102 to call when a stack overflow occurs,
103 * (malloc.h): added CVS Id tag,
104 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
106 * added libc directory. The current version of LibC contains string
107 functions, ctype functions and macros and some functions of the
108 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
109 be extensively tested in the future. Standard disclaimer here.
110 Library is not automatically build yet. But one can build it by
111 invoking 'make' inside the libc directory.
112 * added ADC library under libio. Preliminary version yet.

124 special compare&skip instructions. Initial tests fail some times
125 with variables grater than 1 byte in size, so new code is disabled,
126 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
128 * (genCast): began a fix to optimize the casting of a bit to another
129 bit, now assigning a bitfield to another bitfield will fail, sorry,
130 * src/pic16/main.c: disabled the use of lr-support feature,
131 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

137 * (isBankInstruction): modified to return 0 for no banking instruction,
138 and 1 for banking instruction,
139 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
140 caused stop processing pCodes after a inline assembly block,
141 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3156 to be linked with the current source (-l arguments). Changes
3157 currently will affect only the pic16 port.
3158 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3159 include path the port specific paths and port specific libraries,
3160 * gplink command now contains the $3 argument,
3161 * src/pic16/device.h,
3162 * src/pic16/device.c,: structure PIC_device is made public and
3163 renamed to PIC16_device, the same for variable Pics which is renamed
3164 to Pics16. Updated all references to them.
3165 * src/pic16/glue.c (pic16glue): corrected bug with code
3166 initialization which bypassed the variable initializations block.
3168 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3169 COMPILE_FLAGS and added the --nostdinc option
3171 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3173 * device/include/mc68hc908jb8.h: Register defs for another member

3176 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3178 Documenting changes from previous commits.
3179 * configure.in (version 1.56),
3180 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3181 when generating output files to configure the pic16 library,
3182 but now I've commented it out, since gputils aren't installed in the
3183 SF compile farm, so library won't compile
3185 * device/lib/Makefile.in (version 1.56): initially I've added in
3186 target 'all' the prerequestive 'model-pic16' so it compiled the
3187 pic16 library, but now I've commented it out for the same reasons
3189 * added targets 'model-pic16' and 'objects-pic16' to compile the
3191 * added target 'port-specific-objects-pic16' to handle the
3192 generated libraries and copy them into the build/ directory
3193 * added target 'clean-intermediate-pic16' to clean intermediate
3194 files into pic16 directory
3195 * in target 'installdirs' added line to create directory pic16 in
3196 the installation path
3198 * device/include/Makefile.in (version 1.11): in target 'install'
3199 added lines to copy all header files to installation path,
3200 * in target 'installdirs' added line create directory for pic16
3201 headers in the installation path

3216 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3217 option so that it actually works. Made it specific to the z80, since
3218 the gbz80 doesn't have these kinds of I/O ports.
3220 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3222 * device/include/z180.h,

3235 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3237 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3238 changed interrupt vector table generation to only emit declared vectors.

3244 Mainly changes to support compilation of the device libraries
3245 * src/pic16/device.c: stack is allocated via symbol and not
3246 via literal number. The symbol is placed in the corresponding
3247 position of the data ram
3248 * (pic16_dump_section): relocatable and absolute uninitialized
3249 data are now emitted in sorted order to reduce section naming,
3250 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3251 weren't marked as being in the access bank,
3253 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3255 Added portion of GNU PIC Library under the directory
3256 device/include/pic16 and device/lib/pic16. These files
3257 contain the declarations of SFRs for the PIC18Fxx2 devices.
3258 The directory is initialized via configure from toplevel.
3260 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3262 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3263 the spilllocations to be compared correctly
3265 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3267 * src/SDCCast.c (decorateType): fixed bug introduced today
3269 2004-01-12 Borut Razem <borut.razem AT siol.net>

3287 * doc/sdccman.lyx: Moved and added some sections, small changes
3288 all over. Telling LaTeX to be less strict with word spacing
3289 to better keep the right margin. Changed some notes about
3290 maintainance of the ports in section 3.2.1 - is it OK like this?
3292 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3329 UPPER for immediate operands,
3330 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3332 * src/pic16/peeph.def: all peepholes with movff are commented out,
3333 because there is a problem in the pcode peep optimizer,
3334 * src/pic16/ralloc.c: the register allocator can now reuse local
3335 function symbols for another function. This saves register usage.
3336 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3338 Added file src/pic16/NOTES with information about program writing on
3339 the current port version.

