1786 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1787 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1788 always available in leading double underscore form. The C99 support is
1789 mostly missing, but it's a start.
1790 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1791 reserved identifier "__data".
1793 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1869 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1871 * device/lib/printf_large.c: removed inline assembly for portability and
1872 readability. Use printf_fast if speed or size are more important.
1873 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1874 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1876 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1878 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1879 prevent compiler warning
1881 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1883 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1884 moved to level 0 and declared as static. Also they are explicit
1885 placed in access bank. This was necessery because some times they
1886 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1887 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1888 optimizations. Currently only compare to unsigned char is implemented,
1889 * src/pic16/gen.c: added fReturnIdx array,
1890 * (struct resolvedIfx) is moved to gen.h and made public,
1891 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1892 * (aopForSym): added an optimization to directly store in stack of
1893 the operand of a SEND iCode,
1894 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1895 but as registers instead (AOP_REG) using the fReturnIdx array,
1896 * (pic16_freeAsmop): remove the freed register from the
1897 _G.sregsAlloc field,
1898 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1899 a compare of 'WREG',
1900 * (pic16_popGetTempRegCond): changed function prototype, now
1901 function takes also a bitVector argument v which holds the current
1902 set of registers that are allocated for stack access by aopForSym,
1903 registers allocated in aopForSym for accessing stack symbols are not
1904 any more part of the functions usedRegs field,
1905 * (genCall): some times aopOp is called for a stack variable to be
1906 send, aopForSym might perform the push, if this is true make sure
1907 that genCall doesn't push the variable twice by testing _G.resDirect,
1908 * (genFunction): changed testing for unspecified interrupt number
1909 from 256 to INTNO_UNSPEC,
1910 * modified selection scheme of frame pointer generation. Previously
1911 if function did use local registers a frame pointer was generated,
1912 now a frame pointer is generated only if function has arguments
1913 (that need PLUSW2 register access), or has stack arguments, or the
1914 compiler is not instructed to omit the frame pointer,
1915 * (genEndFunction): before restoring local registers that were saved
1916 in the function preamble, also restore the registers that *might*
1917 have been allocated for stack access,
1918 * (genRet): removed some old comments,
1919 * (genCmp, the active (RN's) version): added a call to the
1920 pic16_genCmp_special function to perform the compare with a more
1921 robust and optimized way,
1922 * (genInline): a feature has been added in inline code generation,
1923 which allows a wildcard variable substitution when writing inline
1924 assembly. Code is incomplete and experimental therefore undocumented,
1925 * (genCast): changed order of aopOp for result and right to allow
1926 aopForSym to directly load the result if possible,
1927 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1928 perform an optimized compare on some selected special occasions,
1929 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1930 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1931 generate an IVT any more,
1932 * src/pic16/main.c (pic16_optionsTable): added command line option
1934 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1935 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1937 * src/pic16/NOTES: Raphael Neider added in list of active developers
1938 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1939 jumptable_end to prevent bug #,
1940 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1941 inCond and outCond fields,
1942 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1943 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1944 turn off register spilling,
1945 * (packRegsForOneUse): synced with other ports' versions although it
1946 is not used currently,
1947 * (pic16_packRegisters): added an optimization while reading
1948 structure bitfields, some registers may be saved (malloc code is
1949 decreased by 80 bytes)
1951 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1953 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1954 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1955 this can be optimized more?
1957 2005-03-10 Raphael Neider <rneider AT web.de>
1959 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1960 genNearPointerGet): (hopefully) fixed access to bitfields via
1961 pointers (p->bitN = x; and x = p->bitN; failed)
1963 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2140 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2141 (sizeof(sectNames) changed to sizeof(sectName))
2142 Both patches fix segfaults under MinGW.

2149 of (byte sized) temporaries (assign them to WREG for now)
2150 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2151 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2152 this might fix SIGSEGVs on MinGW...
2153 * src/SDCCopt.c (killDeadCode): restored original behaviour
2154 (volatile operands might get thrown away though)
2156 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2158 * src/pic16/gen.c: fixed bug #1106975,

