1370 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1372 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1373 loaded with the linker search paths (-L arguments) and the libraries
1374 to be linked with the current source (-l arguments). Changes
1375 currently will affect only the pic16 port.
1376 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1377 include path the port specific paths and port specific libraries,
1378 * gplink command now contains the $3 argument,
1379 * src/pic16/device.h,
1380 * src/pic16/device.c,: structure PIC_device is made public and
1381 renamed to PIC16_device, the same for variable Pics which is renamed

1396 Documenting changes from previous commits.
1397 * configure.in (version 1.56),
1398 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1399 when generating output files to configure the pic16 library,
1400 but now I've commented it out, since gputils aren't installed in the
1401 SF compile farm, so library won't compile
1403 * device/lib/Makefile.in (version 1.56): initially I've added in
1404 target 'all' the prerequestive 'model-pic16' so it compiled the
1405 pic16 library, but now I've commented it out for the same reasons
1407 * added targets 'model-pic16' and 'objects-pic16' to compile the
1409 * added target 'port-specific-objects-pic16' to handle the
1410 generated libraries and copy them into the build/ directory

1464 via literal number. The symbol is placed in the corresponding
1465 position of the data ram
1466 * (pic16_dump_section): relocatable and absolute uninitialized
1467 data are now emitted in sorted order to reduce section naming,
1468 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1469 weren't marked as being in the access bank,
1471 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1473 Added portion of GNU PIC Library under the directory
1474 device/include/pic16 and device/lib/pic16. These files
1475 contain the declarations of SFRs for the PIC18Fxx2 devices.
1476 The directory is initialized via configure from toplevel.
1478 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1480 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

1506 all over. Telling LaTeX to be less strict with word spacing
1507 to better keep the right margin. Changed some notes about
1508 maintainance of the ports in section 3.2.1 - is it OK like this?
1510 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1548 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1550 * src/pic16/peeph.def: all peepholes with movff are commented out,
1551 because there is a problem in the pcode peep optimizer,
1552 * src/pic16/ralloc.c: the register allocator can now reuse local

1645 include information about variables allocated to the overlay
1648 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1650 * as/mcs51/lkmain.c: Help about -Y option

1662 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1664 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1665 (default behaviour).
1667 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1669 A python script to validate compiler diagnostic messages. It can be
1670 used to verify that sdcc complains about bad c source code and
1671 gives a good location of the error.
1672 * support/valdiag/Makefile,
1673 * support/valdiag/valdiag.py,
1674 * support/valdiag/tests/*
1676 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1678 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

1689 * src/common.h: added ifndef/define/endif macros
1690 around the header file.
1691 Bug reported from Jesus Calvino-Fraga
1693 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1695 * sdcc.spec: updated
1696 * device/include/Makefile.in: don't install CVS directories
1697 * device/lib/Makefile.in: added removal of CVS directories after install
1698 * doc/Makefile: fixed install, added local_icons
1699 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1700 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1701 * src/ds390/gen.c (genRightShift): fixed bug #870788
1702 * src/SDCCast.c (decorateType): fixed bug #870781
1704 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1706 PIC16 port related changes:
1707 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1708 added variable stackPos,
1710 * gen.c: genCall, assignResultValue: added support for
1711 pushing/retrieving function parameters to/from stack,
1712 genFunction,genEndFunction: setup stack frame for the
1714 genAddrOf: will be changed according to bug 863624
1716 * added files genutils.c and genutils.h which contain gen*
1717 debugged and optimised functions extracted from gen.c
1719 * glue.c: added variable 'externs' which holds extern symbols,
1720 pic16emitRegularMap: is modified to properly handle relocatable
1721 symbols under the new scheme,
1722 pic16createInterruptVect: is modified
1723 pic16printPublics: is modified to emit 'global' assembler directives,
1724 added pic16_printExterns to print extern symbols,
1725 pic16glue: initializes stack/frame pointer in the beginning of
1726 the assembly output. Temporary hack, will be corrected later,
1727 because gplink yet does not support stack and SDCC does not
1728 yet support a type of crt0.o object to create the final binary.
1730 * Removed many lines that contain 8051 legacy code.
1731 * The code is finally placed under a 'code' directive.
1732 * Added port specific options.
1734 * _process_pragma: simplified since now we do not need *special*
1735 include file to define SFR registers. But a separate header
1736 will be needed. This will be developed later.
1737 * _pic16_parseOptions: added, parses port specific options:
1738 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1739 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1740 --preplace-udata-with=
1742 * _pic16_setDefaultOptions: modified to initialize section names,
1743 but hack is temporarly out of order since it needs improvement.
1744 * _pic16_genAssemblerPreamble: configuration words are emitted by
1745 their address instead of their name. This part is incomplete and
1746 supports only the 18Fxx2 devices. Other devices will emit an error
1747 during assembly since they do not contain the same set of config
1749 * _pic16_genIVT: is modified,
1751 * pcode.c: added definitions for some hardware registers that are needed
1753 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1754 All PCI entries are updated. Now LFSR is supported.
1755 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1756 * added pic16_newpCodeOpLit2 to support instructions with
1757 two literal arguments
1758 * pic16_pCode2str: corrected code that emits assembler instructions
1759 with two literal operands and those that have an access bit modifier
1760 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1761 this fixes a bug which caused some labels to be lost, when an
1762 assembler directive was added, i.e. banksel,
1763 * pic16_FixRegisterBanking: improved logic that causes the insertion
1765 * InlineFunction: functions that are called once, are not any more
1766 inlined. This can be a port option in the future,
1768 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1770 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1771 hold the corresponding uninitialized symbols,
1772 * pic16_allocProcessorRegister: registers have explicit marked the
1774 * pic16_allocInternalRegister: registers are explicit marked as
1776 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1777 processing list, so bit registers were lost,
1780 * ralloc.h: added field 'accessBank' and original symbol operand
1781 in register definition,
1782 * removed the field isMapped from register definition,
1784 ** Several functions have been removed from various sources:
1785 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1786 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1787 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1788 pic16_assignRelocatableRegisters
1790 ** others have been introduced:
1791 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1792 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1794 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1796 * support/scripts/inc2h.pl: changed definition of BIT_AT
1797 to emit 'sbit at' instead of 'bit at'. This was a request.
1799 PIC16 port related preliminary changes:
1800 * gen.c: prefixed function popRegFromString with
1801 pic16_ and all references to it corrected
1802 * pcode.c: all pic16_pc_* hardware registers prefixed
1803 with underscore (_),
1804 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1805 * ralloc.c: newReg(): when register is REG_SFR then
1806 set address to rIdx,
1807 pic16_allocProcessorRegister(): marks register wasUsed=0
1808 pic16_writeUsedRegs(): added a call to assign processor
1809 registers via pic16_assignFixedRegisters
1811 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1813 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1814 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1815 variables in unused register banks. Also the SSEG is placed
1816 wherever there is enough space for it, and IDATA can be anywhere
1817 in internal RAM. For now compile using -Wl-Y[stack_size].
1818 The mem file is different for this option as well, since it
1819 makes no sense of talking about DSEG lenght.
1821 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1823 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1824 in certain cases, e.g. when ROM assignment, patch provided
1825 from Albert den Haan.
1827 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2850 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2851 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

2870 A few small changes that speed up the peephole optimizer.
2874 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2876 Try to make the peephole optimizer smarter by maintaining
2877 an association between the assembly source code and the
2878 iCodes that originated them. Put this information to use
2879 with a new peephole rule condition "notVolatile" so that
2880 the rules can be aggressive yet still safe.
2885 * src/mcs51/peeph.def
2887 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2895 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2897 Changed the type of the result of the ! (NOT) operator to char;
2898 previously it returned the same type as the source. This allows
2899 us to eliminate all the genFloatNot functions (all of its target
2900 implementations were very buggy) since !float can use the same
2903 * src/SDCCicode.c (ast2iCode): ! returns char
2904 * src/mcs51/gen.c (genNot, genNotFloat),
2905 * src/ds390/gen.c (genNot, genNotFloat),
2906 * src/z80/gen.c (genNot, genNotFloat),
2907 * src/pic/gen.c (genNot, genNotFloat),

2910 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
2912 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2913 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2914 during interrupts. Ensure WSAVE is located at a shared bank address.
2915 2. Fixed page selection in some places
2916 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2917 the registers name strings.
2918 4. Fixed "signed / unsigned compare" compiler warnings.
2919 5. The PIC port manages its own allocation of the general purpose
2920 registers, but makes no attempt to reuse them. As a result when
2921 compiling it soon runs out of general purpose registers. Some
2922 additional code was added to the files pcode.c and device.c to walk
2923 through the function call tree and rename the registers so that they
2933 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2934 genPlus() & genMinus() when the result is the same as left or right

2940 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2942 Made bitfield a distinct type from bit so that bitfields
2943 convert as per ANSI C and bits retain their traditional
2944 boolean style behaviour. Implemented bitfield support in
2952 * src/ds390/gen.c: bit v bitfield split
2953 * src/z80/gen.c: New support for bitfields
2954 * support/regression/tests/bitfields.c: reenabled z80,
2957 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2959 Rules 246.x, 247.x relate to bitfields, the others speed up
2960 access to xdata mapped I/O devices.
2962 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2964 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2966 Cleaned up genPackBits and genUnpackBits and added two helper
2967 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2968 for literal assignments in genPackBits (thanks to Frieder for
2974 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2976 Fixed bug #748310 (pointer to function type mishandled when the
2977 function name is omitted). Also fixed a SIGSEGV when a function
2978 attribute (reentrant, etc) is used on a non-function or on a
2979 function but misplaced before the parameter list.

3006 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3008 Made the constant following the "interrupt" keyword optional. If
3009 omitted, the function will not automatically be given an entry
3010 in the interrupt vector table (similar to #pragma NOIV, but
3011 less syntacticly kludgy). The interrupt number is also now
3012 range checked. Also fixed a bug in the high order bit example

3490 * doc/sdccman.lyx: added latex preamble for hyperref package.
3491 Using pdflatex this will give you a hyperlinked pdf file with
3492 bookmarks. (prepend '%' before /usepackage if this breaks something)

3508 Applied patch from bug 737905 (renamed yylineo to mylineno):
3515 * src/pic16/pcode.c: Cleaned warnings
3516 * src/pic16/pcodeflow.c: Cleaned warnings
3517 * src/pic16/pcoderegs.c: Cleaned warnings

3533 it can be defined with CFLAGS when running configure
3534 * src/SDCCmain.c: fixed compiling + linking with object files
3536 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
3538 * configure.in: configure for pic16 port,
3539 added --disable-pic16-port
3540 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3541 * src/SDCCmain.c: linkOptions is changed to set *,
3542 added if/endif conditional macros to remove options help
3543 messages from optionsTable when a port is not configured, added
3544 support for the PIc16 port in the ports table, when executing
3545 the compiler with no port specified on command line, a default
3546 port is selected with the new macro DEFAULT_PORT which is
3547 defined in port.h, in setDefaultOptions() linkOptions is removed
3548 from initialization assignment, since now it is a set,
3549 parseCmdLine uses setParseWithComma for linkOptions, in
3550 linkEdit() linkOptions are accessed with new function indexSet()
3551 which returns the i'th item of a set variable. See SDCCset.c, in
3552 linkEdit() when calling buildCmdLine(), added linkOptions as
3553 last argument. Now users can pass arguments to gplink via the
3554 -Wl option, main() uses pic16glue() to glue up pic16 programs
3555 * src/SDCCpeeph.c: various changes to support pic16

3566 * src/pic16/glue.c: commented out some error producing lines
3567 * src/pic16/main.c: __config directives are commented out to stop
3568 gpasm complaining and test the linkage with gplink, _linkCmd and
3569 _asmCmd changed to be more gplink and gpasm friendly
3570 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3571 produced an error when parsed, peep rule 12 is added to utilize
3572 movff, but it is commented out since the pCode does not support
3573 yet a command with 2 address arguments
3575 2003-05-18 <johan AT balder>
3577 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

3604 2003-05-11 Borut Razem <borut.razem AT siol.net>
3606 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3607 the path of bin directory, so that PATH is the only env. variable, which has to be set
3608 in case of standard installation.

4616 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
4618 2003-01-04 <johan AT balder>
4620 * src/SDCCval.c (getNelements): fixed the initialized array of structures
4622 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

4635 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4636 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4638 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4640 * in \sdcc\as\mcs51\ changed these files in order to create an
4641 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4642 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4643 following files to include the previous two files: aslink.dsp,
4644 Makefile.aslink, Makefile.bcc, and Makefile.in.
4646 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4647 .adb instead of .cdb
4649 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4651 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4652 value from option --iram-size.
4654 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4656 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4659 2002-09-18 <wiml AT hhhh.org>
4661 * SDCClrange.h: exposed setFromRange() and setToRange()
4662 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4663 packRegsForAccUse() (bug 542397)
4664 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4665 multiple times and emitting the fetch operations more than once
4666 added aopGetUsesAcc() function to allow binary operators to
4667 fetch their operands in the correct order; made genMinus() emit
4668 compact code for X = LITERAL - Y
4670 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4671 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4672 sprintf() in line 1267.
4674 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4675 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4678 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4679 Changes to aslink (All the changes are marked with 'JCF'):
4681 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4684 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4685 area BSEG. Also moves, if possible, the DATA area down into the internal
4686 ram so more space is available.
4688 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4691 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4692 not bytes. Function summary() which creates a memory usage summary
4693 file with extension .mem. Reports of overlaping stack and small stack
4694 size. If the space for the stack is less than 16 bytes aslink trows a
4697 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4698 the 8051. Option 'y' for memory summary output file.
4700 Changes to sdcc (All the changes are marked with 'JCF'):
4702 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4704 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4705 overlaying area for it (uses RegBankUsed[4]).
4707 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4708 bank zero as used by default. By default aslink locates the stack
4709 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4710 the creation of the .mem file. Delegates the allocation of data area
4711 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4712 the begining of the stack area to aslink.
4714 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4715 glue() in SDCCglue.c creates an area for it.
4717 2002-09-03 Borut Razem <borut.razem AT siol.net>
4718 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4719 sdcc/src/pic/glue.c:
4720 introduced atexit() handler for teporay files removal in case of
4721 errors, assertions, ...
4723 2002-08-29 Borut Razem <borut.razem AT siol.net>
4724 * sdcc/support/cpp2/auto-host_vc_in.h:
4725 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4726 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4727 Maybe there is a similar problem with BORLANDC? It should be checked!
4729 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4730 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4731 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4732 was not executed, and the compiler (cl) launched a warning:
4733 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4735 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4736 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4738 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4739 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4741 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4742 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

4745 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4746 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4747 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4748 - added Release configuration in VS projects
4749 - review of compiler an linker options
4750 - VC .exe files are generated in bin_vc directory, not to interfere
4751 with binaries generated from other projects (cygwin, mingw, bcc ...)
4753 * sdcc/src/yacc.dsp: added
4755 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4756 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4757 and insert the version number definitions from .version
4759 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4761 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4762 added - genarate auto-host.h using auto-host_vc_in.h as template
4765 removed from CVS, generated automatically
4767 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4768 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4770 2002-08-11 Borut Razem <borut.razem AT siol.net>
4771 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4773 2002-08-10 Borut Razem <borut.razem AT siol.net>
4774 * src/SDCCmain.c (main):
4775 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4776 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4777 The consequence was that some temporary files were not removed.
4780 unification of code in functions tempfilename() and tempfile():
4781 function tempnam() is defined in Visual Studio 6.0 and .NET
4783 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4785 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4786 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4787 - removed compiler command line option /WX: Treats all warnings as errors
4788 - update a list of source files, included into the project
4790 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4791 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4792 changed project type to Generic Project so that can be correcly converted to VS.NET project
4794 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4796 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
4798 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

4989 Previous fix was not good. basic blocks that have "break" or "return" are
4990 not really partof a loop , but live ranges used in these blocks should
4991 be live thru the entire loop, so set partOfLoop but don't add them to
