452 environment variable SDCC_SJMP_JUMPTABLE to enable this.
453 Now 4 algorithms for mcs51 jumptable generation are used:
454 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
455 addresses loaded pc-relative for up to 112 cases and stack-pushing
456 target addresses loaded with offset from dptr for up to 256 cases.
458 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
459 * src/mcs51/main.c: adapted constants for switch table generation
460 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

480 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
482 Large cummulative patch for pic16 port.
483 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
484 to call when a stack overflow occurs,
485 * (malloc.h): added CVS Id tag,
486 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
488 * added libc directory. The current version of LibC contains string
489 functions, ctype functions and macros and some functions of the
490 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
491 be extensively tested in the future. Standard disclaimer here.
492 Library is not automatically build yet. But one can build it by
493 invoking 'make' inside the libc directory.
494 * added ADC library under libio. Preliminary version yet.
496 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
497 * src/pic16/gen.c (aopForRemat): asmop size is filled by
498 aopForRemat() now and not by pic16_aopOp(),

504 * (pic16_storeForReturn): optimized return of 0,
505 * (genCmp): experimental code for new genCmp which uses PIC18's
506 special compare&skip instructions. Initial tests fail some times
507 with variables grater than 1 byte in size, so new code is disabled,
508 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
510 * (genCast): began a fix to optimize the casting of a bit to another
511 bit, now assigning a bitfield to another bitfield will fail, sorry,
512 * src/pic16/main.c: disabled the use of lr-support feature,
513 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
514 * added some function prototypes, added function _debugf prototype,
515 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
516 bits with offset (case PO_GPR_BIT),
517 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
519 * (isBankInstruction): modified to return 0 for no banking instruction,
520 and 1 for banking instruction,
521 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
522 caused stop processing pCodes after a inline assembly block,
523 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
524 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
525 registers when it shouldn't,
526 * src/pic16/ralloc.c (allocReg): add preliminary support for
527 supporting a limited set of temporary registers,
529 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

532 genDataPointerSet): ensure assignments always copy in MSB to LSB
534 (loadRegFromAop): recognize CLRH optimization,
535 (genFunction): optimize RECEIVE iCodes in reentrant functions
537 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3534 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3536 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3537 loaded with the linker search paths (-L arguments) and the libraries
3538 to be linked with the current source (-l arguments). Changes
3539 currently will affect only the pic16 port.
3540 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3541 include path the port specific paths and port specific libraries,
3542 * gplink command now contains the $3 argument,
3543 * src/pic16/device.h,
3544 * src/pic16/device.c,: structure PIC_device is made public and
3545 renamed to PIC16_device, the same for variable Pics which is renamed

3560 Documenting changes from previous commits.
3561 * configure.in (version 1.56),
3562 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3563 when generating output files to configure the pic16 library,
3564 but now I've commented it out, since gputils aren't installed in the
3565 SF compile farm, so library won't compile
3567 * device/lib/Makefile.in (version 1.56): initially I've added in
3568 target 'all' the prerequestive 'model-pic16' so it compiled the
3569 pic16 library, but now I've commented it out for the same reasons
3571 * added targets 'model-pic16' and 'objects-pic16' to compile the
3573 * added target 'port-specific-objects-pic16' to handle the
3574 generated libraries and copy them into the build/ directory
3575 * added target 'clean-intermediate-pic16' to clean intermediate
3576 files into pic16 directory
3577 * in target 'installdirs' added line to create directory pic16 in

3628 via literal number. The symbol is placed in the corresponding
3629 position of the data ram
3630 * (pic16_dump_section): relocatable and absolute uninitialized
3631 data are now emitted in sorted order to reduce section naming,
3632 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3633 weren't marked as being in the access bank,
3635 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3637 Added portion of GNU PIC Library under the directory
3638 device/include/pic16 and device/lib/pic16. These files
3639 contain the declarations of SFRs for the PIC18Fxx2 devices.
3640 The directory is initialized via configure from toplevel.
3642 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3644 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3670 all over. Telling LaTeX to be less strict with word spacing
3671 to better keep the right margin. Changed some notes about
3672 maintainance of the ports in section 3.2.1 - is it OK like this?
3674 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3714 * src/pic16/peeph.def: all peepholes with movff are commented out,
3715 because there is a problem in the pcode peep optimizer,
3716 * src/pic16/ralloc.c: the register allocator can now reuse local

3809 include information about variables allocated to the overlay
3812 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3814 * as/mcs51/lkmain.c: Help about -Y option

3826 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3828 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3829 (default behaviour).
3831 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3833 A python script to validate compiler diagnostic messages. It can be
3834 used to verify that sdcc complains about bad c source code and
3835 gives a good location of the error.
3836 * support/valdiag/Makefile,
3837 * support/valdiag/valdiag.py,
3838 * support/valdiag/tests/*
3840 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3842 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3853 * src/common.h: added ifndef/define/endif macros
3854 around the header file.
3855 Bug reported from Jesus Calvino-Fraga
3857 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3859 * sdcc.spec: updated
3860 * device/include/Makefile.in: don't install CVS directories
3861 * device/lib/Makefile.in: added removal of CVS directories after install
3862 * doc/Makefile: fixed install, added local_icons
3863 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3864 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3865 * src/ds390/gen.c (genRightShift): fixed bug #870788
3866 * src/SDCCast.c (decorateType): fixed bug #870781
3868 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3870 PIC16 port related changes:
3871 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3872 added variable stackPos,
3874 * gen.c: genCall, assignResultValue: added support for
3875 pushing/retrieving function parameters to/from stack,
3876 genFunction,genEndFunction: setup stack frame for the
3878 genAddrOf: will be changed according to bug 863624
3880 * added files genutils.c and genutils.h which contain gen*
3881 debugged and optimised functions extracted from gen.c
3883 * glue.c: added variable 'externs' which holds extern symbols,
3884 pic16emitRegularMap: is modified to properly handle relocatable
3885 symbols under the new scheme,
3886 pic16createInterruptVect: is modified
3887 pic16printPublics: is modified to emit 'global' assembler directives,
3888 added pic16_printExterns to print extern symbols,
3889 pic16glue: initializes stack/frame pointer in the beginning of
3890 the assembly output. Temporary hack, will be corrected later,
3891 because gplink yet does not support stack and SDCC does not
3892 yet support a type of crt0.o object to create the final binary.
3894 * Removed many lines that contain 8051 legacy code.
3895 * The code is finally placed under a 'code' directive.
3896 * Added port specific options.
3898 * _process_pragma: simplified since now we do not need *special*
3899 include file to define SFR registers. But a separate header
3900 will be needed. This will be developed later.
3901 * _pic16_parseOptions: added, parses port specific options:
3902 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3903 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3904 --preplace-udata-with=
3906 * _pic16_setDefaultOptions: modified to initialize section names,
3907 but hack is temporarly out of order since it needs improvement.
3908 * _pic16_genAssemblerPreamble: configuration words are emitted by
3909 their address instead of their name. This part is incomplete and
3910 supports only the 18Fxx2 devices. Other devices will emit an error
3911 during assembly since they do not contain the same set of config
3913 * _pic16_genIVT: is modified,
3915 * pcode.c: added definitions for some hardware registers that are needed
3917 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3918 All PCI entries are updated. Now LFSR is supported.
3919 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3920 * added pic16_newpCodeOpLit2 to support instructions with
3921 two literal arguments
3922 * pic16_pCode2str: corrected code that emits assembler instructions
3923 with two literal operands and those that have an access bit modifier
3924 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3925 this fixes a bug which caused some labels to be lost, when an
3926 assembler directive was added, i.e. banksel,
3927 * pic16_FixRegisterBanking: improved logic that causes the insertion
3929 * InlineFunction: functions that are called once, are not any more
3930 inlined. This can be a port option in the future,
3932 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3934 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3935 hold the corresponding uninitialized symbols,
3936 * pic16_allocProcessorRegister: registers have explicit marked the
3938 * pic16_allocInternalRegister: registers are explicit marked as
3940 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3941 processing list, so bit registers were lost,
3944 * ralloc.h: added field 'accessBank' and original symbol operand
3945 in register definition,
3946 * removed the field isMapped from register definition,
3948 ** Several functions have been removed from various sources:
3949 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3950 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3951 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3952 pic16_assignRelocatableRegisters
3954 ** others have been introduced:
3955 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3956 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3958 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3960 * support/scripts/inc2h.pl: changed definition of BIT_AT
3961 to emit 'sbit at' instead of 'bit at'. This was a request.
3963 PIC16 port related preliminary changes:
3964 * gen.c: prefixed function popRegFromString with
3965 pic16_ and all references to it corrected
3966 * pcode.c: all pic16_pc_* hardware registers prefixed
3967 with underscore (_),
3968 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3969 * ralloc.c: newReg(): when register is REG_SFR then
3970 set address to rIdx,
3971 pic16_allocProcessorRegister(): marks register wasUsed=0
3972 pic16_writeUsedRegs(): added a call to assign processor
3973 registers via pic16_assignFixedRegisters
3975 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3977 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3978 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3979 variables in unused register banks. Also the SSEG is placed
3980 wherever there is enough space for it, and IDATA can be anywhere
3981 in internal RAM. For now compile using -Wl-Y[stack_size].
3982 The mem file is different for this option as well, since it
3983 makes no sense of talking about DSEG lenght.
3985 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3987 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3988 in certain cases, e.g. when ROM assignment, patch provided
3989 from Albert den Haan.
3991 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5014 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5015 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

5034 A few small changes that speed up the peephole optimizer.
5038 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5040 Try to make the peephole optimizer smarter by maintaining
5041 an association between the assembly source code and the
5042 iCodes that originated them. Put this information to use
5043 with a new peephole rule condition "notVolatile" so that
5044 the rules can be aggressive yet still safe.
5049 * src/mcs51/peeph.def
5051 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5055 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

5059 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5061 Changed the type of the result of the ! (NOT) operator to char;
5062 previously it returned the same type as the source. This allows
5063 us to eliminate all the genFloatNot functions (all of its target
5064 implementations were very buggy) since !float can use the same
5067 * src/SDCCicode.c (ast2iCode): ! returns char

5069 * src/ds390/gen.c (genNot, genNotFloat),
5070 * src/z80/gen.c (genNot, genNotFloat),

5076 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5077 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5078 during interrupts. Ensure WSAVE is located at a shared bank address.
5079 2. Fixed page selection in some places
5080 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5081 the registers name strings.
5082 4. Fixed "signed / unsigned compare" compiler warnings.
5083 5. The PIC port manages its own allocation of the general purpose
5084 registers, but makes no attempt to reuse them. As a result when
5085 compiling it soon runs out of general purpose registers. Some
5086 additional code was added to the files pcode.c and device.c to walk
5087 through the function call tree and rename the registers so that they
5097 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5098 genPlus() & genMinus() when the result is the same as left or right

5104 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5106 Made bitfield a distinct type from bit so that bitfields
5107 convert as per ANSI C and bits retain their traditional
5108 boolean style behaviour. Implemented bitfield support in
5116 * src/ds390/gen.c: bit v bitfield split
5117 * src/z80/gen.c: New support for bitfields
5118 * support/regression/tests/bitfields.c: reenabled z80,
5121 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5123 Rules 246.x, 247.x relate to bitfields, the others speed up
5124 access to xdata mapped I/O devices.
5126 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5128 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5130 Cleaned up genPackBits and genUnpackBits and added two helper
5131 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5132 for literal assignments in genPackBits (thanks to Frieder for
5138 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5140 Fixed bug #748310 (pointer to function type mishandled when the
5141 function name is omitted). Also fixed a SIGSEGV when a function
5142 attribute (reentrant, etc) is used on a non-function or on a
5143 function but misplaced before the parameter list.

5170 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5172 Made the constant following the "interrupt" keyword optional. If
5173 omitted, the function will not automatically be given an entry
5174 in the interrupt vector table (similar to #pragma NOIV, but
5175 less syntacticly kludgy). The interrupt number is also now
5176 range checked. Also fixed a bug in the high order bit example

5679 * src/pic16/pcode.c: Cleaned warnings
5680 * src/pic16/pcodeflow.c: Cleaned warnings
5681 * src/pic16/pcoderegs.c: Cleaned warnings

5697 it can be defined with CFLAGS when running configure
5698 * src/SDCCmain.c: fixed compiling + linking with object files
5700 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5702 * configure.in: configure for pic16 port,
5703 added --disable-pic16-port
5704 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5705 * src/SDCCmain.c: linkOptions is changed to set *,
5706 added if/endif conditional macros to remove options help
5707 messages from optionsTable when a port is not configured, added
5708 support for the PIc16 port in the ports table, when executing
5709 the compiler with no port specified on command line, a default
5710 port is selected with the new macro DEFAULT_PORT which is
5711 defined in port.h, in setDefaultOptions() linkOptions is removed
5712 from initialization assignment, since now it is a set,
5713 parseCmdLine uses setParseWithComma for linkOptions, in
5714 linkEdit() linkOptions are accessed with new function indexSet()
5715 which returns the i'th item of a set variable. See SDCCset.c, in
5716 linkEdit() when calling buildCmdLine(), added linkOptions as
5717 last argument. Now users can pass arguments to gplink via the
5718 -Wl option, main() uses pic16glue() to glue up pic16 programs

5730 * src/pic16/glue.c: commented out some error producing lines
5731 * src/pic16/main.c: __config directives are commented out to stop
5732 gpasm complaining and test the linkage with gplink, _linkCmd and
5733 _asmCmd changed to be more gplink and gpasm friendly
5734 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5735 produced an error when parsed, peep rule 12 is added to utilize
5736 movff, but it is commented out since the pCode does not support
5737 yet a command with 2 address arguments
5739 2003-05-18 <johan AT balder>
5741 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5768 2003-05-11 Borut Razem <borut.razem AT siol.net>
5770 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6780 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6782 2003-01-04 <johan AT balder>
6784 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6786 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6787 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

6799 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6800 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6802 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6804 * in \sdcc\as\mcs51\ changed these files in order to create an
6805 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6806 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6807 following files to include the previous two files: aslink.dsp,
6808 Makefile.aslink, Makefile.bcc, and Makefile.in.
6810 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6811 .adb instead of .cdb
6813 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6815 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6816 value from option --iram-size.
6818 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6820 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6823 2002-09-18 <wiml AT hhhh.org>
6825 * SDCClrange.h: exposed setFromRange() and setToRange()
6826 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6827 packRegsForAccUse() (bug 542397)
6828 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6829 multiple times and emitting the fetch operations more than once
6830 added aopGetUsesAcc() function to allow binary operators to
6831 fetch their operands in the correct order; made genMinus() emit
6832 compact code for X = LITERAL - Y
6834 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6835 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6836 sprintf() in line 1267.
6838 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6839 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6842 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6843 Changes to aslink (All the changes are marked with 'JCF'):
6845 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6848 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6849 area BSEG. Also moves, if possible, the DATA area down into the internal
6850 ram so more space is available.
6852 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6855 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6856 not bytes. Function summary() which creates a memory usage summary
6857 file with extension .mem. Reports of overlaping stack and small stack
6858 size. If the space for the stack is less than 16 bytes aslink trows a
6861 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6862 the 8051. Option 'y' for memory summary output file.
6864 Changes to sdcc (All the changes are marked with 'JCF'):
6866 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6868 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6869 overlaying area for it (uses RegBankUsed[4]).
6871 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6872 bank zero as used by default. By default aslink locates the stack
6873 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6874 the creation of the .mem file. Delegates the allocation of data area
6875 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6876 the begining of the stack area to aslink.
6878 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6879 glue() in SDCCglue.c creates an area for it.
6881 2002-09-03 Borut Razem <borut.razem AT siol.net>
6882 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6883 sdcc/src/pic/glue.c:
6884 introduced atexit() handler for teporay files removal in case of
6885 errors, assertions, ...
6887 2002-08-29 Borut Razem <borut.razem AT siol.net>
6888 * sdcc/support/cpp2/auto-host_vc_in.h:
6889 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6890 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6891 Maybe there is a similar problem with BORLANDC? It should be checked!
6893 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6894 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6895 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6896 was not executed, and the compiler (cl) launched a warning:
6897 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6899 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6900 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6902 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6903 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6905 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6906 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6909 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6910 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6911 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6912 - added Release configuration in VS projects
6913 - review of compiler an linker options
6914 - VC .exe files are generated in bin_vc directory, not to interfere
6915 with binaries generated from other projects (cygwin, mingw, bcc ...)
6917 * sdcc/src/yacc.dsp: added
6919 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6920 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6921 and insert the version number definitions from .version
6923 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6925 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6926 added - genarate auto-host.h using auto-host_vc_in.h as template
6929 removed from CVS, generated automatically
6931 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6932 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6934 2002-08-11 Borut Razem <borut.razem AT siol.net>
6935 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6937 2002-08-10 Borut Razem <borut.razem AT siol.net>
6938 * src/SDCCmain.c (main):
6939 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6940 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6941 The consequence was that some temporary files were not removed.
6944 unification of code in functions tempfilename() and tempfile():
6945 function tempnam() is defined in Visual Studio 6.0 and .NET
6947 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6949 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6950 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6951 - removed compiler command line option /WX: Treats all warnings as errors
6952 - update a list of source files, included into the project
6954 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6955 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6956 changed project type to Generic Project so that can be correcly converted to VS.NET project
6958 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6960 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6962 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

6968 added newline in the def file to keep MSC compiler satisfied
6970 * sdcc/src/z80/gen.c:
6971 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6972 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6973 - solved MSC error in function aopDump()

7152 * sdcc/src/SDCCloop.c:
7153 Previous fix was not good. basic blocks that have "break" or "return" are
7154 not really partof a loop , but live ranges used in these blocks should
7155 be live thru the entire loop, so set partOfLoop but don't add them to
