568 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
569 always available in leading double underscore form. The C99 support is
570 mostly missing, but it's a start.
571 * support/regression/tests/bug-227710.c: fixed nonconforming use of
572 reserved identifier "__data".

650 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
652 * device/lib/printf_large.c: removed inline assembly for portability and
653 readability. Use printf_fast if speed or size are more important.
654 * src/pic16/gen.c: removed conditions around use of DEBUGpc
655 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
657 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
659 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
660 prevent compiler warning
662 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
664 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
665 moved to level 0 and declared as static. Also they are explicit
666 placed in access bank. This was necessery because some times they
667 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
668 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
669 optimizations. Currently only compare to unsigned char is implemented,
670 * src/pic16/gen.c: added fReturnIdx array,
671 * (struct resolvedIfx) is moved to gen.h and made public,
672 * (struct _G): added sregsAlloc and sregsAllocSet fields,
673 * (aopForSym): added an optimization to directly store in stack of
674 the operand of a SEND iCode,
675 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
676 but as registers instead (AOP_REG) using the fReturnIdx array,
677 * (pic16_freeAsmop): remove the freed register from the
679 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
681 * (pic16_popGetTempRegCond): changed function prototype, now
682 function takes also a bitVector argument v which holds the current
683 set of registers that are allocated for stack access by aopForSym,
684 registers allocated in aopForSym for accessing stack symbols are not
685 any more part of the functions usedRegs field,
686 * (genCall): some times aopOp is called for a stack variable to be
687 send, aopForSym might perform the push, if this is true make sure
688 that genCall doesn't push the variable twice by testing _G.resDirect,
689 * (genFunction): changed testing for unspecified interrupt number
690 from 256 to INTNO_UNSPEC,
691 * modified selection scheme of frame pointer generation. Previously
692 if function did use local registers a frame pointer was generated,
693 now a frame pointer is generated only if function has arguments
694 (that need PLUSW2 register access), or has stack arguments, or the
695 compiler is not instructed to omit the frame pointer,
696 * (genEndFunction): before restoring local registers that were saved
697 in the function preamble, also restore the registers that *might*
698 have been allocated for stack access,
699 * (genRet): removed some old comments,
700 * (genCmp, the active (RN's) version): added a call to the
701 pic16_genCmp_special function to perform the compare with a more
702 robust and optimized way,
703 * (genInline): a feature has been added in inline code generation,
704 which allows a wildcard variable substitution when writing inline
705 assembly. Code is incomplete and experimental therefore undocumented,
706 * (genCast): changed order of aopOp for result and right to allow
707 aopForSym to directly load the result if possible,
708 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
709 perform an optimized compare on some selected special occasions,
710 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
711 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
712 generate an IVT any more,
713 * src/pic16/main.c (pic16_optionsTable): added command line option
715 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
716 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
718 * src/pic16/NOTES: Raphael Neider added in list of active developers
719 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
720 jumptable_end to prevent bug #,
721 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
722 inCond and outCond fields,
723 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
724 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
725 turn off register spilling,
726 * (packRegsForOneUse): synced with other ports' versions although it
727 is not used currently,
728 * (pic16_packRegisters): added an optimization while reading
729 structure bitfields, some registers may be saved (malloc code is
730 decreased by 80 bytes)
732 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
734 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
735 left is a bitfield, if yes, then don't optimize assignment. Perhaps
736 this can be optimized more?
738 2005-03-10 Raphael Neider <rneider AT web.de>
740 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
741 genNearPointerGet): (hopefully) fixed access to bitfields via
742 pointers (p->bitN = x; and x = p->bitN; failed)
744 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
746 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1359 (setFromConditionArgs): friendly operand parser for peephole rules,
1360 (operandBaseName, operandsNotRelated): new peephole condition
1361 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1362 architecture specific register naming into account, handles n-way
1363 comparisons, and supports quoted literals

1374 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1376 Adding support for replacing ljmps with sjmps in jumptables
1377 generated for switch statements. For now you need to set the
1378 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1379 Now 4 algorithms for mcs51 jumptable generation are used:
1380 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1381 addresses loaded pc-relative for up to 112 cases and stack-pushing
1382 target addresses loaded with offset from dptr for up to 256 cases.

