452 (setFromConditionArgs): friendly operand parser for peephole rules,
453 (operandBaseName, operandsNotRelated): new peephole condition
454 "operandsNotRelated" -- similar to "operandsNotSame", but takes
455 architecture specific register naming into account, handles n-way
456 comparisons, and supports quoted literals
457 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
459 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

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

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

523 * (pic16_storeForReturn): optimized return of 0,
524 * (genCmp): experimental code for new genCmp which uses PIC18's
525 special compare&skip instructions. Initial tests fail some times
526 with variables grater than 1 byte in size, so new code is disabled,
527 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
529 * (genCast): began a fix to optimize the casting of a bit to another
530 bit, now assigning a bitfield to another bitfield will fail, sorry,
531 * src/pic16/main.c: disabled the use of lr-support feature,
532 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
533 * added some function prototypes, added function _debugf prototype,

535 bits with offset (case PO_GPR_BIT),
536 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
538 * (isBankInstruction): modified to return 0 for no banking instruction,
539 and 1 for banking instruction,
540 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
541 caused stop processing pCodes after a inline assembly block,
542 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
543 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
544 registers when it shouldn't,
545 * src/pic16/ralloc.c (allocReg): add preliminary support for
546 supporting a limited set of temporary registers,
548 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
550 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
551 genDataPointerSet): ensure assignments always copy in MSB to LSB
553 (loadRegFromAop): recognize CLRH optimization,
554 (genFunction): optimize RECEIVE iCodes in reentrant functions
556 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
558 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
559 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
561 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3556 loaded with the linker search paths (-L arguments) and the libraries
3557 to be linked with the current source (-l arguments). Changes
3558 currently will affect only the pic16 port.
3559 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3560 include path the port specific paths and port specific libraries,
3561 * gplink command now contains the $3 argument,

3579 Documenting changes from previous commits.
3580 * configure.in (version 1.56),
3581 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3582 when generating output files to configure the pic16 library,
3583 but now I've commented it out, since gputils aren't installed in the
3584 SF compile farm, so library won't compile
3586 * device/lib/Makefile.in (version 1.56): initially I've added in
3587 target 'all' the prerequestive 'model-pic16' so it compiled the
3588 pic16 library, but now I've commented it out for the same reasons
3590 * added targets 'model-pic16' and 'objects-pic16' to compile the
3592 * added target 'port-specific-objects-pic16' to handle the
3593 generated libraries and copy them into the build/ directory
3594 * added target 'clean-intermediate-pic16' to clean intermediate
3595 files into pic16 directory
3596 * in target 'installdirs' added line to create directory pic16 in
3597 the installation path
3599 * device/include/Makefile.in (version 1.11): in target 'install'
3600 added lines to copy all header files to installation path,
3601 * in target 'installdirs' added line create directory for pic16
3602 headers in the installation path
3604 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3617 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3618 option so that it actually works. Made it specific to the z80, since
3619 the gbz80 doesn't have these kinds of I/O ports.
3621 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3623 * device/include/z180.h,

3631 * src/z80/main.c (_process_pragma): add support for pragmas bank and
3632 portmode; added deprecation warning for bank= and protmode= forms.
3633 Also, guard against buffer overflow.
3634 * src/z80/gen.c (aopGet): generate better code for sfr banked read
3636 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3638 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3639 changed interrupt vector table generation to only emit declared vectors.

3645 Mainly changes to support compilation of the device libraries
3646 * src/pic16/device.c: stack is allocated via symbol and not
3647 via literal number. The symbol is placed in the corresponding
3648 position of the data ram
3649 * (pic16_dump_section): relocatable and absolute uninitialized
3650 data are now emitted in sorted order to reduce section naming,
3651 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3652 weren't marked as being in the access bank,
3654 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3656 Added portion of GNU PIC Library under the directory
3657 device/include/pic16 and device/lib/pic16. These files
3658 contain the declarations of SFRs for the PIC18Fxx2 devices.
3659 The directory is initialized via configure from toplevel.
3661 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3663 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3664 the spilllocations to be compared correctly

3688 * doc/sdccman.lyx: Moved and added some sections, small changes
3689 all over. Telling LaTeX to be less strict with word spacing
3690 to better keep the right margin. Changed some notes about
3691 maintainance of the ports in section 3.2.1 - is it OK like this?
3693 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3730 UPPER for immediate operands,
3731 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3733 * src/pic16/peeph.def: all peepholes with movff are commented out,
3734 because there is a problem in the pcode peep optimizer,
3735 * src/pic16/ralloc.c: the register allocator can now reuse local

3737 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3739 Added file src/pic16/NOTES with information about program writing on
3740 the current port version.

3793 needLinkerScript flag
3795 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3796 * src/pic/glue.c: added variable udata_section_name to
3797 override default uninitialized data segment definition for

3799 * (pic14emitOverlay): modified to emit a commented overlay segment
3800 directive when no overlay data exist
3801 * (picglue): modified to emit uninitialized data segment
3802 according to udata_section_name

3845 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3847 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3848 (default behaviour).
3850 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3852 A python script to validate compiler diagnostic messages. It can be
3853 used to verify that sdcc complains about bad c source code and
3854 gives a good location of the error.
3855 * support/valdiag/Makefile,
3856 * support/valdiag/valdiag.py,
3857 * support/valdiag/tests/*

3874 Bug reported from Jesus Calvino-Fraga
3876 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3878 * sdcc.spec: updated
3879 * device/include/Makefile.in: don't install CVS directories
3880 * device/lib/Makefile.in: added removal of CVS directories after install
3881 * doc/Makefile: fixed install, added local_icons
3882 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3883 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3884 * src/ds390/gen.c (genRightShift): fixed bug #870788
3885 * src/SDCCast.c (decorateType): fixed bug #870781
3887 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3889 PIC16 port related changes:
3890 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3891 added variable stackPos,
3893 * gen.c: genCall, assignResultValue: added support for
3894 pushing/retrieving function parameters to/from stack,
3895 genFunction,genEndFunction: setup stack frame for the
3897 genAddrOf: will be changed according to bug 863624
3899 * added files genutils.c and genutils.h which contain gen*
3900 debugged and optimised functions extracted from gen.c
3902 * glue.c: added variable 'externs' which holds extern symbols,
3903 pic16emitRegularMap: is modified to properly handle relocatable
3904 symbols under the new scheme,
3905 pic16createInterruptVect: is modified
3906 pic16printPublics: is modified to emit 'global' assembler directives,
3907 added pic16_printExterns to print extern symbols,
3908 pic16glue: initializes stack/frame pointer in the beginning of
3909 the assembly output. Temporary hack, will be corrected later,
3910 because gplink yet does not support stack and SDCC does not
3911 yet support a type of crt0.o object to create the final binary.
3913 * Removed many lines that contain 8051 legacy code.
3914 * The code is finally placed under a 'code' directive.
3915 * Added port specific options.
3917 * _process_pragma: simplified since now we do not need *special*
3918 include file to define SFR registers. But a separate header
3919 will be needed. This will be developed later.
3920 * _pic16_parseOptions: added, parses port specific options:
3921 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3922 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3923 --preplace-udata-with=
3925 * _pic16_setDefaultOptions: modified to initialize section names,
3926 but hack is temporarly out of order since it needs improvement.
3927 * _pic16_genAssemblerPreamble: configuration words are emitted by
3928 their address instead of their name. This part is incomplete and
3929 supports only the 18Fxx2 devices. Other devices will emit an error
3930 during assembly since they do not contain the same set of config
3932 * _pic16_genIVT: is modified,
3934 * pcode.c: added definitions for some hardware registers that are needed
3936 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3937 All PCI entries are updated. Now LFSR is supported.
3938 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3939 * added pic16_newpCodeOpLit2 to support instructions with
3940 two literal arguments
3941 * pic16_pCode2str: corrected code that emits assembler instructions
3942 with two literal operands and those that have an access bit modifier
3943 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3944 this fixes a bug which caused some labels to be lost, when an
3945 assembler directive was added, i.e. banksel,
3946 * pic16_FixRegisterBanking: improved logic that causes the insertion
3948 * InlineFunction: functions that are called once, are not any more
3949 inlined. This can be a port option in the future,
3951 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3953 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3954 hold the corresponding uninitialized symbols,
3955 * pic16_allocProcessorRegister: registers have explicit marked the
3957 * pic16_allocInternalRegister: registers are explicit marked as
3959 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3960 processing list, so bit registers were lost,
3963 * ralloc.h: added field 'accessBank' and original symbol operand
3964 in register definition,
3965 * removed the field isMapped from register definition,
3967 ** Several functions have been removed from various sources:
3968 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3969 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3970 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3971 pic16_assignRelocatableRegisters
3973 ** others have been introduced:
3974 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3975 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3977 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3979 * support/scripts/inc2h.pl: changed definition of BIT_AT
3980 to emit 'sbit at' instead of 'bit at'. This was a request.
3982 PIC16 port related preliminary changes:
3983 * gen.c: prefixed function popRegFromString with
3984 pic16_ and all references to it corrected
3985 * pcode.c: all pic16_pc_* hardware registers prefixed
3986 with underscore (_),
3987 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3988 * ralloc.c: newReg(): when register is REG_SFR then
3989 set address to rIdx,
3990 pic16_allocProcessorRegister(): marks register wasUsed=0
3991 pic16_writeUsedRegs(): added a call to assign processor
3992 registers via pic16_assignFixedRegisters
3994 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3996 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3997 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3998 variables in unused register banks. Also the SSEG is placed
3999 wherever there is enough space for it, and IDATA can be anywhere
4000 in internal RAM. For now compile using -Wl-Y[stack_size].
4001 The mem file is different for this option as well, since it
4002 makes no sense of talking about DSEG lenght.
4004 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4006 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4007 in certain cases, e.g. when ROM assignment, patch provided
4008 from Albert den Haan.
4010 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5053 A few small changes that speed up the peephole optimizer.
5057 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5059 Try to make the peephole optimizer smarter by maintaining
5060 an association between the assembly source code and the
5061 iCodes that originated them. Put this information to use
5062 with a new peephole rule condition "notVolatile" so that

