638 * device/lib/printf_large.c: removed inline assembly for portability and
639 readability. Use printf_fast if speed or size are more important.
640 * src/pic16/gen.c: removed conditions around use of DEBUGpc
641 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
643 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
645 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
646 prevent compiler warning
648 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
650 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
651 moved to level 0 and declared as static. Also they are explicit
652 placed in access bank. This was necessery because some times they
653 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
654 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
655 optimizations. Currently only compare to unsigned char is implemented,
656 * src/pic16/gen.c: added fReturnIdx array,
657 * (struct resolvedIfx) is moved to gen.h and made public,
658 * (struct _G): added sregsAlloc and sregsAllocSet fields,
659 * (aopForSym): added an optimization to directly store in stack of
660 the operand of a SEND iCode,
661 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
662 but as registers instead (AOP_REG) using the fReturnIdx array,
663 * (pic16_freeAsmop): remove the freed register from the
665 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
667 * (pic16_popGetTempRegCond): changed function prototype, now
668 function takes also a bitVector argument v which holds the current
669 set of registers that are allocated for stack access by aopForSym,
670 registers allocated in aopForSym for accessing stack symbols are not
671 any more part of the functions usedRegs field,
672 * (genCall): some times aopOp is called for a stack variable to be
673 send, aopForSym might perform the push, if this is true make sure
674 that genCall doesn't push the variable twice by testing _G.resDirect,
675 * (genFunction): changed testing for unspecified interrupt number
676 from 256 to INTNO_UNSPEC,
677 * modified selection scheme of frame pointer generation. Previously
678 if function did use local registers a frame pointer was generated,
679 now a frame pointer is generated only if function has arguments
680 (that need PLUSW2 register access), or has stack arguments, or the
681 compiler is not instructed to omit the frame pointer,
682 * (genEndFunction): before restoring local registers that were saved
683 in the function preamble, also restore the registers that *might*
684 have been allocated for stack access,
685 * (genRet): removed some old comments,
686 * (genCmp, the active (RN's) version): added a call to the
687 pic16_genCmp_special function to perform the compare with a more
688 robust and optimized way,
689 * (genInline): a feature has been added in inline code generation,
690 which allows a wildcard variable substitution when writing inline
691 assembly. Code is incomplete and experimental therefore undocumented,
692 * (genCast): changed order of aopOp for result and right to allow
693 aopForSym to directly load the result if possible,
694 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
695 perform an optimized compare on some selected special occasions,
696 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
697 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
698 generate an IVT any more,
699 * src/pic16/main.c (pic16_optionsTable): added command line option
701 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
702 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
704 * src/pic16/NOTES: Raphael Neider added in list of active developers
705 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
706 jumptable_end to prevent bug #,
707 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
708 inCond and outCond fields,
709 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
710 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
711 turn off register spilling,
712 * (packRegsForOneUse): synced with other ports' versions although it
713 is not used currently,
714 * (pic16_packRegisters): added an optimization while reading
715 structure bitfields, some registers may be saved (malloc code is
716 decreased by 80 bytes)
718 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
720 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
721 left is a bitfield, if yes, then don't optimize assignment. Perhaps
722 this can be optimized more?
724 2005-03-10 Raphael Neider <rneider AT web.de>
726 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
727 genNearPointerGet): (hopefully) fixed access to bitfields via
728 pointers (p->bitN = x; and x = p->bitN; failed)
730 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
732 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1341 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1343 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
1345 (setFromConditionArgs): friendly operand parser for peephole rules,
1346 (operandBaseName, operandsNotRelated): new peephole condition
1347 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1348 architecture specific register naming into account, handles n-way
1349 comparisons, and supports quoted literals
1350 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
1352 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1360 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1362 Adding support for replacing ljmps with sjmps in jumptables
1363 generated for switch statements. For now you need to set the
1364 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1365 Now 4 algorithms for mcs51 jumptable generation are used:
1366 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1367 addresses loaded pc-relative for up to 112 cases and stack-pushing
1368 target addresses loaded with offset from dptr for up to 256 cases.
1370 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1371 * src/mcs51/main.c: adapted constants for switch table generation
1372 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1394 Large cummulative patch for pic16 port.
1395 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1396 to call when a stack overflow occurs,
1397 * (malloc.h): added CVS Id tag,
1398 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1400 * added libc directory. The current version of LibC contains string
1401 functions, ctype functions and macros and some functions of the
1402 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1403 be extensively tested in the future. Standard disclaimer here.
1404 Library is not automatically build yet. But one can build it by
1405 invoking 'make' inside the libc directory.
1406 * added ADC library under libio. Preliminary version yet.
1408 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1409 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1410 aopForRemat() now and not by pic16_aopOp(),

1412 temporary registers, its a buggy feature and will be removed,
1413 * (pic16_popGet): set register instance field in AOP_CRY,
1414 * (pic16_outBitC): fixed for results in size greater than 1,
1415 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1416 * (pic16_storeForReturn): optimized return of 0,
1417 * (genCmp): experimental code for new genCmp which uses PIC18's
1418 special compare&skip instructions. Initial tests fail some times
1419 with variables grater than 1 byte in size, so new code is disabled,
1420 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1422 * (genCast): began a fix to optimize the casting of a bit to another
1423 bit, now assigning a bitfield to another bitfield will fail, sorry,
1424 * src/pic16/main.c: disabled the use of lr-support feature,
1425 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1426 * added some function prototypes, added function _debugf prototype,
1427 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1428 bits with offset (case PO_GPR_BIT),
1429 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1431 * (isBankInstruction): modified to return 0 for no banking instruction,
1432 and 1 for banking instruction,
1433 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1434 caused stop processing pCodes after a inline assembly block,
1435 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1436 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1437 registers when it shouldn't,
1438 * src/pic16/ralloc.c (allocReg): add preliminary support for
1439 supporting a limited set of temporary registers,
1441 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1443 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1444 genDataPointerSet): ensure assignments always copy in MSB to LSB
1446 (loadRegFromAop): recognize CLRH optimization,
1447 (genFunction): optimize RECEIVE iCodes in reentrant functions
1449 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1451 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1452 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1454 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1456 contiguous with data
1458 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1460 * device/lib/_gptrget.c (_gptrget),
1461 * device/lib/_gptrgetc.c (_gptrgetc),
1462 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1463 instead of sjmp to ret
1464 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1465 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1467 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4443 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
4446 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4448 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4449 loaded with the linker search paths (-L arguments) and the libraries
4450 to be linked with the current source (-l arguments). Changes
4451 currently will affect only the pic16 port.
4452 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4453 include path the port specific paths and port specific libraries,
4454 * gplink command now contains the $3 argument,
4455 * src/pic16/device.h,
4456 * src/pic16/device.c,: structure PIC_device is made public and
4457 renamed to PIC16_device, the same for variable Pics which is renamed
4458 to Pics16. Updated all references to them.
4459 * src/pic16/glue.c (pic16glue): corrected bug with code
4460 initialization which bypassed the variable initializations block.
4462 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4463 COMPILE_FLAGS and added the --nostdinc option
4465 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4467 * device/include/mc68hc908jb8.h: Register defs for another member
4468 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4470 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4472 Documenting changes from previous commits.
4473 * configure.in (version 1.56),
4474 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4475 when generating output files to configure the pic16 library,
4476 but now I've commented it out, since gputils aren't installed in the
4477 SF compile farm, so library won't compile
4479 * device/lib/Makefile.in (version 1.56): initially I've added in
4480 target 'all' the prerequestive 'model-pic16' so it compiled the
4481 pic16 library, but now I've commented it out for the same reasons
4483 * added targets 'model-pic16' and 'objects-pic16' to compile the
4485 * added target 'port-specific-objects-pic16' to handle the
4486 generated libraries and copy them into the build/ directory
4487 * added target 'clean-intermediate-pic16' to clean intermediate
4488 files into pic16 directory
4489 * in target 'installdirs' added line to create directory pic16 in
4490 the installation path
4492 * device/include/Makefile.in (version 1.11): in target 'install'
4493 added lines to copy all header files to installation path,
4494 * in target 'installdirs' added line create directory for pic16
4495 headers in the installation path

4510 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4511 option so that it actually works. Made it specific to the z80, since
4512 the gbz80 doesn't have these kinds of I/O ports.
4514 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4516 * device/include/z180.h,

4529 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4531 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4532 changed interrupt vector table generation to only emit declared vectors.
4533 * device/include/Makefile.in: added missing backslash
4534 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4536 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4538 Mainly changes to support compilation of the device libraries
4539 * src/pic16/device.c: stack is allocated via symbol and not
4540 via literal number. The symbol is placed in the corresponding
4541 position of the data ram
4542 * (pic16_dump_section): relocatable and absolute uninitialized
4543 data are now emitted in sorted order to reduce section naming,
4544 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4545 weren't marked as being in the access bank,
4547 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4549 Added portion of GNU PIC Library under the directory
4550 device/include/pic16 and device/lib/pic16. These files
4551 contain the declarations of SFRs for the PIC18Fxx2 devices.
4552 The directory is initialized via configure from toplevel.
4554 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4556 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4557 the spilllocations to be compared correctly
4559 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4561 * src/SDCCast.c (decorateType): fixed bug introduced today
4563 2004-01-12 Borut Razem <borut.razem AT siol.net>
4565 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4568 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4570 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4571 in simpler and even better code
4573 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4575 * src/SDCCicode.c (operandOperation): fixed bug #874819

4579 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4581 * doc/sdccman.lyx: Moved and added some sections, small changes
4582 all over. Telling LaTeX to be less strict with word spacing
4583 to better keep the right margin. Changed some notes about
4584 maintainance of the ports in section 3.2.1 - is it OK like this?
4586 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4622 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4623 UPPER for immediate operands,
4624 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4626 * src/pic16/peeph.def: all peepholes with movff are commented out,
4627 because there is a problem in the pcode peep optimizer,
4628 * src/pic16/ralloc.c: the register allocator can now reuse local

4630 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4632 Added file src/pic16/NOTES with information about program writing on
4633 the current port version.

4642 * src/SDCCmain.c : fixed #872250: -l command line defined library
4643 files are scanned before standard library files
4645 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4665 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4668 * src/z80/main.c: added missed needLinkerScript flags (more than
4669 one port structure defined in these file)
4670 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4686 needLinkerScript flag
4688 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4689 * src/pic/glue.c: added variable udata_section_name to
4690 override default uninitialized data segment definition for
4691 devices only with SHAREBANK memory (reported from Erik Epetrich)
4692 * (pic14emitOverlay): modified to emit a commented overlay segment
4693 directive when no overlay data exist
4694 * (picglue): modified to emit uninitialized data segment
4695 according to udata_section_name

4701 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4702 object file from '.rel' to '.o' in port->linker structure,
4703 changed size of fptr from 2 to 3 in port structure
4705 2004-01-07 Borut Razem <borut.razem AT siol.net>
4707 * support/scripts/sdcc.nsi: update PATH
4708 * support/scripts/sdcc.ico: craeted
4710 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

4713 * doc/Makefile: fix install
4715 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4717 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4719 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4721 include information about variables allocated to the overlay
4724 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4726 * as/mcs51/lkmain.c: Help about -Y option

4736 LEFT_OP (left shift)
4738 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4740 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4741 (default behaviour).
4743 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4745 A python script to validate compiler diagnostic messages. It can be
4746 used to verify that sdcc complains about bad c source code and
4747 gives a good location of the error.
4748 * support/valdiag/Makefile,
4749 * support/valdiag/valdiag.py,
4750 * support/valdiag/tests/*
4752 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4754 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4755 * src/SDCCsymt.c (newEnumType),

4763 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4765 * src/common.h: added ifndef/define/endif macros
4766 around the header file.
4767 Bug reported from Jesus Calvino-Fraga
4769 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4771 * sdcc.spec: updated
4772 * device/include/Makefile.in: don't install CVS directories
4773 * device/lib/Makefile.in: added removal of CVS directories after install
4774 * doc/Makefile: fixed install, added local_icons
4775 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4776 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4777 * src/ds390/gen.c (genRightShift): fixed bug #870788
4778 * src/SDCCast.c (decorateType): fixed bug #870781
4780 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4782 PIC16 port related changes:
4783 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4784 added variable stackPos,
4786 * gen.c: genCall, assignResultValue: added support for
4787 pushing/retrieving function parameters to/from stack,
4788 genFunction,genEndFunction: setup stack frame for the
4790 genAddrOf: will be changed according to bug 863624
4792 * added files genutils.c and genutils.h which contain gen*
4793 debugged and optimised functions extracted from gen.c
4795 * glue.c: added variable 'externs' which holds extern symbols,
4796 pic16emitRegularMap: is modified to properly handle relocatable
4797 symbols under the new scheme,
4798 pic16createInterruptVect: is modified
4799 pic16printPublics: is modified to emit 'global' assembler directives,
4800 added pic16_printExterns to print extern symbols,
4801 pic16glue: initializes stack/frame pointer in the beginning of
4802 the assembly output. Temporary hack, will be corrected later,
4803 because gplink yet does not support stack and SDCC does not
4804 yet support a type of crt0.o object to create the final binary.
4806 * Removed many lines that contain 8051 legacy code.
4807 * The code is finally placed under a 'code' directive.
4808 * Added port specific options.
4810 * _process_pragma: simplified since now we do not need *special*
4811 include file to define SFR registers. But a separate header
4812 will be needed. This will be developed later.
4813 * _pic16_parseOptions: added, parses port specific options:
4814 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4815 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4816 --preplace-udata-with=
4818 * _pic16_setDefaultOptions: modified to initialize section names,
4819 but hack is temporarly out of order since it needs improvement.
4820 * _pic16_genAssemblerPreamble: configuration words are emitted by
4821 their address instead of their name. This part is incomplete and
4822 supports only the 18Fxx2 devices. Other devices will emit an error
4823 during assembly since they do not contain the same set of config
4825 * _pic16_genIVT: is modified,
4827 * pcode.c: added definitions for some hardware registers that are needed
4829 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4830 All PCI entries are updated. Now LFSR is supported.
4831 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4832 * added pic16_newpCodeOpLit2 to support instructions with
4833 two literal arguments
4834 * pic16_pCode2str: corrected code that emits assembler instructions
4835 with two literal operands and those that have an access bit modifier
4836 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4837 this fixes a bug which caused some labels to be lost, when an
4838 assembler directive was added, i.e. banksel,
4839 * pic16_FixRegisterBanking: improved logic that causes the insertion
4841 * InlineFunction: functions that are called once, are not any more
4842 inlined. This can be a port option in the future,
4844 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4846 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4847 hold the corresponding uninitialized symbols,
4848 * pic16_allocProcessorRegister: registers have explicit marked the
4850 * pic16_allocInternalRegister: registers are explicit marked as
4852 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4853 processing list, so bit registers were lost,
4856 * ralloc.h: added field 'accessBank' and original symbol operand
4857 in register definition,
4858 * removed the field isMapped from register definition,
4860 ** Several functions have been removed from various sources:
4861 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4862 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4863 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4864 pic16_assignRelocatableRegisters
4866 ** others have been introduced:
4867 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4868 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4870 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4872 * support/scripts/inc2h.pl: changed definition of BIT_AT
4873 to emit 'sbit at' instead of 'bit at'. This was a request.
4875 PIC16 port related preliminary changes:
4876 * gen.c: prefixed function popRegFromString with
4877 pic16_ and all references to it corrected
4878 * pcode.c: all pic16_pc_* hardware registers prefixed
4879 with underscore (_),
4880 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4881 * ralloc.c: newReg(): when register is REG_SFR then
4882 set address to rIdx,
4883 pic16_allocProcessorRegister(): marks register wasUsed=0
4884 pic16_writeUsedRegs(): added a call to assign processor
4885 registers via pic16_assignFixedRegisters
4887 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4889 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4890 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4891 variables in unused register banks. Also the SSEG is placed
4892 wherever there is enough space for it, and IDATA can be anywhere
4893 in internal RAM. For now compile using -Wl-Y[stack_size].
4894 The mem file is different for this option as well, since it
4895 makes no sense of talking about DSEG lenght.
4897 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4899 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4900 in certain cases, e.g. when ROM assignment, patch provided
4901 from Albert den Haan.
4903 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5921 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
5922 these ports have their own __sdcc_external_start()
5924 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5926 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5927 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5928 type for bits was changed. It resulted in bit variables becoming
5929 global, which is not permitted in PIC 14 assembly output.
5931 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5933 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5935 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5937 Z80 and MCS51 linkers complaint if a public symbol is defined

5946 A few small changes that speed up the peephole optimizer.
5950 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5952 Try to make the peephole optimizer smarter by maintaining
5953 an association between the assembly source code and the
5954 iCodes that originated them. Put this information to use
5955 with a new peephole rule condition "notVolatile" so that
5956 the rules can be aggressive yet still safe.
5961 * src/mcs51/peeph.def
5963 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5967 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5968 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5969 if the left or right operand symbols have the accuse flag set.
5971 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5973 Changed the type of the result of the ! (NOT) operator to char;
5974 previously it returned the same type as the source. This allows
5975 us to eliminate all the genFloatNot functions (all of its target
5976 implementations were very buggy) since !float can use the same
5979 * src/SDCCicode.c (ast2iCode): ! returns char

5988 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5989 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5990 during interrupts. Ensure WSAVE is located at a shared bank address.
5991 2. Fixed page selection in some places
5992 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5993 the registers name strings.
5994 4. Fixed "signed / unsigned compare" compiler warnings.
5995 5. The PIC port manages its own allocation of the general purpose
5996 registers, but makes no attempt to reuse them. As a result when
5997 compiling it soon runs out of general purpose registers. Some
5998 additional code was added to the files pcode.c and device.c to walk
5999 through the function call tree and rename the registers so that they
6009 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6010 genPlus() & genMinus() when the result is the same as left or right

6016 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6018 Made bitfield a distinct type from bit so that bitfields
6019 convert as per ANSI C and bits retain their traditional
6020 boolean style behaviour. Implemented bitfield support in
6028 * src/ds390/gen.c: bit v bitfield split
6029 * src/z80/gen.c: New support for bitfields
6030 * support/regression/tests/bitfields.c: reenabled z80,
6033 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6035 Rules 246.x, 247.x relate to bitfields, the others speed up
6036 access to xdata mapped I/O devices.
6038 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6040 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6042 Cleaned up genPackBits and genUnpackBits and added two helper
6043 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6044 for literal assignments in genPackBits (thanks to Frieder for
6050 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6052 Fixed bug #748310 (pointer to function type mishandled when the
6053 function name is omitted). Also fixed a SIGSEGV when a function
6054 attribute (reentrant, etc) is used on a non-function or on a
6055 function but misplaced before the parameter list.
6057 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6059 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6060 * support/Util/SDCCerr.h,
6061 * support/Util/SDCCerr.c: Added func attr misuse error msg

6082 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6084 Made the constant following the "interrupt" keyword optional. If
6085 omitted, the function will not automatically be given an entry
6086 in the interrupt vector table (similar to #pragma NOIV, but
6087 less syntacticly kludgy). The interrupt number is also now
6088 range checked. Also fixed a bug in the high order bit example

6104 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6106 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6107 be re-activated by defining REDUCE_LITERALS)
6108 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6109 unsigned, but are signed by default
6110 * src/SDCCval.c (constVal): rearranged
6111 * src/SDCCval.c (valMod): preliminary fix
6112 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6535 for a non-native english speaker.
6536 Please feel free to add to the manual or to correct my changes.

6564 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6565 the regression tests I'm not brave enough to enable 245.b, 245.c
6566 * doc/sdccman.lyx: added latex preamble for hyperref package.
6567 Using pdflatex this will give you a hyperlinked pdf file with
6568 bookmarks. (prepend '%' before /usepackage if this breaks something)

6584 Applied patch from bug 737905 (renamed yylineo to mylineno):
6591 * src/pic16/pcode.c: Cleaned warnings
6592 * src/pic16/pcodeflow.c: Cleaned warnings
6593 * src/pic16/pcoderegs.c: Cleaned warnings

6606 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6608 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6609 it can be defined with CFLAGS when running configure
6610 * src/SDCCmain.c: fixed compiling + linking with object files
6612 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6614 * configure.in: configure for pic16 port,
6615 added --disable-pic16-port
6616 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6617 * src/SDCCmain.c: linkOptions is changed to set *,
6618 added if/endif conditional macros to remove options help
6619 messages from optionsTable when a port is not configured, added
6620 support for the PIc16 port in the ports table, when executing
6621 the compiler with no port specified on command line, a default
6622 port is selected with the new macro DEFAULT_PORT which is
6623 defined in port.h, in setDefaultOptions() linkOptions is removed
6624 from initialization assignment, since now it is a set,
6625 parseCmdLine uses setParseWithComma for linkOptions, in
6626 linkEdit() linkOptions are accessed with new function indexSet()
6627 which returns the i'th item of a set variable. See SDCCset.c, in
6628 linkEdit() when calling buildCmdLine(), added linkOptions as
6629 last argument. Now users can pass arguments to gplink via the
6630 -Wl option, main() uses pic16glue() to glue up pic16 programs
6631 * src/SDCCpeeph.c: various changes to support pic16

6640 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6642 * src/pic16/glue.c: commented out some error producing lines
6643 * src/pic16/main.c: __config directives are commented out to stop
6644 gpasm complaining and test the linkage with gplink, _linkCmd and
6645 _asmCmd changed to be more gplink and gpasm friendly
6646 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6647 produced an error when parsed, peep rule 12 is added to utilize
6648 movff, but it is commented out since the pCode does not support
6649 yet a command with 2 address arguments
6651 2003-05-18 <johan AT balder>
6653 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6654 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6673 on entry now. Add tbreak. Other enhancements and fixes for use
6676 2003-05-12 Borut Razem <borut.razem AT siol.net>
6678 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6680 2003-05-11 Borut Razem <borut.razem AT siol.net>
6682 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6683 the path of bin directory, so that PATH is the only env. variable, which has to be set
6684 in case of standard installation.
6685 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7714 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7716 * in \sdcc\as\mcs51\ changed these files in order to create an
7717 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7718 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7719 following files to include the previous two files: aslink.dsp,
7720 Makefile.aslink, Makefile.bcc, and Makefile.in.
7722 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7723 .adb instead of .cdb
7725 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7727 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7728 value from option --iram-size.
7730 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7732 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7735 2002-09-18 <wiml AT hhhh.org>
7737 * SDCClrange.h: exposed setFromRange() and setToRange()
7738 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7739 packRegsForAccUse() (bug 542397)
7740 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7741 multiple times and emitting the fetch operations more than once
7742 added aopGetUsesAcc() function to allow binary operators to
7743 fetch their operands in the correct order; made genMinus() emit
7744 compact code for X = LITERAL - Y
7746 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7747 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7748 sprintf() in line 1267.
7750 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7751 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7754 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7755 Changes to aslink (All the changes are marked with 'JCF'):
7757 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7760 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7761 area BSEG. Also moves, if possible, the DATA area down into the internal
7762 ram so more space is available.
7764 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7767 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7768 not bytes. Function summary() which creates a memory usage summary
7769 file with extension .mem. Reports of overlaping stack and small stack
7770 size. If the space for the stack is less than 16 bytes aslink trows a
7773 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7774 the 8051. Option 'y' for memory summary output file.
7776 Changes to sdcc (All the changes are marked with 'JCF'):
7778 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7780 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7781 overlaying area for it (uses RegBankUsed[4]).
7783 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7784 bank zero as used by default. By default aslink locates the stack
7785 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7786 the creation of the .mem file. Delegates the allocation of data area
7787 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7788 the begining of the stack area to aslink.
7790 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7791 glue() in SDCCglue.c creates an area for it.
7793 2002-09-03 Borut Razem <borut.razem AT siol.net>
7794 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7795 sdcc/src/pic/glue.c:
7796 introduced atexit() handler for teporay files removal in case of
7797 errors, assertions, ...
7799 2002-08-29 Borut Razem <borut.razem AT siol.net>
7800 * sdcc/support/cpp2/auto-host_vc_in.h:
7801 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7802 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7803 Maybe there is a similar problem with BORLANDC? It should be checked!
7805 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7806 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7807 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7808 was not executed, and the compiler (cl) launched a warning:
7809 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7811 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7812 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

7824 - added Release configuration in VS projects
7825 - review of compiler an linker options
7826 - VC .exe files are generated in bin_vc directory, not to interfere
7827 with binaries generated from other projects (cygwin, mingw, bcc ...)
7829 * sdcc/src/yacc.dsp: added
7831 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7832 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7833 and insert the version number definitions from .version
7835 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7837 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7844 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7846 2002-08-11 Borut Razem <borut.razem AT siol.net>
7847 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7849 2002-08-10 Borut Razem <borut.razem AT siol.net>
7850 * src/SDCCmain.c (main):
7851 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7852 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7853 The consequence was that some temporary files were not removed.
7856 unification of code in functions tempfilename() and tempfile():
7857 function tempnam() is defined in Visual Studio 6.0 and .NET
7859 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7861 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7862 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7863 - removed compiler command line option /WX: Treats all warnings as errors
7864 - update a list of source files, included into the project
7866 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7867 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7868 changed project type to Generic Project so that can be correcly converted to VS.NET project
7870 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7872 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7876 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7877 added return 0 statements after assert() to make compiler happy
7879 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7880 added newline in the def file to keep MSC compiler satisfied
7882 * sdcc/src/z80/gen.c:
7883 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7884 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7885 - solved MSC error in function aopDump()
7887 * sdcc_vc.h: define PREFIX as "\\sdcc"
7889 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7944 Compiler generated registers for interrupt context saving
7945 were not getting allocated.
7947 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7950 Fixed left shift. Will promote the left side of a left shift
7951 if a) left shifting more than size of operand or b) when assigned
7952 to something size > size of left side
7954 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8064 * sdcc/src/SDCCloop.c:
8065 Previous fix was not good. basic blocks that have "break" or "return" are
8066 not really partof a loop , but live ranges used in these blocks should
8067 be live thru the entire loop, so set partOfLoop but don't add them to
8070 2002-02-21 <johan AT FRIJA>

8914 2001-09-02 Michael Hope <michaelh AT juju.net.nz>
8916 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
8918 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
8920 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
8922 * 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.
8924 2001-09-01 Michael Hope <michaelh AT juju.net.nz>
8926 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
8927 (genCmp): Fixed up genCmp for the GB with longs.
8929 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
8931 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
8933 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
8935 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

8939 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
8941 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
8943 * 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.
8945 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
8947 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
8949 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
8951 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
