632 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
634 * device/lib/printf_large.c: removed inline assembly for portability and
635 readability. Use printf_fast if speed or size are more important.
636 * src/pic16/gen.c: removed conditions around use of DEBUGpc
637 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
639 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
641 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
642 prevent compiler warning
644 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
646 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
647 moved to level 0 and declared as static. Also they are explicit
648 placed in access bank. This was necessery because some times they
649 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
650 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
651 optimizations. Currently only compare to unsigned char is implemented,
652 * src/pic16/gen.c: added fReturnIdx array,
653 * (struct resolvedIfx) is moved to gen.h and made public,
654 * (struct _G): added sregsAlloc and sregsAllocSet fields,
655 * (aopForSym): added an optimization to directly store in stack of
656 the operand of a SEND iCode,
657 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
658 but as registers instead (AOP_REG) using the fReturnIdx array,
659 * (pic16_freeAsmop): remove the freed register from the
661 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
663 * (pic16_popGetTempRegCond): changed function prototype, now
664 function takes also a bitVector argument v which holds the current
665 set of registers that are allocated for stack access by aopForSym,
666 registers allocated in aopForSym for accessing stack symbols are not
667 any more part of the functions usedRegs field,
668 * (genCall): some times aopOp is called for a stack variable to be
669 send, aopForSym might perform the push, if this is true make sure
670 that genCall doesn't push the variable twice by testing _G.resDirect,
671 * (genFunction): changed testing for unspecified interrupt number
672 from 256 to INTNO_UNSPEC,
673 * modified selection scheme of frame pointer generation. Previously
674 if function did use local registers a frame pointer was generated,
675 now a frame pointer is generated only if function has arguments
676 (that need PLUSW2 register access), or has stack arguments, or the
677 compiler is not instructed to omit the frame pointer,
678 * (genEndFunction): before restoring local registers that were saved
679 in the function preamble, also restore the registers that *might*
680 have been allocated for stack access,
681 * (genRet): removed some old comments,
682 * (genCmp, the active (RN's) version): added a call to the
683 pic16_genCmp_special function to perform the compare with a more
684 robust and optimized way,
685 * (genInline): a feature has been added in inline code generation,
686 which allows a wildcard variable substitution when writing inline
687 assembly. Code is incomplete and experimental therefore undocumented,
688 * (genCast): changed order of aopOp for result and right to allow
689 aopForSym to directly load the result if possible,
690 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
691 perform an optimized compare on some selected special occasions,
692 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
693 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
694 generate an IVT any more,
695 * src/pic16/main.c (pic16_optionsTable): added command line option
697 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
698 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
700 * src/pic16/NOTES: Raphael Neider added in list of active developers
701 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
702 jumptable_end to prevent bug #,
703 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
704 inCond and outCond fields,
705 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
706 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
707 turn off register spilling,
708 * (packRegsForOneUse): synced with other ports' versions although it
709 is not used currently,
710 * (pic16_packRegisters): added an optimization while reading
711 structure bitfields, some registers may be saved (malloc code is
712 decreased by 80 bytes)
714 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
716 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
717 left is a bitfield, if yes, then don't optimize assignment. Perhaps
718 this can be optimized more?
720 2005-03-10 Raphael Neider <rneider AT web.de>
722 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
723 genNearPointerGet): (hopefully) fixed access to bitfields via
724 pointers (p->bitN = x; and x = p->bitN; failed)

1339 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
1341 (setFromConditionArgs): friendly operand parser for peephole rules,
1342 (operandBaseName, operandsNotRelated): new peephole condition
1343 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1344 architecture specific register naming into account, handles n-way
1345 comparisons, and supports quoted literals
1346 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
1348 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1356 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1358 Adding support for replacing ljmps with sjmps in jumptables
1359 generated for switch statements. For now you need to set the
1360 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1361 Now 4 algorithms for mcs51 jumptable generation are used:
1362 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1363 addresses loaded pc-relative for up to 112 cases and stack-pushing
1364 target addresses loaded with offset from dptr for up to 256 cases.
1366 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1367 * src/mcs51/main.c: adapted constants for switch table generation
1368 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1390 Large cummulative patch for pic16 port.
1391 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1392 to call when a stack overflow occurs,
1393 * (malloc.h): added CVS Id tag,
1394 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1396 * added libc directory. The current version of LibC contains string
1397 functions, ctype functions and macros and some functions of the
1398 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1399 be extensively tested in the future. Standard disclaimer here.
1400 Library is not automatically build yet. But one can build it by
1401 invoking 'make' inside the libc directory.
1402 * added ADC library under libio. Preliminary version yet.
1404 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1405 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1406 aopForRemat() now and not by pic16_aopOp(),
1407 * (pic16_popGetTempReg): removed warning messgae when allocating
1408 temporary registers, its a buggy feature and will be removed,
1409 * (pic16_popGet): set register instance field in AOP_CRY,
1410 * (pic16_outBitC): fixed for results in size greater than 1,
1411 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1412 * (pic16_storeForReturn): optimized return of 0,
1413 * (genCmp): experimental code for new genCmp which uses PIC18's
1414 special compare&skip instructions. Initial tests fail some times
1415 with variables grater than 1 byte in size, so new code is disabled,
1416 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1418 * (genCast): began a fix to optimize the casting of a bit to another
1419 bit, now assigning a bitfield to another bitfield will fail, sorry,
1420 * src/pic16/main.c: disabled the use of lr-support feature,
1421 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1422 * added some function prototypes, added function _debugf prototype,
1423 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1424 bits with offset (case PO_GPR_BIT),
1425 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1427 * (isBankInstruction): modified to return 0 for no banking instruction,
1428 and 1 for banking instruction,
1429 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1430 caused stop processing pCodes after a inline assembly block,
1431 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1432 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1433 registers when it shouldn't,
1434 * src/pic16/ralloc.c (allocReg): add preliminary support for
1435 supporting a limited set of temporary registers,
1437 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1439 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1440 genDataPointerSet): ensure assignments always copy in MSB to LSB
1442 (loadRegFromAop): recognize CLRH optimization,
1443 (genFunction): optimize RECEIVE iCodes in reentrant functions
1445 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1447 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1448 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1450 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1456 * device/lib/_gptrget.c (_gptrget),
1457 * device/lib/_gptrgetc.c (_gptrgetc),
1458 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1459 instead of sjmp to ret
1460 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1461 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1463 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4444 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4445 loaded with the linker search paths (-L arguments) and the libraries
4446 to be linked with the current source (-l arguments). Changes
4447 currently will affect only the pic16 port.
4448 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4449 include path the port specific paths and port specific libraries,
4450 * gplink command now contains the $3 argument,
4451 * src/pic16/device.h,
4452 * src/pic16/device.c,: structure PIC_device is made public and
4453 renamed to PIC16_device, the same for variable Pics which is renamed
4454 to Pics16. Updated all references to them.
4455 * src/pic16/glue.c (pic16glue): corrected bug with code
4456 initialization which bypassed the variable initializations block.
4458 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4459 COMPILE_FLAGS and added the --nostdinc option
4461 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4463 * device/include/mc68hc908jb8.h: Register defs for another member
4464 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4466 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4468 Documenting changes from previous commits.
4469 * configure.in (version 1.56),
4470 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4471 when generating output files to configure the pic16 library,
4472 but now I've commented it out, since gputils aren't installed in the
4473 SF compile farm, so library won't compile
4475 * device/lib/Makefile.in (version 1.56): initially I've added in
4476 target 'all' the prerequestive 'model-pic16' so it compiled the
4477 pic16 library, but now I've commented it out for the same reasons
4479 * added targets 'model-pic16' and 'objects-pic16' to compile the
4481 * added target 'port-specific-objects-pic16' to handle the
4482 generated libraries and copy them into the build/ directory
4483 * added target 'clean-intermediate-pic16' to clean intermediate
4484 files into pic16 directory
4485 * in target 'installdirs' added line to create directory pic16 in
4486 the installation path
4488 * device/include/Makefile.in (version 1.11): in target 'install'
4489 added lines to copy all header files to installation path,
4490 * in target 'installdirs' added line create directory for pic16
4491 headers in the installation path
4493 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4506 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4507 option so that it actually works. Made it specific to the z80, since
4508 the gbz80 doesn't have these kinds of I/O ports.
4510 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4512 * device/include/z180.h,

