2320 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2322 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2323 loaded with the linker search paths (-L arguments) and the libraries
2324 to be linked with the current source (-l arguments). Changes
2325 currently will affect only the pic16 port.
2326 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2327 include path the port specific paths and port specific libraries,
2328 * gplink command now contains the $3 argument,
2329 * src/pic16/device.h,
2330 * src/pic16/device.c,: structure PIC_device is made public and
2331 renamed to PIC16_device, the same for variable Pics which is renamed
2332 to Pics16. Updated all references to them.
2333 * src/pic16/glue.c (pic16glue): corrected bug with code
2334 initialization which bypassed the variable initializations block.
2336 * device/lib/pic16/Makefile.rules: removed --penable-stack from

2344 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2346 Documenting changes from previous commits.
2347 * configure.in (version 1.56),
2348 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2349 when generating output files to configure the pic16 library,
2350 but now I've commented it out, since gputils aren't installed in the
2351 SF compile farm, so library won't compile
2353 * device/lib/Makefile.in (version 1.56): initially I've added in
2354 target 'all' the prerequestive 'model-pic16' so it compiled the
2355 pic16 library, but now I've commented it out for the same reasons
2357 * added targets 'model-pic16' and 'objects-pic16' to compile the
2359 * added target 'port-specific-objects-pic16' to handle the
2360 generated libraries and copy them into the build/ directory
2361 * added target 'clean-intermediate-pic16' to clean intermediate
2362 files into pic16 directory
2363 * in target 'installdirs' added line to create directory pic16 in
2364 the installation path
2366 * device/include/Makefile.in (version 1.11): in target 'install'
2367 added lines to copy all header files to installation path,
2368 * in target 'installdirs' added line create directory for pic16
2369 headers in the installation path
2371 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

2384 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2385 option so that it actually works. Made it specific to the z80, since
2386 the gbz80 doesn't have these kinds of I/O ports.
2388 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2390 * device/include/z180.h,

2403 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2405 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2406 changed interrupt vector table generation to only emit declared vectors.
2407 * device/include/Makefile.in: added missing backslash
2408 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
2410 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2412 Mainly changes to support compilation of the device libraries
2413 * src/pic16/device.c: stack is allocated via symbol and not
2414 via literal number. The symbol is placed in the corresponding
2415 position of the data ram
2416 * (pic16_dump_section): relocatable and absolute uninitialized
2417 data are now emitted in sorted order to reduce section naming,
2418 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2419 weren't marked as being in the access bank,
2421 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2423 Added portion of GNU PIC Library under the directory
2424 device/include/pic16 and device/lib/pic16. These files
2425 contain the declarations of SFRs for the PIC18Fxx2 devices.
2426 The directory is initialized via configure from toplevel.
2428 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2430 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2431 the spilllocations to be compared correctly
2433 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2435 * src/SDCCast.c (decorateType): fixed bug introduced today
2437 2004-01-12 Borut Razem <borut.razem AT siol.net>
2439 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2442 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2444 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
2445 in simpler and even better code
2447 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
2449 * src/SDCCicode.c (operandOperation): fixed bug #874819

2453 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2455 * doc/sdccman.lyx: Moved and added some sections, small changes
2456 all over. Telling LaTeX to be less strict with word spacing
2457 to better keep the right margin. Changed some notes about
2458 maintainance of the ports in section 3.2.1 - is it OK like this?
2460 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2462 SDCC source changes:
2463 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2496 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
2497 UPPER for immediate operands,
2498 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2500 * src/pic16/peeph.def: all peepholes with movff are commented out,
2501 because there is a problem in the pcode peep optimizer,
2502 * src/pic16/ralloc.c: the register allocator can now reuse local
2503 function symbols for another function. This saves register usage.
2504 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2506 Added file src/pic16/NOTES with information about program writing on
2507 the current port version.

2516 * src/SDCCmain.c : fixed #872250: -l command line defined library
2517 files are scanned before standard library files
2519 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2533 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2535 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
2536 gen51Code): more efficient parameter receive for --model-large
2539 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2542 * src/z80/main.c: added missed needLinkerScript flags (more than
2543 one port structure defined in these file)
2544 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2547 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

2550 * src/port.h: added flag needLinkerScript in port->linker
2551 structure to inform whether to create a .lnk file or not,
2559 * src/z80/main.c: changed appropriately to configure
2560 needLinkerScript flag
2562 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2563 * src/pic/glue.c: added variable udata_section_name to
2564 override default uninitialized data segment definition for
2565 devices only with SHAREBANK memory (reported from Erik Epetrich)
2566 * (pic14emitOverlay): modified to emit a commented overlay segment
2567 directive when no overlay data exist
2568 * (picglue): modified to emit uninitialized data segment
2569 according to udata_section_name

2574 arguments via -W option
2575 * src/pic16/main.c: added $l in _asmCmd, changed extension for
2576 object file from '.rel' to '.o' in port->linker structure,
2577 changed size of fptr from 2 to 3 in port structure
2579 2004-01-07 Borut Razem <borut.razem AT siol.net>
2581 * support/scripts/sdcc.nsi: update PATH
2582 * support/scripts/sdcc.ico: craeted
2584 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
2586 * device/include/Makefile.in: fix install
2587 * doc/Makefile: fix install
2589 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2591 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
2593 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
2594 how the function variable allocation summary is displayed; also
2595 include information about variables allocated to the overlay
2598 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2600 * as/mcs51/lkmain.c: Help about -Y option

2610 LEFT_OP (left shift)
2612 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2614 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2615 (default behaviour).
2617 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2619 A python script to validate compiler diagnostic messages. It can be
2620 used to verify that sdcc complains about bad c source code and
2621 gives a good location of the error.
2622 * support/valdiag/Makefile,
2623 * support/valdiag/valdiag.py,
2624 * support/valdiag/tests/*
2626 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2628 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
2629 * src/SDCCsymt.c (newEnumType),

2637 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2639 * src/common.h: added ifndef/define/endif macros
2640 around the header file.
2641 Bug reported from Jesus Calvino-Fraga
2643 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2645 * sdcc.spec: updated
2646 * device/include/Makefile.in: don't install CVS directories
2647 * device/lib/Makefile.in: added removal of CVS directories after install
2648 * doc/Makefile: fixed install, added local_icons
2649 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2650 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2651 * src/ds390/gen.c (genRightShift): fixed bug #870788
2652 * src/SDCCast.c (decorateType): fixed bug #870781
2654 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2656 PIC16 port related changes:
2657 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2658 added variable stackPos,
2660 * gen.c: genCall, assignResultValue: added support for
2661 pushing/retrieving function parameters to/from stack,
2662 genFunction,genEndFunction: setup stack frame for the
2664 genAddrOf: will be changed according to bug 863624
2666 * added files genutils.c and genutils.h which contain gen*
2667 debugged and optimised functions extracted from gen.c
2669 * glue.c: added variable 'externs' which holds extern symbols,
2670 pic16emitRegularMap: is modified to properly handle relocatable
2671 symbols under the new scheme,
2672 pic16createInterruptVect: is modified
2673 pic16printPublics: is modified to emit 'global' assembler directives,
2674 added pic16_printExterns to print extern symbols,
2675 pic16glue: initializes stack/frame pointer in the beginning of
2676 the assembly output. Temporary hack, will be corrected later,
2677 because gplink yet does not support stack and SDCC does not
2678 yet support a type of crt0.o object to create the final binary.
2680 * Removed many lines that contain 8051 legacy code.
2681 * The code is finally placed under a 'code' directive.
2682 * Added port specific options.
2684 * _process_pragma: simplified since now we do not need *special*
2685 include file to define SFR registers. But a separate header
2686 will be needed. This will be developed later.
2687 * _pic16_parseOptions: added, parses port specific options:
2688 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2689 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2690 --preplace-udata-with=
2692 * _pic16_setDefaultOptions: modified to initialize section names,
2693 but hack is temporarly out of order since it needs improvement.
2694 * _pic16_genAssemblerPreamble: configuration words are emitted by
2695 their address instead of their name. This part is incomplete and
2696 supports only the 18Fxx2 devices. Other devices will emit an error
2697 during assembly since they do not contain the same set of config
2699 * _pic16_genIVT: is modified,
2701 * pcode.c: added definitions for some hardware registers that are needed
2703 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2704 All PCI entries are updated. Now LFSR is supported.
2705 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2706 * added pic16_newpCodeOpLit2 to support instructions with
2707 two literal arguments
2708 * pic16_pCode2str: corrected code that emits assembler instructions
2709 with two literal operands and those that have an access bit modifier
2710 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2711 this fixes a bug which caused some labels to be lost, when an
2712 assembler directive was added, i.e. banksel,
2713 * pic16_FixRegisterBanking: improved logic that causes the insertion
2715 * InlineFunction: functions that are called once, are not any more
2716 inlined. This can be a port option in the future,
2718 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2720 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2721 hold the corresponding uninitialized symbols,
2722 * pic16_allocProcessorRegister: registers have explicit marked the
2724 * pic16_allocInternalRegister: registers are explicit marked as
2726 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2727 processing list, so bit registers were lost,
2730 * ralloc.h: added field 'accessBank' and original symbol operand
2731 in register definition,
2732 * removed the field isMapped from register definition,
2734 ** Several functions have been removed from various sources:
2735 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2736 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2737 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2738 pic16_assignRelocatableRegisters
2740 ** others have been introduced:
2741 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2742 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2744 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2746 * support/scripts/inc2h.pl: changed definition of BIT_AT
2747 to emit 'sbit at' instead of 'bit at'. This was a request.
2749 PIC16 port related preliminary changes:
2750 * gen.c: prefixed function popRegFromString with
2751 pic16_ and all references to it corrected
2752 * pcode.c: all pic16_pc_* hardware registers prefixed
2753 with underscore (_),
2754 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2755 * ralloc.c: newReg(): when register is REG_SFR then
2756 set address to rIdx,
2757 pic16_allocProcessorRegister(): marks register wasUsed=0
2758 pic16_writeUsedRegs(): added a call to assign processor
2759 registers via pic16_assignFixedRegisters
2761 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2763 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2764 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2765 variables in unused register banks. Also the SSEG is placed
2766 wherever there is enough space for it, and IDATA can be anywhere
2767 in internal RAM. For now compile using -Wl-Y[stack_size].
2768 The mem file is different for this option as well, since it
2769 makes no sense of talking about DSEG lenght.
2771 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2773 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2774 in certain cases, e.g. when ROM assignment, patch provided
2775 from Albert den Haan.
2777 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
2779 Many signedness and type propagation fixes:
2780 * src/SDCCicode.c: made geniCodeCast() static
2781 replaced SPEC_ by IS_ (cosmetic)
2782 (operandOperation): fixed div and mod operation
2783 (usualBinaryConversions): added support for promotion of char
2784 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
2785 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
2786 (geniCodeAdd): an array index will stay unsigned, even if promoted

3783 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3784 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3785 If they pop r0/r1 they must be called in the opposite order than aopOp().
3786 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3787 (resp. --stack-auto), prepared for --xstack

3796 these ports have their own __sdcc_external_start()
3798 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3800 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3801 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3802 type for bits was changed. It resulted in bit variables becoming
3803 global, which is not permitted in PIC 14 assembly output.
3805 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3807 * doc/sdccman.lyx: various additions and updates. Rearranged sections
3809 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3811 Z80 and MCS51 linkers complaint if a public symbol is defined

3820 A few small changes that speed up the peephole optimizer.
3824 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3826 Try to make the peephole optimizer smarter by maintaining
3827 an association between the assembly source code and the
3828 iCodes that originated them. Put this information to use
3829 with a new peephole rule condition "notVolatile" so that
3830 the rules can be aggressive yet still safe.
3835 * src/mcs51/peeph.def
3837 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3841 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3842 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3843 if the left or right operand symbols have the accuse flag set.
3845 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3847 Changed the type of the result of the ! (NOT) operator to char;
3848 previously it returned the same type as the source. This allows
3849 us to eliminate all the genFloatNot functions (all of its target
3850 implementations were very buggy) since !float can use the same
3853 * src/SDCCicode.c (ast2iCode): ! returns char

3855 * src/ds390/gen.c (genNot, genNotFloat),
3856 * src/z80/gen.c (genNot, genNotFloat),
3857 * src/pic/gen.c (genNot, genNotFloat),

3862 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3863 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3864 during interrupts. Ensure WSAVE is located at a shared bank address.
3865 2. Fixed page selection in some places
3866 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3867 the registers name strings.
3868 4. Fixed "signed / unsigned compare" compiler warnings.
3869 5. The PIC port manages its own allocation of the general purpose
3870 registers, but makes no attempt to reuse them. As a result when
3871 compiling it soon runs out of general purpose registers. Some
3872 additional code was added to the files pcode.c and device.c to walk
3873 through the function call tree and rename the registers so that they
3883 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3884 genPlus() & genMinus() when the result is the same as left or right

3890 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3892 Made bitfield a distinct type from bit so that bitfields
3893 convert as per ANSI C and bits retain their traditional
3894 boolean style behaviour. Implemented bitfield support in
3902 * src/ds390/gen.c: bit v bitfield split
3903 * src/z80/gen.c: New support for bitfields
3904 * support/regression/tests/bitfields.c: reenabled z80,
3907 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3909 Rules 246.x, 247.x relate to bitfields, the others speed up
3910 access to xdata mapped I/O devices.
3912 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3914 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3916 Cleaned up genPackBits and genUnpackBits and added two helper
3917 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3918 for literal assignments in genPackBits (thanks to Frieder for
3924 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3926 Fixed bug #748310 (pointer to function type mishandled when the
3927 function name is omitted). Also fixed a SIGSEGV when a function
3928 attribute (reentrant, etc) is used on a non-function or on a
3929 function but misplaced before the parameter list.
3931 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3933 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3956 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3958 Made the constant following the "interrupt" keyword optional. If
3959 omitted, the function will not automatically be given an entry
3960 in the interrupt vector table (similar to #pragma NOIV, but
3961 less syntacticly kludgy). The interrupt number is also now
3962 range checked. Also fixed a bug in the high order bit example

3978 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3980 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3981 be re-activated by defining REDUCE_LITERALS)
3982 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3983 unsigned, but are signed by default
3984 * src/SDCCval.c (constVal): rearranged
3985 * src/SDCCval.c (valMod): preliminary fix
3986 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4438 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4439 the regression tests I'm not brave enough to enable 245.b, 245.c
4440 * doc/sdccman.lyx: added latex preamble for hyperref package.
4441 Using pdflatex this will give you a hyperlinked pdf file with
4442 bookmarks. (prepend '%' before /usepackage if this breaks something)

4483 it can be defined with CFLAGS when running configure
4484 * src/SDCCmain.c: fixed compiling + linking with object files
4486 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4489 added --disable-pic16-port
4490 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4491 * src/SDCCmain.c: linkOptions is changed to set *,
4492 added if/endif conditional macros to remove options help
4493 messages from optionsTable when a port is not configured, added
4494 support for the PIc16 port in the ports table, when executing
4495 the compiler with no port specified on command line, a default
4496 port is selected with the new macro DEFAULT_PORT which is
4497 defined in port.h, in setDefaultOptions() linkOptions is removed
4498 from initialization assignment, since now it is a set,
4499 parseCmdLine uses setParseWithComma for linkOptions, in
4500 linkEdit() linkOptions are accessed with new function indexSet()
4501 which returns the i'th item of a set variable. See SDCCset.c, in
4502 linkEdit() when calling buildCmdLine(), added linkOptions as
4503 last argument. Now users can pass arguments to gplink via the
4504 -Wl option, main() uses pic16glue() to glue up pic16 programs
4505 * src/SDCCpeeph.c: various changes to support pic16

4516 * src/pic16/glue.c: commented out some error producing lines
4517 * src/pic16/main.c: __config directives are commented out to stop
4518 gpasm complaining and test the linkage with gplink, _linkCmd and
4519 _asmCmd changed to be more gplink and gpasm friendly
4520 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4521 produced an error when parsed, peep rule 12 is added to utilize
4522 movff, but it is commented out since the pCode does not support
4523 yet a command with 2 address arguments
4525 2003-05-18 <johan AT balder>
4527 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4528 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4552 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4554 2003-05-11 Borut Razem <borut.razem AT siol.net>
4556 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4557 the path of bin directory, so that PATH is the only env. variable, which has to be set
4558 in case of standard installation.
4559 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5588 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5590 * in \sdcc\as\mcs51\ changed these files in order to create an
5591 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5592 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5593 following files to include the previous two files: aslink.dsp,
5594 Makefile.aslink, Makefile.bcc, and Makefile.in.
5596 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5597 .adb instead of .cdb
5599 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5601 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5602 value from option --iram-size.
5604 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5606 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5609 2002-09-18 <wiml AT hhhh.org>
5611 * SDCClrange.h: exposed setFromRange() and setToRange()
5612 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5613 packRegsForAccUse() (bug 542397)
5614 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5615 multiple times and emitting the fetch operations more than once
5616 added aopGetUsesAcc() function to allow binary operators to
5617 fetch their operands in the correct order; made genMinus() emit
5618 compact code for X = LITERAL - Y
5620 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5621 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5622 sprintf() in line 1267.
5624 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5625 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5628 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5629 Changes to aslink (All the changes are marked with 'JCF'):
5631 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5634 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5635 area BSEG. Also moves, if possible, the DATA area down into the internal
5636 ram so more space is available.
5638 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5641 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5642 not bytes. Function summary() which creates a memory usage summary
5643 file with extension .mem. Reports of overlaping stack and small stack
5644 size. If the space for the stack is less than 16 bytes aslink trows a
5647 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5648 the 8051. Option 'y' for memory summary output file.
5650 Changes to sdcc (All the changes are marked with 'JCF'):
5652 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5654 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5655 overlaying area for it (uses RegBankUsed[4]).
5657 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5658 bank zero as used by default. By default aslink locates the stack
5659 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5660 the creation of the .mem file. Delegates the allocation of data area
5661 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5662 the begining of the stack area to aslink.
5664 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5665 glue() in SDCCglue.c creates an area for it.
5667 2002-09-03 Borut Razem <borut.razem AT siol.net>
5668 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5669 sdcc/src/pic/glue.c:
5670 introduced atexit() handler for teporay files removal in case of
5671 errors, assertions, ...
5673 2002-08-29 Borut Razem <borut.razem AT siol.net>
5674 * sdcc/support/cpp2/auto-host_vc_in.h:
5675 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5676 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5677 Maybe there is a similar problem with BORLANDC? It should be checked!
5679 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5680 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5681 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5682 was not executed, and the compiler (cl) launched a warning:
5683 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5685 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5686 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5688 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

5695 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5696 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5697 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5698 - added Release configuration in VS projects
5699 - review of compiler an linker options
5700 - VC .exe files are generated in bin_vc directory, not to interfere
5701 with binaries generated from other projects (cygwin, mingw, bcc ...)
5703 * sdcc/src/yacc.dsp: added
5705 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5706 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5707 and insert the version number definitions from .version
5709 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5711 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

5718 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5720 2002-08-11 Borut Razem <borut.razem AT siol.net>
5721 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5723 2002-08-10 Borut Razem <borut.razem AT siol.net>
5724 * src/SDCCmain.c (main):
5725 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5726 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5727 The consequence was that some temporary files were not removed.
5730 unification of code in functions tempfilename() and tempfile():
5731 function tempnam() is defined in Visual Studio 6.0 and .NET
5733 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5735 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5736 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5737 - removed compiler command line option /WX: Treats all warnings as errors
5738 - update a list of source files, included into the project
5740 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5741 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5742 changed project type to Generic Project so that can be correcly converted to VS.NET project
5744 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5746 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

5750 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5751 added return 0 statements after assert() to make compiler happy
5753 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5754 added newline in the def file to keep MSC compiler satisfied
5756 * sdcc/src/z80/gen.c:
5757 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5758 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5759 - solved MSC error in function aopDump()
5761 * sdcc_vc.h: define PREFIX as "\\sdcc"
5763 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

5819 were not getting allocated.
5821 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5824 Fixed left shift. Will promote the left side of a left shift
5825 if a) left shifting more than size of operand or b) when assigned
5826 to something size > size of left side
5828 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5938 * sdcc/src/SDCCloop.c:
5939 Previous fix was not good. basic blocks that have "break" or "return" are
5940 not really partof a loop , but live ranges used in these blocks should
5941 be live thru the entire loop, so set partOfLoop but don't add them to
5944 2002-02-21 <johan AT FRIJA>
