444 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
445 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
446 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
447 always available in leading double underscore form. The C99 support is
448 mostly missing, but it's a start.
449 * support/regression/tests/bug-227710.c: fixed nonconforming use of
450 reserved identifier "__data".
452 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

496 immedDom() returning wrong block; probably fixes bug #1160833)
498 2005-03-20 Borut Razem <borut.razem AT siol.net>
500 * support/scripts/inc2h.pl: WIN32 port

518 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
520 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
523 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
525 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
526 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
528 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
530 * device/lib/printf_large.c: removed inline assembly for portability and
531 readability. Use printf_fast if speed or size are more important.
532 * src/pic16/gen.c: removed conditions around use of DEBUGpc
533 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
535 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
537 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
538 prevent compiler warning
540 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
542 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
543 moved to level 0 and declared as static. Also they are explicit
544 placed in access bank. This was necessery because some times they
545 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
546 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
547 optimizations. Currently only compare to unsigned char is implemented,
548 * src/pic16/gen.c: added fReturnIdx array,
549 * (struct resolvedIfx) is moved to gen.h and made public,
550 * (struct _G): added sregsAlloc and sregsAllocSet fields,
551 * (aopForSym): added an optimization to directly store in stack of
552 the operand of a SEND iCode,
553 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
554 but as registers instead (AOP_REG) using the fReturnIdx array,
555 * (pic16_freeAsmop): remove the freed register from the
557 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
559 * (pic16_popGetTempRegCond): changed function prototype, now
560 function takes also a bitVector argument v which holds the current
561 set of registers that are allocated for stack access by aopForSym,
562 registers allocated in aopForSym for accessing stack symbols are not
563 any more part of the functions usedRegs field,
564 * (genCall): some times aopOp is called for a stack variable to be
565 send, aopForSym might perform the push, if this is true make sure
566 that genCall doesn't push the variable twice by testing _G.resDirect,
567 * (genFunction): changed testing for unspecified interrupt number
568 from 256 to INTNO_UNSPEC,
569 * modified selection scheme of frame pointer generation. Previously
570 if function did use local registers a frame pointer was generated,
571 now a frame pointer is generated only if function has arguments
572 (that need PLUSW2 register access), or has stack arguments, or the
573 compiler is not instructed to omit the frame pointer,
574 * (genEndFunction): before restoring local registers that were saved
575 in the function preamble, also restore the registers that *might*
576 have been allocated for stack access,
577 * (genRet): removed some old comments,
578 * (genCmp, the active (RN's) version): added a call to the
579 pic16_genCmp_special function to perform the compare with a more
580 robust and optimized way,
581 * (genInline): a feature has been added in inline code generation,
582 which allows a wildcard variable substitution when writing inline
583 assembly. Code is incomplete and experimental therefore undocumented,
584 * (genCast): changed order of aopOp for result and right to allow
585 aopForSym to directly load the result if possible,
586 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
587 perform an optimized compare on some selected special occasions,
588 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
589 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
590 generate an IVT any more,
591 * src/pic16/main.c (pic16_optionsTable): added command line option
593 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
594 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
596 * src/pic16/NOTES: Raphael Neider added in list of active developers
597 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
598 jumptable_end to prevent bug #,
599 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
600 inCond and outCond fields,
601 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
602 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
603 turn off register spilling,
604 * (packRegsForOneUse): synced with other ports' versions although it
605 is not used currently,
606 * (pic16_packRegisters): added an optimization while reading
607 structure bitfields, some registers may be saved (malloc code is
608 decreased by 80 bytes)
610 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
612 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
613 left is a bitfield, if yes, then don't optimize assignment. Perhaps
614 this can be optimized more?
616 2005-03-10 Raphael Neider <rneider AT web.de>
618 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
619 genNearPointerGet): (hopefully) fixed access to bitfields via
620 pointers (p->bitN = x; and x = p->bitN; failed)

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

905 operands (genAddLit expects the iCode's operands to swapped as
906 well), fixed leftover bytes (crashed for short left operands)

1255 generated for switch statements. For now you need to set the
1256 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1257 Now 4 algorithms for mcs51 jumptable generation are used:
1258 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1292 * added libc directory. The current version of LibC contains string
1293 functions, ctype functions and macros and some functions of the
1294 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1295 be extensively tested in the future. Standard disclaimer here.
1296 Library is not automatically build yet. But one can build it by

1308 * (pic16_storeForReturn): optimized return of 0,
1309 * (genCmp): experimental code for new genCmp which uses PIC18's
1310 special compare&skip instructions. Initial tests fail some times
1311 with variables grater than 1 byte in size, so new code is disabled,
1312 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1314 * (genCast): began a fix to optimize the casting of a bit to another
1315 bit, now assigning a bitfield to another bitfield will fail, sorry,

1324 and 1 for banking instruction,
1325 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1326 caused stop processing pCodes after a inline assembly block,
1327 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1329 registers when it shouldn't,
1330 * src/pic16/ralloc.c (allocReg): add preliminary support for
1331 supporting a limited set of temporary registers,
1333 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1335 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

4338 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4340 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4341 loaded with the linker search paths (-L arguments) and the libraries
4342 to be linked with the current source (-l arguments). Changes
4343 currently will affect only the pic16 port.
4344 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4345 include path the port specific paths and port specific libraries,
4346 * gplink command now contains the $3 argument,
4347 * src/pic16/device.h,
4348 * src/pic16/device.c,: structure PIC_device is made public and
4349 renamed to PIC16_device, the same for variable Pics which is renamed

4364 Documenting changes from previous commits.
4365 * configure.in (version 1.56),
4366 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4367 when generating output files to configure the pic16 library,
4368 but now I've commented it out, since gputils aren't installed in the
4369 SF compile farm, so library won't compile
4371 * device/lib/Makefile.in (version 1.56): initially I've added in
4372 target 'all' the prerequestive 'model-pic16' so it compiled the
4373 pic16 library, but now I've commented it out for the same reasons
4375 * added targets 'model-pic16' and 'objects-pic16' to compile the
4377 * added target 'port-specific-objects-pic16' to handle the
4378 generated libraries and copy them into the build/ directory
4379 * added target 'clean-intermediate-pic16' to clean intermediate
4380 files into pic16 directory
4381 * in target 'installdirs' added line to create directory pic16 in
4382 the installation path
4384 * device/include/Makefile.in (version 1.11): in target 'install'
4385 added lines to copy all header files to installation path,
4386 * in target 'installdirs' added line create directory for pic16
4387 headers in the installation path

4402 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4403 option so that it actually works. Made it specific to the z80, since
4404 the gbz80 doesn't have these kinds of I/O ports.
4406 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4408 * device/include/z180.h,

4430 Mainly changes to support compilation of the device libraries
4431 * src/pic16/device.c: stack is allocated via symbol and not
4432 via literal number. The symbol is placed in the corresponding
4433 position of the data ram
4434 * (pic16_dump_section): relocatable and absolute uninitialized
4435 data are now emitted in sorted order to reduce section naming,
4436 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4437 weren't marked as being in the access bank,
4439 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4441 Added portion of GNU PIC Library under the directory
4442 device/include/pic16 and device/lib/pic16. These files
4443 contain the declarations of SFRs for the PIC18Fxx2 devices.
4444 The directory is initialized via configure from toplevel.
4446 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4448 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4474 all over. Telling LaTeX to be less strict with word spacing
4475 to better keep the right margin. Changed some notes about
4476 maintainance of the ports in section 3.2.1 - is it OK like this?
4478 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4487 processor registers declared internally by the port are emitted in
4488 the translation as equates,
4489 * src/pic16/gen.c: inline code is passed unprocessed to the

4515 UPPER for immediate operands,
4516 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4518 * src/pic16/peeph.def: all peepholes with movff are commented out,
4519 because there is a problem in the pcode peep optimizer,
4520 * src/pic16/ralloc.c: the register allocator can now reuse local

4613 include information about variables allocated to the overlay
4616 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4618 * as/mcs51/lkmain.c: Help about -Y option

4630 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4632 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4633 (default behaviour).
4635 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4637 A python script to validate compiler diagnostic messages. It can be
4638 used to verify that sdcc complains about bad c source code and
4639 gives a good location of the error.
4640 * support/valdiag/Makefile,
4641 * support/valdiag/valdiag.py,
4642 * support/valdiag/tests/*
4644 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4657 * src/common.h: added ifndef/define/endif macros
4658 around the header file.
4659 Bug reported from Jesus Calvino-Fraga
4661 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4663 * sdcc.spec: updated
4664 * device/include/Makefile.in: don't install CVS directories
4665 * device/lib/Makefile.in: added removal of CVS directories after install
4666 * doc/Makefile: fixed install, added local_icons
4667 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4668 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4669 * src/ds390/gen.c (genRightShift): fixed bug #870788
4670 * src/SDCCast.c (decorateType): fixed bug #870781
4672 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4674 PIC16 port related changes:
4675 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4676 added variable stackPos,
4678 * gen.c: genCall, assignResultValue: added support for
4679 pushing/retrieving function parameters to/from stack,
4680 genFunction,genEndFunction: setup stack frame for the
4682 genAddrOf: will be changed according to bug 863624
4684 * added files genutils.c and genutils.h which contain gen*
4685 debugged and optimised functions extracted from gen.c
4687 * glue.c: added variable 'externs' which holds extern symbols,
4688 pic16emitRegularMap: is modified to properly handle relocatable
4689 symbols under the new scheme,
4690 pic16createInterruptVect: is modified
4691 pic16printPublics: is modified to emit 'global' assembler directives,
4692 added pic16_printExterns to print extern symbols,
4693 pic16glue: initializes stack/frame pointer in the beginning of
4694 the assembly output. Temporary hack, will be corrected later,
4695 because gplink yet does not support stack and SDCC does not
4696 yet support a type of crt0.o object to create the final binary.
4698 * Removed many lines that contain 8051 legacy code.
4699 * The code is finally placed under a 'code' directive.
4700 * Added port specific options.
4702 * _process_pragma: simplified since now we do not need *special*
4703 include file to define SFR registers. But a separate header
4704 will be needed. This will be developed later.
4705 * _pic16_parseOptions: added, parses port specific options:
4706 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4707 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4708 --preplace-udata-with=
4710 * _pic16_setDefaultOptions: modified to initialize section names,
4711 but hack is temporarly out of order since it needs improvement.
4712 * _pic16_genAssemblerPreamble: configuration words are emitted by
4713 their address instead of their name. This part is incomplete and
4714 supports only the 18Fxx2 devices. Other devices will emit an error
4715 during assembly since they do not contain the same set of config
4717 * _pic16_genIVT: is modified,
4719 * pcode.c: added definitions for some hardware registers that are needed
4721 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4722 All PCI entries are updated. Now LFSR is supported.
4723 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4724 * added pic16_newpCodeOpLit2 to support instructions with
4725 two literal arguments
4726 * pic16_pCode2str: corrected code that emits assembler instructions
4727 with two literal operands and those that have an access bit modifier
4728 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4729 this fixes a bug which caused some labels to be lost, when an
4730 assembler directive was added, i.e. banksel,
4731 * pic16_FixRegisterBanking: improved logic that causes the insertion
4733 * InlineFunction: functions that are called once, are not any more
4734 inlined. This can be a port option in the future,
4736 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4738 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4739 hold the corresponding uninitialized symbols,
4740 * pic16_allocProcessorRegister: registers have explicit marked the
4742 * pic16_allocInternalRegister: registers are explicit marked as
4744 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4745 processing list, so bit registers were lost,
4748 * ralloc.h: added field 'accessBank' and original symbol operand
4749 in register definition,
4750 * removed the field isMapped from register definition,
4752 ** Several functions have been removed from various sources:
4753 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4754 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4755 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4756 pic16_assignRelocatableRegisters
4758 ** others have been introduced:
4759 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4760 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4762 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4764 * support/scripts/inc2h.pl: changed definition of BIT_AT
4765 to emit 'sbit at' instead of 'bit at'. This was a request.
4767 PIC16 port related preliminary changes:
4768 * gen.c: prefixed function popRegFromString with
4769 pic16_ and all references to it corrected
4770 * pcode.c: all pic16_pc_* hardware registers prefixed
4771 with underscore (_),
4772 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4773 * ralloc.c: newReg(): when register is REG_SFR then
4774 set address to rIdx,
4775 pic16_allocProcessorRegister(): marks register wasUsed=0
4776 pic16_writeUsedRegs(): added a call to assign processor
4777 registers via pic16_assignFixedRegisters
4779 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4781 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4782 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4783 variables in unused register banks. Also the SSEG is placed
4784 wherever there is enough space for it, and IDATA can be anywhere
4785 in internal RAM. For now compile using -Wl-Y[stack_size].
4786 The mem file is different for this option as well, since it
4787 makes no sense of talking about DSEG lenght.
4789 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4791 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4792 in certain cases, e.g. when ROM assignment, patch provided
4793 from Albert den Haan.
4795 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5818 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5819 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5820 type for bits was changed. It resulted in bit variables becoming

5838 A few small changes that speed up the peephole optimizer.
5842 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5844 Try to make the peephole optimizer smarter by maintaining
5845 an association between the assembly source code and the
5846 iCodes that originated them. Put this information to use
5847 with a new peephole rule condition "notVolatile" so that
5848 the rules can be aggressive yet still safe.
5853 * src/mcs51/peeph.def
5855 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5859 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5860 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5861 if the left or right operand symbols have the accuse flag set.
5863 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5865 Changed the type of the result of the ! (NOT) operator to char;
5866 previously it returned the same type as the source. This allows
5867 us to eliminate all the genFloatNot functions (all of its target
5868 implementations were very buggy) since !float can use the same
5871 * src/SDCCicode.c (ast2iCode): ! returns char

5880 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5881 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5882 during interrupts. Ensure WSAVE is located at a shared bank address.
5883 2. Fixed page selection in some places
5884 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5885 the registers name strings.
5886 4. Fixed "signed / unsigned compare" compiler warnings.
5887 5. The PIC port manages its own allocation of the general purpose
5888 registers, but makes no attempt to reuse them. As a result when
5889 compiling it soon runs out of general purpose registers. Some
5890 additional code was added to the files pcode.c and device.c to walk
5891 through the function call tree and rename the registers so that they
5901 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5908 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5910 Made bitfield a distinct type from bit so that bitfields
5911 convert as per ANSI C and bits retain their traditional
5912 boolean style behaviour. Implemented bitfield support in
5920 * src/ds390/gen.c: bit v bitfield split
5921 * src/z80/gen.c: New support for bitfields
5922 * support/regression/tests/bitfields.c: reenabled z80,
5925 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5927 Rules 246.x, 247.x relate to bitfields, the others speed up
5928 access to xdata mapped I/O devices.
5930 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5932 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5934 Cleaned up genPackBits and genUnpackBits and added two helper

5944 Fixed bug #748310 (pointer to function type mishandled when the
5945 function name is omitted). Also fixed a SIGSEGV when a function
5946 attribute (reentrant, etc) is used on a non-function or on a
5947 function but misplaced before the parameter list.

5976 Made the constant following the "interrupt" keyword optional. If
5977 omitted, the function will not automatically be given an entry
5978 in the interrupt vector table (similar to #pragma NOIV, but
5979 less syntacticly kludgy). The interrupt number is also now
5980 range checked. Also fixed a bug in the high order bit example
5987 * support/Util/SDCCerr.c

6513 the compiler with no port specified on command line, a default
6514 port is selected with the new macro DEFAULT_PORT which is
6515 defined in port.h, in setDefaultOptions() linkOptions is removed
6516 from initialization assignment, since now it is a set,
6517 parseCmdLine uses setParseWithComma for linkOptions, in

7586 2003-01-04 <johan AT balder>
7588 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7590 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7591 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7593 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7600 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7601 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7603 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7604 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7606 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7608 * in \sdcc\as\mcs51\ changed these files in order to create an
7609 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7610 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7611 following files to include the previous two files: aslink.dsp,
7612 Makefile.aslink, Makefile.bcc, and Makefile.in.
7614 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7615 .adb instead of .cdb
7617 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7619 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7620 value from option --iram-size.
7622 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7624 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7627 2002-09-18 <wiml AT hhhh.org>
7629 * SDCClrange.h: exposed setFromRange() and setToRange()
7630 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7631 packRegsForAccUse() (bug 542397)
7632 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7633 multiple times and emitting the fetch operations more than once
7634 added aopGetUsesAcc() function to allow binary operators to
7635 fetch their operands in the correct order; made genMinus() emit
7636 compact code for X = LITERAL - Y
7638 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7639 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7640 sprintf() in line 1267.
7642 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7643 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7646 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7647 Changes to aslink (All the changes are marked with 'JCF'):
7649 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7652 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7653 area BSEG. Also moves, if possible, the DATA area down into the internal
7654 ram so more space is available.
7656 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7659 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7660 not bytes. Function summary() which creates a memory usage summary
7661 file with extension .mem. Reports of overlaping stack and small stack
7662 size. If the space for the stack is less than 16 bytes aslink trows a
7665 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7666 the 8051. Option 'y' for memory summary output file.
7668 Changes to sdcc (All the changes are marked with 'JCF'):
7670 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7672 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7673 overlaying area for it (uses RegBankUsed[4]).
7675 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7676 bank zero as used by default. By default aslink locates the stack
7677 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7678 the creation of the .mem file. Delegates the allocation of data area
7679 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7680 the begining of the stack area to aslink.
7682 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7683 glue() in SDCCglue.c creates an area for it.
7685 2002-09-03 Borut Razem <borut.razem AT siol.net>
7686 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7687 sdcc/src/pic/glue.c:
7688 introduced atexit() handler for teporay files removal in case of
7689 errors, assertions, ...
7691 2002-08-29 Borut Razem <borut.razem AT siol.net>
7692 * sdcc/support/cpp2/auto-host_vc_in.h:
7693 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7694 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7695 Maybe there is a similar problem with BORLANDC? It should be checked!
7697 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7698 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7699 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7700 was not executed, and the compiler (cl) launched a warning:
7701 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7703 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7704 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7706 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7707 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7709 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7710 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7711 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7712 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7713 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7714 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7715 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7716 - added Release configuration in VS projects
7717 - review of compiler an linker options
7718 - VC .exe files are generated in bin_vc directory, not to interfere
7719 with binaries generated from other projects (cygwin, mingw, bcc ...)
7721 * sdcc/src/yacc.dsp: added
7723 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7724 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7725 and insert the version number definitions from .version
7727 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7729 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7730 added - genarate auto-host.h using auto-host_vc_in.h as template
7733 removed from CVS, generated automatically
7735 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7736 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7738 2002-08-11 Borut Razem <borut.razem AT siol.net>
7739 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7741 2002-08-10 Borut Razem <borut.razem AT siol.net>
7742 * src/SDCCmain.c (main):
7743 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7744 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7745 The consequence was that some temporary files were not removed.
7748 unification of code in functions tempfilename() and tempfile():
7749 function tempnam() is defined in Visual Studio 6.0 and .NET
7751 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7753 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7754 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7755 - removed compiler command line option /WX: Treats all warnings as errors
7756 - update a list of source files, included into the project
7758 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7759 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7760 changed project type to Generic Project so that can be correcly converted to VS.NET project
7762 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7764 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7766 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7768 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7769 added return 0 statements after assert() to make compiler happy
7771 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7772 added newline in the def file to keep MSC compiler satisfied
7774 * sdcc/src/z80/gen.c:
7775 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7776 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7777 - solved MSC error in function aopDump()
7779 * sdcc_vc.h: define PREFIX as "\\sdcc"
7781 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7782 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7784 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7785 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7786 - Rewrote the register banking algorithm.
7787 - Added pCode live-range analysis to registers (for now, only non-used and
7788 singly-used registers optimized away)
7790 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7792 * 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.
7794 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7795 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7797 2002-04-22 Michael Hope <michaelh AT vroom>

7811 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
7813 * src/z80/peeph.def: Added transpose redundent load rule.
7815 * src/z80/main.c: Added force callee saves for jaune.
7817 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7819 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7821 2002-03-28 Johan Knol <johan AT balder>
7823 * src/SDCCval.c: fixed bug #532436
7825 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7827 Added "char *Processor" field to the port structure.
7830 Added -p option. Allows port dependent processor to be specified.
7833 Initialized the new field char *Processor field to NULL in all ports
7836 Compiler generated registers for interrupt context saving
7837 were not getting allocated.
7839 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7842 Fixed left shift. Will promote the left side of a left shift
7843 if a) left shifting more than size of operand or b) when assigned
7844 to something size > size of left side
7846 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7848 tons of changes. Register allocation has been
7849 rewritten. Added customization for the various PICs. Flow
7850 analysis is restructured. ...
7856 Added. device.c is a PIC port hack to accomodate variations
7859 2002-03-13 Michael Hope <michaelh AT vroom>
7861 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7863 2002-03-04 johanknol <johanknol AT manik>