2593 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2595 Adding support for replacing ljmps with sjmps in jumptables
2596 generated for switch statements. For now you need to set the
2597 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2598 Now 4 algorithms for mcs51 jumptable generation are used:
2599 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2600 addresses loaded pc-relative for up to 112 cases and stack-pushing
2601 target addresses loaded with offset from dptr for up to 256 cases.
2603 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2604 * src/mcs51/main.c: adapted constants for switch table generation
2605 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2625 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2627 Large cummulative patch for pic16 port.
2628 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2629 to call when a stack overflow occurs,
2630 * (malloc.h): added CVS Id tag,
2631 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2633 * added libc directory. The current version of LibC contains string
2634 functions, ctype functions and macros and some functions of the
2635 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2636 be extensively tested in the future. Standard disclaimer here.
2637 Library is not automatically build yet. But one can build it by
2638 invoking 'make' inside the libc directory.
2639 * added ADC library under libio. Preliminary version yet.
2641 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2642 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2643 aopForRemat() now and not by pic16_aopOp(),

2645 temporary registers, its a buggy feature and will be removed,
2646 * (pic16_popGet): set register instance field in AOP_CRY,
2647 * (pic16_outBitC): fixed for results in size greater than 1,
2648 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2649 * (pic16_storeForReturn): optimized return of 0,
2650 * (genCmp): experimental code for new genCmp which uses PIC18's
2651 special compare&skip instructions. Initial tests fail some times
2652 with variables grater than 1 byte in size, so new code is disabled,
2653 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2655 * (genCast): began a fix to optimize the casting of a bit to another
2656 bit, now assigning a bitfield to another bitfield will fail, sorry,
2657 * src/pic16/main.c: disabled the use of lr-support feature,
2658 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2659 * added some function prototypes, added function _debugf prototype,
2660 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2661 bits with offset (case PO_GPR_BIT),
2662 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2664 * (isBankInstruction): modified to return 0 for no banking instruction,
2665 and 1 for banking instruction,
2666 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2667 caused stop processing pCodes after a inline assembly block,
2668 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2669 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2670 registers when it shouldn't,
2671 * src/pic16/ralloc.c (allocReg): add preliminary support for
2672 supporting a limited set of temporary registers,
2674 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2676 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2677 genDataPointerSet): ensure assignments always copy in MSB to LSB
2679 (loadRegFromAop): recognize CLRH optimization,
2680 (genFunction): optimize RECEIVE iCodes in reentrant functions
2682 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2684 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2685 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2687 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2694 * device/lib/_gptrgetc.c (_gptrgetc),
2695 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2696 instead of sjmp to ret
2697 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2698 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2700 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5683 to be linked with the current source (-l arguments). Changes
5684 currently will affect only the pic16 port.
5685 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5686 include path the port specific paths and port specific libraries,
5687 * gplink command now contains the $3 argument,
5688 * src/pic16/device.h,
5689 * src/pic16/device.c,: structure PIC_device is made public and
5690 renamed to PIC16_device, the same for variable Pics which is renamed
5691 to Pics16. Updated all references to them.
5692 * src/pic16/glue.c (pic16glue): corrected bug with code
5693 initialization which bypassed the variable initializations block.
5695 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5696 COMPILE_FLAGS and added the --nostdinc option
5698 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5700 * device/include/mc68hc908jb8.h: Register defs for another member
5701 of the hc08 family. Contributed by Bjorn Bringert - thanks!
5703 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5705 Documenting changes from previous commits.
5706 * configure.in (version 1.56),
5707 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5708 when generating output files to configure the pic16 library,
5709 but now I've commented it out, since gputils aren't installed in the
5710 SF compile farm, so library won't compile
5712 * device/lib/Makefile.in (version 1.56): initially I've added in
5713 target 'all' the prerequestive 'model-pic16' so it compiled the
5714 pic16 library, but now I've commented it out for the same reasons
5716 * added targets 'model-pic16' and 'objects-pic16' to compile the
5718 * added target 'port-specific-objects-pic16' to handle the
5719 generated libraries and copy them into the build/ directory
5720 * added target 'clean-intermediate-pic16' to clean intermediate
5721 files into pic16 directory
5722 * in target 'installdirs' added line to create directory pic16 in
5723 the installation path
5725 * device/include/Makefile.in (version 1.11): in target 'install'
5726 added lines to copy all header files to installation path,
5727 * in target 'installdirs' added line create directory for pic16
5728 headers in the installation path

5743 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5744 option so that it actually works. Made it specific to the z80, since
5745 the gbz80 doesn't have these kinds of I/O ports.
5747 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5749 * device/include/z180.h,

5762 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5764 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5765 changed interrupt vector table generation to only emit declared vectors.
5766 * device/include/Makefile.in: added missing backslash
5767 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5771 Mainly changes to support compilation of the device libraries
5772 * src/pic16/device.c: stack is allocated via symbol and not
5773 via literal number. The symbol is placed in the corresponding
5774 position of the data ram
5775 * (pic16_dump_section): relocatable and absolute uninitialized
5776 data are now emitted in sorted order to reduce section naming,
5777 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5778 weren't marked as being in the access bank,
5780 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5782 Added portion of GNU PIC Library under the directory
5783 device/include/pic16 and device/lib/pic16. These files
5784 contain the declarations of SFRs for the PIC18Fxx2 devices.
5785 The directory is initialized via configure from toplevel.
5787 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5789 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5790 the spilllocations to be compared correctly
5792 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5794 * src/SDCCast.c (decorateType): fixed bug introduced today
5796 2004-01-12 Borut Razem <borut.razem AT siol.net>

5812 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5814 * doc/sdccman.lyx: Moved and added some sections, small changes
5815 all over. Telling LaTeX to be less strict with word spacing
5816 to better keep the right margin. Changed some notes about
5817 maintainance of the ports in section 3.2.1 - is it OK like this?
5819 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5856 UPPER for immediate operands,
5857 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5859 * src/pic16/peeph.def: all peepholes with movff are commented out,
5860 because there is a problem in the pcode peep optimizer,
5861 * src/pic16/ralloc.c: the register allocator can now reuse local
5862 function symbols for another function. This saves register usage.
5863 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5865 Added file src/pic16/NOTES with information about program writing on
5866 the current port version.

5875 * src/SDCCmain.c : fixed #872250: -l command line defined library
5876 files are scanned before standard library files
5878 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5895 gen51Code): more efficient parameter receive for --model-large
5898 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5901 * src/z80/main.c: added missed needLinkerScript flags (more than
5902 one port structure defined in these file)
5903 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5919 needLinkerScript flag
5921 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5922 * src/pic/glue.c: added variable udata_section_name to
5923 override default uninitialized data segment definition for
5924 devices only with SHAREBANK memory (reported from Erik Epetrich)
5925 * (pic14emitOverlay): modified to emit a commented overlay segment
5926 directive when no overlay data exist
5927 * (picglue): modified to emit uninitialized data segment
5928 according to udata_section_name

5938 2004-01-07 Borut Razem <borut.razem AT siol.net>
5940 * support/scripts/sdcc.nsi: update PATH
5941 * support/scripts/sdcc.ico: craeted
5943 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5946 * doc/Makefile: fix install
5948 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5950 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5952 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5954 include information about variables allocated to the overlay
5957 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5959 * as/mcs51/lkmain.c: Help about -Y option

5971 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5973 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5974 (default behaviour).
5976 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5978 A python script to validate compiler diagnostic messages. It can be
5979 used to verify that sdcc complains about bad c source code and
5980 gives a good location of the error.
5981 * support/valdiag/Makefile,
5982 * support/valdiag/valdiag.py,
5983 * support/valdiag/tests/*
5985 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5998 * src/common.h: added ifndef/define/endif macros
5999 around the header file.
6000 Bug reported from Jesus Calvino-Fraga
6002 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6004 * sdcc.spec: updated
6005 * device/include/Makefile.in: don't install CVS directories
6006 * device/lib/Makefile.in: added removal of CVS directories after install
6007 * doc/Makefile: fixed install, added local_icons
6008 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6009 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6010 * src/ds390/gen.c (genRightShift): fixed bug #870788
6011 * src/SDCCast.c (decorateType): fixed bug #870781
6013 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6015 PIC16 port related changes:
6016 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6017 added variable stackPos,
6019 * gen.c: genCall, assignResultValue: added support for
6020 pushing/retrieving function parameters to/from stack,
6021 genFunction,genEndFunction: setup stack frame for the
6023 genAddrOf: will be changed according to bug 863624
6025 * added files genutils.c and genutils.h which contain gen*
6026 debugged and optimised functions extracted from gen.c
6028 * glue.c: added variable 'externs' which holds extern symbols,
6029 pic16emitRegularMap: is modified to properly handle relocatable
6030 symbols under the new scheme,
6031 pic16createInterruptVect: is modified
6032 pic16printPublics: is modified to emit 'global' assembler directives,
6033 added pic16_printExterns to print extern symbols,
6034 pic16glue: initializes stack/frame pointer in the beginning of
6035 the assembly output. Temporary hack, will be corrected later,
6036 because gplink yet does not support stack and SDCC does not
6037 yet support a type of crt0.o object to create the final binary.
6039 * Removed many lines that contain 8051 legacy code.
6040 * The code is finally placed under a 'code' directive.
6041 * Added port specific options.
6043 * _process_pragma: simplified since now we do not need *special*
6044 include file to define SFR registers. But a separate header
6045 will be needed. This will be developed later.
6046 * _pic16_parseOptions: added, parses port specific options:
6047 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6048 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6049 --preplace-udata-with=
6051 * _pic16_setDefaultOptions: modified to initialize section names,
6052 but hack is temporarly out of order since it needs improvement.
6053 * _pic16_genAssemblerPreamble: configuration words are emitted by
6054 their address instead of their name. This part is incomplete and
6055 supports only the 18Fxx2 devices. Other devices will emit an error
6056 during assembly since they do not contain the same set of config
6058 * _pic16_genIVT: is modified,
6060 * pcode.c: added definitions for some hardware registers that are needed
6062 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6063 All PCI entries are updated. Now LFSR is supported.
6064 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6065 * added pic16_newpCodeOpLit2 to support instructions with
6066 two literal arguments
6067 * pic16_pCode2str: corrected code that emits assembler instructions
6068 with two literal operands and those that have an access bit modifier
6069 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6070 this fixes a bug which caused some labels to be lost, when an
6071 assembler directive was added, i.e. banksel,
6072 * pic16_FixRegisterBanking: improved logic that causes the insertion
6074 * InlineFunction: functions that are called once, are not any more
6075 inlined. This can be a port option in the future,
6077 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6079 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6080 hold the corresponding uninitialized symbols,
6081 * pic16_allocProcessorRegister: registers have explicit marked the
6083 * pic16_allocInternalRegister: registers are explicit marked as
6085 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6086 processing list, so bit registers were lost,
6089 * ralloc.h: added field 'accessBank' and original symbol operand
6090 in register definition,
6091 * removed the field isMapped from register definition,
6093 ** Several functions have been removed from various sources:
6094 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6095 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6096 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6097 pic16_assignRelocatableRegisters
6099 ** others have been introduced:
6100 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6101 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6103 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6105 * support/scripts/inc2h.pl: changed definition of BIT_AT
6106 to emit 'sbit at' instead of 'bit at'. This was a request.
6108 PIC16 port related preliminary changes:
6109 * gen.c: prefixed function popRegFromString with
6110 pic16_ and all references to it corrected
6111 * pcode.c: all pic16_pc_* hardware registers prefixed
6112 with underscore (_),
6113 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6114 * ralloc.c: newReg(): when register is REG_SFR then
6115 set address to rIdx,
6116 pic16_allocProcessorRegister(): marks register wasUsed=0
6117 pic16_writeUsedRegs(): added a call to assign processor
6118 registers via pic16_assignFixedRegisters
6120 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6122 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6123 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6124 variables in unused register banks. Also the SSEG is placed
6125 wherever there is enough space for it, and IDATA can be anywhere
6126 in internal RAM. For now compile using -Wl-Y[stack_size].
6127 The mem file is different for this option as well, since it
6128 makes no sense of talking about DSEG lenght.
6130 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6132 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6133 in certain cases, e.g. when ROM assignment, patch provided
6134 from Albert den Haan.
6136 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7179 A few small changes that speed up the peephole optimizer.
7183 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7185 Try to make the peephole optimizer smarter by maintaining
7186 an association between the assembly source code and the
7187 iCodes that originated them. Put this information to use
7188 with a new peephole rule condition "notVolatile" so that
7189 the rules can be aggressive yet still safe.
7194 * src/mcs51/peeph.def
7196 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7200 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7201 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7202 if the left or right operand symbols have the accuse flag set.
7204 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7206 Changed the type of the result of the ! (NOT) operator to char;
7207 previously it returned the same type as the source. This allows
7208 us to eliminate all the genFloatNot functions (all of its target
7209 implementations were very buggy) since !float can use the same
7212 * src/SDCCicode.c (ast2iCode): ! returns char
7213 * src/mcs51/gen.c (genNot, genNotFloat),
7214 * src/ds390/gen.c (genNot, genNotFloat),
7215 * src/z80/gen.c (genNot, genNotFloat),

7221 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7222 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7223 during interrupts. Ensure WSAVE is located at a shared bank address.
7224 2. Fixed page selection in some places
7225 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7226 the registers name strings.
7227 4. Fixed "signed / unsigned compare" compiler warnings.
7228 5. The PIC port manages its own allocation of the general purpose
7229 registers, but makes no attempt to reuse them. As a result when
7230 compiling it soon runs out of general purpose registers. Some
7231 additional code was added to the files pcode.c and device.c to walk
7232 through the function call tree and rename the registers so that they
7242 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7243 genPlus() & genMinus() when the result is the same as left or right

7249 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7251 Made bitfield a distinct type from bit so that bitfields
7252 convert as per ANSI C and bits retain their traditional
7253 boolean style behaviour. Implemented bitfield support in
7261 * src/ds390/gen.c: bit v bitfield split
7262 * src/z80/gen.c: New support for bitfields
7263 * support/regression/tests/bitfields.c: reenabled z80,
7266 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7268 Rules 246.x, 247.x relate to bitfields, the others speed up
7269 access to xdata mapped I/O devices.
7271 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7273 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7275 Cleaned up genPackBits and genUnpackBits and added two helper
7276 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7277 for literal assignments in genPackBits (thanks to Frieder for
7283 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7285 Fixed bug #748310 (pointer to function type mishandled when the
7286 function name is omitted). Also fixed a SIGSEGV when a function
7287 attribute (reentrant, etc) is used on a non-function or on a
7288 function but misplaced before the parameter list.
7290 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7292 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7315 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7317 Made the constant following the "interrupt" keyword optional. If
7318 omitted, the function will not automatically be given an entry
7319 in the interrupt vector table (similar to #pragma NOIV, but
7320 less syntacticly kludgy). The interrupt number is also now
7321 range checked. Also fixed a bug in the high order bit example

7342 unsigned, but are signed by default
7343 * src/SDCCval.c (constVal): rearranged
7344 * src/SDCCval.c (valMod): preliminary fix
7345 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7762 condition and ignore commands.
7764 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7766 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
7767 is in parts still quite out of date, I did changes as far as I felt makes sense
7768 for a non-native english speaker.
7769 Please feel free to add to the manual or to correct my changes.
7770 * doc/Makefile: undid touching the date of intermediate tex files.
7772 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7787 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7789 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
7790 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7791 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7792 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7795 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7797 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7798 the regression tests I'm not brave enough to enable 245.b, 245.c
7799 * doc/sdccman.lyx: added latex preamble for hyperref package.
7800 Using pdflatex this will give you a hyperlinked pdf file with
7801 bookmarks. (prepend '%' before /usepackage if this breaks something)
7803 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7817 Applied patch from bug 737905 (renamed yylineo to mylineno):
7824 * src/pic16/pcode.c: Cleaned warnings
7825 * src/pic16/pcodeflow.c: Cleaned warnings

7839 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7841 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7842 it can be defined with CFLAGS when running configure
7843 * src/SDCCmain.c: fixed compiling + linking with object files
7845 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7847 * configure.in: configure for pic16 port,
7848 added --disable-pic16-port
7849 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7850 * src/SDCCmain.c: linkOptions is changed to set *,
7851 added if/endif conditional macros to remove options help
7852 messages from optionsTable when a port is not configured, added
7853 support for the PIc16 port in the ports table, when executing
7854 the compiler with no port specified on command line, a default
7855 port is selected with the new macro DEFAULT_PORT which is
7856 defined in port.h, in setDefaultOptions() linkOptions is removed
7857 from initialization assignment, since now it is a set,
7858 parseCmdLine uses setParseWithComma for linkOptions, in
7859 linkEdit() linkOptions are accessed with new function indexSet()
7860 which returns the i'th item of a set variable. See SDCCset.c, in
7861 linkEdit() when calling buildCmdLine(), added linkOptions as
7862 last argument. Now users can pass arguments to gplink via the
7863 -Wl option, main() uses pic16glue() to glue up pic16 programs
7864 * src/SDCCpeeph.c: various changes to support pic16
7865 * src/SDCCset.c: added function void *indexSet(set *, int) to
7866 return the i'th item of the set

7871 added macro DEFAULT_PORT
7872 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
7873 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7875 * src/pic16/glue.c: commented out some error producing lines
7876 * src/pic16/main.c: __config directives are commented out to stop
7877 gpasm complaining and test the linkage with gplink, _linkCmd and
7878 _asmCmd changed to be more gplink and gpasm friendly
7879 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7880 produced an error when parsed, peep rule 12 is added to utilize
7881 movff, but it is commented out since the pCode does not support
7882 yet a command with 2 address arguments
7884 2003-05-18 <johan AT balder>
7886 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7887 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7911 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7913 2003-05-11 Borut Razem <borut.razem AT siol.net>
7915 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7916 the path of bin directory, so that PATH is the only env. variable, which has to be set
7917 in case of standard installation.
7918 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8947 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8949 * in \sdcc\as\mcs51\ changed these files in order to create an
8950 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8951 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8952 following files to include the previous two files: aslink.dsp,
8953 Makefile.aslink, Makefile.bcc, and Makefile.in.
8955 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8956 .adb instead of .cdb
8958 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8960 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8961 value from option --iram-size.
8963 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8965 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8968 2002-09-18 <wiml AT hhhh.org>
8970 * SDCClrange.h: exposed setFromRange() and setToRange()
8971 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8972 packRegsForAccUse() (bug 542397)
8973 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8974 multiple times and emitting the fetch operations more than once
8975 added aopGetUsesAcc() function to allow binary operators to
8976 fetch their operands in the correct order; made genMinus() emit
8977 compact code for X = LITERAL - Y
8979 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8980 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8981 sprintf() in line 1267.
8983 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8984 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8987 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8988 Changes to aslink (All the changes are marked with 'JCF'):
8990 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8993 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8994 area BSEG. Also moves, if possible, the DATA area down into the internal
8995 ram so more space is available.
8997 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9000 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9001 not bytes. Function summary() which creates a memory usage summary
9002 file with extension .mem. Reports of overlaping stack and small stack
9003 size. If the space for the stack is less than 16 bytes aslink trows a
9006 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9007 the 8051. Option 'y' for memory summary output file.
9009 Changes to sdcc (All the changes are marked with 'JCF'):
9011 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9013 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9014 overlaying area for it (uses RegBankUsed[4]).
9016 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9017 bank zero as used by default. By default aslink locates the stack
9018 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9019 the creation of the .mem file. Delegates the allocation of data area
9020 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9021 the begining of the stack area to aslink.
9023 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9024 glue() in SDCCglue.c creates an area for it.
9026 2002-09-03 Borut Razem <borut.razem AT siol.net>
9027 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9028 sdcc/src/pic/glue.c:
9029 introduced atexit() handler for teporay files removal in case of
9030 errors, assertions, ...
9032 2002-08-29 Borut Razem <borut.razem AT siol.net>
9033 * sdcc/support/cpp2/auto-host_vc_in.h:
9034 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9035 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9036 Maybe there is a similar problem with BORLANDC? It should be checked!
9038 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9039 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9040 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9041 was not executed, and the compiler (cl) launched a warning:
9042 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9044 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9045 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

9062 * sdcc/src/yacc.dsp: added
9064 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9065 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9066 and insert the version number definitions from .version
9068 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9070 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9074 removed from CVS, generated automatically
9076 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9077 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9079 2002-08-11 Borut Razem <borut.razem AT siol.net>
9080 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9082 2002-08-10 Borut Razem <borut.razem AT siol.net>
9083 * src/SDCCmain.c (main):
9084 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9085 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9086 The consequence was that some temporary files were not removed.
9089 unification of code in functions tempfilename() and tempfile():
9090 function tempnam() is defined in Visual Studio 6.0 and .NET
9092 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9094 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9095 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9096 - removed compiler command line option /WX: Treats all warnings as errors
9097 - update a list of source files, included into the project
9099 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9100 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9101 changed project type to Generic Project so that can be correcly converted to VS.NET project
9103 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9105 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9107 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9109 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9110 added return 0 statements after assert() to make compiler happy
9112 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9113 added newline in the def file to keep MSC compiler satisfied
9115 * sdcc/src/z80/gen.c:
9116 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9117 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9118 - solved MSC error in function aopDump()
9120 * sdcc_vc.h: define PREFIX as "\\sdcc"
9122 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9178 were not getting allocated.
9180 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9183 Fixed left shift. Will promote the left side of a left shift
9184 if a) left shifting more than size of operand or b) when assigned
9185 to something size > size of left side
9187 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9297 * sdcc/src/SDCCloop.c:
9298 Previous fix was not good. basic blocks that have "break" or "return" are
9299 not really partof a loop , but live ranges used in these blocks should
9300 be live thru the entire loop, so set partOfLoop but don't add them to
9303 2002-02-21 <johan AT FRIJA>
