440 mostly missing, but it's a start.
441 * support/regression/tests/bug-227710.c: fixed nonconforming use of
442 reserved identifier "__data".
444 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

488 immedDom() returning wrong block; probably fixes bug #1160833)
490 2005-03-20 Borut Razem <borut.razem AT siol.net>
492 * support/scripts/inc2h.pl: WIN32 port
494 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

498 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
500 * device/include/stdint.h: added
501 * device/lib/abs.c: added
502 * device/lib/labs.c: added
503 * device/include/stdlib.h: added abs() and labs() prototypes
504 * device/lib/libsdcc.lib: added abs and labs
505 * device/include/float.h,
506 * device/lib/_fsmul.c,
507 * device/lib/printf_fast.c,
508 * device/lib/printf_tiny.c: updated comments
510 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
512 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
515 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
517 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
518 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
520 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
522 * device/lib/printf_large.c: removed inline assembly for portability and
523 readability. Use printf_fast if speed or size are more important.
524 * src/pic16/gen.c: removed conditions around use of DEBUGpc
525 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
527 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
529 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
530 prevent compiler warning
532 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
534 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
535 moved to level 0 and declared as static. Also they are explicit
536 placed in access bank. This was necessery because some times they
537 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
538 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
539 optimizations. Currently only compare to unsigned char is implemented,
540 * src/pic16/gen.c: added fReturnIdx array,
541 * (struct resolvedIfx) is moved to gen.h and made public,
542 * (struct _G): added sregsAlloc and sregsAllocSet fields,
543 * (aopForSym): added an optimization to directly store in stack of
544 the operand of a SEND iCode,
545 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
546 but as registers instead (AOP_REG) using the fReturnIdx array,
547 * (pic16_freeAsmop): remove the freed register from the
549 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
551 * (pic16_popGetTempRegCond): changed function prototype, now
552 function takes also a bitVector argument v which holds the current
553 set of registers that are allocated for stack access by aopForSym,
554 registers allocated in aopForSym for accessing stack symbols are not
555 any more part of the functions usedRegs field,
556 * (genCall): some times aopOp is called for a stack variable to be
557 send, aopForSym might perform the push, if this is true make sure
558 that genCall doesn't push the variable twice by testing _G.resDirect,
559 * (genFunction): changed testing for unspecified interrupt number
560 from 256 to INTNO_UNSPEC,
561 * modified selection scheme of frame pointer generation. Previously
562 if function did use local registers a frame pointer was generated,
563 now a frame pointer is generated only if function has arguments
564 (that need PLUSW2 register access), or has stack arguments, or the
565 compiler is not instructed to omit the frame pointer,
566 * (genEndFunction): before restoring local registers that were saved
567 in the function preamble, also restore the registers that *might*
568 have been allocated for stack access,
569 * (genRet): removed some old comments,
570 * (genCmp, the active (RN's) version): added a call to the
571 pic16_genCmp_special function to perform the compare with a more
572 robust and optimized way,
573 * (genInline): a feature has been added in inline code generation,
574 which allows a wildcard variable substitution when writing inline
575 assembly. Code is incomplete and experimental therefore undocumented,
576 * (genCast): changed order of aopOp for result and right to allow
577 aopForSym to directly load the result if possible,
578 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
579 perform an optimized compare on some selected special occasions,
580 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
581 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
582 generate an IVT any more,
583 * src/pic16/main.c (pic16_optionsTable): added command line option
585 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
586 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
588 * src/pic16/NOTES: Raphael Neider added in list of active developers
589 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
590 jumptable_end to prevent bug #,
591 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
592 inCond and outCond fields,
593 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
594 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
595 turn off register spilling,
596 * (packRegsForOneUse): synced with other ports' versions although it
597 is not used currently,
598 * (pic16_packRegisters): added an optimization while reading
599 structure bitfields, some registers may be saved (malloc code is
600 decreased by 80 bytes)
602 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
604 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
605 left is a bitfield, if yes, then don't optimize assignment. Perhaps
606 this can be optimized more?
608 2005-03-10 Raphael Neider <rneider AT web.de>
610 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
611 genNearPointerGet): (hopefully) fixed access to bitfields via
612 pointers (p->bitN = x; and x = p->bitN; failed)

657 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
658 to keep the correct label reference count when adding/removing references
659 to labels. A peephole file using this is appended to patch #1144962.

