1229 loaded with the linker search paths (-L arguments) and the libraries
1230 to be linked with the current source (-l arguments). Changes
1231 currently will affect only the pic16 port.
1232 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1233 include path the port specific paths and port specific libraries,
1234 * gplink command now contains the $3 argument,
1235 * src/pic16/device.h,
1236 * src/pic16/device.c,: structure PIC_device is made public and

1252 Documenting changes from previous commits.
1253 * configure.in (version 1.56),
1254 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1255 when generating output files to configure the pic16 library,
1256 but now I've commented it out, since gputils aren't installed in the
1257 SF compile farm, so library won't compile
1259 * device/lib/Makefile.in (version 1.56): initially I've added in
1260 target 'all' the prerequestive 'model-pic16' so it compiled the
1261 pic16 library, but now I've commented it out for the same reasons
1263 * added targets 'model-pic16' and 'objects-pic16' to compile the
1265 * added target 'port-specific-objects-pic16' to handle the
1266 generated libraries and copy them into the build/ directory
1267 * added target 'clean-intermediate-pic16' to clean intermediate
1268 files into pic16 directory
1269 * in target 'installdirs' added line to create directory pic16 in

1518 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1520 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1521 (default behaviour).
1523 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1525 A python script to validate compiler diagnostic messages. It can be
1526 used to verify that sdcc complains about bad c source code and
1527 gives a good location of the error.
1528 * support/valdiag/Makefile,
1529 * support/valdiag/valdiag.py,

1547 Bug reported from Jesus Calvino-Fraga
1549 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1551 * sdcc.spec: updated
1552 * device/include/Makefile.in: don't install CVS directories
1553 * device/lib/Makefile.in: added removal of CVS directories after install
1554 * doc/Makefile: fixed install, added local_icons
1555 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1556 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1557 * src/ds390/gen.c (genRightShift): fixed bug #870788
1558 * src/SDCCast.c (decorateType): fixed bug #870781
1560 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1562 PIC16 port related changes:
1563 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1564 added variable stackPos,
1566 * gen.c: genCall, assignResultValue: added support for
1567 pushing/retrieving function parameters to/from stack,
1568 genFunction,genEndFunction: setup stack frame for the
1570 genAddrOf: will be changed according to bug 863624
1572 * added files genutils.c and genutils.h which contain gen*
1573 debugged and optimised functions extracted from gen.c
1575 * glue.c: added variable 'externs' which holds extern symbols,
1576 pic16emitRegularMap: is modified to properly handle relocatable
1577 symbols under the new scheme,
1578 pic16createInterruptVect: is modified
1579 pic16printPublics: is modified to emit 'global' assembler directives,
1580 added pic16_printExterns to print extern symbols,
1581 pic16glue: initializes stack/frame pointer in the beginning of
1582 the assembly output. Temporary hack, will be corrected later,
1583 because gplink yet does not support stack and SDCC does not
1584 yet support a type of crt0.o object to create the final binary.
1586 * Removed many lines that contain 8051 legacy code.
1587 * The code is finally placed under a 'code' directive.
1588 * Added port specific options.
1590 * _process_pragma: simplified since now we do not need *special*
1591 include file to define SFR registers. But a separate header
1592 will be needed. This will be developed later.
1593 * _pic16_parseOptions: added, parses port specific options:
1594 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1595 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1596 --preplace-udata-with=
1598 * _pic16_setDefaultOptions: modified to initialize section names,
1599 but hack is temporarly out of order since it needs improvement.
1600 * _pic16_genAssemblerPreamble: configuration words are emitted by
1601 their address instead of their name. This part is incomplete and
1602 supports only the 18Fxx2 devices. Other devices will emit an error
1603 during assembly since they do not contain the same set of config
1605 * _pic16_genIVT: is modified,
1607 * pcode.c: added definitions for some hardware registers that are needed
1609 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1610 All PCI entries are updated. Now LFSR is supported.
1611 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1612 * added pic16_newpCodeOpLit2 to support instructions with
1613 two literal arguments
1614 * pic16_pCode2str: corrected code that emits assembler instructions
1615 with two literal operands and those that have an access bit modifier
1616 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1617 this fixes a bug which caused some labels to be lost, when an
1618 assembler directive was added, i.e. banksel,
1619 * pic16_FixRegisterBanking: improved logic that causes the insertion
1621 * InlineFunction: functions that are called once, are not any more
1622 inlined. This can be a port option in the future,
1624 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1626 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1627 hold the corresponding uninitialized symbols,
1628 * pic16_allocProcessorRegister: registers have explicit marked the
1630 * pic16_allocInternalRegister: registers are explicit marked as
1632 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1633 processing list, so bit registers were lost,
1636 * ralloc.h: added field 'accessBank' and original symbol operand
1637 in register definition,
1638 * removed the field isMapped from register definition,
1640 ** Several functions have been removed from various sources:
1641 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1642 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1643 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1644 pic16_assignRelocatableRegisters
1646 ** others have been introduced:
1647 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1648 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1650 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1652 * support/scripts/inc2h.pl: changed definition of BIT_AT
1653 to emit 'sbit at' instead of 'bit at'. This was a request.
1655 PIC16 port related preliminary changes:
1656 * gen.c: prefixed function popRegFromString with
1657 pic16_ and all references to it corrected
1658 * pcode.c: all pic16_pc_* hardware registers prefixed
1659 with underscore (_),
1660 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1661 * ralloc.c: newReg(): when register is REG_SFR then
1662 set address to rIdx,
1663 pic16_allocProcessorRegister(): marks register wasUsed=0
1664 pic16_writeUsedRegs(): added a call to assign processor
1665 registers via pic16_assignFixedRegisters
1667 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1669 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1670 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1671 variables in unused register banks. Also the SSEG is placed
1672 wherever there is enough space for it, and IDATA can be anywhere
1673 in internal RAM. For now compile using -Wl-Y[stack_size].
1674 The mem file is different for this option as well, since it
1675 makes no sense of talking about DSEG lenght.
1677 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1679 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1680 in certain cases, e.g. when ROM assignment, patch provided
1681 from Albert den Haan.
1683 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2686 fetching of the pointer
2687 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
2688 copied from genNearPointerSet()
2689 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
2690 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
2691 If they pop r0/r1 they must be called in the opposite order than aopOp().
2692 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
2693 (resp. --stack-auto), prepared for --xstack

2706 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2707 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
2708 type for bits was changed. It resulted in bit variables becoming
2709 global, which is not permitted in PIC 14 assembly output.
2711 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2713 * doc/sdccman.lyx: various additions and updates. Rearranged sections

2726 A few small changes that speed up the peephole optimizer.
2730 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2732 Try to make the peephole optimizer smarter by maintaining
2733 an association between the assembly source code and the
2734 iCodes that originated them. Put this information to use
2735 with a new peephole rule condition "notVolatile" so that
2736 the rules can be aggressive yet still safe.
2741 * src/mcs51/peeph.def
2743 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2747 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2748 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2749 if the left or right operand symbols have the accuse flag set.
2751 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2753 Changed the type of the result of the ! (NOT) operator to char;
2754 previously it returned the same type as the source. This allows
2755 us to eliminate all the genFloatNot functions (all of its target
2756 implementations were very buggy) since !float can use the same
2759 * src/SDCCicode.c (ast2iCode): ! returns char

2766 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
2768 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2769 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2770 during interrupts. Ensure WSAVE is located at a shared bank address.
2771 2. Fixed page selection in some places
2772 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2773 the registers name strings.
2774 4. Fixed "signed / unsigned compare" compiler warnings.
2775 5. The PIC port manages its own allocation of the general purpose
2776 registers, but makes no attempt to reuse them. As a result when
2777 compiling it soon runs out of general purpose registers. Some
2778 additional code was added to the files pcode.c and device.c to walk
2779 through the function call tree and rename the registers so that they
2789 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2790 genPlus() & genMinus() when the result is the same as left or right

