1822 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1823 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1824 always available in leading double underscore form. The C99 support is

1905 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1907 * device/lib/printf_large.c: removed inline assembly for portability and
1908 readability. Use printf_fast if speed or size are more important.
1909 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1910 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1912 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1914 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1915 prevent compiler warning
1917 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1919 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1920 moved to level 0 and declared as static. Also they are explicit
1921 placed in access bank. This was necessery because some times they
1922 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1923 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1924 optimizations. Currently only compare to unsigned char is implemented,
1925 * src/pic16/gen.c: added fReturnIdx array,
1926 * (struct resolvedIfx) is moved to gen.h and made public,
1927 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1928 * (aopForSym): added an optimization to directly store in stack of
1929 the operand of a SEND iCode,
1930 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1931 but as registers instead (AOP_REG) using the fReturnIdx array,
1932 * (pic16_freeAsmop): remove the freed register from the
1933 _G.sregsAlloc field,
1934 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1935 a compare of 'WREG',
1936 * (pic16_popGetTempRegCond): changed function prototype, now
1937 function takes also a bitVector argument v which holds the current
1938 set of registers that are allocated for stack access by aopForSym,
1939 registers allocated in aopForSym for accessing stack symbols are not
1940 any more part of the functions usedRegs field,
1941 * (genCall): some times aopOp is called for a stack variable to be
1942 send, aopForSym might perform the push, if this is true make sure
1943 that genCall doesn't push the variable twice by testing _G.resDirect,
1944 * (genFunction): changed testing for unspecified interrupt number
1945 from 256 to INTNO_UNSPEC,
1946 * modified selection scheme of frame pointer generation. Previously
1947 if function did use local registers a frame pointer was generated,
1948 now a frame pointer is generated only if function has arguments
1949 (that need PLUSW2 register access), or has stack arguments, or the
1950 compiler is not instructed to omit the frame pointer,
1951 * (genEndFunction): before restoring local registers that were saved
1952 in the function preamble, also restore the registers that *might*
1953 have been allocated for stack access,
1954 * (genRet): removed some old comments,
1955 * (genCmp, the active (RN's) version): added a call to the
1956 pic16_genCmp_special function to perform the compare with a more
1957 robust and optimized way,
1958 * (genInline): a feature has been added in inline code generation,
1959 which allows a wildcard variable substitution when writing inline
1960 assembly. Code is incomplete and experimental therefore undocumented,
1961 * (genCast): changed order of aopOp for result and right to allow
1962 aopForSym to directly load the result if possible,
1963 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1964 perform an optimized compare on some selected special occasions,
1965 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1966 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1967 generate an IVT any more,
1968 * src/pic16/main.c (pic16_optionsTable): added command line option
1970 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1971 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1973 * src/pic16/NOTES: Raphael Neider added in list of active developers
1974 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1975 jumptable_end to prevent bug #,
1976 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1977 inCond and outCond fields,
1978 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1979 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1980 turn off register spilling,
1981 * (packRegsForOneUse): synced with other ports' versions although it
1982 is not used currently,
1983 * (pic16_packRegisters): added an optimization while reading
1984 structure bitfields, some registers may be saved (malloc code is
1985 decreased by 80 bytes)
1987 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1989 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1990 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1991 this can be optimized more?
1993 2005-03-10 Raphael Neider <rneider AT web.de>
1995 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1996 genNearPointerGet): (hopefully) fixed access to bitfields via
1997 pointers (p->bitN = x; and x = p->bitN; failed)
1999 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2631 Adding support for replacing ljmps with sjmps in jumptables
2632 generated for switch statements. For now you need to set the
2633 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2634 Now 4 algorithms for mcs51 jumptable generation are used:
2635 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2636 addresses loaded pc-relative for up to 112 cases and stack-pushing
2637 target addresses loaded with offset from dptr for up to 256 cases.
2639 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

2664 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2665 to call when a stack overflow occurs,
2666 * (malloc.h): added CVS Id tag,
2667 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2669 * added libc directory. The current version of LibC contains string
2670 functions, ctype functions and macros and some functions of the
2671 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2672 be extensively tested in the future. Standard disclaimer here.
2673 Library is not automatically build yet. But one can build it by
2674 invoking 'make' inside the libc directory.
2675 * added ADC library under libio. Preliminary version yet.
2677 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2684 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2685 * (pic16_storeForReturn): optimized return of 0,
2686 * (genCmp): experimental code for new genCmp which uses PIC18's
2687 special compare&skip instructions. Initial tests fail some times
2688 with variables grater than 1 byte in size, so new code is disabled,
2689 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2691 * (genCast): began a fix to optimize the casting of a bit to another
2692 bit, now assigning a bitfield to another bitfield will fail, sorry,
2693 * src/pic16/main.c: disabled the use of lr-support feature,
2694 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2697 bits with offset (case PO_GPR_BIT),
2698 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2700 * (isBankInstruction): modified to return 0 for no banking instruction,
2701 and 1 for banking instruction,
2702 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2703 caused stop processing pCodes after a inline assembly block,
2704 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2705 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2706 registers when it shouldn't,
2707 * src/pic16/ralloc.c (allocReg): add preliminary support for
2708 supporting a limited set of temporary registers,
2710 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2712 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2713 genDataPointerSet): ensure assignments always copy in MSB to LSB
2715 (loadRegFromAop): recognize CLRH optimization,
2716 (genFunction): optimize RECEIVE iCodes in reentrant functions
2718 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2720 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2734 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2736 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5715 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5717 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5718 loaded with the linker search paths (-L arguments) and the libraries
5719 to be linked with the current source (-l arguments). Changes
5720 currently will affect only the pic16 port.
5721 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5722 include path the port specific paths and port specific libraries,
5723 * gplink command now contains the $3 argument,
5724 * src/pic16/device.h,
5725 * src/pic16/device.c,: structure PIC_device is made public and
5726 renamed to PIC16_device, the same for variable Pics which is renamed
5727 to Pics16. Updated all references to them.
5728 * src/pic16/glue.c (pic16glue): corrected bug with code
5729 initialization which bypassed the variable initializations block.

5739 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5741 Documenting changes from previous commits.
5742 * configure.in (version 1.56),
5743 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5744 when generating output files to configure the pic16 library,
5745 but now I've commented it out, since gputils aren't installed in the
5746 SF compile farm, so library won't compile
5748 * device/lib/Makefile.in (version 1.56): initially I've added in
5749 target 'all' the prerequestive 'model-pic16' so it compiled the
5750 pic16 library, but now I've commented it out for the same reasons
5752 * added targets 'model-pic16' and 'objects-pic16' to compile the
5754 * added target 'port-specific-objects-pic16' to handle the
5755 generated libraries and copy them into the build/ directory
5756 * added target 'clean-intermediate-pic16' to clean intermediate
5757 files into pic16 directory
5758 * in target 'installdirs' added line to create directory pic16 in
5759 the installation path
5761 * device/include/Makefile.in (version 1.11): in target 'install'
5762 added lines to copy all header files to installation path,
5763 * in target 'installdirs' added line create directory for pic16
5764 headers in the installation path

5779 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5780 option so that it actually works. Made it specific to the z80, since
5781 the gbz80 doesn't have these kinds of I/O ports.
5783 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5785 * device/include/z180.h,

5798 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5800 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5801 changed interrupt vector table generation to only emit declared vectors.

5807 Mainly changes to support compilation of the device libraries
5808 * src/pic16/device.c: stack is allocated via symbol and not
5809 via literal number. The symbol is placed in the corresponding
5810 position of the data ram
5811 * (pic16_dump_section): relocatable and absolute uninitialized
5812 data are now emitted in sorted order to reduce section naming,
5813 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5814 weren't marked as being in the access bank,
5816 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5818 Added portion of GNU PIC Library under the directory
5819 device/include/pic16 and device/lib/pic16. These files
5820 contain the declarations of SFRs for the PIC18Fxx2 devices.
5821 The directory is initialized via configure from toplevel.
5823 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5825 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5826 the spilllocations to be compared correctly
5828 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5830 * src/SDCCast.c (decorateType): fixed bug introduced today
5832 2004-01-12 Borut Razem <borut.razem AT siol.net>
5834 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5850 * doc/sdccman.lyx: Moved and added some sections, small changes
5851 all over. Telling LaTeX to be less strict with word spacing
5852 to better keep the right margin. Changed some notes about
5853 maintainance of the ports in section 3.2.1 - is it OK like this?
5855 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5857 SDCC source changes:
5858 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5892 UPPER for immediate operands,
5893 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5895 * src/pic16/peeph.def: all peepholes with movff are commented out,
5896 because there is a problem in the pcode peep optimizer,
5897 * src/pic16/ralloc.c: the register allocator can now reuse local
5898 function symbols for another function. This saves register usage.
5899 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5901 Added file src/pic16/NOTES with information about program writing on
5902 the current port version.

5911 * src/SDCCmain.c : fixed #872250: -l command line defined library
5912 files are scanned before standard library files
5914 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5931 gen51Code): more efficient parameter receive for --model-large
5934 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5937 * src/z80/main.c: added missed needLinkerScript flags (more than
5938 one port structure defined in these file)
5939 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
5942 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

5955 needLinkerScript flag
5957 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5958 * src/pic/glue.c: added variable udata_section_name to
5959 override default uninitialized data segment definition for
5960 devices only with SHAREBANK memory (reported from Erik Epetrich)
5961 * (pic14emitOverlay): modified to emit a commented overlay segment
5962 directive when no overlay data exist
5963 * (picglue): modified to emit uninitialized data segment
5964 according to udata_section_name

5970 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5971 object file from '.rel' to '.o' in port->linker structure,
5972 changed size of fptr from 2 to 3 in port structure
5974 2004-01-07 Borut Razem <borut.razem AT siol.net>
5976 * support/scripts/sdcc.nsi: update PATH
5977 * support/scripts/sdcc.ico: craeted
5979 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
5981 * device/include/Makefile.in: fix install
5982 * doc/Makefile: fix install
5984 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5986 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5988 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5990 include information about variables allocated to the overlay
5993 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5995 * as/mcs51/lkmain.c: Help about -Y option

6007 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6009 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6010 (default behaviour).
6012 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6014 A python script to validate compiler diagnostic messages. It can be
6015 used to verify that sdcc complains about bad c source code and
6016 gives a good location of the error.
6017 * support/valdiag/Makefile,
6018 * support/valdiag/valdiag.py,
6019 * support/valdiag/tests/*
6021 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6023 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6024 * src/SDCCsymt.c (newEnumType),

6032 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6034 * src/common.h: added ifndef/define/endif macros
6035 around the header file.
6036 Bug reported from Jesus Calvino-Fraga
6038 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6040 * sdcc.spec: updated
6041 * device/include/Makefile.in: don't install CVS directories
6042 * device/lib/Makefile.in: added removal of CVS directories after install
6043 * doc/Makefile: fixed install, added local_icons
6044 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6045 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6046 * src/ds390/gen.c (genRightShift): fixed bug #870788
6047 * src/SDCCast.c (decorateType): fixed bug #870781
6049 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6051 PIC16 port related changes:
6052 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6053 added variable stackPos,
6055 * gen.c: genCall, assignResultValue: added support for
6056 pushing/retrieving function parameters to/from stack,
6057 genFunction,genEndFunction: setup stack frame for the
6059 genAddrOf: will be changed according to bug 863624
6061 * added files genutils.c and genutils.h which contain gen*
6062 debugged and optimised functions extracted from gen.c
6064 * glue.c: added variable 'externs' which holds extern symbols,
6065 pic16emitRegularMap: is modified to properly handle relocatable
6066 symbols under the new scheme,
6067 pic16createInterruptVect: is modified
6068 pic16printPublics: is modified to emit 'global' assembler directives,
6069 added pic16_printExterns to print extern symbols,
6070 pic16glue: initializes stack/frame pointer in the beginning of
6071 the assembly output. Temporary hack, will be corrected later,
6072 because gplink yet does not support stack and SDCC does not
6073 yet support a type of crt0.o object to create the final binary.
6075 * Removed many lines that contain 8051 legacy code.
6076 * The code is finally placed under a 'code' directive.
6077 * Added port specific options.
6079 * _process_pragma: simplified since now we do not need *special*
6080 include file to define SFR registers. But a separate header
6081 will be needed. This will be developed later.
6082 * _pic16_parseOptions: added, parses port specific options:
6083 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6084 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6085 --preplace-udata-with=
6087 * _pic16_setDefaultOptions: modified to initialize section names,
6088 but hack is temporarly out of order since it needs improvement.
6089 * _pic16_genAssemblerPreamble: configuration words are emitted by
6090 their address instead of their name. This part is incomplete and
6091 supports only the 18Fxx2 devices. Other devices will emit an error
6092 during assembly since they do not contain the same set of config
6094 * _pic16_genIVT: is modified,
6096 * pcode.c: added definitions for some hardware registers that are needed
6098 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6099 All PCI entries are updated. Now LFSR is supported.
6100 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6101 * added pic16_newpCodeOpLit2 to support instructions with
6102 two literal arguments
6103 * pic16_pCode2str: corrected code that emits assembler instructions
6104 with two literal operands and those that have an access bit modifier
6105 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6106 this fixes a bug which caused some labels to be lost, when an
6107 assembler directive was added, i.e. banksel,
6108 * pic16_FixRegisterBanking: improved logic that causes the insertion
6110 * InlineFunction: functions that are called once, are not any more
6111 inlined. This can be a port option in the future,
6113 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6115 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6116 hold the corresponding uninitialized symbols,
6117 * pic16_allocProcessorRegister: registers have explicit marked the
6119 * pic16_allocInternalRegister: registers are explicit marked as
6121 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6122 processing list, so bit registers were lost,
6125 * ralloc.h: added field 'accessBank' and original symbol operand
6126 in register definition,
6127 * removed the field isMapped from register definition,
6129 ** Several functions have been removed from various sources:
6130 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6131 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6132 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6133 pic16_assignRelocatableRegisters
6135 ** others have been introduced:
6136 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6137 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6139 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6141 * support/scripts/inc2h.pl: changed definition of BIT_AT
6142 to emit 'sbit at' instead of 'bit at'. This was a request.
6144 PIC16 port related preliminary changes:
6145 * gen.c: prefixed function popRegFromString with
6146 pic16_ and all references to it corrected
6147 * pcode.c: all pic16_pc_* hardware registers prefixed
6148 with underscore (_),
6149 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6150 * ralloc.c: newReg(): when register is REG_SFR then
6151 set address to rIdx,
6152 pic16_allocProcessorRegister(): marks register wasUsed=0
6153 pic16_writeUsedRegs(): added a call to assign processor
6154 registers via pic16_assignFixedRegisters
6156 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6158 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6159 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6160 variables in unused register banks. Also the SSEG is placed
6161 wherever there is enough space for it, and IDATA can be anywhere
6162 in internal RAM. For now compile using -Wl-Y[stack_size].
6163 The mem file is different for this option as well, since it
6164 makes no sense of talking about DSEG lenght.
6166 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6168 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6169 in certain cases, e.g. when ROM assignment, patch provided
6170 from Albert den Haan.
6172 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7169 before instructions that use the _STATUS register
7171 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7173 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7174 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7175 fetching of the pointer
7176 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7177 copied from genNearPointerSet()
7178 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7179 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7180 If they pop r0/r1 they must be called in the opposite order than aopOp().
7181 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7182 (resp. --stack-auto), prepared for --xstack

7191 these ports have their own __sdcc_external_start()
7193 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7195 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7196 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7197 type for bits was changed. It resulted in bit variables becoming
7198 global, which is not permitted in PIC 14 assembly output.
7200 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7202 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7204 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7206 Z80 and MCS51 linkers complaint if a public symbol is defined

7215 A few small changes that speed up the peephole optimizer.
7219 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7221 Try to make the peephole optimizer smarter by maintaining
7222 an association between the assembly source code and the
7223 iCodes that originated them. Put this information to use
7224 with a new peephole rule condition "notVolatile" so that
7225 the rules can be aggressive yet still safe.
7230 * src/mcs51/peeph.def
7232 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7236 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7237 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7238 if the left or right operand symbols have the accuse flag set.
7240 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7242 Changed the type of the result of the ! (NOT) operator to char;
7243 previously it returned the same type as the source. This allows
7244 us to eliminate all the genFloatNot functions (all of its target
7245 implementations were very buggy) since !float can use the same
7248 * src/SDCCicode.c (ast2iCode): ! returns char
7249 * src/mcs51/gen.c (genNot, genNotFloat),
7250 * src/ds390/gen.c (genNot, genNotFloat),
7251 * src/z80/gen.c (genNot, genNotFloat),
7252 * src/pic/gen.c (genNot, genNotFloat),
7253 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7257 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7258 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7259 during interrupts. Ensure WSAVE is located at a shared bank address.
7260 2. Fixed page selection in some places
7261 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7262 the registers name strings.
7263 4. Fixed "signed / unsigned compare" compiler warnings.
7264 5. The PIC port manages its own allocation of the general purpose
7265 registers, but makes no attempt to reuse them. As a result when
7266 compiling it soon runs out of general purpose registers. Some
7267 additional code was added to the files pcode.c and device.c to walk
7268 through the function call tree and rename the registers so that they
7278 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7279 genPlus() & genMinus() when the result is the same as left or right

7285 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7287 Made bitfield a distinct type from bit so that bitfields
7288 convert as per ANSI C and bits retain their traditional
7289 boolean style behaviour. Implemented bitfield support in
7297 * src/ds390/gen.c: bit v bitfield split
7298 * src/z80/gen.c: New support for bitfields
7299 * support/regression/tests/bitfields.c: reenabled z80,
7302 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7304 Rules 246.x, 247.x relate to bitfields, the others speed up
7305 access to xdata mapped I/O devices.
7307 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7309 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7311 Cleaned up genPackBits and genUnpackBits and added two helper
7312 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7313 for literal assignments in genPackBits (thanks to Frieder for
7319 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7321 Fixed bug #748310 (pointer to function type mishandled when the
7322 function name is omitted). Also fixed a SIGSEGV when a function
7323 attribute (reentrant, etc) is used on a non-function or on a
7324 function but misplaced before the parameter list.
7326 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7328 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7329 * support/Util/SDCCerr.h,
7330 * support/Util/SDCCerr.c: Added func attr misuse error msg

7351 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7353 Made the constant following the "interrupt" keyword optional. If
7354 omitted, the function will not automatically be given an entry
7355 in the interrupt vector table (similar to #pragma NOIV, but
7356 less syntacticly kludgy). The interrupt number is also now
7357 range checked. Also fixed a bug in the high order bit example
7364 * support/Util/SDCCerr.c
7365 * support/Util/SDCCerr.h
7368 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7371 * src/SDCCicode.c (operandOperation): rewritten some ops
7372 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7373 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7375 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7376 be re-activated by defining REDUCE_LITERALS)
7377 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7378 unsigned, but are signed by default
7379 * src/SDCCval.c (constVal): rearranged
7380 * src/SDCCval.c (valMod): preliminary fix
7381 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7878 it can be defined with CFLAGS when running configure
7879 * src/SDCCmain.c: fixed compiling + linking with object files
7881 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7884 added --disable-pic16-port
7885 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7886 * src/SDCCmain.c: linkOptions is changed to set *,
7887 added if/endif conditional macros to remove options help
7888 messages from optionsTable when a port is not configured, added
7889 support for the PIc16 port in the ports table, when executing
7890 the compiler with no port specified on command line, a default
7891 port is selected with the new macro DEFAULT_PORT which is
7892 defined in port.h, in setDefaultOptions() linkOptions is removed
7893 from initialization assignment, since now it is a set,
7894 parseCmdLine uses setParseWithComma for linkOptions, in
7895 linkEdit() linkOptions are accessed with new function indexSet()
7896 which returns the i'th item of a set variable. See SDCCset.c, in
7897 linkEdit() when calling buildCmdLine(), added linkOptions as
7898 last argument. Now users can pass arguments to gplink via the
7899 -Wl option, main() uses pic16glue() to glue up pic16 programs

7911 * src/pic16/glue.c: commented out some error producing lines
7912 * src/pic16/main.c: __config directives are commented out to stop
7913 gpasm complaining and test the linkage with gplink, _linkCmd and
7914 _asmCmd changed to be more gplink and gpasm friendly
7915 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7916 produced an error when parsed, peep rule 12 is added to utilize
7917 movff, but it is commented out since the pCode does not support
7918 yet a command with 2 address arguments
7920 2003-05-18 <johan AT balder>
7922 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7923 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7947 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7949 2003-05-11 Borut Razem <borut.razem AT siol.net>
7951 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7952 the path of bin directory, so that PATH is the only env. variable, which has to be set
7953 in case of standard installation.

8983 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8985 * in \sdcc\as\mcs51\ changed these files in order to create an
8986 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8987 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8988 following files to include the previous two files: aslink.dsp,
8989 Makefile.aslink, Makefile.bcc, and Makefile.in.
8991 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8992 .adb instead of .cdb
8994 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8996 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8997 value from option --iram-size.
8999 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9001 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9004 2002-09-18 <wiml AT hhhh.org>
9006 * SDCClrange.h: exposed setFromRange() and setToRange()
9007 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9008 packRegsForAccUse() (bug 542397)
9009 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9010 multiple times and emitting the fetch operations more than once
9011 added aopGetUsesAcc() function to allow binary operators to
9012 fetch their operands in the correct order; made genMinus() emit
9013 compact code for X = LITERAL - Y
9015 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9016 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9017 sprintf() in line 1267.
9019 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9020 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9023 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9024 Changes to aslink (All the changes are marked with 'JCF'):
9026 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9029 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9030 area BSEG. Also moves, if possible, the DATA area down into the internal
9031 ram so more space is available.
9033 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9036 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9037 not bytes. Function summary() which creates a memory usage summary
9038 file with extension .mem. Reports of overlaping stack and small stack
9039 size. If the space for the stack is less than 16 bytes aslink trows a
9042 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9043 the 8051. Option 'y' for memory summary output file.
9045 Changes to sdcc (All the changes are marked with 'JCF'):
9047 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9049 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9050 overlaying area for it (uses RegBankUsed[4]).
9052 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9053 bank zero as used by default. By default aslink locates the stack
9054 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9055 the creation of the .mem file. Delegates the allocation of data area
9056 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9057 the begining of the stack area to aslink.
9059 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9060 glue() in SDCCglue.c creates an area for it.
9062 2002-09-03 Borut Razem <borut.razem AT siol.net>
9063 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9064 sdcc/src/pic/glue.c:
9065 introduced atexit() handler for teporay files removal in case of
9066 errors, assertions, ...
9068 2002-08-29 Borut Razem <borut.razem AT siol.net>
9069 * sdcc/support/cpp2/auto-host_vc_in.h:
9070 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9071 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9072 Maybe there is a similar problem with BORLANDC? It should be checked!
9074 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9075 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9076 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9077 was not executed, and the compiler (cl) launched a warning:
9078 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9080 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9081 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9083 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

9086 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9087 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9088 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9089 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9090 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9091 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9092 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9093 - added Release configuration in VS projects
9094 - review of compiler an linker options
9095 - VC .exe files are generated in bin_vc directory, not to interfere
9096 with binaries generated from other projects (cygwin, mingw, bcc ...)
9098 * sdcc/src/yacc.dsp: added
9100 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9101 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9102 and insert the version number definitions from .version
9104 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9106 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9115 2002-08-11 Borut Razem <borut.razem AT siol.net>
9116 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9118 2002-08-10 Borut Razem <borut.razem AT siol.net>
9119 * src/SDCCmain.c (main):
9120 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9121 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9122 The consequence was that some temporary files were not removed.
9125 unification of code in functions tempfilename() and tempfile():
9126 function tempnam() is defined in Visual Studio 6.0 and .NET
9128 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9130 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9131 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9132 - removed compiler command line option /WX: Treats all warnings as errors
9133 - update a list of source files, included into the project
9135 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9136 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9137 changed project type to Generic Project so that can be correcly converted to VS.NET project
9139 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9141 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9145 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9146 added return 0 statements after assert() to make compiler happy
9148 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9149 added newline in the def file to keep MSC compiler satisfied
9151 * sdcc/src/z80/gen.c:
9152 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9153 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9154 - solved MSC error in function aopDump()
9156 * sdcc_vc.h: define PREFIX as "\\sdcc"
9158 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9159 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9210 Initialized the new field char *Processor field to NULL in all ports
9213 Compiler generated registers for interrupt context saving
9214 were not getting allocated.
9216 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9219 Fixed left shift. Will promote the left side of a left shift
9220 if a) left shifting more than size of operand or b) when assigned
9221 to something size > size of left side
9223 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9331 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9333 * sdcc/src/SDCCloop.c:
9334 Previous fix was not good. basic blocks that have "break" or "return" are
9335 not really partof a loop , but live ranges used in these blocks should
9336 be live thru the entire loop, so set partOfLoop but don't add them to
9339 2002-02-21 <johan AT FRIJA>
9341 * src/SDCCcse.c: fixed bug #514308
9343 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
