1233 loaded with the linker search paths (-L arguments) and the libraries
1234 to be linked with the current source (-l arguments). Changes
1235 currently will affect only the pic16 port.
1236 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1237 include path the port specific paths and port specific libraries,
1238 * gplink command now contains the $3 argument,
1239 * src/pic16/device.h,

1256 Documenting changes from previous commits.
1257 * configure.in (version 1.56),
1258 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1259 when generating output files to configure the pic16 library,
1260 but now I've commented it out, since gputils aren't installed in the
1261 SF compile farm, so library won't compile
1263 * device/lib/Makefile.in (version 1.56): initially I've added in
1264 target 'all' the prerequestive 'model-pic16' so it compiled the
1265 pic16 library, but now I've commented it out for the same reasons
1267 * added targets 'model-pic16' and 'objects-pic16' to compile the
1269 * added target 'port-specific-objects-pic16' to handle the
1270 generated libraries and copy them into the build/ directory
1271 * added target 'clean-intermediate-pic16' to clean intermediate
1272 files into pic16 directory
1273 * in target 'installdirs' added line to create directory pic16 in

1295 option so that it actually works. Made it specific to the z80, since
1296 the gbz80 doesn't have these kinds of I/O ports.
1298 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1522 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1524 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
1525 (default behaviour).
1527 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1529 A python script to validate compiler diagnostic messages. It can be
1530 used to verify that sdcc complains about bad c source code and

1553 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
1555 * sdcc.spec: updated

1559 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
1560 * src/mcs51/gen.c (genRightShift): fixed bug #870788
1561 * src/ds390/gen.c (genRightShift): fixed bug #870788

1564 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1566 PIC16 port related changes:
1567 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1568 added variable stackPos,
1570 * gen.c: genCall, assignResultValue: added support for
1571 pushing/retrieving function parameters to/from stack,
1572 genFunction,genEndFunction: setup stack frame for the
1574 genAddrOf: will be changed according to bug 863624
1576 * added files genutils.c and genutils.h which contain gen*
1577 debugged and optimised functions extracted from gen.c
1579 * glue.c: added variable 'externs' which holds extern symbols,
1580 pic16emitRegularMap: is modified to properly handle relocatable
1581 symbols under the new scheme,
1582 pic16createInterruptVect: is modified
1583 pic16printPublics: is modified to emit 'global' assembler directives,
1584 added pic16_printExterns to print extern symbols,
1585 pic16glue: initializes stack/frame pointer in the beginning of
1586 the assembly output. Temporary hack, will be corrected later,
1587 because gplink yet does not support stack and SDCC does not
1588 yet support a type of crt0.o object to create the final binary.
1590 * Removed many lines that contain 8051 legacy code.
1591 * The code is finally placed under a 'code' directive.
1592 * Added port specific options.
1594 * _process_pragma: simplified since now we do not need *special*
1595 include file to define SFR registers. But a separate header
1596 will be needed. This will be developed later.
1597 * _pic16_parseOptions: added, parses port specific options:
1598 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1599 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1600 --preplace-udata-with=
1602 * _pic16_setDefaultOptions: modified to initialize section names,
1603 but hack is temporarly out of order since it needs improvement.
1604 * _pic16_genAssemblerPreamble: configuration words are emitted by
1605 their address instead of their name. This part is incomplete and
1606 supports only the 18Fxx2 devices. Other devices will emit an error
1607 during assembly since they do not contain the same set of config
1609 * _pic16_genIVT: is modified,
1611 * pcode.c: added definitions for some hardware registers that are needed
1613 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1614 All PCI entries are updated. Now LFSR is supported.
1615 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1616 * added pic16_newpCodeOpLit2 to support instructions with
1617 two literal arguments
1618 * pic16_pCode2str: corrected code that emits assembler instructions
1619 with two literal operands and those that have an access bit modifier
1620 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1621 this fixes a bug which caused some labels to be lost, when an
1622 assembler directive was added, i.e. banksel,
1623 * pic16_FixRegisterBanking: improved logic that causes the insertion
1625 * InlineFunction: functions that are called once, are not any more
1626 inlined. This can be a port option in the future,
1628 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1630 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1631 hold the corresponding uninitialized symbols,
1632 * pic16_allocProcessorRegister: registers have explicit marked the
1634 * pic16_allocInternalRegister: registers are explicit marked as
1636 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1637 processing list, so bit registers were lost,
1640 * ralloc.h: added field 'accessBank' and original symbol operand
1641 in register definition,
1642 * removed the field isMapped from register definition,
1644 ** Several functions have been removed from various sources:
1645 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1646 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1647 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1648 pic16_assignRelocatableRegisters
1650 ** others have been introduced:
1651 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
1652 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
1654 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
1656 * support/scripts/inc2h.pl: changed definition of BIT_AT
1657 to emit 'sbit at' instead of 'bit at'. This was a request.
1659 PIC16 port related preliminary changes:
1660 * gen.c: prefixed function popRegFromString with
1661 pic16_ and all references to it corrected
1662 * pcode.c: all pic16_pc_* hardware registers prefixed
1663 with underscore (_),
1664 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1665 * ralloc.c: newReg(): when register is REG_SFR then
1666 set address to rIdx,
1667 pic16_allocProcessorRegister(): marks register wasUsed=0
1668 pic16_writeUsedRegs(): added a call to assign processor
1669 registers via pic16_assignFixedRegisters
1671 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1673 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1674 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1675 variables in unused register banks. Also the SSEG is placed
1676 wherever there is enough space for it, and IDATA can be anywhere
1677 in internal RAM. For now compile using -Wl-Y[stack_size].
1678 The mem file is different for this option as well, since it
1679 makes no sense of talking about DSEG lenght.
1681 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1683 * src/SDCClrange.c: fixed bug 869095 that caused segfault
1684 in certain cases, e.g. when ROM assignment, patch provided
1685 from Albert den Haan.
1687 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2689 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
2690 fetching of the pointer
2691 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
2692 copied from genNearPointerSet()
2693 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
2694 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
2695 If they pop r0/r1 they must be called in the opposite order than aopOp().
2696 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
2697 (resp. --stack-auto), prepared for --xstack

2708 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
2710 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2711 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
2712 type for bits was changed. It resulted in bit variables becoming
2713 global, which is not permitted in PIC 14 assembly output.
2715 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2717 * doc/sdccman.lyx: various additions and updates. Rearranged sections

2730 A few small changes that speed up the peephole optimizer.
2734 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2736 Try to make the peephole optimizer smarter by maintaining
2737 an association between the assembly source code and the
2738 iCodes that originated them. Put this information to use
2739 with a new peephole rule condition "notVolatile" so that
2740 the rules can be aggressive yet still safe.
2745 * src/mcs51/peeph.def
2747 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2751 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
2752 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
2753 if the left or right operand symbols have the accuse flag set.
2755 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2757 Changed the type of the result of the ! (NOT) operator to char;
2758 previously it returned the same type as the source. This allows
2759 us to eliminate all the genFloatNot functions (all of its target
2760 implementations were very buggy) since !float can use the same
2763 * src/SDCCicode.c (ast2iCode): ! returns char
2764 * src/mcs51/gen.c (genNot, genNotFloat),
2765 * src/ds390/gen.c (genNot, genNotFloat),
2766 * src/z80/gen.c (genNot, genNotFloat),
2767 * src/pic/gen.c (genNot, genNotFloat),

2770 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
2772 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2773 1. Interrupt would not compile properly. Ensure PCLATH register is saved
2774 during interrupts. Ensure WSAVE is located at a shared bank address.
2775 2. Fixed page selection in some places
2776 3. Fixed BTFSS/C to where necessary use registers directly and not simply
2777 the registers name strings.
2778 4. Fixed "signed / unsigned compare" compiler warnings.
2779 5. The PIC port manages its own allocation of the general purpose
2780 registers, but makes no attempt to reuse them. As a result when
2781 compiling it soon runs out of general purpose registers. Some
2782 additional code was added to the files pcode.c and device.c to walk
2783 through the function call tree and rename the registers so that they
2793 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
2794 genPlus() & genMinus() when the result is the same as left or right

2800 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2802 Made bitfield a distinct type from bit so that bitfields
2803 convert as per ANSI C and bits retain their traditional
2804 boolean style behaviour. Implemented bitfield support in
2812 * src/ds390/gen.c: bit v bitfield split
2813 * src/z80/gen.c: New support for bitfields
2814 * support/regression/tests/bitfields.c: reenabled z80,
2817 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2819 Rules 246.x, 247.x relate to bitfields, the others speed up
2820 access to xdata mapped I/O devices.
2822 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
2824 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2826 Cleaned up genPackBits and genUnpackBits and added two helper
2827 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
2828 for literal assignments in genPackBits (thanks to Frieder for
2834 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2836 Fixed bug #748310 (pointer to function type mishandled when the
2837 function name is omitted). Also fixed a SIGSEGV when a function
2838 attribute (reentrant, etc) is used on a non-function or on a
2839 function but misplaced before the parameter list.
2841 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
2843 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
2844 * support/Util/SDCCerr.h,
2845 * support/Util/SDCCerr.c: Added func attr misuse error msg

2866 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2868 Made the constant following the "interrupt" keyword optional. If
2869 omitted, the function will not automatically be given an entry
2870 in the interrupt vector table (similar to #pragma NOIV, but
2871 less syntacticly kludgy). The interrupt number is also now
2872 range checked. Also fixed a bug in the high order bit example

2888 * src/SDCCsymt.c (computeType): literals are handled the same way as any
2890 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
2891 be re-activated by defining REDUCE_LITERALS)
2892 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
2893 unsigned, but are signed by default
2894 * src/SDCCval.c (constVal): rearranged
2895 * src/SDCCval.c (valMod): preliminary fix
2896 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3402 added if/endif conditional macros to remove options help
3403 messages from optionsTable when a port is not configured, added
3404 support for the PIc16 port in the ports table, when executing
3405 the compiler with no port specified on command line, a default
3406 port is selected with the new macro DEFAULT_PORT which is
3407 defined in port.h, in setDefaultOptions() linkOptions is removed
3408 from initialization assignment, since now it is a set,
3409 parseCmdLine uses setParseWithComma for linkOptions, in
3410 linkEdit() linkOptions are accessed with new function indexSet()
3411 which returns the i'th item of a set variable. See SDCCset.c, in
3412 linkEdit() when calling buildCmdLine(), added linkOptions as
3413 last argument. Now users can pass arguments to gplink via the
3414 -Wl option, main() uses pic16glue() to glue up pic16 programs

3428 gpasm complaining and test the linkage with gplink, _linkCmd and
3429 _asmCmd changed to be more gplink and gpasm friendly
3430 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3431 produced an error when parsed, peep rule 12 is added to utilize
3432 movff, but it is commented out since the pCode does not support
3433 yet a command with 2 address arguments
3435 2003-05-18 <johan AT balder>
3437 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

3462 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
3464 2003-05-11 Borut Razem <borut.razem AT siol.net>
3466 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

4472 * src/SDCCicode.c: fixed array add
4474 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
4475 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
4476 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
4478 2003-01-04 <johan AT balder>
4480 * src/SDCCval.c (getNelements): fixed the initialized array of structures
4482 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4483 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
4485 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

4495 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4496 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4498 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4500 * in \sdcc\as\mcs51\ changed these files in order to create an
4501 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4502 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4503 following files to include the previous two files: aslink.dsp,
4504 Makefile.aslink, Makefile.bcc, and Makefile.in.
4506 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
4507 .adb instead of .cdb
4509 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4511 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
4512 value from option --iram-size.
4514 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4516 * \sdcc\as\mcs51\lklist.c: added boundary check before using
4519 2002-09-18 <wiml AT hhhh.org>
4521 * SDCClrange.h: exposed setFromRange() and setToRange()
4522 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
4523 packRegsForAccUse() (bug 542397)
4524 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
4525 multiple times and emitting the fetch operations more than once
4526 added aopGetUsesAcc() function to allow binary operators to
4527 fetch their operands in the correct order; made genMinus() emit
4528 compact code for X = LITERAL - Y
4530 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4531 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
4532 sprintf() in line 1267.
4534 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4535 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
4538 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4539 Changes to aslink (All the changes are marked with 'JCF'):
4541 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
4544 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
4545 area BSEG. Also moves, if possible, the DATA area down into the internal
4546 ram so more space is available.
4548 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
4551 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
4552 not bytes. Function summary() which creates a memory usage summary
4553 file with extension .mem. Reports of overlaping stack and small stack
4554 size. If the space for the stack is less than 16 bytes aslink trows a
4557 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
4558 the 8051. Option 'y' for memory summary output file.
4560 Changes to sdcc (All the changes are marked with 'JCF'):
4562 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
4564 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
4565 overlaying area for it (uses RegBankUsed[4]).
4567 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4568 bank zero as used by default. By default aslink locates the stack
4569 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4570 the creation of the .mem file. Delegates the allocation of data area
4571 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4572 the begining of the stack area to aslink.
4574 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4575 glue() in SDCCglue.c creates an area for it.
4577 2002-09-03 Borut Razem <borut.razem AT siol.net>
4578 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4579 sdcc/src/pic/glue.c:
4580 introduced atexit() handler for teporay files removal in case of
4581 errors, assertions, ...
4583 2002-08-29 Borut Razem <borut.razem AT siol.net>
4584 * sdcc/support/cpp2/auto-host_vc_in.h:
4585 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4586 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4587 Maybe there is a similar problem with BORLANDC? It should be checked!
4589 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4590 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4591 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4592 was not executed, and the compiler (cl) launched a warning:
4593 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4595 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4596 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4598 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4599 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4601 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4602 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
4603 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
4604 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4605 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4606 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4607 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4608 - added Release configuration in VS projects
4609 - review of compiler an linker options
4610 - VC .exe files are generated in bin_vc directory, not to interfere
4611 with binaries generated from other projects (cygwin, mingw, bcc ...)
4613 * sdcc/src/yacc.dsp: added
4615 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4616 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4617 and insert the version number definitions from .version
4619 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4621 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4622 added - genarate auto-host.h using auto-host_vc_in.h as template
4625 removed from CVS, generated automatically
4627 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4628 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4630 2002-08-11 Borut Razem <borut.razem AT siol.net>
4631 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4633 2002-08-10 Borut Razem <borut.razem AT siol.net>
4634 * src/SDCCmain.c (main):
4635 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4636 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4637 The consequence was that some temporary files were not removed.
4640 unification of code in functions tempfilename() and tempfile():
4641 function tempnam() is defined in Visual Studio 6.0 and .NET
4643 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4645 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4646 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4647 - removed compiler command line option /WX: Treats all warnings as errors
4648 - update a list of source files, included into the project
4650 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4651 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4652 changed project type to Generic Project so that can be correcly converted to VS.NET project
4654 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4656 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
4658 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
4660 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
4661 added return 0 statements after assert() to make compiler happy
4663 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4664 added newline in the def file to keep MSC compiler satisfied
4666 * sdcc/src/z80/gen.c:
4667 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4668 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4669 - solved MSC error in function aopDump()
4671 * sdcc_vc.h: define PREFIX as "\\sdcc"
4673 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
4674 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

4713 2002-03-28 Johan Knol <johan AT balder>
4715 * src/SDCCval.c: fixed bug #532436
4717 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4719 Added "char *Processor" field to the port structure.
4722 Added -p option. Allows port dependent processor to be specified.
4725 Initialized the new field char *Processor field to NULL in all ports
4728 Compiler generated registers for interrupt context saving
4729 were not getting allocated.
4731 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
4734 Fixed left shift. Will promote the left side of a left shift
4735 if a) left shifting more than size of operand or b) when assigned
4736 to something size > size of left side
4738 2002-03-14 Scott Dattalo <scott AT dattalo.com>
4740 tons of changes. Register allocation has been
4741 rewritten. Added customization for the various PICs. Flow

4848 * sdcc/src/SDCCloop.c:
4849 Previous fix was not good. basic blocks that have "break" or "return" are
4850 not really partof a loop , but live ranges used in these blocks should
4851 be live thru the entire loop, so set partOfLoop but don't add them to
