2292 loaded with the linker search paths (-L arguments) and the libraries
2293 to be linked with the current source (-l arguments). Changes
2294 currently will affect only the pic16 port.
2295 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2296 include path the port specific paths and port specific libraries,
2297 * gplink command now contains the $3 argument,

2302 * src/pic16/glue.c (pic16glue): corrected bug with code
2303 initialization which bypassed the variable initializations block.
2305 * device/lib/pic16/Makefile.rules: removed --penable-stack from
2306 COMPILE_FLAGS and added the --nostdinc option
2308 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2310 * device/include/mc68hc908jb8.h: Register defs for another member

2313 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2315 Documenting changes from previous commits.
2316 * configure.in (version 1.56),
2317 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2318 when generating output files to configure the pic16 library,
2319 but now I've commented it out, since gputils aren't installed in the
2320 SF compile farm, so library won't compile
2322 * device/lib/Makefile.in (version 1.56): initially I've added in
2323 target 'all' the prerequestive 'model-pic16' so it compiled the
2324 pic16 library, but now I've commented it out for the same reasons
2326 * added targets 'model-pic16' and 'objects-pic16' to compile the
2328 * added target 'port-specific-objects-pic16' to handle the
2329 generated libraries and copy them into the build/ directory
2330 * added target 'clean-intermediate-pic16' to clean intermediate
2331 files into pic16 directory
2332 * in target 'installdirs' added line to create directory pic16 in
2333 the installation path
2335 * device/include/Makefile.in (version 1.11): in target 'install'
2336 added lines to copy all header files to installation path,
2337 * in target 'installdirs' added line create directory for pic16
2338 headers in the installation path
2340 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

2353 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2354 option so that it actually works. Made it specific to the z80, since
2355 the gbz80 doesn't have these kinds of I/O ports.
2357 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2359 * device/include/z180.h,

2372 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2374 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2375 changed interrupt vector table generation to only emit declared vectors.

2381 Mainly changes to support compilation of the device libraries
2382 * src/pic16/device.c: stack is allocated via symbol and not
2383 via literal number. The symbol is placed in the corresponding
2384 position of the data ram
2385 * (pic16_dump_section): relocatable and absolute uninitialized
2386 data are now emitted in sorted order to reduce section naming,
2387 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2388 weren't marked as being in the access bank,
2390 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2392 Added portion of GNU PIC Library under the directory
2393 device/include/pic16 and device/lib/pic16. These files
2394 contain the declarations of SFRs for the PIC18Fxx2 devices.
2395 The directory is initialized via configure from toplevel.
2397 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2399 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2400 the spilllocations to be compared correctly
2402 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2404 * src/SDCCast.c (decorateType): fixed bug introduced today
2406 2004-01-12 Borut Razem <borut.razem AT siol.net>

2424 * doc/sdccman.lyx: Moved and added some sections, small changes
2425 all over. Telling LaTeX to be less strict with word spacing
2426 to better keep the right margin. Changed some notes about
2427 maintainance of the ports in section 3.2.1 - is it OK like this?
2429 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2466 UPPER for immediate operands,
2467 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2469 * src/pic16/peeph.def: all peepholes with movff are commented out,
2470 because there is a problem in the pcode peep optimizer,
2471 * src/pic16/ralloc.c: the register allocator can now reuse local
2472 function symbols for another function. This saves register usage.
2473 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2475 Added file src/pic16/NOTES with information about program writing on
2476 the current port version.

