1866 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1867 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1868 always available in leading double underscore form. The C99 support is
1869 mostly missing, but it's a start.
1870 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1949 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1951 * device/lib/printf_large.c: removed inline assembly for portability and
1952 readability. Use printf_fast if speed or size are more important.
1953 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1954 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1956 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1958 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1959 prevent compiler warning
1961 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1963 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1964 moved to level 0 and declared as static. Also they are explicit
1965 placed in access bank. This was necessery because some times they
1966 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1967 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1968 optimizations. Currently only compare to unsigned char is implemented,
1969 * src/pic16/gen.c: added fReturnIdx array,
1970 * (struct resolvedIfx) is moved to gen.h and made public,
1971 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1972 * (aopForSym): added an optimization to directly store in stack of
1973 the operand of a SEND iCode,
1974 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1975 but as registers instead (AOP_REG) using the fReturnIdx array,
1976 * (pic16_freeAsmop): remove the freed register from the
1977 _G.sregsAlloc field,
1978 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1979 a compare of 'WREG',
1980 * (pic16_popGetTempRegCond): changed function prototype, now
1981 function takes also a bitVector argument v which holds the current
1982 set of registers that are allocated for stack access by aopForSym,
1983 registers allocated in aopForSym for accessing stack symbols are not
1984 any more part of the functions usedRegs field,
1985 * (genCall): some times aopOp is called for a stack variable to be
1986 send, aopForSym might perform the push, if this is true make sure
1987 that genCall doesn't push the variable twice by testing _G.resDirect,
1988 * (genFunction): changed testing for unspecified interrupt number
1989 from 256 to INTNO_UNSPEC,
1990 * modified selection scheme of frame pointer generation. Previously
1991 if function did use local registers a frame pointer was generated,
1992 now a frame pointer is generated only if function has arguments
1993 (that need PLUSW2 register access), or has stack arguments, or the
1994 compiler is not instructed to omit the frame pointer,
1995 * (genEndFunction): before restoring local registers that were saved
1996 in the function preamble, also restore the registers that *might*
1997 have been allocated for stack access,
1998 * (genRet): removed some old comments,
1999 * (genCmp, the active (RN's) version): added a call to the
2000 pic16_genCmp_special function to perform the compare with a more
2001 robust and optimized way,
2002 * (genInline): a feature has been added in inline code generation,
2003 which allows a wildcard variable substitution when writing inline
2004 assembly. Code is incomplete and experimental therefore undocumented,
2005 * (genCast): changed order of aopOp for result and right to allow
2006 aopForSym to directly load the result if possible,
2007 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2008 perform an optimized compare on some selected special occasions,
2009 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2010 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2011 generate an IVT any more,
2012 * src/pic16/main.c (pic16_optionsTable): added command line option
2014 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2015 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2017 * src/pic16/NOTES: Raphael Neider added in list of active developers
2018 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2019 jumptable_end to prevent bug #,
2020 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2021 inCond and outCond fields,
2022 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2023 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2024 turn off register spilling,
2025 * (packRegsForOneUse): synced with other ports' versions although it
2026 is not used currently,
2027 * (pic16_packRegisters): added an optimization while reading
2028 structure bitfields, some registers may be saved (malloc code is
2029 decreased by 80 bytes)
2031 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2033 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2034 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2035 this can be optimized more?
2037 2005-03-10 Raphael Neider <rneider AT web.de>
2039 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2040 genNearPointerGet): (hopefully) fixed access to bitfields via
2041 pointers (p->bitN = x; and x = p->bitN; failed)

2675 Adding support for replacing ljmps with sjmps in jumptables
2676 generated for switch statements. For now you need to set the
2677 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2678 Now 4 algorithms for mcs51 jumptable generation are used:
2679 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2680 addresses loaded pc-relative for up to 112 cases and stack-pushing
2681 target addresses loaded with offset from dptr for up to 256 cases.
2683 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2684 * src/mcs51/main.c: adapted constants for switch table generation

2711 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2713 * added libc directory. The current version of LibC contains string
2714 functions, ctype functions and macros and some functions of the
2715 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2716 be extensively tested in the future. Standard disclaimer here.
2717 Library is not automatically build yet. But one can build it by
2718 invoking 'make' inside the libc directory.
2719 * added ADC library under libio. Preliminary version yet.

2728 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2729 * (pic16_storeForReturn): optimized return of 0,
2730 * (genCmp): experimental code for new genCmp which uses PIC18's
2731 special compare&skip instructions. Initial tests fail some times
2732 with variables grater than 1 byte in size, so new code is disabled,
2733 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2735 * (genCast): began a fix to optimize the casting of a bit to another
2736 bit, now assigning a bitfield to another bitfield will fail, sorry,
2737 * src/pic16/main.c: disabled the use of lr-support feature,
2738 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2741 bits with offset (case PO_GPR_BIT),
2742 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2744 * (isBankInstruction): modified to return 0 for no banking instruction,
2745 and 1 for banking instruction,
2746 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2747 caused stop processing pCodes after a inline assembly block,
2748 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2749 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2750 registers when it shouldn't,
2751 * src/pic16/ralloc.c (allocReg): add preliminary support for
2752 supporting a limited set of temporary registers,
2754 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2756 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2757 genDataPointerSet): ensure assignments always copy in MSB to LSB
2759 (loadRegFromAop): recognize CLRH optimization,
2760 (genFunction): optimize RECEIVE iCodes in reentrant functions
2762 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2764 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5683 * src/SDCCval.c: updated call of decorateType()
5684 (valBitwise): fixed bug #882876
5685 (valMinus): added promotion
5686 (valLogicAndOr): result is unsigned
5687 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5688 * src/SDCCsymt.c (computeType),
5689 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5690 must not cause an unsigned operation
5691 * src/pic/glue (pic14emitRegularMap),
5692 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5694 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
5696 * src/pic/pcode.c (PCodeID): commented out left over debug code
5698 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
5700 * support/valdiag/tests/overflow.c: added shift tests
5708 * src/pic/pcodepeep.c,
5709 * src/pic/pcoderegs.c,
5711 * src/pic/ralloc.h: applied patch from Slade Rich;
5712 added support for multiple code pages and multiple RAM banks on the
5713 PIC 14 port. The ASM files now no longer simply assume all the
5714 code / RAM are in the same page / bank. This means the linker can
5715 safely allocate code/RAM of separate ASM files to different pages/banks.
5716 * doc/sdccman.lyx: added Slade's tips
5717 * src/mcs51/peeph.def: fixed bug #880768

5726 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5729 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5730 strtof is not part of C89 and isn't included with Mac OS X.
5732 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5734 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5759 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5761 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5762 loaded with the linker search paths (-L arguments) and the libraries
5763 to be linked with the current source (-l arguments). Changes
5764 currently will affect only the pic16 port.
5765 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5766 include path the port specific paths and port specific libraries,
5767 * gplink command now contains the $3 argument,
5768 * src/pic16/device.h,
5769 * src/pic16/device.c,: structure PIC_device is made public and
5770 renamed to PIC16_device, the same for variable Pics which is renamed
5771 to Pics16. Updated all references to them.

5783 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5785 Documenting changes from previous commits.
5786 * configure.in (version 1.56),
5787 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5788 when generating output files to configure the pic16 library,
5789 but now I've commented it out, since gputils aren't installed in the
5790 SF compile farm, so library won't compile
5792 * device/lib/Makefile.in (version 1.56): initially I've added in
5793 target 'all' the prerequestive 'model-pic16' so it compiled the
5794 pic16 library, but now I've commented it out for the same reasons
5796 * added targets 'model-pic16' and 'objects-pic16' to compile the
5798 * added target 'port-specific-objects-pic16' to handle the
5799 generated libraries and copy them into the build/ directory
5800 * added target 'clean-intermediate-pic16' to clean intermediate
5801 files into pic16 directory
5802 * in target 'installdirs' added line to create directory pic16 in
5803 the installation path
5805 * device/include/Makefile.in (version 1.11): in target 'install'
5806 added lines to copy all header files to installation path,
5807 * in target 'installdirs' added line create directory for pic16
5808 headers in the installation path

5823 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5824 option so that it actually works. Made it specific to the z80, since
5825 the gbz80 doesn't have these kinds of I/O ports.
5827 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5829 * device/include/z180.h,

5851 Mainly changes to support compilation of the device libraries
5852 * src/pic16/device.c: stack is allocated via symbol and not
5853 via literal number. The symbol is placed in the corresponding
5854 position of the data ram
5855 * (pic16_dump_section): relocatable and absolute uninitialized
5856 data are now emitted in sorted order to reduce section naming,
5857 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5858 weren't marked as being in the access bank,
5860 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5862 Added portion of GNU PIC Library under the directory
5863 device/include/pic16 and device/lib/pic16. These files
5864 contain the declarations of SFRs for the PIC18Fxx2 devices.
5865 The directory is initialized via configure from toplevel.
5867 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5869 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5881 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5883 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
5884 in simpler and even better code

5895 all over. Telling LaTeX to be less strict with word spacing
5896 to better keep the right margin. Changed some notes about
5897 maintainance of the ports in section 3.2.1 - is it OK like this?
5899 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5937 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5939 * src/pic16/peeph.def: all peepholes with movff are commented out,
5940 because there is a problem in the pcode peep optimizer,
5941 * src/pic16/ralloc.c: the register allocator can now reuse local

6058 A python script to validate compiler diagnostic messages. It can be
6059 used to verify that sdcc complains about bad c source code and
6060 gives a good location of the error.
6061 * support/valdiag/Makefile,
6062 * support/valdiag/valdiag.py,
6063 * support/valdiag/tests/*

6080 Bug reported from Jesus Calvino-Fraga
6082 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6084 * sdcc.spec: updated
6085 * device/include/Makefile.in: don't install CVS directories

6088 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6089 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6090 * src/ds390/gen.c (genRightShift): fixed bug #870788
6091 * src/SDCCast.c (decorateType): fixed bug #870781
6093 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6095 PIC16 port related changes:
6096 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6097 added variable stackPos,
6099 * gen.c: genCall, assignResultValue: added support for
6100 pushing/retrieving function parameters to/from stack,
6101 genFunction,genEndFunction: setup stack frame for the
6103 genAddrOf: will be changed according to bug 863624
6105 * added files genutils.c and genutils.h which contain gen*
6106 debugged and optimised functions extracted from gen.c
6108 * glue.c: added variable 'externs' which holds extern symbols,
6109 pic16emitRegularMap: is modified to properly handle relocatable
6110 symbols under the new scheme,
6111 pic16createInterruptVect: is modified
6112 pic16printPublics: is modified to emit 'global' assembler directives,
6113 added pic16_printExterns to print extern symbols,
6114 pic16glue: initializes stack/frame pointer in the beginning of
6115 the assembly output. Temporary hack, will be corrected later,
6116 because gplink yet does not support stack and SDCC does not
6117 yet support a type of crt0.o object to create the final binary.
6119 * Removed many lines that contain 8051 legacy code.
6120 * The code is finally placed under a 'code' directive.
6121 * Added port specific options.
6123 * _process_pragma: simplified since now we do not need *special*
6124 include file to define SFR registers. But a separate header
6125 will be needed. This will be developed later.
6126 * _pic16_parseOptions: added, parses port specific options:
6127 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6128 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6129 --preplace-udata-with=
6131 * _pic16_setDefaultOptions: modified to initialize section names,
6132 but hack is temporarly out of order since it needs improvement.
6133 * _pic16_genAssemblerPreamble: configuration words are emitted by
6134 their address instead of their name. This part is incomplete and
6135 supports only the 18Fxx2 devices. Other devices will emit an error
6136 during assembly since they do not contain the same set of config
6138 * _pic16_genIVT: is modified,
6140 * pcode.c: added definitions for some hardware registers that are needed
6142 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6143 All PCI entries are updated. Now LFSR is supported.
6144 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6145 * added pic16_newpCodeOpLit2 to support instructions with
6146 two literal arguments
6147 * pic16_pCode2str: corrected code that emits assembler instructions
6148 with two literal operands and those that have an access bit modifier
6149 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6150 this fixes a bug which caused some labels to be lost, when an
6151 assembler directive was added, i.e. banksel,
6152 * pic16_FixRegisterBanking: improved logic that causes the insertion
6154 * InlineFunction: functions that are called once, are not any more
6155 inlined. This can be a port option in the future,
6157 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6159 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6160 hold the corresponding uninitialized symbols,
6161 * pic16_allocProcessorRegister: registers have explicit marked the
6163 * pic16_allocInternalRegister: registers are explicit marked as
6165 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6166 processing list, so bit registers were lost,
6169 * ralloc.h: added field 'accessBank' and original symbol operand
6170 in register definition,
6171 * removed the field isMapped from register definition,
6173 ** Several functions have been removed from various sources:
6174 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6175 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6176 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6177 pic16_assignRelocatableRegisters
6179 ** others have been introduced:
6180 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6181 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6183 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6185 * support/scripts/inc2h.pl: changed definition of BIT_AT
6186 to emit 'sbit at' instead of 'bit at'. This was a request.
6188 PIC16 port related preliminary changes:
6189 * gen.c: prefixed function popRegFromString with
6190 pic16_ and all references to it corrected
6191 * pcode.c: all pic16_pc_* hardware registers prefixed
6192 with underscore (_),
6193 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6194 * ralloc.c: newReg(): when register is REG_SFR then
6195 set address to rIdx,
6196 pic16_allocProcessorRegister(): marks register wasUsed=0
6197 pic16_writeUsedRegs(): added a call to assign processor
6198 registers via pic16_assignFixedRegisters
6200 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6202 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6203 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6204 variables in unused register banks. Also the SSEG is placed
6205 wherever there is enough space for it, and IDATA can be anywhere
6206 in internal RAM. For now compile using -Wl-Y[stack_size].
6207 The mem file is different for this option as well, since it
6208 makes no sense of talking about DSEG lenght.
6210 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6212 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6459 it breaks with bitfields, extern declarations, and gcse analysis.
6460 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6461 could be assigned through a pointer, so don't complain.

7203 and JUMPTABLE iCodes properly now (worked by accident before)
7204 * src/mcs51/gen.c (leftRightUseAcc),
7205 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7206 iCode properly now. Use getSize instead of nRegs since a & b
7207 aren't part of the nRegs tally.
7209 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7211 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7217 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7218 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7219 fetching of the pointer
7220 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7221 copied from genNearPointerSet()
7222 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7223 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7224 If they pop r0/r1 they must be called in the opposite order than aopOp().
7225 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7226 (resp. --stack-auto), prepared for --xstack

7237 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7239 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7240 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7241 type for bits was changed. It resulted in bit variables becoming
7242 global, which is not permitted in PIC 14 assembly output.
7244 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7246 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7248 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7250 Z80 and MCS51 linkers complaint if a public symbol is defined
7251 in more than one library module:

7257 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7259 A few small changes that speed up the peephole optimizer.
7263 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7265 Try to make the peephole optimizer smarter by maintaining
7266 an association between the assembly source code and the
7267 iCodes that originated them. Put this information to use
7268 with a new peephole rule condition "notVolatile" so that
7269 the rules can be aggressive yet still safe.
7274 * src/mcs51/peeph.def
7276 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7280 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7281 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7282 if the left or right operand symbols have the accuse flag set.
7284 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7286 Changed the type of the result of the ! (NOT) operator to char;
7287 previously it returned the same type as the source. This allows
7288 us to eliminate all the genFloatNot functions (all of its target
7289 implementations were very buggy) since !float can use the same
7292 * src/SDCCicode.c (ast2iCode): ! returns char
7293 * src/mcs51/gen.c (genNot, genNotFloat),
7294 * src/ds390/gen.c (genNot, genNotFloat),
7295 * src/z80/gen.c (genNot, genNotFloat),
7296 * src/pic/gen.c (genNot, genNotFloat),
7297 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7299 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7301 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7302 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7303 during interrupts. Ensure WSAVE is located at a shared bank address.
7304 2. Fixed page selection in some places
7305 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7306 the registers name strings.
7307 4. Fixed "signed / unsigned compare" compiler warnings.
7308 5. The PIC port manages its own allocation of the general purpose
7309 registers, but makes no attempt to reuse them. As a result when
7310 compiling it soon runs out of general purpose registers. Some
7311 additional code was added to the files pcode.c and device.c to walk
7312 through the function call tree and rename the registers so that they
7322 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7323 genPlus() & genMinus() when the result is the same as left or right

7329 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7331 Made bitfield a distinct type from bit so that bitfields
7332 convert as per ANSI C and bits retain their traditional
7333 boolean style behaviour. Implemented bitfield support in
7341 * src/ds390/gen.c: bit v bitfield split
7342 * src/z80/gen.c: New support for bitfields
7343 * support/regression/tests/bitfields.c: reenabled z80,
7346 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7348 Rules 246.x, 247.x relate to bitfields, the others speed up
7349 access to xdata mapped I/O devices.
7351 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7353 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7355 Cleaned up genPackBits and genUnpackBits and added two helper
7356 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7357 for literal assignments in genPackBits (thanks to Frieder for
7363 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7365 Fixed bug #748310 (pointer to function type mishandled when the
7366 function name is omitted). Also fixed a SIGSEGV when a function
7367 attribute (reentrant, etc) is used on a non-function or on a
7368 function but misplaced before the parameter list.
7370 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7372 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7373 * support/Util/SDCCerr.h,
7374 * support/Util/SDCCerr.c: Added func attr misuse error msg

7395 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7397 Made the constant following the "interrupt" keyword optional. If
7398 omitted, the function will not automatically be given an entry
7399 in the interrupt vector table (similar to #pragma NOIV, but
7400 less syntacticly kludgy). The interrupt number is also now
7401 range checked. Also fixed a bug in the high order bit example

7415 * src/SDCCicode.c (operandOperation): rewritten some ops
7416 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7417 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7419 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7420 be re-activated by defining REDUCE_LITERALS)
7421 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7422 unsigned, but are signed by default
7423 * src/SDCCval.c (constVal): rearranged
7424 * src/SDCCval.c (valMod): preliminary fix
7425 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7468 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7469 * src/SDCCval.c (valDiv, valMod): fixed signdness
7470 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7471 signedness of modulo, left and right shift

7877 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7878 the regression tests I'm not brave enough to enable 245.b, 245.c
7879 * doc/sdccman.lyx: added latex preamble for hyperref package.
7880 Using pdflatex this will give you a hyperlinked pdf file with
7881 bookmarks. (prepend '%' before /usepackage if this breaks something)

7922 it can be defined with CFLAGS when running configure
7923 * src/SDCCmain.c: fixed compiling + linking with object files
7925 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7928 added --disable-pic16-port
7929 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7930 * src/SDCCmain.c: linkOptions is changed to set *,
7931 added if/endif conditional macros to remove options help
7932 messages from optionsTable when a port is not configured, added
7933 support for the PIc16 port in the ports table, when executing
7934 the compiler with no port specified on command line, a default
7935 port is selected with the new macro DEFAULT_PORT which is
7936 defined in port.h, in setDefaultOptions() linkOptions is removed
7937 from initialization assignment, since now it is a set,
7938 parseCmdLine uses setParseWithComma for linkOptions, in
7939 linkEdit() linkOptions are accessed with new function indexSet()
7940 which returns the i'th item of a set variable. See SDCCset.c, in
7941 linkEdit() when calling buildCmdLine(), added linkOptions as
7942 last argument. Now users can pass arguments to gplink via the
7943 -Wl option, main() uses pic16glue() to glue up pic16 programs

7955 * src/pic16/glue.c: commented out some error producing lines
7956 * src/pic16/main.c: __config directives are commented out to stop
7957 gpasm complaining and test the linkage with gplink, _linkCmd and
7958 _asmCmd changed to be more gplink and gpasm friendly
7959 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7960 produced an error when parsed, peep rule 12 is added to utilize
7961 movff, but it is commented out since the pCode does not support
7962 yet a command with 2 address arguments
7964 2003-05-18 <johan AT balder>
7966 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7993 2003-05-11 Borut Razem <borut.razem AT siol.net>
7995 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7996 the path of bin directory, so that PATH is the only env. variable, which has to be set
7997 in case of standard installation.

9094 overlaying area for it (uses RegBankUsed[4]).
9096 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9097 bank zero as used by default. By default aslink locates the stack
9098 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9099 the creation of the .mem file. Delegates the allocation of data area
9100 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9101 the begining of the stack area to aslink.
9103 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9104 glue() in SDCCglue.c creates an area for it.
9106 2002-09-03 Borut Razem <borut.razem AT siol.net>
9107 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9108 sdcc/src/pic/glue.c:
9109 introduced atexit() handler for teporay files removal in case of
9110 errors, assertions, ...
9112 2002-08-29 Borut Razem <borut.razem AT siol.net>
9113 * sdcc/support/cpp2/auto-host_vc_in.h:
9114 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9115 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9116 Maybe there is a similar problem with BORLANDC? It should be checked!
9118 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9119 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9120 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9121 was not executed, and the compiler (cl) launched a warning:
9122 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9124 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9125 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9127 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9128 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
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 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9133 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9134 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9135 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9136 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9137 - added Release configuration in VS projects
9138 - review of compiler an linker options
9139 - VC .exe files are generated in bin_vc directory, not to interfere
9140 with binaries generated from other projects (cygwin, mingw, bcc ...)
9142 * sdcc/src/yacc.dsp: added
9144 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9145 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9146 and insert the version number definitions from .version
9148 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9150 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9151 added - genarate auto-host.h using auto-host_vc_in.h as template
9154 removed from CVS, generated automatically
9156 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9157 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9159 2002-08-11 Borut Razem <borut.razem AT siol.net>
9160 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9162 2002-08-10 Borut Razem <borut.razem AT siol.net>
9163 * src/SDCCmain.c (main):
9164 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9165 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9166 The consequence was that some temporary files were not removed.
9169 unification of code in functions tempfilename() and tempfile():
9170 function tempnam() is defined in Visual Studio 6.0 and .NET
9172 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9174 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9175 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9176 - removed compiler command line option /WX: Treats all warnings as errors
9177 - update a list of source files, included into the project
9179 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9180 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9181 changed project type to Generic Project so that can be correcly converted to VS.NET project
9183 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9185 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9187 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9189 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9190 added return 0 statements after assert() to make compiler happy
9192 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9193 added newline in the def file to keep MSC compiler satisfied
9195 * sdcc/src/z80/gen.c:
9196 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9197 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9198 - solved MSC error in function aopDump()
9200 * sdcc_vc.h: define PREFIX as "\\sdcc"
9202 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9203 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9251 Added -p option. Allows port dependent processor to be specified.
9254 Initialized the new field char *Processor field to NULL in all ports
9257 Compiler generated registers for interrupt context saving
9258 were not getting allocated.
9260 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9263 Fixed left shift. Will promote the left side of a left shift
9264 if a) left shifting more than size of operand or b) when assigned
9265 to something size > size of left side
9267 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9375 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9377 * sdcc/src/SDCCloop.c:
9378 Previous fix was not good. basic blocks that have "break" or "return" are
9379 not really partof a loop , but live ranges used in these blocks should
9380 be live thru the entire loop, so set partOfLoop but don't add them to
9383 2002-02-21 <johan AT FRIJA>
9385 * src/SDCCcse.c: fixed bug #514308
9387 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9391 statement inside a loop, it was not being considered part of the loop.
9393 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9395 2002-02-10 Karl Bongers <karl AT turbobit.com>
9398 Fixed up SDCDB debugger somewhat. Updated debugger/README
9399 with lots of comments and notes.
9401 * device/examples/test2.c:
