2095 loaded with the linker search paths (-L arguments) and the libraries
2096 to be linked with the current source (-l arguments). Changes
2097 currently will affect only the pic16 port.
2098 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2099 include path the port specific paths and port specific libraries,
2100 * gplink command now contains the $3 argument,
2101 * src/pic16/device.h,
2102 * src/pic16/device.c,: structure PIC_device is made public and

2118 Documenting changes from previous commits.
2119 * configure.in (version 1.56),
2120 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2121 when generating output files to configure the pic16 library,
2122 but now I've commented it out, since gputils aren't installed in the
2123 SF compile farm, so library won't compile
2125 * device/lib/Makefile.in (version 1.56): initially I've added in
2126 target 'all' the prerequestive 'model-pic16' so it compiled the
2127 pic16 library, but now I've commented it out for the same reasons
2129 * added targets 'model-pic16' and 'objects-pic16' to compile the
2131 * added target 'port-specific-objects-pic16' to handle the
2132 generated libraries and copy them into the build/ directory

2311 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2314 * src/z80/main.c: added missed needLinkerScript flags (more than
2315 one port structure defined in these file)
2316 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
2319 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

2322 * src/port.h: added flag needLinkerScript in port->linker
2323 structure to inform whether to create a .lnk file or not,
2331 * src/z80/main.c: changed appropriately to configure
2332 needLinkerScript flag
2334 * src/pic16/gen.c (genAddrOf): fixed bug #863624
2335 * src/pic/glue.c: added variable udata_section_name to
2336 override default uninitialized data segment definition for
2337 devices only with SHAREBANK memory (reported from Erik Epetrich)
2338 * (pic14emitOverlay): modified to emit a commented overlay segment
2339 directive when no overlay data exist
2340 * (picglue): modified to emit uninitialized data segment
2341 according to udata_section_name

2345 * modified _linkCmd and _asmCmd to include compiler passed
2346 arguments via -W option
2347 * src/pic16/main.c: added $l in _asmCmd, changed extension for
2348 object file from '.rel' to '.o' in port->linker structure,
2349 changed size of fptr from 2 to 3 in port structure
2351 2004-01-07 Borut Razem <borut.razem AT siol.net>
2353 * support/scripts/sdcc.nsi: update PATH
2354 * support/scripts/sdcc.ico: craeted

2367 include information about variables allocated to the overlay
2370 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2372 * as/mcs51/lkmain.c: Help about -Y option
2373 * as/mcs51/lkarea.c: Fixed gcc warnings
2375 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

2379 * support/valdiag/tests/overflow.c: added
2380 * src/SDCCast.c (decorateType),
2381 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
2382 LEFT_OP (left shift)
2384 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2386 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2387 (default behaviour).
2389 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2391 A python script to validate compiler diagnostic messages. It can be
2392 used to verify that sdcc complains about bad c source code and
2393 gives a good location of the error.
2394 * support/valdiag/Makefile,
2395 * support/valdiag/valdiag.py,
2396 * support/valdiag/tests/*
2398 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2409 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2411 * src/common.h: added ifndef/define/endif macros
2412 around the header file.
2413 Bug reported from Jesus Calvino-Fraga
2415 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2417 * sdcc.spec: updated
2418 * device/include/Makefile.in: don't install CVS directories
2419 * device/lib/Makefile.in: added removal of CVS directories after install
2420 * doc/Makefile: fixed install, added local_icons
2421 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2422 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2423 * src/ds390/gen.c (genRightShift): fixed bug #870788
2424 * src/SDCCast.c (decorateType): fixed bug #870781
2426 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2428 PIC16 port related changes:
2429 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2430 added variable stackPos,
2432 * gen.c: genCall, assignResultValue: added support for
2433 pushing/retrieving function parameters to/from stack,
2434 genFunction,genEndFunction: setup stack frame for the
2436 genAddrOf: will be changed according to bug 863624
2438 * added files genutils.c and genutils.h which contain gen*
2439 debugged and optimised functions extracted from gen.c
2441 * glue.c: added variable 'externs' which holds extern symbols,
2442 pic16emitRegularMap: is modified to properly handle relocatable
2443 symbols under the new scheme,
2444 pic16createInterruptVect: is modified
2445 pic16printPublics: is modified to emit 'global' assembler directives,
2446 added pic16_printExterns to print extern symbols,
2447 pic16glue: initializes stack/frame pointer in the beginning of
2448 the assembly output. Temporary hack, will be corrected later,
2449 because gplink yet does not support stack and SDCC does not
2450 yet support a type of crt0.o object to create the final binary.
2452 * Removed many lines that contain 8051 legacy code.
2453 * The code is finally placed under a 'code' directive.
2454 * Added port specific options.
2456 * _process_pragma: simplified since now we do not need *special*
2457 include file to define SFR registers. But a separate header
2458 will be needed. This will be developed later.
2459 * _pic16_parseOptions: added, parses port specific options:
2460 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2461 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2462 --preplace-udata-with=
2464 * _pic16_setDefaultOptions: modified to initialize section names,
2465 but hack is temporarly out of order since it needs improvement.
2466 * _pic16_genAssemblerPreamble: configuration words are emitted by
2467 their address instead of their name. This part is incomplete and
2468 supports only the 18Fxx2 devices. Other devices will emit an error
2469 during assembly since they do not contain the same set of config
2471 * _pic16_genIVT: is modified,
2473 * pcode.c: added definitions for some hardware registers that are needed
2475 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2476 All PCI entries are updated. Now LFSR is supported.
2477 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2478 * added pic16_newpCodeOpLit2 to support instructions with
2479 two literal arguments
2480 * pic16_pCode2str: corrected code that emits assembler instructions
2481 with two literal operands and those that have an access bit modifier
2482 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2483 this fixes a bug which caused some labels to be lost, when an
2484 assembler directive was added, i.e. banksel,
2485 * pic16_FixRegisterBanking: improved logic that causes the insertion
2487 * InlineFunction: functions that are called once, are not any more
2488 inlined. This can be a port option in the future,
2490 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2492 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2493 hold the corresponding uninitialized symbols,
2494 * pic16_allocProcessorRegister: registers have explicit marked the
2496 * pic16_allocInternalRegister: registers are explicit marked as
2498 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2499 processing list, so bit registers were lost,
2502 * ralloc.h: added field 'accessBank' and original symbol operand
2503 in register definition,
2504 * removed the field isMapped from register definition,
2506 ** Several functions have been removed from various sources:
2507 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2508 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2509 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2510 pic16_assignRelocatableRegisters
2512 ** others have been introduced:
2513 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2514 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2516 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2518 * support/scripts/inc2h.pl: changed definition of BIT_AT
2519 to emit 'sbit at' instead of 'bit at'. This was a request.
2521 PIC16 port related preliminary changes:
2522 * gen.c: prefixed function popRegFromString with
2523 pic16_ and all references to it corrected
2524 * pcode.c: all pic16_pc_* hardware registers prefixed
2525 with underscore (_),
2526 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2527 * ralloc.c: newReg(): when register is REG_SFR then
2528 set address to rIdx,
2529 pic16_allocProcessorRegister(): marks register wasUsed=0
2530 pic16_writeUsedRegs(): added a call to assign processor
2531 registers via pic16_assignFixedRegisters
2533 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2535 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2536 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2537 variables in unused register banks. Also the SSEG is placed
2538 wherever there is enough space for it, and IDATA can be anywhere
2539 in internal RAM. For now compile using -Wl-Y[stack_size].
2540 The mem file is different for this option as well, since it
2541 makes no sense of talking about DSEG lenght.
2543 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2545 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2546 in certain cases, e.g. when ROM assignment, patch provided
2547 from Albert den Haan.
2549 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2788 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2790 * src/SDCCast.c (decorateType): disabled a transformation I added in
2791 revision 1.188 (access to fields of a structure at an absolute address);

3551 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3552 fetching of the pointer
3553 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3554 copied from genNearPointerSet()
3555 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3556 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3572 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3573 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3574 type for bits was changed. It resulted in bit variables becoming
3575 global, which is not permitted in PIC 14 assembly output.
3577 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3592 A few small changes that speed up the peephole optimizer.
3596 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3598 Try to make the peephole optimizer smarter by maintaining
3599 an association between the assembly source code and the
3600 iCodes that originated them. Put this information to use
3601 with a new peephole rule condition "notVolatile" so that
3602 the rules can be aggressive yet still safe.
3607 * src/mcs51/peeph.def
3609 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3613 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3614 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3615 if the left or right operand symbols have the accuse flag set.
3617 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3619 Changed the type of the result of the ! (NOT) operator to char;
3620 previously it returned the same type as the source. This allows
3621 us to eliminate all the genFloatNot functions (all of its target
3622 implementations were very buggy) since !float can use the same
3625 * src/SDCCicode.c (ast2iCode): ! returns char

3634 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3635 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3636 during interrupts. Ensure WSAVE is located at a shared bank address.
3637 2. Fixed page selection in some places
3638 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3639 the registers name strings.
3640 4. Fixed "signed / unsigned compare" compiler warnings.
3641 5. The PIC port manages its own allocation of the general purpose
3642 registers, but makes no attempt to reuse them. As a result when
3643 compiling it soon runs out of general purpose registers. Some
3644 additional code was added to the files pcode.c and device.c to walk
3645 through the function call tree and rename the registers so that they
3655 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3662 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3664 Made bitfield a distinct type from bit so that bitfields
3665 convert as per ANSI C and bits retain their traditional
3666 boolean style behaviour. Implemented bitfield support in
3674 * src/ds390/gen.c: bit v bitfield split
3675 * src/z80/gen.c: New support for bitfields
3676 * support/regression/tests/bitfields.c: reenabled z80,
3679 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3681 Rules 246.x, 247.x relate to bitfields, the others speed up
3682 access to xdata mapped I/O devices.
3684 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3686 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3688 Cleaned up genPackBits and genUnpackBits and added two helper
3689 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3690 for literal assignments in genPackBits (thanks to Frieder for
3696 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3698 Fixed bug #748310 (pointer to function type mishandled when the
3699 function name is omitted). Also fixed a SIGSEGV when a function
3700 attribute (reentrant, etc) is used on a non-function or on a
3701 function but misplaced before the parameter list.
3703 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

3728 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3730 Made the constant following the "interrupt" keyword optional. If
3731 omitted, the function will not automatically be given an entry
3732 in the interrupt vector table (similar to #pragma NOIV, but
3733 less syntacticly kludgy). The interrupt number is also now
3734 range checked. Also fixed a bug in the high order bit example

4264 added if/endif conditional macros to remove options help
4265 messages from optionsTable when a port is not configured, added
4266 support for the PIc16 port in the ports table, when executing
4267 the compiler with no port specified on command line, a default
4268 port is selected with the new macro DEFAULT_PORT which is
4269 defined in port.h, in setDefaultOptions() linkOptions is removed
4270 from initialization assignment, since now it is a set,
4271 parseCmdLine uses setParseWithComma for linkOptions, in
4272 linkEdit() linkOptions are accessed with new function indexSet()
4273 which returns the i'th item of a set variable. See SDCCset.c, in
4274 linkEdit() when calling buildCmdLine(), added linkOptions as
4275 last argument. Now users can pass arguments to gplink via the
4276 -Wl option, main() uses pic16glue() to glue up pic16 programs

4290 gpasm complaining and test the linkage with gplink, _linkCmd and
4291 _asmCmd changed to be more gplink and gpasm friendly
4292 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4293 produced an error when parsed, peep rule 12 is added to utilize
4294 movff, but it is commented out since the pCode does not support
4295 yet a command with 2 address arguments
4297 2003-05-18 <johan AT balder>
4299 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4326 2003-05-11 Borut Razem <borut.razem AT siol.net>
4328 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

5332 2003-01-06 <johan AT balder>
5334 * src/SDCCicode.c: fixed array add
5336 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5337 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5338 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5340 2003-01-04 <johan AT balder>
5342 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5344 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5345 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5347 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5348 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

