2174 loaded with the linker search paths (-L arguments) and the libraries
2175 to be linked with the current source (-l arguments). Changes
2176 currently will affect only the pic16 port.
2177 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2178 include path the port specific paths and port specific libraries,
2179 * gplink command now contains the $3 argument,
2180 * src/pic16/device.h,

2197 Documenting changes from previous commits.
2198 * configure.in (version 1.56),
2199 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2200 when generating output files to configure the pic16 library,
2201 but now I've commented it out, since gputils aren't installed in the
2202 SF compile farm, so library won't compile
2204 * device/lib/Makefile.in (version 1.56): initially I've added in
2205 target 'all' the prerequestive 'model-pic16' so it compiled the
2206 pic16 library, but now I've commented it out for the same reasons
2208 * added targets 'model-pic16' and 'objects-pic16' to compile the
2210 * added target 'port-specific-objects-pic16' to handle the
2211 generated libraries and copy them into the build/ directory
2212 * added target 'clean-intermediate-pic16' to clean intermediate
2213 files into pic16 directory
2214 * in target 'installdirs' added line to create directory pic16 in

2236 option so that it actually works. Made it specific to the z80, since
2237 the gbz80 doesn't have these kinds of I/O ports.
2239 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2241 * device/include/z180.h,

2306 * doc/sdccman.lyx: Moved and added some sections, small changes
2307 all over. Telling LaTeX to be less strict with word spacing
2308 to better keep the right margin. Changed some notes about
2309 maintainance of the ports in section 3.2.1 - is it OK like this?
2311 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2313 SDCC source changes:
2314 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2348 UPPER for immediate operands,
2349 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2351 * src/pic16/peeph.def: all peepholes with movff are commented out,
2352 because there is a problem in the pcode peep optimizer,
2353 * src/pic16/ralloc.c: the register allocator can now reuse local

2446 include information about variables allocated to the overlay
2449 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2451 * as/mcs51/lkmain.c: Help about -Y option

2463 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2465 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2466 (default behaviour).
2468 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2470 A python script to validate compiler diagnostic messages. It can be
2471 used to verify that sdcc complains about bad c source code and
2472 gives a good location of the error.
2473 * support/valdiag/Makefile,
2474 * support/valdiag/valdiag.py,
2475 * support/valdiag/tests/*
2477 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2490 * src/common.h: added ifndef/define/endif macros
2491 around the header file.
2492 Bug reported from Jesus Calvino-Fraga
2494 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2496 * sdcc.spec: updated
2497 * device/include/Makefile.in: don't install CVS directories
2498 * device/lib/Makefile.in: added removal of CVS directories after install
2499 * doc/Makefile: fixed install, added local_icons
2500 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2501 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2502 * src/ds390/gen.c (genRightShift): fixed bug #870788
2503 * src/SDCCast.c (decorateType): fixed bug #870781
2505 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2507 PIC16 port related changes:
2508 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2509 added variable stackPos,
2511 * gen.c: genCall, assignResultValue: added support for
2512 pushing/retrieving function parameters to/from stack,
2513 genFunction,genEndFunction: setup stack frame for the
2515 genAddrOf: will be changed according to bug 863624
2517 * added files genutils.c and genutils.h which contain gen*
2518 debugged and optimised functions extracted from gen.c
2520 * glue.c: added variable 'externs' which holds extern symbols,
2521 pic16emitRegularMap: is modified to properly handle relocatable
2522 symbols under the new scheme,
2523 pic16createInterruptVect: is modified
2524 pic16printPublics: is modified to emit 'global' assembler directives,
2525 added pic16_printExterns to print extern symbols,
2526 pic16glue: initializes stack/frame pointer in the beginning of
2527 the assembly output. Temporary hack, will be corrected later,
2528 because gplink yet does not support stack and SDCC does not
2529 yet support a type of crt0.o object to create the final binary.
2531 * Removed many lines that contain 8051 legacy code.
2532 * The code is finally placed under a 'code' directive.
2533 * Added port specific options.
2535 * _process_pragma: simplified since now we do not need *special*
2536 include file to define SFR registers. But a separate header
2537 will be needed. This will be developed later.
2538 * _pic16_parseOptions: added, parses port specific options:
2539 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2540 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2541 --preplace-udata-with=
2543 * _pic16_setDefaultOptions: modified to initialize section names,
2544 but hack is temporarly out of order since it needs improvement.
2545 * _pic16_genAssemblerPreamble: configuration words are emitted by
2546 their address instead of their name. This part is incomplete and
2547 supports only the 18Fxx2 devices. Other devices will emit an error
2548 during assembly since they do not contain the same set of config
2550 * _pic16_genIVT: is modified,
2552 * pcode.c: added definitions for some hardware registers that are needed
2554 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2555 All PCI entries are updated. Now LFSR is supported.
2556 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2557 * added pic16_newpCodeOpLit2 to support instructions with
2558 two literal arguments
2559 * pic16_pCode2str: corrected code that emits assembler instructions
2560 with two literal operands and those that have an access bit modifier
2561 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2562 this fixes a bug which caused some labels to be lost, when an
2563 assembler directive was added, i.e. banksel,
2564 * pic16_FixRegisterBanking: improved logic that causes the insertion
2566 * InlineFunction: functions that are called once, are not any more
2567 inlined. This can be a port option in the future,
2569 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2571 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2572 hold the corresponding uninitialized symbols,
2573 * pic16_allocProcessorRegister: registers have explicit marked the
2575 * pic16_allocInternalRegister: registers are explicit marked as
2577 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2578 processing list, so bit registers were lost,
2581 * ralloc.h: added field 'accessBank' and original symbol operand
2582 in register definition,
2583 * removed the field isMapped from register definition,
2585 ** Several functions have been removed from various sources:
2586 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2587 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2588 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2589 pic16_assignRelocatableRegisters
2591 ** others have been introduced:
2592 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2593 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2595 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2597 * support/scripts/inc2h.pl: changed definition of BIT_AT
2598 to emit 'sbit at' instead of 'bit at'. This was a request.
2600 PIC16 port related preliminary changes:
2601 * gen.c: prefixed function popRegFromString with
2602 pic16_ and all references to it corrected
2603 * pcode.c: all pic16_pc_* hardware registers prefixed
2604 with underscore (_),
2605 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2606 * ralloc.c: newReg(): when register is REG_SFR then
2607 set address to rIdx,
2608 pic16_allocProcessorRegister(): marks register wasUsed=0
2609 pic16_writeUsedRegs(): added a call to assign processor
2610 registers via pic16_assignFixedRegisters
2612 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2614 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2615 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2616 variables in unused register banks. Also the SSEG is placed
2617 wherever there is enough space for it, and IDATA can be anywhere
2618 in internal RAM. For now compile using -Wl-Y[stack_size].
2619 The mem file is different for this option as well, since it
2620 makes no sense of talking about DSEG lenght.
2622 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2624 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2625 in certain cases, e.g. when ROM assignment, patch provided
2626 from Albert den Haan.
2628 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2771 * src/mcs51/peephole.def,
2772 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
2773 (allows non-interrupt and interrupt code to safely compete for a resource

3651 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3652 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

3671 A few small changes that speed up the peephole optimizer.
3675 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3677 Try to make the peephole optimizer smarter by maintaining
3678 an association between the assembly source code and the
3679 iCodes that originated them. Put this information to use
3680 with a new peephole rule condition "notVolatile" so that
3681 the rules can be aggressive yet still safe.
3686 * src/mcs51/peeph.def
3688 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3692 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3693 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3694 if the left or right operand symbols have the accuse flag set.
3696 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3698 Changed the type of the result of the ! (NOT) operator to char;
3699 previously it returned the same type as the source. This allows
3700 us to eliminate all the genFloatNot functions (all of its target
3701 implementations were very buggy) since !float can use the same
3704 * src/SDCCicode.c (ast2iCode): ! returns char

3713 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3714 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3715 during interrupts. Ensure WSAVE is located at a shared bank address.
3716 2. Fixed page selection in some places
3717 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3718 the registers name strings.
3719 4. Fixed "signed / unsigned compare" compiler warnings.
3720 5. The PIC port manages its own allocation of the general purpose
3721 registers, but makes no attempt to reuse them. As a result when
3722 compiling it soon runs out of general purpose registers. Some
3723 additional code was added to the files pcode.c and device.c to walk
3724 through the function call tree and rename the registers so that they
3734 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3735 genPlus() & genMinus() when the result is the same as left or right

3741 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3743 Made bitfield a distinct type from bit so that bitfields
3744 convert as per ANSI C and bits retain their traditional
3745 boolean style behaviour. Implemented bitfield support in
3753 * src/ds390/gen.c: bit v bitfield split
3754 * src/z80/gen.c: New support for bitfields
3755 * support/regression/tests/bitfields.c: reenabled z80,
3758 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3760 Rules 246.x, 247.x relate to bitfields, the others speed up
3761 access to xdata mapped I/O devices.
3763 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3765 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3767 Cleaned up genPackBits and genUnpackBits and added two helper

3777 Fixed bug #748310 (pointer to function type mishandled when the
3778 function name is omitted). Also fixed a SIGSEGV when a function
3779 attribute (reentrant, etc) is used on a non-function or on a
3780 function but misplaced before the parameter list.

3809 Made the constant following the "interrupt" keyword optional. If
3810 omitted, the function will not automatically be given an entry
3811 in the interrupt vector table (similar to #pragma NOIV, but
3812 less syntacticly kludgy). The interrupt number is also now
3813 range checked. Also fixed a bug in the high order bit example
3820 * support/Util/SDCCerr.c
3821 * support/Util/SDCCerr.h
3824 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

3833 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3834 unsigned, but are signed by default
3835 * src/SDCCval.c (constVal): rearranged
3836 * src/SDCCval.c (valMod): preliminary fix
3837 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3880 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
3881 * src/SDCCval.c (valDiv, valMod): fixed signdness
3882 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
3883 signedness of modulo, left and right shift
3884 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

4345 support for the PIc16 port in the ports table, when executing
4346 the compiler with no port specified on command line, a default
4347 port is selected with the new macro DEFAULT_PORT which is
4348 defined in port.h, in setDefaultOptions() linkOptions is removed
4349 from initialization assignment, since now it is a set,
4350 parseCmdLine uses setParseWithComma for linkOptions, in
4351 linkEdit() linkOptions are accessed with new function indexSet()
4352 which returns the i'th item of a set variable. See SDCCset.c, in
4353 linkEdit() when calling buildCmdLine(), added linkOptions as
4354 last argument. Now users can pass arguments to gplink via the

5419 2003-01-04 <johan AT balder>
5421 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5423 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5424 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5426 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5436 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5437 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5439 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5441 * in \sdcc\as\mcs51\ changed these files in order to create an
5442 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5443 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5444 following files to include the previous two files: aslink.dsp,
5445 Makefile.aslink, Makefile.bcc, and Makefile.in.
5447 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5448 .adb instead of .cdb
5450 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5452 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5453 value from option --iram-size.
5455 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5457 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5460 2002-09-18 <wiml AT hhhh.org>
5462 * SDCClrange.h: exposed setFromRange() and setToRange()
5463 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5464 packRegsForAccUse() (bug 542397)
5465 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5466 multiple times and emitting the fetch operations more than once
5467 added aopGetUsesAcc() function to allow binary operators to
5468 fetch their operands in the correct order; made genMinus() emit
5469 compact code for X = LITERAL - Y
5471 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5472 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5473 sprintf() in line 1267.
5475 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5476 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5479 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5480 Changes to aslink (All the changes are marked with 'JCF'):
5482 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5485 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5486 area BSEG. Also moves, if possible, the DATA area down into the internal
5487 ram so more space is available.
5489 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5492 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5493 not bytes. Function summary() which creates a memory usage summary
5494 file with extension .mem. Reports of overlaping stack and small stack
5495 size. If the space for the stack is less than 16 bytes aslink trows a
5498 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5499 the 8051. Option 'y' for memory summary output file.
5501 Changes to sdcc (All the changes are marked with 'JCF'):
5503 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5505 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5506 overlaying area for it (uses RegBankUsed[4]).
5508 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5509 bank zero as used by default. By default aslink locates the stack
5510 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5511 the creation of the .mem file. Delegates the allocation of data area
5512 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5513 the begining of the stack area to aslink.
5515 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5516 glue() in SDCCglue.c creates an area for it.
5518 2002-09-03 Borut Razem <borut.razem AT siol.net>
5519 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5520 sdcc/src/pic/glue.c:
5521 introduced atexit() handler for teporay files removal in case of
5522 errors, assertions, ...
5524 2002-08-29 Borut Razem <borut.razem AT siol.net>
5525 * sdcc/support/cpp2/auto-host_vc_in.h:
5526 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5527 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5528 Maybe there is a similar problem with BORLANDC? It should be checked!
5530 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5531 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5532 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5533 was not executed, and the compiler (cl) launched a warning:
5534 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5536 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5537 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5539 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5540 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5542 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5543 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5544 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5545 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5546 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5547 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5548 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5549 - added Release configuration in VS projects
5550 - review of compiler an linker options
5551 - VC .exe files are generated in bin_vc directory, not to interfere
5552 with binaries generated from other projects (cygwin, mingw, bcc ...)
5554 * sdcc/src/yacc.dsp: added
5556 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5557 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5558 and insert the version number definitions from .version
5560 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5562 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5563 added - genarate auto-host.h using auto-host_vc_in.h as template
5566 removed from CVS, generated automatically
5568 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5569 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5571 2002-08-11 Borut Razem <borut.razem AT siol.net>
5572 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5574 2002-08-10 Borut Razem <borut.razem AT siol.net>
5575 * src/SDCCmain.c (main):
5576 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5577 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5578 The consequence was that some temporary files were not removed.
5581 unification of code in functions tempfilename() and tempfile():
5582 function tempnam() is defined in Visual Studio 6.0 and .NET
5584 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5586 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5587 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5588 - removed compiler command line option /WX: Treats all warnings as errors
5589 - update a list of source files, included into the project
5591 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5592 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5593 changed project type to Generic Project so that can be correcly converted to VS.NET project
5595 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5597 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5599 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5601 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5602 added return 0 statements after assert() to make compiler happy
5604 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5605 added newline in the def file to keep MSC compiler satisfied
5607 * sdcc/src/z80/gen.c:
5608 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5609 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5610 - solved MSC error in function aopDump()
5612 * sdcc_vc.h: define PREFIX as "\\sdcc"
5614 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5615 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5617 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5618 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5619 - Rewrote the register banking algorithm.
5620 - Added pCode live-range analysis to registers (for now, only non-used and
5621 singly-used registers optimized away)
5623 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5625 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
5627 2002-05-10 Scott Dattalo <scott AT dattalo.com>
5628 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

5650 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
5652 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5654 2002-03-28 Johan Knol <johan AT balder>
5656 * src/SDCCval.c: fixed bug #532436
5658 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5660 Added "char *Processor" field to the port structure.
5663 Added -p option. Allows port dependent processor to be specified.
5666 Initialized the new field char *Processor field to NULL in all ports
5669 Compiler generated registers for interrupt context saving
5670 were not getting allocated.
5672 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5675 Fixed left shift. Will promote the left side of a left shift
5676 if a) left shifting more than size of operand or b) when assigned
5677 to something size > size of left side
5679 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5681 tons of changes. Register allocation has been
5682 rewritten. Added customization for the various PICs. Flow
5683 analysis is restructured. ...
5689 Added. device.c is a PIC port hack to accomodate variations
5692 2002-03-13 Michael Hope <michaelh AT vroom>
5694 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
5696 2002-03-04 johanknol <johanknol AT manik>
5698 * /src/SDCCval.c: fixed
5700 const unsigned char arr[][2] = { { 0, 1 } };
5701 t18.c:1: error: Initializer element is not constant
5703 2002-03-04 bela <bela AT manik>
5705 * /device/include/mcs51reg.h:
