444 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
445 * src/z80/main.c (_keywords[]),
446 * src/SDCCglobal.h (struct options),
448 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
449 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
450 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
451 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
452 always available in leading double underscore form. The C99 support is
453 mostly missing, but it's a start.
454 * support/regression/tests/bug-227710.c: fixed nonconforming use of
455 reserved identifier "__data".
457 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
459 * src/mcs51/peeph.def: fixed bug 1170013

465 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
467 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
470 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
472 * src/port.h (struct PORT),

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

511 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
513 * device/include/stdint.h: added
514 * device/lib/abs.c: added
515 * device/lib/labs.c: added
516 * device/include/stdlib.h: added abs() and labs() prototypes

525 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
528 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
530 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
531 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
533 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
535 * device/lib/printf_large.c: removed inline assembly for portability and
536 readability. Use printf_fast if speed or size are more important.
537 * src/pic16/gen.c: removed conditions around use of DEBUGpc
538 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
540 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
542 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
543 prevent compiler warning
545 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
547 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
548 moved to level 0 and declared as static. Also they are explicit
549 placed in access bank. This was necessery because some times they
550 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
551 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
552 optimizations. Currently only compare to unsigned char is implemented,
553 * src/pic16/gen.c: added fReturnIdx array,
554 * (struct resolvedIfx) is moved to gen.h and made public,
555 * (struct _G): added sregsAlloc and sregsAllocSet fields,
556 * (aopForSym): added an optimization to directly store in stack of
557 the operand of a SEND iCode,
558 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
559 but as registers instead (AOP_REG) using the fReturnIdx array,
560 * (pic16_freeAsmop): remove the freed register from the
562 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
564 * (pic16_popGetTempRegCond): changed function prototype, now
565 function takes also a bitVector argument v which holds the current
566 set of registers that are allocated for stack access by aopForSym,
567 registers allocated in aopForSym for accessing stack symbols are not
568 any more part of the functions usedRegs field,
569 * (genCall): some times aopOp is called for a stack variable to be
570 send, aopForSym might perform the push, if this is true make sure
571 that genCall doesn't push the variable twice by testing _G.resDirect,
572 * (genFunction): changed testing for unspecified interrupt number
573 from 256 to INTNO_UNSPEC,
574 * modified selection scheme of frame pointer generation. Previously
575 if function did use local registers a frame pointer was generated,
576 now a frame pointer is generated only if function has arguments
577 (that need PLUSW2 register access), or has stack arguments, or the
578 compiler is not instructed to omit the frame pointer,
579 * (genEndFunction): before restoring local registers that were saved
580 in the function preamble, also restore the registers that *might*
581 have been allocated for stack access,
582 * (genRet): removed some old comments,
583 * (genCmp, the active (RN's) version): added a call to the
584 pic16_genCmp_special function to perform the compare with a more
585 robust and optimized way,
586 * (genInline): a feature has been added in inline code generation,
587 which allows a wildcard variable substitution when writing inline
588 assembly. Code is incomplete and experimental therefore undocumented,
589 * (genCast): changed order of aopOp for result and right to allow
590 aopForSym to directly load the result if possible,
591 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
592 perform an optimized compare on some selected special occasions,
593 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
594 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
595 generate an IVT any more,
596 * src/pic16/main.c (pic16_optionsTable): added command line option
598 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
599 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
601 * src/pic16/NOTES: Raphael Neider added in list of active developers
602 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
603 jumptable_end to prevent bug #,
604 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
605 inCond and outCond fields,
606 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
607 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
608 turn off register spilling,
609 * (packRegsForOneUse): synced with other ports' versions although it
610 is not used currently,
611 * (pic16_packRegisters): added an optimization while reading
612 structure bitfields, some registers may be saved (malloc code is
613 decreased by 80 bytes)
615 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
617 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
618 left is a bitfield, if yes, then don't optimize assignment. Perhaps
619 this can be optimized more?
621 2005-03-10 Raphael Neider <rneider AT web.de>
623 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
624 genNearPointerGet): (hopefully) fixed access to bitfields via
625 pointers (p->bitN = x; and x = p->bitN; failed)

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

908 copy the third byte from the int -- now assumes 0x80 (data memory)
909 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
910 operands (genAddLit expects the iCode's operands to swapped as

1297 * added libc directory. The current version of LibC contains string
1298 functions, ctype functions and macros and some functions of the
1299 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1300 be extensively tested in the future. Standard disclaimer here.

1313 * (pic16_storeForReturn): optimized return of 0,
1314 * (genCmp): experimental code for new genCmp which uses PIC18's
1315 special compare&skip instructions. Initial tests fail some times
1316 with variables grater than 1 byte in size, so new code is disabled,
1317 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1319 * (genCast): began a fix to optimize the casting of a bit to another
1320 bit, now assigning a bitfield to another bitfield will fail, sorry,

1329 and 1 for banking instruction,
1330 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1331 caused stop processing pCodes after a inline assembly block,

1334 registers when it shouldn't,
1335 * src/pic16/ralloc.c (allocReg): add preliminary support for
1336 supporting a limited set of temporary registers,
1338 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4343 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4345 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4346 loaded with the linker search paths (-L arguments) and the libraries
4347 to be linked with the current source (-l arguments). Changes
4348 currently will affect only the pic16 port.
4349 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4350 include path the port specific paths and port specific libraries,
4351 * gplink command now contains the $3 argument,
4352 * src/pic16/device.h,
4353 * src/pic16/device.c,: structure PIC_device is made public and
4354 renamed to PIC16_device, the same for variable Pics which is renamed

4369 Documenting changes from previous commits.
4370 * configure.in (version 1.56),
4371 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4372 when generating output files to configure the pic16 library,
4373 but now I've commented it out, since gputils aren't installed in the
4374 SF compile farm, so library won't compile
4376 * device/lib/Makefile.in (version 1.56): initially I've added in
4377 target 'all' the prerequestive 'model-pic16' so it compiled the
4378 pic16 library, but now I've commented it out for the same reasons
4380 * added targets 'model-pic16' and 'objects-pic16' to compile the
4382 * added target 'port-specific-objects-pic16' to handle the
4383 generated libraries and copy them into the build/ directory
4384 * added target 'clean-intermediate-pic16' to clean intermediate
4385 files into pic16 directory
4386 * in target 'installdirs' added line to create directory pic16 in
4387 the installation path
4389 * device/include/Makefile.in (version 1.11): in target 'install'
4390 added lines to copy all header files to installation path,
4391 * in target 'installdirs' added line create directory for pic16
4392 headers in the installation path

4407 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4408 option so that it actually works. Made it specific to the z80, since
4409 the gbz80 doesn't have these kinds of I/O ports.
4411 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4413 * device/include/z180.h,

4435 Mainly changes to support compilation of the device libraries
4436 * src/pic16/device.c: stack is allocated via symbol and not
4437 via literal number. The symbol is placed in the corresponding
4438 position of the data ram
4439 * (pic16_dump_section): relocatable and absolute uninitialized
4440 data are now emitted in sorted order to reduce section naming,
4441 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4442 weren't marked as being in the access bank,
4444 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4446 Added portion of GNU PIC Library under the directory
4447 device/include/pic16 and device/lib/pic16. These files
4448 contain the declarations of SFRs for the PIC18Fxx2 devices.
4449 The directory is initialized via configure from toplevel.
4451 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4478 * doc/sdccman.lyx: Moved and added some sections, small changes
4479 all over. Telling LaTeX to be less strict with word spacing
4480 to better keep the right margin. Changed some notes about
4481 maintainance of the ports in section 3.2.1 - is it OK like this?
4483 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4618 include information about variables allocated to the overlay
4621 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4623 * as/mcs51/lkmain.c: Help about -Y option

