498 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
499 on rIfx (genCmp was broken)
501 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
503 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
504 * src/z80/main.c (_keywords[]),
505 * src/SDCCglobal.h (struct options),
507 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
508 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
509 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
510 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
511 always available in leading double underscore form. The C99 support is
512 mostly missing, but it's a start.
513 * support/regression/tests/bug-227710.c: fixed nonconforming use of
514 reserved identifier "__data".

562 2005-03-20 Borut Razem <borut.razem AT siol.net>
564 * support/scripts/inc2h.pl: WIN32 port

590 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
592 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
594 * device/lib/printf_large.c: removed inline assembly for portability and
595 readability. Use printf_fast if speed or size are more important.
596 * src/pic16/gen.c: removed conditions around use of DEBUGpc
597 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
599 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
601 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
602 prevent compiler warning
604 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
606 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
607 moved to level 0 and declared as static. Also they are explicit
608 placed in access bank. This was necessery because some times they
609 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
610 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
611 optimizations. Currently only compare to unsigned char is implemented,
612 * src/pic16/gen.c: added fReturnIdx array,
613 * (struct resolvedIfx) is moved to gen.h and made public,
614 * (struct _G): added sregsAlloc and sregsAllocSet fields,
615 * (aopForSym): added an optimization to directly store in stack of
616 the operand of a SEND iCode,
617 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
618 but as registers instead (AOP_REG) using the fReturnIdx array,
619 * (pic16_freeAsmop): remove the freed register from the
621 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
623 * (pic16_popGetTempRegCond): changed function prototype, now
624 function takes also a bitVector argument v which holds the current
625 set of registers that are allocated for stack access by aopForSym,
626 registers allocated in aopForSym for accessing stack symbols are not
627 any more part of the functions usedRegs field,
628 * (genCall): some times aopOp is called for a stack variable to be
629 send, aopForSym might perform the push, if this is true make sure
630 that genCall doesn't push the variable twice by testing _G.resDirect,
631 * (genFunction): changed testing for unspecified interrupt number
632 from 256 to INTNO_UNSPEC,
633 * modified selection scheme of frame pointer generation. Previously
634 if function did use local registers a frame pointer was generated,
635 now a frame pointer is generated only if function has arguments
636 (that need PLUSW2 register access), or has stack arguments, or the
637 compiler is not instructed to omit the frame pointer,
638 * (genEndFunction): before restoring local registers that were saved
639 in the function preamble, also restore the registers that *might*
640 have been allocated for stack access,
641 * (genRet): removed some old comments,
642 * (genCmp, the active (RN's) version): added a call to the
643 pic16_genCmp_special function to perform the compare with a more
644 robust and optimized way,
645 * (genInline): a feature has been added in inline code generation,
646 which allows a wildcard variable substitution when writing inline
647 assembly. Code is incomplete and experimental therefore undocumented,
648 * (genCast): changed order of aopOp for result and right to allow
649 aopForSym to directly load the result if possible,
650 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
651 perform an optimized compare on some selected special occasions,
652 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
653 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
654 generate an IVT any more,
655 * src/pic16/main.c (pic16_optionsTable): added command line option
657 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
658 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
660 * src/pic16/NOTES: Raphael Neider added in list of active developers
661 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
662 jumptable_end to prevent bug #,
663 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
664 inCond and outCond fields,
665 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
666 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
667 turn off register spilling,
668 * (packRegsForOneUse): synced with other ports' versions although it
669 is not used currently,
670 * (pic16_packRegisters): added an optimization while reading
671 structure bitfields, some registers may be saved (malloc code is
672 decreased by 80 bytes)
674 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
676 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
677 left is a bitfield, if yes, then don't optimize assignment. Perhaps
678 this can be optimized more?
680 2005-03-10 Raphael Neider <rneider AT web.de>
682 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
683 genNearPointerGet): (hopefully) fixed access to bitfields via
684 pointers (p->bitN = x; and x = p->bitN; failed)

