445 if condition == CARRY)
446 * (genCmp): adapted to new genSkipc semantics
447 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
448 on rIfx (genCmp was broken)
450 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
452 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
453 * src/z80/main.c (_keywords[]),
454 * src/SDCCglobal.h (struct options),
456 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
457 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
458 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
459 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
460 always available in leading double underscore form. The C99 support is
461 mostly missing, but it's a start.
462 * support/regression/tests/bug-227710.c: fixed nonconforming use of
463 reserved identifier "__data".
465 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

473 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
475 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
478 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

506 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
507 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
508 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
509 immedDom() returning wrong block; probably fixes bug #1160833)
511 2005-03-20 Borut Razem <borut.razem AT siol.net>
513 * support/scripts/inc2h.pl: WIN32 port

533 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
536 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
538 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
539 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
541 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
543 * device/lib/printf_large.c: removed inline assembly for portability and
544 readability. Use printf_fast if speed or size are more important.
545 * src/pic16/gen.c: removed conditions around use of DEBUGpc
546 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
548 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
550 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
551 prevent compiler warning
553 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
555 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
556 moved to level 0 and declared as static. Also they are explicit
557 placed in access bank. This was necessery because some times they
558 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
559 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
560 optimizations. Currently only compare to unsigned char is implemented,
561 * src/pic16/gen.c: added fReturnIdx array,
562 * (struct resolvedIfx) is moved to gen.h and made public,
563 * (struct _G): added sregsAlloc and sregsAllocSet fields,
564 * (aopForSym): added an optimization to directly store in stack of
565 the operand of a SEND iCode,
566 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
567 but as registers instead (AOP_REG) using the fReturnIdx array,
568 * (pic16_freeAsmop): remove the freed register from the
570 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
572 * (pic16_popGetTempRegCond): changed function prototype, now
573 function takes also a bitVector argument v which holds the current
574 set of registers that are allocated for stack access by aopForSym,
575 registers allocated in aopForSym for accessing stack symbols are not
576 any more part of the functions usedRegs field,
577 * (genCall): some times aopOp is called for a stack variable to be
578 send, aopForSym might perform the push, if this is true make sure
579 that genCall doesn't push the variable twice by testing _G.resDirect,
580 * (genFunction): changed testing for unspecified interrupt number
581 from 256 to INTNO_UNSPEC,
582 * modified selection scheme of frame pointer generation. Previously
583 if function did use local registers a frame pointer was generated,
584 now a frame pointer is generated only if function has arguments
585 (that need PLUSW2 register access), or has stack arguments, or the
586 compiler is not instructed to omit the frame pointer,
587 * (genEndFunction): before restoring local registers that were saved
588 in the function preamble, also restore the registers that *might*
589 have been allocated for stack access,
590 * (genRet): removed some old comments,
591 * (genCmp, the active (RN's) version): added a call to the
592 pic16_genCmp_special function to perform the compare with a more
593 robust and optimized way,
594 * (genInline): a feature has been added in inline code generation,
595 which allows a wildcard variable substitution when writing inline
596 assembly. Code is incomplete and experimental therefore undocumented,
597 * (genCast): changed order of aopOp for result and right to allow
598 aopForSym to directly load the result if possible,
599 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
600 perform an optimized compare on some selected special occasions,
601 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
602 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
603 generate an IVT any more,
604 * src/pic16/main.c (pic16_optionsTable): added command line option
606 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
607 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
609 * src/pic16/NOTES: Raphael Neider added in list of active developers
610 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
611 jumptable_end to prevent bug #,
612 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
613 inCond and outCond fields,
614 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
615 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
616 turn off register spilling,
617 * (packRegsForOneUse): synced with other ports' versions although it
618 is not used currently,
619 * (pic16_packRegisters): added an optimization while reading
620 structure bitfields, some registers may be saved (malloc code is
621 decreased by 80 bytes)
623 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
625 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
626 left is a bitfield, if yes, then don't optimize assignment. Perhaps
627 this can be optimized more?
629 2005-03-10 Raphael Neider <rneider AT web.de>
631 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
632 genNearPointerGet): (hopefully) fixed access to bitfields via
633 pointers (p->bitN = x; and x = p->bitN; failed)

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

1268 generated for switch statements. For now you need to set the
1269 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1270 Now 4 algorithms for mcs51 jumptable generation are used:
1271 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1303 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1305 * added libc directory. The current version of LibC contains string
1306 functions, ctype functions and macros and some functions of the
1307 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1308 be extensively tested in the future. Standard disclaimer here.
1309 Library is not automatically build yet. But one can build it by
1310 invoking 'make' inside the libc directory.
1311 * added ADC library under libio. Preliminary version yet.

1320 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1321 * (pic16_storeForReturn): optimized return of 0,
1322 * (genCmp): experimental code for new genCmp which uses PIC18's
1323 special compare&skip instructions. Initial tests fail some times
1324 with variables grater than 1 byte in size, so new code is disabled,
1325 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1327 * (genCast): began a fix to optimize the casting of a bit to another
1328 bit, now assigning a bitfield to another bitfield will fail, sorry,

1336 * (isBankInstruction): modified to return 0 for no banking instruction,
1337 and 1 for banking instruction,
1338 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1339 caused stop processing pCodes after a inline assembly block,
1340 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1341 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary

4351 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4353 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4354 loaded with the linker search paths (-L arguments) and the libraries
4355 to be linked with the current source (-l arguments). Changes
4356 currently will affect only the pic16 port.
4357 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4358 include path the port specific paths and port specific libraries,
4359 * gplink command now contains the $3 argument,
4360 * src/pic16/device.h,
4361 * src/pic16/device.c,: structure PIC_device is made public and
4362 renamed to PIC16_device, the same for variable Pics which is renamed

4377 Documenting changes from previous commits.
4378 * configure.in (version 1.56),
4379 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4380 when generating output files to configure the pic16 library,
4381 but now I've commented it out, since gputils aren't installed in the
4382 SF compile farm, so library won't compile
4384 * device/lib/Makefile.in (version 1.56): initially I've added in
4385 target 'all' the prerequestive 'model-pic16' so it compiled the
4386 pic16 library, but now I've commented it out for the same reasons
4388 * added targets 'model-pic16' and 'objects-pic16' to compile the
4390 * added target 'port-specific-objects-pic16' to handle the
4391 generated libraries and copy them into the build/ directory
4392 * added target 'clean-intermediate-pic16' to clean intermediate
4393 files into pic16 directory
4394 * in target 'installdirs' added line to create directory pic16 in
4395 the installation path
4397 * device/include/Makefile.in (version 1.11): in target 'install'
4398 added lines to copy all header files to installation path,
4399 * in target 'installdirs' added line create directory for pic16
4400 headers in the installation path

4415 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4416 option so that it actually works. Made it specific to the z80, since
4417 the gbz80 doesn't have these kinds of I/O ports.
4419 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4421 * device/include/z180.h,

4445 via literal number. The symbol is placed in the corresponding
4446 position of the data ram
4447 * (pic16_dump_section): relocatable and absolute uninitialized
4448 data are now emitted in sorted order to reduce section naming,
4449 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4450 weren't marked as being in the access bank,

4454 Added portion of GNU PIC Library under the directory
4455 device/include/pic16 and device/lib/pic16. These files
4456 contain the declarations of SFRs for the PIC18Fxx2 devices.
4457 The directory is initialized via configure from toplevel.

4487 all over. Telling LaTeX to be less strict with word spacing
4488 to better keep the right margin. Changed some notes about
4489 maintainance of the ports in section 3.2.1 - is it OK like this?
4491 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4531 * src/pic16/peeph.def: all peepholes with movff are commented out,
4532 because there is a problem in the pcode peep optimizer,
4533 * src/pic16/ralloc.c: the register allocator can now reuse local

4643 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4645 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4646 (default behaviour).
4648 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4650 A python script to validate compiler diagnostic messages. It can be
4651 used to verify that sdcc complains about bad c source code and
4652 gives a good location of the error.
4653 * support/valdiag/Makefile,
4654 * support/valdiag/valdiag.py,
4655 * support/valdiag/tests/*

4672 Bug reported from Jesus Calvino-Fraga
4674 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4676 * sdcc.spec: updated
4677 * device/include/Makefile.in: don't install CVS directories
4678 * device/lib/Makefile.in: added removal of CVS directories after install
4679 * doc/Makefile: fixed install, added local_icons
4680 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4681 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4682 * src/ds390/gen.c (genRightShift): fixed bug #870788
4683 * src/SDCCast.c (decorateType): fixed bug #870781
4685 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4687 PIC16 port related changes:
4688 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4689 added variable stackPos,
4691 * gen.c: genCall, assignResultValue: added support for
4692 pushing/retrieving function parameters to/from stack,
4693 genFunction,genEndFunction: setup stack frame for the
4695 genAddrOf: will be changed according to bug 863624
4697 * added files genutils.c and genutils.h which contain gen*
4698 debugged and optimised functions extracted from gen.c
4700 * glue.c: added variable 'externs' which holds extern symbols,
4701 pic16emitRegularMap: is modified to properly handle relocatable
4702 symbols under the new scheme,
4703 pic16createInterruptVect: is modified
4704 pic16printPublics: is modified to emit 'global' assembler directives,
4705 added pic16_printExterns to print extern symbols,
4706 pic16glue: initializes stack/frame pointer in the beginning of
4707 the assembly output. Temporary hack, will be corrected later,
4708 because gplink yet does not support stack and SDCC does not
4709 yet support a type of crt0.o object to create the final binary.
4711 * Removed many lines that contain 8051 legacy code.
4712 * The code is finally placed under a 'code' directive.
4713 * Added port specific options.
4715 * _process_pragma: simplified since now we do not need *special*
4716 include file to define SFR registers. But a separate header
4717 will be needed. This will be developed later.
4718 * _pic16_parseOptions: added, parses port specific options:
4719 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4720 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4721 --preplace-udata-with=
4723 * _pic16_setDefaultOptions: modified to initialize section names,
4724 but hack is temporarly out of order since it needs improvement.
4725 * _pic16_genAssemblerPreamble: configuration words are emitted by
4726 their address instead of their name. This part is incomplete and
4727 supports only the 18Fxx2 devices. Other devices will emit an error
4728 during assembly since they do not contain the same set of config
4730 * _pic16_genIVT: is modified,
4732 * pcode.c: added definitions for some hardware registers that are needed
4734 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4735 All PCI entries are updated. Now LFSR is supported.
4736 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4737 * added pic16_newpCodeOpLit2 to support instructions with
4738 two literal arguments
4739 * pic16_pCode2str: corrected code that emits assembler instructions
4740 with two literal operands and those that have an access bit modifier
4741 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4742 this fixes a bug which caused some labels to be lost, when an
4743 assembler directive was added, i.e. banksel,
4744 * pic16_FixRegisterBanking: improved logic that causes the insertion
4746 * InlineFunction: functions that are called once, are not any more
4747 inlined. This can be a port option in the future,
4749 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4751 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4752 hold the corresponding uninitialized symbols,
4753 * pic16_allocProcessorRegister: registers have explicit marked the
4755 * pic16_allocInternalRegister: registers are explicit marked as
4757 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4758 processing list, so bit registers were lost,
4761 * ralloc.h: added field 'accessBank' and original symbol operand
4762 in register definition,
4763 * removed the field isMapped from register definition,
4765 ** Several functions have been removed from various sources:
4766 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4767 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4768 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4769 pic16_assignRelocatableRegisters
4771 ** others have been introduced:
4772 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4773 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4775 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4777 * support/scripts/inc2h.pl: changed definition of BIT_AT
4778 to emit 'sbit at' instead of 'bit at'. This was a request.
4780 PIC16 port related preliminary changes:
4781 * gen.c: prefixed function popRegFromString with
4782 pic16_ and all references to it corrected
4783 * pcode.c: all pic16_pc_* hardware registers prefixed
4784 with underscore (_),
4785 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4786 * ralloc.c: newReg(): when register is REG_SFR then
4787 set address to rIdx,
4788 pic16_allocProcessorRegister(): marks register wasUsed=0
4789 pic16_writeUsedRegs(): added a call to assign processor
4790 registers via pic16_assignFixedRegisters
4792 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4794 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4795 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4796 variables in unused register banks. Also the SSEG is placed
4797 wherever there is enough space for it, and IDATA can be anywhere
4798 in internal RAM. For now compile using -Wl-Y[stack_size].
4799 The mem file is different for this option as well, since it
4800 makes no sense of talking about DSEG lenght.
4802 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4804 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4805 in certain cases, e.g. when ROM assignment, patch provided
4806 from Albert den Haan.
4808 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4950 SDCC_NOGENRAMCLEAR to disable this.
4951 * src/mcs51/peephole.def,
4952 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4953 (allows non-interrupt and interrupt code to safely compete for a resource
4954 without the non-interrupt code having to disable interrupts)
4956 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4958 * src/SDCCicode.c (geniCodeAdd),

5051 it breaks with bitfields, extern declarations, and gcse analysis.
5052 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5053 could be assigned through a pointer, so don't complain.

5831 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5832 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

5851 A few small changes that speed up the peephole optimizer.
5855 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5857 Try to make the peephole optimizer smarter by maintaining
5858 an association between the assembly source code and the
5859 iCodes that originated them. Put this information to use
5860 with a new peephole rule condition "notVolatile" so that
5861 the rules can be aggressive yet still safe.
5866 * src/mcs51/peeph.def
5868 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5872 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5873 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5874 if the left or right operand symbols have the accuse flag set.
5876 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5878 Changed the type of the result of the ! (NOT) operator to char;
5879 previously it returned the same type as the source. This allows
5880 us to eliminate all the genFloatNot functions (all of its target
5881 implementations were very buggy) since !float can use the same
5884 * src/SDCCicode.c (ast2iCode): ! returns char

5893 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5894 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5895 during interrupts. Ensure WSAVE is located at a shared bank address.
5896 2. Fixed page selection in some places
5897 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5898 the registers name strings.
5899 4. Fixed "signed / unsigned compare" compiler warnings.
5900 5. The PIC port manages its own allocation of the general purpose
5901 registers, but makes no attempt to reuse them. As a result when
5902 compiling it soon runs out of general purpose registers. Some
5903 additional code was added to the files pcode.c and device.c to walk
5904 through the function call tree and rename the registers so that they
5914 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5915 genPlus() & genMinus() when the result is the same as left or right

5921 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5923 Made bitfield a distinct type from bit so that bitfields
5924 convert as per ANSI C and bits retain their traditional
5925 boolean style behaviour. Implemented bitfield support in
5933 * src/ds390/gen.c: bit v bitfield split
5934 * src/z80/gen.c: New support for bitfields
5935 * support/regression/tests/bitfields.c: reenabled z80,
5938 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5940 Rules 246.x, 247.x relate to bitfields, the others speed up
5941 access to xdata mapped I/O devices.
5943 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5945 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5947 Cleaned up genPackBits and genUnpackBits and added two helper
5948 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5949 for literal assignments in genPackBits (thanks to Frieder for
5955 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5957 Fixed bug #748310 (pointer to function type mishandled when the
5958 function name is omitted). Also fixed a SIGSEGV when a function
5959 attribute (reentrant, etc) is used on a non-function or on a
5960 function but misplaced before the parameter list.
5962 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5964 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5989 Made the constant following the "interrupt" keyword optional. If
5990 omitted, the function will not automatically be given an entry
5991 in the interrupt vector table (similar to #pragma NOIV, but
5992 less syntacticly kludgy). The interrupt number is also now
5993 range checked. Also fixed a bug in the high order bit example

6525 support for the PIc16 port in the ports table, when executing
6526 the compiler with no port specified on command line, a default
6527 port is selected with the new macro DEFAULT_PORT which is
6528 defined in port.h, in setDefaultOptions() linkOptions is removed
6529 from initialization assignment, since now it is a set,
6530 parseCmdLine uses setParseWithComma for linkOptions, in
6531 linkEdit() linkOptions are accessed with new function indexSet()

7593 * src/SDCCicode.c: fixed array add
7595 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7596 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7597 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7599 2003-01-04 <johan AT balder>
7601 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7603 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7604 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7606 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7607 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7613 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7614 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7616 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7617 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7619 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7621 * in \sdcc\as\mcs51\ changed these files in order to create an
7622 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7623 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7624 following files to include the previous two files: aslink.dsp,
7625 Makefile.aslink, Makefile.bcc, and Makefile.in.
7627 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7628 .adb instead of .cdb
7630 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7632 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7633 value from option --iram-size.
7635 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7637 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7640 2002-09-18 <wiml AT hhhh.org>
7642 * SDCClrange.h: exposed setFromRange() and setToRange()
7643 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7644 packRegsForAccUse() (bug 542397)
7645 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7646 multiple times and emitting the fetch operations more than once
7647 added aopGetUsesAcc() function to allow binary operators to
7648 fetch their operands in the correct order; made genMinus() emit
7649 compact code for X = LITERAL - Y
7651 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7652 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7653 sprintf() in line 1267.
7655 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7656 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7659 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7660 Changes to aslink (All the changes are marked with 'JCF'):
7662 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7665 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7666 area BSEG. Also moves, if possible, the DATA area down into the internal
7667 ram so more space is available.
7669 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7672 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7673 not bytes. Function summary() which creates a memory usage summary
7674 file with extension .mem. Reports of overlaping stack and small stack
7675 size. If the space for the stack is less than 16 bytes aslink trows a
7678 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7679 the 8051. Option 'y' for memory summary output file.
7681 Changes to sdcc (All the changes are marked with 'JCF'):
7683 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7685 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7686 overlaying area for it (uses RegBankUsed[4]).
7688 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7689 bank zero as used by default. By default aslink locates the stack
7690 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7691 the creation of the .mem file. Delegates the allocation of data area
7692 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7693 the begining of the stack area to aslink.
7695 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7696 glue() in SDCCglue.c creates an area for it.
7698 2002-09-03 Borut Razem <borut.razem AT siol.net>
7699 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7700 sdcc/src/pic/glue.c:
7701 introduced atexit() handler for teporay files removal in case of
7702 errors, assertions, ...
7704 2002-08-29 Borut Razem <borut.razem AT siol.net>
7705 * sdcc/support/cpp2/auto-host_vc_in.h:
7706 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7707 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7708 Maybe there is a similar problem with BORLANDC? It should be checked!
7710 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7711 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7712 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7713 was not executed, and the compiler (cl) launched a warning:
7714 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7716 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7717 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7719 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7720 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7722 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7723 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7724 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7725 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7726 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7727 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7728 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7729 - added Release configuration in VS projects
7730 - review of compiler an linker options
7731 - VC .exe files are generated in bin_vc directory, not to interfere
7732 with binaries generated from other projects (cygwin, mingw, bcc ...)
7734 * sdcc/src/yacc.dsp: added
7736 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7737 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7738 and insert the version number definitions from .version
7740 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7742 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7743 added - genarate auto-host.h using auto-host_vc_in.h as template
7746 removed from CVS, generated automatically
7748 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7749 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7751 2002-08-11 Borut Razem <borut.razem AT siol.net>
7752 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7754 2002-08-10 Borut Razem <borut.razem AT siol.net>
7755 * src/SDCCmain.c (main):
7756 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7757 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7758 The consequence was that some temporary files were not removed.
7761 unification of code in functions tempfilename() and tempfile():
7762 function tempnam() is defined in Visual Studio 6.0 and .NET
7764 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7766 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7767 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7768 - removed compiler command line option /WX: Treats all warnings as errors
7769 - update a list of source files, included into the project
7771 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7772 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7773 changed project type to Generic Project so that can be correcly converted to VS.NET project
7775 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7777 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7779 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7781 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7782 added return 0 statements after assert() to make compiler happy
7784 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7785 added newline in the def file to keep MSC compiler satisfied
7787 * sdcc/src/z80/gen.c:
7788 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7789 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7790 - solved MSC error in function aopDump()
7792 * sdcc_vc.h: define PREFIX as "\\sdcc"
7794 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7795 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7797 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7798 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7799 - Rewrote the register banking algorithm.
7800 - Added pCode live-range analysis to registers (for now, only non-used and
7801 singly-used registers optimized away)
7803 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7805 * 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.
7807 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7808 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7810 2002-04-22 Michael Hope <michaelh AT vroom>
7812 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.

7826 * src/z80/peeph.def: Added transpose redundent load rule.
7828 * src/z80/main.c: Added force callee saves for jaune.
7830 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7832 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7834 2002-03-28 Johan Knol <johan AT balder>
7836 * src/SDCCval.c: fixed bug #532436
7838 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7840 Added "char *Processor" field to the port structure.
7843 Added -p option. Allows port dependent processor to be specified.
7846 Initialized the new field char *Processor field to NULL in all ports
7849 Compiler generated registers for interrupt context saving
7850 were not getting allocated.
7852 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7855 Fixed left shift. Will promote the left side of a left shift
7856 if a) left shifting more than size of operand or b) when assigned
