1885 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1887 * device/lib/printf_large.c: removed inline assembly for portability and
1888 readability. Use printf_fast if speed or size are more important.
1889 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1890 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1892 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1894 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1895 prevent compiler warning
1897 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1899 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1900 moved to level 0 and declared as static. Also they are explicit
1901 placed in access bank. This was necessery because some times they
1902 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1903 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1904 optimizations. Currently only compare to unsigned char is implemented,
1905 * src/pic16/gen.c: added fReturnIdx array,
1906 * (struct resolvedIfx) is moved to gen.h and made public,
1907 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1908 * (aopForSym): added an optimization to directly store in stack of
1909 the operand of a SEND iCode,
1910 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1911 but as registers instead (AOP_REG) using the fReturnIdx array,
1912 * (pic16_freeAsmop): remove the freed register from the
1913 _G.sregsAlloc field,
1914 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1915 a compare of 'WREG',
1916 * (pic16_popGetTempRegCond): changed function prototype, now
1917 function takes also a bitVector argument v which holds the current
1918 set of registers that are allocated for stack access by aopForSym,
1919 registers allocated in aopForSym for accessing stack symbols are not
1920 any more part of the functions usedRegs field,
1921 * (genCall): some times aopOp is called for a stack variable to be
1922 send, aopForSym might perform the push, if this is true make sure
1923 that genCall doesn't push the variable twice by testing _G.resDirect,
1924 * (genFunction): changed testing for unspecified interrupt number
1925 from 256 to INTNO_UNSPEC,
1926 * modified selection scheme of frame pointer generation. Previously
1927 if function did use local registers a frame pointer was generated,
1928 now a frame pointer is generated only if function has arguments
1929 (that need PLUSW2 register access), or has stack arguments, or the
1930 compiler is not instructed to omit the frame pointer,
1931 * (genEndFunction): before restoring local registers that were saved
1932 in the function preamble, also restore the registers that *might*
1933 have been allocated for stack access,
1934 * (genRet): removed some old comments,
1935 * (genCmp, the active (RN's) version): added a call to the
1936 pic16_genCmp_special function to perform the compare with a more
1937 robust and optimized way,
1938 * (genInline): a feature has been added in inline code generation,
1939 which allows a wildcard variable substitution when writing inline
1940 assembly. Code is incomplete and experimental therefore undocumented,
1941 * (genCast): changed order of aopOp for result and right to allow
1942 aopForSym to directly load the result if possible,
1943 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1944 perform an optimized compare on some selected special occasions,
1945 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1946 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1947 generate an IVT any more,
1948 * src/pic16/main.c (pic16_optionsTable): added command line option
1950 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1951 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1953 * src/pic16/NOTES: Raphael Neider added in list of active developers
1954 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1955 jumptable_end to prevent bug #,
1956 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1957 inCond and outCond fields,
1958 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1959 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1960 turn off register spilling,
1961 * (packRegsForOneUse): synced with other ports' versions although it
1962 is not used currently,
1963 * (pic16_packRegisters): added an optimization while reading
1964 structure bitfields, some registers may be saved (malloc code is
1965 decreased by 80 bytes)
1967 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1969 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1970 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1971 this can be optimized more?
1973 2005-03-10 Raphael Neider <rneider AT web.de>
1975 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1976 genNearPointerGet): (hopefully) fixed access to bitfields via
1977 pointers (p->bitN = x; and x = p->bitN; failed)

2590 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2592 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
2594 (setFromConditionArgs): friendly operand parser for peephole rules,
2595 (operandBaseName, operandsNotRelated): new peephole condition
2596 "operandsNotRelated" -- similar to "operandsNotSame", but takes
2597 architecture specific register naming into account, handles n-way
2598 comparisons, and supports quoted literals
2599 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
2601 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2609 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2611 Adding support for replacing ljmps with sjmps in jumptables
2612 generated for switch statements. For now you need to set the
2613 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2614 Now 4 algorithms for mcs51 jumptable generation are used:
2615 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2616 addresses loaded pc-relative for up to 112 cases and stack-pushing
2617 target addresses loaded with offset from dptr for up to 256 cases.
2619 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2620 * src/mcs51/main.c: adapted constants for switch table generation
2621 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2643 Large cummulative patch for pic16 port.
2644 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2645 to call when a stack overflow occurs,
2646 * (malloc.h): added CVS Id tag,
2647 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2649 * added libc directory. The current version of LibC contains string
2650 functions, ctype functions and macros and some functions of the
2651 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2652 be extensively tested in the future. Standard disclaimer here.
2653 Library is not automatically build yet. But one can build it by
2654 invoking 'make' inside the libc directory.
2655 * added ADC library under libio. Preliminary version yet.
2657 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2661 temporary registers, its a buggy feature and will be removed,
2662 * (pic16_popGet): set register instance field in AOP_CRY,
2663 * (pic16_outBitC): fixed for results in size greater than 1,
2664 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2665 * (pic16_storeForReturn): optimized return of 0,
2666 * (genCmp): experimental code for new genCmp which uses PIC18's
2667 special compare&skip instructions. Initial tests fail some times
2668 with variables grater than 1 byte in size, so new code is disabled,
2669 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2671 * (genCast): began a fix to optimize the casting of a bit to another
2672 bit, now assigning a bitfield to another bitfield will fail, sorry,
2673 * src/pic16/main.c: disabled the use of lr-support feature,
2674 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2675 * added some function prototypes, added function _debugf prototype,
2676 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2677 bits with offset (case PO_GPR_BIT),
2678 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2680 * (isBankInstruction): modified to return 0 for no banking instruction,
2681 and 1 for banking instruction,
2682 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2683 caused stop processing pCodes after a inline assembly block,
2684 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2685 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2686 registers when it shouldn't,
2687 * src/pic16/ralloc.c (allocReg): add preliminary support for
2688 supporting a limited set of temporary registers,
2690 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2692 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2693 genDataPointerSet): ensure assignments always copy in MSB to LSB
2695 (loadRegFromAop): recognize CLRH optimization,
2696 (genFunction): optimize RECEIVE iCodes in reentrant functions
2698 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2700 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2701 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2703 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2709 * device/lib/_gptrget.c (_gptrget),
2710 * device/lib/_gptrgetc.c (_gptrgetc),
2711 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2712 instead of sjmp to ret
2713 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2714 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2716 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5692 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
5695 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5697 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5698 loaded with the linker search paths (-L arguments) and the libraries
5699 to be linked with the current source (-l arguments). Changes
5700 currently will affect only the pic16 port.
5701 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5702 include path the port specific paths and port specific libraries,
5703 * gplink command now contains the $3 argument,
5704 * src/pic16/device.h,
5705 * src/pic16/device.c,: structure PIC_device is made public and
5706 renamed to PIC16_device, the same for variable Pics which is renamed
5707 to Pics16. Updated all references to them.
5708 * src/pic16/glue.c (pic16glue): corrected bug with code
5709 initialization which bypassed the variable initializations block.
5711 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5712 COMPILE_FLAGS and added the --nostdinc option
5714 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5716 * device/include/mc68hc908jb8.h: Register defs for another member
5717 of the hc08 family. Contributed by Bjorn Bringert - thanks!
5719 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5721 Documenting changes from previous commits.
5722 * configure.in (version 1.56),
5723 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5724 when generating output files to configure the pic16 library,
5725 but now I've commented it out, since gputils aren't installed in the
5726 SF compile farm, so library won't compile
5728 * device/lib/Makefile.in (version 1.56): initially I've added in
5729 target 'all' the prerequestive 'model-pic16' so it compiled the
5730 pic16 library, but now I've commented it out for the same reasons
5732 * added targets 'model-pic16' and 'objects-pic16' to compile the
5734 * added target 'port-specific-objects-pic16' to handle the
5735 generated libraries and copy them into the build/ directory
5736 * added target 'clean-intermediate-pic16' to clean intermediate
5737 files into pic16 directory
5738 * in target 'installdirs' added line to create directory pic16 in
5739 the installation path
5741 * device/include/Makefile.in (version 1.11): in target 'install'
5742 added lines to copy all header files to installation path,
5743 * in target 'installdirs' added line create directory for pic16
5744 headers in the installation path

5759 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5760 option so that it actually works. Made it specific to the z80, since
5761 the gbz80 doesn't have these kinds of I/O ports.
5763 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5765 * device/include/z180.h,

5778 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5780 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5781 changed interrupt vector table generation to only emit declared vectors.
5782 * device/include/Makefile.in: added missing backslash
5783 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5787 Mainly changes to support compilation of the device libraries
5788 * src/pic16/device.c: stack is allocated via symbol and not
5789 via literal number. The symbol is placed in the corresponding
5790 position of the data ram
5791 * (pic16_dump_section): relocatable and absolute uninitialized
5792 data are now emitted in sorted order to reduce section naming,
5793 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5794 weren't marked as being in the access bank,
5796 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5798 Added portion of GNU PIC Library under the directory
5799 device/include/pic16 and device/lib/pic16. These files
5800 contain the declarations of SFRs for the PIC18Fxx2 devices.
5801 The directory is initialized via configure from toplevel.
5803 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5805 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5806 the spilllocations to be compared correctly
5808 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5810 * src/SDCCast.c (decorateType): fixed bug introduced today
5812 2004-01-12 Borut Razem <borut.razem AT siol.net>
5814 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5819 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5820 in simpler and even better code
5822 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5824 * src/SDCCicode.c (operandOperation): fixed bug #874819

5828 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5830 * doc/sdccman.lyx: Moved and added some sections, small changes
5831 all over. Telling LaTeX to be less strict with word spacing
5832 to better keep the right margin. Changed some notes about
5833 maintainance of the ports in section 3.2.1 - is it OK like this?
5835 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5837 SDCC source changes:
5838 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5871 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5872 UPPER for immediate operands,
5873 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5875 * src/pic16/peeph.def: all peepholes with movff are commented out,
5876 because there is a problem in the pcode peep optimizer,
5877 * src/pic16/ralloc.c: the register allocator can now reuse local
5878 function symbols for another function. This saves register usage.
5879 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5881 Added file src/pic16/NOTES with information about program writing on
5882 the current port version.

5891 * src/SDCCmain.c : fixed #872250: -l command line defined library
5892 files are scanned before standard library files
5894 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5911 gen51Code): more efficient parameter receive for --model-large
5914 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5917 * src/z80/main.c: added missed needLinkerScript flags (more than
5918 one port structure defined in these file)
5919 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5935 needLinkerScript flag
5937 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5938 * src/pic/glue.c: added variable udata_section_name to
5939 override default uninitialized data segment definition for
5940 devices only with SHAREBANK memory (reported from Erik Epetrich)
5941 * (pic14emitOverlay): modified to emit a commented overlay segment
5942 directive when no overlay data exist
5943 * (picglue): modified to emit uninitialized data segment
5944 according to udata_section_name

5949 arguments via -W option
5950 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5951 object file from '.rel' to '.o' in port->linker structure,
5952 changed size of fptr from 2 to 3 in port structure
5954 2004-01-07 Borut Razem <borut.razem AT siol.net>
5956 * support/scripts/sdcc.nsi: update PATH
5957 * support/scripts/sdcc.ico: craeted
5959 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5962 * doc/Makefile: fix install
5964 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5966 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5968 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5970 include information about variables allocated to the overlay
5973 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5975 * as/mcs51/lkmain.c: Help about -Y option

5987 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5989 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5990 (default behaviour).
5992 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5994 A python script to validate compiler diagnostic messages. It can be
5995 used to verify that sdcc complains about bad c source code and
5996 gives a good location of the error.
5997 * support/valdiag/Makefile,
5998 * support/valdiag/valdiag.py,
5999 * support/valdiag/tests/*
6001 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6003 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6012 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6014 * src/common.h: added ifndef/define/endif macros
6015 around the header file.
6016 Bug reported from Jesus Calvino-Fraga
6018 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6020 * sdcc.spec: updated
6021 * device/include/Makefile.in: don't install CVS directories
6022 * device/lib/Makefile.in: added removal of CVS directories after install
6023 * doc/Makefile: fixed install, added local_icons
6024 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6025 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6026 * src/ds390/gen.c (genRightShift): fixed bug #870788
6027 * src/SDCCast.c (decorateType): fixed bug #870781
6029 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6031 PIC16 port related changes:
6032 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6033 added variable stackPos,
6035 * gen.c: genCall, assignResultValue: added support for
6036 pushing/retrieving function parameters to/from stack,
6037 genFunction,genEndFunction: setup stack frame for the
6039 genAddrOf: will be changed according to bug 863624
6041 * added files genutils.c and genutils.h which contain gen*
6042 debugged and optimised functions extracted from gen.c
6044 * glue.c: added variable 'externs' which holds extern symbols,
6045 pic16emitRegularMap: is modified to properly handle relocatable
6046 symbols under the new scheme,
6047 pic16createInterruptVect: is modified
6048 pic16printPublics: is modified to emit 'global' assembler directives,
6049 added pic16_printExterns to print extern symbols,
6050 pic16glue: initializes stack/frame pointer in the beginning of
6051 the assembly output. Temporary hack, will be corrected later,
6052 because gplink yet does not support stack and SDCC does not
6053 yet support a type of crt0.o object to create the final binary.
6055 * Removed many lines that contain 8051 legacy code.
6056 * The code is finally placed under a 'code' directive.
6057 * Added port specific options.
6059 * _process_pragma: simplified since now we do not need *special*
6060 include file to define SFR registers. But a separate header
6061 will be needed. This will be developed later.
6062 * _pic16_parseOptions: added, parses port specific options:
6063 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6064 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6065 --preplace-udata-with=
6067 * _pic16_setDefaultOptions: modified to initialize section names,
6068 but hack is temporarly out of order since it needs improvement.
6069 * _pic16_genAssemblerPreamble: configuration words are emitted by
6070 their address instead of their name. This part is incomplete and
6071 supports only the 18Fxx2 devices. Other devices will emit an error
6072 during assembly since they do not contain the same set of config
6074 * _pic16_genIVT: is modified,
6076 * pcode.c: added definitions for some hardware registers that are needed
6078 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6079 All PCI entries are updated. Now LFSR is supported.
6080 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6081 * added pic16_newpCodeOpLit2 to support instructions with
6082 two literal arguments
6083 * pic16_pCode2str: corrected code that emits assembler instructions
6084 with two literal operands and those that have an access bit modifier
6085 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6086 this fixes a bug which caused some labels to be lost, when an
6087 assembler directive was added, i.e. banksel,
6088 * pic16_FixRegisterBanking: improved logic that causes the insertion
6090 * InlineFunction: functions that are called once, are not any more
6091 inlined. This can be a port option in the future,
6093 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6095 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6096 hold the corresponding uninitialized symbols,
6097 * pic16_allocProcessorRegister: registers have explicit marked the
6099 * pic16_allocInternalRegister: registers are explicit marked as
6101 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6102 processing list, so bit registers were lost,
6105 * ralloc.h: added field 'accessBank' and original symbol operand
6106 in register definition,
6107 * removed the field isMapped from register definition,
6109 ** Several functions have been removed from various sources:
6110 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6111 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6112 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6113 pic16_assignRelocatableRegisters
6115 ** others have been introduced:
6116 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6117 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6119 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6121 * support/scripts/inc2h.pl: changed definition of BIT_AT
6122 to emit 'sbit at' instead of 'bit at'. This was a request.
6124 PIC16 port related preliminary changes:
6125 * gen.c: prefixed function popRegFromString with
6126 pic16_ and all references to it corrected
6127 * pcode.c: all pic16_pc_* hardware registers prefixed
6128 with underscore (_),
6129 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6130 * ralloc.c: newReg(): when register is REG_SFR then
6131 set address to rIdx,
6132 pic16_allocProcessorRegister(): marks register wasUsed=0
6133 pic16_writeUsedRegs(): added a call to assign processor
6134 registers via pic16_assignFixedRegisters
6136 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6138 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6139 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6140 variables in unused register banks. Also the SSEG is placed
6141 wherever there is enough space for it, and IDATA can be anywhere
6142 in internal RAM. For now compile using -Wl-Y[stack_size].
6143 The mem file is different for this option as well, since it
6144 makes no sense of talking about DSEG lenght.
6146 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6148 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6149 in certain cases, e.g. when ROM assignment, patch provided
6150 from Albert den Haan.
6152 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7170 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
7171 these ports have their own __sdcc_external_start()
7173 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7175 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7176 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7177 type for bits was changed. It resulted in bit variables becoming
7178 global, which is not permitted in PIC 14 assembly output.
7180 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7182 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7184 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7186 Z80 and MCS51 linkers complaint if a public symbol is defined
7187 in more than one library module:

7195 A few small changes that speed up the peephole optimizer.
7199 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7201 Try to make the peephole optimizer smarter by maintaining
7202 an association between the assembly source code and the
7203 iCodes that originated them. Put this information to use
7204 with a new peephole rule condition "notVolatile" so that
7205 the rules can be aggressive yet still safe.
7210 * src/mcs51/peeph.def
7212 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7216 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7217 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7218 if the left or right operand symbols have the accuse flag set.
7220 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7222 Changed the type of the result of the ! (NOT) operator to char;
7223 previously it returned the same type as the source. This allows
7224 us to eliminate all the genFloatNot functions (all of its target
7225 implementations were very buggy) since !float can use the same
7228 * src/SDCCicode.c (ast2iCode): ! returns char
7229 * src/mcs51/gen.c (genNot, genNotFloat),
7230 * src/ds390/gen.c (genNot, genNotFloat),
7231 * src/z80/gen.c (genNot, genNotFloat),
7232 * src/pic/gen.c (genNot, genNotFloat),
7233 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7235 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7237 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7238 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7239 during interrupts. Ensure WSAVE is located at a shared bank address.
7240 2. Fixed page selection in some places
7241 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7242 the registers name strings.
7243 4. Fixed "signed / unsigned compare" compiler warnings.
7244 5. The PIC port manages its own allocation of the general purpose
7245 registers, but makes no attempt to reuse them. As a result when
7246 compiling it soon runs out of general purpose registers. Some
7247 additional code was added to the files pcode.c and device.c to walk
7248 through the function call tree and rename the registers so that they
7258 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7259 genPlus() & genMinus() when the result is the same as left or right

7265 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7267 Made bitfield a distinct type from bit so that bitfields
7268 convert as per ANSI C and bits retain their traditional
7269 boolean style behaviour. Implemented bitfield support in
7277 * src/ds390/gen.c: bit v bitfield split
7278 * src/z80/gen.c: New support for bitfields
7279 * support/regression/tests/bitfields.c: reenabled z80,
7282 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7284 Rules 246.x, 247.x relate to bitfields, the others speed up
7285 access to xdata mapped I/O devices.
7287 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7289 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7291 Cleaned up genPackBits and genUnpackBits and added two helper
7292 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7293 for literal assignments in genPackBits (thanks to Frieder for
7299 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7301 Fixed bug #748310 (pointer to function type mishandled when the
7302 function name is omitted). Also fixed a SIGSEGV when a function
7303 attribute (reentrant, etc) is used on a non-function or on a
7304 function but misplaced before the parameter list.
7306 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7308 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7309 * support/Util/SDCCerr.h,
7310 * support/Util/SDCCerr.c: Added func attr misuse error msg

7331 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7333 Made the constant following the "interrupt" keyword optional. If
7334 omitted, the function will not automatically be given an entry
7335 in the interrupt vector table (similar to #pragma NOIV, but
7336 less syntacticly kludgy). The interrupt number is also now
7337 range checked. Also fixed a bug in the high order bit example
7344 * support/Util/SDCCerr.c
7345 * support/Util/SDCCerr.h

7351 * src/SDCCicode.c (operandOperation): rewritten some ops
7352 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7353 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7355 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7356 be re-activated by defining REDUCE_LITERALS)
7357 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7358 unsigned, but are signed by default
7359 * src/SDCCval.c (constVal): rearranged
7360 * src/SDCCval.c (valMod): preliminary fix
7361 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7404 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7405 * src/SDCCval.c (valDiv, valMod): fixed signdness
7406 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7407 signedness of modulo, left and right shift

7784 for a non-native english speaker.
7785 Please feel free to add to the manual or to correct my changes.

7813 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7814 the regression tests I'm not brave enough to enable 245.b, 245.c
7815 * doc/sdccman.lyx: added latex preamble for hyperref package.
7816 Using pdflatex this will give you a hyperlinked pdf file with
7817 bookmarks. (prepend '%' before /usepackage if this breaks something)

7855 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7857 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7858 it can be defined with CFLAGS when running configure
7859 * src/SDCCmain.c: fixed compiling + linking with object files
7861 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7863 * configure.in: configure for pic16 port,
7864 added --disable-pic16-port
7865 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7866 * src/SDCCmain.c: linkOptions is changed to set *,
7867 added if/endif conditional macros to remove options help
7868 messages from optionsTable when a port is not configured, added
7869 support for the PIc16 port in the ports table, when executing
7870 the compiler with no port specified on command line, a default
7871 port is selected with the new macro DEFAULT_PORT which is
7872 defined in port.h, in setDefaultOptions() linkOptions is removed
7873 from initialization assignment, since now it is a set,
7874 parseCmdLine uses setParseWithComma for linkOptions, in
7875 linkEdit() linkOptions are accessed with new function indexSet()
7876 which returns the i'th item of a set variable. See SDCCset.c, in
7877 linkEdit() when calling buildCmdLine(), added linkOptions as
7878 last argument. Now users can pass arguments to gplink via the
7879 -Wl option, main() uses pic16glue() to glue up pic16 programs
7880 * src/SDCCpeeph.c: various changes to support pic16

7891 * src/pic16/glue.c: commented out some error producing lines
7892 * src/pic16/main.c: __config directives are commented out to stop
7893 gpasm complaining and test the linkage with gplink, _linkCmd and
7894 _asmCmd changed to be more gplink and gpasm friendly
7895 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7896 produced an error when parsed, peep rule 12 is added to utilize
7897 movff, but it is commented out since the pCode does not support
7898 yet a command with 2 address arguments
7900 2003-05-18 <johan AT balder>
7902 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7903 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7927 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7929 2003-05-11 Borut Razem <borut.razem AT siol.net>
7931 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7932 the path of bin directory, so that PATH is the only env. variable, which has to be set
7933 in case of standard installation.
7934 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8963 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8965 * in \sdcc\as\mcs51\ changed these files in order to create an
8966 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8967 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8968 following files to include the previous two files: aslink.dsp,
8969 Makefile.aslink, Makefile.bcc, and Makefile.in.
8971 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8972 .adb instead of .cdb
8974 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8976 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8977 value from option --iram-size.
8979 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8981 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8984 2002-09-18 <wiml AT hhhh.org>
8986 * SDCClrange.h: exposed setFromRange() and setToRange()
8987 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8988 packRegsForAccUse() (bug 542397)
8989 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8990 multiple times and emitting the fetch operations more than once
8991 added aopGetUsesAcc() function to allow binary operators to
8992 fetch their operands in the correct order; made genMinus() emit
8993 compact code for X = LITERAL - Y
8995 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8996 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8997 sprintf() in line 1267.
8999 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9000 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9003 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9004 Changes to aslink (All the changes are marked with 'JCF'):
9006 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9009 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9010 area BSEG. Also moves, if possible, the DATA area down into the internal
9011 ram so more space is available.
9013 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9016 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9017 not bytes. Function summary() which creates a memory usage summary
9018 file with extension .mem. Reports of overlaping stack and small stack
9019 size. If the space for the stack is less than 16 bytes aslink trows a
9022 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9023 the 8051. Option 'y' for memory summary output file.
9025 Changes to sdcc (All the changes are marked with 'JCF'):
9027 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9029 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9030 overlaying area for it (uses RegBankUsed[4]).
9032 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9033 bank zero as used by default. By default aslink locates the stack
9034 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9035 the creation of the .mem file. Delegates the allocation of data area
9036 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9037 the begining of the stack area to aslink.
9039 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9040 glue() in SDCCglue.c creates an area for it.
9042 2002-09-03 Borut Razem <borut.razem AT siol.net>
9043 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9044 sdcc/src/pic/glue.c:
9045 introduced atexit() handler for teporay files removal in case of
9046 errors, assertions, ...
9048 2002-08-29 Borut Razem <borut.razem AT siol.net>
9049 * sdcc/support/cpp2/auto-host_vc_in.h:
9050 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9051 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9052 Maybe there is a similar problem with BORLANDC? It should be checked!
9054 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9055 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9056 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9057 was not executed, and the compiler (cl) launched a warning:
9058 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9060 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9061 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

9073 - added Release configuration in VS projects
9074 - review of compiler an linker options
9075 - VC .exe files are generated in bin_vc directory, not to interfere
9076 with binaries generated from other projects (cygwin, mingw, bcc ...)
9078 * sdcc/src/yacc.dsp: added
9080 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9081 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9082 and insert the version number definitions from .version
9084 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9086 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9093 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9095 2002-08-11 Borut Razem <borut.razem AT siol.net>
9096 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9098 2002-08-10 Borut Razem <borut.razem AT siol.net>
9099 * src/SDCCmain.c (main):
9100 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9101 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9102 The consequence was that some temporary files were not removed.
9105 unification of code in functions tempfilename() and tempfile():
9106 function tempnam() is defined in Visual Studio 6.0 and .NET
9108 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9110 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9111 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9112 - removed compiler command line option /WX: Treats all warnings as errors
9113 - update a list of source files, included into the project
9115 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9116 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9117 changed project type to Generic Project so that can be correcly converted to VS.NET project
9119 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9121 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9125 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9126 added return 0 statements after assert() to make compiler happy
9128 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9129 added newline in the def file to keep MSC compiler satisfied
9131 * sdcc/src/z80/gen.c:
9132 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9133 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9134 - solved MSC error in function aopDump()
9136 * sdcc_vc.h: define PREFIX as "\\sdcc"
9138 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9139 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9194 were not getting allocated.
9196 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9199 Fixed left shift. Will promote the left side of a left shift
9200 if a) left shifting more than size of operand or b) when assigned
9201 to something size > size of left side
9203 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9313 * sdcc/src/SDCCloop.c:
9314 Previous fix was not good. basic blocks that have "break" or "return" are
9315 not really partof a loop , but live ranges used in these blocks should
9316 be live thru the entire loop, so set partOfLoop but don't add them to
9319 2002-02-21 <johan AT FRIJA>

10159 2001-09-03 Michael Hope <michaelh AT juju.net.nz>
10161 * link/z80/aslink.h: Fixed path for PATH_MAX
10163 2001-09-02 Michael Hope <michaelh AT juju.net.nz>

10178 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
10180 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
10182 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
10184 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

10188 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
10190 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
10192 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
10194 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
10196 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
10198 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
10200 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
