3475 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3476 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3478 One basic decision: e.g. src/clean.mk includes further files. In order
3479 to make this work there are two solutions:
3480 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3481 run configure on them. This way they can use
3482 'include $(srcdir)/port-clean.mk'
3483 - always include clean.mk by the Makefile at the same level. To avoid
3484 that `make clean` tries to include and build Makefile.dep the
3485 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3486 implemented, because now even `make uninstall` doesn't create
3487 Makefile.in. clean.mk could be eliminated by pasting it in
3490 * debugger/mcs51/Makefile.in: build own objects from library sources

3756 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3758 * src/mcs51/gen.c (genCall): fixed bug 1457608
3760 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3778 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3779 implemented patch 1120823 Thanks to Willy De la Court (normal
3780 interrupts need an interrupt number now if they are made critical),
3781 and enabled nesting of critical functions though not for gbz80
3782 (genCritical, genEndCritical): added functions
3783 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3784 * src/z80/mappings.i: added "ei" to all mappings

3793 2006-03-16 Raphael Neider <rneider AT web.de>
3795 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3796 the left operand is shorter than the result (c* = lit-c* + int),
3798 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3801 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3803 * src/.version: increased version number to 2.5.5
3804 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3805 linking is done manually in pic16 port's _linkEdit,
3806 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3807 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3808 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3809 allocate asmop as AOP_ACC,
3810 (aopForRemat): added parameter 'bool result' in function declaration,
3811 (pic16_aopGet): return AOP_ACC when accessing WREG,
3812 (pic16_popGetTempReg): minor modification,

3823 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3824 call to allocReg, not by manually allocating a new one,
3825 (pic16_assignRegisters): now before going through the register
3826 allocating functions mark all registers as free. This eliminates some
3827 side effects resulting from peephole parser done earlier in the backbone
3829 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3831 * src/SDCCicode.c (geniCodeLogic),

3877 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3879 2006-03-06 Borut Razem <borut.razem AT siol.net>
3881 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3882 made the linker quiet
3884 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3886 * src/pic16/gen.c (genPcall): fixed bug #1443644
3887 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3888 which dumps before the function entry point a data byte which represents
3889 the number of the local variables used by the specified function, added
3890 'xinst' for initial support for Extended Instruction Support,
3891 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3892 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3893 port->fun_prefix anymore (may change later),
3894 (genFunction, genEndFunction): do not store/restore local registers for
3895 _main (this should take care the --main-return command line option in
3897 (genOr): removed some legacy pic-port instructions,
3898 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3899 performing operations with SFR's causes data to be written more than
3900 once to each SFR. Perhaps SFRs should be handled in special cases...
3901 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3903 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3904 into account for stack starting position,
3905 (struct OPTIONS pic16_optionsTable): added command line argument
3906 --extended or -y for Extended Instruction Support,
3907 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3908 (deassignLRs): *** perhaps the most important change, old 'for' code
3909 (commented out for reference), didn't account for some registers which
3910 were left marked 'not free' after a pointer operation. The change

6184 * src/SDCCglobal.h (struct options),
6186 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6187 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6188 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6189 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6190 always available in leading double underscore form. The C99 support is
6191 mostly missing, but it's a start.
6192 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6193 reserved identifier "__data".
6195 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

6271 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6273 * device/lib/printf_large.c: removed inline assembly for portability and
6274 readability. Use printf_fast if speed or size are more important.
6275 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6276 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6278 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6280 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6281 prevent compiler warning
6283 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6285 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6286 moved to level 0 and declared as static. Also they are explicit
6287 placed in access bank. This was necessery because some times they
6288 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6289 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6290 optimizations. Currently only compare to unsigned char is implemented,
6291 * src/pic16/gen.c: added fReturnIdx array,
6292 * (struct resolvedIfx) is moved to gen.h and made public,
6293 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6294 * (aopForSym): added an optimization to directly store in stack of
6295 the operand of a SEND iCode,
6296 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6297 but as registers instead (AOP_REG) using the fReturnIdx array,
6298 * (pic16_freeAsmop): remove the freed register from the
6299 _G.sregsAlloc field,
6300 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6301 a compare of 'WREG',
6302 * (pic16_popGetTempRegCond): changed function prototype, now
6303 function takes also a bitVector argument v which holds the current
6304 set of registers that are allocated for stack access by aopForSym,
6305 registers allocated in aopForSym for accessing stack symbols are not
6306 any more part of the functions usedRegs field,
6307 * (genCall): some times aopOp is called for a stack variable to be
6308 send, aopForSym might perform the push, if this is true make sure
6309 that genCall doesn't push the variable twice by testing _G.resDirect,
6310 * (genFunction): changed testing for unspecified interrupt number
6311 from 256 to INTNO_UNSPEC,
6312 * modified selection scheme of frame pointer generation. Previously
6313 if function did use local registers a frame pointer was generated,
6314 now a frame pointer is generated only if function has arguments
6315 (that need PLUSW2 register access), or has stack arguments, or the
6316 compiler is not instructed to omit the frame pointer,
6317 * (genEndFunction): before restoring local registers that were saved
6318 in the function preamble, also restore the registers that *might*
6319 have been allocated for stack access,
6320 * (genRet): removed some old comments,
6321 * (genCmp, the active (RN's) version): added a call to the
6322 pic16_genCmp_special function to perform the compare with a more
6323 robust and optimized way,
6324 * (genInline): a feature has been added in inline code generation,
6325 which allows a wildcard variable substitution when writing inline
6326 assembly. Code is incomplete and experimental therefore undocumented,
6327 * (genCast): changed order of aopOp for result and right to allow
6328 aopForSym to directly load the result if possible,
6329 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6330 perform an optimized compare on some selected special occasions,
6331 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6332 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6333 generate an IVT any more,
6334 * src/pic16/main.c (pic16_optionsTable): added command line option
6336 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6337 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6339 * src/pic16/NOTES: Raphael Neider added in list of active developers
6340 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6341 jumptable_end to prevent bug #,
6342 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6343 inCond and outCond fields,
6344 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6345 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6346 turn off register spilling,
6347 * (packRegsForOneUse): synced with other ports' versions although it
6348 is not used currently,
6349 * (pic16_packRegisters): added an optimization while reading
6350 structure bitfields, some registers may be saved (malloc code is
6351 decreased by 80 bytes)
6353 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6355 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6356 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6357 this can be optimized more?
6359 2005-03-10 Raphael Neider <rneider AT web.de>
6361 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6362 genNearPointerGet): (hopefully) fixed access to bitfields via
6363 pointers (p->bitN = x; and x = p->bitN; failed)

6408 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
6409 to keep the correct label reference count when adding/removing references
6410 to labels. A peephole file using this is appended to patch #1144962.
6412 2005-02-14 Raphael Neider <rneider AT web.de>

6997 Adding support for replacing ljmps with sjmps in jumptables
6998 generated for switch statements. For now you need to set the
6999 environment variable SDCC_SJMP_JUMPTABLE to enable this.
7000 Now 4 algorithms for mcs51 jumptable generation are used:
7001 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
7002 addresses loaded pc-relative for up to 112 cases and stack-pushing
7003 target addresses loaded with offset from dptr for up to 256 cases.

7033 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7035 * added libc directory. The current version of LibC contains string
7036 functions, ctype functions and macros and some functions of the
7037 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7038 be extensively tested in the future. Standard disclaimer here.
7039 Library is not automatically build yet. But one can build it by
7040 invoking 'make' inside the libc directory.

7051 * (pic16_storeForReturn): optimized return of 0,
7052 * (genCmp): experimental code for new genCmp which uses PIC18's
7053 special compare&skip instructions. Initial tests fail some times
7054 with variables grater than 1 byte in size, so new code is disabled,
7055 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7057 * (genCast): began a fix to optimize the casting of a bit to another
7058 bit, now assigning a bitfield to another bitfield will fail, sorry,

7072 registers when it shouldn't,
7073 * src/pic16/ralloc.c (allocReg): add preliminary support for
7074 supporting a limited set of temporary registers,
7076 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9972 * src/SDCCast.c (addCast): added promotion to int
9973 (decorateType): updated call to upCast()
9974 * src/SDCCicode.c (geniCodeLeftShift): removed call to
9975 usualUnaryConversions()
9977 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
9979 * support/regression/tests/literalop.c (mulWrapper): Added a
9980 wrapper to remove integer overflow warnings.
9982 * support/regression/tests/float_trans.c: Made work on host.

9991 missing directory install warning.
9993 * as/Makefile (install-doc): Made work on Mac.
9995 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
9997 * src/SDCCast.c: added an additional type flow in decorateType() of
9998 opposite direction, see feature request #860006; it's enabled at runtime
9999 by setting the environment variable SDCC_NEWTYPEFLOW
10000 * src/SDCCast.h: changed prototype of decorateType()
10001 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
10002 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
10003 'char' to 'int' can be omitted, if both operands are 'unsigned char';
10004 see feature request #877103
10005 * src/SDCCval.c: updated call of decorateType()
10006 (valBitwise): fixed bug #882876
10007 (valMinus): added promotion
10008 (valLogicAndOr): result is unsigned
10009 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
10010 * src/SDCCsymt.c (computeType),
10011 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
10012 must not cause an unsigned operation
10013 * src/pic/glue (pic14emitRegularMap),

10033 * src/pic/ralloc.h: applied patch from Slade Rich;
10034 added support for multiple code pages and multiple RAM banks on the
10035 PIC 14 port. The ASM files now no longer simply assume all the
10036 code / RAM are in the same page / bank. This means the linker can
10037 safely allocate code/RAM of separate ASM files to different pages/banks.
10038 * doc/sdccman.lyx: added Slade's tips
10039 * src/mcs51/peeph.def: fixed bug #880768

10081 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10083 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10084 loaded with the linker search paths (-L arguments) and the libraries
10085 to be linked with the current source (-l arguments). Changes
10086 currently will affect only the pic16 port.
10087 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10088 include path the port specific paths and port specific libraries,
10089 * gplink command now contains the $3 argument,
10090 * src/pic16/device.h,
10091 * src/pic16/device.c,: structure PIC_device is made public and
10092 renamed to PIC16_device, the same for variable Pics which is renamed

10105 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10107 Documenting changes from previous commits.
10108 * configure.in (version 1.56),
10109 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10110 when generating output files to configure the pic16 library,
10111 but now I've commented it out, since gputils aren't installed in the
10112 SF compile farm, so library won't compile
10114 * device/lib/Makefile.in (version 1.56): initially I've added in
10115 target 'all' the prerequestive 'model-pic16' so it compiled the
10116 pic16 library, but now I've commented it out for the same reasons
10118 * added targets 'model-pic16' and 'objects-pic16' to compile the
10120 * added target 'port-specific-objects-pic16' to handle the
10121 generated libraries and copy them into the build/ directory
10122 * added target 'clean-intermediate-pic16' to clean intermediate
10123 files into pic16 directory
10124 * in target 'installdirs' added line to create directory pic16 in
10125 the installation path
10127 * device/include/Makefile.in (version 1.11): in target 'install'
10128 added lines to copy all header files to installation path,
10129 * in target 'installdirs' added line create directory for pic16
10130 headers in the installation path

10143 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10145 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10146 option so that it actually works. Made it specific to the z80, since
10147 the gbz80 doesn't have these kinds of I/O ports.
10149 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10151 * device/include/z180.h,

10175 via literal number. The symbol is placed in the corresponding
10176 position of the data ram
10177 * (pic16_dump_section): relocatable and absolute uninitialized
10178 data are now emitted in sorted order to reduce section naming,
10179 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10180 weren't marked as being in the access bank,
10182 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10184 Added portion of GNU PIC Library under the directory
10185 device/include/pic16 and device/lib/pic16. These files
10186 contain the declarations of SFRs for the PIC18Fxx2 devices.
10187 The directory is initialized via configure from toplevel.
10189 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10191 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10192 the spilllocations to be compared correctly

10217 all over. Telling LaTeX to be less strict with word spacing
10218 to better keep the right margin. Changed some notes about
10219 maintainance of the ports in section 3.2.1 - is it OK like this?
10221 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

10380 A python script to validate compiler diagnostic messages. It can be
10381 used to verify that sdcc complains about bad c source code and
10382 gives a good location of the error.
10383 * support/valdiag/Makefile,
10384 * support/valdiag/valdiag.py,
10385 * support/valdiag/tests/*

10404 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10406 * sdcc.spec: updated
10407 * device/include/Makefile.in: don't install CVS directories

10410 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
10411 * src/mcs51/gen.c (genRightShift): fixed bug #870788
10412 * src/ds390/gen.c (genRightShift): fixed bug #870788
10413 * src/SDCCast.c (decorateType): fixed bug #870781
10415 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10417 PIC16 port related changes:
10418 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10419 added variable stackPos,
10421 * gen.c: genCall, assignResultValue: added support for
10422 pushing/retrieving function parameters to/from stack,
10423 genFunction,genEndFunction: setup stack frame for the
10424 generated function,
10425 genAddrOf: will be changed according to bug 863624
10427 * added files genutils.c and genutils.h which contain gen*
10428 debugged and optimised functions extracted from gen.c
10430 * glue.c: added variable 'externs' which holds extern symbols,
10431 pic16emitRegularMap: is modified to properly handle relocatable
10432 symbols under the new scheme,
10433 pic16createInterruptVect: is modified
10434 pic16printPublics: is modified to emit 'global' assembler directives,
10435 added pic16_printExterns to print extern symbols,
10436 pic16glue: initializes stack/frame pointer in the beginning of
10437 the assembly output. Temporary hack, will be corrected later,
10438 because gplink yet does not support stack and SDCC does not
10439 yet support a type of crt0.o object to create the final binary.
10441 * Removed many lines that contain 8051 legacy code.
10442 * The code is finally placed under a 'code' directive.
10443 * Added port specific options.
10445 * _process_pragma: simplified since now we do not need *special*
10446 include file to define SFR registers. But a separate header
10447 will be needed. This will be developed later.
10448 * _pic16_parseOptions: added, parses port specific options:
10449 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10450 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10451 --preplace-udata-with=
10453 * _pic16_setDefaultOptions: modified to initialize section names,
10454 but hack is temporarly out of order since it needs improvement.
10455 * _pic16_genAssemblerPreamble: configuration words are emitted by
10456 their address instead of their name. This part is incomplete and
10457 supports only the 18Fxx2 devices. Other devices will emit an error
10458 during assembly since they do not contain the same set of config
10460 * _pic16_genIVT: is modified,
10462 * pcode.c: added definitions for some hardware registers that are needed
10464 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10465 All PCI entries are updated. Now LFSR is supported.
10466 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10467 * added pic16_newpCodeOpLit2 to support instructions with
10468 two literal arguments
10469 * pic16_pCode2str: corrected code that emits assembler instructions
10470 with two literal operands and those that have an access bit modifier
10471 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10472 this fixes a bug which caused some labels to be lost, when an
10473 assembler directive was added, i.e. banksel,
10474 * pic16_FixRegisterBanking: improved logic that causes the insertion
10476 * InlineFunction: functions that are called once, are not any more
10477 inlined. This can be a port option in the future,
10479 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10481 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10482 hold the corresponding uninitialized symbols,
10483 * pic16_allocProcessorRegister: registers have explicit marked the
10485 * pic16_allocInternalRegister: registers are explicit marked as
10487 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10488 processing list, so bit registers were lost,
10491 * ralloc.h: added field 'accessBank' and original symbol operand
10492 in register definition,
10493 * removed the field isMapped from register definition,
10495 ** Several functions have been removed from various sources:
10496 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10497 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10498 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10499 pic16_assignRelocatableRegisters
10501 ** others have been introduced:
10502 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10503 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10505 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10507 * support/scripts/inc2h.pl: changed definition of BIT_AT
10508 to emit 'sbit at' instead of 'bit at'. This was a request.
10510 PIC16 port related preliminary changes:
10511 * gen.c: prefixed function popRegFromString with
10512 pic16_ and all references to it corrected
10513 * pcode.c: all pic16_pc_* hardware registers prefixed
10514 with underscore (_),
10515 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10516 * ralloc.c: newReg(): when register is REG_SFR then
10517 set address to rIdx,
10518 pic16_allocProcessorRegister(): marks register wasUsed=0
10519 pic16_writeUsedRegs(): added a call to assign processor
10520 registers via pic16_assignFixedRegisters
10522 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10524 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10525 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10526 variables in unused register banks. Also the SSEG is placed
10527 wherever there is enough space for it, and IDATA can be anywhere
10528 in internal RAM. For now compile using -Wl-Y[stack_size].
10529 The mem file is different for this option as well, since it
10530 makes no sense of talking about DSEG lenght.
10532 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10534 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10535 in certain cases, e.g. when ROM assignment, patch provided
10536 from Albert den Haan.

10691 * src/SDCCast.c (decorateType): unary plus compatible with all arithmetic
10692 types, not just integer types.
10693 * src/SDCCsymt.c (addSymChain): clarified error message when symbol is
10694 multiply defined with mismatching "at" address.

10779 * src/SDCCast.c (decorateType): disabled a transformation I added in
10780 revision 1.188 (access to fields of a structure at an absolute address);
10781 it breaks with bitfields, extern declarations, and gcse analysis.
10782 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10783 could be assigned through a pointer, so don't complain.
10784 * src/SDCCast.c (astErrors),

11384 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
11385 of const struct should be treated as if const themselves)
11387 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
11389 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

11404 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
11405 and restore of EA so that stack offsets to parameters are
11406 correct when using both critical and reentrant/stack-auto.
11407 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
11408 size (can be triggered in error if sloc is shared between
11409 different sized objects)
11410 * device/include/float.h: fixed macros to explicitly use
11411 unsigned long where needed
11413 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

11421 * src/SDCCsymt.c (sclsFromPtr),
11423 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11424 support for standard C idiom of memory mapped variables; for
11425 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11426 to xdata int at 0x1234 tempvar = 1.
11427 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
11428 provided by Akiya ISHIDA

11444 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11446 Fixed bug #621531 (const & volatile confusion in the type chain).
11447 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11448 refer to the const or volatile state of the pointer itself.
11460 * src/pic16/ralloc.c
11461 * support/regression/tests/const.c
11463 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11465 When checking for duplicated modules, use absolute paths
11466 instead of relative paths. Files changed:

11507 reported in bug #800609
11509 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
11511 * Top header beautifications in src/pic16 directory:
11512 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
11513 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
11514 pcoderegs.h, ralloc.c, ralloc.h
11515 * main.c: added top header and GPL license notice
11516 * pcode.c: fixed the if-conditional warning
11518 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11520 * device/lib/_mullong.c: replaced int by short for gcc
11522 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11524 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11525 and JUMPTABLE iCodes properly now (worked by accident before)
11526 * src/mcs51/gen.c (leftRightUseAcc),
11527 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11528 iCode properly now. Use getSize instead of nRegs since a & b
11529 aren't part of the nRegs tally.
11531 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11533 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11539 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
11540 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
11541 fetching of the pointer
11542 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11543 copied from genNearPointerSet()
11544 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11545 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11546 If they pop r0/r1 they must be called in the opposite order than aopOp().
11547 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11548 (resp. --stack-auto), prepared for --xstack
11550 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11552 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11554 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11556 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
11557 these ports have their own __sdcc_external_start()
11559 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11561 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11562 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11563 type for bits was changed. It resulted in bit variables becoming
11564 global, which is not permitted in PIC 14 assembly output.
11566 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11568 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11570 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11572 Z80 and MCS51 linkers complaint if a public symbol is defined
11573 in more than one library module:

11579 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11581 A few small changes that speed up the peephole optimizer.
11585 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11587 Try to make the peephole optimizer smarter by maintaining
11588 an association between the assembly source code and the
11589 iCodes that originated them. Put this information to use
11590 with a new peephole rule condition "notVolatile" so that
11591 the rules can be aggressive yet still safe.
11596 * src/mcs51/peeph.def
11598 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11602 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11603 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11604 if the left or right operand symbols have the accuse flag set.
11606 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11608 Changed the type of the result of the ! (NOT) operator to char;
11609 previously it returned the same type as the source. This allows
11610 us to eliminate all the genFloatNot functions (all of its target
11611 implementations were very buggy) since !float can use the same
11614 * src/SDCCicode.c (ast2iCode): ! returns char
11615 * src/mcs51/gen.c (genNot, genNotFloat),
11616 * src/ds390/gen.c (genNot, genNotFloat),
11617 * src/z80/gen.c (genNot, genNotFloat),
11618 * src/pic/gen.c (genNot, genNotFloat),
11619 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11623 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11624 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11625 during interrupts. Ensure WSAVE is located at a shared bank address.
11626 2. Fixed page selection in some places
11627 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11628 the registers name strings.
11629 4. Fixed "signed / unsigned compare" compiler warnings.
11630 5. The PIC port manages its own allocation of the general purpose
11631 registers, but makes no attempt to reuse them. As a result when
11632 compiling it soon runs out of general purpose registers. Some
11633 additional code was added to the files pcode.c and device.c to walk
11634 through the function call tree and rename the registers so that they
11644 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11645 genPlus() & genMinus() when the result is the same as left or right
11647 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11649 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11651 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11653 Made bitfield a distinct type from bit so that bitfields
11654 convert as per ANSI C and bits retain their traditional
11655 boolean style behaviour. Implemented bitfield support in
11663 * src/ds390/gen.c: bit v bitfield split
11664 * src/z80/gen.c: New support for bitfields
11665 * support/regression/tests/bitfields.c: reenabled z80,
11668 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11670 Rules 246.x, 247.x relate to bitfields, the others speed up
11671 access to xdata mapped I/O devices.
11673 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11675 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11677 Cleaned up genPackBits and genUnpackBits and added two helper
11678 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11679 for literal assignments in genPackBits (thanks to Frieder for
11685 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11687 Fixed bug #748310 (pointer to function type mishandled when the
11688 function name is omitted). Also fixed a SIGSEGV when a function
11689 attribute (reentrant, etc) is used on a non-function or on a
11690 function but misplaced before the parameter list.
11692 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11694 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11695 * support/Util/SDCCerr.h,
11696 * support/Util/SDCCerr.c: Added func attr misuse error msg
11698 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11700 Fixed bug #787649 by anonymous
11701 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11702 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11704 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11706 Fixed numerous bitfield problems.
11708 * src/SDCC.y: More bitfield related error checking

11711 * support/Util/SDCCerr.h,
11712 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
11713 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11714 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11715 * support/regression/tests/bitfields.c: tests added
11717 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11719 Made the constant following the "interrupt" keyword optional. If
11720 omitted, the function will not automatically be given an entry
11721 in the interrupt vector table (similar to #pragma NOIV, but
11722 less syntacticly kludgy). The interrupt number is also now
11723 range checked. Also fixed a bug in the high order bit example

11731 * support/Util/SDCCerr.h
11734 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11736 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11737 * src/SDCCicode.c (operandOperation): rewritten some ops
11738 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11739 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11741 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11742 be re-activated by defining REDUCE_LITERALS)
11743 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11744 unsigned, but are signed by default
11745 * src/SDCCval.c (constVal): rearranged
11746 * src/SDCCval.c (valMod): preliminary fix
11747 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11787 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11788 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11789 constants are unsigned; added recognition of "u" flag for unsigned
11790 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11791 * src/SDCCval.c (valDiv, valMod): fixed signdness
11792 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11793 signedness of modulo, left and right shift

12255 support for the PIc16 port in the ports table, when executing
12256 the compiler with no port specified on command line, a default
12257 port is selected with the new macro DEFAULT_PORT which is
12258 defined in port.h, in setDefaultOptions() linkOptions is removed
12259 from initialization assignment, since now it is a set,
12260 parseCmdLine uses setParseWithComma for linkOptions, in
12261 linkEdit() linkOptions are accessed with new function indexSet()
12262 which returns the i'th item of a set variable. See SDCCset.c, in
12263 linkEdit() when calling buildCmdLine(), added linkOptions as
12264 last argument. Now users can pass arguments to gplink via the

12279 gpasm complaining and test the linkage with gplink, _linkCmd and
12280 _asmCmd changed to be more gplink and gpasm friendly
12281 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12282 produced an error when parsed, peep rule 12 is added to utilize
12283 movff, but it is commented out since the pCode does not support
12284 yet a command with 2 address arguments

13343 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13344 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13346 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13347 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13349 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13351 * in /sdcc/as/mcs51/ changed these files in order to create an
13352 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13353 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13354 following files to include the previous two files: aslink.dsp,
13355 Makefile.aslink, Makefile.bcc, and Makefile.in.
13357 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13358 .adb instead of .cdb
13360 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13362 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13363 value from option --iram-size.
13365 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13367 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13370 2002-09-18 <wiml AT hhhh.org>
13372 * SDCClrange.h: exposed setFromRange() and setToRange()
13373 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13374 packRegsForAccUse() (bug 542397)
13375 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13376 multiple times and emitting the fetch operations more than once
13377 added aopGetUsesAcc() function to allow binary operators to
13378 fetch their operands in the correct order; made genMinus() emit
13379 compact code for X = LITERAL - Y
13381 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13382 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13383 sprintf() in line 1267.
13385 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13386 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13389 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13390 Changes to aslink (All the changes are marked with 'JCF'):
13392 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13395 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13396 area BSEG. Also moves, if possible, the DATA area down into the internal
13397 ram so more space is available.
13399 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13402 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13403 not bytes. Function summary() which creates a memory usage summary
13404 file with extension .mem. Reports of overlaping stack and small stack
13405 size. If the space for the stack is less than 16 bytes aslink trows a
13408 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13409 the 8051. Option 'y' for memory summary output file.
13411 Changes to sdcc (All the changes are marked with 'JCF'):
13413 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13415 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13416 overlaying area for it (uses RegBankUsed[4]).
13418 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13419 bank zero as used by default. By default aslink locates the stack
13420 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13421 the creation of the .mem file. Delegates the allocation of data area
13422 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13423 the begining of the stack area to aslink.
13425 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13426 glue() in SDCCglue.c creates an area for it.
13428 2002-09-03 Borut Razem <borut.razem AT siol.net>
13429 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13430 sdcc/src/pic/glue.c:
13431 introduced atexit() handler for teporay files removal in case of
13432 errors, assertions, ...
13434 2002-08-29 Borut Razem <borut.razem AT siol.net>
13435 * sdcc/support/cpp2/auto-host_vc_in.h:
13436 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13437 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13438 Maybe there is a similar problem with BORLANDC? It should be checked!
13440 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13441 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13442 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13443 was not executed, and the compiler (cl) launched a warning:
13444 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13446 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13447 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13449 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13450 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13452 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13453 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13454 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13455 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13456 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13457 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13458 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13459 - added Release configuration in VS projects
13460 - review of compiler an linker options
13461 - VC .exe files are generated in bin_vc directory, not to interfere
13462 with binaries generated from other projects (cygwin, mingw, bcc ...)
13464 * sdcc/src/yacc.dsp: added
13466 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13467 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13468 and insert the version number definitions from .version
13470 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13472 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13473 added - genarate auto-host.h using auto-host_vc_in.h as template
13476 removed from CVS, generated automatically
13478 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13479 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13481 2002-08-11 Borut Razem <borut.razem AT siol.net>
13482 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13484 2002-08-10 Borut Razem <borut.razem AT siol.net>
13485 * src/SDCCmain.c (main):
13486 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13487 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13488 The consequence was that some temporary files were not removed.
13491 unification of code in functions tempfilename() and tempfile():
13492 function tempnam() is defined in Visual Studio 6.0 and .NET
13494 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13496 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13497 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13498 - removed compiler command line option /WX: Treats all warnings as errors
13499 - update a list of source files, included into the project
13501 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13502 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13503 changed project type to Generic Project so that can be correcly converted to VS.NET project
13505 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13507 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13509 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13511 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13512 added return 0 statements after assert() to make compiler happy
13514 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13515 added newline in the def file to keep MSC compiler satisfied
13517 * sdcc/src/z80/gen.c:
13518 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13519 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13520 - solved MSC error in function aopDump()
13522 * sdcc_vc.h: define PREFIX as "\\sdcc"
13524 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13525 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13528 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13529 - Rewrote the register banking algorithm.
13530 - Added pCode live-range analysis to registers (for now, only non-used and
13531 singly-used registers optimized away)
13533 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13535 * 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.

13564 2002-03-28 Johan Knol <johan AT balder>
13566 * src/SDCCval.c: fixed bug #532436
13568 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13570 Added "char *Processor" field to the port structure.
13573 Added -p option. Allows port dependent processor to be specified.
13576 Initialized the new field char *Processor field to NULL in all ports
13579 Compiler generated registers for interrupt context saving
13580 were not getting allocated.
13582 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13585 Fixed left shift. Will promote the left side of a left shift
13586 if a) left shifting more than size of operand or b) when assigned
13587 to something size > size of left side
13589 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13591 tons of changes. Register allocation has been
13592 rewritten. Added customization for the various PICs. Flow
13593 analysis is restructured. ...

13604 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13606 2002-03-04 johanknol <johanknol AT manik>
13608 * /src/SDCCval.c: fixed
13610 const unsigned char arr[][2] = { { 0, 1 } };

13699 * sdcc/src/SDCCloop.c:
13700 Previous fix was not good. basic blocks that have "break" or "return" are
13701 not really partof a loop , but live ranges used in these blocks should
13702 be live thru the entire loop, so set partOfLoop but don't add them to
