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

654 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
656 * device/lib/printf_large.c: removed inline assembly for portability and
657 readability. Use printf_fast if speed or size are more important.
658 * src/pic16/gen.c: removed conditions around use of DEBUGpc
659 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
661 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
663 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
664 prevent compiler warning
666 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
668 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
669 moved to level 0 and declared as static. Also they are explicit
670 placed in access bank. This was necessery because some times they
671 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
672 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
673 optimizations. Currently only compare to unsigned char is implemented,
674 * src/pic16/gen.c: added fReturnIdx array,
675 * (struct resolvedIfx) is moved to gen.h and made public,
676 * (struct _G): added sregsAlloc and sregsAllocSet fields,
677 * (aopForSym): added an optimization to directly store in stack of
678 the operand of a SEND iCode,
679 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
680 but as registers instead (AOP_REG) using the fReturnIdx array,
681 * (pic16_freeAsmop): remove the freed register from the
683 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
685 * (pic16_popGetTempRegCond): changed function prototype, now
686 function takes also a bitVector argument v which holds the current
687 set of registers that are allocated for stack access by aopForSym,
688 registers allocated in aopForSym for accessing stack symbols are not
689 any more part of the functions usedRegs field,
690 * (genCall): some times aopOp is called for a stack variable to be
691 send, aopForSym might perform the push, if this is true make sure
692 that genCall doesn't push the variable twice by testing _G.resDirect,
693 * (genFunction): changed testing for unspecified interrupt number
694 from 256 to INTNO_UNSPEC,
695 * modified selection scheme of frame pointer generation. Previously
696 if function did use local registers a frame pointer was generated,
697 now a frame pointer is generated only if function has arguments
698 (that need PLUSW2 register access), or has stack arguments, or the
699 compiler is not instructed to omit the frame pointer,
700 * (genEndFunction): before restoring local registers that were saved
701 in the function preamble, also restore the registers that *might*
702 have been allocated for stack access,
703 * (genRet): removed some old comments,
704 * (genCmp, the active (RN's) version): added a call to the
705 pic16_genCmp_special function to perform the compare with a more
706 robust and optimized way,
707 * (genInline): a feature has been added in inline code generation,
708 which allows a wildcard variable substitution when writing inline
709 assembly. Code is incomplete and experimental therefore undocumented,
710 * (genCast): changed order of aopOp for result and right to allow
711 aopForSym to directly load the result if possible,
712 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
713 perform an optimized compare on some selected special occasions,
714 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
715 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
716 generate an IVT any more,
717 * src/pic16/main.c (pic16_optionsTable): added command line option
719 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
720 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
722 * src/pic16/NOTES: Raphael Neider added in list of active developers
723 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
724 jumptable_end to prevent bug #,
725 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
726 inCond and outCond fields,
727 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
728 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
729 turn off register spilling,
730 * (packRegsForOneUse): synced with other ports' versions although it
731 is not used currently,
732 * (pic16_packRegisters): added an optimization while reading
733 structure bitfields, some registers may be saved (malloc code is
734 decreased by 80 bytes)
736 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
738 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
739 left is a bitfield, if yes, then don't optimize assignment. Perhaps
740 this can be optimized more?
742 2005-03-10 Raphael Neider <rneider AT web.de>
744 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
745 genNearPointerGet): (hopefully) fixed access to bitfields via
746 pointers (p->bitN = x; and x = p->bitN; failed)
748 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
750 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

1363 (setFromConditionArgs): friendly operand parser for peephole rules,
1364 (operandBaseName, operandsNotRelated): new peephole condition
1365 "operandsNotRelated" -- similar to "operandsNotSame", but takes

1378 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1380 Adding support for replacing ljmps with sjmps in jumptables
1381 generated for switch statements. For now you need to set the
1382 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1383 Now 4 algorithms for mcs51 jumptable generation are used:
1384 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1385 addresses loaded pc-relative for up to 112 cases and stack-pushing
1386 target addresses loaded with offset from dptr for up to 256 cases.
1388 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1389 * src/mcs51/main.c: adapted constants for switch table generation
1390 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1412 Large cummulative patch for pic16 port.
1413 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1414 to call when a stack overflow occurs,
1415 * (malloc.h): added CVS Id tag,
1416 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1418 * added libc directory. The current version of LibC contains string
1419 functions, ctype functions and macros and some functions of the
1420 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1421 be extensively tested in the future. Standard disclaimer here.
1422 Library is not automatically build yet. But one can build it by
1423 invoking 'make' inside the libc directory.
1424 * added ADC library under libio. Preliminary version yet.
1426 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1433 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1434 * (pic16_storeForReturn): optimized return of 0,
1435 * (genCmp): experimental code for new genCmp which uses PIC18's
1436 special compare&skip instructions. Initial tests fail some times
1437 with variables grater than 1 byte in size, so new code is disabled,
1438 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1440 * (genCast): began a fix to optimize the casting of a bit to another
1441 bit, now assigning a bitfield to another bitfield will fail, sorry,
1442 * src/pic16/main.c: disabled the use of lr-support feature,
1443 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1444 * added some function prototypes, added function _debugf prototype,

1446 bits with offset (case PO_GPR_BIT),
1447 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1449 * (isBankInstruction): modified to return 0 for no banking instruction,
1450 and 1 for banking instruction,
1451 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1452 caused stop processing pCodes after a inline assembly block,
1453 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1454 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1455 registers when it shouldn't,
1456 * src/pic16/ralloc.c (allocReg): add preliminary support for
1457 supporting a limited set of temporary registers,
1459 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1461 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1462 genDataPointerSet): ensure assignments always copy in MSB to LSB
1464 (loadRegFromAop): recognize CLRH optimization,
1465 (genFunction): optimize RECEIVE iCodes in reentrant functions
1467 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1469 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1470 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1472 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1481 instead of sjmp to ret
1482 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1483 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1485 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4464 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4466 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4467 loaded with the linker search paths (-L arguments) and the libraries
4468 to be linked with the current source (-l arguments). Changes
4469 currently will affect only the pic16 port.
4470 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4471 include path the port specific paths and port specific libraries,
4472 * gplink command now contains the $3 argument,
4473 * src/pic16/device.h,
4474 * src/pic16/device.c,: structure PIC_device is made public and
4475 renamed to PIC16_device, the same for variable Pics which is renamed
4476 to Pics16. Updated all references to them.
4477 * src/pic16/glue.c (pic16glue): corrected bug with code
4478 initialization which bypassed the variable initializations block.

4488 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4490 Documenting changes from previous commits.
4491 * configure.in (version 1.56),
4492 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4493 when generating output files to configure the pic16 library,
4494 but now I've commented it out, since gputils aren't installed in the
4495 SF compile farm, so library won't compile
4497 * device/lib/Makefile.in (version 1.56): initially I've added in
4498 target 'all' the prerequestive 'model-pic16' so it compiled the
4499 pic16 library, but now I've commented it out for the same reasons
4501 * added targets 'model-pic16' and 'objects-pic16' to compile the
4503 * added target 'port-specific-objects-pic16' to handle the
4504 generated libraries and copy them into the build/ directory
4505 * added target 'clean-intermediate-pic16' to clean intermediate
4506 files into pic16 directory
4507 * in target 'installdirs' added line to create directory pic16 in
4508 the installation path
4510 * device/include/Makefile.in (version 1.11): in target 'install'
4511 added lines to copy all header files to installation path,
4512 * in target 'installdirs' added line create directory for pic16
4513 headers in the installation path
4515 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4528 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4529 option so that it actually works. Made it specific to the z80, since
4530 the gbz80 doesn't have these kinds of I/O ports.
4532 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4534 * device/include/z180.h,

4541 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
4542 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4543 portmode; added deprecation warning for bank= and protmode= forms.
4544 Also, guard against buffer overflow.
4545 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4547 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4549 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4550 changed interrupt vector table generation to only emit declared vectors.
4551 * device/include/Makefile.in: added missing backslash
4552 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4554 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4556 Mainly changes to support compilation of the device libraries
4557 * src/pic16/device.c: stack is allocated via symbol and not
4558 via literal number. The symbol is placed in the corresponding
4559 position of the data ram
4560 * (pic16_dump_section): relocatable and absolute uninitialized
4561 data are now emitted in sorted order to reduce section naming,
4562 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4563 weren't marked as being in the access bank,
4565 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4567 Added portion of GNU PIC Library under the directory
4568 device/include/pic16 and device/lib/pic16. These files
4569 contain the declarations of SFRs for the PIC18Fxx2 devices.
4570 The directory is initialized via configure from toplevel.
4572 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4574 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4575 the spilllocations to be compared correctly
4577 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4579 * src/SDCCast.c (decorateType): fixed bug introduced today
4581 2004-01-12 Borut Razem <borut.razem AT siol.net>
4583 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4586 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4588 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4589 in simpler and even better code
4591 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4593 * src/SDCCicode.c (operandOperation): fixed bug #874819

4597 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4599 * doc/sdccman.lyx: Moved and added some sections, small changes
4600 all over. Telling LaTeX to be less strict with word spacing
4601 to better keep the right margin. Changed some notes about
4602 maintainance of the ports in section 3.2.1 - is it OK like this?
4604 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4606 SDCC source changes:
4607 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4640 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4641 UPPER for immediate operands,
4642 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4644 * src/pic16/peeph.def: all peepholes with movff are commented out,
4645 because there is a problem in the pcode peep optimizer,
4646 * src/pic16/ralloc.c: the register allocator can now reuse local
4647 function symbols for another function. This saves register usage.
4648 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4650 Added file src/pic16/NOTES with information about program writing on
4651 the current port version.

4660 * src/SDCCmain.c : fixed #872250: -l command line defined library
4661 files are scanned before standard library files
4663 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4680 gen51Code): more efficient parameter receive for --model-large
4683 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4686 * src/z80/main.c: added missed needLinkerScript flags (more than
4687 one port structure defined in these file)
4688 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
4691 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

4704 needLinkerScript flag
4706 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4707 * src/pic/glue.c: added variable udata_section_name to
4708 override default uninitialized data segment definition for
4709 devices only with SHAREBANK memory (reported from Erik Epetrich)
4710 * (pic14emitOverlay): modified to emit a commented overlay segment
4711 directive when no overlay data exist
4712 * (picglue): modified to emit uninitialized data segment
4713 according to udata_section_name
4714 * src/pic/main.c (_pic14_parseOptions): added command line

4718 arguments via -W option
4719 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4720 object file from '.rel' to '.o' in port->linker structure,
4721 changed size of fptr from 2 to 3 in port structure
4723 2004-01-07 Borut Razem <borut.razem AT siol.net>
4725 * support/scripts/sdcc.nsi: update PATH
4726 * support/scripts/sdcc.ico: craeted
4728 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4730 * device/include/Makefile.in: fix install
4731 * doc/Makefile: fix install
4733 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4735 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4737 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4738 how the function variable allocation summary is displayed; also
4739 include information about variables allocated to the overlay
4742 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4744 * as/mcs51/lkmain.c: Help about -Y option

4756 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4758 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4759 (default behaviour).
4761 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4763 A python script to validate compiler diagnostic messages. It can be
4764 used to verify that sdcc complains about bad c source code and
4765 gives a good location of the error.
4766 * support/valdiag/Makefile,
4767 * support/valdiag/valdiag.py,
4768 * support/valdiag/tests/*
4770 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4772 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4773 * src/SDCCsymt.c (newEnumType),
4775 * support/Util/SDCCerr.c,

4781 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4783 * src/common.h: added ifndef/define/endif macros
4784 around the header file.
4785 Bug reported from Jesus Calvino-Fraga
4787 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4789 * sdcc.spec: updated
4790 * device/include/Makefile.in: don't install CVS directories
4791 * device/lib/Makefile.in: added removal of CVS directories after install
4792 * doc/Makefile: fixed install, added local_icons
4793 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4794 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4795 * src/ds390/gen.c (genRightShift): fixed bug #870788
4796 * src/SDCCast.c (decorateType): fixed bug #870781
4798 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4800 PIC16 port related changes:
4801 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4802 added variable stackPos,
4804 * gen.c: genCall, assignResultValue: added support for
4805 pushing/retrieving function parameters to/from stack,
4806 genFunction,genEndFunction: setup stack frame for the
4808 genAddrOf: will be changed according to bug 863624
4810 * added files genutils.c and genutils.h which contain gen*
4811 debugged and optimised functions extracted from gen.c
4813 * glue.c: added variable 'externs' which holds extern symbols,
4814 pic16emitRegularMap: is modified to properly handle relocatable
4815 symbols under the new scheme,
4816 pic16createInterruptVect: is modified
4817 pic16printPublics: is modified to emit 'global' assembler directives,
4818 added pic16_printExterns to print extern symbols,
4819 pic16glue: initializes stack/frame pointer in the beginning of
4820 the assembly output. Temporary hack, will be corrected later,
4821 because gplink yet does not support stack and SDCC does not
4822 yet support a type of crt0.o object to create the final binary.
4824 * Removed many lines that contain 8051 legacy code.
4825 * The code is finally placed under a 'code' directive.
4826 * Added port specific options.
4828 * _process_pragma: simplified since now we do not need *special*
4829 include file to define SFR registers. But a separate header
4830 will be needed. This will be developed later.
4831 * _pic16_parseOptions: added, parses port specific options:
4832 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4833 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4834 --preplace-udata-with=
4836 * _pic16_setDefaultOptions: modified to initialize section names,
4837 but hack is temporarly out of order since it needs improvement.
4838 * _pic16_genAssemblerPreamble: configuration words are emitted by
4839 their address instead of their name. This part is incomplete and
4840 supports only the 18Fxx2 devices. Other devices will emit an error
4841 during assembly since they do not contain the same set of config
4843 * _pic16_genIVT: is modified,
4845 * pcode.c: added definitions for some hardware registers that are needed
4847 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4848 All PCI entries are updated. Now LFSR is supported.
4849 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4850 * added pic16_newpCodeOpLit2 to support instructions with
4851 two literal arguments
4852 * pic16_pCode2str: corrected code that emits assembler instructions
4853 with two literal operands and those that have an access bit modifier
4854 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4855 this fixes a bug which caused some labels to be lost, when an
4856 assembler directive was added, i.e. banksel,
4857 * pic16_FixRegisterBanking: improved logic that causes the insertion
4859 * InlineFunction: functions that are called once, are not any more
4860 inlined. This can be a port option in the future,
4862 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4864 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4865 hold the corresponding uninitialized symbols,
4866 * pic16_allocProcessorRegister: registers have explicit marked the
4868 * pic16_allocInternalRegister: registers are explicit marked as
4870 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4871 processing list, so bit registers were lost,
4874 * ralloc.h: added field 'accessBank' and original symbol operand
4875 in register definition,
4876 * removed the field isMapped from register definition,
4878 ** Several functions have been removed from various sources:
4879 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4880 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4881 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4882 pic16_assignRelocatableRegisters
4884 ** others have been introduced:
4885 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4886 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4888 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4890 * support/scripts/inc2h.pl: changed definition of BIT_AT
4891 to emit 'sbit at' instead of 'bit at'. This was a request.
4893 PIC16 port related preliminary changes:
4894 * gen.c: prefixed function popRegFromString with
4895 pic16_ and all references to it corrected
4896 * pcode.c: all pic16_pc_* hardware registers prefixed
4897 with underscore (_),
4898 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4899 * ralloc.c: newReg(): when register is REG_SFR then
4900 set address to rIdx,
4901 pic16_allocProcessorRegister(): marks register wasUsed=0
4902 pic16_writeUsedRegs(): added a call to assign processor
4903 registers via pic16_assignFixedRegisters
4905 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4907 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4908 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4909 variables in unused register banks. Also the SSEG is placed
4910 wherever there is enough space for it, and IDATA can be anywhere
4911 in internal RAM. For now compile using -Wl-Y[stack_size].
4912 The mem file is different for this option as well, since it
4913 makes no sense of talking about DSEG lenght.
4915 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4917 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4918 in certain cases, e.g. when ROM assignment, patch provided
4919 from Albert den Haan.
4921 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
4923 Many signedness and type propagation fixes:
4924 * src/SDCCicode.c: made geniCodeCast() static
4925 replaced SPEC_ by IS_ (cosmetic)
4926 (operandOperation): fixed div and mod operation
4927 (usualBinaryConversions): added support for promotion of char
4928 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
4929 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
4930 (geniCodeAdd): an array index will stay unsigned, even if promoted

5927 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5928 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5929 If they pop r0/r1 they must be called in the opposite order than aopOp().
5930 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5931 (resp. --stack-auto), prepared for --xstack

5940 these ports have their own __sdcc_external_start()
5942 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5944 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5945 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5946 type for bits was changed. It resulted in bit variables becoming
5947 global, which is not permitted in PIC 14 assembly output.
5949 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5951 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5953 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5955 Z80 and MCS51 linkers complaint if a public symbol is defined

5964 A few small changes that speed up the peephole optimizer.
5968 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5970 Try to make the peephole optimizer smarter by maintaining
5971 an association between the assembly source code and the
5972 iCodes that originated them. Put this information to use
5973 with a new peephole rule condition "notVolatile" so that
5974 the rules can be aggressive yet still safe.
5979 * src/mcs51/peeph.def
5981 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5985 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5986 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5987 if the left or right operand symbols have the accuse flag set.
5989 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5991 Changed the type of the result of the ! (NOT) operator to char;
5992 previously it returned the same type as the source. This allows
5993 us to eliminate all the genFloatNot functions (all of its target
5994 implementations were very buggy) since !float can use the same
5997 * src/SDCCicode.c (ast2iCode): ! returns char
5998 * src/mcs51/gen.c (genNot, genNotFloat),
5999 * src/ds390/gen.c (genNot, genNotFloat),
6000 * src/z80/gen.c (genNot, genNotFloat),
6001 * src/pic/gen.c (genNot, genNotFloat),
6002 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

6006 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6007 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6008 during interrupts. Ensure WSAVE is located at a shared bank address.
6009 2. Fixed page selection in some places
6010 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6011 the registers name strings.
6012 4. Fixed "signed / unsigned compare" compiler warnings.
6013 5. The PIC port manages its own allocation of the general purpose
6014 registers, but makes no attempt to reuse them. As a result when
6015 compiling it soon runs out of general purpose registers. Some
6016 additional code was added to the files pcode.c and device.c to walk
6017 through the function call tree and rename the registers so that they
6027 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6034 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6036 Made bitfield a distinct type from bit so that bitfields
6037 convert as per ANSI C and bits retain their traditional
6038 boolean style behaviour. Implemented bitfield support in
6046 * src/ds390/gen.c: bit v bitfield split
6047 * src/z80/gen.c: New support for bitfields
6048 * support/regression/tests/bitfields.c: reenabled z80,
6051 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6053 Rules 246.x, 247.x relate to bitfields, the others speed up
6054 access to xdata mapped I/O devices.
6056 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6058 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6060 Cleaned up genPackBits and genUnpackBits and added two helper
6061 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6062 for literal assignments in genPackBits (thanks to Frieder for
6068 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6070 Fixed bug #748310 (pointer to function type mishandled when the
6071 function name is omitted). Also fixed a SIGSEGV when a function
6072 attribute (reentrant, etc) is used on a non-function or on a
6073 function but misplaced before the parameter list.
6075 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6077 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6100 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6102 Made the constant following the "interrupt" keyword optional. If
6103 omitted, the function will not automatically be given an entry
6104 in the interrupt vector table (similar to #pragma NOIV, but
6105 less syntacticly kludgy). The interrupt number is also now
6106 range checked. Also fixed a bug in the high order bit example

6122 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6124 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6125 be re-activated by defining REDUCE_LITERALS)
6126 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6127 unsigned, but are signed by default
6128 * src/SDCCval.c (constVal): rearranged
6129 * src/SDCCval.c (valMod): preliminary fix
6130 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6582 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6583 the regression tests I'm not brave enough to enable 245.b, 245.c
6584 * doc/sdccman.lyx: added latex preamble for hyperref package.
6585 Using pdflatex this will give you a hyperlinked pdf file with
6586 bookmarks. (prepend '%' before /usepackage if this breaks something)

6600 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
6602 Applied patch from bug 737905 (renamed yylineo to mylineno):
6609 * src/pic16/pcode.c: Cleaned warnings
6610 * src/pic16/pcodeflow.c: Cleaned warnings
6611 * src/pic16/pcoderegs.c: Cleaned warnings

6624 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6626 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6627 it can be defined with CFLAGS when running configure
6628 * src/SDCCmain.c: fixed compiling + linking with object files
6630 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6632 * configure.in: configure for pic16 port,
6633 added --disable-pic16-port
6634 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6635 * src/SDCCmain.c: linkOptions is changed to set *,
6636 added if/endif conditional macros to remove options help
6637 messages from optionsTable when a port is not configured, added
6638 support for the PIc16 port in the ports table, when executing
6639 the compiler with no port specified on command line, a default
6640 port is selected with the new macro DEFAULT_PORT which is
6641 defined in port.h, in setDefaultOptions() linkOptions is removed
6642 from initialization assignment, since now it is a set,
6643 parseCmdLine uses setParseWithComma for linkOptions, in
6644 linkEdit() linkOptions are accessed with new function indexSet()
6645 which returns the i'th item of a set variable. See SDCCset.c, in
6646 linkEdit() when calling buildCmdLine(), added linkOptions as
6647 last argument. Now users can pass arguments to gplink via the
6648 -Wl option, main() uses pic16glue() to glue up pic16 programs
6649 * src/SDCCpeeph.c: various changes to support pic16

6660 * src/pic16/glue.c: commented out some error producing lines
6661 * src/pic16/main.c: __config directives are commented out to stop
6662 gpasm complaining and test the linkage with gplink, _linkCmd and
6663 _asmCmd changed to be more gplink and gpasm friendly
6664 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6665 produced an error when parsed, peep rule 12 is added to utilize
6666 movff, but it is commented out since the pCode does not support
6667 yet a command with 2 address arguments
6669 2003-05-18 <johan AT balder>
6671 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6672 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6673 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

6696 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6698 2003-05-11 Borut Razem <borut.razem AT siol.net>
6700 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6701 the path of bin directory, so that PATH is the only env. variable, which has to be set
6702 in case of standard installation.
6703 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7732 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7734 * in \sdcc\as\mcs51\ changed these files in order to create an
7735 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7736 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7737 following files to include the previous two files: aslink.dsp,
7738 Makefile.aslink, Makefile.bcc, and Makefile.in.
7740 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7741 .adb instead of .cdb
7743 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7745 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7746 value from option --iram-size.
7748 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7750 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7753 2002-09-18 <wiml AT hhhh.org>
7755 * SDCClrange.h: exposed setFromRange() and setToRange()
7756 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7757 packRegsForAccUse() (bug 542397)
7758 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7759 multiple times and emitting the fetch operations more than once
7760 added aopGetUsesAcc() function to allow binary operators to
7761 fetch their operands in the correct order; made genMinus() emit
7762 compact code for X = LITERAL - Y
7764 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7765 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7766 sprintf() in line 1267.
7768 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7769 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7772 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7773 Changes to aslink (All the changes are marked with 'JCF'):
7775 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7778 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7779 area BSEG. Also moves, if possible, the DATA area down into the internal
7780 ram so more space is available.
7782 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7785 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7786 not bytes. Function summary() which creates a memory usage summary
7787 file with extension .mem. Reports of overlaping stack and small stack
7788 size. If the space for the stack is less than 16 bytes aslink trows a
7791 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7792 the 8051. Option 'y' for memory summary output file.
7794 Changes to sdcc (All the changes are marked with 'JCF'):
7796 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7798 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7799 overlaying area for it (uses RegBankUsed[4]).
7801 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7802 bank zero as used by default. By default aslink locates the stack
7803 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7804 the creation of the .mem file. Delegates the allocation of data area
7805 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7806 the begining of the stack area to aslink.
7808 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7809 glue() in SDCCglue.c creates an area for it.
7811 2002-09-03 Borut Razem <borut.razem AT siol.net>
7812 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7813 sdcc/src/pic/glue.c:
7814 introduced atexit() handler for teporay files removal in case of
7815 errors, assertions, ...
7817 2002-08-29 Borut Razem <borut.razem AT siol.net>
7818 * sdcc/support/cpp2/auto-host_vc_in.h:
7819 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7820 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7821 Maybe there is a similar problem with BORLANDC? It should be checked!
7823 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7824 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7825 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7826 was not executed, and the compiler (cl) launched a warning:
7827 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7829 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7830 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7832 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7839 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7840 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7841 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7842 - added Release configuration in VS projects
7843 - review of compiler an linker options
7844 - VC .exe files are generated in bin_vc directory, not to interfere
7845 with binaries generated from other projects (cygwin, mingw, bcc ...)
7847 * sdcc/src/yacc.dsp: added
7849 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7850 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7851 and insert the version number definitions from .version
7853 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7855 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7859 removed from CVS, generated automatically
7861 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7862 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7864 2002-08-11 Borut Razem <borut.razem AT siol.net>
7865 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7867 2002-08-10 Borut Razem <borut.razem AT siol.net>
7868 * src/SDCCmain.c (main):
7869 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7870 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7871 The consequence was that some temporary files were not removed.
7874 unification of code in functions tempfilename() and tempfile():
7875 function tempnam() is defined in Visual Studio 6.0 and .NET
7877 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7879 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7880 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7881 - removed compiler command line option /WX: Treats all warnings as errors
7882 - update a list of source files, included into the project
7884 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7885 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7886 changed project type to Generic Project so that can be correcly converted to VS.NET project
7888 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7890 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7894 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7895 added return 0 statements after assert() to make compiler happy
7897 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7898 added newline in the def file to keep MSC compiler satisfied
7900 * sdcc/src/z80/gen.c:
7901 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7902 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7903 - solved MSC error in function aopDump()
7905 * sdcc_vc.h: define PREFIX as "\\sdcc"
7907 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7959 Initialized the new field char *Processor field to NULL in all ports
7962 Compiler generated registers for interrupt context saving
7963 were not getting allocated.
7965 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7968 Fixed left shift. Will promote the left side of a left shift
7969 if a) left shifting more than size of operand or b) when assigned
7970 to something size > size of left side
7972 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7974 tons of changes. Register allocation has been
7975 rewritten. Added customization for the various PICs. Flow

8080 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8082 * sdcc/src/SDCCloop.c:
8083 Previous fix was not good. basic blocks that have "break" or "return" are
8084 not really partof a loop , but live ranges used in these blocks should
8085 be live thru the entire loop, so set partOfLoop but don't add them to
8088 2002-02-21 <johan AT FRIJA>
8090 * src/SDCCcse.c: fixed bug #514308
8092 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8117 Karl and Johan start ucsim XA support. Most dissassembly working,
8118 about 75% emulation done(plenty of work remaining).
8120 * sim/ucsim/z80.src:
8121 Add Z80 support to ucsim, add test-ucz80 regression test,
8122 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
