2237 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2239 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2240 loaded with the linker search paths (-L arguments) and the libraries
2241 to be linked with the current source (-l arguments). Changes
2242 currently will affect only the pic16 port.
2243 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2244 include path the port specific paths and port specific libraries,
2245 * gplink command now contains the $3 argument,
2246 * src/pic16/device.h,
2247 * src/pic16/device.c,: structure PIC_device is made public and
2248 renamed to PIC16_device, the same for variable Pics which is renamed

2263 Documenting changes from previous commits.
2264 * configure.in (version 1.56),
2265 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2266 when generating output files to configure the pic16 library,
2267 but now I've commented it out, since gputils aren't installed in the
2268 SF compile farm, so library won't compile
2270 * device/lib/Makefile.in (version 1.56): initially I've added in
2271 target 'all' the prerequestive 'model-pic16' so it compiled the
2272 pic16 library, but now I've commented it out for the same reasons
2274 * added targets 'model-pic16' and 'objects-pic16' to compile the
2276 * added target 'port-specific-objects-pic16' to handle the
2277 generated libraries and copy them into the build/ directory
2278 * added target 'clean-intermediate-pic16' to clean intermediate
2279 files into pic16 directory
2280 * in target 'installdirs' added line to create directory pic16 in
2281 the installation path
2283 * device/include/Makefile.in (version 1.11): in target 'install'
2284 added lines to copy all header files to installation path,
2285 * in target 'installdirs' added line create directory for pic16
2286 headers in the installation path

2301 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2302 option so that it actually works. Made it specific to the z80, since
2303 the gbz80 doesn't have these kinds of I/O ports.
2305 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2307 * device/include/z180.h,

2331 via literal number. The symbol is placed in the corresponding
2332 position of the data ram
2333 * (pic16_dump_section): relocatable and absolute uninitialized
2334 data are now emitted in sorted order to reduce section naming,
2335 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2336 weren't marked as being in the access bank,
2338 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2340 Added portion of GNU PIC Library under the directory
2341 device/include/pic16 and device/lib/pic16. These files
2342 contain the declarations of SFRs for the PIC18Fxx2 devices.
2343 The directory is initialized via configure from toplevel.
2345 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
2347 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
2348 the spilllocations to be compared correctly
2350 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

2372 * doc/sdccman.lyx: Moved and added some sections, small changes
2373 all over. Telling LaTeX to be less strict with word spacing
2374 to better keep the right margin. Changed some notes about
2375 maintainance of the ports in section 3.2.1 - is it OK like this?
2377 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2415 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2417 * src/pic16/peeph.def: all peepholes with movff are commented out,
2418 because there is a problem in the pcode peep optimizer,
2419 * src/pic16/ralloc.c: the register allocator can now reuse local

2456 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2459 * src/z80/main.c: added missed needLinkerScript flags (more than
2460 one port structure defined in these file)
2461 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2496 2004-01-07 Borut Razem <borut.razem AT siol.net>
2498 * support/scripts/sdcc.nsi: update PATH
2499 * support/scripts/sdcc.ico: craeted

2512 include information about variables allocated to the overlay
2515 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2517 * as/mcs51/lkmain.c: Help about -Y option

2529 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2531 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2532 (default behaviour).
2534 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2536 A python script to validate compiler diagnostic messages. It can be
2537 used to verify that sdcc complains about bad c source code and
2538 gives a good location of the error.
2539 * support/valdiag/Makefile,
2540 * support/valdiag/valdiag.py,
2541 * support/valdiag/tests/*
2543 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2545 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

2556 * src/common.h: added ifndef/define/endif macros
2557 around the header file.
2558 Bug reported from Jesus Calvino-Fraga
2560 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2562 * sdcc.spec: updated
2563 * device/include/Makefile.in: don't install CVS directories
2564 * device/lib/Makefile.in: added removal of CVS directories after install
2565 * doc/Makefile: fixed install, added local_icons
2566 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2567 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2568 * src/ds390/gen.c (genRightShift): fixed bug #870788
2569 * src/SDCCast.c (decorateType): fixed bug #870781
2571 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2573 PIC16 port related changes:
2574 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2575 added variable stackPos,
2577 * gen.c: genCall, assignResultValue: added support for
2578 pushing/retrieving function parameters to/from stack,
2579 genFunction,genEndFunction: setup stack frame for the
2581 genAddrOf: will be changed according to bug 863624
2583 * added files genutils.c and genutils.h which contain gen*
2584 debugged and optimised functions extracted from gen.c
2586 * glue.c: added variable 'externs' which holds extern symbols,
2587 pic16emitRegularMap: is modified to properly handle relocatable
2588 symbols under the new scheme,
2589 pic16createInterruptVect: is modified
2590 pic16printPublics: is modified to emit 'global' assembler directives,
2591 added pic16_printExterns to print extern symbols,
2592 pic16glue: initializes stack/frame pointer in the beginning of
2593 the assembly output. Temporary hack, will be corrected later,
2594 because gplink yet does not support stack and SDCC does not
2595 yet support a type of crt0.o object to create the final binary.
2597 * Removed many lines that contain 8051 legacy code.
2598 * The code is finally placed under a 'code' directive.
2599 * Added port specific options.
2601 * _process_pragma: simplified since now we do not need *special*
2602 include file to define SFR registers. But a separate header
2603 will be needed. This will be developed later.
2604 * _pic16_parseOptions: added, parses port specific options:
2605 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2606 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2607 --preplace-udata-with=
2609 * _pic16_setDefaultOptions: modified to initialize section names,
2610 but hack is temporarly out of order since it needs improvement.
2611 * _pic16_genAssemblerPreamble: configuration words are emitted by
2612 their address instead of their name. This part is incomplete and
2613 supports only the 18Fxx2 devices. Other devices will emit an error
2614 during assembly since they do not contain the same set of config
2616 * _pic16_genIVT: is modified,
2618 * pcode.c: added definitions for some hardware registers that are needed
2620 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2621 All PCI entries are updated. Now LFSR is supported.
2622 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2623 * added pic16_newpCodeOpLit2 to support instructions with
2624 two literal arguments
2625 * pic16_pCode2str: corrected code that emits assembler instructions
2626 with two literal operands and those that have an access bit modifier
2627 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2628 this fixes a bug which caused some labels to be lost, when an
2629 assembler directive was added, i.e. banksel,
2630 * pic16_FixRegisterBanking: improved logic that causes the insertion
2632 * InlineFunction: functions that are called once, are not any more
2633 inlined. This can be a port option in the future,
2635 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2637 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2638 hold the corresponding uninitialized symbols,
2639 * pic16_allocProcessorRegister: registers have explicit marked the
2641 * pic16_allocInternalRegister: registers are explicit marked as
2643 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2644 processing list, so bit registers were lost,
2647 * ralloc.h: added field 'accessBank' and original symbol operand
2648 in register definition,
2649 * removed the field isMapped from register definition,
2651 ** Several functions have been removed from various sources:
2652 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2653 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2654 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2655 pic16_assignRelocatableRegisters
2657 ** others have been introduced:
2658 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2659 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2661 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2663 * support/scripts/inc2h.pl: changed definition of BIT_AT
2664 to emit 'sbit at' instead of 'bit at'. This was a request.
2666 PIC16 port related preliminary changes:
2667 * gen.c: prefixed function popRegFromString with
2668 pic16_ and all references to it corrected
2669 * pcode.c: all pic16_pc_* hardware registers prefixed
2670 with underscore (_),
2671 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2672 * ralloc.c: newReg(): when register is REG_SFR then
2673 set address to rIdx,
2674 pic16_allocProcessorRegister(): marks register wasUsed=0
2675 pic16_writeUsedRegs(): added a call to assign processor
2676 registers via pic16_assignFixedRegisters
2678 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2680 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2681 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2682 variables in unused register banks. Also the SSEG is placed
2683 wherever there is enough space for it, and IDATA can be anywhere
2684 in internal RAM. For now compile using -Wl-Y[stack_size].
2685 The mem file is different for this option as well, since it
2686 makes no sense of talking about DSEG lenght.
2688 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2690 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2691 in certain cases, e.g. when ROM assignment, patch provided
2692 from Albert den Haan.
2694 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3715 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3717 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3718 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3719 type for bits was changed. It resulted in bit variables becoming

3737 A few small changes that speed up the peephole optimizer.
3741 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3743 Try to make the peephole optimizer smarter by maintaining
3744 an association between the assembly source code and the
3745 iCodes that originated them. Put this information to use
3746 with a new peephole rule condition "notVolatile" so that
3747 the rules can be aggressive yet still safe.
3752 * src/mcs51/peeph.def
3754 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3758 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

3760 if the left or right operand symbols have the accuse flag set.
3762 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3764 Changed the type of the result of the ! (NOT) operator to char;
3765 previously it returned the same type as the source. This allows
3766 us to eliminate all the genFloatNot functions (all of its target
3767 implementations were very buggy) since !float can use the same
3770 * src/SDCCicode.c (ast2iCode): ! returns char

3779 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3780 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3781 during interrupts. Ensure WSAVE is located at a shared bank address.
3782 2. Fixed page selection in some places
3783 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3784 the registers name strings.
3785 4. Fixed "signed / unsigned compare" compiler warnings.
3786 5. The PIC port manages its own allocation of the general purpose
3787 registers, but makes no attempt to reuse them. As a result when
3788 compiling it soon runs out of general purpose registers. Some
3789 additional code was added to the files pcode.c and device.c to walk
3790 through the function call tree and rename the registers so that they
3800 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3809 Made bitfield a distinct type from bit so that bitfields
3810 convert as per ANSI C and bits retain their traditional
3811 boolean style behaviour. Implemented bitfield support in

3827 access to xdata mapped I/O devices.
3829 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3831 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3833 Cleaned up genPackBits and genUnpackBits and added two helper
3834 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3835 for literal assignments in genPackBits (thanks to Frieder for

3843 Fixed bug #748310 (pointer to function type mishandled when the
3844 function name is omitted). Also fixed a SIGSEGV when a function
3845 attribute (reentrant, etc) is used on a non-function or on a
3846 function but misplaced before the parameter list.

3875 Made the constant following the "interrupt" keyword optional. If
3876 omitted, the function will not automatically be given an entry
3877 in the interrupt vector table (similar to #pragma NOIV, but
3878 less syntacticly kludgy). The interrupt number is also now
3879 range checked. Also fixed a bug in the high order bit example

4399 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4400 it can be defined with CFLAGS when running configure
4401 * src/SDCCmain.c: fixed compiling + linking with object files
4403 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4405 * configure.in: configure for pic16 port,
4406 added --disable-pic16-port
4407 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4408 * src/SDCCmain.c: linkOptions is changed to set *,
4409 added if/endif conditional macros to remove options help
4410 messages from optionsTable when a port is not configured, added
4411 support for the PIc16 port in the ports table, when executing
4412 the compiler with no port specified on command line, a default
4413 port is selected with the new macro DEFAULT_PORT which is
4414 defined in port.h, in setDefaultOptions() linkOptions is removed
4415 from initialization assignment, since now it is a set,
4416 parseCmdLine uses setParseWithComma for linkOptions, in
4417 linkEdit() linkOptions are accessed with new function indexSet()
4418 which returns the i'th item of a set variable. See SDCCset.c, in
4419 linkEdit() when calling buildCmdLine(), added linkOptions as
4420 last argument. Now users can pass arguments to gplink via the
4421 -Wl option, main() uses pic16glue() to glue up pic16 programs

4433 * src/pic16/glue.c: commented out some error producing lines
4434 * src/pic16/main.c: __config directives are commented out to stop
4435 gpasm complaining and test the linkage with gplink, _linkCmd and
4436 _asmCmd changed to be more gplink and gpasm friendly
4437 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4438 produced an error when parsed, peep rule 12 is added to utilize
4439 movff, but it is commented out since the pCode does not support
4440 yet a command with 2 address arguments
4442 2003-05-18 <johan AT balder>
4444 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4471 2003-05-11 Borut Razem <borut.razem AT siol.net>
4473 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