1409 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1410 to call when a stack overflow occurs,
1411 * (malloc.h): added CVS Id tag,
1412 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1414 * added libc directory. The current version of LibC contains string
1415 functions, ctype functions and macros and some functions of the
1416 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1417 be extensively tested in the future. Standard disclaimer here.
1418 Library is not automatically build yet. But one can build it by
1419 invoking 'make' inside the libc directory.
1420 * added ADC library under libio. Preliminary version yet.
1422 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1429 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1430 * (pic16_storeForReturn): optimized return of 0,
1431 * (genCmp): experimental code for new genCmp which uses PIC18's
1432 special compare&skip instructions. Initial tests fail some times
1433 with variables grater than 1 byte in size, so new code is disabled,
1434 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1436 * (genCast): began a fix to optimize the casting of a bit to another
1437 bit, now assigning a bitfield to another bitfield will fail, sorry,
1438 * src/pic16/main.c: disabled the use of lr-support feature,
1439 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1440 * added some function prototypes, added function _debugf prototype,

1442 bits with offset (case PO_GPR_BIT),
1443 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1445 * (isBankInstruction): modified to return 0 for no banking instruction,
1446 and 1 for banking instruction,
1447 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1448 caused stop processing pCodes after a inline assembly block,
1449 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1450 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1451 registers when it shouldn't,
1452 * src/pic16/ralloc.c (allocReg): add preliminary support for
1453 supporting a limited set of temporary registers,
1455 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1457 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1458 genDataPointerSet): ensure assignments always copy in MSB to LSB
1460 (loadRegFromAop): recognize CLRH optimization,
1461 (genFunction): optimize RECEIVE iCodes in reentrant functions
1463 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1465 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1466 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1468 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1474 * device/lib/_gptrget.c (_gptrget),
1475 * device/lib/_gptrgetc.c (_gptrgetc),
1476 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1477 instead of sjmp to ret
1478 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1479 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1481 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4460 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4462 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4463 loaded with the linker search paths (-L arguments) and the libraries
4464 to be linked with the current source (-l arguments). Changes
4465 currently will affect only the pic16 port.
4466 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4467 include path the port specific paths and port specific libraries,
4468 * gplink command now contains the $3 argument,
4469 * src/pic16/device.h,
4470 * src/pic16/device.c,: structure PIC_device is made public and
4471 renamed to PIC16_device, the same for variable Pics which is renamed
4472 to Pics16. Updated all references to them.
4473 * src/pic16/glue.c (pic16glue): corrected bug with code
4474 initialization which bypassed the variable initializations block.
4476 * device/lib/pic16/Makefile.rules: removed --penable-stack from

4484 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4486 Documenting changes from previous commits.
4487 * configure.in (version 1.56),
4488 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4489 when generating output files to configure the pic16 library,
4490 but now I've commented it out, since gputils aren't installed in the
4491 SF compile farm, so library won't compile
4493 * device/lib/Makefile.in (version 1.56): initially I've added in
4494 target 'all' the prerequestive 'model-pic16' so it compiled the
4495 pic16 library, but now I've commented it out for the same reasons
4497 * added targets 'model-pic16' and 'objects-pic16' to compile the
4499 * added target 'port-specific-objects-pic16' to handle the
4500 generated libraries and copy them into the build/ directory
4501 * added target 'clean-intermediate-pic16' to clean intermediate
4502 files into pic16 directory
4503 * in target 'installdirs' added line to create directory pic16 in
4504 the installation path
4506 * device/include/Makefile.in (version 1.11): in target 'install'
4507 added lines to copy all header files to installation path,
4508 * in target 'installdirs' added line create directory for pic16
4509 headers in the installation path
4511 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4524 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4525 option so that it actually works. Made it specific to the z80, since
4526 the gbz80 doesn't have these kinds of I/O ports.
4528 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4530 * device/include/z180.h,

