898 but as registers instead (AOP_REG) using the fReturnIdx array,
899 * (pic16_freeAsmop): remove the freed register from the
901 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
903 * (pic16_popGetTempRegCond): changed function prototype, now
904 function takes also a bitVector argument v which holds the current
905 set of registers that are allocated for stack access by aopForSym,
906 registers allocated in aopForSym for accessing stack symbols are not
907 any more part of the functions usedRegs field,
908 * (genCall): some times aopOp is called for a stack variable to be
909 send, aopForSym might perform the push, if this is true make sure
910 that genCall doesn't push the variable twice by testing _G.resDirect,
911 * (genFunction): changed testing for unspecified interrupt number
912 from 256 to INTNO_UNSPEC,
913 * modified selection scheme of frame pointer generation. Previously
914 if function did use local registers a frame pointer was generated,
915 now a frame pointer is generated only if function has arguments
916 (that need PLUSW2 register access), or has stack arguments, or the
917 compiler is not instructed to omit the frame pointer,
918 * (genEndFunction): before restoring local registers that were saved
919 in the function preamble, also restore the registers that *might*
920 have been allocated for stack access,
921 * (genRet): removed some old comments,
922 * (genCmp, the active (RN's) version): added a call to the
923 pic16_genCmp_special function to perform the compare with a more
924 robust and optimized way,
925 * (genInline): a feature has been added in inline code generation,
926 which allows a wildcard variable substitution when writing inline
927 assembly. Code is incomplete and experimental therefore undocumented,
928 * (genCast): changed order of aopOp for result and right to allow
929 aopForSym to directly load the result if possible,
930 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
931 perform an optimized compare on some selected special occasions,
932 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
933 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
934 generate an IVT any more,
935 * src/pic16/main.c (pic16_optionsTable): added command line option
937 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
938 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
940 * src/pic16/NOTES: Raphael Neider added in list of active developers
941 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
942 jumptable_end to prevent bug #,
943 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
944 inCond and outCond fields,
945 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
946 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
947 turn off register spilling,
948 * (packRegsForOneUse): synced with other ports' versions although it
949 is not used currently,
950 * (pic16_packRegisters): added an optimization while reading
951 structure bitfields, some registers may be saved (malloc code is
952 decreased by 80 bytes)
954 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
956 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
957 left is a bitfield, if yes, then don't optimize assignment. Perhaps
958 this can be optimized more?
960 2005-03-10 Raphael Neider <rneider AT web.de>
962 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
963 genNearPointerGet): (hopefully) fixed access to bitfields via
964 pointers (p->bitN = x; and x = p->bitN; failed)

1157 (volatile operands might get thrown away though)
1159 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1290 access stack and frame pointers. They are initially assigned to
1291 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1292 accessing SFRs. Updated all occurences of modification of stack or
1293 frame pointer in gen.c and pcode.c,
1294 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
1295 assigning of a literal value to pointers,

1323 to hold the condition bit)
1324 * added new version of genCmp (old code available via #define)
1325 * added new version of genShiftLeft/genShiftRight in a generic

1338 from Raphael Neider,
1339 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
1340 for 8-bit literals. This fixes some literal operands which are sign
1341 extended to 16-bits ints when instruction needs only 8-bits.

1599 generated for switch statements. For now you need to set the
1600 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1601 Now 4 algorithms for mcs51 jumptable generation are used:
1602 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1636 * added libc directory. The current version of LibC contains string
1637 functions, ctype functions and macros and some functions of the
1638 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1639 be extensively tested in the future. Standard disclaimer here.

1653 * (genCmp): experimental code for new genCmp which uses PIC18's
1654 special compare&skip instructions. Initial tests fail some times
1655 with variables grater than 1 byte in size, so new code is disabled,
1656 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1658 * (genCast): began a fix to optimize the casting of a bit to another
1659 bit, now assigning a bitfield to another bitfield will fail, sorry,

1673 registers when it shouldn't,
1674 * src/pic16/ralloc.c (allocReg): add preliminary support for
1675 supporting a limited set of temporary registers,
1677 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4684 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4685 loaded with the linker search paths (-L arguments) and the libraries
4686 to be linked with the current source (-l arguments). Changes
4687 currently will affect only the pic16 port.
4688 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4689 include path the port specific paths and port specific libraries,
4690 * gplink command now contains the $3 argument,
4691 * src/pic16/device.h,
4692 * src/pic16/device.c,: structure PIC_device is made public and
4693 renamed to PIC16_device, the same for variable Pics which is renamed

4708 Documenting changes from previous commits.
4709 * configure.in (version 1.56),
4710 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4711 when generating output files to configure the pic16 library,
4712 but now I've commented it out, since gputils aren't installed in the
4713 SF compile farm, so library won't compile
4715 * device/lib/Makefile.in (version 1.56): initially I've added in
4716 target 'all' the prerequestive 'model-pic16' so it compiled the
4717 pic16 library, but now I've commented it out for the same reasons
4719 * added targets 'model-pic16' and 'objects-pic16' to compile the
4721 * added target 'port-specific-objects-pic16' to handle the
4722 generated libraries and copy them into the build/ directory
4723 * added target 'clean-intermediate-pic16' to clean intermediate
4724 files into pic16 directory
4725 * in target 'installdirs' added line to create directory pic16 in

4747 option so that it actually works. Made it specific to the z80, since
4748 the gbz80 doesn't have these kinds of I/O ports.
4750 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4776 via literal number. The symbol is placed in the corresponding
4777 position of the data ram
4778 * (pic16_dump_section): relocatable and absolute uninitialized
4779 data are now emitted in sorted order to reduce section naming,
4780 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4781 weren't marked as being in the access bank,

4974 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4976 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4977 (default behaviour).
4979 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4981 A python script to validate compiler diagnostic messages. It can be
4982 used to verify that sdcc complains about bad c source code and
4983 gives a good location of the error.
4984 * support/valdiag/Makefile,
4985 * support/valdiag/valdiag.py,

5005 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5007 * sdcc.spec: updated
5008 * device/include/Makefile.in: don't install CVS directories

5010 * doc/Makefile: fixed install, added local_icons
5011 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5012 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5013 * src/ds390/gen.c (genRightShift): fixed bug #870788

5016 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5018 PIC16 port related changes:
5019 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5020 added variable stackPos,
5022 * gen.c: genCall, assignResultValue: added support for
5023 pushing/retrieving function parameters to/from stack,
5024 genFunction,genEndFunction: setup stack frame for the
5026 genAddrOf: will be changed according to bug 863624
5028 * added files genutils.c and genutils.h which contain gen*
5029 debugged and optimised functions extracted from gen.c
5031 * glue.c: added variable 'externs' which holds extern symbols,
5032 pic16emitRegularMap: is modified to properly handle relocatable
5033 symbols under the new scheme,
5034 pic16createInterruptVect: is modified
5035 pic16printPublics: is modified to emit 'global' assembler directives,
5036 added pic16_printExterns to print extern symbols,
5037 pic16glue: initializes stack/frame pointer in the beginning of
5038 the assembly output. Temporary hack, will be corrected later,
5039 because gplink yet does not support stack and SDCC does not
5040 yet support a type of crt0.o object to create the final binary.
5042 * Removed many lines that contain 8051 legacy code.
5043 * The code is finally placed under a 'code' directive.
5044 * Added port specific options.
5046 * _process_pragma: simplified since now we do not need *special*
5047 include file to define SFR registers. But a separate header
5048 will be needed. This will be developed later.
5049 * _pic16_parseOptions: added, parses port specific options:
5050 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5051 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5052 --preplace-udata-with=
5054 * _pic16_setDefaultOptions: modified to initialize section names,
5055 but hack is temporarly out of order since it needs improvement.
5056 * _pic16_genAssemblerPreamble: configuration words are emitted by
5057 their address instead of their name. This part is incomplete and
5058 supports only the 18Fxx2 devices. Other devices will emit an error
5059 during assembly since they do not contain the same set of config
5061 * _pic16_genIVT: is modified,
5063 * pcode.c: added definitions for some hardware registers that are needed
5065 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5066 All PCI entries are updated. Now LFSR is supported.
5067 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5068 * added pic16_newpCodeOpLit2 to support instructions with
5069 two literal arguments
5070 * pic16_pCode2str: corrected code that emits assembler instructions
5071 with two literal operands and those that have an access bit modifier
5072 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5073 this fixes a bug which caused some labels to be lost, when an
5074 assembler directive was added, i.e. banksel,
5075 * pic16_FixRegisterBanking: improved logic that causes the insertion
5077 * InlineFunction: functions that are called once, are not any more
5078 inlined. This can be a port option in the future,
5080 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5082 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5083 hold the corresponding uninitialized symbols,
5084 * pic16_allocProcessorRegister: registers have explicit marked the
5086 * pic16_allocInternalRegister: registers are explicit marked as
5088 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5089 processing list, so bit registers were lost,
5092 * ralloc.h: added field 'accessBank' and original symbol operand
5093 in register definition,
5094 * removed the field isMapped from register definition,
5096 ** Several functions have been removed from various sources:
5097 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5098 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5099 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5100 pic16_assignRelocatableRegisters
5102 ** others have been introduced:
5103 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5104 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5106 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5108 * support/scripts/inc2h.pl: changed definition of BIT_AT
5109 to emit 'sbit at' instead of 'bit at'. This was a request.
5111 PIC16 port related preliminary changes:
5112 * gen.c: prefixed function popRegFromString with
5113 pic16_ and all references to it corrected
5114 * pcode.c: all pic16_pc_* hardware registers prefixed
5115 with underscore (_),
5116 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5117 * ralloc.c: newReg(): when register is REG_SFR then
5118 set address to rIdx,
5119 pic16_allocProcessorRegister(): marks register wasUsed=0
5120 pic16_writeUsedRegs(): added a call to assign processor
5121 registers via pic16_assignFixedRegisters
5123 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5125 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5126 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5127 variables in unused register banks. Also the SSEG is placed
5128 wherever there is enough space for it, and IDATA can be anywhere
5129 in internal RAM. For now compile using -Wl-Y[stack_size].
5130 The mem file is different for this option as well, since it
5131 makes no sense of talking about DSEG lenght.
5133 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5135 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5136 in certain cases, e.g. when ROM assignment, patch provided
5137 from Albert den Haan.

6045 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6047 Fixed bug #621531 (const & volatile confusion in the type chain).
6048 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6142 fetching of the pointer
6143 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6144 copied from genNearPointerSet()
6145 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6146 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6147 If they pop r0/r1 they must be called in the opposite order than aopOp().
6148 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6149 (resp. --stack-auto), prepared for --xstack

6160 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6162 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6163 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6164 type for bits was changed. It resulted in bit variables becoming
6165 global, which is not permitted in PIC 14 assembly output.
6167 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6169 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6182 A few small changes that speed up the peephole optimizer.
6186 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6188 Try to make the peephole optimizer smarter by maintaining
6189 an association between the assembly source code and the
6190 iCodes that originated them. Put this information to use
6191 with a new peephole rule condition "notVolatile" so that
6192 the rules can be aggressive yet still safe.
6197 * src/mcs51/peeph.def
6199 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6203 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6204 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6205 if the left or right operand symbols have the accuse flag set.
6207 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6209 Changed the type of the result of the ! (NOT) operator to char;
6210 previously it returned the same type as the source. This allows
6211 us to eliminate all the genFloatNot functions (all of its target
6212 implementations were very buggy) since !float can use the same
6215 * src/SDCCicode.c (ast2iCode): ! returns char
6216 * src/mcs51/gen.c (genNot, genNotFloat),
6217 * src/ds390/gen.c (genNot, genNotFloat),
6218 * src/z80/gen.c (genNot, genNotFloat),
6219 * src/pic/gen.c (genNot, genNotFloat),
6220 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6222 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6224 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6225 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6226 during interrupts. Ensure WSAVE is located at a shared bank address.
6227 2. Fixed page selection in some places
6228 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6229 the registers name strings.
6230 4. Fixed "signed / unsigned compare" compiler warnings.
6231 5. The PIC port manages its own allocation of the general purpose
6232 registers, but makes no attempt to reuse them. As a result when
6233 compiling it soon runs out of general purpose registers. Some
6234 additional code was added to the files pcode.c and device.c to walk
6235 through the function call tree and rename the registers so that they
6245 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6246 genPlus() & genMinus() when the result is the same as left or right
6248 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6252 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6254 Made bitfield a distinct type from bit so that bitfields
6255 convert as per ANSI C and bits retain their traditional
6256 boolean style behaviour. Implemented bitfield support in
6264 * src/ds390/gen.c: bit v bitfield split
6265 * src/z80/gen.c: New support for bitfields
6266 * support/regression/tests/bitfields.c: reenabled z80,
6269 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6271 Rules 246.x, 247.x relate to bitfields, the others speed up
6272 access to xdata mapped I/O devices.
6274 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6276 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6278 Cleaned up genPackBits and genUnpackBits and added two helper
6279 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6280 for literal assignments in genPackBits (thanks to Frieder for
6286 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6288 Fixed bug #748310 (pointer to function type mishandled when the
6289 function name is omitted). Also fixed a SIGSEGV when a function
6290 attribute (reentrant, etc) is used on a non-function or on a
6291 function but misplaced before the parameter list.
6293 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6295 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6296 * support/Util/SDCCerr.h,
6297 * support/Util/SDCCerr.c: Added func attr misuse error msg
6299 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6301 Fixed bug #787649 by anonymous
6302 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6318 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6320 Made the constant following the "interrupt" keyword optional. If
6321 omitted, the function will not automatically be given an entry
6322 in the interrupt vector table (similar to #pragma NOIV, but
6323 less syntacticly kludgy). The interrupt number is also now
6324 range checked. Also fixed a bug in the high order bit example

6338 * src/SDCCicode.c (operandOperation): rewritten some ops
6339 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6340 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6342 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6343 be re-activated by defining REDUCE_LITERALS)
6344 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6345 unsigned, but are signed by default
6346 * src/SDCCval.c (constVal): rearranged
6347 * src/SDCCval.c (valMod): preliminary fix
6348 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6390 constants are unsigned; added recognition of "u" flag for unsigned
6391 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6392 * src/SDCCval.c (valDiv, valMod): fixed signdness
6393 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6394 signedness of modulo, left and right shift

6854 added if/endif conditional macros to remove options help
6855 messages from optionsTable when a port is not configured, added
6856 support for the PIc16 port in the ports table, when executing
6857 the compiler with no port specified on command line, a default
6858 port is selected with the new macro DEFAULT_PORT which is
6859 defined in port.h, in setDefaultOptions() linkOptions is removed
6860 from initialization assignment, since now it is a set,
6861 parseCmdLine uses setParseWithComma for linkOptions, in
6862 linkEdit() linkOptions are accessed with new function indexSet()
6863 which returns the i'th item of a set variable. See SDCCset.c, in
6864 linkEdit() when calling buildCmdLine(), added linkOptions as
6865 last argument. Now users can pass arguments to gplink via the
6866 -Wl option, main() uses pic16glue() to glue up pic16 programs

6880 gpasm complaining and test the linkage with gplink, _linkCmd and
6881 _asmCmd changed to be more gplink and gpasm friendly
6882 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6883 produced an error when parsed, peep rule 12 is added to utilize
6884 movff, but it is commented out since the pCode does not support
6885 yet a command with 2 address arguments
6887 2003-05-18 <johan AT balder>
6889 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6912 2003-05-12 Borut Razem <borut.razem AT siol.net>
6914 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6916 2003-05-11 Borut Razem <borut.razem AT siol.net>
6918 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6919 the path of bin directory, so that PATH is the only env. variable, which has to be set
6920 in case of standard installation.

7930 2003-01-04 <johan AT balder>
7932 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7934 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7950 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7952 * in \sdcc\as\mcs51\ changed these files in order to create an
7953 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7954 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7955 following files to include the previous two files: aslink.dsp,
7956 Makefile.aslink, Makefile.bcc, and Makefile.in.
7958 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7959 .adb instead of .cdb
7961 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7963 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7964 value from option --iram-size.
7966 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7968 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7971 2002-09-18 <wiml AT hhhh.org>
7973 * SDCClrange.h: exposed setFromRange() and setToRange()
7974 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7975 packRegsForAccUse() (bug 542397)
7976 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7977 multiple times and emitting the fetch operations more than once
7978 added aopGetUsesAcc() function to allow binary operators to
7979 fetch their operands in the correct order; made genMinus() emit
7980 compact code for X = LITERAL - Y
7982 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7983 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7984 sprintf() in line 1267.
7986 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7987 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7990 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7991 Changes to aslink (All the changes are marked with 'JCF'):
7993 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7996 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7997 area BSEG. Also moves, if possible, the DATA area down into the internal
7998 ram so more space is available.
8000 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8003 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8004 not bytes. Function summary() which creates a memory usage summary
8005 file with extension .mem. Reports of overlaping stack and small stack
8006 size. If the space for the stack is less than 16 bytes aslink trows a
8009 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8010 the 8051. Option 'y' for memory summary output file.
8012 Changes to sdcc (All the changes are marked with 'JCF'):
8014 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8016 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8017 overlaying area for it (uses RegBankUsed[4]).
8019 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8020 bank zero as used by default. By default aslink locates the stack
8021 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8022 the creation of the .mem file. Delegates the allocation of data area
8023 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8024 the begining of the stack area to aslink.
8026 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8027 glue() in SDCCglue.c creates an area for it.
8029 2002-09-03 Borut Razem <borut.razem AT siol.net>
8030 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8031 sdcc/src/pic/glue.c:
8032 introduced atexit() handler for teporay files removal in case of
8033 errors, assertions, ...
8035 2002-08-29 Borut Razem <borut.razem AT siol.net>
8036 * sdcc/support/cpp2/auto-host_vc_in.h:
8037 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8038 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8039 Maybe there is a similar problem with BORLANDC? It should be checked!
8041 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8042 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8043 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8044 was not executed, and the compiler (cl) launched a warning:
8045 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8047 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8048 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8050 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8051 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8053 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8054 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8055 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8056 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8057 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8058 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8059 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8060 - added Release configuration in VS projects
8061 - review of compiler an linker options
8062 - VC .exe files are generated in bin_vc directory, not to interfere
8063 with binaries generated from other projects (cygwin, mingw, bcc ...)
8065 * sdcc/src/yacc.dsp: added
8067 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8068 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8069 and insert the version number definitions from .version
8071 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8073 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8074 added - genarate auto-host.h using auto-host_vc_in.h as template
8077 removed from CVS, generated automatically
8079 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8080 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8082 2002-08-11 Borut Razem <borut.razem AT siol.net>
8083 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8085 2002-08-10 Borut Razem <borut.razem AT siol.net>
8086 * src/SDCCmain.c (main):
8087 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8088 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8089 The consequence was that some temporary files were not removed.
8092 unification of code in functions tempfilename() and tempfile():
8093 function tempnam() is defined in Visual Studio 6.0 and .NET
8095 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8097 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8098 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8099 - removed compiler command line option /WX: Treats all warnings as errors
8100 - update a list of source files, included into the project
8102 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8103 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8104 changed project type to Generic Project so that can be correcly converted to VS.NET project
8106 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8108 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8110 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8112 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8113 added return 0 statements after assert() to make compiler happy
8115 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8116 added newline in the def file to keep MSC compiler satisfied
8118 * sdcc/src/z80/gen.c:
8119 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8120 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8121 - solved MSC error in function aopDump()
8123 * sdcc_vc.h: define PREFIX as "\\sdcc"
8125 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8126 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8169 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8171 Added "char *Processor" field to the port structure.
8174 Added -p option. Allows port dependent processor to be specified.
8177 Initialized the new field char *Processor field to NULL in all ports
8180 Compiler generated registers for interrupt context saving
8181 were not getting allocated.
8183 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8186 Fixed left shift. Will promote the left side of a left shift
8187 if a) left shifting more than size of operand or b) when assigned
8188 to something size > size of left side
8190 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8192 tons of changes. Register allocation has been
8193 rewritten. Added customization for the various PICs. Flow
8194 analysis is restructured. ...
8200 Added. device.c is a PIC port hack to accomodate variations
8203 2002-03-13 Michael Hope <michaelh AT vroom>
8205 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

8302 not really partof a loop , but live ranges used in these blocks should
8303 be live thru the entire loop, so set partOfLoop but don't add them to
