1779 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1780 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1781 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1782 always available in leading double underscore form. The C99 support is
1783 mostly missing, but it's a start.
1784 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1785 reserved identifier "__data".

1863 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1865 * device/lib/printf_large.c: removed inline assembly for portability and
1866 readability. Use printf_fast if speed or size are more important.
1867 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1868 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1870 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1872 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1873 prevent compiler warning
1875 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1877 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1878 moved to level 0 and declared as static. Also they are explicit
1879 placed in access bank. This was necessery because some times they
1880 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1881 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1882 optimizations. Currently only compare to unsigned char is implemented,
1883 * src/pic16/gen.c: added fReturnIdx array,
1884 * (struct resolvedIfx) is moved to gen.h and made public,
1885 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1886 * (aopForSym): added an optimization to directly store in stack of
1887 the operand of a SEND iCode,
1888 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1889 but as registers instead (AOP_REG) using the fReturnIdx array,
1890 * (pic16_freeAsmop): remove the freed register from the
1891 _G.sregsAlloc field,
1892 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1893 a compare of 'WREG',
1894 * (pic16_popGetTempRegCond): changed function prototype, now
1895 function takes also a bitVector argument v which holds the current
1896 set of registers that are allocated for stack access by aopForSym,
1897 registers allocated in aopForSym for accessing stack symbols are not
1898 any more part of the functions usedRegs field,
1899 * (genCall): some times aopOp is called for a stack variable to be
1900 send, aopForSym might perform the push, if this is true make sure
1901 that genCall doesn't push the variable twice by testing _G.resDirect,
1902 * (genFunction): changed testing for unspecified interrupt number
1903 from 256 to INTNO_UNSPEC,
1904 * modified selection scheme of frame pointer generation. Previously
1905 if function did use local registers a frame pointer was generated,
1906 now a frame pointer is generated only if function has arguments
1907 (that need PLUSW2 register access), or has stack arguments, or the
1908 compiler is not instructed to omit the frame pointer,
1909 * (genEndFunction): before restoring local registers that were saved
1910 in the function preamble, also restore the registers that *might*
1911 have been allocated for stack access,
1912 * (genRet): removed some old comments,
1913 * (genCmp, the active (RN's) version): added a call to the
1914 pic16_genCmp_special function to perform the compare with a more
1915 robust and optimized way,
1916 * (genInline): a feature has been added in inline code generation,
1917 which allows a wildcard variable substitution when writing inline
1918 assembly. Code is incomplete and experimental therefore undocumented,
1919 * (genCast): changed order of aopOp for result and right to allow
1920 aopForSym to directly load the result if possible,
1921 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1922 perform an optimized compare on some selected special occasions,
1923 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1924 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1925 generate an IVT any more,
1926 * src/pic16/main.c (pic16_optionsTable): added command line option
1928 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1929 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1931 * src/pic16/NOTES: Raphael Neider added in list of active developers
1932 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1933 jumptable_end to prevent bug #,
1934 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1935 inCond and outCond fields,
1936 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1937 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1938 turn off register spilling,
1939 * (packRegsForOneUse): synced with other ports' versions although it
1940 is not used currently,
1941 * (pic16_packRegisters): added an optimization while reading
1942 structure bitfields, some registers may be saved (malloc code is
1943 decreased by 80 bytes)
1945 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1947 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1948 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1949 this can be optimized more?
1951 2005-03-10 Raphael Neider <rneider AT web.de>
1953 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1954 genNearPointerGet): (hopefully) fixed access to bitfields via
1955 pointers (p->bitN = x; and x = p->bitN; failed)
1957 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2134 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2135 (sizeof(sectNames) changed to sizeof(sectName))

2142 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
2143 of (byte sized) temporaries (assign them to WREG for now)
2144 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2145 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2146 this might fix SIGSEGVs on MinGW...
2147 * src/SDCCopt.c (killDeadCode): restored original behaviour
2148 (volatile operands might get thrown away though)
2150 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2152 * src/pic16/gen.c: fixed bug #1106975,

2157 * added function attribute 'shadowregs' to take advantage of shadow
2159 * added function attribute 'wparam' as an alternative to the wparam

2589 Adding support for replacing ljmps with sjmps in jumptables
2590 generated for switch statements. For now you need to set the
2591 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2592 Now 4 algorithms for mcs51 jumptable generation are used:
2593 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2594 addresses loaded pc-relative for up to 112 cases and stack-pushing
2595 target addresses loaded with offset from dptr for up to 256 cases.
2597 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
2598 * src/mcs51/main.c: adapted constants for switch table generation
2599 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

2621 Large cummulative patch for pic16 port.
2622 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2623 to call when a stack overflow occurs,
2624 * (malloc.h): added CVS Id tag,
2625 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2627 * added libc directory. The current version of LibC contains string
2628 functions, ctype functions and macros and some functions of the
2629 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2630 be extensively tested in the future. Standard disclaimer here.
2631 Library is not automatically build yet. But one can build it by
2632 invoking 'make' inside the libc directory.
2633 * added ADC library under libio. Preliminary version yet.
2635 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2639 temporary registers, its a buggy feature and will be removed,
2640 * (pic16_popGet): set register instance field in AOP_CRY,

2642 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2643 * (pic16_storeForReturn): optimized return of 0,
2644 * (genCmp): experimental code for new genCmp which uses PIC18's
2645 special compare&skip instructions. Initial tests fail some times
2646 with variables grater than 1 byte in size, so new code is disabled,
2647 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2649 * (genCast): began a fix to optimize the casting of a bit to another
2650 bit, now assigning a bitfield to another bitfield will fail, sorry,
2651 * src/pic16/main.c: disabled the use of lr-support feature,
2652 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2653 * added some function prototypes, added function _debugf prototype,
2654 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2655 bits with offset (case PO_GPR_BIT),
2656 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2658 * (isBankInstruction): modified to return 0 for no banking instruction,
2659 and 1 for banking instruction,
2660 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2661 caused stop processing pCodes after a inline assembly block,
2662 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2663 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2664 registers when it shouldn't,
2665 * src/pic16/ralloc.c (allocReg): add preliminary support for
2666 supporting a limited set of temporary registers,
2668 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2670 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2671 genDataPointerSet): ensure assignments always copy in MSB to LSB
2673 (loadRegFromAop): recognize CLRH optimization,
2674 (genFunction): optimize RECEIVE iCodes in reentrant functions
2676 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2678 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2690 instead of sjmp to ret
2691 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2692 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2694 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5677 to be linked with the current source (-l arguments). Changes
5678 currently will affect only the pic16 port.
5679 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5680 include path the port specific paths and port specific libraries,

5687 initialization which bypassed the variable initializations block.
5689 * device/lib/pic16/Makefile.rules: removed --penable-stack from
5690 COMPILE_FLAGS and added the --nostdinc option
5692 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5699 Documenting changes from previous commits.
5700 * configure.in (version 1.56),
5701 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5702 when generating output files to configure the pic16 library,
5703 but now I've commented it out, since gputils aren't installed in the
5704 SF compile farm, so library won't compile
5706 * device/lib/Makefile.in (version 1.56): initially I've added in
5707 target 'all' the prerequestive 'model-pic16' so it compiled the
5708 pic16 library, but now I've commented it out for the same reasons
5710 * added targets 'model-pic16' and 'objects-pic16' to compile the
5712 * added target 'port-specific-objects-pic16' to handle the
5713 generated libraries and copy them into the build/ directory
5714 * added target 'clean-intermediate-pic16' to clean intermediate
5715 files into pic16 directory
5716 * in target 'installdirs' added line to create directory pic16 in
5717 the installation path
5719 * device/include/Makefile.in (version 1.11): in target 'install'
5720 added lines to copy all header files to installation path,
5721 * in target 'installdirs' added line create directory for pic16
5722 headers in the installation path
5724 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5737 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5738 option so that it actually works. Made it specific to the z80, since
5739 the gbz80 doesn't have these kinds of I/O ports.
5741 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5743 * device/include/z180.h,

5756 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5758 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5759 changed interrupt vector table generation to only emit declared vectors.
5760 * device/include/Makefile.in: added missing backslash
5761 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

5765 Mainly changes to support compilation of the device libraries
5766 * src/pic16/device.c: stack is allocated via symbol and not
5767 via literal number. The symbol is placed in the corresponding
5768 position of the data ram
5769 * (pic16_dump_section): relocatable and absolute uninitialized
5770 data are now emitted in sorted order to reduce section naming,
5771 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5772 weren't marked as being in the access bank,
5774 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5776 Added portion of GNU PIC Library under the directory
5777 device/include/pic16 and device/lib/pic16. These files
5778 contain the declarations of SFRs for the PIC18Fxx2 devices.
5779 The directory is initialized via configure from toplevel.
5781 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5783 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5784 the spilllocations to be compared correctly
5786 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5788 * src/SDCCast.c (decorateType): fixed bug introduced today
5790 2004-01-12 Borut Razem <borut.razem AT siol.net>

5808 * doc/sdccman.lyx: Moved and added some sections, small changes
5809 all over. Telling LaTeX to be less strict with word spacing
5810 to better keep the right margin. Changed some notes about
5811 maintainance of the ports in section 3.2.1 - is it OK like this?
5813 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5815 SDCC source changes:
5816 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5850 UPPER for immediate operands,
5851 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5853 * src/pic16/peeph.def: all peepholes with movff are commented out,
5854 because there is a problem in the pcode peep optimizer,
5855 * src/pic16/ralloc.c: the register allocator can now reuse local

5857 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5859 Added file src/pic16/NOTES with information about program writing on
5860 the current port version.

5892 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5895 * src/z80/main.c: added missed needLinkerScript flags (more than
5896 one port structure defined in these file)
5897 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5913 needLinkerScript flag
5915 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5916 * src/pic/glue.c: added variable udata_section_name to
5917 override default uninitialized data segment definition for

5919 * (pic14emitOverlay): modified to emit a commented overlay segment
5920 directive when no overlay data exist
5921 * (picglue): modified to emit uninitialized data segment
5922 according to udata_section_name

5932 2004-01-07 Borut Razem <borut.razem AT siol.net>
5934 * support/scripts/sdcc.nsi: update PATH
5935 * support/scripts/sdcc.ico: craeted

5948 include information about variables allocated to the overlay
5951 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5953 * as/mcs51/lkmain.c: Help about -Y option

5965 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5967 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5968 (default behaviour).
5970 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5972 A python script to validate compiler diagnostic messages. It can be
5973 used to verify that sdcc complains about bad c source code and
5974 gives a good location of the error.
5975 * support/valdiag/Makefile,
5976 * support/valdiag/valdiag.py,
5977 * support/valdiag/tests/*
5979 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5994 Bug reported from Jesus Calvino-Fraga
5996 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5998 * sdcc.spec: updated
5999 * device/include/Makefile.in: don't install CVS directories
6000 * device/lib/Makefile.in: added removal of CVS directories after install
6001 * doc/Makefile: fixed install, added local_icons
6002 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6003 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6004 * src/ds390/gen.c (genRightShift): fixed bug #870788
6005 * src/SDCCast.c (decorateType): fixed bug #870781
6007 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6009 PIC16 port related changes:
6010 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6011 added variable stackPos,
6013 * gen.c: genCall, assignResultValue: added support for
6014 pushing/retrieving function parameters to/from stack,
6015 genFunction,genEndFunction: setup stack frame for the
6017 genAddrOf: will be changed according to bug 863624
6019 * added files genutils.c and genutils.h which contain gen*
6020 debugged and optimised functions extracted from gen.c
6022 * glue.c: added variable 'externs' which holds extern symbols,
6023 pic16emitRegularMap: is modified to properly handle relocatable
6024 symbols under the new scheme,
6025 pic16createInterruptVect: is modified
6026 pic16printPublics: is modified to emit 'global' assembler directives,
6027 added pic16_printExterns to print extern symbols,
6028 pic16glue: initializes stack/frame pointer in the beginning of
6029 the assembly output. Temporary hack, will be corrected later,
6030 because gplink yet does not support stack and SDCC does not
6031 yet support a type of crt0.o object to create the final binary.
6033 * Removed many lines that contain 8051 legacy code.
6034 * The code is finally placed under a 'code' directive.
6035 * Added port specific options.
6037 * _process_pragma: simplified since now we do not need *special*
6038 include file to define SFR registers. But a separate header
6039 will be needed. This will be developed later.
6040 * _pic16_parseOptions: added, parses port specific options:
6041 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6042 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6043 --preplace-udata-with=
6045 * _pic16_setDefaultOptions: modified to initialize section names,
6046 but hack is temporarly out of order since it needs improvement.
6047 * _pic16_genAssemblerPreamble: configuration words are emitted by
6048 their address instead of their name. This part is incomplete and
6049 supports only the 18Fxx2 devices. Other devices will emit an error
6050 during assembly since they do not contain the same set of config
6052 * _pic16_genIVT: is modified,
6054 * pcode.c: added definitions for some hardware registers that are needed
6056 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6057 All PCI entries are updated. Now LFSR is supported.
6058 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6059 * added pic16_newpCodeOpLit2 to support instructions with
6060 two literal arguments
6061 * pic16_pCode2str: corrected code that emits assembler instructions
6062 with two literal operands and those that have an access bit modifier
6063 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6064 this fixes a bug which caused some labels to be lost, when an
6065 assembler directive was added, i.e. banksel,
6066 * pic16_FixRegisterBanking: improved logic that causes the insertion
6068 * InlineFunction: functions that are called once, are not any more
6069 inlined. This can be a port option in the future,
6071 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6073 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6074 hold the corresponding uninitialized symbols,
6075 * pic16_allocProcessorRegister: registers have explicit marked the
6077 * pic16_allocInternalRegister: registers are explicit marked as
6079 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6080 processing list, so bit registers were lost,
6083 * ralloc.h: added field 'accessBank' and original symbol operand
6084 in register definition,
6085 * removed the field isMapped from register definition,
6087 ** Several functions have been removed from various sources:
6088 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6089 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6090 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6091 pic16_assignRelocatableRegisters
6093 ** others have been introduced:
6094 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6095 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6097 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6099 * support/scripts/inc2h.pl: changed definition of BIT_AT
6100 to emit 'sbit at' instead of 'bit at'. This was a request.
6102 PIC16 port related preliminary changes:
6103 * gen.c: prefixed function popRegFromString with
6104 pic16_ and all references to it corrected
6105 * pcode.c: all pic16_pc_* hardware registers prefixed
6106 with underscore (_),
6107 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6108 * ralloc.c: newReg(): when register is REG_SFR then
6109 set address to rIdx,
6110 pic16_allocProcessorRegister(): marks register wasUsed=0
6111 pic16_writeUsedRegs(): added a call to assign processor
6112 registers via pic16_assignFixedRegisters
6114 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6116 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6117 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6118 variables in unused register banks. Also the SSEG is placed
6119 wherever there is enough space for it, and IDATA can be anywhere
6120 in internal RAM. For now compile using -Wl-Y[stack_size].
6121 The mem file is different for this option as well, since it
6122 makes no sense of talking about DSEG lenght.
6124 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6126 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6127 in certain cases, e.g. when ROM assignment, patch provided
6128 from Albert den Haan.
6130 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7173 A few small changes that speed up the peephole optimizer.
7177 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7179 Try to make the peephole optimizer smarter by maintaining
7180 an association between the assembly source code and the
7181 iCodes that originated them. Put this information to use
7182 with a new peephole rule condition "notVolatile" so that
7183 the rules can be aggressive yet still safe.
7188 * src/mcs51/peeph.def
7190 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7194 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7195 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7196 if the left or right operand symbols have the accuse flag set.
7198 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7200 Changed the type of the result of the ! (NOT) operator to char;
7201 previously it returned the same type as the source. This allows
7202 us to eliminate all the genFloatNot functions (all of its target
7203 implementations were very buggy) since !float can use the same
7206 * src/SDCCicode.c (ast2iCode): ! returns char
7207 * src/mcs51/gen.c (genNot, genNotFloat),
7208 * src/ds390/gen.c (genNot, genNotFloat),
7209 * src/z80/gen.c (genNot, genNotFloat),
7210 * src/pic/gen.c (genNot, genNotFloat),
7211 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

7215 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7216 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7217 during interrupts. Ensure WSAVE is located at a shared bank address.
7218 2. Fixed page selection in some places
7219 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7220 the registers name strings.
7221 4. Fixed "signed / unsigned compare" compiler warnings.
7222 5. The PIC port manages its own allocation of the general purpose
7223 registers, but makes no attempt to reuse them. As a result when
7224 compiling it soon runs out of general purpose registers. Some
7225 additional code was added to the files pcode.c and device.c to walk
7226 through the function call tree and rename the registers so that they
7236 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7237 genPlus() & genMinus() when the result is the same as left or right
7239 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7243 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7245 Made bitfield a distinct type from bit so that bitfields
7246 convert as per ANSI C and bits retain their traditional
7247 boolean style behaviour. Implemented bitfield support in
7255 * src/ds390/gen.c: bit v bitfield split
7256 * src/z80/gen.c: New support for bitfields
7257 * support/regression/tests/bitfields.c: reenabled z80,
7260 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7262 Rules 246.x, 247.x relate to bitfields, the others speed up
7263 access to xdata mapped I/O devices.
7265 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7267 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7269 Cleaned up genPackBits and genUnpackBits and added two helper
7270 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7271 for literal assignments in genPackBits (thanks to Frieder for
7277 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7279 Fixed bug #748310 (pointer to function type mishandled when the
7280 function name is omitted). Also fixed a SIGSEGV when a function
7281 attribute (reentrant, etc) is used on a non-function or on a
7282 function but misplaced before the parameter list.
7284 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7286 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7287 * support/Util/SDCCerr.h,

7309 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7311 Made the constant following the "interrupt" keyword optional. If
7312 omitted, the function will not automatically be given an entry
7313 in the interrupt vector table (similar to #pragma NOIV, but
7314 less syntacticly kludgy). The interrupt number is also now
7315 range checked. Also fixed a bug in the high order bit example

7329 * src/SDCCicode.c (operandOperation): rewritten some ops
7330 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7331 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7333 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7334 be re-activated by defining REDUCE_LITERALS)
7335 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7336 unsigned, but are signed by default
7337 * src/SDCCval.c (constVal): rearranged
7338 * src/SDCCval.c (valMod): preliminary fix
7339 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7382 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7383 * src/SDCCval.c (valDiv, valMod): fixed signdness
7384 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7385 signedness of modulo, left and right shift

7784 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7785 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7786 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
7789 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7791 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7792 the regression tests I'm not brave enough to enable 245.b, 245.c
7793 * doc/sdccman.lyx: added latex preamble for hyperref package.
7794 Using pdflatex this will give you a hyperlinked pdf file with
7795 bookmarks. (prepend '%' before /usepackage if this breaks something)

7807 * src/SDCCglue.c (printIval): fixed bug #739934
7809 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
7811 Applied patch from bug 737905 (renamed yylineo to mylineno):
7818 * src/pic16/pcode.c: Cleaned warnings
7819 * src/pic16/pcodeflow.c: Cleaned warnings
7820 * src/pic16/pcoderegs.c: Cleaned warnings

7833 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7835 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7836 it can be defined with CFLAGS when running configure
7837 * src/SDCCmain.c: fixed compiling + linking with object files
7839 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7841 * configure.in: configure for pic16 port,
7842 added --disable-pic16-port
7843 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7844 * src/SDCCmain.c: linkOptions is changed to set *,
7845 added if/endif conditional macros to remove options help
7846 messages from optionsTable when a port is not configured, added
7847 support for the PIc16 port in the ports table, when executing
7848 the compiler with no port specified on command line, a default
7849 port is selected with the new macro DEFAULT_PORT which is
7850 defined in port.h, in setDefaultOptions() linkOptions is removed
7851 from initialization assignment, since now it is a set,
7852 parseCmdLine uses setParseWithComma for linkOptions, in
7853 linkEdit() linkOptions are accessed with new function indexSet()
7854 which returns the i'th item of a set variable. See SDCCset.c, in
7855 linkEdit() when calling buildCmdLine(), added linkOptions as
7856 last argument. Now users can pass arguments to gplink via the
7857 -Wl option, main() uses pic16glue() to glue up pic16 programs
7858 * src/SDCCpeeph.c: various changes to support pic16
7859 * src/SDCCset.c: added function void *indexSet(set *, int) to

7867 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7869 * src/pic16/glue.c: commented out some error producing lines
7870 * src/pic16/main.c: __config directives are commented out to stop
7871 gpasm complaining and test the linkage with gplink, _linkCmd and
7872 _asmCmd changed to be more gplink and gpasm friendly
7873 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7874 produced an error when parsed, peep rule 12 is added to utilize
7875 movff, but it is commented out since the pCode does not support
7876 yet a command with 2 address arguments
7878 2003-05-18 <johan AT balder>
7880 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7881 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7882 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

7905 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7907 2003-05-11 Borut Razem <borut.razem AT siol.net>
7909 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7910 the path of bin directory, so that PATH is the only env. variable, which has to be set
7911 in case of standard installation.
7912 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8915 * src/SDCCicode.c: fixed array add
8917 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>

8919 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8921 2003-01-04 <johan AT balder>
8923 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8925 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8926 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8928 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8929 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8938 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8939 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8941 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8943 * in \sdcc\as\mcs51\ changed these files in order to create an
8944 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8945 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8946 following files to include the previous two files: aslink.dsp,
8947 Makefile.aslink, Makefile.bcc, and Makefile.in.
8949 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8950 .adb instead of .cdb
8952 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8954 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8955 value from option --iram-size.
8957 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8959 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8962 2002-09-18 <wiml AT hhhh.org>
8964 * SDCClrange.h: exposed setFromRange() and setToRange()
8965 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8966 packRegsForAccUse() (bug 542397)
8967 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8968 multiple times and emitting the fetch operations more than once
8969 added aopGetUsesAcc() function to allow binary operators to
8970 fetch their operands in the correct order; made genMinus() emit
8971 compact code for X = LITERAL - Y
8973 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8974 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8975 sprintf() in line 1267.
8977 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8978 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8981 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8982 Changes to aslink (All the changes are marked with 'JCF'):
8984 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8987 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8988 area BSEG. Also moves, if possible, the DATA area down into the internal
8989 ram so more space is available.
8991 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8994 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8995 not bytes. Function summary() which creates a memory usage summary
8996 file with extension .mem. Reports of overlaping stack and small stack
8997 size. If the space for the stack is less than 16 bytes aslink trows a
9000 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9001 the 8051. Option 'y' for memory summary output file.
9003 Changes to sdcc (All the changes are marked with 'JCF'):
9005 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9007 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9008 overlaying area for it (uses RegBankUsed[4]).
9010 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9011 bank zero as used by default. By default aslink locates the stack
9012 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9013 the creation of the .mem file. Delegates the allocation of data area
9014 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9015 the begining of the stack area to aslink.
9017 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9018 glue() in SDCCglue.c creates an area for it.
9020 2002-09-03 Borut Razem <borut.razem AT siol.net>
9021 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9022 sdcc/src/pic/glue.c:
9023 introduced atexit() handler for teporay files removal in case of
9024 errors, assertions, ...
9026 2002-08-29 Borut Razem <borut.razem AT siol.net>
9027 * sdcc/support/cpp2/auto-host_vc_in.h:
9028 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9029 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9030 Maybe there is a similar problem with BORLANDC? It should be checked!
9032 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9033 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9034 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9035 was not executed, and the compiler (cl) launched a warning:
9036 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9038 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9039 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9041 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

9047 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9048 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9049 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9050 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9051 - added Release configuration in VS projects
9052 - review of compiler an linker options
9053 - VC .exe files are generated in bin_vc directory, not to interfere
9054 with binaries generated from other projects (cygwin, mingw, bcc ...)
9056 * sdcc/src/yacc.dsp: added
9058 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9059 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9060 and insert the version number definitions from .version
9062 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9064 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9065 added - genarate auto-host.h using auto-host_vc_in.h as template
9068 removed from CVS, generated automatically
9070 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9071 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9073 2002-08-11 Borut Razem <borut.razem AT siol.net>
9074 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9076 2002-08-10 Borut Razem <borut.razem AT siol.net>
9077 * src/SDCCmain.c (main):
9078 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9079 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9080 The consequence was that some temporary files were not removed.
9083 unification of code in functions tempfilename() and tempfile():
9084 function tempnam() is defined in Visual Studio 6.0 and .NET
9086 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9088 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9089 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9090 - removed compiler command line option /WX: Treats all warnings as errors
9091 - update a list of source files, included into the project
9093 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9104 added return 0 statements after assert() to make compiler happy
9106 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9107 added newline in the def file to keep MSC compiler satisfied
9109 * sdcc/src/z80/gen.c:
9110 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9111 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9112 - solved MSC error in function aopDump()
9114 * sdcc_vc.h: define PREFIX as "\\sdcc"

9291 * sdcc/src/SDCCloop.c:
9292 Previous fix was not good. basic blocks that have "break" or "return" are
9293 not really partof a loop , but live ranges used in these blocks should
9294 be live thru the entire loop, so set partOfLoop but don't add them to
