1411 (valLogicAndOr): result is unsigned
1412 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1413 * src/SDCCsymt.c (computeType),
1414 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
1415 must not cause an unsigned operation
1416 * src/pic/glue (pic14emitRegularMap),
1417 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
1419 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
1421 * src/pic/pcode.c (PCodeID): commented out left over debug code
1423 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
1425 * support/valdiag/tests/overflow.c: added shift tests
1433 * src/pic/pcodepeep.c,
1434 * src/pic/pcoderegs.c,
1436 * src/pic/ralloc.h: applied patch from Slade Rich;
1437 added support for multiple code pages and multiple RAM banks on the
1438 PIC 14 port. The ASM files now no longer simply assume all the
1439 code / RAM are in the same page / bank. This means the linker can
1440 safely allocate code/RAM of separate ASM files to different pages/banks.
1441 * doc/sdccman.lyx: added Slade's tips
1442 * src/mcs51/peeph.def: fixed bug #880768

1451 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
1454 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
1455 strtof is not part of C89 and isn't included with Mac OS X.
1457 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1459 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

1484 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1486 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1487 loaded with the linker search paths (-L arguments) and the libraries
1488 to be linked with the current source (-l arguments). Changes
1489 currently will affect only the pic16 port.
1490 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1491 include path the port specific paths and port specific libraries,
1492 * gplink command now contains the $3 argument,
1493 * src/pic16/device.h,
1494 * src/pic16/device.c,: structure PIC_device is made public and
1495 renamed to PIC16_device, the same for variable Pics which is renamed
1496 to Pics16. Updated all references to them.

1508 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
1510 Documenting changes from previous commits.
1511 * configure.in (version 1.56),
1512 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1513 when generating output files to configure the pic16 library,
1514 but now I've commented it out, since gputils aren't installed in the
1515 SF compile farm, so library won't compile
1517 * device/lib/Makefile.in (version 1.56): initially I've added in
1518 target 'all' the prerequestive 'model-pic16' so it compiled the
1519 pic16 library, but now I've commented it out for the same reasons
1521 * added targets 'model-pic16' and 'objects-pic16' to compile the
1523 * added target 'port-specific-objects-pic16' to handle the
1524 generated libraries and copy them into the build/ directory
1525 * added target 'clean-intermediate-pic16' to clean intermediate
1526 files into pic16 directory
1527 * in target 'installdirs' added line to create directory pic16 in
1528 the installation path
1530 * device/include/Makefile.in (version 1.11): in target 'install'
1531 added lines to copy all header files to installation path,
1532 * in target 'installdirs' added line create directory for pic16
1533 headers in the installation path

1548 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1549 option so that it actually works. Made it specific to the z80, since
1550 the gbz80 doesn't have these kinds of I/O ports.
1552 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1554 * device/include/z180.h,

1576 Mainly changes to support compilation of the device libraries
1577 * src/pic16/device.c: stack is allocated via symbol and not
1578 via literal number. The symbol is placed in the corresponding
1579 position of the data ram
1580 * (pic16_dump_section): relocatable and absolute uninitialized
1581 data are now emitted in sorted order to reduce section naming,
1582 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1583 weren't marked as being in the access bank,
1585 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1587 Added portion of GNU PIC Library under the directory
1588 device/include/pic16 and device/lib/pic16. These files
1589 contain the declarations of SFRs for the PIC18Fxx2 devices.
1590 The directory is initialized via configure from toplevel.
1592 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

1620 all over. Telling LaTeX to be less strict with word spacing
1621 to better keep the right margin. Changed some notes about
1622 maintainance of the ports in section 3.2.1 - is it OK like this?
1624 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

1662 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
1664 * src/pic16/peeph.def: all peepholes with movff are commented out,
1665 because there is a problem in the pcode peep optimizer,
1666 * src/pic16/ralloc.c: the register allocator can now reuse local

1818 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
1820 PIC16 port related changes:
1821 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
1822 added variable stackPos,
1824 * gen.c: genCall, assignResultValue: added support for
1825 pushing/retrieving function parameters to/from stack,
1826 genFunction,genEndFunction: setup stack frame for the
1828 genAddrOf: will be changed according to bug 863624
1830 * added files genutils.c and genutils.h which contain gen*
1831 debugged and optimised functions extracted from gen.c
1833 * glue.c: added variable 'externs' which holds extern symbols,
1834 pic16emitRegularMap: is modified to properly handle relocatable
1835 symbols under the new scheme,
1836 pic16createInterruptVect: is modified
1837 pic16printPublics: is modified to emit 'global' assembler directives,
1838 added pic16_printExterns to print extern symbols,
1839 pic16glue: initializes stack/frame pointer in the beginning of
1840 the assembly output. Temporary hack, will be corrected later,
1841 because gplink yet does not support stack and SDCC does not
1842 yet support a type of crt0.o object to create the final binary.
1844 * Removed many lines that contain 8051 legacy code.
1845 * The code is finally placed under a 'code' directive.
1846 * Added port specific options.
1848 * _process_pragma: simplified since now we do not need *special*
1849 include file to define SFR registers. But a separate header
1850 will be needed. This will be developed later.
1851 * _pic16_parseOptions: added, parses port specific options:
1852 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
1853 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
1854 --preplace-udata-with=
1856 * _pic16_setDefaultOptions: modified to initialize section names,
1857 but hack is temporarly out of order since it needs improvement.
1858 * _pic16_genAssemblerPreamble: configuration words are emitted by
1859 their address instead of their name. This part is incomplete and
1860 supports only the 18Fxx2 devices. Other devices will emit an error
1861 during assembly since they do not contain the same set of config
1863 * _pic16_genIVT: is modified,
1865 * pcode.c: added definitions for some hardware registers that are needed
1867 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
1868 All PCI entries are updated. Now LFSR is supported.
1869 * Removed pic16_pciTRIS is mentioned by mdubuc in source
1870 * added pic16_newpCodeOpLit2 to support instructions with
1871 two literal arguments
1872 * pic16_pCode2str: corrected code that emits assembler instructions
1873 with two literal operands and those that have an access bit modifier
1874 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
1875 this fixes a bug which caused some labels to be lost, when an
1876 assembler directive was added, i.e. banksel,
1877 * pic16_FixRegisterBanking: improved logic that causes the insertion
1879 * InlineFunction: functions that are called once, are not any more
1880 inlined. This can be a port option in the future,
1882 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
1884 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
1885 hold the corresponding uninitialized symbols,
1886 * pic16_allocProcessorRegister: registers have explicit marked the
1888 * pic16_allocInternalRegister: registers are explicit marked as
1890 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
1891 processing list, so bit registers were lost,
1894 * ralloc.h: added field 'accessBank' and original symbol operand
1895 in register definition,
1896 * removed the field isMapped from register definition,
1898 ** Several functions have been removed from various sources:
1899 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
1900 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
1901 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
1902 pic16_assignRelocatableRegisters
1904 ** others have been introduced:

1910 * support/scripts/inc2h.pl: changed definition of BIT_AT
1911 to emit 'sbit at' instead of 'bit at'. This was a request.
1913 PIC16 port related preliminary changes:
1914 * gen.c: prefixed function popRegFromString with
1915 pic16_ and all references to it corrected
1916 * pcode.c: all pic16_pc_* hardware registers prefixed
1917 with underscore (_),
1918 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
1919 * ralloc.c: newReg(): when register is REG_SFR then
1920 set address to rIdx,
1921 pic16_allocProcessorRegister(): marks register wasUsed=0
1922 pic16_writeUsedRegs(): added a call to assign processor
1923 registers via pic16_assignFixedRegisters
1925 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
1927 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
1928 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
1929 variables in unused register banks. Also the SSEG is placed
1930 wherever there is enough space for it, and IDATA can be anywhere
1931 in internal RAM. For now compile using -Wl-Y[stack_size].
1932 The mem file is different for this option as well, since it
1933 makes no sense of talking about DSEG lenght.
1935 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
1937 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2184 it breaks with bitfields, extern declarations, and gcse analysis.
2185 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2186 could be assigned through a pointer, so don't complain.

2929 * src/mcs51/gen.c (leftRightUseAcc),
2930 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
2931 iCode properly now. Use getSize instead of nRegs since a & b
2932 aren't part of the nRegs tally.
2934 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
2936 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

2942 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
2943 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
2944 fetching of the pointer
2945 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
2946 copied from genNearPointerSet()
2947 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
2948 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
2949 If they pop r0/r1 they must be called in the opposite order than aopOp().
2950 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
2951 (resp. --stack-auto), prepared for --xstack

2962 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
2964 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
2965 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
2966 type for bits was changed. It resulted in bit variables becoming
2967 global, which is not permitted in PIC 14 assembly output.
2969 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2971 * doc/sdccman.lyx: various additions and updates. Rearranged sections
2973 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2975 Z80 and MCS51 linkers complaint if a public symbol is defined
2976 in more than one library module:

2982 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2984 A few small changes that speed up the peephole optimizer.
2988 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2990 Try to make the peephole optimizer smarter by maintaining
2991 an association between the assembly source code and the
2992 iCodes that originated them. Put this information to use
2993 with a new peephole rule condition "notVolatile" so that
2994 the rules can be aggressive yet still safe.
2999 * src/mcs51/peeph.def
3001 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3005 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3006 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3007 if the left or right operand symbols have the accuse flag set.
3009 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3011 Changed the type of the result of the ! (NOT) operator to char;
3012 previously it returned the same type as the source. This allows
3013 us to eliminate all the genFloatNot functions (all of its target
3014 implementations were very buggy) since !float can use the same
3017 * src/SDCCicode.c (ast2iCode): ! returns char
3018 * src/mcs51/gen.c (genNot, genNotFloat),
3019 * src/ds390/gen.c (genNot, genNotFloat),
3020 * src/z80/gen.c (genNot, genNotFloat),
3021 * src/pic/gen.c (genNot, genNotFloat),
3022 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3024 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3026 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3027 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3028 during interrupts. Ensure WSAVE is located at a shared bank address.
3029 2. Fixed page selection in some places
3030 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3031 the registers name strings.
3032 4. Fixed "signed / unsigned compare" compiler warnings.
3033 5. The PIC port manages its own allocation of the general purpose
3034 registers, but makes no attempt to reuse them. As a result when
3035 compiling it soon runs out of general purpose registers. Some
3036 additional code was added to the files pcode.c and device.c to walk
3037 through the function call tree and rename the registers so that they
3047 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3048 genPlus() & genMinus() when the result is the same as left or right

3054 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3056 Made bitfield a distinct type from bit so that bitfields
3057 convert as per ANSI C and bits retain their traditional
3058 boolean style behaviour. Implemented bitfield support in
3066 * src/ds390/gen.c: bit v bitfield split
3067 * src/z80/gen.c: New support for bitfields
3068 * support/regression/tests/bitfields.c: reenabled z80,
3071 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3073 Rules 246.x, 247.x relate to bitfields, the others speed up
3074 access to xdata mapped I/O devices.
3076 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3078 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3080 Cleaned up genPackBits and genUnpackBits and added two helper
3081 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3082 for literal assignments in genPackBits (thanks to Frieder for
3088 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3090 Fixed bug #748310 (pointer to function type mishandled when the
3091 function name is omitted). Also fixed a SIGSEGV when a function
3092 attribute (reentrant, etc) is used on a non-function or on a
3093 function but misplaced before the parameter list.
3095 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3097 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3120 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3122 Made the constant following the "interrupt" keyword optional. If
3123 omitted, the function will not automatically be given an entry
3124 in the interrupt vector table (similar to #pragma NOIV, but
3125 less syntacticly kludgy). The interrupt number is also now
3126 range checked. Also fixed a bug in the high order bit example

3140 * src/SDCCicode.c (operandOperation): rewritten some ops
3141 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3142 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3144 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3145 be re-activated by defining REDUCE_LITERALS)
3146 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3147 unsigned, but are signed by default
3148 * src/SDCCval.c (constVal): rearranged
3149 * src/SDCCval.c (valMod): preliminary fix
3150 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3602 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3603 the regression tests I'm not brave enough to enable 245.b, 245.c
3604 * doc/sdccman.lyx: added latex preamble for hyperref package.
3605 Using pdflatex this will give you a hyperlinked pdf file with
3606 bookmarks. (prepend '%' before /usepackage if this breaks something)

3647 it can be defined with CFLAGS when running configure
3648 * src/SDCCmain.c: fixed compiling + linking with object files
3650 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

3653 added --disable-pic16-port
3654 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
3655 * src/SDCCmain.c: linkOptions is changed to set *,
3656 added if/endif conditional macros to remove options help
3657 messages from optionsTable when a port is not configured, added
3658 support for the PIc16 port in the ports table, when executing
3659 the compiler with no port specified on command line, a default
3660 port is selected with the new macro DEFAULT_PORT which is
3661 defined in port.h, in setDefaultOptions() linkOptions is removed
3662 from initialization assignment, since now it is a set,
3663 parseCmdLine uses setParseWithComma for linkOptions, in
3664 linkEdit() linkOptions are accessed with new function indexSet()
3665 which returns the i'th item of a set variable. See SDCCset.c, in
3666 linkEdit() when calling buildCmdLine(), added linkOptions as
3667 last argument. Now users can pass arguments to gplink via the
3668 -Wl option, main() uses pic16glue() to glue up pic16 programs

3680 * src/pic16/glue.c: commented out some error producing lines
3681 * src/pic16/main.c: __config directives are commented out to stop
3682 gpasm complaining and test the linkage with gplink, _linkCmd and
3683 _asmCmd changed to be more gplink and gpasm friendly
3684 * src/pic16/peeph.def: peep rule 3 is commented out, since it
3685 produced an error when parsed, peep rule 12 is added to utilize
3686 movff, but it is commented out since the pCode does not support
3687 yet a command with 2 address arguments
3689 2003-05-18 <johan AT balder>
3691 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
3692 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

3718 2003-05-11 Borut Razem <borut.razem AT siol.net>
3720 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
3721 the path of bin directory, so that PATH is the only env. variable, which has to be set
3722 in case of standard installation.

4819 overlaying area for it (uses RegBankUsed[4]).
4821 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
4822 bank zero as used by default. By default aslink locates the stack
4823 (equivalent to --stack-after-data). Pass option 'y' to aslink for
4824 the creation of the .mem file. Delegates the allocation of data area
4825 to aslink (it is not longer 0x30 by default). If --stack-loc passes
4826 the begining of the stack area to aslink.
4828 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
4829 glue() in SDCCglue.c creates an area for it.
4831 2002-09-03 Borut Razem <borut.razem AT siol.net>
4832 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
4833 sdcc/src/pic/glue.c:
4834 introduced atexit() handler for teporay files removal in case of
4835 errors, assertions, ...
4837 2002-08-29 Borut Razem <borut.razem AT siol.net>
4838 * sdcc/support/cpp2/auto-host_vc_in.h:
4839 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4840 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
4841 Maybe there is a similar problem with BORLANDC? It should be checked!
4843 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
4844 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4845 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
4846 was not executed, and the compiler (cl) launched a warning:
4847 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
4849 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
4850 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
4852 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
4853 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
4855 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4856 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
4857 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
4858 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4859 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
4860 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
4861 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
4862 - added Release configuration in VS projects
4863 - review of compiler an linker options
4864 - VC .exe files are generated in bin_vc directory, not to interfere
4865 with binaries generated from other projects (cygwin, mingw, bcc ...)
4867 * sdcc/src/yacc.dsp: added
4869 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
4870 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
4871 and insert the version number definitions from .version
4873 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
4875 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
4876 added - genarate auto-host.h using auto-host_vc_in.h as template
4879 removed from CVS, generated automatically
4881 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
4882 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
4884 2002-08-11 Borut Razem <borut.razem AT siol.net>
4885 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
4887 2002-08-10 Borut Razem <borut.razem AT siol.net>
4888 * src/SDCCmain.c (main):
4889 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
4890 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
4891 The consequence was that some temporary files were not removed.
4894 unification of code in functions tempfilename() and tempfile():
4895 function tempnam() is defined in Visual Studio 6.0 and .NET
4897 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
4899 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
4900 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
4901 - removed compiler command line option /WX: Treats all warnings as errors
4902 - update a list of source files, included into the project
4904 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
4905 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
4906 changed project type to Generic Project so that can be correcly converted to VS.NET project
4908 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
4910 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
4912 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
4914 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
4915 added return 0 statements after assert() to make compiler happy
4917 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
4918 added newline in the def file to keep MSC compiler satisfied
4920 * sdcc/src/z80/gen.c:
4921 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
4922 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
4923 - solved MSC error in function aopDump()
4925 * sdcc_vc.h: define PREFIX as "\\sdcc"
4927 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
4928 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

4976 Added -p option. Allows port dependent processor to be specified.
4979 Initialized the new field char *Processor field to NULL in all ports
4982 Compiler generated registers for interrupt context saving
4983 were not getting allocated.
4985 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
4988 Fixed left shift. Will promote the left side of a left shift
4989 if a) left shifting more than size of operand or b) when assigned
4990 to something size > size of left side
4992 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5100 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5102 * sdcc/src/SDCCloop.c:
5103 Previous fix was not good. basic blocks that have "break" or "return" are
5104 not really partof a loop , but live ranges used in these blocks should
5105 be live thru the entire loop, so set partOfLoop but don't add them to
5108 2002-02-21 <johan AT FRIJA>
5110 * src/SDCCcse.c: fixed bug #514308
5112 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5116 statement inside a loop, it was not being considered part of the loop.
5118 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5120 2002-02-10 Karl Bongers <karl AT turbobit.com>
5123 Fixed up SDCDB debugger somewhat. Updated debugger/README
5124 with lots of comments and notes.
5126 * device/examples/test2.c:
5127 Fix bug, "red" variable not being initialized(compiler complained).
