3008 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3009 loaded with the linker search paths (-L arguments) and the libraries
3010 to be linked with the current source (-l arguments). Changes
3011 currently will affect only the pic16 port.
3012 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3013 include path the port specific paths and port specific libraries,
3014 * gplink command now contains the $3 argument,
3015 * src/pic16/device.h,
3016 * src/pic16/device.c,: structure PIC_device is made public and

3032 Documenting changes from previous commits.
3033 * configure.in (version 1.56),
3034 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3035 when generating output files to configure the pic16 library,
3036 but now I've commented it out, since gputils aren't installed in the
3037 SF compile farm, so library won't compile
3039 * device/lib/Makefile.in (version 1.56): initially I've added in
3040 target 'all' the prerequestive 'model-pic16' so it compiled the
3041 pic16 library, but now I've commented it out for the same reasons
3043 * added targets 'model-pic16' and 'objects-pic16' to compile the
3045 * added target 'port-specific-objects-pic16' to handle the
3046 generated libraries and copy them into the build/ directory
3047 * added target 'clean-intermediate-pic16' to clean intermediate
3048 files into pic16 directory
3049 * in target 'installdirs' added line to create directory pic16 in

3053 added lines to copy all header files to installation path,
3054 * in target 'installdirs' added line create directory for pic16
3055 headers in the installation path

3071 option so that it actually works. Made it specific to the z80, since
3072 the gbz80 doesn't have these kinds of I/O ports.
3074 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3182 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
3183 UPPER for immediate operands,
3184 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3186 * src/pic16/peeph.def: all peepholes with movff are commented out,
3187 because there is a problem in the pcode peep optimizer,
3188 * src/pic16/ralloc.c: the register allocator can now reuse local
3189 function symbols for another function. This saves register usage.
3190 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3192 Added file src/pic16/NOTES with information about program writing on
3193 the current port version.

3281 include information about variables allocated to the overlay
3284 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3286 * as/mcs51/lkmain.c: Help about -Y option

3296 LEFT_OP (left shift)
3298 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3300 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3301 (default behaviour).
3303 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3305 A python script to validate compiler diagnostic messages. It can be
3306 used to verify that sdcc complains about bad c source code and
3307 gives a good location of the error.
3308 * support/valdiag/Makefile,
3309 * support/valdiag/valdiag.py,
3310 * support/valdiag/tests/*
3312 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3327 Bug reported from Jesus Calvino-Fraga
3329 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3331 * sdcc.spec: updated
3332 * device/include/Makefile.in: don't install CVS directories
3333 * device/lib/Makefile.in: added removal of CVS directories after install
3334 * doc/Makefile: fixed install, added local_icons
3335 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3336 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3337 * src/ds390/gen.c (genRightShift): fixed bug #870788

3340 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3342 PIC16 port related changes:
3343 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3344 added variable stackPos,
3346 * gen.c: genCall, assignResultValue: added support for
3347 pushing/retrieving function parameters to/from stack,
3348 genFunction,genEndFunction: setup stack frame for the
3350 genAddrOf: will be changed according to bug 863624
3352 * added files genutils.c and genutils.h which contain gen*
3353 debugged and optimised functions extracted from gen.c
3355 * glue.c: added variable 'externs' which holds extern symbols,
3356 pic16emitRegularMap: is modified to properly handle relocatable
3357 symbols under the new scheme,
3358 pic16createInterruptVect: is modified
3359 pic16printPublics: is modified to emit 'global' assembler directives,
3360 added pic16_printExterns to print extern symbols,
3361 pic16glue: initializes stack/frame pointer in the beginning of
3362 the assembly output. Temporary hack, will be corrected later,
3363 because gplink yet does not support stack and SDCC does not
3364 yet support a type of crt0.o object to create the final binary.
3366 * Removed many lines that contain 8051 legacy code.
3367 * The code is finally placed under a 'code' directive.
3368 * Added port specific options.
3370 * _process_pragma: simplified since now we do not need *special*
3371 include file to define SFR registers. But a separate header
3372 will be needed. This will be developed later.
3373 * _pic16_parseOptions: added, parses port specific options:
3374 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3375 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3376 --preplace-udata-with=
3378 * _pic16_setDefaultOptions: modified to initialize section names,
3379 but hack is temporarly out of order since it needs improvement.
3380 * _pic16_genAssemblerPreamble: configuration words are emitted by
3381 their address instead of their name. This part is incomplete and
3382 supports only the 18Fxx2 devices. Other devices will emit an error
3383 during assembly since they do not contain the same set of config
3385 * _pic16_genIVT: is modified,
3387 * pcode.c: added definitions for some hardware registers that are needed
3389 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3390 All PCI entries are updated. Now LFSR is supported.
3391 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3392 * added pic16_newpCodeOpLit2 to support instructions with
3393 two literal arguments
3394 * pic16_pCode2str: corrected code that emits assembler instructions
3395 with two literal operands and those that have an access bit modifier
3396 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3397 this fixes a bug which caused some labels to be lost, when an
3398 assembler directive was added, i.e. banksel,
3399 * pic16_FixRegisterBanking: improved logic that causes the insertion
3401 * InlineFunction: functions that are called once, are not any more
3402 inlined. This can be a port option in the future,
3404 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3406 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3407 hold the corresponding uninitialized symbols,
3408 * pic16_allocProcessorRegister: registers have explicit marked the
3410 * pic16_allocInternalRegister: registers are explicit marked as
3412 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3413 processing list, so bit registers were lost,
3416 * ralloc.h: added field 'accessBank' and original symbol operand
3417 in register definition,
3418 * removed the field isMapped from register definition,
3420 ** Several functions have been removed from various sources:
3421 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3422 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3423 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3424 pic16_assignRelocatableRegisters
3426 ** others have been introduced:
3427 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3428 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3430 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3432 * support/scripts/inc2h.pl: changed definition of BIT_AT
3433 to emit 'sbit at' instead of 'bit at'. This was a request.
3435 PIC16 port related preliminary changes:
3436 * gen.c: prefixed function popRegFromString with
3437 pic16_ and all references to it corrected
3438 * pcode.c: all pic16_pc_* hardware registers prefixed
3439 with underscore (_),
3440 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3441 * ralloc.c: newReg(): when register is REG_SFR then
3442 set address to rIdx,
3443 pic16_allocProcessorRegister(): marks register wasUsed=0
3444 pic16_writeUsedRegs(): added a call to assign processor
3445 registers via pic16_assignFixedRegisters
3447 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3449 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3450 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3451 variables in unused register banks. Also the SSEG is placed
3452 wherever there is enough space for it, and IDATA can be anywhere
3453 in internal RAM. For now compile using -Wl-Y[stack_size].
3454 The mem file is different for this option as well, since it
3455 makes no sense of talking about DSEG lenght.
3457 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3459 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3460 in certain cases, e.g. when ROM assignment, patch provided
3461 from Albert den Haan.
3463 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4465 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4466 fetching of the pointer
4467 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4468 copied from genNearPointerSet()
4469 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4470 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4486 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4487 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4488 type for bits was changed. It resulted in bit variables becoming
4489 global, which is not permitted in PIC 14 assembly output.

4506 A few small changes that speed up the peephole optimizer.
4510 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4512 Try to make the peephole optimizer smarter by maintaining
4513 an association between the assembly source code and the
4514 iCodes that originated them. Put this information to use
4515 with a new peephole rule condition "notVolatile" so that
4516 the rules can be aggressive yet still safe.
4521 * src/mcs51/peeph.def
4523 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4527 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4528 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4529 if the left or right operand symbols have the accuse flag set.
4531 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4533 Changed the type of the result of the ! (NOT) operator to char;
4534 previously it returned the same type as the source. This allows
4535 us to eliminate all the genFloatNot functions (all of its target
4536 implementations were very buggy) since !float can use the same

4548 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4549 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4550 during interrupts. Ensure WSAVE is located at a shared bank address.
4551 2. Fixed page selection in some places
4552 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4553 the registers name strings.
4554 4. Fixed "signed / unsigned compare" compiler warnings.
4555 5. The PIC port manages its own allocation of the general purpose
4556 registers, but makes no attempt to reuse them. As a result when
4557 compiling it soon runs out of general purpose registers. Some
4558 additional code was added to the files pcode.c and device.c to walk
4559 through the function call tree and rename the registers so that they
4569 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4576 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4578 Made bitfield a distinct type from bit so that bitfields
4579 convert as per ANSI C and bits retain their traditional
4580 boolean style behaviour. Implemented bitfield support in
4588 * src/ds390/gen.c: bit v bitfield split
4589 * src/z80/gen.c: New support for bitfields
4590 * support/regression/tests/bitfields.c: reenabled z80,
4593 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4595 Rules 246.x, 247.x relate to bitfields, the others speed up
4596 access to xdata mapped I/O devices.
4598 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4600 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4602 Cleaned up genPackBits and genUnpackBits and added two helper
4603 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4604 for literal assignments in genPackBits (thanks to Frieder for
4610 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4612 Fixed bug #748310 (pointer to function type mishandled when the
4613 function name is omitted). Also fixed a SIGSEGV when a function
4614 attribute (reentrant, etc) is used on a non-function or on a
4615 function but misplaced before the parameter list.
4617 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

4644 Made the constant following the "interrupt" keyword optional. If
4645 omitted, the function will not automatically be given an entry
4646 in the interrupt vector table (similar to #pragma NOIV, but
4647 less syntacticly kludgy). The interrupt number is also now
4648 range checked. Also fixed a bug in the high order bit example

5178 added if/endif conditional macros to remove options help
5179 messages from optionsTable when a port is not configured, added
5180 support for the PIc16 port in the ports table, when executing
5181 the compiler with no port specified on command line, a default
5182 port is selected with the new macro DEFAULT_PORT which is
5183 defined in port.h, in setDefaultOptions() linkOptions is removed
5184 from initialization assignment, since now it is a set,
5185 parseCmdLine uses setParseWithComma for linkOptions, in
5186 linkEdit() linkOptions are accessed with new function indexSet()
5187 which returns the i'th item of a set variable. See SDCCset.c, in
5188 linkEdit() when calling buildCmdLine(), added linkOptions as
5189 last argument. Now users can pass arguments to gplink via the
5190 -Wl option, main() uses pic16glue() to glue up pic16 programs

5203 * src/pic16/main.c: __config directives are commented out to stop
5204 gpasm complaining and test the linkage with gplink, _linkCmd and
5205 _asmCmd changed to be more gplink and gpasm friendly
5206 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5207 produced an error when parsed, peep rule 12 is added to utilize
5208 movff, but it is commented out since the pCode does not support
5209 yet a command with 2 address arguments
5211 2003-05-18 <johan AT balder>
5213 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5232 Fixed so you can set breakpoints prior to run, run does not stop
5233 on entry now. Add tbreak. Other enhancements and fixes for use
5236 2003-05-12 Borut Razem <borut.razem AT siol.net>
5238 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5240 2003-05-11 Borut Razem <borut.razem AT siol.net>
5242 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6248 * src/SDCCicode.c: fixed array add
6250 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6251 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6252 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6254 2003-01-04 <johan AT balder>
6256 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6258 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6259 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6261 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6262 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6271 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6272 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6274 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6276 * in \sdcc\as\mcs51\ changed these files in order to create an
6277 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6278 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6279 following files to include the previous two files: aslink.dsp,
6280 Makefile.aslink, Makefile.bcc, and Makefile.in.
6282 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6283 .adb instead of .cdb
6285 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6287 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6288 value from option --iram-size.
6290 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6292 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6295 2002-09-18 <wiml AT hhhh.org>
6297 * SDCClrange.h: exposed setFromRange() and setToRange()
6298 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6299 packRegsForAccUse() (bug 542397)
6300 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6301 multiple times and emitting the fetch operations more than once
6302 added aopGetUsesAcc() function to allow binary operators to
6303 fetch their operands in the correct order; made genMinus() emit
6304 compact code for X = LITERAL - Y
6306 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6307 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6308 sprintf() in line 1267.
6310 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6311 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6314 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6315 Changes to aslink (All the changes are marked with 'JCF'):
6317 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6320 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6321 area BSEG. Also moves, if possible, the DATA area down into the internal
6322 ram so more space is available.
6324 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6327 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6328 not bytes. Function summary() which creates a memory usage summary
6329 file with extension .mem. Reports of overlaping stack and small stack
6330 size. If the space for the stack is less than 16 bytes aslink trows a
6333 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6334 the 8051. Option 'y' for memory summary output file.
6336 Changes to sdcc (All the changes are marked with 'JCF'):
6338 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6340 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6341 overlaying area for it (uses RegBankUsed[4]).
6343 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6344 bank zero as used by default. By default aslink locates the stack
6345 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6346 the creation of the .mem file. Delegates the allocation of data area
6347 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6348 the begining of the stack area to aslink.
6350 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6351 glue() in SDCCglue.c creates an area for it.
6353 2002-09-03 Borut Razem <borut.razem AT siol.net>
6354 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6355 sdcc/src/pic/glue.c:
6356 introduced atexit() handler for teporay files removal in case of
6357 errors, assertions, ...
6359 2002-08-29 Borut Razem <borut.razem AT siol.net>
6360 * sdcc/support/cpp2/auto-host_vc_in.h:
6361 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6362 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6363 Maybe there is a similar problem with BORLANDC? It should be checked!
6365 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6366 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6367 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6368 was not executed, and the compiler (cl) launched a warning:
6369 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6371 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6372 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6374 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6375 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6377 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6378 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6379 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6380 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6381 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6382 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6383 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6384 - added Release configuration in VS projects
6385 - review of compiler an linker options
6386 - VC .exe files are generated in bin_vc directory, not to interfere
6387 with binaries generated from other projects (cygwin, mingw, bcc ...)
6389 * sdcc/src/yacc.dsp: added
6391 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6392 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6393 and insert the version number definitions from .version
6395 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6397 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6398 added - genarate auto-host.h using auto-host_vc_in.h as template
6401 removed from CVS, generated automatically
6403 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6404 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6406 2002-08-11 Borut Razem <borut.razem AT siol.net>
6407 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6409 2002-08-10 Borut Razem <borut.razem AT siol.net>
6410 * src/SDCCmain.c (main):
6411 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6412 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6413 The consequence was that some temporary files were not removed.
6416 unification of code in functions tempfilename() and tempfile():
6417 function tempnam() is defined in Visual Studio 6.0 and .NET
6419 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6421 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6422 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6423 - removed compiler command line option /WX: Treats all warnings as errors
6424 - update a list of source files, included into the project
6426 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6427 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6428 changed project type to Generic Project so that can be correcly converted to VS.NET project
6430 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6432 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6434 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6436 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6437 added return 0 statements after assert() to make compiler happy
6439 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6440 added newline in the def file to keep MSC compiler satisfied
6442 * sdcc/src/z80/gen.c:
6443 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6444 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6445 - solved MSC error in function aopDump()
6447 * sdcc_vc.h: define PREFIX as "\\sdcc"
6449 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6450 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6489 2002-03-28 Johan Knol <johan AT balder>
6491 * src/SDCCval.c: fixed bug #532436
6493 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6495 Added "char *Processor" field to the port structure.
6498 Added -p option. Allows port dependent processor to be specified.
6501 Initialized the new field char *Processor field to NULL in all ports
6504 Compiler generated registers for interrupt context saving
6505 were not getting allocated.
6507 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6510 Fixed left shift. Will promote the left side of a left shift
6511 if a) left shifting more than size of operand or b) when assigned
6512 to something size > size of left side
6514 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6516 tons of changes. Register allocation has been
6517 rewritten. Added customization for the various PICs. Flow

6625 Previous fix was not good. basic blocks that have "break" or "return" are
6626 not really partof a loop , but live ranges used in these blocks should
6627 be live thru the entire loop, so set partOfLoop but don't add them to
