482 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
483 on rIfx (genCmp was broken)
485 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
487 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
488 * src/z80/main.c (_keywords[]),
489 * src/SDCCglobal.h (struct options),
491 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
492 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
493 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
494 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
495 always available in leading double underscore form. The C99 support is
496 mostly missing, but it's a start.
497 * support/regression/tests/bug-227710.c: fixed nonconforming use of
498 reserved identifier "__data".
500 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

546 2005-03-20 Borut Razem <borut.razem AT siol.net>
548 * support/scripts/inc2h.pl: WIN32 port

574 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
576 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
578 * device/lib/printf_large.c: removed inline assembly for portability and
579 readability. Use printf_fast if speed or size are more important.
580 * src/pic16/gen.c: removed conditions around use of DEBUGpc
581 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
583 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
585 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
586 prevent compiler warning
588 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
590 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
591 moved to level 0 and declared as static. Also they are explicit
592 placed in access bank. This was necessery because some times they
593 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
594 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
595 optimizations. Currently only compare to unsigned char is implemented,
596 * src/pic16/gen.c: added fReturnIdx array,
597 * (struct resolvedIfx) is moved to gen.h and made public,
598 * (struct _G): added sregsAlloc and sregsAllocSet fields,
599 * (aopForSym): added an optimization to directly store in stack of
600 the operand of a SEND iCode,
601 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
602 but as registers instead (AOP_REG) using the fReturnIdx array,
603 * (pic16_freeAsmop): remove the freed register from the
605 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
607 * (pic16_popGetTempRegCond): changed function prototype, now
608 function takes also a bitVector argument v which holds the current
609 set of registers that are allocated for stack access by aopForSym,
610 registers allocated in aopForSym for accessing stack symbols are not
611 any more part of the functions usedRegs field,
612 * (genCall): some times aopOp is called for a stack variable to be
613 send, aopForSym might perform the push, if this is true make sure
614 that genCall doesn't push the variable twice by testing _G.resDirect,
615 * (genFunction): changed testing for unspecified interrupt number
616 from 256 to INTNO_UNSPEC,
617 * modified selection scheme of frame pointer generation. Previously
618 if function did use local registers a frame pointer was generated,
619 now a frame pointer is generated only if function has arguments
620 (that need PLUSW2 register access), or has stack arguments, or the
621 compiler is not instructed to omit the frame pointer,
622 * (genEndFunction): before restoring local registers that were saved
623 in the function preamble, also restore the registers that *might*
624 have been allocated for stack access,
625 * (genRet): removed some old comments,
626 * (genCmp, the active (RN's) version): added a call to the
627 pic16_genCmp_special function to perform the compare with a more
628 robust and optimized way,
629 * (genInline): a feature has been added in inline code generation,
630 which allows a wildcard variable substitution when writing inline
631 assembly. Code is incomplete and experimental therefore undocumented,
632 * (genCast): changed order of aopOp for result and right to allow
633 aopForSym to directly load the result if possible,
634 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
635 perform an optimized compare on some selected special occasions,
636 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
637 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
638 generate an IVT any more,
639 * src/pic16/main.c (pic16_optionsTable): added command line option
641 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
642 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
644 * src/pic16/NOTES: Raphael Neider added in list of active developers
645 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
646 jumptable_end to prevent bug #,
647 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
648 inCond and outCond fields,
649 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
650 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
651 turn off register spilling,
652 * (packRegsForOneUse): synced with other ports' versions although it
653 is not used currently,
654 * (pic16_packRegisters): added an optimization while reading
655 structure bitfields, some registers may be saved (malloc code is
656 decreased by 80 bytes)
658 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
660 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
661 left is a bitfield, if yes, then don't optimize assignment. Perhaps
662 this can be optimized more?
664 2005-03-10 Raphael Neider <rneider AT web.de>
666 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
667 genNearPointerGet): (hopefully) fixed access to bitfields via
668 pointers (p->bitN = x; and x = p->bitN; failed)

4386 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4388 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4389 loaded with the linker search paths (-L arguments) and the libraries
4390 to be linked with the current source (-l arguments). Changes
4391 currently will affect only the pic16 port.
4392 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4393 include path the port specific paths and port specific libraries,
4394 * gplink command now contains the $3 argument,
4395 * src/pic16/device.h,
4396 * src/pic16/device.c,: structure PIC_device is made public and
4397 renamed to PIC16_device, the same for variable Pics which is renamed

4412 Documenting changes from previous commits.
4413 * configure.in (version 1.56),
4414 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4415 when generating output files to configure the pic16 library,
4416 but now I've commented it out, since gputils aren't installed in the
4417 SF compile farm, so library won't compile
4419 * device/lib/Makefile.in (version 1.56): initially I've added in
4420 target 'all' the prerequestive 'model-pic16' so it compiled the
4421 pic16 library, but now I've commented it out for the same reasons
4423 * added targets 'model-pic16' and 'objects-pic16' to compile the
4425 * added target 'port-specific-objects-pic16' to handle the
4426 generated libraries and copy them into the build/ directory
4427 * added target 'clean-intermediate-pic16' to clean intermediate
4428 files into pic16 directory
4429 * in target 'installdirs' added line to create directory pic16 in
4430 the installation path
4432 * device/include/Makefile.in (version 1.11): in target 'install'
4433 added lines to copy all header files to installation path,
4434 * in target 'installdirs' added line create directory for pic16
4435 headers in the installation path

4450 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4451 option so that it actually works. Made it specific to the z80, since
4452 the gbz80 doesn't have these kinds of I/O ports.

4480 via literal number. The symbol is placed in the corresponding
4481 position of the data ram
4482 * (pic16_dump_section): relocatable and absolute uninitialized
4483 data are now emitted in sorted order to reduce section naming,
4484 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4485 weren't marked as being in the access bank,
4487 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4489 Added portion of GNU PIC Library under the directory
4490 device/include/pic16 and device/lib/pic16. These files
4491 contain the declarations of SFRs for the PIC18Fxx2 devices.
4492 The directory is initialized via configure from toplevel.
4494 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4496 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4521 * doc/sdccman.lyx: Moved and added some sections, small changes
4522 all over. Telling LaTeX to be less strict with word spacing
4523 to better keep the right margin. Changed some notes about
4524 maintainance of the ports in section 3.2.1 - is it OK like this?
4526 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4564 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4566 * src/pic16/peeph.def: all peepholes with movff are commented out,
4567 because there is a problem in the pcode peep optimizer,
4568 * src/pic16/ralloc.c: the register allocator can now reuse local

4602 gen51Code): more efficient parameter receive for --model-large
4605 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4608 * src/z80/main.c: added missed needLinkerScript flags (more than
4609 one port structure defined in these file)
4610 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4626 needLinkerScript flag
4628 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4629 * src/pic/glue.c: added variable udata_section_name to
4630 override default uninitialized data segment definition for
4631 devices only with SHAREBANK memory (reported from Erik Epetrich)
4632 * (pic14emitOverlay): modified to emit a commented overlay segment
4633 directive when no overlay data exist
4634 * (picglue): modified to emit uninitialized data segment
4635 according to udata_section_name

4645 2004-01-07 Borut Razem <borut.razem AT siol.net>
4647 * support/scripts/sdcc.nsi: update PATH
4648 * support/scripts/sdcc.ico: craeted

4655 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4657 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4659 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4661 include information about variables allocated to the overlay
4664 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4666 * as/mcs51/lkmain.c: Help about -Y option

4678 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4680 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4681 (default behaviour).
4683 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4685 A python script to validate compiler diagnostic messages. It can be
4686 used to verify that sdcc complains about bad c source code and
4687 gives a good location of the error.
4688 * support/valdiag/Makefile,
4689 * support/valdiag/valdiag.py,
4690 * support/valdiag/tests/*
4692 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4694 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4705 * src/common.h: added ifndef/define/endif macros
4706 around the header file.
4707 Bug reported from Jesus Calvino-Fraga
4709 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4711 * sdcc.spec: updated
4712 * device/include/Makefile.in: don't install CVS directories
4713 * device/lib/Makefile.in: added removal of CVS directories after install
4714 * doc/Makefile: fixed install, added local_icons
4715 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4716 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4717 * src/ds390/gen.c (genRightShift): fixed bug #870788
4718 * src/SDCCast.c (decorateType): fixed bug #870781
4720 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4722 PIC16 port related changes:
4723 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4724 added variable stackPos,
4726 * gen.c: genCall, assignResultValue: added support for
4727 pushing/retrieving function parameters to/from stack,
4728 genFunction,genEndFunction: setup stack frame for the
4730 genAddrOf: will be changed according to bug 863624
4732 * added files genutils.c and genutils.h which contain gen*
4733 debugged and optimised functions extracted from gen.c
4735 * glue.c: added variable 'externs' which holds extern symbols,
4736 pic16emitRegularMap: is modified to properly handle relocatable
4737 symbols under the new scheme,
4738 pic16createInterruptVect: is modified
4739 pic16printPublics: is modified to emit 'global' assembler directives,
4740 added pic16_printExterns to print extern symbols,
4741 pic16glue: initializes stack/frame pointer in the beginning of
4742 the assembly output. Temporary hack, will be corrected later,
4743 because gplink yet does not support stack and SDCC does not
4744 yet support a type of crt0.o object to create the final binary.
4746 * Removed many lines that contain 8051 legacy code.
4747 * The code is finally placed under a 'code' directive.
4748 * Added port specific options.
4750 * _process_pragma: simplified since now we do not need *special*
4751 include file to define SFR registers. But a separate header
4752 will be needed. This will be developed later.
4753 * _pic16_parseOptions: added, parses port specific options:
4754 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4755 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4756 --preplace-udata-with=
4758 * _pic16_setDefaultOptions: modified to initialize section names,
4759 but hack is temporarly out of order since it needs improvement.
4760 * _pic16_genAssemblerPreamble: configuration words are emitted by
4761 their address instead of their name. This part is incomplete and
4762 supports only the 18Fxx2 devices. Other devices will emit an error
4763 during assembly since they do not contain the same set of config
4765 * _pic16_genIVT: is modified,
4767 * pcode.c: added definitions for some hardware registers that are needed
4769 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4770 All PCI entries are updated. Now LFSR is supported.
4771 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4772 * added pic16_newpCodeOpLit2 to support instructions with
4773 two literal arguments
4774 * pic16_pCode2str: corrected code that emits assembler instructions
4775 with two literal operands and those that have an access bit modifier
4776 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4777 this fixes a bug which caused some labels to be lost, when an
4778 assembler directive was added, i.e. banksel,
4779 * pic16_FixRegisterBanking: improved logic that causes the insertion
4781 * InlineFunction: functions that are called once, are not any more
4782 inlined. This can be a port option in the future,
4784 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4786 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4787 hold the corresponding uninitialized symbols,
4788 * pic16_allocProcessorRegister: registers have explicit marked the
4790 * pic16_allocInternalRegister: registers are explicit marked as
4792 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4793 processing list, so bit registers were lost,
4796 * ralloc.h: added field 'accessBank' and original symbol operand
4797 in register definition,
4798 * removed the field isMapped from register definition,
4800 ** Several functions have been removed from various sources:
4801 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4802 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4803 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4804 pic16_assignRelocatableRegisters
4806 ** others have been introduced:
4807 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4808 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4810 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4812 * support/scripts/inc2h.pl: changed definition of BIT_AT
4813 to emit 'sbit at' instead of 'bit at'. This was a request.
4815 PIC16 port related preliminary changes:
4816 * gen.c: prefixed function popRegFromString with
4817 pic16_ and all references to it corrected
4818 * pcode.c: all pic16_pc_* hardware registers prefixed
4819 with underscore (_),
4820 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4821 * ralloc.c: newReg(): when register is REG_SFR then
4822 set address to rIdx,
4823 pic16_allocProcessorRegister(): marks register wasUsed=0
4824 pic16_writeUsedRegs(): added a call to assign processor
4825 registers via pic16_assignFixedRegisters
4827 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4829 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4830 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4831 variables in unused register banks. Also the SSEG is placed
4832 wherever there is enough space for it, and IDATA can be anywhere
4833 in internal RAM. For now compile using -Wl-Y[stack_size].
4834 The mem file is different for this option as well, since it
4835 makes no sense of talking about DSEG lenght.
4837 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4839 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4840 in certain cases, e.g. when ROM assignment, patch provided
4841 from Albert den Haan.
4843 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5866 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5867 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5868 type for bits was changed. It resulted in bit variables becoming

5886 A few small changes that speed up the peephole optimizer.
5890 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5892 Try to make the peephole optimizer smarter by maintaining
5893 an association between the assembly source code and the
5894 iCodes that originated them. Put this information to use
5895 with a new peephole rule condition "notVolatile" so that
5896 the rules can be aggressive yet still safe.
5901 * src/mcs51/peeph.def
5903 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5907 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5908 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5909 if the left or right operand symbols have the accuse flag set.
5911 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5913 Changed the type of the result of the ! (NOT) operator to char;
5914 previously it returned the same type as the source. This allows
5915 us to eliminate all the genFloatNot functions (all of its target
5916 implementations were very buggy) since !float can use the same

5928 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5929 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5930 during interrupts. Ensure WSAVE is located at a shared bank address.
5931 2. Fixed page selection in some places
5932 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5933 the registers name strings.
5934 4. Fixed "signed / unsigned compare" compiler warnings.
5935 5. The PIC port manages its own allocation of the general purpose
5936 registers, but makes no attempt to reuse them. As a result when
5937 compiling it soon runs out of general purpose registers. Some
5938 additional code was added to the files pcode.c and device.c to walk

6025 omitted, the function will not automatically be given an entry
6026 in the interrupt vector table (similar to #pragma NOIV, but
6027 less syntacticly kludgy). The interrupt number is also now
6028 range checked. Also fixed a bug in the high order bit example

6531 * src/pic16/pcode.c: Cleaned warnings
6532 * src/pic16/pcodeflow.c: Cleaned warnings
6533 * src/pic16/pcoderegs.c: Cleaned warnings
6535 2003-05-19 Scott Dattalo <scott AT dattalo.com>
6537 * src/pic16/pcode.c: Cleaned warnings
6538 * src/pic16/pcodepeep.c: Cleaned warnings

6543 * doc/sdccman.lyx: fixed bug 739745
6544 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
6546 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6548 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6549 it can be defined with CFLAGS when running configure
6550 * src/SDCCmain.c: fixed compiling + linking with object files
6552 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6554 * configure.in: configure for pic16 port,
6555 added --disable-pic16-port
6556 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6557 * src/SDCCmain.c: linkOptions is changed to set *,
6558 added if/endif conditional macros to remove options help
6559 messages from optionsTable when a port is not configured, added
6560 support for the PIc16 port in the ports table, when executing
6561 the compiler with no port specified on command line, a default
6562 port is selected with the new macro DEFAULT_PORT which is
6563 defined in port.h, in setDefaultOptions() linkOptions is removed
6564 from initialization assignment, since now it is a set,
6565 parseCmdLine uses setParseWithComma for linkOptions, in
6566 linkEdit() linkOptions are accessed with new function indexSet()
6567 which returns the i'th item of a set variable. See SDCCset.c, in
6568 linkEdit() when calling buildCmdLine(), added linkOptions as
6569 last argument. Now users can pass arguments to gplink via the
6570 -Wl option, main() uses pic16glue() to glue up pic16 programs
6571 * src/SDCCpeeph.c: various changes to support pic16
6572 * src/SDCCset.c: added function void *indexSet(set *, int) to
6573 return the i'th item of the set

6578 added macro DEFAULT_PORT
6579 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
6580 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6582 * src/pic16/glue.c: commented out some error producing lines
6583 * src/pic16/main.c: __config directives are commented out to stop
6584 gpasm complaining and test the linkage with gplink, _linkCmd and
6585 _asmCmd changed to be more gplink and gpasm friendly
6586 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6587 produced an error when parsed, peep rule 12 is added to utilize
6588 movff, but it is commented out since the pCode does not support
6589 yet a command with 2 address arguments
6591 2003-05-18 <johan AT balder>
6593 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6594 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6618 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6620 2003-05-11 Borut Razem <borut.razem AT siol.net>
6622 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6623 the path of bin directory, so that PATH is the only env. variable, which has to be set
6624 in case of standard installation.

7628 * src/SDCCicode.c: fixed array add
7630 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7631 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7632 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7634 2003-01-04 <johan AT balder>
7636 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7638 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7639 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7641 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7651 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7652 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7654 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7656 * in \sdcc\as\mcs51\ changed these files in order to create an
7657 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7658 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7659 following files to include the previous two files: aslink.dsp,
7660 Makefile.aslink, Makefile.bcc, and Makefile.in.
7662 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7663 .adb instead of .cdb
7665 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7667 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7668 value from option --iram-size.
7670 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7672 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7675 2002-09-18 <wiml AT hhhh.org>
7677 * SDCClrange.h: exposed setFromRange() and setToRange()
7678 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7679 packRegsForAccUse() (bug 542397)
7680 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7681 multiple times and emitting the fetch operations more than once
7682 added aopGetUsesAcc() function to allow binary operators to
7683 fetch their operands in the correct order; made genMinus() emit
7684 compact code for X = LITERAL - Y
7686 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7687 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7688 sprintf() in line 1267.
7690 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7691 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7694 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7695 Changes to aslink (All the changes are marked with 'JCF'):
7697 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7700 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7701 area BSEG. Also moves, if possible, the DATA area down into the internal
7702 ram so more space is available.
7704 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7707 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7708 not bytes. Function summary() which creates a memory usage summary
7709 file with extension .mem. Reports of overlaping stack and small stack
7710 size. If the space for the stack is less than 16 bytes aslink trows a
7713 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7714 the 8051. Option 'y' for memory summary output file.
7716 Changes to sdcc (All the changes are marked with 'JCF'):
7718 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7720 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7721 overlaying area for it (uses RegBankUsed[4]).
7723 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7724 bank zero as used by default. By default aslink locates the stack
7725 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7726 the creation of the .mem file. Delegates the allocation of data area
7727 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7728 the begining of the stack area to aslink.
7730 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7731 glue() in SDCCglue.c creates an area for it.
7733 2002-09-03 Borut Razem <borut.razem AT siol.net>
7734 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7735 sdcc/src/pic/glue.c:
7736 introduced atexit() handler for teporay files removal in case of
7737 errors, assertions, ...
7739 2002-08-29 Borut Razem <borut.razem AT siol.net>
7740 * sdcc/support/cpp2/auto-host_vc_in.h:
7741 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7742 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7743 Maybe there is a similar problem with BORLANDC? It should be checked!
7745 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7746 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7747 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7748 was not executed, and the compiler (cl) launched a warning:
7749 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7751 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7752 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7754 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7755 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7757 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7758 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7759 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7760 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7761 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7762 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7763 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7764 - added Release configuration in VS projects
7765 - review of compiler an linker options
7766 - VC .exe files are generated in bin_vc directory, not to interfere
7767 with binaries generated from other projects (cygwin, mingw, bcc ...)
7769 * sdcc/src/yacc.dsp: added
7771 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7772 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7773 and insert the version number definitions from .version
7775 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7777 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7778 added - genarate auto-host.h using auto-host_vc_in.h as template
7781 removed from CVS, generated automatically
7783 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7784 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7786 2002-08-11 Borut Razem <borut.razem AT siol.net>
7787 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7789 2002-08-10 Borut Razem <borut.razem AT siol.net>
7790 * src/SDCCmain.c (main):
7791 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7792 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7793 The consequence was that some temporary files were not removed.
7796 unification of code in functions tempfilename() and tempfile():
7797 function tempnam() is defined in Visual Studio 6.0 and .NET
7799 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7801 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7802 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7803 - removed compiler command line option /WX: Treats all warnings as errors
7804 - update a list of source files, included into the project
7806 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7807 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7808 changed project type to Generic Project so that can be correcly converted to VS.NET project
7810 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7812 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7814 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7816 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7817 added return 0 statements after assert() to make compiler happy
7819 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7820 added newline in the def file to keep MSC compiler satisfied
7822 * sdcc/src/z80/gen.c:
7823 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7824 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7825 - solved MSC error in function aopDump()
7827 * sdcc_vc.h: define PREFIX as "\\sdcc"
7829 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7830 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7832 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7833 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7834 - Rewrote the register banking algorithm.
