2456 loaded with the linker search paths (-L arguments) and the libraries
2457 to be linked with the current source (-l arguments). Changes
2458 currently will affect only the pic16 port.
2459 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2460 include path the port specific paths and port specific libraries,
2461 * gplink command now contains the $3 argument,

2479 Documenting changes from previous commits.
2480 * configure.in (version 1.56),
2481 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2482 when generating output files to configure the pic16 library,
2483 but now I've commented it out, since gputils aren't installed in the
2484 SF compile farm, so library won't compile
2486 * device/lib/Makefile.in (version 1.56): initially I've added in
2487 target 'all' the prerequestive 'model-pic16' so it compiled the
2488 pic16 library, but now I've commented it out for the same reasons
2490 * added targets 'model-pic16' and 'objects-pic16' to compile the
2492 * added target 'port-specific-objects-pic16' to handle the
2493 generated libraries and copy them into the build/ directory
2494 * added target 'clean-intermediate-pic16' to clean intermediate
2495 files into pic16 directory
2496 * in target 'installdirs' added line to create directory pic16 in

2500 added lines to copy all header files to installation path,
2501 * in target 'installdirs' added line create directory for pic16
2502 headers in the installation path

2782 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2783 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2784 * src/ds390/gen.c (genRightShift): fixed bug #870788
2785 * src/SDCCast.c (decorateType): fixed bug #870781
2787 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2789 PIC16 port related changes:
2790 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2791 added variable stackPos,
2793 * gen.c: genCall, assignResultValue: added support for
2794 pushing/retrieving function parameters to/from stack,
2795 genFunction,genEndFunction: setup stack frame for the
2797 genAddrOf: will be changed according to bug 863624
2799 * added files genutils.c and genutils.h which contain gen*
2800 debugged and optimised functions extracted from gen.c
2802 * glue.c: added variable 'externs' which holds extern symbols,
2803 pic16emitRegularMap: is modified to properly handle relocatable
2804 symbols under the new scheme,
2805 pic16createInterruptVect: is modified
2806 pic16printPublics: is modified to emit 'global' assembler directives,
2807 added pic16_printExterns to print extern symbols,
2808 pic16glue: initializes stack/frame pointer in the beginning of
2809 the assembly output. Temporary hack, will be corrected later,
2810 because gplink yet does not support stack and SDCC does not
2811 yet support a type of crt0.o object to create the final binary.
2813 * Removed many lines that contain 8051 legacy code.
2814 * The code is finally placed under a 'code' directive.
2815 * Added port specific options.
2817 * _process_pragma: simplified since now we do not need *special*
2818 include file to define SFR registers. But a separate header
2819 will be needed. This will be developed later.
2820 * _pic16_parseOptions: added, parses port specific options:
2821 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2822 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2823 --preplace-udata-with=
2825 * _pic16_setDefaultOptions: modified to initialize section names,
2826 but hack is temporarly out of order since it needs improvement.
2827 * _pic16_genAssemblerPreamble: configuration words are emitted by
2828 their address instead of their name. This part is incomplete and
2829 supports only the 18Fxx2 devices. Other devices will emit an error
2830 during assembly since they do not contain the same set of config
2832 * _pic16_genIVT: is modified,
2834 * pcode.c: added definitions for some hardware registers that are needed
2836 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2837 All PCI entries are updated. Now LFSR is supported.
2838 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2839 * added pic16_newpCodeOpLit2 to support instructions with
2840 two literal arguments
2841 * pic16_pCode2str: corrected code that emits assembler instructions
2842 with two literal operands and those that have an access bit modifier
2843 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2844 this fixes a bug which caused some labels to be lost, when an
2845 assembler directive was added, i.e. banksel,
2846 * pic16_FixRegisterBanking: improved logic that causes the insertion
2848 * InlineFunction: functions that are called once, are not any more
2849 inlined. This can be a port option in the future,
2851 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2853 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2854 hold the corresponding uninitialized symbols,
2855 * pic16_allocProcessorRegister: registers have explicit marked the
2857 * pic16_allocInternalRegister: registers are explicit marked as
2859 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2860 processing list, so bit registers were lost,
2863 * ralloc.h: added field 'accessBank' and original symbol operand
2864 in register definition,
2865 * removed the field isMapped from register definition,
2867 ** Several functions have been removed from various sources:
2868 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2869 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2870 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2871 pic16_assignRelocatableRegisters
2873 ** others have been introduced:
2874 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2875 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2877 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2879 * support/scripts/inc2h.pl: changed definition of BIT_AT
2880 to emit 'sbit at' instead of 'bit at'. This was a request.
2882 PIC16 port related preliminary changes:
2883 * gen.c: prefixed function popRegFromString with
2884 pic16_ and all references to it corrected
2885 * pcode.c: all pic16_pc_* hardware registers prefixed
2886 with underscore (_),
2887 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2888 * ralloc.c: newReg(): when register is REG_SFR then
2889 set address to rIdx,
2890 pic16_allocProcessorRegister(): marks register wasUsed=0
2891 pic16_writeUsedRegs(): added a call to assign processor
2892 registers via pic16_assignFixedRegisters
2894 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2896 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2897 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2898 variables in unused register banks. Also the SSEG is placed
2899 wherever there is enough space for it, and IDATA can be anywhere
2900 in internal RAM. For now compile using -Wl-Y[stack_size].
2901 The mem file is different for this option as well, since it
2902 makes no sense of talking about DSEG lenght.
2904 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2906 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2907 in certain cases, e.g. when ROM assignment, patch provided
2908 from Albert den Haan.
2910 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3149 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3151 * src/SDCCast.c (decorateType): disabled a transformation I added in
3152 revision 1.188 (access to fields of a structure at an absolute address);
3153 it breaks with bitfields, extern declarations, and gcse analysis.
3154 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3155 could be assigned through a pointer, so don't complain.
3156 * src/SDCCast.c (astErrors),
3158 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

3796 support for standard C idiom of memory mapped variables; for
3797 example, *((xdata int*)0x1234) = 1 is now internally equivalent
3798 to xdata int at 0x1234 tempvar = 1.
3799 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
3800 provided by Akiya ISHIDA

3816 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3818 Fixed bug #621531 (const & volatile confusion in the type chain).
3819 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

3911 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3912 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3913 fetching of the pointer
3914 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3915 copied from genNearPointerSet()
3916 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3917 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3933 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3934 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3935 type for bits was changed. It resulted in bit variables becoming
3936 global, which is not permitted in PIC 14 assembly output.
3938 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3940 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3953 A few small changes that speed up the peephole optimizer.
3957 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3959 Try to make the peephole optimizer smarter by maintaining
3960 an association between the assembly source code and the
3961 iCodes that originated them. Put this information to use
3962 with a new peephole rule condition "notVolatile" so that
3963 the rules can be aggressive yet still safe.
3968 * src/mcs51/peeph.def
3970 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3974 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3975 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3976 if the left or right operand symbols have the accuse flag set.
3978 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3980 Changed the type of the result of the ! (NOT) operator to char;
3981 previously it returned the same type as the source. This allows
3982 us to eliminate all the genFloatNot functions (all of its target
3983 implementations were very buggy) since !float can use the same
3986 * src/SDCCicode.c (ast2iCode): ! returns char

3995 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3996 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3997 during interrupts. Ensure WSAVE is located at a shared bank address.
3998 2. Fixed page selection in some places
3999 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4000 the registers name strings.
4001 4. Fixed "signed / unsigned compare" compiler warnings.
4002 5. The PIC port manages its own allocation of the general purpose
4003 registers, but makes no attempt to reuse them. As a result when
4004 compiling it soon runs out of general purpose registers. Some
4005 additional code was added to the files pcode.c and device.c to walk
4006 through the function call tree and rename the registers so that they
4016 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4017 genPlus() & genMinus() when the result is the same as left or right

4023 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4025 Made bitfield a distinct type from bit so that bitfields
4026 convert as per ANSI C and bits retain their traditional
4027 boolean style behaviour. Implemented bitfield support in
4035 * src/ds390/gen.c: bit v bitfield split
4036 * src/z80/gen.c: New support for bitfields
4037 * support/regression/tests/bitfields.c: reenabled z80,
4040 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4042 Rules 246.x, 247.x relate to bitfields, the others speed up
4043 access to xdata mapped I/O devices.
4045 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4047 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4049 Cleaned up genPackBits and genUnpackBits and added two helper
4050 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4051 for literal assignments in genPackBits (thanks to Frieder for
4057 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4059 Fixed bug #748310 (pointer to function type mishandled when the
4060 function name is omitted). Also fixed a SIGSEGV when a function
4061 attribute (reentrant, etc) is used on a non-function or on a
4062 function but misplaced before the parameter list.
4064 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4066 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4067 * support/Util/SDCCerr.h,
4068 * support/Util/SDCCerr.c: Added func attr misuse error msg

4089 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4091 Made the constant following the "interrupt" keyword optional. If
4092 omitted, the function will not automatically be given an entry
4093 in the interrupt vector table (similar to #pragma NOIV, but
4094 less syntacticly kludgy). The interrupt number is also now
4095 range checked. Also fixed a bug in the high order bit example

4109 * src/SDCCicode.c (operandOperation): rewritten some ops
4110 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4111 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4113 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4114 be re-activated by defining REDUCE_LITERALS)
4115 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4116 unsigned, but are signed by default
4117 * src/SDCCval.c (constVal): rearranged
4118 * src/SDCCval.c (valMod): preliminary fix
4119 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4161 constants are unsigned; added recognition of "u" flag for unsigned
4162 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4163 * src/SDCCval.c (valDiv, valMod): fixed signdness
4164 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4165 signedness of modulo, left and right shift

4624 * src/SDCCmain.c: linkOptions is changed to set *,
4625 added if/endif conditional macros to remove options help
4626 messages from optionsTable when a port is not configured, added
4627 support for the PIc16 port in the ports table, when executing
4628 the compiler with no port specified on command line, a default
4629 port is selected with the new macro DEFAULT_PORT which is
4630 defined in port.h, in setDefaultOptions() linkOptions is removed
4631 from initialization assignment, since now it is a set,
4632 parseCmdLine uses setParseWithComma for linkOptions, in
4633 linkEdit() linkOptions are accessed with new function indexSet()
4634 which returns the i'th item of a set variable. See SDCCset.c, in
4635 linkEdit() when calling buildCmdLine(), added linkOptions as
4636 last argument. Now users can pass arguments to gplink via the
4637 -Wl option, main() uses pic16glue() to glue up pic16 programs

4650 * src/pic16/main.c: __config directives are commented out to stop
4651 gpasm complaining and test the linkage with gplink, _linkCmd and
4652 _asmCmd changed to be more gplink and gpasm friendly
4653 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4654 produced an error when parsed, peep rule 12 is added to utilize
4655 movff, but it is commented out since the pCode does not support
4656 yet a command with 2 address arguments
4658 2003-05-18 <johan AT balder>
4660 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4687 2003-05-11 Borut Razem <borut.razem AT siol.net>
4689 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4690 the path of bin directory, so that PATH is the only env. variable, which has to be set

5706 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
5708 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5709 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
5710 * support/regression/tests/bug-524697.c: fit mem usage into 8032
5712 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
5713 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
5715 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
5716 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
5718 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
5719 * src/mcs51/main.c: removed {bindir}{sep} from aslink
5721 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5723 * in \sdcc\as\mcs51\ changed these files in order to create an
5724 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5725 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5726 following files to include the previous two files: aslink.dsp,
5727 Makefile.aslink, Makefile.bcc, and Makefile.in.
5729 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5730 .adb instead of .cdb
5732 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5734 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5735 value from option --iram-size.
5737 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5739 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5742 2002-09-18 <wiml AT hhhh.org>
5744 * SDCClrange.h: exposed setFromRange() and setToRange()
5745 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5746 packRegsForAccUse() (bug 542397)
5747 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5748 multiple times and emitting the fetch operations more than once
5749 added aopGetUsesAcc() function to allow binary operators to
5750 fetch their operands in the correct order; made genMinus() emit
5751 compact code for X = LITERAL - Y
5753 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5754 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5755 sprintf() in line 1267.
5757 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5758 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5761 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5762 Changes to aslink (All the changes are marked with 'JCF'):
5764 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5767 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5768 area BSEG. Also moves, if possible, the DATA area down into the internal
5769 ram so more space is available.
5771 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5774 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5775 not bytes. Function summary() which creates a memory usage summary
5776 file with extension .mem. Reports of overlaping stack and small stack
5777 size. If the space for the stack is less than 16 bytes aslink trows a
5780 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5781 the 8051. Option 'y' for memory summary output file.
5783 Changes to sdcc (All the changes are marked with 'JCF'):
5785 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5787 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5788 overlaying area for it (uses RegBankUsed[4]).
5790 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5791 bank zero as used by default. By default aslink locates the stack
5792 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5793 the creation of the .mem file. Delegates the allocation of data area
5794 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5795 the begining of the stack area to aslink.
5797 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5798 glue() in SDCCglue.c creates an area for it.
5800 2002-09-03 Borut Razem <borut.razem AT siol.net>
5801 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5802 sdcc/src/pic/glue.c:
5803 introduced atexit() handler for teporay files removal in case of
5804 errors, assertions, ...
5806 2002-08-29 Borut Razem <borut.razem AT siol.net>
5807 * sdcc/support/cpp2/auto-host_vc_in.h:
5808 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5809 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5810 Maybe there is a similar problem with BORLANDC? It should be checked!
5812 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5813 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5814 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5815 was not executed, and the compiler (cl) launched a warning:
5816 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5818 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5819 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5821 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5822 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5824 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5825 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5826 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5827 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5828 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5829 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5830 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5831 - added Release configuration in VS projects
5832 - review of compiler an linker options
5833 - VC .exe files are generated in bin_vc directory, not to interfere
5834 with binaries generated from other projects (cygwin, mingw, bcc ...)
5836 * sdcc/src/yacc.dsp: added
5838 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5839 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5840 and insert the version number definitions from .version
5842 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5844 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5845 added - genarate auto-host.h using auto-host_vc_in.h as template
5848 removed from CVS, generated automatically
5850 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5851 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5853 2002-08-11 Borut Razem <borut.razem AT siol.net>
5854 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5856 2002-08-10 Borut Razem <borut.razem AT siol.net>
5857 * src/SDCCmain.c (main):
5858 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5859 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5860 The consequence was that some temporary files were not removed.
5863 unification of code in functions tempfilename() and tempfile():
5864 function tempnam() is defined in Visual Studio 6.0 and .NET
5866 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5868 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5869 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5870 - removed compiler command line option /WX: Treats all warnings as errors
5871 - update a list of source files, included into the project
5873 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5874 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5875 changed project type to Generic Project so that can be correcly converted to VS.NET project
5877 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5879 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5881 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5883 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5884 added return 0 statements after assert() to make compiler happy
5886 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5887 added newline in the def file to keep MSC compiler satisfied
5889 * sdcc/src/z80/gen.c:
5890 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5891 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5892 - solved MSC error in function aopDump()
5894 * sdcc_vc.h: define PREFIX as "\\sdcc"
5896 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5897 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5936 2002-03-28 Johan Knol <johan AT balder>
5938 * src/SDCCval.c: fixed bug #532436
5940 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5942 Added "char *Processor" field to the port structure.
5945 Added -p option. Allows port dependent processor to be specified.
5948 Initialized the new field char *Processor field to NULL in all ports
5951 Compiler generated registers for interrupt context saving
5952 were not getting allocated.
5954 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5957 Fixed left shift. Will promote the left side of a left shift
5958 if a) left shifting more than size of operand or b) when assigned
5959 to something size > size of left side
5961 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5963 tons of changes. Register allocation has been
5964 rewritten. Added customization for the various PICs. Flow

6069 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6071 * sdcc/src/SDCCloop.c:
6072 Previous fix was not good. basic blocks that have "break" or "return" are
6073 not really partof a loop , but live ranges used in these blocks should
6074 be live thru the entire loop, so set partOfLoop but don't add them to
6077 2002-02-21 <johan AT FRIJA>
6079 * src/SDCCcse.c: fixed bug #514308
6081 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6084 Fixed BUG #519583. If a conditional block ended in a return/break
6085 statement inside a loop, it was not being considered part of the loop.
6087 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6089 2002-02-10 Karl Bongers <karl AT turbobit.com>
6092 Fixed up SDCDB debugger somewhat. Updated debugger/README
6093 with lots of comments and notes.
6095 * device/examples/test2.c:
6096 Fix bug, "red" variable not being initialized(compiler complained).
6098 * device/examples/Makefile, examples/test3.c:

6100 for use as a multiple module SDCDB test case.
6102 * sim/ucsim/cmd.src/cmdset.cc:
6103 Took out debug printfs in ucsim "next" command.
6106 Karl and Johan start ucsim XA support. Most dissassembly working,
6107 about 75% emulation done(plenty of work remaining).
6109 * sim/ucsim/z80.src:
6110 Add Z80 support to ucsim, add test-ucz80 regression test,
6111 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

6147 set preprocessor defines (depending on options)
6149 * src/SDCCicode.c, src/SDCCicode.h:
6150 changes made to handle multiple sends & receives
6153 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
