442 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
443 always available in leading double underscore form. The C99 support is
444 mostly missing, but it's a start.
445 * support/regression/tests/bug-227710.c: fixed nonconforming use of
446 reserved identifier "__data".
448 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

456 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
458 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
461 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

492 immedDom() returning wrong block; probably fixes bug #1160833)
494 2005-03-20 Borut Razem <borut.razem AT siol.net>
496 * support/scripts/inc2h.pl: WIN32 port
498 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

502 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
504 * device/include/stdint.h: added
505 * device/lib/abs.c: added
506 * device/lib/labs.c: added
507 * device/include/stdlib.h: added abs() and labs() prototypes
508 * device/lib/libsdcc.lib: added abs and labs
509 * device/include/float.h,
510 * device/lib/_fsmul.c,
511 * device/lib/printf_fast.c,
512 * device/lib/printf_tiny.c: updated comments
514 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
516 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
519 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
521 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
522 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
524 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
526 * device/lib/printf_large.c: removed inline assembly for portability and
527 readability. Use printf_fast if speed or size are more important.
528 * src/pic16/gen.c: removed conditions around use of DEBUGpc
529 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
531 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
533 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
534 prevent compiler warning
536 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
538 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
539 moved to level 0 and declared as static. Also they are explicit
540 placed in access bank. This was necessery because some times they
541 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
542 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
543 optimizations. Currently only compare to unsigned char is implemented,
544 * src/pic16/gen.c: added fReturnIdx array,
545 * (struct resolvedIfx) is moved to gen.h and made public,
546 * (struct _G): added sregsAlloc and sregsAllocSet fields,
547 * (aopForSym): added an optimization to directly store in stack of
548 the operand of a SEND iCode,
549 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
550 but as registers instead (AOP_REG) using the fReturnIdx array,
551 * (pic16_freeAsmop): remove the freed register from the
553 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
555 * (pic16_popGetTempRegCond): changed function prototype, now
556 function takes also a bitVector argument v which holds the current
557 set of registers that are allocated for stack access by aopForSym,
558 registers allocated in aopForSym for accessing stack symbols are not
559 any more part of the functions usedRegs field,
560 * (genCall): some times aopOp is called for a stack variable to be
561 send, aopForSym might perform the push, if this is true make sure
562 that genCall doesn't push the variable twice by testing _G.resDirect,
563 * (genFunction): changed testing for unspecified interrupt number
564 from 256 to INTNO_UNSPEC,
565 * modified selection scheme of frame pointer generation. Previously
566 if function did use local registers a frame pointer was generated,
567 now a frame pointer is generated only if function has arguments
568 (that need PLUSW2 register access), or has stack arguments, or the
569 compiler is not instructed to omit the frame pointer,
570 * (genEndFunction): before restoring local registers that were saved
571 in the function preamble, also restore the registers that *might*
572 have been allocated for stack access,
573 * (genRet): removed some old comments,
574 * (genCmp, the active (RN's) version): added a call to the
575 pic16_genCmp_special function to perform the compare with a more
576 robust and optimized way,
577 * (genInline): a feature has been added in inline code generation,
578 which allows a wildcard variable substitution when writing inline
579 assembly. Code is incomplete and experimental therefore undocumented,
580 * (genCast): changed order of aopOp for result and right to allow
581 aopForSym to directly load the result if possible,
582 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
583 perform an optimized compare on some selected special occasions,
584 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
585 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
586 generate an IVT any more,
587 * src/pic16/main.c (pic16_optionsTable): added command line option
589 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
590 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
592 * src/pic16/NOTES: Raphael Neider added in list of active developers
593 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
594 jumptable_end to prevent bug #,
595 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
596 inCond and outCond fields,
597 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
598 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
599 turn off register spilling,
600 * (packRegsForOneUse): synced with other ports' versions although it
601 is not used currently,
602 * (pic16_packRegisters): added an optimization while reading
603 structure bitfields, some registers may be saved (malloc code is
604 decreased by 80 bytes)
606 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
608 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
609 left is a bitfield, if yes, then don't optimize assignment. Perhaps
610 this can be optimized more?
612 2005-03-10 Raphael Neider <rneider AT web.de>
614 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
615 genNearPointerGet): (hopefully) fixed access to bitfields via
616 pointers (p->bitN = x; and x = p->bitN; failed)

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

1251 generated for switch statements. For now you need to set the
1252 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1253 Now 4 algorithms for mcs51 jumptable generation are used:
1254 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1286 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1288 * added libc directory. The current version of LibC contains string
1289 functions, ctype functions and macros and some functions of the
1290 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1291 be extensively tested in the future. Standard disclaimer here.
1292 Library is not automatically build yet. But one can build it by

1304 * (pic16_storeForReturn): optimized return of 0,
1305 * (genCmp): experimental code for new genCmp which uses PIC18's
1306 special compare&skip instructions. Initial tests fail some times
1307 with variables grater than 1 byte in size, so new code is disabled,
1308 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1310 * (genCast): began a fix to optimize the casting of a bit to another
1311 bit, now assigning a bitfield to another bitfield will fail, sorry,

1320 and 1 for banking instruction,
1321 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1322 caused stop processing pCodes after a inline assembly block,

1325 registers when it shouldn't,
1326 * src/pic16/ralloc.c (allocReg): add preliminary support for
1327 supporting a limited set of temporary registers,
1329 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1331 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1332 genDataPointerSet): ensure assignments always copy in MSB to LSB
1334 (loadRegFromAop): recognize CLRH optimization,
1335 (genFunction): optimize RECEIVE iCodes in reentrant functions
1337 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1339 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4334 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4336 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4337 loaded with the linker search paths (-L arguments) and the libraries
4338 to be linked with the current source (-l arguments). Changes
4339 currently will affect only the pic16 port.
4340 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4341 include path the port specific paths and port specific libraries,
4342 * gplink command now contains the $3 argument,
4343 * src/pic16/device.h,
4344 * src/pic16/device.c,: structure PIC_device is made public and
4345 renamed to PIC16_device, the same for variable Pics which is renamed

4360 Documenting changes from previous commits.
4361 * configure.in (version 1.56),
4362 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4363 when generating output files to configure the pic16 library,
4364 but now I've commented it out, since gputils aren't installed in the
4365 SF compile farm, so library won't compile
4367 * device/lib/Makefile.in (version 1.56): initially I've added in
4368 target 'all' the prerequestive 'model-pic16' so it compiled the
4369 pic16 library, but now I've commented it out for the same reasons
4371 * added targets 'model-pic16' and 'objects-pic16' to compile the
4373 * added target 'port-specific-objects-pic16' to handle the
4374 generated libraries and copy them into the build/ directory
4375 * added target 'clean-intermediate-pic16' to clean intermediate
4376 files into pic16 directory
4377 * in target 'installdirs' added line to create directory pic16 in
4378 the installation path
4380 * device/include/Makefile.in (version 1.11): in target 'install'
4381 added lines to copy all header files to installation path,
4382 * in target 'installdirs' added line create directory for pic16
4383 headers in the installation path

4398 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4399 option so that it actually works. Made it specific to the z80, since
4400 the gbz80 doesn't have these kinds of I/O ports.
4402 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4404 * device/include/z180.h,

4426 Mainly changes to support compilation of the device libraries
4427 * src/pic16/device.c: stack is allocated via symbol and not
4428 via literal number. The symbol is placed in the corresponding
4429 position of the data ram
4430 * (pic16_dump_section): relocatable and absolute uninitialized
4431 data are now emitted in sorted order to reduce section naming,
4432 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4433 weren't marked as being in the access bank,
4435 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4437 Added portion of GNU PIC Library under the directory
4438 device/include/pic16 and device/lib/pic16. These files
4439 contain the declarations of SFRs for the PIC18Fxx2 devices.
4440 The directory is initialized via configure from toplevel.
4442 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4444 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4451 2004-01-12 Borut Razem <borut.razem AT siol.net>
4453 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
4454 doc/sdccman.lyx: upper case pragmas are deprecated
4456 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4458 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4459 in simpler and even better code

4467 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4469 * doc/sdccman.lyx: Moved and added some sections, small changes
4470 all over. Telling LaTeX to be less strict with word spacing
4471 to better keep the right margin. Changed some notes about
4472 maintainance of the ports in section 3.2.1 - is it OK like this?
4474 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4476 SDCC source changes:
4477 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4483 processor registers declared internally by the port are emitted in
4484 the translation as equates,
4485 * src/pic16/gen.c: inline code is passed unprocessed to the

4511 UPPER for immediate operands,
4512 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4514 * src/pic16/peeph.def: all peepholes with movff are commented out,
4515 because there is a problem in the pcode peep optimizer,
4516 * src/pic16/ralloc.c: the register allocator can now reuse local

4626 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4628 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4629 (default behaviour).
4631 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4633 A python script to validate compiler diagnostic messages. It can be
4634 used to verify that sdcc complains about bad c source code and
4635 gives a good location of the error.
4636 * support/valdiag/Makefile,
4637 * support/valdiag/valdiag.py,
4638 * support/valdiag/tests/*
4640 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4653 * src/common.h: added ifndef/define/endif macros
4654 around the header file.
4655 Bug reported from Jesus Calvino-Fraga
4657 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4659 * sdcc.spec: updated
4660 * device/include/Makefile.in: don't install CVS directories
4661 * device/lib/Makefile.in: added removal of CVS directories after install
4662 * doc/Makefile: fixed install, added local_icons
4663 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4664 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4665 * src/ds390/gen.c (genRightShift): fixed bug #870788
4666 * src/SDCCast.c (decorateType): fixed bug #870781
4668 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4670 PIC16 port related changes:
4671 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4672 added variable stackPos,
4674 * gen.c: genCall, assignResultValue: added support for
4675 pushing/retrieving function parameters to/from stack,
4676 genFunction,genEndFunction: setup stack frame for the
4678 genAddrOf: will be changed according to bug 863624
4680 * added files genutils.c and genutils.h which contain gen*
4681 debugged and optimised functions extracted from gen.c
4683 * glue.c: added variable 'externs' which holds extern symbols,
4684 pic16emitRegularMap: is modified to properly handle relocatable
4685 symbols under the new scheme,
4686 pic16createInterruptVect: is modified
4687 pic16printPublics: is modified to emit 'global' assembler directives,
4688 added pic16_printExterns to print extern symbols,
4689 pic16glue: initializes stack/frame pointer in the beginning of
4690 the assembly output. Temporary hack, will be corrected later,
4691 because gplink yet does not support stack and SDCC does not
4692 yet support a type of crt0.o object to create the final binary.
4694 * Removed many lines that contain 8051 legacy code.
4695 * The code is finally placed under a 'code' directive.
4696 * Added port specific options.
4698 * _process_pragma: simplified since now we do not need *special*
4699 include file to define SFR registers. But a separate header
4700 will be needed. This will be developed later.
4701 * _pic16_parseOptions: added, parses port specific options:
4702 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4703 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4704 --preplace-udata-with=
4706 * _pic16_setDefaultOptions: modified to initialize section names,
4707 but hack is temporarly out of order since it needs improvement.
4708 * _pic16_genAssemblerPreamble: configuration words are emitted by
4709 their address instead of their name. This part is incomplete and
4710 supports only the 18Fxx2 devices. Other devices will emit an error
4711 during assembly since they do not contain the same set of config
4713 * _pic16_genIVT: is modified,
4715 * pcode.c: added definitions for some hardware registers that are needed
4717 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4718 All PCI entries are updated. Now LFSR is supported.
4719 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4720 * added pic16_newpCodeOpLit2 to support instructions with
4721 two literal arguments
4722 * pic16_pCode2str: corrected code that emits assembler instructions
4723 with two literal operands and those that have an access bit modifier
4724 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4725 this fixes a bug which caused some labels to be lost, when an
4726 assembler directive was added, i.e. banksel,
4727 * pic16_FixRegisterBanking: improved logic that causes the insertion
4729 * InlineFunction: functions that are called once, are not any more
4730 inlined. This can be a port option in the future,
4732 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4734 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4735 hold the corresponding uninitialized symbols,
4736 * pic16_allocProcessorRegister: registers have explicit marked the
4738 * pic16_allocInternalRegister: registers are explicit marked as
4740 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4741 processing list, so bit registers were lost,
4744 * ralloc.h: added field 'accessBank' and original symbol operand
4745 in register definition,
4746 * removed the field isMapped from register definition,
4748 ** Several functions have been removed from various sources:
4749 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4750 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4751 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4752 pic16_assignRelocatableRegisters
4754 ** others have been introduced:
4755 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4756 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4758 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4760 * support/scripts/inc2h.pl: changed definition of BIT_AT
4761 to emit 'sbit at' instead of 'bit at'. This was a request.
4763 PIC16 port related preliminary changes:
4764 * gen.c: prefixed function popRegFromString with
4765 pic16_ and all references to it corrected
4766 * pcode.c: all pic16_pc_* hardware registers prefixed
4767 with underscore (_),
4768 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4769 * ralloc.c: newReg(): when register is REG_SFR then
4770 set address to rIdx,
4771 pic16_allocProcessorRegister(): marks register wasUsed=0
4772 pic16_writeUsedRegs(): added a call to assign processor
4773 registers via pic16_assignFixedRegisters
4775 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4777 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4778 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4779 variables in unused register banks. Also the SSEG is placed
4780 wherever there is enough space for it, and IDATA can be anywhere
4781 in internal RAM. For now compile using -Wl-Y[stack_size].
4782 The mem file is different for this option as well, since it
4783 makes no sense of talking about DSEG lenght.
4785 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4787 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4788 in certain cases, e.g. when ROM assignment, patch provided
4789 from Albert den Haan.
4791 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4934 * src/mcs51/peephole.def,
4935 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4936 (allows non-interrupt and interrupt code to safely compete for a resource

5814 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5815 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

5834 A few small changes that speed up the peephole optimizer.
5838 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5840 Try to make the peephole optimizer smarter by maintaining
5841 an association between the assembly source code and the
5842 iCodes that originated them. Put this information to use
5843 with a new peephole rule condition "notVolatile" so that
5844 the rules can be aggressive yet still safe.
5849 * src/mcs51/peeph.def
5851 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5855 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5856 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5857 if the left or right operand symbols have the accuse flag set.
5859 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5861 Changed the type of the result of the ! (NOT) operator to char;
5862 previously it returned the same type as the source. This allows
5863 us to eliminate all the genFloatNot functions (all of its target
5864 implementations were very buggy) since !float can use the same
5867 * src/SDCCicode.c (ast2iCode): ! returns char

5876 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5877 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5878 during interrupts. Ensure WSAVE is located at a shared bank address.
5879 2. Fixed page selection in some places
5880 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5881 the registers name strings.
5882 4. Fixed "signed / unsigned compare" compiler warnings.
5883 5. The PIC port manages its own allocation of the general purpose
5884 registers, but makes no attempt to reuse them. As a result when
5885 compiling it soon runs out of general purpose registers. Some
5886 additional code was added to the files pcode.c and device.c to walk
5887 through the function call tree and rename the registers so that they
5897 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5904 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5906 Made bitfield a distinct type from bit so that bitfields
5907 convert as per ANSI C and bits retain their traditional
5908 boolean style behaviour. Implemented bitfield support in
5916 * src/ds390/gen.c: bit v bitfield split
5917 * src/z80/gen.c: New support for bitfields
5918 * support/regression/tests/bitfields.c: reenabled z80,
5921 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5923 Rules 246.x, 247.x relate to bitfields, the others speed up
5924 access to xdata mapped I/O devices.
5926 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5928 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5930 Cleaned up genPackBits and genUnpackBits and added two helper

5940 Fixed bug #748310 (pointer to function type mishandled when the
5941 function name is omitted). Also fixed a SIGSEGV when a function
5942 attribute (reentrant, etc) is used on a non-function or on a
5943 function but misplaced before the parameter list.

5970 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5972 Made the constant following the "interrupt" keyword optional. If
5973 omitted, the function will not automatically be given an entry
5974 in the interrupt vector table (similar to #pragma NOIV, but
5975 less syntacticly kludgy). The interrupt number is also now
5976 range checked. Also fixed a bug in the high order bit example
5983 * support/Util/SDCCerr.c
5984 * support/Util/SDCCerr.h

6044 * src/SDCCval.c (valDiv, valMod): fixed signdness
6045 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6046 signedness of modulo, left and right shift

6508 support for the PIc16 port in the ports table, when executing
6509 the compiler with no port specified on command line, a default
6510 port is selected with the new macro DEFAULT_PORT which is
6511 defined in port.h, in setDefaultOptions() linkOptions is removed
6512 from initialization assignment, since now it is a set,
6513 parseCmdLine uses setParseWithComma for linkOptions, in
6514 linkEdit() linkOptions are accessed with new function indexSet()
6515 which returns the i'th item of a set variable. See SDCCset.c, in
6516 linkEdit() when calling buildCmdLine(), added linkOptions as
6517 last argument. Now users can pass arguments to gplink via the

7582 2003-01-04 <johan AT balder>
7584 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7586 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7587 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7589 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7590 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7599 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7600 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7602 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7604 * in \sdcc\as\mcs51\ changed these files in order to create an
7605 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7606 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7607 following files to include the previous two files: aslink.dsp,
7608 Makefile.aslink, Makefile.bcc, and Makefile.in.
7610 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7611 .adb instead of .cdb
7613 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7615 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7616 value from option --iram-size.
7618 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7620 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7623 2002-09-18 <wiml AT hhhh.org>
7625 * SDCClrange.h: exposed setFromRange() and setToRange()
7626 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7627 packRegsForAccUse() (bug 542397)
7628 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7629 multiple times and emitting the fetch operations more than once
7630 added aopGetUsesAcc() function to allow binary operators to
7631 fetch their operands in the correct order; made genMinus() emit
7632 compact code for X = LITERAL - Y
7634 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7635 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7636 sprintf() in line 1267.
7638 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7639 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7642 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7643 Changes to aslink (All the changes are marked with 'JCF'):
7645 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7648 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7649 area BSEG. Also moves, if possible, the DATA area down into the internal
7650 ram so more space is available.
7652 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7655 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7656 not bytes. Function summary() which creates a memory usage summary
7657 file with extension .mem. Reports of overlaping stack and small stack
7658 size. If the space for the stack is less than 16 bytes aslink trows a
7661 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7662 the 8051. Option 'y' for memory summary output file.
7664 Changes to sdcc (All the changes are marked with 'JCF'):
7666 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7668 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7669 overlaying area for it (uses RegBankUsed[4]).
7671 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7672 bank zero as used by default. By default aslink locates the stack
7673 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7674 the creation of the .mem file. Delegates the allocation of data area
7675 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7676 the begining of the stack area to aslink.
7678 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7679 glue() in SDCCglue.c creates an area for it.
7681 2002-09-03 Borut Razem <borut.razem AT siol.net>
7682 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7683 sdcc/src/pic/glue.c:
7684 introduced atexit() handler for teporay files removal in case of
7685 errors, assertions, ...
7687 2002-08-29 Borut Razem <borut.razem AT siol.net>
7688 * sdcc/support/cpp2/auto-host_vc_in.h:
7689 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7690 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7691 Maybe there is a similar problem with BORLANDC? It should be checked!
7693 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7694 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7695 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7696 was not executed, and the compiler (cl) launched a warning:
7697 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7699 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7700 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7702 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7703 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7705 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7706 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7707 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7708 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7709 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7710 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7711 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7712 - added Release configuration in VS projects
7713 - review of compiler an linker options
7714 - VC .exe files are generated in bin_vc directory, not to interfere
7715 with binaries generated from other projects (cygwin, mingw, bcc ...)
7717 * sdcc/src/yacc.dsp: added
7719 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7720 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7721 and insert the version number definitions from .version
7723 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7725 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7726 added - genarate auto-host.h using auto-host_vc_in.h as template
7729 removed from CVS, generated automatically
7731 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7732 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7734 2002-08-11 Borut Razem <borut.razem AT siol.net>
7735 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7737 2002-08-10 Borut Razem <borut.razem AT siol.net>
7738 * src/SDCCmain.c (main):
7739 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7740 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7741 The consequence was that some temporary files were not removed.
7744 unification of code in functions tempfilename() and tempfile():
7745 function tempnam() is defined in Visual Studio 6.0 and .NET
7747 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7749 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7750 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7751 - removed compiler command line option /WX: Treats all warnings as errors
7752 - update a list of source files, included into the project
7754 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7755 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7756 changed project type to Generic Project so that can be correcly converted to VS.NET project
7758 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7760 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7762 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7764 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7765 added return 0 statements after assert() to make compiler happy
7767 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7768 added newline in the def file to keep MSC compiler satisfied
7770 * sdcc/src/z80/gen.c:
7771 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7772 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7773 - solved MSC error in function aopDump()
7775 * sdcc_vc.h: define PREFIX as "\\sdcc"
7777 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7778 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7780 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7781 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7782 - Rewrote the register banking algorithm.
7783 - Added pCode live-range analysis to registers (for now, only non-used and
7784 singly-used registers optimized away)
7786 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7788 * 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.
7790 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7791 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7793 2002-04-22 Michael Hope <michaelh AT vroom>

7809 * src/z80/peeph.def: Added transpose redundent load rule.
7811 * src/z80/main.c: Added force callee saves for jaune.
7813 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7815 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7817 2002-03-28 Johan Knol <johan AT balder>
7819 * src/SDCCval.c: fixed bug #532436
7821 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7823 Added "char *Processor" field to the port structure.
7826 Added -p option. Allows port dependent processor to be specified.
7829 Initialized the new field char *Processor field to NULL in all ports
7832 Compiler generated registers for interrupt context saving
7833 were not getting allocated.
7835 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7838 Fixed left shift. Will promote the left side of a left shift
7839 if a) left shifting more than size of operand or b) when assigned
7840 to something size > size of left side
7842 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7844 tons of changes. Register allocation has been
7845 rewritten. Added customization for the various PICs. Flow
7846 analysis is restructured. ...
7852 Added. device.c is a PIC port hack to accomodate variations
7855 2002-03-13 Michael Hope <michaelh AT vroom>
7857 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7859 2002-03-04 johanknol <johanknol AT manik>
7861 * /src/SDCCval.c: fixed
7863 const unsigned char arr[][2] = { { 0, 1 } };
