447 where not placed in the same memory bank,
448 * device/lib/pic16/libsdcc/char/: various modifications to improve
450 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
451 information on the new functions of the c library and more...
453 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

460 if condition == CARRY)
461 * (genCmp): adapted to new genSkipc semantics
462 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
463 on rIfx (genCmp was broken)
465 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
467 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
468 * src/z80/main.c (_keywords[]),
469 * src/SDCCglobal.h (struct options),
471 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
472 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
473 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
474 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
475 always available in leading double underscore form. The C99 support is
476 mostly missing, but it's a start.
477 * support/regression/tests/bug-227710.c: fixed nonconforming use of
478 reserved identifier "__data".
480 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

526 2005-03-20 Borut Razem <borut.razem AT siol.net>
528 * support/scripts/inc2h.pl: WIN32 port

554 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
556 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
558 * device/lib/printf_large.c: removed inline assembly for portability and
559 readability. Use printf_fast if speed or size are more important.
560 * src/pic16/gen.c: removed conditions around use of DEBUGpc
561 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
563 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
565 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
566 prevent compiler warning
568 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
570 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
571 moved to level 0 and declared as static. Also they are explicit
572 placed in access bank. This was necessery because some times they
573 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
574 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
575 optimizations. Currently only compare to unsigned char is implemented,
576 * src/pic16/gen.c: added fReturnIdx array,
577 * (struct resolvedIfx) is moved to gen.h and made public,
578 * (struct _G): added sregsAlloc and sregsAllocSet fields,
579 * (aopForSym): added an optimization to directly store in stack of
580 the operand of a SEND iCode,
581 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
582 but as registers instead (AOP_REG) using the fReturnIdx array,
583 * (pic16_freeAsmop): remove the freed register from the
585 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
587 * (pic16_popGetTempRegCond): changed function prototype, now
588 function takes also a bitVector argument v which holds the current
589 set of registers that are allocated for stack access by aopForSym,
590 registers allocated in aopForSym for accessing stack symbols are not
591 any more part of the functions usedRegs field,
592 * (genCall): some times aopOp is called for a stack variable to be
593 send, aopForSym might perform the push, if this is true make sure
594 that genCall doesn't push the variable twice by testing _G.resDirect,
595 * (genFunction): changed testing for unspecified interrupt number
596 from 256 to INTNO_UNSPEC,
597 * modified selection scheme of frame pointer generation. Previously
598 if function did use local registers a frame pointer was generated,
599 now a frame pointer is generated only if function has arguments
600 (that need PLUSW2 register access), or has stack arguments, or the
601 compiler is not instructed to omit the frame pointer,
602 * (genEndFunction): before restoring local registers that were saved
603 in the function preamble, also restore the registers that *might*
604 have been allocated for stack access,
605 * (genRet): removed some old comments,
606 * (genCmp, the active (RN's) version): added a call to the
607 pic16_genCmp_special function to perform the compare with a more
608 robust and optimized way,
609 * (genInline): a feature has been added in inline code generation,
610 which allows a wildcard variable substitution when writing inline
611 assembly. Code is incomplete and experimental therefore undocumented,
612 * (genCast): changed order of aopOp for result and right to allow
613 aopForSym to directly load the result if possible,
614 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
615 perform an optimized compare on some selected special occasions,
616 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
617 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
618 generate an IVT any more,
619 * src/pic16/main.c (pic16_optionsTable): added command line option
621 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
622 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
624 * src/pic16/NOTES: Raphael Neider added in list of active developers
625 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
626 jumptable_end to prevent bug #,
627 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
628 inCond and outCond fields,
629 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
630 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
631 turn off register spilling,
632 * (packRegsForOneUse): synced with other ports' versions although it
633 is not used currently,
634 * (pic16_packRegisters): added an optimization while reading
635 structure bitfields, some registers may be saved (malloc code is
636 decreased by 80 bytes)
638 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
640 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
641 left is a bitfield, if yes, then don't optimize assignment. Perhaps
642 this can be optimized more?
644 2005-03-10 Raphael Neider <rneider AT web.de>
646 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
647 genNearPointerGet): (hopefully) fixed access to bitfields via
648 pointers (p->bitN = x; and x = p->bitN; failed)

1282 Adding support for replacing ljmps with sjmps in jumptables
1283 generated for switch statements. For now you need to set the
1284 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1285 Now 4 algorithms for mcs51 jumptable generation are used:
1286 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1287 addresses loaded pc-relative for up to 112 cases and stack-pushing
1288 target addresses loaded with offset from dptr for up to 256 cases.

1314 Large cummulative patch for pic16 port.
1315 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1316 to call when a stack overflow occurs,
1317 * (malloc.h): added CVS Id tag,
1318 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1320 * added libc directory. The current version of LibC contains string
1321 functions, ctype functions and macros and some functions of the
1322 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1323 be extensively tested in the future. Standard disclaimer here.
1324 Library is not automatically build yet. But one can build it by
1325 invoking 'make' inside the libc directory.
1326 * added ADC library under libio. Preliminary version yet.
1328 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1329 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1330 aopForRemat() now and not by pic16_aopOp(),
1331 * (pic16_popGetTempReg): removed warning messgae when allocating
1332 temporary registers, its a buggy feature and will be removed,
1333 * (pic16_popGet): set register instance field in AOP_CRY,
1334 * (pic16_outBitC): fixed for results in size greater than 1,
1335 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1336 * (pic16_storeForReturn): optimized return of 0,
1337 * (genCmp): experimental code for new genCmp which uses PIC18's
1338 special compare&skip instructions. Initial tests fail some times
1339 with variables grater than 1 byte in size, so new code is disabled,
1340 * (genUnpackBits, genPackBits): more optimizations in reading/writing,

4366 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4368 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4369 loaded with the linker search paths (-L arguments) and the libraries
4370 to be linked with the current source (-l arguments). Changes
4371 currently will affect only the pic16 port.
4372 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4373 include path the port specific paths and port specific libraries,
4374 * gplink command now contains the $3 argument,
4375 * src/pic16/device.h,
4376 * src/pic16/device.c,: structure PIC_device is made public and
4377 renamed to PIC16_device, the same for variable Pics which is renamed

4392 Documenting changes from previous commits.
4393 * configure.in (version 1.56),
4394 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4395 when generating output files to configure the pic16 library,
4396 but now I've commented it out, since gputils aren't installed in the
4397 SF compile farm, so library won't compile
4399 * device/lib/Makefile.in (version 1.56): initially I've added in
4400 target 'all' the prerequestive 'model-pic16' so it compiled the
4401 pic16 library, but now I've commented it out for the same reasons
4403 * added targets 'model-pic16' and 'objects-pic16' to compile the
4405 * added target 'port-specific-objects-pic16' to handle the
4406 generated libraries and copy them into the build/ directory
4407 * added target 'clean-intermediate-pic16' to clean intermediate
4408 files into pic16 directory
4409 * in target 'installdirs' added line to create directory pic16 in
4410 the installation path
4412 * device/include/Makefile.in (version 1.11): in target 'install'
4413 added lines to copy all header files to installation path,
4414 * in target 'installdirs' added line create directory for pic16
4415 headers in the installation path

4430 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4431 option so that it actually works. Made it specific to the z80, since
4432 the gbz80 doesn't have these kinds of I/O ports.
4434 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4436 * device/include/z180.h,

4460 via literal number. The symbol is placed in the corresponding
4461 position of the data ram
4462 * (pic16_dump_section): relocatable and absolute uninitialized
4463 data are now emitted in sorted order to reduce section naming,
4464 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4465 weren't marked as being in the access bank,
4467 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4469 Added portion of GNU PIC Library under the directory
4470 device/include/pic16 and device/lib/pic16. These files
4471 contain the declarations of SFRs for the PIC18Fxx2 devices.
4472 The directory is initialized via configure from toplevel.
4474 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4501 * doc/sdccman.lyx: Moved and added some sections, small changes
4502 all over. Telling LaTeX to be less strict with word spacing
4503 to better keep the right margin. Changed some notes about
4504 maintainance of the ports in section 3.2.1 - is it OK like this?
4506 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4543 UPPER for immediate operands,
4544 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4546 * src/pic16/peeph.def: all peepholes with movff are commented out,
4547 because there is a problem in the pcode peep optimizer,
4548 * src/pic16/ralloc.c: the register allocator can now reuse local

4585 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4588 * src/z80/main.c: added missed needLinkerScript flags (more than
4589 one port structure defined in these file)
4590 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4612 * (pic14emitOverlay): modified to emit a commented overlay segment
4613 directive when no overlay data exist
4614 * (picglue): modified to emit uninitialized data segment
4615 according to udata_section_name

4620 arguments via -W option
4621 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4622 object file from '.rel' to '.o' in port->linker structure,

4625 2004-01-07 Borut Razem <borut.razem AT siol.net>
4627 * support/scripts/sdcc.nsi: update PATH
4628 * support/scripts/sdcc.ico: craeted

4641 include information about variables allocated to the overlay
4644 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4646 * as/mcs51/lkmain.c: Help about -Y option

4658 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4660 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4661 (default behaviour).
4663 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4665 A python script to validate compiler diagnostic messages. It can be
4666 used to verify that sdcc complains about bad c source code and
4667 gives a good location of the error.
4668 * support/valdiag/Makefile,
4669 * support/valdiag/valdiag.py,
4670 * support/valdiag/tests/*
4672 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4674 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4686 around the header file.
4687 Bug reported from Jesus Calvino-Fraga
4689 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4691 * sdcc.spec: updated
4692 * device/include/Makefile.in: don't install CVS directories
4693 * device/lib/Makefile.in: added removal of CVS directories after install
4694 * doc/Makefile: fixed install, added local_icons
4695 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4696 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4697 * src/ds390/gen.c (genRightShift): fixed bug #870788
4698 * src/SDCCast.c (decorateType): fixed bug #870781
4700 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4702 PIC16 port related changes:
4703 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4704 added variable stackPos,
4706 * gen.c: genCall, assignResultValue: added support for
4707 pushing/retrieving function parameters to/from stack,
4708 genFunction,genEndFunction: setup stack frame for the
4710 genAddrOf: will be changed according to bug 863624
4712 * added files genutils.c and genutils.h which contain gen*
4713 debugged and optimised functions extracted from gen.c
4715 * glue.c: added variable 'externs' which holds extern symbols,
4716 pic16emitRegularMap: is modified to properly handle relocatable
4717 symbols under the new scheme,
4718 pic16createInterruptVect: is modified
4719 pic16printPublics: is modified to emit 'global' assembler directives,
4720 added pic16_printExterns to print extern symbols,
4721 pic16glue: initializes stack/frame pointer in the beginning of
4722 the assembly output. Temporary hack, will be corrected later,
4723 because gplink yet does not support stack and SDCC does not
4724 yet support a type of crt0.o object to create the final binary.
4726 * Removed many lines that contain 8051 legacy code.
4727 * The code is finally placed under a 'code' directive.
4728 * Added port specific options.
4730 * _process_pragma: simplified since now we do not need *special*
4731 include file to define SFR registers. But a separate header
4732 will be needed. This will be developed later.
4733 * _pic16_parseOptions: added, parses port specific options:
4734 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4735 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4736 --preplace-udata-with=
4738 * _pic16_setDefaultOptions: modified to initialize section names,
4739 but hack is temporarly out of order since it needs improvement.
4740 * _pic16_genAssemblerPreamble: configuration words are emitted by
4741 their address instead of their name. This part is incomplete and
4742 supports only the 18Fxx2 devices. Other devices will emit an error
4743 during assembly since they do not contain the same set of config
4745 * _pic16_genIVT: is modified,
4747 * pcode.c: added definitions for some hardware registers that are needed
4749 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4750 All PCI entries are updated. Now LFSR is supported.
4751 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4752 * added pic16_newpCodeOpLit2 to support instructions with
4753 two literal arguments
4754 * pic16_pCode2str: corrected code that emits assembler instructions
4755 with two literal operands and those that have an access bit modifier
4756 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4757 this fixes a bug which caused some labels to be lost, when an
4758 assembler directive was added, i.e. banksel,
4759 * pic16_FixRegisterBanking: improved logic that causes the insertion
4761 * InlineFunction: functions that are called once, are not any more
4762 inlined. This can be a port option in the future,
4764 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4766 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4767 hold the corresponding uninitialized symbols,
4768 * pic16_allocProcessorRegister: registers have explicit marked the
4770 * pic16_allocInternalRegister: registers are explicit marked as
4772 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4773 processing list, so bit registers were lost,
4776 * ralloc.h: added field 'accessBank' and original symbol operand
4777 in register definition,
4778 * removed the field isMapped from register definition,
4780 ** Several functions have been removed from various sources:
4781 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4782 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4783 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4784 pic16_assignRelocatableRegisters
4786 ** others have been introduced:
4787 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4788 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4790 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4792 * support/scripts/inc2h.pl: changed definition of BIT_AT
4793 to emit 'sbit at' instead of 'bit at'. This was a request.
4795 PIC16 port related preliminary changes:
4796 * gen.c: prefixed function popRegFromString with
4797 pic16_ and all references to it corrected
4798 * pcode.c: all pic16_pc_* hardware registers prefixed
4799 with underscore (_),
4800 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4801 * ralloc.c: newReg(): when register is REG_SFR then
4802 set address to rIdx,
4803 pic16_allocProcessorRegister(): marks register wasUsed=0
4804 pic16_writeUsedRegs(): added a call to assign processor
4805 registers via pic16_assignFixedRegisters
4807 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4809 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4810 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4811 variables in unused register banks. Also the SSEG is placed
4812 wherever there is enough space for it, and IDATA can be anywhere
4813 in internal RAM. For now compile using -Wl-Y[stack_size].
4814 The mem file is different for this option as well, since it
4815 makes no sense of talking about DSEG lenght.
4817 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4819 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4820 in certain cases, e.g. when ROM assignment, patch provided
4821 from Albert den Haan.
4823 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4966 * src/mcs51/peephole.def,
4967 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4968 (allows non-interrupt and interrupt code to safely compete for a resource
4969 without the non-interrupt code having to disable interrupts)

4993 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4995 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

5846 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5847 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

5866 A few small changes that speed up the peephole optimizer.
5870 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5872 Try to make the peephole optimizer smarter by maintaining
5873 an association between the assembly source code and the
5874 iCodes that originated them. Put this information to use
5875 with a new peephole rule condition "notVolatile" so that
5876 the rules can be aggressive yet still safe.
5881 * src/mcs51/peeph.def
5883 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5887 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5888 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5889 if the left or right operand symbols have the accuse flag set.
5891 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5893 Changed the type of the result of the ! (NOT) operator to char;
5894 previously it returned the same type as the source. This allows
5895 us to eliminate all the genFloatNot functions (all of its target
5896 implementations were very buggy) since !float can use the same

5908 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5909 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5910 during interrupts. Ensure WSAVE is located at a shared bank address.
5911 2. Fixed page selection in some places
5912 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5913 the registers name strings.
5914 4. Fixed "signed / unsigned compare" compiler warnings.
5915 5. The PIC port manages its own allocation of the general purpose
5916 registers, but makes no attempt to reuse them. As a result when
5917 compiling it soon runs out of general purpose registers. Some
5918 additional code was added to the files pcode.c and device.c to walk
5919 through the function call tree and rename the registers so that they
5929 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5936 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5938 Made bitfield a distinct type from bit so that bitfields
5939 convert as per ANSI C and bits retain their traditional
5940 boolean style behaviour. Implemented bitfield support in
5948 * src/ds390/gen.c: bit v bitfield split
5949 * src/z80/gen.c: New support for bitfields
5950 * support/regression/tests/bitfields.c: reenabled z80,
5953 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5963 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5964 for literal assignments in genPackBits (thanks to Frieder for
5970 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5972 Fixed bug #748310 (pointer to function type mishandled when the

6004 Made the constant following the "interrupt" keyword optional. If
6005 omitted, the function will not automatically be given an entry
6006 in the interrupt vector table (similar to #pragma NOIV, but
6007 less syntacticly kludgy). The interrupt number is also now
6008 range checked. Also fixed a bug in the high order bit example

6029 unsigned, but are signed by default
6030 * src/SDCCval.c (constVal): rearranged
6031 * src/SDCCval.c (valMod): preliminary fix
6032 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6530 * src/SDCCmain.c: fixed compiling + linking with object files
6532 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6534 * configure.in: configure for pic16 port,
6535 added --disable-pic16-port
6536 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6537 * src/SDCCmain.c: linkOptions is changed to set *,
6538 added if/endif conditional macros to remove options help
6539 messages from optionsTable when a port is not configured, added
6540 support for the PIc16 port in the ports table, when executing
6541 the compiler with no port specified on command line, a default
6542 port is selected with the new macro DEFAULT_PORT which is
6543 defined in port.h, in setDefaultOptions() linkOptions is removed
6544 from initialization assignment, since now it is a set,
6545 parseCmdLine uses setParseWithComma for linkOptions, in
6546 linkEdit() linkOptions are accessed with new function indexSet()
6547 which returns the i'th item of a set variable. See SDCCset.c, in
6548 linkEdit() when calling buildCmdLine(), added linkOptions as
6549 last argument. Now users can pass arguments to gplink via the
6550 -Wl option, main() uses pic16glue() to glue up pic16 programs
6551 * src/SDCCpeeph.c: various changes to support pic16
6552 * src/SDCCset.c: added function void *indexSet(set *, int) to

6562 * src/pic16/glue.c: commented out some error producing lines
6563 * src/pic16/main.c: __config directives are commented out to stop
6564 gpasm complaining and test the linkage with gplink, _linkCmd and
6565 _asmCmd changed to be more gplink and gpasm friendly
6566 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6567 produced an error when parsed, peep rule 12 is added to utilize
6568 movff, but it is commented out since the pCode does not support
6569 yet a command with 2 address arguments
6571 2003-05-18 <johan AT balder>

6600 2003-05-11 Borut Razem <borut.razem AT siol.net>
6602 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7608 * src/SDCCicode.c: fixed array add
7610 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7611 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7612 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7614 2003-01-04 <johan AT balder>
7616 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7618 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7619 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7621 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7622 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7631 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7632 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7634 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7636 * in \sdcc\as\mcs51\ changed these files in order to create an
7637 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7638 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7639 following files to include the previous two files: aslink.dsp,
7640 Makefile.aslink, Makefile.bcc, and Makefile.in.
7642 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7643 .adb instead of .cdb
7645 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7647 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7648 value from option --iram-size.
7650 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7652 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7655 2002-09-18 <wiml AT hhhh.org>
7657 * SDCClrange.h: exposed setFromRange() and setToRange()
7658 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7659 packRegsForAccUse() (bug 542397)
7660 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7661 multiple times and emitting the fetch operations more than once
7662 added aopGetUsesAcc() function to allow binary operators to
7663 fetch their operands in the correct order; made genMinus() emit
7664 compact code for X = LITERAL - Y
7666 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7667 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7668 sprintf() in line 1267.
7670 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7671 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7674 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7675 Changes to aslink (All the changes are marked with 'JCF'):
7677 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7680 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7681 area BSEG. Also moves, if possible, the DATA area down into the internal
7682 ram so more space is available.
7684 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7687 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7688 not bytes. Function summary() which creates a memory usage summary
7689 file with extension .mem. Reports of overlaping stack and small stack
7690 size. If the space for the stack is less than 16 bytes aslink trows a
7693 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7694 the 8051. Option 'y' for memory summary output file.
7696 Changes to sdcc (All the changes are marked with 'JCF'):
7698 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7700 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7701 overlaying area for it (uses RegBankUsed[4]).
7703 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7704 bank zero as used by default. By default aslink locates the stack
7705 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7706 the creation of the .mem file. Delegates the allocation of data area
7707 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7708 the begining of the stack area to aslink.
7710 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7711 glue() in SDCCglue.c creates an area for it.
7713 2002-09-03 Borut Razem <borut.razem AT siol.net>
7714 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7715 sdcc/src/pic/glue.c:
7716 introduced atexit() handler for teporay files removal in case of
7717 errors, assertions, ...
7719 2002-08-29 Borut Razem <borut.razem AT siol.net>
7720 * sdcc/support/cpp2/auto-host_vc_in.h:
7721 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7722 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7723 Maybe there is a similar problem with BORLANDC? It should be checked!
7725 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7726 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7727 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7728 was not executed, and the compiler (cl) launched a warning:
7729 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7731 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7732 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7734 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7735 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7737 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7738 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7739 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7740 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7741 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7742 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7743 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7744 - added Release configuration in VS projects
7745 - review of compiler an linker options
7746 - VC .exe files are generated in bin_vc directory, not to interfere
7747 with binaries generated from other projects (cygwin, mingw, bcc ...)
7749 * sdcc/src/yacc.dsp: added
7751 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7752 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7753 and insert the version number definitions from .version
7755 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7757 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7758 added - genarate auto-host.h using auto-host_vc_in.h as template
7761 removed from CVS, generated automatically
7763 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7764 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7766 2002-08-11 Borut Razem <borut.razem AT siol.net>
7767 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7769 2002-08-10 Borut Razem <borut.razem AT siol.net>
7770 * src/SDCCmain.c (main):
7771 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7772 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7773 The consequence was that some temporary files were not removed.
7776 unification of code in functions tempfilename() and tempfile():
7777 function tempnam() is defined in Visual Studio 6.0 and .NET
7779 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7781 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7782 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7783 - removed compiler command line option /WX: Treats all warnings as errors
7784 - update a list of source files, included into the project
7786 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7787 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7788 changed project type to Generic Project so that can be correcly converted to VS.NET project
7790 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7792 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7794 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7796 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7797 added return 0 statements after assert() to make compiler happy
7799 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7800 added newline in the def file to keep MSC compiler satisfied
7802 * sdcc/src/z80/gen.c:
7803 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7804 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7805 - solved MSC error in function aopDump()
7807 * sdcc_vc.h: define PREFIX as "\\sdcc"
7809 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7810 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7812 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7813 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7814 - Rewrote the register banking algorithm.
7815 - Added pCode live-range analysis to registers (for now, only non-used and
7816 singly-used registers optimized away)
7818 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7820 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
7822 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7823 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7825 2002-04-22 Michael Hope <michaelh AT vroom>
7827 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
7829 * configure.in (DD_COPT): Added include support required for gbdk.
