540 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
541 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
542 always available in leading double underscore form. The C99 support is
543 mostly missing, but it's a start.
544 * support/regression/tests/bug-227710.c: fixed nonconforming use of
545 reserved identifier "__data".
547 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

623 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
625 * device/lib/printf_large.c: removed inline assembly for portability and
626 readability. Use printf_fast if speed or size are more important.
627 * src/pic16/gen.c: removed conditions around use of DEBUGpc
628 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
630 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
632 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
633 prevent compiler warning
635 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
637 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
638 moved to level 0 and declared as static. Also they are explicit
639 placed in access bank. This was necessery because some times they
640 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
641 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
642 optimizations. Currently only compare to unsigned char is implemented,
643 * src/pic16/gen.c: added fReturnIdx array,
644 * (struct resolvedIfx) is moved to gen.h and made public,
645 * (struct _G): added sregsAlloc and sregsAllocSet fields,
646 * (aopForSym): added an optimization to directly store in stack of
647 the operand of a SEND iCode,
648 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
649 but as registers instead (AOP_REG) using the fReturnIdx array,
650 * (pic16_freeAsmop): remove the freed register from the
652 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
654 * (pic16_popGetTempRegCond): changed function prototype, now
655 function takes also a bitVector argument v which holds the current
656 set of registers that are allocated for stack access by aopForSym,
657 registers allocated in aopForSym for accessing stack symbols are not
658 any more part of the functions usedRegs field,
659 * (genCall): some times aopOp is called for a stack variable to be
660 send, aopForSym might perform the push, if this is true make sure
661 that genCall doesn't push the variable twice by testing _G.resDirect,
662 * (genFunction): changed testing for unspecified interrupt number
663 from 256 to INTNO_UNSPEC,
664 * modified selection scheme of frame pointer generation. Previously
665 if function did use local registers a frame pointer was generated,
666 now a frame pointer is generated only if function has arguments
667 (that need PLUSW2 register access), or has stack arguments, or the
668 compiler is not instructed to omit the frame pointer,
669 * (genEndFunction): before restoring local registers that were saved
670 in the function preamble, also restore the registers that *might*
671 have been allocated for stack access,
672 * (genRet): removed some old comments,
673 * (genCmp, the active (RN's) version): added a call to the
674 pic16_genCmp_special function to perform the compare with a more
675 robust and optimized way,
676 * (genInline): a feature has been added in inline code generation,
677 which allows a wildcard variable substitution when writing inline
678 assembly. Code is incomplete and experimental therefore undocumented,
679 * (genCast): changed order of aopOp for result and right to allow
680 aopForSym to directly load the result if possible,
681 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
682 perform an optimized compare on some selected special occasions,
683 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
684 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
685 generate an IVT any more,
686 * src/pic16/main.c (pic16_optionsTable): added command line option
688 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
689 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
691 * src/pic16/NOTES: Raphael Neider added in list of active developers
692 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
693 jumptable_end to prevent bug #,
694 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
695 inCond and outCond fields,
696 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
697 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
698 turn off register spilling,
699 * (packRegsForOneUse): synced with other ports' versions although it
700 is not used currently,
701 * (pic16_packRegisters): added an optimization while reading
702 structure bitfields, some registers may be saved (malloc code is
703 decreased by 80 bytes)
705 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
707 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
708 left is a bitfield, if yes, then don't optimize assignment. Perhaps
709 this can be optimized more?
711 2005-03-10 Raphael Neider <rneider AT web.de>
713 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
714 genNearPointerGet): (hopefully) fixed access to bitfields via
715 pointers (p->bitN = x; and x = p->bitN; failed)
717 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
719 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

894 * src/pic16/main.c (_process_pragma): fixed another malloc bug
895 (sizeof(sectNames) changed to sizeof(sectName))
896 Both patches fix segfaults under MinGW.

904 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
905 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
906 this might fix SIGSEGVs on MinGW...

1347 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1349 Adding support for replacing ljmps with sjmps in jumptables
1350 generated for switch statements. For now you need to set the
1351 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1352 Now 4 algorithms for mcs51 jumptable generation are used:
1353 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1354 addresses loaded pc-relative for up to 112 cases and stack-pushing
1355 target addresses loaded with offset from dptr for up to 256 cases.
1357 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1358 * src/mcs51/main.c: adapted constants for switch table generation
1359 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1381 Large cummulative patch for pic16 port.
1382 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1383 to call when a stack overflow occurs,
1384 * (malloc.h): added CVS Id tag,
1385 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1387 * added libc directory. The current version of LibC contains string
1388 functions, ctype functions and macros and some functions of the
1389 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1390 be extensively tested in the future. Standard disclaimer here.
1391 Library is not automatically build yet. But one can build it by
1392 invoking 'make' inside the libc directory.
1393 * added ADC library under libio. Preliminary version yet.
1395 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1396 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1397 aopForRemat() now and not by pic16_aopOp(),
1398 * (pic16_popGetTempReg): removed warning messgae when allocating
1399 temporary registers, its a buggy feature and will be removed,
1400 * (pic16_popGet): set register instance field in AOP_CRY,
1401 * (pic16_outBitC): fixed for results in size greater than 1,
1402 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1403 * (pic16_storeForReturn): optimized return of 0,
1404 * (genCmp): experimental code for new genCmp which uses PIC18's
1405 special compare&skip instructions. Initial tests fail some times
1406 with variables grater than 1 byte in size, so new code is disabled,
1407 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1409 * (genCast): began a fix to optimize the casting of a bit to another
1410 bit, now assigning a bitfield to another bitfield will fail, sorry,
1411 * src/pic16/main.c: disabled the use of lr-support feature,
1412 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1413 * added some function prototypes, added function _debugf prototype,
1414 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1415 bits with offset (case PO_GPR_BIT),
1416 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1418 * (isBankInstruction): modified to return 0 for no banking instruction,
1419 and 1 for banking instruction,
1420 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1421 caused stop processing pCodes after a inline assembly block,
1422 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1423 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1424 registers when it shouldn't,
1425 * src/pic16/ralloc.c (allocReg): add preliminary support for
1426 supporting a limited set of temporary registers,
1428 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1430 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1431 genDataPointerSet): ensure assignments always copy in MSB to LSB
1433 (loadRegFromAop): recognize CLRH optimization,
1434 (genFunction): optimize RECEIVE iCodes in reentrant functions
1436 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1438 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1439 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1441 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1447 * device/lib/_gptrget.c (_gptrget),
1448 * device/lib/_gptrgetc.c (_gptrgetc),
1449 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1450 instead of sjmp to ret
1451 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1452 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1454 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4436 loaded with the linker search paths (-L arguments) and the libraries
4437 to be linked with the current source (-l arguments). Changes
4438 currently will affect only the pic16 port.
4439 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4440 include path the port specific paths and port specific libraries,
4441 * gplink command now contains the $3 argument,
4442 * src/pic16/device.h,
4443 * src/pic16/device.c,: structure PIC_device is made public and
4444 renamed to PIC16_device, the same for variable Pics which is renamed
4445 to Pics16. Updated all references to them.
4446 * src/pic16/glue.c (pic16glue): corrected bug with code
4447 initialization which bypassed the variable initializations block.
4449 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4450 COMPILE_FLAGS and added the --nostdinc option
4452 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4454 * device/include/mc68hc908jb8.h: Register defs for another member
4455 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4457 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4459 Documenting changes from previous commits.
4460 * configure.in (version 1.56),
4461 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4462 when generating output files to configure the pic16 library,
4463 but now I've commented it out, since gputils aren't installed in the
4464 SF compile farm, so library won't compile
4466 * device/lib/Makefile.in (version 1.56): initially I've added in
4467 target 'all' the prerequestive 'model-pic16' so it compiled the
4468 pic16 library, but now I've commented it out for the same reasons
4470 * added targets 'model-pic16' and 'objects-pic16' to compile the
4472 * added target 'port-specific-objects-pic16' to handle the
4473 generated libraries and copy them into the build/ directory
4474 * added target 'clean-intermediate-pic16' to clean intermediate
4475 files into pic16 directory
4476 * in target 'installdirs' added line to create directory pic16 in
4477 the installation path
4479 * device/include/Makefile.in (version 1.11): in target 'install'
4480 added lines to copy all header files to installation path,
4481 * in target 'installdirs' added line create directory for pic16
4482 headers in the installation path

4497 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4498 option so that it actually works. Made it specific to the z80, since
4499 the gbz80 doesn't have these kinds of I/O ports.
4501 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4503 * device/include/z180.h,

4516 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4518 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4519 changed interrupt vector table generation to only emit declared vectors.

4525 Mainly changes to support compilation of the device libraries
4526 * src/pic16/device.c: stack is allocated via symbol and not
4527 via literal number. The symbol is placed in the corresponding
4528 position of the data ram
4529 * (pic16_dump_section): relocatable and absolute uninitialized
4530 data are now emitted in sorted order to reduce section naming,
4531 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4532 weren't marked as being in the access bank,
4534 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4536 Added portion of GNU PIC Library under the directory
4537 device/include/pic16 and device/lib/pic16. These files
4538 contain the declarations of SFRs for the PIC18Fxx2 devices.
4539 The directory is initialized via configure from toplevel.
4541 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4543 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4544 the spilllocations to be compared correctly
4546 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4548 * src/SDCCast.c (decorateType): fixed bug introduced today
4550 2004-01-12 Borut Razem <borut.razem AT siol.net>

4568 * doc/sdccman.lyx: Moved and added some sections, small changes
4569 all over. Telling LaTeX to be less strict with word spacing
4570 to better keep the right margin. Changed some notes about
4571 maintainance of the ports in section 3.2.1 - is it OK like this?
4573 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4610 UPPER for immediate operands,
4611 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4613 * src/pic16/peeph.def: all peepholes with movff are commented out,
4614 because there is a problem in the pcode peep optimizer,
4615 * src/pic16/ralloc.c: the register allocator can now reuse local

4617 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4619 Added file src/pic16/NOTES with information about program writing on
4620 the current port version.

4629 * src/SDCCmain.c : fixed #872250: -l command line defined library
4630 files are scanned before standard library files
4632 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4652 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4655 * src/z80/main.c: added missed needLinkerScript flags (more than
4656 one port structure defined in these file)
4657 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4673 needLinkerScript flag
4675 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4676 * src/pic/glue.c: added variable udata_section_name to
4677 override default uninitialized data segment definition for
4678 devices only with SHAREBANK memory (reported from Erik Epetrich)
4679 * (pic14emitOverlay): modified to emit a commented overlay segment
4680 directive when no overlay data exist
4681 * (picglue): modified to emit uninitialized data segment
4682 according to udata_section_name

4687 arguments via -W option
4688 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4689 object file from '.rel' to '.o' in port->linker structure,
4690 changed size of fptr from 2 to 3 in port structure
4692 2004-01-07 Borut Razem <borut.razem AT siol.net>
4694 * support/scripts/sdcc.nsi: update PATH
4695 * support/scripts/sdcc.ico: craeted
4697 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

4700 * doc/Makefile: fix install
4702 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4704 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4706 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4708 include information about variables allocated to the overlay
4711 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4713 * as/mcs51/lkmain.c: Help about -Y option

4725 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4727 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4728 (default behaviour).
4730 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4732 A python script to validate compiler diagnostic messages. It can be
4733 used to verify that sdcc complains about bad c source code and
4734 gives a good location of the error.
4735 * support/valdiag/Makefile,
4736 * support/valdiag/valdiag.py,
4737 * support/valdiag/tests/*
4739 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4752 * src/common.h: added ifndef/define/endif macros
4753 around the header file.
4754 Bug reported from Jesus Calvino-Fraga
4756 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4758 * sdcc.spec: updated
4759 * device/include/Makefile.in: don't install CVS directories
4760 * device/lib/Makefile.in: added removal of CVS directories after install
4761 * doc/Makefile: fixed install, added local_icons
4762 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4763 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4764 * src/ds390/gen.c (genRightShift): fixed bug #870788
4765 * src/SDCCast.c (decorateType): fixed bug #870781
4767 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4769 PIC16 port related changes:
4770 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4771 added variable stackPos,
4773 * gen.c: genCall, assignResultValue: added support for
4774 pushing/retrieving function parameters to/from stack,
4775 genFunction,genEndFunction: setup stack frame for the
4777 genAddrOf: will be changed according to bug 863624
4779 * added files genutils.c and genutils.h which contain gen*
4780 debugged and optimised functions extracted from gen.c
4782 * glue.c: added variable 'externs' which holds extern symbols,
4783 pic16emitRegularMap: is modified to properly handle relocatable
4784 symbols under the new scheme,
4785 pic16createInterruptVect: is modified
4786 pic16printPublics: is modified to emit 'global' assembler directives,
4787 added pic16_printExterns to print extern symbols,
4788 pic16glue: initializes stack/frame pointer in the beginning of
4789 the assembly output. Temporary hack, will be corrected later,
4790 because gplink yet does not support stack and SDCC does not
4791 yet support a type of crt0.o object to create the final binary.
4793 * Removed many lines that contain 8051 legacy code.
4794 * The code is finally placed under a 'code' directive.
4795 * Added port specific options.
4797 * _process_pragma: simplified since now we do not need *special*
4798 include file to define SFR registers. But a separate header
4799 will be needed. This will be developed later.
4800 * _pic16_parseOptions: added, parses port specific options:
4801 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4802 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4803 --preplace-udata-with=
4805 * _pic16_setDefaultOptions: modified to initialize section names,
4806 but hack is temporarly out of order since it needs improvement.
4807 * _pic16_genAssemblerPreamble: configuration words are emitted by
4808 their address instead of their name. This part is incomplete and
4809 supports only the 18Fxx2 devices. Other devices will emit an error
4810 during assembly since they do not contain the same set of config
4812 * _pic16_genIVT: is modified,
4814 * pcode.c: added definitions for some hardware registers that are needed
4816 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4817 All PCI entries are updated. Now LFSR is supported.
4818 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4819 * added pic16_newpCodeOpLit2 to support instructions with
4820 two literal arguments
4821 * pic16_pCode2str: corrected code that emits assembler instructions
4822 with two literal operands and those that have an access bit modifier
4823 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4824 this fixes a bug which caused some labels to be lost, when an
4825 assembler directive was added, i.e. banksel,
4826 * pic16_FixRegisterBanking: improved logic that causes the insertion
4828 * InlineFunction: functions that are called once, are not any more
4829 inlined. This can be a port option in the future,
4831 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4833 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4834 hold the corresponding uninitialized symbols,
4835 * pic16_allocProcessorRegister: registers have explicit marked the
4837 * pic16_allocInternalRegister: registers are explicit marked as
4839 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4840 processing list, so bit registers were lost,
4843 * ralloc.h: added field 'accessBank' and original symbol operand
4844 in register definition,
4845 * removed the field isMapped from register definition,
4847 ** Several functions have been removed from various sources:
4848 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4849 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4850 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4851 pic16_assignRelocatableRegisters
4853 ** others have been introduced:
4854 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4855 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4857 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4859 * support/scripts/inc2h.pl: changed definition of BIT_AT
4860 to emit 'sbit at' instead of 'bit at'. This was a request.
4862 PIC16 port related preliminary changes:
4863 * gen.c: prefixed function popRegFromString with
4864 pic16_ and all references to it corrected
4865 * pcode.c: all pic16_pc_* hardware registers prefixed
4866 with underscore (_),
4867 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4868 * ralloc.c: newReg(): when register is REG_SFR then
4869 set address to rIdx,
4870 pic16_allocProcessorRegister(): marks register wasUsed=0
4871 pic16_writeUsedRegs(): added a call to assign processor
4872 registers via pic16_assignFixedRegisters
4874 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4876 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4877 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4878 variables in unused register banks. Also the SSEG is placed
4879 wherever there is enough space for it, and IDATA can be anywhere
4880 in internal RAM. For now compile using -Wl-Y[stack_size].
4881 The mem file is different for this option as well, since it
4882 makes no sense of talking about DSEG lenght.
4884 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4886 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4887 in certain cases, e.g. when ROM assignment, patch provided
4888 from Albert den Haan.
4890 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5933 A few small changes that speed up the peephole optimizer.
5937 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5939 Try to make the peephole optimizer smarter by maintaining
5940 an association between the assembly source code and the
5941 iCodes that originated them. Put this information to use
5942 with a new peephole rule condition "notVolatile" so that
5943 the rules can be aggressive yet still safe.
5948 * src/mcs51/peeph.def
5950 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5954 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5955 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5956 if the left or right operand symbols have the accuse flag set.
5958 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5960 Changed the type of the result of the ! (NOT) operator to char;
5961 previously it returned the same type as the source. This allows
5962 us to eliminate all the genFloatNot functions (all of its target
5963 implementations were very buggy) since !float can use the same
5966 * src/SDCCicode.c (ast2iCode): ! returns char
5967 * src/mcs51/gen.c (genNot, genNotFloat),
5968 * src/ds390/gen.c (genNot, genNotFloat),
5969 * src/z80/gen.c (genNot, genNotFloat),

5975 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5976 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5977 during interrupts. Ensure WSAVE is located at a shared bank address.
5978 2. Fixed page selection in some places
5979 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5980 the registers name strings.
5981 4. Fixed "signed / unsigned compare" compiler warnings.
5982 5. The PIC port manages its own allocation of the general purpose
5983 registers, but makes no attempt to reuse them. As a result when
5984 compiling it soon runs out of general purpose registers. Some
5985 additional code was added to the files pcode.c and device.c to walk
5986 through the function call tree and rename the registers so that they
5996 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5997 genPlus() & genMinus() when the result is the same as left or right

6003 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6005 Made bitfield a distinct type from bit so that bitfields
6006 convert as per ANSI C and bits retain their traditional
6007 boolean style behaviour. Implemented bitfield support in
6015 * src/ds390/gen.c: bit v bitfield split
6016 * src/z80/gen.c: New support for bitfields
6017 * support/regression/tests/bitfields.c: reenabled z80,
6020 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6022 Rules 246.x, 247.x relate to bitfields, the others speed up
6023 access to xdata mapped I/O devices.
6025 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6027 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6029 Cleaned up genPackBits and genUnpackBits and added two helper
6030 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6031 for literal assignments in genPackBits (thanks to Frieder for
6037 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6039 Fixed bug #748310 (pointer to function type mishandled when the
6040 function name is omitted). Also fixed a SIGSEGV when a function
6041 attribute (reentrant, etc) is used on a non-function or on a
6042 function but misplaced before the parameter list.
6044 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6046 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6069 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6071 Made the constant following the "interrupt" keyword optional. If
6072 omitted, the function will not automatically be given an entry
6073 in the interrupt vector table (similar to #pragma NOIV, but
6074 less syntacticly kludgy). The interrupt number is also now
6075 range checked. Also fixed a bug in the high order bit example

6096 unsigned, but are signed by default
6097 * src/SDCCval.c (constVal): rearranged
6098 * src/SDCCval.c (valMod): preliminary fix
6099 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6516 condition and ignore commands.
6518 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6520 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
6521 is in parts still quite out of date, I did changes as far as I felt makes sense
6522 for a non-native english speaker.
6523 Please feel free to add to the manual or to correct my changes.
6524 * doc/Makefile: undid touching the date of intermediate tex files.
6526 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6541 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6543 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
6544 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
6545 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
6546 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
6549 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6551 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6552 the regression tests I'm not brave enough to enable 245.b, 245.c
6553 * doc/sdccman.lyx: added latex preamble for hyperref package.
6554 Using pdflatex this will give you a hyperlinked pdf file with
6555 bookmarks. (prepend '%' before /usepackage if this breaks something)
6557 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6571 Applied patch from bug 737905 (renamed yylineo to mylineno):
6578 * src/pic16/pcode.c: Cleaned warnings
6579 * src/pic16/pcodeflow.c: Cleaned warnings

6593 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6595 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6596 it can be defined with CFLAGS when running configure
6597 * src/SDCCmain.c: fixed compiling + linking with object files
6599 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6601 * configure.in: configure for pic16 port,
6602 added --disable-pic16-port
6603 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6604 * src/SDCCmain.c: linkOptions is changed to set *,
6605 added if/endif conditional macros to remove options help
6606 messages from optionsTable when a port is not configured, added
6607 support for the PIc16 port in the ports table, when executing
6608 the compiler with no port specified on command line, a default
6609 port is selected with the new macro DEFAULT_PORT which is
6610 defined in port.h, in setDefaultOptions() linkOptions is removed
6611 from initialization assignment, since now it is a set,
6612 parseCmdLine uses setParseWithComma for linkOptions, in
6613 linkEdit() linkOptions are accessed with new function indexSet()
6614 which returns the i'th item of a set variable. See SDCCset.c, in
6615 linkEdit() when calling buildCmdLine(), added linkOptions as
6616 last argument. Now users can pass arguments to gplink via the
6617 -Wl option, main() uses pic16glue() to glue up pic16 programs
6618 * src/SDCCpeeph.c: various changes to support pic16
6619 * src/SDCCset.c: added function void *indexSet(set *, int) to
6620 return the i'th item of the set

6623 * src/clean.mk: added pic16 in CLEANALLPORTS variable
6624 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
6625 added macro DEFAULT_PORT
6626 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
6627 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6629 * src/pic16/glue.c: commented out some error producing lines
6630 * src/pic16/main.c: __config directives are commented out to stop
6631 gpasm complaining and test the linkage with gplink, _linkCmd and
6632 _asmCmd changed to be more gplink and gpasm friendly
6633 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6634 produced an error when parsed, peep rule 12 is added to utilize
6635 movff, but it is commented out since the pCode does not support
6636 yet a command with 2 address arguments
6638 2003-05-18 <johan AT balder>
6640 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6641 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6660 on entry now. Add tbreak. Other enhancements and fixes for use
6663 2003-05-12 Borut Razem <borut.razem AT siol.net>
6665 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6667 2003-05-11 Borut Razem <borut.razem AT siol.net>
6669 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6670 the path of bin directory, so that PATH is the only env. variable, which has to be set
6671 in case of standard installation.
6672 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7701 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7703 * in \sdcc\as\mcs51\ changed these files in order to create an
7704 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7705 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7706 following files to include the previous two files: aslink.dsp,
7707 Makefile.aslink, Makefile.bcc, and Makefile.in.
7709 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7710 .adb instead of .cdb
7712 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7714 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7715 value from option --iram-size.
7717 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7719 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7722 2002-09-18 <wiml AT hhhh.org>
7724 * SDCClrange.h: exposed setFromRange() and setToRange()
7725 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7726 packRegsForAccUse() (bug 542397)
7727 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7728 multiple times and emitting the fetch operations more than once
7729 added aopGetUsesAcc() function to allow binary operators to
7730 fetch their operands in the correct order; made genMinus() emit
7731 compact code for X = LITERAL - Y
7733 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7734 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7735 sprintf() in line 1267.
7737 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7738 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7741 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7742 Changes to aslink (All the changes are marked with 'JCF'):
7744 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7747 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7748 area BSEG. Also moves, if possible, the DATA area down into the internal
7749 ram so more space is available.
7751 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7754 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7755 not bytes. Function summary() which creates a memory usage summary
7756 file with extension .mem. Reports of overlaping stack and small stack
7757 size. If the space for the stack is less than 16 bytes aslink trows a
7760 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7761 the 8051. Option 'y' for memory summary output file.
7763 Changes to sdcc (All the changes are marked with 'JCF'):
7765 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7767 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7768 overlaying area for it (uses RegBankUsed[4]).
7770 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7771 bank zero as used by default. By default aslink locates the stack
7772 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7773 the creation of the .mem file. Delegates the allocation of data area
7774 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7775 the begining of the stack area to aslink.
7777 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7778 glue() in SDCCglue.c creates an area for it.
7780 2002-09-03 Borut Razem <borut.razem AT siol.net>
7781 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7782 sdcc/src/pic/glue.c:
7783 introduced atexit() handler for teporay files removal in case of
7784 errors, assertions, ...
7786 2002-08-29 Borut Razem <borut.razem AT siol.net>
7787 * sdcc/support/cpp2/auto-host_vc_in.h:
7788 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7789 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7790 Maybe there is a similar problem with BORLANDC? It should be checked!
7792 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7793 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7794 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7795 was not executed, and the compiler (cl) launched a warning:
7796 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7798 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7799 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

7811 - added Release configuration in VS projects
7812 - review of compiler an linker options
7813 - VC .exe files are generated in bin_vc directory, not to interfere
7814 with binaries generated from other projects (cygwin, mingw, bcc ...)
7816 * sdcc/src/yacc.dsp: added
7818 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7819 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7820 and insert the version number definitions from .version
7822 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7824 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7828 removed from CVS, generated automatically
7830 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7831 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7833 2002-08-11 Borut Razem <borut.razem AT siol.net>
7834 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7836 2002-08-10 Borut Razem <borut.razem AT siol.net>
7837 * src/SDCCmain.c (main):
7838 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7839 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7840 The consequence was that some temporary files were not removed.
7843 unification of code in functions tempfilename() and tempfile():
7844 function tempnam() is defined in Visual Studio 6.0 and .NET
7846 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7848 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7849 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7850 - removed compiler command line option /WX: Treats all warnings as errors
7851 - update a list of source files, included into the project
7853 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7854 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7855 changed project type to Generic Project so that can be correcly converted to VS.NET project
7857 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7859 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7863 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7864 added return 0 statements after assert() to make compiler happy
7866 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7867 added newline in the def file to keep MSC compiler satisfied
7869 * sdcc/src/z80/gen.c:
7870 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7871 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7872 - solved MSC error in function aopDump()
7874 * sdcc_vc.h: define PREFIX as "\\sdcc"
7876 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7932 were not getting allocated.
7934 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7937 Fixed left shift. Will promote the left side of a left shift
7938 if a) left shifting more than size of operand or b) when assigned
7939 to something size > size of left side
7941 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8051 * sdcc/src/SDCCloop.c:
8052 Previous fix was not good. basic blocks that have "break" or "return" are
8053 not really partof a loop , but live ranges used in these blocks should
8054 be live thru the entire loop, so set partOfLoop but don't add them to
8057 2002-02-21 <johan AT FRIJA>
