384 Adding support for replacing ljmps with sjmps in jumptables
385 generated for switch statements. For now you need to set the
386 environment variable SDCC_SJMP_JUMPTABLE to enable this.
387 Now 4 algorithms for mcs51 jumptable generation are used:
388 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
389 addresses loaded pc-relative for up to 112 cases and stack-pushing
390 target addresses loaded with offset from dptr for up to 256 cases.

417 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
418 to call when a stack overflow occurs,
419 * (malloc.h): added CVS Id tag,
420 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
422 * added libc directory. The current version of LibC contains string
423 functions, ctype functions and macros and some functions of the
424 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
425 be extensively tested in the future. Standard disclaimer here.
426 Library is not automatically build yet. But one can build it by
427 invoking 'make' inside the libc directory.
428 * added ADC library under libio. Preliminary version yet.

436 * (pic16_outBitC): fixed for results in size greater than 1,
437 * (genUminusFloat): fixed for pic16, ported code from mcs51,
438 * (pic16_storeForReturn): optimized return of 0,
439 * (genCmp): experimental code for new genCmp which uses PIC18's
440 special compare&skip instructions. Initial tests fail some times
441 with variables grater than 1 byte in size, so new code is disabled,
442 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
444 * (genCast): began a fix to optimize the casting of a bit to another
445 bit, now assigning a bitfield to another bitfield will fail, sorry,
446 * src/pic16/main.c: disabled the use of lr-support feature,
447 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3468 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3470 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3471 loaded with the linker search paths (-L arguments) and the libraries
3472 to be linked with the current source (-l arguments). Changes
3473 currently will affect only the pic16 port.
3474 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3475 include path the port specific paths and port specific libraries,
3476 * gplink command now contains the $3 argument,
3477 * src/pic16/device.h,
3478 * src/pic16/device.c,: structure PIC_device is made public and
3479 renamed to PIC16_device, the same for variable Pics which is renamed

3494 Documenting changes from previous commits.
3495 * configure.in (version 1.56),
3496 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3497 when generating output files to configure the pic16 library,
3498 but now I've commented it out, since gputils aren't installed in the
3499 SF compile farm, so library won't compile
3501 * device/lib/Makefile.in (version 1.56): initially I've added in
3502 target 'all' the prerequestive 'model-pic16' so it compiled the
3503 pic16 library, but now I've commented it out for the same reasons
3505 * added targets 'model-pic16' and 'objects-pic16' to compile the
3507 * added target 'port-specific-objects-pic16' to handle the
3508 generated libraries and copy them into the build/ directory
3509 * added target 'clean-intermediate-pic16' to clean intermediate
3510 files into pic16 directory
3511 * in target 'installdirs' added line to create directory pic16 in
3512 the installation path
3514 * device/include/Makefile.in (version 1.11): in target 'install'
3515 added lines to copy all header files to installation path,
3516 * in target 'installdirs' added line create directory for pic16
3517 headers in the installation path

3532 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3533 option so that it actually works. Made it specific to the z80, since
3534 the gbz80 doesn't have these kinds of I/O ports.
3536 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3538 * device/include/z180.h,

3562 via literal number. The symbol is placed in the corresponding
3563 position of the data ram
3564 * (pic16_dump_section): relocatable and absolute uninitialized
3565 data are now emitted in sorted order to reduce section naming,
3566 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3567 weren't marked as being in the access bank,
3569 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3571 Added portion of GNU PIC Library under the directory
3572 device/include/pic16 and device/lib/pic16. These files
3573 contain the declarations of SFRs for the PIC18Fxx2 devices.
3574 The directory is initialized via configure from toplevel.
3576 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3601 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3603 * doc/sdccman.lyx: Moved and added some sections, small changes
3604 all over. Telling LaTeX to be less strict with word spacing
3605 to better keep the right margin. Changed some notes about
3606 maintainance of the ports in section 3.2.1 - is it OK like this?
3608 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3610 SDCC source changes:
3611 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3645 UPPER for immediate operands,
3646 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3648 * src/pic16/peeph.def: all peepholes with movff are commented out,
3649 because there is a problem in the pcode peep optimizer,
3650 * src/pic16/ralloc.c: the register allocator can now reuse local

3760 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3762 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3763 (default behaviour).
3765 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3767 A python script to validate compiler diagnostic messages. It can be
3768 used to verify that sdcc complains about bad c source code and
3769 gives a good location of the error.
3770 * support/valdiag/Makefile,
3771 * support/valdiag/valdiag.py,
3772 * support/valdiag/tests/*
3774 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3787 * src/common.h: added ifndef/define/endif macros
3788 around the header file.
3789 Bug reported from Jesus Calvino-Fraga
3791 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3793 * sdcc.spec: updated
3794 * device/include/Makefile.in: don't install CVS directories
3795 * device/lib/Makefile.in: added removal of CVS directories after install
3796 * doc/Makefile: fixed install, added local_icons
3797 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3798 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3799 * src/ds390/gen.c (genRightShift): fixed bug #870788
3800 * src/SDCCast.c (decorateType): fixed bug #870781
3802 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3804 PIC16 port related changes:
3805 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3806 added variable stackPos,
3808 * gen.c: genCall, assignResultValue: added support for
3809 pushing/retrieving function parameters to/from stack,
3810 genFunction,genEndFunction: setup stack frame for the
3812 genAddrOf: will be changed according to bug 863624
3814 * added files genutils.c and genutils.h which contain gen*
3815 debugged and optimised functions extracted from gen.c
3817 * glue.c: added variable 'externs' which holds extern symbols,
3818 pic16emitRegularMap: is modified to properly handle relocatable
3819 symbols under the new scheme,
3820 pic16createInterruptVect: is modified
3821 pic16printPublics: is modified to emit 'global' assembler directives,
3822 added pic16_printExterns to print extern symbols,
3823 pic16glue: initializes stack/frame pointer in the beginning of
3824 the assembly output. Temporary hack, will be corrected later,
3825 because gplink yet does not support stack and SDCC does not
3826 yet support a type of crt0.o object to create the final binary.
3828 * Removed many lines that contain 8051 legacy code.
3829 * The code is finally placed under a 'code' directive.
3830 * Added port specific options.
3832 * _process_pragma: simplified since now we do not need *special*
3833 include file to define SFR registers. But a separate header
3834 will be needed. This will be developed later.
3835 * _pic16_parseOptions: added, parses port specific options:
3836 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3837 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3838 --preplace-udata-with=
3840 * _pic16_setDefaultOptions: modified to initialize section names,
3841 but hack is temporarly out of order since it needs improvement.
3842 * _pic16_genAssemblerPreamble: configuration words are emitted by
3843 their address instead of their name. This part is incomplete and
3844 supports only the 18Fxx2 devices. Other devices will emit an error
3845 during assembly since they do not contain the same set of config
3847 * _pic16_genIVT: is modified,
3849 * pcode.c: added definitions for some hardware registers that are needed
3851 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3852 All PCI entries are updated. Now LFSR is supported.
3853 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3854 * added pic16_newpCodeOpLit2 to support instructions with
3855 two literal arguments
3856 * pic16_pCode2str: corrected code that emits assembler instructions
3857 with two literal operands and those that have an access bit modifier
3858 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3859 this fixes a bug which caused some labels to be lost, when an
3860 assembler directive was added, i.e. banksel,
3861 * pic16_FixRegisterBanking: improved logic that causes the insertion
3863 * InlineFunction: functions that are called once, are not any more
3864 inlined. This can be a port option in the future,
3866 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3868 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3869 hold the corresponding uninitialized symbols,
3870 * pic16_allocProcessorRegister: registers have explicit marked the
3872 * pic16_allocInternalRegister: registers are explicit marked as
3874 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3875 processing list, so bit registers were lost,
3878 * ralloc.h: added field 'accessBank' and original symbol operand
3879 in register definition,
3880 * removed the field isMapped from register definition,
3882 ** Several functions have been removed from various sources:
3883 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3884 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3885 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3886 pic16_assignRelocatableRegisters
3888 ** others have been introduced:
3889 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3890 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3892 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3894 * support/scripts/inc2h.pl: changed definition of BIT_AT
3895 to emit 'sbit at' instead of 'bit at'. This was a request.
3897 PIC16 port related preliminary changes:
3898 * gen.c: prefixed function popRegFromString with
3899 pic16_ and all references to it corrected
3900 * pcode.c: all pic16_pc_* hardware registers prefixed
3901 with underscore (_),
3902 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3903 * ralloc.c: newReg(): when register is REG_SFR then
3904 set address to rIdx,
3905 pic16_allocProcessorRegister(): marks register wasUsed=0
3906 pic16_writeUsedRegs(): added a call to assign processor
3907 registers via pic16_assignFixedRegisters
3909 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3911 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3912 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3913 variables in unused register banks. Also the SSEG is placed
3914 wherever there is enough space for it, and IDATA can be anywhere
3915 in internal RAM. For now compile using -Wl-Y[stack_size].
3916 The mem file is different for this option as well, since it
3917 makes no sense of talking about DSEG lenght.
3919 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3921 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3922 in certain cases, e.g. when ROM assignment, patch provided
3923 from Albert den Haan.
3925 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4068 * src/mcs51/peephole.def,
4069 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4948 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4949 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4950 type for bits was changed. It resulted in bit variables becoming
4951 global, which is not permitted in PIC 14 assembly output.

4968 A few small changes that speed up the peephole optimizer.
4972 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4974 Try to make the peephole optimizer smarter by maintaining
4975 an association between the assembly source code and the
4976 iCodes that originated them. Put this information to use
4977 with a new peephole rule condition "notVolatile" so that
4978 the rules can be aggressive yet still safe.
4983 * src/mcs51/peeph.def
4985 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4989 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4990 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4991 if the left or right operand symbols have the accuse flag set.
4993 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4995 Changed the type of the result of the ! (NOT) operator to char;
4996 previously it returned the same type as the source. This allows
4997 us to eliminate all the genFloatNot functions (all of its target
4998 implementations were very buggy) since !float can use the same
5001 * src/SDCCicode.c (ast2iCode): ! returns char

5010 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5011 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5012 during interrupts. Ensure WSAVE is located at a shared bank address.
5013 2. Fixed page selection in some places
5014 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5015 the registers name strings.
5016 4. Fixed "signed / unsigned compare" compiler warnings.
5017 5. The PIC port manages its own allocation of the general purpose
5018 registers, but makes no attempt to reuse them. As a result when
5019 compiling it soon runs out of general purpose registers. Some
5020 additional code was added to the files pcode.c and device.c to walk
5021 through the function call tree and rename the registers so that they
5031 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5038 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5040 Made bitfield a distinct type from bit so that bitfields
5041 convert as per ANSI C and bits retain their traditional
5042 boolean style behaviour. Implemented bitfield support in
5050 * src/ds390/gen.c: bit v bitfield split
5051 * src/z80/gen.c: New support for bitfields
5052 * support/regression/tests/bitfields.c: reenabled z80,
5055 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5057 Rules 246.x, 247.x relate to bitfields, the others speed up
5058 access to xdata mapped I/O devices.
5060 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5062 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5064 Cleaned up genPackBits and genUnpackBits and added two helper

5074 Fixed bug #748310 (pointer to function type mishandled when the
5075 function name is omitted). Also fixed a SIGSEGV when a function
5076 attribute (reentrant, etc) is used on a non-function or on a
5077 function but misplaced before the parameter list.

5104 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5106 Made the constant following the "interrupt" keyword optional. If
5107 omitted, the function will not automatically be given an entry
5108 in the interrupt vector table (similar to #pragma NOIV, but
5109 less syntacticly kludgy). The interrupt number is also now
5110 range checked. Also fixed a bug in the high order bit example
5117 * support/Util/SDCCerr.c
5118 * support/Util/SDCCerr.h

5642 support for the PIc16 port in the ports table, when executing
5643 the compiler with no port specified on command line, a default
5644 port is selected with the new macro DEFAULT_PORT which is
5645 defined in port.h, in setDefaultOptions() linkOptions is removed
5646 from initialization assignment, since now it is a set,
5647 parseCmdLine uses setParseWithComma for linkOptions, in
5648 linkEdit() linkOptions are accessed with new function indexSet()
5649 which returns the i'th item of a set variable. See SDCCset.c, in
5650 linkEdit() when calling buildCmdLine(), added linkOptions as
5651 last argument. Now users can pass arguments to gplink via the

6716 2003-01-04 <johan AT balder>
6718 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6720 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6733 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6734 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6736 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6738 * in \sdcc\as\mcs51\ changed these files in order to create an
6739 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6740 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6741 following files to include the previous two files: aslink.dsp,
6742 Makefile.aslink, Makefile.bcc, and Makefile.in.
6744 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6745 .adb instead of .cdb
6747 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6749 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6750 value from option --iram-size.
6752 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6754 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6757 2002-09-18 <wiml AT hhhh.org>
6759 * SDCClrange.h: exposed setFromRange() and setToRange()
6760 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6761 packRegsForAccUse() (bug 542397)
6762 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6763 multiple times and emitting the fetch operations more than once
6764 added aopGetUsesAcc() function to allow binary operators to
6765 fetch their operands in the correct order; made genMinus() emit
6766 compact code for X = LITERAL - Y
6768 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6769 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6770 sprintf() in line 1267.
6772 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6773 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6776 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6777 Changes to aslink (All the changes are marked with 'JCF'):
6779 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6782 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6783 area BSEG. Also moves, if possible, the DATA area down into the internal
6784 ram so more space is available.
6786 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6789 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6790 not bytes. Function summary() which creates a memory usage summary
6791 file with extension .mem. Reports of overlaping stack and small stack
6792 size. If the space for the stack is less than 16 bytes aslink trows a
6795 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6796 the 8051. Option 'y' for memory summary output file.
6798 Changes to sdcc (All the changes are marked with 'JCF'):
6800 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6802 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6803 overlaying area for it (uses RegBankUsed[4]).
6805 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6806 bank zero as used by default. By default aslink locates the stack
6807 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6808 the creation of the .mem file. Delegates the allocation of data area
6809 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6810 the begining of the stack area to aslink.
6812 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6813 glue() in SDCCglue.c creates an area for it.
6815 2002-09-03 Borut Razem <borut.razem AT siol.net>
6816 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6817 sdcc/src/pic/glue.c:
6818 introduced atexit() handler for teporay files removal in case of
6819 errors, assertions, ...
6821 2002-08-29 Borut Razem <borut.razem AT siol.net>
6822 * sdcc/support/cpp2/auto-host_vc_in.h:
6823 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6824 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6825 Maybe there is a similar problem with BORLANDC? It should be checked!
6827 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6828 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6829 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6830 was not executed, and the compiler (cl) launched a warning:
6831 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6833 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6834 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6836 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6837 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6839 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6840 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6841 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6842 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6843 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6844 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6845 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6846 - added Release configuration in VS projects
6847 - review of compiler an linker options
6848 - VC .exe files are generated in bin_vc directory, not to interfere
6849 with binaries generated from other projects (cygwin, mingw, bcc ...)
6851 * sdcc/src/yacc.dsp: added
6853 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6854 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6855 and insert the version number definitions from .version
6857 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6859 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6860 added - genarate auto-host.h using auto-host_vc_in.h as template
6863 removed from CVS, generated automatically
6865 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6866 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6868 2002-08-11 Borut Razem <borut.razem AT siol.net>
6869 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6871 2002-08-10 Borut Razem <borut.razem AT siol.net>
6872 * src/SDCCmain.c (main):
6873 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6874 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6875 The consequence was that some temporary files were not removed.
6878 unification of code in functions tempfilename() and tempfile():
6879 function tempnam() is defined in Visual Studio 6.0 and .NET
6881 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6883 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6884 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6885 - removed compiler command line option /WX: Treats all warnings as errors
6886 - update a list of source files, included into the project
6888 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6889 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6890 changed project type to Generic Project so that can be correcly converted to VS.NET project
6892 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6894 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6896 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6898 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6899 added return 0 statements after assert() to make compiler happy
6901 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6902 added newline in the def file to keep MSC compiler satisfied
6904 * sdcc/src/z80/gen.c:
6905 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6906 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6907 - solved MSC error in function aopDump()
6909 * sdcc_vc.h: define PREFIX as "\\sdcc"
6911 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6912 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6914 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6915 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6916 - Rewrote the register banking algorithm.
6917 - Added pCode live-range analysis to registers (for now, only non-used and
6918 singly-used registers optimized away)
6920 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6922 * 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.
6924 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6925 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6927 2002-04-22 Michael Hope <michaelh AT vroom>

6943 * src/z80/peeph.def: Added transpose redundent load rule.
6945 * src/z80/main.c: Added force callee saves for jaune.
6947 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6949 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6951 2002-03-28 Johan Knol <johan AT balder>
6953 * src/SDCCval.c: fixed bug #532436
6955 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6957 Added "char *Processor" field to the port structure.
6960 Added -p option. Allows port dependent processor to be specified.
6963 Initialized the new field char *Processor field to NULL in all ports
6966 Compiler generated registers for interrupt context saving
6967 were not getting allocated.
6969 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6972 Fixed left shift. Will promote the left side of a left shift
6973 if a) left shifting more than size of operand or b) when assigned
6974 to something size > size of left side
6976 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6978 tons of changes. Register allocation has been
6979 rewritten. Added customization for the various PICs. Flow
6980 analysis is restructured. ...
6986 Added. device.c is a PIC port hack to accomodate variations
6989 2002-03-13 Michael Hope <michaelh AT vroom>
6991 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6993 2002-03-04 johanknol <johanknol AT manik>
6995 * /src/SDCCval.c: fixed
6997 const unsigned char arr[][2] = { { 0, 1 } };
