2256 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2258 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2259 loaded with the linker search paths (-L arguments) and the libraries
2260 to be linked with the current source (-l arguments). Changes
2261 currently will affect only the pic16 port.
2262 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2263 include path the port specific paths and port specific libraries,
2264 * gplink command now contains the $3 argument,
2265 * src/pic16/device.h,
2266 * src/pic16/device.c,: structure PIC_device is made public and
2267 renamed to PIC16_device, the same for variable Pics which is renamed

2282 Documenting changes from previous commits.
2283 * configure.in (version 1.56),
2284 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2285 when generating output files to configure the pic16 library,
2286 but now I've commented it out, since gputils aren't installed in the
2287 SF compile farm, so library won't compile
2289 * device/lib/Makefile.in (version 1.56): initially I've added in
2290 target 'all' the prerequestive 'model-pic16' so it compiled the
2291 pic16 library, but now I've commented it out for the same reasons
2293 * added targets 'model-pic16' and 'objects-pic16' to compile the
2295 * added target 'port-specific-objects-pic16' to handle the
2296 generated libraries and copy them into the build/ directory
2297 * added target 'clean-intermediate-pic16' to clean intermediate
2298 files into pic16 directory

2353 data are now emitted in sorted order to reduce section naming,
2354 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2355 weren't marked as being in the access bank,
2357 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2359 Added portion of GNU PIC Library under the directory
2360 device/include/pic16 and device/lib/pic16. These files
2361 contain the declarations of SFRs for the PIC18Fxx2 devices.

2392 all over. Telling LaTeX to be less strict with word spacing
2393 to better keep the right margin. Changed some notes about
2394 maintainance of the ports in section 3.2.1 - is it OK like this?
2396 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2436 * src/pic16/peeph.def: all peepholes with movff are commented out,
2437 because there is a problem in the pcode peep optimizer,
2438 * src/pic16/ralloc.c: the register allocator can now reuse local

2531 include information about variables allocated to the overlay
2534 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2536 * as/mcs51/lkmain.c: Help about -Y option

2546 LEFT_OP (left shift)
2548 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2550 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2551 (default behaviour).
2553 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2555 A python script to validate compiler diagnostic messages. It can be
2556 used to verify that sdcc complains about bad c source code and
2557 gives a good location of the error.
2558 * support/valdiag/Makefile,
2559 * support/valdiag/valdiag.py,
2560 * support/valdiag/tests/*
2562 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2575 * src/common.h: added ifndef/define/endif macros
2576 around the header file.
2577 Bug reported from Jesus Calvino-Fraga
2579 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2581 * sdcc.spec: updated
2582 * device/include/Makefile.in: don't install CVS directories
2583 * device/lib/Makefile.in: added removal of CVS directories after install
2584 * doc/Makefile: fixed install, added local_icons
2585 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2586 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2587 * src/ds390/gen.c (genRightShift): fixed bug #870788
2588 * src/SDCCast.c (decorateType): fixed bug #870781
2590 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2592 PIC16 port related changes:
2593 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2594 added variable stackPos,
2596 * gen.c: genCall, assignResultValue: added support for
2597 pushing/retrieving function parameters to/from stack,
2598 genFunction,genEndFunction: setup stack frame for the
2600 genAddrOf: will be changed according to bug 863624
2602 * added files genutils.c and genutils.h which contain gen*
2603 debugged and optimised functions extracted from gen.c
2605 * glue.c: added variable 'externs' which holds extern symbols,
2606 pic16emitRegularMap: is modified to properly handle relocatable
2607 symbols under the new scheme,
2608 pic16createInterruptVect: is modified
2609 pic16printPublics: is modified to emit 'global' assembler directives,
2610 added pic16_printExterns to print extern symbols,
2611 pic16glue: initializes stack/frame pointer in the beginning of
2612 the assembly output. Temporary hack, will be corrected later,
2613 because gplink yet does not support stack and SDCC does not
2614 yet support a type of crt0.o object to create the final binary.
2616 * Removed many lines that contain 8051 legacy code.
2617 * The code is finally placed under a 'code' directive.
2618 * Added port specific options.
2620 * _process_pragma: simplified since now we do not need *special*
2621 include file to define SFR registers. But a separate header
2622 will be needed. This will be developed later.
2623 * _pic16_parseOptions: added, parses port specific options:
2624 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2625 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2626 --preplace-udata-with=
2628 * _pic16_setDefaultOptions: modified to initialize section names,
2629 but hack is temporarly out of order since it needs improvement.
2630 * _pic16_genAssemblerPreamble: configuration words are emitted by
2631 their address instead of their name. This part is incomplete and
2632 supports only the 18Fxx2 devices. Other devices will emit an error
2633 during assembly since they do not contain the same set of config
2635 * _pic16_genIVT: is modified,
2637 * pcode.c: added definitions for some hardware registers that are needed
2639 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2640 All PCI entries are updated. Now LFSR is supported.
2641 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2642 * added pic16_newpCodeOpLit2 to support instructions with
2643 two literal arguments
2644 * pic16_pCode2str: corrected code that emits assembler instructions
2645 with two literal operands and those that have an access bit modifier
2646 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2647 this fixes a bug which caused some labels to be lost, when an
2648 assembler directive was added, i.e. banksel,
2649 * pic16_FixRegisterBanking: improved logic that causes the insertion
2651 * InlineFunction: functions that are called once, are not any more
2652 inlined. This can be a port option in the future,
2654 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2656 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2657 hold the corresponding uninitialized symbols,
2658 * pic16_allocProcessorRegister: registers have explicit marked the
2660 * pic16_allocInternalRegister: registers are explicit marked as
2662 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2663 processing list, so bit registers were lost,
2666 * ralloc.h: added field 'accessBank' and original symbol operand
2667 in register definition,
2668 * removed the field isMapped from register definition,
2670 ** Several functions have been removed from various sources:
2671 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2672 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2673 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2674 pic16_assignRelocatableRegisters
2676 ** others have been introduced:
2677 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2678 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2680 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2682 * support/scripts/inc2h.pl: changed definition of BIT_AT
2683 to emit 'sbit at' instead of 'bit at'. This was a request.
2685 PIC16 port related preliminary changes:
2686 * gen.c: prefixed function popRegFromString with
2687 pic16_ and all references to it corrected
2688 * pcode.c: all pic16_pc_* hardware registers prefixed
2689 with underscore (_),
2690 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2691 * ralloc.c: newReg(): when register is REG_SFR then
2692 set address to rIdx,
2693 pic16_allocProcessorRegister(): marks register wasUsed=0
2694 pic16_writeUsedRegs(): added a call to assign processor
2695 registers via pic16_assignFixedRegisters
2697 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2699 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2700 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2701 variables in unused register banks. Also the SSEG is placed
2702 wherever there is enough space for it, and IDATA can be anywhere
2703 in internal RAM. For now compile using -Wl-Y[stack_size].
2704 The mem file is different for this option as well, since it
2705 makes no sense of talking about DSEG lenght.
2707 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2709 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2710 in certain cases, e.g. when ROM assignment, patch provided
2711 from Albert den Haan.
2713 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3736 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3737 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

3756 A few small changes that speed up the peephole optimizer.
3760 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3762 Try to make the peephole optimizer smarter by maintaining
3763 an association between the assembly source code and the
3764 iCodes that originated them. Put this information to use
3765 with a new peephole rule condition "notVolatile" so that
3766 the rules can be aggressive yet still safe.
3771 * src/mcs51/peeph.def
3773 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3777 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

3781 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3783 Changed the type of the result of the ! (NOT) operator to char;
3784 previously it returned the same type as the source. This allows
3785 us to eliminate all the genFloatNot functions (all of its target
3786 implementations were very buggy) since !float can use the same
3789 * src/SDCCicode.c (ast2iCode): ! returns char

3798 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3799 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3800 during interrupts. Ensure WSAVE is located at a shared bank address.
3801 2. Fixed page selection in some places
3802 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3803 the registers name strings.
3804 4. Fixed "signed / unsigned compare" compiler warnings.
3805 5. The PIC port manages its own allocation of the general purpose
3806 registers, but makes no attempt to reuse them. As a result when
3807 compiling it soon runs out of general purpose registers. Some
3808 additional code was added to the files pcode.c and device.c to walk
3809 through the function call tree and rename the registers so that they
3819 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3820 genPlus() & genMinus() when the result is the same as left or right

3826 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3828 Made bitfield a distinct type from bit so that bitfields
3829 convert as per ANSI C and bits retain their traditional
3830 boolean style behaviour. Implemented bitfield support in
3838 * src/ds390/gen.c: bit v bitfield split
3839 * src/z80/gen.c: New support for bitfields
3840 * support/regression/tests/bitfields.c: reenabled z80,
3843 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3845 Rules 246.x, 247.x relate to bitfields, the others speed up
3846 access to xdata mapped I/O devices.
3848 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3850 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3852 Cleaned up genPackBits and genUnpackBits and added two helper
3853 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3854 for literal assignments in genPackBits (thanks to Frieder for
3860 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3862 Fixed bug #748310 (pointer to function type mishandled when the
3863 function name is omitted). Also fixed a SIGSEGV when a function
3864 attribute (reentrant, etc) is used on a non-function or on a
3865 function but misplaced before the parameter list.

3892 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3894 Made the constant following the "interrupt" keyword optional. If
3895 omitted, the function will not automatically be given an entry
3896 in the interrupt vector table (similar to #pragma NOIV, but
3897 less syntacticly kludgy). The interrupt number is also now
3898 range checked. Also fixed a bug in the high order bit example

4394 Applied patch from bug 737905 (renamed yylineo to mylineno):
4401 * src/pic16/pcode.c: Cleaned warnings
4402 * src/pic16/pcodeflow.c: Cleaned warnings
4403 * src/pic16/pcoderegs.c: Cleaned warnings
4405 2003-05-19 Scott Dattalo <scott AT dattalo.com>

4416 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4418 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4419 it can be defined with CFLAGS when running configure
4420 * src/SDCCmain.c: fixed compiling + linking with object files
4422 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4424 * configure.in: configure for pic16 port,
4425 added --disable-pic16-port
4426 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4427 * src/SDCCmain.c: linkOptions is changed to set *,
4428 added if/endif conditional macros to remove options help
4429 messages from optionsTable when a port is not configured, added
4430 support for the PIc16 port in the ports table, when executing
4431 the compiler with no port specified on command line, a default
4432 port is selected with the new macro DEFAULT_PORT which is
4433 defined in port.h, in setDefaultOptions() linkOptions is removed
4434 from initialization assignment, since now it is a set,
4435 parseCmdLine uses setParseWithComma for linkOptions, in
4436 linkEdit() linkOptions are accessed with new function indexSet()
4437 which returns the i'th item of a set variable. See SDCCset.c, in
4438 linkEdit() when calling buildCmdLine(), added linkOptions as
4439 last argument. Now users can pass arguments to gplink via the
4440 -Wl option, main() uses pic16glue() to glue up pic16 programs

4452 * src/pic16/glue.c: commented out some error producing lines
4453 * src/pic16/main.c: __config directives are commented out to stop
4454 gpasm complaining and test the linkage with gplink, _linkCmd and
4455 _asmCmd changed to be more gplink and gpasm friendly
4456 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4457 produced an error when parsed, peep rule 12 is added to utilize
4458 movff, but it is commented out since the pCode does not support
4459 yet a command with 2 address arguments
4461 2003-05-18 <johan AT balder>
4463 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4490 2003-05-11 Borut Razem <borut.razem AT siol.net>
4492 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4493 the path of bin directory, so that PATH is the only env. variable, which has to be set

5502 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
5504 2003-01-04 <johan AT balder>
5506 * src/SDCCval.c (getNelements): fixed the initialized array of structures
5508 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5509 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

5521 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5522 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5524 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5526 * in \sdcc\as\mcs51\ changed these files in order to create an
5527 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5528 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5529 following files to include the previous two files: aslink.dsp,
5530 Makefile.aslink, Makefile.bcc, and Makefile.in.
5532 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5533 .adb instead of .cdb
5535 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5537 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5538 value from option --iram-size.
5540 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5542 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5545 2002-09-18 <wiml AT hhhh.org>
5547 * SDCClrange.h: exposed setFromRange() and setToRange()
5548 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5549 packRegsForAccUse() (bug 542397)
5550 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5551 multiple times and emitting the fetch operations more than once
5552 added aopGetUsesAcc() function to allow binary operators to
5553 fetch their operands in the correct order; made genMinus() emit
5554 compact code for X = LITERAL - Y
5556 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5557 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5558 sprintf() in line 1267.
5560 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5561 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5564 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5565 Changes to aslink (All the changes are marked with 'JCF'):
5567 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5570 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5571 area BSEG. Also moves, if possible, the DATA area down into the internal
5572 ram so more space is available.
5574 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5577 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5578 not bytes. Function summary() which creates a memory usage summary
5579 file with extension .mem. Reports of overlaping stack and small stack
5580 size. If the space for the stack is less than 16 bytes aslink trows a
5583 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5584 the 8051. Option 'y' for memory summary output file.
5586 Changes to sdcc (All the changes are marked with 'JCF'):
5588 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5590 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5591 overlaying area for it (uses RegBankUsed[4]).
5593 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5594 bank zero as used by default. By default aslink locates the stack
5595 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5596 the creation of the .mem file. Delegates the allocation of data area
5597 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5598 the begining of the stack area to aslink.
5600 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5601 glue() in SDCCglue.c creates an area for it.
5603 2002-09-03 Borut Razem <borut.razem AT siol.net>
5604 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5605 sdcc/src/pic/glue.c:
5606 introduced atexit() handler for teporay files removal in case of
5607 errors, assertions, ...
5609 2002-08-29 Borut Razem <borut.razem AT siol.net>
5610 * sdcc/support/cpp2/auto-host_vc_in.h:
5611 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5612 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5613 Maybe there is a similar problem with BORLANDC? It should be checked!
5615 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5616 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5617 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5618 was not executed, and the compiler (cl) launched a warning:
5619 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5621 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5622 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5624 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5625 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
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,

5632 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5633 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5634 - added Release configuration in VS projects
5635 - review of compiler an linker options
5636 - VC .exe files are generated in bin_vc directory, not to interfere
5637 with binaries generated from other projects (cygwin, mingw, bcc ...)
5639 * sdcc/src/yacc.dsp: added
5641 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5642 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5643 and insert the version number definitions from .version
5645 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5647 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5648 added - genarate auto-host.h using auto-host_vc_in.h as template
5651 removed from CVS, generated automatically
5653 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5654 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5656 2002-08-11 Borut Razem <borut.razem AT siol.net>
5657 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5659 2002-08-10 Borut Razem <borut.razem AT siol.net>
5660 * src/SDCCmain.c (main):
5661 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5662 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5663 The consequence was that some temporary files were not removed.
5666 unification of code in functions tempfilename() and tempfile():
5667 function tempnam() is defined in Visual Studio 6.0 and .NET
5669 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5671 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5672 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5673 - removed compiler command line option /WX: Treats all warnings as errors
5674 - update a list of source files, included into the project
5676 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5677 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5678 changed project type to Generic Project so that can be correcly converted to VS.NET project
5680 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5682 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5684 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

5874 * sdcc/src/SDCCloop.c:
5875 Previous fix was not good. basic blocks that have "break" or "return" are
5876 not really partof a loop , but live ranges used in these blocks should
5877 be live thru the entire loop, so set partOfLoop but don't add them to