2796 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2798 Made bitfield a distinct type from bit so that bitfields
2799 convert as per ANSI C and bits retain their traditional
2800 boolean style behaviour. Implemented bitfield support in
2808 * src/ds390/gen.c: bit v bitfield split
2809 * src/z80/gen.c: New support for bitfields
2810 * support/regression/tests/bitfields.c: reenabled z80,
2813 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2815 Rules 246.x, 247.x relate to bitfields, the others speed up
2816 access to xdata mapped I/O devices.
2818 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2820 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2822 Cleaned up genPackBits and genUnpackBits and added two helper
2823 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2824 for literal assignments in genPackBits (thanks to Frieder for
2830 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2832 Fixed bug #748310 (pointer to function type mishandled when the
2833 function name is omitted). Also fixed a SIGSEGV when a function
2834 attribute (reentrant, etc) is used on a non-function or on a
2835 function but misplaced before the parameter list.
2837 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
2839 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
2840 * support/Util/SDCCerr.h,
2841 * support/Util/SDCCerr.c: Added func attr misuse error msg

2862 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2864 Made the constant following the "interrupt" keyword optional. If
2865 omitted, the function will not automatically be given an entry
2866 in the interrupt vector table (similar to #pragma NOIV, but
2867 less syntacticly kludgy). The interrupt number is also now
2868 range checked. Also fixed a bug in the high order bit example

2884 * src/SDCCsymt.c (computeType): literals are handled the same way as any
2886 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
2887 be re-activated by defining REDUCE_LITERALS)
2888 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
2889 unsigned, but are signed by default
2890 * src/SDCCval.c (constVal): rearranged
2891 * src/SDCCval.c (valMod): preliminary fix
2892 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3398 added if/endif conditional macros to remove options help
3399 messages from optionsTable when a port is not configured, added
3400 support for the PIc16 port in the ports table, when executing
3401 the compiler with no port specified on command line, a default
3402 port is selected with the new macro DEFAULT_PORT which is
3403 defined in port.h, in setDefaultOptions() linkOptions is removed
3404 from initialization assignment, since now it is a set,
3405 parseCmdLine uses setParseWithComma for linkOptions, in
3406 linkEdit() linkOptions are accessed with new function indexSet()
3407 which returns the i'th item of a set variable. See SDCCset.c, in
3408 linkEdit() when calling buildCmdLine(), added linkOptions as
3409 last argument. Now users can pass arguments to gplink via the
3410 -Wl option, main() uses pic16glue() to glue up pic16 programs

3424 gpasm complaining and test the linkage with gplink, _linkCmd and
3425 _asmCmd changed to be more gplink and gpasm friendly
3426 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3427 produced an error when parsed, peep rule 12 is added to utilize
3428 movff, but it is commented out since the pCode does not support
3429 yet a command with 2 address arguments
3431 2003-05-18 <johan AT balder>
3433 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

3456 2003-05-12 Borut Razem <borut.razem AT siol.net>
3458 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
3460 2003-05-11 Borut Razem <borut.razem AT siol.net>
3462 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3463 the path of bin directory, so that PATH is the only env. variable, which has to be set

4468 * src/SDCCicode.c: fixed array add
4470 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
4471 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
4472 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
4474 2003-01-04 <johan AT balder>
4476 * src/SDCCval.c (getNelements): fixed the initialized array of structures
4478 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4479 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
4481 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

4491 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4492 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4494 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4496 * in \sdcc\as\mcs51\ changed these files in order to create an
4497 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4498 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4499 following files to include the previous two files: aslink.dsp,
4500 Makefile.aslink, Makefile.bcc, and Makefile.in.
4502 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4503 .adb instead of .cdb
4505 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4507 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4508 value from option --iram-size.
4510 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4512 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4515 2002-09-18 <wiml AT hhhh.org>
4517 * SDCClrange.h: exposed setFromRange() and setToRange()
4518 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4519 packRegsForAccUse() (bug 542397)
4520 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4521 multiple times and emitting the fetch operations more than once
4522 added aopGetUsesAcc() function to allow binary operators to
4523 fetch their operands in the correct order; made genMinus() emit
4524 compact code for X = LITERAL - Y
4526 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4527 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4528 sprintf() in line 1267.
4530 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4531 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4534 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4535 Changes to aslink (All the changes are marked with 'JCF'):
4537 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4540 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4541 area BSEG. Also moves, if possible, the DATA area down into the internal
4542 ram so more space is available.
4544 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4547 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4548 not bytes. Function summary() which creates a memory usage summary
4549 file with extension .mem. Reports of overlaping stack and small stack
4550 size. If the space for the stack is less than 16 bytes aslink trows a
4553 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4554 the 8051. Option 'y' for memory summary output file.
4556 Changes to sdcc (All the changes are marked with 'JCF'):
4558 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4560 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4561 overlaying area for it (uses RegBankUsed[4]).
4563 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4564 bank zero as used by default. By default aslink locates the stack
4565 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4566 the creation of the .mem file. Delegates the allocation of data area
4567 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4568 the begining of the stack area to aslink.
4570 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4571 glue() in SDCCglue.c creates an area for it.
4573 2002-09-03 Borut Razem <borut.razem AT siol.net>
4574 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4575 sdcc/src/pic/glue.c:
4576 introduced atexit() handler for teporay files removal in case of
4577 errors, assertions, ...
4579 2002-08-29 Borut Razem <borut.razem AT siol.net>
4580 * sdcc/support/cpp2/auto-host_vc_in.h:
4581 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4582 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4583 Maybe there is a similar problem with BORLANDC? It should be checked!
4585 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4586 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4587 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4588 was not executed, and the compiler (cl) launched a warning:
4589 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4591 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4592 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4594 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4595 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4597 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4598 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
4599 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
4600 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4601 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4602 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4603 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4604 - added Release configuration in VS projects
4605 - review of compiler an linker options
4606 - VC .exe files are generated in bin_vc directory, not to interfere
4607 with binaries generated from other projects (cygwin, mingw, bcc ...)
4609 * sdcc/src/yacc.dsp: added
4611 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4612 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4613 and insert the version number definitions from .version
4615 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4617 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4618 added - genarate auto-host.h using auto-host_vc_in.h as template
4621 removed from CVS, generated automatically
4623 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4624 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4626 2002-08-11 Borut Razem <borut.razem AT siol.net>
4627 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4629 2002-08-10 Borut Razem <borut.razem AT siol.net>
4630 * src/SDCCmain.c (main):
4631 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4632 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4633 The consequence was that some temporary files were not removed.
4636 unification of code in functions tempfilename() and tempfile():
4637 function tempnam() is defined in Visual Studio 6.0 and .NET
4639 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4641 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4642 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4643 - removed compiler command line option /WX: Treats all warnings as errors
4644 - update a list of source files, included into the project
4646 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4647 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4648 changed project type to Generic Project so that can be correcly converted to VS.NET project
4650 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4652 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
4654 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
4656 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
4657 added return 0 statements after assert() to make compiler happy
4659 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4660 added newline in the def file to keep MSC compiler satisfied
4662 * sdcc/src/z80/gen.c:
4663 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4664 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4665 - solved MSC error in function aopDump()
4667 * sdcc_vc.h: define PREFIX as "\\sdcc"
4669 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
4670 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

4709 2002-03-28 Johan Knol <johan AT balder>
4711 * src/SDCCval.c: fixed bug #532436
4713 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4715 Added "char *Processor" field to the port structure.
4718 Added -p option. Allows port dependent processor to be specified.
4721 Initialized the new field char *Processor field to NULL in all ports
4724 Compiler generated registers for interrupt context saving
4725 were not getting allocated.
4727 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
4730 Fixed left shift. Will promote the left side of a left shift
4731 if a) left shifting more than size of operand or b) when assigned
4732 to something size > size of left side
4734 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4736 tons of changes. Register allocation has been
4737 rewritten. Added customization for the various PICs. Flow
4738 analysis is restructured. ...

4844 * sdcc/src/SDCCloop.c:
4845 Previous fix was not good. basic blocks that have "break" or "return" are
4846 not really partof a loop , but live ranges used in these blocks should
4847 be live thru the entire loop, so set partOfLoop but don't add them to