4525 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4527 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4528 changed interrupt vector table generation to only emit declared vectors.
4529 * device/include/Makefile.in: added missing backslash
4530 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

4534 Mainly changes to support compilation of the device libraries
4535 * src/pic16/device.c: stack is allocated via symbol and not
4536 via literal number. The symbol is placed in the corresponding
4537 position of the data ram
4538 * (pic16_dump_section): relocatable and absolute uninitialized
4539 data are now emitted in sorted order to reduce section naming,
4540 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4541 weren't marked as being in the access bank,
4543 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4545 Added portion of GNU PIC Library under the directory
4546 device/include/pic16 and device/lib/pic16. These files
4547 contain the declarations of SFRs for the PIC18Fxx2 devices.
4548 The directory is initialized via configure from toplevel.
4550 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4552 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4553 the spilllocations to be compared correctly
4555 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4557 * src/SDCCast.c (decorateType): fixed bug introduced today
4559 2004-01-12 Borut Razem <borut.razem AT siol.net>
4561 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4575 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4577 * doc/sdccman.lyx: Moved and added some sections, small changes
4578 all over. Telling LaTeX to be less strict with word spacing
4579 to better keep the right margin. Changed some notes about
4580 maintainance of the ports in section 3.2.1 - is it OK like this?
4582 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4584 SDCC source changes:
4585 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4619 UPPER for immediate operands,
4620 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4622 * src/pic16/peeph.def: all peepholes with movff are commented out,
4623 because there is a problem in the pcode peep optimizer,
4624 * src/pic16/ralloc.c: the register allocator can now reuse local
4625 function symbols for another function. This saves register usage.
4626 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4628 Added file src/pic16/NOTES with information about program writing on
4629 the current port version.

4638 * src/SDCCmain.c : fixed #872250: -l command line defined library
4639 files are scanned before standard library files
4641 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4658 gen51Code): more efficient parameter receive for --model-large
4661 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4664 * src/z80/main.c: added missed needLinkerScript flags (more than
4665 one port structure defined in these file)
4666 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4682 needLinkerScript flag
4684 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4685 * src/pic/glue.c: added variable udata_section_name to
4686 override default uninitialized data segment definition for
4687 devices only with SHAREBANK memory (reported from Erik Epetrich)
4688 * (pic14emitOverlay): modified to emit a commented overlay segment
4689 directive when no overlay data exist
4690 * (picglue): modified to emit uninitialized data segment
4691 according to udata_section_name

4696 arguments via -W option
4697 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4698 object file from '.rel' to '.o' in port->linker structure,
4699 changed size of fptr from 2 to 3 in port structure
4701 2004-01-07 Borut Razem <borut.razem AT siol.net>
4703 * support/scripts/sdcc.nsi: update PATH
4704 * support/scripts/sdcc.ico: craeted
4706 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4708 * device/include/Makefile.in: fix install
4709 * doc/Makefile: fix install
4711 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4713 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4715 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4716 how the function variable allocation summary is displayed; also
4717 include information about variables allocated to the overlay
4720 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4722 * as/mcs51/lkmain.c: Help about -Y option

