251 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
254 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
256 * src/.version: increased version number to 2.5.5
257 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
258 linking is done manually in pic16 port's _linkEdit,
259 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
260 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

2640 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2641 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2642 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2643 always available in leading double underscore form. The C99 support is
2644 mostly missing, but it's a start.
2645 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2646 reserved identifier "__data".

2724 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2726 * device/lib/printf_large.c: removed inline assembly for portability and
2727 readability. Use printf_fast if speed or size are more important.
2728 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2729 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2731 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2733 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2734 prevent compiler warning
2736 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2738 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2739 moved to level 0 and declared as static. Also they are explicit
2740 placed in access bank. This was necessery because some times they
2741 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2742 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2743 optimizations. Currently only compare to unsigned char is implemented,
2744 * src/pic16/gen.c: added fReturnIdx array,
2745 * (struct resolvedIfx) is moved to gen.h and made public,
2746 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2747 * (aopForSym): added an optimization to directly store in stack of
2748 the operand of a SEND iCode,
2749 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2750 but as registers instead (AOP_REG) using the fReturnIdx array,
2751 * (pic16_freeAsmop): remove the freed register from the
2752 _G.sregsAlloc field,
2753 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2754 a compare of 'WREG',
2755 * (pic16_popGetTempRegCond): changed function prototype, now
2756 function takes also a bitVector argument v which holds the current
2757 set of registers that are allocated for stack access by aopForSym,
2758 registers allocated in aopForSym for accessing stack symbols are not
2759 any more part of the functions usedRegs field,
2760 * (genCall): some times aopOp is called for a stack variable to be
2761 send, aopForSym might perform the push, if this is true make sure
2762 that genCall doesn't push the variable twice by testing _G.resDirect,
2763 * (genFunction): changed testing for unspecified interrupt number
2764 from 256 to INTNO_UNSPEC,
2765 * modified selection scheme of frame pointer generation. Previously
2766 if function did use local registers a frame pointer was generated,
2767 now a frame pointer is generated only if function has arguments
2768 (that need PLUSW2 register access), or has stack arguments, or the
2769 compiler is not instructed to omit the frame pointer,
2770 * (genEndFunction): before restoring local registers that were saved
2771 in the function preamble, also restore the registers that *might*
2772 have been allocated for stack access,
2773 * (genRet): removed some old comments,
2774 * (genCmp, the active (RN's) version): added a call to the
2775 pic16_genCmp_special function to perform the compare with a more
2776 robust and optimized way,
2777 * (genInline): a feature has been added in inline code generation,
2778 which allows a wildcard variable substitution when writing inline
2779 assembly. Code is incomplete and experimental therefore undocumented,
2780 * (genCast): changed order of aopOp for result and right to allow
2781 aopForSym to directly load the result if possible,
2782 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2783 perform an optimized compare on some selected special occasions,
2784 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2785 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2786 generate an IVT any more,
2787 * src/pic16/main.c (pic16_optionsTable): added command line option
2789 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2790 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2792 * src/pic16/NOTES: Raphael Neider added in list of active developers
2793 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2794 jumptable_end to prevent bug #,
2795 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2796 inCond and outCond fields,
2797 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2798 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2799 turn off register spilling,
2800 * (packRegsForOneUse): synced with other ports' versions although it
2801 is not used currently,
2802 * (pic16_packRegisters): added an optimization while reading
2803 structure bitfields, some registers may be saved (malloc code is
2804 decreased by 80 bytes)
2806 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2808 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2809 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2810 this can be optimized more?
2812 2005-03-10 Raphael Neider <rneider AT web.de>
2814 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2815 genNearPointerGet): (hopefully) fixed access to bitfields via
2816 pointers (p->bitN = x; and x = p->bitN; failed)
2818 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2995 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2996 (sizeof(sectNames) changed to sizeof(sectName))
2997 Both patches fix segfaults under MinGW.

3002 Safe_[mc]?alloc()'ed variables
3003 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3004 of (byte sized) temporaries (assign them to WREG for now)
3005 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3006 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3007 this might fix SIGSEGVs on MinGW...
3008 * src/SDCCopt.c (killDeadCode): restored original behaviour
3009 (volatile operands might get thrown away though)
3011 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3013 * src/pic16/gen.c: fixed bug #1106975,

3018 * added function attribute 'shadowregs' to take advantage of shadow
3020 * added function attribute 'wparam' as an alternative to the wparam

3450 Adding support for replacing ljmps with sjmps in jumptables
3451 generated for switch statements. For now you need to set the
3452 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3453 Now 4 algorithms for mcs51 jumptable generation are used:
3454 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3455 addresses loaded pc-relative for up to 112 cases and stack-pushing
3456 target addresses loaded with offset from dptr for up to 256 cases.
3458 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3459 * src/mcs51/main.c: adapted constants for switch table generation
3460 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3480 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3482 Large cummulative patch for pic16 port.
3483 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3484 to call when a stack overflow occurs,
3485 * (malloc.h): added CVS Id tag,
3486 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3488 * added libc directory. The current version of LibC contains string
3489 functions, ctype functions and macros and some functions of the
3490 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3491 be extensively tested in the future. Standard disclaimer here.
3492 Library is not automatically build yet. But one can build it by
3493 invoking 'make' inside the libc directory.
3494 * added ADC library under libio. Preliminary version yet.
3496 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3497 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3498 aopForRemat() now and not by pic16_aopOp(),

3503 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3504 * (pic16_storeForReturn): optimized return of 0,
3505 * (genCmp): experimental code for new genCmp which uses PIC18's
3506 special compare&skip instructions. Initial tests fail some times
3507 with variables grater than 1 byte in size, so new code is disabled,
3508 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3510 * (genCast): began a fix to optimize the casting of a bit to another
3511 bit, now assigning a bitfield to another bitfield will fail, sorry,
3512 * src/pic16/main.c: disabled the use of lr-support feature,
3513 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3514 * added some function prototypes, added function _debugf prototype,
3515 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3516 bits with offset (case PO_GPR_BIT),
3517 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3519 * (isBankInstruction): modified to return 0 for no banking instruction,
3520 and 1 for banking instruction,
3521 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3522 caused stop processing pCodes after a inline assembly block,
3523 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3524 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3525 registers when it shouldn't,
3526 * src/pic16/ralloc.c (allocReg): add preliminary support for
3527 supporting a limited set of temporary registers,
3529 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3531 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3532 genDataPointerSet): ensure assignments always copy in MSB to LSB
3534 (loadRegFromAop): recognize CLRH optimization,
3535 (genFunction): optimize RECEIVE iCodes in reentrant functions
3537 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3539 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3540 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

3551 instead of sjmp to ret
3552 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
3553 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3555 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6537 loaded with the linker search paths (-L arguments) and the libraries
6538 to be linked with the current source (-l arguments). Changes
6539 currently will affect only the pic16 port.
6540 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6541 include path the port specific paths and port specific libraries,

6548 initialization which bypassed the variable initializations block.
6550 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6551 COMPILE_FLAGS and added the --nostdinc option
6553 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6560 Documenting changes from previous commits.
6561 * configure.in (version 1.56),
6562 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6563 when generating output files to configure the pic16 library,
6564 but now I've commented it out, since gputils aren't installed in the
6565 SF compile farm, so library won't compile
6567 * device/lib/Makefile.in (version 1.56): initially I've added in
6568 target 'all' the prerequestive 'model-pic16' so it compiled the
6569 pic16 library, but now I've commented it out for the same reasons
6571 * added targets 'model-pic16' and 'objects-pic16' to compile the
6573 * added target 'port-specific-objects-pic16' to handle the
6574 generated libraries and copy them into the build/ directory
6575 * added target 'clean-intermediate-pic16' to clean intermediate
6576 files into pic16 directory
6577 * in target 'installdirs' added line to create directory pic16 in
6578 the installation path
6580 * device/include/Makefile.in (version 1.11): in target 'install'
6581 added lines to copy all header files to installation path,
6582 * in target 'installdirs' added line create directory for pic16
6583 headers in the installation path
6585 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

6598 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6599 option so that it actually works. Made it specific to the z80, since
6600 the gbz80 doesn't have these kinds of I/O ports.
6602 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6604 * device/include/z180.h,

6610 * device/lib/_strcmp.c,
6611 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
6612 * src/z80/main.c (_process_pragma): add support for pragmas bank and
6613 portmode; added deprecation warning for bank= and protmode= forms.
6614 Also, guard against buffer overflow.

