2094 loaded with the linker search paths (-L arguments) and the libraries
2095 to be linked with the current source (-l arguments). Changes
2096 currently will affect only the pic16 port.
2097 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2098 include path the port specific paths and port specific libraries,
2099 * gplink command now contains the $3 argument,
2100 * src/pic16/device.h,

2117 Documenting changes from previous commits.
2118 * configure.in (version 1.56),
2119 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2120 when generating output files to configure the pic16 library,
2121 but now I've commented it out, since gputils aren't installed in the
2122 SF compile farm, so library won't compile
2124 * device/lib/Makefile.in (version 1.56): initially I've added in
2125 target 'all' the prerequestive 'model-pic16' so it compiled the
2126 pic16 library, but now I've commented it out for the same reasons
2128 * added targets 'model-pic16' and 'objects-pic16' to compile the
2130 * added target 'port-specific-objects-pic16' to handle the
2131 generated libraries and copy them into the build/ directory

2310 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2313 * src/z80/main.c: added missed needLinkerScript flags (more than
2314 one port structure defined in these file)
2315 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2318 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

2321 * src/port.h: added flag needLinkerScript in port->linker
2322 structure to inform whether to create a .lnk file or not,
2330 * src/z80/main.c: changed appropriately to configure
2331 needLinkerScript flag
2333 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2334 * src/pic/glue.c: added variable udata_section_name to
2335 override default uninitialized data segment definition for
2336 devices only with SHAREBANK memory (reported from Erik Epetrich)
2337 * (pic14emitOverlay): modified to emit a commented overlay segment
2338 directive when no overlay data exist
2339 * (picglue): modified to emit uninitialized data segment
2340 according to udata_section_name

2344 * modified _linkCmd and _asmCmd to include compiler passed
2345 arguments via -W option
2346 * src/pic16/main.c: added $l in _asmCmd, changed extension for
2347 object file from '.rel' to '.o' in port->linker structure,
2348 changed size of fptr from 2 to 3 in port structure
2350 2004-01-07 Borut Razem <borut.razem AT siol.net>
2352 * support/scripts/sdcc.nsi: update PATH
2353 * support/scripts/sdcc.ico: craeted

2366 include information about variables allocated to the overlay
2369 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2371 * as/mcs51/lkmain.c: Help about -Y option
2372 * as/mcs51/lkarea.c: Fixed gcc warnings
2374 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

2378 * support/valdiag/tests/overflow.c: added
2379 * src/SDCCast.c (decorateType),
2380 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
2381 LEFT_OP (left shift)
2383 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2385 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2386 (default behaviour).
2388 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2390 A python script to validate compiler diagnostic messages. It can be
2391 used to verify that sdcc complains about bad c source code and
2392 gives a good location of the error.
2393 * support/valdiag/Makefile,
2394 * support/valdiag/valdiag.py,
2395 * support/valdiag/tests/*
2397 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2408 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2410 * src/common.h: added ifndef/define/endif macros
2411 around the header file.
2412 Bug reported from Jesus Calvino-Fraga
2414 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2416 * sdcc.spec: updated
2417 * device/include/Makefile.in: don't install CVS directories
2418 * device/lib/Makefile.in: added removal of CVS directories after install
2419 * doc/Makefile: fixed install, added local_icons
2420 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2421 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2422 * src/ds390/gen.c (genRightShift): fixed bug #870788
2423 * src/SDCCast.c (decorateType): fixed bug #870781
2425 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2427 PIC16 port related changes:
2428 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2429 added variable stackPos,
2431 * gen.c: genCall, assignResultValue: added support for
2432 pushing/retrieving function parameters to/from stack,
2433 genFunction,genEndFunction: setup stack frame for the
2435 genAddrOf: will be changed according to bug 863624
2437 * added files genutils.c and genutils.h which contain gen*
2438 debugged and optimised functions extracted from gen.c
2440 * glue.c: added variable 'externs' which holds extern symbols,
2441 pic16emitRegularMap: is modified to properly handle relocatable
2442 symbols under the new scheme,
2443 pic16createInterruptVect: is modified
2444 pic16printPublics: is modified to emit 'global' assembler directives,
2445 added pic16_printExterns to print extern symbols,
2446 pic16glue: initializes stack/frame pointer in the beginning of
2447 the assembly output. Temporary hack, will be corrected later,
2448 because gplink yet does not support stack and SDCC does not
2449 yet support a type of crt0.o object to create the final binary.
2451 * Removed many lines that contain 8051 legacy code.
2452 * The code is finally placed under a 'code' directive.
2453 * Added port specific options.
2455 * _process_pragma: simplified since now we do not need *special*
2456 include file to define SFR registers. But a separate header
2457 will be needed. This will be developed later.
2458 * _pic16_parseOptions: added, parses port specific options:
2459 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2460 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2461 --preplace-udata-with=
2463 * _pic16_setDefaultOptions: modified to initialize section names,
2464 but hack is temporarly out of order since it needs improvement.
2465 * _pic16_genAssemblerPreamble: configuration words are emitted by
2466 their address instead of their name. This part is incomplete and
2467 supports only the 18Fxx2 devices. Other devices will emit an error
2468 during assembly since they do not contain the same set of config
2470 * _pic16_genIVT: is modified,
2472 * pcode.c: added definitions for some hardware registers that are needed
2474 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2475 All PCI entries are updated. Now LFSR is supported.
2476 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2477 * added pic16_newpCodeOpLit2 to support instructions with
2478 two literal arguments
2479 * pic16_pCode2str: corrected code that emits assembler instructions
2480 with two literal operands and those that have an access bit modifier
2481 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2482 this fixes a bug which caused some labels to be lost, when an
2483 assembler directive was added, i.e. banksel,
2484 * pic16_FixRegisterBanking: improved logic that causes the insertion
2486 * InlineFunction: functions that are called once, are not any more
2487 inlined. This can be a port option in the future,
2489 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2491 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2492 hold the corresponding uninitialized symbols,
2493 * pic16_allocProcessorRegister: registers have explicit marked the
2495 * pic16_allocInternalRegister: registers are explicit marked as
2497 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2498 processing list, so bit registers were lost,
2501 * ralloc.h: added field 'accessBank' and original symbol operand
2502 in register definition,
2503 * removed the field isMapped from register definition,
2505 ** Several functions have been removed from various sources:
2506 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2507 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2508 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2509 pic16_assignRelocatableRegisters
2511 ** others have been introduced:
2512 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2513 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2515 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2517 * support/scripts/inc2h.pl: changed definition of BIT_AT
2518 to emit 'sbit at' instead of 'bit at'. This was a request.
2520 PIC16 port related preliminary changes:
2521 * gen.c: prefixed function popRegFromString with
2522 pic16_ and all references to it corrected
2523 * pcode.c: all pic16_pc_* hardware registers prefixed
2524 with underscore (_),
2525 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2526 * ralloc.c: newReg(): when register is REG_SFR then
2527 set address to rIdx,
2528 pic16_allocProcessorRegister(): marks register wasUsed=0
2529 pic16_writeUsedRegs(): added a call to assign processor
2530 registers via pic16_assignFixedRegisters
2532 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2534 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2535 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2536 variables in unused register banks. Also the SSEG is placed
2537 wherever there is enough space for it, and IDATA can be anywhere
2538 in internal RAM. For now compile using -Wl-Y[stack_size].
2539 The mem file is different for this option as well, since it
2540 makes no sense of talking about DSEG lenght.
2542 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2544 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2545 in certain cases, e.g. when ROM assignment, patch provided
2546 from Albert den Haan.
2548 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2787 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2789 * src/SDCCast.c (decorateType): disabled a transformation I added in
2790 revision 1.188 (access to fields of a structure at an absolute address);

3550 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3551 fetching of the pointer
3552 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3553 copied from genNearPointerSet()
3554 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3555 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3571 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3572 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3573 type for bits was changed. It resulted in bit variables becoming
3574 global, which is not permitted in PIC 14 assembly output.

3591 A few small changes that speed up the peephole optimizer.
3595 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3597 Try to make the peephole optimizer smarter by maintaining
3598 an association between the assembly source code and the
3599 iCodes that originated them. Put this information to use
3600 with a new peephole rule condition "notVolatile" so that
3601 the rules can be aggressive yet still safe.
3606 * src/mcs51/peeph.def
3608 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3612 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3613 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3614 if the left or right operand symbols have the accuse flag set.
3616 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3618 Changed the type of the result of the ! (NOT) operator to char;
3619 previously it returned the same type as the source. This allows
3620 us to eliminate all the genFloatNot functions (all of its target
3621 implementations were very buggy) since !float can use the same

3633 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3634 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3635 during interrupts. Ensure WSAVE is located at a shared bank address.
3636 2. Fixed page selection in some places
3637 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3638 the registers name strings.
3639 4. Fixed "signed / unsigned compare" compiler warnings.
3640 5. The PIC port manages its own allocation of the general purpose
3641 registers, but makes no attempt to reuse them. As a result when
3642 compiling it soon runs out of general purpose registers. Some
3643 additional code was added to the files pcode.c and device.c to walk
3644 through the function call tree and rename the registers so that they
3654 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3661 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3663 Made bitfield a distinct type from bit so that bitfields
3664 convert as per ANSI C and bits retain their traditional
3665 boolean style behaviour. Implemented bitfield support in
3673 * src/ds390/gen.c: bit v bitfield split
3674 * src/z80/gen.c: New support for bitfields
3675 * support/regression/tests/bitfields.c: reenabled z80,
3678 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3680 Rules 246.x, 247.x relate to bitfields, the others speed up
3681 access to xdata mapped I/O devices.
3683 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3685 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3687 Cleaned up genPackBits and genUnpackBits and added two helper
3688 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3689 for literal assignments in genPackBits (thanks to Frieder for
3695 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3697 Fixed bug #748310 (pointer to function type mishandled when the
3698 function name is omitted). Also fixed a SIGSEGV when a function
3699 attribute (reentrant, etc) is used on a non-function or on a
3700 function but misplaced before the parameter list.

3727 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3729 Made the constant following the "interrupt" keyword optional. If
3730 omitted, the function will not automatically be given an entry
3731 in the interrupt vector table (similar to #pragma NOIV, but
3732 less syntacticly kludgy). The interrupt number is also now
3733 range checked. Also fixed a bug in the high order bit example

4263 added if/endif conditional macros to remove options help
4264 messages from optionsTable when a port is not configured, added
4265 support for the PIc16 port in the ports table, when executing
4266 the compiler with no port specified on command line, a default
4267 port is selected with the new macro DEFAULT_PORT which is
4268 defined in port.h, in setDefaultOptions() linkOptions is removed
4269 from initialization assignment, since now it is a set,
4270 parseCmdLine uses setParseWithComma for linkOptions, in
4271 linkEdit() linkOptions are accessed with new function indexSet()
4272 which returns the i'th item of a set variable. See SDCCset.c, in
4273 linkEdit() when calling buildCmdLine(), added linkOptions as
4274 last argument. Now users can pass arguments to gplink via the
4275 -Wl option, main() uses pic16glue() to glue up pic16 programs

4289 gpasm complaining and test the linkage with gplink, _linkCmd and
4290 _asmCmd changed to be more gplink and gpasm friendly
4291 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4292 produced an error when parsed, peep rule 12 is added to utilize
4293 movff, but it is commented out since the pCode does not support
4294 yet a command with 2 address arguments
4296 2003-05-18 <johan AT balder>
4298 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4325 2003-05-11 Borut Razem <borut.razem AT siol.net>
4327 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

5333 * src/SDCCicode.c: fixed array add
5335 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5336 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5337 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5339 2003-01-04 <johan AT balder>
5341 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5343 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5344 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5346 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5356 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5357 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5359 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5361 * in \sdcc\as\mcs51\ changed these files in order to create an
5362 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5363 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5364 following files to include the previous two files: aslink.dsp,
5365 Makefile.aslink, Makefile.bcc, and Makefile.in.
5367 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5368 .adb instead of .cdb
5370 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5372 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5373 value from option --iram-size.
5375 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5377 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5380 2002-09-18 <wiml AT hhhh.org>
5382 * SDCClrange.h: exposed setFromRange() and setToRange()
5383 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5384 packRegsForAccUse() (bug 542397)
5385 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5386 multiple times and emitting the fetch operations more than once
5387 added aopGetUsesAcc() function to allow binary operators to
5388 fetch their operands in the correct order; made genMinus() emit
5389 compact code for X = LITERAL - Y
5391 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5392 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5393 sprintf() in line 1267.
5395 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5396 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5399 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5400 Changes to aslink (All the changes are marked with 'JCF'):
5402 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5405 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5406 area BSEG. Also moves, if possible, the DATA area down into the internal
5407 ram so more space is available.
5409 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5412 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5413 not bytes. Function summary() which creates a memory usage summary
5414 file with extension .mem. Reports of overlaping stack and small stack
5415 size. If the space for the stack is less than 16 bytes aslink trows a
5418 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5419 the 8051. Option 'y' for memory summary output file.
5421 Changes to sdcc (All the changes are marked with 'JCF'):
5423 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5425 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5426 overlaying area for it (uses RegBankUsed[4]).
5428 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5429 bank zero as used by default. By default aslink locates the stack
5430 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5431 the creation of the .mem file. Delegates the allocation of data area
5432 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5433 the begining of the stack area to aslink.
5435 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5436 glue() in SDCCglue.c creates an area for it.
5438 2002-09-03 Borut Razem <borut.razem AT siol.net>
5439 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5440 sdcc/src/pic/glue.c:
5441 introduced atexit() handler for teporay files removal in case of
5442 errors, assertions, ...
5444 2002-08-29 Borut Razem <borut.razem AT siol.net>
5445 * sdcc/support/cpp2/auto-host_vc_in.h:
5446 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5447 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5448 Maybe there is a similar problem with BORLANDC? It should be checked!
5450 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5451 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5452 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5453 was not executed, and the compiler (cl) launched a warning:
5454 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5456 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5457 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5459 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5460 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5462 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5463 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5464 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5465 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5466 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5467 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5468 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5469 - added Release configuration in VS projects
5470 - review of compiler an linker options
5471 - VC .exe files are generated in bin_vc directory, not to interfere
5472 with binaries generated from other projects (cygwin, mingw, bcc ...)
5474 * sdcc/src/yacc.dsp: added
5476 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5477 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5478 and insert the version number definitions from .version
5480 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5482 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5483 added - genarate auto-host.h using auto-host_vc_in.h as template
5486 removed from CVS, generated automatically
5488 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5489 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5491 2002-08-11 Borut Razem <borut.razem AT siol.net>
5492 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5494 2002-08-10 Borut Razem <borut.razem AT siol.net>
5495 * src/SDCCmain.c (main):
5496 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5497 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5498 The consequence was that some temporary files were not removed.
5501 unification of code in functions tempfilename() and tempfile():
5502 function tempnam() is defined in Visual Studio 6.0 and .NET
5504 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5506 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5507 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5508 - removed compiler command line option /WX: Treats all warnings as errors
5509 - update a list of source files, included into the project
5511 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5512 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5513 changed project type to Generic Project so that can be correcly converted to VS.NET project
5515 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5517 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5519 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5521 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5522 added return 0 statements after assert() to make compiler happy
5524 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5525 added newline in the def file to keep MSC compiler satisfied
5527 * sdcc/src/z80/gen.c:
5528 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5529 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5530 - solved MSC error in function aopDump()
5532 * sdcc_vc.h: define PREFIX as "\\sdcc"
5534 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5535 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5572 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5574 2002-03-28 Johan Knol <johan AT balder>
5576 * src/SDCCval.c: fixed bug #532436
5578 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5580 Added "char *Processor" field to the port structure.
5583 Added -p option. Allows port dependent processor to be specified.
5586 Initialized the new field char *Processor field to NULL in all ports
5589 Compiler generated registers for interrupt context saving
5590 were not getting allocated.
5592 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5595 Fixed left shift. Will promote the left side of a left shift
5596 if a) left shifting more than size of operand or b) when assigned
5597 to something size > size of left side
5599 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5601 tons of changes. Register allocation has been
5602 rewritten. Added customization for the various PICs. Flow

5609 Added. device.c is a PIC port hack to accomodate variations
5612 2002-03-13 Michael Hope <michaelh AT vroom>
5614 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
5616 2002-03-04 johanknol <johanknol AT manik>
5618 * /src/SDCCval.c: fixed
5620 const unsigned char arr[][2] = { { 0, 1 } };

5623 2002-03-04 bela <bela AT manik>
5625 * /device/include/mcs51reg.h:
5626 ds89c420 register definition update

5707 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5709 * sdcc/src/SDCCloop.c:
5710 Previous fix was not good. basic blocks that have "break" or "return" are
5711 not really partof a loop , but live ranges used in these blocks should
5712 be live thru the entire loop, so set partOfLoop but don't add them to
5715 2002-02-21 <johan AT FRIJA>
5717 * src/SDCCcse.c: fixed bug #514308
5719 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
5722 Fixed BUG #519583. If a conditional block ended in a return/break
5723 statement inside a loop, it was not being considered part of the loop.
5725 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5727 2002-02-10 Karl Bongers <karl AT turbobit.com>
5730 Fixed up SDCDB debugger somewhat. Updated debugger/README
5731 with lots of comments and notes.
5733 * device/examples/test2.c:
