444 on rIfx (genCmp was broken)
446 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
448 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
449 * src/z80/main.c (_keywords[]),
450 * src/SDCCglobal.h (struct options),
452 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
453 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
454 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
455 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
456 always available in leading double underscore form. The C99 support is
457 mostly missing, but it's a start.
458 * support/regression/tests/bug-227710.c: fixed nonconforming use of
459 reserved identifier "__data".
461 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

469 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
471 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
474 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

502 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
503 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
504 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
505 immedDom() returning wrong block; probably fixes bug #1160833)
507 2005-03-20 Borut Razem <borut.razem AT siol.net>
509 * support/scripts/inc2h.pl: WIN32 port
511 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

529 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
532 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
534 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
535 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
537 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
539 * device/lib/printf_large.c: removed inline assembly for portability and
540 readability. Use printf_fast if speed or size are more important.
541 * src/pic16/gen.c: removed conditions around use of DEBUGpc
542 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
544 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
546 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
547 prevent compiler warning
549 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
551 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
552 moved to level 0 and declared as static. Also they are explicit
553 placed in access bank. This was necessery because some times they
554 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
555 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
556 optimizations. Currently only compare to unsigned char is implemented,
557 * src/pic16/gen.c: added fReturnIdx array,
558 * (struct resolvedIfx) is moved to gen.h and made public,
559 * (struct _G): added sregsAlloc and sregsAllocSet fields,
560 * (aopForSym): added an optimization to directly store in stack of
561 the operand of a SEND iCode,
562 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
563 but as registers instead (AOP_REG) using the fReturnIdx array,
564 * (pic16_freeAsmop): remove the freed register from the
566 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
568 * (pic16_popGetTempRegCond): changed function prototype, now
569 function takes also a bitVector argument v which holds the current
570 set of registers that are allocated for stack access by aopForSym,
571 registers allocated in aopForSym for accessing stack symbols are not
572 any more part of the functions usedRegs field,
573 * (genCall): some times aopOp is called for a stack variable to be
574 send, aopForSym might perform the push, if this is true make sure
575 that genCall doesn't push the variable twice by testing _G.resDirect,
576 * (genFunction): changed testing for unspecified interrupt number
577 from 256 to INTNO_UNSPEC,
578 * modified selection scheme of frame pointer generation. Previously
579 if function did use local registers a frame pointer was generated,
580 now a frame pointer is generated only if function has arguments
581 (that need PLUSW2 register access), or has stack arguments, or the
582 compiler is not instructed to omit the frame pointer,
583 * (genEndFunction): before restoring local registers that were saved
584 in the function preamble, also restore the registers that *might*
585 have been allocated for stack access,
586 * (genRet): removed some old comments,
587 * (genCmp, the active (RN's) version): added a call to the
588 pic16_genCmp_special function to perform the compare with a more
589 robust and optimized way,
590 * (genInline): a feature has been added in inline code generation,
591 which allows a wildcard variable substitution when writing inline
592 assembly. Code is incomplete and experimental therefore undocumented,
593 * (genCast): changed order of aopOp for result and right to allow
594 aopForSym to directly load the result if possible,
595 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
596 perform an optimized compare on some selected special occasions,
597 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
598 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
599 generate an IVT any more,
600 * src/pic16/main.c (pic16_optionsTable): added command line option
602 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
603 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
605 * src/pic16/NOTES: Raphael Neider added in list of active developers
606 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
607 jumptable_end to prevent bug #,
608 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
609 inCond and outCond fields,
610 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
611 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
612 turn off register spilling,
613 * (packRegsForOneUse): synced with other ports' versions although it
614 is not used currently,
615 * (pic16_packRegisters): added an optimization while reading
616 structure bitfields, some registers may be saved (malloc code is
617 decreased by 80 bytes)
619 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
621 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
622 left is a bitfield, if yes, then don't optimize assignment. Perhaps
623 this can be optimized more?
625 2005-03-10 Raphael Neider <rneider AT web.de>
627 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
628 genNearPointerGet): (hopefully) fixed access to bitfields via
629 pointers (p->bitN = x; and x = p->bitN; failed)

675 to keep the correct label reference count when adding/removing references
676 to labels. A peephole file using this is appended to patch #1144962.

