508 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
509 on rIfx (genCmp was broken)
511 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
513 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
514 * src/z80/main.c (_keywords[]),
515 * src/SDCCglobal.h (struct options),
517 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
518 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
519 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
520 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
521 always available in leading double underscore form. The C99 support is
522 mostly missing, but it's a start.
523 * support/regression/tests/bug-227710.c: fixed nonconforming use of
524 reserved identifier "__data".
526 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

572 2005-03-20 Borut Razem <borut.razem AT siol.net>
574 * support/scripts/inc2h.pl: WIN32 port

600 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
602 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
604 * device/lib/printf_large.c: removed inline assembly for portability and
605 readability. Use printf_fast if speed or size are more important.
606 * src/pic16/gen.c: removed conditions around use of DEBUGpc
607 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
609 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
611 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
612 prevent compiler warning
614 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
616 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
617 moved to level 0 and declared as static. Also they are explicit
618 placed in access bank. This was necessery because some times they
619 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
620 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
621 optimizations. Currently only compare to unsigned char is implemented,
622 * src/pic16/gen.c: added fReturnIdx array,
623 * (struct resolvedIfx) is moved to gen.h and made public,
624 * (struct _G): added sregsAlloc and sregsAllocSet fields,
625 * (aopForSym): added an optimization to directly store in stack of
626 the operand of a SEND iCode,
627 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
628 but as registers instead (AOP_REG) using the fReturnIdx array,
629 * (pic16_freeAsmop): remove the freed register from the
631 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
633 * (pic16_popGetTempRegCond): changed function prototype, now
634 function takes also a bitVector argument v which holds the current
635 set of registers that are allocated for stack access by aopForSym,
636 registers allocated in aopForSym for accessing stack symbols are not
637 any more part of the functions usedRegs field,
638 * (genCall): some times aopOp is called for a stack variable to be
639 send, aopForSym might perform the push, if this is true make sure
640 that genCall doesn't push the variable twice by testing _G.resDirect,
641 * (genFunction): changed testing for unspecified interrupt number
642 from 256 to INTNO_UNSPEC,
643 * modified selection scheme of frame pointer generation. Previously
644 if function did use local registers a frame pointer was generated,
645 now a frame pointer is generated only if function has arguments
646 (that need PLUSW2 register access), or has stack arguments, or the
647 compiler is not instructed to omit the frame pointer,
648 * (genEndFunction): before restoring local registers that were saved
649 in the function preamble, also restore the registers that *might*
650 have been allocated for stack access,
651 * (genRet): removed some old comments,
652 * (genCmp, the active (RN's) version): added a call to the
653 pic16_genCmp_special function to perform the compare with a more
654 robust and optimized way,
655 * (genInline): a feature has been added in inline code generation,
656 which allows a wildcard variable substitution when writing inline
657 assembly. Code is incomplete and experimental therefore undocumented,
658 * (genCast): changed order of aopOp for result and right to allow
659 aopForSym to directly load the result if possible,
660 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
661 perform an optimized compare on some selected special occasions,
662 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
663 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
664 generate an IVT any more,
665 * src/pic16/main.c (pic16_optionsTable): added command line option
667 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
668 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
670 * src/pic16/NOTES: Raphael Neider added in list of active developers
671 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
672 jumptable_end to prevent bug #,
673 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
674 inCond and outCond fields,
675 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
676 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
677 turn off register spilling,
678 * (packRegsForOneUse): synced with other ports' versions although it
679 is not used currently,
680 * (pic16_packRegisters): added an optimization while reading
681 structure bitfields, some registers may be saved (malloc code is
682 decreased by 80 bytes)
684 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
686 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
687 left is a bitfield, if yes, then don't optimize assignment. Perhaps
688 this can be optimized more?
690 2005-03-10 Raphael Neider <rneider AT web.de>
692 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
693 genNearPointerGet): (hopefully) fixed access to bitfields via
694 pointers (p->bitN = x; and x = p->bitN; failed)
696 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
698 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

884 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
885 this might fix SIGSEGVs on MinGW...
886 * src/SDCCopt.c (killDeadCode): restored original behaviour
887 (volatile operands might get thrown away though)
889 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1352 * src/pic16/device.h,
1353 * src/pic16/genarith.c,
1356 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1358 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1360 Large cummulative patch for pic16 port.
1361 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1362 to call when a stack overflow occurs,
1363 * (malloc.h): added CVS Id tag,
1364 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1366 * added libc directory. The current version of LibC contains string
1367 functions, ctype functions and macros and some functions of the
1368 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1369 be extensively tested in the future. Standard disclaimer here.
1370 Library is not automatically build yet. But one can build it by
1371 invoking 'make' inside the libc directory.
1372 * added ADC library under libio. Preliminary version yet.
1374 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1375 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1376 aopForRemat() now and not by pic16_aopOp(),
1377 * (pic16_popGetTempReg): removed warning messgae when allocating
1378 temporary registers, its a buggy feature and will be removed,
1379 * (pic16_popGet): set register instance field in AOP_CRY,
1380 * (pic16_outBitC): fixed for results in size greater than 1,
1381 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1382 * (pic16_storeForReturn): optimized return of 0,
1383 * (genCmp): experimental code for new genCmp which uses PIC18's
1384 special compare&skip instructions. Initial tests fail some times
1385 with variables grater than 1 byte in size, so new code is disabled,
1386 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1388 * (genCast): began a fix to optimize the casting of a bit to another
1389 bit, now assigning a bitfield to another bitfield will fail, sorry,
1390 * src/pic16/main.c: disabled the use of lr-support feature,
1391 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1392 * added some function prototypes, added function _debugf prototype,
1393 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1394 bits with offset (case PO_GPR_BIT),
1395 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1397 * (isBankInstruction): modified to return 0 for no banking instruction,
1398 and 1 for banking instruction,
1399 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1400 caused stop processing pCodes after a inline assembly block,
1401 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1402 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1403 registers when it shouldn't,
1404 * src/pic16/ralloc.c (allocReg): add preliminary support for
1405 supporting a limited set of temporary registers,
1407 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1409 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1410 genDataPointerSet): ensure assignments always copy in MSB to LSB
1412 (loadRegFromAop): recognize CLRH optimization,
1413 (genFunction): optimize RECEIVE iCodes in reentrant functions
1415 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1417 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1418 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1420 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1426 * device/lib/_gptrget.c (_gptrget),
1427 * device/lib/_gptrgetc.c (_gptrgetc),
1428 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1429 instead of sjmp to ret
1430 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1431 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

4415 loaded with the linker search paths (-L arguments) and the libraries
4416 to be linked with the current source (-l arguments). Changes
4417 currently will affect only the pic16 port.
4418 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4419 include path the port specific paths and port specific libraries,

4440 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4441 when generating output files to configure the pic16 library,
4442 but now I've commented it out, since gputils aren't installed in the
4443 SF compile farm, so library won't compile
4445 * device/lib/Makefile.in (version 1.56): initially I've added in
4446 target 'all' the prerequestive 'model-pic16' so it compiled the
4447 pic16 library, but now I've commented it out for the same reasons
4449 * added targets 'model-pic16' and 'objects-pic16' to compile the
4451 * added target 'port-specific-objects-pic16' to handle the
4452 generated libraries and copy them into the build/ directory
4453 * added target 'clean-intermediate-pic16' to clean intermediate
4454 files into pic16 directory
4455 * in target 'installdirs' added line to create directory pic16 in
4456 the installation path
4458 * device/include/Makefile.in (version 1.11): in target 'install'
4459 added lines to copy all header files to installation path,
4460 * in target 'installdirs' added line create directory for pic16
4461 headers in the installation path

4476 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4477 option so that it actually works. Made it specific to the z80, since
4478 the gbz80 doesn't have these kinds of I/O ports.
4480 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4482 * device/include/z180.h,

4493 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4495 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4497 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

4504 Mainly changes to support compilation of the device libraries
4505 * src/pic16/device.c: stack is allocated via symbol and not
4506 via literal number. The symbol is placed in the corresponding
4507 position of the data ram
4508 * (pic16_dump_section): relocatable and absolute uninitialized
4509 data are now emitted in sorted order to reduce section naming,
4510 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4511 weren't marked as being in the access bank,
4513 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4515 Added portion of GNU PIC Library under the directory
4516 device/include/pic16 and device/lib/pic16. These files
4517 contain the declarations of SFRs for the PIC18Fxx2 devices.
4518 The directory is initialized via configure from toplevel.
4520 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4522 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4523 the spilllocations to be compared correctly

4547 * doc/sdccman.lyx: Moved and added some sections, small changes
4548 all over. Telling LaTeX to be less strict with word spacing
4549 to better keep the right margin. Changed some notes about
4550 maintainance of the ports in section 3.2.1 - is it OK like this?
4552 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4589 UPPER for immediate operands,
4590 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4592 * src/pic16/peeph.def: all peepholes with movff are commented out,
4593 because there is a problem in the pcode peep optimizer,
4594 * src/pic16/ralloc.c: the register allocator can now reuse local

4596 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4598 Added file src/pic16/NOTES with information about program writing on
4599 the current port version.

4687 include information about variables allocated to the overlay
4690 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4692 * as/mcs51/lkmain.c: Help about -Y option

4704 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4706 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4707 (default behaviour).
4709 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4711 A python script to validate compiler diagnostic messages. It can be
4712 used to verify that sdcc complains about bad c source code and
4713 gives a good location of the error.
4714 * support/valdiag/Makefile,
4715 * support/valdiag/valdiag.py,
4716 * support/valdiag/tests/*

4733 Bug reported from Jesus Calvino-Fraga
4735 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4737 * sdcc.spec: updated
4738 * device/include/Makefile.in: don't install CVS directories
4739 * device/lib/Makefile.in: added removal of CVS directories after install
4740 * doc/Makefile: fixed install, added local_icons
4741 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4742 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4743 * src/ds390/gen.c (genRightShift): fixed bug #870788
4744 * src/SDCCast.c (decorateType): fixed bug #870781
4746 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4748 PIC16 port related changes:
4749 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4750 added variable stackPos,
4752 * gen.c: genCall, assignResultValue: added support for
4753 pushing/retrieving function parameters to/from stack,
4754 genFunction,genEndFunction: setup stack frame for the
4756 genAddrOf: will be changed according to bug 863624
4758 * added files genutils.c and genutils.h which contain gen*
4759 debugged and optimised functions extracted from gen.c
4761 * glue.c: added variable 'externs' which holds extern symbols,
4762 pic16emitRegularMap: is modified to properly handle relocatable
4763 symbols under the new scheme,
4764 pic16createInterruptVect: is modified
4765 pic16printPublics: is modified to emit 'global' assembler directives,
4766 added pic16_printExterns to print extern symbols,
4767 pic16glue: initializes stack/frame pointer in the beginning of
4768 the assembly output. Temporary hack, will be corrected later,
4769 because gplink yet does not support stack and SDCC does not
4770 yet support a type of crt0.o object to create the final binary.
4772 * Removed many lines that contain 8051 legacy code.
4773 * The code is finally placed under a 'code' directive.
4774 * Added port specific options.
4776 * _process_pragma: simplified since now we do not need *special*
4777 include file to define SFR registers. But a separate header
4778 will be needed. This will be developed later.
4779 * _pic16_parseOptions: added, parses port specific options:
4780 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4781 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4782 --preplace-udata-with=
4784 * _pic16_setDefaultOptions: modified to initialize section names,
4785 but hack is temporarly out of order since it needs improvement.
4786 * _pic16_genAssemblerPreamble: configuration words are emitted by
4787 their address instead of their name. This part is incomplete and
4788 supports only the 18Fxx2 devices. Other devices will emit an error
4789 during assembly since they do not contain the same set of config
4791 * _pic16_genIVT: is modified,
4793 * pcode.c: added definitions for some hardware registers that are needed
4795 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4796 All PCI entries are updated. Now LFSR is supported.
4797 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4798 * added pic16_newpCodeOpLit2 to support instructions with
4799 two literal arguments
4800 * pic16_pCode2str: corrected code that emits assembler instructions
4801 with two literal operands and those that have an access bit modifier
4802 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4803 this fixes a bug which caused some labels to be lost, when an
4804 assembler directive was added, i.e. banksel,
4805 * pic16_FixRegisterBanking: improved logic that causes the insertion
4807 * InlineFunction: functions that are called once, are not any more
4808 inlined. This can be a port option in the future,
4810 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4812 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4813 hold the corresponding uninitialized symbols,
4814 * pic16_allocProcessorRegister: registers have explicit marked the
4816 * pic16_allocInternalRegister: registers are explicit marked as
4818 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4819 processing list, so bit registers were lost,
4822 * ralloc.h: added field 'accessBank' and original symbol operand
4823 in register definition,
4824 * removed the field isMapped from register definition,
4826 ** Several functions have been removed from various sources:
4827 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4828 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4829 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4830 pic16_assignRelocatableRegisters
4832 ** others have been introduced:
4833 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4834 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4836 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4838 * support/scripts/inc2h.pl: changed definition of BIT_AT
4839 to emit 'sbit at' instead of 'bit at'. This was a request.
4841 PIC16 port related preliminary changes:
4842 * gen.c: prefixed function popRegFromString with
4843 pic16_ and all references to it corrected
4844 * pcode.c: all pic16_pc_* hardware registers prefixed
4845 with underscore (_),
4846 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4847 * ralloc.c: newReg(): when register is REG_SFR then
4848 set address to rIdx,
4849 pic16_allocProcessorRegister(): marks register wasUsed=0
4850 pic16_writeUsedRegs(): added a call to assign processor
4851 registers via pic16_assignFixedRegisters
4853 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4855 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4856 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4857 variables in unused register banks. Also the SSEG is placed
4858 wherever there is enough space for it, and IDATA can be anywhere
4859 in internal RAM. For now compile using -Wl-Y[stack_size].
4860 The mem file is different for this option as well, since it
4861 makes no sense of talking about DSEG lenght.
4863 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4865 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4866 in certain cases, e.g. when ROM assignment, patch provided
4867 from Albert den Haan.
4869 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5422 not occur if the control variable is involved with a
5423 relational operator.

5916 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5918 Try to make the peephole optimizer smarter by maintaining
5919 an association between the assembly source code and the
5920 iCodes that originated them. Put this information to use
5921 with a new peephole rule condition "notVolatile" so that
5922 the rules can be aggressive yet still safe.

5935 if the left or right operand symbols have the accuse flag set.
5937 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5939 Changed the type of the result of the ! (NOT) operator to char;
5940 previously it returned the same type as the source. This allows
5941 us to eliminate all the genFloatNot functions (all of its target
5942 implementations were very buggy) since !float can use the same
5945 * src/SDCCicode.c (ast2iCode): ! returns char

5954 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5955 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5956 during interrupts. Ensure WSAVE is located at a shared bank address.
5957 2. Fixed page selection in some places
5958 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5959 the registers name strings.
5960 4. Fixed "signed / unsigned compare" compiler warnings.
5961 5. The PIC port manages its own allocation of the general purpose
5962 registers, but makes no attempt to reuse them. As a result when
5963 compiling it soon runs out of general purpose registers. Some
5964 additional code was added to the files pcode.c and device.c to walk
5965 through the function call tree and rename the registers so that they
5975 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5982 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5984 Made bitfield a distinct type from bit so that bitfields
5985 convert as per ANSI C and bits retain their traditional
5986 boolean style behaviour. Implemented bitfield support in
5994 * src/ds390/gen.c: bit v bitfield split
5995 * src/z80/gen.c: New support for bitfields
5996 * support/regression/tests/bitfields.c: reenabled z80,
5999 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6001 Rules 246.x, 247.x relate to bitfields, the others speed up
6002 access to xdata mapped I/O devices.
6004 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6006 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6008 Cleaned up genPackBits and genUnpackBits and added two helper
6009 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6010 for literal assignments in genPackBits (thanks to Frieder for
6016 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6018 Fixed bug #748310 (pointer to function type mishandled when the
6019 function name is omitted). Also fixed a SIGSEGV when a function
6020 attribute (reentrant, etc) is used on a non-function or on a
6021 function but misplaced before the parameter list.

6048 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6050 Made the constant following the "interrupt" keyword optional. If
6051 omitted, the function will not automatically be given an entry
6052 in the interrupt vector table (similar to #pragma NOIV, but
6053 less syntacticly kludgy). The interrupt number is also now
6054 range checked. Also fixed a bug in the high order bit example

6530 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6531 the regression tests I'm not brave enough to enable 245.b, 245.c
6532 * doc/sdccman.lyx: added latex preamble for hyperref package.
6533 Using pdflatex this will give you a hyperlinked pdf file with
6534 bookmarks. (prepend '%' before /usepackage if this breaks something)

6575 it can be defined with CFLAGS when running configure
6576 * src/SDCCmain.c: fixed compiling + linking with object files
6578 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6581 added --disable-pic16-port
6582 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6583 * src/SDCCmain.c: linkOptions is changed to set *,
6584 added if/endif conditional macros to remove options help
6585 messages from optionsTable when a port is not configured, added
6586 support for the PIc16 port in the ports table, when executing
6587 the compiler with no port specified on command line, a default
6588 port is selected with the new macro DEFAULT_PORT which is
6589 defined in port.h, in setDefaultOptions() linkOptions is removed
6590 from initialization assignment, since now it is a set,
6591 parseCmdLine uses setParseWithComma for linkOptions, in
6592 linkEdit() linkOptions are accessed with new function indexSet()
6593 which returns the i'th item of a set variable. See SDCCset.c, in
6594 linkEdit() when calling buildCmdLine(), added linkOptions as
6595 last argument. Now users can pass arguments to gplink via the
6596 -Wl option, main() uses pic16glue() to glue up pic16 programs

6608 * src/pic16/glue.c: commented out some error producing lines
6609 * src/pic16/main.c: __config directives are commented out to stop
6610 gpasm complaining and test the linkage with gplink, _linkCmd and
6611 _asmCmd changed to be more gplink and gpasm friendly
6612 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6613 produced an error when parsed, peep rule 12 is added to utilize
6614 movff, but it is commented out since the pCode does not support
6615 yet a command with 2 address arguments
6617 2003-05-18 <johan AT balder>
6619 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6644 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6646 2003-05-11 Borut Razem <borut.razem AT siol.net>
6648 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6649 the path of bin directory, so that PATH is the only env. variable, which has to be set
6650 in case of standard installation.
6651 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7654 * src/SDCCicode.c: fixed array add
7656 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7657 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7658 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7660 2003-01-04 <johan AT balder>
7662 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7664 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7665 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7677 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7678 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7680 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7682 * in \sdcc\as\mcs51\ changed these files in order to create an
7683 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7684 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7685 following files to include the previous two files: aslink.dsp,
7686 Makefile.aslink, Makefile.bcc, and Makefile.in.
7688 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7689 .adb instead of .cdb
7691 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7693 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7694 value from option --iram-size.
7696 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7698 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7701 2002-09-18 <wiml AT hhhh.org>
7703 * SDCClrange.h: exposed setFromRange() and setToRange()
7704 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7705 packRegsForAccUse() (bug 542397)
7706 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7707 multiple times and emitting the fetch operations more than once
7708 added aopGetUsesAcc() function to allow binary operators to
7709 fetch their operands in the correct order; made genMinus() emit
7710 compact code for X = LITERAL - Y
7712 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7713 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7714 sprintf() in line 1267.
7716 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7717 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7720 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7721 Changes to aslink (All the changes are marked with 'JCF'):
7723 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7726 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7727 area BSEG. Also moves, if possible, the DATA area down into the internal
7728 ram so more space is available.
7730 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7733 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7734 not bytes. Function summary() which creates a memory usage summary
7735 file with extension .mem. Reports of overlaping stack and small stack
7736 size. If the space for the stack is less than 16 bytes aslink trows a
7739 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7740 the 8051. Option 'y' for memory summary output file.
7742 Changes to sdcc (All the changes are marked with 'JCF'):
7744 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7746 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7747 overlaying area for it (uses RegBankUsed[4]).
7749 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7750 bank zero as used by default. By default aslink locates the stack
7751 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7752 the creation of the .mem file. Delegates the allocation of data area
7753 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7754 the begining of the stack area to aslink.
7756 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7757 glue() in SDCCglue.c creates an area for it.
7759 2002-09-03 Borut Razem <borut.razem AT siol.net>
7760 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7761 sdcc/src/pic/glue.c:
7762 introduced atexit() handler for teporay files removal in case of
7763 errors, assertions, ...
7765 2002-08-29 Borut Razem <borut.razem AT siol.net>
7766 * sdcc/support/cpp2/auto-host_vc_in.h:
7767 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7768 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7769 Maybe there is a similar problem with BORLANDC? It should be checked!
7771 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7772 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7773 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7774 was not executed, and the compiler (cl) launched a warning:
7775 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7777 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7778 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7780 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7781 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7783 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7784 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

7786 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7787 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7788 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7789 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7790 - added Release configuration in VS projects
7791 - review of compiler an linker options
7792 - VC .exe files are generated in bin_vc directory, not to interfere
7793 with binaries generated from other projects (cygwin, mingw, bcc ...)
7795 * sdcc/src/yacc.dsp: added
7797 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7798 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7799 and insert the version number definitions from .version
7801 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7803 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7804 added - genarate auto-host.h using auto-host_vc_in.h as template
7807 removed from CVS, generated automatically
7809 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7810 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7812 2002-08-11 Borut Razem <borut.razem AT siol.net>
7813 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7815 2002-08-10 Borut Razem <borut.razem AT siol.net>
7816 * src/SDCCmain.c (main):
7817 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7818 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7819 The consequence was that some temporary files were not removed.
7822 unification of code in functions tempfilename() and tempfile():
7823 function tempnam() is defined in Visual Studio 6.0 and .NET
7825 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7827 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7828 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7829 - removed compiler command line option /WX: Treats all warnings as errors
7830 - update a list of source files, included into the project
7832 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7833 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:

8030 * sdcc/src/SDCCloop.c:
8031 Previous fix was not good. basic blocks that have "break" or "return" are
8032 not really partof a loop , but live ranges used in these blocks should
8033 be live thru the entire loop, so set partOfLoop but don't add them to
