488 * (genCmp): adapted to new genSkipc semantics
489 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
490 on rIfx (genCmp was broken)
492 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
494 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
495 * src/z80/main.c (_keywords[]),
496 * src/SDCCglobal.h (struct options),
498 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
499 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
500 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
501 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
502 always available in leading double underscore form. The C99 support is
503 mostly missing, but it's a start.
504 * support/regression/tests/bug-227710.c: fixed nonconforming use of
505 reserved identifier "__data".
507 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

553 2005-03-20 Borut Razem <borut.razem AT siol.net>
555 * support/scripts/inc2h.pl: WIN32 port

581 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
583 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
585 * device/lib/printf_large.c: removed inline assembly for portability and
586 readability. Use printf_fast if speed or size are more important.
587 * src/pic16/gen.c: removed conditions around use of DEBUGpc
588 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
590 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
592 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
593 prevent compiler warning
595 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
597 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
598 moved to level 0 and declared as static. Also they are explicit
599 placed in access bank. This was necessery because some times they
600 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
601 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
602 optimizations. Currently only compare to unsigned char is implemented,
603 * src/pic16/gen.c: added fReturnIdx array,
604 * (struct resolvedIfx) is moved to gen.h and made public,
605 * (struct _G): added sregsAlloc and sregsAllocSet fields,
606 * (aopForSym): added an optimization to directly store in stack of
607 the operand of a SEND iCode,
608 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
609 but as registers instead (AOP_REG) using the fReturnIdx array,
610 * (pic16_freeAsmop): remove the freed register from the
612 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
614 * (pic16_popGetTempRegCond): changed function prototype, now
615 function takes also a bitVector argument v which holds the current
616 set of registers that are allocated for stack access by aopForSym,
617 registers allocated in aopForSym for accessing stack symbols are not
618 any more part of the functions usedRegs field,
619 * (genCall): some times aopOp is called for a stack variable to be
620 send, aopForSym might perform the push, if this is true make sure
621 that genCall doesn't push the variable twice by testing _G.resDirect,
622 * (genFunction): changed testing for unspecified interrupt number
623 from 256 to INTNO_UNSPEC,
624 * modified selection scheme of frame pointer generation. Previously
625 if function did use local registers a frame pointer was generated,
626 now a frame pointer is generated only if function has arguments
627 (that need PLUSW2 register access), or has stack arguments, or the
628 compiler is not instructed to omit the frame pointer,
629 * (genEndFunction): before restoring local registers that were saved
630 in the function preamble, also restore the registers that *might*
631 have been allocated for stack access,
632 * (genRet): removed some old comments,
633 * (genCmp, the active (RN's) version): added a call to the
634 pic16_genCmp_special function to perform the compare with a more
635 robust and optimized way,
636 * (genInline): a feature has been added in inline code generation,
637 which allows a wildcard variable substitution when writing inline
638 assembly. Code is incomplete and experimental therefore undocumented,
639 * (genCast): changed order of aopOp for result and right to allow
640 aopForSym to directly load the result if possible,
641 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
642 perform an optimized compare on some selected special occasions,
643 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
644 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
645 generate an IVT any more,
646 * src/pic16/main.c (pic16_optionsTable): added command line option
648 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
649 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
651 * src/pic16/NOTES: Raphael Neider added in list of active developers
652 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
653 jumptable_end to prevent bug #,
654 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
655 inCond and outCond fields,
656 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
657 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
658 turn off register spilling,
659 * (packRegsForOneUse): synced with other ports' versions although it
660 is not used currently,
661 * (pic16_packRegisters): added an optimization while reading
662 structure bitfields, some registers may be saved (malloc code is
663 decreased by 80 bytes)
665 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
667 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
668 left is a bitfield, if yes, then don't optimize assignment. Perhaps
669 this can be optimized more?
671 2005-03-10 Raphael Neider <rneider AT web.de>
673 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
674 genNearPointerGet): (hopefully) fixed access to bitfields via
675 pointers (p->bitN = x; and x = p->bitN; failed)
677 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
679 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

866 this might fix SIGSEGVs on MinGW...
867 * src/SDCCopt.c (killDeadCode): restored original behaviour
868 (volatile operands might get thrown away though)
870 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1347 * added libc directory. The current version of LibC contains string
1348 functions, ctype functions and macros and some functions of the
1349 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1350 be extensively tested in the future. Standard disclaimer here.
1351 Library is not automatically build yet. But one can build it by
1352 invoking 'make' inside the libc directory.

1365 special compare&skip instructions. Initial tests fail some times
1366 with variables grater than 1 byte in size, so new code is disabled,
1367 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1369 * (genCast): began a fix to optimize the casting of a bit to another
1370 bit, now assigning a bitfield to another bitfield will fail, sorry,

1378 * (isBankInstruction): modified to return 0 for no banking instruction,
1379 and 1 for banking instruction,
1380 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1381 caused stop processing pCodes after a inline assembly block,
1382 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1384 registers when it shouldn't,
1385 * src/pic16/ralloc.c (allocReg): add preliminary support for
1386 supporting a limited set of temporary registers,

4393 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4395 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4396 loaded with the linker search paths (-L arguments) and the libraries
4397 to be linked with the current source (-l arguments). Changes
4398 currently will affect only the pic16 port.
4399 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4400 include path the port specific paths and port specific libraries,
4401 * gplink command now contains the $3 argument,
4402 * src/pic16/device.h,
4403 * src/pic16/device.c,: structure PIC_device is made public and
4404 renamed to PIC16_device, the same for variable Pics which is renamed

4419 Documenting changes from previous commits.
4420 * configure.in (version 1.56),
4421 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4422 when generating output files to configure the pic16 library,
4423 but now I've commented it out, since gputils aren't installed in the
4424 SF compile farm, so library won't compile
4426 * device/lib/Makefile.in (version 1.56): initially I've added in
4427 target 'all' the prerequestive 'model-pic16' so it compiled the
4428 pic16 library, but now I've commented it out for the same reasons
4430 * added targets 'model-pic16' and 'objects-pic16' to compile the
4432 * added target 'port-specific-objects-pic16' to handle the
4433 generated libraries and copy them into the build/ directory
4434 * added target 'clean-intermediate-pic16' to clean intermediate
4435 files into pic16 directory
4436 * in target 'installdirs' added line to create directory pic16 in
4437 the installation path
4439 * device/include/Makefile.in (version 1.11): in target 'install'
4440 added lines to copy all header files to installation path,

4487 via literal number. The symbol is placed in the corresponding
4488 position of the data ram
4489 * (pic16_dump_section): relocatable and absolute uninitialized
4490 data are now emitted in sorted order to reduce section naming,
4491 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4492 weren't marked as being in the access bank,
4494 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4496 Added portion of GNU PIC Library under the directory
4497 device/include/pic16 and device/lib/pic16. These files
4498 contain the declarations of SFRs for the PIC18Fxx2 devices.

4529 all over. Telling LaTeX to be less strict with word spacing
4530 to better keep the right margin. Changed some notes about
4531 maintainance of the ports in section 3.2.1 - is it OK like this?
4533 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4573 * src/pic16/peeph.def: all peepholes with movff are commented out,
4574 because there is a problem in the pcode peep optimizer,
4575 * src/pic16/ralloc.c: the register allocator can now reuse local

4668 include information about variables allocated to the overlay
4671 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4673 * as/mcs51/lkmain.c: Help about -Y option

4683 LEFT_OP (left shift)
4685 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4687 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4688 (default behaviour).
4690 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4692 A python script to validate compiler diagnostic messages. It can be
4693 used to verify that sdcc complains about bad c source code and
4694 gives a good location of the error.
4695 * support/valdiag/Makefile,
4696 * support/valdiag/valdiag.py,
4697 * support/valdiag/tests/*
4699 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4701 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4712 * src/common.h: added ifndef/define/endif macros
4713 around the header file.
4714 Bug reported from Jesus Calvino-Fraga
4716 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4718 * sdcc.spec: updated
4719 * device/include/Makefile.in: don't install CVS directories
4720 * device/lib/Makefile.in: added removal of CVS directories after install
4721 * doc/Makefile: fixed install, added local_icons
4722 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4723 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4724 * src/ds390/gen.c (genRightShift): fixed bug #870788
4725 * src/SDCCast.c (decorateType): fixed bug #870781
4727 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4729 PIC16 port related changes:
4730 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4731 added variable stackPos,
4733 * gen.c: genCall, assignResultValue: added support for
4734 pushing/retrieving function parameters to/from stack,
4735 genFunction,genEndFunction: setup stack frame for the
4737 genAddrOf: will be changed according to bug 863624
4739 * added files genutils.c and genutils.h which contain gen*
4740 debugged and optimised functions extracted from gen.c
4742 * glue.c: added variable 'externs' which holds extern symbols,
4743 pic16emitRegularMap: is modified to properly handle relocatable
4744 symbols under the new scheme,
4745 pic16createInterruptVect: is modified
4746 pic16printPublics: is modified to emit 'global' assembler directives,
4747 added pic16_printExterns to print extern symbols,
4748 pic16glue: initializes stack/frame pointer in the beginning of
4749 the assembly output. Temporary hack, will be corrected later,
4750 because gplink yet does not support stack and SDCC does not
4751 yet support a type of crt0.o object to create the final binary.
4753 * Removed many lines that contain 8051 legacy code.
4754 * The code is finally placed under a 'code' directive.
4755 * Added port specific options.
4757 * _process_pragma: simplified since now we do not need *special*
4758 include file to define SFR registers. But a separate header
4759 will be needed. This will be developed later.
4760 * _pic16_parseOptions: added, parses port specific options:
4761 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4762 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4763 --preplace-udata-with=
4765 * _pic16_setDefaultOptions: modified to initialize section names,
4766 but hack is temporarly out of order since it needs improvement.
4767 * _pic16_genAssemblerPreamble: configuration words are emitted by
4768 their address instead of their name. This part is incomplete and
4769 supports only the 18Fxx2 devices. Other devices will emit an error
4770 during assembly since they do not contain the same set of config
4772 * _pic16_genIVT: is modified,
4774 * pcode.c: added definitions for some hardware registers that are needed
4776 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4777 All PCI entries are updated. Now LFSR is supported.
4778 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4779 * added pic16_newpCodeOpLit2 to support instructions with
4780 two literal arguments
4781 * pic16_pCode2str: corrected code that emits assembler instructions
4782 with two literal operands and those that have an access bit modifier
4783 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4784 this fixes a bug which caused some labels to be lost, when an
4785 assembler directive was added, i.e. banksel,
4786 * pic16_FixRegisterBanking: improved logic that causes the insertion
4788 * InlineFunction: functions that are called once, are not any more
4789 inlined. This can be a port option in the future,
4791 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4793 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4794 hold the corresponding uninitialized symbols,
4795 * pic16_allocProcessorRegister: registers have explicit marked the
4797 * pic16_allocInternalRegister: registers are explicit marked as
4799 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4800 processing list, so bit registers were lost,
4803 * ralloc.h: added field 'accessBank' and original symbol operand
4804 in register definition,
4805 * removed the field isMapped from register definition,
4807 ** Several functions have been removed from various sources:
4808 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4809 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4810 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4811 pic16_assignRelocatableRegisters
4813 ** others have been introduced:
4814 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4815 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4817 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4819 * support/scripts/inc2h.pl: changed definition of BIT_AT
4820 to emit 'sbit at' instead of 'bit at'. This was a request.
4822 PIC16 port related preliminary changes:
4823 * gen.c: prefixed function popRegFromString with
4824 pic16_ and all references to it corrected
4825 * pcode.c: all pic16_pc_* hardware registers prefixed
4826 with underscore (_),
4827 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4828 * ralloc.c: newReg(): when register is REG_SFR then
4829 set address to rIdx,
4830 pic16_allocProcessorRegister(): marks register wasUsed=0
4831 pic16_writeUsedRegs(): added a call to assign processor
4832 registers via pic16_assignFixedRegisters
4834 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4836 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4837 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4838 variables in unused register banks. Also the SSEG is placed
4839 wherever there is enough space for it, and IDATA can be anywhere
4840 in internal RAM. For now compile using -Wl-Y[stack_size].
4841 The mem file is different for this option as well, since it
4842 makes no sense of talking about DSEG lenght.
4844 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4846 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4847 in certain cases, e.g. when ROM assignment, patch provided
4848 from Albert den Haan.
4850 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5873 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5874 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

5893 A few small changes that speed up the peephole optimizer.
5897 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5899 Try to make the peephole optimizer smarter by maintaining
5900 an association between the assembly source code and the
5901 iCodes that originated them. Put this information to use
5902 with a new peephole rule condition "notVolatile" so that
5903 the rules can be aggressive yet still safe.
5908 * src/mcs51/peeph.def
5910 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5914 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

5916 if the left or right operand symbols have the accuse flag set.
5918 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5920 Changed the type of the result of the ! (NOT) operator to char;
5921 previously it returned the same type as the source. This allows
5922 us to eliminate all the genFloatNot functions (all of its target
5923 implementations were very buggy) since !float can use the same
5926 * src/SDCCicode.c (ast2iCode): ! returns char
5927 * src/mcs51/gen.c (genNot, genNotFloat),
5928 * src/ds390/gen.c (genNot, genNotFloat),
5929 * src/z80/gen.c (genNot, genNotFloat),
5930 * src/pic/gen.c (genNot, genNotFloat),

5938 2. Fixed page selection in some places
5939 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5940 the registers name strings.
5941 4. Fixed "signed / unsigned compare" compiler warnings.
5942 5. The PIC port manages its own allocation of the general purpose
5943 registers, but makes no attempt to reuse them. As a result when
5944 compiling it soon runs out of general purpose registers. Some
5945 additional code was added to the files pcode.c and device.c to walk
5946 through the function call tree and rename the registers so that they
5956 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5963 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5965 Made bitfield a distinct type from bit so that bitfields
5966 convert as per ANSI C and bits retain their traditional
5967 boolean style behaviour. Implemented bitfield support in
5975 * src/ds390/gen.c: bit v bitfield split
5976 * src/z80/gen.c: New support for bitfields
5977 * support/regression/tests/bitfields.c: reenabled z80,
5980 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5982 Rules 246.x, 247.x relate to bitfields, the others speed up
5983 access to xdata mapped I/O devices.
5985 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5987 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5989 Cleaned up genPackBits and genUnpackBits and added two helper
5990 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5991 for literal assignments in genPackBits (thanks to Frieder for
5997 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5999 Fixed bug #748310 (pointer to function type mishandled when the
6000 function name is omitted). Also fixed a SIGSEGV when a function
6001 attribute (reentrant, etc) is used on a non-function or on a
6002 function but misplaced before the parameter list.

6029 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6031 Made the constant following the "interrupt" keyword optional. If
6032 omitted, the function will not automatically be given an entry
6033 in the interrupt vector table (similar to #pragma NOIV, but
6034 less syntacticly kludgy). The interrupt number is also now
6035 range checked. Also fixed a bug in the high order bit example

6538 * src/pic16/pcode.c: Cleaned warnings
6539 * src/pic16/pcodeflow.c: Cleaned warnings
6540 * src/pic16/pcoderegs.c: Cleaned warnings

6553 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6555 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6556 it can be defined with CFLAGS when running configure
6557 * src/SDCCmain.c: fixed compiling + linking with object files
6559 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6561 * configure.in: configure for pic16 port,
6562 added --disable-pic16-port
6563 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6564 * src/SDCCmain.c: linkOptions is changed to set *,
6565 added if/endif conditional macros to remove options help
6566 messages from optionsTable when a port is not configured, added
6567 support for the PIc16 port in the ports table, when executing
6568 the compiler with no port specified on command line, a default
6569 port is selected with the new macro DEFAULT_PORT which is
6570 defined in port.h, in setDefaultOptions() linkOptions is removed
6571 from initialization assignment, since now it is a set,
6572 parseCmdLine uses setParseWithComma for linkOptions, in
6573 linkEdit() linkOptions are accessed with new function indexSet()
6574 which returns the i'th item of a set variable. See SDCCset.c, in
6575 linkEdit() when calling buildCmdLine(), added linkOptions as
6576 last argument. Now users can pass arguments to gplink via the
6577 -Wl option, main() uses pic16glue() to glue up pic16 programs

6589 * src/pic16/glue.c: commented out some error producing lines
6590 * src/pic16/main.c: __config directives are commented out to stop
6591 gpasm complaining and test the linkage with gplink, _linkCmd and
6592 _asmCmd changed to be more gplink and gpasm friendly
6593 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6594 produced an error when parsed, peep rule 12 is added to utilize
6595 movff, but it is commented out since the pCode does not support
6596 yet a command with 2 address arguments
6598 2003-05-18 <johan AT balder>
6600 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6627 2003-05-11 Borut Razem <borut.razem AT siol.net>
6629 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6630 the path of bin directory, so that PATH is the only env. variable, which has to be set

7618 2003-01-07 <johan AT balder>
7620 * src/SDCCast.c (decorateType): fixed bug #600035

7635 * src/SDCCicode.c: fixed array add
7637 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7638 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7639 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7641 2003-01-04 <johan AT balder>
7643 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7645 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7646 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7658 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7659 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7661 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7663 * in \sdcc\as\mcs51\ changed these files in order to create an
7664 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7665 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7666 following files to include the previous two files: aslink.dsp,
7667 Makefile.aslink, Makefile.bcc, and Makefile.in.
7669 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7670 .adb instead of .cdb
7672 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7674 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7675 value from option --iram-size.
7677 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7679 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7682 2002-09-18 <wiml AT hhhh.org>
7684 * SDCClrange.h: exposed setFromRange() and setToRange()
7685 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7686 packRegsForAccUse() (bug 542397)
7687 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7688 multiple times and emitting the fetch operations more than once
7689 added aopGetUsesAcc() function to allow binary operators to
7690 fetch their operands in the correct order; made genMinus() emit
7691 compact code for X = LITERAL - Y
7693 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7694 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7695 sprintf() in line 1267.
7697 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7698 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7701 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7702 Changes to aslink (All the changes are marked with 'JCF'):
7704 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7707 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7708 area BSEG. Also moves, if possible, the DATA area down into the internal
7709 ram so more space is available.
7711 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7714 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7715 not bytes. Function summary() which creates a memory usage summary
7716 file with extension .mem. Reports of overlaping stack and small stack
7717 size. If the space for the stack is less than 16 bytes aslink trows a
7720 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7721 the 8051. Option 'y' for memory summary output file.
7723 Changes to sdcc (All the changes are marked with 'JCF'):
7725 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7727 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7728 overlaying area for it (uses RegBankUsed[4]).
7730 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7731 bank zero as used by default. By default aslink locates the stack
7732 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7733 the creation of the .mem file. Delegates the allocation of data area
7734 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7735 the begining of the stack area to aslink.
7737 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7738 glue() in SDCCglue.c creates an area for it.
7740 2002-09-03 Borut Razem <borut.razem AT siol.net>
7741 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7742 sdcc/src/pic/glue.c:
7743 introduced atexit() handler for teporay files removal in case of
7744 errors, assertions, ...
7746 2002-08-29 Borut Razem <borut.razem AT siol.net>
7747 * sdcc/support/cpp2/auto-host_vc_in.h:
7748 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7749 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7750 Maybe there is a similar problem with BORLANDC? It should be checked!
7752 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7753 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7754 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7755 was not executed, and the compiler (cl) launched a warning:
7756 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7758 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7759 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7761 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7762 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7764 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7765 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7766 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7767 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7768 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7769 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7770 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7771 - added Release configuration in VS projects
7772 - review of compiler an linker options
7773 - VC .exe files are generated in bin_vc directory, not to interfere
7774 with binaries generated from other projects (cygwin, mingw, bcc ...)
7776 * sdcc/src/yacc.dsp: added
7778 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7779 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7780 and insert the version number definitions from .version
7782 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7784 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7785 added - genarate auto-host.h using auto-host_vc_in.h as template
7788 removed from CVS, generated automatically
7790 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7791 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7793 2002-08-11 Borut Razem <borut.razem AT siol.net>
7794 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7796 2002-08-10 Borut Razem <borut.razem AT siol.net>
7797 * src/SDCCmain.c (main):
7798 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7799 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7800 The consequence was that some temporary files were not removed.
7803 unification of code in functions tempfilename() and tempfile():
7804 function tempnam() is defined in Visual Studio 6.0 and .NET
7806 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7808 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7809 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7810 - removed compiler command line option /WX: Treats all warnings as errors
7811 - update a list of source files, included into the project
7813 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7814 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7815 changed project type to Generic Project so that can be correcly converted to VS.NET project
7817 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7819 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7821 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7823 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7824 added return 0 statements after assert() to make compiler happy
7826 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7827 added newline in the def file to keep MSC compiler satisfied
7829 * sdcc/src/z80/gen.c:
7830 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7831 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
