2175 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2177 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2178 loaded with the linker search paths (-L arguments) and the libraries
2179 to be linked with the current source (-l arguments). Changes
2180 currently will affect only the pic16 port.
2181 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2182 include path the port specific paths and port specific libraries,
2183 * gplink command now contains the $3 argument,
2184 * src/pic16/device.h,
2185 * src/pic16/device.c,: structure PIC_device is made public and
2186 renamed to PIC16_device, the same for variable Pics which is renamed

2201 Documenting changes from previous commits.
2202 * configure.in (version 1.56),
2203 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2204 when generating output files to configure the pic16 library,
2205 but now I've commented it out, since gputils aren't installed in the
2206 SF compile farm, so library won't compile
2208 * device/lib/Makefile.in (version 1.56): initially I've added in
2209 target 'all' the prerequestive 'model-pic16' so it compiled the
2210 pic16 library, but now I've commented it out for the same reasons
2212 * added targets 'model-pic16' and 'objects-pic16' to compile the
2214 * added target 'port-specific-objects-pic16' to handle the
2215 generated libraries and copy them into the build/ directory
2216 * added target 'clean-intermediate-pic16' to clean intermediate
2217 files into pic16 directory
2218 * in target 'installdirs' added line to create directory pic16 in
2219 the installation path

2222 added lines to copy all header files to installation path,
2223 * in target 'installdirs' added line create directory for pic16
2224 headers in the installation path

2239 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2240 option so that it actually works. Made it specific to the z80, since
2241 the gbz80 doesn't have these kinds of I/O ports.
2243 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2245 * device/include/z180.h,

2269 via literal number. The symbol is placed in the corresponding
2270 position of the data ram
2271 * (pic16_dump_section): relocatable and absolute uninitialized
2272 data are now emitted in sorted order to reduce section naming,
2273 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2274 weren't marked as being in the access bank,
2276 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2278 Added portion of GNU PIC Library under the directory
2279 device/include/pic16 and device/lib/pic16. These files
2280 contain the declarations of SFRs for the PIC18Fxx2 devices.
2281 The directory is initialized via configure from toplevel.

2308 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2310 * doc/sdccman.lyx: Moved and added some sections, small changes
2311 all over. Telling LaTeX to be less strict with word spacing
2312 to better keep the right margin. Changed some notes about
2313 maintainance of the ports in section 3.2.1 - is it OK like this?
2315 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
2317 SDCC source changes:
2318 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

2353 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2355 * src/pic16/peeph.def: all peepholes with movff are commented out,
2356 because there is a problem in the pcode peep optimizer,
2357 * src/pic16/ralloc.c: the register allocator can now reuse local

2434 2004-01-07 Borut Razem <borut.razem AT siol.net>
2436 * support/scripts/sdcc.nsi: update PATH
2437 * support/scripts/sdcc.ico: craeted

2467 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2469 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2470 (default behaviour).
2472 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2474 A python script to validate compiler diagnostic messages. It can be
2475 used to verify that sdcc complains about bad c source code and
2476 gives a good location of the error.
2477 * support/valdiag/Makefile,
2478 * support/valdiag/valdiag.py,
2479 * support/valdiag/tests/*

2494 * src/common.h: added ifndef/define/endif macros
2495 around the header file.
2496 Bug reported from Jesus Calvino-Fraga
2498 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2500 * sdcc.spec: updated
2501 * device/include/Makefile.in: don't install CVS directories
2502 * device/lib/Makefile.in: added removal of CVS directories after install
2503 * doc/Makefile: fixed install, added local_icons
2504 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2505 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2506 * src/ds390/gen.c (genRightShift): fixed bug #870788
2507 * src/SDCCast.c (decorateType): fixed bug #870781
2509 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2511 PIC16 port related changes:
2512 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2513 added variable stackPos,
2515 * gen.c: genCall, assignResultValue: added support for
2516 pushing/retrieving function parameters to/from stack,
2517 genFunction,genEndFunction: setup stack frame for the
2519 genAddrOf: will be changed according to bug 863624
2521 * added files genutils.c and genutils.h which contain gen*
2522 debugged and optimised functions extracted from gen.c
2524 * glue.c: added variable 'externs' which holds extern symbols,
2525 pic16emitRegularMap: is modified to properly handle relocatable
2526 symbols under the new scheme,
2527 pic16createInterruptVect: is modified
2528 pic16printPublics: is modified to emit 'global' assembler directives,
2529 added pic16_printExterns to print extern symbols,
2530 pic16glue: initializes stack/frame pointer in the beginning of
2531 the assembly output. Temporary hack, will be corrected later,
2532 because gplink yet does not support stack and SDCC does not
2533 yet support a type of crt0.o object to create the final binary.
2535 * Removed many lines that contain 8051 legacy code.
2536 * The code is finally placed under a 'code' directive.
2537 * Added port specific options.
2539 * _process_pragma: simplified since now we do not need *special*
2540 include file to define SFR registers. But a separate header
2541 will be needed. This will be developed later.
2542 * _pic16_parseOptions: added, parses port specific options:
2543 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2544 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2545 --preplace-udata-with=
2547 * _pic16_setDefaultOptions: modified to initialize section names,
2548 but hack is temporarly out of order since it needs improvement.
2549 * _pic16_genAssemblerPreamble: configuration words are emitted by
2550 their address instead of their name. This part is incomplete and
2551 supports only the 18Fxx2 devices. Other devices will emit an error
2552 during assembly since they do not contain the same set of config
2554 * _pic16_genIVT: is modified,
2556 * pcode.c: added definitions for some hardware registers that are needed
2558 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2559 All PCI entries are updated. Now LFSR is supported.
2560 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2561 * added pic16_newpCodeOpLit2 to support instructions with
2562 two literal arguments
2563 * pic16_pCode2str: corrected code that emits assembler instructions
2564 with two literal operands and those that have an access bit modifier
2565 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2566 this fixes a bug which caused some labels to be lost, when an
2567 assembler directive was added, i.e. banksel,
2568 * pic16_FixRegisterBanking: improved logic that causes the insertion
2570 * InlineFunction: functions that are called once, are not any more
2571 inlined. This can be a port option in the future,
2573 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2575 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2576 hold the corresponding uninitialized symbols,
2577 * pic16_allocProcessorRegister: registers have explicit marked the
2579 * pic16_allocInternalRegister: registers are explicit marked as
2581 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2582 processing list, so bit registers were lost,
2585 * ralloc.h: added field 'accessBank' and original symbol operand
2586 in register definition,
2587 * removed the field isMapped from register definition,
2589 ** Several functions have been removed from various sources:
2590 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2591 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2592 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2593 pic16_assignRelocatableRegisters
2595 ** others have been introduced:
2596 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2597 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2599 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2601 * support/scripts/inc2h.pl: changed definition of BIT_AT
2602 to emit 'sbit at' instead of 'bit at'. This was a request.
2604 PIC16 port related preliminary changes:
2605 * gen.c: prefixed function popRegFromString with
2606 pic16_ and all references to it corrected
2607 * pcode.c: all pic16_pc_* hardware registers prefixed
2608 with underscore (_),
2609 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2610 * ralloc.c: newReg(): when register is REG_SFR then
2611 set address to rIdx,
2612 pic16_allocProcessorRegister(): marks register wasUsed=0
2613 pic16_writeUsedRegs(): added a call to assign processor
2614 registers via pic16_assignFixedRegisters
2616 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2618 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2619 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2620 variables in unused register banks. Also the SSEG is placed
2621 wherever there is enough space for it, and IDATA can be anywhere
2622 in internal RAM. For now compile using -Wl-Y[stack_size].
2623 The mem file is different for this option as well, since it
2624 makes no sense of talking about DSEG lenght.
2626 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2628 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2629 in certain cases, e.g. when ROM assignment, patch provided
2630 from Albert den Haan.
2632 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2775 * src/mcs51/peephole.def,
2776 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
2777 (allows non-interrupt and interrupt code to safely compete for a resource

3655 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3656 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3657 type for bits was changed. It resulted in bit variables becoming

3675 A few small changes that speed up the peephole optimizer.
3679 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3681 Try to make the peephole optimizer smarter by maintaining
3682 an association between the assembly source code and the
3683 iCodes that originated them. Put this information to use
3684 with a new peephole rule condition "notVolatile" so that
3685 the rules can be aggressive yet still safe.
3690 * src/mcs51/peeph.def
3692 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3696 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3697 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3698 if the left or right operand symbols have the accuse flag set.
3700 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3702 Changed the type of the result of the ! (NOT) operator to char;
3703 previously it returned the same type as the source. This allows
3704 us to eliminate all the genFloatNot functions (all of its target
3705 implementations were very buggy) since !float can use the same
3708 * src/SDCCicode.c (ast2iCode): ! returns char

3717 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3718 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3719 during interrupts. Ensure WSAVE is located at a shared bank address.
3720 2. Fixed page selection in some places
3721 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3722 the registers name strings.
3723 4. Fixed "signed / unsigned compare" compiler warnings.
3724 5. The PIC port manages its own allocation of the general purpose
3725 registers, but makes no attempt to reuse them. As a result when
3726 compiling it soon runs out of general purpose registers. Some
3727 additional code was added to the files pcode.c and device.c to walk
3728 through the function call tree and rename the registers so that they
3738 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3745 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3747 Made bitfield a distinct type from bit so that bitfields
3748 convert as per ANSI C and bits retain their traditional
3749 boolean style behaviour. Implemented bitfield support in
3757 * src/ds390/gen.c: bit v bitfield split
3758 * src/z80/gen.c: New support for bitfields
3759 * support/regression/tests/bitfields.c: reenabled z80,
3762 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3764 Rules 246.x, 247.x relate to bitfields, the others speed up
3765 access to xdata mapped I/O devices.
3767 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3769 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3771 Cleaned up genPackBits and genUnpackBits and added two helper

3781 Fixed bug #748310 (pointer to function type mishandled when the
3782 function name is omitted). Also fixed a SIGSEGV when a function
3783 attribute (reentrant, etc) is used on a non-function or on a
3784 function but misplaced before the parameter list.

3811 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3813 Made the constant following the "interrupt" keyword optional. If
3814 omitted, the function will not automatically be given an entry
3815 in the interrupt vector table (similar to #pragma NOIV, but
3816 less syntacticly kludgy). The interrupt number is also now
3817 range checked. Also fixed a bug in the high order bit example
3824 * support/Util/SDCCerr.c
3825 * support/Util/SDCCerr.h

4347 added if/endif conditional macros to remove options help
4348 messages from optionsTable when a port is not configured, added
4349 support for the PIc16 port in the ports table, when executing
4350 the compiler with no port specified on command line, a default
4351 port is selected with the new macro DEFAULT_PORT which is
4352 defined in port.h, in setDefaultOptions() linkOptions is removed
4353 from initialization assignment, since now it is a set,
4354 parseCmdLine uses setParseWithComma for linkOptions, in
4355 linkEdit() linkOptions are accessed with new function indexSet()
4356 which returns the i'th item of a set variable. See SDCCset.c, in
4357 linkEdit() when calling buildCmdLine(), added linkOptions as
4358 last argument. Now users can pass arguments to gplink via the
4359 -Wl option, main() uses pic16glue() to glue up pic16 programs

5440 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5441 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5443 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5445 * in \sdcc\as\mcs51\ changed these files in order to create an
5446 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5447 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5448 following files to include the previous two files: aslink.dsp,
5449 Makefile.aslink, Makefile.bcc, and Makefile.in.
5451 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5452 .adb instead of .cdb
5454 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5456 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5457 value from option --iram-size.
5459 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5461 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5464 2002-09-18 <wiml AT hhhh.org>
5466 * SDCClrange.h: exposed setFromRange() and setToRange()
5467 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5468 packRegsForAccUse() (bug 542397)
5469 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5470 multiple times and emitting the fetch operations more than once
5471 added aopGetUsesAcc() function to allow binary operators to
5472 fetch their operands in the correct order; made genMinus() emit
5473 compact code for X = LITERAL - Y
5475 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5476 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5477 sprintf() in line 1267.
5479 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5480 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5483 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5484 Changes to aslink (All the changes are marked with 'JCF'):
5486 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5489 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5490 area BSEG. Also moves, if possible, the DATA area down into the internal
5491 ram so more space is available.
5493 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5496 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5497 not bytes. Function summary() which creates a memory usage summary
5498 file with extension .mem. Reports of overlaping stack and small stack
5499 size. If the space for the stack is less than 16 bytes aslink trows a
5502 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5503 the 8051. Option 'y' for memory summary output file.
5505 Changes to sdcc (All the changes are marked with 'JCF'):
5507 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5509 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5510 overlaying area for it (uses RegBankUsed[4]).
5512 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5513 bank zero as used by default. By default aslink locates the stack
5514 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5515 the creation of the .mem file. Delegates the allocation of data area
5516 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5517 the begining of the stack area to aslink.
5519 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5520 glue() in SDCCglue.c creates an area for it.
5522 2002-09-03 Borut Razem <borut.razem AT siol.net>
5523 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5524 sdcc/src/pic/glue.c:
5525 introduced atexit() handler for teporay files removal in case of
5526 errors, assertions, ...
5528 2002-08-29 Borut Razem <borut.razem AT siol.net>
5529 * sdcc/support/cpp2/auto-host_vc_in.h:
5530 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5531 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5532 Maybe there is a similar problem with BORLANDC? It should be checked!
5534 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5535 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5536 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5537 was not executed, and the compiler (cl) launched a warning:
5538 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5540 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5541 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5543 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5544 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5546 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5547 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5548 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5549 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5550 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5551 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5552 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5553 - added Release configuration in VS projects
5554 - review of compiler an linker options
5555 - VC .exe files are generated in bin_vc directory, not to interfere
5556 with binaries generated from other projects (cygwin, mingw, bcc ...)
5558 * sdcc/src/yacc.dsp: added
5560 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5561 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5562 and insert the version number definitions from .version
5564 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5566 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5567 added - genarate auto-host.h using auto-host_vc_in.h as template
5570 removed from CVS, generated automatically
5572 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5573 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5575 2002-08-11 Borut Razem <borut.razem AT siol.net>
5576 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5578 2002-08-10 Borut Razem <borut.razem AT siol.net>
5579 * src/SDCCmain.c (main):
5580 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5581 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5582 The consequence was that some temporary files were not removed.
5585 unification of code in functions tempfilename() and tempfile():
5586 function tempnam() is defined in Visual Studio 6.0 and .NET
5588 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5590 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5591 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5592 - removed compiler command line option /WX: Treats all warnings as errors
5593 - update a list of source files, included into the project
5595 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5596 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5597 changed project type to Generic Project so that can be correcly converted to VS.NET project
5599 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5601 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5603 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5605 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5606 added return 0 statements after assert() to make compiler happy
5608 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5609 added newline in the def file to keep MSC compiler satisfied
5611 * sdcc/src/z80/gen.c:
5612 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5613 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5614 - solved MSC error in function aopDump()
5616 * sdcc_vc.h: define PREFIX as "\\sdcc"
5618 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5619 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5621 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5622 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5623 - Rewrote the register banking algorithm.
5624 - Added pCode live-range analysis to registers (for now, only non-used and
5625 singly-used registers optimized away)
5627 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5629 * 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.
5631 2002-05-10 Scott Dattalo <scott AT dattalo.com>
5632 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

5654 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
5656 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5658 2002-03-28 Johan Knol <johan AT balder>
5660 * src/SDCCval.c: fixed bug #532436
5662 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5664 Added "char *Processor" field to the port structure.
5667 Added -p option. Allows port dependent processor to be specified.
5670 Initialized the new field char *Processor field to NULL in all ports
5673 Compiler generated registers for interrupt context saving
5674 were not getting allocated.
5676 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5679 Fixed left shift. Will promote the left side of a left shift
5680 if a) left shifting more than size of operand or b) when assigned
5681 to something size > size of left side
5683 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5685 tons of changes. Register allocation has been
5686 rewritten. Added customization for the various PICs. Flow
5687 analysis is restructured. ...
5693 Added. device.c is a PIC port hack to accomodate variations
5696 2002-03-13 Michael Hope <michaelh AT vroom>
5698 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
5700 2002-03-04 johanknol <johanknol AT manik>
5702 * /src/SDCCval.c: fixed
5704 const unsigned char arr[][2] = { { 0, 1 } };
