2207 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2209 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2210 loaded with the linker search paths (-L arguments) and the libraries
2211 to be linked with the current source (-l arguments). Changes
2212 currently will affect only the pic16 port.
2213 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2214 include path the port specific paths and port specific libraries,
2215 * gplink command now contains the $3 argument,
2216 * src/pic16/device.h,
2217 * src/pic16/device.c,: structure PIC_device is made public and
2218 renamed to PIC16_device, the same for variable Pics which is renamed

2233 Documenting changes from previous commits.
2234 * configure.in (version 1.56),
2235 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2236 when generating output files to configure the pic16 library,
2237 but now I've commented it out, since gputils aren't installed in the
2238 SF compile farm, so library won't compile
2240 * device/lib/Makefile.in (version 1.56): initially I've added in
2241 target 'all' the prerequestive 'model-pic16' so it compiled the
2242 pic16 library, but now I've commented it out for the same reasons
2244 * added targets 'model-pic16' and 'objects-pic16' to compile the
2246 * added target 'port-specific-objects-pic16' to handle the
2247 generated libraries and copy them into the build/ directory
2248 * added target 'clean-intermediate-pic16' to clean intermediate
2249 files into pic16 directory
2250 * in target 'installdirs' added line to create directory pic16 in
2251 the installation path
2253 * device/include/Makefile.in (version 1.11): in target 'install'
2254 added lines to copy all header files to installation path,
2255 * in target 'installdirs' added line create directory for pic16
2256 headers in the installation path

2271 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2272 option so that it actually works. Made it specific to the z80, since
2273 the gbz80 doesn't have these kinds of I/O ports.
2275 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2277 * device/include/z180.h,

2301 via literal number. The symbol is placed in the corresponding
2302 position of the data ram
2303 * (pic16_dump_section): relocatable and absolute uninitialized
2304 data are now emitted in sorted order to reduce section naming,
2305 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2306 weren't marked as being in the access bank,
2308 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2310 Added portion of GNU PIC Library under the directory
2311 device/include/pic16 and device/lib/pic16. These files
2312 contain the declarations of SFRs for the PIC18Fxx2 devices.
2313 The directory is initialized via configure from toplevel.
2315 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

2343 all over. Telling LaTeX to be less strict with word spacing
2344 to better keep the right margin. Changed some notes about
2345 maintainance of the ports in section 3.2.1 - is it OK like this?
2347 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2385 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2387 * src/pic16/peeph.def: all peepholes with movff are commented out,
2388 because there is a problem in the pcode peep optimizer,
2389 * src/pic16/ralloc.c: the register allocator can now reuse local

2426 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2429 * src/z80/main.c: added missed needLinkerScript flags (more than
2430 one port structure defined in these file)
2431 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

2453 * (pic14emitOverlay): modified to emit a commented overlay segment
2454 directive when no overlay data exist
2455 * (picglue): modified to emit uninitialized data segment
2456 according to udata_section_name

2466 2004-01-07 Borut Razem <borut.razem AT siol.net>
2468 * support/scripts/sdcc.nsi: update PATH
2469 * support/scripts/sdcc.ico: craeted

2482 include information about variables allocated to the overlay
2485 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2487 * as/mcs51/lkmain.c: Help about -Y option

2499 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2501 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2502 (default behaviour).
2504 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2506 A python script to validate compiler diagnostic messages. It can be
2507 used to verify that sdcc complains about bad c source code and
2508 gives a good location of the error.
2509 * support/valdiag/Makefile,
2510 * support/valdiag/valdiag.py,
2511 * support/valdiag/tests/*
2513 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2526 * src/common.h: added ifndef/define/endif macros
2527 around the header file.
2528 Bug reported from Jesus Calvino-Fraga
2530 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2532 * sdcc.spec: updated
2533 * device/include/Makefile.in: don't install CVS directories
2534 * device/lib/Makefile.in: added removal of CVS directories after install
2535 * doc/Makefile: fixed install, added local_icons
2536 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2537 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2538 * src/ds390/gen.c (genRightShift): fixed bug #870788
2539 * src/SDCCast.c (decorateType): fixed bug #870781
2541 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2543 PIC16 port related changes:
2544 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2545 added variable stackPos,
2547 * gen.c: genCall, assignResultValue: added support for
2548 pushing/retrieving function parameters to/from stack,
2549 genFunction,genEndFunction: setup stack frame for the
2551 genAddrOf: will be changed according to bug 863624
2553 * added files genutils.c and genutils.h which contain gen*
2554 debugged and optimised functions extracted from gen.c
2556 * glue.c: added variable 'externs' which holds extern symbols,
2557 pic16emitRegularMap: is modified to properly handle relocatable
2558 symbols under the new scheme,
2559 pic16createInterruptVect: is modified
2560 pic16printPublics: is modified to emit 'global' assembler directives,
2561 added pic16_printExterns to print extern symbols,
2562 pic16glue: initializes stack/frame pointer in the beginning of
2563 the assembly output. Temporary hack, will be corrected later,
2564 because gplink yet does not support stack and SDCC does not
2565 yet support a type of crt0.o object to create the final binary.
2567 * Removed many lines that contain 8051 legacy code.
2568 * The code is finally placed under a 'code' directive.
2569 * Added port specific options.
2571 * _process_pragma: simplified since now we do not need *special*
2572 include file to define SFR registers. But a separate header
2573 will be needed. This will be developed later.
2574 * _pic16_parseOptions: added, parses port specific options:
2575 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2576 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2577 --preplace-udata-with=
2579 * _pic16_setDefaultOptions: modified to initialize section names,
2580 but hack is temporarly out of order since it needs improvement.
2581 * _pic16_genAssemblerPreamble: configuration words are emitted by
2582 their address instead of their name. This part is incomplete and
2583 supports only the 18Fxx2 devices. Other devices will emit an error
2584 during assembly since they do not contain the same set of config
2586 * _pic16_genIVT: is modified,
2588 * pcode.c: added definitions for some hardware registers that are needed
2590 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2591 All PCI entries are updated. Now LFSR is supported.
2592 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2593 * added pic16_newpCodeOpLit2 to support instructions with
2594 two literal arguments
2595 * pic16_pCode2str: corrected code that emits assembler instructions
2596 with two literal operands and those that have an access bit modifier
2597 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2598 this fixes a bug which caused some labels to be lost, when an
2599 assembler directive was added, i.e. banksel,
2600 * pic16_FixRegisterBanking: improved logic that causes the insertion
2602 * InlineFunction: functions that are called once, are not any more
2603 inlined. This can be a port option in the future,
2605 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2607 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2608 hold the corresponding uninitialized symbols,
2609 * pic16_allocProcessorRegister: registers have explicit marked the
2611 * pic16_allocInternalRegister: registers are explicit marked as
2613 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2614 processing list, so bit registers were lost,
2617 * ralloc.h: added field 'accessBank' and original symbol operand
2618 in register definition,
2619 * removed the field isMapped from register definition,
2621 ** Several functions have been removed from various sources:
2622 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2623 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2624 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2625 pic16_assignRelocatableRegisters
2627 ** others have been introduced:
2628 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2629 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2631 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2633 * support/scripts/inc2h.pl: changed definition of BIT_AT
2634 to emit 'sbit at' instead of 'bit at'. This was a request.
2636 PIC16 port related preliminary changes:
2637 * gen.c: prefixed function popRegFromString with
2638 pic16_ and all references to it corrected
2639 * pcode.c: all pic16_pc_* hardware registers prefixed
2640 with underscore (_),
2641 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2642 * ralloc.c: newReg(): when register is REG_SFR then
2643 set address to rIdx,
2644 pic16_allocProcessorRegister(): marks register wasUsed=0
2645 pic16_writeUsedRegs(): added a call to assign processor
2646 registers via pic16_assignFixedRegisters
2648 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2650 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2651 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2652 variables in unused register banks. Also the SSEG is placed
2653 wherever there is enough space for it, and IDATA can be anywhere
2654 in internal RAM. For now compile using -Wl-Y[stack_size].
2655 The mem file is different for this option as well, since it
2656 makes no sense of talking about DSEG lenght.
2658 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2660 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2661 in certain cases, e.g. when ROM assignment, patch provided
2662 from Albert den Haan.
2664 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3687 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3688 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3689 type for bits was changed. It resulted in bit variables becoming

3707 A few small changes that speed up the peephole optimizer.
3711 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3713 Try to make the peephole optimizer smarter by maintaining
3714 an association between the assembly source code and the
3715 iCodes that originated them. Put this information to use
3716 with a new peephole rule condition "notVolatile" so that
3717 the rules can be aggressive yet still safe.
3722 * src/mcs51/peeph.def
3724 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3728 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3729 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3730 if the left or right operand symbols have the accuse flag set.
3732 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3734 Changed the type of the result of the ! (NOT) operator to char;
3735 previously it returned the same type as the source. This allows
3736 us to eliminate all the genFloatNot functions (all of its target
3737 implementations were very buggy) since !float can use the same
3740 * src/SDCCicode.c (ast2iCode): ! returns char

3749 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3750 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3751 during interrupts. Ensure WSAVE is located at a shared bank address.
3752 2. Fixed page selection in some places
3753 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3754 the registers name strings.
3755 4. Fixed "signed / unsigned compare" compiler warnings.
3756 5. The PIC port manages its own allocation of the general purpose
3757 registers, but makes no attempt to reuse them. As a result when
3758 compiling it soon runs out of general purpose registers. Some
3759 additional code was added to the files pcode.c and device.c to walk
3760 through the function call tree and rename the registers so that they
3770 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3777 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3779 Made bitfield a distinct type from bit so that bitfields
3780 convert as per ANSI C and bits retain their traditional
3781 boolean style behaviour. Implemented bitfield support in
3789 * src/ds390/gen.c: bit v bitfield split
3790 * src/z80/gen.c: New support for bitfields
3791 * support/regression/tests/bitfields.c: reenabled z80,
3794 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3845 Made the constant following the "interrupt" keyword optional. If
3846 omitted, the function will not automatically be given an entry
3847 in the interrupt vector table (similar to #pragma NOIV, but
3848 less syntacticly kludgy). The interrupt number is also now
3849 range checked. Also fixed a bug in the high order bit example

4371 * src/SDCCmain.c: fixed compiling + linking with object files
4373 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4375 * configure.in: configure for pic16 port,
4376 added --disable-pic16-port
4377 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4378 * src/SDCCmain.c: linkOptions is changed to set *,
4379 added if/endif conditional macros to remove options help
4380 messages from optionsTable when a port is not configured, added
4381 support for the PIc16 port in the ports table, when executing
4382 the compiler with no port specified on command line, a default
4383 port is selected with the new macro DEFAULT_PORT which is
4384 defined in port.h, in setDefaultOptions() linkOptions is removed
4385 from initialization assignment, since now it is a set,
4386 parseCmdLine uses setParseWithComma for linkOptions, in
4387 linkEdit() linkOptions are accessed with new function indexSet()
4388 which returns the i'th item of a set variable. See SDCCset.c, in
4389 linkEdit() when calling buildCmdLine(), added linkOptions as
4390 last argument. Now users can pass arguments to gplink via the
4391 -Wl option, main() uses pic16glue() to glue up pic16 programs
4392 * src/SDCCpeeph.c: various changes to support pic16
4393 * src/SDCCset.c: added function void *indexSet(set *, int) to

4403 * src/pic16/glue.c: commented out some error producing lines
4404 * src/pic16/main.c: __config directives are commented out to stop
4405 gpasm complaining and test the linkage with gplink, _linkCmd and
4406 _asmCmd changed to be more gplink and gpasm friendly
4407 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4408 produced an error when parsed, peep rule 12 is added to utilize
4409 movff, but it is commented out since the pCode does not support
4410 yet a command with 2 address arguments
4412 2003-05-18 <johan AT balder>

4441 2003-05-11 Borut Razem <borut.razem AT siol.net>
4443 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

5449 * src/SDCCicode.c: fixed array add
5451 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5452 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5453 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5455 2003-01-04 <johan AT balder>
5457 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5459 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5460 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5462 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5472 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5473 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5475 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5477 * in \sdcc\as\mcs51\ changed these files in order to create an
5478 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5479 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5480 following files to include the previous two files: aslink.dsp,
5481 Makefile.aslink, Makefile.bcc, and Makefile.in.
5483 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5484 .adb instead of .cdb
5486 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5488 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5489 value from option --iram-size.
5491 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5493 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5496 2002-09-18 <wiml AT hhhh.org>
5498 * SDCClrange.h: exposed setFromRange() and setToRange()
5499 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5500 packRegsForAccUse() (bug 542397)
5501 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5502 multiple times and emitting the fetch operations more than once
5503 added aopGetUsesAcc() function to allow binary operators to
5504 fetch their operands in the correct order; made genMinus() emit
5505 compact code for X = LITERAL - Y
5507 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5508 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5509 sprintf() in line 1267.
5511 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5512 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5515 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5516 Changes to aslink (All the changes are marked with 'JCF'):
5518 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5521 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5522 area BSEG. Also moves, if possible, the DATA area down into the internal
5523 ram so more space is available.
5525 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5528 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5529 not bytes. Function summary() which creates a memory usage summary
5530 file with extension .mem. Reports of overlaping stack and small stack
5531 size. If the space for the stack is less than 16 bytes aslink trows a
5534 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5535 the 8051. Option 'y' for memory summary output file.
5537 Changes to sdcc (All the changes are marked with 'JCF'):
5539 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5541 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5542 overlaying area for it (uses RegBankUsed[4]).
5544 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5545 bank zero as used by default. By default aslink locates the stack
5546 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5547 the creation of the .mem file. Delegates the allocation of data area
5548 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5549 the begining of the stack area to aslink.
5551 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5552 glue() in SDCCglue.c creates an area for it.
5554 2002-09-03 Borut Razem <borut.razem AT siol.net>
5555 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5556 sdcc/src/pic/glue.c:
5557 introduced atexit() handler for teporay files removal in case of
5558 errors, assertions, ...
5560 2002-08-29 Borut Razem <borut.razem AT siol.net>
5561 * sdcc/support/cpp2/auto-host_vc_in.h:
5562 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5563 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5564 Maybe there is a similar problem with BORLANDC? It should be checked!
5566 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5567 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5568 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5569 was not executed, and the compiler (cl) launched a warning:
5570 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5572 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5573 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5575 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5576 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5578 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5579 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5580 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5581 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5582 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5583 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5584 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5585 - added Release configuration in VS projects
5586 - review of compiler an linker options
5587 - VC .exe files are generated in bin_vc directory, not to interfere
5588 with binaries generated from other projects (cygwin, mingw, bcc ...)
5590 * sdcc/src/yacc.dsp: added
5592 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5593 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5594 and insert the version number definitions from .version
5596 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5598 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5599 added - genarate auto-host.h using auto-host_vc_in.h as template
5602 removed from CVS, generated automatically
5604 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5605 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5607 2002-08-11 Borut Razem <borut.razem AT siol.net>
5608 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5610 2002-08-10 Borut Razem <borut.razem AT siol.net>
5611 * src/SDCCmain.c (main):
5612 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5613 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5614 The consequence was that some temporary files were not removed.
5617 unification of code in functions tempfilename() and tempfile():
5618 function tempnam() is defined in Visual Studio 6.0 and .NET
5620 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5622 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5623 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5624 - removed compiler command line option /WX: Treats all warnings as errors
5625 - update a list of source files, included into the project
5627 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5628 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5629 changed project type to Generic Project so that can be correcly converted to VS.NET project
5631 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5633 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5635 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5637 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5638 added return 0 statements after assert() to make compiler happy
5640 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5641 added newline in the def file to keep MSC compiler satisfied
5643 * sdcc/src/z80/gen.c:
5644 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5645 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5646 - solved MSC error in function aopDump()
5648 * sdcc_vc.h: define PREFIX as "\\sdcc"
5650 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5651 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5653 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5654 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5655 - Rewrote the register banking algorithm.
5656 - Added pCode live-range analysis to registers (for now, only non-used and
5657 singly-used registers optimized away)
5659 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5661 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
5663 2002-05-10 Scott Dattalo <scott AT dattalo.com>
5664 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
5666 2002-04-22 Michael Hope <michaelh AT vroom>
5668 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
5670 * configure.in (DD_COPT): Added include support required for gbdk.
