395 Adding support for replacing ljmps with sjmps in jumptables
396 generated for switch statements. For now you need to set the
397 environment variable SDCC_SJMP_JUMPTABLE to enable this.
398 Now 4 algorithms for mcs51 jumptable generation are used:
399 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
400 addresses loaded pc-relative for up to 112 cases and stack-pushing
401 target addresses loaded with offset from dptr for up to 256 cases.

428 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
429 to call when a stack overflow occurs,
430 * (malloc.h): added CVS Id tag,
431 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
433 * added libc directory. The current version of LibC contains string
434 functions, ctype functions and macros and some functions of the
435 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
436 be extensively tested in the future. Standard disclaimer here.
437 Library is not automatically build yet. But one can build it by
438 invoking 'make' inside the libc directory.
439 * added ADC library under libio. Preliminary version yet.
441 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

447 * (pic16_outBitC): fixed for results in size greater than 1,
448 * (genUminusFloat): fixed for pic16, ported code from mcs51,
449 * (pic16_storeForReturn): optimized return of 0,
450 * (genCmp): experimental code for new genCmp which uses PIC18's
451 special compare&skip instructions. Initial tests fail some times

3479 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3481 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3482 loaded with the linker search paths (-L arguments) and the libraries
3483 to be linked with the current source (-l arguments). Changes
3484 currently will affect only the pic16 port.
3485 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3486 include path the port specific paths and port specific libraries,
3487 * gplink command now contains the $3 argument,
3488 * src/pic16/device.h,
3489 * src/pic16/device.c,: structure PIC_device is made public and
3490 renamed to PIC16_device, the same for variable Pics which is renamed

3505 Documenting changes from previous commits.
3506 * configure.in (version 1.56),
3507 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3508 when generating output files to configure the pic16 library,
3509 but now I've commented it out, since gputils aren't installed in the
3510 SF compile farm, so library won't compile
3512 * device/lib/Makefile.in (version 1.56): initially I've added in
3513 target 'all' the prerequestive 'model-pic16' so it compiled the
3514 pic16 library, but now I've commented it out for the same reasons
3516 * added targets 'model-pic16' and 'objects-pic16' to compile the
3518 * added target 'port-specific-objects-pic16' to handle the
3519 generated libraries and copy them into the build/ directory
3520 * added target 'clean-intermediate-pic16' to clean intermediate
3521 files into pic16 directory
3522 * in target 'installdirs' added line to create directory pic16 in
3523 the installation path
3525 * device/include/Makefile.in (version 1.11): in target 'install'
3526 added lines to copy all header files to installation path,
3527 * in target 'installdirs' added line create directory for pic16
3528 headers in the installation path

3543 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3544 option so that it actually works. Made it specific to the z80, since
3545 the gbz80 doesn't have these kinds of I/O ports.
3547 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3549 * device/include/z180.h,

3573 via literal number. The symbol is placed in the corresponding
3574 position of the data ram
3575 * (pic16_dump_section): relocatable and absolute uninitialized
3576 data are now emitted in sorted order to reduce section naming,
3577 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3578 weren't marked as being in the access bank,
3580 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3582 Added portion of GNU PIC Library under the directory
3583 device/include/pic16 and device/lib/pic16. These files
3584 contain the declarations of SFRs for the PIC18Fxx2 devices.
3585 The directory is initialized via configure from toplevel.
3587 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3614 * doc/sdccman.lyx: Moved and added some sections, small changes
3615 all over. Telling LaTeX to be less strict with word spacing
3616 to better keep the right margin. Changed some notes about
3617 maintainance of the ports in section 3.2.1 - is it OK like this?
3619 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3621 SDCC source changes:
3622 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3657 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3659 * src/pic16/peeph.def: all peepholes with movff are commented out,
3660 because there is a problem in the pcode peep optimizer,
3661 * src/pic16/ralloc.c: the register allocator can now reuse local

3754 include information about variables allocated to the overlay
3757 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3759 * as/mcs51/lkmain.c: Help about -Y option

3771 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3773 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3774 (default behaviour).
3776 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3778 A python script to validate compiler diagnostic messages. It can be
3779 used to verify that sdcc complains about bad c source code and
3780 gives a good location of the error.
3781 * support/valdiag/Makefile,
3782 * support/valdiag/valdiag.py,
3783 * support/valdiag/tests/*
3785 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3798 * src/common.h: added ifndef/define/endif macros
3799 around the header file.
3800 Bug reported from Jesus Calvino-Fraga
3802 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3804 * sdcc.spec: updated
3805 * device/include/Makefile.in: don't install CVS directories
3806 * device/lib/Makefile.in: added removal of CVS directories after install
3807 * doc/Makefile: fixed install, added local_icons
3808 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3809 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3810 * src/ds390/gen.c (genRightShift): fixed bug #870788
3811 * src/SDCCast.c (decorateType): fixed bug #870781
3813 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3815 PIC16 port related changes:
3816 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3817 added variable stackPos,
3819 * gen.c: genCall, assignResultValue: added support for
3820 pushing/retrieving function parameters to/from stack,
3821 genFunction,genEndFunction: setup stack frame for the
3823 genAddrOf: will be changed according to bug 863624
3825 * added files genutils.c and genutils.h which contain gen*
3826 debugged and optimised functions extracted from gen.c
3828 * glue.c: added variable 'externs' which holds extern symbols,
3829 pic16emitRegularMap: is modified to properly handle relocatable
3830 symbols under the new scheme,
3831 pic16createInterruptVect: is modified
3832 pic16printPublics: is modified to emit 'global' assembler directives,
3833 added pic16_printExterns to print extern symbols,
3834 pic16glue: initializes stack/frame pointer in the beginning of
3835 the assembly output. Temporary hack, will be corrected later,
3836 because gplink yet does not support stack and SDCC does not
3837 yet support a type of crt0.o object to create the final binary.
3839 * Removed many lines that contain 8051 legacy code.
3840 * The code is finally placed under a 'code' directive.
3841 * Added port specific options.
3843 * _process_pragma: simplified since now we do not need *special*
3844 include file to define SFR registers. But a separate header
3845 will be needed. This will be developed later.
3846 * _pic16_parseOptions: added, parses port specific options:
3847 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3848 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3849 --preplace-udata-with=
3851 * _pic16_setDefaultOptions: modified to initialize section names,
3852 but hack is temporarly out of order since it needs improvement.
3853 * _pic16_genAssemblerPreamble: configuration words are emitted by
3854 their address instead of their name. This part is incomplete and
3855 supports only the 18Fxx2 devices. Other devices will emit an error
3856 during assembly since they do not contain the same set of config
3858 * _pic16_genIVT: is modified,
3860 * pcode.c: added definitions for some hardware registers that are needed
3862 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3863 All PCI entries are updated. Now LFSR is supported.
3864 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3865 * added pic16_newpCodeOpLit2 to support instructions with
3866 two literal arguments
3867 * pic16_pCode2str: corrected code that emits assembler instructions
3868 with two literal operands and those that have an access bit modifier
3869 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3870 this fixes a bug which caused some labels to be lost, when an
3871 assembler directive was added, i.e. banksel,
3872 * pic16_FixRegisterBanking: improved logic that causes the insertion
3874 * InlineFunction: functions that are called once, are not any more
3875 inlined. This can be a port option in the future,
3877 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3879 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3880 hold the corresponding uninitialized symbols,
3881 * pic16_allocProcessorRegister: registers have explicit marked the
3883 * pic16_allocInternalRegister: registers are explicit marked as
3885 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3886 processing list, so bit registers were lost,
3889 * ralloc.h: added field 'accessBank' and original symbol operand
3890 in register definition,
3891 * removed the field isMapped from register definition,
3893 ** Several functions have been removed from various sources:
3894 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3895 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3896 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3897 pic16_assignRelocatableRegisters
3899 ** others have been introduced:
3900 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3901 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3903 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3905 * support/scripts/inc2h.pl: changed definition of BIT_AT
3906 to emit 'sbit at' instead of 'bit at'. This was a request.
3908 PIC16 port related preliminary changes:
3909 * gen.c: prefixed function popRegFromString with
3910 pic16_ and all references to it corrected
3911 * pcode.c: all pic16_pc_* hardware registers prefixed
3912 with underscore (_),
3913 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3914 * ralloc.c: newReg(): when register is REG_SFR then
3915 set address to rIdx,
3916 pic16_allocProcessorRegister(): marks register wasUsed=0
3917 pic16_writeUsedRegs(): added a call to assign processor
3918 registers via pic16_assignFixedRegisters
3920 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3922 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3923 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3924 variables in unused register banks. Also the SSEG is placed
3925 wherever there is enough space for it, and IDATA can be anywhere
3926 in internal RAM. For now compile using -Wl-Y[stack_size].
3927 The mem file is different for this option as well, since it
3928 makes no sense of talking about DSEG lenght.
3930 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3932 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3933 in certain cases, e.g. when ROM assignment, patch provided
3934 from Albert den Haan.
3936 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4959 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4960 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4961 type for bits was changed. It resulted in bit variables becoming
4962 global, which is not permitted in PIC 14 assembly output.

4979 A few small changes that speed up the peephole optimizer.
4983 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4985 Try to make the peephole optimizer smarter by maintaining
4986 an association between the assembly source code and the
4987 iCodes that originated them. Put this information to use
4988 with a new peephole rule condition "notVolatile" so that
4989 the rules can be aggressive yet still safe.
4994 * src/mcs51/peeph.def
4996 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5000 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5001 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5002 if the left or right operand symbols have the accuse flag set.
5004 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5006 Changed the type of the result of the ! (NOT) operator to char;
5007 previously it returned the same type as the source. This allows
5008 us to eliminate all the genFloatNot functions (all of its target
5009 implementations were very buggy) since !float can use the same
5012 * src/SDCCicode.c (ast2iCode): ! returns char

5021 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5022 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5023 during interrupts. Ensure WSAVE is located at a shared bank address.
5024 2. Fixed page selection in some places
5025 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5026 the registers name strings.
5027 4. Fixed "signed / unsigned compare" compiler warnings.
5028 5. The PIC port manages its own allocation of the general purpose
5029 registers, but makes no attempt to reuse them. As a result when
5030 compiling it soon runs out of general purpose registers. Some
5031 additional code was added to the files pcode.c and device.c to walk
5032 through the function call tree and rename the registers so that they
5042 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5043 genPlus() & genMinus() when the result is the same as left or right

5049 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5051 Made bitfield a distinct type from bit so that bitfields
5052 convert as per ANSI C and bits retain their traditional
5053 boolean style behaviour. Implemented bitfield support in
5061 * src/ds390/gen.c: bit v bitfield split
5062 * src/z80/gen.c: New support for bitfields
5063 * support/regression/tests/bitfields.c: reenabled z80,
5066 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5068 Rules 246.x, 247.x relate to bitfields, the others speed up
5069 access to xdata mapped I/O devices.
5071 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5073 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5075 Cleaned up genPackBits and genUnpackBits and added two helper

5085 Fixed bug #748310 (pointer to function type mishandled when the
5086 function name is omitted). Also fixed a SIGSEGV when a function
5087 attribute (reentrant, etc) is used on a non-function or on a
5088 function but misplaced before the parameter list.

5106 * src/SDCC.y: More bitfield related error checking
5108 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
5109 * support/Util/SDCCerr.h,
5110 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
5111 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs

5115 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5117 Made the constant following the "interrupt" keyword optional. If
5118 omitted, the function will not automatically be given an entry
5119 in the interrupt vector table (similar to #pragma NOIV, but
5120 less syntacticly kludgy). The interrupt number is also now
5121 range checked. Also fixed a bug in the high order bit example
5128 * support/Util/SDCCerr.c
5129 * support/Util/SDCCerr.h
5132 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5139 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5140 be re-activated by defining REDUCE_LITERALS)
5141 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5142 unsigned, but are signed by default
5143 * src/SDCCval.c (constVal): rearranged
5144 * src/SDCCval.c (valMod): preliminary fix
5145 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5188 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5189 * src/SDCCval.c (valDiv, valMod): fixed signdness
5190 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5191 signedness of modulo, left and right shift
5192 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

5653 support for the PIc16 port in the ports table, when executing
5654 the compiler with no port specified on command line, a default
5655 port is selected with the new macro DEFAULT_PORT which is
5656 defined in port.h, in setDefaultOptions() linkOptions is removed
5657 from initialization assignment, since now it is a set,
5658 parseCmdLine uses setParseWithComma for linkOptions, in
5659 linkEdit() linkOptions are accessed with new function indexSet()
5660 which returns the i'th item of a set variable. See SDCCset.c, in
5661 linkEdit() when calling buildCmdLine(), added linkOptions as
5662 last argument. Now users can pass arguments to gplink via the

6727 2003-01-04 <johan AT balder>
6729 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6731 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6732 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6734 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6735 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6744 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6745 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6747 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6749 * in \sdcc\as\mcs51\ changed these files in order to create an
6750 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6751 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6752 following files to include the previous two files: aslink.dsp,
6753 Makefile.aslink, Makefile.bcc, and Makefile.in.
6755 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6756 .adb instead of .cdb
6758 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6760 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6761 value from option --iram-size.
6763 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6765 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6768 2002-09-18 <wiml AT hhhh.org>
6770 * SDCClrange.h: exposed setFromRange() and setToRange()
6771 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6772 packRegsForAccUse() (bug 542397)
6773 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6774 multiple times and emitting the fetch operations more than once
6775 added aopGetUsesAcc() function to allow binary operators to
6776 fetch their operands in the correct order; made genMinus() emit
6777 compact code for X = LITERAL - Y
6779 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6780 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6781 sprintf() in line 1267.
6783 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6784 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6787 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6788 Changes to aslink (All the changes are marked with 'JCF'):
6790 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6793 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6794 area BSEG. Also moves, if possible, the DATA area down into the internal
6795 ram so more space is available.
6797 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6800 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6801 not bytes. Function summary() which creates a memory usage summary
6802 file with extension .mem. Reports of overlaping stack and small stack
6803 size. If the space for the stack is less than 16 bytes aslink trows a
6806 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6807 the 8051. Option 'y' for memory summary output file.
6809 Changes to sdcc (All the changes are marked with 'JCF'):
6811 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6813 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6814 overlaying area for it (uses RegBankUsed[4]).
6816 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6817 bank zero as used by default. By default aslink locates the stack
6818 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6819 the creation of the .mem file. Delegates the allocation of data area
6820 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6821 the begining of the stack area to aslink.
6823 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6824 glue() in SDCCglue.c creates an area for it.
6826 2002-09-03 Borut Razem <borut.razem AT siol.net>
6827 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6828 sdcc/src/pic/glue.c:
6829 introduced atexit() handler for teporay files removal in case of
6830 errors, assertions, ...
6832 2002-08-29 Borut Razem <borut.razem AT siol.net>
6833 * sdcc/support/cpp2/auto-host_vc_in.h:
6834 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6835 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6836 Maybe there is a similar problem with BORLANDC? It should be checked!
6838 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6839 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6840 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6841 was not executed, and the compiler (cl) launched a warning:
6842 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6844 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6845 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6847 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6848 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6850 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6851 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6852 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6853 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6854 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6855 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6856 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6857 - added Release configuration in VS projects
6858 - review of compiler an linker options
6859 - VC .exe files are generated in bin_vc directory, not to interfere
6860 with binaries generated from other projects (cygwin, mingw, bcc ...)
6862 * sdcc/src/yacc.dsp: added
6864 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6865 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6866 and insert the version number definitions from .version
6868 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6870 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6871 added - genarate auto-host.h using auto-host_vc_in.h as template
6874 removed from CVS, generated automatically
6876 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6877 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6879 2002-08-11 Borut Razem <borut.razem AT siol.net>
6880 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6882 2002-08-10 Borut Razem <borut.razem AT siol.net>
6883 * src/SDCCmain.c (main):
6884 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6885 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6886 The consequence was that some temporary files were not removed.
6889 unification of code in functions tempfilename() and tempfile():
6890 function tempnam() is defined in Visual Studio 6.0 and .NET
6892 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6894 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6895 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6896 - removed compiler command line option /WX: Treats all warnings as errors
6897 - update a list of source files, included into the project
6899 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6900 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6901 changed project type to Generic Project so that can be correcly converted to VS.NET project
6903 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6905 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6907 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6909 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6910 added return 0 statements after assert() to make compiler happy
6912 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6913 added newline in the def file to keep MSC compiler satisfied
6915 * sdcc/src/z80/gen.c:
6916 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6917 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6918 - solved MSC error in function aopDump()
6920 * sdcc_vc.h: define PREFIX as "\\sdcc"
6922 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6923 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6925 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6926 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6927 - Rewrote the register banking algorithm.
6928 - Added pCode live-range analysis to registers (for now, only non-used and
6929 singly-used registers optimized away)
6931 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6933 * 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.
6935 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6936 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

6958 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6960 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6962 2002-03-28 Johan Knol <johan AT balder>
6964 * src/SDCCval.c: fixed bug #532436
6966 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6968 Added "char *Processor" field to the port structure.
6971 Added -p option. Allows port dependent processor to be specified.
6974 Initialized the new field char *Processor field to NULL in all ports
6977 Compiler generated registers for interrupt context saving
6978 were not getting allocated.
6980 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6983 Fixed left shift. Will promote the left side of a left shift
6984 if a) left shifting more than size of operand or b) when assigned
6985 to something size > size of left side
6987 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6989 tons of changes. Register allocation has been
6990 rewritten. Added customization for the various PICs. Flow
6991 analysis is restructured. ...
