2212 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2214 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2215 loaded with the linker search paths (-L arguments) and the libraries
2216 to be linked with the current source (-l arguments). Changes
2217 currently will affect only the pic16 port.
2218 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2219 include path the port specific paths and port specific libraries,
2220 * gplink command now contains the $3 argument,
2221 * src/pic16/device.h,
2222 * src/pic16/device.c,: structure PIC_device is made public and
2223 renamed to PIC16_device, the same for variable Pics which is renamed

2238 Documenting changes from previous commits.
2239 * configure.in (version 1.56),
2240 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2241 when generating output files to configure the pic16 library,
2242 but now I've commented it out, since gputils aren't installed in the
2243 SF compile farm, so library won't compile
2245 * device/lib/Makefile.in (version 1.56): initially I've added in
2246 target 'all' the prerequestive 'model-pic16' so it compiled the
2247 pic16 library, but now I've commented it out for the same reasons
2249 * added targets 'model-pic16' and 'objects-pic16' to compile the
2251 * added target 'port-specific-objects-pic16' to handle the
2252 generated libraries and copy them into the build/ directory
2253 * added target 'clean-intermediate-pic16' to clean intermediate
2254 files into pic16 directory
2255 * in target 'installdirs' added line to create directory pic16 in
2256 the installation path
2258 * device/include/Makefile.in (version 1.11): in target 'install'
2259 added lines to copy all header files to installation path,
2260 * in target 'installdirs' added line create directory for pic16
2261 headers in the installation path

2276 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2277 option so that it actually works. Made it specific to the z80, since
2278 the gbz80 doesn't have these kinds of I/O ports.
2280 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2282 * device/include/z180.h,

2306 via literal number. The symbol is placed in the corresponding
2307 position of the data ram
2308 * (pic16_dump_section): relocatable and absolute uninitialized
2309 data are now emitted in sorted order to reduce section naming,
2310 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2311 weren't marked as being in the access bank,
2313 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

2348 all over. Telling LaTeX to be less strict with word spacing
2349 to better keep the right margin. Changed some notes about
2350 maintainance of the ports in section 3.2.1 - is it OK like this?
2352 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2392 * src/pic16/peeph.def: all peepholes with movff are commented out,
2393 because there is a problem in the pcode peep optimizer,
2394 * src/pic16/ralloc.c: the register allocator can now reuse local

2487 include information about variables allocated to the overlay
2490 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2492 * as/mcs51/lkmain.c: Help about -Y option

2504 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2506 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2507 (default behaviour).
2509 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2511 A python script to validate compiler diagnostic messages. It can be
2512 used to verify that sdcc complains about bad c source code and
2513 gives a good location of the error.
2514 * support/valdiag/Makefile,
2515 * support/valdiag/valdiag.py,
2516 * support/valdiag/tests/*
2518 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2532 around the header file.
2533 Bug reported from Jesus Calvino-Fraga
2535 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2537 * sdcc.spec: updated
2538 * device/include/Makefile.in: don't install CVS directories
2539 * device/lib/Makefile.in: added removal of CVS directories after install
2540 * doc/Makefile: fixed install, added local_icons
2541 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2542 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2543 * src/ds390/gen.c (genRightShift): fixed bug #870788
2544 * src/SDCCast.c (decorateType): fixed bug #870781
2546 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2548 PIC16 port related changes:
2549 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2550 added variable stackPos,
2552 * gen.c: genCall, assignResultValue: added support for
2553 pushing/retrieving function parameters to/from stack,
2554 genFunction,genEndFunction: setup stack frame for the
2556 genAddrOf: will be changed according to bug 863624
2558 * added files genutils.c and genutils.h which contain gen*
2559 debugged and optimised functions extracted from gen.c
2561 * glue.c: added variable 'externs' which holds extern symbols,
2562 pic16emitRegularMap: is modified to properly handle relocatable
2563 symbols under the new scheme,
2564 pic16createInterruptVect: is modified
2565 pic16printPublics: is modified to emit 'global' assembler directives,
2566 added pic16_printExterns to print extern symbols,
2567 pic16glue: initializes stack/frame pointer in the beginning of
2568 the assembly output. Temporary hack, will be corrected later,
2569 because gplink yet does not support stack and SDCC does not
2570 yet support a type of crt0.o object to create the final binary.
2572 * Removed many lines that contain 8051 legacy code.
2573 * The code is finally placed under a 'code' directive.
2574 * Added port specific options.
2576 * _process_pragma: simplified since now we do not need *special*
2577 include file to define SFR registers. But a separate header
2578 will be needed. This will be developed later.
2579 * _pic16_parseOptions: added, parses port specific options:
2580 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2581 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2582 --preplace-udata-with=
2584 * _pic16_setDefaultOptions: modified to initialize section names,
2585 but hack is temporarly out of order since it needs improvement.
2586 * _pic16_genAssemblerPreamble: configuration words are emitted by
2587 their address instead of their name. This part is incomplete and
2588 supports only the 18Fxx2 devices. Other devices will emit an error
2589 during assembly since they do not contain the same set of config
2591 * _pic16_genIVT: is modified,
2593 * pcode.c: added definitions for some hardware registers that are needed
2595 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2596 All PCI entries are updated. Now LFSR is supported.
2597 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2598 * added pic16_newpCodeOpLit2 to support instructions with
2599 two literal arguments
2600 * pic16_pCode2str: corrected code that emits assembler instructions
2601 with two literal operands and those that have an access bit modifier
2602 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2603 this fixes a bug which caused some labels to be lost, when an
2604 assembler directive was added, i.e. banksel,
2605 * pic16_FixRegisterBanking: improved logic that causes the insertion
2607 * InlineFunction: functions that are called once, are not any more
2608 inlined. This can be a port option in the future,
2610 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2612 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2613 hold the corresponding uninitialized symbols,
2614 * pic16_allocProcessorRegister: registers have explicit marked the
2616 * pic16_allocInternalRegister: registers are explicit marked as
2618 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2619 processing list, so bit registers were lost,
2622 * ralloc.h: added field 'accessBank' and original symbol operand
2623 in register definition,
2624 * removed the field isMapped from register definition,
2626 ** Several functions have been removed from various sources:
2627 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2628 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2629 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2630 pic16_assignRelocatableRegisters
2632 ** others have been introduced:
2633 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2634 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2636 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2638 * support/scripts/inc2h.pl: changed definition of BIT_AT
2639 to emit 'sbit at' instead of 'bit at'. This was a request.
2641 PIC16 port related preliminary changes:
2642 * gen.c: prefixed function popRegFromString with
2643 pic16_ and all references to it corrected
2644 * pcode.c: all pic16_pc_* hardware registers prefixed
2645 with underscore (_),
2646 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2647 * ralloc.c: newReg(): when register is REG_SFR then
2648 set address to rIdx,
2649 pic16_allocProcessorRegister(): marks register wasUsed=0
2650 pic16_writeUsedRegs(): added a call to assign processor
2651 registers via pic16_assignFixedRegisters
2653 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2655 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2656 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2657 variables in unused register banks. Also the SSEG is placed
2658 wherever there is enough space for it, and IDATA can be anywhere
2659 in internal RAM. For now compile using -Wl-Y[stack_size].
2660 The mem file is different for this option as well, since it
2661 makes no sense of talking about DSEG lenght.
2663 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2665 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2666 in certain cases, e.g. when ROM assignment, patch provided
2667 from Albert den Haan.
2669 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3692 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3693 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3694 type for bits was changed. It resulted in bit variables becoming
3695 global, which is not permitted in PIC 14 assembly output.

3712 A few small changes that speed up the peephole optimizer.
3716 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3718 Try to make the peephole optimizer smarter by maintaining
3719 an association between the assembly source code and the
3720 iCodes that originated them. Put this information to use
3721 with a new peephole rule condition "notVolatile" so that
3722 the rules can be aggressive yet still safe.
3727 * src/mcs51/peeph.def
3729 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3733 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3734 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3735 if the left or right operand symbols have the accuse flag set.
3737 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3739 Changed the type of the result of the ! (NOT) operator to char;
3740 previously it returned the same type as the source. This allows
3741 us to eliminate all the genFloatNot functions (all of its target
3742 implementations were very buggy) since !float can use the same

3754 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3755 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3756 during interrupts. Ensure WSAVE is located at a shared bank address.
3757 2. Fixed page selection in some places
3758 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3759 the registers name strings.
3760 4. Fixed "signed / unsigned compare" compiler warnings.
3761 5. The PIC port manages its own allocation of the general purpose
3762 registers, but makes no attempt to reuse them. As a result when
3763 compiling it soon runs out of general purpose registers. Some
3764 additional code was added to the files pcode.c and device.c to walk
3765 through the function call tree and rename the registers so that they
3775 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3776 genPlus() & genMinus() when the result is the same as left or right

3782 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3784 Made bitfield a distinct type from bit so that bitfields
3785 convert as per ANSI C and bits retain their traditional
3786 boolean style behaviour. Implemented bitfield support in

3802 access to xdata mapped I/O devices.
3804 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3806 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3808 Cleaned up genPackBits and genUnpackBits and added two helper
3809 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3810 for literal assignments in genPackBits (thanks to Frieder for
3816 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3818 Fixed bug #748310 (pointer to function type mishandled when the
3819 function name is omitted). Also fixed a SIGSEGV when a function
3820 attribute (reentrant, etc) is used on a non-function or on a
3821 function but misplaced before the parameter list.

3850 Made the constant following the "interrupt" keyword optional. If
3851 omitted, the function will not automatically be given an entry
3852 in the interrupt vector table (similar to #pragma NOIV, but
3853 less syntacticly kludgy). The interrupt number is also now
3854 range checked. Also fixed a bug in the high order bit example

3875 unsigned, but are signed by default
3876 * src/SDCCval.c (constVal): rearranged
3877 * src/SDCCval.c (valMod): preliminary fix
3878 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4369 * doc/sdccman.lyx: fixed bug 739745
4370 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
4372 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4374 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4375 it can be defined with CFLAGS when running configure
4376 * src/SDCCmain.c: fixed compiling + linking with object files
4378 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4380 * configure.in: configure for pic16 port,
4381 added --disable-pic16-port
4382 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4383 * src/SDCCmain.c: linkOptions is changed to set *,
4384 added if/endif conditional macros to remove options help
4385 messages from optionsTable when a port is not configured, added
4386 support for the PIc16 port in the ports table, when executing
4387 the compiler with no port specified on command line, a default
4388 port is selected with the new macro DEFAULT_PORT which is
4389 defined in port.h, in setDefaultOptions() linkOptions is removed
4390 from initialization assignment, since now it is a set,
4391 parseCmdLine uses setParseWithComma for linkOptions, in
4392 linkEdit() linkOptions are accessed with new function indexSet()
4393 which returns the i'th item of a set variable. See SDCCset.c, in
4394 linkEdit() when calling buildCmdLine(), added linkOptions as
4395 last argument. Now users can pass arguments to gplink via the
4396 -Wl option, main() uses pic16glue() to glue up pic16 programs
4397 * src/SDCCpeeph.c: various changes to support pic16
4398 * src/SDCCset.c: added function void *indexSet(set *, int) to

4408 * src/pic16/glue.c: commented out some error producing lines
4409 * src/pic16/main.c: __config directives are commented out to stop
4410 gpasm complaining and test the linkage with gplink, _linkCmd and
4411 _asmCmd changed to be more gplink and gpasm friendly
4412 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4413 produced an error when parsed, peep rule 12 is added to utilize
4414 movff, but it is commented out since the pCode does not support
4415 yet a command with 2 address arguments
4417 2003-05-18 <johan AT balder>
4419 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4446 2003-05-11 Borut Razem <borut.razem AT siol.net>
4448 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4449 the path of bin directory, so that PATH is the only env. variable, which has to be set
4450 in case of standard installation.

5437 2003-01-07 <johan AT balder>
5439 * src/SDCCast.c (decorateType): fixed bug #600035

5454 * src/SDCCicode.c: fixed array add
5456 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
5457 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
5458 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5460 2003-01-04 <johan AT balder>
5462 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5464 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5465 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5467 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5468 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

5474 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
5475 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5477 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5478 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5480 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5482 * in \sdcc\as\mcs51\ changed these files in order to create an
5483 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5484 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5485 following files to include the previous two files: aslink.dsp,
5486 Makefile.aslink, Makefile.bcc, and Makefile.in.
5488 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5489 .adb instead of .cdb
5491 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5493 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5494 value from option --iram-size.
5496 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5498 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5501 2002-09-18 <wiml AT hhhh.org>
5503 * SDCClrange.h: exposed setFromRange() and setToRange()
5504 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5505 packRegsForAccUse() (bug 542397)
5506 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5507 multiple times and emitting the fetch operations more than once
5508 added aopGetUsesAcc() function to allow binary operators to
5509 fetch their operands in the correct order; made genMinus() emit
5510 compact code for X = LITERAL - Y
5512 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5513 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5514 sprintf() in line 1267.
5516 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5517 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5520 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5521 Changes to aslink (All the changes are marked with 'JCF'):
5523 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5526 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5527 area BSEG. Also moves, if possible, the DATA area down into the internal
5528 ram so more space is available.
5530 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5533 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5534 not bytes. Function summary() which creates a memory usage summary
5535 file with extension .mem. Reports of overlaping stack and small stack
5536 size. If the space for the stack is less than 16 bytes aslink trows a
5539 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5540 the 8051. Option 'y' for memory summary output file.
5542 Changes to sdcc (All the changes are marked with 'JCF'):
5544 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5546 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5547 overlaying area for it (uses RegBankUsed[4]).
5549 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5550 bank zero as used by default. By default aslink locates the stack
5551 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5552 the creation of the .mem file. Delegates the allocation of data area
5553 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5554 the begining of the stack area to aslink.
5556 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5557 glue() in SDCCglue.c creates an area for it.
5559 2002-09-03 Borut Razem <borut.razem AT siol.net>
5560 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5561 sdcc/src/pic/glue.c:
5562 introduced atexit() handler for teporay files removal in case of
5563 errors, assertions, ...
5565 2002-08-29 Borut Razem <borut.razem AT siol.net>
5566 * sdcc/support/cpp2/auto-host_vc_in.h:
5567 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5568 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5569 Maybe there is a similar problem with BORLANDC? It should be checked!
5571 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5572 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5573 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5574 was not executed, and the compiler (cl) launched a warning:
5575 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5577 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5578 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5580 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5581 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5583 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5584 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5585 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5586 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5587 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5588 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5589 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5590 - added Release configuration in VS projects
5591 - review of compiler an linker options
5592 - VC .exe files are generated in bin_vc directory, not to interfere
5593 with binaries generated from other projects (cygwin, mingw, bcc ...)
5595 * sdcc/src/yacc.dsp: added
5597 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5598 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5599 and insert the version number definitions from .version
5601 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5603 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5604 added - genarate auto-host.h using auto-host_vc_in.h as template
5607 removed from CVS, generated automatically
5609 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5610 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5612 2002-08-11 Borut Razem <borut.razem AT siol.net>
5613 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5615 2002-08-10 Borut Razem <borut.razem AT siol.net>
5616 * src/SDCCmain.c (main):
5617 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5618 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5619 The consequence was that some temporary files were not removed.
5622 unification of code in functions tempfilename() and tempfile():
5623 function tempnam() is defined in Visual Studio 6.0 and .NET
5625 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5627 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5628 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5629 - removed compiler command line option /WX: Treats all warnings as errors
5630 - update a list of source files, included into the project
5632 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5633 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5634 changed project type to Generic Project so that can be correcly converted to VS.NET project
5636 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5638 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5640 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5642 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5643 added return 0 statements after assert() to make compiler happy
5645 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5646 added newline in the def file to keep MSC compiler satisfied
5648 * sdcc/src/z80/gen.c:
5649 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5650 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5651 - solved MSC error in function aopDump()
5653 * sdcc_vc.h: define PREFIX as "\\sdcc"
5655 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5656 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5658 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5659 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5660 - Rewrote the register banking algorithm.
5661 - Added pCode live-range analysis to registers (for now, only non-used and
5662 singly-used registers optimized away)
5664 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5666 * 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.
5668 2002-05-10 Scott Dattalo <scott AT dattalo.com>
5669 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
5671 2002-04-22 Michael Hope <michaelh AT vroom>
5673 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