5462 2003-01-07 <johan AT balder>
5464 * src/SDCCast.c (decorateType): fixed bug #600035

5479 * src/SDCCicode.c: fixed array add
5481 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5482 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5483 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5485 2003-01-04 <johan AT balder>
5487 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5489 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5490 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5492 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5493 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

5502 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5503 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5505 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5507 * in \sdcc\as\mcs51\ changed these files in order to create an
5508 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5509 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5510 following files to include the previous two files: aslink.dsp,
5511 Makefile.aslink, Makefile.bcc, and Makefile.in.
5513 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5514 .adb instead of .cdb
5516 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5518 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5519 value from option --iram-size.
5521 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5523 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5526 2002-09-18 <wiml AT hhhh.org>
5528 * SDCClrange.h: exposed setFromRange() and setToRange()
5529 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5530 packRegsForAccUse() (bug 542397)
5531 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5532 multiple times and emitting the fetch operations more than once
5533 added aopGetUsesAcc() function to allow binary operators to
5534 fetch their operands in the correct order; made genMinus() emit
5535 compact code for X = LITERAL - Y
5537 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5538 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5539 sprintf() in line 1267.
5541 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5542 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5545 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5546 Changes to aslink (All the changes are marked with 'JCF'):
5548 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5551 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5552 area BSEG. Also moves, if possible, the DATA area down into the internal
5553 ram so more space is available.
5555 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5558 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5559 not bytes. Function summary() which creates a memory usage summary
5560 file with extension .mem. Reports of overlaping stack and small stack
5561 size. If the space for the stack is less than 16 bytes aslink trows a
5564 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5565 the 8051. Option 'y' for memory summary output file.
5567 Changes to sdcc (All the changes are marked with 'JCF'):
5569 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5571 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5572 overlaying area for it (uses RegBankUsed[4]).
5574 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5575 bank zero as used by default. By default aslink locates the stack
5576 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5577 the creation of the .mem file. Delegates the allocation of data area
5578 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5579 the begining of the stack area to aslink.
5581 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5582 glue() in SDCCglue.c creates an area for it.
5584 2002-09-03 Borut Razem <borut.razem AT siol.net>
5585 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5586 sdcc/src/pic/glue.c:
5587 introduced atexit() handler for teporay files removal in case of
5588 errors, assertions, ...
5590 2002-08-29 Borut Razem <borut.razem AT siol.net>
5591 * sdcc/support/cpp2/auto-host_vc_in.h:
5592 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5593 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5594 Maybe there is a similar problem with BORLANDC? It should be checked!
5596 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5597 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5598 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5599 was not executed, and the compiler (cl) launched a warning:
5600 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5602 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5603 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5605 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5606 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5608 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5609 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5610 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5611 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5612 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5613 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5614 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5615 - added Release configuration in VS projects
5616 - review of compiler an linker options
5617 - VC .exe files are generated in bin_vc directory, not to interfere
5618 with binaries generated from other projects (cygwin, mingw, bcc ...)
5620 * sdcc/src/yacc.dsp: added
5622 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5623 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5624 and insert the version number definitions from .version
5626 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5628 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5629 added - genarate auto-host.h using auto-host_vc_in.h as template
5632 removed from CVS, generated automatically
5634 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5635 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5637 2002-08-11 Borut Razem <borut.razem AT siol.net>
5638 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5640 2002-08-10 Borut Razem <borut.razem AT siol.net>
5641 * src/SDCCmain.c (main):
5642 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5643 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5644 The consequence was that some temporary files were not removed.
5647 unification of code in functions tempfilename() and tempfile():
5648 function tempnam() is defined in Visual Studio 6.0 and .NET
5650 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5652 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5653 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5654 - removed compiler command line option /WX: Treats all warnings as errors
5655 - update a list of source files, included into the project
5657 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5658 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5659 changed project type to Generic Project so that can be correcly converted to VS.NET project
5661 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5663 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5665 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5667 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5668 added return 0 statements after assert() to make compiler happy
5670 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5671 added newline in the def file to keep MSC compiler satisfied
5673 * sdcc/src/z80/gen.c:
5674 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5675 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5676 - solved MSC error in function aopDump()