863 * src/pic16/main.c (_process_pragma): fixed another malloc bug
864 (sizeof(sectNames) changed to sizeof(sectName))

874 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
875 this might fix SIGSEGVs on MinGW...
876 * src/SDCCopt.c (killDeadCode): restored original behaviour
877 (volatile operands might get thrown away though)
879 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
881 * src/pic16/gen.c: fixed bug #1106975,

1340 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1342 * src/pic16/device.h,
1343 * src/pic16/genarith.c,
1346 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1348 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1350 Large cummulative patch for pic16 port.
1351 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1352 to call when a stack overflow occurs,
1353 * (malloc.h): added CVS Id tag,
1354 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1356 * added libc directory. The current version of LibC contains string
1357 functions, ctype functions and macros and some functions of the
1358 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1359 be extensively tested in the future. Standard disclaimer here.
1360 Library is not automatically build yet. But one can build it by
1361 invoking 'make' inside the libc directory.
1362 * added ADC library under libio. Preliminary version yet.
1364 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1365 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1366 aopForRemat() now and not by pic16_aopOp(),
1367 * (pic16_popGetTempReg): removed warning messgae when allocating
1368 temporary registers, its a buggy feature and will be removed,
1369 * (pic16_popGet): set register instance field in AOP_CRY,
1370 * (pic16_outBitC): fixed for results in size greater than 1,
1371 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1372 * (pic16_storeForReturn): optimized return of 0,
1373 * (genCmp): experimental code for new genCmp which uses PIC18's
1374 special compare&skip instructions. Initial tests fail some times
1375 with variables grater than 1 byte in size, so new code is disabled,
1376 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1378 * (genCast): began a fix to optimize the casting of a bit to another
1379 bit, now assigning a bitfield to another bitfield will fail, sorry,
1380 * src/pic16/main.c: disabled the use of lr-support feature,
1381 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1382 * added some function prototypes, added function _debugf prototype,
1383 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1384 bits with offset (case PO_GPR_BIT),
1385 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1387 * (isBankInstruction): modified to return 0 for no banking instruction,
1388 and 1 for banking instruction,
1389 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1390 caused stop processing pCodes after a inline assembly block,
1391 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1392 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1393 registers when it shouldn't,
1394 * src/pic16/ralloc.c (allocReg): add preliminary support for
1395 supporting a limited set of temporary registers,
1397 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1399 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1400 genDataPointerSet): ensure assignments always copy in MSB to LSB
1402 (loadRegFromAop): recognize CLRH optimization,
1403 (genFunction): optimize RECEIVE iCodes in reentrant functions
1405 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1407 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1408 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1410 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
1411 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
1412 contiguous with data
1414 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1416 * device/lib/_gptrget.c (_gptrget),
1417 * device/lib/_gptrgetc.c (_gptrgetc),
1418 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1419 instead of sjmp to ret
1420 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1421 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1423 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4402 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4404 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4405 loaded with the linker search paths (-L arguments) and the libraries
4406 to be linked with the current source (-l arguments). Changes
4407 currently will affect only the pic16 port.
4408 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4409 include path the port specific paths and port specific libraries,
4410 * gplink command now contains the $3 argument,
4411 * src/pic16/device.h,
4412 * src/pic16/device.c,: structure PIC_device is made public and
4413 renamed to PIC16_device, the same for variable Pics which is renamed

4428 Documenting changes from previous commits.
4429 * configure.in (version 1.56),
4430 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4431 when generating output files to configure the pic16 library,
4432 but now I've commented it out, since gputils aren't installed in the
4433 SF compile farm, so library won't compile
4435 * device/lib/Makefile.in (version 1.56): initially I've added in
4436 target 'all' the prerequestive 'model-pic16' so it compiled the
4437 pic16 library, but now I've commented it out for the same reasons
4439 * added targets 'model-pic16' and 'objects-pic16' to compile the
4441 * added target 'port-specific-objects-pic16' to handle the
4442 generated libraries and copy them into the build/ directory
4443 * added target 'clean-intermediate-pic16' to clean intermediate
4444 files into pic16 directory
4445 * in target 'installdirs' added line to create directory pic16 in

4466 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4467 option so that it actually works. Made it specific to the z80, since
4468 the gbz80 doesn't have these kinds of I/O ports.
4470 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4472 * device/include/z180.h,

4496 via literal number. The symbol is placed in the corresponding
4497 position of the data ram
4498 * (pic16_dump_section): relocatable and absolute uninitialized
4499 data are now emitted in sorted order to reduce section naming,
4500 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4501 weren't marked as being in the access bank,
4503 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4505 Added portion of GNU PIC Library under the directory
4506 device/include/pic16 and device/lib/pic16. These files
4507 contain the declarations of SFRs for the PIC18Fxx2 devices.
4508 The directory is initialized via configure from toplevel.
4510 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4512 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4513 the spilllocations to be compared correctly

4537 * doc/sdccman.lyx: Moved and added some sections, small changes
4538 all over. Telling LaTeX to be less strict with word spacing
4539 to better keep the right margin. Changed some notes about
4540 maintainance of the ports in section 3.2.1 - is it OK like this?
4542 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4580 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4582 * src/pic16/peeph.def: all peepholes with movff are commented out,
4583 because there is a problem in the pcode peep optimizer,
4584 * src/pic16/ralloc.c: the register allocator can now reuse local

4586 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4588 Added file src/pic16/NOTES with information about program writing on
4589 the current port version.

4618 gen51Code): more efficient parameter receive for --model-large
4621 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4624 * src/z80/main.c: added missed needLinkerScript flags (more than
4625 one port structure defined in these file)
4626 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4644 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4645 * src/pic/glue.c: added variable udata_section_name to
4646 override default uninitialized data segment definition for
4647 devices only with SHAREBANK memory (reported from Erik Epetrich)
4648 * (pic14emitOverlay): modified to emit a commented overlay segment
4649 directive when no overlay data exist
4650 * (picglue): modified to emit uninitialized data segment
4651 according to udata_section_name

4661 2004-01-07 Borut Razem <borut.razem AT siol.net>
4663 * support/scripts/sdcc.nsi: update PATH
4664 * support/scripts/sdcc.ico: craeted

4671 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4673 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4675 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4677 include information about variables allocated to the overlay
4680 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4682 * as/mcs51/lkmain.c: Help about -Y option