4543 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4545 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4546 changed interrupt vector table generation to only emit declared vectors.
4547 * device/include/Makefile.in: added missing backslash
4548 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4550 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4552 Mainly changes to support compilation of the device libraries
4553 * src/pic16/device.c: stack is allocated via symbol and not
4554 via literal number. The symbol is placed in the corresponding
4555 position of the data ram
4556 * (pic16_dump_section): relocatable and absolute uninitialized
4557 data are now emitted in sorted order to reduce section naming,
4558 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4559 weren't marked as being in the access bank,
4561 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4563 Added portion of GNU PIC Library under the directory
4564 device/include/pic16 and device/lib/pic16. These files
4565 contain the declarations of SFRs for the PIC18Fxx2 devices.
4566 The directory is initialized via configure from toplevel.
4568 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4570 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4571 the spilllocations to be compared correctly
4573 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4575 * src/SDCCast.c (decorateType): fixed bug introduced today
4577 2004-01-12 Borut Razem <borut.razem AT siol.net>
4579 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4582 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4584 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4585 in simpler and even better code
4587 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4589 * src/SDCCicode.c (operandOperation): fixed bug #874819

4593 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4595 * doc/sdccman.lyx: Moved and added some sections, small changes
4596 all over. Telling LaTeX to be less strict with word spacing
4597 to better keep the right margin. Changed some notes about
4598 maintainance of the ports in section 3.2.1 - is it OK like this?
4600 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4602 SDCC source changes:
4603 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4636 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4637 UPPER for immediate operands,
4638 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4640 * src/pic16/peeph.def: all peepholes with movff are commented out,
4641 because there is a problem in the pcode peep optimizer,
4642 * src/pic16/ralloc.c: the register allocator can now reuse local
4643 function symbols for another function. This saves register usage.
4644 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4646 Added file src/pic16/NOTES with information about program writing on
4647 the current port version.

4656 * src/SDCCmain.c : fixed #872250: -l command line defined library
4657 files are scanned before standard library files
4659 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4673 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4675 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
4676 gen51Code): more efficient parameter receive for --model-large
4679 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4682 * src/z80/main.c: added missed needLinkerScript flags (more than
4683 one port structure defined in these file)
4684 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
4687 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

4690 * src/port.h: added flag needLinkerScript in port->linker
4691 structure to inform whether to create a .lnk file or not,
4699 * src/z80/main.c: changed appropriately to configure
4700 needLinkerScript flag
4702 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4703 * src/pic/glue.c: added variable udata_section_name to
4704 override default uninitialized data segment definition for
4705 devices only with SHAREBANK memory (reported from Erik Epetrich)
4706 * (pic14emitOverlay): modified to emit a commented overlay segment
4707 directive when no overlay data exist
4708 * (picglue): modified to emit uninitialized data segment
4709 according to udata_section_name

4714 arguments via -W option
4715 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4716 object file from '.rel' to '.o' in port->linker structure,
4717 changed size of fptr from 2 to 3 in port structure
4719 2004-01-07 Borut Razem <borut.razem AT siol.net>
4721 * support/scripts/sdcc.nsi: update PATH
4722 * support/scripts/sdcc.ico: craeted
4724 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4726 * device/include/Makefile.in: fix install
4727 * doc/Makefile: fix install
4729 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4731 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4733 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4734 how the function variable allocation summary is displayed; also
4735 include information about variables allocated to the overlay
4738 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4740 * as/mcs51/lkmain.c: Help about -Y option

4750 LEFT_OP (left shift)
4752 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4754 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4755 (default behaviour).
4757 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4759 A python script to validate compiler diagnostic messages. It can be
4760 used to verify that sdcc complains about bad c source code and
4761 gives a good location of the error.
4762 * support/valdiag/Makefile,
4763 * support/valdiag/valdiag.py,
4764 * support/valdiag/tests/*
4766 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4768 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4769 * src/SDCCsymt.c (newEnumType),

4777 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4779 * src/common.h: added ifndef/define/endif macros
4780 around the header file.
4781 Bug reported from Jesus Calvino-Fraga
4783 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4785 * sdcc.spec: updated
4786 * device/include/Makefile.in: don't install CVS directories
4787 * device/lib/Makefile.in: added removal of CVS directories after install
4788 * doc/Makefile: fixed install, added local_icons
4789 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4790 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4791 * src/ds390/gen.c (genRightShift): fixed bug #870788
4792 * src/SDCCast.c (decorateType): fixed bug #870781
4794 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4796 PIC16 port related changes:
4797 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4798 added variable stackPos,
4800 * gen.c: genCall, assignResultValue: added support for
4801 pushing/retrieving function parameters to/from stack,
4802 genFunction,genEndFunction: setup stack frame for the
4804 genAddrOf: will be changed according to bug 863624
4806 * added files genutils.c and genutils.h which contain gen*
4807 debugged and optimised functions extracted from gen.c
4809 * glue.c: added variable 'externs' which holds extern symbols,
4810 pic16emitRegularMap: is modified to properly handle relocatable
4811 symbols under the new scheme,
4812 pic16createInterruptVect: is modified
4813 pic16printPublics: is modified to emit 'global' assembler directives,
4814 added pic16_printExterns to print extern symbols,
4815 pic16glue: initializes stack/frame pointer in the beginning of
4816 the assembly output. Temporary hack, will be corrected later,
4817 because gplink yet does not support stack and SDCC does not
4818 yet support a type of crt0.o object to create the final binary.
4820 * Removed many lines that contain 8051 legacy code.
4821 * The code is finally placed under a 'code' directive.
4822 * Added port specific options.
4824 * _process_pragma: simplified since now we do not need *special*
4825 include file to define SFR registers. But a separate header
4826 will be needed. This will be developed later.
4827 * _pic16_parseOptions: added, parses port specific options:
4828 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4829 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4830 --preplace-udata-with=
4832 * _pic16_setDefaultOptions: modified to initialize section names,
4833 but hack is temporarly out of order since it needs improvement.
4834 * _pic16_genAssemblerPreamble: configuration words are emitted by
4835 their address instead of their name. This part is incomplete and
4836 supports only the 18Fxx2 devices. Other devices will emit an error
4837 during assembly since they do not contain the same set of config
4839 * _pic16_genIVT: is modified,
4841 * pcode.c: added definitions for some hardware registers that are needed
4843 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4844 All PCI entries are updated. Now LFSR is supported.
4845 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4846 * added pic16_newpCodeOpLit2 to support instructions with
4847 two literal arguments
4848 * pic16_pCode2str: corrected code that emits assembler instructions
4849 with two literal operands and those that have an access bit modifier
4850 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4851 this fixes a bug which caused some labels to be lost, when an
4852 assembler directive was added, i.e. banksel,
4853 * pic16_FixRegisterBanking: improved logic that causes the insertion
4855 * InlineFunction: functions that are called once, are not any more
4856 inlined. This can be a port option in the future,
4858 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4860 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4861 hold the corresponding uninitialized symbols,
4862 * pic16_allocProcessorRegister: registers have explicit marked the
4864 * pic16_allocInternalRegister: registers are explicit marked as
4866 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4867 processing list, so bit registers were lost,
4870 * ralloc.h: added field 'accessBank' and original symbol operand
4871 in register definition,
4872 * removed the field isMapped from register definition,
4874 ** Several functions have been removed from various sources:
4875 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4876 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4877 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4878 pic16_assignRelocatableRegisters
4880 ** others have been introduced:
4881 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4882 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4884 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4886 * support/scripts/inc2h.pl: changed definition of BIT_AT
4887 to emit 'sbit at' instead of 'bit at'. This was a request.
4889 PIC16 port related preliminary changes:
4890 * gen.c: prefixed function popRegFromString with
4891 pic16_ and all references to it corrected
4892 * pcode.c: all pic16_pc_* hardware registers prefixed
4893 with underscore (_),
4894 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4895 * ralloc.c: newReg(): when register is REG_SFR then
4896 set address to rIdx,
4897 pic16_allocProcessorRegister(): marks register wasUsed=0
4898 pic16_writeUsedRegs(): added a call to assign processor
4899 registers via pic16_assignFixedRegisters
4901 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4903 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4904 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4905 variables in unused register banks. Also the SSEG is placed
4906 wherever there is enough space for it, and IDATA can be anywhere
4907 in internal RAM. For now compile using -Wl-Y[stack_size].
4908 The mem file is different for this option as well, since it
4909 makes no sense of talking about DSEG lenght.
4911 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4913 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4914 in certain cases, e.g. when ROM assignment, patch provided
4915 from Albert den Haan.
4917 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
4919 Many signedness and type propagation fixes:
4920 * src/SDCCicode.c: made geniCodeCast() static
4921 replaced SPEC_ by IS_ (cosmetic)
4922 (operandOperation): fixed div and mod operation
4923 (usualBinaryConversions): added support for promotion of char
4924 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
4925 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
4926 (geniCodeAdd): an array index will stay unsigned, even if promoted

5923 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5924 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5925 If they pop r0/r1 they must be called in the opposite order than aopOp().
5926 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5927 (resp. --stack-auto), prepared for --xstack

5936 these ports have their own __sdcc_external_start()
5938 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5940 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5941 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5942 type for bits was changed. It resulted in bit variables becoming
5943 global, which is not permitted in PIC 14 assembly output.
5945 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5947 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5949 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5951 Z80 and MCS51 linkers complaint if a public symbol is defined

5960 A few small changes that speed up the peephole optimizer.
5964 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5966 Try to make the peephole optimizer smarter by maintaining
5967 an association between the assembly source code and the
5968 iCodes that originated them. Put this information to use
5969 with a new peephole rule condition "notVolatile" so that
5970 the rules can be aggressive yet still safe.
5975 * src/mcs51/peeph.def
5977 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5981 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5982 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5983 if the left or right operand symbols have the accuse flag set.
5985 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5987 Changed the type of the result of the ! (NOT) operator to char;
5988 previously it returned the same type as the source. This allows
5989 us to eliminate all the genFloatNot functions (all of its target
5990 implementations were very buggy) since !float can use the same
5993 * src/SDCCicode.c (ast2iCode): ! returns char

5995 * src/ds390/gen.c (genNot, genNotFloat),
5996 * src/z80/gen.c (genNot, genNotFloat),
5997 * src/pic/gen.c (genNot, genNotFloat),
5998 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6002 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6003 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6004 during interrupts. Ensure WSAVE is located at a shared bank address.
6005 2. Fixed page selection in some places
6006 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6007 the registers name strings.
6008 4. Fixed "signed / unsigned compare" compiler warnings.
6009 5. The PIC port manages its own allocation of the general purpose
6010 registers, but makes no attempt to reuse them. As a result when
6011 compiling it soon runs out of general purpose registers. Some
6012 additional code was added to the files pcode.c and device.c to walk
6013 through the function call tree and rename the registers so that they
6023 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6030 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6032 Made bitfield a distinct type from bit so that bitfields
6033 convert as per ANSI C and bits retain their traditional
6034 boolean style behaviour. Implemented bitfield support in
6042 * src/ds390/gen.c: bit v bitfield split
6043 * src/z80/gen.c: New support for bitfields
6044 * support/regression/tests/bitfields.c: reenabled z80,
6047 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6049 Rules 246.x, 247.x relate to bitfields, the others speed up
6050 access to xdata mapped I/O devices.
6052 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6054 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6056 Cleaned up genPackBits and genUnpackBits and added two helper
6057 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6058 for literal assignments in genPackBits (thanks to Frieder for
6064 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6066 Fixed bug #748310 (pointer to function type mishandled when the
6067 function name is omitted). Also fixed a SIGSEGV when a function
6068 attribute (reentrant, etc) is used on a non-function or on a
6069 function but misplaced before the parameter list.
6071 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6073 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6096 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6098 Made the constant following the "interrupt" keyword optional. If
6099 omitted, the function will not automatically be given an entry
6100 in the interrupt vector table (similar to #pragma NOIV, but
6101 less syntacticly kludgy). The interrupt number is also now
6102 range checked. Also fixed a bug in the high order bit example

6118 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6120 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6121 be re-activated by defining REDUCE_LITERALS)
6122 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6123 unsigned, but are signed by default
6124 * src/SDCCval.c (constVal): rearranged
6125 * src/SDCCval.c (valMod): preliminary fix
6126 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6578 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6579 the regression tests I'm not brave enough to enable 245.b, 245.c
6580 * doc/sdccman.lyx: added latex preamble for hyperref package.
6581 Using pdflatex this will give you a hyperlinked pdf file with
6582 bookmarks. (prepend '%' before /usepackage if this breaks something)

6598 Applied patch from bug 737905 (renamed yylineo to mylineno):
6605 * src/pic16/pcode.c: Cleaned warnings
6606 * src/pic16/pcodeflow.c: Cleaned warnings
6607 * src/pic16/pcoderegs.c: Cleaned warnings

6620 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6622 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6623 it can be defined with CFLAGS when running configure
6624 * src/SDCCmain.c: fixed compiling + linking with object files
6626 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6629 added --disable-pic16-port
6630 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6631 * src/SDCCmain.c: linkOptions is changed to set *,
6632 added if/endif conditional macros to remove options help
6633 messages from optionsTable when a port is not configured, added
6634 support for the PIc16 port in the ports table, when executing
6635 the compiler with no port specified on command line, a default
6636 port is selected with the new macro DEFAULT_PORT which is
6637 defined in port.h, in setDefaultOptions() linkOptions is removed
6638 from initialization assignment, since now it is a set,
6639 parseCmdLine uses setParseWithComma for linkOptions, in
6640 linkEdit() linkOptions are accessed with new function indexSet()
6641 which returns the i'th item of a set variable. See SDCCset.c, in
6642 linkEdit() when calling buildCmdLine(), added linkOptions as
6643 last argument. Now users can pass arguments to gplink via the
6644 -Wl option, main() uses pic16glue() to glue up pic16 programs
6645 * src/SDCCpeeph.c: various changes to support pic16

6656 * src/pic16/glue.c: commented out some error producing lines
6657 * src/pic16/main.c: __config directives are commented out to stop
6658 gpasm complaining and test the linkage with gplink, _linkCmd and
6659 _asmCmd changed to be more gplink and gpasm friendly
6660 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6661 produced an error when parsed, peep rule 12 is added to utilize
6662 movff, but it is commented out since the pCode does not support
6663 yet a command with 2 address arguments
6665 2003-05-18 <johan AT balder>
6667 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6668 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6692 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6694 2003-05-11 Borut Razem <borut.razem AT siol.net>
6696 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6697 the path of bin directory, so that PATH is the only env. variable, which has to be set
6698 in case of standard installation.
6699 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7728 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7730 * in \sdcc\as\mcs51\ changed these files in order to create an
7731 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7732 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7733 following files to include the previous two files: aslink.dsp,
7734 Makefile.aslink, Makefile.bcc, and Makefile.in.
7736 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7737 .adb instead of .cdb
7739 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7741 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7742 value from option --iram-size.
7744 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7746 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7749 2002-09-18 <wiml AT hhhh.org>
7751 * SDCClrange.h: exposed setFromRange() and setToRange()
7752 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7753 packRegsForAccUse() (bug 542397)
7754 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7755 multiple times and emitting the fetch operations more than once
7756 added aopGetUsesAcc() function to allow binary operators to
7757 fetch their operands in the correct order; made genMinus() emit
7758 compact code for X = LITERAL - Y
7760 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7761 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7762 sprintf() in line 1267.
7764 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7765 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7768 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7769 Changes to aslink (All the changes are marked with 'JCF'):
7771 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7774 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7775 area BSEG. Also moves, if possible, the DATA area down into the internal
7776 ram so more space is available.
7778 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7781 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7782 not bytes. Function summary() which creates a memory usage summary
7783 file with extension .mem. Reports of overlaping stack and small stack
7784 size. If the space for the stack is less than 16 bytes aslink trows a
7787 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7788 the 8051. Option 'y' for memory summary output file.
7790 Changes to sdcc (All the changes are marked with 'JCF'):
7792 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7794 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7795 overlaying area for it (uses RegBankUsed[4]).
7797 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7798 bank zero as used by default. By default aslink locates the stack
7799 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7800 the creation of the .mem file. Delegates the allocation of data area
7801 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7802 the begining of the stack area to aslink.
7804 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7805 glue() in SDCCglue.c creates an area for it.
7807 2002-09-03 Borut Razem <borut.razem AT siol.net>
7808 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7809 sdcc/src/pic/glue.c:
7810 introduced atexit() handler for teporay files removal in case of
7811 errors, assertions, ...
7813 2002-08-29 Borut Razem <borut.razem AT siol.net>
7814 * sdcc/support/cpp2/auto-host_vc_in.h:
7815 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7816 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7817 Maybe there is a similar problem with BORLANDC? It should be checked!
7819 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7820 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7821 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7822 was not executed, and the compiler (cl) launched a warning:
7823 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7825 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7826 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7828 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7835 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7836 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7837 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7838 - added Release configuration in VS projects
7839 - review of compiler an linker options
7840 - VC .exe files are generated in bin_vc directory, not to interfere
7841 with binaries generated from other projects (cygwin, mingw, bcc ...)
7843 * sdcc/src/yacc.dsp: added
7845 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7846 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7847 and insert the version number definitions from .version
7849 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7851 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7858 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7860 2002-08-11 Borut Razem <borut.razem AT siol.net>
7861 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7863 2002-08-10 Borut Razem <borut.razem AT siol.net>
7864 * src/SDCCmain.c (main):
7865 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7866 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7867 The consequence was that some temporary files were not removed.
7870 unification of code in functions tempfilename() and tempfile():
7871 function tempnam() is defined in Visual Studio 6.0 and .NET
7873 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7875 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7876 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7877 - removed compiler command line option /WX: Treats all warnings as errors
7878 - update a list of source files, included into the project
7880 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7881 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7882 changed project type to Generic Project so that can be correcly converted to VS.NET project
7884 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7886 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7890 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7891 added return 0 statements after assert() to make compiler happy
7893 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7894 added newline in the def file to keep MSC compiler satisfied
7896 * sdcc/src/z80/gen.c:
7897 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7898 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7899 - solved MSC error in function aopDump()
7901 * sdcc_vc.h: define PREFIX as "\\sdcc"
7903 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7958 Compiler generated registers for interrupt context saving
7959 were not getting allocated.
7961 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7964 Fixed left shift. Will promote the left side of a left shift
7965 if a) left shifting more than size of operand or b) when assigned
7966 to something size > size of left side
7968 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8078 * sdcc/src/SDCCloop.c:
8079 Previous fix was not good. basic blocks that have "break" or "return" are
8080 not really partof a loop , but live ranges used in these blocks should
8081 be live thru the entire loop, so set partOfLoop but don't add them to
8084 2002-02-21 <johan AT FRIJA>