1264 generated for switch statements. For now you need to set the
1265 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1266 Now 4 algorithms for mcs51 jumptable generation are used:
1267 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1299 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1301 * added libc directory. The current version of LibC contains string
1302 functions, ctype functions and macros and some functions of the
1303 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1304 be extensively tested in the future. Standard disclaimer here.
1305 Library is not automatically build yet. But one can build it by
1306 invoking 'make' inside the libc directory.

1316 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1317 * (pic16_storeForReturn): optimized return of 0,
1318 * (genCmp): experimental code for new genCmp which uses PIC18's
1319 special compare&skip instructions. Initial tests fail some times
1320 with variables grater than 1 byte in size, so new code is disabled,
1321 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1323 * (genCast): began a fix to optimize the casting of a bit to another
1324 bit, now assigning a bitfield to another bitfield will fail, sorry,
1325 * src/pic16/main.c: disabled the use of lr-support feature,
1326 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1329 bits with offset (case PO_GPR_BIT),
1330 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1332 * (isBankInstruction): modified to return 0 for no banking instruction,
1333 and 1 for banking instruction,
1334 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1335 caused stop processing pCodes after a inline assembly block,
1336 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1337 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1338 registers when it shouldn't,
1339 * src/pic16/ralloc.c (allocReg): add preliminary support for

4347 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4349 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4350 loaded with the linker search paths (-L arguments) and the libraries
4351 to be linked with the current source (-l arguments). Changes
4352 currently will affect only the pic16 port.
4353 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4354 include path the port specific paths and port specific libraries,
4355 * gplink command now contains the $3 argument,
4356 * src/pic16/device.h,
4357 * src/pic16/device.c,: structure PIC_device is made public and
4358 renamed to PIC16_device, the same for variable Pics which is renamed

4373 Documenting changes from previous commits.
4374 * configure.in (version 1.56),
4375 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4376 when generating output files to configure the pic16 library,
4377 but now I've commented it out, since gputils aren't installed in the
4378 SF compile farm, so library won't compile
4380 * device/lib/Makefile.in (version 1.56): initially I've added in
4381 target 'all' the prerequestive 'model-pic16' so it compiled the
4382 pic16 library, but now I've commented it out for the same reasons
4384 * added targets 'model-pic16' and 'objects-pic16' to compile the
4386 * added target 'port-specific-objects-pic16' to handle the
4387 generated libraries and copy them into the build/ directory
4388 * added target 'clean-intermediate-pic16' to clean intermediate
4389 files into pic16 directory
4390 * in target 'installdirs' added line to create directory pic16 in
4391 the installation path
4393 * device/include/Makefile.in (version 1.11): in target 'install'
4394 added lines to copy all header files to installation path,
4395 * in target 'installdirs' added line create directory for pic16
4396 headers in the installation path

4411 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4412 option so that it actually works. Made it specific to the z80, since
4413 the gbz80 doesn't have these kinds of I/O ports.
4415 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4417 * device/include/z180.h,

4441 via literal number. The symbol is placed in the corresponding
4442 position of the data ram
4443 * (pic16_dump_section): relocatable and absolute uninitialized
4444 data are now emitted in sorted order to reduce section naming,
4445 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4446 weren't marked as being in the access bank,
4448 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4450 Added portion of GNU PIC Library under the directory
4451 device/include/pic16 and device/lib/pic16. These files
4452 contain the declarations of SFRs for the PIC18Fxx2 devices.
4453 The directory is initialized via configure from toplevel.

4483 all over. Telling LaTeX to be less strict with word spacing
4484 to better keep the right margin. Changed some notes about
4485 maintainance of the ports in section 3.2.1 - is it OK like this?
4487 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4525 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4527 * src/pic16/peeph.def: all peepholes with movff are commented out,
4528 because there is a problem in the pcode peep optimizer,
4529 * src/pic16/ralloc.c: the register allocator can now reuse local

4639 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4641 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4642 (default behaviour).
4644 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4646 A python script to validate compiler diagnostic messages. It can be
4647 used to verify that sdcc complains about bad c source code and
4648 gives a good location of the error.
4649 * support/valdiag/Makefile,
4650 * support/valdiag/valdiag.py,
4651 * support/valdiag/tests/*
4653 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4668 Bug reported from Jesus Calvino-Fraga
4670 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4672 * sdcc.spec: updated
4673 * device/include/Makefile.in: don't install CVS directories
4674 * device/lib/Makefile.in: added removal of CVS directories after install
4675 * doc/Makefile: fixed install, added local_icons
4676 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4677 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4678 * src/ds390/gen.c (genRightShift): fixed bug #870788
4679 * src/SDCCast.c (decorateType): fixed bug #870781
4681 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4683 PIC16 port related changes:
4684 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4685 added variable stackPos,
4687 * gen.c: genCall, assignResultValue: added support for
4688 pushing/retrieving function parameters to/from stack,
4689 genFunction,genEndFunction: setup stack frame for the
4691 genAddrOf: will be changed according to bug 863624
4693 * added files genutils.c and genutils.h which contain gen*
4694 debugged and optimised functions extracted from gen.c
4696 * glue.c: added variable 'externs' which holds extern symbols,
4697 pic16emitRegularMap: is modified to properly handle relocatable
4698 symbols under the new scheme,
4699 pic16createInterruptVect: is modified
4700 pic16printPublics: is modified to emit 'global' assembler directives,
4701 added pic16_printExterns to print extern symbols,
4702 pic16glue: initializes stack/frame pointer in the beginning of
4703 the assembly output. Temporary hack, will be corrected later,
4704 because gplink yet does not support stack and SDCC does not
4705 yet support a type of crt0.o object to create the final binary.
4707 * Removed many lines that contain 8051 legacy code.
4708 * The code is finally placed under a 'code' directive.
4709 * Added port specific options.
4711 * _process_pragma: simplified since now we do not need *special*
4712 include file to define SFR registers. But a separate header
4713 will be needed. This will be developed later.
4714 * _pic16_parseOptions: added, parses port specific options:
4715 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4716 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4717 --preplace-udata-with=
4719 * _pic16_setDefaultOptions: modified to initialize section names,
4720 but hack is temporarly out of order since it needs improvement.
4721 * _pic16_genAssemblerPreamble: configuration words are emitted by
4722 their address instead of their name. This part is incomplete and
4723 supports only the 18Fxx2 devices. Other devices will emit an error
4724 during assembly since they do not contain the same set of config
4726 * _pic16_genIVT: is modified,
4728 * pcode.c: added definitions for some hardware registers that are needed
4730 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4731 All PCI entries are updated. Now LFSR is supported.
4732 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4733 * added pic16_newpCodeOpLit2 to support instructions with
4734 two literal arguments
4735 * pic16_pCode2str: corrected code that emits assembler instructions
4736 with two literal operands and those that have an access bit modifier
4737 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4738 this fixes a bug which caused some labels to be lost, when an
4739 assembler directive was added, i.e. banksel,
4740 * pic16_FixRegisterBanking: improved logic that causes the insertion
4742 * InlineFunction: functions that are called once, are not any more
4743 inlined. This can be a port option in the future,
4745 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4747 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4748 hold the corresponding uninitialized symbols,
4749 * pic16_allocProcessorRegister: registers have explicit marked the
4751 * pic16_allocInternalRegister: registers are explicit marked as
4753 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4754 processing list, so bit registers were lost,
4757 * ralloc.h: added field 'accessBank' and original symbol operand
4758 in register definition,
4759 * removed the field isMapped from register definition,
4761 ** Several functions have been removed from various sources:
4762 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4763 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4764 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4765 pic16_assignRelocatableRegisters
4767 ** others have been introduced:
4768 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4769 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4771 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4773 * support/scripts/inc2h.pl: changed definition of BIT_AT
4774 to emit 'sbit at' instead of 'bit at'. This was a request.
4776 PIC16 port related preliminary changes:
4777 * gen.c: prefixed function popRegFromString with
4778 pic16_ and all references to it corrected
4779 * pcode.c: all pic16_pc_* hardware registers prefixed
4780 with underscore (_),
4781 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4782 * ralloc.c: newReg(): when register is REG_SFR then
4783 set address to rIdx,
4784 pic16_allocProcessorRegister(): marks register wasUsed=0
4785 pic16_writeUsedRegs(): added a call to assign processor
4786 registers via pic16_assignFixedRegisters
4788 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4790 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4791 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4792 variables in unused register banks. Also the SSEG is placed
4793 wherever there is enough space for it, and IDATA can be anywhere
4794 in internal RAM. For now compile using -Wl-Y[stack_size].
4795 The mem file is different for this option as well, since it
4796 makes no sense of talking about DSEG lenght.
4798 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4800 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4801 in certain cases, e.g. when ROM assignment, patch provided
4802 from Albert den Haan.
4804 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4946 SDCC_NOGENRAMCLEAR to disable this.
4947 * src/mcs51/peephole.def,
4948 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4949 (allows non-interrupt and interrupt code to safely compete for a resource
4950 without the non-interrupt code having to disable interrupts)
4952 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4954 * src/SDCCicode.c (geniCodeAdd),

4974 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4976 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

5047 it breaks with bitfields, extern declarations, and gcse analysis.
5048 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5049 could be assigned through a pointer, so don't complain.

5827 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5828 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5829 type for bits was changed. It resulted in bit variables becoming

5847 A few small changes that speed up the peephole optimizer.
5851 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5853 Try to make the peephole optimizer smarter by maintaining
5854 an association between the assembly source code and the
5855 iCodes that originated them. Put this information to use
5856 with a new peephole rule condition "notVolatile" so that
5857 the rules can be aggressive yet still safe.
5862 * src/mcs51/peeph.def
5864 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5868 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5869 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5870 if the left or right operand symbols have the accuse flag set.
5872 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5874 Changed the type of the result of the ! (NOT) operator to char;
5875 previously it returned the same type as the source. This allows
5876 us to eliminate all the genFloatNot functions (all of its target
5877 implementations were very buggy) since !float can use the same
5880 * src/SDCCicode.c (ast2iCode): ! returns char

5889 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5890 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5891 during interrupts. Ensure WSAVE is located at a shared bank address.
5892 2. Fixed page selection in some places
5893 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5894 the registers name strings.
5895 4. Fixed "signed / unsigned compare" compiler warnings.
5896 5. The PIC port manages its own allocation of the general purpose
5897 registers, but makes no attempt to reuse them. As a result when
5898 compiling it soon runs out of general purpose registers. Some
5899 additional code was added to the files pcode.c and device.c to walk
5900 through the function call tree and rename the registers so that they
5910 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5917 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5919 Made bitfield a distinct type from bit so that bitfields
5920 convert as per ANSI C and bits retain their traditional
5921 boolean style behaviour. Implemented bitfield support in
5929 * src/ds390/gen.c: bit v bitfield split
5930 * src/z80/gen.c: New support for bitfields
5931 * support/regression/tests/bitfields.c: reenabled z80,
5934 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5936 Rules 246.x, 247.x relate to bitfields, the others speed up
5937 access to xdata mapped I/O devices.
5939 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5941 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5943 Cleaned up genPackBits and genUnpackBits and added two helper
5944 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5945 for literal assignments in genPackBits (thanks to Frieder for
5951 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5953 Fixed bug #748310 (pointer to function type mishandled when the
5954 function name is omitted). Also fixed a SIGSEGV when a function
5955 attribute (reentrant, etc) is used on a non-function or on a
5956 function but misplaced before the parameter list.
5958 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5960 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5961 * support/Util/SDCCerr.h,

5985 Made the constant following the "interrupt" keyword optional. If
5986 omitted, the function will not automatically be given an entry
5987 in the interrupt vector table (similar to #pragma NOIV, but
5988 less syntacticly kludgy). The interrupt number is also now
5989 range checked. Also fixed a bug in the high order bit example
5996 * support/Util/SDCCerr.c

6520 messages from optionsTable when a port is not configured, added
6521 support for the PIc16 port in the ports table, when executing
6522 the compiler with no port specified on command line, a default
6523 port is selected with the new macro DEFAULT_PORT which is
6524 defined in port.h, in setDefaultOptions() linkOptions is removed
6525 from initialization assignment, since now it is a set,
6526 parseCmdLine uses setParseWithComma for linkOptions, in
6527 linkEdit() linkOptions are accessed with new function indexSet()
6528 which returns the i'th item of a set variable. See SDCCset.c, in

7589 * src/SDCCicode.c: fixed array add
7591 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7592 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7593 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7595 2003-01-04 <johan AT balder>
7597 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7599 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7600 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7602 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7603 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7610 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7612 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7613 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7615 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7617 * in \sdcc\as\mcs51\ changed these files in order to create an
7618 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7619 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7620 following files to include the previous two files: aslink.dsp,
7621 Makefile.aslink, Makefile.bcc, and Makefile.in.
7623 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7624 .adb instead of .cdb
7626 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7628 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7629 value from option --iram-size.
7631 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7633 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7636 2002-09-18 <wiml AT hhhh.org>
7638 * SDCClrange.h: exposed setFromRange() and setToRange()
7639 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7640 packRegsForAccUse() (bug 542397)
7641 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7642 multiple times and emitting the fetch operations more than once
7643 added aopGetUsesAcc() function to allow binary operators to
7644 fetch their operands in the correct order; made genMinus() emit
7645 compact code for X = LITERAL - Y
7647 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7648 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7649 sprintf() in line 1267.
7651 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7652 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7655 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7656 Changes to aslink (All the changes are marked with 'JCF'):
7658 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7661 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7662 area BSEG. Also moves, if possible, the DATA area down into the internal
7663 ram so more space is available.
7665 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7668 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7669 not bytes. Function summary() which creates a memory usage summary
7670 file with extension .mem. Reports of overlaping stack and small stack
7671 size. If the space for the stack is less than 16 bytes aslink trows a
7674 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7675 the 8051. Option 'y' for memory summary output file.
7677 Changes to sdcc (All the changes are marked with 'JCF'):
7679 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7681 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7682 overlaying area for it (uses RegBankUsed[4]).
7684 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7685 bank zero as used by default. By default aslink locates the stack
7686 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7687 the creation of the .mem file. Delegates the allocation of data area
7688 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7689 the begining of the stack area to aslink.
7691 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7692 glue() in SDCCglue.c creates an area for it.
7694 2002-09-03 Borut Razem <borut.razem AT siol.net>
7695 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7696 sdcc/src/pic/glue.c:
7697 introduced atexit() handler for teporay files removal in case of
7698 errors, assertions, ...
7700 2002-08-29 Borut Razem <borut.razem AT siol.net>
7701 * sdcc/support/cpp2/auto-host_vc_in.h:
7702 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7703 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7704 Maybe there is a similar problem with BORLANDC? It should be checked!
7706 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7707 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7708 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7709 was not executed, and the compiler (cl) launched a warning:
7710 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7712 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7713 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7715 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7716 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7718 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7719 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7720 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7721 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7722 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7723 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7724 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7725 - added Release configuration in VS projects
7726 - review of compiler an linker options
7727 - VC .exe files are generated in bin_vc directory, not to interfere
7728 with binaries generated from other projects (cygwin, mingw, bcc ...)
7730 * sdcc/src/yacc.dsp: added
7732 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7733 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7734 and insert the version number definitions from .version
7736 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7738 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7739 added - genarate auto-host.h using auto-host_vc_in.h as template
7742 removed from CVS, generated automatically
7744 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7745 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7747 2002-08-11 Borut Razem <borut.razem AT siol.net>
7748 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7750 2002-08-10 Borut Razem <borut.razem AT siol.net>
7751 * src/SDCCmain.c (main):
7752 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7753 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7754 The consequence was that some temporary files were not removed.
7757 unification of code in functions tempfilename() and tempfile():
7758 function tempnam() is defined in Visual Studio 6.0 and .NET
7760 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7762 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7763 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7764 - removed compiler command line option /WX: Treats all warnings as errors
7765 - update a list of source files, included into the project
7767 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7768 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7769 changed project type to Generic Project so that can be correcly converted to VS.NET project
7771 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7773 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7775 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7777 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7778 added return 0 statements after assert() to make compiler happy
7780 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7781 added newline in the def file to keep MSC compiler satisfied
7783 * sdcc/src/z80/gen.c:
7784 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7785 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7786 - solved MSC error in function aopDump()
7788 * sdcc_vc.h: define PREFIX as "\\sdcc"
7790 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7791 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7793 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7794 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7795 - Rewrote the register banking algorithm.
7796 - Added pCode live-range analysis to registers (for now, only non-used and
7797 singly-used registers optimized away)
7799 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7801 * 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.
7803 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7804 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7806 2002-04-22 Michael Hope <michaelh AT vroom>

7822 * src/z80/peeph.def: Added transpose redundent load rule.
7824 * src/z80/main.c: Added force callee saves for jaune.
7826 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7828 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7830 2002-03-28 Johan Knol <johan AT balder>
7832 * src/SDCCval.c: fixed bug #532436
7834 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7836 Added "char *Processor" field to the port structure.
7839 Added -p option. Allows port dependent processor to be specified.
7842 Initialized the new field char *Processor field to NULL in all ports
7845 Compiler generated registers for interrupt context saving
7846 were not getting allocated.
7848 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7851 Fixed left shift. Will promote the left side of a left shift
7852 if a) left shifting more than size of operand or b) when assigned