897 operands (genAddLit expects the iCode's operands to swapped as
898 well), fixed leftover bytes (crashed for short left operands)

1282 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1284 * added libc directory. The current version of LibC contains string
1285 functions, ctype functions and macros and some functions of the
1286 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1287 be extensively tested in the future. Standard disclaimer here.
1288 Library is not automatically build yet. But one can build it by

1300 * (pic16_storeForReturn): optimized return of 0,
1301 * (genCmp): experimental code for new genCmp which uses PIC18's
1302 special compare&skip instructions. Initial tests fail some times
1303 with variables grater than 1 byte in size, so new code is disabled,
1304 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1306 * (genCast): began a fix to optimize the casting of a bit to another
1307 bit, now assigning a bitfield to another bitfield will fail, sorry,

1315 * (isBankInstruction): modified to return 0 for no banking instruction,
1316 and 1 for banking instruction,
1317 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1318 caused stop processing pCodes after a inline assembly block,
1319 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1321 registers when it shouldn't,
1322 * src/pic16/ralloc.c (allocReg): add preliminary support for
1323 supporting a limited set of temporary registers,
1325 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1327 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1328 genDataPointerSet): ensure assignments always copy in MSB to LSB
1330 (loadRegFromAop): recognize CLRH optimization,
1331 (genFunction): optimize RECEIVE iCodes in reentrant functions
1333 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1335 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1336 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1338 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
1339 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be

4330 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4332 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4333 loaded with the linker search paths (-L arguments) and the libraries
4334 to be linked with the current source (-l arguments). Changes
4335 currently will affect only the pic16 port.
4336 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4337 include path the port specific paths and port specific libraries,
4338 * gplink command now contains the $3 argument,
4339 * src/pic16/device.h,
4340 * src/pic16/device.c,: structure PIC_device is made public and
4341 renamed to PIC16_device, the same for variable Pics which is renamed

4356 Documenting changes from previous commits.
4357 * configure.in (version 1.56),
4358 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4359 when generating output files to configure the pic16 library,
4360 but now I've commented it out, since gputils aren't installed in the
4361 SF compile farm, so library won't compile
4363 * device/lib/Makefile.in (version 1.56): initially I've added in
4364 target 'all' the prerequestive 'model-pic16' so it compiled the
4365 pic16 library, but now I've commented it out for the same reasons
4367 * added targets 'model-pic16' and 'objects-pic16' to compile the
4369 * added target 'port-specific-objects-pic16' to handle the
4370 generated libraries and copy them into the build/ directory
4371 * added target 'clean-intermediate-pic16' to clean intermediate
4372 files into pic16 directory
4373 * in target 'installdirs' added line to create directory pic16 in
4374 the installation path
4376 * device/include/Makefile.in (version 1.11): in target 'install'
4377 added lines to copy all header files to installation path,
4378 * in target 'installdirs' added line create directory for pic16
4379 headers in the installation path

4394 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4395 option so that it actually works. Made it specific to the z80, since
4396 the gbz80 doesn't have these kinds of I/O ports.
4398 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4400 * device/include/z180.h,

4424 via literal number. The symbol is placed in the corresponding
4425 position of the data ram
4426 * (pic16_dump_section): relocatable and absolute uninitialized
4427 data are now emitted in sorted order to reduce section naming,
4428 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4429 weren't marked as being in the access bank,
4431 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4433 Added portion of GNU PIC Library under the directory
4434 device/include/pic16 and device/lib/pic16. These files
4435 contain the declarations of SFRs for the PIC18Fxx2 devices.
4436 The directory is initialized via configure from toplevel.
4438 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4440 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4447 2004-01-12 Borut Razem <borut.razem AT siol.net>
4449 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
4450 doc/sdccman.lyx: upper case pragmas are deprecated
4452 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4454 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results

4465 * doc/sdccman.lyx: Moved and added some sections, small changes
4466 all over. Telling LaTeX to be less strict with word spacing
4467 to better keep the right margin. Changed some notes about
4468 maintainance of the ports in section 3.2.1 - is it OK like this?
4470 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4472 SDCC source changes:
4473 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4507 UPPER for immediate operands,
4508 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4510 * src/pic16/peeph.def: all peepholes with movff are commented out,
4511 because there is a problem in the pcode peep optimizer,
4512 * src/pic16/ralloc.c: the register allocator can now reuse local

4599 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4601 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4603 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4605 include information about variables allocated to the overlay
4608 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4610 * as/mcs51/lkmain.c: Help about -Y option

4622 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4624 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4625 (default behaviour).
4627 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4629 A python script to validate compiler diagnostic messages. It can be
4630 used to verify that sdcc complains about bad c source code and
4631 gives a good location of the error.
4632 * support/valdiag/Makefile,
4633 * support/valdiag/valdiag.py,
4634 * support/valdiag/tests/*
4636 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4649 * src/common.h: added ifndef/define/endif macros
4650 around the header file.
4651 Bug reported from Jesus Calvino-Fraga
4653 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4655 * sdcc.spec: updated
4656 * device/include/Makefile.in: don't install CVS directories
4657 * device/lib/Makefile.in: added removal of CVS directories after install
4658 * doc/Makefile: fixed install, added local_icons
4659 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4660 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4661 * src/ds390/gen.c (genRightShift): fixed bug #870788
4662 * src/SDCCast.c (decorateType): fixed bug #870781
4664 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4666 PIC16 port related changes:
4667 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4668 added variable stackPos,
4670 * gen.c: genCall, assignResultValue: added support for
4671 pushing/retrieving function parameters to/from stack,
4672 genFunction,genEndFunction: setup stack frame for the
4674 genAddrOf: will be changed according to bug 863624
4676 * added files genutils.c and genutils.h which contain gen*
4677 debugged and optimised functions extracted from gen.c
4679 * glue.c: added variable 'externs' which holds extern symbols,
4680 pic16emitRegularMap: is modified to properly handle relocatable
4681 symbols under the new scheme,
4682 pic16createInterruptVect: is modified
4683 pic16printPublics: is modified to emit 'global' assembler directives,
4684 added pic16_printExterns to print extern symbols,
4685 pic16glue: initializes stack/frame pointer in the beginning of
4686 the assembly output. Temporary hack, will be corrected later,
4687 because gplink yet does not support stack and SDCC does not
4688 yet support a type of crt0.o object to create the final binary.
4690 * Removed many lines that contain 8051 legacy code.
4691 * The code is finally placed under a 'code' directive.
4692 * Added port specific options.
4694 * _process_pragma: simplified since now we do not need *special*
4695 include file to define SFR registers. But a separate header
4696 will be needed. This will be developed later.
4697 * _pic16_parseOptions: added, parses port specific options:
4698 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4699 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4700 --preplace-udata-with=
4702 * _pic16_setDefaultOptions: modified to initialize section names,
4703 but hack is temporarly out of order since it needs improvement.
4704 * _pic16_genAssemblerPreamble: configuration words are emitted by
4705 their address instead of their name. This part is incomplete and
4706 supports only the 18Fxx2 devices. Other devices will emit an error
4707 during assembly since they do not contain the same set of config
4709 * _pic16_genIVT: is modified,
4711 * pcode.c: added definitions for some hardware registers that are needed
4713 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4714 All PCI entries are updated. Now LFSR is supported.
4715 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4716 * added pic16_newpCodeOpLit2 to support instructions with
4717 two literal arguments
4718 * pic16_pCode2str: corrected code that emits assembler instructions
4719 with two literal operands and those that have an access bit modifier
4720 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4721 this fixes a bug which caused some labels to be lost, when an
4722 assembler directive was added, i.e. banksel,
4723 * pic16_FixRegisterBanking: improved logic that causes the insertion
4725 * InlineFunction: functions that are called once, are not any more
4726 inlined. This can be a port option in the future,
4728 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4730 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4731 hold the corresponding uninitialized symbols,
4732 * pic16_allocProcessorRegister: registers have explicit marked the
4734 * pic16_allocInternalRegister: registers are explicit marked as
4736 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4737 processing list, so bit registers were lost,
4740 * ralloc.h: added field 'accessBank' and original symbol operand
4741 in register definition,
4742 * removed the field isMapped from register definition,
4744 ** Several functions have been removed from various sources:
4745 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4746 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4747 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4748 pic16_assignRelocatableRegisters
4750 ** others have been introduced:
4751 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4752 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4754 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4756 * support/scripts/inc2h.pl: changed definition of BIT_AT
4757 to emit 'sbit at' instead of 'bit at'. This was a request.
4759 PIC16 port related preliminary changes:
4760 * gen.c: prefixed function popRegFromString with
4761 pic16_ and all references to it corrected
4762 * pcode.c: all pic16_pc_* hardware registers prefixed
4763 with underscore (_),
4764 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4765 * ralloc.c: newReg(): when register is REG_SFR then
4766 set address to rIdx,
4767 pic16_allocProcessorRegister(): marks register wasUsed=0
4768 pic16_writeUsedRegs(): added a call to assign processor
4769 registers via pic16_assignFixedRegisters
4771 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4773 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4774 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4775 variables in unused register banks. Also the SSEG is placed
4776 wherever there is enough space for it, and IDATA can be anywhere
4777 in internal RAM. For now compile using -Wl-Y[stack_size].
4778 The mem file is different for this option as well, since it
4779 makes no sense of talking about DSEG lenght.
4781 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4783 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4784 in certain cases, e.g. when ROM assignment, patch provided
4785 from Albert den Haan.
4787 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4930 * src/mcs51/peephole.def,
4931 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4932 (allows non-interrupt and interrupt code to safely compete for a resource

5810 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5811 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5812 type for bits was changed. It resulted in bit variables becoming

5830 A few small changes that speed up the peephole optimizer.
5834 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5836 Try to make the peephole optimizer smarter by maintaining
5837 an association between the assembly source code and the
5838 iCodes that originated them. Put this information to use
5839 with a new peephole rule condition "notVolatile" so that
5840 the rules can be aggressive yet still safe.
5845 * src/mcs51/peeph.def
5847 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5851 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5852 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5853 if the left or right operand symbols have the accuse flag set.
5855 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5857 Changed the type of the result of the ! (NOT) operator to char;
5858 previously it returned the same type as the source. This allows
5859 us to eliminate all the genFloatNot functions (all of its target
5860 implementations were very buggy) since !float can use the same
5863 * src/SDCCicode.c (ast2iCode): ! returns char

5872 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5873 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5874 during interrupts. Ensure WSAVE is located at a shared bank address.
5875 2. Fixed page selection in some places
5876 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5877 the registers name strings.
5878 4. Fixed "signed / unsigned compare" compiler warnings.
5879 5. The PIC port manages its own allocation of the general purpose
5880 registers, but makes no attempt to reuse them. As a result when
5881 compiling it soon runs out of general purpose registers. Some
5882 additional code was added to the files pcode.c and device.c to walk
5883 through the function call tree and rename the registers so that they
5893 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5900 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5902 Made bitfield a distinct type from bit so that bitfields
5903 convert as per ANSI C and bits retain their traditional
5904 boolean style behaviour. Implemented bitfield support in
5912 * src/ds390/gen.c: bit v bitfield split
5913 * src/z80/gen.c: New support for bitfields
5914 * support/regression/tests/bitfields.c: reenabled z80,
5917 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5919 Rules 246.x, 247.x relate to bitfields, the others speed up
5920 access to xdata mapped I/O devices.
5922 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5924 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5926 Cleaned up genPackBits and genUnpackBits and added two helper

5936 Fixed bug #748310 (pointer to function type mishandled when the
5937 function name is omitted). Also fixed a SIGSEGV when a function
5938 attribute (reentrant, etc) is used on a non-function or on a
5939 function but misplaced before the parameter list.

5968 Made the constant following the "interrupt" keyword optional. If
5969 omitted, the function will not automatically be given an entry
5970 in the interrupt vector table (similar to #pragma NOIV, but
5971 less syntacticly kludgy). The interrupt number is also now
5972 range checked. Also fixed a bug in the high order bit example
5979 * support/Util/SDCCerr.c
5980 * support/Util/SDCCerr.h
5983 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5991 be re-activated by defining REDUCE_LITERALS)
5992 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5993 unsigned, but are signed by default
5994 * src/SDCCval.c (constVal): rearranged
5995 * src/SDCCval.c (valMod): preliminary fix
5996 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6039 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6040 * src/SDCCval.c (valDiv, valMod): fixed signdness
6041 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6042 signedness of modulo, left and right shift
6043 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

6505 the compiler with no port specified on command line, a default
6506 port is selected with the new macro DEFAULT_PORT which is
6507 defined in port.h, in setDefaultOptions() linkOptions is removed
6508 from initialization assignment, since now it is a set,
6509 parseCmdLine uses setParseWithComma for linkOptions, in
6510 linkEdit() linkOptions are accessed with new function indexSet()

7578 2003-01-04 <johan AT balder>
7580 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7582 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7583 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7585 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7595 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7596 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7598 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7600 * in \sdcc\as\mcs51\ changed these files in order to create an
7601 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7602 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7603 following files to include the previous two files: aslink.dsp,
7604 Makefile.aslink, Makefile.bcc, and Makefile.in.
7606 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7607 .adb instead of .cdb
7609 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7611 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7612 value from option --iram-size.
7614 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7616 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7619 2002-09-18 <wiml AT hhhh.org>
7621 * SDCClrange.h: exposed setFromRange() and setToRange()
7622 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7623 packRegsForAccUse() (bug 542397)
7624 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7625 multiple times and emitting the fetch operations more than once
7626 added aopGetUsesAcc() function to allow binary operators to
7627 fetch their operands in the correct order; made genMinus() emit
7628 compact code for X = LITERAL - Y
7630 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7631 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7632 sprintf() in line 1267.
7634 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7635 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7638 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7639 Changes to aslink (All the changes are marked with 'JCF'):
7641 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7644 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7645 area BSEG. Also moves, if possible, the DATA area down into the internal
7646 ram so more space is available.
7648 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7651 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7652 not bytes. Function summary() which creates a memory usage summary
7653 file with extension .mem. Reports of overlaping stack and small stack
7654 size. If the space for the stack is less than 16 bytes aslink trows a
7657 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7658 the 8051. Option 'y' for memory summary output file.
7660 Changes to sdcc (All the changes are marked with 'JCF'):
7662 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7664 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7665 overlaying area for it (uses RegBankUsed[4]).
7667 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7668 bank zero as used by default. By default aslink locates the stack
7669 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7670 the creation of the .mem file. Delegates the allocation of data area
7671 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7672 the begining of the stack area to aslink.
7674 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7675 glue() in SDCCglue.c creates an area for it.
7677 2002-09-03 Borut Razem <borut.razem AT siol.net>
7678 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7679 sdcc/src/pic/glue.c:
7680 introduced atexit() handler for teporay files removal in case of
7681 errors, assertions, ...
7683 2002-08-29 Borut Razem <borut.razem AT siol.net>
7684 * sdcc/support/cpp2/auto-host_vc_in.h:
7685 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7686 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7687 Maybe there is a similar problem with BORLANDC? It should be checked!
7689 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7690 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7691 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7692 was not executed, and the compiler (cl) launched a warning:
7693 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7695 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7696 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7698 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7699 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7701 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7702 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7703 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7704 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7705 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7706 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7707 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7708 - added Release configuration in VS projects
7709 - review of compiler an linker options
7710 - VC .exe files are generated in bin_vc directory, not to interfere
7711 with binaries generated from other projects (cygwin, mingw, bcc ...)
7713 * sdcc/src/yacc.dsp: added
7715 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7716 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7717 and insert the version number definitions from .version
7719 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7721 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7722 added - genarate auto-host.h using auto-host_vc_in.h as template
7725 removed from CVS, generated automatically
7727 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7728 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7730 2002-08-11 Borut Razem <borut.razem AT siol.net>
7731 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7733 2002-08-10 Borut Razem <borut.razem AT siol.net>
7734 * src/SDCCmain.c (main):
7735 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7736 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7737 The consequence was that some temporary files were not removed.
7740 unification of code in functions tempfilename() and tempfile():
7741 function tempnam() is defined in Visual Studio 6.0 and .NET
7743 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7745 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7746 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7747 - removed compiler command line option /WX: Treats all warnings as errors
7748 - update a list of source files, included into the project
7750 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7751 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7752 changed project type to Generic Project so that can be correcly converted to VS.NET project
7754 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7756 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7758 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7760 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7761 added return 0 statements after assert() to make compiler happy
7763 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7764 added newline in the def file to keep MSC compiler satisfied
7766 * sdcc/src/z80/gen.c:
7767 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7768 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7769 - solved MSC error in function aopDump()
7771 * sdcc_vc.h: define PREFIX as "\\sdcc"
7773 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7774 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7776 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7777 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7778 - Rewrote the register banking algorithm.
7779 - Added pCode live-range analysis to registers (for now, only non-used and
7780 singly-used registers optimized away)
7782 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7784 * 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.
7786 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7787 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

7809 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7811 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7813 2002-03-28 Johan Knol <johan AT balder>
7815 * src/SDCCval.c: fixed bug #532436
7817 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7819 Added "char *Processor" field to the port structure.
7822 Added -p option. Allows port dependent processor to be specified.
7825 Initialized the new field char *Processor field to NULL in all ports
7828 Compiler generated registers for interrupt context saving
7829 were not getting allocated.
7831 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7834 Fixed left shift. Will promote the left side of a left shift
7835 if a) left shifting more than size of operand or b) when assigned
7836 to something size > size of left side
7838 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7840 tons of changes. Register allocation has been
7841 rewritten. Added customization for the various PICs. Flow
7842 analysis is restructured. ...
7848 Added. device.c is a PIC port hack to accomodate variations
7851 2002-03-13 Michael Hope <michaelh AT vroom>
7853 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7855 2002-03-04 johanknol <johanknol AT manik>
7857 * /src/SDCCval.c: fixed
7859 const unsigned char arr[][2] = { { 0, 1 } };
7860 t18.c:1: error: Initializer element is not constant
7862 2002-03-04 bela <bela AT manik>
7864 * /device/include/mcs51reg.h:
