2304 * src/pic/ralloc.h: applied patch from Slade Rich;
2305 added support for multiple code pages and multiple RAM banks on the
2306 PIC 14 port. The ASM files now no longer simply assume all the
2307 code / RAM are in the same page / bank. This means the linker can
2308 safely allocate code/RAM of separate ASM files to different pages/banks.
2309 * doc/sdccman.lyx: added Slade's tips
2310 * src/mcs51/peeph.def: fixed bug #880768

2319 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
2322 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
2323 strtof is not part of C89 and isn't included with Mac OS X.
2325 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2327 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
2328 shiftL2Left2Result): fixed bug #879326
2329 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

2352 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2354 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2355 loaded with the linker search paths (-L arguments) and the libraries
2356 to be linked with the current source (-l arguments). Changes
2357 currently will affect only the pic16 port.
2358 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2359 include path the port specific paths and port specific libraries,
2360 * gplink command now contains the $3 argument,
2361 * src/pic16/device.h,
2362 * src/pic16/device.c,: structure PIC_device is made public and
2363 renamed to PIC16_device, the same for variable Pics which is renamed
2364 to Pics16. Updated all references to them.
2365 * src/pic16/glue.c (pic16glue): corrected bug with code
2366 initialization which bypassed the variable initializations block.
2368 * device/lib/pic16/Makefile.rules: removed --penable-stack from
2369 COMPILE_FLAGS and added the --nostdinc option
2371 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2376 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
2378 Documenting changes from previous commits.
2379 * configure.in (version 1.56),
2380 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2381 when generating output files to configure the pic16 library,
2382 but now I've commented it out, since gputils aren't installed in the
2383 SF compile farm, so library won't compile
2385 * device/lib/Makefile.in (version 1.56): initially I've added in
2386 target 'all' the prerequestive 'model-pic16' so it compiled the
2387 pic16 library, but now I've commented it out for the same reasons
2389 * added targets 'model-pic16' and 'objects-pic16' to compile the
2391 * added target 'port-specific-objects-pic16' to handle the
2392 generated libraries and copy them into the build/ directory
2393 * added target 'clean-intermediate-pic16' to clean intermediate
2394 files into pic16 directory
2395 * in target 'installdirs' added line to create directory pic16 in
2396 the installation path
2398 * device/include/Makefile.in (version 1.11): in target 'install'
2399 added lines to copy all header files to installation path,
2400 * in target 'installdirs' added line create directory for pic16
2401 headers in the installation path

2416 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2417 option so that it actually works. Made it specific to the z80, since
2418 the gbz80 doesn't have these kinds of I/O ports.
2420 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2422 * device/include/z180.h,

2435 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2437 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
2438 changed interrupt vector table generation to only emit declared vectors.
2439 * device/include/Makefile.in: added missing backslash
2440 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

2444 Mainly changes to support compilation of the device libraries
2445 * src/pic16/device.c: stack is allocated via symbol and not
2446 via literal number. The symbol is placed in the corresponding
2447 position of the data ram
2448 * (pic16_dump_section): relocatable and absolute uninitialized
2449 data are now emitted in sorted order to reduce section naming,
2450 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2451 weren't marked as being in the access bank,
2453 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2455 Added portion of GNU PIC Library under the directory
2456 device/include/pic16 and device/lib/pic16. These files
2457 contain the declarations of SFRs for the PIC18Fxx2 devices.
2458 The directory is initialized via configure from toplevel.
2460 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2462 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2463 the spilllocations to be compared correctly

2488 all over. Telling LaTeX to be less strict with word spacing
2489 to better keep the right margin. Changed some notes about
2490 maintainance of the ports in section 3.2.1 - is it OK like this?
2492 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2530 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2532 * src/pic16/peeph.def: all peepholes with movff are commented out,
2533 because there is a problem in the pcode peep optimizer,
2534 * src/pic16/ralloc.c: the register allocator can now reuse local

2649 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2651 A python script to validate compiler diagnostic messages. It can be
2652 used to verify that sdcc complains about bad c source code and
2653 gives a good location of the error.
2654 * support/valdiag/Makefile,
2655 * support/valdiag/valdiag.py,
2656 * support/valdiag/tests/*

