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

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

440 temporary registers, its a buggy feature and will be removed,
441 * (pic16_popGet): set register instance field in AOP_CRY,
442 * (pic16_outBitC): fixed for results in size greater than 1,
443 * (genUminusFloat): fixed for pic16, ported code from mcs51,
444 * (pic16_storeForReturn): optimized return of 0,
445 * (genCmp): experimental code for new genCmp which uses PIC18's
446 special compare&skip instructions. Initial tests fail some times
447 with variables grater than 1 byte in size, so new code is disabled,
448 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
450 * (genCast): began a fix to optimize the casting of a bit to another

3474 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3476 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3477 loaded with the linker search paths (-L arguments) and the libraries
3478 to be linked with the current source (-l arguments). Changes
3479 currently will affect only the pic16 port.
3480 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3481 include path the port specific paths and port specific libraries,
3482 * gplink command now contains the $3 argument,
3483 * src/pic16/device.h,
3484 * src/pic16/device.c,: structure PIC_device is made public and
3485 renamed to PIC16_device, the same for variable Pics which is renamed

3500 Documenting changes from previous commits.
3501 * configure.in (version 1.56),
3502 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3503 when generating output files to configure the pic16 library,
3504 but now I've commented it out, since gputils aren't installed in the
3505 SF compile farm, so library won't compile
3507 * device/lib/Makefile.in (version 1.56): initially I've added in
3508 target 'all' the prerequestive 'model-pic16' so it compiled the
3509 pic16 library, but now I've commented it out for the same reasons
3511 * added targets 'model-pic16' and 'objects-pic16' to compile the
3513 * added target 'port-specific-objects-pic16' to handle the
3514 generated libraries and copy them into the build/ directory
3515 * added target 'clean-intermediate-pic16' to clean intermediate
3516 files into pic16 directory
3517 * in target 'installdirs' added line to create directory pic16 in
3518 the installation path
3520 * device/include/Makefile.in (version 1.11): in target 'install'
3521 added lines to copy all header files to installation path,
3522 * in target 'installdirs' added line create directory for pic16
3523 headers in the installation path

3538 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3539 option so that it actually works. Made it specific to the z80, since
3540 the gbz80 doesn't have these kinds of I/O ports.
3542 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3544 * device/include/z180.h,

3566 Mainly changes to support compilation of the device libraries
3567 * src/pic16/device.c: stack is allocated via symbol and not
3568 via literal number. The symbol is placed in the corresponding
3569 position of the data ram
3570 * (pic16_dump_section): relocatable and absolute uninitialized
3571 data are now emitted in sorted order to reduce section naming,
3572 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3573 weren't marked as being in the access bank,
3575 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3577 Added portion of GNU PIC Library under the directory
3578 device/include/pic16 and device/lib/pic16. These files
3579 contain the declarations of SFRs for the PIC18Fxx2 devices.
3580 The directory is initialized via configure from toplevel.
3582 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3610 all over. Telling LaTeX to be less strict with word spacing
3611 to better keep the right margin. Changed some notes about
3612 maintainance of the ports in section 3.2.1 - is it OK like this?
3614 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3616 SDCC source changes:
3617 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3623 processor registers declared internally by the port are emitted in
3624 the translation as equates,
3625 * src/pic16/gen.c: inline code is passed unprocessed to the

3766 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3768 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3769 (default behaviour).
3771 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3773 A python script to validate compiler diagnostic messages. It can be
3774 used to verify that sdcc complains about bad c source code and
3775 gives a good location of the error.
3776 * support/valdiag/Makefile,
3777 * support/valdiag/valdiag.py,
3778 * support/valdiag/tests/*
3780 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3795 Bug reported from Jesus Calvino-Fraga
3797 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3799 * sdcc.spec: updated
3800 * device/include/Makefile.in: don't install CVS directories
3801 * device/lib/Makefile.in: added removal of CVS directories after install
3802 * doc/Makefile: fixed install, added local_icons
3803 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3804 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3805 * src/ds390/gen.c (genRightShift): fixed bug #870788
3806 * src/SDCCast.c (decorateType): fixed bug #870781
3808 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3810 PIC16 port related changes:
3811 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3812 added variable stackPos,
3814 * gen.c: genCall, assignResultValue: added support for
3815 pushing/retrieving function parameters to/from stack,
3816 genFunction,genEndFunction: setup stack frame for the
3818 genAddrOf: will be changed according to bug 863624
3820 * added files genutils.c and genutils.h which contain gen*
3821 debugged and optimised functions extracted from gen.c
3823 * glue.c: added variable 'externs' which holds extern symbols,
3824 pic16emitRegularMap: is modified to properly handle relocatable
3825 symbols under the new scheme,
3826 pic16createInterruptVect: is modified
3827 pic16printPublics: is modified to emit 'global' assembler directives,
3828 added pic16_printExterns to print extern symbols,
3829 pic16glue: initializes stack/frame pointer in the beginning of
3830 the assembly output. Temporary hack, will be corrected later,
3831 because gplink yet does not support stack and SDCC does not
3832 yet support a type of crt0.o object to create the final binary.
3834 * Removed many lines that contain 8051 legacy code.
3835 * The code is finally placed under a 'code' directive.
3836 * Added port specific options.
3838 * _process_pragma: simplified since now we do not need *special*
3839 include file to define SFR registers. But a separate header
3840 will be needed. This will be developed later.
3841 * _pic16_parseOptions: added, parses port specific options:
3842 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3843 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3844 --preplace-udata-with=
3846 * _pic16_setDefaultOptions: modified to initialize section names,
3847 but hack is temporarly out of order since it needs improvement.
3848 * _pic16_genAssemblerPreamble: configuration words are emitted by
3849 their address instead of their name. This part is incomplete and
3850 supports only the 18Fxx2 devices. Other devices will emit an error
3851 during assembly since they do not contain the same set of config
3853 * _pic16_genIVT: is modified,
3855 * pcode.c: added definitions for some hardware registers that are needed
3857 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3858 All PCI entries are updated. Now LFSR is supported.
3859 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3860 * added pic16_newpCodeOpLit2 to support instructions with
3861 two literal arguments
3862 * pic16_pCode2str: corrected code that emits assembler instructions
3863 with two literal operands and those that have an access bit modifier
3864 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3865 this fixes a bug which caused some labels to be lost, when an
3866 assembler directive was added, i.e. banksel,
3867 * pic16_FixRegisterBanking: improved logic that causes the insertion
3869 * InlineFunction: functions that are called once, are not any more
3870 inlined. This can be a port option in the future,
3872 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3874 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3875 hold the corresponding uninitialized symbols,
3876 * pic16_allocProcessorRegister: registers have explicit marked the
3878 * pic16_allocInternalRegister: registers are explicit marked as
3880 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3881 processing list, so bit registers were lost,
3884 * ralloc.h: added field 'accessBank' and original symbol operand
3885 in register definition,
3886 * removed the field isMapped from register definition,
3888 ** Several functions have been removed from various sources:
3889 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3890 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3891 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3892 pic16_assignRelocatableRegisters
3894 ** others have been introduced:
3895 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3896 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3898 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3900 * support/scripts/inc2h.pl: changed definition of BIT_AT
3901 to emit 'sbit at' instead of 'bit at'. This was a request.
3903 PIC16 port related preliminary changes:
3904 * gen.c: prefixed function popRegFromString with
3905 pic16_ and all references to it corrected
3906 * pcode.c: all pic16_pc_* hardware registers prefixed
3907 with underscore (_),
3908 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3909 * ralloc.c: newReg(): when register is REG_SFR then
3910 set address to rIdx,
3911 pic16_allocProcessorRegister(): marks register wasUsed=0
3912 pic16_writeUsedRegs(): added a call to assign processor
3913 registers via pic16_assignFixedRegisters
3915 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3917 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3918 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3919 variables in unused register banks. Also the SSEG is placed
3920 wherever there is enough space for it, and IDATA can be anywhere
3921 in internal RAM. For now compile using -Wl-Y[stack_size].
3922 The mem file is different for this option as well, since it
3923 makes no sense of talking about DSEG lenght.
3925 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3927 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3928 in certain cases, e.g. when ROM assignment, patch provided
3929 from Albert den Haan.
3931 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4954 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4955 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4974 A few small changes that speed up the peephole optimizer.
4978 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4980 Try to make the peephole optimizer smarter by maintaining
4981 an association between the assembly source code and the
4982 iCodes that originated them. Put this information to use
4983 with a new peephole rule condition "notVolatile" so that
4984 the rules can be aggressive yet still safe.
4989 * src/mcs51/peeph.def
4991 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4995 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4996 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4997 if the left or right operand symbols have the accuse flag set.
4999 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5001 Changed the type of the result of the ! (NOT) operator to char;
5002 previously it returned the same type as the source. This allows
5003 us to eliminate all the genFloatNot functions (all of its target
5004 implementations were very buggy) since !float can use the same
5007 * src/SDCCicode.c (ast2iCode): ! returns char

5016 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5017 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5018 during interrupts. Ensure WSAVE is located at a shared bank address.
5019 2. Fixed page selection in some places
5020 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5021 the registers name strings.
5022 4. Fixed "signed / unsigned compare" compiler warnings.
5023 5. The PIC port manages its own allocation of the general purpose
5024 registers, but makes no attempt to reuse them. As a result when
5025 compiling it soon runs out of general purpose registers. Some
5026 additional code was added to the files pcode.c and device.c to walk
5027 through the function call tree and rename the registers so that they
5037 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5038 genPlus() & genMinus() when the result is the same as left or right

5044 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5046 Made bitfield a distinct type from bit so that bitfields
5047 convert as per ANSI C and bits retain their traditional
5048 boolean style behaviour. Implemented bitfield support in
5056 * src/ds390/gen.c: bit v bitfield split
5057 * src/z80/gen.c: New support for bitfields
5058 * support/regression/tests/bitfields.c: reenabled z80,
5061 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5063 Rules 246.x, 247.x relate to bitfields, the others speed up
5064 access to xdata mapped I/O devices.
5066 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5068 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5070 Cleaned up genPackBits and genUnpackBits and added two helper

5080 Fixed bug #748310 (pointer to function type mishandled when the
5081 function name is omitted). Also fixed a SIGSEGV when a function
5082 attribute (reentrant, etc) is used on a non-function or on a
5083 function but misplaced before the parameter list.

5112 Made the constant following the "interrupt" keyword optional. If
5113 omitted, the function will not automatically be given an entry
5114 in the interrupt vector table (similar to #pragma NOIV, but
5115 less syntacticly kludgy). The interrupt number is also now
5116 range checked. Also fixed a bug in the high order bit example
5123 * support/Util/SDCCerr.c

5649 the compiler with no port specified on command line, a default
5650 port is selected with the new macro DEFAULT_PORT which is
5651 defined in port.h, in setDefaultOptions() linkOptions is removed
5652 from initialization assignment, since now it is a set,
5653 parseCmdLine uses setParseWithComma for linkOptions, in

6722 2003-01-04 <johan AT balder>
6724 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6726 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6727 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6729 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6730 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6739 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6740 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6742 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6744 * in \sdcc\as\mcs51\ changed these files in order to create an
6745 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6746 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6747 following files to include the previous two files: aslink.dsp,
6748 Makefile.aslink, Makefile.bcc, and Makefile.in.
6750 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6751 .adb instead of .cdb
6753 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6755 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6756 value from option --iram-size.
6758 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6760 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6763 2002-09-18 <wiml AT hhhh.org>
6765 * SDCClrange.h: exposed setFromRange() and setToRange()
6766 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6767 packRegsForAccUse() (bug 542397)
6768 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6769 multiple times and emitting the fetch operations more than once
6770 added aopGetUsesAcc() function to allow binary operators to
6771 fetch their operands in the correct order; made genMinus() emit
6772 compact code for X = LITERAL - Y
6774 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6775 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6776 sprintf() in line 1267.
6778 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6779 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6782 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6783 Changes to aslink (All the changes are marked with 'JCF'):
6785 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6788 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6789 area BSEG. Also moves, if possible, the DATA area down into the internal
6790 ram so more space is available.
6792 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6795 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6796 not bytes. Function summary() which creates a memory usage summary
6797 file with extension .mem. Reports of overlaping stack and small stack
6798 size. If the space for the stack is less than 16 bytes aslink trows a
6801 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6802 the 8051. Option 'y' for memory summary output file.
6804 Changes to sdcc (All the changes are marked with 'JCF'):
6806 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6808 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6809 overlaying area for it (uses RegBankUsed[4]).
6811 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6812 bank zero as used by default. By default aslink locates the stack
6813 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6814 the creation of the .mem file. Delegates the allocation of data area
6815 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6816 the begining of the stack area to aslink.
6818 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6819 glue() in SDCCglue.c creates an area for it.
6821 2002-09-03 Borut Razem <borut.razem AT siol.net>
6822 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6823 sdcc/src/pic/glue.c:
6824 introduced atexit() handler for teporay files removal in case of
6825 errors, assertions, ...
6827 2002-08-29 Borut Razem <borut.razem AT siol.net>
6828 * sdcc/support/cpp2/auto-host_vc_in.h:
6829 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6830 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6831 Maybe there is a similar problem with BORLANDC? It should be checked!
6833 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6834 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6835 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6836 was not executed, and the compiler (cl) launched a warning:
6837 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6839 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6840 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6842 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6843 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6845 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6846 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6847 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6848 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6849 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6850 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6851 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6852 - added Release configuration in VS projects
6853 - review of compiler an linker options
6854 - VC .exe files are generated in bin_vc directory, not to interfere
6855 with binaries generated from other projects (cygwin, mingw, bcc ...)
6857 * sdcc/src/yacc.dsp: added
6859 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6860 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6861 and insert the version number definitions from .version
6863 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6865 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6866 added - genarate auto-host.h using auto-host_vc_in.h as template
6869 removed from CVS, generated automatically
6871 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6872 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6874 2002-08-11 Borut Razem <borut.razem AT siol.net>
6875 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6877 2002-08-10 Borut Razem <borut.razem AT siol.net>
6878 * src/SDCCmain.c (main):
6879 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6880 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6881 The consequence was that some temporary files were not removed.
6884 unification of code in functions tempfilename() and tempfile():
6885 function tempnam() is defined in Visual Studio 6.0 and .NET
6887 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6889 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6890 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6891 - removed compiler command line option /WX: Treats all warnings as errors
6892 - update a list of source files, included into the project
6894 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6895 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6896 changed project type to Generic Project so that can be correcly converted to VS.NET project
6898 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6900 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6902 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6904 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6905 added return 0 statements after assert() to make compiler happy
6907 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6908 added newline in the def file to keep MSC compiler satisfied
6910 * sdcc/src/z80/gen.c:
6911 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6912 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6913 - solved MSC error in function aopDump()
6915 * sdcc_vc.h: define PREFIX as "\\sdcc"
6917 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6918 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6920 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6921 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6922 - Rewrote the register banking algorithm.
6923 - Added pCode live-range analysis to registers (for now, only non-used and
6924 singly-used registers optimized away)
6926 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6928 * 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.
6930 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6931 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6933 2002-04-22 Michael Hope <michaelh AT vroom>

6949 * src/z80/peeph.def: Added transpose redundent load rule.
6951 * src/z80/main.c: Added force callee saves for jaune.
6953 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6955 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6957 2002-03-28 Johan Knol <johan AT balder>
6959 * src/SDCCval.c: fixed bug #532436
6961 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6963 Added "char *Processor" field to the port structure.
6966 Added -p option. Allows port dependent processor to be specified.
6969 Initialized the new field char *Processor field to NULL in all ports
6972 Compiler generated registers for interrupt context saving
6973 were not getting allocated.
6975 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6978 Fixed left shift. Will promote the left side of a left shift
6979 if a) left shifting more than size of operand or b) when assigned
6980 to something size > size of left side
6982 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6984 tons of changes. Register allocation has been
6985 rewritten. Added customization for the various PICs. Flow
6986 analysis is restructured. ...
6992 Added. device.c is a PIC port hack to accomodate variations
6995 2002-03-13 Michael Hope <michaelh AT vroom>
6997 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6999 2002-03-04 johanknol <johanknol AT manik>
