1828 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1829 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1830 always available in leading double underscore form. The C99 support is
1831 mostly missing, but it's a start.
1832 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1911 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1913 * device/lib/printf_large.c: removed inline assembly for portability and
1914 readability. Use printf_fast if speed or size are more important.
1915 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1916 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1918 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1920 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1921 prevent compiler warning
1923 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1925 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1926 moved to level 0 and declared as static. Also they are explicit
1927 placed in access bank. This was necessery because some times they
1928 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1929 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1930 optimizations. Currently only compare to unsigned char is implemented,
1931 * src/pic16/gen.c: added fReturnIdx array,
1932 * (struct resolvedIfx) is moved to gen.h and made public,
1933 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1934 * (aopForSym): added an optimization to directly store in stack of
1935 the operand of a SEND iCode,
1936 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1937 but as registers instead (AOP_REG) using the fReturnIdx array,
1938 * (pic16_freeAsmop): remove the freed register from the
1939 _G.sregsAlloc field,
1940 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1941 a compare of 'WREG',
1942 * (pic16_popGetTempRegCond): changed function prototype, now
1943 function takes also a bitVector argument v which holds the current
1944 set of registers that are allocated for stack access by aopForSym,
1945 registers allocated in aopForSym for accessing stack symbols are not
1946 any more part of the functions usedRegs field,
1947 * (genCall): some times aopOp is called for a stack variable to be
1948 send, aopForSym might perform the push, if this is true make sure
1949 that genCall doesn't push the variable twice by testing _G.resDirect,
1950 * (genFunction): changed testing for unspecified interrupt number
1951 from 256 to INTNO_UNSPEC,
1952 * modified selection scheme of frame pointer generation. Previously
1953 if function did use local registers a frame pointer was generated,
1954 now a frame pointer is generated only if function has arguments
1955 (that need PLUSW2 register access), or has stack arguments, or the
1956 compiler is not instructed to omit the frame pointer,
1957 * (genEndFunction): before restoring local registers that were saved
1958 in the function preamble, also restore the registers that *might*
1959 have been allocated for stack access,
1960 * (genRet): removed some old comments,
1961 * (genCmp, the active (RN's) version): added a call to the
1962 pic16_genCmp_special function to perform the compare with a more
1963 robust and optimized way,
1964 * (genInline): a feature has been added in inline code generation,
1965 which allows a wildcard variable substitution when writing inline
1966 assembly. Code is incomplete and experimental therefore undocumented,
1967 * (genCast): changed order of aopOp for result and right to allow
1968 aopForSym to directly load the result if possible,
1969 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1970 perform an optimized compare on some selected special occasions,
1971 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1972 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1973 generate an IVT any more,
1974 * src/pic16/main.c (pic16_optionsTable): added command line option
1976 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1977 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1979 * src/pic16/NOTES: Raphael Neider added in list of active developers
1980 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1981 jumptable_end to prevent bug #,
1982 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1983 inCond and outCond fields,
1984 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1985 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1986 turn off register spilling,
1987 * (packRegsForOneUse): synced with other ports' versions although it
1988 is not used currently,
1989 * (pic16_packRegisters): added an optimization while reading
1990 structure bitfields, some registers may be saved (malloc code is
1991 decreased by 80 bytes)
1993 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1995 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1996 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1997 this can be optimized more?
1999 2005-03-10 Raphael Neider <rneider AT web.de>
2001 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2002 genNearPointerGet): (hopefully) fixed access to bitfields via
2003 pointers (p->bitN = x; and x = p->bitN; failed)

2637 Adding support for replacing ljmps with sjmps in jumptables
2638 generated for switch statements. For now you need to set the
2639 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2640 Now 4 algorithms for mcs51 jumptable generation are used:
2641 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2642 addresses loaded pc-relative for up to 112 cases and stack-pushing
2643 target addresses loaded with offset from dptr for up to 256 cases.

2669 Large cummulative patch for pic16 port.
2670 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2671 to call when a stack overflow occurs,
2672 * (malloc.h): added CVS Id tag,
2673 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2675 * added libc directory. The current version of LibC contains string
2676 functions, ctype functions and macros and some functions of the
2677 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2678 be extensively tested in the future. Standard disclaimer here.
2679 Library is not automatically build yet. But one can build it by
2680 invoking 'make' inside the libc directory.
2681 * added ADC library under libio. Preliminary version yet.
2683 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2690 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2691 * (pic16_storeForReturn): optimized return of 0,
2692 * (genCmp): experimental code for new genCmp which uses PIC18's
2693 special compare&skip instructions. Initial tests fail some times
2694 with variables grater than 1 byte in size, so new code is disabled,
2695 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2697 * (genCast): began a fix to optimize the casting of a bit to another
2698 bit, now assigning a bitfield to another bitfield will fail, sorry,
2699 * src/pic16/main.c: disabled the use of lr-support feature,
2700 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2701 * added some function prototypes, added function _debugf prototype,

2703 bits with offset (case PO_GPR_BIT),
2704 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2706 * (isBankInstruction): modified to return 0 for no banking instruction,
2707 and 1 for banking instruction,
2708 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2709 caused stop processing pCodes after a inline assembly block,
2710 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2711 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2712 registers when it shouldn't,
2713 * src/pic16/ralloc.c (allocReg): add preliminary support for
2714 supporting a limited set of temporary registers,
2716 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2718 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2719 genDataPointerSet): ensure assignments always copy in MSB to LSB
2721 (loadRegFromAop): recognize CLRH optimization,
2722 (genFunction): optimize RECEIVE iCodes in reentrant functions
2724 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2726 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2740 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2742 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5688 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5691 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5692 strtof is not part of C89 and isn't included with Mac OS X.
5694 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5718 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
5721 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5723 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5724 loaded with the linker search paths (-L arguments) and the libraries
5725 to be linked with the current source (-l arguments). Changes
5726 currently will affect only the pic16 port.
5727 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5728 include path the port specific paths and port specific libraries,
5729 * gplink command now contains the $3 argument,
5730 * src/pic16/device.h,
5731 * src/pic16/device.c,: structure PIC_device is made public and
5732 renamed to PIC16_device, the same for variable Pics which is renamed
5733 to Pics16. Updated all references to them.
5734 * src/pic16/glue.c (pic16glue): corrected bug with code
5735 initialization which bypassed the variable initializations block.
5737 * device/lib/pic16/Makefile.rules: removed --penable-stack from

5745 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5747 Documenting changes from previous commits.
5748 * configure.in (version 1.56),
5749 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5750 when generating output files to configure the pic16 library,
5751 but now I've commented it out, since gputils aren't installed in the
5752 SF compile farm, so library won't compile
5754 * device/lib/Makefile.in (version 1.56): initially I've added in
5755 target 'all' the prerequestive 'model-pic16' so it compiled the
5756 pic16 library, but now I've commented it out for the same reasons
5758 * added targets 'model-pic16' and 'objects-pic16' to compile the
5760 * added target 'port-specific-objects-pic16' to handle the
5761 generated libraries and copy them into the build/ directory
5762 * added target 'clean-intermediate-pic16' to clean intermediate
5763 files into pic16 directory
5764 * in target 'installdirs' added line to create directory pic16 in
5765 the installation path
5767 * device/include/Makefile.in (version 1.11): in target 'install'
5768 added lines to copy all header files to installation path,
5769 * in target 'installdirs' added line create directory for pic16
5770 headers in the installation path
5772 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5785 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5786 option so that it actually works. Made it specific to the z80, since
5787 the gbz80 doesn't have these kinds of I/O ports.
5789 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5791 * device/include/z180.h,

5804 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5806 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5807 changed interrupt vector table generation to only emit declared vectors.
5808 * device/include/Makefile.in: added missing backslash
5809 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5811 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5813 Mainly changes to support compilation of the device libraries
5814 * src/pic16/device.c: stack is allocated via symbol and not
5815 via literal number. The symbol is placed in the corresponding
5816 position of the data ram
5817 * (pic16_dump_section): relocatable and absolute uninitialized
5818 data are now emitted in sorted order to reduce section naming,
5819 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5820 weren't marked as being in the access bank,
5822 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5824 Added portion of GNU PIC Library under the directory
5825 device/include/pic16 and device/lib/pic16. These files
5826 contain the declarations of SFRs for the PIC18Fxx2 devices.
5827 The directory is initialized via configure from toplevel.
5829 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5831 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5832 the spilllocations to be compared correctly
5834 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5836 * src/SDCCast.c (decorateType): fixed bug introduced today
5838 2004-01-12 Borut Razem <borut.razem AT siol.net>
5840 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5843 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5845 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5846 in simpler and even better code
5848 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5850 * src/SDCCicode.c (operandOperation): fixed bug #874819