2686 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2688 PIC16 port related changes:
2689 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2690 added variable stackPos,
2692 * gen.c: genCall, assignResultValue: added support for
2693 pushing/retrieving function parameters to/from stack,
2694 genFunction,genEndFunction: setup stack frame for the
2696 genAddrOf: will be changed according to bug 863624
2698 * added files genutils.c and genutils.h which contain gen*
2699 debugged and optimised functions extracted from gen.c
2701 * glue.c: added variable 'externs' which holds extern symbols,
2702 pic16emitRegularMap: is modified to properly handle relocatable
2703 symbols under the new scheme,
2704 pic16createInterruptVect: is modified
2705 pic16printPublics: is modified to emit 'global' assembler directives,
2706 added pic16_printExterns to print extern symbols,
2707 pic16glue: initializes stack/frame pointer in the beginning of
2708 the assembly output. Temporary hack, will be corrected later,
2709 because gplink yet does not support stack and SDCC does not
2710 yet support a type of crt0.o object to create the final binary.
2712 * Removed many lines that contain 8051 legacy code.
2713 * The code is finally placed under a 'code' directive.
2714 * Added port specific options.
2716 * _process_pragma: simplified since now we do not need *special*
2717 include file to define SFR registers. But a separate header
2718 will be needed. This will be developed later.
2719 * _pic16_parseOptions: added, parses port specific options:
2720 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2721 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2722 --preplace-udata-with=
2724 * _pic16_setDefaultOptions: modified to initialize section names,
2725 but hack is temporarly out of order since it needs improvement.
2726 * _pic16_genAssemblerPreamble: configuration words are emitted by
2727 their address instead of their name. This part is incomplete and
2728 supports only the 18Fxx2 devices. Other devices will emit an error
2729 during assembly since they do not contain the same set of config
2731 * _pic16_genIVT: is modified,
2733 * pcode.c: added definitions for some hardware registers that are needed
2735 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2736 All PCI entries are updated. Now LFSR is supported.
2737 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2738 * added pic16_newpCodeOpLit2 to support instructions with
2739 two literal arguments
2740 * pic16_pCode2str: corrected code that emits assembler instructions
2741 with two literal operands and those that have an access bit modifier
2742 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2743 this fixes a bug which caused some labels to be lost, when an
2744 assembler directive was added, i.e. banksel,
2745 * pic16_FixRegisterBanking: improved logic that causes the insertion
2747 * InlineFunction: functions that are called once, are not any more
2748 inlined. This can be a port option in the future,
2750 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2752 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2753 hold the corresponding uninitialized symbols,
2754 * pic16_allocProcessorRegister: registers have explicit marked the
2756 * pic16_allocInternalRegister: registers are explicit marked as
2758 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2759 processing list, so bit registers were lost,
2762 * ralloc.h: added field 'accessBank' and original symbol operand
2763 in register definition,
2764 * removed the field isMapped from register definition,
2766 ** Several functions have been removed from various sources:
2767 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2768 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2769 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2770 pic16_assignRelocatableRegisters
2772 ** others have been introduced:
2773 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2774 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2776 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2778 * support/scripts/inc2h.pl: changed definition of BIT_AT
2779 to emit 'sbit at' instead of 'bit at'. This was a request.
2781 PIC16 port related preliminary changes:
2782 * gen.c: prefixed function popRegFromString with
2783 pic16_ and all references to it corrected
2784 * pcode.c: all pic16_pc_* hardware registers prefixed
2785 with underscore (_),
2786 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2787 * ralloc.c: newReg(): when register is REG_SFR then
2788 set address to rIdx,
2789 pic16_allocProcessorRegister(): marks register wasUsed=0
2790 pic16_writeUsedRegs(): added a call to assign processor
2791 registers via pic16_assignFixedRegisters
2793 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2795 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2796 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2797 variables in unused register banks. Also the SSEG is placed
2798 wherever there is enough space for it, and IDATA can be anywhere
2799 in internal RAM. For now compile using -Wl-Y[stack_size].
2800 The mem file is different for this option as well, since it
2801 makes no sense of talking about DSEG lenght.
2803 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

3796 and JUMPTABLE iCodes properly now (worked by accident before)
3797 * src/mcs51/gen.c (leftRightUseAcc),
3798 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3799 iCode properly now. Use getSize instead of nRegs since a & b
3800 aren't part of the nRegs tally.
3802 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3804 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

3810 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3811 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3812 fetching of the pointer
3813 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3814 copied from genNearPointerSet()
3815 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3816 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3817 If they pop r0/r1 they must be called in the opposite order than aopOp().
3818 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3819 (resp. --stack-auto), prepared for --xstack

3830 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3832 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3833 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3834 type for bits was changed. It resulted in bit variables becoming
3835 global, which is not permitted in PIC 14 assembly output.
3837 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3839 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3852 A few small changes that speed up the peephole optimizer.
3856 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3858 Try to make the peephole optimizer smarter by maintaining
3859 an association between the assembly source code and the
3860 iCodes that originated them. Put this information to use
3861 with a new peephole rule condition "notVolatile" so that
3862 the rules can be aggressive yet still safe.
3867 * src/mcs51/peeph.def
3869 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3873 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3874 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3875 if the left or right operand symbols have the accuse flag set.
3877 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3879 Changed the type of the result of the ! (NOT) operator to char;
3880 previously it returned the same type as the source. This allows
3881 us to eliminate all the genFloatNot functions (all of its target
3882 implementations were very buggy) since !float can use the same
3885 * src/SDCCicode.c (ast2iCode): ! returns char

3894 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3895 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3896 during interrupts. Ensure WSAVE is located at a shared bank address.
3897 2. Fixed page selection in some places
3898 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3899 the registers name strings.
3900 4. Fixed "signed / unsigned compare" compiler warnings.
3901 5. The PIC port manages its own allocation of the general purpose
3902 registers, but makes no attempt to reuse them. As a result when
3903 compiling it soon runs out of general purpose registers. Some
3904 additional code was added to the files pcode.c and device.c to walk
3905 through the function call tree and rename the registers so that they
3915 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3922 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3924 Made bitfield a distinct type from bit so that bitfields
3925 convert as per ANSI C and bits retain their traditional
3926 boolean style behaviour. Implemented bitfield support in
3934 * src/ds390/gen.c: bit v bitfield split
3935 * src/z80/gen.c: New support for bitfields
3936 * support/regression/tests/bitfields.c: reenabled z80,
3939 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3941 Rules 246.x, 247.x relate to bitfields, the others speed up
3942 access to xdata mapped I/O devices.
3944 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3946 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3948 Cleaned up genPackBits and genUnpackBits and added two helper
3949 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3950 for literal assignments in genPackBits (thanks to Frieder for
3956 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3958 Fixed bug #748310 (pointer to function type mishandled when the
3959 function name is omitted). Also fixed a SIGSEGV when a function
3960 attribute (reentrant, etc) is used on a non-function or on a
3961 function but misplaced before the parameter list.
3963 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3965 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3988 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3990 Made the constant following the "interrupt" keyword optional. If
3991 omitted, the function will not automatically be given an entry
3992 in the interrupt vector table (similar to #pragma NOIV, but
3993 less syntacticly kludgy). The interrupt number is also now
3994 range checked. Also fixed a bug in the high order bit example

4470 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4471 the regression tests I'm not brave enough to enable 245.b, 245.c
4472 * doc/sdccman.lyx: added latex preamble for hyperref package.
4473 Using pdflatex this will give you a hyperlinked pdf file with
4474 bookmarks. (prepend '%' before /usepackage if this breaks something)

4510 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
4512 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4514 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4515 it can be defined with CFLAGS when running configure
4516 * src/SDCCmain.c: fixed compiling + linking with object files
4518 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4520 * configure.in: configure for pic16 port,
4521 added --disable-pic16-port
4522 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4523 * src/SDCCmain.c: linkOptions is changed to set *,
4524 added if/endif conditional macros to remove options help
4525 messages from optionsTable when a port is not configured, added
4526 support for the PIc16 port in the ports table, when executing
4527 the compiler with no port specified on command line, a default
4528 port is selected with the new macro DEFAULT_PORT which is
4529 defined in port.h, in setDefaultOptions() linkOptions is removed
4530 from initialization assignment, since now it is a set,
4531 parseCmdLine uses setParseWithComma for linkOptions, in
4532 linkEdit() linkOptions are accessed with new function indexSet()
4533 which returns the i'th item of a set variable. See SDCCset.c, in
4534 linkEdit() when calling buildCmdLine(), added linkOptions as
4535 last argument. Now users can pass arguments to gplink via the
4536 -Wl option, main() uses pic16glue() to glue up pic16 programs
4537 * src/SDCCpeeph.c: various changes to support pic16
4538 * src/SDCCset.c: added function void *indexSet(set *, int) to
4539 return the i'th item of the set

4544 added macro DEFAULT_PORT
4545 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
4546 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4548 * src/pic16/glue.c: commented out some error producing lines
4549 * src/pic16/main.c: __config directives are commented out to stop
4550 gpasm complaining and test the linkage with gplink, _linkCmd and
4551 _asmCmd changed to be more gplink and gpasm friendly
4552 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4553 produced an error when parsed, peep rule 12 is added to utilize
4554 movff, but it is commented out since the pCode does not support
4555 yet a command with 2 address arguments
4557 2003-05-18 <johan AT balder>
4559 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4560 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4586 2003-05-11 Borut Razem <borut.razem AT siol.net>
4588 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4589 the path of bin directory, so that PATH is the only env. variable, which has to be set
4590 in case of standard installation.
4591 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5623 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5624 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5625 following files to include the previous two files: aslink.dsp,
5626 Makefile.aslink, Makefile.bcc, and Makefile.in.
5628 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5629 .adb instead of .cdb
5631 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5633 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5634 value from option --iram-size.
5636 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5638 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5641 2002-09-18 <wiml AT hhhh.org>
5643 * SDCClrange.h: exposed setFromRange() and setToRange()
5644 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5645 packRegsForAccUse() (bug 542397)
5646 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5647 multiple times and emitting the fetch operations more than once
5648 added aopGetUsesAcc() function to allow binary operators to
5649 fetch their operands in the correct order; made genMinus() emit
5650 compact code for X = LITERAL - Y
5652 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5653 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5654 sprintf() in line 1267.
5656 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5660 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5661 Changes to aslink (All the changes are marked with 'JCF'):
5663 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5666 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5667 area BSEG. Also moves, if possible, the DATA area down into the internal
5668 ram so more space is available.
5670 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5673 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5674 not bytes. Function summary() which creates a memory usage summary
5675 file with extension .mem. Reports of overlaping stack and small stack
5676 size. If the space for the stack is less than 16 bytes aslink trows a
5679 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5680 the 8051. Option 'y' for memory summary output file.
5682 Changes to sdcc (All the changes are marked with 'JCF'):
5684 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5686 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5687 overlaying area for it (uses RegBankUsed[4]).
5689 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5690 bank zero as used by default. By default aslink locates the stack
5691 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5692 the creation of the .mem file. Delegates the allocation of data area
5693 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5694 the begining of the stack area to aslink.
5696 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5697 glue() in SDCCglue.c creates an area for it.
5699 2002-09-03 Borut Razem <borut.razem AT siol.net>
5700 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5701 sdcc/src/pic/glue.c:
5702 introduced atexit() handler for teporay files removal in case of
5703 errors, assertions, ...
5705 2002-08-29 Borut Razem <borut.razem AT siol.net>
5706 * sdcc/support/cpp2/auto-host_vc_in.h:
5707 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5708 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5709 Maybe there is a similar problem with BORLANDC? It should be checked!
5711 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5712 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5713 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5714 was not executed, and the compiler (cl) launched a warning:
5715 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5717 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5718 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5720 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5721 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5723 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5724 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5725 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5726 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5727 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5728 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5729 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5730 - added Release configuration in VS projects
5731 - review of compiler an linker options
5732 - VC .exe files are generated in bin_vc directory, not to interfere
5733 with binaries generated from other projects (cygwin, mingw, bcc ...)
5735 * sdcc/src/yacc.dsp: added
5737 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5738 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5739 and insert the version number definitions from .version
5741 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5743 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

5752 2002-08-11 Borut Razem <borut.razem AT siol.net>
5753 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5755 2002-08-10 Borut Razem <borut.razem AT siol.net>
5756 * src/SDCCmain.c (main):
5757 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5758 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5759 The consequence was that some temporary files were not removed.
5762 unification of code in functions tempfilename() and tempfile():
5763 function tempnam() is defined in Visual Studio 6.0 and .NET
5765 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5767 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5768 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

5773 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5774 changed project type to Generic Project so that can be correcly converted to VS.NET project
5776 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5778 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5780 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5782 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5783 added return 0 statements after assert() to make compiler happy
5785 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5786 added newline in the def file to keep MSC compiler satisfied
5788 * sdcc/src/z80/gen.c:
5789 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5790 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5791 - solved MSC error in function aopDump()
5793 * sdcc_vc.h: define PREFIX as "\\sdcc"
5795 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5796 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5844 Added -p option. Allows port dependent processor to be specified.
5847 Initialized the new field char *Processor field to NULL in all ports
5850 Compiler generated registers for interrupt context saving
5851 were not getting allocated.
5853 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5856 Fixed left shift. Will promote the left side of a left shift
5857 if a) left shifting more than size of operand or b) when assigned
5858 to something size > size of left side
5860 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5968 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5970 * sdcc/src/SDCCloop.c:
5971 Previous fix was not good. basic blocks that have "break" or "return" are
5972 not really partof a loop , but live ranges used in these blocks should
5973 be live thru the entire loop, so set partOfLoop but don't add them to
5976 2002-02-21 <johan AT FRIJA>
5978 * src/SDCCcse.c: fixed bug #514308
5980 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
