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

467 2005-03-20 Borut Razem <borut.razem AT siol.net>
469 * support/scripts/inc2h.pl: WIN32 port
471 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

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

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

1224 generated for switch statements. For now you need to set the
1225 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1226 Now 4 algorithms for mcs51 jumptable generation are used:
1227 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1261 * added libc directory. The current version of LibC contains string
1262 functions, ctype functions and macros and some functions of the
1263 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1264 be extensively tested in the future. Standard disclaimer here.

1277 * (pic16_storeForReturn): optimized return of 0,
1278 * (genCmp): experimental code for new genCmp which uses PIC18's
1279 special compare&skip instructions. Initial tests fail some times
1280 with variables grater than 1 byte in size, so new code is disabled,
1281 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1283 * (genCast): began a fix to optimize the casting of a bit to another
1284 bit, now assigning a bitfield to another bitfield will fail, sorry,

1299 * src/pic16/ralloc.c (allocReg): add preliminary support for
1300 supporting a limited set of temporary registers,
1302 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1326 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1328 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4307 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4309 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4310 loaded with the linker search paths (-L arguments) and the libraries
4311 to be linked with the current source (-l arguments). Changes
4312 currently will affect only the pic16 port.
4313 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4314 include path the port specific paths and port specific libraries,
4315 * gplink command now contains the $3 argument,
4316 * src/pic16/device.h,
4317 * src/pic16/device.c,: structure PIC_device is made public and
4318 renamed to PIC16_device, the same for variable Pics which is renamed

4333 Documenting changes from previous commits.
4334 * configure.in (version 1.56),
4335 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4336 when generating output files to configure the pic16 library,
4337 but now I've commented it out, since gputils aren't installed in the
4338 SF compile farm, so library won't compile
4340 * device/lib/Makefile.in (version 1.56): initially I've added in
4341 target 'all' the prerequestive 'model-pic16' so it compiled the
4342 pic16 library, but now I've commented it out for the same reasons
4344 * added targets 'model-pic16' and 'objects-pic16' to compile the
4346 * added target 'port-specific-objects-pic16' to handle the
4347 generated libraries and copy them into the build/ directory
4348 * added target 'clean-intermediate-pic16' to clean intermediate
4349 files into pic16 directory
4350 * in target 'installdirs' added line to create directory pic16 in
4351 the installation path
4353 * device/include/Makefile.in (version 1.11): in target 'install'
4354 added lines to copy all header files to installation path,
4355 * in target 'installdirs' added line create directory for pic16
4356 headers in the installation path

4372 option so that it actually works. Made it specific to the z80, since
4373 the gbz80 doesn't have these kinds of I/O ports.
4375 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4377 * device/include/z180.h,

4401 via literal number. The symbol is placed in the corresponding
4402 position of the data ram
4403 * (pic16_dump_section): relocatable and absolute uninitialized
4404 data are now emitted in sorted order to reduce section naming,
4405 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4406 weren't marked as being in the access bank,
4408 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4410 Added portion of GNU PIC Library under the directory
4411 device/include/pic16 and device/lib/pic16. These files
4412 contain the declarations of SFRs for the PIC18Fxx2 devices.
4413 The directory is initialized via configure from toplevel.
4415 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4443 all over. Telling LaTeX to be less strict with word spacing
4444 to better keep the right margin. Changed some notes about
4445 maintainance of the ports in section 3.2.1 - is it OK like this?
4447 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4449 SDCC source changes:
4450 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4599 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4601 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4602 (default behaviour).
4604 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4606 A python script to validate compiler diagnostic messages. It can be
4607 used to verify that sdcc complains about bad c source code and
4608 gives a good location of the error.
4609 * support/valdiag/Makefile,
4610 * support/valdiag/valdiag.py,

4630 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4632 * sdcc.spec: updated
4633 * device/include/Makefile.in: don't install CVS directories
4634 * device/lib/Makefile.in: added removal of CVS directories after install
4635 * doc/Makefile: fixed install, added local_icons
4636 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

4641 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4643 PIC16 port related changes:
4644 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4645 added variable stackPos,
4647 * gen.c: genCall, assignResultValue: added support for
4648 pushing/retrieving function parameters to/from stack,
4649 genFunction,genEndFunction: setup stack frame for the
4651 genAddrOf: will be changed according to bug 863624
4653 * added files genutils.c and genutils.h which contain gen*
4654 debugged and optimised functions extracted from gen.c
4656 * glue.c: added variable 'externs' which holds extern symbols,
4657 pic16emitRegularMap: is modified to properly handle relocatable
4658 symbols under the new scheme,
4659 pic16createInterruptVect: is modified
4660 pic16printPublics: is modified to emit 'global' assembler directives,
4661 added pic16_printExterns to print extern symbols,
4662 pic16glue: initializes stack/frame pointer in the beginning of
4663 the assembly output. Temporary hack, will be corrected later,
4664 because gplink yet does not support stack and SDCC does not
4665 yet support a type of crt0.o object to create the final binary.
4667 * Removed many lines that contain 8051 legacy code.
4668 * The code is finally placed under a 'code' directive.
4669 * Added port specific options.
4671 * _process_pragma: simplified since now we do not need *special*
4672 include file to define SFR registers. But a separate header
4673 will be needed. This will be developed later.
4674 * _pic16_parseOptions: added, parses port specific options:
4675 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4676 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4677 --preplace-udata-with=
4679 * _pic16_setDefaultOptions: modified to initialize section names,
4680 but hack is temporarly out of order since it needs improvement.
4681 * _pic16_genAssemblerPreamble: configuration words are emitted by
4682 their address instead of their name. This part is incomplete and
4683 supports only the 18Fxx2 devices. Other devices will emit an error
4684 during assembly since they do not contain the same set of config
4686 * _pic16_genIVT: is modified,
4688 * pcode.c: added definitions for some hardware registers that are needed
4690 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4691 All PCI entries are updated. Now LFSR is supported.
4692 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4693 * added pic16_newpCodeOpLit2 to support instructions with
4694 two literal arguments
4695 * pic16_pCode2str: corrected code that emits assembler instructions
4696 with two literal operands and those that have an access bit modifier
4697 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4698 this fixes a bug which caused some labels to be lost, when an
4699 assembler directive was added, i.e. banksel,
4700 * pic16_FixRegisterBanking: improved logic that causes the insertion
4702 * InlineFunction: functions that are called once, are not any more
4703 inlined. This can be a port option in the future,
4705 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4707 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4708 hold the corresponding uninitialized symbols,
4709 * pic16_allocProcessorRegister: registers have explicit marked the
4711 * pic16_allocInternalRegister: registers are explicit marked as
4713 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4714 processing list, so bit registers were lost,
4717 * ralloc.h: added field 'accessBank' and original symbol operand
4718 in register definition,
4719 * removed the field isMapped from register definition,
4721 ** Several functions have been removed from various sources:
4722 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4723 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4724 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4725 pic16_assignRelocatableRegisters
4727 ** others have been introduced:
4728 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4729 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4731 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4733 * support/scripts/inc2h.pl: changed definition of BIT_AT
4734 to emit 'sbit at' instead of 'bit at'. This was a request.
4736 PIC16 port related preliminary changes:
4737 * gen.c: prefixed function popRegFromString with
4738 pic16_ and all references to it corrected
4739 * pcode.c: all pic16_pc_* hardware registers prefixed
4740 with underscore (_),
4741 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4742 * ralloc.c: newReg(): when register is REG_SFR then
4743 set address to rIdx,
4744 pic16_allocProcessorRegister(): marks register wasUsed=0
4745 pic16_writeUsedRegs(): added a call to assign processor
4746 registers via pic16_assignFixedRegisters
4748 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4750 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4751 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4752 variables in unused register banks. Also the SSEG is placed
4753 wherever there is enough space for it, and IDATA can be anywhere
4754 in internal RAM. For now compile using -Wl-Y[stack_size].
4755 The mem file is different for this option as well, since it
4756 makes no sense of talking about DSEG lenght.
4758 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4760 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4761 in certain cases, e.g. when ROM assignment, patch provided
4762 from Albert den Haan.
4764 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4907 * src/mcs51/peephole.def,
4908 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4909 (allows non-interrupt and interrupt code to safely compete for a resource

5649 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5650 support for standard C idiom of memory mapped variables; for
5651 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5652 to xdata int at 0x1234 tempvar = 1.
5653 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5654 provided by Akiya ISHIDA

5670 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5672 Fixed bug #621531 (const & volatile confusion in the type chain).
5673 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5765 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5766 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5767 fetching of the pointer
5768 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5769 copied from genNearPointerSet()
5770 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5771 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5772 If they pop r0/r1 they must be called in the opposite order than aopOp().
5773 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5774 (resp. --stack-auto), prepared for --xstack

5783 these ports have their own __sdcc_external_start()
5785 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5787 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5788 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5789 type for bits was changed. It resulted in bit variables becoming
5790 global, which is not permitted in PIC 14 assembly output.
5792 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5794 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5807 A few small changes that speed up the peephole optimizer.
5811 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5813 Try to make the peephole optimizer smarter by maintaining
5814 an association between the assembly source code and the
5815 iCodes that originated them. Put this information to use
5816 with a new peephole rule condition "notVolatile" so that
5817 the rules can be aggressive yet still safe.
5822 * src/mcs51/peeph.def
5824 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5828 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5829 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5830 if the left or right operand symbols have the accuse flag set.
5832 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5834 Changed the type of the result of the ! (NOT) operator to char;
5835 previously it returned the same type as the source. This allows
5836 us to eliminate all the genFloatNot functions (all of its target
5837 implementations were very buggy) since !float can use the same
5840 * src/SDCCicode.c (ast2iCode): ! returns char

5842 * src/ds390/gen.c (genNot, genNotFloat),
5843 * src/z80/gen.c (genNot, genNotFloat),
5844 * src/pic/gen.c (genNot, genNotFloat),

5847 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5849 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5850 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5851 during interrupts. Ensure WSAVE is located at a shared bank address.
5852 2. Fixed page selection in some places
5853 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5854 the registers name strings.
5855 4. Fixed "signed / unsigned compare" compiler warnings.
5856 5. The PIC port manages its own allocation of the general purpose
5857 registers, but makes no attempt to reuse them. As a result when
5858 compiling it soon runs out of general purpose registers. Some
5859 additional code was added to the files pcode.c and device.c to walk
5860 through the function call tree and rename the registers so that they
5870 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5871 genPlus() & genMinus() when the result is the same as left or right
5873 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5877 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5879 Made bitfield a distinct type from bit so that bitfields
5880 convert as per ANSI C and bits retain their traditional
5881 boolean style behaviour. Implemented bitfield support in
5889 * src/ds390/gen.c: bit v bitfield split
5890 * src/z80/gen.c: New support for bitfields
5891 * support/regression/tests/bitfields.c: reenabled z80,
5894 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5896 Rules 246.x, 247.x relate to bitfields, the others speed up
5897 access to xdata mapped I/O devices.
5899 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5901 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5903 Cleaned up genPackBits and genUnpackBits and added two helper
5904 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5905 for literal assignments in genPackBits (thanks to Frieder for
5911 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5913 Fixed bug #748310 (pointer to function type mishandled when the
5914 function name is omitted). Also fixed a SIGSEGV when a function
5915 attribute (reentrant, etc) is used on a non-function or on a
5916 function but misplaced before the parameter list.
5918 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5920 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5921 * support/Util/SDCCerr.h,
5922 * support/Util/SDCCerr.c: Added func attr misuse error msg
5924 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5926 Fixed bug #787649 by anonymous
5927 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
5928 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
5930 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5943 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5945 Made the constant following the "interrupt" keyword optional. If
5946 omitted, the function will not automatically be given an entry
5947 in the interrupt vector table (similar to #pragma NOIV, but
5948 less syntacticly kludgy). The interrupt number is also now
5949 range checked. Also fixed a bug in the high order bit example

5957 * support/Util/SDCCerr.h
5960 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5962 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5963 * src/SDCCicode.c (operandOperation): rewritten some ops
5964 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5965 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5967 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5968 be re-activated by defining REDUCE_LITERALS)
5969 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5970 unsigned, but are signed by default

6479 added if/endif conditional macros to remove options help
6480 messages from optionsTable when a port is not configured, added
6481 support for the PIc16 port in the ports table, when executing
6482 the compiler with no port specified on command line, a default
6483 port is selected with the new macro DEFAULT_PORT which is
6484 defined in port.h, in setDefaultOptions() linkOptions is removed
6485 from initialization assignment, since now it is a set,
6486 parseCmdLine uses setParseWithComma for linkOptions, in
6487 linkEdit() linkOptions are accessed with new function indexSet()
6488 which returns the i'th item of a set variable. See SDCCset.c, in
6489 linkEdit() when calling buildCmdLine(), added linkOptions as
6490 last argument. Now users can pass arguments to gplink via the
6491 -Wl option, main() uses pic16glue() to glue up pic16 programs

6504 * src/pic16/main.c: __config directives are commented out to stop
6505 gpasm complaining and test the linkage with gplink, _linkCmd and
6506 _asmCmd changed to be more gplink and gpasm friendly
6507 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6508 produced an error when parsed, peep rule 12 is added to utilize
6509 movff, but it is commented out since the pCode does not support
6510 yet a command with 2 address arguments
6512 2003-05-18 <johan AT balder>
6514 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7555 2003-01-04 <johan AT balder>
7557 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7559 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7572 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7573 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7575 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7577 * in \sdcc\as\mcs51\ changed these files in order to create an
7578 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7579 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7580 following files to include the previous two files: aslink.dsp,
7581 Makefile.aslink, Makefile.bcc, and Makefile.in.
7583 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7584 .adb instead of .cdb
7586 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7588 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7589 value from option --iram-size.
7591 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7593 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7596 2002-09-18 <wiml AT hhhh.org>
7598 * SDCClrange.h: exposed setFromRange() and setToRange()
7599 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7600 packRegsForAccUse() (bug 542397)
7601 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7602 multiple times and emitting the fetch operations more than once
7603 added aopGetUsesAcc() function to allow binary operators to
7604 fetch their operands in the correct order; made genMinus() emit
7605 compact code for X = LITERAL - Y
7607 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7608 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7609 sprintf() in line 1267.
7611 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7612 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7615 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7616 Changes to aslink (All the changes are marked with 'JCF'):
7618 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7621 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7622 area BSEG. Also moves, if possible, the DATA area down into the internal
7623 ram so more space is available.
7625 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7628 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7629 not bytes. Function summary() which creates a memory usage summary
7630 file with extension .mem. Reports of overlaping stack and small stack
7631 size. If the space for the stack is less than 16 bytes aslink trows a
7634 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7635 the 8051. Option 'y' for memory summary output file.
7637 Changes to sdcc (All the changes are marked with 'JCF'):
7639 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7641 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7642 overlaying area for it (uses RegBankUsed[4]).
7644 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7645 bank zero as used by default. By default aslink locates the stack
7646 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7647 the creation of the .mem file. Delegates the allocation of data area
7648 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7649 the begining of the stack area to aslink.
7651 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7652 glue() in SDCCglue.c creates an area for it.
7654 2002-09-03 Borut Razem <borut.razem AT siol.net>
7655 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7656 sdcc/src/pic/glue.c:
7657 introduced atexit() handler for teporay files removal in case of
7658 errors, assertions, ...
7660 2002-08-29 Borut Razem <borut.razem AT siol.net>
7661 * sdcc/support/cpp2/auto-host_vc_in.h:
7662 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7663 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7664 Maybe there is a similar problem with BORLANDC? It should be checked!
7666 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7667 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7668 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7669 was not executed, and the compiler (cl) launched a warning:
7670 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7672 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7673 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7675 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7676 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7678 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7679 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7680 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7681 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7682 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7683 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7684 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7685 - added Release configuration in VS projects
7686 - review of compiler an linker options
7687 - VC .exe files are generated in bin_vc directory, not to interfere
7688 with binaries generated from other projects (cygwin, mingw, bcc ...)
7690 * sdcc/src/yacc.dsp: added
7692 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7693 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7694 and insert the version number definitions from .version
7696 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7698 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7699 added - genarate auto-host.h using auto-host_vc_in.h as template
7702 removed from CVS, generated automatically
7704 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7705 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7707 2002-08-11 Borut Razem <borut.razem AT siol.net>
7708 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7710 2002-08-10 Borut Razem <borut.razem AT siol.net>
7711 * src/SDCCmain.c (main):
7712 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7713 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7714 The consequence was that some temporary files were not removed.
7717 unification of code in functions tempfilename() and tempfile():
7718 function tempnam() is defined in Visual Studio 6.0 and .NET
7720 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
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 - removed compiler command line option /WX: Treats all warnings as errors
7725 - update a list of source files, included into the project
7727 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7728 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7729 changed project type to Generic Project so that can be correcly converted to VS.NET project
7731 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7733 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7735 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7737 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7738 added return 0 statements after assert() to make compiler happy
7740 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7741 added newline in the def file to keep MSC compiler satisfied
7743 * sdcc/src/z80/gen.c:
7744 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7745 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7746 - solved MSC error in function aopDump()
7748 * sdcc_vc.h: define PREFIX as "\\sdcc"
7750 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7751 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7790 2002-03-28 Johan Knol <johan AT balder>
7792 * src/SDCCval.c: fixed bug #532436
7794 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7796 Added "char *Processor" field to the port structure.
7799 Added -p option. Allows port dependent processor to be specified.
7802 Initialized the new field char *Processor field to NULL in all ports
7805 Compiler generated registers for interrupt context saving
7806 were not getting allocated.
7808 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7811 Fixed left shift. Will promote the left side of a left shift
7812 if a) left shifting more than size of operand or b) when assigned
7813 to something size > size of left side
7815 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7817 tons of changes. Register allocation has been
7818 rewritten. Added customization for the various PICs. Flow
7819 analysis is restructured. ...
7825 Added. device.c is a PIC port hack to accomodate variations
7828 2002-03-13 Michael Hope <michaelh AT vroom>
7830 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7832 2002-03-04 johanknol <johanknol AT manik>