4635 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4637 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4638 (default behaviour).
4640 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4642 A python script to validate compiler diagnostic messages. It can be
4643 used to verify that sdcc complains about bad c source code and
4644 gives a good location of the error.
4645 * support/valdiag/Makefile,
4646 * support/valdiag/valdiag.py,
4647 * support/valdiag/tests/*
4649 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4651 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4662 * src/common.h: added ifndef/define/endif macros
4663 around the header file.
4664 Bug reported from Jesus Calvino-Fraga
4666 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4668 * sdcc.spec: updated
4669 * device/include/Makefile.in: don't install CVS directories
4670 * device/lib/Makefile.in: added removal of CVS directories after install
4671 * doc/Makefile: fixed install, added local_icons
4672 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4673 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4674 * src/ds390/gen.c (genRightShift): fixed bug #870788
4675 * src/SDCCast.c (decorateType): fixed bug #870781
4677 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4679 PIC16 port related changes:
4680 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4681 added variable stackPos,
4683 * gen.c: genCall, assignResultValue: added support for
4684 pushing/retrieving function parameters to/from stack,
4685 genFunction,genEndFunction: setup stack frame for the
4687 genAddrOf: will be changed according to bug 863624
4689 * added files genutils.c and genutils.h which contain gen*
4690 debugged and optimised functions extracted from gen.c
4692 * glue.c: added variable 'externs' which holds extern symbols,
4693 pic16emitRegularMap: is modified to properly handle relocatable
4694 symbols under the new scheme,
4695 pic16createInterruptVect: is modified
4696 pic16printPublics: is modified to emit 'global' assembler directives,
4697 added pic16_printExterns to print extern symbols,
4698 pic16glue: initializes stack/frame pointer in the beginning of
4699 the assembly output. Temporary hack, will be corrected later,
4700 because gplink yet does not support stack and SDCC does not
4701 yet support a type of crt0.o object to create the final binary.
4703 * Removed many lines that contain 8051 legacy code.
4704 * The code is finally placed under a 'code' directive.
4705 * Added port specific options.
4707 * _process_pragma: simplified since now we do not need *special*
4708 include file to define SFR registers. But a separate header
4709 will be needed. This will be developed later.
4710 * _pic16_parseOptions: added, parses port specific options:
4711 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4712 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4713 --preplace-udata-with=
4715 * _pic16_setDefaultOptions: modified to initialize section names,
4716 but hack is temporarly out of order since it needs improvement.
4717 * _pic16_genAssemblerPreamble: configuration words are emitted by
4718 their address instead of their name. This part is incomplete and
4719 supports only the 18Fxx2 devices. Other devices will emit an error
4720 during assembly since they do not contain the same set of config
4722 * _pic16_genIVT: is modified,
4724 * pcode.c: added definitions for some hardware registers that are needed
4726 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4727 All PCI entries are updated. Now LFSR is supported.
4728 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4729 * added pic16_newpCodeOpLit2 to support instructions with
4730 two literal arguments
4731 * pic16_pCode2str: corrected code that emits assembler instructions
4732 with two literal operands and those that have an access bit modifier
4733 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4734 this fixes a bug which caused some labels to be lost, when an
4735 assembler directive was added, i.e. banksel,
4736 * pic16_FixRegisterBanking: improved logic that causes the insertion
4738 * InlineFunction: functions that are called once, are not any more
4739 inlined. This can be a port option in the future,
4741 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4743 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4744 hold the corresponding uninitialized symbols,
4745 * pic16_allocProcessorRegister: registers have explicit marked the
4747 * pic16_allocInternalRegister: registers are explicit marked as
4749 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4750 processing list, so bit registers were lost,
4753 * ralloc.h: added field 'accessBank' and original symbol operand
4754 in register definition,
4755 * removed the field isMapped from register definition,
4757 ** Several functions have been removed from various sources:
4758 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4759 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4760 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4761 pic16_assignRelocatableRegisters
4763 ** others have been introduced:
4764 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4765 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4767 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4769 * support/scripts/inc2h.pl: changed definition of BIT_AT
4770 to emit 'sbit at' instead of 'bit at'. This was a request.
4772 PIC16 port related preliminary changes:
4773 * gen.c: prefixed function popRegFromString with
4774 pic16_ and all references to it corrected
4775 * pcode.c: all pic16_pc_* hardware registers prefixed
4776 with underscore (_),
4777 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4778 * ralloc.c: newReg(): when register is REG_SFR then
4779 set address to rIdx,
4780 pic16_allocProcessorRegister(): marks register wasUsed=0
4781 pic16_writeUsedRegs(): added a call to assign processor
4782 registers via pic16_assignFixedRegisters
4784 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4786 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4787 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4788 variables in unused register banks. Also the SSEG is placed
4789 wherever there is enough space for it, and IDATA can be anywhere
4790 in internal RAM. For now compile using -Wl-Y[stack_size].
4791 The mem file is different for this option as well, since it
4792 makes no sense of talking about DSEG lenght.
4794 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4796 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4797 in certain cases, e.g. when ROM assignment, patch provided
4798 from Albert den Haan.
4800 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5823 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5824 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5825 type for bits was changed. It resulted in bit variables becoming

5843 A few small changes that speed up the peephole optimizer.
5847 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5849 Try to make the peephole optimizer smarter by maintaining
5850 an association between the assembly source code and the
5851 iCodes that originated them. Put this information to use
5852 with a new peephole rule condition "notVolatile" so that
5853 the rules can be aggressive yet still safe.
5858 * src/mcs51/peeph.def
5860 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5864 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5865 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5866 if the left or right operand symbols have the accuse flag set.
5868 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5870 Changed the type of the result of the ! (NOT) operator to char;
5871 previously it returned the same type as the source. This allows
5872 us to eliminate all the genFloatNot functions (all of its target
5873 implementations were very buggy) since !float can use the same
5876 * src/SDCCicode.c (ast2iCode): ! returns char

5885 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5886 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5887 during interrupts. Ensure WSAVE is located at a shared bank address.
5888 2. Fixed page selection in some places
5889 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5890 the registers name strings.
5891 4. Fixed "signed / unsigned compare" compiler warnings.
5892 5. The PIC port manages its own allocation of the general purpose
5893 registers, but makes no attempt to reuse them. As a result when
5894 compiling it soon runs out of general purpose registers. Some
5895 additional code was added to the files pcode.c and device.c to walk
5896 through the function call tree and rename the registers so that they
5906 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5913 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5915 Made bitfield a distinct type from bit so that bitfields
5916 convert as per ANSI C and bits retain their traditional
5917 boolean style behaviour. Implemented bitfield support in
5925 * src/ds390/gen.c: bit v bitfield split
5926 * src/z80/gen.c: New support for bitfields
5927 * support/regression/tests/bitfields.c: reenabled z80,
5930 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5932 Rules 246.x, 247.x relate to bitfields, the others speed up
5933 access to xdata mapped I/O devices.
5935 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5937 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5939 Cleaned up genPackBits and genUnpackBits and added two helper

5949 Fixed bug #748310 (pointer to function type mishandled when the
5950 function name is omitted). Also fixed a SIGSEGV when a function
5951 attribute (reentrant, etc) is used on a non-function or on a
5952 function but misplaced before the parameter list.

5970 * src/SDCC.y: More bitfield related error checking
5972 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
5973 * support/Util/SDCCerr.h,
5974 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
5975 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
5976 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs

5979 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5981 Made the constant following the "interrupt" keyword optional. If
5982 omitted, the function will not automatically be given an entry
5983 in the interrupt vector table (similar to #pragma NOIV, but
5984 less syntacticly kludgy). The interrupt number is also now
5985 range checked. Also fixed a bug in the high order bit example
5992 * support/Util/SDCCerr.c
5993 * support/Util/SDCCerr.h
5996 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6000 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6001 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6003 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6004 be re-activated by defining REDUCE_LITERALS)
6005 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6006 unsigned, but are signed by default
6007 * src/SDCCval.c (constVal): rearranged
6008 * src/SDCCval.c (valMod): preliminary fix
6009 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6052 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6053 * src/SDCCval.c (valDiv, valMod): fixed signdness
6054 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6055 signedness of modulo, left and right shift
6056 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

6516 messages from optionsTable when a port is not configured, added
6517 support for the PIc16 port in the ports table, when executing
6518 the compiler with no port specified on command line, a default
6519 port is selected with the new macro DEFAULT_PORT which is
6520 defined in port.h, in setDefaultOptions() linkOptions is removed
6521 from initialization assignment, since now it is a set,
6522 parseCmdLine uses setParseWithComma for linkOptions, in
6523 linkEdit() linkOptions are accessed with new function indexSet()
6524 which returns the i'th item of a set variable. See SDCCset.c, in
6525 linkEdit() when calling buildCmdLine(), added linkOptions as
6526 last argument. Now users can pass arguments to gplink via the
6527 -Wl option, main() uses pic16glue() to glue up pic16 programs

7589 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7591 2003-01-04 <johan AT balder>
7593 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7595 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7596 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7598 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7599 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7608 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7609 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7611 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7613 * in \sdcc\as\mcs51\ changed these files in order to create an
7614 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7615 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7616 following files to include the previous two files: aslink.dsp,
7617 Makefile.aslink, Makefile.bcc, and Makefile.in.
7619 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7620 .adb instead of .cdb
7622 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7624 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7625 value from option --iram-size.
7627 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7629 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7632 2002-09-18 <wiml AT hhhh.org>
7634 * SDCClrange.h: exposed setFromRange() and setToRange()
7635 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7636 packRegsForAccUse() (bug 542397)
7637 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7638 multiple times and emitting the fetch operations more than once
7639 added aopGetUsesAcc() function to allow binary operators to
7640 fetch their operands in the correct order; made genMinus() emit
7641 compact code for X = LITERAL - Y
7643 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7644 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7645 sprintf() in line 1267.
7647 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7648 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7651 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7652 Changes to aslink (All the changes are marked with 'JCF'):
7654 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7657 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7658 area BSEG. Also moves, if possible, the DATA area down into the internal
7659 ram so more space is available.
7661 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7664 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7665 not bytes. Function summary() which creates a memory usage summary
7666 file with extension .mem. Reports of overlaping stack and small stack
7667 size. If the space for the stack is less than 16 bytes aslink trows a
7670 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7671 the 8051. Option 'y' for memory summary output file.
7673 Changes to sdcc (All the changes are marked with 'JCF'):
7675 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7677 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7678 overlaying area for it (uses RegBankUsed[4]).
7680 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7681 bank zero as used by default. By default aslink locates the stack
7682 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7683 the creation of the .mem file. Delegates the allocation of data area
7684 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7685 the begining of the stack area to aslink.
7687 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7688 glue() in SDCCglue.c creates an area for it.
7690 2002-09-03 Borut Razem <borut.razem AT siol.net>
7691 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7692 sdcc/src/pic/glue.c:
7693 introduced atexit() handler for teporay files removal in case of
7694 errors, assertions, ...
7696 2002-08-29 Borut Razem <borut.razem AT siol.net>
7697 * sdcc/support/cpp2/auto-host_vc_in.h:
7698 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7699 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7700 Maybe there is a similar problem with BORLANDC? It should be checked!
7702 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7703 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7704 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7705 was not executed, and the compiler (cl) launched a warning:
7706 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7708 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7709 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7711 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7712 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7714 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7715 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7716 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7717 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7718 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7719 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7720 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7721 - added Release configuration in VS projects
7722 - review of compiler an linker options
7723 - VC .exe files are generated in bin_vc directory, not to interfere
7724 with binaries generated from other projects (cygwin, mingw, bcc ...)
7726 * sdcc/src/yacc.dsp: added
7728 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7729 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7730 and insert the version number definitions from .version
7732 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7734 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7735 added - genarate auto-host.h using auto-host_vc_in.h as template
7738 removed from CVS, generated automatically
7740 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7741 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7743 2002-08-11 Borut Razem <borut.razem AT siol.net>
7744 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7746 2002-08-10 Borut Razem <borut.razem AT siol.net>
7747 * src/SDCCmain.c (main):
7748 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7749 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7750 The consequence was that some temporary files were not removed.
7753 unification of code in functions tempfilename() and tempfile():
7754 function tempnam() is defined in Visual Studio 6.0 and .NET
7756 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7758 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7759 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7760 - removed compiler command line option /WX: Treats all warnings as errors
7761 - update a list of source files, included into the project
7763 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7764 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7765 changed project type to Generic Project so that can be correcly converted to VS.NET project
7767 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7769 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7771 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7773 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7774 added return 0 statements after assert() to make compiler happy
7776 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7777 added newline in the def file to keep MSC compiler satisfied
7779 * sdcc/src/z80/gen.c:
7780 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7781 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7782 - solved MSC error in function aopDump()
7784 * sdcc_vc.h: define PREFIX as "\\sdcc"
7786 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7787 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7789 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7790 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7791 - Rewrote the register banking algorithm.
7792 - Added pCode live-range analysis to registers (for now, only non-used and
7793 singly-used registers optimized away)
7795 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7797 * 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.
7799 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7800 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7802 2002-04-22 Michael Hope <michaelh AT vroom>

7822 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7824 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7826 2002-03-28 Johan Knol <johan AT balder>
7828 * src/SDCCval.c: fixed bug #532436
7830 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7832 Added "char *Processor" field to the port structure.
7835 Added -p option. Allows port dependent processor to be specified.
7838 Initialized the new field char *Processor field to NULL in all ports
7841 Compiler generated registers for interrupt context saving
7842 were not getting allocated.
7844 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7847 Fixed left shift. Will promote the left side of a left shift
7848 if a) left shifting more than size of operand or b) when assigned
7849 to something size > size of left side
7851 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7853 tons of changes. Register allocation has been
7854 rewritten. Added customization for the various PICs. Flow
7855 analysis is restructured. ...
