643 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
645 * device/lib/printf_large.c: removed inline assembly for portability and
646 readability. Use printf_fast if speed or size are more important.
647 * src/pic16/gen.c: removed conditions around use of DEBUGpc
648 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
650 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
652 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
653 prevent compiler warning
655 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
657 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
658 moved to level 0 and declared as static. Also they are explicit
659 placed in access bank. This was necessery because some times they
660 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
661 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
662 optimizations. Currently only compare to unsigned char is implemented,
663 * src/pic16/gen.c: added fReturnIdx array,
664 * (struct resolvedIfx) is moved to gen.h and made public,
665 * (struct _G): added sregsAlloc and sregsAllocSet fields,
666 * (aopForSym): added an optimization to directly store in stack of
667 the operand of a SEND iCode,
668 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
669 but as registers instead (AOP_REG) using the fReturnIdx array,
670 * (pic16_freeAsmop): remove the freed register from the
672 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
674 * (pic16_popGetTempRegCond): changed function prototype, now
675 function takes also a bitVector argument v which holds the current
676 set of registers that are allocated for stack access by aopForSym,
677 registers allocated in aopForSym for accessing stack symbols are not
678 any more part of the functions usedRegs field,
679 * (genCall): some times aopOp is called for a stack variable to be
680 send, aopForSym might perform the push, if this is true make sure
681 that genCall doesn't push the variable twice by testing _G.resDirect,
682 * (genFunction): changed testing for unspecified interrupt number
683 from 256 to INTNO_UNSPEC,
684 * modified selection scheme of frame pointer generation. Previously
685 if function did use local registers a frame pointer was generated,
686 now a frame pointer is generated only if function has arguments
687 (that need PLUSW2 register access), or has stack arguments, or the
688 compiler is not instructed to omit the frame pointer,
689 * (genEndFunction): before restoring local registers that were saved
690 in the function preamble, also restore the registers that *might*
691 have been allocated for stack access,
692 * (genRet): removed some old comments,
693 * (genCmp, the active (RN's) version): added a call to the
694 pic16_genCmp_special function to perform the compare with a more
695 robust and optimized way,
696 * (genInline): a feature has been added in inline code generation,
697 which allows a wildcard variable substitution when writing inline
698 assembly. Code is incomplete and experimental therefore undocumented,
699 * (genCast): changed order of aopOp for result and right to allow
700 aopForSym to directly load the result if possible,
701 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
702 perform an optimized compare on some selected special occasions,
703 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
704 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
705 generate an IVT any more,
706 * src/pic16/main.c (pic16_optionsTable): added command line option
708 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
709 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
711 * src/pic16/NOTES: Raphael Neider added in list of active developers
712 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
713 jumptable_end to prevent bug #,
714 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
715 inCond and outCond fields,
716 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
717 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
718 turn off register spilling,
719 * (packRegsForOneUse): synced with other ports' versions although it
720 is not used currently,
721 * (pic16_packRegisters): added an optimization while reading
722 structure bitfields, some registers may be saved (malloc code is
723 decreased by 80 bytes)
725 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
727 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
728 left is a bitfield, if yes, then don't optimize assignment. Perhaps
729 this can be optimized more?
731 2005-03-10 Raphael Neider <rneider AT web.de>
733 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
734 genNearPointerGet): (hopefully) fixed access to bitfields via
735 pointers (p->bitN = x; and x = p->bitN; failed)
737 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
739 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1350 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
1352 (setFromConditionArgs): friendly operand parser for peephole rules,
1353 (operandBaseName, operandsNotRelated): new peephole condition
1354 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1355 architecture specific register naming into account, handles n-way
1356 comparisons, and supports quoted literals
1357 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

1367 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1369 Adding support for replacing ljmps with sjmps in jumptables
1370 generated for switch statements. For now you need to set the
1371 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1372 Now 4 algorithms for mcs51 jumptable generation are used:
1373 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1374 addresses loaded pc-relative for up to 112 cases and stack-pushing
1375 target addresses loaded with offset from dptr for up to 256 cases.
1377 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1378 * src/mcs51/main.c: adapted constants for switch table generation
1379 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1401 Large cummulative patch for pic16 port.
1402 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1403 to call when a stack overflow occurs,
1404 * (malloc.h): added CVS Id tag,
1405 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1407 * added libc directory. The current version of LibC contains string
1408 functions, ctype functions and macros and some functions of the
1409 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1410 be extensively tested in the future. Standard disclaimer here.
1411 Library is not automatically build yet. But one can build it by
1412 invoking 'make' inside the libc directory.
1413 * added ADC library under libio. Preliminary version yet.
1415 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1416 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1417 aopForRemat() now and not by pic16_aopOp(),
1418 * (pic16_popGetTempReg): removed warning messgae when allocating
1419 temporary registers, its a buggy feature and will be removed,
1420 * (pic16_popGet): set register instance field in AOP_CRY,
1421 * (pic16_outBitC): fixed for results in size greater than 1,
1422 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1423 * (pic16_storeForReturn): optimized return of 0,
1424 * (genCmp): experimental code for new genCmp which uses PIC18's
1425 special compare&skip instructions. Initial tests fail some times
1426 with variables grater than 1 byte in size, so new code is disabled,
1427 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1429 * (genCast): began a fix to optimize the casting of a bit to another
1430 bit, now assigning a bitfield to another bitfield will fail, sorry,
1431 * src/pic16/main.c: disabled the use of lr-support feature,
1432 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1433 * added some function prototypes, added function _debugf prototype,
1434 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1435 bits with offset (case PO_GPR_BIT),
1436 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1438 * (isBankInstruction): modified to return 0 for no banking instruction,
1439 and 1 for banking instruction,
1440 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1441 caused stop processing pCodes after a inline assembly block,
1442 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1443 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1444 registers when it shouldn't,
1445 * src/pic16/ralloc.c (allocReg): add preliminary support for
1446 supporting a limited set of temporary registers,
1448 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1450 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1451 genDataPointerSet): ensure assignments always copy in MSB to LSB
1453 (loadRegFromAop): recognize CLRH optimization,
1454 (genFunction): optimize RECEIVE iCodes in reentrant functions
1456 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1458 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1459 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1461 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1467 * device/lib/_gptrget.c (_gptrget),
1468 * device/lib/_gptrgetc.c (_gptrgetc),
1469 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1470 instead of sjmp to ret
1471 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1472 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1474 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4444 * src/SDCCval.c (cheapestVal): added missing checks
4445 * src/SDCCicode.c (usualBinaryConversions): fixed condition
4446 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
4448 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
4450 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
4453 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4455 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4456 loaded with the linker search paths (-L arguments) and the libraries
4457 to be linked with the current source (-l arguments). Changes
4458 currently will affect only the pic16 port.
4459 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4460 include path the port specific paths and port specific libraries,
4461 * gplink command now contains the $3 argument,
4462 * src/pic16/device.h,
4463 * src/pic16/device.c,: structure PIC_device is made public and
4464 renamed to PIC16_device, the same for variable Pics which is renamed
4465 to Pics16. Updated all references to them.
4466 * src/pic16/glue.c (pic16glue): corrected bug with code
4467 initialization which bypassed the variable initializations block.
4469 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4470 COMPILE_FLAGS and added the --nostdinc option
4472 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4474 * device/include/mc68hc908jb8.h: Register defs for another member
4475 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4477 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4479 Documenting changes from previous commits.
4480 * configure.in (version 1.56),
4481 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4482 when generating output files to configure the pic16 library,
4483 but now I've commented it out, since gputils aren't installed in the
4484 SF compile farm, so library won't compile
4486 * device/lib/Makefile.in (version 1.56): initially I've added in
4487 target 'all' the prerequestive 'model-pic16' so it compiled the
4488 pic16 library, but now I've commented it out for the same reasons
4490 * added targets 'model-pic16' and 'objects-pic16' to compile the
4492 * added target 'port-specific-objects-pic16' to handle the
4493 generated libraries and copy them into the build/ directory
4494 * added target 'clean-intermediate-pic16' to clean intermediate
4495 files into pic16 directory
4496 * in target 'installdirs' added line to create directory pic16 in
4497 the installation path
4499 * device/include/Makefile.in (version 1.11): in target 'install'
4500 added lines to copy all header files to installation path,
4501 * in target 'installdirs' added line create directory for pic16
4502 headers in the installation path

4517 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4518 option so that it actually works. Made it specific to the z80, since
4519 the gbz80 doesn't have these kinds of I/O ports.
4521 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4523 * device/include/z180.h,

4531 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4532 portmode; added deprecation warning for bank= and protmode= forms.
4533 Also, guard against buffer overflow.
4534 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4536 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4538 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4539 changed interrupt vector table generation to only emit declared vectors.
4540 * device/include/Makefile.in: added missing backslash
4541 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4543 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4545 Mainly changes to support compilation of the device libraries
4546 * src/pic16/device.c: stack is allocated via symbol and not
4547 via literal number. The symbol is placed in the corresponding
4548 position of the data ram
4549 * (pic16_dump_section): relocatable and absolute uninitialized
4550 data are now emitted in sorted order to reduce section naming,
4551 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4552 weren't marked as being in the access bank,
4554 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4556 Added portion of GNU PIC Library under the directory
4557 device/include/pic16 and device/lib/pic16. These files
4558 contain the declarations of SFRs for the PIC18Fxx2 devices.
4559 The directory is initialized via configure from toplevel.
4561 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4563 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4564 the spilllocations to be compared correctly
4566 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4568 * src/SDCCast.c (decorateType): fixed bug introduced today
4570 2004-01-12 Borut Razem <borut.razem AT siol.net>
4572 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4575 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4577 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4578 in simpler and even better code

4586 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4588 * doc/sdccman.lyx: Moved and added some sections, small changes
4589 all over. Telling LaTeX to be less strict with word spacing
4590 to better keep the right margin. Changed some notes about
4591 maintainance of the ports in section 3.2.1 - is it OK like this?
4593 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4630 UPPER for immediate operands,
4631 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4633 * src/pic16/peeph.def: all peepholes with movff are commented out,
4634 because there is a problem in the pcode peep optimizer,
4635 * src/pic16/ralloc.c: the register allocator can now reuse local

4637 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4639 Added file src/pic16/NOTES with information about program writing on
4640 the current port version.

4672 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4675 * src/z80/main.c: added missed needLinkerScript flags (more than
4676 one port structure defined in these file)
4677 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4693 needLinkerScript flag
4695 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4696 * src/pic/glue.c: added variable udata_section_name to
4697 override default uninitialized data segment definition for

4699 * (pic14emitOverlay): modified to emit a commented overlay segment
4700 directive when no overlay data exist
4701 * (picglue): modified to emit uninitialized data segment
4702 according to udata_section_name

4712 2004-01-07 Borut Razem <borut.razem AT siol.net>
4714 * support/scripts/sdcc.nsi: update PATH
4715 * support/scripts/sdcc.ico: craeted
4717 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

4728 include information about variables allocated to the overlay
4731 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4733 * as/mcs51/lkmain.c: Help about -Y option

4745 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4747 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4748 (default behaviour).
4750 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4752 A python script to validate compiler diagnostic messages. It can be
4753 used to verify that sdcc complains about bad c source code and
4754 gives a good location of the error.
4755 * support/valdiag/Makefile,
4756 * support/valdiag/valdiag.py,
4757 * support/valdiag/tests/*
4759 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4772 * src/common.h: added ifndef/define/endif macros
4773 around the header file.
4774 Bug reported from Jesus Calvino-Fraga
4776 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4778 * sdcc.spec: updated
4779 * device/include/Makefile.in: don't install CVS directories
4780 * device/lib/Makefile.in: added removal of CVS directories after install
4781 * doc/Makefile: fixed install, added local_icons
4782 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4783 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4784 * src/ds390/gen.c (genRightShift): fixed bug #870788
4785 * src/SDCCast.c (decorateType): fixed bug #870781
4787 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4789 PIC16 port related changes:
4790 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4791 added variable stackPos,
4793 * gen.c: genCall, assignResultValue: added support for
4794 pushing/retrieving function parameters to/from stack,
4795 genFunction,genEndFunction: setup stack frame for the
4797 genAddrOf: will be changed according to bug 863624
4799 * added files genutils.c and genutils.h which contain gen*
4800 debugged and optimised functions extracted from gen.c
4802 * glue.c: added variable 'externs' which holds extern symbols,
4803 pic16emitRegularMap: is modified to properly handle relocatable
4804 symbols under the new scheme,
4805 pic16createInterruptVect: is modified
4806 pic16printPublics: is modified to emit 'global' assembler directives,
4807 added pic16_printExterns to print extern symbols,
4808 pic16glue: initializes stack/frame pointer in the beginning of
4809 the assembly output. Temporary hack, will be corrected later,
4810 because gplink yet does not support stack and SDCC does not
4811 yet support a type of crt0.o object to create the final binary.
4813 * Removed many lines that contain 8051 legacy code.
4814 * The code is finally placed under a 'code' directive.
4815 * Added port specific options.
4817 * _process_pragma: simplified since now we do not need *special*
4818 include file to define SFR registers. But a separate header
4819 will be needed. This will be developed later.
4820 * _pic16_parseOptions: added, parses port specific options:
4821 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4822 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4823 --preplace-udata-with=
4825 * _pic16_setDefaultOptions: modified to initialize section names,
4826 but hack is temporarly out of order since it needs improvement.
4827 * _pic16_genAssemblerPreamble: configuration words are emitted by
4828 their address instead of their name. This part is incomplete and
4829 supports only the 18Fxx2 devices. Other devices will emit an error
4830 during assembly since they do not contain the same set of config
4832 * _pic16_genIVT: is modified,
4834 * pcode.c: added definitions for some hardware registers that are needed
4836 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4837 All PCI entries are updated. Now LFSR is supported.
4838 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4839 * added pic16_newpCodeOpLit2 to support instructions with
4840 two literal arguments
4841 * pic16_pCode2str: corrected code that emits assembler instructions
4842 with two literal operands and those that have an access bit modifier
4843 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4844 this fixes a bug which caused some labels to be lost, when an
4845 assembler directive was added, i.e. banksel,
4846 * pic16_FixRegisterBanking: improved logic that causes the insertion
4848 * InlineFunction: functions that are called once, are not any more
4849 inlined. This can be a port option in the future,
4851 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4853 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4854 hold the corresponding uninitialized symbols,
4855 * pic16_allocProcessorRegister: registers have explicit marked the
4857 * pic16_allocInternalRegister: registers are explicit marked as
4859 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4860 processing list, so bit registers were lost,
4863 * ralloc.h: added field 'accessBank' and original symbol operand
4864 in register definition,
4865 * removed the field isMapped from register definition,
4867 ** Several functions have been removed from various sources:
4868 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4869 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4870 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4871 pic16_assignRelocatableRegisters
4873 ** others have been introduced:
4874 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4875 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4877 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4879 * support/scripts/inc2h.pl: changed definition of BIT_AT
4880 to emit 'sbit at' instead of 'bit at'. This was a request.
4882 PIC16 port related preliminary changes:
4883 * gen.c: prefixed function popRegFromString with
4884 pic16_ and all references to it corrected
4885 * pcode.c: all pic16_pc_* hardware registers prefixed
4886 with underscore (_),
4887 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4888 * ralloc.c: newReg(): when register is REG_SFR then
4889 set address to rIdx,
4890 pic16_allocProcessorRegister(): marks register wasUsed=0
4891 pic16_writeUsedRegs(): added a call to assign processor
4892 registers via pic16_assignFixedRegisters
4894 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4896 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4897 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4898 variables in unused register banks. Also the SSEG is placed
4899 wherever there is enough space for it, and IDATA can be anywhere
4900 in internal RAM. For now compile using -Wl-Y[stack_size].
4901 The mem file is different for this option as well, since it
4902 makes no sense of talking about DSEG lenght.
4904 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4906 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4907 in certain cases, e.g. when ROM assignment, patch provided
4908 from Albert den Haan.
4910 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5929 these ports have their own __sdcc_external_start()
5931 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5933 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5934 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5935 type for bits was changed. It resulted in bit variables becoming
5936 global, which is not permitted in PIC 14 assembly output.
5938 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5940 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5953 A few small changes that speed up the peephole optimizer.
5957 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5959 Try to make the peephole optimizer smarter by maintaining
5960 an association between the assembly source code and the
5961 iCodes that originated them. Put this information to use
5962 with a new peephole rule condition "notVolatile" so that
5963 the rules can be aggressive yet still safe.
5968 * src/mcs51/peeph.def
5970 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5974 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5975 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5976 if the left or right operand symbols have the accuse flag set.
5978 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5980 Changed the type of the result of the ! (NOT) operator to char;
5981 previously it returned the same type as the source. This allows
5982 us to eliminate all the genFloatNot functions (all of its target
5983 implementations were very buggy) since !float can use the same
5986 * src/SDCCicode.c (ast2iCode): ! returns char

5995 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5996 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5997 during interrupts. Ensure WSAVE is located at a shared bank address.
5998 2. Fixed page selection in some places
5999 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6000 the registers name strings.
6001 4. Fixed "signed / unsigned compare" compiler warnings.
6002 5. The PIC port manages its own allocation of the general purpose
6003 registers, but makes no attempt to reuse them. As a result when
6004 compiling it soon runs out of general purpose registers. Some
6005 additional code was added to the files pcode.c and device.c to walk
6006 through the function call tree and rename the registers so that they
6016 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6023 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6025 Made bitfield a distinct type from bit so that bitfields
6026 convert as per ANSI C and bits retain their traditional
6027 boolean style behaviour. Implemented bitfield support in
6035 * src/ds390/gen.c: bit v bitfield split
6036 * src/z80/gen.c: New support for bitfields
6037 * support/regression/tests/bitfields.c: reenabled z80,
6040 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6042 Rules 246.x, 247.x relate to bitfields, the others speed up
6043 access to xdata mapped I/O devices.
6045 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6047 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6049 Cleaned up genPackBits and genUnpackBits and added two helper
6050 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6051 for literal assignments in genPackBits (thanks to Frieder for
6057 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6059 Fixed bug #748310 (pointer to function type mishandled when the
6060 function name is omitted). Also fixed a SIGSEGV when a function
6061 attribute (reentrant, etc) is used on a non-function or on a
6062 function but misplaced before the parameter list.
6064 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6066 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6089 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6091 Made the constant following the "interrupt" keyword optional. If
6092 omitted, the function will not automatically be given an entry
6093 in the interrupt vector table (similar to #pragma NOIV, but
6094 less syntacticly kludgy). The interrupt number is also now
6095 range checked. Also fixed a bug in the high order bit example

6116 unsigned, but are signed by default
6117 * src/SDCCval.c (constVal): rearranged
6118 * src/SDCCval.c (valMod): preliminary fix
6119 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6613 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6615 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6616 it can be defined with CFLAGS when running configure
6617 * src/SDCCmain.c: fixed compiling + linking with object files
6619 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6621 * configure.in: configure for pic16 port,
6622 added --disable-pic16-port
6623 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6624 * src/SDCCmain.c: linkOptions is changed to set *,
6625 added if/endif conditional macros to remove options help
6626 messages from optionsTable when a port is not configured, added
6627 support for the PIc16 port in the ports table, when executing
6628 the compiler with no port specified on command line, a default
6629 port is selected with the new macro DEFAULT_PORT which is
6630 defined in port.h, in setDefaultOptions() linkOptions is removed
6631 from initialization assignment, since now it is a set,
6632 parseCmdLine uses setParseWithComma for linkOptions, in
6633 linkEdit() linkOptions are accessed with new function indexSet()
6634 which returns the i'th item of a set variable. See SDCCset.c, in
6635 linkEdit() when calling buildCmdLine(), added linkOptions as
6636 last argument. Now users can pass arguments to gplink via the
6637 -Wl option, main() uses pic16glue() to glue up pic16 programs
6638 * src/SDCCpeeph.c: various changes to support pic16
6639 * src/SDCCset.c: added function void *indexSet(set *, int) to

6645 added macro DEFAULT_PORT
6646 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
6647 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6649 * src/pic16/glue.c: commented out some error producing lines
6650 * src/pic16/main.c: __config directives are commented out to stop
6651 gpasm complaining and test the linkage with gplink, _linkCmd and
6652 _asmCmd changed to be more gplink and gpasm friendly
6653 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6654 produced an error when parsed, peep rule 12 is added to utilize
6655 movff, but it is commented out since the pCode does not support
6656 yet a command with 2 address arguments
6658 2003-05-18 <johan AT balder>
6660 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6661 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6680 on entry now. Add tbreak. Other enhancements and fixes for use
6683 2003-05-12 Borut Razem <borut.razem AT siol.net>
6685 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6687 2003-05-11 Borut Razem <borut.razem AT siol.net>
6689 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6690 the path of bin directory, so that PATH is the only env. variable, which has to be set
6691 in case of standard installation.
6692 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7721 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7723 * in \sdcc\as\mcs51\ changed these files in order to create an
7724 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7725 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7726 following files to include the previous two files: aslink.dsp,
7727 Makefile.aslink, Makefile.bcc, and Makefile.in.
7729 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7730 .adb instead of .cdb
7732 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7734 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7735 value from option --iram-size.
7737 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7739 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7742 2002-09-18 <wiml AT hhhh.org>
7744 * SDCClrange.h: exposed setFromRange() and setToRange()
7745 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7746 packRegsForAccUse() (bug 542397)
7747 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7748 multiple times and emitting the fetch operations more than once
7749 added aopGetUsesAcc() function to allow binary operators to
7750 fetch their operands in the correct order; made genMinus() emit
7751 compact code for X = LITERAL - Y
7753 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7754 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7755 sprintf() in line 1267.
7757 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7758 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7761 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7762 Changes to aslink (All the changes are marked with 'JCF'):
7764 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7767 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7768 area BSEG. Also moves, if possible, the DATA area down into the internal
7769 ram so more space is available.
7771 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7774 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7775 not bytes. Function summary() which creates a memory usage summary
7776 file with extension .mem. Reports of overlaping stack and small stack
7777 size. If the space for the stack is less than 16 bytes aslink trows a
7780 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7781 the 8051. Option 'y' for memory summary output file.
7783 Changes to sdcc (All the changes are marked with 'JCF'):
7785 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7787 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7788 overlaying area for it (uses RegBankUsed[4]).
7790 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7791 bank zero as used by default. By default aslink locates the stack
7792 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7793 the creation of the .mem file. Delegates the allocation of data area
7794 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7795 the begining of the stack area to aslink.
7797 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7798 glue() in SDCCglue.c creates an area for it.
7800 2002-09-03 Borut Razem <borut.razem AT siol.net>
7801 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7802 sdcc/src/pic/glue.c:
7803 introduced atexit() handler for teporay files removal in case of
7804 errors, assertions, ...
7806 2002-08-29 Borut Razem <borut.razem AT siol.net>
7807 * sdcc/support/cpp2/auto-host_vc_in.h:
7808 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7809 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7810 Maybe there is a similar problem with BORLANDC? It should be checked!
7812 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7813 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7814 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7815 was not executed, and the compiler (cl) launched a warning:
7816 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7818 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

7831 - added Release configuration in VS projects
7832 - review of compiler an linker options
7833 - VC .exe files are generated in bin_vc directory, not to interfere
7834 with binaries generated from other projects (cygwin, mingw, bcc ...)
7836 * sdcc/src/yacc.dsp: added
7838 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7839 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7840 and insert the version number definitions from .version
7842 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7844 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7853 2002-08-11 Borut Razem <borut.razem AT siol.net>
7854 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7856 2002-08-10 Borut Razem <borut.razem AT siol.net>
7857 * src/SDCCmain.c (main):
7858 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7859 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7860 The consequence was that some temporary files were not removed.
7863 unification of code in functions tempfilename() and tempfile():
7864 function tempnam() is defined in Visual Studio 6.0 and .NET
7866 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7868 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7869 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7870 - removed compiler command line option /WX: Treats all warnings as errors
7871 - update a list of source files, included into the project
7873 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7874 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7875 changed project type to Generic Project so that can be correcly converted to VS.NET project
7877 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7879 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7883 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7884 added return 0 statements after assert() to make compiler happy
7886 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7887 added newline in the def file to keep MSC compiler satisfied
7889 * sdcc/src/z80/gen.c:
7890 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7891 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7892 - solved MSC error in function aopDump()
7894 * sdcc_vc.h: define PREFIX as "\\sdcc"
7896 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7951 Compiler generated registers for interrupt context saving
7952 were not getting allocated.
7954 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7957 Fixed left shift. Will promote the left side of a left shift
7958 if a) left shifting more than size of operand or b) when assigned
7959 to something size > size of left side
7961 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8071 * sdcc/src/SDCCloop.c:
8072 Previous fix was not good. basic blocks that have "break" or "return" are
8073 not really partof a loop , but live ranges used in these blocks should
8074 be live thru the entire loop, so set partOfLoop but don't add them to
8077 2002-02-21 <johan AT FRIJA>

8921 2001-09-02 Michael Hope <michaelh AT juju.net.nz>
8923 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
8925 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
8927 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
8929 * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs. Had to shift some functions about to do it.
8931 2001-09-01 Michael Hope <michaelh AT juju.net.nz>
8933 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
8934 (genCmp): Fixed up genCmp for the GB with longs.
8936 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
8938 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
8940 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
8942 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

8946 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
8948 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
8950 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
8952 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
8954 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
8956 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
8958 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
