2303 safely allocate code/RAM of separate ASM files to different pages/banks.
2304 * doc/sdccman.lyx: added Slade's tips
2305 * src/mcs51/peeph.def: fixed bug #880768

2347 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2349 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2350 loaded with the linker search paths (-L arguments) and the libraries
2351 to be linked with the current source (-l arguments). Changes
2352 currently will affect only the pic16 port.
2353 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2354 include path the port specific paths and port specific libraries,
2355 * gplink command now contains the $3 argument,
2356 * src/pic16/device.h,
2357 * src/pic16/device.c,: structure PIC_device is made public and
2358 renamed to PIC16_device, the same for variable Pics which is renamed

2371 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2373 Documenting changes from previous commits.
2374 * configure.in (version 1.56),
2375 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2376 when generating output files to configure the pic16 library,
2377 but now I've commented it out, since gputils aren't installed in the
2378 SF compile farm, so library won't compile
2380 * device/lib/Makefile.in (version 1.56): initially I've added in
2381 target 'all' the prerequestive 'model-pic16' so it compiled the
2382 pic16 library, but now I've commented it out for the same reasons
2384 * added targets 'model-pic16' and 'objects-pic16' to compile the
2386 * added target 'port-specific-objects-pic16' to handle the
2387 generated libraries and copy them into the build/ directory
2388 * added target 'clean-intermediate-pic16' to clean intermediate
2389 files into pic16 directory
2390 * in target 'installdirs' added line to create directory pic16 in
2391 the installation path
2393 * device/include/Makefile.in (version 1.11): in target 'install'
2394 added lines to copy all header files to installation path,
2395 * in target 'installdirs' added line create directory for pic16
2396 headers in the installation path

2411 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2412 option so that it actually works. Made it specific to the z80, since
2413 the gbz80 doesn't have these kinds of I/O ports.
2415 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2417 * device/include/z180.h,

2430 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2432 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2433 changed interrupt vector table generation to only emit declared vectors.
2434 * device/include/Makefile.in: added missing backslash
2435 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

2439 Mainly changes to support compilation of the device libraries
2440 * src/pic16/device.c: stack is allocated via symbol and not
2441 via literal number. The symbol is placed in the corresponding
2442 position of the data ram
2443 * (pic16_dump_section): relocatable and absolute uninitialized
2444 data are now emitted in sorted order to reduce section naming,
2445 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2446 weren't marked as being in the access bank,
2448 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2450 Added portion of GNU PIC Library under the directory
2451 device/include/pic16 and device/lib/pic16. These files
2452 contain the declarations of SFRs for the PIC18Fxx2 devices.
2453 The directory is initialized via configure from toplevel.
2455 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2457 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2458 the spilllocations to be compared correctly
2460 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
2462 * src/SDCCast.c (decorateType): fixed bug introduced today
2464 2004-01-12 Borut Razem <borut.razem AT siol.net>
2466 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

2482 * doc/sdccman.lyx: Moved and added some sections, small changes
2483 all over. Telling LaTeX to be less strict with word spacing
2484 to better keep the right margin. Changed some notes about
2485 maintainance of the ports in section 3.2.1 - is it OK like this?
2487 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2525 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2527 * src/pic16/peeph.def: all peepholes with movff are commented out,
2528 because there is a problem in the pcode peep optimizer,
2529 * src/pic16/ralloc.c: the register allocator can now reuse local

2644 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2646 A python script to validate compiler diagnostic messages. It can be
2647 used to verify that sdcc complains about bad c source code and
2648 gives a good location of the error.
2649 * support/valdiag/Makefile,
2650 * support/valdiag/valdiag.py,
2651 * support/valdiag/tests/*
2653 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2668 Bug reported from Jesus Calvino-Fraga
2670 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2672 * sdcc.spec: updated
2673 * device/include/Makefile.in: don't install CVS directories

2677 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2678 * src/ds390/gen.c (genRightShift): fixed bug #870788
2679 * src/SDCCast.c (decorateType): fixed bug #870781
2681 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2683 PIC16 port related changes:
2684 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2685 added variable stackPos,
2687 * gen.c: genCall, assignResultValue: added support for
2688 pushing/retrieving function parameters to/from stack,
2689 genFunction,genEndFunction: setup stack frame for the
2691 genAddrOf: will be changed according to bug 863624
2693 * added files genutils.c and genutils.h which contain gen*
2694 debugged and optimised functions extracted from gen.c
2696 * glue.c: added variable 'externs' which holds extern symbols,
2697 pic16emitRegularMap: is modified to properly handle relocatable
2698 symbols under the new scheme,
2699 pic16createInterruptVect: is modified
2700 pic16printPublics: is modified to emit 'global' assembler directives,
2701 added pic16_printExterns to print extern symbols,
2702 pic16glue: initializes stack/frame pointer in the beginning of
2703 the assembly output. Temporary hack, will be corrected later,
2704 because gplink yet does not support stack and SDCC does not
2705 yet support a type of crt0.o object to create the final binary.
2707 * Removed many lines that contain 8051 legacy code.
2708 * The code is finally placed under a 'code' directive.
2709 * Added port specific options.
2711 * _process_pragma: simplified since now we do not need *special*
2712 include file to define SFR registers. But a separate header
2713 will be needed. This will be developed later.
2714 * _pic16_parseOptions: added, parses port specific options:
2715 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2716 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2717 --preplace-udata-with=
2719 * _pic16_setDefaultOptions: modified to initialize section names,
2720 but hack is temporarly out of order since it needs improvement.
2721 * _pic16_genAssemblerPreamble: configuration words are emitted by
2722 their address instead of their name. This part is incomplete and
2723 supports only the 18Fxx2 devices. Other devices will emit an error
2724 during assembly since they do not contain the same set of config
2726 * _pic16_genIVT: is modified,
2728 * pcode.c: added definitions for some hardware registers that are needed
2730 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2731 All PCI entries are updated. Now LFSR is supported.
2732 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2733 * added pic16_newpCodeOpLit2 to support instructions with
2734 two literal arguments
2735 * pic16_pCode2str: corrected code that emits assembler instructions
2736 with two literal operands and those that have an access bit modifier
2737 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2738 this fixes a bug which caused some labels to be lost, when an
2739 assembler directive was added, i.e. banksel,
2740 * pic16_FixRegisterBanking: improved logic that causes the insertion
2742 * InlineFunction: functions that are called once, are not any more
2743 inlined. This can be a port option in the future,
2745 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2747 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2748 hold the corresponding uninitialized symbols,
2749 * pic16_allocProcessorRegister: registers have explicit marked the
2751 * pic16_allocInternalRegister: registers are explicit marked as
2753 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2754 processing list, so bit registers were lost,
2757 * ralloc.h: added field 'accessBank' and original symbol operand
2758 in register definition,
2759 * removed the field isMapped from register definition,
2761 ** Several functions have been removed from various sources:
2762 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2763 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2764 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2765 pic16_assignRelocatableRegisters
2767 ** others have been introduced:
2768 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2769 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2771 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2773 * support/scripts/inc2h.pl: changed definition of BIT_AT
2774 to emit 'sbit at' instead of 'bit at'. This was a request.
2776 PIC16 port related preliminary changes:
2777 * gen.c: prefixed function popRegFromString with
2778 pic16_ and all references to it corrected
2779 * pcode.c: all pic16_pc_* hardware registers prefixed
2780 with underscore (_),
2781 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2782 * ralloc.c: newReg(): when register is REG_SFR then
2783 set address to rIdx,
2784 pic16_allocProcessorRegister(): marks register wasUsed=0
2785 pic16_writeUsedRegs(): added a call to assign processor
2786 registers via pic16_assignFixedRegisters
2788 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2790 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2791 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2792 variables in unused register banks. Also the SSEG is placed
2793 wherever there is enough space for it, and IDATA can be anywhere
2794 in internal RAM. For now compile using -Wl-Y[stack_size].
2795 The mem file is different for this option as well, since it
2796 makes no sense of talking about DSEG lenght.

3784 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
3786 * device/lib/_mullong.c: replaced int by short for gcc
3788 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3790 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
3791 and JUMPTABLE iCodes properly now (worked by accident before)
3792 * src/mcs51/gen.c (leftRightUseAcc),
3793 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3794 iCode properly now. Use getSize instead of nRegs since a & b
3795 aren't part of the nRegs tally.
3797 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3799 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
3800 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
3801 before instructions that use the _STATUS register
3803 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
3805 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3806 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3807 fetching of the pointer
3808 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3809 copied from genNearPointerSet()
3810 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3811 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3812 If they pop r0/r1 they must be called in the opposite order than aopOp().
3813 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3814 (resp. --stack-auto), prepared for --xstack

3820 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
3822 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
3823 these ports have their own __sdcc_external_start()
3825 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3827 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3828 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3829 type for bits was changed. It resulted in bit variables becoming
3830 global, which is not permitted in PIC 14 assembly output.
3832 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3834 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3847 A few small changes that speed up the peephole optimizer.
3851 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3853 Try to make the peephole optimizer smarter by maintaining
3854 an association between the assembly source code and the
3855 iCodes that originated them. Put this information to use
3856 with a new peephole rule condition "notVolatile" so that
3857 the rules can be aggressive yet still safe.
3862 * src/mcs51/peeph.def
3864 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3868 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3869 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3870 if the left or right operand symbols have the accuse flag set.
3872 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3874 Changed the type of the result of the ! (NOT) operator to char;
3875 previously it returned the same type as the source. This allows
3876 us to eliminate all the genFloatNot functions (all of its target
3877 implementations were very buggy) since !float can use the same
3880 * src/SDCCicode.c (ast2iCode): ! returns char

3882 * src/ds390/gen.c (genNot, genNotFloat),
3883 * src/z80/gen.c (genNot, genNotFloat),
3884 * src/pic/gen.c (genNot, genNotFloat),
3885 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3887 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3889 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3890 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3891 during interrupts. Ensure WSAVE is located at a shared bank address.
3892 2. Fixed page selection in some places
3893 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3894 the registers name strings.
3895 4. Fixed "signed / unsigned compare" compiler warnings.
3896 5. The PIC port manages its own allocation of the general purpose
3897 registers, but makes no attempt to reuse them. As a result when
3898 compiling it soon runs out of general purpose registers. Some
3899 additional code was added to the files pcode.c and device.c to walk
3900 through the function call tree and rename the registers so that they
3910 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3911 genPlus() & genMinus() when the result is the same as left or right

3917 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3919 Made bitfield a distinct type from bit so that bitfields
3920 convert as per ANSI C and bits retain their traditional
3921 boolean style behaviour. Implemented bitfield support in
3929 * src/ds390/gen.c: bit v bitfield split
3930 * src/z80/gen.c: New support for bitfields
3931 * support/regression/tests/bitfields.c: reenabled z80,
3934 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3936 Rules 246.x, 247.x relate to bitfields, the others speed up
3937 access to xdata mapped I/O devices.
3939 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3941 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3943 Cleaned up genPackBits and genUnpackBits and added two helper
3944 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3945 for literal assignments in genPackBits (thanks to Frieder for
3951 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3953 Fixed bug #748310 (pointer to function type mishandled when the
3954 function name is omitted). Also fixed a SIGSEGV when a function
3955 attribute (reentrant, etc) is used on a non-function or on a
3956 function but misplaced before the parameter list.
3958 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3960 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3961 * support/Util/SDCCerr.h,

3983 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3985 Made the constant following the "interrupt" keyword optional. If
3986 omitted, the function will not automatically be given an entry
3987 in the interrupt vector table (similar to #pragma NOIV, but
3988 less syntacticly kludgy). The interrupt number is also now
3989 range checked. Also fixed a bug in the high order bit example

4005 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4007 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4008 be re-activated by defining REDUCE_LITERALS)
4009 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4010 unsigned, but are signed by default
4011 * src/SDCCval.c (constVal): rearranged
4012 * src/SDCCval.c (valMod): preliminary fix
4013 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4465 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4466 the regression tests I'm not brave enough to enable 245.b, 245.c
4467 * doc/sdccman.lyx: added latex preamble for hyperref package.
4468 Using pdflatex this will give you a hyperlinked pdf file with
4469 bookmarks. (prepend '%' before /usepackage if this breaks something)

4507 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4509 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4510 it can be defined with CFLAGS when running configure
4511 * src/SDCCmain.c: fixed compiling + linking with object files
4513 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4516 added --disable-pic16-port
4517 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4518 * src/SDCCmain.c: linkOptions is changed to set *,
4519 added if/endif conditional macros to remove options help
4520 messages from optionsTable when a port is not configured, added
4521 support for the PIc16 port in the ports table, when executing
4522 the compiler with no port specified on command line, a default
4523 port is selected with the new macro DEFAULT_PORT which is
4524 defined in port.h, in setDefaultOptions() linkOptions is removed
4525 from initialization assignment, since now it is a set,
4526 parseCmdLine uses setParseWithComma for linkOptions, in
4527 linkEdit() linkOptions are accessed with new function indexSet()
4528 which returns the i'th item of a set variable. See SDCCset.c, in
4529 linkEdit() when calling buildCmdLine(), added linkOptions as
4530 last argument. Now users can pass arguments to gplink via the
4531 -Wl option, main() uses pic16glue() to glue up pic16 programs

4541 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4543 * src/pic16/glue.c: commented out some error producing lines
4544 * src/pic16/main.c: __config directives are commented out to stop
4545 gpasm complaining and test the linkage with gplink, _linkCmd and
4546 _asmCmd changed to be more gplink and gpasm friendly
4547 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4548 produced an error when parsed, peep rule 12 is added to utilize
4549 movff, but it is commented out since the pCode does not support
4550 yet a command with 2 address arguments
4552 2003-05-18 <johan AT balder>
4554 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4555 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4581 2003-05-11 Borut Razem <borut.razem AT siol.net>
4583 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4584 the path of bin directory, so that PATH is the only env. variable, which has to be set
4585 in case of standard installation.

5618 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5619 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5620 following files to include the previous two files: aslink.dsp,
5621 Makefile.aslink, Makefile.bcc, and Makefile.in.
5623 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5624 .adb instead of .cdb
5626 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5628 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5629 value from option --iram-size.
5631 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5633 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5636 2002-09-18 <wiml AT hhhh.org>
5638 * SDCClrange.h: exposed setFromRange() and setToRange()
5639 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5640 packRegsForAccUse() (bug 542397)
5641 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5642 multiple times and emitting the fetch operations more than once
5643 added aopGetUsesAcc() function to allow binary operators to
5644 fetch their operands in the correct order; made genMinus() emit
5645 compact code for X = LITERAL - Y
5647 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5648 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5649 sprintf() in line 1267.
5651 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5652 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5655 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5656 Changes to aslink (All the changes are marked with 'JCF'):
5658 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5661 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5662 area BSEG. Also moves, if possible, the DATA area down into the internal
5663 ram so more space is available.
5665 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5668 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5669 not bytes. Function summary() which creates a memory usage summary
5670 file with extension .mem. Reports of overlaping stack and small stack
5671 size. If the space for the stack is less than 16 bytes aslink trows a
5674 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5675 the 8051. Option 'y' for memory summary output file.
5677 Changes to sdcc (All the changes are marked with 'JCF'):
5679 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5681 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5682 overlaying area for it (uses RegBankUsed[4]).
5684 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5685 bank zero as used by default. By default aslink locates the stack
5686 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5687 the creation of the .mem file. Delegates the allocation of data area
5688 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5689 the begining of the stack area to aslink.
5691 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5692 glue() in SDCCglue.c creates an area for it.
5694 2002-09-03 Borut Razem <borut.razem AT siol.net>
5695 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5696 sdcc/src/pic/glue.c:
5697 introduced atexit() handler for teporay files removal in case of
5698 errors, assertions, ...
5700 2002-08-29 Borut Razem <borut.razem AT siol.net>
5701 * sdcc/support/cpp2/auto-host_vc_in.h:
5702 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5703 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5704 Maybe there is a similar problem with BORLANDC? It should be checked!
5706 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5707 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5708 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5709 was not executed, and the compiler (cl) launched a warning:
5710 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5712 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5713 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5715 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5716 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5718 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5719 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5720 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5721 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5722 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5723 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5724 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5725 - added Release configuration in VS projects
5726 - review of compiler an linker options
5727 - VC .exe files are generated in bin_vc directory, not to interfere
5728 with binaries generated from other projects (cygwin, mingw, bcc ...)
5730 * sdcc/src/yacc.dsp: added
5732 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5733 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5734 and insert the version number definitions from .version
5736 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5738 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

5748 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5750 2002-08-10 Borut Razem <borut.razem AT siol.net>
5751 * src/SDCCmain.c (main):
5752 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5753 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5754 The consequence was that some temporary files were not removed.
5757 unification of code in functions tempfilename() and tempfile():
5758 function tempnam() is defined in Visual Studio 6.0 and .NET
5760 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5762 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5763 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

5768 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5769 changed project type to Generic Project so that can be correcly converted to VS.NET project
5771 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5773 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5775 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5777 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5778 added return 0 statements after assert() to make compiler happy
5780 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5781 added newline in the def file to keep MSC compiler satisfied
5783 * sdcc/src/z80/gen.c:
5784 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5785 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5786 - solved MSC error in function aopDump()
5788 * sdcc_vc.h: define PREFIX as "\\sdcc"
5790 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5791 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5839 Added -p option. Allows port dependent processor to be specified.
5842 Initialized the new field char *Processor field to NULL in all ports
5845 Compiler generated registers for interrupt context saving
5846 were not getting allocated.
5848 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5851 Fixed left shift. Will promote the left side of a left shift
5852 if a) left shifting more than size of operand or b) when assigned
5853 to something size > size of left side
5855 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5963 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5965 * sdcc/src/SDCCloop.c:
5966 Previous fix was not good. basic blocks that have "break" or "return" are
5967 not really partof a loop , but live ranges used in these blocks should
5968 be live thru the entire loop, so set partOfLoop but don't add them to
5971 2002-02-21 <johan AT FRIJA>
5973 * src/SDCCcse.c: fixed bug #514308
5975 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
