483 2005-03-20 Borut Razem <borut.razem AT siol.net>
485 * support/scripts/inc2h.pl: WIN32 port
487 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

498 * device/include/float.h,
499 * device/lib/_fsmul.c,
500 * device/lib/printf_fast.c,
501 * device/lib/printf_tiny.c: updated comments
503 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
505 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
508 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
510 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
511 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
513 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
515 * device/lib/printf_large.c: removed inline assembly for portability and
516 readability. Use printf_fast if speed or size are more important.
517 * src/pic16/gen.c: removed conditions around use of DEBUGpc
518 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
520 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
522 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
523 prevent compiler warning
525 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
527 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
528 moved to level 0 and declared as static. Also they are explicit
529 placed in access bank. This was necessery because some times they
530 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
531 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
532 optimizations. Currently only compare to unsigned char is implemented,
533 * src/pic16/gen.c: added fReturnIdx array,
534 * (struct resolvedIfx) is moved to gen.h and made public,
535 * (struct _G): added sregsAlloc and sregsAllocSet fields,
536 * (aopForSym): added an optimization to directly store in stack of
537 the operand of a SEND iCode,
538 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
539 but as registers instead (AOP_REG) using the fReturnIdx array,
540 * (pic16_freeAsmop): remove the freed register from the
542 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
544 * (pic16_popGetTempRegCond): changed function prototype, now
545 function takes also a bitVector argument v which holds the current
546 set of registers that are allocated for stack access by aopForSym,
547 registers allocated in aopForSym for accessing stack symbols are not
548 any more part of the functions usedRegs field,
549 * (genCall): some times aopOp is called for a stack variable to be
550 send, aopForSym might perform the push, if this is true make sure
551 that genCall doesn't push the variable twice by testing _G.resDirect,
552 * (genFunction): changed testing for unspecified interrupt number
553 from 256 to INTNO_UNSPEC,
554 * modified selection scheme of frame pointer generation. Previously
555 if function did use local registers a frame pointer was generated,
556 now a frame pointer is generated only if function has arguments
557 (that need PLUSW2 register access), or has stack arguments, or the
558 compiler is not instructed to omit the frame pointer,
559 * (genEndFunction): before restoring local registers that were saved
560 in the function preamble, also restore the registers that *might*
561 have been allocated for stack access,
562 * (genRet): removed some old comments,
563 * (genCmp, the active (RN's) version): added a call to the
564 pic16_genCmp_special function to perform the compare with a more
565 robust and optimized way,
566 * (genInline): a feature has been added in inline code generation,
567 which allows a wildcard variable substitution when writing inline
568 assembly. Code is incomplete and experimental therefore undocumented,
569 * (genCast): changed order of aopOp for result and right to allow
570 aopForSym to directly load the result if possible,
571 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
572 perform an optimized compare on some selected special occasions,
573 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
574 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
575 generate an IVT any more,
576 * src/pic16/main.c (pic16_optionsTable): added command line option
578 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
579 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
581 * src/pic16/NOTES: Raphael Neider added in list of active developers
582 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
583 jumptable_end to prevent bug #,
584 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
585 inCond and outCond fields,
586 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
587 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
588 turn off register spilling,
589 * (packRegsForOneUse): synced with other ports' versions although it
590 is not used currently,
591 * (pic16_packRegisters): added an optimization while reading
592 structure bitfields, some registers may be saved (malloc code is
593 decreased by 80 bytes)
595 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
597 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
598 left is a bitfield, if yes, then don't optimize assignment. Perhaps
599 this can be optimized more?
601 2005-03-10 Raphael Neider <rneider AT web.de>
603 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
604 genNearPointerGet): (hopefully) fixed access to bitfields via
605 pointers (p->bitN = x; and x = p->bitN; failed)

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

1277 * added libc directory. The current version of LibC contains string
1278 functions, ctype functions and macros and some functions of the
1279 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1280 be extensively tested in the future. Standard disclaimer here.
1281 Library is not automatically build yet. But one can build it by

1293 * (pic16_storeForReturn): optimized return of 0,
1294 * (genCmp): experimental code for new genCmp which uses PIC18's
1295 special compare&skip instructions. Initial tests fail some times
1296 with variables grater than 1 byte in size, so new code is disabled,
1297 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1299 * (genCast): began a fix to optimize the casting of a bit to another
1300 bit, now assigning a bitfield to another bitfield will fail, sorry,

1315 * src/pic16/ralloc.c (allocReg): add preliminary support for
1316 supporting a limited set of temporary registers,
1318 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4323 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4325 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4326 loaded with the linker search paths (-L arguments) and the libraries
4327 to be linked with the current source (-l arguments). Changes
4328 currently will affect only the pic16 port.
4329 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4330 include path the port specific paths and port specific libraries,
4331 * gplink command now contains the $3 argument,
4332 * src/pic16/device.h,
4333 * src/pic16/device.c,: structure PIC_device is made public and
4334 renamed to PIC16_device, the same for variable Pics which is renamed

4349 Documenting changes from previous commits.
4350 * configure.in (version 1.56),
4351 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4352 when generating output files to configure the pic16 library,
4353 but now I've commented it out, since gputils aren't installed in the
4354 SF compile farm, so library won't compile
4356 * device/lib/Makefile.in (version 1.56): initially I've added in
4357 target 'all' the prerequestive 'model-pic16' so it compiled the
4358 pic16 library, but now I've commented it out for the same reasons
4360 * added targets 'model-pic16' and 'objects-pic16' to compile the
4362 * added target 'port-specific-objects-pic16' to handle the
4363 generated libraries and copy them into the build/ directory
4364 * added target 'clean-intermediate-pic16' to clean intermediate
4365 files into pic16 directory
4366 * in target 'installdirs' added line to create directory pic16 in
4367 the installation path

4370 added lines to copy all header files to installation path,
4371 * in target 'installdirs' added line create directory for pic16
4372 headers in the installation path

4388 option so that it actually works. Made it specific to the z80, since
4389 the gbz80 doesn't have these kinds of I/O ports.
4391 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4393 * device/include/z180.h,

4417 via literal number. The symbol is placed in the corresponding
4418 position of the data ram
4419 * (pic16_dump_section): relocatable and absolute uninitialized
4420 data are now emitted in sorted order to reduce section naming,
4421 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4422 weren't marked as being in the access bank,
4424 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4426 Added portion of GNU PIC Library under the directory
4427 device/include/pic16 and device/lib/pic16. These files
4428 contain the declarations of SFRs for the PIC18Fxx2 devices.
4429 The directory is initialized via configure from toplevel.

4458 * doc/sdccman.lyx: Moved and added some sections, small changes
4459 all over. Telling LaTeX to be less strict with word spacing
4460 to better keep the right margin. Changed some notes about
4461 maintainance of the ports in section 3.2.1 - is it OK like this?
4463 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4465 SDCC source changes:
4466 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4500 UPPER for immediate operands,
4501 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4503 * src/pic16/peeph.def: all peepholes with movff are commented out,
4504 because there is a problem in the pcode peep optimizer,
4505 * src/pic16/ralloc.c: the register allocator can now reuse local

4598 include information about variables allocated to the overlay
4601 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4603 * as/mcs51/lkmain.c: Help about -Y option

4615 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4617 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4618 (default behaviour).
4620 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4622 A python script to validate compiler diagnostic messages. It can be
4623 used to verify that sdcc complains about bad c source code and
4624 gives a good location of the error.
4625 * support/valdiag/Makefile,
4626 * support/valdiag/valdiag.py,
4627 * support/valdiag/tests/*

4644 Bug reported from Jesus Calvino-Fraga
4646 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4648 * sdcc.spec: updated
4649 * device/include/Makefile.in: don't install CVS directories
4650 * device/lib/Makefile.in: added removal of CVS directories after install
4651 * doc/Makefile: fixed install, added local_icons
4652 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4653 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4654 * src/ds390/gen.c (genRightShift): fixed bug #870788
4655 * src/SDCCast.c (decorateType): fixed bug #870781
4657 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4659 PIC16 port related changes:
4660 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4661 added variable stackPos,
4663 * gen.c: genCall, assignResultValue: added support for
4664 pushing/retrieving function parameters to/from stack,
4665 genFunction,genEndFunction: setup stack frame for the
4667 genAddrOf: will be changed according to bug 863624
4669 * added files genutils.c and genutils.h which contain gen*
4670 debugged and optimised functions extracted from gen.c
4672 * glue.c: added variable 'externs' which holds extern symbols,
4673 pic16emitRegularMap: is modified to properly handle relocatable
4674 symbols under the new scheme,
4675 pic16createInterruptVect: is modified
4676 pic16printPublics: is modified to emit 'global' assembler directives,
4677 added pic16_printExterns to print extern symbols,
4678 pic16glue: initializes stack/frame pointer in the beginning of
4679 the assembly output. Temporary hack, will be corrected later,
4680 because gplink yet does not support stack and SDCC does not
4681 yet support a type of crt0.o object to create the final binary.
4683 * Removed many lines that contain 8051 legacy code.
4684 * The code is finally placed under a 'code' directive.
4685 * Added port specific options.
4687 * _process_pragma: simplified since now we do not need *special*
4688 include file to define SFR registers. But a separate header
4689 will be needed. This will be developed later.
4690 * _pic16_parseOptions: added, parses port specific options:
4691 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4692 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4693 --preplace-udata-with=
4695 * _pic16_setDefaultOptions: modified to initialize section names,
4696 but hack is temporarly out of order since it needs improvement.
4697 * _pic16_genAssemblerPreamble: configuration words are emitted by
4698 their address instead of their name. This part is incomplete and
4699 supports only the 18Fxx2 devices. Other devices will emit an error
4700 during assembly since they do not contain the same set of config
4702 * _pic16_genIVT: is modified,
4704 * pcode.c: added definitions for some hardware registers that are needed
4706 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4707 All PCI entries are updated. Now LFSR is supported.
4708 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4709 * added pic16_newpCodeOpLit2 to support instructions with
4710 two literal arguments
4711 * pic16_pCode2str: corrected code that emits assembler instructions
4712 with two literal operands and those that have an access bit modifier
4713 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4714 this fixes a bug which caused some labels to be lost, when an
4715 assembler directive was added, i.e. banksel,
4716 * pic16_FixRegisterBanking: improved logic that causes the insertion
4718 * InlineFunction: functions that are called once, are not any more
4719 inlined. This can be a port option in the future,
4721 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4723 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4724 hold the corresponding uninitialized symbols,
4725 * pic16_allocProcessorRegister: registers have explicit marked the
4727 * pic16_allocInternalRegister: registers are explicit marked as
4729 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4730 processing list, so bit registers were lost,
4733 * ralloc.h: added field 'accessBank' and original symbol operand
4734 in register definition,
4735 * removed the field isMapped from register definition,
4737 ** Several functions have been removed from various sources:
4738 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4739 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4740 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4741 pic16_assignRelocatableRegisters
4743 ** others have been introduced:
4744 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4745 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4747 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4749 * support/scripts/inc2h.pl: changed definition of BIT_AT
4750 to emit 'sbit at' instead of 'bit at'. This was a request.
4752 PIC16 port related preliminary changes:
4753 * gen.c: prefixed function popRegFromString with
4754 pic16_ and all references to it corrected
4755 * pcode.c: all pic16_pc_* hardware registers prefixed
4756 with underscore (_),
4757 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4758 * ralloc.c: newReg(): when register is REG_SFR then
4759 set address to rIdx,
4760 pic16_allocProcessorRegister(): marks register wasUsed=0
4761 pic16_writeUsedRegs(): added a call to assign processor
4762 registers via pic16_assignFixedRegisters
4764 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4766 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4767 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4768 variables in unused register banks. Also the SSEG is placed
4769 wherever there is enough space for it, and IDATA can be anywhere
4770 in internal RAM. For now compile using -Wl-Y[stack_size].
4771 The mem file is different for this option as well, since it
4772 makes no sense of talking about DSEG lenght.
4774 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4776 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4777 in certain cases, e.g. when ROM assignment, patch provided
4778 from Albert den Haan.
4780 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4923 * src/mcs51/peephole.def,
4924 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4925 (allows non-interrupt and interrupt code to safely compete for a resource

5803 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5804 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5805 type for bits was changed. It resulted in bit variables becoming

5823 A few small changes that speed up the peephole optimizer.
5827 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5829 Try to make the peephole optimizer smarter by maintaining
5830 an association between the assembly source code and the
5831 iCodes that originated them. Put this information to use
5832 with a new peephole rule condition "notVolatile" so that
5833 the rules can be aggressive yet still safe.
5838 * src/mcs51/peeph.def
5840 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5844 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5845 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5846 if the left or right operand symbols have the accuse flag set.
5848 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5850 Changed the type of the result of the ! (NOT) operator to char;
5851 previously it returned the same type as the source. This allows
5852 us to eliminate all the genFloatNot functions (all of its target
5853 implementations were very buggy) since !float can use the same
5856 * src/SDCCicode.c (ast2iCode): ! returns char

5865 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5866 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5867 during interrupts. Ensure WSAVE is located at a shared bank address.
5868 2. Fixed page selection in some places
5869 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5870 the registers name strings.
5871 4. Fixed "signed / unsigned compare" compiler warnings.
5872 5. The PIC port manages its own allocation of the general purpose
5873 registers, but makes no attempt to reuse them. As a result when
5874 compiling it soon runs out of general purpose registers. Some
5875 additional code was added to the files pcode.c and device.c to walk
5876 through the function call tree and rename the registers so that they
5886 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5893 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5895 Made bitfield a distinct type from bit so that bitfields
5896 convert as per ANSI C and bits retain their traditional
5897 boolean style behaviour. Implemented bitfield support in
5905 * src/ds390/gen.c: bit v bitfield split
5906 * src/z80/gen.c: New support for bitfields
5907 * support/regression/tests/bitfields.c: reenabled z80,
5910 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5912 Rules 246.x, 247.x relate to bitfields, the others speed up
5913 access to xdata mapped I/O devices.
5915 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5917 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5919 Cleaned up genPackBits and genUnpackBits and added two helper

5929 Fixed bug #748310 (pointer to function type mishandled when the
5930 function name is omitted). Also fixed a SIGSEGV when a function
5931 attribute (reentrant, etc) is used on a non-function or on a
5932 function but misplaced before the parameter list.
5934 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

5961 Made the constant following the "interrupt" keyword optional. If
5962 omitted, the function will not automatically be given an entry
5963 in the interrupt vector table (similar to #pragma NOIV, but
5964 less syntacticly kludgy). The interrupt number is also now
5965 range checked. Also fixed a bug in the high order bit example

6496 messages from optionsTable when a port is not configured, added
6497 support for the PIc16 port in the ports table, when executing
6498 the compiler with no port specified on command line, a default
6499 port is selected with the new macro DEFAULT_PORT which is
6500 defined in port.h, in setDefaultOptions() linkOptions is removed
6501 from initialization assignment, since now it is a set,
6502 parseCmdLine uses setParseWithComma for linkOptions, in
6503 linkEdit() linkOptions are accessed with new function indexSet()
6504 which returns the i'th item of a set variable. See SDCCset.c, in
6505 linkEdit() when calling buildCmdLine(), added linkOptions as
6506 last argument. Now users can pass arguments to gplink via the
6507 -Wl option, main() uses pic16glue() to glue up pic16 programs

6521 gpasm complaining and test the linkage with gplink, _linkCmd and
6522 _asmCmd changed to be more gplink and gpasm friendly

7571 2003-01-04 <johan AT balder>
7573 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7575 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7576 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7578 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7585 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7586 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7588 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7589 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7591 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7593 * in \sdcc\as\mcs51\ changed these files in order to create an
7594 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7595 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7596 following files to include the previous two files: aslink.dsp,
7597 Makefile.aslink, Makefile.bcc, and Makefile.in.
7599 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7600 .adb instead of .cdb
7602 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7604 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7605 value from option --iram-size.
7607 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7609 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7612 2002-09-18 <wiml AT hhhh.org>
7614 * SDCClrange.h: exposed setFromRange() and setToRange()
7615 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7616 packRegsForAccUse() (bug 542397)
7617 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7618 multiple times and emitting the fetch operations more than once
7619 added aopGetUsesAcc() function to allow binary operators to
7620 fetch their operands in the correct order; made genMinus() emit
7621 compact code for X = LITERAL - Y
7623 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7624 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7625 sprintf() in line 1267.
7627 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7628 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7631 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7632 Changes to aslink (All the changes are marked with 'JCF'):
7634 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7637 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7638 area BSEG. Also moves, if possible, the DATA area down into the internal
7639 ram so more space is available.
7641 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7644 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7645 not bytes. Function summary() which creates a memory usage summary
7646 file with extension .mem. Reports of overlaping stack and small stack
7647 size. If the space for the stack is less than 16 bytes aslink trows a
7650 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7651 the 8051. Option 'y' for memory summary output file.
7653 Changes to sdcc (All the changes are marked with 'JCF'):
7655 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7657 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7658 overlaying area for it (uses RegBankUsed[4]).
7660 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7661 bank zero as used by default. By default aslink locates the stack
7662 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7663 the creation of the .mem file. Delegates the allocation of data area
7664 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7665 the begining of the stack area to aslink.
7667 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7668 glue() in SDCCglue.c creates an area for it.
7670 2002-09-03 Borut Razem <borut.razem AT siol.net>
7671 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7672 sdcc/src/pic/glue.c:
7673 introduced atexit() handler for teporay files removal in case of
7674 errors, assertions, ...
7676 2002-08-29 Borut Razem <borut.razem AT siol.net>
7677 * sdcc/support/cpp2/auto-host_vc_in.h:
7678 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7679 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7680 Maybe there is a similar problem with BORLANDC? It should be checked!
7682 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7683 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7684 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7685 was not executed, and the compiler (cl) launched a warning:
7686 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7688 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7689 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7691 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7692 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7694 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7695 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7696 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7697 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7698 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7699 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7700 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7701 - added Release configuration in VS projects
7702 - review of compiler an linker options
7703 - VC .exe files are generated in bin_vc directory, not to interfere
7704 with binaries generated from other projects (cygwin, mingw, bcc ...)
7706 * sdcc/src/yacc.dsp: added
7708 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7709 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7710 and insert the version number definitions from .version
7712 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7714 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7715 added - genarate auto-host.h using auto-host_vc_in.h as template
7718 removed from CVS, generated automatically
7720 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7721 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7723 2002-08-11 Borut Razem <borut.razem AT siol.net>
7724 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7726 2002-08-10 Borut Razem <borut.razem AT siol.net>
7727 * src/SDCCmain.c (main):
7728 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7729 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7730 The consequence was that some temporary files were not removed.
7733 unification of code in functions tempfilename() and tempfile():
7734 function tempnam() is defined in Visual Studio 6.0 and .NET
7736 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7738 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7739 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7740 - removed compiler command line option /WX: Treats all warnings as errors
7741 - update a list of source files, included into the project
7743 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7744 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7745 changed project type to Generic Project so that can be correcly converted to VS.NET project
7747 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7749 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7751 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7753 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7754 added return 0 statements after assert() to make compiler happy
7756 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7757 added newline in the def file to keep MSC compiler satisfied
7759 * sdcc/src/z80/gen.c:
7760 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7761 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7762 - solved MSC error in function aopDump()
7764 * sdcc_vc.h: define PREFIX as "\\sdcc"
7766 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7767 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7769 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7770 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7771 - Rewrote the register banking algorithm.
7772 - Added pCode live-range analysis to registers (for now, only non-used and
7773 singly-used registers optimized away)
7775 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7777 * 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.
7779 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7780 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

7798 * src/z80/peeph.def: Added transpose redundent load rule.
7800 * src/z80/main.c: Added force callee saves for jaune.
7802 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7804 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7806 2002-03-28 Johan Knol <johan AT balder>
7808 * src/SDCCval.c: fixed bug #532436
7810 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7812 Added "char *Processor" field to the port structure.
7815 Added -p option. Allows port dependent processor to be specified.
7818 Initialized the new field char *Processor field to NULL in all ports
7821 Compiler generated registers for interrupt context saving
7822 were not getting allocated.
7824 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7827 Fixed left shift. Will promote the left side of a left shift
7828 if a) left shifting more than size of operand or b) when assigned
7829 to something size > size of left side
7831 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7833 tons of changes. Register allocation has been
7834 rewritten. Added customization for the various PICs. Flow
7835 analysis is restructured. ...
7841 Added. device.c is a PIC port hack to accomodate variations
7844 2002-03-13 Michael Hope <michaelh AT vroom>
7846 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7848 2002-03-04 johanknol <johanknol AT manik>
7850 * /src/SDCCval.c: fixed
7852 const unsigned char arr[][2] = { { 0, 1 } };
7853 t18.c:1: error: Initializer element is not constant
7855 2002-03-04 bela <bela AT manik>
7857 * /device/include/mcs51reg.h:
7858 ds89c420 register definition update
7860 2002-03-03 <johan AT FRIJA>
