470 * (genCmp): adapted to new genSkipc semantics
471 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
472 on rIfx (genCmp was broken)
474 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
476 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
477 * src/z80/main.c (_keywords[]),
478 * src/SDCCglobal.h (struct options),
480 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
481 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
482 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
483 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
484 always available in leading double underscore form. The C99 support is
485 mostly missing, but it's a start.
486 * support/regression/tests/bug-227710.c: fixed nonconforming use of
487 reserved identifier "__data".
489 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

565 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
567 * device/lib/printf_large.c: removed inline assembly for portability and
568 readability. Use printf_fast if speed or size are more important.
569 * src/pic16/gen.c: removed conditions around use of DEBUGpc
570 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
572 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
574 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
575 prevent compiler warning
577 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
579 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
580 moved to level 0 and declared as static. Also they are explicit
581 placed in access bank. This was necessery because some times they
582 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
583 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
584 optimizations. Currently only compare to unsigned char is implemented,
585 * src/pic16/gen.c: added fReturnIdx array,
586 * (struct resolvedIfx) is moved to gen.h and made public,
587 * (struct _G): added sregsAlloc and sregsAllocSet fields,
588 * (aopForSym): added an optimization to directly store in stack of
589 the operand of a SEND iCode,
590 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
591 but as registers instead (AOP_REG) using the fReturnIdx array,
592 * (pic16_freeAsmop): remove the freed register from the
594 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
596 * (pic16_popGetTempRegCond): changed function prototype, now
597 function takes also a bitVector argument v which holds the current
598 set of registers that are allocated for stack access by aopForSym,
599 registers allocated in aopForSym for accessing stack symbols are not
600 any more part of the functions usedRegs field,
601 * (genCall): some times aopOp is called for a stack variable to be
602 send, aopForSym might perform the push, if this is true make sure
603 that genCall doesn't push the variable twice by testing _G.resDirect,
604 * (genFunction): changed testing for unspecified interrupt number
605 from 256 to INTNO_UNSPEC,
606 * modified selection scheme of frame pointer generation. Previously
607 if function did use local registers a frame pointer was generated,
608 now a frame pointer is generated only if function has arguments
609 (that need PLUSW2 register access), or has stack arguments, or the
610 compiler is not instructed to omit the frame pointer,
611 * (genEndFunction): before restoring local registers that were saved
612 in the function preamble, also restore the registers that *might*
613 have been allocated for stack access,
614 * (genRet): removed some old comments,
615 * (genCmp, the active (RN's) version): added a call to the
616 pic16_genCmp_special function to perform the compare with a more
617 robust and optimized way,
618 * (genInline): a feature has been added in inline code generation,
619 which allows a wildcard variable substitution when writing inline
620 assembly. Code is incomplete and experimental therefore undocumented,
621 * (genCast): changed order of aopOp for result and right to allow
622 aopForSym to directly load the result if possible,
623 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
624 perform an optimized compare on some selected special occasions,
625 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
626 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
627 generate an IVT any more,
628 * src/pic16/main.c (pic16_optionsTable): added command line option
630 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
631 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
633 * src/pic16/NOTES: Raphael Neider added in list of active developers
634 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
635 jumptable_end to prevent bug #,
636 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
637 inCond and outCond fields,
638 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
639 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
640 turn off register spilling,
641 * (packRegsForOneUse): synced with other ports' versions although it
642 is not used currently,
643 * (pic16_packRegisters): added an optimization while reading
644 structure bitfields, some registers may be saved (malloc code is
645 decreased by 80 bytes)
647 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
649 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
650 left is a bitfield, if yes, then don't optimize assignment. Perhaps
651 this can be optimized more?
653 2005-03-10 Raphael Neider <rneider AT web.de>
655 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
656 genNearPointerGet): (hopefully) fixed access to bitfields via
657 pointers (p->bitN = x; and x = p->bitN; failed)

4375 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4377 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4378 loaded with the linker search paths (-L arguments) and the libraries
4379 to be linked with the current source (-l arguments). Changes
4380 currently will affect only the pic16 port.
4381 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4382 include path the port specific paths and port specific libraries,
4383 * gplink command now contains the $3 argument,
4384 * src/pic16/device.h,
4385 * src/pic16/device.c,: structure PIC_device is made public and
4386 renamed to PIC16_device, the same for variable Pics which is renamed

4401 Documenting changes from previous commits.
4402 * configure.in (version 1.56),
4403 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4404 when generating output files to configure the pic16 library,
4405 but now I've commented it out, since gputils aren't installed in the
4406 SF compile farm, so library won't compile
4408 * device/lib/Makefile.in (version 1.56): initially I've added in
4409 target 'all' the prerequestive 'model-pic16' so it compiled the
4410 pic16 library, but now I've commented it out for the same reasons
4412 * added targets 'model-pic16' and 'objects-pic16' to compile the
4414 * added target 'port-specific-objects-pic16' to handle the
4415 generated libraries and copy them into the build/ directory
4416 * added target 'clean-intermediate-pic16' to clean intermediate
4417 files into pic16 directory
4418 * in target 'installdirs' added line to create directory pic16 in
4419 the installation path
4421 * device/include/Makefile.in (version 1.11): in target 'install'
4422 added lines to copy all header files to installation path,
4423 * in target 'installdirs' added line create directory for pic16
4424 headers in the installation path

4439 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4440 option so that it actually works. Made it specific to the z80, since
4441 the gbz80 doesn't have these kinds of I/O ports.
4443 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4469 via literal number. The symbol is placed in the corresponding
4470 position of the data ram
4471 * (pic16_dump_section): relocatable and absolute uninitialized
4472 data are now emitted in sorted order to reduce section naming,
4473 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4474 weren't marked as being in the access bank,
4476 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4478 Added portion of GNU PIC Library under the directory
4479 device/include/pic16 and device/lib/pic16. These files

4511 all over. Telling LaTeX to be less strict with word spacing
4512 to better keep the right margin. Changed some notes about
4513 maintainance of the ports in section 3.2.1 - is it OK like this?
4515 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4555 * src/pic16/peeph.def: all peepholes with movff are commented out,
4556 because there is a problem in the pcode peep optimizer,
4557 * src/pic16/ralloc.c: the register allocator can now reuse local

4650 include information about variables allocated to the overlay
4653 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4655 * as/mcs51/lkmain.c: Help about -Y option

4667 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4669 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4670 (default behaviour).
4672 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4674 A python script to validate compiler diagnostic messages. It can be
4675 used to verify that sdcc complains about bad c source code and
4676 gives a good location of the error.
4677 * support/valdiag/Makefile,
4678 * support/valdiag/valdiag.py,
4679 * support/valdiag/tests/*
4681 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4695 around the header file.
4696 Bug reported from Jesus Calvino-Fraga
4698 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4700 * sdcc.spec: updated
4701 * device/include/Makefile.in: don't install CVS directories
4702 * device/lib/Makefile.in: added removal of CVS directories after install
4703 * doc/Makefile: fixed install, added local_icons
4704 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4705 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4706 * src/ds390/gen.c (genRightShift): fixed bug #870788
4707 * src/SDCCast.c (decorateType): fixed bug #870781
4709 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4711 PIC16 port related changes:
4712 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4713 added variable stackPos,
4715 * gen.c: genCall, assignResultValue: added support for
4716 pushing/retrieving function parameters to/from stack,
4717 genFunction,genEndFunction: setup stack frame for the
4719 genAddrOf: will be changed according to bug 863624
4721 * added files genutils.c and genutils.h which contain gen*
4722 debugged and optimised functions extracted from gen.c
4724 * glue.c: added variable 'externs' which holds extern symbols,
4725 pic16emitRegularMap: is modified to properly handle relocatable
4726 symbols under the new scheme,
4727 pic16createInterruptVect: is modified
4728 pic16printPublics: is modified to emit 'global' assembler directives,
4729 added pic16_printExterns to print extern symbols,
4730 pic16glue: initializes stack/frame pointer in the beginning of
4731 the assembly output. Temporary hack, will be corrected later,
4732 because gplink yet does not support stack and SDCC does not
4733 yet support a type of crt0.o object to create the final binary.
4735 * Removed many lines that contain 8051 legacy code.
4736 * The code is finally placed under a 'code' directive.
4737 * Added port specific options.
4739 * _process_pragma: simplified since now we do not need *special*
4740 include file to define SFR registers. But a separate header
4741 will be needed. This will be developed later.
4742 * _pic16_parseOptions: added, parses port specific options:
4743 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4744 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4745 --preplace-udata-with=
4747 * _pic16_setDefaultOptions: modified to initialize section names,
4748 but hack is temporarly out of order since it needs improvement.
4749 * _pic16_genAssemblerPreamble: configuration words are emitted by
4750 their address instead of their name. This part is incomplete and
4751 supports only the 18Fxx2 devices. Other devices will emit an error
4752 during assembly since they do not contain the same set of config
4754 * _pic16_genIVT: is modified,
4756 * pcode.c: added definitions for some hardware registers that are needed
4758 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4759 All PCI entries are updated. Now LFSR is supported.
4760 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4761 * added pic16_newpCodeOpLit2 to support instructions with
4762 two literal arguments
4763 * pic16_pCode2str: corrected code that emits assembler instructions
4764 with two literal operands and those that have an access bit modifier
4765 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4766 this fixes a bug which caused some labels to be lost, when an
4767 assembler directive was added, i.e. banksel,
4768 * pic16_FixRegisterBanking: improved logic that causes the insertion
4770 * InlineFunction: functions that are called once, are not any more
4771 inlined. This can be a port option in the future,
4773 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4775 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4776 hold the corresponding uninitialized symbols,
4777 * pic16_allocProcessorRegister: registers have explicit marked the
4779 * pic16_allocInternalRegister: registers are explicit marked as
4781 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4782 processing list, so bit registers were lost,
4785 * ralloc.h: added field 'accessBank' and original symbol operand
4786 in register definition,
4787 * removed the field isMapped from register definition,
4789 ** Several functions have been removed from various sources:
4790 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4791 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4792 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4793 pic16_assignRelocatableRegisters
4795 ** others have been introduced:
4796 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4797 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4799 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4801 * support/scripts/inc2h.pl: changed definition of BIT_AT
4802 to emit 'sbit at' instead of 'bit at'. This was a request.
4804 PIC16 port related preliminary changes:
4805 * gen.c: prefixed function popRegFromString with
4806 pic16_ and all references to it corrected
4807 * pcode.c: all pic16_pc_* hardware registers prefixed
4808 with underscore (_),
4809 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4810 * ralloc.c: newReg(): when register is REG_SFR then
4811 set address to rIdx,
4812 pic16_allocProcessorRegister(): marks register wasUsed=0
4813 pic16_writeUsedRegs(): added a call to assign processor
4814 registers via pic16_assignFixedRegisters
4816 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4818 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4819 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4820 variables in unused register banks. Also the SSEG is placed
4821 wherever there is enough space for it, and IDATA can be anywhere
4822 in internal RAM. For now compile using -Wl-Y[stack_size].
4823 The mem file is different for this option as well, since it
4824 makes no sense of talking about DSEG lenght.
4826 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4828 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4829 in certain cases, e.g. when ROM assignment, patch provided
4830 from Albert den Haan.
4832 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5855 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5856 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5857 type for bits was changed. It resulted in bit variables becoming

5875 A few small changes that speed up the peephole optimizer.
5879 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5881 Try to make the peephole optimizer smarter by maintaining
5882 an association between the assembly source code and the
5883 iCodes that originated them. Put this information to use
5884 with a new peephole rule condition "notVolatile" so that
5885 the rules can be aggressive yet still safe.
5890 * src/mcs51/peeph.def
5892 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5896 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5897 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5898 if the left or right operand symbols have the accuse flag set.
5900 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5902 Changed the type of the result of the ! (NOT) operator to char;
5903 previously it returned the same type as the source. This allows
5904 us to eliminate all the genFloatNot functions (all of its target
5905 implementations were very buggy) since !float can use the same

5917 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5918 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5919 during interrupts. Ensure WSAVE is located at a shared bank address.
5920 2. Fixed page selection in some places
5921 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5922 the registers name strings.
5923 4. Fixed "signed / unsigned compare" compiler warnings.
5924 5. The PIC port manages its own allocation of the general purpose
5925 registers, but makes no attempt to reuse them. As a result when
5926 compiling it soon runs out of general purpose registers. Some
5927 additional code was added to the files pcode.c and device.c to walk
5928 through the function call tree and rename the registers so that they
5938 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5945 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5947 Made bitfield a distinct type from bit so that bitfields
5948 convert as per ANSI C and bits retain their traditional
5949 boolean style behaviour. Implemented bitfield support in

5965 access to xdata mapped I/O devices.
5967 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5969 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5971 Cleaned up genPackBits and genUnpackBits and added two helper
5972 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5973 for literal assignments in genPackBits (thanks to Frieder for
5979 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5981 Fixed bug #748310 (pointer to function type mishandled when the
5982 function name is omitted). Also fixed a SIGSEGV when a function
5983 attribute (reentrant, etc) is used on a non-function or on a
5984 function but misplaced before the parameter list.

6013 Made the constant following the "interrupt" keyword optional. If
6014 omitted, the function will not automatically be given an entry
6015 in the interrupt vector table (similar to #pragma NOIV, but
6016 less syntacticly kludgy). The interrupt number is also now
6017 range checked. Also fixed a bug in the high order bit example

6038 unsigned, but are signed by default
6039 * src/SDCCval.c (constVal): rearranged
6040 * src/SDCCval.c (valMod): preliminary fix
6041 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6532 * doc/sdccman.lyx: fixed bug 739745
6533 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
6535 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6537 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6538 it can be defined with CFLAGS when running configure
6539 * src/SDCCmain.c: fixed compiling + linking with object files
6541 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6543 * configure.in: configure for pic16 port,
6544 added --disable-pic16-port
6545 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6546 * src/SDCCmain.c: linkOptions is changed to set *,
6547 added if/endif conditional macros to remove options help
6548 messages from optionsTable when a port is not configured, added
6549 support for the PIc16 port in the ports table, when executing
6550 the compiler with no port specified on command line, a default
6551 port is selected with the new macro DEFAULT_PORT which is
6552 defined in port.h, in setDefaultOptions() linkOptions is removed
6553 from initialization assignment, since now it is a set,
6554 parseCmdLine uses setParseWithComma for linkOptions, in
6555 linkEdit() linkOptions are accessed with new function indexSet()
6556 which returns the i'th item of a set variable. See SDCCset.c, in
6557 linkEdit() when calling buildCmdLine(), added linkOptions as
6558 last argument. Now users can pass arguments to gplink via the
6559 -Wl option, main() uses pic16glue() to glue up pic16 programs
6560 * src/SDCCpeeph.c: various changes to support pic16
6561 * src/SDCCset.c: added function void *indexSet(set *, int) to

6571 * src/pic16/glue.c: commented out some error producing lines
6572 * src/pic16/main.c: __config directives are commented out to stop
6573 gpasm complaining and test the linkage with gplink, _linkCmd and
6574 _asmCmd changed to be more gplink and gpasm friendly
6575 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6576 produced an error when parsed, peep rule 12 is added to utilize
6577 movff, but it is commented out since the pCode does not support
6578 yet a command with 2 address arguments
6580 2003-05-18 <johan AT balder>
6582 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6609 2003-05-11 Borut Razem <borut.razem AT siol.net>
6611 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6612 the path of bin directory, so that PATH is the only env. variable, which has to be set
6613 in case of standard installation.

7600 2003-01-07 <johan AT balder>
7602 * src/SDCCast.c (decorateType): fixed bug #600035

7617 * src/SDCCicode.c: fixed array add
7619 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7620 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7621 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7623 2003-01-04 <johan AT balder>
7625 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7627 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7628 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7630 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7631 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7637 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7638 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7640 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7641 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7643 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7645 * in \sdcc\as\mcs51\ changed these files in order to create an
7646 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7647 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7648 following files to include the previous two files: aslink.dsp,
7649 Makefile.aslink, Makefile.bcc, and Makefile.in.
7651 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7652 .adb instead of .cdb
7654 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7656 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7657 value from option --iram-size.
7659 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7661 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7664 2002-09-18 <wiml AT hhhh.org>
7666 * SDCClrange.h: exposed setFromRange() and setToRange()
7667 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7668 packRegsForAccUse() (bug 542397)
7669 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7670 multiple times and emitting the fetch operations more than once
7671 added aopGetUsesAcc() function to allow binary operators to
7672 fetch their operands in the correct order; made genMinus() emit
7673 compact code for X = LITERAL - Y
7675 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7676 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7677 sprintf() in line 1267.
7679 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7680 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7683 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7684 Changes to aslink (All the changes are marked with 'JCF'):
7686 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7689 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7690 area BSEG. Also moves, if possible, the DATA area down into the internal
7691 ram so more space is available.
7693 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7696 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7697 not bytes. Function summary() which creates a memory usage summary
7698 file with extension .mem. Reports of overlaping stack and small stack
7699 size. If the space for the stack is less than 16 bytes aslink trows a
7702 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7703 the 8051. Option 'y' for memory summary output file.
7705 Changes to sdcc (All the changes are marked with 'JCF'):
7707 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7709 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7710 overlaying area for it (uses RegBankUsed[4]).
7712 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7713 bank zero as used by default. By default aslink locates the stack
7714 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7715 the creation of the .mem file. Delegates the allocation of data area
7716 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7717 the begining of the stack area to aslink.
7719 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7720 glue() in SDCCglue.c creates an area for it.
7722 2002-09-03 Borut Razem <borut.razem AT siol.net>
7723 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7724 sdcc/src/pic/glue.c:
7725 introduced atexit() handler for teporay files removal in case of
7726 errors, assertions, ...
7728 2002-08-29 Borut Razem <borut.razem AT siol.net>
7729 * sdcc/support/cpp2/auto-host_vc_in.h:
7730 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7731 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7732 Maybe there is a similar problem with BORLANDC? It should be checked!
7734 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7735 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7736 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7737 was not executed, and the compiler (cl) launched a warning:
7738 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7740 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7741 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7743 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7744 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7746 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7747 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7748 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7749 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7750 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7751 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7752 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7753 - added Release configuration in VS projects
7754 - review of compiler an linker options
7755 - VC .exe files are generated in bin_vc directory, not to interfere
7756 with binaries generated from other projects (cygwin, mingw, bcc ...)
7758 * sdcc/src/yacc.dsp: added
7760 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7761 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7762 and insert the version number definitions from .version
7764 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7766 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7767 added - genarate auto-host.h using auto-host_vc_in.h as template
7770 removed from CVS, generated automatically
7772 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7773 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7775 2002-08-11 Borut Razem <borut.razem AT siol.net>
7776 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7778 2002-08-10 Borut Razem <borut.razem AT siol.net>
7779 * src/SDCCmain.c (main):
7780 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7781 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7782 The consequence was that some temporary files were not removed.
7785 unification of code in functions tempfilename() and tempfile():
7786 function tempnam() is defined in Visual Studio 6.0 and .NET
7788 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7790 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7791 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7792 - removed compiler command line option /WX: Treats all warnings as errors
7793 - update a list of source files, included into the project
7795 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7796 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7797 changed project type to Generic Project so that can be correcly converted to VS.NET project
7799 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7801 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7803 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7805 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7806 added return 0 statements after assert() to make compiler happy
7808 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7809 added newline in the def file to keep MSC compiler satisfied
7811 * sdcc/src/z80/gen.c:
7812 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7813 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7814 - solved MSC error in function aopDump()
7816 * sdcc_vc.h: define PREFIX as "\\sdcc"
7818 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7819 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7821 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7822 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7823 - Rewrote the register banking algorithm.
7824 - Added pCode live-range analysis to registers (for now, only non-used and
7825 singly-used registers optimized away)
7827 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7829 * 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.
7831 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7832 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7834 2002-04-22 Michael Hope <michaelh AT vroom>
7836 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
