379 Adding support for replacing ljmps with sjmps in jumptables
380 generated for switch statements. For now you need to set the
381 environment variable SDCC_SJMP_JUMPTABLE to enable this.
382 Now 4 algorithms for mcs51 jumptable generation are used:
383 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

413 to call when a stack overflow occurs,
414 * (malloc.h): added CVS Id tag,
415 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
417 * added libc directory. The current version of LibC contains string
418 functions, ctype functions and macros and some functions of the
419 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
420 be extensively tested in the future. Standard disclaimer here.
421 Library is not automatically build yet. But one can build it by
422 invoking 'make' inside the libc directory.
423 * added ADC library under libio. Preliminary version yet.

432 * (genUminusFloat): fixed for pic16, ported code from mcs51,
433 * (pic16_storeForReturn): optimized return of 0,
434 * (genCmp): experimental code for new genCmp which uses PIC18's
435 special compare&skip instructions. Initial tests fail some times
436 with variables grater than 1 byte in size, so new code is disabled,
437 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
439 * (genCast): began a fix to optimize the casting of a bit to another
440 bit, now assigning a bitfield to another bitfield will fail, sorry,
441 * src/pic16/main.c: disabled the use of lr-support feature,
442 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3463 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3465 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3466 loaded with the linker search paths (-L arguments) and the libraries
3467 to be linked with the current source (-l arguments). Changes
3468 currently will affect only the pic16 port.
3469 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3470 include path the port specific paths and port specific libraries,
3471 * gplink command now contains the $3 argument,
3472 * src/pic16/device.h,
3473 * src/pic16/device.c,: structure PIC_device is made public and
3474 renamed to PIC16_device, the same for variable Pics which is renamed

3489 Documenting changes from previous commits.
3490 * configure.in (version 1.56),
3491 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3492 when generating output files to configure the pic16 library,
3493 but now I've commented it out, since gputils aren't installed in the
3494 SF compile farm, so library won't compile
3496 * device/lib/Makefile.in (version 1.56): initially I've added in
3497 target 'all' the prerequestive 'model-pic16' so it compiled the
3498 pic16 library, but now I've commented it out for the same reasons
3500 * added targets 'model-pic16' and 'objects-pic16' to compile the
3502 * added target 'port-specific-objects-pic16' to handle the
3503 generated libraries and copy them into the build/ directory
3504 * added target 'clean-intermediate-pic16' to clean intermediate
3505 files into pic16 directory
3506 * in target 'installdirs' added line to create directory pic16 in
3507 the installation path

3510 added lines to copy all header files to installation path,
3511 * in target 'installdirs' added line create directory for pic16
3512 headers in the installation path

3528 option so that it actually works. Made it specific to the z80, since
3529 the gbz80 doesn't have these kinds of I/O ports.
3531 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3533 * device/include/z180.h,

3557 via literal number. The symbol is placed in the corresponding
3558 position of the data ram
3559 * (pic16_dump_section): relocatable and absolute uninitialized
3560 data are now emitted in sorted order to reduce section naming,
3561 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3562 weren't marked as being in the access bank,
3564 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3566 Added portion of GNU PIC Library under the directory
3567 device/include/pic16 and device/lib/pic16. These files
3568 contain the declarations of SFRs for the PIC18Fxx2 devices.
3569 The directory is initialized via configure from toplevel.

3580 2004-01-12 Borut Razem <borut.razem AT siol.net>
3582 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
3583 doc/sdccman.lyx: upper case pragmas are deprecated
3585 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

3598 * doc/sdccman.lyx: Moved and added some sections, small changes
3599 all over. Telling LaTeX to be less strict with word spacing
3600 to better keep the right margin. Changed some notes about
3601 maintainance of the ports in section 3.2.1 - is it OK like this?
3603 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3605 SDCC source changes:
3606 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3640 UPPER for immediate operands,
3641 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3643 * src/pic16/peeph.def: all peepholes with movff are commented out,
3644 because there is a problem in the pcode peep optimizer,
3645 * src/pic16/ralloc.c: the register allocator can now reuse local

3738 include information about variables allocated to the overlay
3741 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3743 * as/mcs51/lkmain.c: Help about -Y option

3755 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3757 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3758 (default behaviour).
3760 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3762 A python script to validate compiler diagnostic messages. It can be
3763 used to verify that sdcc complains about bad c source code and
3764 gives a good location of the error.
3765 * support/valdiag/Makefile,
3766 * support/valdiag/valdiag.py,
3767 * support/valdiag/tests/*

3783 around the header file.
3784 Bug reported from Jesus Calvino-Fraga
3786 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3788 * sdcc.spec: updated
3789 * device/include/Makefile.in: don't install CVS directories
3790 * device/lib/Makefile.in: added removal of CVS directories after install
3791 * doc/Makefile: fixed install, added local_icons
3792 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3793 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3794 * src/ds390/gen.c (genRightShift): fixed bug #870788
3795 * src/SDCCast.c (decorateType): fixed bug #870781
3797 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3799 PIC16 port related changes:
3800 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3801 added variable stackPos,
3803 * gen.c: genCall, assignResultValue: added support for
3804 pushing/retrieving function parameters to/from stack,
3805 genFunction,genEndFunction: setup stack frame for the
3807 genAddrOf: will be changed according to bug 863624
3809 * added files genutils.c and genutils.h which contain gen*
3810 debugged and optimised functions extracted from gen.c
3812 * glue.c: added variable 'externs' which holds extern symbols,
3813 pic16emitRegularMap: is modified to properly handle relocatable
3814 symbols under the new scheme,
3815 pic16createInterruptVect: is modified
3816 pic16printPublics: is modified to emit 'global' assembler directives,
3817 added pic16_printExterns to print extern symbols,
3818 pic16glue: initializes stack/frame pointer in the beginning of
3819 the assembly output. Temporary hack, will be corrected later,
3820 because gplink yet does not support stack and SDCC does not
3821 yet support a type of crt0.o object to create the final binary.
3823 * Removed many lines that contain 8051 legacy code.
3824 * The code is finally placed under a 'code' directive.
3825 * Added port specific options.
3827 * _process_pragma: simplified since now we do not need *special*
3828 include file to define SFR registers. But a separate header
3829 will be needed. This will be developed later.
3830 * _pic16_parseOptions: added, parses port specific options:
3831 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3832 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3833 --preplace-udata-with=
3835 * _pic16_setDefaultOptions: modified to initialize section names,
3836 but hack is temporarly out of order since it needs improvement.
3837 * _pic16_genAssemblerPreamble: configuration words are emitted by
3838 their address instead of their name. This part is incomplete and
3839 supports only the 18Fxx2 devices. Other devices will emit an error
3840 during assembly since they do not contain the same set of config
3842 * _pic16_genIVT: is modified,
3844 * pcode.c: added definitions for some hardware registers that are needed
3846 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3847 All PCI entries are updated. Now LFSR is supported.
3848 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3849 * added pic16_newpCodeOpLit2 to support instructions with
3850 two literal arguments
3851 * pic16_pCode2str: corrected code that emits assembler instructions
3852 with two literal operands and those that have an access bit modifier
3853 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3854 this fixes a bug which caused some labels to be lost, when an
3855 assembler directive was added, i.e. banksel,
3856 * pic16_FixRegisterBanking: improved logic that causes the insertion
3858 * InlineFunction: functions that are called once, are not any more
3859 inlined. This can be a port option in the future,
3861 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3863 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3864 hold the corresponding uninitialized symbols,
3865 * pic16_allocProcessorRegister: registers have explicit marked the
3867 * pic16_allocInternalRegister: registers are explicit marked as
3869 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3870 processing list, so bit registers were lost,
3873 * ralloc.h: added field 'accessBank' and original symbol operand
3874 in register definition,
3875 * removed the field isMapped from register definition,
3877 ** Several functions have been removed from various sources:
3878 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3879 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3880 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3881 pic16_assignRelocatableRegisters
3883 ** others have been introduced:
3884 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3885 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3887 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3889 * support/scripts/inc2h.pl: changed definition of BIT_AT
3890 to emit 'sbit at' instead of 'bit at'. This was a request.
3892 PIC16 port related preliminary changes:
3893 * gen.c: prefixed function popRegFromString with
3894 pic16_ and all references to it corrected
3895 * pcode.c: all pic16_pc_* hardware registers prefixed
3896 with underscore (_),
3897 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3898 * ralloc.c: newReg(): when register is REG_SFR then
3899 set address to rIdx,
3900 pic16_allocProcessorRegister(): marks register wasUsed=0
3901 pic16_writeUsedRegs(): added a call to assign processor
3902 registers via pic16_assignFixedRegisters
3904 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3906 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3907 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3908 variables in unused register banks. Also the SSEG is placed
3909 wherever there is enough space for it, and IDATA can be anywhere
3910 in internal RAM. For now compile using -Wl-Y[stack_size].
3911 The mem file is different for this option as well, since it
3912 makes no sense of talking about DSEG lenght.
3914 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3916 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3917 in certain cases, e.g. when ROM assignment, patch provided
3918 from Albert den Haan.
3920 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4063 * src/mcs51/peephole.def,
4064 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4943 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4944 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4945 type for bits was changed. It resulted in bit variables becoming

4963 A few small changes that speed up the peephole optimizer.
4967 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4969 Try to make the peephole optimizer smarter by maintaining
4970 an association between the assembly source code and the
4971 iCodes that originated them. Put this information to use
4972 with a new peephole rule condition "notVolatile" so that
4973 the rules can be aggressive yet still safe.
4978 * src/mcs51/peeph.def
4980 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4984 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4985 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4986 if the left or right operand symbols have the accuse flag set.
4988 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4990 Changed the type of the result of the ! (NOT) operator to char;
4991 previously it returned the same type as the source. This allows
4992 us to eliminate all the genFloatNot functions (all of its target
4993 implementations were very buggy) since !float can use the same
4996 * src/SDCCicode.c (ast2iCode): ! returns char

5005 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5006 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5007 during interrupts. Ensure WSAVE is located at a shared bank address.
5008 2. Fixed page selection in some places
5009 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5010 the registers name strings.
5011 4. Fixed "signed / unsigned compare" compiler warnings.
5012 5. The PIC port manages its own allocation of the general purpose
5013 registers, but makes no attempt to reuse them. As a result when
5014 compiling it soon runs out of general purpose registers. Some
5015 additional code was added to the files pcode.c and device.c to walk
5016 through the function call tree and rename the registers so that they
5026 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5033 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5035 Made bitfield a distinct type from bit so that bitfields
5036 convert as per ANSI C and bits retain their traditional
5037 boolean style behaviour. Implemented bitfield support in
5045 * src/ds390/gen.c: bit v bitfield split
5046 * src/z80/gen.c: New support for bitfields
5047 * support/regression/tests/bitfields.c: reenabled z80,
5050 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5052 Rules 246.x, 247.x relate to bitfields, the others speed up
5053 access to xdata mapped I/O devices.
5055 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5057 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5059 Cleaned up genPackBits and genUnpackBits and added two helper

5069 Fixed bug #748310 (pointer to function type mishandled when the
5070 function name is omitted). Also fixed a SIGSEGV when a function
5071 attribute (reentrant, etc) is used on a non-function or on a
5072 function but misplaced before the parameter list.

5101 Made the constant following the "interrupt" keyword optional. If
5102 omitted, the function will not automatically be given an entry
5103 in the interrupt vector table (similar to #pragma NOIV, but
5104 less syntacticly kludgy). The interrupt number is also now
5105 range checked. Also fixed a bug in the high order bit example
5112 * support/Util/SDCCerr.c
5113 * support/Util/SDCCerr.h
5116 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5126 unsigned, but are signed by default
5127 * src/SDCCval.c (constVal): rearranged
5128 * src/SDCCval.c (valMod): preliminary fix
5129 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5172 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5173 * src/SDCCval.c (valDiv, valMod): fixed signdness
5174 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5175 signedness of modulo, left and right shift
5176 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

5638 the compiler with no port specified on command line, a default
5639 port is selected with the new macro DEFAULT_PORT which is
5640 defined in port.h, in setDefaultOptions() linkOptions is removed
5641 from initialization assignment, since now it is a set,
5642 parseCmdLine uses setParseWithComma for linkOptions, in
5643 linkEdit() linkOptions are accessed with new function indexSet()
5644 which returns the i'th item of a set variable. See SDCCset.c, in

6709 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6711 2003-01-04 <johan AT balder>
6713 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6715 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6716 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6718 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6719 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6726 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6728 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6729 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6731 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6733 * in \sdcc\as\mcs51\ changed these files in order to create an
6734 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6735 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6736 following files to include the previous two files: aslink.dsp,
6737 Makefile.aslink, Makefile.bcc, and Makefile.in.
6739 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6740 .adb instead of .cdb
6742 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6744 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6745 value from option --iram-size.
6747 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6749 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6752 2002-09-18 <wiml AT hhhh.org>
6754 * SDCClrange.h: exposed setFromRange() and setToRange()
6755 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6756 packRegsForAccUse() (bug 542397)
6757 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6758 multiple times and emitting the fetch operations more than once
6759 added aopGetUsesAcc() function to allow binary operators to
6760 fetch their operands in the correct order; made genMinus() emit
6761 compact code for X = LITERAL - Y
6763 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6764 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6765 sprintf() in line 1267.
6767 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6768 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6771 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6772 Changes to aslink (All the changes are marked with 'JCF'):
6774 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6777 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6778 area BSEG. Also moves, if possible, the DATA area down into the internal
6779 ram so more space is available.
6781 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6784 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6785 not bytes. Function summary() which creates a memory usage summary
6786 file with extension .mem. Reports of overlaping stack and small stack
6787 size. If the space for the stack is less than 16 bytes aslink trows a
6790 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6791 the 8051. Option 'y' for memory summary output file.
6793 Changes to sdcc (All the changes are marked with 'JCF'):
6795 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6797 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6798 overlaying area for it (uses RegBankUsed[4]).
6800 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6801 bank zero as used by default. By default aslink locates the stack
6802 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6803 the creation of the .mem file. Delegates the allocation of data area
6804 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6805 the begining of the stack area to aslink.
6807 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6808 glue() in SDCCglue.c creates an area for it.
6810 2002-09-03 Borut Razem <borut.razem AT siol.net>
6811 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6812 sdcc/src/pic/glue.c:
6813 introduced atexit() handler for teporay files removal in case of
6814 errors, assertions, ...
6816 2002-08-29 Borut Razem <borut.razem AT siol.net>
6817 * sdcc/support/cpp2/auto-host_vc_in.h:
6818 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6819 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6820 Maybe there is a similar problem with BORLANDC? It should be checked!
6822 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6823 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6824 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6825 was not executed, and the compiler (cl) launched a warning:
6826 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6828 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6829 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6831 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6832 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6834 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6835 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6836 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6837 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6838 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6839 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6840 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6841 - added Release configuration in VS projects
6842 - review of compiler an linker options
6843 - VC .exe files are generated in bin_vc directory, not to interfere
6844 with binaries generated from other projects (cygwin, mingw, bcc ...)
6846 * sdcc/src/yacc.dsp: added
6848 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6849 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6850 and insert the version number definitions from .version
6852 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6854 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6855 added - genarate auto-host.h using auto-host_vc_in.h as template
6858 removed from CVS, generated automatically
6860 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6861 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6863 2002-08-11 Borut Razem <borut.razem AT siol.net>
6864 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6866 2002-08-10 Borut Razem <borut.razem AT siol.net>
6867 * src/SDCCmain.c (main):
6868 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6869 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6870 The consequence was that some temporary files were not removed.
6873 unification of code in functions tempfilename() and tempfile():
6874 function tempnam() is defined in Visual Studio 6.0 and .NET
6876 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6878 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6879 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6880 - removed compiler command line option /WX: Treats all warnings as errors
6881 - update a list of source files, included into the project
6883 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6884 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6885 changed project type to Generic Project so that can be correcly converted to VS.NET project
6887 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6889 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6891 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6893 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6894 added return 0 statements after assert() to make compiler happy
6896 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6897 added newline in the def file to keep MSC compiler satisfied
6899 * sdcc/src/z80/gen.c:
6900 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6901 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6902 - solved MSC error in function aopDump()
6904 * sdcc_vc.h: define PREFIX as "\\sdcc"
6906 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6907 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6909 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6910 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6911 - Rewrote the register banking algorithm.
6912 - Added pCode live-range analysis to registers (for now, only non-used and
6913 singly-used registers optimized away)
6915 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6917 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
6919 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6920 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6922 2002-04-22 Michael Hope <michaelh AT vroom>

6938 * src/z80/peeph.def: Added transpose redundent load rule.
6940 * src/z80/main.c: Added force callee saves for jaune.
6942 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6944 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6946 2002-03-28 Johan Knol <johan AT balder>
6948 * src/SDCCval.c: fixed bug #532436
6950 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6952 Added "char *Processor" field to the port structure.
6955 Added -p option. Allows port dependent processor to be specified.
6958 Initialized the new field char *Processor field to NULL in all ports
6961 Compiler generated registers for interrupt context saving
6962 were not getting allocated.
6964 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6967 Fixed left shift. Will promote the left side of a left shift
6968 if a) left shifting more than size of operand or b) when assigned
6969 to something size > size of left side
6971 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6973 tons of changes. Register allocation has been
6974 rewritten. Added customization for the various PICs. Flow
6975 analysis is restructured. ...
6981 Added. device.c is a PIC port hack to accomodate variations
6984 2002-03-13 Michael Hope <michaelh AT vroom>
6986 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6988 2002-03-04 johanknol <johanknol AT manik>
6990 * /src/SDCCval.c: fixed
6992 const unsigned char arr[][2] = { { 0, 1 } };
6993 t18.c:1: error: Initializer element is not constant
6995 2002-03-04 bela <bela AT manik>
6997 * /device/include/mcs51reg.h:
