63 Adding support for replacing ljmps with sjmps in jumptables
64 generated for switch statements. For now you need to set the
65 environment variable SDCC_SJMP_JUMPTABLE to enable this.
66 Now 4 algorithms for mcs51 jumptable generation are used:
67 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

98 * (malloc.h): added CVS Id tag,
99 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
101 * added libc directory. The current version of LibC contains string
102 functions, ctype functions and macros and some functions of the
103 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
104 be extensively tested in the future. Standard disclaimer here.
105 Library is not automatically build yet. But one can build it by
106 invoking 'make' inside the libc directory.

119 special compare&skip instructions. Initial tests fail some times
120 with variables grater than 1 byte in size, so new code is disabled,
121 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
123 * (genCast): began a fix to optimize the casting of a bit to another
124 bit, now assigning a bitfield to another bitfield will fail, sorry,

3150 loaded with the linker search paths (-L arguments) and the libraries
3151 to be linked with the current source (-l arguments). Changes
3152 currently will affect only the pic16 port.
3153 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3154 include path the port specific paths and port specific libraries,
3155 * gplink command now contains the $3 argument,

3160 * src/pic16/glue.c (pic16glue): corrected bug with code
3161 initialization which bypassed the variable initializations block.
3163 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3164 COMPILE_FLAGS and added the --nostdinc option
3166 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3168 * device/include/mc68hc908jb8.h: Register defs for another member

3171 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3173 Documenting changes from previous commits.
3174 * configure.in (version 1.56),
3175 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3176 when generating output files to configure the pic16 library,
3177 but now I've commented it out, since gputils aren't installed in the
3178 SF compile farm, so library won't compile
3180 * device/lib/Makefile.in (version 1.56): initially I've added in
3181 target 'all' the prerequestive 'model-pic16' so it compiled the
3182 pic16 library, but now I've commented it out for the same reasons
3184 * added targets 'model-pic16' and 'objects-pic16' to compile the
3186 * added target 'port-specific-objects-pic16' to handle the
3187 generated libraries and copy them into the build/ directory
3188 * added target 'clean-intermediate-pic16' to clean intermediate
3189 files into pic16 directory
3190 * in target 'installdirs' added line to create directory pic16 in
3191 the installation path
3193 * device/include/Makefile.in (version 1.11): in target 'install'
3194 added lines to copy all header files to installation path,
3195 * in target 'installdirs' added line create directory for pic16
3196 headers in the installation path
3198 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3211 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3212 option so that it actually works. Made it specific to the z80, since
3213 the gbz80 doesn't have these kinds of I/O ports.
3215 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3217 * device/include/z180.h,

3230 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3232 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3233 changed interrupt vector table generation to only emit declared vectors.
3234 * device/include/Makefile.in: added missing backslash
3235 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

3239 Mainly changes to support compilation of the device libraries
3240 * src/pic16/device.c: stack is allocated via symbol and not
3241 via literal number. The symbol is placed in the corresponding
3242 position of the data ram
3243 * (pic16_dump_section): relocatable and absolute uninitialized
3244 data are now emitted in sorted order to reduce section naming,
3245 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3246 weren't marked as being in the access bank,
3248 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3250 Added portion of GNU PIC Library under the directory
3251 device/include/pic16 and device/lib/pic16. These files
3252 contain the declarations of SFRs for the PIC18Fxx2 devices.
3253 The directory is initialized via configure from toplevel.
3255 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3257 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3258 the spilllocations to be compared correctly
3260 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3262 * src/SDCCast.c (decorateType): fixed bug introduced today
3264 2004-01-12 Borut Razem <borut.razem AT siol.net>

3280 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3282 * doc/sdccman.lyx: Moved and added some sections, small changes
3283 all over. Telling LaTeX to be less strict with word spacing
3284 to better keep the right margin. Changed some notes about
3285 maintainance of the ports in section 3.2.1 - is it OK like this?
3287 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3324 UPPER for immediate operands,
3325 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3327 * src/pic16/peeph.def: all peepholes with movff are commented out,
3328 because there is a problem in the pcode peep optimizer,
3329 * src/pic16/ralloc.c: the register allocator can now reuse local
3330 function symbols for another function. This saves register usage.
3331 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3333 Added file src/pic16/NOTES with information about program writing on
3334 the current port version.