6617 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6619 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6620 changed interrupt vector table generation to only emit declared vectors.
6621 * device/include/Makefile.in: added missing backslash
6622 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
6624 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6626 Mainly changes to support compilation of the device libraries
6627 * src/pic16/device.c: stack is allocated via symbol and not
6628 via literal number. The symbol is placed in the corresponding
6629 position of the data ram
6630 * (pic16_dump_section): relocatable and absolute uninitialized
6631 data are now emitted in sorted order to reduce section naming,
6632 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6633 weren't marked as being in the access bank,
6635 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6637 Added portion of GNU PIC Library under the directory
6638 device/include/pic16 and device/lib/pic16. These files
6639 contain the declarations of SFRs for the PIC18Fxx2 devices.
6640 The directory is initialized via configure from toplevel.
6642 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6644 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6645 the spilllocations to be compared correctly
6647 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6649 * src/SDCCast.c (decorateType): fixed bug introduced today
6651 2004-01-12 Borut Razem <borut.razem AT siol.net>

6669 * doc/sdccman.lyx: Moved and added some sections, small changes
6670 all over. Telling LaTeX to be less strict with word spacing
6671 to better keep the right margin. Changed some notes about
6672 maintainance of the ports in section 3.2.1 - is it OK like this?
6674 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6676 SDCC source changes:
6677 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6711 UPPER for immediate operands,
6712 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6714 * src/pic16/peeph.def: all peepholes with movff are commented out,
6715 because there is a problem in the pcode peep optimizer,
6716 * src/pic16/ralloc.c: the register allocator can now reuse local

6718 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6720 Added file src/pic16/NOTES with information about program writing on
6721 the current port version.

6753 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6756 * src/z80/main.c: added missed needLinkerScript flags (more than
6757 one port structure defined in these file)
6758 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6774 needLinkerScript flag
6776 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6777 * src/pic/glue.c: added variable udata_section_name to
6778 override default uninitialized data segment definition for

6780 * (pic14emitOverlay): modified to emit a commented overlay segment
6781 directive when no overlay data exist
6782 * (picglue): modified to emit uninitialized data segment
6783 according to udata_section_name

6793 2004-01-07 Borut Razem <borut.razem AT siol.net>
6795 * support/scripts/sdcc.nsi: update PATH
6796 * support/scripts/sdcc.ico: craeted

6809 include information about variables allocated to the overlay
6812 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6814 * as/mcs51/lkmain.c: Help about -Y option

6826 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6828 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6829 (default behaviour).
6831 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6833 A python script to validate compiler diagnostic messages. It can be
6834 used to verify that sdcc complains about bad c source code and
6835 gives a good location of the error.
6836 * support/valdiag/Makefile,
6837 * support/valdiag/valdiag.py,
6838 * support/valdiag/tests/*
6840 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6855 Bug reported from Jesus Calvino-Fraga
6857 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6859 * sdcc.spec: updated
6860 * device/include/Makefile.in: don't install CVS directories
6861 * device/lib/Makefile.in: added removal of CVS directories after install
6862 * doc/Makefile: fixed install, added local_icons
6863 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6864 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6865 * src/ds390/gen.c (genRightShift): fixed bug #870788
6866 * src/SDCCast.c (decorateType): fixed bug #870781
6868 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6870 PIC16 port related changes:
6871 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6872 added variable stackPos,
6874 * gen.c: genCall, assignResultValue: added support for
6875 pushing/retrieving function parameters to/from stack,
6876 genFunction,genEndFunction: setup stack frame for the
6878 genAddrOf: will be changed according to bug 863624
6880 * added files genutils.c and genutils.h which contain gen*
6881 debugged and optimised functions extracted from gen.c
6883 * glue.c: added variable 'externs' which holds extern symbols,
6884 pic16emitRegularMap: is modified to properly handle relocatable
6885 symbols under the new scheme,
6886 pic16createInterruptVect: is modified
6887 pic16printPublics: is modified to emit 'global' assembler directives,
6888 added pic16_printExterns to print extern symbols,
6889 pic16glue: initializes stack/frame pointer in the beginning of
6890 the assembly output. Temporary hack, will be corrected later,
6891 because gplink yet does not support stack and SDCC does not
6892 yet support a type of crt0.o object to create the final binary.
6894 * Removed many lines that contain 8051 legacy code.
6895 * The code is finally placed under a 'code' directive.
6896 * Added port specific options.
6898 * _process_pragma: simplified since now we do not need *special*
6899 include file to define SFR registers. But a separate header
6900 will be needed. This will be developed later.
6901 * _pic16_parseOptions: added, parses port specific options:
6902 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6903 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6904 --preplace-udata-with=
6906 * _pic16_setDefaultOptions: modified to initialize section names,
6907 but hack is temporarly out of order since it needs improvement.
6908 * _pic16_genAssemblerPreamble: configuration words are emitted by
6909 their address instead of their name. This part is incomplete and
6910 supports only the 18Fxx2 devices. Other devices will emit an error
6911 during assembly since they do not contain the same set of config
6913 * _pic16_genIVT: is modified,
6915 * pcode.c: added definitions for some hardware registers that are needed
6917 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6918 All PCI entries are updated. Now LFSR is supported.
6919 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6920 * added pic16_newpCodeOpLit2 to support instructions with
6921 two literal arguments
6922 * pic16_pCode2str: corrected code that emits assembler instructions
6923 with two literal operands and those that have an access bit modifier
6924 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6925 this fixes a bug which caused some labels to be lost, when an
6926 assembler directive was added, i.e. banksel,
6927 * pic16_FixRegisterBanking: improved logic that causes the insertion
6929 * InlineFunction: functions that are called once, are not any more
6930 inlined. This can be a port option in the future,
6932 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6934 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6935 hold the corresponding uninitialized symbols,
6936 * pic16_allocProcessorRegister: registers have explicit marked the
6938 * pic16_allocInternalRegister: registers are explicit marked as
6940 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6941 processing list, so bit registers were lost,
6944 * ralloc.h: added field 'accessBank' and original symbol operand
6945 in register definition,
6946 * removed the field isMapped from register definition,
6948 ** Several functions have been removed from various sources:
6949 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6950 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6951 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6952 pic16_assignRelocatableRegisters
6954 ** others have been introduced:
6955 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6956 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6958 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6960 * support/scripts/inc2h.pl: changed definition of BIT_AT
6961 to emit 'sbit at' instead of 'bit at'. This was a request.
6963 PIC16 port related preliminary changes:
6964 * gen.c: prefixed function popRegFromString with
6965 pic16_ and all references to it corrected
6966 * pcode.c: all pic16_pc_* hardware registers prefixed
6967 with underscore (_),
6968 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6969 * ralloc.c: newReg(): when register is REG_SFR then
6970 set address to rIdx,
6971 pic16_allocProcessorRegister(): marks register wasUsed=0
6972 pic16_writeUsedRegs(): added a call to assign processor
6973 registers via pic16_assignFixedRegisters
6975 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6977 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6978 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6979 variables in unused register banks. Also the SSEG is placed
6980 wherever there is enough space for it, and IDATA can be anywhere
6981 in internal RAM. For now compile using -Wl-Y[stack_size].
6982 The mem file is different for this option as well, since it
6983 makes no sense of talking about DSEG lenght.
6985 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6987 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6988 in certain cases, e.g. when ROM assignment, patch provided
6989 from Albert den Haan.
6991 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8034 A few small changes that speed up the peephole optimizer.
8038 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8040 Try to make the peephole optimizer smarter by maintaining
8041 an association between the assembly source code and the
8042 iCodes that originated them. Put this information to use
8043 with a new peephole rule condition "notVolatile" so that
8044 the rules can be aggressive yet still safe.
8049 * src/mcs51/peeph.def
8051 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8055 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8056 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8057 if the left or right operand symbols have the accuse flag set.
8059 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8061 Changed the type of the result of the ! (NOT) operator to char;
8062 previously it returned the same type as the source. This allows
8063 us to eliminate all the genFloatNot functions (all of its target
8064 implementations were very buggy) since !float can use the same
8067 * src/SDCCicode.c (ast2iCode): ! returns char
8068 * src/mcs51/gen.c (genNot, genNotFloat),
8069 * src/ds390/gen.c (genNot, genNotFloat),
8070 * src/z80/gen.c (genNot, genNotFloat),
8071 * src/pic/gen.c (genNot, genNotFloat),
8072 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

8076 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8077 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8078 during interrupts. Ensure WSAVE is located at a shared bank address.
8079 2. Fixed page selection in some places
8080 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8081 the registers name strings.
8082 4. Fixed "signed / unsigned compare" compiler warnings.
8083 5. The PIC port manages its own allocation of the general purpose
8084 registers, but makes no attempt to reuse them. As a result when
8085 compiling it soon runs out of general purpose registers. Some
8086 additional code was added to the files pcode.c and device.c to walk
8087 through the function call tree and rename the registers so that they
8097 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8098 genPlus() & genMinus() when the result is the same as left or right

8104 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8106 Made bitfield a distinct type from bit so that bitfields
8107 convert as per ANSI C and bits retain their traditional
8108 boolean style behaviour. Implemented bitfield support in
8116 * src/ds390/gen.c: bit v bitfield split
8117 * src/z80/gen.c: New support for bitfields
8118 * support/regression/tests/bitfields.c: reenabled z80,
8121 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8123 Rules 246.x, 247.x relate to bitfields, the others speed up
8124 access to xdata mapped I/O devices.
8126 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8128 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8130 Cleaned up genPackBits and genUnpackBits and added two helper
8131 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8132 for literal assignments in genPackBits (thanks to Frieder for
8138 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8140 Fixed bug #748310 (pointer to function type mishandled when the
8141 function name is omitted). Also fixed a SIGSEGV when a function
8142 attribute (reentrant, etc) is used on a non-function or on a
8143 function but misplaced before the parameter list.
8145 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8147 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8170 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8172 Made the constant following the "interrupt" keyword optional. If
8173 omitted, the function will not automatically be given an entry
8174 in the interrupt vector table (similar to #pragma NOIV, but
8175 less syntacticly kludgy). The interrupt number is also now
8176 range checked. Also fixed a bug in the high order bit example

8192 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8194 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8195 be re-activated by defining REDUCE_LITERALS)

8197 unsigned, but are signed by default
8198 * src/SDCCval.c (constVal): rearranged
8199 * src/SDCCval.c (valMod): preliminary fix
8200 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8645 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
8646 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
8647 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
8650 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8652 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8653 the regression tests I'm not brave enough to enable 245.b, 245.c
8654 * doc/sdccman.lyx: added latex preamble for hyperref package.
8655 Using pdflatex this will give you a hyperlinked pdf file with
8656 bookmarks. (prepend '%' before /usepackage if this breaks something)

8668 * src/SDCCglue.c (printIval): fixed bug #739934
8670 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
8672 Applied patch from bug 737905 (renamed yylineo to mylineno):
8679 * src/pic16/pcode.c: Cleaned warnings
8680 * src/pic16/pcodeflow.c: Cleaned warnings
8681 * src/pic16/pcoderegs.c: Cleaned warnings

8694 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8696 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8697 it can be defined with CFLAGS when running configure
8698 * src/SDCCmain.c: fixed compiling + linking with object files
8700 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8702 * configure.in: configure for pic16 port,
8703 added --disable-pic16-port
8704 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8705 * src/SDCCmain.c: linkOptions is changed to set *,
8706 added if/endif conditional macros to remove options help
8707 messages from optionsTable when a port is not configured, added
8708 support for the PIc16 port in the ports table, when executing
8709 the compiler with no port specified on command line, a default
8710 port is selected with the new macro DEFAULT_PORT which is
8711 defined in port.h, in setDefaultOptions() linkOptions is removed
8712 from initialization assignment, since now it is a set,
8713 parseCmdLine uses setParseWithComma for linkOptions, in
8714 linkEdit() linkOptions are accessed with new function indexSet()
8715 which returns the i'th item of a set variable. See SDCCset.c, in
8716 linkEdit() when calling buildCmdLine(), added linkOptions as
8717 last argument. Now users can pass arguments to gplink via the
8718 -Wl option, main() uses pic16glue() to glue up pic16 programs
8719 * src/SDCCpeeph.c: various changes to support pic16
8720 * src/SDCCset.c: added function void *indexSet(set *, int) to

8728 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8730 * src/pic16/glue.c: commented out some error producing lines
8731 * src/pic16/main.c: __config directives are commented out to stop
8732 gpasm complaining and test the linkage with gplink, _linkCmd and
8733 _asmCmd changed to be more gplink and gpasm friendly
8734 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8735 produced an error when parsed, peep rule 12 is added to utilize
8736 movff, but it is commented out since the pCode does not support
8737 yet a command with 2 address arguments
8739 2003-05-18 <johan AT balder>
8741 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8742 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8743 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

8766 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8768 2003-05-11 Borut Razem <borut.razem AT siol.net>
8770 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8771 the path of bin directory, so that PATH is the only env. variable, which has to be set
8772 in case of standard installation.
8773 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9782 2003-01-04 <johan AT balder>
9784 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9786 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9787 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9789 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9790 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9799 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9800 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9802 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9804 * in \sdcc\as\mcs51\ changed these files in order to create an
9805 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9806 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9807 following files to include the previous two files: aslink.dsp,
9808 Makefile.aslink, Makefile.bcc, and Makefile.in.
9810 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9811 .adb instead of .cdb
9813 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9815 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9816 value from option --iram-size.
9818 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9820 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9823 2002-09-18 <wiml AT hhhh.org>
9825 * SDCClrange.h: exposed setFromRange() and setToRange()
9826 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9827 packRegsForAccUse() (bug 542397)
9828 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9829 multiple times and emitting the fetch operations more than once
9830 added aopGetUsesAcc() function to allow binary operators to
9831 fetch their operands in the correct order; made genMinus() emit
9832 compact code for X = LITERAL - Y
9834 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9835 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9836 sprintf() in line 1267.
9838 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9839 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9842 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9843 Changes to aslink (All the changes are marked with 'JCF'):
9845 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9848 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9849 area BSEG. Also moves, if possible, the DATA area down into the internal
9850 ram so more space is available.
9852 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9855 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9856 not bytes. Function summary() which creates a memory usage summary
9857 file with extension .mem. Reports of overlaping stack and small stack
9858 size. If the space for the stack is less than 16 bytes aslink trows a
9861 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9862 the 8051. Option 'y' for memory summary output file.
9864 Changes to sdcc (All the changes are marked with 'JCF'):
9866 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9868 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9869 overlaying area for it (uses RegBankUsed[4]).
9871 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9872 bank zero as used by default. By default aslink locates the stack
9873 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9874 the creation of the .mem file. Delegates the allocation of data area
9875 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9876 the begining of the stack area to aslink.
9878 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9879 glue() in SDCCglue.c creates an area for it.
9881 2002-09-03 Borut Razem <borut.razem AT siol.net>
9882 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9883 sdcc/src/pic/glue.c:
9884 introduced atexit() handler for teporay files removal in case of
9885 errors, assertions, ...
9887 2002-08-29 Borut Razem <borut.razem AT siol.net>
9888 * sdcc/support/cpp2/auto-host_vc_in.h:
9889 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9890 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9891 Maybe there is a similar problem with BORLANDC? It should be checked!
9893 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9894 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9895 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9896 was not executed, and the compiler (cl) launched a warning:
9897 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9899 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9900 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9902 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

9908 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9909 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9910 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9911 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9912 - added Release configuration in VS projects
9913 - review of compiler an linker options
9914 - VC .exe files are generated in bin_vc directory, not to interfere
9915 with binaries generated from other projects (cygwin, mingw, bcc ...)
9917 * sdcc/src/yacc.dsp: added
9919 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9920 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9921 and insert the version number definitions from .version
9923 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9925 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9926 added - genarate auto-host.h using auto-host_vc_in.h as template
9929 removed from CVS, generated automatically
9931 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9932 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9934 2002-08-11 Borut Razem <borut.razem AT siol.net>
9935 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9937 2002-08-10 Borut Razem <borut.razem AT siol.net>
9938 * src/SDCCmain.c (main):
9939 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9940 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9941 The consequence was that some temporary files were not removed.
9944 unification of code in functions tempfilename() and tempfile():
9945 function tempnam() is defined in Visual Studio 6.0 and .NET
9947 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9949 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9950 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9951 - removed compiler command line option /WX: Treats all warnings as errors
9952 - update a list of source files, included into the project
9954 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9968 added newline in the def file to keep MSC compiler satisfied
9970 * sdcc/src/z80/gen.c:
9971 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9972 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9973 - solved MSC error in function aopDump()
9975 * sdcc_vc.h: define PREFIX as "\\sdcc"

10153 Previous fix was not good. basic blocks that have "break" or "return" are
10154 not really partof a loop , but live ranges used in these blocks should