5068 * src/mcs51/peeph.def
5070 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5074 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5075 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5076 if the left or right operand symbols have the accuse flag set.
5078 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5080 Changed the type of the result of the ! (NOT) operator to char;
5081 previously it returned the same type as the source. This allows
5082 us to eliminate all the genFloatNot functions (all of its target
5083 implementations were very buggy) since !float can use the same
5086 * src/SDCCicode.c (ast2iCode): ! returns char

5095 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5096 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5097 during interrupts. Ensure WSAVE is located at a shared bank address.
5098 2. Fixed page selection in some places
5099 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5100 the registers name strings.
5101 4. Fixed "signed / unsigned compare" compiler warnings.
5102 5. The PIC port manages its own allocation of the general purpose
5103 registers, but makes no attempt to reuse them. As a result when
5104 compiling it soon runs out of general purpose registers. Some
5105 additional code was added to the files pcode.c and device.c to walk
5106 through the function call tree and rename the registers so that they
5116 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5123 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5125 Made bitfield a distinct type from bit so that bitfields
5126 convert as per ANSI C and bits retain their traditional
5127 boolean style behaviour. Implemented bitfield support in
5135 * src/ds390/gen.c: bit v bitfield split
5136 * src/z80/gen.c: New support for bitfields
5137 * support/regression/tests/bitfields.c: reenabled z80,
5140 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5142 Rules 246.x, 247.x relate to bitfields, the others speed up
5143 access to xdata mapped I/O devices.
5145 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5147 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5149 Cleaned up genPackBits and genUnpackBits and added two helper
5150 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5151 for literal assignments in genPackBits (thanks to Frieder for
5157 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5159 Fixed bug #748310 (pointer to function type mishandled when the
5160 function name is omitted). Also fixed a SIGSEGV when a function
5161 attribute (reentrant, etc) is used on a non-function or on a
5162 function but misplaced before the parameter list.

5189 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5191 Made the constant following the "interrupt" keyword optional. If
5192 omitted, the function will not automatically be given an entry
5193 in the interrupt vector table (similar to #pragma NOIV, but
5194 less syntacticly kludgy). The interrupt number is also now
5195 range checked. Also fixed a bug in the high order bit example

5664 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5665 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5666 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

5671 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5672 the regression tests I'm not brave enough to enable 245.b, 245.c
5673 * doc/sdccman.lyx: added latex preamble for hyperref package.
5674 Using pdflatex this will give you a hyperlinked pdf file with
5675 bookmarks. (prepend '%' before /usepackage if this breaks something)

5722 added --disable-pic16-port
5723 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5724 * src/SDCCmain.c: linkOptions is changed to set *,
5725 added if/endif conditional macros to remove options help
5726 messages from optionsTable when a port is not configured, added
5727 support for the PIc16 port in the ports table, when executing
5728 the compiler with no port specified on command line, a default
5729 port is selected with the new macro DEFAULT_PORT which is
5730 defined in port.h, in setDefaultOptions() linkOptions is removed
5731 from initialization assignment, since now it is a set,
5732 parseCmdLine uses setParseWithComma for linkOptions, in
5733 linkEdit() linkOptions are accessed with new function indexSet()
5734 which returns the i'th item of a set variable. See SDCCset.c, in
5735 linkEdit() when calling buildCmdLine(), added linkOptions as
5736 last argument. Now users can pass arguments to gplink via the
5737 -Wl option, main() uses pic16glue() to glue up pic16 programs

5749 * src/pic16/glue.c: commented out some error producing lines
5750 * src/pic16/main.c: __config directives are commented out to stop
5751 gpasm complaining and test the linkage with gplink, _linkCmd and
5752 _asmCmd changed to be more gplink and gpasm friendly
5753 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5754 produced an error when parsed, peep rule 12 is added to utilize
5755 movff, but it is commented out since the pCode does not support
5756 yet a command with 2 address arguments
5758 2003-05-18 <johan AT balder>
5760 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5785 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5787 2003-05-11 Borut Razem <borut.razem AT siol.net>
5789 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5790 the path of bin directory, so that PATH is the only env. variable, which has to be set
5791 in case of standard installation.
5792 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6795 * src/SDCCicode.c: fixed array add
6797 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6798 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6799 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6801 2003-01-04 <johan AT balder>
6803 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6805 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6818 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6819 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6821 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6823 * in \sdcc\as\mcs51\ changed these files in order to create an
6824 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6825 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6826 following files to include the previous two files: aslink.dsp,
6827 Makefile.aslink, Makefile.bcc, and Makefile.in.
6829 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6830 .adb instead of .cdb
6832 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6834 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6835 value from option --iram-size.
6837 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6839 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6842 2002-09-18 <wiml AT hhhh.org>
6844 * SDCClrange.h: exposed setFromRange() and setToRange()
6845 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6846 packRegsForAccUse() (bug 542397)
6847 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6848 multiple times and emitting the fetch operations more than once
6849 added aopGetUsesAcc() function to allow binary operators to
6850 fetch their operands in the correct order; made genMinus() emit
6851 compact code for X = LITERAL - Y
6853 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6854 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6855 sprintf() in line 1267.
6857 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6858 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6861 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6862 Changes to aslink (All the changes are marked with 'JCF'):
6864 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6867 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6868 area BSEG. Also moves, if possible, the DATA area down into the internal
6869 ram so more space is available.
6871 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6874 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6875 not bytes. Function summary() which creates a memory usage summary
6876 file with extension .mem. Reports of overlaping stack and small stack
6877 size. If the space for the stack is less than 16 bytes aslink trows a
6880 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6881 the 8051. Option 'y' for memory summary output file.
6883 Changes to sdcc (All the changes are marked with 'JCF'):
6885 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6887 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6888 overlaying area for it (uses RegBankUsed[4]).
6890 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6891 bank zero as used by default. By default aslink locates the stack
6892 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6893 the creation of the .mem file. Delegates the allocation of data area
6894 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6895 the begining of the stack area to aslink.
6897 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6898 glue() in SDCCglue.c creates an area for it.
6900 2002-09-03 Borut Razem <borut.razem AT siol.net>
6901 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6902 sdcc/src/pic/glue.c:
6903 introduced atexit() handler for teporay files removal in case of
6904 errors, assertions, ...
6906 2002-08-29 Borut Razem <borut.razem AT siol.net>
6907 * sdcc/support/cpp2/auto-host_vc_in.h:
6908 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6909 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6910 Maybe there is a similar problem with BORLANDC? It should be checked!
6912 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6913 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6914 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6915 was not executed, and the compiler (cl) launched a warning:
6916 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6918 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6919 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6921 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6922 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6924 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6925 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6927 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6928 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6929 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6930 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6931 - added Release configuration in VS projects
6932 - review of compiler an linker options
6933 - VC .exe files are generated in bin_vc directory, not to interfere
6934 with binaries generated from other projects (cygwin, mingw, bcc ...)
6936 * sdcc/src/yacc.dsp: added
6938 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6939 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6940 and insert the version number definitions from .version
6942 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6944 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6945 added - genarate auto-host.h using auto-host_vc_in.h as template
6948 removed from CVS, generated automatically
6950 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6951 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6953 2002-08-11 Borut Razem <borut.razem AT siol.net>
6954 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6956 2002-08-10 Borut Razem <borut.razem AT siol.net>
6957 * src/SDCCmain.c (main):
6958 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6959 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6960 The consequence was that some temporary files were not removed.
6963 unification of code in functions tempfilename() and tempfile():
6964 function tempnam() is defined in Visual Studio 6.0 and .NET
6966 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6968 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6969 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6970 - removed compiler command line option /WX: Treats all warnings as errors
6971 - update a list of source files, included into the project
6973 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

6987 added newline in the def file to keep MSC compiler satisfied
6989 * sdcc/src/z80/gen.c:
6990 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6991 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC

7171 * sdcc/src/SDCCloop.c:
7172 Previous fix was not good. basic blocks that have "break" or "return" are
7173 not really partof a loop , but live ranges used in these blocks should
7174 be live thru the entire loop, so set partOfLoop but don't add them to