3343 * src/SDCCmain.c : fixed #872250: -l command line defined library
3344 files are scanned before standard library files
3346 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3363 gen51Code): more efficient parameter receive for --model-large
3366 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3369 * src/z80/main.c: added missed needLinkerScript flags (more than
3370 one port structure defined in these file)
3371 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3387 needLinkerScript flag
3389 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3390 * src/pic/glue.c: added variable udata_section_name to
3391 override default uninitialized data segment definition for
3392 devices only with SHAREBANK memory (reported from Erik Epetrich)
3393 * (pic14emitOverlay): modified to emit a commented overlay segment
3394 directive when no overlay data exist
3395 * (picglue): modified to emit uninitialized data segment
3396 according to udata_section_name

3402 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3403 object file from '.rel' to '.o' in port->linker structure,
3404 changed size of fptr from 2 to 3 in port structure
3406 2004-01-07 Borut Razem <borut.razem AT siol.net>
3408 * support/scripts/sdcc.nsi: update PATH
3409 * support/scripts/sdcc.ico: craeted

3422 include information about variables allocated to the overlay
3425 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3427 * as/mcs51/lkmain.c: Help about -Y option

3439 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3441 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3442 (default behaviour).
3444 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3446 A python script to validate compiler diagnostic messages. It can be
3447 used to verify that sdcc complains about bad c source code and
3448 gives a good location of the error.
3449 * support/valdiag/Makefile,
3450 * support/valdiag/valdiag.py,
3451 * support/valdiag/tests/*
3453 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3466 * src/common.h: added ifndef/define/endif macros
3467 around the header file.
3468 Bug reported from Jesus Calvino-Fraga
3470 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3472 * sdcc.spec: updated
3473 * device/include/Makefile.in: don't install CVS directories
3474 * device/lib/Makefile.in: added removal of CVS directories after install
3475 * doc/Makefile: fixed install, added local_icons
3476 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3477 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3478 * src/ds390/gen.c (genRightShift): fixed bug #870788
3479 * src/SDCCast.c (decorateType): fixed bug #870781
3481 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3483 PIC16 port related changes:
3484 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3485 added variable stackPos,
3487 * gen.c: genCall, assignResultValue: added support for
3488 pushing/retrieving function parameters to/from stack,
3489 genFunction,genEndFunction: setup stack frame for the
3491 genAddrOf: will be changed according to bug 863624
3493 * added files genutils.c and genutils.h which contain gen*
3494 debugged and optimised functions extracted from gen.c
3496 * glue.c: added variable 'externs' which holds extern symbols,
3497 pic16emitRegularMap: is modified to properly handle relocatable
3498 symbols under the new scheme,
3499 pic16createInterruptVect: is modified
3500 pic16printPublics: is modified to emit 'global' assembler directives,
3501 added pic16_printExterns to print extern symbols,
3502 pic16glue: initializes stack/frame pointer in the beginning of
3503 the assembly output. Temporary hack, will be corrected later,
3504 because gplink yet does not support stack and SDCC does not
3505 yet support a type of crt0.o object to create the final binary.
3507 * Removed many lines that contain 8051 legacy code.
3508 * The code is finally placed under a 'code' directive.
3509 * Added port specific options.
3511 * _process_pragma: simplified since now we do not need *special*
3512 include file to define SFR registers. But a separate header
3513 will be needed. This will be developed later.
3514 * _pic16_parseOptions: added, parses port specific options:
3515 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3516 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3517 --preplace-udata-with=
3519 * _pic16_setDefaultOptions: modified to initialize section names,
3520 but hack is temporarly out of order since it needs improvement.
3521 * _pic16_genAssemblerPreamble: configuration words are emitted by
3522 their address instead of their name. This part is incomplete and
3523 supports only the 18Fxx2 devices. Other devices will emit an error
3524 during assembly since they do not contain the same set of config
3526 * _pic16_genIVT: is modified,
3528 * pcode.c: added definitions for some hardware registers that are needed
3530 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3531 All PCI entries are updated. Now LFSR is supported.
3532 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3533 * added pic16_newpCodeOpLit2 to support instructions with
3534 two literal arguments
3535 * pic16_pCode2str: corrected code that emits assembler instructions
3536 with two literal operands and those that have an access bit modifier
3537 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3538 this fixes a bug which caused some labels to be lost, when an
3539 assembler directive was added, i.e. banksel,
3540 * pic16_FixRegisterBanking: improved logic that causes the insertion
3542 * InlineFunction: functions that are called once, are not any more
3543 inlined. This can be a port option in the future,
3545 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3547 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3548 hold the corresponding uninitialized symbols,
3549 * pic16_allocProcessorRegister: registers have explicit marked the
3551 * pic16_allocInternalRegister: registers are explicit marked as
3553 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3554 processing list, so bit registers were lost,
3557 * ralloc.h: added field 'accessBank' and original symbol operand
3558 in register definition,
3559 * removed the field isMapped from register definition,
3561 ** Several functions have been removed from various sources:
3562 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3563 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3564 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3565 pic16_assignRelocatableRegisters
3567 ** others have been introduced:
3568 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3569 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3571 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3573 * support/scripts/inc2h.pl: changed definition of BIT_AT
3574 to emit 'sbit at' instead of 'bit at'. This was a request.
3576 PIC16 port related preliminary changes:
3577 * gen.c: prefixed function popRegFromString with
3578 pic16_ and all references to it corrected
3579 * pcode.c: all pic16_pc_* hardware registers prefixed
3580 with underscore (_),
3581 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3582 * ralloc.c: newReg(): when register is REG_SFR then
3583 set address to rIdx,
3584 pic16_allocProcessorRegister(): marks register wasUsed=0
3585 pic16_writeUsedRegs(): added a call to assign processor
3586 registers via pic16_assignFixedRegisters
3588 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3590 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3591 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3592 variables in unused register banks. Also the SSEG is placed
3593 wherever there is enough space for it, and IDATA can be anywhere
3594 in internal RAM. For now compile using -Wl-Y[stack_size].
3595 The mem file is different for this option as well, since it
3596 makes no sense of talking about DSEG lenght.
3598 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3600 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3601 in certain cases, e.g. when ROM assignment, patch provided
3602 from Albert den Haan.
3604 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4647 A few small changes that speed up the peephole optimizer.
4651 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4653 Try to make the peephole optimizer smarter by maintaining
4654 an association between the assembly source code and the
4655 iCodes that originated them. Put this information to use
4656 with a new peephole rule condition "notVolatile" so that
4657 the rules can be aggressive yet still safe.
4662 * src/mcs51/peeph.def
4664 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4668 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4669 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4670 if the left or right operand symbols have the accuse flag set.
4672 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4674 Changed the type of the result of the ! (NOT) operator to char;
4675 previously it returned the same type as the source. This allows
4676 us to eliminate all the genFloatNot functions (all of its target
4677 implementations were very buggy) since !float can use the same
4680 * src/SDCCicode.c (ast2iCode): ! returns char
4681 * src/mcs51/gen.c (genNot, genNotFloat),
4682 * src/ds390/gen.c (genNot, genNotFloat),
4683 * src/z80/gen.c (genNot, genNotFloat),
4684 * src/pic/gen.c (genNot, genNotFloat),
4685 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

4689 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4690 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4691 during interrupts. Ensure WSAVE is located at a shared bank address.
4692 2. Fixed page selection in some places
4693 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4694 the registers name strings.
4695 4. Fixed "signed / unsigned compare" compiler warnings.
4696 5. The PIC port manages its own allocation of the general purpose
4697 registers, but makes no attempt to reuse them. As a result when
4698 compiling it soon runs out of general purpose registers. Some
4699 additional code was added to the files pcode.c and device.c to walk
4700 through the function call tree and rename the registers so that they
4710 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4711 genPlus() & genMinus() when the result is the same as left or right

4717 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4719 Made bitfield a distinct type from bit so that bitfields
4720 convert as per ANSI C and bits retain their traditional
4721 boolean style behaviour. Implemented bitfield support in
4729 * src/ds390/gen.c: bit v bitfield split
4730 * src/z80/gen.c: New support for bitfields
4731 * support/regression/tests/bitfields.c: reenabled z80,
4734 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4736 Rules 246.x, 247.x relate to bitfields, the others speed up
4737 access to xdata mapped I/O devices.
4739 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4741 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4743 Cleaned up genPackBits and genUnpackBits and added two helper
4744 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4745 for literal assignments in genPackBits (thanks to Frieder for
4751 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4753 Fixed bug #748310 (pointer to function type mishandled when the
4754 function name is omitted). Also fixed a SIGSEGV when a function
4755 attribute (reentrant, etc) is used on a non-function or on a
4756 function but misplaced before the parameter list.
4758 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4760 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4783 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4785 Made the constant following the "interrupt" keyword optional. If
4786 omitted, the function will not automatically be given an entry
4787 in the interrupt vector table (similar to #pragma NOIV, but
4788 less syntacticly kludgy). The interrupt number is also now
4789 range checked. Also fixed a bug in the high order bit example

4805 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4807 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4808 be re-activated by defining REDUCE_LITERALS)

4810 unsigned, but are signed by default
4811 * src/SDCCval.c (constVal): rearranged
4812 * src/SDCCval.c (valMod): preliminary fix
4813 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5249 * device/lib/gbz80/mul.s
5250 * device/lib/gbz80/stubs.s
5251 * device/lib/z80/mul.s
5252 * device/lib/z80/stubs.s
5253 * src/SDCCsymt.c (initCSupport)
5255 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5257 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
5258 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5259 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5260 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5263 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5265 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5266 the regression tests I'm not brave enough to enable 245.b, 245.c
5267 * doc/sdccman.lyx: added latex preamble for hyperref package.
5268 Using pdflatex this will give you a hyperlinked pdf file with
5269 bookmarks. (prepend '%' before /usepackage if this breaks something)
5271 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5281 * src/SDCCglue.c (printIval): fixed bug #739934
5283 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
5285 Applied patch from bug 737905 (renamed yylineo to mylineno):
5292 * src/pic16/pcode.c: Cleaned warnings
5293 * src/pic16/pcodeflow.c: Cleaned warnings
5294 * src/pic16/pcoderegs.c: Cleaned warnings

5307 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5309 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5310 it can be defined with CFLAGS when running configure
5311 * src/SDCCmain.c: fixed compiling + linking with object files
5313 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5315 * configure.in: configure for pic16 port,
5316 added --disable-pic16-port
5317 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5318 * src/SDCCmain.c: linkOptions is changed to set *,
5319 added if/endif conditional macros to remove options help
5320 messages from optionsTable when a port is not configured, added
5321 support for the PIc16 port in the ports table, when executing
5322 the compiler with no port specified on command line, a default
5323 port is selected with the new macro DEFAULT_PORT which is
5324 defined in port.h, in setDefaultOptions() linkOptions is removed
5325 from initialization assignment, since now it is a set,
5326 parseCmdLine uses setParseWithComma for linkOptions, in
5327 linkEdit() linkOptions are accessed with new function indexSet()
5328 which returns the i'th item of a set variable. See SDCCset.c, in
5329 linkEdit() when calling buildCmdLine(), added linkOptions as
5330 last argument. Now users can pass arguments to gplink via the
5331 -Wl option, main() uses pic16glue() to glue up pic16 programs
5332 * src/SDCCpeeph.c: various changes to support pic16
5333 * src/SDCCset.c: added function void *indexSet(set *, int) to

5343 * src/pic16/glue.c: commented out some error producing lines
5344 * src/pic16/main.c: __config directives are commented out to stop
5345 gpasm complaining and test the linkage with gplink, _linkCmd and
5346 _asmCmd changed to be more gplink and gpasm friendly
5347 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5348 produced an error when parsed, peep rule 12 is added to utilize
5349 movff, but it is commented out since the pCode does not support
5350 yet a command with 2 address arguments
5352 2003-05-18 <johan AT balder>
5354 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5355 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5356 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

5379 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5381 2003-05-11 Borut Razem <borut.razem AT siol.net>
5383 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5384 the path of bin directory, so that PATH is the only env. variable, which has to be set
5385 in case of standard installation.
5386 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6389 * src/SDCCicode.c: fixed array add
6391 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6392 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6393 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6395 2003-01-04 <johan AT balder>
6397 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6399 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6400 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6402 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6403 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6412 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6413 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6415 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6417 * in \sdcc\as\mcs51\ changed these files in order to create an
6418 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6419 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6420 following files to include the previous two files: aslink.dsp,
6421 Makefile.aslink, Makefile.bcc, and Makefile.in.
6423 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6424 .adb instead of .cdb
6426 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6428 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6429 value from option --iram-size.
6431 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6433 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6436 2002-09-18 <wiml AT hhhh.org>
6438 * SDCClrange.h: exposed setFromRange() and setToRange()
6439 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6440 packRegsForAccUse() (bug 542397)
6441 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6442 multiple times and emitting the fetch operations more than once
6443 added aopGetUsesAcc() function to allow binary operators to
6444 fetch their operands in the correct order; made genMinus() emit
6445 compact code for X = LITERAL - Y
6447 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6448 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6449 sprintf() in line 1267.
6451 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6452 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6455 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6456 Changes to aslink (All the changes are marked with 'JCF'):
6458 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6461 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6462 area BSEG. Also moves, if possible, the DATA area down into the internal
6463 ram so more space is available.
6465 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6468 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6469 not bytes. Function summary() which creates a memory usage summary
6470 file with extension .mem. Reports of overlaping stack and small stack
6471 size. If the space for the stack is less than 16 bytes aslink trows a
6474 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6475 the 8051. Option 'y' for memory summary output file.
6477 Changes to sdcc (All the changes are marked with 'JCF'):
6479 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6481 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6482 overlaying area for it (uses RegBankUsed[4]).
6484 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6485 bank zero as used by default. By default aslink locates the stack
6486 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6487 the creation of the .mem file. Delegates the allocation of data area
6488 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6489 the begining of the stack area to aslink.
6491 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6492 glue() in SDCCglue.c creates an area for it.
6494 2002-09-03 Borut Razem <borut.razem AT siol.net>
6495 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6496 sdcc/src/pic/glue.c:
6497 introduced atexit() handler for teporay files removal in case of
6498 errors, assertions, ...
6500 2002-08-29 Borut Razem <borut.razem AT siol.net>
6501 * sdcc/support/cpp2/auto-host_vc_in.h:
6502 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6503 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6504 Maybe there is a similar problem with BORLANDC? It should be checked!
6506 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6507 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6508 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6509 was not executed, and the compiler (cl) launched a warning:
6510 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6512 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6513 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6515 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6516 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6518 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6519 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6520 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6521 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6522 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6523 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6524 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6525 - added Release configuration in VS projects
6526 - review of compiler an linker options
6527 - VC .exe files are generated in bin_vc directory, not to interfere
6528 with binaries generated from other projects (cygwin, mingw, bcc ...)
6530 * sdcc/src/yacc.dsp: added
6532 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6533 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6534 and insert the version number definitions from .version
6536 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6538 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6539 added - genarate auto-host.h using auto-host_vc_in.h as template
6542 removed from CVS, generated automatically
6544 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6545 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6547 2002-08-11 Borut Razem <borut.razem AT siol.net>
6548 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6550 2002-08-10 Borut Razem <borut.razem AT siol.net>
6551 * src/SDCCmain.c (main):
6552 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6553 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6554 The consequence was that some temporary files were not removed.
6557 unification of code in functions tempfilename() and tempfile():
6558 function tempnam() is defined in Visual Studio 6.0 and .NET
6560 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6562 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6563 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6564 - removed compiler command line option /WX: Treats all warnings as errors
6565 - update a list of source files, included into the project
6567 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

6580 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6581 added newline in the def file to keep MSC compiler satisfied
6583 * sdcc/src/z80/gen.c:
6584 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6585 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6586 - solved MSC error in function aopDump()
6588 * sdcc_vc.h: define PREFIX as "\\sdcc"

6766 Previous fix was not good. basic blocks that have "break" or "return" are
6767 not really partof a loop , but live ranges used in these blocks should
6768 be live thru the entire loop, so set partOfLoop but don't add them to
