459 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
461 Adding support for replacing ljmps with sjmps in jumptables
462 generated for switch statements. For now you need to set the
463 environment variable SDCC_SJMP_JUMPTABLE to enable this.
464 Now 4 algorithms for mcs51 jumptable generation are used:
465 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
466 addresses loaded pc-relative for up to 112 cases and stack-pushing
467 target addresses loaded with offset from dptr for up to 256 cases.
469 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
470 * src/mcs51/main.c: adapted constants for switch table generation
471 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

493 Large cummulative patch for pic16 port.
494 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
495 to call when a stack overflow occurs,
496 * (malloc.h): added CVS Id tag,
497 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
499 * added libc directory. The current version of LibC contains string
500 functions, ctype functions and macros and some functions of the
501 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
502 be extensively tested in the future. Standard disclaimer here.
503 Library is not automatically build yet. But one can build it by
504 invoking 'make' inside the libc directory.
505 * added ADC library under libio. Preliminary version yet.
507 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
508 * src/pic16/gen.c (aopForRemat): asmop size is filled by
509 aopForRemat() now and not by pic16_aopOp(),

515 * (pic16_storeForReturn): optimized return of 0,
516 * (genCmp): experimental code for new genCmp which uses PIC18's
517 special compare&skip instructions. Initial tests fail some times
518 with variables grater than 1 byte in size, so new code is disabled,
519 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
521 * (genCast): began a fix to optimize the casting of a bit to another
522 bit, now assigning a bitfield to another bitfield will fail, sorry,
523 * src/pic16/main.c: disabled the use of lr-support feature,
524 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
525 * added some function prototypes, added function _debugf prototype,
526 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
527 bits with offset (case PO_GPR_BIT),
528 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
530 * (isBankInstruction): modified to return 0 for no banking instruction,
531 and 1 for banking instruction,
532 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
533 caused stop processing pCodes after a inline assembly block,
534 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
535 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
536 registers when it shouldn't,
537 * src/pic16/ralloc.c (allocReg): add preliminary support for
538 supporting a limited set of temporary registers,
540 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
542 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
543 genDataPointerSet): ensure assignments always copy in MSB to LSB
545 (loadRegFromAop): recognize CLRH optimization,
546 (genFunction): optimize RECEIVE iCodes in reentrant functions
548 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
550 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
551 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
553 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3545 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3547 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3548 loaded with the linker search paths (-L arguments) and the libraries
3549 to be linked with the current source (-l arguments). Changes
3550 currently will affect only the pic16 port.
3551 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3552 include path the port specific paths and port specific libraries,
3553 * gplink command now contains the $3 argument,
3554 * src/pic16/device.h,
3555 * src/pic16/device.c,: structure PIC_device is made public and
3556 renamed to PIC16_device, the same for variable Pics which is renamed

3571 Documenting changes from previous commits.
3572 * configure.in (version 1.56),
3573 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3574 when generating output files to configure the pic16 library,
3575 but now I've commented it out, since gputils aren't installed in the
3576 SF compile farm, so library won't compile
3578 * device/lib/Makefile.in (version 1.56): initially I've added in
3579 target 'all' the prerequestive 'model-pic16' so it compiled the
3580 pic16 library, but now I've commented it out for the same reasons
3582 * added targets 'model-pic16' and 'objects-pic16' to compile the
3584 * added target 'port-specific-objects-pic16' to handle the
3585 generated libraries and copy them into the build/ directory
3586 * added target 'clean-intermediate-pic16' to clean intermediate
3587 files into pic16 directory

3609 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3610 option so that it actually works. Made it specific to the z80, since
3611 the gbz80 doesn't have these kinds of I/O ports.
3613 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3615 * device/include/z180.h,

3639 via literal number. The symbol is placed in the corresponding
3640 position of the data ram
3641 * (pic16_dump_section): relocatable and absolute uninitialized
3642 data are now emitted in sorted order to reduce section naming,
3643 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3644 weren't marked as being in the access bank,
3646 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3648 Added portion of GNU PIC Library under the directory
3649 device/include/pic16 and device/lib/pic16. These files
3650 contain the declarations of SFRs for the PIC18Fxx2 devices.
3651 The directory is initialized via configure from toplevel.
3653 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3655 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3681 all over. Telling LaTeX to be less strict with word spacing
3682 to better keep the right margin. Changed some notes about
3683 maintainance of the ports in section 3.2.1 - is it OK like this?
3685 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3723 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3725 * src/pic16/peeph.def: all peepholes with movff are commented out,
3726 because there is a problem in the pcode peep optimizer,
3727 * src/pic16/ralloc.c: the register allocator can now reuse local

3729 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3731 Added file src/pic16/NOTES with information about program writing on
3732 the current port version.

3764 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3767 * src/z80/main.c: added missed needLinkerScript flags (more than
3768 one port structure defined in these file)
3769 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3791 * (pic14emitOverlay): modified to emit a commented overlay segment
3792 directive when no overlay data exist
3793 * (picglue): modified to emit uninitialized data segment
3794 according to udata_section_name

3804 2004-01-07 Borut Razem <borut.razem AT siol.net>
3806 * support/scripts/sdcc.nsi: update PATH
3807 * support/scripts/sdcc.ico: craeted

3820 include information about variables allocated to the overlay
3823 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3825 * as/mcs51/lkmain.c: Help about -Y option

3837 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3839 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3840 (default behaviour).
3842 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3844 A python script to validate compiler diagnostic messages. It can be
3845 used to verify that sdcc complains about bad c source code and
3846 gives a good location of the error.
3847 * support/valdiag/Makefile,
3848 * support/valdiag/valdiag.py,
3849 * support/valdiag/tests/*
3851 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3853 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3864 * src/common.h: added ifndef/define/endif macros
3865 around the header file.
3866 Bug reported from Jesus Calvino-Fraga
3868 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3870 * sdcc.spec: updated
3871 * device/include/Makefile.in: don't install CVS directories
3872 * device/lib/Makefile.in: added removal of CVS directories after install
3873 * doc/Makefile: fixed install, added local_icons
3874 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3875 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3876 * src/ds390/gen.c (genRightShift): fixed bug #870788
3877 * src/SDCCast.c (decorateType): fixed bug #870781
3879 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3881 PIC16 port related changes:
3882 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3883 added variable stackPos,
3885 * gen.c: genCall, assignResultValue: added support for
3886 pushing/retrieving function parameters to/from stack,
3887 genFunction,genEndFunction: setup stack frame for the
3889 genAddrOf: will be changed according to bug 863624
3891 * added files genutils.c and genutils.h which contain gen*
3892 debugged and optimised functions extracted from gen.c
3894 * glue.c: added variable 'externs' which holds extern symbols,
3895 pic16emitRegularMap: is modified to properly handle relocatable
3896 symbols under the new scheme,
3897 pic16createInterruptVect: is modified
3898 pic16printPublics: is modified to emit 'global' assembler directives,
3899 added pic16_printExterns to print extern symbols,
3900 pic16glue: initializes stack/frame pointer in the beginning of
3901 the assembly output. Temporary hack, will be corrected later,
3902 because gplink yet does not support stack and SDCC does not
3903 yet support a type of crt0.o object to create the final binary.
3905 * Removed many lines that contain 8051 legacy code.
3906 * The code is finally placed under a 'code' directive.
3907 * Added port specific options.
3909 * _process_pragma: simplified since now we do not need *special*
3910 include file to define SFR registers. But a separate header
3911 will be needed. This will be developed later.
3912 * _pic16_parseOptions: added, parses port specific options:
3913 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3914 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3915 --preplace-udata-with=
3917 * _pic16_setDefaultOptions: modified to initialize section names,
3918 but hack is temporarly out of order since it needs improvement.
3919 * _pic16_genAssemblerPreamble: configuration words are emitted by
3920 their address instead of their name. This part is incomplete and
3921 supports only the 18Fxx2 devices. Other devices will emit an error
3922 during assembly since they do not contain the same set of config
3924 * _pic16_genIVT: is modified,
3926 * pcode.c: added definitions for some hardware registers that are needed
3928 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3929 All PCI entries are updated. Now LFSR is supported.
3930 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3931 * added pic16_newpCodeOpLit2 to support instructions with
3932 two literal arguments
3933 * pic16_pCode2str: corrected code that emits assembler instructions
3934 with two literal operands and those that have an access bit modifier
3935 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3936 this fixes a bug which caused some labels to be lost, when an
3937 assembler directive was added, i.e. banksel,
3938 * pic16_FixRegisterBanking: improved logic that causes the insertion
3940 * InlineFunction: functions that are called once, are not any more
3941 inlined. This can be a port option in the future,
3943 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3945 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3946 hold the corresponding uninitialized symbols,
3947 * pic16_allocProcessorRegister: registers have explicit marked the
3949 * pic16_allocInternalRegister: registers are explicit marked as
3951 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3952 processing list, so bit registers were lost,
3955 * ralloc.h: added field 'accessBank' and original symbol operand
3956 in register definition,
3957 * removed the field isMapped from register definition,
3959 ** Several functions have been removed from various sources:
3960 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3961 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3962 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3963 pic16_assignRelocatableRegisters
3965 ** others have been introduced:
3966 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3967 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3969 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3971 * support/scripts/inc2h.pl: changed definition of BIT_AT
3972 to emit 'sbit at' instead of 'bit at'. This was a request.
3974 PIC16 port related preliminary changes:
3975 * gen.c: prefixed function popRegFromString with
3976 pic16_ and all references to it corrected
3977 * pcode.c: all pic16_pc_* hardware registers prefixed
3978 with underscore (_),
3979 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3980 * ralloc.c: newReg(): when register is REG_SFR then
3981 set address to rIdx,
3982 pic16_allocProcessorRegister(): marks register wasUsed=0
3983 pic16_writeUsedRegs(): added a call to assign processor
3984 registers via pic16_assignFixedRegisters
3986 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3988 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3989 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3990 variables in unused register banks. Also the SSEG is placed
3991 wherever there is enough space for it, and IDATA can be anywhere
3992 in internal RAM. For now compile using -Wl-Y[stack_size].
3993 The mem file is different for this option as well, since it
3994 makes no sense of talking about DSEG lenght.
3996 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3998 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3999 in certain cases, e.g. when ROM assignment, patch provided
4000 from Albert den Haan.
4002 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4549 Fixed a number of problems revealed by bug #827883.
4550 * src/SDCCloop.c (loopInvariants): Spill location of the
4551 result operand should be recomputed if extracted from

4555 not occur if the control variable is involved with a
4556 relational operator.

5045 A few small changes that speed up the peephole optimizer.
5049 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5051 Try to make the peephole optimizer smarter by maintaining
5052 an association between the assembly source code and the
5053 iCodes that originated them. Put this information to use
5054 with a new peephole rule condition "notVolatile" so that
5055 the rules can be aggressive yet still safe.

5074 us to eliminate all the genFloatNot functions (all of its target
5075 implementations were very buggy) since !float can use the same

5087 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5088 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5089 during interrupts. Ensure WSAVE is located at a shared bank address.
5090 2. Fixed page selection in some places
5091 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5092 the registers name strings.
5093 4. Fixed "signed / unsigned compare" compiler warnings.
5094 5. The PIC port manages its own allocation of the general purpose
5095 registers, but makes no attempt to reuse them. As a result when
5096 compiling it soon runs out of general purpose registers. Some
5097 additional code was added to the files pcode.c and device.c to walk
5098 through the function call tree and rename the registers so that they
5108 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5115 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5117 Made bitfield a distinct type from bit so that bitfields
5118 convert as per ANSI C and bits retain their traditional
5119 boolean style behaviour. Implemented bitfield support in
5127 * src/ds390/gen.c: bit v bitfield split
5128 * src/z80/gen.c: New support for bitfields
5129 * support/regression/tests/bitfields.c: reenabled z80,
5132 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5134 Rules 246.x, 247.x relate to bitfields, the others speed up
5135 access to xdata mapped I/O devices.
5137 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5139 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5141 Cleaned up genPackBits and genUnpackBits and added two helper
5142 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5143 for literal assignments in genPackBits (thanks to Frieder for
5149 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5151 Fixed bug #748310 (pointer to function type mishandled when the
5152 function name is omitted). Also fixed a SIGSEGV when a function
5153 attribute (reentrant, etc) is used on a non-function or on a
5154 function but misplaced before the parameter list.

5181 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5183 Made the constant following the "interrupt" keyword optional. If
5184 omitted, the function will not automatically be given an entry
5185 in the interrupt vector table (similar to #pragma NOIV, but
5186 less syntacticly kludgy). The interrupt number is also now
5187 range checked. Also fixed a bug in the high order bit example

5663 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5664 the regression tests I'm not brave enough to enable 245.b, 245.c
5665 * doc/sdccman.lyx: added latex preamble for hyperref package.
5666 Using pdflatex this will give you a hyperlinked pdf file with

5690 * src/pic16/pcode.c: Cleaned warnings
5691 * src/pic16/pcodeflow.c: Cleaned warnings
5692 * src/pic16/pcoderegs.c: Cleaned warnings

5708 it can be defined with CFLAGS when running configure
5709 * src/SDCCmain.c: fixed compiling + linking with object files
5711 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5713 * configure.in: configure for pic16 port,
5714 added --disable-pic16-port
5715 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5716 * src/SDCCmain.c: linkOptions is changed to set *,
5717 added if/endif conditional macros to remove options help
5718 messages from optionsTable when a port is not configured, added
5719 support for the PIc16 port in the ports table, when executing
5720 the compiler with no port specified on command line, a default
5721 port is selected with the new macro DEFAULT_PORT which is
5722 defined in port.h, in setDefaultOptions() linkOptions is removed
5723 from initialization assignment, since now it is a set,
5724 parseCmdLine uses setParseWithComma for linkOptions, in
5725 linkEdit() linkOptions are accessed with new function indexSet()
5726 which returns the i'th item of a set variable. See SDCCset.c, in
5727 linkEdit() when calling buildCmdLine(), added linkOptions as
5728 last argument. Now users can pass arguments to gplink via the
5729 -Wl option, main() uses pic16glue() to glue up pic16 programs
5730 * src/SDCCpeeph.c: various changes to support pic16

5741 * src/pic16/glue.c: commented out some error producing lines
5742 * src/pic16/main.c: __config directives are commented out to stop
5743 gpasm complaining and test the linkage with gplink, _linkCmd and
5744 _asmCmd changed to be more gplink and gpasm friendly
5745 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5746 produced an error when parsed, peep rule 12 is added to utilize
5747 movff, but it is commented out since the pCode does not support
5748 yet a command with 2 address arguments
5750 2003-05-18 <johan AT balder>
5752 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5777 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5779 2003-05-11 Borut Razem <borut.razem AT siol.net>
5781 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5782 the path of bin directory, so that PATH is the only env. variable, which has to be set
5783 in case of standard installation.
5784 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6791 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6793 2003-01-04 <johan AT balder>
6795 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6797 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6810 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6811 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6813 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6815 * in \sdcc\as\mcs51\ changed these files in order to create an
6816 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6817 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6818 following files to include the previous two files: aslink.dsp,
6819 Makefile.aslink, Makefile.bcc, and Makefile.in.
6821 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6822 .adb instead of .cdb
6824 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6826 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6827 value from option --iram-size.
6829 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6831 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6834 2002-09-18 <wiml AT hhhh.org>
6836 * SDCClrange.h: exposed setFromRange() and setToRange()
6837 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6838 packRegsForAccUse() (bug 542397)
6839 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6840 multiple times and emitting the fetch operations more than once
6841 added aopGetUsesAcc() function to allow binary operators to
6842 fetch their operands in the correct order; made genMinus() emit
6843 compact code for X = LITERAL - Y
6845 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6846 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6847 sprintf() in line 1267.
6849 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6850 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6853 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6854 Changes to aslink (All the changes are marked with 'JCF'):
6856 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6859 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6860 area BSEG. Also moves, if possible, the DATA area down into the internal
6861 ram so more space is available.
6863 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6866 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6867 not bytes. Function summary() which creates a memory usage summary
6868 file with extension .mem. Reports of overlaping stack and small stack
6869 size. If the space for the stack is less than 16 bytes aslink trows a
6872 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6873 the 8051. Option 'y' for memory summary output file.
6875 Changes to sdcc (All the changes are marked with 'JCF'):
6877 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6879 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6880 overlaying area for it (uses RegBankUsed[4]).
6882 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6883 bank zero as used by default. By default aslink locates the stack
6884 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6885 the creation of the .mem file. Delegates the allocation of data area
6886 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6887 the begining of the stack area to aslink.
6889 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6890 glue() in SDCCglue.c creates an area for it.
6892 2002-09-03 Borut Razem <borut.razem AT siol.net>
6893 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6894 sdcc/src/pic/glue.c:
6895 introduced atexit() handler for teporay files removal in case of
6896 errors, assertions, ...
6898 2002-08-29 Borut Razem <borut.razem AT siol.net>
6899 * sdcc/support/cpp2/auto-host_vc_in.h:
6900 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6901 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6902 Maybe there is a similar problem with BORLANDC? It should be checked!
6904 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6905 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6906 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6907 was not executed, and the compiler (cl) launched a warning:
6908 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6910 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6911 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6913 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6914 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6916 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6917 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6920 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6921 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6922 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6923 - added Release configuration in VS projects
6924 - review of compiler an linker options
6925 - VC .exe files are generated in bin_vc directory, not to interfere
6926 with binaries generated from other projects (cygwin, mingw, bcc ...)
6928 * sdcc/src/yacc.dsp: added
6930 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6931 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6932 and insert the version number definitions from .version
6934 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6936 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6937 added - genarate auto-host.h using auto-host_vc_in.h as template
6940 removed from CVS, generated automatically
6942 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6943 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6945 2002-08-11 Borut Razem <borut.razem AT siol.net>
6946 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6948 2002-08-10 Borut Razem <borut.razem AT siol.net>
6949 * src/SDCCmain.c (main):
6950 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6951 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6952 The consequence was that some temporary files were not removed.
6955 unification of code in functions tempfilename() and tempfile():
6956 function tempnam() is defined in Visual Studio 6.0 and .NET
6958 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6960 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6961 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6962 - removed compiler command line option /WX: Treats all warnings as errors
6963 - update a list of source files, included into the project
6965 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6966 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
