896 * src/SDCCdflow.c (computeDataFlow),
898 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
900 * src/SDCCcflow.c (*),
902 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
903 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
904 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
905 immedDom() returning wrong block; probably fixes bug #1160833)
907 2005-03-20 Borut Razem <borut.razem AT siol.net>
909 * support/scripts/inc2h.pl: WIN32 port
911 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
913 * device/lib/makefile.in: added abs.c and labs.c
915 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
917 * device/include/stdint.h: added
918 * device/lib/abs.c: added
919 * device/lib/labs.c: added
920 * device/include/stdlib.h: added abs() and labs() prototypes
921 * device/lib/libsdcc.lib: added abs and labs
922 * device/include/float.h,
923 * device/lib/_fsmul.c,
924 * device/lib/printf_fast.c,
925 * device/lib/printf_tiny.c: updated comments
927 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
929 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
932 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
934 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
935 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
937 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
939 * device/lib/printf_large.c: removed inline assembly for portability and
940 readability. Use printf_fast if speed or size are more important.
941 * src/pic16/gen.c: removed conditions around use of DEBUGpc
942 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
944 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
946 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
947 prevent compiler warning
949 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
951 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
952 moved to level 0 and declared as static. Also they are explicit
953 placed in access bank. This was necessery because some times they
954 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
955 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
956 optimizations. Currently only compare to unsigned char is implemented,
957 * src/pic16/gen.c: added fReturnIdx array,
958 * (struct resolvedIfx) is moved to gen.h and made public,
959 * (struct _G): added sregsAlloc and sregsAllocSet fields,
960 * (aopForSym): added an optimization to directly store in stack of
961 the operand of a SEND iCode,
962 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
963 but as registers instead (AOP_REG) using the fReturnIdx array,
964 * (pic16_freeAsmop): remove the freed register from the
966 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
968 * (pic16_popGetTempRegCond): changed function prototype, now
969 function takes also a bitVector argument v which holds the current
970 set of registers that are allocated for stack access by aopForSym,
971 registers allocated in aopForSym for accessing stack symbols are not
972 any more part of the functions usedRegs field,
973 * (genCall): some times aopOp is called for a stack variable to be
974 send, aopForSym might perform the push, if this is true make sure
975 that genCall doesn't push the variable twice by testing _G.resDirect,
976 * (genFunction): changed testing for unspecified interrupt number
977 from 256 to INTNO_UNSPEC,
978 * modified selection scheme of frame pointer generation. Previously
979 if function did use local registers a frame pointer was generated,
980 now a frame pointer is generated only if function has arguments
981 (that need PLUSW2 register access), or has stack arguments, or the
982 compiler is not instructed to omit the frame pointer,
983 * (genEndFunction): before restoring local registers that were saved
984 in the function preamble, also restore the registers that *might*
985 have been allocated for stack access,
986 * (genRet): removed some old comments,
987 * (genCmp, the active (RN's) version): added a call to the
988 pic16_genCmp_special function to perform the compare with a more
989 robust and optimized way,
990 * (genInline): a feature has been added in inline code generation,
991 which allows a wildcard variable substitution when writing inline
992 assembly. Code is incomplete and experimental therefore undocumented,
993 * (genCast): changed order of aopOp for result and right to allow
994 aopForSym to directly load the result if possible,
995 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
996 perform an optimized compare on some selected special occasions,
997 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
998 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
999 generate an IVT any more,
1000 * src/pic16/main.c (pic16_optionsTable): added command line option
1002 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1003 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1005 * src/pic16/NOTES: Raphael Neider added in list of active developers
1006 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1007 jumptable_end to prevent bug #,
1008 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1009 inCond and outCond fields,
1010 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1011 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1012 turn off register spilling,
1013 * (packRegsForOneUse): synced with other ports' versions although it
1014 is not used currently,
1015 * (pic16_packRegisters): added an optimization while reading
1016 structure bitfields, some registers may be saved (malloc code is
1017 decreased by 80 bytes)
1019 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1021 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1022 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1023 this can be optimized more?
1025 2005-03-10 Raphael Neider <rneider AT web.de>
1027 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1028 genNearPointerGet): (hopefully) fixed access to bitfields via
1029 pointers (p->bitN = x; and x = p->bitN; failed)
1031 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1033 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1072 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1074 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1075 to keep the correct label reference count when adding/removing references
1076 to labels. A peephole file using this is appended to patch #1144962.

