1836 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1837 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1838 always available in leading double underscore form. The C99 support is
1839 mostly missing, but it's a start.
1840 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1919 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1921 * device/lib/printf_large.c: removed inline assembly for portability and
1922 readability. Use printf_fast if speed or size are more important.
1923 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1924 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1926 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1928 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1929 prevent compiler warning
1931 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1933 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1934 moved to level 0 and declared as static. Also they are explicit
1935 placed in access bank. This was necessery because some times they
1936 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1937 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1938 optimizations. Currently only compare to unsigned char is implemented,
1939 * src/pic16/gen.c: added fReturnIdx array,
1940 * (struct resolvedIfx) is moved to gen.h and made public,
1941 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1942 * (aopForSym): added an optimization to directly store in stack of
1943 the operand of a SEND iCode,
1944 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1945 but as registers instead (AOP_REG) using the fReturnIdx array,
1946 * (pic16_freeAsmop): remove the freed register from the
1947 _G.sregsAlloc field,
1948 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1949 a compare of 'WREG',
1950 * (pic16_popGetTempRegCond): changed function prototype, now
1951 function takes also a bitVector argument v which holds the current
1952 set of registers that are allocated for stack access by aopForSym,
1953 registers allocated in aopForSym for accessing stack symbols are not
1954 any more part of the functions usedRegs field,
1955 * (genCall): some times aopOp is called for a stack variable to be
1956 send, aopForSym might perform the push, if this is true make sure
1957 that genCall doesn't push the variable twice by testing _G.resDirect,
1958 * (genFunction): changed testing for unspecified interrupt number
1959 from 256 to INTNO_UNSPEC,
1960 * modified selection scheme of frame pointer generation. Previously
1961 if function did use local registers a frame pointer was generated,
1962 now a frame pointer is generated only if function has arguments
1963 (that need PLUSW2 register access), or has stack arguments, or the
1964 compiler is not instructed to omit the frame pointer,
1965 * (genEndFunction): before restoring local registers that were saved
1966 in the function preamble, also restore the registers that *might*
1967 have been allocated for stack access,
1968 * (genRet): removed some old comments,
1969 * (genCmp, the active (RN's) version): added a call to the
1970 pic16_genCmp_special function to perform the compare with a more
1971 robust and optimized way,
1972 * (genInline): a feature has been added in inline code generation,
1973 which allows a wildcard variable substitution when writing inline
1974 assembly. Code is incomplete and experimental therefore undocumented,
1975 * (genCast): changed order of aopOp for result and right to allow
1976 aopForSym to directly load the result if possible,
1977 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1978 perform an optimized compare on some selected special occasions,
1979 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1980 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1981 generate an IVT any more,
1982 * src/pic16/main.c (pic16_optionsTable): added command line option
1984 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1985 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1987 * src/pic16/NOTES: Raphael Neider added in list of active developers
1988 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1989 jumptable_end to prevent bug #,
1990 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1991 inCond and outCond fields,
1992 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1993 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1994 turn off register spilling,
1995 * (packRegsForOneUse): synced with other ports' versions although it
1996 is not used currently,
1997 * (pic16_packRegisters): added an optimization while reading
1998 structure bitfields, some registers may be saved (malloc code is
1999 decreased by 80 bytes)
2001 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2003 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2004 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2005 this can be optimized more?
2007 2005-03-10 Raphael Neider <rneider AT web.de>
2009 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2010 genNearPointerGet): (hopefully) fixed access to bitfields via
2011 pointers (p->bitN = x; and x = p->bitN; failed)

2645 Adding support for replacing ljmps with sjmps in jumptables
2646 generated for switch statements. For now you need to set the
2647 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2648 Now 4 algorithms for mcs51 jumptable generation are used:
2649 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2650 addresses loaded pc-relative for up to 112 cases and stack-pushing
2651 target addresses loaded with offset from dptr for up to 256 cases.

2678 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2679 to call when a stack overflow occurs,
2680 * (malloc.h): added CVS Id tag,
2681 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2683 * added libc directory. The current version of LibC contains string
2684 functions, ctype functions and macros and some functions of the
2685 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2686 be extensively tested in the future. Standard disclaimer here.
2687 Library is not automatically build yet. But one can build it by
2688 invoking 'make' inside the libc directory.
2689 * added ADC library under libio. Preliminary version yet.
2691 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2698 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2699 * (pic16_storeForReturn): optimized return of 0,
2700 * (genCmp): experimental code for new genCmp which uses PIC18's
2701 special compare&skip instructions. Initial tests fail some times
2702 with variables grater than 1 byte in size, so new code is disabled,
2703 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2705 * (genCast): began a fix to optimize the casting of a bit to another
2706 bit, now assigning a bitfield to another bitfield will fail, sorry,
2707 * src/pic16/main.c: disabled the use of lr-support feature,
2708 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2711 bits with offset (case PO_GPR_BIT),
2712 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2714 * (isBankInstruction): modified to return 0 for no banking instruction,
2715 and 1 for banking instruction,
2716 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2717 caused stop processing pCodes after a inline assembly block,
2718 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2719 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2720 registers when it shouldn't,
2721 * src/pic16/ralloc.c (allocReg): add preliminary support for
2722 supporting a limited set of temporary registers,
2724 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2726 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2727 genDataPointerSet): ensure assignments always copy in MSB to LSB
2729 (loadRegFromAop): recognize CLRH optimization,
2730 (genFunction): optimize RECEIVE iCodes in reentrant functions
2732 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2734 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5729 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5731 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5732 loaded with the linker search paths (-L arguments) and the libraries
5733 to be linked with the current source (-l arguments). Changes
5734 currently will affect only the pic16 port.
5735 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5736 include path the port specific paths and port specific libraries,
5737 * gplink command now contains the $3 argument,
5738 * src/pic16/device.h,
5739 * src/pic16/device.c,: structure PIC_device is made public and
5740 renamed to PIC16_device, the same for variable Pics which is renamed
5741 to Pics16. Updated all references to them.
5742 * src/pic16/glue.c (pic16glue): corrected bug with code

5753 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5755 Documenting changes from previous commits.
5756 * configure.in (version 1.56),
5757 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5758 when generating output files to configure the pic16 library,
5759 but now I've commented it out, since gputils aren't installed in the
5760 SF compile farm, so library won't compile
5762 * device/lib/Makefile.in (version 1.56): initially I've added in
5763 target 'all' the prerequestive 'model-pic16' so it compiled the
5764 pic16 library, but now I've commented it out for the same reasons
5766 * added targets 'model-pic16' and 'objects-pic16' to compile the
5768 * added target 'port-specific-objects-pic16' to handle the
5769 generated libraries and copy them into the build/ directory
5770 * added target 'clean-intermediate-pic16' to clean intermediate
5771 files into pic16 directory
5772 * in target 'installdirs' added line to create directory pic16 in
5773 the installation path
5775 * device/include/Makefile.in (version 1.11): in target 'install'
5776 added lines to copy all header files to installation path,
5777 * in target 'installdirs' added line create directory for pic16
5778 headers in the installation path

5793 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5794 option so that it actually works. Made it specific to the z80, since
5795 the gbz80 doesn't have these kinds of I/O ports.
5797 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5799 * device/include/z180.h,

5812 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5814 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5815 changed interrupt vector table generation to only emit declared vectors.
5816 * device/include/Makefile.in: added missing backslash
5817 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5819 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5821 Mainly changes to support compilation of the device libraries
5822 * src/pic16/device.c: stack is allocated via symbol and not
5823 via literal number. The symbol is placed in the corresponding
5824 position of the data ram
5825 * (pic16_dump_section): relocatable and absolute uninitialized
5826 data are now emitted in sorted order to reduce section naming,
5827 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5828 weren't marked as being in the access bank,
5830 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5832 Added portion of GNU PIC Library under the directory
5833 device/include/pic16 and device/lib/pic16. These files
5834 contain the declarations of SFRs for the PIC18Fxx2 devices.
5835 The directory is initialized via configure from toplevel.
5837 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5839 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5840 the spilllocations to be compared correctly
5842 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5844 * src/SDCCast.c (decorateType): fixed bug introduced today
5846 2004-01-12 Borut Razem <borut.razem AT siol.net>
5848 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

5851 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5853 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5854 in simpler and even better code
5856 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5858 * src/SDCCicode.c (operandOperation): fixed bug #874819

5864 * doc/sdccman.lyx: Moved and added some sections, small changes
5865 all over. Telling LaTeX to be less strict with word spacing
5866 to better keep the right margin. Changed some notes about
5867 maintainance of the ports in section 3.2.1 - is it OK like this?
5869 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5906 UPPER for immediate operands,
5907 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5909 * src/pic16/peeph.def: all peepholes with movff are commented out,
5910 because there is a problem in the pcode peep optimizer,
5911 * src/pic16/ralloc.c: the register allocator can now reuse local
5912 function symbols for another function. This saves register usage.
5913 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5915 Added file src/pic16/NOTES with information about program writing on
5916 the current port version.

5945 gen51Code): more efficient parameter receive for --model-large
5948 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5951 * src/z80/main.c: added missed needLinkerScript flags (more than
5952 one port structure defined in these file)
5953 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5969 needLinkerScript flag
5971 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5972 * src/pic/glue.c: added variable udata_section_name to
5973 override default uninitialized data segment definition for
5974 devices only with SHAREBANK memory (reported from Erik Epetrich)
5975 * (pic14emitOverlay): modified to emit a commented overlay segment
5976 directive when no overlay data exist
5977 * (picglue): modified to emit uninitialized data segment
5978 according to udata_section_name

5984 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5985 object file from '.rel' to '.o' in port->linker structure,
5986 changed size of fptr from 2 to 3 in port structure
5988 2004-01-07 Borut Razem <borut.razem AT siol.net>
5990 * support/scripts/sdcc.nsi: update PATH
5991 * support/scripts/sdcc.ico: craeted

6004 include information about variables allocated to the overlay
6007 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6009 * as/mcs51/lkmain.c: Help about -Y option

6021 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6023 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6024 (default behaviour).
6026 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6028 A python script to validate compiler diagnostic messages. It can be
6029 used to verify that sdcc complains about bad c source code and
6030 gives a good location of the error.
6031 * support/valdiag/Makefile,
6032 * support/valdiag/valdiag.py,
6033 * support/valdiag/tests/*
6035 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6037 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6048 * src/common.h: added ifndef/define/endif macros
6049 around the header file.
6050 Bug reported from Jesus Calvino-Fraga
6052 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6054 * sdcc.spec: updated
6055 * device/include/Makefile.in: don't install CVS directories
6056 * device/lib/Makefile.in: added removal of CVS directories after install
6057 * doc/Makefile: fixed install, added local_icons
6058 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6059 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6060 * src/ds390/gen.c (genRightShift): fixed bug #870788
6061 * src/SDCCast.c (decorateType): fixed bug #870781
6063 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6065 PIC16 port related changes:
6066 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6067 added variable stackPos,
6069 * gen.c: genCall, assignResultValue: added support for
6070 pushing/retrieving function parameters to/from stack,
6071 genFunction,genEndFunction: setup stack frame for the
6073 genAddrOf: will be changed according to bug 863624
6075 * added files genutils.c and genutils.h which contain gen*
6076 debugged and optimised functions extracted from gen.c
6078 * glue.c: added variable 'externs' which holds extern symbols,
6079 pic16emitRegularMap: is modified to properly handle relocatable
6080 symbols under the new scheme,
6081 pic16createInterruptVect: is modified
6082 pic16printPublics: is modified to emit 'global' assembler directives,
6083 added pic16_printExterns to print extern symbols,
6084 pic16glue: initializes stack/frame pointer in the beginning of
6085 the assembly output. Temporary hack, will be corrected later,
6086 because gplink yet does not support stack and SDCC does not
6087 yet support a type of crt0.o object to create the final binary.
6089 * Removed many lines that contain 8051 legacy code.
6090 * The code is finally placed under a 'code' directive.
6091 * Added port specific options.
6093 * _process_pragma: simplified since now we do not need *special*
6094 include file to define SFR registers. But a separate header
6095 will be needed. This will be developed later.
6096 * _pic16_parseOptions: added, parses port specific options:
6097 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6098 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6099 --preplace-udata-with=
6101 * _pic16_setDefaultOptions: modified to initialize section names,
6102 but hack is temporarly out of order since it needs improvement.
6103 * _pic16_genAssemblerPreamble: configuration words are emitted by
6104 their address instead of their name. This part is incomplete and
6105 supports only the 18Fxx2 devices. Other devices will emit an error
6106 during assembly since they do not contain the same set of config
6108 * _pic16_genIVT: is modified,
6110 * pcode.c: added definitions for some hardware registers that are needed
6112 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6113 All PCI entries are updated. Now LFSR is supported.
6114 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6115 * added pic16_newpCodeOpLit2 to support instructions with
6116 two literal arguments
6117 * pic16_pCode2str: corrected code that emits assembler instructions
6118 with two literal operands and those that have an access bit modifier
6119 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6120 this fixes a bug which caused some labels to be lost, when an
6121 assembler directive was added, i.e. banksel,
6122 * pic16_FixRegisterBanking: improved logic that causes the insertion
6124 * InlineFunction: functions that are called once, are not any more
6125 inlined. This can be a port option in the future,
6127 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6129 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6130 hold the corresponding uninitialized symbols,
6131 * pic16_allocProcessorRegister: registers have explicit marked the
6133 * pic16_allocInternalRegister: registers are explicit marked as
6135 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6136 processing list, so bit registers were lost,
6139 * ralloc.h: added field 'accessBank' and original symbol operand
6140 in register definition,
6141 * removed the field isMapped from register definition,
6143 ** Several functions have been removed from various sources:
6144 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6145 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6146 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6147 pic16_assignRelocatableRegisters
6149 ** others have been introduced:
6150 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6151 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6153 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6155 * support/scripts/inc2h.pl: changed definition of BIT_AT
6156 to emit 'sbit at' instead of 'bit at'. This was a request.
6158 PIC16 port related preliminary changes:
6159 * gen.c: prefixed function popRegFromString with
6160 pic16_ and all references to it corrected
6161 * pcode.c: all pic16_pc_* hardware registers prefixed
6162 with underscore (_),
6163 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6164 * ralloc.c: newReg(): when register is REG_SFR then
6165 set address to rIdx,
6166 pic16_allocProcessorRegister(): marks register wasUsed=0
6167 pic16_writeUsedRegs(): added a call to assign processor
6168 registers via pic16_assignFixedRegisters
6170 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6172 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6173 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6174 variables in unused register banks. Also the SSEG is placed
6175 wherever there is enough space for it, and IDATA can be anywhere
6176 in internal RAM. For now compile using -Wl-Y[stack_size].
6177 The mem file is different for this option as well, since it
6178 makes no sense of talking about DSEG lenght.

7173 and JUMPTABLE iCodes properly now (worked by accident before)
7174 * src/mcs51/gen.c (leftRightUseAcc),
7175 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7176 iCode properly now. Use getSize instead of nRegs since a & b
7177 aren't part of the nRegs tally.
7179 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7181 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7182 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7183 before instructions that use the _STATUS register
7185 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7187 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7188 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7189 fetching of the pointer
7190 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7191 copied from genNearPointerSet()
7192 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7193 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7194 If they pop r0/r1 they must be called in the opposite order than aopOp().
7195 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7196 (resp. --stack-auto), prepared for --xstack
7198 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7202 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7204 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
7205 these ports have their own __sdcc_external_start()
7207 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7209 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7210 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7211 type for bits was changed. It resulted in bit variables becoming
7212 global, which is not permitted in PIC 14 assembly output.
7214 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7216 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7218 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7220 Z80 and MCS51 linkers complaint if a public symbol is defined
7221 in more than one library module:

7227 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7229 A few small changes that speed up the peephole optimizer.
7233 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7235 Try to make the peephole optimizer smarter by maintaining
7236 an association between the assembly source code and the
7237 iCodes that originated them. Put this information to use
7238 with a new peephole rule condition "notVolatile" so that
7239 the rules can be aggressive yet still safe.
7244 * src/mcs51/peeph.def
7246 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7250 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7251 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7252 if the left or right operand symbols have the accuse flag set.
7254 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7256 Changed the type of the result of the ! (NOT) operator to char;
7257 previously it returned the same type as the source. This allows
7258 us to eliminate all the genFloatNot functions (all of its target
7259 implementations were very buggy) since !float can use the same
7262 * src/SDCCicode.c (ast2iCode): ! returns char
7263 * src/mcs51/gen.c (genNot, genNotFloat),
7264 * src/ds390/gen.c (genNot, genNotFloat),
7265 * src/z80/gen.c (genNot, genNotFloat),
7266 * src/pic/gen.c (genNot, genNotFloat),
7267 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7269 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7271 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7272 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7273 during interrupts. Ensure WSAVE is located at a shared bank address.
7274 2. Fixed page selection in some places
7275 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7276 the registers name strings.
7277 4. Fixed "signed / unsigned compare" compiler warnings.
7278 5. The PIC port manages its own allocation of the general purpose
7279 registers, but makes no attempt to reuse them. As a result when
7280 compiling it soon runs out of general purpose registers. Some
7281 additional code was added to the files pcode.c and device.c to walk
7282 through the function call tree and rename the registers so that they
7292 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7293 genPlus() & genMinus() when the result is the same as left or right

