1768 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1770 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

1772 * src/SDCCglobal.h (struct options),
1774 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1775 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1776 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1777 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1778 always available in leading double underscore form. The C99 support is
1779 mostly missing, but it's a start.
1780 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1781 reserved identifier "__data".
1783 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1829 2005-03-20 Borut Razem <borut.razem AT siol.net>
1831 * support/scripts/inc2h.pl: WIN32 port

1859 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1861 * device/lib/printf_large.c: removed inline assembly for portability and
1862 readability. Use printf_fast if speed or size are more important.
1863 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1864 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1866 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1868 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1869 prevent compiler warning
1871 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1873 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1874 moved to level 0 and declared as static. Also they are explicit
1875 placed in access bank. This was necessery because some times they
1876 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1877 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1878 optimizations. Currently only compare to unsigned char is implemented,
1879 * src/pic16/gen.c: added fReturnIdx array,
1880 * (struct resolvedIfx) is moved to gen.h and made public,
1881 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1882 * (aopForSym): added an optimization to directly store in stack of
1883 the operand of a SEND iCode,
1884 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1885 but as registers instead (AOP_REG) using the fReturnIdx array,
1886 * (pic16_freeAsmop): remove the freed register from the
1887 _G.sregsAlloc field,
1888 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1889 a compare of 'WREG',
1890 * (pic16_popGetTempRegCond): changed function prototype, now
1891 function takes also a bitVector argument v which holds the current
1892 set of registers that are allocated for stack access by aopForSym,
1893 registers allocated in aopForSym for accessing stack symbols are not
1894 any more part of the functions usedRegs field,
1895 * (genCall): some times aopOp is called for a stack variable to be
1896 send, aopForSym might perform the push, if this is true make sure
1897 that genCall doesn't push the variable twice by testing _G.resDirect,
1898 * (genFunction): changed testing for unspecified interrupt number
1899 from 256 to INTNO_UNSPEC,
1900 * modified selection scheme of frame pointer generation. Previously
1901 if function did use local registers a frame pointer was generated,
1902 now a frame pointer is generated only if function has arguments
1903 (that need PLUSW2 register access), or has stack arguments, or the
1904 compiler is not instructed to omit the frame pointer,
1905 * (genEndFunction): before restoring local registers that were saved
1906 in the function preamble, also restore the registers that *might*
1907 have been allocated for stack access,
1908 * (genRet): removed some old comments,
1909 * (genCmp, the active (RN's) version): added a call to the
1910 pic16_genCmp_special function to perform the compare with a more
1911 robust and optimized way,
1912 * (genInline): a feature has been added in inline code generation,
1913 which allows a wildcard variable substitution when writing inline
1914 assembly. Code is incomplete and experimental therefore undocumented,
1915 * (genCast): changed order of aopOp for result and right to allow
1916 aopForSym to directly load the result if possible,
1917 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1918 perform an optimized compare on some selected special occasions,
1919 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1920 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1921 generate an IVT any more,
1922 * src/pic16/main.c (pic16_optionsTable): added command line option
1924 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1925 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1927 * src/pic16/NOTES: Raphael Neider added in list of active developers
1928 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1929 jumptable_end to prevent bug #,
1930 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1931 inCond and outCond fields,
1932 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1933 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1934 turn off register spilling,
1935 * (packRegsForOneUse): synced with other ports' versions although it
1936 is not used currently,
1937 * (pic16_packRegisters): added an optimization while reading
1938 structure bitfields, some registers may be saved (malloc code is
1939 decreased by 80 bytes)
1941 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1943 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1944 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1945 this can be optimized more?
1947 2005-03-10 Raphael Neider <rneider AT web.de>
1949 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1950 genNearPointerGet): (hopefully) fixed access to bitfields via
1951 pointers (p->bitN = x; and x = p->bitN; failed)
1953 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2130 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2131 (sizeof(sectNames) changed to sizeof(sectName))

2139 of (byte sized) temporaries (assign them to WREG for now)
2140 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2141 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2142 this might fix SIGSEGVs on MinGW...
2143 * src/SDCCopt.c (killDeadCode): restored original behaviour
2144 (volatile operands might get thrown away though)
2146 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2587 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2588 Now 4 algorithms for mcs51 jumptable generation are used:
2589 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2590 addresses loaded pc-relative for up to 112 cases and stack-pushing
2591 target addresses loaded with offset from dptr for up to 256 cases.
2593 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2594 * src/mcs51/main.c: adapted constants for switch table generation
2595 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp
2597 2004-11-26 Maarten Brock <sourceforge.brock AT dse.nl>
2599 * device/lib/printf_large.c (_print_format): fixed bug 1073386
2600 * support/regression/tests/bug1057979.c: added test for bug 1073386
2602 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
2604 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
2607 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
2609 * src/pic16/device.h,
2610 * src/pic16/genarith.c,
2613 * src/pic16/pcode.c: applied patches #1068154 and #1070213
2615 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2617 Large cummulative patch for pic16 port.
2618 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2619 to call when a stack overflow occurs,
2620 * (malloc.h): added CVS Id tag,
2621 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2623 * added libc directory. The current version of LibC contains string
2624 functions, ctype functions and macros and some functions of the
2625 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2626 be extensively tested in the future. Standard disclaimer here.
2627 Library is not automatically build yet. But one can build it by
2628 invoking 'make' inside the libc directory.
2629 * added ADC library under libio. Preliminary version yet.
2631 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2632 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2633 aopForRemat() now and not by pic16_aopOp(),
2634 * (pic16_popGetTempReg): removed warning messgae when allocating
2635 temporary registers, its a buggy feature and will be removed,
2636 * (pic16_popGet): set register instance field in AOP_CRY,
2637 * (pic16_outBitC): fixed for results in size greater than 1,
2638 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2639 * (pic16_storeForReturn): optimized return of 0,
2640 * (genCmp): experimental code for new genCmp which uses PIC18's
2641 special compare&skip instructions. Initial tests fail some times
2642 with variables grater than 1 byte in size, so new code is disabled,
2643 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2645 * (genCast): began a fix to optimize the casting of a bit to another
2646 bit, now assigning a bitfield to another bitfield will fail, sorry,
2647 * src/pic16/main.c: disabled the use of lr-support feature,
2648 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2649 * added some function prototypes, added function _debugf prototype,
2650 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2651 bits with offset (case PO_GPR_BIT),
2652 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2654 * (isBankInstruction): modified to return 0 for no banking instruction,
2655 and 1 for banking instruction,
2656 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2657 caused stop processing pCodes after a inline assembly block,
2658 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2659 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2660 registers when it shouldn't,
2661 * src/pic16/ralloc.c (allocReg): add preliminary support for
2662 supporting a limited set of temporary registers,
2664 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2666 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2667 genDataPointerSet): ensure assignments always copy in MSB to LSB
2669 (loadRegFromAop): recognize CLRH optimization,
2670 (genFunction): optimize RECEIVE iCodes in reentrant functions
2672 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2674 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2675 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2677 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2685 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2686 instead of sjmp to ret
2687 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2688 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2690 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5672 loaded with the linker search paths (-L arguments) and the libraries
5673 to be linked with the current source (-l arguments). Changes
5674 currently will affect only the pic16 port.
5675 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5676 include path the port specific paths and port specific libraries,

5693 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5695 Documenting changes from previous commits.
5696 * configure.in (version 1.56),
5697 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5698 when generating output files to configure the pic16 library,
5699 but now I've commented it out, since gputils aren't installed in the
5700 SF compile farm, so library won't compile
5702 * device/lib/Makefile.in (version 1.56): initially I've added in
5703 target 'all' the prerequestive 'model-pic16' so it compiled the
5704 pic16 library, but now I've commented it out for the same reasons
5706 * added targets 'model-pic16' and 'objects-pic16' to compile the
5708 * added target 'port-specific-objects-pic16' to handle the
5709 generated libraries and copy them into the build/ directory
5710 * added target 'clean-intermediate-pic16' to clean intermediate
5711 files into pic16 directory
5712 * in target 'installdirs' added line to create directory pic16 in
5713 the installation path
5715 * device/include/Makefile.in (version 1.11): in target 'install'
5716 added lines to copy all header files to installation path,
5717 * in target 'installdirs' added line create directory for pic16
5718 headers in the installation path
5720 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5733 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5734 option so that it actually works. Made it specific to the z80, since
5735 the gbz80 doesn't have these kinds of I/O ports.
5737 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5739 * device/include/z180.h,

5745 * device/lib/_strcmp.c,
5746 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5747 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5748 portmode; added deprecation warning for bank= and protmode= forms.
5749 Also, guard against buffer overflow.
5750 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5752 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5754 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5755 changed interrupt vector table generation to only emit declared vectors.
5756 * device/include/Makefile.in: added missing backslash
5757 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5761 Mainly changes to support compilation of the device libraries
5762 * src/pic16/device.c: stack is allocated via symbol and not
5763 via literal number. The symbol is placed in the corresponding
5764 position of the data ram
5765 * (pic16_dump_section): relocatable and absolute uninitialized
5766 data are now emitted in sorted order to reduce section naming,
5767 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5768 weren't marked as being in the access bank,
5770 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5772 Added portion of GNU PIC Library under the directory
5773 device/include/pic16 and device/lib/pic16. These files
5774 contain the declarations of SFRs for the PIC18Fxx2 devices.
5775 The directory is initialized via configure from toplevel.
5777 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5779 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5780 the spilllocations to be compared correctly

5804 * doc/sdccman.lyx: Moved and added some sections, small changes
5805 all over. Telling LaTeX to be less strict with word spacing
5806 to better keep the right margin. Changed some notes about
5807 maintainance of the ports in section 3.2.1 - is it OK like this?
5809 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5846 UPPER for immediate operands,
5847 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5849 * src/pic16/peeph.def: all peepholes with movff are commented out,
5850 because there is a problem in the pcode peep optimizer,
5851 * src/pic16/ralloc.c: the register allocator can now reuse local
5852 function symbols for another function. This saves register usage.
5853 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5855 Added file src/pic16/NOTES with information about program writing on
5856 the current port version.

5888 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5891 * src/z80/main.c: added missed needLinkerScript flags (more than
5892 one port structure defined in these file)
5893 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5909 needLinkerScript flag
5911 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5912 * src/pic/glue.c: added variable udata_section_name to
5913 override default uninitialized data segment definition for
5914 devices only with SHAREBANK memory (reported from Erik Epetrich)
5915 * (pic14emitOverlay): modified to emit a commented overlay segment
5916 directive when no overlay data exist
5917 * (picglue): modified to emit uninitialized data segment
5918 according to udata_section_name

5928 2004-01-07 Borut Razem <borut.razem AT siol.net>
5930 * support/scripts/sdcc.nsi: update PATH
5931 * support/scripts/sdcc.ico: craeted

5944 include information about variables allocated to the overlay
5947 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5949 * as/mcs51/lkmain.c: Help about -Y option

5961 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5963 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5964 (default behaviour).
5966 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5968 A python script to validate compiler diagnostic messages. It can be
5969 used to verify that sdcc complains about bad c source code and
5970 gives a good location of the error.
5971 * support/valdiag/Makefile,
5972 * support/valdiag/valdiag.py,
5973 * support/valdiag/tests/*
5975 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5990 Bug reported from Jesus Calvino-Fraga
5992 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5994 * sdcc.spec: updated
5995 * device/include/Makefile.in: don't install CVS directories
5996 * device/lib/Makefile.in: added removal of CVS directories after install
5997 * doc/Makefile: fixed install, added local_icons
5998 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5999 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6000 * src/ds390/gen.c (genRightShift): fixed bug #870788
6001 * src/SDCCast.c (decorateType): fixed bug #870781
6003 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6005 PIC16 port related changes:
6006 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6007 added variable stackPos,
6009 * gen.c: genCall, assignResultValue: added support for
6010 pushing/retrieving function parameters to/from stack,
6011 genFunction,genEndFunction: setup stack frame for the
6013 genAddrOf: will be changed according to bug 863624
6015 * added files genutils.c and genutils.h which contain gen*
6016 debugged and optimised functions extracted from gen.c
6018 * glue.c: added variable 'externs' which holds extern symbols,
6019 pic16emitRegularMap: is modified to properly handle relocatable
6020 symbols under the new scheme,
6021 pic16createInterruptVect: is modified
6022 pic16printPublics: is modified to emit 'global' assembler directives,
6023 added pic16_printExterns to print extern symbols,
6024 pic16glue: initializes stack/frame pointer in the beginning of
6025 the assembly output. Temporary hack, will be corrected later,
6026 because gplink yet does not support stack and SDCC does not
6027 yet support a type of crt0.o object to create the final binary.
6029 * Removed many lines that contain 8051 legacy code.
6030 * The code is finally placed under a 'code' directive.
6031 * Added port specific options.
6033 * _process_pragma: simplified since now we do not need *special*
6034 include file to define SFR registers. But a separate header
6035 will be needed. This will be developed later.
6036 * _pic16_parseOptions: added, parses port specific options:
6037 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6038 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6039 --preplace-udata-with=
6041 * _pic16_setDefaultOptions: modified to initialize section names,
6042 but hack is temporarly out of order since it needs improvement.
6043 * _pic16_genAssemblerPreamble: configuration words are emitted by
6044 their address instead of their name. This part is incomplete and
6045 supports only the 18Fxx2 devices. Other devices will emit an error
6046 during assembly since they do not contain the same set of config
6048 * _pic16_genIVT: is modified,
6050 * pcode.c: added definitions for some hardware registers that are needed
6052 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6053 All PCI entries are updated. Now LFSR is supported.
6054 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6055 * added pic16_newpCodeOpLit2 to support instructions with
6056 two literal arguments
6057 * pic16_pCode2str: corrected code that emits assembler instructions
6058 with two literal operands and those that have an access bit modifier
6059 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6060 this fixes a bug which caused some labels to be lost, when an
6061 assembler directive was added, i.e. banksel,
6062 * pic16_FixRegisterBanking: improved logic that causes the insertion
6064 * InlineFunction: functions that are called once, are not any more
6065 inlined. This can be a port option in the future,
6067 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6069 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6070 hold the corresponding uninitialized symbols,
6071 * pic16_allocProcessorRegister: registers have explicit marked the
6073 * pic16_allocInternalRegister: registers are explicit marked as
6075 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6076 processing list, so bit registers were lost,
6079 * ralloc.h: added field 'accessBank' and original symbol operand
6080 in register definition,
6081 * removed the field isMapped from register definition,
6083 ** Several functions have been removed from various sources:
6084 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6085 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6086 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6087 pic16_assignRelocatableRegisters
6089 ** others have been introduced:
6090 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6091 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6093 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6095 * support/scripts/inc2h.pl: changed definition of BIT_AT
6096 to emit 'sbit at' instead of 'bit at'. This was a request.
6098 PIC16 port related preliminary changes:
6099 * gen.c: prefixed function popRegFromString with
6100 pic16_ and all references to it corrected
6101 * pcode.c: all pic16_pc_* hardware registers prefixed
6102 with underscore (_),
6103 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6104 * ralloc.c: newReg(): when register is REG_SFR then
6105 set address to rIdx,
6106 pic16_allocProcessorRegister(): marks register wasUsed=0
6107 pic16_writeUsedRegs(): added a call to assign processor
6108 registers via pic16_assignFixedRegisters
6110 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6112 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6113 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6114 variables in unused register banks. Also the SSEG is placed
6115 wherever there is enough space for it, and IDATA can be anywhere
6116 in internal RAM. For now compile using -Wl-Y[stack_size].
6117 The mem file is different for this option as well, since it
6118 makes no sense of talking about DSEG lenght.
6120 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6122 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6123 in certain cases, e.g. when ROM assignment, patch provided
6124 from Albert den Haan.
6126 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7177 iCodes that originated them. Put this information to use
7178 with a new peephole rule condition "notVolatile" so that
7179 the rules can be aggressive yet still safe.
7184 * src/mcs51/peeph.def
7186 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7190 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7191 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7192 if the left or right operand symbols have the accuse flag set.
7194 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7196 Changed the type of the result of the ! (NOT) operator to char;
7197 previously it returned the same type as the source. This allows
7198 us to eliminate all the genFloatNot functions (all of its target
7199 implementations were very buggy) since !float can use the same
7202 * src/SDCCicode.c (ast2iCode): ! returns char

7211 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7212 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7213 during interrupts. Ensure WSAVE is located at a shared bank address.
7214 2. Fixed page selection in some places
7215 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7216 the registers name strings.
7217 4. Fixed "signed / unsigned compare" compiler warnings.
7218 5. The PIC port manages its own allocation of the general purpose
7219 registers, but makes no attempt to reuse them. As a result when
7220 compiling it soon runs out of general purpose registers. Some
7221 additional code was added to the files pcode.c and device.c to walk
7222 through the function call tree and rename the registers so that they
7232 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7233 genPlus() & genMinus() when the result is the same as left or right

7239 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7241 Made bitfield a distinct type from bit so that bitfields
7242 convert as per ANSI C and bits retain their traditional
7243 boolean style behaviour. Implemented bitfield support in
7251 * src/ds390/gen.c: bit v bitfield split
7252 * src/z80/gen.c: New support for bitfields
7253 * support/regression/tests/bitfields.c: reenabled z80,
7256 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7258 Rules 246.x, 247.x relate to bitfields, the others speed up
7259 access to xdata mapped I/O devices.
7261 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7263 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7265 Cleaned up genPackBits and genUnpackBits and added two helper
7266 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7267 for literal assignments in genPackBits (thanks to Frieder for
7273 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7275 Fixed bug #748310 (pointer to function type mishandled when the
7276 function name is omitted). Also fixed a SIGSEGV when a function
7277 attribute (reentrant, etc) is used on a non-function or on a
7278 function but misplaced before the parameter list.
7280 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7282 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7305 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7307 Made the constant following the "interrupt" keyword optional. If
7308 omitted, the function will not automatically be given an entry
7309 in the interrupt vector table (similar to #pragma NOIV, but
7310 less syntacticly kludgy). The interrupt number is also now
7311 range checked. Also fixed a bug in the high order bit example

7332 unsigned, but are signed by default
7333 * src/SDCCval.c (constVal): rearranged
7334 * src/SDCCval.c (valMod): preliminary fix
7335 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7771 * device/lib/gbz80/mul.s
7772 * device/lib/gbz80/stubs.s
7773 * device/lib/z80/mul.s
7774 * device/lib/z80/stubs.s
7775 * src/SDCCsymt.c (initCSupport)
7777 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7779 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
7780 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7781 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7782 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7785 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7787 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7788 the regression tests I'm not brave enough to enable 245.b, 245.c
7789 * doc/sdccman.lyx: added latex preamble for hyperref package.
7790 Using pdflatex this will give you a hyperlinked pdf file with
7791 bookmarks. (prepend '%' before /usepackage if this breaks something)
7793 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7803 * src/SDCCglue.c (printIval): fixed bug #739934
7805 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
7807 Applied patch from bug 737905 (renamed yylineo to mylineno):
7814 * src/pic16/pcode.c: Cleaned warnings
7815 * src/pic16/pcodeflow.c: Cleaned warnings
7816 * src/pic16/pcoderegs.c: Cleaned warnings
7818 2003-05-19 Scott Dattalo <scott AT dattalo.com>

7827 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7829 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7831 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7832 it can be defined with CFLAGS when running configure
7833 * src/SDCCmain.c: fixed compiling + linking with object files
7835 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7837 * configure.in: configure for pic16 port,
7838 added --disable-pic16-port
7839 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7840 * src/SDCCmain.c: linkOptions is changed to set *,
7841 added if/endif conditional macros to remove options help
7842 messages from optionsTable when a port is not configured, added
7843 support for the PIc16 port in the ports table, when executing
7844 the compiler with no port specified on command line, a default
7845 port is selected with the new macro DEFAULT_PORT which is
7846 defined in port.h, in setDefaultOptions() linkOptions is removed
7847 from initialization assignment, since now it is a set,
7848 parseCmdLine uses setParseWithComma for linkOptions, in
7849 linkEdit() linkOptions are accessed with new function indexSet()
7850 which returns the i'th item of a set variable. See SDCCset.c, in
7851 linkEdit() when calling buildCmdLine(), added linkOptions as
7852 last argument. Now users can pass arguments to gplink via the
7853 -Wl option, main() uses pic16glue() to glue up pic16 programs
7854 * src/SDCCpeeph.c: various changes to support pic16
7855 * src/SDCCset.c: added function void *indexSet(set *, int) to

7863 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7865 * src/pic16/glue.c: commented out some error producing lines
7866 * src/pic16/main.c: __config directives are commented out to stop
7867 gpasm complaining and test the linkage with gplink, _linkCmd and
7868 _asmCmd changed to be more gplink and gpasm friendly
7869 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7870 produced an error when parsed, peep rule 12 is added to utilize
7871 movff, but it is commented out since the pCode does not support
7872 yet a command with 2 address arguments
7874 2003-05-18 <johan AT balder>
7876 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7877 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7901 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7903 2003-05-11 Borut Razem <borut.razem AT siol.net>
7905 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7906 the path of bin directory, so that PATH is the only env. variable, which has to be set
7907 in case of standard installation.
7908 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8911 * src/SDCCicode.c: fixed array add
8913 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8914 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8915 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8917 2003-01-04 <johan AT balder>
8919 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8921 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8922 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8924 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8932 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8934 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8935 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8937 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8939 * in \sdcc\as\mcs51\ changed these files in order to create an
8940 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8941 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8942 following files to include the previous two files: aslink.dsp,
8943 Makefile.aslink, Makefile.bcc, and Makefile.in.
8945 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8946 .adb instead of .cdb
8948 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8950 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8951 value from option --iram-size.
8953 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8955 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8958 2002-09-18 <wiml AT hhhh.org>
8960 * SDCClrange.h: exposed setFromRange() and setToRange()
8961 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8962 packRegsForAccUse() (bug 542397)
8963 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8964 multiple times and emitting the fetch operations more than once
8965 added aopGetUsesAcc() function to allow binary operators to
8966 fetch their operands in the correct order; made genMinus() emit
8967 compact code for X = LITERAL - Y
8969 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8970 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8971 sprintf() in line 1267.
8973 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8974 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8977 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8978 Changes to aslink (All the changes are marked with 'JCF'):
8980 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8983 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8984 area BSEG. Also moves, if possible, the DATA area down into the internal
8985 ram so more space is available.
8987 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8990 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8991 not bytes. Function summary() which creates a memory usage summary
8992 file with extension .mem. Reports of overlaping stack and small stack
8993 size. If the space for the stack is less than 16 bytes aslink trows a
8996 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8997 the 8051. Option 'y' for memory summary output file.
8999 Changes to sdcc (All the changes are marked with 'JCF'):
9001 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9003 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9004 overlaying area for it (uses RegBankUsed[4]).
9006 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9007 bank zero as used by default. By default aslink locates the stack
9008 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9009 the creation of the .mem file. Delegates the allocation of data area
9010 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9011 the begining of the stack area to aslink.
9013 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9014 glue() in SDCCglue.c creates an area for it.
9016 2002-09-03 Borut Razem <borut.razem AT siol.net>
9017 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9018 sdcc/src/pic/glue.c:
9019 introduced atexit() handler for teporay files removal in case of
9020 errors, assertions, ...
9022 2002-08-29 Borut Razem <borut.razem AT siol.net>
9023 * sdcc/support/cpp2/auto-host_vc_in.h:
9024 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9025 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9026 Maybe there is a similar problem with BORLANDC? It should be checked!
9028 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9029 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9030 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9031 was not executed, and the compiler (cl) launched a warning:
9032 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9034 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9035 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9037 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9038 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9040 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9041 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9042 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9043 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9044 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9045 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9046 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9047 - added Release configuration in VS projects
9048 - review of compiler an linker options
9049 - VC .exe files are generated in bin_vc directory, not to interfere
9050 with binaries generated from other projects (cygwin, mingw, bcc ...)
9052 * sdcc/src/yacc.dsp: added
9054 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9055 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9056 and insert the version number definitions from .version
9058 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9060 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9061 added - genarate auto-host.h using auto-host_vc_in.h as template
9064 removed from CVS, generated automatically
9066 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9067 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9069 2002-08-11 Borut Razem <borut.razem AT siol.net>
9070 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9072 2002-08-10 Borut Razem <borut.razem AT siol.net>
9073 * src/SDCCmain.c (main):
9074 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9075 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9076 The consequence was that some temporary files were not removed.
9079 unification of code in functions tempfilename() and tempfile():
9080 function tempnam() is defined in Visual Studio 6.0 and .NET

9288 Previous fix was not good. basic blocks that have "break" or "return" are
9289 not really partof a loop , but live ranges used in these blocks should
