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

660 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
662 * device/lib/printf_large.c: removed inline assembly for portability and
663 readability. Use printf_fast if speed or size are more important.
664 * src/pic16/gen.c: removed conditions around use of DEBUGpc
665 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
667 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
669 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
670 prevent compiler warning
672 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
674 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
675 moved to level 0 and declared as static. Also they are explicit
676 placed in access bank. This was necessery because some times they
677 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
678 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
679 optimizations. Currently only compare to unsigned char is implemented,
680 * src/pic16/gen.c: added fReturnIdx array,
681 * (struct resolvedIfx) is moved to gen.h and made public,
682 * (struct _G): added sregsAlloc and sregsAllocSet fields,
683 * (aopForSym): added an optimization to directly store in stack of
684 the operand of a SEND iCode,
685 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
686 but as registers instead (AOP_REG) using the fReturnIdx array,
687 * (pic16_freeAsmop): remove the freed register from the
689 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
691 * (pic16_popGetTempRegCond): changed function prototype, now
692 function takes also a bitVector argument v which holds the current
693 set of registers that are allocated for stack access by aopForSym,
694 registers allocated in aopForSym for accessing stack symbols are not
695 any more part of the functions usedRegs field,
696 * (genCall): some times aopOp is called for a stack variable to be
697 send, aopForSym might perform the push, if this is true make sure
698 that genCall doesn't push the variable twice by testing _G.resDirect,
699 * (genFunction): changed testing for unspecified interrupt number
700 from 256 to INTNO_UNSPEC,
701 * modified selection scheme of frame pointer generation. Previously
702 if function did use local registers a frame pointer was generated,
703 now a frame pointer is generated only if function has arguments
704 (that need PLUSW2 register access), or has stack arguments, or the
705 compiler is not instructed to omit the frame pointer,
706 * (genEndFunction): before restoring local registers that were saved
707 in the function preamble, also restore the registers that *might*
708 have been allocated for stack access,
709 * (genRet): removed some old comments,
710 * (genCmp, the active (RN's) version): added a call to the
711 pic16_genCmp_special function to perform the compare with a more
712 robust and optimized way,
713 * (genInline): a feature has been added in inline code generation,
714 which allows a wildcard variable substitution when writing inline
715 assembly. Code is incomplete and experimental therefore undocumented,
716 * (genCast): changed order of aopOp for result and right to allow
717 aopForSym to directly load the result if possible,
718 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
719 perform an optimized compare on some selected special occasions,
720 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
721 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
722 generate an IVT any more,
723 * src/pic16/main.c (pic16_optionsTable): added command line option
725 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
726 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
728 * src/pic16/NOTES: Raphael Neider added in list of active developers
729 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
730 jumptable_end to prevent bug #,
731 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
732 inCond and outCond fields,
733 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
734 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
735 turn off register spilling,
736 * (packRegsForOneUse): synced with other ports' versions although it
737 is not used currently,
738 * (pic16_packRegisters): added an optimization while reading
739 structure bitfields, some registers may be saved (malloc code is
740 decreased by 80 bytes)
742 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
744 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
745 left is a bitfield, if yes, then don't optimize assignment. Perhaps
746 this can be optimized more?
748 2005-03-10 Raphael Neider <rneider AT web.de>
750 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
751 genNearPointerGet): (hopefully) fixed access to bitfields via
752 pointers (p->bitN = x; and x = p->bitN; failed)
754 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
756 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

798 to keep the correct label reference count when adding/removing references
799 to labels. A peephole file using this is appended to patch #1144962.

1384 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1386 Adding support for replacing ljmps with sjmps in jumptables
1387 generated for switch statements. For now you need to set the
1388 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1389 Now 4 algorithms for mcs51 jumptable generation are used:
1390 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1391 addresses loaded pc-relative for up to 112 cases and stack-pushing
1392 target addresses loaded with offset from dptr for up to 256 cases.

1419 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1420 to call when a stack overflow occurs,
1421 * (malloc.h): added CVS Id tag,
1422 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1424 * added libc directory. The current version of LibC contains string
1425 functions, ctype functions and macros and some functions of the
1426 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1427 be extensively tested in the future. Standard disclaimer here.
1428 Library is not automatically build yet. But one can build it by
1429 invoking 'make' inside the libc directory.
1430 * added ADC library under libio. Preliminary version yet.
1432 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1439 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1440 * (pic16_storeForReturn): optimized return of 0,
1441 * (genCmp): experimental code for new genCmp which uses PIC18's
1442 special compare&skip instructions. Initial tests fail some times
1443 with variables grater than 1 byte in size, so new code is disabled,
1444 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1446 * (genCast): began a fix to optimize the casting of a bit to another
1447 bit, now assigning a bitfield to another bitfield will fail, sorry,
1448 * src/pic16/main.c: disabled the use of lr-support feature,
1449 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1452 bits with offset (case PO_GPR_BIT),
1453 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1455 * (isBankInstruction): modified to return 0 for no banking instruction,
1456 and 1 for banking instruction,
1457 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1458 caused stop processing pCodes after a inline assembly block,
1459 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1460 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1461 registers when it shouldn't,
1462 * src/pic16/ralloc.c (allocReg): add preliminary support for
1463 supporting a limited set of temporary registers,
1465 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1467 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1468 genDataPointerSet): ensure assignments always copy in MSB to LSB
1470 (loadRegFromAop): recognize CLRH optimization,
1471 (genFunction): optimize RECEIVE iCodes in reentrant functions
1473 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1475 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1476 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1478 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1487 instead of sjmp to ret
1488 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1489 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1491 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4470 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4472 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4473 loaded with the linker search paths (-L arguments) and the libraries
4474 to be linked with the current source (-l arguments). Changes
4475 currently will affect only the pic16 port.
4476 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4477 include path the port specific paths and port specific libraries,
4478 * gplink command now contains the $3 argument,
4479 * src/pic16/device.h,
4480 * src/pic16/device.c,: structure PIC_device is made public and
4481 renamed to PIC16_device, the same for variable Pics which is renamed
4482 to Pics16. Updated all references to them.
4483 * src/pic16/glue.c (pic16glue): corrected bug with code
4484 initialization which bypassed the variable initializations block.

4494 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4496 Documenting changes from previous commits.
4497 * configure.in (version 1.56),
4498 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4499 when generating output files to configure the pic16 library,
4500 but now I've commented it out, since gputils aren't installed in the
4501 SF compile farm, so library won't compile
4503 * device/lib/Makefile.in (version 1.56): initially I've added in
4504 target 'all' the prerequestive 'model-pic16' so it compiled the
4505 pic16 library, but now I've commented it out for the same reasons
4507 * added targets 'model-pic16' and 'objects-pic16' to compile the
4509 * added target 'port-specific-objects-pic16' to handle the
4510 generated libraries and copy them into the build/ directory
4511 * added target 'clean-intermediate-pic16' to clean intermediate
4512 files into pic16 directory
4513 * in target 'installdirs' added line to create directory pic16 in
4514 the installation path
4516 * device/include/Makefile.in (version 1.11): in target 'install'
4517 added lines to copy all header files to installation path,
4518 * in target 'installdirs' added line create directory for pic16
4519 headers in the installation path
4521 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4534 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4535 option so that it actually works. Made it specific to the z80, since
4536 the gbz80 doesn't have these kinds of I/O ports.
4538 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4540 * device/include/z180.h,

4553 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4555 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4556 changed interrupt vector table generation to only emit declared vectors.
4557 * device/include/Makefile.in: added missing backslash
4558 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4560 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4562 Mainly changes to support compilation of the device libraries
4563 * src/pic16/device.c: stack is allocated via symbol and not
4564 via literal number. The symbol is placed in the corresponding
4565 position of the data ram
4566 * (pic16_dump_section): relocatable and absolute uninitialized
4567 data are now emitted in sorted order to reduce section naming,
4568 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4569 weren't marked as being in the access bank,
4571 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4573 Added portion of GNU PIC Library under the directory
4574 device/include/pic16 and device/lib/pic16. These files
4575 contain the declarations of SFRs for the PIC18Fxx2 devices.
4576 The directory is initialized via configure from toplevel.
4578 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4580 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4581 the spilllocations to be compared correctly
4583 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4585 * src/SDCCast.c (decorateType): fixed bug introduced today
4587 2004-01-12 Borut Razem <borut.razem AT siol.net>
4589 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4592 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4594 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4595 in simpler and even better code
4597 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4599 * src/SDCCicode.c (operandOperation): fixed bug #874819

4605 * doc/sdccman.lyx: Moved and added some sections, small changes
4606 all over. Telling LaTeX to be less strict with word spacing
4607 to better keep the right margin. Changed some notes about
4608 maintainance of the ports in section 3.2.1 - is it OK like this?
4610 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4612 SDCC source changes:
4613 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4646 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4647 UPPER for immediate operands,
4648 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4650 * src/pic16/peeph.def: all peepholes with movff are commented out,
4651 because there is a problem in the pcode peep optimizer,
4652 * src/pic16/ralloc.c: the register allocator can now reuse local
4653 function symbols for another function. This saves register usage.
4654 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4656 Added file src/pic16/NOTES with information about program writing on
4657 the current port version.

4666 * src/SDCCmain.c : fixed #872250: -l command line defined library
4667 files are scanned before standard library files
4669 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4683 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4685 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
4686 gen51Code): more efficient parameter receive for --model-large
4689 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4692 * src/z80/main.c: added missed needLinkerScript flags (more than
4693 one port structure defined in these file)
4694 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
4697 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

4700 * src/port.h: added flag needLinkerScript in port->linker
4701 structure to inform whether to create a .lnk file or not,
4709 * src/z80/main.c: changed appropriately to configure
4710 needLinkerScript flag
4712 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4713 * src/pic/glue.c: added variable udata_section_name to
4714 override default uninitialized data segment definition for
4715 devices only with SHAREBANK memory (reported from Erik Epetrich)
4716 * (pic14emitOverlay): modified to emit a commented overlay segment
4717 directive when no overlay data exist
4718 * (picglue): modified to emit uninitialized data segment
4719 according to udata_section_name

4724 arguments via -W option
4725 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4726 object file from '.rel' to '.o' in port->linker structure,
4727 changed size of fptr from 2 to 3 in port structure
4729 2004-01-07 Borut Razem <borut.razem AT siol.net>
4731 * support/scripts/sdcc.nsi: update PATH
4732 * support/scripts/sdcc.ico: craeted
4734 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4736 * device/include/Makefile.in: fix install
4737 * doc/Makefile: fix install
4739 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4741 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4743 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4744 how the function variable allocation summary is displayed; also
4745 include information about variables allocated to the overlay
4748 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4750 * as/mcs51/lkmain.c: Help about -Y option

4760 LEFT_OP (left shift)
4762 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4764 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4765 (default behaviour).
4767 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4769 A python script to validate compiler diagnostic messages. It can be
4770 used to verify that sdcc complains about bad c source code and
4771 gives a good location of the error.
4772 * support/valdiag/Makefile,
4773 * support/valdiag/valdiag.py,
4774 * support/valdiag/tests/*
4776 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4778 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4779 * src/SDCCsymt.c (newEnumType),
4781 * support/Util/SDCCerr.c,
4782 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
4784 * support/regression/tests/enum.c: added test for enum values that

4787 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4789 * src/common.h: added ifndef/define/endif macros
4790 around the header file.
4791 Bug reported from Jesus Calvino-Fraga
4793 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4795 * sdcc.spec: updated
4796 * device/include/Makefile.in: don't install CVS directories
4797 * device/lib/Makefile.in: added removal of CVS directories after install
4798 * doc/Makefile: fixed install, added local_icons
4799 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4800 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4801 * src/ds390/gen.c (genRightShift): fixed bug #870788
4802 * src/SDCCast.c (decorateType): fixed bug #870781
4804 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4806 PIC16 port related changes:
4807 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4808 added variable stackPos,
4810 * gen.c: genCall, assignResultValue: added support for
4811 pushing/retrieving function parameters to/from stack,
4812 genFunction,genEndFunction: setup stack frame for the
4814 genAddrOf: will be changed according to bug 863624
4816 * added files genutils.c and genutils.h which contain gen*
4817 debugged and optimised functions extracted from gen.c
4819 * glue.c: added variable 'externs' which holds extern symbols,
4820 pic16emitRegularMap: is modified to properly handle relocatable
4821 symbols under the new scheme,
4822 pic16createInterruptVect: is modified
4823 pic16printPublics: is modified to emit 'global' assembler directives,
4824 added pic16_printExterns to print extern symbols,
4825 pic16glue: initializes stack/frame pointer in the beginning of
4826 the assembly output. Temporary hack, will be corrected later,
4827 because gplink yet does not support stack and SDCC does not
4828 yet support a type of crt0.o object to create the final binary.
4830 * Removed many lines that contain 8051 legacy code.
4831 * The code is finally placed under a 'code' directive.
4832 * Added port specific options.
4834 * _process_pragma: simplified since now we do not need *special*
4835 include file to define SFR registers. But a separate header
4836 will be needed. This will be developed later.
4837 * _pic16_parseOptions: added, parses port specific options:
4838 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4839 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4840 --preplace-udata-with=
4842 * _pic16_setDefaultOptions: modified to initialize section names,
4843 but hack is temporarly out of order since it needs improvement.
4844 * _pic16_genAssemblerPreamble: configuration words are emitted by
4845 their address instead of their name. This part is incomplete and
4846 supports only the 18Fxx2 devices. Other devices will emit an error
4847 during assembly since they do not contain the same set of config
4849 * _pic16_genIVT: is modified,
4851 * pcode.c: added definitions for some hardware registers that are needed
4853 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4854 All PCI entries are updated. Now LFSR is supported.
4855 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4856 * added pic16_newpCodeOpLit2 to support instructions with
4857 two literal arguments
4858 * pic16_pCode2str: corrected code that emits assembler instructions
4859 with two literal operands and those that have an access bit modifier
4860 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4861 this fixes a bug which caused some labels to be lost, when an
4862 assembler directive was added, i.e. banksel,
4863 * pic16_FixRegisterBanking: improved logic that causes the insertion
4865 * InlineFunction: functions that are called once, are not any more
4866 inlined. This can be a port option in the future,
4868 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4870 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4871 hold the corresponding uninitialized symbols,
4872 * pic16_allocProcessorRegister: registers have explicit marked the
4874 * pic16_allocInternalRegister: registers are explicit marked as
4876 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4877 processing list, so bit registers were lost,
4880 * ralloc.h: added field 'accessBank' and original symbol operand
4881 in register definition,
4882 * removed the field isMapped from register definition,
4884 ** Several functions have been removed from various sources:
4885 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4886 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4887 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4888 pic16_assignRelocatableRegisters
4890 ** others have been introduced:
4891 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4892 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4894 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4896 * support/scripts/inc2h.pl: changed definition of BIT_AT
4897 to emit 'sbit at' instead of 'bit at'. This was a request.
4899 PIC16 port related preliminary changes:
4900 * gen.c: prefixed function popRegFromString with
4901 pic16_ and all references to it corrected
4902 * pcode.c: all pic16_pc_* hardware registers prefixed
4903 with underscore (_),
4904 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4905 * ralloc.c: newReg(): when register is REG_SFR then
4906 set address to rIdx,
4907 pic16_allocProcessorRegister(): marks register wasUsed=0
4908 pic16_writeUsedRegs(): added a call to assign processor
4909 registers via pic16_assignFixedRegisters
4911 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4913 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4914 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4915 variables in unused register banks. Also the SSEG is placed
4916 wherever there is enough space for it, and IDATA can be anywhere
4917 in internal RAM. For now compile using -Wl-Y[stack_size].
4918 The mem file is different for this option as well, since it
4919 makes no sense of talking about DSEG lenght.
4921 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4923 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4924 in certain cases, e.g. when ROM assignment, patch provided
4925 from Albert den Haan.
4927 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
4929 Many signedness and type propagation fixes:
4930 * src/SDCCicode.c: made geniCodeCast() static
4931 replaced SPEC_ by IS_ (cosmetic)
4932 (operandOperation): fixed div and mod operation
4933 (usualBinaryConversions): added support for promotion of char
4934 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)

5930 fetching of the pointer
5931 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5932 copied from genNearPointerSet()
5933 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5934 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5935 If they pop r0/r1 they must be called in the opposite order than aopOp().
5936 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5937 (resp. --stack-auto), prepared for --xstack

5948 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5950 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5951 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5952 type for bits was changed. It resulted in bit variables becoming
5953 global, which is not permitted in PIC 14 assembly output.
5955 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5957 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5959 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5961 Z80 and MCS51 linkers complaint if a public symbol is defined

5970 A few small changes that speed up the peephole optimizer.
5974 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5976 Try to make the peephole optimizer smarter by maintaining
5977 an association between the assembly source code and the
5978 iCodes that originated them. Put this information to use
5979 with a new peephole rule condition "notVolatile" so that
5980 the rules can be aggressive yet still safe.
5985 * src/mcs51/peeph.def
5987 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5991 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5992 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5993 if the left or right operand symbols have the accuse flag set.
5995 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5997 Changed the type of the result of the ! (NOT) operator to char;
5998 previously it returned the same type as the source. This allows
5999 us to eliminate all the genFloatNot functions (all of its target
6000 implementations were very buggy) since !float can use the same
6003 * src/SDCCicode.c (ast2iCode): ! returns char
6004 * src/mcs51/gen.c (genNot, genNotFloat),
6005 * src/ds390/gen.c (genNot, genNotFloat),
6006 * src/z80/gen.c (genNot, genNotFloat),
6007 * src/pic/gen.c (genNot, genNotFloat),
6008 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6012 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6013 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6014 during interrupts. Ensure WSAVE is located at a shared bank address.
6015 2. Fixed page selection in some places
6016 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6017 the registers name strings.
6018 4. Fixed "signed / unsigned compare" compiler warnings.
6019 5. The PIC port manages its own allocation of the general purpose
6020 registers, but makes no attempt to reuse them. As a result when
6021 compiling it soon runs out of general purpose registers. Some
6022 additional code was added to the files pcode.c and device.c to walk
6023 through the function call tree and rename the registers so that they
6033 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6034 genPlus() & genMinus() when the result is the same as left or right

6040 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6042 Made bitfield a distinct type from bit so that bitfields
6043 convert as per ANSI C and bits retain their traditional
6044 boolean style behaviour. Implemented bitfield support in
6052 * src/ds390/gen.c: bit v bitfield split
6053 * src/z80/gen.c: New support for bitfields
6054 * support/regression/tests/bitfields.c: reenabled z80,
6057 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6059 Rules 246.x, 247.x relate to bitfields, the others speed up
6060 access to xdata mapped I/O devices.
6062 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6064 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6066 Cleaned up genPackBits and genUnpackBits and added two helper
6067 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6068 for literal assignments in genPackBits (thanks to Frieder for
6074 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6076 Fixed bug #748310 (pointer to function type mishandled when the
6077 function name is omitted). Also fixed a SIGSEGV when a function
6078 attribute (reentrant, etc) is used on a non-function or on a
6079 function but misplaced before the parameter list.
6081 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6083 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6106 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6108 Made the constant following the "interrupt" keyword optional. If
6109 omitted, the function will not automatically be given an entry
6110 in the interrupt vector table (similar to #pragma NOIV, but
6111 less syntacticly kludgy). The interrupt number is also now
6112 range checked. Also fixed a bug in the high order bit example

6128 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6130 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6131 be re-activated by defining REDUCE_LITERALS)
6132 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6133 unsigned, but are signed by default
6134 * src/SDCCval.c (constVal): rearranged
6135 * src/SDCCval.c (valMod): preliminary fix
6136 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6588 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6589 the regression tests I'm not brave enough to enable 245.b, 245.c
6590 * doc/sdccman.lyx: added latex preamble for hyperref package.
6591 Using pdflatex this will give you a hyperlinked pdf file with
6592 bookmarks. (prepend '%' before /usepackage if this breaks something)

6608 Applied patch from bug 737905 (renamed yylineo to mylineno):
6615 * src/pic16/pcode.c: Cleaned warnings
6616 * src/pic16/pcodeflow.c: Cleaned warnings
6617 * src/pic16/pcoderegs.c: Cleaned warnings

6630 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6632 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6633 it can be defined with CFLAGS when running configure
6634 * src/SDCCmain.c: fixed compiling + linking with object files
6636 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6639 added --disable-pic16-port
6640 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6641 * src/SDCCmain.c: linkOptions is changed to set *,
6642 added if/endif conditional macros to remove options help
6643 messages from optionsTable when a port is not configured, added
6644 support for the PIc16 port in the ports table, when executing
6645 the compiler with no port specified on command line, a default
6646 port is selected with the new macro DEFAULT_PORT which is
6647 defined in port.h, in setDefaultOptions() linkOptions is removed
6648 from initialization assignment, since now it is a set,
6649 parseCmdLine uses setParseWithComma for linkOptions, in
6650 linkEdit() linkOptions are accessed with new function indexSet()
6651 which returns the i'th item of a set variable. See SDCCset.c, in
6652 linkEdit() when calling buildCmdLine(), added linkOptions as
6653 last argument. Now users can pass arguments to gplink via the
6654 -Wl option, main() uses pic16glue() to glue up pic16 programs

6666 * src/pic16/glue.c: commented out some error producing lines
6667 * src/pic16/main.c: __config directives are commented out to stop
6668 gpasm complaining and test the linkage with gplink, _linkCmd and
6669 _asmCmd changed to be more gplink and gpasm friendly
6670 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6671 produced an error when parsed, peep rule 12 is added to utilize
6672 movff, but it is commented out since the pCode does not support
6673 yet a command with 2 address arguments
6675 2003-05-18 <johan AT balder>
6677 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6678 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6702 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6704 2003-05-11 Borut Razem <borut.razem AT siol.net>
6706 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6707 the path of bin directory, so that PATH is the only env. variable, which has to be set
6708 in case of standard installation.

7738 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7740 * in \sdcc\as\mcs51\ changed these files in order to create an
7741 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7742 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7743 following files to include the previous two files: aslink.dsp,
7744 Makefile.aslink, Makefile.bcc, and Makefile.in.
7746 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7747 .adb instead of .cdb
7749 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7751 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7752 value from option --iram-size.
7754 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7756 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7759 2002-09-18 <wiml AT hhhh.org>
7761 * SDCClrange.h: exposed setFromRange() and setToRange()
7762 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7763 packRegsForAccUse() (bug 542397)
7764 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7765 multiple times and emitting the fetch operations more than once
7766 added aopGetUsesAcc() function to allow binary operators to
7767 fetch their operands in the correct order; made genMinus() emit
7768 compact code for X = LITERAL - Y
7770 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7771 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7772 sprintf() in line 1267.
7774 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7775 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7778 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7779 Changes to aslink (All the changes are marked with 'JCF'):
7781 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7784 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7785 area BSEG. Also moves, if possible, the DATA area down into the internal
7786 ram so more space is available.
7788 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7791 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7792 not bytes. Function summary() which creates a memory usage summary
7793 file with extension .mem. Reports of overlaping stack and small stack
7794 size. If the space for the stack is less than 16 bytes aslink trows a
7797 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7798 the 8051. Option 'y' for memory summary output file.
7800 Changes to sdcc (All the changes are marked with 'JCF'):
7802 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7804 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7805 overlaying area for it (uses RegBankUsed[4]).
7807 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7808 bank zero as used by default. By default aslink locates the stack
7809 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7810 the creation of the .mem file. Delegates the allocation of data area
7811 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7812 the begining of the stack area to aslink.
7814 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7815 glue() in SDCCglue.c creates an area for it.
7817 2002-09-03 Borut Razem <borut.razem AT siol.net>
7818 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7819 sdcc/src/pic/glue.c:
7820 introduced atexit() handler for teporay files removal in case of
7821 errors, assertions, ...
7823 2002-08-29 Borut Razem <borut.razem AT siol.net>
7824 * sdcc/support/cpp2/auto-host_vc_in.h:
7825 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7826 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7827 Maybe there is a similar problem with BORLANDC? It should be checked!
7829 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7830 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7831 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7832 was not executed, and the compiler (cl) launched a warning:
7833 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7835 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7836 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7838 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7845 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7846 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7847 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7848 - added Release configuration in VS projects
7849 - review of compiler an linker options
7850 - VC .exe files are generated in bin_vc directory, not to interfere
7851 with binaries generated from other projects (cygwin, mingw, bcc ...)
7853 * sdcc/src/yacc.dsp: added
7855 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7856 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7857 and insert the version number definitions from .version
7859 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7861 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7868 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7870 2002-08-11 Borut Razem <borut.razem AT siol.net>
7871 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7873 2002-08-10 Borut Razem <borut.razem AT siol.net>
7874 * src/SDCCmain.c (main):
7875 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7876 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7877 The consequence was that some temporary files were not removed.
7880 unification of code in functions tempfilename() and tempfile():
7881 function tempnam() is defined in Visual Studio 6.0 and .NET
7883 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7885 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7886 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7887 - removed compiler command line option /WX: Treats all warnings as errors
7888 - update a list of source files, included into the project
7890 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

7900 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7901 added return 0 statements after assert() to make compiler happy
7903 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7904 added newline in the def file to keep MSC compiler satisfied
7906 * sdcc/src/z80/gen.c:
7907 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7908 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7909 - solved MSC error in function aopDump()
7911 * sdcc_vc.h: define PREFIX as "\\sdcc"
7913 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7969 were not getting allocated.
7971 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7974 Fixed left shift. Will promote the left side of a left shift
7975 if a) left shifting more than size of operand or b) when assigned
7976 to something size > size of left side
7978 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8088 * sdcc/src/SDCCloop.c:
8089 Previous fix was not good. basic blocks that have "break" or "return" are
8090 not really partof a loop , but live ranges used in these blocks should
8091 be live thru the entire loop, so set partOfLoop but don't add them to
8094 2002-02-21 <johan AT FRIJA>