4732 LEFT_OP (left shift)
4734 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4736 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4737 (default behaviour).
4739 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4741 A python script to validate compiler diagnostic messages. It can be
4742 used to verify that sdcc complains about bad c source code and
4743 gives a good location of the error.
4744 * support/valdiag/Makefile,
4745 * support/valdiag/valdiag.py,
4746 * support/valdiag/tests/*
4748 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4750 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4751 * src/SDCCsymt.c (newEnumType),

4759 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4761 * src/common.h: added ifndef/define/endif macros
4762 around the header file.
4763 Bug reported from Jesus Calvino-Fraga
4765 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4767 * sdcc.spec: updated
4768 * device/include/Makefile.in: don't install CVS directories
4769 * device/lib/Makefile.in: added removal of CVS directories after install
4770 * doc/Makefile: fixed install, added local_icons
4771 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4772 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4773 * src/ds390/gen.c (genRightShift): fixed bug #870788
4774 * src/SDCCast.c (decorateType): fixed bug #870781
4776 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4778 PIC16 port related changes:
4779 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4780 added variable stackPos,
4782 * gen.c: genCall, assignResultValue: added support for
4783 pushing/retrieving function parameters to/from stack,
4784 genFunction,genEndFunction: setup stack frame for the
4786 genAddrOf: will be changed according to bug 863624
4788 * added files genutils.c and genutils.h which contain gen*
4789 debugged and optimised functions extracted from gen.c
4791 * glue.c: added variable 'externs' which holds extern symbols,
4792 pic16emitRegularMap: is modified to properly handle relocatable
4793 symbols under the new scheme,
4794 pic16createInterruptVect: is modified
4795 pic16printPublics: is modified to emit 'global' assembler directives,
4796 added pic16_printExterns to print extern symbols,
4797 pic16glue: initializes stack/frame pointer in the beginning of
4798 the assembly output. Temporary hack, will be corrected later,
4799 because gplink yet does not support stack and SDCC does not
4800 yet support a type of crt0.o object to create the final binary.
4802 * Removed many lines that contain 8051 legacy code.
4803 * The code is finally placed under a 'code' directive.
4804 * Added port specific options.
4806 * _process_pragma: simplified since now we do not need *special*
4807 include file to define SFR registers. But a separate header
4808 will be needed. This will be developed later.
4809 * _pic16_parseOptions: added, parses port specific options:
4810 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4811 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4812 --preplace-udata-with=
4814 * _pic16_setDefaultOptions: modified to initialize section names,
4815 but hack is temporarly out of order since it needs improvement.
4816 * _pic16_genAssemblerPreamble: configuration words are emitted by
4817 their address instead of their name. This part is incomplete and
4818 supports only the 18Fxx2 devices. Other devices will emit an error
4819 during assembly since they do not contain the same set of config
4821 * _pic16_genIVT: is modified,
4823 * pcode.c: added definitions for some hardware registers that are needed
4825 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4826 All PCI entries are updated. Now LFSR is supported.
4827 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4828 * added pic16_newpCodeOpLit2 to support instructions with
4829 two literal arguments
4830 * pic16_pCode2str: corrected code that emits assembler instructions
4831 with two literal operands and those that have an access bit modifier
4832 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4833 this fixes a bug which caused some labels to be lost, when an
4834 assembler directive was added, i.e. banksel,
4835 * pic16_FixRegisterBanking: improved logic that causes the insertion
4837 * InlineFunction: functions that are called once, are not any more
4838 inlined. This can be a port option in the future,
4840 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4842 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4843 hold the corresponding uninitialized symbols,
4844 * pic16_allocProcessorRegister: registers have explicit marked the
4846 * pic16_allocInternalRegister: registers are explicit marked as
4848 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4849 processing list, so bit registers were lost,
4852 * ralloc.h: added field 'accessBank' and original symbol operand
4853 in register definition,
4854 * removed the field isMapped from register definition,
4856 ** Several functions have been removed from various sources:
4857 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4858 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4859 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4860 pic16_assignRelocatableRegisters
4862 ** others have been introduced:
4863 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4864 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4866 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4868 * support/scripts/inc2h.pl: changed definition of BIT_AT
4869 to emit 'sbit at' instead of 'bit at'. This was a request.
4871 PIC16 port related preliminary changes:
4872 * gen.c: prefixed function popRegFromString with
4873 pic16_ and all references to it corrected
4874 * pcode.c: all pic16_pc_* hardware registers prefixed
4875 with underscore (_),
4876 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4877 * ralloc.c: newReg(): when register is REG_SFR then
4878 set address to rIdx,
4879 pic16_allocProcessorRegister(): marks register wasUsed=0
4880 pic16_writeUsedRegs(): added a call to assign processor
4881 registers via pic16_assignFixedRegisters
4883 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4885 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4886 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4887 variables in unused register banks. Also the SSEG is placed
4888 wherever there is enough space for it, and IDATA can be anywhere
4889 in internal RAM. For now compile using -Wl-Y[stack_size].
4890 The mem file is different for this option as well, since it
4891 makes no sense of talking about DSEG lenght.
4893 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4895 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4896 in certain cases, e.g. when ROM assignment, patch provided
4897 from Albert den Haan.
4899 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5924 type for bits was changed. It resulted in bit variables becoming
5925 global, which is not permitted in PIC 14 assembly output.
5927 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5929 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5931 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5933 Z80 and MCS51 linkers complaint if a public symbol is defined
5934 in more than one library module:

5942 A few small changes that speed up the peephole optimizer.
5946 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5948 Try to make the peephole optimizer smarter by maintaining
5949 an association between the assembly source code and the
5950 iCodes that originated them. Put this information to use
5951 with a new peephole rule condition "notVolatile" so that
5952 the rules can be aggressive yet still safe.
5957 * src/mcs51/peeph.def
5959 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5963 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5964 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5965 if the left or right operand symbols have the accuse flag set.
5967 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5969 Changed the type of the result of the ! (NOT) operator to char;
5970 previously it returned the same type as the source. This allows
5971 us to eliminate all the genFloatNot functions (all of its target
5972 implementations were very buggy) since !float can use the same
5975 * src/SDCCicode.c (ast2iCode): ! returns char

5984 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5985 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5986 during interrupts. Ensure WSAVE is located at a shared bank address.
5987 2. Fixed page selection in some places
5988 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5989 the registers name strings.
5990 4. Fixed "signed / unsigned compare" compiler warnings.
5991 5. The PIC port manages its own allocation of the general purpose
5992 registers, but makes no attempt to reuse them. As a result when
5993 compiling it soon runs out of general purpose registers. Some
5994 additional code was added to the files pcode.c and device.c to walk
5995 through the function call tree and rename the registers so that they
6005 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6006 genPlus() & genMinus() when the result is the same as left or right

6012 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6014 Made bitfield a distinct type from bit so that bitfields
6015 convert as per ANSI C and bits retain their traditional
6016 boolean style behaviour. Implemented bitfield support in
6024 * src/ds390/gen.c: bit v bitfield split
6025 * src/z80/gen.c: New support for bitfields
6026 * support/regression/tests/bitfields.c: reenabled z80,
6029 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6031 Rules 246.x, 247.x relate to bitfields, the others speed up
6032 access to xdata mapped I/O devices.
6034 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6036 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6038 Cleaned up genPackBits and genUnpackBits and added two helper
6039 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6040 for literal assignments in genPackBits (thanks to Frieder for
6046 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6048 Fixed bug #748310 (pointer to function type mishandled when the
6049 function name is omitted). Also fixed a SIGSEGV when a function
6050 attribute (reentrant, etc) is used on a non-function or on a
6051 function but misplaced before the parameter list.
6053 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6055 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6078 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6080 Made the constant following the "interrupt" keyword optional. If
6081 omitted, the function will not automatically be given an entry
6082 in the interrupt vector table (similar to #pragma NOIV, but
6083 less syntacticly kludgy). The interrupt number is also now
6084 range checked. Also fixed a bug in the high order bit example

6102 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6103 be re-activated by defining REDUCE_LITERALS)
6104 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6105 unsigned, but are signed by default
6106 * src/SDCCval.c (constVal): rearranged
6107 * src/SDCCval.c (valMod): preliminary fix
6108 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6527 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6529 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
6530 is in parts still quite out of date, I did changes as far as I felt makes sense
6531 for a non-native english speaker.
6532 Please feel free to add to the manual or to correct my changes.
6533 * doc/Makefile: undid touching the date of intermediate tex files.
6535 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6550 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6552 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
6553 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
6554 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
6555 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
6558 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6560 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6561 the regression tests I'm not brave enough to enable 245.b, 245.c
6562 * doc/sdccman.lyx: added latex preamble for hyperref package.
6563 Using pdflatex this will give you a hyperlinked pdf file with
6564 bookmarks. (prepend '%' before /usepackage if this breaks something)
6566 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6578 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
6580 Applied patch from bug 737905 (renamed yylineo to mylineno):
6587 * src/pic16/pcode.c: Cleaned warnings
6588 * src/pic16/pcodeflow.c: Cleaned warnings
6589 * src/pic16/pcoderegs.c: Cleaned warnings

6600 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
6602 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6604 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6605 it can be defined with CFLAGS when running configure
6606 * src/SDCCmain.c: fixed compiling + linking with object files
6608 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6610 * configure.in: configure for pic16 port,
6611 added --disable-pic16-port
6612 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6613 * src/SDCCmain.c: linkOptions is changed to set *,
6614 added if/endif conditional macros to remove options help
6615 messages from optionsTable when a port is not configured, added
6616 support for the PIc16 port in the ports table, when executing
6617 the compiler with no port specified on command line, a default
6618 port is selected with the new macro DEFAULT_PORT which is
6619 defined in port.h, in setDefaultOptions() linkOptions is removed
6620 from initialization assignment, since now it is a set,
6621 parseCmdLine uses setParseWithComma for linkOptions, in
6622 linkEdit() linkOptions are accessed with new function indexSet()
6623 which returns the i'th item of a set variable. See SDCCset.c, in
6624 linkEdit() when calling buildCmdLine(), added linkOptions as
6625 last argument. Now users can pass arguments to gplink via the
6626 -Wl option, main() uses pic16glue() to glue up pic16 programs
6627 * src/SDCCpeeph.c: various changes to support pic16
6628 * src/SDCCset.c: added function void *indexSet(set *, int) to

6636 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6638 * src/pic16/glue.c: commented out some error producing lines
6639 * src/pic16/main.c: __config directives are commented out to stop
6640 gpasm complaining and test the linkage with gplink, _linkCmd and
6641 _asmCmd changed to be more gplink and gpasm friendly
6642 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6643 produced an error when parsed, peep rule 12 is added to utilize
6644 movff, but it is commented out since the pCode does not support
6645 yet a command with 2 address arguments
6647 2003-05-18 <johan AT balder>
6649 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6650 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6651 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

6669 on entry now. Add tbreak. Other enhancements and fixes for use
6672 2003-05-12 Borut Razem <borut.razem AT siol.net>
6674 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6676 2003-05-11 Borut Razem <borut.razem AT siol.net>
6678 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6679 the path of bin directory, so that PATH is the only env. variable, which has to be set
6680 in case of standard installation.
6681 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7710 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7712 * in \sdcc\as\mcs51\ changed these files in order to create an
7713 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7714 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7715 following files to include the previous two files: aslink.dsp,
7716 Makefile.aslink, Makefile.bcc, and Makefile.in.
7718 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7719 .adb instead of .cdb
7721 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7723 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7724 value from option --iram-size.
7726 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7728 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7731 2002-09-18 <wiml AT hhhh.org>
7733 * SDCClrange.h: exposed setFromRange() and setToRange()
7734 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7735 packRegsForAccUse() (bug 542397)
7736 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7737 multiple times and emitting the fetch operations more than once
7738 added aopGetUsesAcc() function to allow binary operators to
7739 fetch their operands in the correct order; made genMinus() emit
7740 compact code for X = LITERAL - Y
7742 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7743 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7744 sprintf() in line 1267.
7746 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7747 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7750 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7751 Changes to aslink (All the changes are marked with 'JCF'):
7753 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7756 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7757 area BSEG. Also moves, if possible, the DATA area down into the internal
7758 ram so more space is available.
7760 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7763 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7764 not bytes. Function summary() which creates a memory usage summary
7765 file with extension .mem. Reports of overlaping stack and small stack
7766 size. If the space for the stack is less than 16 bytes aslink trows a
7769 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7770 the 8051. Option 'y' for memory summary output file.
7772 Changes to sdcc (All the changes are marked with 'JCF'):
7774 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7776 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7777 overlaying area for it (uses RegBankUsed[4]).
7779 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7780 bank zero as used by default. By default aslink locates the stack
7781 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7782 the creation of the .mem file. Delegates the allocation of data area
7783 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7784 the begining of the stack area to aslink.
7786 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7787 glue() in SDCCglue.c creates an area for it.
7789 2002-09-03 Borut Razem <borut.razem AT siol.net>
7790 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7791 sdcc/src/pic/glue.c:
7792 introduced atexit() handler for teporay files removal in case of
7793 errors, assertions, ...
7795 2002-08-29 Borut Razem <borut.razem AT siol.net>
7796 * sdcc/support/cpp2/auto-host_vc_in.h:
7797 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7798 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7799 Maybe there is a similar problem with BORLANDC? It should be checked!
7801 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7802 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7803 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7804 was not executed, and the compiler (cl) launched a warning:
7805 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7807 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7808 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

7820 - added Release configuration in VS projects
7821 - review of compiler an linker options
7822 - VC .exe files are generated in bin_vc directory, not to interfere
7823 with binaries generated from other projects (cygwin, mingw, bcc ...)
7825 * sdcc/src/yacc.dsp: added
7827 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7828 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7829 and insert the version number definitions from .version
7831 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7833 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7843 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7845 2002-08-10 Borut Razem <borut.razem AT siol.net>
7846 * src/SDCCmain.c (main):
7847 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7848 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7849 The consequence was that some temporary files were not removed.
7852 unification of code in functions tempfilename() and tempfile():
7853 function tempnam() is defined in Visual Studio 6.0 and .NET
7855 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7857 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7858 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7859 - removed compiler command line option /WX: Treats all warnings as errors
7860 - update a list of source files, included into the project
7862 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7863 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7864 changed project type to Generic Project so that can be correcly converted to VS.NET project
7866 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7868 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7872 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7873 added return 0 statements after assert() to make compiler happy
7875 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7876 added newline in the def file to keep MSC compiler satisfied
7878 * sdcc/src/z80/gen.c:
7879 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7880 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7881 - solved MSC error in function aopDump()
7883 * sdcc_vc.h: define PREFIX as "\\sdcc"
7885 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7941 were not getting allocated.
7943 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7946 Fixed left shift. Will promote the left side of a left shift
7947 if a) left shifting more than size of operand or b) when assigned
7948 to something size > size of left side
7950 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8060 * sdcc/src/SDCCloop.c:
8061 Previous fix was not good. basic blocks that have "break" or "return" are
8062 not really partof a loop , but live ranges used in these blocks should
8063 be live thru the entire loop, so set partOfLoop but don't add them to
