic16_FixRegisterBanking: improved logic that causes the insertion
6949 * InlineFunction: functions that are called once, are not any more
6950 inlined. This can be a port option in the future,
6952 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6954 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6955 hold the corresponding uninitialized symbols,
6956 * pic16_allocProcessorRegister: registers have explicit marked the
6958 * pic16_allocInternalRegister: registers are explicit marked as
6960 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6961 processing list, so bit registers were lost,
6964 * ralloc.h: added field 'accessBank' and original symbol operand
6965 in register definition,
6966 * removed the field isMapped from register definition,
6968 ** Several functions have been removed from various sources:
6969 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6970 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6971 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6972 pic16_assignRelocatableRegisters
6974 ** others have been introduced:
6975 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6976 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6978 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6980 * support/scripts/inc2h.pl: changed definition of BIT_AT
6981 to emit 'sbit at' instead of 'bit at'. This was a request.
6983 PIC16 port related preliminary changes:
6984 * gen.c: prefixed function popRegFromString with
6985 pic16_ and all references to it corrected
6986 * pcode.c: all pic16_pc_* hardware registers prefixed
6987 with underscore (_),
6988 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6989 * ralloc.c: newReg(): when register is REG_SFR then
6990 set address to rIdx,
6991 pic16_allocProcessorRegister(): marks register wasUsed=0
6992 pic16_writeUsedRegs(): added a call to assign processor
6993 registers via pic16_assignFixedRegisters
6995 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6997 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6998 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6999 variables in unused register banks. Also the SSEG is placed
7000 wherever there is enough space for it, and IDATA can be anywhere
7001 in internal RAM. For now compile using -Wl-Y[stack_size].
7002 The mem file is different for this option as well, since it
7003 makes no sense of talking about DSEG lenght.
7005 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7007 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7008 in certain cases, e.g. when ROM assignment, patch provided
7009 from Albert den Haan.
7011 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8030 these ports have their own __sdcc_external_start()
8032 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8034 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8035 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8036 type for bits was changed. It resulted in bit variables becoming
8037 global, which is not permitted in PIC 14 assembly output.
8039 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8041 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8054 A few small changes that speed up the peephole optimizer.
8058 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8060 Try to make the peephole optimizer smarter by maintaining
8061 an association between the assembly source code and the
8062 iCodes that originated them. Put this information to use
8063 with a new peephole rule condition "notVolatile" so that
8064 the rules can be aggressive yet still safe.
8069 * src/mcs51/peeph.def
8071 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8075 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8076 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8077 if the left or right operand symbols have the accuse flag set.
8079 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8081 Changed the type of the result of the ! (NOT) operator to char;
8082 previously it returned the same type as the source. This allows
8083 us to eliminate all the genFloatNot functions (all of its target
8084 implementations were very buggy) since !float can use the same
8087 * src/SDCCicode.c (ast2iCode): ! returns char

8096 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8097 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8098 during interrupts. Ensure WSAVE is located at a shared bank address.
8099 2. Fixed page selection in some places
8100 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8101 the registers name strings.
8102 4. Fixed "signed / unsigned compare" compiler warnings.
8103 5. The PIC port manages its own allocation of the general purpose
8104 registers, but makes no attempt to reuse them. As a result when
8105 compiling it soon runs out of general purpose registers. Some
8106 additional code was added to the files pcode.c and device.c to walk
8107 through the function call tree and rename the registers so that they
8117 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8118 genPlus() & genMinus() when the result is the same as left or right

8124 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8126 Made bitfield a distinct type from bit so that bitfields
8127 convert as per ANSI C and bits retain their traditional
8128 boolean style behaviour. Implemented bitfield support in
8136 * src/ds390/gen.c: bit v bitfield split
8137 * src/z80/gen.c: New support for bitfields
8138 * support/regression/tests/bitfields.c: reenabled z80,
8141 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8143 Rules 246.x, 247.x relate to bitfields, the others speed up
8144 access to xdata mapped I/O devices.
8146 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8148 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8150 Cleaned up genPackBits and genUnpackBits and added two helper
8151 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8152 for literal assignments in genPackBits (thanks to Frieder for
8158 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8160 Fixed bug #748310 (pointer to function type mishandled when the
8161 function name is omitted). Also fixed a SIGSEGV when a function
8162 attribute (reentrant, etc) is used on a non-function or on a
8163 function but misplaced before the parameter list.
8165 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8167 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8190 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8192 Made the constant following the "interrupt" keyword optional. If
8193 omitted, the function will not automatically be given an entry
8194 in the interrupt vector table (similar to #pragma NOIV, but
8195 less syntacticly kludgy). The interrupt number is also now
8196 range checked. Also fixed a bug in the high order bit example

8210 * src/SDCCicode.c (operandOperation): rewritten some ops
8211 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8212 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8214 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8215 be re-activated by defining REDUCE_LITERALS)
8216 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8217 unsigned, but are signed by default
8218 * src/SDCCval.c (constVal): rearranged
8219 * src/SDCCval.c (valMod): preliminary fix
8220 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8643 for a non-native english speaker.
8644 Please feel free to add to the manual or to correct my changes.

8672 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8673 the regression tests I'm not brave enough to enable 245.b, 245.c
8674 * doc/sdccman.lyx: added latex preamble for hyperref package.
8675 Using pdflatex this will give you a hyperlinked pdf file with
8676 bookmarks. (prepend '%' before /usepackage if this breaks something)

8692 Applied patch from bug 737905 (renamed yylineo to mylineno):
8699 * src/pic16/pcode.c: Cleaned warnings
8700 * src/pic16/pcodeflow.c: Cleaned warnings
8701 * src/pic16/pcoderegs.c: Cleaned warnings

8714 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8716 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8717 it can be defined with CFLAGS when running configure
8718 * src/SDCCmain.c: fixed compiling + linking with object files
8720 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8722 * configure.in: configure for pic16 port,
8723 added --disable-pic16-port
8724 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8725 * src/SDCCmain.c: linkOptions is changed to set *,
8726 added if/endif conditional macros to remove options help
8727 messages from optionsTable when a port is not configured, added
8728 support for the PIc16 port in the ports table, when executing
8729 the compiler with no port specified on command line, a default
8730 port is selected with the new macro DEFAULT_PORT which is
8731 defined in port.h, in setDefaultOptions() linkOptions is removed
8732 from initialization assignment, since now it is a set,
8733 parseCmdLine uses setParseWithComma for linkOptions, in
8734 linkEdit() linkOptions are accessed with new function indexSet()
8735 which returns the i'th item of a set variable. See SDCCset.c, in
8736 linkEdit() when calling buildCmdLine(), added linkOptions as
8737 last argument. Now users can pass arguments to gplink via the
8738 -Wl option, main() uses pic16glue() to glue up pic16 programs
8739 * src/SDCCpeeph.c: various changes to support pic16

8748 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8750 * src/pic16/glue.c: commented out some error producing lines
8751 * src/pic16/main.c: __config directives are commented out to stop
8752 gpasm complaining and test the linkage with gplink, _linkCmd and
8753 _asmCmd changed to be more gplink and gpasm friendly
8754 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8755 produced an error when parsed, peep rule 12 is added to utilize
8756 movff, but it is commented out since the pCode does not support
8757 yet a command with 2 address arguments
8759 2003-05-18 <johan AT balder>
8761 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8762 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8781 on entry now. Add tbreak. Other enhancements and fixes for use
8784 2003-05-12 Borut Razem <borut.razem AT siol.net>
8786 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8788 2003-05-11 Borut Razem <borut.razem AT siol.net>
8790 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8791 the path of bin directory, so that PATH is the only env. variable, which has to be set
8792 in case of standard installation.
8793 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9822 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9824 * in \sdcc\as\mcs51\ changed these files in order to create an
9825 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9826 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9827 following files to include the previous two files: aslink.dsp,
9828 Makefile.aslink, Makefile.bcc, and Makefile.in.
9830 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9831 .adb instead of .cdb
9833 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9835 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9836 value from option --iram-size.
9838 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9840 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9843 2002-09-18 <wiml AT hhhh.org>
9845 * SDCClrange.h: exposed setFromRange() and setToRange()
9846 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9847 packRegsForAccUse() (bug 542397)
9848 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9849 multiple times and emitting the fetch operations more than once
9850 added aopGetUsesAcc() function to allow binary operators to
9851 fetch their operands in the correct order; made genMinus() emit
9852 compact code for X = LITERAL - Y
9854 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9855 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9856 sprintf() in line 1267.
9858 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9859 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9862 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9863 Changes to aslink (All the changes are marked with 'JCF'):
9865 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9868 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9869 area BSEG. Also moves, if possible, the DATA area down into the internal
9870 ram so more space is available.
9872 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9875 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9876 not bytes. Function summary() which creates a memory usage summary
9877 file with extension .mem. Reports of overlaping stack and small stack
9878 size. If the space for the stack is less than 16 bytes aslink trows a
9881 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9882 the 8051. Option 'y' for memory summary output file.
9884 Changes to sdcc (All the changes are marked with 'JCF'):
9886 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9888 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9889 overlaying area for it (uses RegBankUsed[4]).
9891 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9892 bank zero as used by default. By default aslink locates the stack
9893 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9894 the creation of the .mem file. Delegates the allocation of data area
9895 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9896 the begining of the stack area to aslink.
9898 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9899 glue() in SDCCglue.c creates an area for it.
9901 2002-09-03 Borut Razem <borut.razem AT siol.net>
9902 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9903 sdcc/src/pic/glue.c:
9904 introduced atexit() handler for teporay files removal in case of
9905 errors, assertions, ...
9907 2002-08-29 Borut Razem <borut.razem AT siol.net>
9908 * sdcc/support/cpp2/auto-host_vc_in.h:
9909 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9910 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9911 Maybe there is a similar problem with BORLANDC? It should be checked!
9913 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9914 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9915 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9916 was not executed, and the compiler (cl) launched a warning:
9917 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9919 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9932 - added Release configuration in VS projects
9933 - review of compiler an linker options
9934 - VC .exe files are generated in bin_vc directory, not to interfere
9935 with binaries generated from other projects (cygwin, mingw, bcc ...)
9937 * sdcc/src/yacc.dsp: added
9939 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9940 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9941 and insert the version number definitions from .version
9943 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9945 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9952 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9954 2002-08-11 Borut Razem <borut.razem AT siol.net>
9955 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9957 2002-08-10 Borut Razem <borut.razem AT siol.net>
9958 * src/SDCCmain.c (main):
9959 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9960 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9961 The consequence was that some temporary files were not removed.
9964 unification of code in functions tempfilename() and tempfile():
9965 function tempnam() is defined in Visual Studio 6.0 and .NET
9967 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9969 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9970 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9971 - removed compiler command line option /WX: Treats all warnings as errors
9972 - update a list of source files, included into the project
9974 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9975 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9976 changed project type to Generic Project so that can be correcly converted to VS.NET project
9978 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9980 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9982 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9984 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9985 added return 0 statements after assert() to make compiler happy
9987 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9988 added newline in the def file to keep MSC compiler satisfied
9990 * sdcc/src/z80/gen.c:
9991 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9992 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9993 - solved MSC error in function aopDump()
9995 * sdcc_vc.h: define PREFIX as "\\sdcc"
9997 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9998 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10170 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10172 * sdcc/src/SDCCloop.c:
10173 Previous fix was not good. basic blocks that have "break" or "return" are
10174 not really partof a loop , but live ranges used in these blocks should
