450 * src/SDCCdflow.c (computeDataFlow),
452 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
454 * src/SDCCcflow.c (*),
456 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
457 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
458 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
459 immedDom() returning wrong block; probably fixes bug #1160833)
461 2005-03-20 Borut Razem <borut.razem AT siol.net>
463 * support/scripts/inc2h.pl: WIN32 port
465 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

472 * device/lib/abs.c: added
473 * device/lib/labs.c: added
474 * device/include/stdlib.h: added abs() and labs() prototypes
475 * device/lib/libsdcc.lib: added abs and labs
476 * device/include/float.h,
477 * device/lib/_fsmul.c,
478 * device/lib/printf_fast.c,
479 * device/lib/printf_tiny.c: updated comments
481 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
483 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
486 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
488 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
489 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
491 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
493 * device/lib/printf_large.c: removed inline assembly for portability and
494 readability. Use printf_fast if speed or size are more important.
495 * src/pic16/gen.c: removed conditions around use of DEBUGpc
496 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
498 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
500 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
501 prevent compiler warning
503 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
505 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
506 moved to level 0 and declared as static. Also they are explicit
507 placed in access bank. This was necessery because some times they
508 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
509 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
510 optimizations. Currently only compare to unsigned char is implemented,
511 * src/pic16/gen.c: added fReturnIdx array,
512 * (struct resolvedIfx) is moved to gen.h and made public,
513 * (struct _G): added sregsAlloc and sregsAllocSet fields,
514 * (aopForSym): added an optimization to directly store in stack of
515 the operand of a SEND iCode,
516 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
517 but as registers instead (AOP_REG) using the fReturnIdx array,
518 * (pic16_freeAsmop): remove the freed register from the
520 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
522 * (pic16_popGetTempRegCond): changed function prototype, now
523 function takes also a bitVector argument v which holds the current
524 set of registers that are allocated for stack access by aopForSym,
525 registers allocated in aopForSym for accessing stack symbols are not
526 any more part of the functions usedRegs field,
527 * (genCall): some times aopOp is called for a stack variable to be
528 send, aopForSym might perform the push, if this is true make sure
529 that genCall doesn't push the variable twice by testing _G.resDirect,
530 * (genFunction): changed testing for unspecified interrupt number
531 from 256 to INTNO_UNSPEC,
532 * modified selection scheme of frame pointer generation. Previously
533 if function did use local registers a frame pointer was generated,
534 now a frame pointer is generated only if function has arguments
535 (that need PLUSW2 register access), or has stack arguments, or the
536 compiler is not instructed to omit the frame pointer,
537 * (genEndFunction): before restoring local registers that were saved
538 in the function preamble, also restore the registers that *might*
539 have been allocated for stack access,
540 * (genRet): removed some old comments,
541 * (genCmp, the active (RN's) version): added a call to the
542 pic16_genCmp_special function to perform the compare with a more
543 robust and optimized way,
544 * (genInline): a feature has been added in inline code generation,
545 which allows a wildcard variable substitution when writing inline
546 assembly. Code is incomplete and experimental therefore undocumented,
547 * (genCast): changed order of aopOp for result and right to allow
548 aopForSym to directly load the result if possible,
549 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
550 perform an optimized compare on some selected special occasions,
551 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
552 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
553 generate an IVT any more,
554 * src/pic16/main.c (pic16_optionsTable): added command line option
556 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
557 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
559 * src/pic16/NOTES: Raphael Neider added in list of active developers
560 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
561 jumptable_end to prevent bug #,
562 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
563 inCond and outCond fields,
564 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
565 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
566 turn off register spilling,
567 * (packRegsForOneUse): synced with other ports' versions although it
568 is not used currently,
569 * (pic16_packRegisters): added an optimization while reading
570 structure bitfields, some registers may be saved (malloc code is
571 decreased by 80 bytes)
573 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
575 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
576 left is a bitfield, if yes, then don't optimize assignment. Perhaps
577 this can be optimized more?
579 2005-03-10 Raphael Neider <rneider AT web.de>
581 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
582 genNearPointerGet): (hopefully) fixed access to bitfields via
583 pointers (p->bitN = x; and x = p->bitN; failed)

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

1218 generated for switch statements. For now you need to set the
1219 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1220 Now 4 algorithms for mcs51 jumptable generation are used:
1221 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1255 * added libc directory. The current version of LibC contains string
1256 functions, ctype functions and macros and some functions of the
1257 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1258 be extensively tested in the future. Standard disclaimer here.
1259 Library is not automatically build yet. But one can build it by

1271 * (pic16_storeForReturn): optimized return of 0,
1272 * (genCmp): experimental code for new genCmp which uses PIC18's
1273 special compare&skip instructions. Initial tests fail some times
1274 with variables grater than 1 byte in size, so new code is disabled,
1275 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1277 * (genCast): began a fix to optimize the casting of a bit to another
1278 bit, now assigning a bitfield to another bitfield will fail, sorry,

1292 registers when it shouldn't,
1293 * src/pic16/ralloc.c (allocReg): add preliminary support for
1294 supporting a limited set of temporary registers,
1296 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4303 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4304 loaded with the linker search paths (-L arguments) and the libraries
4305 to be linked with the current source (-l arguments). Changes
4306 currently will affect only the pic16 port.
4307 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4308 include path the port specific paths and port specific libraries,
4309 * gplink command now contains the $3 argument,
4310 * src/pic16/device.h,
4311 * src/pic16/device.c,: structure PIC_device is made public and

4327 Documenting changes from previous commits.
4328 * configure.in (version 1.56),
4329 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4330 when generating output files to configure the pic16 library,
4331 but now I've commented it out, since gputils aren't installed in the
4332 SF compile farm, so library won't compile
4334 * device/lib/Makefile.in (version 1.56): initially I've added in
4335 target 'all' the prerequestive 'model-pic16' so it compiled the
4336 pic16 library, but now I've commented it out for the same reasons
4338 * added targets 'model-pic16' and 'objects-pic16' to compile the
4340 * added target 'port-specific-objects-pic16' to handle the
4341 generated libraries and copy them into the build/ directory
4342 * added target 'clean-intermediate-pic16' to clean intermediate
4343 files into pic16 directory
4344 * in target 'installdirs' added line to create directory pic16 in

4348 added lines to copy all header files to installation path,
4349 * in target 'installdirs' added line create directory for pic16
4350 headers in the installation path

4366 option so that it actually works. Made it specific to the z80, since
4367 the gbz80 doesn't have these kinds of I/O ports.
4369 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4371 * device/include/z180.h,

4395 via literal number. The symbol is placed in the corresponding
4396 position of the data ram
4397 * (pic16_dump_section): relocatable and absolute uninitialized
4398 data are now emitted in sorted order to reduce section naming,
4399 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4400 weren't marked as being in the access bank,
4402 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4404 Added portion of GNU PIC Library under the directory
4405 device/include/pic16 and device/lib/pic16. These files
4406 contain the declarations of SFRs for the PIC18Fxx2 devices.
4407 The directory is initialized via configure from toplevel.

4437 all over. Telling LaTeX to be less strict with word spacing
4438 to better keep the right margin. Changed some notes about
4439 maintainance of the ports in section 3.2.1 - is it OK like this?
4441 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4478 UPPER for immediate operands,
4479 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4481 * src/pic16/peeph.def: all peepholes with movff are commented out,
4482 because there is a problem in the pcode peep optimizer,
4483 * src/pic16/ralloc.c: the register allocator can now reuse local
4484 function symbols for another function. This saves register usage.

4593 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4595 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4596 (default behaviour).
4598 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4600 A python script to validate compiler diagnostic messages. It can be
4601 used to verify that sdcc complains about bad c source code and
4602 gives a good location of the error.
4603 * support/valdiag/Makefile,
4604 * support/valdiag/valdiag.py,
4605 * support/valdiag/tests/*

4624 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4626 * sdcc.spec: updated
4627 * device/include/Makefile.in: don't install CVS directories
4628 * device/lib/Makefile.in: added removal of CVS directories after install
4629 * doc/Makefile: fixed install, added local_icons
4630 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

4635 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4637 PIC16 port related changes:
4638 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4639 added variable stackPos,
4641 * gen.c: genCall, assignResultValue: added support for
4642 pushing/retrieving function parameters to/from stack,
4643 genFunction,genEndFunction: setup stack frame for the
4645 genAddrOf: will be changed according to bug 863624
4647 * added files genutils.c and genutils.h which contain gen*
4648 debugged and optimised functions extracted from gen.c
4650 * glue.c: added variable 'externs' which holds extern symbols,
4651 pic16emitRegularMap: is modified to properly handle relocatable
4652 symbols under the new scheme,
4653 pic16createInterruptVect: is modified
4654 pic16printPublics: is modified to emit 'global' assembler directives,
4655 added pic16_printExterns to print extern symbols,
4656 pic16glue: initializes stack/frame pointer in the beginning of
4657 the assembly output. Temporary hack, will be corrected later,
4658 because gplink yet does not support stack and SDCC does not
4659 yet support a type of crt0.o object to create the final binary.
4661 * Removed many lines that contain 8051 legacy code.
4662 * The code is finally placed under a 'code' directive.
4663 * Added port specific options.
4665 * _process_pragma: simplified since now we do not need *special*
4666 include file to define SFR registers. But a separate header
4667 will be needed. This will be developed later.
4668 * _pic16_parseOptions: added, parses port specific options:
4669 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4670 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4671 --preplace-udata-with=
4673 * _pic16_setDefaultOptions: modified to initialize section names,
4674 but hack is temporarly out of order since it needs improvement.
4675 * _pic16_genAssemblerPreamble: configuration words are emitted by
4676 their address instead of their name. This part is incomplete and
4677 supports only the 18Fxx2 devices. Other devices will emit an error
4678 during assembly since they do not contain the same set of config
4680 * _pic16_genIVT: is modified,
4682 * pcode.c: added definitions for some hardware registers that are needed
4684 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4685 All PCI entries are updated. Now LFSR is supported.
4686 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4687 * added pic16_newpCodeOpLit2 to support instructions with
4688 two literal arguments
4689 * pic16_pCode2str: corrected code that emits assembler instructions
4690 with two literal operands and those that have an access bit modifier
4691 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4692 this fixes a bug which caused some labels to be lost, when an
4693 assembler directive was added, i.e. banksel,
4694 * pic16_FixRegisterBanking: improved logic that causes the insertion
4696 * InlineFunction: functions that are called once, are not any more
4697 inlined. This can be a port option in the future,
4699 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4701 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4702 hold the corresponding uninitialized symbols,
4703 * pic16_allocProcessorRegister: registers have explicit marked the
4705 * pic16_allocInternalRegister: registers are explicit marked as
4707 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4708 processing list, so bit registers were lost,
4711 * ralloc.h: added field 'accessBank' and original symbol operand
4712 in register definition,
4713 * removed the field isMapped from register definition,
4715 ** Several functions have been removed from various sources:
4716 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4717 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4718 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4719 pic16_assignRelocatableRegisters
4721 ** others have been introduced:
4722 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4723 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4725 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4727 * support/scripts/inc2h.pl: changed definition of BIT_AT
4728 to emit 'sbit at' instead of 'bit at'. This was a request.
4730 PIC16 port related preliminary changes:
4731 * gen.c: prefixed function popRegFromString with
4732 pic16_ and all references to it corrected
4733 * pcode.c: all pic16_pc_* hardware registers prefixed
4734 with underscore (_),
4735 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4736 * ralloc.c: newReg(): when register is REG_SFR then
4737 set address to rIdx,
4738 pic16_allocProcessorRegister(): marks register wasUsed=0
4739 pic16_writeUsedRegs(): added a call to assign processor
4740 registers via pic16_assignFixedRegisters
4742 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4744 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4745 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4746 variables in unused register banks. Also the SSEG is placed
4747 wherever there is enough space for it, and IDATA can be anywhere
4748 in internal RAM. For now compile using -Wl-Y[stack_size].
4749 The mem file is different for this option as well, since it
4750 makes no sense of talking about DSEG lenght.
4752 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4754 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4755 in certain cases, e.g. when ROM assignment, patch provided
4756 from Albert den Haan.
4758 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4901 * src/mcs51/peephole.def,
4902 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4903 (allows non-interrupt and interrupt code to safely compete for a resource

5643 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5644 support for standard C idiom of memory mapped variables; for
5645 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5646 to xdata int at 0x1234 tempvar = 1.
5647 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5648 provided by Akiya ISHIDA

5664 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5666 Fixed bug #621531 (const & volatile confusion in the type chain).
5667 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5733 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
5734 pcoderegs.h, ralloc.c, ralloc.h
5735 * main.c: added top header and GPL license notice

5759 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5760 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5761 fetching of the pointer
5762 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5763 copied from genNearPointerSet()
5764 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5765 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5766 If they pop r0/r1 they must be called in the opposite order than aopOp().
5767 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5768 (resp. --stack-auto), prepared for --xstack

5777 these ports have their own __sdcc_external_start()
5779 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5781 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5782 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5783 type for bits was changed. It resulted in bit variables becoming
5784 global, which is not permitted in PIC 14 assembly output.
5786 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5788 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5799 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5801 A few small changes that speed up the peephole optimizer.
5805 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5807 Try to make the peephole optimizer smarter by maintaining
5808 an association between the assembly source code and the
5809 iCodes that originated them. Put this information to use
5810 with a new peephole rule condition "notVolatile" so that
5811 the rules can be aggressive yet still safe.
5816 * src/mcs51/peeph.def
5818 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5822 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5823 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5824 if the left or right operand symbols have the accuse flag set.
5826 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5828 Changed the type of the result of the ! (NOT) operator to char;
5829 previously it returned the same type as the source. This allows
5830 us to eliminate all the genFloatNot functions (all of its target
5831 implementations were very buggy) since !float can use the same
5834 * src/SDCCicode.c (ast2iCode): ! returns char
5835 * src/mcs51/gen.c (genNot, genNotFloat),
5836 * src/ds390/gen.c (genNot, genNotFloat),
5837 * src/z80/gen.c (genNot, genNotFloat),
5838 * src/pic/gen.c (genNot, genNotFloat),
5839 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5841 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5843 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5844 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5845 during interrupts. Ensure WSAVE is located at a shared bank address.
5846 2. Fixed page selection in some places
5847 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5848 the registers name strings.
5849 4. Fixed "signed / unsigned compare" compiler warnings.
5850 5. The PIC port manages its own allocation of the general purpose
5851 registers, but makes no attempt to reuse them. As a result when
5852 compiling it soon runs out of general purpose registers. Some
5853 additional code was added to the files pcode.c and device.c to walk
5854 through the function call tree and rename the registers so that they
5864 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5865 genPlus() & genMinus() when the result is the same as left or right
5867 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5871 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5873 Made bitfield a distinct type from bit so that bitfields
5874 convert as per ANSI C and bits retain their traditional
5875 boolean style behaviour. Implemented bitfield support in
5883 * src/ds390/gen.c: bit v bitfield split
5884 * src/z80/gen.c: New support for bitfields
5885 * support/regression/tests/bitfields.c: reenabled z80,
5888 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5890 Rules 246.x, 247.x relate to bitfields, the others speed up
5891 access to xdata mapped I/O devices.
5893 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5895 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5897 Cleaned up genPackBits and genUnpackBits and added two helper
5898 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5899 for literal assignments in genPackBits (thanks to Frieder for
5905 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5907 Fixed bug #748310 (pointer to function type mishandled when the
5908 function name is omitted). Also fixed a SIGSEGV when a function
5909 attribute (reentrant, etc) is used on a non-function or on a
5910 function but misplaced before the parameter list.
5912 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5914 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5915 * support/Util/SDCCerr.h,
5916 * support/Util/SDCCerr.c: Added func attr misuse error msg
5918 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5920 Fixed bug #787649 by anonymous
5921 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
5922 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
5924 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5937 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5939 Made the constant following the "interrupt" keyword optional. If
5940 omitted, the function will not automatically be given an entry
5941 in the interrupt vector table (similar to #pragma NOIV, but
5942 less syntacticly kludgy). The interrupt number is also now
5943 range checked. Also fixed a bug in the high order bit example

5951 * support/Util/SDCCerr.h
5954 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5956 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5957 * src/SDCCicode.c (operandOperation): rewritten some ops
5958 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5959 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5961 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5962 be re-activated by defining REDUCE_LITERALS)
5963 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5964 unsigned, but are signed by default
5965 * src/SDCCval.c (constVal): rearranged
5966 * src/SDCCval.c (valMod): preliminary fix
5967 * src/SDCCval.c (valCastLiteral): use TYPE_* types
5968 * support/regression/literalop.c: added, work in progress

6473 added if/endif conditional macros to remove options help
6474 messages from optionsTable when a port is not configured, added
6475 support for the PIc16 port in the ports table, when executing
6476 the compiler with no port specified on command line, a default
6477 port is selected with the new macro DEFAULT_PORT which is
6478 defined in port.h, in setDefaultOptions() linkOptions is removed
6479 from initialization assignment, since now it is a set,
6480 parseCmdLine uses setParseWithComma for linkOptions, in
6481 linkEdit() linkOptions are accessed with new function indexSet()
6482 which returns the i'th item of a set variable. See SDCCset.c, in
6483 linkEdit() when calling buildCmdLine(), added linkOptions as
6484 last argument. Now users can pass arguments to gplink via the
6485 -Wl option, main() uses pic16glue() to glue up pic16 programs

6498 * src/pic16/main.c: __config directives are commented out to stop
6499 gpasm complaining and test the linkage with gplink, _linkCmd and
6500 _asmCmd changed to be more gplink and gpasm friendly
6501 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6502 produced an error when parsed, peep rule 12 is added to utilize
6503 movff, but it is commented out since the pCode does not support
6504 yet a command with 2 address arguments
6506 2003-05-18 <johan AT balder>
6508 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7547 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7549 2003-01-04 <johan AT balder>
7551 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7553 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7566 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7567 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7569 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7571 * in \sdcc\as\mcs51\ changed these files in order to create an
7572 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7573 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7574 following files to include the previous two files: aslink.dsp,
7575 Makefile.aslink, Makefile.bcc, and Makefile.in.
7577 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7578 .adb instead of .cdb
7580 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7582 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7583 value from option --iram-size.
7585 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7587 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7590 2002-09-18 <wiml AT hhhh.org>
7592 * SDCClrange.h: exposed setFromRange() and setToRange()
7593 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7594 packRegsForAccUse() (bug 542397)
7595 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7596 multiple times and emitting the fetch operations more than once
7597 added aopGetUsesAcc() function to allow binary operators to
7598 fetch their operands in the correct order; made genMinus() emit
7599 compact code for X = LITERAL - Y
7601 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7602 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7603 sprintf() in line 1267.
7605 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7606 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7609 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7610 Changes to aslink (All the changes are marked with 'JCF'):
7612 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7615 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7616 area BSEG. Also moves, if possible, the DATA area down into the internal
7617 ram so more space is available.
7619 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7622 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7623 not bytes. Function summary() which creates a memory usage summary
7624 file with extension .mem. Reports of overlaping stack and small stack
7625 size. If the space for the stack is less than 16 bytes aslink trows a
7628 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7629 the 8051. Option 'y' for memory summary output file.
7631 Changes to sdcc (All the changes are marked with 'JCF'):
7633 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7635 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7636 overlaying area for it (uses RegBankUsed[4]).
7638 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7639 bank zero as used by default. By default aslink locates the stack
7640 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7641 the creation of the .mem file. Delegates the allocation of data area
7642 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7643 the begining of the stack area to aslink.
7645 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7646 glue() in SDCCglue.c creates an area for it.
7648 2002-09-03 Borut Razem <borut.razem AT siol.net>
7649 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7650 sdcc/src/pic/glue.c:
7651 introduced atexit() handler for teporay files removal in case of
7652 errors, assertions, ...
7654 2002-08-29 Borut Razem <borut.razem AT siol.net>
7655 * sdcc/support/cpp2/auto-host_vc_in.h:
7656 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7657 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7658 Maybe there is a similar problem with BORLANDC? It should be checked!
7660 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7661 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7662 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7663 was not executed, and the compiler (cl) launched a warning:
7664 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7666 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7667 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7669 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7670 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7672 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7673 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7674 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7675 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7676 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7677 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7678 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7679 - added Release configuration in VS projects
7680 - review of compiler an linker options
7681 - VC .exe files are generated in bin_vc directory, not to interfere
7682 with binaries generated from other projects (cygwin, mingw, bcc ...)
7684 * sdcc/src/yacc.dsp: added
7686 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7687 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7688 and insert the version number definitions from .version
7690 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7692 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7693 added - genarate auto-host.h using auto-host_vc_in.h as template
7696 removed from CVS, generated automatically
7698 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7699 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7701 2002-08-11 Borut Razem <borut.razem AT siol.net>
7702 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7704 2002-08-10 Borut Razem <borut.razem AT siol.net>
7705 * src/SDCCmain.c (main):
7706 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7707 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7708 The consequence was that some temporary files were not removed.
7711 unification of code in functions tempfilename() and tempfile():
7712 function tempnam() is defined in Visual Studio 6.0 and .NET
7714 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7716 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7717 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7718 - removed compiler command line option /WX: Treats all warnings as errors
7719 - update a list of source files, included into the project
7721 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7722 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7723 changed project type to Generic Project so that can be correcly converted to VS.NET project
7725 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7727 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7729 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7731 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7732 added return 0 statements after assert() to make compiler happy
7734 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7735 added newline in the def file to keep MSC compiler satisfied
7737 * sdcc/src/z80/gen.c:
7738 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7739 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7740 - solved MSC error in function aopDump()
7742 * sdcc_vc.h: define PREFIX as "\\sdcc"
7744 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7745 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7747 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7748 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7749 - Rewrote the register banking algorithm.
7750 - Added pCode live-range analysis to registers (for now, only non-used and
7751 singly-used registers optimized away)
7753 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7755 * 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.

7784 2002-03-28 Johan Knol <johan AT balder>
7786 * src/SDCCval.c: fixed bug #532436
7788 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7790 Added "char *Processor" field to the port structure.
7793 Added -p option. Allows port dependent processor to be specified.
7796 Initialized the new field char *Processor field to NULL in all ports
7799 Compiler generated registers for interrupt context saving
7800 were not getting allocated.
7802 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7805 Fixed left shift. Will promote the left side of a left shift
7806 if a) left shifting more than size of operand or b) when assigned
7807 to something size > size of left side
7809 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7811 tons of changes. Register allocation has been
7812 rewritten. Added customization for the various PICs. Flow
7813 analysis is restructured. ...
7819 Added. device.c is a PIC port hack to accomodate variations
7822 2002-03-13 Michael Hope <michaelh AT vroom>
7824 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7826 2002-03-04 johanknol <johanknol AT manik>