1218 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1219 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1220 this might fix SIGSEGVs on MinGW...
1221 * src/SDCCopt.c (killDeadCode): restored original behaviour
1222 (volatile operands might get thrown away though)
1224 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1307 * src/pic16/gen.c (pic16_sameRegs): relaxed size criterion
1308 * (genUminus): rewritten to for efficiency
1309 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
1310 used uninitialized in some cases)
1311 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
1312 copy the third byte from the int -- now assumes 0x80 (data memory)
1313 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping

1702 functions, ctype functions and macros and some functions of the
1703 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1704 be extensively tested in the future. Standard disclaimer here.

1718 * (genCmp): experimental code for new genCmp which uses PIC18's
1719 special compare&skip instructions. Initial tests fail some times
1720 with variables grater than 1 byte in size, so new code is disabled,
1721 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1723 * (genCast): began a fix to optimize the casting of a bit to another
1724 bit, now assigning a bitfield to another bitfield will fail, sorry,

1738 registers when it shouldn't,
1739 * src/pic16/ralloc.c (allocReg): add preliminary support for
1740 supporting a limited set of temporary registers,
1742 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1748 (genFunction): optimize RECEIVE iCodes in reentrant functions
1750 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1752 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4747 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4749 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4750 loaded with the linker search paths (-L arguments) and the libraries
4751 to be linked with the current source (-l arguments). Changes
4752 currently will affect only the pic16 port.
4753 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4754 include path the port specific paths and port specific libraries,
4755 * gplink command now contains the $3 argument,
4756 * src/pic16/device.h,
4757 * src/pic16/device.c,: structure PIC_device is made public and
4758 renamed to PIC16_device, the same for variable Pics which is renamed

4773 Documenting changes from previous commits.
4774 * configure.in (version 1.56),
4775 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4776 when generating output files to configure the pic16 library,
4777 but now I've commented it out, since gputils aren't installed in the
4778 SF compile farm, so library won't compile
4780 * device/lib/Makefile.in (version 1.56): initially I've added in
4781 target 'all' the prerequestive 'model-pic16' so it compiled the
4782 pic16 library, but now I've commented it out for the same reasons
4784 * added targets 'model-pic16' and 'objects-pic16' to compile the
4786 * added target 'port-specific-objects-pic16' to handle the
4787 generated libraries and copy them into the build/ directory
4788 * added target 'clean-intermediate-pic16' to clean intermediate
4789 files into pic16 directory
4790 * in target 'installdirs' added line to create directory pic16 in
4791 the installation path
4793 * device/include/Makefile.in (version 1.11): in target 'install'
4794 added lines to copy all header files to installation path,
4795 * in target 'installdirs' added line create directory for pic16
4796 headers in the installation path

4811 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4812 option so that it actually works. Made it specific to the z80, since
4813 the gbz80 doesn't have these kinds of I/O ports.
4815 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4817 * device/include/z180.h,

4841 via literal number. The symbol is placed in the corresponding
4842 position of the data ram
4843 * (pic16_dump_section): relocatable and absolute uninitialized
4844 data are now emitted in sorted order to reduce section naming,
4845 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4846 weren't marked as being in the access bank,
4848 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4850 Added portion of GNU PIC Library under the directory
4851 device/include/pic16 and device/lib/pic16. These files
4852 contain the declarations of SFRs for the PIC18Fxx2 devices.
4853 The directory is initialized via configure from toplevel.

4882 * doc/sdccman.lyx: Moved and added some sections, small changes
4883 all over. Telling LaTeX to be less strict with word spacing
4884 to better keep the right margin. Changed some notes about
4885 maintainance of the ports in section 3.2.1 - is it OK like this?
4887 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4889 SDCC source changes:
4890 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4924 UPPER for immediate operands,
4925 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4927 * src/pic16/peeph.def: all peepholes with movff are commented out,
4928 because there is a problem in the pcode peep optimizer,
4929 * src/pic16/ralloc.c: the register allocator can now reuse local
4930 function symbols for another function. This saves register usage.

5022 include information about variables allocated to the overlay
5025 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5027 * as/mcs51/lkmain.c: Help about -Y option

5039 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5041 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5042 (default behaviour).
5044 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5046 A python script to validate compiler diagnostic messages. It can be
5047 used to verify that sdcc complains about bad c source code and
5048 gives a good location of the error.
5049 * support/valdiag/Makefile,
5050 * support/valdiag/valdiag.py,
5051 * support/valdiag/tests/*
5053 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5066 * src/common.h: added ifndef/define/endif macros
5067 around the header file.
5068 Bug reported from Jesus Calvino-Fraga
5070 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5072 * sdcc.spec: updated
5073 * device/include/Makefile.in: don't install CVS directories
5074 * device/lib/Makefile.in: added removal of CVS directories after install
5075 * doc/Makefile: fixed install, added local_icons
5076 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5077 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5078 * src/ds390/gen.c (genRightShift): fixed bug #870788
5079 * src/SDCCast.c (decorateType): fixed bug #870781
5081 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5083 PIC16 port related changes:
5084 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5085 added variable stackPos,
5087 * gen.c: genCall, assignResultValue: added support for
5088 pushing/retrieving function parameters to/from stack,
5089 genFunction,genEndFunction: setup stack frame for the
5091 genAddrOf: will be changed according to bug 863624
5093 * added files genutils.c and genutils.h which contain gen*
5094 debugged and optimised functions extracted from gen.c
5096 * glue.c: added variable 'externs' which holds extern symbols,
5097 pic16emitRegularMap: is modified to properly handle relocatable
5098 symbols under the new scheme,
5099 pic16createInterruptVect: is modified
5100 pic16printPublics: is modified to emit 'global' assembler directives,
5101 added pic16_printExterns to print extern symbols,
5102 pic16glue: initializes stack/frame pointer in the beginning of
5103 the assembly output. Temporary hack, will be corrected later,
5104 because gplink yet does not support stack and SDCC does not
5105 yet support a type of crt0.o object to create the final binary.
5107 * Removed many lines that contain 8051 legacy code.
5108 * The code is finally placed under a 'code' directive.
5109 * Added port specific options.
5111 * _process_pragma: simplified since now we do not need *special*
5112 include file to define SFR registers. But a separate header
5113 will be needed. This will be developed later.
5114 * _pic16_parseOptions: added, parses port specific options:
5115 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5116 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5117 --preplace-udata-with=
5119 * _pic16_setDefaultOptions: modified to initialize section names,
5120 but hack is temporarly out of order since it needs improvement.
5121 * _pic16_genAssemblerPreamble: configuration words are emitted by
5122 their address instead of their name. This part is incomplete and
5123 supports only the 18Fxx2 devices. Other devices will emit an error
5124 during assembly since they do not contain the same set of config
5126 * _pic16_genIVT: is modified,
5128 * pcode.c: added definitions for some hardware registers that are needed
5130 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5131 All PCI entries are updated. Now LFSR is supported.
5132 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5133 * added pic16_newpCodeOpLit2 to support instructions with
5134 two literal arguments
5135 * pic16_pCode2str: corrected code that emits assembler instructions
5136 with two literal operands and those that have an access bit modifier
5137 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5138 this fixes a bug which caused some labels to be lost, when an
5139 assembler directive was added, i.e. banksel,
5140 * pic16_FixRegisterBanking: improved logic that causes the insertion
5142 * InlineFunction: functions that are called once, are not any more
5143 inlined. This can be a port option in the future,
5145 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5147 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5148 hold the corresponding uninitialized symbols,
5149 * pic16_allocProcessorRegister: registers have explicit marked the
5151 * pic16_allocInternalRegister: registers are explicit marked as
5153 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5154 processing list, so bit registers were lost,
5157 * ralloc.h: added field 'accessBank' and original symbol operand
5158 in register definition,
5159 * removed the field isMapped from register definition,
5161 ** Several functions have been removed from various sources:
5162 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5163 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5164 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5165 pic16_assignRelocatableRegisters
5167 ** others have been introduced:
5168 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5169 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5171 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5173 * support/scripts/inc2h.pl: changed definition of BIT_AT
5174 to emit 'sbit at' instead of 'bit at'. This was a request.
5176 PIC16 port related preliminary changes:
5177 * gen.c: prefixed function popRegFromString with
5178 pic16_ and all references to it corrected
5179 * pcode.c: all pic16_pc_* hardware registers prefixed
5180 with underscore (_),
5181 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5182 * ralloc.c: newReg(): when register is REG_SFR then
5183 set address to rIdx,
5184 pic16_allocProcessorRegister(): marks register wasUsed=0
5185 pic16_writeUsedRegs(): added a call to assign processor
5186 registers via pic16_assignFixedRegisters
5188 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5190 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5191 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5192 variables in unused register banks. Also the SSEG is placed
5193 wherever there is enough space for it, and IDATA can be anywhere
5194 in internal RAM. For now compile using -Wl-Y[stack_size].
5195 The mem file is different for this option as well, since it
5196 makes no sense of talking about DSEG lenght.
5198 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5200 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5201 in certain cases, e.g. when ROM assignment, patch provided
5202 from Albert den Haan.
5204 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6227 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6228 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6229 type for bits was changed. It resulted in bit variables becoming

6247 A few small changes that speed up the peephole optimizer.
6251 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6253 Try to make the peephole optimizer smarter by maintaining
6254 an association between the assembly source code and the
6255 iCodes that originated them. Put this information to use
6256 with a new peephole rule condition "notVolatile" so that
6257 the rules can be aggressive yet still safe.
6262 * src/mcs51/peeph.def
6264 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6268 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6269 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6270 if the left or right operand symbols have the accuse flag set.
6272 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6274 Changed the type of the result of the ! (NOT) operator to char;
6275 previously it returned the same type as the source. This allows
6276 us to eliminate all the genFloatNot functions (all of its target
6277 implementations were very buggy) since !float can use the same
6280 * src/SDCCicode.c (ast2iCode): ! returns char

6289 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6290 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6291 during interrupts. Ensure WSAVE is located at a shared bank address.
6292 2. Fixed page selection in some places
6293 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6294 the registers name strings.
6295 4. Fixed "signed / unsigned compare" compiler warnings.
6296 5. The PIC port manages its own allocation of the general purpose
6297 registers, but makes no attempt to reuse them. As a result when
6298 compiling it soon runs out of general purpose registers. Some
6299 additional code was added to the files pcode.c and device.c to walk
6300 through the function call tree and rename the registers so that they
6310 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6317 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6319 Made bitfield a distinct type from bit so that bitfields
6320 convert as per ANSI C and bits retain their traditional
6321 boolean style behaviour. Implemented bitfield support in
6329 * src/ds390/gen.c: bit v bitfield split
6330 * src/z80/gen.c: New support for bitfields
6331 * support/regression/tests/bitfields.c: reenabled z80,
6334 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6336 Rules 246.x, 247.x relate to bitfields, the others speed up
6337 access to xdata mapped I/O devices.
6339 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6341 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6343 Cleaned up genPackBits and genUnpackBits and added two helper

6353 Fixed bug #748310 (pointer to function type mishandled when the
6354 function name is omitted). Also fixed a SIGSEGV when a function
6355 attribute (reentrant, etc) is used on a non-function or on a
6356 function but misplaced before the parameter list.

6385 Made the constant following the "interrupt" keyword optional. If
6386 omitted, the function will not automatically be given an entry
6387 in the interrupt vector table (similar to #pragma NOIV, but
6388 less syntacticly kludgy). The interrupt number is also now
6389 range checked. Also fixed a bug in the high order bit example
6396 * support/Util/SDCCerr.c
6397 * support/Util/SDCCerr.h
6400 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6410 unsigned, but are signed by default
6411 * src/SDCCval.c (constVal): rearranged
6412 * src/SDCCval.c (valMod): preliminary fix
6413 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6456 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6457 * src/SDCCval.c (valDiv, valMod): fixed signdness
6458 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6459 signedness of modulo, left and right shift

6922 the compiler with no port specified on command line, a default
6923 port is selected with the new macro DEFAULT_PORT which is
6924 defined in port.h, in setDefaultOptions() linkOptions is removed
6925 from initialization assignment, since now it is a set,
6926 parseCmdLine uses setParseWithComma for linkOptions, in
6927 linkEdit() linkOptions are accessed with new function indexSet()
6928 which returns the i'th item of a set variable. See SDCCset.c, in

7993 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7995 2003-01-04 <johan AT balder>
7997 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7999 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8000 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8002 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8003 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8010 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8012 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8013 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8015 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8017 * in \sdcc\as\mcs51\ changed these files in order to create an
8018 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8019 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8020 following files to include the previous two files: aslink.dsp,
8021 Makefile.aslink, Makefile.bcc, and Makefile.in.
8023 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8024 .adb instead of .cdb
8026 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8028 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8029 value from option --iram-size.
8031 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8033 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8036 2002-09-18 <wiml AT hhhh.org>
8038 * SDCClrange.h: exposed setFromRange() and setToRange()
8039 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8040 packRegsForAccUse() (bug 542397)
8041 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8042 multiple times and emitting the fetch operations more than once
8043 added aopGetUsesAcc() function to allow binary operators to
8044 fetch their operands in the correct order; made genMinus() emit
8045 compact code for X = LITERAL - Y
8047 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8048 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8049 sprintf() in line 1267.
8051 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8052 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8055 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8056 Changes to aslink (All the changes are marked with 'JCF'):
8058 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8061 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8062 area BSEG. Also moves, if possible, the DATA area down into the internal
8063 ram so more space is available.
8065 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8068 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8069 not bytes. Function summary() which creates a memory usage summary
8070 file with extension .mem. Reports of overlaping stack and small stack
8071 size. If the space for the stack is less than 16 bytes aslink trows a
8074 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8075 the 8051. Option 'y' for memory summary output file.
8077 Changes to sdcc (All the changes are marked with 'JCF'):
8079 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8081 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8082 overlaying area for it (uses RegBankUsed[4]).
8084 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8085 bank zero as used by default. By default aslink locates the stack
8086 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8087 the creation of the .mem file. Delegates the allocation of data area
8088 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8089 the begining of the stack area to aslink.
8091 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8092 glue() in SDCCglue.c creates an area for it.
8094 2002-09-03 Borut Razem <borut.razem AT siol.net>
8095 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8096 sdcc/src/pic/glue.c:
8097 introduced atexit() handler for teporay files removal in case of
8098 errors, assertions, ...
8100 2002-08-29 Borut Razem <borut.razem AT siol.net>
8101 * sdcc/support/cpp2/auto-host_vc_in.h:
8102 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8103 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8104 Maybe there is a similar problem with BORLANDC? It should be checked!
8106 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8107 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8108 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8109 was not executed, and the compiler (cl) launched a warning:
8110 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8112 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8113 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8115 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8116 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8118 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8119 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8120 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8121 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8122 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8123 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8124 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8125 - added Release configuration in VS projects
8126 - review of compiler an linker options
8127 - VC .exe files are generated in bin_vc directory, not to interfere
8128 with binaries generated from other projects (cygwin, mingw, bcc ...)
8130 * sdcc/src/yacc.dsp: added
8132 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8133 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8134 and insert the version number definitions from .version
8136 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8138 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8139 added - genarate auto-host.h using auto-host_vc_in.h as template
8142 removed from CVS, generated automatically
8144 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8145 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8147 2002-08-11 Borut Razem <borut.razem AT siol.net>
8148 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8150 2002-08-10 Borut Razem <borut.razem AT siol.net>
8151 * src/SDCCmain.c (main):
8152 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8153 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8154 The consequence was that some temporary files were not removed.
8157 unification of code in functions tempfilename() and tempfile():
8158 function tempnam() is defined in Visual Studio 6.0 and .NET
8160 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8162 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8163 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8164 - removed compiler command line option /WX: Treats all warnings as errors
8165 - update a list of source files, included into the project
8167 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8168 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8169 changed project type to Generic Project so that can be correcly converted to VS.NET project
8171 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8173 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8175 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8177 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8178 added return 0 statements after assert() to make compiler happy
8180 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8181 added newline in the def file to keep MSC compiler satisfied
8183 * sdcc/src/z80/gen.c:
8184 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8185 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8186 - solved MSC error in function aopDump()
8188 * sdcc_vc.h: define PREFIX as "\\sdcc"
8190 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8191 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8193 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8194 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8195 - Rewrote the register banking algorithm.
8196 - Added pCode live-range analysis to registers (for now, only non-used and
8197 singly-used registers optimized away)
8199 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8201 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
8203 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8204 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

8222 * src/z80/peeph.def: Added transpose redundent load rule.
8224 * src/z80/main.c: Added force callee saves for jaune.
8226 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8228 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8230 2002-03-28 Johan Knol <johan AT balder>
8232 * src/SDCCval.c: fixed bug #532436
8234 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8236 Added "char *Processor" field to the port structure.
8239 Added -p option. Allows port dependent processor to be specified.
8242 Initialized the new field char *Processor field to NULL in all ports
8245 Compiler generated registers for interrupt context saving
8246 were not getting allocated.
8248 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8251 Fixed left shift. Will promote the left side of a left shift
8252 if a) left shifting more than size of operand or b) when assigned
8253 to something size > size of left side
8255 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8257 tons of changes. Register allocation has been
8258 rewritten. Added customization for the various PICs. Flow
8259 analysis is restructured. ...
8265 Added. device.c is a PIC port hack to accomodate variations
8268 2002-03-13 Michael Hope <michaelh AT vroom>
8270 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8272 2002-03-04 johanknol <johanknol AT manik>
8274 * /src/SDCCval.c: fixed
8276 const unsigned char arr[][2] = { { 0, 1 } };
8277 t18.c:1: error: Initializer element is not constant
8279 2002-03-04 bela <bela AT manik>
8281 * /device/include/mcs51reg.h:
