1897 * device/lib/printf_large.c: removed inline assembly for portability and
1898 readability. Use printf_fast if speed or size are more important.
1899 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1900 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1902 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1904 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1905 prevent compiler warning
1907 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1909 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1910 moved to level 0 and declared as static. Also they are explicit
1911 placed in access bank. This was necessery because some times they
1912 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1913 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1914 optimizations. Currently only compare to unsigned char is implemented,
1915 * src/pic16/gen.c: added fReturnIdx array,
1916 * (struct resolvedIfx) is moved to gen.h and made public,
1917 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1918 * (aopForSym): added an optimization to directly store in stack of
1919 the operand of a SEND iCode,
1920 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1921 but as registers instead (AOP_REG) using the fReturnIdx array,
1922 * (pic16_freeAsmop): remove the freed register from the
1923 _G.sregsAlloc field,
1924 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1925 a compare of 'WREG',
1926 * (pic16_popGetTempRegCond): changed function prototype, now
1927 function takes also a bitVector argument v which holds the current
1928 set of registers that are allocated for stack access by aopForSym,
1929 registers allocated in aopForSym for accessing stack symbols are not
1930 any more part of the functions usedRegs field,
1931 * (genCall): some times aopOp is called for a stack variable to be
1932 send, aopForSym might perform the push, if this is true make sure
1933 that genCall doesn't push the variable twice by testing _G.resDirect,
1934 * (genFunction): changed testing for unspecified interrupt number
1935 from 256 to INTNO_UNSPEC,
1936 * modified selection scheme of frame pointer generation. Previously
1937 if function did use local registers a frame pointer was generated,
1938 now a frame pointer is generated only if function has arguments
1939 (that need PLUSW2 register access), or has stack arguments, or the
1940 compiler is not instructed to omit the frame pointer,
1941 * (genEndFunction): before restoring local registers that were saved
1942 in the function preamble, also restore the registers that *might*
1943 have been allocated for stack access,
1944 * (genRet): removed some old comments,
1945 * (genCmp, the active (RN's) version): added a call to the
1946 pic16_genCmp_special function to perform the compare with a more
1947 robust and optimized way,
1948 * (genInline): a feature has been added in inline code generation,
1949 which allows a wildcard variable substitution when writing inline
1950 assembly. Code is incomplete and experimental therefore undocumented,
1951 * (genCast): changed order of aopOp for result and right to allow
1952 aopForSym to directly load the result if possible,
1953 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1954 perform an optimized compare on some selected special occasions,
1955 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1956 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1957 generate an IVT any more,
1958 * src/pic16/main.c (pic16_optionsTable): added command line option
1960 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1961 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1963 * src/pic16/NOTES: Raphael Neider added in list of active developers
1964 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1965 jumptable_end to prevent bug #,
1966 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1967 inCond and outCond fields,
1968 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1969 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1970 turn off register spilling,
1971 * (packRegsForOneUse): synced with other ports' versions although it
1972 is not used currently,
1973 * (pic16_packRegisters): added an optimization while reading
1974 structure bitfields, some registers may be saved (malloc code is
1975 decreased by 80 bytes)
1977 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1979 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1980 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1981 this can be optimized more?
1983 2005-03-10 Raphael Neider <rneider AT web.de>
1985 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1986 genNearPointerGet): (hopefully) fixed access to bitfields via
1987 pointers (p->bitN = x; and x = p->bitN; failed)

2604 (setFromConditionArgs): friendly operand parser for peephole rules,
2605 (operandBaseName, operandsNotRelated): new peephole condition
2606 "operandsNotRelated" -- similar to "operandsNotSame", but takes

2619 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2621 Adding support for replacing ljmps with sjmps in jumptables
2622 generated for switch statements. For now you need to set the
2623 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2624 Now 4 algorithms for mcs51 jumptable generation are used:
2625 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2626 addresses loaded pc-relative for up to 112 cases and stack-pushing
2627 target addresses loaded with offset from dptr for up to 256 cases.
2629 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2630 * src/mcs51/main.c: adapted constants for switch table generation
2631 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2653 Large cummulative patch for pic16 port.
2654 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2655 to call when a stack overflow occurs,
2656 * (malloc.h): added CVS Id tag,
2657 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2659 * added libc directory. The current version of LibC contains string
2660 functions, ctype functions and macros and some functions of the
2661 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2662 be extensively tested in the future. Standard disclaimer here.
2663 Library is not automatically build yet. But one can build it by
2664 invoking 'make' inside the libc directory.
2665 * added ADC library under libio. Preliminary version yet.
2667 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2674 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2675 * (pic16_storeForReturn): optimized return of 0,
2676 * (genCmp): experimental code for new genCmp which uses PIC18's
2677 special compare&skip instructions. Initial tests fail some times
2678 with variables grater than 1 byte in size, so new code is disabled,
2679 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2681 * (genCast): began a fix to optimize the casting of a bit to another
2682 bit, now assigning a bitfield to another bitfield will fail, sorry,
2683 * src/pic16/main.c: disabled the use of lr-support feature,
2684 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2685 * added some function prototypes, added function _debugf prototype,
2686 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2687 bits with offset (case PO_GPR_BIT),
2688 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2690 * (isBankInstruction): modified to return 0 for no banking instruction,
2691 and 1 for banking instruction,
2692 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2693 caused stop processing pCodes after a inline assembly block,
2694 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2695 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2696 registers when it shouldn't,
2697 * src/pic16/ralloc.c (allocReg): add preliminary support for
2698 supporting a limited set of temporary registers,
2700 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2702 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2703 genDataPointerSet): ensure assignments always copy in MSB to LSB
2705 (loadRegFromAop): recognize CLRH optimization,
2706 (genFunction): optimize RECEIVE iCodes in reentrant functions
2708 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2710 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2711 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2713 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2719 * device/lib/_gptrget.c (_gptrget),
2720 * device/lib/_gptrgetc.c (_gptrgetc),
2721 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2722 instead of sjmp to ret
2723 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2724 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2726 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5705 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5707 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5708 loaded with the linker search paths (-L arguments) and the libraries
5709 to be linked with the current source (-l arguments). Changes
5710 currently will affect only the pic16 port.
5711 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5712 include path the port specific paths and port specific libraries,
5713 * gplink command now contains the $3 argument,
5714 * src/pic16/device.h,
5715 * src/pic16/device.c,: structure PIC_device is made public and
5716 renamed to PIC16_device, the same for variable Pics which is renamed
5717 to Pics16. Updated all references to them.
5718 * src/pic16/glue.c (pic16glue): corrected bug with code
5719 initialization which bypassed the variable initializations block.

5731 Documenting changes from previous commits.
5732 * configure.in (version 1.56),
5733 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5734 when generating output files to configure the pic16 library,
5735 but now I've commented it out, since gputils aren't installed in the
5736 SF compile farm, so library won't compile
5738 * device/lib/Makefile.in (version 1.56): initially I've added in
5739 target 'all' the prerequestive 'model-pic16' so it compiled the
5740 pic16 library, but now I've commented it out for the same reasons
5742 * added targets 'model-pic16' and 'objects-pic16' to compile the
5744 * added target 'port-specific-objects-pic16' to handle the
5745 generated libraries and copy them into the build/ directory
5746 * added target 'clean-intermediate-pic16' to clean intermediate
5747 files into pic16 directory
5748 * in target 'installdirs' added line to create directory pic16 in
5749 the installation path
5751 * device/include/Makefile.in (version 1.11): in target 'install'
5752 added lines to copy all header files to installation path,
5753 * in target 'installdirs' added line create directory for pic16
5754 headers in the installation path

5769 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5770 option so that it actually works. Made it specific to the z80, since
5771 the gbz80 doesn't have these kinds of I/O ports.
5773 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5775 * device/include/z180.h,

5788 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5790 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5791 changed interrupt vector table generation to only emit declared vectors.
5792 * device/include/Makefile.in: added missing backslash
5793 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5795 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5797 Mainly changes to support compilation of the device libraries
5798 * src/pic16/device.c: stack is allocated via symbol and not
5799 via literal number. The symbol is placed in the corresponding
5800 position of the data ram
5801 * (pic16_dump_section): relocatable and absolute uninitialized
5802 data are now emitted in sorted order to reduce section naming,
5803 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5804 weren't marked as being in the access bank,
5806 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5808 Added portion of GNU PIC Library under the directory
5809 device/include/pic16 and device/lib/pic16. These files
5810 contain the declarations of SFRs for the PIC18Fxx2 devices.
5811 The directory is initialized via configure from toplevel.
5813 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5815 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5816 the spilllocations to be compared correctly
5818 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5820 * src/SDCCast.c (decorateType): fixed bug introduced today
5822 2004-01-12 Borut Razem <borut.razem AT siol.net>
5824 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5827 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5829 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5830 in simpler and even better code
5832 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5834 * src/SDCCicode.c (operandOperation): fixed bug #874819

5840 * doc/sdccman.lyx: Moved and added some sections, small changes
5841 all over. Telling LaTeX to be less strict with word spacing
5842 to better keep the right margin. Changed some notes about
5843 maintainance of the ports in section 3.2.1 - is it OK like this?
5845 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5847 SDCC source changes:
5848 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5881 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5882 UPPER for immediate operands,
5883 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5885 * src/pic16/peeph.def: all peepholes with movff are commented out,
5886 because there is a problem in the pcode peep optimizer,
5887 * src/pic16/ralloc.c: the register allocator can now reuse local
5888 function symbols for another function. This saves register usage.
5889 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5891 Added file src/pic16/NOTES with information about program writing on
5892 the current port version.

5901 * src/SDCCmain.c : fixed #872250: -l command line defined library
5902 files are scanned before standard library files
5904 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5921 gen51Code): more efficient parameter receive for --model-large
5924 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5927 * src/z80/main.c: added missed needLinkerScript flags (more than
5928 one port structure defined in these file)
5929 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5945 needLinkerScript flag
5947 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5948 * src/pic/glue.c: added variable udata_section_name to
5949 override default uninitialized data segment definition for
5950 devices only with SHAREBANK memory (reported from Erik Epetrich)
5951 * (pic14emitOverlay): modified to emit a commented overlay segment
5952 directive when no overlay data exist
5953 * (picglue): modified to emit uninitialized data segment
5954 according to udata_section_name

5959 arguments via -W option
5960 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5961 object file from '.rel' to '.o' in port->linker structure,
5962 changed size of fptr from 2 to 3 in port structure
5964 2004-01-07 Borut Razem <borut.razem AT siol.net>
5966 * support/scripts/sdcc.nsi: update PATH
5967 * support/scripts/sdcc.ico: craeted
5969 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5972 * doc/Makefile: fix install
5974 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5976 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5978 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5980 include information about variables allocated to the overlay
5983 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5985 * as/mcs51/lkmain.c: Help about -Y option

5997 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5999 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6000 (default behaviour).
6002 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6004 A python script to validate compiler diagnostic messages. It can be
6005 used to verify that sdcc complains about bad c source code and
6006 gives a good location of the error.
6007 * support/valdiag/Makefile,
6008 * support/valdiag/valdiag.py,
6009 * support/valdiag/tests/*
6011 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6013 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6022 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6024 * src/common.h: added ifndef/define/endif macros
6025 around the header file.
6026 Bug reported from Jesus Calvino-Fraga
6028 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6030 * sdcc.spec: updated
6031 * device/include/Makefile.in: don't install CVS directories
6032 * device/lib/Makefile.in: added removal of CVS directories after install
6033 * doc/Makefile: fixed install, added local_icons
6034 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6035 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6036 * src/ds390/gen.c (genRightShift): fixed bug #870788
6037 * src/SDCCast.c (decorateType): fixed bug #870781
6039 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6041 PIC16 port related changes:
6042 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6043 added variable stackPos,
6045 * gen.c: genCall, assignResultValue: added support for
6046 pushing/retrieving function parameters to/from stack,
6047 genFunction,genEndFunction: setup stack frame for the
6049 genAddrOf: will be changed according to bug 863624
6051 * added files genutils.c and genutils.h which contain gen*
6052 debugged and optimised functions extracted from gen.c
6054 * glue.c: added variable 'externs' which holds extern symbols,
6055 pic16emitRegularMap: is modified to properly handle relocatable
6056 symbols under the new scheme,
6057 pic16createInterruptVect: is modified
6058 pic16printPublics: is modified to emit 'global' assembler directives,
6059 added pic16_printExterns to print extern symbols,
6060 pic16glue: initializes stack/frame pointer in the beginning of
6061 the assembly output. Temporary hack, will be corrected later,
6062 because gplink yet does not support stack and SDCC does not
6063 yet support a type of crt0.o object to create the final binary.
6065 * Removed many lines that contain 8051 legacy code.
6066 * The code is finally placed under a 'code' directive.
6067 * Added port specific options.
6069 * _process_pragma: simplified since now we do not need *special*
6070 include file to define SFR registers. But a separate header
6071 will be needed. This will be developed later.
6072 * _pic16_parseOptions: added, parses port specific options:
6073 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6074 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6075 --preplace-udata-with=
6077 * _pic16_setDefaultOptions: modified to initialize section names,
6078 but hack is temporarly out of order since it needs improvement.
6079 * _pic16_genAssemblerPreamble: configuration words are emitted by
6080 their address instead of their name. This part is incomplete and
6081 supports only the 18Fxx2 devices. Other devices will emit an error
6082 during assembly since they do not contain the same set of config
6084 * _pic16_genIVT: is modified,
6086 * pcode.c: added definitions for some hardware registers that are needed
6088 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6089 All PCI entries are updated. Now LFSR is supported.
6090 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6091 * added pic16_newpCodeOpLit2 to support instructions with
6092 two literal arguments
6093 * pic16_pCode2str: corrected code that emits assembler instructions
6094 with two literal operands and those that have an access bit modifier
6095 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6096 this fixes a bug which caused some labels to be lost, when an
6097 assembler directive was added, i.e. banksel,
6098 * pic16_FixRegisterBanking: improved logic that causes the insertion
6100 * InlineFunction: functions that are called once, are not any more
6101 inlined. This can be a port option in the future,
6103 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6105 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6106 hold the corresponding uninitialized symbols,
6107 * pic16_allocProcessorRegister: registers have explicit marked the
6109 * pic16_allocInternalRegister: registers are explicit marked as
6111 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6112 processing list, so bit registers were lost,
6115 * ralloc.h: added field 'accessBank' and original symbol operand
6116 in register definition,
6117 * removed the field isMapped from register definition,
6119 ** Several functions have been removed from various sources:
6120 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6121 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6122 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6123 pic16_assignRelocatableRegisters
6125 ** others have been introduced:
6126 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6127 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6129 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6131 * support/scripts/inc2h.pl: changed definition of BIT_AT
6132 to emit 'sbit at' instead of 'bit at'. This was a request.
6134 PIC16 port related preliminary changes:
6135 * gen.c: prefixed function popRegFromString with
6136 pic16_ and all references to it corrected
6137 * pcode.c: all pic16_pc_* hardware registers prefixed
6138 with underscore (_),
6139 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6140 * ralloc.c: newReg(): when register is REG_SFR then
6141 set address to rIdx,
6142 pic16_allocProcessorRegister(): marks register wasUsed=0
6143 pic16_writeUsedRegs(): added a call to assign processor
6144 registers via pic16_assignFixedRegisters
6146 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6148 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6149 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6150 variables in unused register banks. Also the SSEG is placed
6151 wherever there is enough space for it, and IDATA can be anywhere
6152 in internal RAM. For now compile using -Wl-Y[stack_size].
6153 The mem file is different for this option as well, since it
6154 makes no sense of talking about DSEG lenght.
6156 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6158 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6159 in certain cases, e.g. when ROM assignment, patch provided
6160 from Albert den Haan.
6162 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
6164 Many signedness and type propagation fixes:
6165 * src/SDCCicode.c: made geniCodeCast() static
6166 replaced SPEC_ by IS_ (cosmetic)
6167 (operandOperation): fixed div and mod operation
6168 (usualBinaryConversions): added support for promotion of char
6169 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
6170 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
6171 (geniCodeAdd): an array index will stay unsigned, even if promoted

7168 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7169 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7170 If they pop r0/r1 they must be called in the opposite order than aopOp().
7171 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7172 (resp. --stack-auto), prepared for --xstack

7178 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7180 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
7181 these ports have their own __sdcc_external_start()
7183 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7185 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7186 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7187 type for bits was changed. It resulted in bit variables becoming
7188 global, which is not permitted in PIC 14 assembly output.
7190 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7192 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7194 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7196 Z80 and MCS51 linkers complaint if a public symbol is defined
7197 in more than one library module:

7205 A few small changes that speed up the peephole optimizer.
7209 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7211 Try to make the peephole optimizer smarter by maintaining
7212 an association between the assembly source code and the
7213 iCodes that originated them. Put this information to use
7214 with a new peephole rule condition "notVolatile" so that
7215 the rules can be aggressive yet still safe.
7220 * src/mcs51/peeph.def
7222 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7226 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7227 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7228 if the left or right operand symbols have the accuse flag set.
7230 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7232 Changed the type of the result of the ! (NOT) operator to char;
7233 previously it returned the same type as the source. This allows
7234 us to eliminate all the genFloatNot functions (all of its target
7235 implementations were very buggy) since !float can use the same
7238 * src/SDCCicode.c (ast2iCode): ! returns char
7239 * src/mcs51/gen.c (genNot, genNotFloat),
7240 * src/ds390/gen.c (genNot, genNotFloat),
7241 * src/z80/gen.c (genNot, genNotFloat),
7242 * src/pic/gen.c (genNot, genNotFloat),
7243 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7247 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7248 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7249 during interrupts. Ensure WSAVE is located at a shared bank address.
7250 2. Fixed page selection in some places
7251 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7252 the registers name strings.
7253 4. Fixed "signed / unsigned compare" compiler warnings.
7254 5. The PIC port manages its own allocation of the general purpose
7255 registers, but makes no attempt to reuse them. As a result when
7256 compiling it soon runs out of general purpose registers. Some
7257 additional code was added to the files pcode.c and device.c to walk
7258 through the function call tree and rename the registers so that they
7268 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7269 genPlus() & genMinus() when the result is the same as left or right

7275 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7277 Made bitfield a distinct type from bit so that bitfields
7278 convert as per ANSI C and bits retain their traditional
7279 boolean style behaviour. Implemented bitfield support in
7287 * src/ds390/gen.c: bit v bitfield split
7288 * src/z80/gen.c: New support for bitfields
7289 * support/regression/tests/bitfields.c: reenabled z80,
7292 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7294 Rules 246.x, 247.x relate to bitfields, the others speed up
7295 access to xdata mapped I/O devices.
7297 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7299 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7301 Cleaned up genPackBits and genUnpackBits and added two helper
7302 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7303 for literal assignments in genPackBits (thanks to Frieder for
7309 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7311 Fixed bug #748310 (pointer to function type mishandled when the
7312 function name is omitted). Also fixed a SIGSEGV when a function
7313 attribute (reentrant, etc) is used on a non-function or on a
7314 function but misplaced before the parameter list.
7316 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7318 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7341 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7343 Made the constant following the "interrupt" keyword optional. If
7344 omitted, the function will not automatically be given an entry
7345 in the interrupt vector table (similar to #pragma NOIV, but
7346 less syntacticly kludgy). The interrupt number is also now
7347 range checked. Also fixed a bug in the high order bit example
7354 * support/Util/SDCCerr.c
7355 * support/Util/SDCCerr.h
7358 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7361 * src/SDCCicode.c (operandOperation): rewritten some ops
7362 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7363 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7365 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7366 be re-activated by defining REDUCE_LITERALS)
7367 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7368 unsigned, but are signed by default
7369 * src/SDCCval.c (constVal): rearranged
7370 * src/SDCCval.c (valMod): preliminary fix
7371 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7823 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7824 the regression tests I'm not brave enough to enable 245.b, 245.c
7825 * doc/sdccman.lyx: added latex preamble for hyperref package.
7826 Using pdflatex this will give you a hyperlinked pdf file with
7827 bookmarks. (prepend '%' before /usepackage if this breaks something)

7868 it can be defined with CFLAGS when running configure
7869 * src/SDCCmain.c: fixed compiling + linking with object files
7871 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7874 added --disable-pic16-port
7875 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7876 * src/SDCCmain.c: linkOptions is changed to set *,
7877 added if/endif conditional macros to remove options help
7878 messages from optionsTable when a port is not configured, added
7879 support for the PIc16 port in the ports table, when executing
7880 the compiler with no port specified on command line, a default
7881 port is selected with the new macro DEFAULT_PORT which is
7882 defined in port.h, in setDefaultOptions() linkOptions is removed
7883 from initialization assignment, since now it is a set,
7884 parseCmdLine uses setParseWithComma for linkOptions, in
7885 linkEdit() linkOptions are accessed with new function indexSet()
7886 which returns the i'th item of a set variable. See SDCCset.c, in
7887 linkEdit() when calling buildCmdLine(), added linkOptions as
7888 last argument. Now users can pass arguments to gplink via the
7889 -Wl option, main() uses pic16glue() to glue up pic16 programs

7901 * src/pic16/glue.c: commented out some error producing lines
7902 * src/pic16/main.c: __config directives are commented out to stop
7903 gpasm complaining and test the linkage with gplink, _linkCmd and
7904 _asmCmd changed to be more gplink and gpasm friendly
7905 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7906 produced an error when parsed, peep rule 12 is added to utilize
7907 movff, but it is commented out since the pCode does not support
7908 yet a command with 2 address arguments
7910 2003-05-18 <johan AT balder>
7912 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7913 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7937 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7939 2003-05-11 Borut Razem <borut.razem AT siol.net>
7941 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7942 the path of bin directory, so that PATH is the only env. variable, which has to be set
7943 in case of standard installation.
7944 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8973 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8975 * in \sdcc\as\mcs51\ changed these files in order to create an
8976 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8977 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8978 following files to include the previous two files: aslink.dsp,
8979 Makefile.aslink, Makefile.bcc, and Makefile.in.
8981 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8982 .adb instead of .cdb
8984 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8986 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8987 value from option --iram-size.
8989 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8991 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8994 2002-09-18 <wiml AT hhhh.org>
8996 * SDCClrange.h: exposed setFromRange() and setToRange()
8997 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8998 packRegsForAccUse() (bug 542397)
8999 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9000 multiple times and emitting the fetch operations more than once
9001 added aopGetUsesAcc() function to allow binary operators to
9002 fetch their operands in the correct order; made genMinus() emit
9003 compact code for X = LITERAL - Y
9005 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9006 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9007 sprintf() in line 1267.
9009 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9010 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9013 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9014 Changes to aslink (All the changes are marked with 'JCF'):
9016 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9019 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9020 area BSEG. Also moves, if possible, the DATA area down into the internal
9021 ram so more space is available.
9023 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9026 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9027 not bytes. Function summary() which creates a memory usage summary
9028 file with extension .mem. Reports of overlaping stack and small stack
9029 size. If the space for the stack is less than 16 bytes aslink trows a
9032 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9033 the 8051. Option 'y' for memory summary output file.
9035 Changes to sdcc (All the changes are marked with 'JCF'):
9037 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9039 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9040 overlaying area for it (uses RegBankUsed[4]).
9042 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9043 bank zero as used by default. By default aslink locates the stack
9044 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9045 the creation of the .mem file. Delegates the allocation of data area
9046 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9047 the begining of the stack area to aslink.
9049 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9050 glue() in SDCCglue.c creates an area for it.
9052 2002-09-03 Borut Razem <borut.razem AT siol.net>
9053 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9054 sdcc/src/pic/glue.c:
9055 introduced atexit() handler for teporay files removal in case of
9056 errors, assertions, ...
9058 2002-08-29 Borut Razem <borut.razem AT siol.net>
9059 * sdcc/support/cpp2/auto-host_vc_in.h:
9060 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9061 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9062 Maybe there is a similar problem with BORLANDC? It should be checked!
9064 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9065 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9066 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9067 was not executed, and the compiler (cl) launched a warning:
9068 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9070 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9071 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9073 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

9080 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9081 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9082 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9083 - added Release configuration in VS projects
9084 - review of compiler an linker options
9085 - VC .exe files are generated in bin_vc directory, not to interfere
9086 with binaries generated from other projects (cygwin, mingw, bcc ...)
9088 * sdcc/src/yacc.dsp: added
9090 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9091 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9092 and insert the version number definitions from .version
9094 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9096 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9100 removed from CVS, generated automatically
9102 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9103 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9105 2002-08-11 Borut Razem <borut.razem AT siol.net>
9106 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9108 2002-08-10 Borut Razem <borut.razem AT siol.net>
9109 * src/SDCCmain.c (main):
9110 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9111 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9112 The consequence was that some temporary files were not removed.
9115 unification of code in functions tempfilename() and tempfile():
9116 function tempnam() is defined in Visual Studio 6.0 and .NET
9118 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9120 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9121 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9122 - removed compiler command line option /WX: Treats all warnings as errors
9123 - update a list of source files, included into the project
9125 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9126 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9127 changed project type to Generic Project so that can be correcly converted to VS.NET project
9129 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9131 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9133 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9135 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9136 added return 0 statements after assert() to make compiler happy
9138 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9139 added newline in the def file to keep MSC compiler satisfied
9141 * sdcc/src/z80/gen.c:
9142 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9143 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9144 - solved MSC error in function aopDump()
9146 * sdcc_vc.h: define PREFIX as "\\sdcc"
9148 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9200 Initialized the new field char *Processor field to NULL in all ports
9203 Compiler generated registers for interrupt context saving
9204 were not getting allocated.
9206 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9209 Fixed left shift. Will promote the left side of a left shift
9210 if a) left shifting more than size of operand or b) when assigned
9211 to something size > size of left side
9213 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9321 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9323 * sdcc/src/SDCCloop.c:
9324 Previous fix was not good. basic blocks that have "break" or "return" are
9325 not really partof a loop , but live ranges used in these blocks should
9326 be live thru the entire loop, so set partOfLoop but don't add them to
9329 2002-02-21 <johan AT FRIJA>
9331 * src/SDCCcse.c: fixed bug #514308
9333 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