5854 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5856 * doc/sdccman.lyx: Moved and added some sections, small changes
5857 all over. Telling LaTeX to be less strict with word spacing
5858 to better keep the right margin. Changed some notes about
5859 maintainance of the ports in section 3.2.1 - is it OK like this?
5861 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5863 SDCC source changes:
5864 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5897 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5898 UPPER for immediate operands,
5899 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5901 * src/pic16/peeph.def: all peepholes with movff are commented out,
5902 because there is a problem in the pcode peep optimizer,
5903 * src/pic16/ralloc.c: the register allocator can now reuse local
5904 function symbols for another function. This saves register usage.
5905 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5907 Added file src/pic16/NOTES with information about program writing on
5908 the current port version.

5917 * src/SDCCmain.c : fixed #872250: -l command line defined library
5918 files are scanned before standard library files
5920 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5937 gen51Code): more efficient parameter receive for --model-large
5940 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5943 * src/z80/main.c: added missed needLinkerScript flags (more than
5944 one port structure defined in these file)
5945 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5961 needLinkerScript flag
5963 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5964 * src/pic/glue.c: added variable udata_section_name to
5965 override default uninitialized data segment definition for
5966 devices only with SHAREBANK memory (reported from Erik Epetrich)
5967 * (pic14emitOverlay): modified to emit a commented overlay segment
5968 directive when no overlay data exist
5969 * (picglue): modified to emit uninitialized data segment
5970 according to udata_section_name

5975 arguments via -W option
5976 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5977 object file from '.rel' to '.o' in port->linker structure,
5978 changed size of fptr from 2 to 3 in port structure
5980 2004-01-07 Borut Razem <borut.razem AT siol.net>
5982 * support/scripts/sdcc.nsi: update PATH
5983 * support/scripts/sdcc.ico: craeted
5985 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
5987 * device/include/Makefile.in: fix install
5988 * doc/Makefile: fix install
5990 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5992 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5994 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5996 include information about variables allocated to the overlay
5999 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6001 * as/mcs51/lkmain.c: Help about -Y option

6010 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6011 LEFT_OP (left shift)
6013 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6015 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6016 (default behaviour).
6018 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6020 A python script to validate compiler diagnostic messages. It can be
6021 used to verify that sdcc complains about bad c source code and
6022 gives a good location of the error.
6023 * support/valdiag/Makefile,
6024 * support/valdiag/valdiag.py,
6025 * support/valdiag/tests/*
6027 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6029 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6038 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6040 * src/common.h: added ifndef/define/endif macros
6041 around the header file.
6042 Bug reported from Jesus Calvino-Fraga
6044 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6046 * sdcc.spec: updated
6047 * device/include/Makefile.in: don't install CVS directories
6048 * device/lib/Makefile.in: added removal of CVS directories after install
6049 * doc/Makefile: fixed install, added local_icons
6050 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6051 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6052 * src/ds390/gen.c (genRightShift): fixed bug #870788
6053 * src/SDCCast.c (decorateType): fixed bug #870781
6055 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6057 PIC16 port related changes:
6058 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6059 added variable stackPos,
6061 * gen.c: genCall, assignResultValue: added support for
6062 pushing/retrieving function parameters to/from stack,
6063 genFunction,genEndFunction: setup stack frame for the
6065 genAddrOf: will be changed according to bug 863624
6067 * added files genutils.c and genutils.h which contain gen*
6068 debugged and optimised functions extracted from gen.c
6070 * glue.c: added variable 'externs' which holds extern symbols,
6071 pic16emitRegularMap: is modified to properly handle relocatable
6072 symbols under the new scheme,
6073 pic16createInterruptVect: is modified
6074 pic16printPublics: is modified to emit 'global' assembler directives,
6075 added pic16_printExterns to print extern symbols,
6076 pic16glue: initializes stack/frame pointer in the beginning of
6077 the assembly output. Temporary hack, will be corrected later,
6078 because gplink yet does not support stack and SDCC does not
6079 yet support a type of crt0.o object to create the final binary.
6081 * Removed many lines that contain 8051 legacy code.
6082 * The code is finally placed under a 'code' directive.
6083 * Added port specific options.
6085 * _process_pragma: simplified since now we do not need *special*
6086 include file to define SFR registers. But a separate header
6087 will be needed. This will be developed later.
6088 * _pic16_parseOptions: added, parses port specific options:
6089 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6090 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6091 --preplace-udata-with=
6093 * _pic16_setDefaultOptions: modified to initialize section names,
6094 but hack is temporarly out of order since it needs improvement.
6095 * _pic16_genAssemblerPreamble: configuration words are emitted by
6096 their address instead of their name. This part is incomplete and
6097 supports only the 18Fxx2 devices. Other devices will emit an error
6098 during assembly since they do not contain the same set of config
6100 * _pic16_genIVT: is modified,
6102 * pcode.c: added definitions for some hardware registers that are needed
6104 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6105 All PCI entries are updated. Now LFSR is supported.
6106 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6107 * added pic16_newpCodeOpLit2 to support instructions with
6108 two literal arguments
6109 * pic16_pCode2str: corrected code that emits assembler instructions
6110 with two literal operands and those that have an access bit modifier
6111 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6112 this fixes a bug which caused some labels to be lost, when an
6113 assembler directive was added, i.e. banksel,
6114 * pic16_FixRegisterBanking: improved logic that causes the insertion
6116 * InlineFunction: functions that are called once, are not any more
6117 inlined. This can be a port option in the future,
6119 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6121 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6122 hold the corresponding uninitialized symbols,
6123 * pic16_allocProcessorRegister: registers have explicit marked the
6125 * pic16_allocInternalRegister: registers are explicit marked as
6127 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6128 processing list, so bit registers were lost,
6131 * ralloc.h: added field 'accessBank' and original symbol operand
6132 in register definition,
6133 * removed the field isMapped from register definition,
6135 ** Several functions have been removed from various sources:
6136 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6137 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6138 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6139 pic16_assignRelocatableRegisters
6141 ** others have been introduced:
6142 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6143 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6145 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6147 * support/scripts/inc2h.pl: changed definition of BIT_AT
6148 to emit 'sbit at' instead of 'bit at'. This was a request.
6150 PIC16 port related preliminary changes:
6151 * gen.c: prefixed function popRegFromString with
6152 pic16_ and all references to it corrected
6153 * pcode.c: all pic16_pc_* hardware registers prefixed
6154 with underscore (_),
6155 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6156 * ralloc.c: newReg(): when register is REG_SFR then
6157 set address to rIdx,
6158 pic16_allocProcessorRegister(): marks register wasUsed=0
6159 pic16_writeUsedRegs(): added a call to assign processor
6160 registers via pic16_assignFixedRegisters
6162 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6164 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6165 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6166 variables in unused register banks. Also the SSEG is placed
6167 wherever there is enough space for it, and IDATA can be anywhere
6168 in internal RAM. For now compile using -Wl-Y[stack_size].
6169 The mem file is different for this option as well, since it
6170 makes no sense of talking about DSEG lenght.
6172 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6174 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7174 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7175 before instructions that use the _STATUS register
7177 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7179 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7180 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7181 fetching of the pointer
7182 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7183 copied from genNearPointerSet()
7184 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7185 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7186 If they pop r0/r1 they must be called in the opposite order than aopOp().
7187 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7188 (resp. --stack-auto), prepared for --xstack

7199 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7201 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7202 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7203 type for bits was changed. It resulted in bit variables becoming
7204 global, which is not permitted in PIC 14 assembly output.
7206 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7208 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7210 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7212 Z80 and MCS51 linkers complaint if a public symbol is defined

7221 A few small changes that speed up the peephole optimizer.
7225 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7227 Try to make the peephole optimizer smarter by maintaining
7228 an association between the assembly source code and the
7229 iCodes that originated them. Put this information to use
7230 with a new peephole rule condition "notVolatile" so that
7231 the rules can be aggressive yet still safe.
7236 * src/mcs51/peeph.def
7238 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7242 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7243 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7244 if the left or right operand symbols have the accuse flag set.
7246 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7248 Changed the type of the result of the ! (NOT) operator to char;
7249 previously it returned the same type as the source. This allows
7250 us to eliminate all the genFloatNot functions (all of its target
7251 implementations were very buggy) since !float can use the same
7254 * src/SDCCicode.c (ast2iCode): ! returns char

7256 * src/ds390/gen.c (genNot, genNotFloat),
7257 * src/z80/gen.c (genNot, genNotFloat),
7258 * src/pic/gen.c (genNot, genNotFloat),

7263 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7264 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7265 during interrupts. Ensure WSAVE is located at a shared bank address.
7266 2. Fixed page selection in some places
7267 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7268 the registers name strings.
7269 4. Fixed "signed / unsigned compare" compiler warnings.
7270 5. The PIC port manages its own allocation of the general purpose
7271 registers, but makes no attempt to reuse them. As a result when
7272 compiling it soon runs out of general purpose registers. Some
7273 additional code was added to the files pcode.c and device.c to walk
7274 through the function call tree and rename the registers so that they
7284 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7285 genPlus() & genMinus() when the result is the same as left or right

7291 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7293 Made bitfield a distinct type from bit so that bitfields
7294 convert as per ANSI C and bits retain their traditional
7295 boolean style behaviour. Implemented bitfield support in
7303 * src/ds390/gen.c: bit v bitfield split
7304 * src/z80/gen.c: New support for bitfields
7305 * support/regression/tests/bitfields.c: reenabled z80,
7308 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7310 Rules 246.x, 247.x relate to bitfields, the others speed up
7311 access to xdata mapped I/O devices.
7313 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7315 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7317 Cleaned up genPackBits and genUnpackBits and added two helper
7318 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7319 for literal assignments in genPackBits (thanks to Frieder for
7325 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7327 Fixed bug #748310 (pointer to function type mishandled when the
7328 function name is omitted). Also fixed a SIGSEGV when a function
7329 attribute (reentrant, etc) is used on a non-function or on a
7330 function but misplaced before the parameter list.
7332 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7334 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7357 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7359 Made the constant following the "interrupt" keyword optional. If
7360 omitted, the function will not automatically be given an entry
7361 in the interrupt vector table (similar to #pragma NOIV, but
7362 less syntacticly kludgy). The interrupt number is also now
7363 range checked. Also fixed a bug in the high order bit example

7377 * src/SDCCicode.c (operandOperation): rewritten some ops
7378 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7379 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7381 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7382 be re-activated by defining REDUCE_LITERALS)
7383 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7384 unsigned, but are signed by default
7385 * src/SDCCval.c (constVal): rearranged
7386 * src/SDCCval.c (valMod): preliminary fix
7387 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7892 * src/SDCCmain.c: linkOptions is changed to set *,
7893 added if/endif conditional macros to remove options help
7894 messages from optionsTable when a port is not configured, added
7895 support for the PIc16 port in the ports table, when executing
7896 the compiler with no port specified on command line, a default
7897 port is selected with the new macro DEFAULT_PORT which is
7898 defined in port.h, in setDefaultOptions() linkOptions is removed
7899 from initialization assignment, since now it is a set,
7900 parseCmdLine uses setParseWithComma for linkOptions, in
7901 linkEdit() linkOptions are accessed with new function indexSet()
7902 which returns the i'th item of a set variable. See SDCCset.c, in
7903 linkEdit() when calling buildCmdLine(), added linkOptions as
7904 last argument. Now users can pass arguments to gplink via the
7905 -Wl option, main() uses pic16glue() to glue up pic16 programs

7917 * src/pic16/glue.c: commented out some error producing lines
7918 * src/pic16/main.c: __config directives are commented out to stop
7919 gpasm complaining and test the linkage with gplink, _linkCmd and
7920 _asmCmd changed to be more gplink and gpasm friendly
7921 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7922 produced an error when parsed, peep rule 12 is added to utilize
7923 movff, but it is commented out since the pCode does not support
7924 yet a command with 2 address arguments
7926 2003-05-18 <johan AT balder>
7928 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7929 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7955 2003-05-11 Borut Razem <borut.razem AT siol.net>
7957 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7958 the path of bin directory, so that PATH is the only env. variable, which has to be set
7959 in case of standard installation.

8989 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8991 * in \sdcc\as\mcs51\ changed these files in order to create an
8992 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8993 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8994 following files to include the previous two files: aslink.dsp,
8995 Makefile.aslink, Makefile.bcc, and Makefile.in.
8997 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8998 .adb instead of .cdb
9000 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9002 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9003 value from option --iram-size.
9005 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9007 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9010 2002-09-18 <wiml AT hhhh.org>
9012 * SDCClrange.h: exposed setFromRange() and setToRange()
9013 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9014 packRegsForAccUse() (bug 542397)
9015 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9016 multiple times and emitting the fetch operations more than once
9017 added aopGetUsesAcc() function to allow binary operators to
9018 fetch their operands in the correct order; made genMinus() emit
9019 compact code for X = LITERAL - Y
9021 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9022 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9023 sprintf() in line 1267.
9025 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9026 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9029 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9030 Changes to aslink (All the changes are marked with 'JCF'):
9032 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9035 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9036 area BSEG. Also moves, if possible, the DATA area down into the internal
9037 ram so more space is available.
9039 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9042 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9043 not bytes. Function summary() which creates a memory usage summary
9044 file with extension .mem. Reports of overlaping stack and small stack
9045 size. If the space for the stack is less than 16 bytes aslink trows a
9048 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9049 the 8051. Option 'y' for memory summary output file.
9051 Changes to sdcc (All the changes are marked with 'JCF'):
9053 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9055 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9056 overlaying area for it (uses RegBankUsed[4]).
9058 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9059 bank zero as used by default. By default aslink locates the stack
9060 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9061 the creation of the .mem file. Delegates the allocation of data area
9062 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9063 the begining of the stack area to aslink.
9065 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9066 glue() in SDCCglue.c creates an area for it.
9068 2002-09-03 Borut Razem <borut.razem AT siol.net>
9069 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9070 sdcc/src/pic/glue.c:
9071 introduced atexit() handler for teporay files removal in case of
9072 errors, assertions, ...
9074 2002-08-29 Borut Razem <borut.razem AT siol.net>
9075 * sdcc/support/cpp2/auto-host_vc_in.h:
9076 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9077 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9078 Maybe there is a similar problem with BORLANDC? It should be checked!
9080 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9081 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9082 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9083 was not executed, and the compiler (cl) launched a warning:
9084 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9086 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9087 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

9094 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9095 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9096 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9097 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9098 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9099 - added Release configuration in VS projects
9100 - review of compiler an linker options
9101 - VC .exe files are generated in bin_vc directory, not to interfere
9102 with binaries generated from other projects (cygwin, mingw, bcc ...)
9104 * sdcc/src/yacc.dsp: added
9106 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9107 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9108 and insert the version number definitions from .version
9110 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9112 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9122 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9124 2002-08-10 Borut Razem <borut.razem AT siol.net>
9125 * src/SDCCmain.c (main):
9126 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9127 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9128 The consequence was that some temporary files were not removed.
9131 unification of code in functions tempfilename() and tempfile():
9132 function tempnam() is defined in Visual Studio 6.0 and .NET
9134 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9136 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9137 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

9152 added return 0 statements after assert() to make compiler happy
9154 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9155 added newline in the def file to keep MSC compiler satisfied
9157 * sdcc/src/z80/gen.c:
9158 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9159 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9160 - solved MSC error in function aopDump()
9162 * sdcc_vc.h: define PREFIX as "\\sdcc"
9164 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9216 Initialized the new field char *Processor field to NULL in all ports
9219 Compiler generated registers for interrupt context saving
9220 were not getting allocated.
9222 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9225 Fixed left shift. Will promote the left side of a left shift
9226 if a) left shifting more than size of operand or b) when assigned
9227 to something size > size of left side
9229 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9339 * sdcc/src/SDCCloop.c:
9340 Previous fix was not good. basic blocks that have "break" or "return" are
9341 not really partof a loop , but live ranges used in these blocks should
9342 be live thru the entire loop, so set partOfLoop but don't add them to
9345 2002-02-21 <johan AT FRIJA>