2505 gen51Code): more efficient parameter receive for --model-large
2508 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2511 * src/z80/main.c: added missed needLinkerScript flags (more than
2512 one port structure defined in these file)
2513 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2529 needLinkerScript flag
2531 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2532 * src/pic/glue.c: added variable udata_section_name to
2533 override default uninitialized data segment definition for
2534 devices only with SHAREBANK memory (reported from Erik Epetrich)
2535 * (pic14emitOverlay): modified to emit a commented overlay segment
2536 directive when no overlay data exist
2537 * (picglue): modified to emit uninitialized data segment
2538 according to udata_section_name

2548 2004-01-07 Borut Razem <borut.razem AT siol.net>
2550 * support/scripts/sdcc.nsi: update PATH
2551 * support/scripts/sdcc.ico: craeted
2553 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

2564 include information about variables allocated to the overlay
2567 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2569 * as/mcs51/lkmain.c: Help about -Y option

2581 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2583 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2584 (default behaviour).
2586 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2588 A python script to validate compiler diagnostic messages. It can be
2589 used to verify that sdcc complains about bad c source code and
2590 gives a good location of the error.
2591 * support/valdiag/Makefile,
2592 * support/valdiag/valdiag.py,
2593 * support/valdiag/tests/*
2595 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2608 * src/common.h: added ifndef/define/endif macros
2609 around the header file.
2610 Bug reported from Jesus Calvino-Fraga
2612 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2614 * sdcc.spec: updated
2615 * device/include/Makefile.in: don't install CVS directories
2616 * device/lib/Makefile.in: added removal of CVS directories after install
2617 * doc/Makefile: fixed install, added local_icons
2618 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2619 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2620 * src/ds390/gen.c (genRightShift): fixed bug #870788
2621 * src/SDCCast.c (decorateType): fixed bug #870781
2623 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2625 PIC16 port related changes:
2626 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2627 added variable stackPos,
2629 * gen.c: genCall, assignResultValue: added support for
2630 pushing/retrieving function parameters to/from stack,
2631 genFunction,genEndFunction: setup stack frame for the
2633 genAddrOf: will be changed according to bug 863624
2635 * added files genutils.c and genutils.h which contain gen*
2636 debugged and optimised functions extracted from gen.c
2638 * glue.c: added variable 'externs' which holds extern symbols,
2639 pic16emitRegularMap: is modified to properly handle relocatable
2640 symbols under the new scheme,
2641 pic16createInterruptVect: is modified
2642 pic16printPublics: is modified to emit 'global' assembler directives,
2643 added pic16_printExterns to print extern symbols,
2644 pic16glue: initializes stack/frame pointer in the beginning of
2645 the assembly output. Temporary hack, will be corrected later,
2646 because gplink yet does not support stack and SDCC does not
2647 yet support a type of crt0.o object to create the final binary.
2649 * Removed many lines that contain 8051 legacy code.
2650 * The code is finally placed under a 'code' directive.
2651 * Added port specific options.
2653 * _process_pragma: simplified since now we do not need *special*
2654 include file to define SFR registers. But a separate header
2655 will be needed. This will be developed later.
2656 * _pic16_parseOptions: added, parses port specific options:
2657 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2658 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2659 --preplace-udata-with=
2661 * _pic16_setDefaultOptions: modified to initialize section names,
2662 but hack is temporarly out of order since it needs improvement.
2663 * _pic16_genAssemblerPreamble: configuration words are emitted by
2664 their address instead of their name. This part is incomplete and
2665 supports only the 18Fxx2 devices. Other devices will emit an error
2666 during assembly since they do not contain the same set of config
2668 * _pic16_genIVT: is modified,
2670 * pcode.c: added definitions for some hardware registers that are needed
2672 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2673 All PCI entries are updated. Now LFSR is supported.
2674 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2675 * added pic16_newpCodeOpLit2 to support instructions with
2676 two literal arguments
2677 * pic16_pCode2str: corrected code that emits assembler instructions
2678 with two literal operands and those that have an access bit modifier
2679 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2680 this fixes a bug which caused some labels to be lost, when an
2681 assembler directive was added, i.e. banksel,
2682 * pic16_FixRegisterBanking: improved logic that causes the insertion
2684 * InlineFunction: functions that are called once, are not any more
2685 inlined. This can be a port option in the future,
2687 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2689 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2690 hold the corresponding uninitialized symbols,
2691 * pic16_allocProcessorRegister: registers have explicit marked the
2693 * pic16_allocInternalRegister: registers are explicit marked as
2695 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2696 processing list, so bit registers were lost,
2699 * ralloc.h: added field 'accessBank' and original symbol operand
2700 in register definition,
2701 * removed the field isMapped from register definition,
2703 ** Several functions have been removed from various sources:
2704 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2705 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2706 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2707 pic16_assignRelocatableRegisters
2709 ** others have been introduced:
2710 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2711 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2713 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2715 * support/scripts/inc2h.pl: changed definition of BIT_AT
2716 to emit 'sbit at' instead of 'bit at'. This was a request.
2718 PIC16 port related preliminary changes:
2719 * gen.c: prefixed function popRegFromString with
2720 pic16_ and all references to it corrected
2721 * pcode.c: all pic16_pc_* hardware registers prefixed
2722 with underscore (_),
2723 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2724 * ralloc.c: newReg(): when register is REG_SFR then
2725 set address to rIdx,
2726 pic16_allocProcessorRegister(): marks register wasUsed=0
2727 pic16_writeUsedRegs(): added a call to assign processor
2728 registers via pic16_assignFixedRegisters
2730 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2732 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2733 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2734 variables in unused register banks. Also the SSEG is placed
2735 wherever there is enough space for it, and IDATA can be anywhere
2736 in internal RAM. For now compile using -Wl-Y[stack_size].
2737 The mem file is different for this option as well, since it
2738 makes no sense of talking about DSEG lenght.
2740 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2742 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2743 in certain cases, e.g. when ROM assignment, patch provided
2744 from Albert den Haan.
2746 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3789 A few small changes that speed up the peephole optimizer.
3793 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3795 Try to make the peephole optimizer smarter by maintaining
3796 an association between the assembly source code and the
3797 iCodes that originated them. Put this information to use
3798 with a new peephole rule condition "notVolatile" so that
3799 the rules can be aggressive yet still safe.
3804 * src/mcs51/peeph.def
3806 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3810 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3811 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3812 if the left or right operand symbols have the accuse flag set.
3814 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3816 Changed the type of the result of the ! (NOT) operator to char;
3817 previously it returned the same type as the source. This allows
3818 us to eliminate all the genFloatNot functions (all of its target
3819 implementations were very buggy) since !float can use the same
3822 * src/SDCCicode.c (ast2iCode): ! returns char
3823 * src/mcs51/gen.c (genNot, genNotFloat),
3824 * src/ds390/gen.c (genNot, genNotFloat),
3825 * src/z80/gen.c (genNot, genNotFloat),
3826 * src/pic/gen.c (genNot, genNotFloat),
3827 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

3831 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3832 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3833 during interrupts. Ensure WSAVE is located at a shared bank address.
3834 2. Fixed page selection in some places
3835 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3836 the registers name strings.
3837 4. Fixed "signed / unsigned compare" compiler warnings.
3838 5. The PIC port manages its own allocation of the general purpose
3839 registers, but makes no attempt to reuse them. As a result when
3840 compiling it soon runs out of general purpose registers. Some
3841 additional code was added to the files pcode.c and device.c to walk
3842 through the function call tree and rename the registers so that they
3852 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3853 genPlus() & genMinus() when the result is the same as left or right

3859 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3861 Made bitfield a distinct type from bit so that bitfields
3862 convert as per ANSI C and bits retain their traditional
3863 boolean style behaviour. Implemented bitfield support in
3871 * src/ds390/gen.c: bit v bitfield split
3872 * src/z80/gen.c: New support for bitfields
3873 * support/regression/tests/bitfields.c: reenabled z80,
3876 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3878 Rules 246.x, 247.x relate to bitfields, the others speed up
3879 access to xdata mapped I/O devices.
3881 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3883 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3885 Cleaned up genPackBits and genUnpackBits and added two helper
3886 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3887 for literal assignments in genPackBits (thanks to Frieder for
3893 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3895 Fixed bug #748310 (pointer to function type mishandled when the
3896 function name is omitted). Also fixed a SIGSEGV when a function
3897 attribute (reentrant, etc) is used on a non-function or on a
3898 function but misplaced before the parameter list.
3900 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3902 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3903 * support/Util/SDCCerr.h,

3925 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3927 Made the constant following the "interrupt" keyword optional. If
3928 omitted, the function will not automatically be given an entry
3929 in the interrupt vector table (similar to #pragma NOIV, but
3930 less syntacticly kludgy). The interrupt number is also now
3931 range checked. Also fixed a bug in the high order bit example

3947 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3949 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3950 be re-activated by defining REDUCE_LITERALS)

3952 unsigned, but are signed by default
3953 * src/SDCCval.c (constVal): rearranged
3954 * src/SDCCval.c (valMod): preliminary fix
3955 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4397 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4399 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
4400 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
4401 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
4402 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
4405 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4407 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4408 the regression tests I'm not brave enough to enable 245.b, 245.c
4409 * doc/sdccman.lyx: added latex preamble for hyperref package.
4410 Using pdflatex this will give you a hyperlinked pdf file with
4411 bookmarks. (prepend '%' before /usepackage if this breaks something)
4413 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

4423 * src/SDCCglue.c (printIval): fixed bug #739934
4425 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
4427 Applied patch from bug 737905 (renamed yylineo to mylineno):
4434 * src/pic16/pcode.c: Cleaned warnings
4435 * src/pic16/pcodeflow.c: Cleaned warnings
4436 * src/pic16/pcoderegs.c: Cleaned warnings

4449 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4451 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4452 it can be defined with CFLAGS when running configure
4453 * src/SDCCmain.c: fixed compiling + linking with object files
4455 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4457 * configure.in: configure for pic16 port,
4458 added --disable-pic16-port
4459 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4460 * src/SDCCmain.c: linkOptions is changed to set *,
4461 added if/endif conditional macros to remove options help
4462 messages from optionsTable when a port is not configured, added
4463 support for the PIc16 port in the ports table, when executing
4464 the compiler with no port specified on command line, a default
4465 port is selected with the new macro DEFAULT_PORT which is
4466 defined in port.h, in setDefaultOptions() linkOptions is removed
4467 from initialization assignment, since now it is a set,
4468 parseCmdLine uses setParseWithComma for linkOptions, in
4469 linkEdit() linkOptions are accessed with new function indexSet()
4470 which returns the i'th item of a set variable. See SDCCset.c, in
4471 linkEdit() when calling buildCmdLine(), added linkOptions as
4472 last argument. Now users can pass arguments to gplink via the
4473 -Wl option, main() uses pic16glue() to glue up pic16 programs
4474 * src/SDCCpeeph.c: various changes to support pic16
4475 * src/SDCCset.c: added function void *indexSet(set *, int) to

4483 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4485 * src/pic16/glue.c: commented out some error producing lines
4486 * src/pic16/main.c: __config directives are commented out to stop
4487 gpasm complaining and test the linkage with gplink, _linkCmd and
4488 _asmCmd changed to be more gplink and gpasm friendly
4489 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4490 produced an error when parsed, peep rule 12 is added to utilize
4491 movff, but it is commented out since the pCode does not support
4492 yet a command with 2 address arguments
4494 2003-05-18 <johan AT balder>
4496 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4497 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4498 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

4521 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4523 2003-05-11 Borut Razem <borut.razem AT siol.net>
4525 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4526 the path of bin directory, so that PATH is the only env. variable, which has to be set
4527 in case of standard installation.
4528 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5531 * src/SDCCicode.c: fixed array add
5533 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>

5535 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5537 2003-01-04 <johan AT balder>
5539 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5541 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5542 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5544 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5545 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

5554 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5555 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5557 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5559 * in \sdcc\as\mcs51\ changed these files in order to create an
5560 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5561 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5562 following files to include the previous two files: aslink.dsp,
5563 Makefile.aslink, Makefile.bcc, and Makefile.in.
5565 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5566 .adb instead of .cdb
5568 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5570 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5571 value from option --iram-size.
5573 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5575 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5578 2002-09-18 <wiml AT hhhh.org>
5580 * SDCClrange.h: exposed setFromRange() and setToRange()
5581 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5582 packRegsForAccUse() (bug 542397)
5583 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5584 multiple times and emitting the fetch operations more than once
5585 added aopGetUsesAcc() function to allow binary operators to
5586 fetch their operands in the correct order; made genMinus() emit
5587 compact code for X = LITERAL - Y
5589 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5590 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5591 sprintf() in line 1267.
5593 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5594 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5597 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5598 Changes to aslink (All the changes are marked with 'JCF'):
5600 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5603 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5604 area BSEG. Also moves, if possible, the DATA area down into the internal
5605 ram so more space is available.
5607 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5610 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5611 not bytes. Function summary() which creates a memory usage summary
5612 file with extension .mem. Reports of overlaping stack and small stack
5613 size. If the space for the stack is less than 16 bytes aslink trows a
5616 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5617 the 8051. Option 'y' for memory summary output file.
5619 Changes to sdcc (All the changes are marked with 'JCF'):
5621 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5623 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5624 overlaying area for it (uses RegBankUsed[4]).
5626 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5627 bank zero as used by default. By default aslink locates the stack
5628 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5629 the creation of the .mem file. Delegates the allocation of data area
5630 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5631 the begining of the stack area to aslink.
5633 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5634 glue() in SDCCglue.c creates an area for it.
5636 2002-09-03 Borut Razem <borut.razem AT siol.net>
5637 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5638 sdcc/src/pic/glue.c:
5639 introduced atexit() handler for teporay files removal in case of
5640 errors, assertions, ...
5642 2002-08-29 Borut Razem <borut.razem AT siol.net>
5643 * sdcc/support/cpp2/auto-host_vc_in.h:
5644 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5645 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5646 Maybe there is a similar problem with BORLANDC? It should be checked!
5648 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5649 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5650 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5651 was not executed, and the compiler (cl) launched a warning:
5652 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5654 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5655 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5657 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5658 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5660 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5661 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5662 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5663 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5664 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5665 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5666 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5667 - added Release configuration in VS projects
5668 - review of compiler an linker options
5669 - VC .exe files are generated in bin_vc directory, not to interfere
5670 with binaries generated from other projects (cygwin, mingw, bcc ...)
5672 * sdcc/src/yacc.dsp: added
5674 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5675 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5676 and insert the version number definitions from .version
5678 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5680 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5681 added - genarate auto-host.h using auto-host_vc_in.h as template
5684 removed from CVS, generated automatically
5686 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5687 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5689 2002-08-11 Borut Razem <borut.razem AT siol.net>
5690 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5692 2002-08-10 Borut Razem <borut.razem AT siol.net>
5693 * src/SDCCmain.c (main):
5694 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5695 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5696 The consequence was that some temporary files were not removed.
5699 unification of code in functions tempfilename() and tempfile():
5700 function tempnam() is defined in Visual Studio 6.0 and .NET
5702 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5704 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5705 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5706 - removed compiler command line option /WX: Treats all warnings as errors
5707 - update a list of source files, included into the project
5709 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

5722 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5723 added newline in the def file to keep MSC compiler satisfied
5725 * sdcc/src/z80/gen.c:
5726 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5727 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5728 - solved MSC error in function aopDump()

5908 Previous fix was not good. basic blocks that have "break" or "return" are
5909 not really partof a loop , but live ranges used in these blocks should