7299 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7301 Made bitfield a distinct type from bit so that bitfields
7302 convert as per ANSI C and bits retain their traditional
7303 boolean style behaviour. Implemented bitfield support in
7311 * src/ds390/gen.c: bit v bitfield split
7312 * src/z80/gen.c: New support for bitfields
7313 * support/regression/tests/bitfields.c: reenabled z80,
7316 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7318 Rules 246.x, 247.x relate to bitfields, the others speed up
7319 access to xdata mapped I/O devices.
7321 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7323 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7325 Cleaned up genPackBits and genUnpackBits and added two helper
7326 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7327 for literal assignments in genPackBits (thanks to Frieder for
7333 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7335 Fixed bug #748310 (pointer to function type mishandled when the
7336 function name is omitted). Also fixed a SIGSEGV when a function
7337 attribute (reentrant, etc) is used on a non-function or on a
7338 function but misplaced before the parameter list.
7340 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7342 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7343 * support/Util/SDCCerr.h,
7344 * support/Util/SDCCerr.c: Added func attr misuse error msg

7365 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7367 Made the constant following the "interrupt" keyword optional. If
7368 omitted, the function will not automatically be given an entry
7369 in the interrupt vector table (similar to #pragma NOIV, but
7370 less syntacticly kludgy). The interrupt number is also now
7371 range checked. Also fixed a bug in the high order bit example
7378 * support/Util/SDCCerr.c
7379 * support/Util/SDCCerr.h
7382 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7385 * src/SDCCicode.c (operandOperation): rewritten some ops
7386 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7387 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7389 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7390 be re-activated by defining REDUCE_LITERALS)
7391 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7392 unsigned, but are signed by default
7393 * src/SDCCval.c (constVal): rearranged
7394 * src/SDCCval.c (valMod): preliminary fix
7395 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7438 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7439 * src/SDCCval.c (valDiv, valMod): fixed signdness
7440 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7441 signedness of modulo, left and right shift

7847 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7848 the regression tests I'm not brave enough to enable 245.b, 245.c
7849 * doc/sdccman.lyx: added latex preamble for hyperref package.
7850 Using pdflatex this will give you a hyperlinked pdf file with
7851 bookmarks. (prepend '%' before /usepackage if this breaks something)

7900 * src/SDCCmain.c: linkOptions is changed to set *,
7901 added if/endif conditional macros to remove options help
7902 messages from optionsTable when a port is not configured, added
7903 support for the PIc16 port in the ports table, when executing
7904 the compiler with no port specified on command line, a default
7905 port is selected with the new macro DEFAULT_PORT which is
7906 defined in port.h, in setDefaultOptions() linkOptions is removed
7907 from initialization assignment, since now it is a set,
7908 parseCmdLine uses setParseWithComma for linkOptions, in
7909 linkEdit() linkOptions are accessed with new function indexSet()
7910 which returns the i'th item of a set variable. See SDCCset.c, in
7911 linkEdit() when calling buildCmdLine(), added linkOptions as
7912 last argument. Now users can pass arguments to gplink via the
7913 -Wl option, main() uses pic16glue() to glue up pic16 programs

7925 * src/pic16/glue.c: commented out some error producing lines
7926 * src/pic16/main.c: __config directives are commented out to stop
7927 gpasm complaining and test the linkage with gplink, _linkCmd and
7928 _asmCmd changed to be more gplink and gpasm friendly
7929 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7930 produced an error when parsed, peep rule 12 is added to utilize
7931 movff, but it is commented out since the pCode does not support
7932 yet a command with 2 address arguments
7934 2003-05-18 <johan AT balder>
7936 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7937 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7963 2003-05-11 Borut Razem <borut.razem AT siol.net>
7965 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7966 the path of bin directory, so that PATH is the only env. variable, which has to be set
7967 in case of standard installation.
7968 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8997 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8999 * in \sdcc\as\mcs51\ changed these files in order to create an
9000 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9001 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9002 following files to include the previous two files: aslink.dsp,
9003 Makefile.aslink, Makefile.bcc, and Makefile.in.
9005 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9006 .adb instead of .cdb
9008 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9010 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9011 value from option --iram-size.
9013 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9015 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9018 2002-09-18 <wiml AT hhhh.org>
9020 * SDCClrange.h: exposed setFromRange() and setToRange()
9021 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9022 packRegsForAccUse() (bug 542397)
9023 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9024 multiple times and emitting the fetch operations more than once
9025 added aopGetUsesAcc() function to allow binary operators to
9026 fetch their operands in the correct order; made genMinus() emit
9027 compact code for X = LITERAL - Y
9029 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9030 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9031 sprintf() in line 1267.
9033 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9034 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9037 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9038 Changes to aslink (All the changes are marked with 'JCF'):
9040 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9043 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9044 area BSEG. Also moves, if possible, the DATA area down into the internal
9045 ram so more space is available.
9047 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9050 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9051 not bytes. Function summary() which creates a memory usage summary
9052 file with extension .mem. Reports of overlaping stack and small stack
9053 size. If the space for the stack is less than 16 bytes aslink trows a
9056 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9057 the 8051. Option 'y' for memory summary output file.
9059 Changes to sdcc (All the changes are marked with 'JCF'):
9061 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9063 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9064 overlaying area for it (uses RegBankUsed[4]).
9066 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9067 bank zero as used by default. By default aslink locates the stack
9068 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9069 the creation of the .mem file. Delegates the allocation of data area
9070 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9071 the begining of the stack area to aslink.
9073 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9074 glue() in SDCCglue.c creates an area for it.
9076 2002-09-03 Borut Razem <borut.razem AT siol.net>
9077 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9078 sdcc/src/pic/glue.c:
9079 introduced atexit() handler for teporay files removal in case of
9080 errors, assertions, ...
9082 2002-08-29 Borut Razem <borut.razem AT siol.net>
9083 * sdcc/support/cpp2/auto-host_vc_in.h:
9084 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9085 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9086 Maybe there is a similar problem with BORLANDC? It should be checked!
9088 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9089 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9090 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9091 was not executed, and the compiler (cl) launched a warning:
9092 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9094 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9102 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9103 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9104 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9105 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9106 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9107 - added Release configuration in VS projects
9108 - review of compiler an linker options
9109 - VC .exe files are generated in bin_vc directory, not to interfere
9110 with binaries generated from other projects (cygwin, mingw, bcc ...)
9112 * sdcc/src/yacc.dsp: added
9114 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9115 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9116 and insert the version number definitions from .version
9118 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9120 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9130 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9132 2002-08-10 Borut Razem <borut.razem AT siol.net>
9133 * src/SDCCmain.c (main):
9134 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9135 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9136 The consequence was that some temporary files were not removed.
9139 unification of code in functions tempfilename() and tempfile():
9140 function tempnam() is defined in Visual Studio 6.0 and .NET
9142 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9144 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9145 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

9159 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9160 added return 0 statements after assert() to make compiler happy
9162 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9163 added newline in the def file to keep MSC compiler satisfied
9165 * sdcc/src/z80/gen.c:
9166 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9167 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9168 - solved MSC error in function aopDump()
9170 * sdcc_vc.h: define PREFIX as "\\sdcc"
9172 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9227 Compiler generated registers for interrupt context saving
9228 were not getting allocated.
9230 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9233 Fixed left shift. Will promote the left side of a left shift
9234 if a) left shifting more than size of operand or b) when assigned
9235 to something size > size of left side
9237 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9347 * sdcc/src/SDCCloop.c:
9348 Previous fix was not good. basic blocks that have "break" or "return" are
9349 not really partof a loop , but live ranges used in these blocks should
9350 be live thru the entire loop, so set partOfLoop but don't add them to
9353 2002-02-21 <johan AT FRIJA>
