1784 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1786 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

1790 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1791 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1792 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1793 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1794 always available in leading double underscore form. The C99 support is
1795 mostly missing, but it's a start.
1796 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1797 reserved identifier "__data".
1799 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1843 immedDom() returning wrong block; probably fixes bug #1160833)
1845 2005-03-20 Borut Razem <borut.razem AT siol.net>
1847 * support/scripts/inc2h.pl: WIN32 port

1875 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1877 * device/lib/printf_large.c: removed inline assembly for portability and
1878 readability. Use printf_fast if speed or size are more important.
1879 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1880 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1882 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1884 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1885 prevent compiler warning
1887 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1889 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1890 moved to level 0 and declared as static. Also they are explicit
1891 placed in access bank. This was necessery because some times they
1892 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1893 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1894 optimizations. Currently only compare to unsigned char is implemented,
1895 * src/pic16/gen.c: added fReturnIdx array,
1896 * (struct resolvedIfx) is moved to gen.h and made public,
1897 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1898 * (aopForSym): added an optimization to directly store in stack of
1899 the operand of a SEND iCode,
1900 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1901 but as registers instead (AOP_REG) using the fReturnIdx array,
1902 * (pic16_freeAsmop): remove the freed register from the
1903 _G.sregsAlloc field,
1904 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1905 a compare of 'WREG',
1906 * (pic16_popGetTempRegCond): changed function prototype, now
1907 function takes also a bitVector argument v which holds the current
1908 set of registers that are allocated for stack access by aopForSym,
1909 registers allocated in aopForSym for accessing stack symbols are not
1910 any more part of the functions usedRegs field,
1911 * (genCall): some times aopOp is called for a stack variable to be
1912 send, aopForSym might perform the push, if this is true make sure
1913 that genCall doesn't push the variable twice by testing _G.resDirect,
1914 * (genFunction): changed testing for unspecified interrupt number
1915 from 256 to INTNO_UNSPEC,
1916 * modified selection scheme of frame pointer generation. Previously
1917 if function did use local registers a frame pointer was generated,
1918 now a frame pointer is generated only if function has arguments
1919 (that need PLUSW2 register access), or has stack arguments, or the
1920 compiler is not instructed to omit the frame pointer,
1921 * (genEndFunction): before restoring local registers that were saved
1922 in the function preamble, also restore the registers that *might*
1923 have been allocated for stack access,
1924 * (genRet): removed some old comments,
1925 * (genCmp, the active (RN's) version): added a call to the
1926 pic16_genCmp_special function to perform the compare with a more
1927 robust and optimized way,
1928 * (genInline): a feature has been added in inline code generation,
1929 which allows a wildcard variable substitution when writing inline
1930 assembly. Code is incomplete and experimental therefore undocumented,
1931 * (genCast): changed order of aopOp for result and right to allow
1932 aopForSym to directly load the result if possible,
1933 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1934 perform an optimized compare on some selected special occasions,
1935 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1936 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1937 generate an IVT any more,
1938 * src/pic16/main.c (pic16_optionsTable): added command line option
1940 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1941 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1943 * src/pic16/NOTES: Raphael Neider added in list of active developers
1944 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1945 jumptable_end to prevent bug #,
1946 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1947 inCond and outCond fields,
1948 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1949 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1950 turn off register spilling,
1951 * (packRegsForOneUse): synced with other ports' versions although it
1952 is not used currently,
1953 * (pic16_packRegisters): added an optimization while reading
1954 structure bitfields, some registers may be saved (malloc code is
1955 decreased by 80 bytes)
1957 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1959 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1960 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1961 this can be optimized more?
1963 2005-03-10 Raphael Neider <rneider AT web.de>
1965 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1966 genNearPointerGet): (hopefully) fixed access to bitfields via
1967 pointers (p->bitN = x; and x = p->bitN; failed)
1969 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2146 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2147 (sizeof(sectNames) changed to sizeof(sectName))

2155 of (byte sized) temporaries (assign them to WREG for now)
2156 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2157 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2158 this might fix SIGSEGVs on MinGW...
2159 * src/SDCCopt.c (killDeadCode): restored original behaviour
2160 (volatile operands might get thrown away though)

2588 comparisons, and supports quoted literals
2589 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
2591 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2599 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2601 Adding support for replacing ljmps with sjmps in jumptables
2602 generated for switch statements. For now you need to set the
2603 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2604 Now 4 algorithms for mcs51 jumptable generation are used:
2605 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2606 addresses loaded pc-relative for up to 112 cases and stack-pushing
2607 target addresses loaded with offset from dptr for up to 256 cases.
2609 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2610 * src/mcs51/main.c: adapted constants for switch table generation
2611 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2631 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2633 Large cummulative patch for pic16 port.
2634 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2635 to call when a stack overflow occurs,
2636 * (malloc.h): added CVS Id tag,
2637 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2639 * added libc directory. The current version of LibC contains string
2640 functions, ctype functions and macros and some functions of the
2641 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2642 be extensively tested in the future. Standard disclaimer here.
2643 Library is not automatically build yet. But one can build it by
2644 invoking 'make' inside the libc directory.
2645 * added ADC library under libio. Preliminary version yet.
2647 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2648 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2649 aopForRemat() now and not by pic16_aopOp(),
2650 * (pic16_popGetTempReg): removed warning messgae when allocating
2651 temporary registers, its a buggy feature and will be removed,
2652 * (pic16_popGet): set register instance field in AOP_CRY,
2653 * (pic16_outBitC): fixed for results in size greater than 1,
2654 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2655 * (pic16_storeForReturn): optimized return of 0,
2656 * (genCmp): experimental code for new genCmp which uses PIC18's
2657 special compare&skip instructions. Initial tests fail some times
2658 with variables grater than 1 byte in size, so new code is disabled,
2659 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2661 * (genCast): began a fix to optimize the casting of a bit to another
2662 bit, now assigning a bitfield to another bitfield will fail, sorry,
2663 * src/pic16/main.c: disabled the use of lr-support feature,
2664 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2665 * added some function prototypes, added function _debugf prototype,
2666 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2667 bits with offset (case PO_GPR_BIT),
2668 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2670 * (isBankInstruction): modified to return 0 for no banking instruction,
2671 and 1 for banking instruction,
2672 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2673 caused stop processing pCodes after a inline assembly block,
2674 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2675 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2676 registers when it shouldn't,
2677 * src/pic16/ralloc.c (allocReg): add preliminary support for
2678 supporting a limited set of temporary registers,
2680 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2682 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2683 genDataPointerSet): ensure assignments always copy in MSB to LSB
2685 (loadRegFromAop): recognize CLRH optimization,
2686 (genFunction): optimize RECEIVE iCodes in reentrant functions
2688 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2690 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2691 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2693 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2699 * device/lib/_gptrget.c (_gptrget),
2700 * device/lib/_gptrgetc.c (_gptrgetc),
2701 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2702 instead of sjmp to ret
2703 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2704 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2706 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5688 loaded with the linker search paths (-L arguments) and the libraries
5689 to be linked with the current source (-l arguments). Changes
5690 currently will affect only the pic16 port.
5691 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5692 include path the port specific paths and port specific libraries,
5693 * gplink command now contains the $3 argument,
5694 * src/pic16/device.h,
5695 * src/pic16/device.c,: structure PIC_device is made public and
5696 renamed to PIC16_device, the same for variable Pics which is renamed
5697 to Pics16. Updated all references to them.
5698 * src/pic16/glue.c (pic16glue): corrected bug with code
5699 initialization which bypassed the variable initializations block.
5701 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5702 COMPILE_FLAGS and added the --nostdinc option
5704 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5706 * device/include/mc68hc908jb8.h: Register defs for another member
5707 of the hc08 family. Contributed by Bjorn Bringert - thanks!

5711 Documenting changes from previous commits.
5712 * configure.in (version 1.56),
5713 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5714 when generating output files to configure the pic16 library,
5715 but now I've commented it out, since gputils aren't installed in the
5716 SF compile farm, so library won't compile
5718 * device/lib/Makefile.in (version 1.56): initially I've added in
5719 target 'all' the prerequestive 'model-pic16' so it compiled the
5720 pic16 library, but now I've commented it out for the same reasons
5722 * added targets 'model-pic16' and 'objects-pic16' to compile the
5724 * added target 'port-specific-objects-pic16' to handle the
5725 generated libraries and copy them into the build/ directory
5726 * added target 'clean-intermediate-pic16' to clean intermediate
5727 files into pic16 directory
5728 * in target 'installdirs' added line to create directory pic16 in
5729 the installation path
5731 * device/include/Makefile.in (version 1.11): in target 'install'
5732 added lines to copy all header files to installation path,
5733 * in target 'installdirs' added line create directory for pic16
5734 headers in the installation path

5749 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5750 option so that it actually works. Made it specific to the z80, since
5751 the gbz80 doesn't have these kinds of I/O ports.
5753 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5755 * device/include/z180.h,

5768 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5770 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5771 changed interrupt vector table generation to only emit declared vectors.
5772 * device/include/Makefile.in: added missing backslash
5773 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5777 Mainly changes to support compilation of the device libraries
5778 * src/pic16/device.c: stack is allocated via symbol and not
5779 via literal number. The symbol is placed in the corresponding
5780 position of the data ram
5781 * (pic16_dump_section): relocatable and absolute uninitialized
5782 data are now emitted in sorted order to reduce section naming,
5783 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5784 weren't marked as being in the access bank,
5786 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5788 Added portion of GNU PIC Library under the directory
5789 device/include/pic16 and device/lib/pic16. These files
5790 contain the declarations of SFRs for the PIC18Fxx2 devices.
5791 The directory is initialized via configure from toplevel.
5793 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5795 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5796 the spilllocations to be compared correctly
5798 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5800 * src/SDCCast.c (decorateType): fixed bug introduced today
5802 2004-01-12 Borut Razem <borut.razem AT siol.net>

5820 * doc/sdccman.lyx: Moved and added some sections, small changes
5821 all over. Telling LaTeX to be less strict with word spacing
5822 to better keep the right margin. Changed some notes about
5823 maintainance of the ports in section 3.2.1 - is it OK like this?
5825 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5862 UPPER for immediate operands,
5863 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5865 * src/pic16/peeph.def: all peepholes with movff are commented out,
5866 because there is a problem in the pcode peep optimizer,
5867 * src/pic16/ralloc.c: the register allocator can now reuse local

5869 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5871 Added file src/pic16/NOTES with information about program writing on
5872 the current port version.

5881 * src/SDCCmain.c : fixed #872250: -l command line defined library
5882 files are scanned before standard library files
5884 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5904 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5907 * src/z80/main.c: added missed needLinkerScript flags (more than
5908 one port structure defined in these file)
5909 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5925 needLinkerScript flag
5927 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5928 * src/pic/glue.c: added variable udata_section_name to
5929 override default uninitialized data segment definition for

5931 * (pic14emitOverlay): modified to emit a commented overlay segment
5932 directive when no overlay data exist
5933 * (picglue): modified to emit uninitialized data segment
5934 according to udata_section_name

5944 2004-01-07 Borut Razem <borut.razem AT siol.net>
5946 * support/scripts/sdcc.nsi: update PATH
5947 * support/scripts/sdcc.ico: craeted

5960 include information about variables allocated to the overlay
5963 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5965 * as/mcs51/lkmain.c: Help about -Y option

5977 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5979 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5980 (default behaviour).
5982 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5984 A python script to validate compiler diagnostic messages. It can be
5985 used to verify that sdcc complains about bad c source code and
5986 gives a good location of the error.
5987 * support/valdiag/Makefile,
5988 * support/valdiag/valdiag.py,
5989 * support/valdiag/tests/*
5991 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6004 * src/common.h: added ifndef/define/endif macros
6005 around the header file.
6006 Bug reported from Jesus Calvino-Fraga
6008 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6010 * sdcc.spec: updated
6011 * device/include/Makefile.in: don't install CVS directories
6012 * device/lib/Makefile.in: added removal of CVS directories after install
6013 * doc/Makefile: fixed install, added local_icons
6014 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6015 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6016 * src/ds390/gen.c (genRightShift): fixed bug #870788
6017 * src/SDCCast.c (decorateType): fixed bug #870781
6019 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6021 PIC16 port related changes:
6022 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6023 added variable stackPos,
6025 * gen.c: genCall, assignResultValue: added support for
6026 pushing/retrieving function parameters to/from stack,
6027 genFunction,genEndFunction: setup stack frame for the
6029 genAddrOf: will be changed according to bug 863624
6031 * added files genutils.c and genutils.h which contain gen*
6032 debugged and optimised functions extracted from gen.c
6034 * glue.c: added variable 'externs' which holds extern symbols,
6035 pic16emitRegularMap: is modified to properly handle relocatable
6036 symbols under the new scheme,
6037 pic16createInterruptVect: is modified
6038 pic16printPublics: is modified to emit 'global' assembler directives,
6039 added pic16_printExterns to print extern symbols,
6040 pic16glue: initializes stack/frame pointer in the beginning of
6041 the assembly output. Temporary hack, will be corrected later,
6042 because gplink yet does not support stack and SDCC does not
6043 yet support a type of crt0.o object to create the final binary.
6045 * Removed many lines that contain 8051 legacy code.
6046 * The code is finally placed under a 'code' directive.
6047 * Added port specific options.
6049 * _process_pragma: simplified since now we do not need *special*
6050 include file to define SFR registers. But a separate header
6051 will be needed. This will be developed later.
6052 * _pic16_parseOptions: added, parses port specific options:
6053 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6054 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6055 --preplace-udata-with=
6057 * _pic16_setDefaultOptions: modified to initialize section names,
6058 but hack is temporarly out of order since it needs improvement.
6059 * _pic16_genAssemblerPreamble: configuration words are emitted by
6060 their address instead of their name. This part is incomplete and
6061 supports only the 18Fxx2 devices. Other devices will emit an error
6062 during assembly since they do not contain the same set of config
6064 * _pic16_genIVT: is modified,
6066 * pcode.c: added definitions for some hardware registers that are needed
6068 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6069 All PCI entries are updated. Now LFSR is supported.
6070 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6071 * added pic16_newpCodeOpLit2 to support instructions with
6072 two literal arguments
6073 * pic16_pCode2str: corrected code that emits assembler instructions
6074 with two literal operands and those that have an access bit modifier
6075 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6076 this fixes a bug which caused some labels to be lost, when an
6077 assembler directive was added, i.e. banksel,
6078 * pic16_FixRegisterBanking: improved logic that causes the insertion
6080 * InlineFunction: functions that are called once, are not any more
6081 inlined. This can be a port option in the future,
6083 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6085 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6086 hold the corresponding uninitialized symbols,
6087 * pic16_allocProcessorRegister: registers have explicit marked the
6089 * pic16_allocInternalRegister: registers are explicit marked as
6091 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6092 processing list, so bit registers were lost,
6095 * ralloc.h: added field 'accessBank' and original symbol operand
6096 in register definition,
6097 * removed the field isMapped from register definition,
6099 ** Several functions have been removed from various sources:
6100 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6101 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6102 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6103 pic16_assignRelocatableRegisters
6105 ** others have been introduced:
6106 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6107 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6109 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6111 * support/scripts/inc2h.pl: changed definition of BIT_AT
6112 to emit 'sbit at' instead of 'bit at'. This was a request.
6114 PIC16 port related preliminary changes:
6115 * gen.c: prefixed function popRegFromString with
6116 pic16_ and all references to it corrected
6117 * pcode.c: all pic16_pc_* hardware registers prefixed
6118 with underscore (_),
6119 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6120 * ralloc.c: newReg(): when register is REG_SFR then
6121 set address to rIdx,
6122 pic16_allocProcessorRegister(): marks register wasUsed=0
6123 pic16_writeUsedRegs(): added a call to assign processor
6124 registers via pic16_assignFixedRegisters
6126 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6128 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6129 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6130 variables in unused register banks. Also the SSEG is placed
6131 wherever there is enough space for it, and IDATA can be anywhere
6132 in internal RAM. For now compile using -Wl-Y[stack_size].
6133 The mem file is different for this option as well, since it
6134 makes no sense of talking about DSEG lenght.
6136 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6138 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6139 in certain cases, e.g. when ROM assignment, patch provided
6140 from Albert den Haan.
6142 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7185 A few small changes that speed up the peephole optimizer.
7189 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7191 Try to make the peephole optimizer smarter by maintaining
7192 an association between the assembly source code and the
7193 iCodes that originated them. Put this information to use
7194 with a new peephole rule condition "notVolatile" so that
7195 the rules can be aggressive yet still safe.
7200 * src/mcs51/peeph.def
7202 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7206 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7207 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7208 if the left or right operand symbols have the accuse flag set.
7210 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7212 Changed the type of the result of the ! (NOT) operator to char;
7213 previously it returned the same type as the source. This allows
7214 us to eliminate all the genFloatNot functions (all of its target
7215 implementations were very buggy) since !float can use the same
7218 * src/SDCCicode.c (ast2iCode): ! returns char
7219 * src/mcs51/gen.c (genNot, genNotFloat),
7220 * src/ds390/gen.c (genNot, genNotFloat),
7221 * src/z80/gen.c (genNot, genNotFloat),
7222 * src/pic/gen.c (genNot, genNotFloat),
7223 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7227 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7228 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7229 during interrupts. Ensure WSAVE is located at a shared bank address.
7230 2. Fixed page selection in some places
7231 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7232 the registers name strings.
7233 4. Fixed "signed / unsigned compare" compiler warnings.
7234 5. The PIC port manages its own allocation of the general purpose
7235 registers, but makes no attempt to reuse them. As a result when
7236 compiling it soon runs out of general purpose registers. Some
7237 additional code was added to the files pcode.c and device.c to walk
7238 through the function call tree and rename the registers so that they
7248 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7249 genPlus() & genMinus() when the result is the same as left or right
7251 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7255 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7257 Made bitfield a distinct type from bit so that bitfields
7258 convert as per ANSI C and bits retain their traditional
7259 boolean style behaviour. Implemented bitfield support in
7267 * src/ds390/gen.c: bit v bitfield split
7268 * src/z80/gen.c: New support for bitfields
7269 * support/regression/tests/bitfields.c: reenabled z80,
7272 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7274 Rules 246.x, 247.x relate to bitfields, the others speed up
7275 access to xdata mapped I/O devices.
7277 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7279 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7281 Cleaned up genPackBits and genUnpackBits and added two helper
7282 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7283 for literal assignments in genPackBits (thanks to Frieder for
7289 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7291 Fixed bug #748310 (pointer to function type mishandled when the
7292 function name is omitted). Also fixed a SIGSEGV when a function
7293 attribute (reentrant, etc) is used on a non-function or on a
7294 function but misplaced before the parameter list.
7296 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7298 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7321 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7323 Made the constant following the "interrupt" keyword optional. If
7324 omitted, the function will not automatically be given an entry
7325 in the interrupt vector table (similar to #pragma NOIV, but
7326 less syntacticly kludgy). The interrupt number is also now
7327 range checked. Also fixed a bug in the high order bit example

7348 unsigned, but are signed by default
7349 * src/SDCCval.c (constVal): rearranged
7350 * src/SDCCval.c (valMod): preliminary fix
7351 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7768 condition and ignore commands.
7770 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7772 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
7773 is in parts still quite out of date, I did changes as far as I felt makes sense
7774 for a non-native english speaker.
7775 Please feel free to add to the manual or to correct my changes.
7776 * doc/Makefile: undid touching the date of intermediate tex files.
7778 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7793 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7795 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
7796 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7797 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7798 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7801 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7803 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7804 the regression tests I'm not brave enough to enable 245.b, 245.c
7805 * doc/sdccman.lyx: added latex preamble for hyperref package.
7806 Using pdflatex this will give you a hyperlinked pdf file with
7807 bookmarks. (prepend '%' before /usepackage if this breaks something)
7809 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7823 Applied patch from bug 737905 (renamed yylineo to mylineno):
7830 * src/pic16/pcode.c: Cleaned warnings
7831 * src/pic16/pcodeflow.c: Cleaned warnings

7843 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7845 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7847 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7848 it can be defined with CFLAGS when running configure
7849 * src/SDCCmain.c: fixed compiling + linking with object files
7851 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7853 * configure.in: configure for pic16 port,
7854 added --disable-pic16-port
7855 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7856 * src/SDCCmain.c: linkOptions is changed to set *,
7857 added if/endif conditional macros to remove options help
7858 messages from optionsTable when a port is not configured, added
7859 support for the PIc16 port in the ports table, when executing
7860 the compiler with no port specified on command line, a default
7861 port is selected with the new macro DEFAULT_PORT which is
7862 defined in port.h, in setDefaultOptions() linkOptions is removed
7863 from initialization assignment, since now it is a set,
7864 parseCmdLine uses setParseWithComma for linkOptions, in
7865 linkEdit() linkOptions are accessed with new function indexSet()
7866 which returns the i'th item of a set variable. See SDCCset.c, in
7867 linkEdit() when calling buildCmdLine(), added linkOptions as
7868 last argument. Now users can pass arguments to gplink via the
7869 -Wl option, main() uses pic16glue() to glue up pic16 programs
7870 * src/SDCCpeeph.c: various changes to support pic16
7871 * src/SDCCset.c: added function void *indexSet(set *, int) to
7872 return the i'th item of the set

7877 added macro DEFAULT_PORT
7878 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
7879 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7881 * src/pic16/glue.c: commented out some error producing lines
7882 * src/pic16/main.c: __config directives are commented out to stop
7883 gpasm complaining and test the linkage with gplink, _linkCmd and
7884 _asmCmd changed to be more gplink and gpasm friendly
7885 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7886 produced an error when parsed, peep rule 12 is added to utilize
7887 movff, but it is commented out since the pCode does not support
7888 yet a command with 2 address arguments
7890 2003-05-18 <johan AT balder>
7892 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7893 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7912 on entry now. Add tbreak. Other enhancements and fixes for use
7915 2003-05-12 Borut Razem <borut.razem AT siol.net>
7917 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7919 2003-05-11 Borut Razem <borut.razem AT siol.net>
7921 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7922 the path of bin directory, so that PATH is the only env. variable, which has to be set
7923 in case of standard installation.
7924 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8953 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8955 * in \sdcc\as\mcs51\ changed these files in order to create an
8956 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8957 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8958 following files to include the previous two files: aslink.dsp,
8959 Makefile.aslink, Makefile.bcc, and Makefile.in.
8961 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8962 .adb instead of .cdb
8964 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8966 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8967 value from option --iram-size.
8969 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8971 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8974 2002-09-18 <wiml AT hhhh.org>
8976 * SDCClrange.h: exposed setFromRange() and setToRange()
8977 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8978 packRegsForAccUse() (bug 542397)
8979 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8980 multiple times and emitting the fetch operations more than once
8981 added aopGetUsesAcc() function to allow binary operators to
8982 fetch their operands in the correct order; made genMinus() emit
8983 compact code for X = LITERAL - Y
8985 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8986 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8987 sprintf() in line 1267.
8989 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8990 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8993 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8994 Changes to aslink (All the changes are marked with 'JCF'):
8996 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8999 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9000 area BSEG. Also moves, if possible, the DATA area down into the internal
9001 ram so more space is available.
9003 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9006 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9007 not bytes. Function summary() which creates a memory usage summary
9008 file with extension .mem. Reports of overlaping stack and small stack
9009 size. If the space for the stack is less than 16 bytes aslink trows a
9012 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9013 the 8051. Option 'y' for memory summary output file.
9015 Changes to sdcc (All the changes are marked with 'JCF'):
9017 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9019 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9020 overlaying area for it (uses RegBankUsed[4]).
9022 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9023 bank zero as used by default. By default aslink locates the stack
9024 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9025 the creation of the .mem file. Delegates the allocation of data area
9026 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9027 the begining of the stack area to aslink.
9029 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9030 glue() in SDCCglue.c creates an area for it.
9032 2002-09-03 Borut Razem <borut.razem AT siol.net>
9033 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9034 sdcc/src/pic/glue.c:
9035 introduced atexit() handler for teporay files removal in case of
9036 errors, assertions, ...
9038 2002-08-29 Borut Razem <borut.razem AT siol.net>
9039 * sdcc/support/cpp2/auto-host_vc_in.h:
9040 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9041 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9042 Maybe there is a similar problem with BORLANDC? It should be checked!
9044 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9045 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9046 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9047 was not executed, and the compiler (cl) launched a warning:
9048 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9050 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9068 * sdcc/src/yacc.dsp: added
9070 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9071 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9072 and insert the version number definitions from .version
9074 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp

9082 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9083 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9085 2002-08-11 Borut Razem <borut.razem AT siol.net>
9086 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9088 2002-08-10 Borut Razem <borut.razem AT siol.net>
9089 * src/SDCCmain.c (main):
9090 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9091 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9092 The consequence was that some temporary files were not removed.
9095 unification of code in functions tempfilename() and tempfile():
9096 function tempnam() is defined in Visual Studio 6.0 and .NET
9098 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9100 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9101 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9102 - removed compiler command line option /WX: Treats all warnings as errors
9103 - update a list of source files, included into the project
9105 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9106 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9107 changed project type to Generic Project so that can be correcly converted to VS.NET project
9109 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9111 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9115 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9116 added return 0 statements after assert() to make compiler happy
9118 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9119 added newline in the def file to keep MSC compiler satisfied
9121 * sdcc/src/z80/gen.c:
9122 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9123 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9124 - solved MSC error in function aopDump()
9126 * sdcc_vc.h: define PREFIX as "\\sdcc"
9128 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9184 were not getting allocated.
9186 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9189 Fixed left shift. Will promote the left side of a left shift
9190 if a) left shifting more than size of operand or b) when assigned
9191 to something size > size of left side
9193 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9303 * sdcc/src/SDCCloop.c:
9304 Previous fix was not good. basic blocks that have "break" or "return" are
9305 not really partof a loop , but live ranges used in these blocks should
9306 be live thru the entire loop, so set partOfLoop but don't add them to
9309 2002-02-21 <johan AT FRIJA>
