2221 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2223 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2224 loaded with the linker search paths (-L arguments) and the libraries
2225 to be linked with the current source (-l arguments). Changes
2226 currently will affect only the pic16 port.
2227 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2228 include path the port specific paths and port specific libraries,
2229 * gplink command now contains the $3 argument,
2230 * src/pic16/device.h,
2231 * src/pic16/device.c,: structure PIC_device is made public and
2232 renamed to PIC16_device, the same for variable Pics which is renamed

2247 Documenting changes from previous commits.
2248 * configure.in (version 1.56),
2249 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2250 when generating output files to configure the pic16 library,
2251 but now I've commented it out, since gputils aren't installed in the
2252 SF compile farm, so library won't compile
2254 * device/lib/Makefile.in (version 1.56): initially I've added in
2255 target 'all' the prerequestive 'model-pic16' so it compiled the
2256 pic16 library, but now I've commented it out for the same reasons
2258 * added targets 'model-pic16' and 'objects-pic16' to compile the
2260 * added target 'port-specific-objects-pic16' to handle the
2261 generated libraries and copy them into the build/ directory
2262 * added target 'clean-intermediate-pic16' to clean intermediate
2263 files into pic16 directory
2264 * in target 'installdirs' added line to create directory pic16 in
2265 the installation path
2267 * device/include/Makefile.in (version 1.11): in target 'install'
2268 added lines to copy all header files to installation path,
2269 * in target 'installdirs' added line create directory for pic16
2270 headers in the installation path

2285 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2286 option so that it actually works. Made it specific to the z80, since
2287 the gbz80 doesn't have these kinds of I/O ports.
2289 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2291 * device/include/z180.h,

2357 all over. Telling LaTeX to be less strict with word spacing
2358 to better keep the right margin. Changed some notes about
2359 maintainance of the ports in section 3.2.1 - is it OK like this?
2361 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2401 * src/pic16/peeph.def: all peepholes with movff are commented out,
2402 because there is a problem in the pcode peep optimizer,
2403 * src/pic16/ralloc.c: the register allocator can now reuse local

2496 include information about variables allocated to the overlay
2499 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2501 * as/mcs51/lkmain.c: Help about -Y option

2513 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2515 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2516 (default behaviour).
2518 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2520 A python script to validate compiler diagnostic messages. It can be
2521 used to verify that sdcc complains about bad c source code and
2522 gives a good location of the error.
2523 * support/valdiag/Makefile,
2524 * support/valdiag/valdiag.py,
2525 * support/valdiag/tests/*
2527 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2540 * src/common.h: added ifndef/define/endif macros
2541 around the header file.
2542 Bug reported from Jesus Calvino-Fraga
2544 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2546 * sdcc.spec: updated
2547 * device/include/Makefile.in: don't install CVS directories
2548 * device/lib/Makefile.in: added removal of CVS directories after install
2549 * doc/Makefile: fixed install, added local_icons
2550 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2551 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2552 * src/ds390/gen.c (genRightShift): fixed bug #870788
2553 * src/SDCCast.c (decorateType): fixed bug #870781
2555 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2557 PIC16 port related changes:
2558 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2559 added variable stackPos,
2561 * gen.c: genCall, assignResultValue: added support for
2562 pushing/retrieving function parameters to/from stack,
2563 genFunction,genEndFunction: setup stack frame for the
2565 genAddrOf: will be changed according to bug 863624
2567 * added files genutils.c and genutils.h which contain gen*
2568 debugged and optimised functions extracted from gen.c
2570 * glue.c: added variable 'externs' which holds extern symbols,
2571 pic16emitRegularMap: is modified to properly handle relocatable
2572 symbols under the new scheme,
2573 pic16createInterruptVect: is modified
2574 pic16printPublics: is modified to emit 'global' assembler directives,
2575 added pic16_printExterns to print extern symbols,
2576 pic16glue: initializes stack/frame pointer in the beginning of
2577 the assembly output. Temporary hack, will be corrected later,
2578 because gplink yet does not support stack and SDCC does not
2579 yet support a type of crt0.o object to create the final binary.
2581 * Removed many lines that contain 8051 legacy code.
2582 * The code is finally placed under a 'code' directive.
2583 * Added port specific options.
2585 * _process_pragma: simplified since now we do not need *special*
2586 include file to define SFR registers. But a separate header
2587 will be needed. This will be developed later.
2588 * _pic16_parseOptions: added, parses port specific options:
2589 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2590 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2591 --preplace-udata-with=
2593 * _pic16_setDefaultOptions: modified to initialize section names,
2594 but hack is temporarly out of order since it needs improvement.
2595 * _pic16_genAssemblerPreamble: configuration words are emitted by
2596 their address instead of their name. This part is incomplete and
2597 supports only the 18Fxx2 devices. Other devices will emit an error
2598 during assembly since they do not contain the same set of config
2600 * _pic16_genIVT: is modified,
2602 * pcode.c: added definitions for some hardware registers that are needed
2604 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2605 All PCI entries are updated. Now LFSR is supported.
2606 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2607 * added pic16_newpCodeOpLit2 to support instructions with
2608 two literal arguments
2609 * pic16_pCode2str: corrected code that emits assembler instructions
2610 with two literal operands and those that have an access bit modifier
2611 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2612 this fixes a bug which caused some labels to be lost, when an
2613 assembler directive was added, i.e. banksel,
2614 * pic16_FixRegisterBanking: improved logic that causes the insertion
2616 * InlineFunction: functions that are called once, are not any more
2617 inlined. This can be a port option in the future,
2619 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2621 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2622 hold the corresponding uninitialized symbols,
2623 * pic16_allocProcessorRegister: registers have explicit marked the
2625 * pic16_allocInternalRegister: registers are explicit marked as
2627 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2628 processing list, so bit registers were lost,
2631 * ralloc.h: added field 'accessBank' and original symbol operand
2632 in register definition,
2633 * removed the field isMapped from register definition,
2635 ** Several functions have been removed from various sources:
2636 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2637 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2638 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2639 pic16_assignRelocatableRegisters
2641 ** others have been introduced:
2642 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2643 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2645 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2647 * support/scripts/inc2h.pl: changed definition of BIT_AT
2648 to emit 'sbit at' instead of 'bit at'. This was a request.
2650 PIC16 port related preliminary changes:
2651 * gen.c: prefixed function popRegFromString with
2652 pic16_ and all references to it corrected
2653 * pcode.c: all pic16_pc_* hardware registers prefixed
2654 with underscore (_),
2655 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2656 * ralloc.c: newReg(): when register is REG_SFR then
2657 set address to rIdx,
2658 pic16_allocProcessorRegister(): marks register wasUsed=0
2659 pic16_writeUsedRegs(): added a call to assign processor
2660 registers via pic16_assignFixedRegisters
2662 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2664 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2665 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2666 variables in unused register banks. Also the SSEG is placed
2667 wherever there is enough space for it, and IDATA can be anywhere
2668 in internal RAM. For now compile using -Wl-Y[stack_size].
2669 The mem file is different for this option as well, since it
2670 makes no sense of talking about DSEG lenght.
2672 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2674 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2675 in certain cases, e.g. when ROM assignment, patch provided
2676 from Albert den Haan.
2678 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3701 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3702 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

3721 A few small changes that speed up the peephole optimizer.
3725 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3727 Try to make the peephole optimizer smarter by maintaining
3728 an association between the assembly source code and the
3729 iCodes that originated them. Put this information to use
3730 with a new peephole rule condition "notVolatile" so that
3731 the rules can be aggressive yet still safe.
3736 * src/mcs51/peeph.def
3738 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3742 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3743 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3744 if the left or right operand symbols have the accuse flag set.
3746 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3748 Changed the type of the result of the ! (NOT) operator to char;
3749 previously it returned the same type as the source. This allows
3750 us to eliminate all the genFloatNot functions (all of its target
3751 implementations were very buggy) since !float can use the same

3763 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3764 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3765 during interrupts. Ensure WSAVE is located at a shared bank address.
3766 2. Fixed page selection in some places
3767 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3768 the registers name strings.
3769 4. Fixed "signed / unsigned compare" compiler warnings.
3770 5. The PIC port manages its own allocation of the general purpose
3771 registers, but makes no attempt to reuse them. As a result when
3772 compiling it soon runs out of general purpose registers. Some
3773 additional code was added to the files pcode.c and device.c to walk
3774 through the function call tree and rename the registers so that they
3784 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3791 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3793 Made bitfield a distinct type from bit so that bitfields
3794 convert as per ANSI C and bits retain their traditional
3795 boolean style behaviour. Implemented bitfield support in
3803 * src/ds390/gen.c: bit v bitfield split
3804 * src/z80/gen.c: New support for bitfields
3805 * support/regression/tests/bitfields.c: reenabled z80,
3808 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3811 access to xdata mapped I/O devices.
3813 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3815 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3817 Cleaned up genPackBits and genUnpackBits and added two helper
3818 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3819 for literal assignments in genPackBits (thanks to Frieder for
3825 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3827 Fixed bug #748310 (pointer to function type mishandled when the
3828 function name is omitted). Also fixed a SIGSEGV when a function
3829 attribute (reentrant, etc) is used on a non-function or on a
3830 function but misplaced before the parameter list.
3832 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3834 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3857 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3859 Made the constant following the "interrupt" keyword optional. If
3860 omitted, the function will not automatically be given an entry
3861 in the interrupt vector table (similar to #pragma NOIV, but
3862 less syntacticly kludgy). The interrupt number is also now
3863 range checked. Also fixed a bug in the high order bit example

3884 unsigned, but are signed by default
3885 * src/SDCCval.c (constVal): rearranged
3886 * src/SDCCval.c (valMod): preliminary fix
3887 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4378 * doc/sdccman.lyx: fixed bug 739745
4379 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
4381 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4383 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4384 it can be defined with CFLAGS when running configure
4385 * src/SDCCmain.c: fixed compiling + linking with object files
4387 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4389 * configure.in: configure for pic16 port,
4390 added --disable-pic16-port
4391 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4392 * src/SDCCmain.c: linkOptions is changed to set *,
4393 added if/endif conditional macros to remove options help
4394 messages from optionsTable when a port is not configured, added
4395 support for the PIc16 port in the ports table, when executing
4396 the compiler with no port specified on command line, a default
4397 port is selected with the new macro DEFAULT_PORT which is
4398 defined in port.h, in setDefaultOptions() linkOptions is removed
4399 from initialization assignment, since now it is a set,
4400 parseCmdLine uses setParseWithComma for linkOptions, in
4401 linkEdit() linkOptions are accessed with new function indexSet()
4402 which returns the i'th item of a set variable. See SDCCset.c, in
4403 linkEdit() when calling buildCmdLine(), added linkOptions as
4404 last argument. Now users can pass arguments to gplink via the
4405 -Wl option, main() uses pic16glue() to glue up pic16 programs
4406 * src/SDCCpeeph.c: various changes to support pic16
4407 * src/SDCCset.c: added function void *indexSet(set *, int) to

4417 * src/pic16/glue.c: commented out some error producing lines
4418 * src/pic16/main.c: __config directives are commented out to stop
4419 gpasm complaining and test the linkage with gplink, _linkCmd and
4420 _asmCmd changed to be more gplink and gpasm friendly
4421 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4422 produced an error when parsed, peep rule 12 is added to utilize
4423 movff, but it is commented out since the pCode does not support
4424 yet a command with 2 address arguments
4426 2003-05-18 <johan AT balder>
4428 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4455 2003-05-11 Borut Razem <borut.razem AT siol.net>
4457 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4458 the path of bin directory, so that PATH is the only env. variable, which has to be set
4459 in case of standard installation.

5463 * src/SDCCicode.c: fixed array add
5465 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5466 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5467 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5469 2003-01-04 <johan AT balder>
5471 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5473 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5474 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5476 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

5483 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
5484 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5486 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5487 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5489 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5491 * in \sdcc\as\mcs51\ changed these files in order to create an
5492 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5493 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5494 following files to include the previous two files: aslink.dsp,
5495 Makefile.aslink, Makefile.bcc, and Makefile.in.
5497 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5498 .adb instead of .cdb
5500 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5502 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5503 value from option --iram-size.
5505 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5507 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5510 2002-09-18 <wiml AT hhhh.org>
5512 * SDCClrange.h: exposed setFromRange() and setToRange()
5513 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5514 packRegsForAccUse() (bug 542397)
5515 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5516 multiple times and emitting the fetch operations more than once
5517 added aopGetUsesAcc() function to allow binary operators to
5518 fetch their operands in the correct order; made genMinus() emit
5519 compact code for X = LITERAL - Y
5521 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5522 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5523 sprintf() in line 1267.
5525 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5526 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5529 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5530 Changes to aslink (All the changes are marked with 'JCF'):
5532 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5535 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5536 area BSEG. Also moves, if possible, the DATA area down into the internal
5537 ram so more space is available.
5539 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5542 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5543 not bytes. Function summary() which creates a memory usage summary
5544 file with extension .mem. Reports of overlaping stack and small stack
5545 size. If the space for the stack is less than 16 bytes aslink trows a
5548 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5549 the 8051. Option 'y' for memory summary output file.
5551 Changes to sdcc (All the changes are marked with 'JCF'):
5553 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5555 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5556 overlaying area for it (uses RegBankUsed[4]).
5558 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5559 bank zero as used by default. By default aslink locates the stack
5560 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5561 the creation of the .mem file. Delegates the allocation of data area
5562 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5563 the begining of the stack area to aslink.
5565 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5566 glue() in SDCCglue.c creates an area for it.
5568 2002-09-03 Borut Razem <borut.razem AT siol.net>
5569 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5570 sdcc/src/pic/glue.c:
5571 introduced atexit() handler for teporay files removal in case of
5572 errors, assertions, ...
5574 2002-08-29 Borut Razem <borut.razem AT siol.net>
5575 * sdcc/support/cpp2/auto-host_vc_in.h:
5576 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5577 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5578 Maybe there is a similar problem with BORLANDC? It should be checked!
5580 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5581 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5582 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5583 was not executed, and the compiler (cl) launched a warning:
5584 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5586 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5587 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5589 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5590 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5592 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5593 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5594 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5595 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5596 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5597 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5598 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5599 - added Release configuration in VS projects
5600 - review of compiler an linker options
5601 - VC .exe files are generated in bin_vc directory, not to interfere
5602 with binaries generated from other projects (cygwin, mingw, bcc ...)
5604 * sdcc/src/yacc.dsp: added
5606 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5607 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5608 and insert the version number definitions from .version
5610 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5612 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5613 added - genarate auto-host.h using auto-host_vc_in.h as template
5616 removed from CVS, generated automatically
5618 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5619 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5621 2002-08-11 Borut Razem <borut.razem AT siol.net>
5622 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5624 2002-08-10 Borut Razem <borut.razem AT siol.net>
5625 * src/SDCCmain.c (main):
5626 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5627 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5628 The consequence was that some temporary files were not removed.
5631 unification of code in functions tempfilename() and tempfile():
5632 function tempnam() is defined in Visual Studio 6.0 and .NET
5634 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5636 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5637 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5638 - removed compiler command line option /WX: Treats all warnings as errors
5639 - update a list of source files, included into the project
5641 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5642 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5643 changed project type to Generic Project so that can be correcly converted to VS.NET project
5645 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5647 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5649 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5651 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5652 added return 0 statements after assert() to make compiler happy
5654 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5655 added newline in the def file to keep MSC compiler satisfied
5657 * sdcc/src/z80/gen.c:
5658 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5659 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5660 - solved MSC error in function aopDump()
5662 * sdcc_vc.h: define PREFIX as "\\sdcc"
5664 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5665 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5667 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5668 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5669 - Rewrote the register banking algorithm.
5670 - Added pCode live-range analysis to registers (for now, only non-used and
5671 singly-used registers optimized away)
5673 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
