2314 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2316 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2317 loaded with the linker search paths (-L arguments) and the libraries
2318 to be linked with the current source (-l arguments). Changes
2319 currently will affect only the pic16 port.
2320 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2321 include path the port specific paths and port specific libraries,
2322 * gplink command now contains the $3 argument,
2323 * src/pic16/device.h,
2324 * src/pic16/device.c,: structure PIC_device is made public and
2325 renamed to PIC16_device, the same for variable Pics which is renamed
2326 to Pics16. Updated all references to them.
2327 * src/pic16/glue.c (pic16glue): corrected bug with code
2328 initialization which bypassed the variable initializations block.

2338 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2340 Documenting changes from previous commits.
2341 * configure.in (version 1.56),
2342 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2343 when generating output files to configure the pic16 library,
2344 but now I've commented it out, since gputils aren't installed in the
2345 SF compile farm, so library won't compile
2347 * device/lib/Makefile.in (version 1.56): initially I've added in
2348 target 'all' the prerequestive 'model-pic16' so it compiled the
2349 pic16 library, but now I've commented it out for the same reasons
2351 * added targets 'model-pic16' and 'objects-pic16' to compile the
2353 * added target 'port-specific-objects-pic16' to handle the
2354 generated libraries and copy them into the build/ directory
2355 * added target 'clean-intermediate-pic16' to clean intermediate
2356 files into pic16 directory
2357 * in target 'installdirs' added line to create directory pic16 in
2358 the installation path
2360 * device/include/Makefile.in (version 1.11): in target 'install'
2361 added lines to copy all header files to installation path,
2362 * in target 'installdirs' added line create directory for pic16
2363 headers in the installation path

2378 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2379 option so that it actually works. Made it specific to the z80, since
2380 the gbz80 doesn't have these kinds of I/O ports.
2382 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2384 * device/include/z180.h,

2397 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2399 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2400 changed interrupt vector table generation to only emit declared vectors.
2401 * device/include/Makefile.in: added missing backslash
2402 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

2406 Mainly changes to support compilation of the device libraries
2407 * src/pic16/device.c: stack is allocated via symbol and not
2408 via literal number. The symbol is placed in the corresponding
2409 position of the data ram
2410 * (pic16_dump_section): relocatable and absolute uninitialized
2411 data are now emitted in sorted order to reduce section naming,
2412 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2413 weren't marked as being in the access bank,
2415 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2417 Added portion of GNU PIC Library under the directory
2418 device/include/pic16 and device/lib/pic16. These files
2419 contain the declarations of SFRs for the PIC18Fxx2 devices.
2420 The directory is initialized via configure from toplevel.
2422 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2424 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2425 the spilllocations to be compared correctly
2427 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2429 * src/SDCCast.c (decorateType): fixed bug introduced today
2431 2004-01-12 Borut Razem <borut.razem AT siol.net>
2433 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2436 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2438 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
2439 in simpler and even better code
2441 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
2443 * src/SDCCicode.c (operandOperation): fixed bug #874819

2449 * doc/sdccman.lyx: Moved and added some sections, small changes
2450 all over. Telling LaTeX to be less strict with word spacing
2451 to better keep the right margin. Changed some notes about
2452 maintainance of the ports in section 3.2.1 - is it OK like this?
2454 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2491 UPPER for immediate operands,
2492 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2494 * src/pic16/peeph.def: all peepholes with movff are commented out,
2495 because there is a problem in the pcode peep optimizer,
2496 * src/pic16/ralloc.c: the register allocator can now reuse local

2498 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2500 Added file src/pic16/NOTES with information about program writing on
2501 the current port version.

2510 * src/SDCCmain.c : fixed #872250: -l command line defined library
2511 files are scanned before standard library files
2513 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2530 gen51Code): more efficient parameter receive for --model-large
2533 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2536 * src/z80/main.c: added missed needLinkerScript flags (more than
2537 one port structure defined in these file)
2538 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2554 needLinkerScript flag
2556 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2557 * src/pic/glue.c: added variable udata_section_name to
2558 override default uninitialized data segment definition for

2561 directive when no overlay data exist
2562 * (picglue): modified to emit uninitialized data segment
2563 according to udata_section_name

2573 2004-01-07 Borut Razem <borut.razem AT siol.net>
2575 * support/scripts/sdcc.nsi: update PATH
2576 * support/scripts/sdcc.ico: craeted
2578 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

2581 * doc/Makefile: fix install
2583 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2585 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
2587 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

2589 include information about variables allocated to the overlay
2592 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2594 * as/mcs51/lkmain.c: Help about -Y option

2606 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2608 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2609 (default behaviour).
2611 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2613 A python script to validate compiler diagnostic messages. It can be
2614 used to verify that sdcc complains about bad c source code and
2615 gives a good location of the error.
2616 * support/valdiag/Makefile,
2617 * support/valdiag/valdiag.py,
2618 * support/valdiag/tests/*
2620 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2622 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
2623 * src/SDCCsymt.c (newEnumType),

2631 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2633 * src/common.h: added ifndef/define/endif macros
2634 around the header file.
2635 Bug reported from Jesus Calvino-Fraga
2637 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2639 * sdcc.spec: updated
2640 * device/include/Makefile.in: don't install CVS directories
2641 * device/lib/Makefile.in: added removal of CVS directories after install
2642 * doc/Makefile: fixed install, added local_icons
2643 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2644 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2645 * src/ds390/gen.c (genRightShift): fixed bug #870788
2646 * src/SDCCast.c (decorateType): fixed bug #870781
2648 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2650 PIC16 port related changes:
2651 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2652 added variable stackPos,
2654 * gen.c: genCall, assignResultValue: added support for
2655 pushing/retrieving function parameters to/from stack,
2656 genFunction,genEndFunction: setup stack frame for the
2658 genAddrOf: will be changed according to bug 863624
2660 * added files genutils.c and genutils.h which contain gen*
2661 debugged and optimised functions extracted from gen.c
2663 * glue.c: added variable 'externs' which holds extern symbols,
2664 pic16emitRegularMap: is modified to properly handle relocatable
2665 symbols under the new scheme,
2666 pic16createInterruptVect: is modified
2667 pic16printPublics: is modified to emit 'global' assembler directives,
2668 added pic16_printExterns to print extern symbols,
2669 pic16glue: initializes stack/frame pointer in the beginning of
2670 the assembly output. Temporary hack, will be corrected later,
2671 because gplink yet does not support stack and SDCC does not
2672 yet support a type of crt0.o object to create the final binary.
2674 * Removed many lines that contain 8051 legacy code.
2675 * The code is finally placed under a 'code' directive.
2676 * Added port specific options.
2678 * _process_pragma: simplified since now we do not need *special*
2679 include file to define SFR registers. But a separate header
2680 will be needed. This will be developed later.
2681 * _pic16_parseOptions: added, parses port specific options:
2682 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2683 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2684 --preplace-udata-with=
2686 * _pic16_setDefaultOptions: modified to initialize section names,
2687 but hack is temporarly out of order since it needs improvement.
2688 * _pic16_genAssemblerPreamble: configuration words are emitted by
2689 their address instead of their name. This part is incomplete and
2690 supports only the 18Fxx2 devices. Other devices will emit an error
2691 during assembly since they do not contain the same set of config
2693 * _pic16_genIVT: is modified,
2695 * pcode.c: added definitions for some hardware registers that are needed
2697 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2698 All PCI entries are updated. Now LFSR is supported.
2699 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2700 * added pic16_newpCodeOpLit2 to support instructions with
2701 two literal arguments
2702 * pic16_pCode2str: corrected code that emits assembler instructions
2703 with two literal operands and those that have an access bit modifier
2704 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2705 this fixes a bug which caused some labels to be lost, when an
2706 assembler directive was added, i.e. banksel,
2707 * pic16_FixRegisterBanking: improved logic that causes the insertion
2709 * InlineFunction: functions that are called once, are not any more
2710 inlined. This can be a port option in the future,
2712 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2714 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2715 hold the corresponding uninitialized symbols,
2716 * pic16_allocProcessorRegister: registers have explicit marked the
2718 * pic16_allocInternalRegister: registers are explicit marked as
2720 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2721 processing list, so bit registers were lost,
2724 * ralloc.h: added field 'accessBank' and original symbol operand
2725 in register definition,
2726 * removed the field isMapped from register definition,
2728 ** Several functions have been removed from various sources:
2729 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2730 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2731 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2732 pic16_assignRelocatableRegisters
2734 ** others have been introduced:
2735 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2736 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2738 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2740 * support/scripts/inc2h.pl: changed definition of BIT_AT
2741 to emit 'sbit at' instead of 'bit at'. This was a request.
2743 PIC16 port related preliminary changes:
2744 * gen.c: prefixed function popRegFromString with
2745 pic16_ and all references to it corrected
2746 * pcode.c: all pic16_pc_* hardware registers prefixed
2747 with underscore (_),
2748 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2749 * ralloc.c: newReg(): when register is REG_SFR then
2750 set address to rIdx,
2751 pic16_allocProcessorRegister(): marks register wasUsed=0
2752 pic16_writeUsedRegs(): added a call to assign processor
2753 registers via pic16_assignFixedRegisters
2755 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2757 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2758 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2759 variables in unused register banks. Also the SSEG is placed
2760 wherever there is enough space for it, and IDATA can be anywhere
2761 in internal RAM. For now compile using -Wl-Y[stack_size].
2762 The mem file is different for this option as well, since it
2763 makes no sense of talking about DSEG lenght.
2765 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2767 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2768 in certain cases, e.g. when ROM assignment, patch provided
2769 from Albert den Haan.
2771 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2782 (geniCodeArray): ditto
2783 * src/SDCCicode.h: made geniCodeCast() static: removed prototype
2784 * src/SDCCsymt.c (computeType): added more support for char;

3778 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3779 If they pop r0/r1 they must be called in the opposite order than aopOp().
3780 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3781 (resp. --stack-auto), prepared for --xstack

3792 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3794 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3795 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3796 type for bits was changed. It resulted in bit variables becoming
3797 global, which is not permitted in PIC 14 assembly output.
3799 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3801 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3814 A few small changes that speed up the peephole optimizer.
3818 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3820 Try to make the peephole optimizer smarter by maintaining
3821 an association between the assembly source code and the
3822 iCodes that originated them. Put this information to use
3823 with a new peephole rule condition "notVolatile" so that
3824 the rules can be aggressive yet still safe.
3829 * src/mcs51/peeph.def
3831 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3835 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3836 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3837 if the left or right operand symbols have the accuse flag set.
3839 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3841 Changed the type of the result of the ! (NOT) operator to char;
3842 previously it returned the same type as the source. This allows
3843 us to eliminate all the genFloatNot functions (all of its target
3844 implementations were very buggy) since !float can use the same
3847 * src/SDCCicode.c (ast2iCode): ! returns char

3856 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3857 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3858 during interrupts. Ensure WSAVE is located at a shared bank address.
3859 2. Fixed page selection in some places
3860 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3861 the registers name strings.
3862 4. Fixed "signed / unsigned compare" compiler warnings.
3863 5. The PIC port manages its own allocation of the general purpose
3864 registers, but makes no attempt to reuse them. As a result when
3865 compiling it soon runs out of general purpose registers. Some
3866 additional code was added to the files pcode.c and device.c to walk
3867 through the function call tree and rename the registers so that they
3877 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3878 genPlus() & genMinus() when the result is the same as left or right

3884 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3886 Made bitfield a distinct type from bit so that bitfields
3887 convert as per ANSI C and bits retain their traditional
3888 boolean style behaviour. Implemented bitfield support in
3896 * src/ds390/gen.c: bit v bitfield split
3897 * src/z80/gen.c: New support for bitfields
3898 * support/regression/tests/bitfields.c: reenabled z80,
3901 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3903 Rules 246.x, 247.x relate to bitfields, the others speed up
3904 access to xdata mapped I/O devices.
3906 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3908 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3910 Cleaned up genPackBits and genUnpackBits and added two helper
3911 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3912 for literal assignments in genPackBits (thanks to Frieder for
3918 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3920 Fixed bug #748310 (pointer to function type mishandled when the
3921 function name is omitted). Also fixed a SIGSEGV when a function
3922 attribute (reentrant, etc) is used on a non-function or on a
3923 function but misplaced before the parameter list.
3925 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3927 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3950 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3952 Made the constant following the "interrupt" keyword optional. If
3953 omitted, the function will not automatically be given an entry
3954 in the interrupt vector table (similar to #pragma NOIV, but
3955 less syntacticly kludgy). The interrupt number is also now
3956 range checked. Also fixed a bug in the high order bit example

3970 * src/SDCCicode.c (operandOperation): rewritten some ops
3971 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3972 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3974 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3975 be re-activated by defining REDUCE_LITERALS)
3976 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3977 unsigned, but are signed by default
3978 * src/SDCCval.c (constVal): rearranged
3979 * src/SDCCval.c (valMod): preliminary fix
3980 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4432 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4433 the regression tests I'm not brave enough to enable 245.b, 245.c
4434 * doc/sdccman.lyx: added latex preamble for hyperref package.
4435 Using pdflatex this will give you a hyperlinked pdf file with
4436 bookmarks. (prepend '%' before /usepackage if this breaks something)

4452 Applied patch from bug 737905 (renamed yylineo to mylineno):
4459 * src/pic16/pcode.c: Cleaned warnings
4460 * src/pic16/pcodeflow.c: Cleaned warnings
4461 * src/pic16/pcoderegs.c: Cleaned warnings

4474 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4476 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4477 it can be defined with CFLAGS when running configure
4478 * src/SDCCmain.c: fixed compiling + linking with object files
4480 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4482 * configure.in: configure for pic16 port,
4483 added --disable-pic16-port
4484 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4485 * src/SDCCmain.c: linkOptions is changed to set *,
4486 added if/endif conditional macros to remove options help
4487 messages from optionsTable when a port is not configured, added
4488 support for the PIc16 port in the ports table, when executing
4489 the compiler with no port specified on command line, a default
4490 port is selected with the new macro DEFAULT_PORT which is
4491 defined in port.h, in setDefaultOptions() linkOptions is removed
4492 from initialization assignment, since now it is a set,
4493 parseCmdLine uses setParseWithComma for linkOptions, in
4494 linkEdit() linkOptions are accessed with new function indexSet()
4495 which returns the i'th item of a set variable. See SDCCset.c, in
4496 linkEdit() when calling buildCmdLine(), added linkOptions as
4497 last argument. Now users can pass arguments to gplink via the
4498 -Wl option, main() uses pic16glue() to glue up pic16 programs
4499 * src/SDCCpeeph.c: various changes to support pic16

4510 * src/pic16/glue.c: commented out some error producing lines
4511 * src/pic16/main.c: __config directives are commented out to stop
4512 gpasm complaining and test the linkage with gplink, _linkCmd and
4513 _asmCmd changed to be more gplink and gpasm friendly
4514 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4515 produced an error when parsed, peep rule 12 is added to utilize
4516 movff, but it is commented out since the pCode does not support
4517 yet a command with 2 address arguments
4519 2003-05-18 <johan AT balder>
4521 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4522 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4546 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4548 2003-05-11 Borut Razem <borut.razem AT siol.net>
4550 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4551 the path of bin directory, so that PATH is the only env. variable, which has to be set
4552 in case of standard installation.
4553 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5582 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5584 * in \sdcc\as\mcs51\ changed these files in order to create an
5585 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5586 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5587 following files to include the previous two files: aslink.dsp,
5588 Makefile.aslink, Makefile.bcc, and Makefile.in.
5590 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5591 .adb instead of .cdb
5593 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5595 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5596 value from option --iram-size.
5598 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5600 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5603 2002-09-18 <wiml AT hhhh.org>
5605 * SDCClrange.h: exposed setFromRange() and setToRange()
5606 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5607 packRegsForAccUse() (bug 542397)
5608 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5609 multiple times and emitting the fetch operations more than once
5610 added aopGetUsesAcc() function to allow binary operators to
5611 fetch their operands in the correct order; made genMinus() emit
5612 compact code for X = LITERAL - Y
5614 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5615 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5616 sprintf() in line 1267.
5618 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5619 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5622 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5623 Changes to aslink (All the changes are marked with 'JCF'):
5625 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5628 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5629 area BSEG. Also moves, if possible, the DATA area down into the internal
5630 ram so more space is available.
5632 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5635 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5636 not bytes. Function summary() which creates a memory usage summary
5637 file with extension .mem. Reports of overlaping stack and small stack
5638 size. If the space for the stack is less than 16 bytes aslink trows a
5641 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5642 the 8051. Option 'y' for memory summary output file.
5644 Changes to sdcc (All the changes are marked with 'JCF'):
5646 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5648 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5649 overlaying area for it (uses RegBankUsed[4]).
5651 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5652 bank zero as used by default. By default aslink locates the stack
5653 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5654 the creation of the .mem file. Delegates the allocation of data area
5655 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5656 the begining of the stack area to aslink.
5658 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5659 glue() in SDCCglue.c creates an area for it.
5661 2002-09-03 Borut Razem <borut.razem AT siol.net>
5662 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5663 sdcc/src/pic/glue.c:
5664 introduced atexit() handler for teporay files removal in case of
5665 errors, assertions, ...
5667 2002-08-29 Borut Razem <borut.razem AT siol.net>
5668 * sdcc/support/cpp2/auto-host_vc_in.h:
5669 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5670 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5671 Maybe there is a similar problem with BORLANDC? It should be checked!
5673 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5674 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5675 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5676 was not executed, and the compiler (cl) launched a warning:
5677 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5679 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5680 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

5691 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5692 - added Release configuration in VS projects
5693 - review of compiler an linker options
5694 - VC .exe files are generated in bin_vc directory, not to interfere
5695 with binaries generated from other projects (cygwin, mingw, bcc ...)
5697 * sdcc/src/yacc.dsp: added
5699 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5700 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5701 and insert the version number definitions from .version
5703 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5705 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

5711 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5712 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5714 2002-08-11 Borut Razem <borut.razem AT siol.net>
5715 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5717 2002-08-10 Borut Razem <borut.razem AT siol.net>
5718 * src/SDCCmain.c (main):
5719 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5720 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5721 The consequence was that some temporary files were not removed.
5724 unification of code in functions tempfilename() and tempfile():
5725 function tempnam() is defined in Visual Studio 6.0 and .NET
5727 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5729 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5730 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5731 - removed compiler command line option /WX: Treats all warnings as errors
5732 - update a list of source files, included into the project
5734 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5735 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5736 changed project type to Generic Project so that can be correcly converted to VS.NET project
5738 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5740 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

5744 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5745 added return 0 statements after assert() to make compiler happy
5747 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5748 added newline in the def file to keep MSC compiler satisfied
5750 * sdcc/src/z80/gen.c:
5751 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5752 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5753 - solved MSC error in function aopDump()
5755 * sdcc_vc.h: define PREFIX as "\\sdcc"
5757 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

5813 were not getting allocated.
5815 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5818 Fixed left shift. Will promote the left side of a left shift
5819 if a) left shifting more than size of operand or b) when assigned
5820 to something size > size of left side
5822 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5932 * sdcc/src/SDCCloop.c:
5933 Previous fix was not good. basic blocks that have "break" or "return" are
5934 not really partof a loop , but live ranges used in these blocks should
5935 be live thru the entire loop, so set partOfLoop but don't add them to
5938 2002-02-21 <johan AT FRIJA>

6811 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
6813 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
6815 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
