576 on rIfx (genCmp was broken)
578 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
580 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
581 * src/z80/main.c (_keywords[]),
582 * src/SDCCglobal.h (struct options),

587 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
588 always available in leading double underscore form. The C99 support is
589 mostly missing, but it's a start.
590 * support/regression/tests/bug-227710.c: fixed nonconforming use of
591 reserved identifier "__data".
593 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

639 2005-03-20 Borut Razem <borut.razem AT siol.net>
641 * support/scripts/inc2h.pl: WIN32 port

661 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
664 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

667 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
669 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
671 * device/lib/printf_large.c: removed inline assembly for portability and
672 readability. Use printf_fast if speed or size are more important.
673 * src/pic16/gen.c: removed conditions around use of DEBUGpc
674 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
676 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
678 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
679 prevent compiler warning
681 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
683 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
684 moved to level 0 and declared as static. Also they are explicit
685 placed in access bank. This was necessery because some times they
686 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
687 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
688 optimizations. Currently only compare to unsigned char is implemented,
689 * src/pic16/gen.c: added fReturnIdx array,
690 * (struct resolvedIfx) is moved to gen.h and made public,
691 * (struct _G): added sregsAlloc and sregsAllocSet fields,
692 * (aopForSym): added an optimization to directly store in stack of
693 the operand of a SEND iCode,
694 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
695 but as registers instead (AOP_REG) using the fReturnIdx array,
696 * (pic16_freeAsmop): remove the freed register from the
698 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
700 * (pic16_popGetTempRegCond): changed function prototype, now
701 function takes also a bitVector argument v which holds the current
702 set of registers that are allocated for stack access by aopForSym,
703 registers allocated in aopForSym for accessing stack symbols are not
704 any more part of the functions usedRegs field,
705 * (genCall): some times aopOp is called for a stack variable to be
706 send, aopForSym might perform the push, if this is true make sure
707 that genCall doesn't push the variable twice by testing _G.resDirect,
708 * (genFunction): changed testing for unspecified interrupt number
709 from 256 to INTNO_UNSPEC,
710 * modified selection scheme of frame pointer generation. Previously
711 if function did use local registers a frame pointer was generated,
712 now a frame pointer is generated only if function has arguments
713 (that need PLUSW2 register access), or has stack arguments, or the
714 compiler is not instructed to omit the frame pointer,
715 * (genEndFunction): before restoring local registers that were saved
716 in the function preamble, also restore the registers that *might*
717 have been allocated for stack access,
718 * (genRet): removed some old comments,
719 * (genCmp, the active (RN's) version): added a call to the
720 pic16_genCmp_special function to perform the compare with a more
721 robust and optimized way,
722 * (genInline): a feature has been added in inline code generation,
723 which allows a wildcard variable substitution when writing inline
724 assembly. Code is incomplete and experimental therefore undocumented,
725 * (genCast): changed order of aopOp for result and right to allow
726 aopForSym to directly load the result if possible,
727 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
728 perform an optimized compare on some selected special occasions,
729 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
730 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
731 generate an IVT any more,
732 * src/pic16/main.c (pic16_optionsTable): added command line option
734 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
735 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
737 * src/pic16/NOTES: Raphael Neider added in list of active developers
738 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
739 jumptable_end to prevent bug #,
740 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
741 inCond and outCond fields,
742 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
743 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
744 turn off register spilling,
745 * (packRegsForOneUse): synced with other ports' versions although it
746 is not used currently,
747 * (pic16_packRegisters): added an optimization while reading
748 structure bitfields, some registers may be saved (malloc code is
749 decreased by 80 bytes)
751 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
753 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
754 left is a bitfield, if yes, then don't optimize assignment. Perhaps
755 this can be optimized more?
757 2005-03-10 Raphael Neider <rneider AT web.de>
759 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
760 genNearPointerGet): (hopefully) fixed access to bitfields via
761 pointers (p->bitN = x; and x = p->bitN; failed)
763 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
765 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1395 Adding support for replacing ljmps with sjmps in jumptables
1396 generated for switch statements. For now you need to set the
1397 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1398 Now 4 algorithms for mcs51 jumptable generation are used:
1399 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1400 addresses loaded pc-relative for up to 112 cases and stack-pushing
1401 target addresses loaded with offset from dptr for up to 256 cases.

1428 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1429 to call when a stack overflow occurs,
1430 * (malloc.h): added CVS Id tag,
1431 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1433 * added libc directory. The current version of LibC contains string
1434 functions, ctype functions and macros and some functions of the
1435 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1436 be extensively tested in the future. Standard disclaimer here.
1437 Library is not automatically build yet. But one can build it by
1438 invoking 'make' inside the libc directory.
1439 * added ADC library under libio. Preliminary version yet.
1441 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1448 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1449 * (pic16_storeForReturn): optimized return of 0,
1450 * (genCmp): experimental code for new genCmp which uses PIC18's
1451 special compare&skip instructions. Initial tests fail some times
1452 with variables grater than 1 byte in size, so new code is disabled,
1453 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1455 * (genCast): began a fix to optimize the casting of a bit to another
1456 bit, now assigning a bitfield to another bitfield will fail, sorry,
1457 * src/pic16/main.c: disabled the use of lr-support feature,
1458 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1459 * added some function prototypes, added function _debugf prototype,

1461 bits with offset (case PO_GPR_BIT),
1462 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1464 * (isBankInstruction): modified to return 0 for no banking instruction,
1465 and 1 for banking instruction,
1466 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1467 caused stop processing pCodes after a inline assembly block,
1468 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1469 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1470 registers when it shouldn't,
1471 * src/pic16/ralloc.c (allocReg): add preliminary support for
1472 supporting a limited set of temporary registers,
1474 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1476 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1477 genDataPointerSet): ensure assignments always copy in MSB to LSB
1479 (loadRegFromAop): recognize CLRH optimization,
1480 (genFunction): optimize RECEIVE iCodes in reentrant functions
1482 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1484 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4479 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4481 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4482 loaded with the linker search paths (-L arguments) and the libraries
4483 to be linked with the current source (-l arguments). Changes
4484 currently will affect only the pic16 port.
4485 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4486 include path the port specific paths and port specific libraries,
4487 * gplink command now contains the $3 argument,
4488 * src/pic16/device.h,
4489 * src/pic16/device.c,: structure PIC_device is made public and
4490 renamed to PIC16_device, the same for variable Pics which is renamed
4491 to Pics16. Updated all references to them.
4492 * src/pic16/glue.c (pic16glue): corrected bug with code
4493 initialization which bypassed the variable initializations block.

4503 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4505 Documenting changes from previous commits.
4506 * configure.in (version 1.56),
4507 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4508 when generating output files to configure the pic16 library,
4509 but now I've commented it out, since gputils aren't installed in the
4510 SF compile farm, so library won't compile
4512 * device/lib/Makefile.in (version 1.56): initially I've added in
4513 target 'all' the prerequestive 'model-pic16' so it compiled the
4514 pic16 library, but now I've commented it out for the same reasons
4516 * added targets 'model-pic16' and 'objects-pic16' to compile the
4518 * added target 'port-specific-objects-pic16' to handle the
4519 generated libraries and copy them into the build/ directory
4520 * added target 'clean-intermediate-pic16' to clean intermediate
4521 files into pic16 directory
4522 * in target 'installdirs' added line to create directory pic16 in
4523 the installation path
4525 * device/include/Makefile.in (version 1.11): in target 'install'
4526 added lines to copy all header files to installation path,
4527 * in target 'installdirs' added line create directory for pic16
4528 headers in the installation path

4543 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4544 option so that it actually works. Made it specific to the z80, since
4545 the gbz80 doesn't have these kinds of I/O ports.
4547 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4549 * device/include/z180.h,

4562 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4564 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4565 changed interrupt vector table generation to only emit declared vectors.
4566 * device/include/Makefile.in: added missing backslash
4567 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4569 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4571 Mainly changes to support compilation of the device libraries
4572 * src/pic16/device.c: stack is allocated via symbol and not
4573 via literal number. The symbol is placed in the corresponding
4574 position of the data ram
4575 * (pic16_dump_section): relocatable and absolute uninitialized
4576 data are now emitted in sorted order to reduce section naming,
4577 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4578 weren't marked as being in the access bank,
4580 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4582 Added portion of GNU PIC Library under the directory
4583 device/include/pic16 and device/lib/pic16. These files
4584 contain the declarations of SFRs for the PIC18Fxx2 devices.
4585 The directory is initialized via configure from toplevel.
4587 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4589 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4590 the spilllocations to be compared correctly
4592 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4594 * src/SDCCast.c (decorateType): fixed bug introduced today
4596 2004-01-12 Borut Razem <borut.razem AT siol.net>
4598 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4601 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4603 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4604 in simpler and even better code
4606 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4608 * src/SDCCicode.c (operandOperation): fixed bug #874819

4612 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4614 * doc/sdccman.lyx: Moved and added some sections, small changes
4615 all over. Telling LaTeX to be less strict with word spacing
4616 to better keep the right margin. Changed some notes about
4617 maintainance of the ports in section 3.2.1 - is it OK like this?
4619 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4621 SDCC source changes:
4622 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4655 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4656 UPPER for immediate operands,
4657 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4659 * src/pic16/peeph.def: all peepholes with movff are commented out,
4660 because there is a problem in the pcode peep optimizer,
4661 * src/pic16/ralloc.c: the register allocator can now reuse local
4662 function symbols for another function. This saves register usage.
4663 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4665 Added file src/pic16/NOTES with information about program writing on
4666 the current port version.

4675 * src/SDCCmain.c : fixed #872250: -l command line defined library
4676 files are scanned before standard library files
4678 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4695 gen51Code): more efficient parameter receive for --model-large
4698 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4701 * src/z80/main.c: added missed needLinkerScript flags (more than
4702 one port structure defined in these file)
4703 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4719 needLinkerScript flag
4721 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4722 * src/pic/glue.c: added variable udata_section_name to
4723 override default uninitialized data segment definition for
4724 devices only with SHAREBANK memory (reported from Erik Epetrich)
4725 * (pic14emitOverlay): modified to emit a commented overlay segment
4726 directive when no overlay data exist
4727 * (picglue): modified to emit uninitialized data segment
4728 according to udata_section_name

4733 arguments via -W option
4734 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4735 object file from '.rel' to '.o' in port->linker structure,
4736 changed size of fptr from 2 to 3 in port structure
4738 2004-01-07 Borut Razem <borut.razem AT siol.net>
4740 * support/scripts/sdcc.nsi: update PATH
4741 * support/scripts/sdcc.ico: craeted
4743 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

4746 * doc/Makefile: fix install
4748 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4750 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4752 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4753 how the function variable allocation summary is displayed; also
4754 include information about variables allocated to the overlay
4757 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4759 * as/mcs51/lkmain.c: Help about -Y option

4769 LEFT_OP (left shift)
4771 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4773 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4774 (default behaviour).
4776 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4778 A python script to validate compiler diagnostic messages. It can be
4779 used to verify that sdcc complains about bad c source code and
4780 gives a good location of the error.
4781 * support/valdiag/Makefile,
4782 * support/valdiag/valdiag.py,
4783 * support/valdiag/tests/*
4785 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4798 * src/common.h: added ifndef/define/endif macros
4799 around the header file.
4800 Bug reported from Jesus Calvino-Fraga
4802 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4804 * sdcc.spec: updated
4805 * device/include/Makefile.in: don't install CVS directories
4806 * device/lib/Makefile.in: added removal of CVS directories after install
4807 * doc/Makefile: fixed install, added local_icons
4808 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4809 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4810 * src/ds390/gen.c (genRightShift): fixed bug #870788
4811 * src/SDCCast.c (decorateType): fixed bug #870781
4813 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4815 PIC16 port related changes:
4816 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4817 added variable stackPos,
4819 * gen.c: genCall, assignResultValue: added support for
4820 pushing/retrieving function parameters to/from stack,
4821 genFunction,genEndFunction: setup stack frame for the
4823 genAddrOf: will be changed according to bug 863624
4825 * added files genutils.c and genutils.h which contain gen*
4826 debugged and optimised functions extracted from gen.c
4828 * glue.c: added variable 'externs' which holds extern symbols,
4829 pic16emitRegularMap: is modified to properly handle relocatable
4830 symbols under the new scheme,
4831 pic16createInterruptVect: is modified
4832 pic16printPublics: is modified to emit 'global' assembler directives,
4833 added pic16_printExterns to print extern symbols,
4834 pic16glue: initializes stack/frame pointer in the beginning of
4835 the assembly output. Temporary hack, will be corrected later,
4836 because gplink yet does not support stack and SDCC does not
4837 yet support a type of crt0.o object to create the final binary.
4839 * Removed many lines that contain 8051 legacy code.
4840 * The code is finally placed under a 'code' directive.
4841 * Added port specific options.
4843 * _process_pragma: simplified since now we do not need *special*
4844 include file to define SFR registers. But a separate header
4845 will be needed. This will be developed later.
4846 * _pic16_parseOptions: added, parses port specific options:
4847 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4848 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4849 --preplace-udata-with=
4851 * _pic16_setDefaultOptions: modified to initialize section names,
4852 but hack is temporarly out of order since it needs improvement.
4853 * _pic16_genAssemblerPreamble: configuration words are emitted by
4854 their address instead of their name. This part is incomplete and
4855 supports only the 18Fxx2 devices. Other devices will emit an error
4856 during assembly since they do not contain the same set of config
4858 * _pic16_genIVT: is modified,
4860 * pcode.c: added definitions for some hardware registers that are needed
4862 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4863 All PCI entries are updated. Now LFSR is supported.
4864 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4865 * added pic16_newpCodeOpLit2 to support instructions with
4866 two literal arguments
4867 * pic16_pCode2str: corrected code that emits assembler instructions
4868 with two literal operands and those that have an access bit modifier
4869 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4870 this fixes a bug which caused some labels to be lost, when an
4871 assembler directive was added, i.e. banksel,
4872 * pic16_FixRegisterBanking: improved logic that causes the insertion
4874 * InlineFunction: functions that are called once, are not any more
4875 inlined. This can be a port option in the future,
4877 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4879 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4880 hold the corresponding uninitialized symbols,
4881 * pic16_allocProcessorRegister: registers have explicit marked the
4883 * pic16_allocInternalRegister: registers are explicit marked as
4885 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4886 processing list, so bit registers were lost,
4889 * ralloc.h: added field 'accessBank' and original symbol operand
4890 in register definition,
4891 * removed the field isMapped from register definition,
4893 ** Several functions have been removed from various sources:
4894 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4895 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4896 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4897 pic16_assignRelocatableRegisters
4899 ** others have been introduced:
4900 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4901 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4903 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4905 * support/scripts/inc2h.pl: changed definition of BIT_AT
4906 to emit 'sbit at' instead of 'bit at'. This was a request.
4908 PIC16 port related preliminary changes:
4909 * gen.c: prefixed function popRegFromString with
4910 pic16_ and all references to it corrected
4911 * pcode.c: all pic16_pc_* hardware registers prefixed
4912 with underscore (_),
4913 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4914 * ralloc.c: newReg(): when register is REG_SFR then
4915 set address to rIdx,
4916 pic16_allocProcessorRegister(): marks register wasUsed=0
4917 pic16_writeUsedRegs(): added a call to assign processor
4918 registers via pic16_assignFixedRegisters
4920 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4922 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4923 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4924 variables in unused register banks. Also the SSEG is placed
4925 wherever there is enough space for it, and IDATA can be anywhere
4926 in internal RAM. For now compile using -Wl-Y[stack_size].
4927 The mem file is different for this option as well, since it

5926 iCode properly now. Use getSize instead of nRegs since a & b
5927 aren't part of the nRegs tally.
5929 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5931 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
5932 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5933 before instructions that use the _STATUS register
5935 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5937 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5938 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5939 fetching of the pointer
5940 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5941 copied from genNearPointerSet()
5942 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5943 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5944 If they pop r0/r1 they must be called in the opposite order than aopOp().
5945 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5946 (resp. --stack-auto), prepared for --xstack

5957 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5959 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5960 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5961 type for bits was changed. It resulted in bit variables becoming
5962 global, which is not permitted in PIC 14 assembly output.
5964 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5966 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5979 A few small changes that speed up the peephole optimizer.
5983 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5985 Try to make the peephole optimizer smarter by maintaining
5986 an association between the assembly source code and the
5987 iCodes that originated them. Put this information to use
5988 with a new peephole rule condition "notVolatile" so that
5989 the rules can be aggressive yet still safe.
5994 * src/mcs51/peeph.def
5996 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6000 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6001 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6002 if the left or right operand symbols have the accuse flag set.
6004 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6006 Changed the type of the result of the ! (NOT) operator to char;
6007 previously it returned the same type as the source. This allows
6008 us to eliminate all the genFloatNot functions (all of its target
6009 implementations were very buggy) since !float can use the same
6012 * src/SDCCicode.c (ast2iCode): ! returns char

6014 * src/ds390/gen.c (genNot, genNotFloat),
6015 * src/z80/gen.c (genNot, genNotFloat),
6016 * src/pic/gen.c (genNot, genNotFloat),

6021 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6022 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6023 during interrupts. Ensure WSAVE is located at a shared bank address.
6024 2. Fixed page selection in some places
6025 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6026 the registers name strings.
6027 4. Fixed "signed / unsigned compare" compiler warnings.
6028 5. The PIC port manages its own allocation of the general purpose
6029 registers, but makes no attempt to reuse them. As a result when
6030 compiling it soon runs out of general purpose registers. Some
6031 additional code was added to the files pcode.c and device.c to walk
6032 through the function call tree and rename the registers so that they
6042 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6043 genPlus() & genMinus() when the result is the same as left or right

6049 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6051 Made bitfield a distinct type from bit so that bitfields
6052 convert as per ANSI C and bits retain their traditional
6053 boolean style behaviour. Implemented bitfield support in
6061 * src/ds390/gen.c: bit v bitfield split
6062 * src/z80/gen.c: New support for bitfields
6063 * support/regression/tests/bitfields.c: reenabled z80,
6066 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6068 Rules 246.x, 247.x relate to bitfields, the others speed up
6069 access to xdata mapped I/O devices.
6071 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6073 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6075 Cleaned up genPackBits and genUnpackBits and added two helper
6076 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6077 for literal assignments in genPackBits (thanks to Frieder for
6083 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6085 Fixed bug #748310 (pointer to function type mishandled when the
6086 function name is omitted). Also fixed a SIGSEGV when a function
6087 attribute (reentrant, etc) is used on a non-function or on a
6088 function but misplaced before the parameter list.
6090 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6092 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6115 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6117 Made the constant following the "interrupt" keyword optional. If
6118 omitted, the function will not automatically be given an entry
6119 in the interrupt vector table (similar to #pragma NOIV, but
6120 less syntacticly kludgy). The interrupt number is also now
6121 range checked. Also fixed a bug in the high order bit example

6135 * src/SDCCicode.c (operandOperation): rewritten some ops
6136 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6137 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6139 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6140 be re-activated by defining REDUCE_LITERALS)
6141 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6142 unsigned, but are signed by default
6143 * src/SDCCval.c (constVal): rearranged
6144 * src/SDCCval.c (valMod): preliminary fix
6145 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6597 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6598 the regression tests I'm not brave enough to enable 245.b, 245.c
6599 * doc/sdccman.lyx: added latex preamble for hyperref package.
6600 Using pdflatex this will give you a hyperlinked pdf file with
6601 bookmarks. (prepend '%' before /usepackage if this breaks something)

6617 Applied patch from bug 737905 (renamed yylineo to mylineno):
6624 * src/pic16/pcode.c: Cleaned warnings
6625 * src/pic16/pcodeflow.c: Cleaned warnings
6626 * src/pic16/pcoderegs.c: Cleaned warnings

6639 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6641 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6642 it can be defined with CFLAGS when running configure
6643 * src/SDCCmain.c: fixed compiling + linking with object files
6645 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6648 added --disable-pic16-port
6649 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6650 * src/SDCCmain.c: linkOptions is changed to set *,
6651 added if/endif conditional macros to remove options help
6652 messages from optionsTable when a port is not configured, added
6653 support for the PIc16 port in the ports table, when executing
6654 the compiler with no port specified on command line, a default
6655 port is selected with the new macro DEFAULT_PORT which is
6656 defined in port.h, in setDefaultOptions() linkOptions is removed
6657 from initialization assignment, since now it is a set,
6658 parseCmdLine uses setParseWithComma for linkOptions, in
6659 linkEdit() linkOptions are accessed with new function indexSet()
6660 which returns the i'th item of a set variable. See SDCCset.c, in
6661 linkEdit() when calling buildCmdLine(), added linkOptions as
6662 last argument. Now users can pass arguments to gplink via the
6663 -Wl option, main() uses pic16glue() to glue up pic16 programs
6664 * src/SDCCpeeph.c: various changes to support pic16

6675 * src/pic16/glue.c: commented out some error producing lines
6676 * src/pic16/main.c: __config directives are commented out to stop
6677 gpasm complaining and test the linkage with gplink, _linkCmd and
6678 _asmCmd changed to be more gplink and gpasm friendly
6679 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6680 produced an error when parsed, peep rule 12 is added to utilize
6681 movff, but it is commented out since the pCode does not support
6682 yet a command with 2 address arguments
6684 2003-05-18 <johan AT balder>
6686 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6687 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6711 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6713 2003-05-11 Borut Razem <borut.razem AT siol.net>
6715 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6716 the path of bin directory, so that PATH is the only env. variable, which has to be set
6717 in case of standard installation.
6718 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7747 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7749 * in \sdcc\as\mcs51\ changed these files in order to create an
7750 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7751 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7752 following files to include the previous two files: aslink.dsp,
7753 Makefile.aslink, Makefile.bcc, and Makefile.in.
7755 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7756 .adb instead of .cdb
7758 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7760 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7761 value from option --iram-size.
7763 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7765 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7768 2002-09-18 <wiml AT hhhh.org>
7770 * SDCClrange.h: exposed setFromRange() and setToRange()
7771 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7772 packRegsForAccUse() (bug 542397)
7773 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7774 multiple times and emitting the fetch operations more than once
7775 added aopGetUsesAcc() function to allow binary operators to
7776 fetch their operands in the correct order; made genMinus() emit
7777 compact code for X = LITERAL - Y
7779 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7780 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7781 sprintf() in line 1267.
7783 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7784 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7787 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7788 Changes to aslink (All the changes are marked with 'JCF'):
7790 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7793 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7794 area BSEG. Also moves, if possible, the DATA area down into the internal
7795 ram so more space is available.
7797 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7800 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7801 not bytes. Function summary() which creates a memory usage summary
7802 file with extension .mem. Reports of overlaping stack and small stack
7803 size. If the space for the stack is less than 16 bytes aslink trows a
7806 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7807 the 8051. Option 'y' for memory summary output file.
7809 Changes to sdcc (All the changes are marked with 'JCF'):
7811 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7813 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7814 overlaying area for it (uses RegBankUsed[4]).
7816 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7817 bank zero as used by default. By default aslink locates the stack
7818 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7819 the creation of the .mem file. Delegates the allocation of data area
7820 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7821 the begining of the stack area to aslink.
7823 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7824 glue() in SDCCglue.c creates an area for it.
7826 2002-09-03 Borut Razem <borut.razem AT siol.net>
7827 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7828 sdcc/src/pic/glue.c:
7829 introduced atexit() handler for teporay files removal in case of
7830 errors, assertions, ...
7832 2002-08-29 Borut Razem <borut.razem AT siol.net>
7833 * sdcc/support/cpp2/auto-host_vc_in.h:
7834 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7835 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7836 Maybe there is a similar problem with BORLANDC? It should be checked!
7838 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7839 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7840 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7841 was not executed, and the compiler (cl) launched a warning:
7842 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7844 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

7850 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7851 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7852 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7853 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7854 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7855 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7856 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7857 - added Release configuration in VS projects
7858 - review of compiler an linker options
7859 - VC .exe files are generated in bin_vc directory, not to interfere
7860 with binaries generated from other projects (cygwin, mingw, bcc ...)
7862 * sdcc/src/yacc.dsp: added
7864 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7865 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7866 and insert the version number definitions from .version
7868 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7870 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7879 2002-08-11 Borut Razem <borut.razem AT siol.net>
7880 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7882 2002-08-10 Borut Razem <borut.razem AT siol.net>
7883 * src/SDCCmain.c (main):
7884 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7885 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7886 The consequence was that some temporary files were not removed.
7889 unification of code in functions tempfilename() and tempfile():
7890 function tempnam() is defined in Visual Studio 6.0 and .NET
7892 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7894 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7895 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7896 - removed compiler command line option /WX: Treats all warnings as errors
7897 - update a list of source files, included into the project
7899 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7900 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7901 changed project type to Generic Project so that can be correcly converted to VS.NET project
7903 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7905 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7909 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7910 added return 0 statements after assert() to make compiler happy
7912 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7913 added newline in the def file to keep MSC compiler satisfied
7915 * sdcc/src/z80/gen.c:
7916 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7917 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7918 - solved MSC error in function aopDump()
7920 * sdcc_vc.h: define PREFIX as "\\sdcc"
7922 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7974 Initialized the new field char *Processor field to NULL in all ports
7977 Compiler generated registers for interrupt context saving
7978 were not getting allocated.
7980 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7983 Fixed left shift. Will promote the left side of a left shift
7984 if a) left shifting more than size of operand or b) when assigned
7985 to something size > size of left side
7987 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7989 tons of changes. Register allocation has been
7990 rewritten. Added customization for the various PICs. Flow

8095 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8097 * sdcc/src/SDCCloop.c:
8098 Previous fix was not good. basic blocks that have "break" or "return" are
8099 not really partof a loop , but live ranges used in these blocks should
8100 be live thru the entire loop, so set partOfLoop but don't add them to
8103 2002-02-21 <johan AT FRIJA>