4694 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4696 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4697 (default behaviour).
4699 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4701 A python script to validate compiler diagnostic messages. It can be
4702 used to verify that sdcc complains about bad c source code and
4703 gives a good location of the error.
4704 * support/valdiag/Makefile,
4705 * support/valdiag/valdiag.py,
4706 * support/valdiag/tests/*
4708 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4710 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4721 * src/common.h: added ifndef/define/endif macros
4722 around the header file.
4723 Bug reported from Jesus Calvino-Fraga
4725 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4727 * sdcc.spec: updated
4728 * device/include/Makefile.in: don't install CVS directories
4729 * device/lib/Makefile.in: added removal of CVS directories after install
4730 * doc/Makefile: fixed install, added local_icons
4731 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4732 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4733 * src/ds390/gen.c (genRightShift): fixed bug #870788
4734 * src/SDCCast.c (decorateType): fixed bug #870781
4736 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4738 PIC16 port related changes:
4739 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4740 added variable stackPos,
4742 * gen.c: genCall, assignResultValue: added support for
4743 pushing/retrieving function parameters to/from stack,
4744 genFunction,genEndFunction: setup stack frame for the
4746 genAddrOf: will be changed according to bug 863624
4748 * added files genutils.c and genutils.h which contain gen*
4749 debugged and optimised functions extracted from gen.c
4751 * glue.c: added variable 'externs' which holds extern symbols,
4752 pic16emitRegularMap: is modified to properly handle relocatable
4753 symbols under the new scheme,
4754 pic16createInterruptVect: is modified
4755 pic16printPublics: is modified to emit 'global' assembler directives,
4756 added pic16_printExterns to print extern symbols,
4757 pic16glue: initializes stack/frame pointer in the beginning of
4758 the assembly output. Temporary hack, will be corrected later,
4759 because gplink yet does not support stack and SDCC does not
4760 yet support a type of crt0.o object to create the final binary.
4762 * Removed many lines that contain 8051 legacy code.
4763 * The code is finally placed under a 'code' directive.
4764 * Added port specific options.
4766 * _process_pragma: simplified since now we do not need *special*
4767 include file to define SFR registers. But a separate header
4768 will be needed. This will be developed later.
4769 * _pic16_parseOptions: added, parses port specific options:
4770 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4771 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4772 --preplace-udata-with=
4774 * _pic16_setDefaultOptions: modified to initialize section names,
4775 but hack is temporarly out of order since it needs improvement.
4776 * _pic16_genAssemblerPreamble: configuration words are emitted by
4777 their address instead of their name. This part is incomplete and
4778 supports only the 18Fxx2 devices. Other devices will emit an error
4779 during assembly since they do not contain the same set of config
4781 * _pic16_genIVT: is modified,
4783 * pcode.c: added definitions for some hardware registers that are needed
4785 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4786 All PCI entries are updated. Now LFSR is supported.
4787 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4788 * added pic16_newpCodeOpLit2 to support instructions with
4789 two literal arguments
4790 * pic16_pCode2str: corrected code that emits assembler instructions
4791 with two literal operands and those that have an access bit modifier
4792 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4793 this fixes a bug which caused some labels to be lost, when an
4794 assembler directive was added, i.e. banksel,
4795 * pic16_FixRegisterBanking: improved logic that causes the insertion
4797 * InlineFunction: functions that are called once, are not any more
4798 inlined. This can be a port option in the future,
4800 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4802 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4803 hold the corresponding uninitialized symbols,
4804 * pic16_allocProcessorRegister: registers have explicit marked the
4806 * pic16_allocInternalRegister: registers are explicit marked as
4808 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4809 processing list, so bit registers were lost,
4812 * ralloc.h: added field 'accessBank' and original symbol operand
4813 in register definition,
4814 * removed the field isMapped from register definition,
4816 ** Several functions have been removed from various sources:
4817 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4818 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4819 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4820 pic16_assignRelocatableRegisters
4822 ** others have been introduced:
4823 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4824 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4826 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4828 * support/scripts/inc2h.pl: changed definition of BIT_AT
4829 to emit 'sbit at' instead of 'bit at'. This was a request.
4831 PIC16 port related preliminary changes:
4832 * gen.c: prefixed function popRegFromString with
4833 pic16_ and all references to it corrected
4834 * pcode.c: all pic16_pc_* hardware registers prefixed
4835 with underscore (_),
4836 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4837 * ralloc.c: newReg(): when register is REG_SFR then
4838 set address to rIdx,
4839 pic16_allocProcessorRegister(): marks register wasUsed=0
4840 pic16_writeUsedRegs(): added a call to assign processor
4841 registers via pic16_assignFixedRegisters
4843 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4845 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4846 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4847 variables in unused register banks. Also the SSEG is placed
4848 wherever there is enough space for it, and IDATA can be anywhere
4849 in internal RAM. For now compile using -Wl-Y[stack_size].
4850 The mem file is different for this option as well, since it
4851 makes no sense of talking about DSEG lenght.
4853 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4855 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4856 in certain cases, e.g. when ROM assignment, patch provided
4857 from Albert den Haan.
4859 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5412 not occur if the control variable is involved with a
5413 relational operator.

5902 A few small changes that speed up the peephole optimizer.
5906 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5908 Try to make the peephole optimizer smarter by maintaining
5909 an association between the assembly source code and the
5910 iCodes that originated them. Put this information to use
5911 with a new peephole rule condition "notVolatile" so that
5912 the rules can be aggressive yet still safe.
5917 * src/mcs51/peeph.def
5919 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5929 Changed the type of the result of the ! (NOT) operator to char;
5930 previously it returned the same type as the source. This allows
5931 us to eliminate all the genFloatNot functions (all of its target
5932 implementations were very buggy) since !float can use the same

5944 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5945 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5946 during interrupts. Ensure WSAVE is located at a shared bank address.
5947 2. Fixed page selection in some places
5948 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5949 the registers name strings.
5950 4. Fixed "signed / unsigned compare" compiler warnings.
5951 5. The PIC port manages its own allocation of the general purpose
5952 registers, but makes no attempt to reuse them. As a result when
5953 compiling it soon runs out of general purpose registers. Some
5954 additional code was added to the files pcode.c and device.c to walk
5955 through the function call tree and rename the registers so that they
5965 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5972 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5974 Made bitfield a distinct type from bit so that bitfields
5975 convert as per ANSI C and bits retain their traditional
5976 boolean style behaviour. Implemented bitfield support in
5984 * src/ds390/gen.c: bit v bitfield split
5985 * src/z80/gen.c: New support for bitfields

5989 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5991 Rules 246.x, 247.x relate to bitfields, the others speed up
5992 access to xdata mapped I/O devices.
5994 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5996 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5998 Cleaned up genPackBits and genUnpackBits and added two helper
5999 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6000 for literal assignments in genPackBits (thanks to Frieder for
6006 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6008 Fixed bug #748310 (pointer to function type mishandled when the
6009 function name is omitted). Also fixed a SIGSEGV when a function
6010 attribute (reentrant, etc) is used on a non-function or on a
6011 function but misplaced before the parameter list.

6040 Made the constant following the "interrupt" keyword optional. If
6041 omitted, the function will not automatically be given an entry
6042 in the interrupt vector table (similar to #pragma NOIV, but
6043 less syntacticly kludgy). The interrupt number is also now
6044 range checked. Also fixed a bug in the high order bit example

6520 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6521 the regression tests I'm not brave enough to enable 245.b, 245.c
6522 * doc/sdccman.lyx: added latex preamble for hyperref package.
6523 Using pdflatex this will give you a hyperlinked pdf file with

6565 it can be defined with CFLAGS when running configure
6566 * src/SDCCmain.c: fixed compiling + linking with object files
6568 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6570 * configure.in: configure for pic16 port,
6571 added --disable-pic16-port
6572 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6573 * src/SDCCmain.c: linkOptions is changed to set *,
6574 added if/endif conditional macros to remove options help
6575 messages from optionsTable when a port is not configured, added
6576 support for the PIc16 port in the ports table, when executing
6577 the compiler with no port specified on command line, a default
6578 port is selected with the new macro DEFAULT_PORT which is
6579 defined in port.h, in setDefaultOptions() linkOptions is removed
6580 from initialization assignment, since now it is a set,
6581 parseCmdLine uses setParseWithComma for linkOptions, in
6582 linkEdit() linkOptions are accessed with new function indexSet()
6583 which returns the i'th item of a set variable. See SDCCset.c, in
6584 linkEdit() when calling buildCmdLine(), added linkOptions as
6585 last argument. Now users can pass arguments to gplink via the
6586 -Wl option, main() uses pic16glue() to glue up pic16 programs
6587 * src/SDCCpeeph.c: various changes to support pic16

6598 * src/pic16/glue.c: commented out some error producing lines
6599 * src/pic16/main.c: __config directives are commented out to stop
6600 gpasm complaining and test the linkage with gplink, _linkCmd and
6601 _asmCmd changed to be more gplink and gpasm friendly
6602 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6603 produced an error when parsed, peep rule 12 is added to utilize
6604 movff, but it is commented out since the pCode does not support
6605 yet a command with 2 address arguments
6607 2003-05-18 <johan AT balder>
6609 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6634 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6636 2003-05-11 Borut Razem <borut.razem AT siol.net>
6638 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6639 the path of bin directory, so that PATH is the only env. variable, which has to be set
6640 in case of standard installation.
6641 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7644 * src/SDCCicode.c: fixed array add
7646 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7647 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7648 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7650 2003-01-04 <johan AT balder>
7652 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7654 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7667 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7668 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7670 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7672 * in \sdcc\as\mcs51\ changed these files in order to create an
7673 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7674 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7675 following files to include the previous two files: aslink.dsp,
7676 Makefile.aslink, Makefile.bcc, and Makefile.in.
7678 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7679 .adb instead of .cdb
7681 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7683 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7684 value from option --iram-size.
7686 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7688 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7691 2002-09-18 <wiml AT hhhh.org>
7693 * SDCClrange.h: exposed setFromRange() and setToRange()
7694 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7695 packRegsForAccUse() (bug 542397)
7696 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7697 multiple times and emitting the fetch operations more than once
7698 added aopGetUsesAcc() function to allow binary operators to
7699 fetch their operands in the correct order; made genMinus() emit
7700 compact code for X = LITERAL - Y
7702 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7703 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7704 sprintf() in line 1267.
7706 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7707 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7710 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7711 Changes to aslink (All the changes are marked with 'JCF'):
7713 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7716 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7717 area BSEG. Also moves, if possible, the DATA area down into the internal
7718 ram so more space is available.
7720 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7723 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7724 not bytes. Function summary() which creates a memory usage summary
7725 file with extension .mem. Reports of overlaping stack and small stack
7726 size. If the space for the stack is less than 16 bytes aslink trows a
7729 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7730 the 8051. Option 'y' for memory summary output file.
7732 Changes to sdcc (All the changes are marked with 'JCF'):
7734 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7736 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7737 overlaying area for it (uses RegBankUsed[4]).
7739 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7740 bank zero as used by default. By default aslink locates the stack
7741 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7742 the creation of the .mem file. Delegates the allocation of data area
7743 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7744 the begining of the stack area to aslink.
7746 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7747 glue() in SDCCglue.c creates an area for it.
7749 2002-09-03 Borut Razem <borut.razem AT siol.net>
7750 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7751 sdcc/src/pic/glue.c:
7752 introduced atexit() handler for teporay files removal in case of
7753 errors, assertions, ...
7755 2002-08-29 Borut Razem <borut.razem AT siol.net>
7756 * sdcc/support/cpp2/auto-host_vc_in.h:
7757 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7758 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7759 Maybe there is a similar problem with BORLANDC? It should be checked!
7761 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7762 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7763 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7764 was not executed, and the compiler (cl) launched a warning:
7765 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7767 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7768 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7770 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7771 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7773 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7774 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

7776 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7777 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7778 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7779 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7780 - added Release configuration in VS projects
7781 - review of compiler an linker options
7782 - VC .exe files are generated in bin_vc directory, not to interfere
7783 with binaries generated from other projects (cygwin, mingw, bcc ...)
7785 * sdcc/src/yacc.dsp: added
7787 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7788 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7789 and insert the version number definitions from .version
7791 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7793 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7794 added - genarate auto-host.h using auto-host_vc_in.h as template
7797 removed from CVS, generated automatically
7799 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7800 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7802 2002-08-11 Borut Razem <borut.razem AT siol.net>
7803 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7805 2002-08-10 Borut Razem <borut.razem AT siol.net>
7806 * src/SDCCmain.c (main):
7807 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7808 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7809 The consequence was that some temporary files were not removed.
7812 unification of code in functions tempfilename() and tempfile():
7813 function tempnam() is defined in Visual Studio 6.0 and .NET
7815 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7817 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7818 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7819 - removed compiler command line option /WX: Treats all warnings as errors
7820 - update a list of source files, included into the project
7822 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7823 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