5357 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5358 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5360 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5362 * in \sdcc\as\mcs51\ changed these files in order to create an
5363 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5364 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5365 following files to include the previous two files: aslink.dsp,
5366 Makefile.aslink, Makefile.bcc, and Makefile.in.
5368 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5369 .adb instead of .cdb
5371 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5373 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5374 value from option --iram-size.
5376 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5378 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5381 2002-09-18 <wiml AT hhhh.org>
5383 * SDCClrange.h: exposed setFromRange() and setToRange()
5384 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5385 packRegsForAccUse() (bug 542397)
5386 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5387 multiple times and emitting the fetch operations more than once
5388 added aopGetUsesAcc() function to allow binary operators to
5389 fetch their operands in the correct order; made genMinus() emit
5390 compact code for X = LITERAL - Y
5392 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5393 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5394 sprintf() in line 1267.
5396 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5397 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5400 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5401 Changes to aslink (All the changes are marked with 'JCF'):
5403 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5406 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5407 area BSEG. Also moves, if possible, the DATA area down into the internal
5408 ram so more space is available.
5410 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5413 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5414 not bytes. Function summary() which creates a memory usage summary
5415 file with extension .mem. Reports of overlaping stack and small stack
5416 size. If the space for the stack is less than 16 bytes aslink trows a
5419 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5420 the 8051. Option 'y' for memory summary output file.
5422 Changes to sdcc (All the changes are marked with 'JCF'):
5424 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5426 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5427 overlaying area for it (uses RegBankUsed[4]).
5429 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5430 bank zero as used by default. By default aslink locates the stack
5431 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5432 the creation of the .mem file. Delegates the allocation of data area
5433 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5434 the begining of the stack area to aslink.
5436 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5437 glue() in SDCCglue.c creates an area for it.
5439 2002-09-03 Borut Razem <borut.razem AT siol.net>
5440 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5441 sdcc/src/pic/glue.c:
5442 introduced atexit() handler for teporay files removal in case of
5443 errors, assertions, ...
5445 2002-08-29 Borut Razem <borut.razem AT siol.net>
5446 * sdcc/support/cpp2/auto-host_vc_in.h:
5447 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5448 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5449 Maybe there is a similar problem with BORLANDC? It should be checked!
5451 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5452 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5453 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5454 was not executed, and the compiler (cl) launched a warning:
5455 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5457 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5458 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5460 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5461 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5463 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5464 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5465 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5466 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5467 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5468 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5469 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5470 - added Release configuration in VS projects
5471 - review of compiler an linker options
5472 - VC .exe files are generated in bin_vc directory, not to interfere
5473 with binaries generated from other projects (cygwin, mingw, bcc ...)
5475 * sdcc/src/yacc.dsp: added
5477 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5478 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5479 and insert the version number definitions from .version
5481 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5483 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5484 added - genarate auto-host.h using auto-host_vc_in.h as template
5487 removed from CVS, generated automatically
5489 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5490 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5492 2002-08-11 Borut Razem <borut.razem AT siol.net>
5493 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5495 2002-08-10 Borut Razem <borut.razem AT siol.net>
5496 * src/SDCCmain.c (main):
5497 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5498 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5499 The consequence was that some temporary files were not removed.
5502 unification of code in functions tempfilename() and tempfile():
5503 function tempnam() is defined in Visual Studio 6.0 and .NET
5505 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5507 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5508 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5509 - removed compiler command line option /WX: Treats all warnings as errors
5510 - update a list of source files, included into the project
5512 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5513 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5514 changed project type to Generic Project so that can be correcly converted to VS.NET project
5516 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5518 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5520 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5522 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5523 added return 0 statements after assert() to make compiler happy
5525 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5526 added newline in the def file to keep MSC compiler satisfied
5528 * sdcc/src/z80/gen.c:
5529 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5530 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5531 - solved MSC error in function aopDump()
5533 * sdcc_vc.h: define PREFIX as "\\sdcc"
5535 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5536 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5575 2002-03-28 Johan Knol <johan AT balder>
5577 * src/SDCCval.c: fixed bug #532436
5579 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5581 Added "char *Processor" field to the port structure.
5584 Added -p option. Allows port dependent processor to be specified.
5587 Initialized the new field char *Processor field to NULL in all ports
5590 Compiler generated registers for interrupt context saving
5591 were not getting allocated.
5593 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5596 Fixed left shift. Will promote the left side of a left shift
5597 if a) left shifting more than size of operand or b) when assigned
5598 to something size > size of left side
5600 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5602 tons of changes. Register allocation has been
5603 rewritten. Added customization for the various PICs. Flow
5604 analysis is restructured. ...
5610 Added. device.c is a PIC port hack to accomodate variations
5613 2002-03-13 Michael Hope <michaelh AT vroom>
5615 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
5617 2002-03-04 johanknol <johanknol AT manik>
5619 * /src/SDCCval.c: fixed
5621 const unsigned char arr[][2] = { { 0, 1 } };

5624 2002-03-04 bela <bela AT manik>
5626 * /device/include/mcs51reg.h:
5627 ds89c420 register definition update

5708 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5710 * sdcc/src/SDCCloop.c:
5711 Previous fix was not good. basic blocks that have "break" or "return" are
5712 not really partof a loop , but live ranges used in these blocks should
5713 be live thru the entire loop, so set partOfLoop but don't add them to
5716 2002-02-21 <johan AT FRIJA>
5718 * src/SDCCcse.c: fixed bug #514308
5720 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
5723 Fixed BUG #519583. If a conditional block ended in a return/break
5724 statement inside a loop, it was not being considered part of the loop.
5726 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5728 2002-02-10 Karl Bongers <karl AT turbobit.com>
5731 Fixed up SDCDB debugger somewhat. Updated debugger/README
5732 with lots of comments and notes.
5734 * device/examples/test2.c:
