1873 always available in leading double underscore form. The C99 support is
1874 mostly missing, but it's a start.
1875 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1954 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1956 * device/lib/printf_large.c: removed inline assembly for portability and
1957 readability. Use printf_fast if speed or size are more important.
1958 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1959 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1961 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1963 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1964 prevent compiler warning
1966 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1968 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1969 moved to level 0 and declared as static. Also they are explicit
1970 placed in access bank. This was necessery because some times they
1971 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1972 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1973 optimizations. Currently only compare to unsigned char is implemented,
1974 * src/pic16/gen.c: added fReturnIdx array,
1975 * (struct resolvedIfx) is moved to gen.h and made public,
1976 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1977 * (aopForSym): added an optimization to directly store in stack of
1978 the operand of a SEND iCode,
1979 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1980 but as registers instead (AOP_REG) using the fReturnIdx array,
1981 * (pic16_freeAsmop): remove the freed register from the
1982 _G.sregsAlloc field,
1983 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1984 a compare of 'WREG',
1985 * (pic16_popGetTempRegCond): changed function prototype, now
1986 function takes also a bitVector argument v which holds the current
1987 set of registers that are allocated for stack access by aopForSym,
1988 registers allocated in aopForSym for accessing stack symbols are not
1989 any more part of the functions usedRegs field,
1990 * (genCall): some times aopOp is called for a stack variable to be
1991 send, aopForSym might perform the push, if this is true make sure
1992 that genCall doesn't push the variable twice by testing _G.resDirect,
1993 * (genFunction): changed testing for unspecified interrupt number
1994 from 256 to INTNO_UNSPEC,
1995 * modified selection scheme of frame pointer generation. Previously
1996 if function did use local registers a frame pointer was generated,
1997 now a frame pointer is generated only if function has arguments
1998 (that need PLUSW2 register access), or has stack arguments, or the
1999 compiler is not instructed to omit the frame pointer,
2000 * (genEndFunction): before restoring local registers that were saved
2001 in the function preamble, also restore the registers that *might*
2002 have been allocated for stack access,
2003 * (genRet): removed some old comments,
2004 * (genCmp, the active (RN's) version): added a call to the
2005 pic16_genCmp_special function to perform the compare with a more
2006 robust and optimized way,
2007 * (genInline): a feature has been added in inline code generation,
2008 which allows a wildcard variable substitution when writing inline
2009 assembly. Code is incomplete and experimental therefore undocumented,
2010 * (genCast): changed order of aopOp for result and right to allow
2011 aopForSym to directly load the result if possible,
2012 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2013 perform an optimized compare on some selected special occasions,
2014 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2015 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2016 generate an IVT any more,
2017 * src/pic16/main.c (pic16_optionsTable): added command line option
2019 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2020 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2022 * src/pic16/NOTES: Raphael Neider added in list of active developers
2023 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2024 jumptable_end to prevent bug #,
2025 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2026 inCond and outCond fields,
2027 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2028 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2029 turn off register spilling,
2030 * (packRegsForOneUse): synced with other ports' versions although it
2031 is not used currently,
2032 * (pic16_packRegisters): added an optimization while reading
2033 structure bitfields, some registers may be saved (malloc code is
2034 decreased by 80 bytes)
2036 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2038 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2039 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2040 this can be optimized more?
2042 2005-03-10 Raphael Neider <rneider AT web.de>
2044 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2045 genNearPointerGet): (hopefully) fixed access to bitfields via
2046 pointers (p->bitN = x; and x = p->bitN; failed)

2680 Adding support for replacing ljmps with sjmps in jumptables
2681 generated for switch statements. For now you need to set the
2682 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2683 Now 4 algorithms for mcs51 jumptable generation are used:
2684 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2685 addresses loaded pc-relative for up to 112 cases and stack-pushing
2686 target addresses loaded with offset from dptr for up to 256 cases.

2713 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2714 to call when a stack overflow occurs,
2715 * (malloc.h): added CVS Id tag,
2716 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2718 * added libc directory. The current version of LibC contains string
2719 functions, ctype functions and macros and some functions of the
2720 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2721 be extensively tested in the future. Standard disclaimer here.
2722 Library is not automatically build yet. But one can build it by
2723 invoking 'make' inside the libc directory.
2724 * added ADC library under libio. Preliminary version yet.
2726 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2730 temporary registers, its a buggy feature and will be removed,
2731 * (pic16_popGet): set register instance field in AOP_CRY,
2732 * (pic16_outBitC): fixed for results in size greater than 1,
2733 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2734 * (pic16_storeForReturn): optimized return of 0,
2735 * (genCmp): experimental code for new genCmp which uses PIC18's
2736 special compare&skip instructions. Initial tests fail some times
2737 with variables grater than 1 byte in size, so new code is disabled,
2738 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2740 * (genCast): began a fix to optimize the casting of a bit to another
2741 bit, now assigning a bitfield to another bitfield will fail, sorry,
2742 * src/pic16/main.c: disabled the use of lr-support feature,
2743 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2746 bits with offset (case PO_GPR_BIT),
2747 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2749 * (isBankInstruction): modified to return 0 for no banking instruction,
2750 and 1 for banking instruction,
2751 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2752 caused stop processing pCodes after a inline assembly block,
2753 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2754 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2755 registers when it shouldn't,
2756 * src/pic16/ralloc.c (allocReg): add preliminary support for
2757 supporting a limited set of temporary registers,
2759 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2761 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2762 genDataPointerSet): ensure assignments always copy in MSB to LSB
2764 (loadRegFromAop): recognize CLRH optimization,
2765 (genFunction): optimize RECEIVE iCodes in reentrant functions
2767 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2769 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5685 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5686 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5687 see feature request #877103
5688 * src/SDCCval.c: updated call of decorateType()
5689 (valBitwise): fixed bug #882876
5690 (valMinus): added promotion
5691 (valLogicAndOr): result is unsigned
5692 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5693 * src/SDCCsymt.c (computeType),
5694 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
5695 must not cause an unsigned operation
5696 * src/pic/glue (pic14emitRegularMap),
5697 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
5699 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

5703 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
5705 * support/valdiag/tests/overflow.c: added shift tests
5713 * src/pic/pcodepeep.c,
5714 * src/pic/pcoderegs.c,
5716 * src/pic/ralloc.h: applied patch from Slade Rich;
5717 added support for multiple code pages and multiple RAM banks on the
5718 PIC 14 port. The ASM files now no longer simply assume all the
5719 code / RAM are in the same page / bank. This means the linker can
5720 safely allocate code/RAM of separate ASM files to different pages/banks.
5721 * doc/sdccman.lyx: added Slade's tips
5722 * src/mcs51/peeph.def: fixed bug #880768

5731 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
5734 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5735 strtof is not part of C89 and isn't included with Mac OS X.
5737 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5739 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5764 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5766 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5767 loaded with the linker search paths (-L arguments) and the libraries
5768 to be linked with the current source (-l arguments). Changes
5769 currently will affect only the pic16 port.
5770 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5771 include path the port specific paths and port specific libraries,
5772 * gplink command now contains the $3 argument,
5773 * src/pic16/device.h,
5774 * src/pic16/device.c,: structure PIC_device is made public and
5775 renamed to PIC16_device, the same for variable Pics which is renamed

5788 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5790 Documenting changes from previous commits.
5791 * configure.in (version 1.56),
5792 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5793 when generating output files to configure the pic16 library,
5794 but now I've commented it out, since gputils aren't installed in the
5795 SF compile farm, so library won't compile
5797 * device/lib/Makefile.in (version 1.56): initially I've added in
5798 target 'all' the prerequestive 'model-pic16' so it compiled the
5799 pic16 library, but now I've commented it out for the same reasons
5801 * added targets 'model-pic16' and 'objects-pic16' to compile the
5803 * added target 'port-specific-objects-pic16' to handle the
5804 generated libraries and copy them into the build/ directory
5805 * added target 'clean-intermediate-pic16' to clean intermediate
5806 files into pic16 directory
5807 * in target 'installdirs' added line to create directory pic16 in
5808 the installation path
5810 * device/include/Makefile.in (version 1.11): in target 'install'
5811 added lines to copy all header files to installation path,
5812 * in target 'installdirs' added line create directory for pic16
5813 headers in the installation path

5828 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5829 option so that it actually works. Made it specific to the z80, since
5830 the gbz80 doesn't have these kinds of I/O ports.
5832 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5834 * device/include/z180.h,

5856 Mainly changes to support compilation of the device libraries
5857 * src/pic16/device.c: stack is allocated via symbol and not
5858 via literal number. The symbol is placed in the corresponding
5859 position of the data ram
5860 * (pic16_dump_section): relocatable and absolute uninitialized
5861 data are now emitted in sorted order to reduce section naming,
5862 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5863 weren't marked as being in the access bank,
5865 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5867 Added portion of GNU PIC Library under the directory
5868 device/include/pic16 and device/lib/pic16. These files
5869 contain the declarations of SFRs for the PIC18Fxx2 devices.
5870 The directory is initialized via configure from toplevel.
5872 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5874 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5900 all over. Telling LaTeX to be less strict with word spacing
5901 to better keep the right margin. Changed some notes about
5902 maintainance of the ports in section 3.2.1 - is it OK like this?
5904 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5942 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5944 * src/pic16/peeph.def: all peepholes with movff are commented out,
5945 because there is a problem in the pcode peep optimizer,
5946 * src/pic16/ralloc.c: the register allocator can now reuse local

6098 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6100 PIC16 port related changes:
6101 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6102 added variable stackPos,
6104 * gen.c: genCall, assignResultValue: added support for
6105 pushing/retrieving function parameters to/from stack,
6106 genFunction,genEndFunction: setup stack frame for the
6108 genAddrOf: will be changed according to bug 863624
6110 * added files genutils.c and genutils.h which contain gen*
6111 debugged and optimised functions extracted from gen.c
6113 * glue.c: added variable 'externs' which holds extern symbols,
6114 pic16emitRegularMap: is modified to properly handle relocatable
6115 symbols under the new scheme,
6116 pic16createInterruptVect: is modified
6117 pic16printPublics: is modified to emit 'global' assembler directives,
6118 added pic16_printExterns to print extern symbols,
6119 pic16glue: initializes stack/frame pointer in the beginning of
6120 the assembly output. Temporary hack, will be corrected later,
6121 because gplink yet does not support stack and SDCC does not
6122 yet support a type of crt0.o object to create the final binary.
6124 * Removed many lines that contain 8051 legacy code.
6125 * The code is finally placed under a 'code' directive.
6126 * Added port specific options.
6128 * _process_pragma: simplified since now we do not need *special*
6129 include file to define SFR registers. But a separate header
6130 will be needed. This will be developed later.
6131 * _pic16_parseOptions: added, parses port specific options:
6132 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6133 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6134 --preplace-udata-with=
6136 * _pic16_setDefaultOptions: modified to initialize section names,
6137 but hack is temporarly out of order since it needs improvement.
6138 * _pic16_genAssemblerPreamble: configuration words are emitted by
6139 their address instead of their name. This part is incomplete and
6140 supports only the 18Fxx2 devices. Other devices will emit an error
6141 during assembly since they do not contain the same set of config
6143 * _pic16_genIVT: is modified,
6145 * pcode.c: added definitions for some hardware registers that are needed
6147 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6148 All PCI entries are updated. Now LFSR is supported.
6149 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6150 * added pic16_newpCodeOpLit2 to support instructions with
6151 two literal arguments
6152 * pic16_pCode2str: corrected code that emits assembler instructions
6153 with two literal operands and those that have an access bit modifier
6154 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6155 this fixes a bug which caused some labels to be lost, when an
6156 assembler directive was added, i.e. banksel,
6157 * pic16_FixRegisterBanking: improved logic that causes the insertion
6159 * InlineFunction: functions that are called once, are not any more
6160 inlined. This can be a port option in the future,
6162 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6164 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6165 hold the corresponding uninitialized symbols,
6166 * pic16_allocProcessorRegister: registers have explicit marked the
6168 * pic16_allocInternalRegister: registers are explicit marked as
6170 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6171 processing list, so bit registers were lost,
6174 * ralloc.h: added field 'accessBank' and original symbol operand
6175 in register definition,
6176 * removed the field isMapped from register definition,
6178 ** Several functions have been removed from various sources:

6190 * support/scripts/inc2h.pl: changed definition of BIT_AT
6191 to emit 'sbit at' instead of 'bit at'. This was a request.
6193 PIC16 port related preliminary changes:
6194 * gen.c: prefixed function popRegFromString with
6195 pic16_ and all references to it corrected
6196 * pcode.c: all pic16_pc_* hardware registers prefixed
6197 with underscore (_),
6198 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6199 * ralloc.c: newReg(): when register is REG_SFR then
6200 set address to rIdx,
6201 pic16_allocProcessorRegister(): marks register wasUsed=0
6202 pic16_writeUsedRegs(): added a call to assign processor
6203 registers via pic16_assignFixedRegisters
6205 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6207 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6208 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6209 variables in unused register banks. Also the SSEG is placed
6210 wherever there is enough space for it, and IDATA can be anywhere
6211 in internal RAM. For now compile using -Wl-Y[stack_size].
6212 The mem file is different for this option as well, since it
6213 makes no sense of talking about DSEG lenght.
6215 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6217 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6462 * src/SDCCast.c (decorateType): disabled a transformation I added in
6463 revision 1.188 (access to fields of a structure at an absolute address);
6464 it breaks with bitfields, extern declarations, and gcse analysis.
6465 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6466 could be assigned through a pointer, so don't complain.

7210 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7211 iCode properly now. Use getSize instead of nRegs since a & b
7212 aren't part of the nRegs tally.
7214 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7216 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7222 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7223 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7224 fetching of the pointer
7225 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7226 copied from genNearPointerSet()
7227 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7228 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7229 If they pop r0/r1 they must be called in the opposite order than aopOp().
7230 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7231 (resp. --stack-auto), prepared for --xstack

7242 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7244 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7245 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7246 type for bits was changed. It resulted in bit variables becoming
7247 global, which is not permitted in PIC 14 assembly output.
7249 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7251 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7253 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7255 Z80 and MCS51 linkers complaint if a public symbol is defined

7264 A few small changes that speed up the peephole optimizer.
7268 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7270 Try to make the peephole optimizer smarter by maintaining
7271 an association between the assembly source code and the
7272 iCodes that originated them. Put this information to use
7273 with a new peephole rule condition "notVolatile" so that
7274 the rules can be aggressive yet still safe.
7279 * src/mcs51/peeph.def
7281 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7285 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7286 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7287 if the left or right operand symbols have the accuse flag set.
7289 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7291 Changed the type of the result of the ! (NOT) operator to char;
7292 previously it returned the same type as the source. This allows
7293 us to eliminate all the genFloatNot functions (all of its target
7294 implementations were very buggy) since !float can use the same
7297 * src/SDCCicode.c (ast2iCode): ! returns char

7299 * src/ds390/gen.c (genNot, genNotFloat),
7300 * src/z80/gen.c (genNot, genNotFloat),
7301 * src/pic/gen.c (genNot, genNotFloat),
7302 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7304 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7306 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7307 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7308 during interrupts. Ensure WSAVE is located at a shared bank address.
7309 2. Fixed page selection in some places
7310 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7311 the registers name strings.
7312 4. Fixed "signed / unsigned compare" compiler warnings.
7313 5. The PIC port manages its own allocation of the general purpose
7314 registers, but makes no attempt to reuse them. As a result when
7315 compiling it soon runs out of general purpose registers. Some
7316 additional code was added to the files pcode.c and device.c to walk
7317 through the function call tree and rename the registers so that they
7327 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7328 genPlus() & genMinus() when the result is the same as left or right

7334 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7336 Made bitfield a distinct type from bit so that bitfields
7337 convert as per ANSI C and bits retain their traditional
7338 boolean style behaviour. Implemented bitfield support in
7346 * src/ds390/gen.c: bit v bitfield split
7347 * src/z80/gen.c: New support for bitfields
7348 * support/regression/tests/bitfields.c: reenabled z80,
7351 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7353 Rules 246.x, 247.x relate to bitfields, the others speed up
7354 access to xdata mapped I/O devices.
7356 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7358 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7360 Cleaned up genPackBits and genUnpackBits and added two helper
7361 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7362 for literal assignments in genPackBits (thanks to Frieder for
7368 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7370 Fixed bug #748310 (pointer to function type mishandled when the
7371 function name is omitted). Also fixed a SIGSEGV when a function
7372 attribute (reentrant, etc) is used on a non-function or on a
7373 function but misplaced before the parameter list.
7375 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7377 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7400 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7402 Made the constant following the "interrupt" keyword optional. If
7403 omitted, the function will not automatically be given an entry
7404 in the interrupt vector table (similar to #pragma NOIV, but
7405 less syntacticly kludgy). The interrupt number is also now
7406 range checked. Also fixed a bug in the high order bit example
7413 * support/Util/SDCCerr.c
7414 * support/Util/SDCCerr.h
7417 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7420 * src/SDCCicode.c (operandOperation): rewritten some ops
7421 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7422 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7424 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7425 be re-activated by defining REDUCE_LITERALS)
7426 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7427 unsigned, but are signed by default
7428 * src/SDCCval.c (constVal): rearranged
7429 * src/SDCCval.c (valMod): preliminary fix
7430 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7882 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7883 the regression tests I'm not brave enough to enable 245.b, 245.c
7884 * doc/sdccman.lyx: added latex preamble for hyperref package.
7885 Using pdflatex this will give you a hyperlinked pdf file with
7886 bookmarks. (prepend '%' before /usepackage if this breaks something)

7924 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7926 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7927 it can be defined with CFLAGS when running configure
7928 * src/SDCCmain.c: fixed compiling + linking with object files
7930 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7933 added --disable-pic16-port
7934 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7935 * src/SDCCmain.c: linkOptions is changed to set *,
7936 added if/endif conditional macros to remove options help
7937 messages from optionsTable when a port is not configured, added
7938 support for the PIc16 port in the ports table, when executing
7939 the compiler with no port specified on command line, a default
7940 port is selected with the new macro DEFAULT_PORT which is
7941 defined in port.h, in setDefaultOptions() linkOptions is removed
7942 from initialization assignment, since now it is a set,
7943 parseCmdLine uses setParseWithComma for linkOptions, in
7944 linkEdit() linkOptions are accessed with new function indexSet()
7945 which returns the i'th item of a set variable. See SDCCset.c, in
7946 linkEdit() when calling buildCmdLine(), added linkOptions as
7947 last argument. Now users can pass arguments to gplink via the
7948 -Wl option, main() uses pic16glue() to glue up pic16 programs

7960 * src/pic16/glue.c: commented out some error producing lines
7961 * src/pic16/main.c: __config directives are commented out to stop
7962 gpasm complaining and test the linkage with gplink, _linkCmd and
7963 _asmCmd changed to be more gplink and gpasm friendly
7964 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7965 produced an error when parsed, peep rule 12 is added to utilize
7966 movff, but it is commented out since the pCode does not support
7967 yet a command with 2 address arguments
7969 2003-05-18 <johan AT balder>
7971 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7998 2003-05-11 Borut Razem <borut.razem AT siol.net>
8000 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8001 the path of bin directory, so that PATH is the only env. variable, which has to be set
8002 in case of standard installation.
8003 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9096 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9098 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9099 overlaying area for it (uses RegBankUsed[4]).
9101 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9102 bank zero as used by default. By default aslink locates the stack
9103 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9104 the creation of the .mem file. Delegates the allocation of data area
9105 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9106 the begining of the stack area to aslink.
9108 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9109 glue() in SDCCglue.c creates an area for it.
9111 2002-09-03 Borut Razem <borut.razem AT siol.net>
9112 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9113 sdcc/src/pic/glue.c:
9114 introduced atexit() handler for teporay files removal in case of
9115 errors, assertions, ...
9117 2002-08-29 Borut Razem <borut.razem AT siol.net>
9118 * sdcc/support/cpp2/auto-host_vc_in.h:
9119 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9120 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9121 Maybe there is a similar problem with BORLANDC? It should be checked!
9123 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9124 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9125 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9126 was not executed, and the compiler (cl) launched a warning:
9127 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9129 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9130 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9132 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9133 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9135 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9136 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9137 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9138 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9139 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9140 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9141 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9142 - added Release configuration in VS projects
9143 - review of compiler an linker options
9144 - VC .exe files are generated in bin_vc directory, not to interfere
9145 with binaries generated from other projects (cygwin, mingw, bcc ...)
9147 * sdcc/src/yacc.dsp: added
9149 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9150 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9151 and insert the version number definitions from .version
9153 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9155 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9156 added - genarate auto-host.h using auto-host_vc_in.h as template
9159 removed from CVS, generated automatically
9161 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9162 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9164 2002-08-11 Borut Razem <borut.razem AT siol.net>
9165 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9167 2002-08-10 Borut Razem <borut.razem AT siol.net>
9168 * src/SDCCmain.c (main):
9169 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9170 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9171 The consequence was that some temporary files were not removed.
9174 unification of code in functions tempfilename() and tempfile():
9175 function tempnam() is defined in Visual Studio 6.0 and .NET
9177 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9179 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9180 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9181 - removed compiler command line option /WX: Treats all warnings as errors
9182 - update a list of source files, included into the project
9184 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9185 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9186 changed project type to Generic Project so that can be correcly converted to VS.NET project
9188 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9190 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9192 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9194 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9195 added return 0 statements after assert() to make compiler happy
9197 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9198 added newline in the def file to keep MSC compiler satisfied
9200 * sdcc/src/z80/gen.c:
9201 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9202 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9203 - solved MSC error in function aopDump()
9205 * sdcc_vc.h: define PREFIX as "\\sdcc"
9207 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9208 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9256 Added -p option. Allows port dependent processor to be specified.
9259 Initialized the new field char *Processor field to NULL in all ports
9262 Compiler generated registers for interrupt context saving
9263 were not getting allocated.
9265 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9268 Fixed left shift. Will promote the left side of a left shift
9269 if a) left shifting more than size of operand or b) when assigned
9270 to something size > size of left side
9272 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9380 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9382 * sdcc/src/SDCCloop.c:
9383 Previous fix was not good. basic blocks that have "break" or "return" are
9384 not really partof a loop , but live ranges used in these blocks should
9385 be live thru the entire loop, so set partOfLoop but don't add them to
9388 2002-02-21 <johan AT FRIJA>
9390 * src/SDCCcse.c: fixed bug #514308
9392 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9396 statement inside a loop, it was not being considered part of the loop.
9398 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9400 2002-02-10 Karl Bongers <karl AT turbobit.com>
