474 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
475 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies

479 2005-03-20 Borut Razem <borut.razem AT siol.net>
481 * support/scripts/inc2h.pl: WIN32 port
483 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

487 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
489 * device/include/stdint.h: added
490 * device/lib/abs.c: added
491 * device/lib/labs.c: added
492 * device/include/stdlib.h: added abs() and labs() prototypes
493 * device/lib/libsdcc.lib: added abs and labs
494 * device/include/float.h,
495 * device/lib/_fsmul.c,
496 * device/lib/printf_fast.c,
497 * device/lib/printf_tiny.c: updated comments
499 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
501 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
504 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
506 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
507 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
509 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
511 * device/lib/printf_large.c: removed inline assembly for portability and
512 readability. Use printf_fast if speed or size are more important.
513 * src/pic16/gen.c: removed conditions around use of DEBUGpc
514 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
516 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
518 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
519 prevent compiler warning
521 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
523 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
524 moved to level 0 and declared as static. Also they are explicit
525 placed in access bank. This was necessery because some times they
526 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
527 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
528 optimizations. Currently only compare to unsigned char is implemented,
529 * src/pic16/gen.c: added fReturnIdx array,
530 * (struct resolvedIfx) is moved to gen.h and made public,
531 * (struct _G): added sregsAlloc and sregsAllocSet fields,
532 * (aopForSym): added an optimization to directly store in stack of
533 the operand of a SEND iCode,
534 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
535 but as registers instead (AOP_REG) using the fReturnIdx array,
536 * (pic16_freeAsmop): remove the freed register from the
538 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
540 * (pic16_popGetTempRegCond): changed function prototype, now
541 function takes also a bitVector argument v which holds the current
542 set of registers that are allocated for stack access by aopForSym,
543 registers allocated in aopForSym for accessing stack symbols are not
544 any more part of the functions usedRegs field,
545 * (genCall): some times aopOp is called for a stack variable to be
546 send, aopForSym might perform the push, if this is true make sure
547 that genCall doesn't push the variable twice by testing _G.resDirect,
548 * (genFunction): changed testing for unspecified interrupt number
549 from 256 to INTNO_UNSPEC,
550 * modified selection scheme of frame pointer generation. Previously
551 if function did use local registers a frame pointer was generated,
552 now a frame pointer is generated only if function has arguments
553 (that need PLUSW2 register access), or has stack arguments, or the
554 compiler is not instructed to omit the frame pointer,
555 * (genEndFunction): before restoring local registers that were saved
556 in the function preamble, also restore the registers that *might*
557 have been allocated for stack access,
558 * (genRet): removed some old comments,
559 * (genCmp, the active (RN's) version): added a call to the
560 pic16_genCmp_special function to perform the compare with a more
561 robust and optimized way,
562 * (genInline): a feature has been added in inline code generation,
563 which allows a wildcard variable substitution when writing inline
564 assembly. Code is incomplete and experimental therefore undocumented,
565 * (genCast): changed order of aopOp for result and right to allow
566 aopForSym to directly load the result if possible,
567 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
568 perform an optimized compare on some selected special occasions,
569 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
570 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
571 generate an IVT any more,
572 * src/pic16/main.c (pic16_optionsTable): added command line option
574 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
575 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
577 * src/pic16/NOTES: Raphael Neider added in list of active developers
578 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
579 jumptable_end to prevent bug #,
580 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
581 inCond and outCond fields,
582 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
583 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
584 turn off register spilling,
585 * (packRegsForOneUse): synced with other ports' versions although it
586 is not used currently,
587 * (pic16_packRegisters): added an optimization while reading
588 structure bitfields, some registers may be saved (malloc code is
589 decreased by 80 bytes)
591 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
593 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
594 left is a bitfield, if yes, then don't optimize assignment. Perhaps
595 this can be optimized more?
597 2005-03-10 Raphael Neider <rneider AT web.de>
599 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
600 genNearPointerGet): (hopefully) fixed access to bitfields via
601 pointers (p->bitN = x; and x = p->bitN; failed)

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

1236 generated for switch statements. For now you need to set the
1237 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1238 Now 4 algorithms for mcs51 jumptable generation are used:
1239 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1271 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1273 * added libc directory. The current version of LibC contains string
1274 functions, ctype functions and macros and some functions of the
1275 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1276 be extensively tested in the future. Standard disclaimer here.
1277 Library is not automatically build yet. But one can build it by
1278 invoking 'make' inside the libc directory.

1289 * (pic16_storeForReturn): optimized return of 0,
1290 * (genCmp): experimental code for new genCmp which uses PIC18's
1291 special compare&skip instructions. Initial tests fail some times
1292 with variables grater than 1 byte in size, so new code is disabled,
1293 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1295 * (genCast): began a fix to optimize the casting of a bit to another
1296 bit, now assigning a bitfield to another bitfield will fail, sorry,

1304 * (isBankInstruction): modified to return 0 for no banking instruction,
1305 and 1 for banking instruction,
1306 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1307 caused stop processing pCodes after a inline assembly block,
1308 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1309 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1310 registers when it shouldn't,
1311 * src/pic16/ralloc.c (allocReg): add preliminary support for
1312 supporting a limited set of temporary registers,
1314 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1316 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1317 genDataPointerSet): ensure assignments always copy in MSB to LSB
1319 (loadRegFromAop): recognize CLRH optimization,
1320 (genFunction): optimize RECEIVE iCodes in reentrant functions
1322 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1324 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1325 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1327 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
1328 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
1329 contiguous with data

1333 * device/lib/_gptrget.c (_gptrget),
1334 * device/lib/_gptrgetc.c (_gptrgetc),
1335 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1336 instead of sjmp to ret
1337 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided

4319 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4321 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4322 loaded with the linker search paths (-L arguments) and the libraries
4323 to be linked with the current source (-l arguments). Changes
4324 currently will affect only the pic16 port.
4325 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4326 include path the port specific paths and port specific libraries,
4327 * gplink command now contains the $3 argument,
4328 * src/pic16/device.h,
4329 * src/pic16/device.c,: structure PIC_device is made public and
4330 renamed to PIC16_device, the same for variable Pics which is renamed

4345 Documenting changes from previous commits.
4346 * configure.in (version 1.56),
4347 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4348 when generating output files to configure the pic16 library,
4349 but now I've commented it out, since gputils aren't installed in the
4350 SF compile farm, so library won't compile
4352 * device/lib/Makefile.in (version 1.56): initially I've added in
4353 target 'all' the prerequestive 'model-pic16' so it compiled the
4354 pic16 library, but now I've commented it out for the same reasons
4356 * added targets 'model-pic16' and 'objects-pic16' to compile the
4358 * added target 'port-specific-objects-pic16' to handle the
4359 generated libraries and copy them into the build/ directory
4360 * added target 'clean-intermediate-pic16' to clean intermediate
4361 files into pic16 directory
4362 * in target 'installdirs' added line to create directory pic16 in
4363 the installation path

4366 added lines to copy all header files to installation path,
4367 * in target 'installdirs' added line create directory for pic16
4368 headers in the installation path

4384 option so that it actually works. Made it specific to the z80, since
4385 the gbz80 doesn't have these kinds of I/O ports.
4387 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4389 * device/include/z180.h,

4413 via literal number. The symbol is placed in the corresponding
4414 position of the data ram
4415 * (pic16_dump_section): relocatable and absolute uninitialized
4416 data are now emitted in sorted order to reduce section naming,
4417 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4418 weren't marked as being in the access bank,
4420 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4422 Added portion of GNU PIC Library under the directory
4423 device/include/pic16 and device/lib/pic16. These files
4424 contain the declarations of SFRs for the PIC18Fxx2 devices.
4425 The directory is initialized via configure from toplevel.

4456 to better keep the right margin. Changed some notes about
4457 maintainance of the ports in section 3.2.1 - is it OK like this?
4459 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4461 SDCC source changes:
4462 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4496 UPPER for immediate operands,
4497 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4499 * src/pic16/peeph.def: all peepholes with movff are commented out,
4500 because there is a problem in the pcode peep optimizer,
4501 * src/pic16/ralloc.c: the register allocator can now reuse local

4611 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4613 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4614 (default behaviour).
4616 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4618 A python script to validate compiler diagnostic messages. It can be
4619 used to verify that sdcc complains about bad c source code and
4620 gives a good location of the error.
4621 * support/valdiag/Makefile,
4622 * support/valdiag/valdiag.py,
4623 * support/valdiag/tests/*

4640 Bug reported from Jesus Calvino-Fraga
4642 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4644 * sdcc.spec: updated
4645 * device/include/Makefile.in: don't install CVS directories
4646 * device/lib/Makefile.in: added removal of CVS directories after install
4647 * doc/Makefile: fixed install, added local_icons
4648 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4649 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4650 * src/ds390/gen.c (genRightShift): fixed bug #870788
4651 * src/SDCCast.c (decorateType): fixed bug #870781
4653 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4655 PIC16 port related changes:
4656 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4657 added variable stackPos,
4659 * gen.c: genCall, assignResultValue: added support for
4660 pushing/retrieving function parameters to/from stack,
4661 genFunction,genEndFunction: setup stack frame for the
4663 genAddrOf: will be changed according to bug 863624
4665 * added files genutils.c and genutils.h which contain gen*
4666 debugged and optimised functions extracted from gen.c
4668 * glue.c: added variable 'externs' which holds extern symbols,
4669 pic16emitRegularMap: is modified to properly handle relocatable
4670 symbols under the new scheme,
4671 pic16createInterruptVect: is modified
4672 pic16printPublics: is modified to emit 'global' assembler directives,
4673 added pic16_printExterns to print extern symbols,
4674 pic16glue: initializes stack/frame pointer in the beginning of
4675 the assembly output. Temporary hack, will be corrected later,
4676 because gplink yet does not support stack and SDCC does not
4677 yet support a type of crt0.o object to create the final binary.
4679 * Removed many lines that contain 8051 legacy code.
4680 * The code is finally placed under a 'code' directive.
4681 * Added port specific options.
4683 * _process_pragma: simplified since now we do not need *special*
4684 include file to define SFR registers. But a separate header
4685 will be needed. This will be developed later.
4686 * _pic16_parseOptions: added, parses port specific options:
4687 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4688 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4689 --preplace-udata-with=
4691 * _pic16_setDefaultOptions: modified to initialize section names,
4692 but hack is temporarly out of order since it needs improvement.
4693 * _pic16_genAssemblerPreamble: configuration words are emitted by
4694 their address instead of their name. This part is incomplete and
4695 supports only the 18Fxx2 devices. Other devices will emit an error
4696 during assembly since they do not contain the same set of config
4698 * _pic16_genIVT: is modified,
4700 * pcode.c: added definitions for some hardware registers that are needed
4702 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4703 All PCI entries are updated. Now LFSR is supported.
4704 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4705 * added pic16_newpCodeOpLit2 to support instructions with
4706 two literal arguments
4707 * pic16_pCode2str: corrected code that emits assembler instructions
4708 with two literal operands and those that have an access bit modifier
4709 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4710 this fixes a bug which caused some labels to be lost, when an
4711 assembler directive was added, i.e. banksel,
4712 * pic16_FixRegisterBanking: improved logic that causes the insertion
4714 * InlineFunction: functions that are called once, are not any more
4715 inlined. This can be a port option in the future,
4717 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4719 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4720 hold the corresponding uninitialized symbols,
4721 * pic16_allocProcessorRegister: registers have explicit marked the
4723 * pic16_allocInternalRegister: registers are explicit marked as
4725 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4726 processing list, so bit registers were lost,
4729 * ralloc.h: added field 'accessBank' and original symbol operand
4730 in register definition,
4731 * removed the field isMapped from register definition,
4733 ** Several functions have been removed from various sources:
4734 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4735 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4736 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4737 pic16_assignRelocatableRegisters
4739 ** others have been introduced:
4740 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4741 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4743 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4745 * support/scripts/inc2h.pl: changed definition of BIT_AT
4746 to emit 'sbit at' instead of 'bit at'. This was a request.
4748 PIC16 port related preliminary changes:
4749 * gen.c: prefixed function popRegFromString with
4750 pic16_ and all references to it corrected
4751 * pcode.c: all pic16_pc_* hardware registers prefixed
4752 with underscore (_),
4753 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4754 * ralloc.c: newReg(): when register is REG_SFR then
4755 set address to rIdx,
4756 pic16_allocProcessorRegister(): marks register wasUsed=0
4757 pic16_writeUsedRegs(): added a call to assign processor
4758 registers via pic16_assignFixedRegisters
4760 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4762 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4763 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4764 variables in unused register banks. Also the SSEG is placed
4765 wherever there is enough space for it, and IDATA can be anywhere
4766 in internal RAM. For now compile using -Wl-Y[stack_size].
4767 The mem file is different for this option as well, since it
4768 makes no sense of talking about DSEG lenght.
4770 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4772 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4773 in certain cases, e.g. when ROM assignment, patch provided
4774 from Albert den Haan.
4776 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4919 * src/mcs51/peephole.def,
4920 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4921 (allows non-interrupt and interrupt code to safely compete for a resource

5661 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5662 support for standard C idiom of memory mapped variables; for
5663 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5664 to xdata int at 0x1234 tempvar = 1.
5665 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5666 provided by Akiya ISHIDA

5682 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5684 Fixed bug #621531 (const & volatile confusion in the type chain).
5685 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
5686 refer to the const or volatile state of the pointer itself.

5764 * src/mcs51/gen.c (leftRightUseAcc),
5765 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5766 iCode properly now. Use getSize instead of nRegs since a & b
5767 aren't part of the nRegs tally.
5769 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5771 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

5775 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5777 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5778 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5779 fetching of the pointer
5780 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5781 copied from genNearPointerSet()
5782 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5783 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5784 If they pop r0/r1 they must be called in the opposite order than aopOp().
5785 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5786 (resp. --stack-auto), prepared for --xstack

5797 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5799 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5800 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5801 type for bits was changed. It resulted in bit variables becoming
5802 global, which is not permitted in PIC 14 assembly output.
5804 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5806 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5810 Z80 and MCS51 linkers complaint if a public symbol is defined
5811 in more than one library module:
5815 * as/mcs51/Makefile.in
5817 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5819 A few small changes that speed up the peephole optimizer.
5823 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5825 Try to make the peephole optimizer smarter by maintaining
5826 an association between the assembly source code and the
5827 iCodes that originated them. Put this information to use
5828 with a new peephole rule condition "notVolatile" so that
5829 the rules can be aggressive yet still safe.
5834 * src/mcs51/peeph.def
5836 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5840 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5841 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5842 if the left or right operand symbols have the accuse flag set.
5844 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5846 Changed the type of the result of the ! (NOT) operator to char;
5847 previously it returned the same type as the source. This allows
5848 us to eliminate all the genFloatNot functions (all of its target
5849 implementations were very buggy) since !float can use the same
5852 * src/SDCCicode.c (ast2iCode): ! returns char
5853 * src/mcs51/gen.c (genNot, genNotFloat),
5854 * src/ds390/gen.c (genNot, genNotFloat),
5855 * src/z80/gen.c (genNot, genNotFloat),
5856 * src/pic/gen.c (genNot, genNotFloat),
5857 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5859 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5861 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5862 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5863 during interrupts. Ensure WSAVE is located at a shared bank address.
5864 2. Fixed page selection in some places
5865 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5866 the registers name strings.
5867 4. Fixed "signed / unsigned compare" compiler warnings.
5868 5. The PIC port manages its own allocation of the general purpose
5869 registers, but makes no attempt to reuse them. As a result when
5870 compiling it soon runs out of general purpose registers. Some
5871 additional code was added to the files pcode.c and device.c to walk
5872 through the function call tree and rename the registers so that they
5882 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5883 genPlus() & genMinus() when the result is the same as left or right
5885 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5889 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5891 Made bitfield a distinct type from bit so that bitfields
5892 convert as per ANSI C and bits retain their traditional
5893 boolean style behaviour. Implemented bitfield support in
5901 * src/ds390/gen.c: bit v bitfield split
5902 * src/z80/gen.c: New support for bitfields
5903 * support/regression/tests/bitfields.c: reenabled z80,
5906 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5908 Rules 246.x, 247.x relate to bitfields, the others speed up
5909 access to xdata mapped I/O devices.
5911 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5913 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5915 Cleaned up genPackBits and genUnpackBits and added two helper
5916 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5917 for literal assignments in genPackBits (thanks to Frieder for
5923 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5925 Fixed bug #748310 (pointer to function type mishandled when the
5926 function name is omitted). Also fixed a SIGSEGV when a function
5927 attribute (reentrant, etc) is used on a non-function or on a
5928 function but misplaced before the parameter list.
5930 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5932 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5933 * support/Util/SDCCerr.h,
5934 * support/Util/SDCCerr.c: Added func attr misuse error msg
5936 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5938 Fixed bug #787649 by anonymous
5939 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
5940 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
5942 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5944 Fixed numerous bitfield problems.

5952 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
5953 * support/regression/tests/bitfields.c: tests added
5955 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5957 Made the constant following the "interrupt" keyword optional. If
5958 omitted, the function will not automatically be given an entry
5959 in the interrupt vector table (similar to #pragma NOIV, but
5960 less syntacticly kludgy). The interrupt number is also now
5961 range checked. Also fixed a bug in the high order bit example

6488 added --disable-pic16-port
6489 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6490 * src/SDCCmain.c: linkOptions is changed to set *,
6491 added if/endif conditional macros to remove options help
6492 messages from optionsTable when a port is not configured, added
6493 support for the PIc16 port in the ports table, when executing
6494 the compiler with no port specified on command line, a default
6495 port is selected with the new macro DEFAULT_PORT which is
6496 defined in port.h, in setDefaultOptions() linkOptions is removed
6497 from initialization assignment, since now it is a set,
6498 parseCmdLine uses setParseWithComma for linkOptions, in
6499 linkEdit() linkOptions are accessed with new function indexSet()
6500 which returns the i'th item of a set variable. See SDCCset.c, in
6501 linkEdit() when calling buildCmdLine(), added linkOptions as
6502 last argument. Now users can pass arguments to gplink via the
6503 -Wl option, main() uses pic16glue() to glue up pic16 programs

6515 * src/pic16/glue.c: commented out some error producing lines
6516 * src/pic16/main.c: __config directives are commented out to stop
6517 gpasm complaining and test the linkage with gplink, _linkCmd and
6518 _asmCmd changed to be more gplink and gpasm friendly
6519 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6520 produced an error when parsed, peep rule 12 is added to utilize
6521 movff, but it is commented out since the pCode does not support
6522 yet a command with 2 address arguments

7561 * src/SDCCicode.c: fixed array add
7563 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7564 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7565 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7567 2003-01-04 <johan AT balder>
7569 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7571 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7572 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7574 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7575 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7581 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7582 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7584 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7585 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7587 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7589 * in \sdcc\as\mcs51\ changed these files in order to create an
7590 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7591 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7592 following files to include the previous two files: aslink.dsp,
7593 Makefile.aslink, Makefile.bcc, and Makefile.in.
7595 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7596 .adb instead of .cdb
7598 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7600 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7601 value from option --iram-size.
7603 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7605 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7608 2002-09-18 <wiml AT hhhh.org>
7610 * SDCClrange.h: exposed setFromRange() and setToRange()
7611 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7612 packRegsForAccUse() (bug 542397)
7613 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7614 multiple times and emitting the fetch operations more than once
7615 added aopGetUsesAcc() function to allow binary operators to
7616 fetch their operands in the correct order; made genMinus() emit
7617 compact code for X = LITERAL - Y
7619 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7620 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7621 sprintf() in line 1267.
7623 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7624 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7627 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7628 Changes to aslink (All the changes are marked with 'JCF'):
7630 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7633 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7634 area BSEG. Also moves, if possible, the DATA area down into the internal
7635 ram so more space is available.
7637 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7640 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7641 not bytes. Function summary() which creates a memory usage summary
7642 file with extension .mem. Reports of overlaping stack and small stack
7643 size. If the space for the stack is less than 16 bytes aslink trows a
7646 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7647 the 8051. Option 'y' for memory summary output file.
7649 Changes to sdcc (All the changes are marked with 'JCF'):
7651 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7653 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7654 overlaying area for it (uses RegBankUsed[4]).
7656 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7657 bank zero as used by default. By default aslink locates the stack
7658 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7659 the creation of the .mem file. Delegates the allocation of data area
7660 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7661 the begining of the stack area to aslink.
7663 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7664 glue() in SDCCglue.c creates an area for it.
7666 2002-09-03 Borut Razem <borut.razem AT siol.net>
7667 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7668 sdcc/src/pic/glue.c:
7669 introduced atexit() handler for teporay files removal in case of
7670 errors, assertions, ...
7672 2002-08-29 Borut Razem <borut.razem AT siol.net>
7673 * sdcc/support/cpp2/auto-host_vc_in.h:
7674 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7675 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7676 Maybe there is a similar problem with BORLANDC? It should be checked!
7678 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7679 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7680 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7681 was not executed, and the compiler (cl) launched a warning:
7682 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7684 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7685 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7687 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7688 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7690 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7691 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7692 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7693 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7694 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7695 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7696 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7697 - added Release configuration in VS projects
7698 - review of compiler an linker options
7699 - VC .exe files are generated in bin_vc directory, not to interfere
7700 with binaries generated from other projects (cygwin, mingw, bcc ...)
7702 * sdcc/src/yacc.dsp: added
7704 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7705 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7706 and insert the version number definitions from .version
7708 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7710 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7711 added - genarate auto-host.h using auto-host_vc_in.h as template
7714 removed from CVS, generated automatically
7716 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7717 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7719 2002-08-11 Borut Razem <borut.razem AT siol.net>
7720 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7722 2002-08-10 Borut Razem <borut.razem AT siol.net>
7723 * src/SDCCmain.c (main):
7724 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7725 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7726 The consequence was that some temporary files were not removed.
7729 unification of code in functions tempfilename() and tempfile():
7730 function tempnam() is defined in Visual Studio 6.0 and .NET
7732 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7734 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7735 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7736 - removed compiler command line option /WX: Treats all warnings as errors
7737 - update a list of source files, included into the project
7739 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7740 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7741 changed project type to Generic Project so that can be correcly converted to VS.NET project
7743 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7745 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7747 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7749 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7750 added return 0 statements after assert() to make compiler happy
7752 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7753 added newline in the def file to keep MSC compiler satisfied
7755 * sdcc/src/z80/gen.c:
7756 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7757 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7758 - solved MSC error in function aopDump()
7760 * sdcc_vc.h: define PREFIX as "\\sdcc"
7762 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7763 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7765 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7766 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7767 - Rewrote the register banking algorithm.
7768 - Added pCode live-range analysis to registers (for now, only non-used and
7769 singly-used registers optimized away)
7771 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7773 * 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.
7775 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7776 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

7798 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7800 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7802 2002-03-28 Johan Knol <johan AT balder>
7804 * src/SDCCval.c: fixed bug #532436
7806 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7808 Added "char *Processor" field to the port structure.
7811 Added -p option. Allows port dependent processor to be specified.
7814 Initialized the new field char *Processor field to NULL in all ports
7817 Compiler generated registers for interrupt context saving
7818 were not getting allocated.
7820 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7823 Fixed left shift. Will promote the left side of a left shift
7824 if a) left shifting more than size of operand or b) when assigned
7825 to something size > size of left side
7827 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7829 tons of changes. Register allocation has been
7830 rewritten. Added customization for the various PICs. Flow
7831 analysis is restructured. ...
7837 Added. device.c is a PIC port hack to accomodate variations
7840 2002-03-13 Michael Hope <michaelh AT vroom>
7842 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7844 2002-03-04 johanknol <johanknol AT manik>
7846 * /src/SDCCval.c: fixed
7848 const unsigned char arr[][2] = { { 0, 1 } };
7849 t18.c:1: error: Initializer element is not constant
7851 2002-03-04 bela <bela AT manik>
7853 * /device/include/mcs51reg.h:
7854 ds89c420 register definition update
7856 2002-03-03 <johan AT FRIJA>
7858 * support/Util/SDCCerr.c: did something, but don't no why anymore
7860 * support/regression/tests/bug-524691.c: made it a little less shy