3371 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3374 * src/z80/main.c: added missed needLinkerScript flags (more than
3375 one port structure defined in these file)
3376 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3392 needLinkerScript flag
3394 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3395 * src/pic/glue.c: added variable udata_section_name to
3396 override default uninitialized data segment definition for
3397 devices only with SHAREBANK memory (reported from Erik Epetrich)
3398 * (pic14emitOverlay): modified to emit a commented overlay segment
3399 directive when no overlay data exist
3400 * (picglue): modified to emit uninitialized data segment
3401 according to udata_section_name

3411 2004-01-07 Borut Razem <borut.razem AT siol.net>
3413 * support/scripts/sdcc.nsi: update PATH
3414 * support/scripts/sdcc.ico: craeted
3416 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3427 include information about variables allocated to the overlay
3430 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3432 * as/mcs51/lkmain.c: Help about -Y option

3444 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3446 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3447 (default behaviour).
3449 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3451 A python script to validate compiler diagnostic messages. It can be
3452 used to verify that sdcc complains about bad c source code and
3453 gives a good location of the error.
3454 * support/valdiag/Makefile,
3455 * support/valdiag/valdiag.py,
3456 * support/valdiag/tests/*
3458 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3471 * src/common.h: added ifndef/define/endif macros
3472 around the header file.
3473 Bug reported from Jesus Calvino-Fraga
3475 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3477 * sdcc.spec: updated
3478 * device/include/Makefile.in: don't install CVS directories
3479 * device/lib/Makefile.in: added removal of CVS directories after install
3480 * doc/Makefile: fixed install, added local_icons
3481 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3482 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3483 * src/ds390/gen.c (genRightShift): fixed bug #870788
3484 * src/SDCCast.c (decorateType): fixed bug #870781
3486 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3488 PIC16 port related changes:
3489 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3490 added variable stackPos,
3492 * gen.c: genCall, assignResultValue: added support for
3493 pushing/retrieving function parameters to/from stack,
3494 genFunction,genEndFunction: setup stack frame for the
3496 genAddrOf: will be changed according to bug 863624
3498 * added files genutils.c and genutils.h which contain gen*
3499 debugged and optimised functions extracted from gen.c
3501 * glue.c: added variable 'externs' which holds extern symbols,
3502 pic16emitRegularMap: is modified to properly handle relocatable
3503 symbols under the new scheme,
3504 pic16createInterruptVect: is modified
3505 pic16printPublics: is modified to emit 'global' assembler directives,
3506 added pic16_printExterns to print extern symbols,
3507 pic16glue: initializes stack/frame pointer in the beginning of
3508 the assembly output. Temporary hack, will be corrected later,
3509 because gplink yet does not support stack and SDCC does not
3510 yet support a type of crt0.o object to create the final binary.
3512 * Removed many lines that contain 8051 legacy code.
3513 * The code is finally placed under a 'code' directive.
3514 * Added port specific options.
3516 * _process_pragma: simplified since now we do not need *special*
3517 include file to define SFR registers. But a separate header
3518 will be needed. This will be developed later.
3519 * _pic16_parseOptions: added, parses port specific options:
3520 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3521 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3522 --preplace-udata-with=
3524 * _pic16_setDefaultOptions: modified to initialize section names,
3525 but hack is temporarly out of order since it needs improvement.
3526 * _pic16_genAssemblerPreamble: configuration words are emitted by
3527 their address instead of their name. This part is incomplete and
3528 supports only the 18Fxx2 devices. Other devices will emit an error
3529 during assembly since they do not contain the same set of config
3531 * _pic16_genIVT: is modified,
3533 * pcode.c: added definitions for some hardware registers that are needed
3535 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3536 All PCI entries are updated. Now LFSR is supported.
3537 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3538 * added pic16_newpCodeOpLit2 to support instructions with
3539 two literal arguments
3540 * pic16_pCode2str: corrected code that emits assembler instructions
3541 with two literal operands and those that have an access bit modifier
3542 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3543 this fixes a bug which caused some labels to be lost, when an
3544 assembler directive was added, i.e. banksel,
3545 * pic16_FixRegisterBanking: improved logic that causes the insertion
3547 * InlineFunction: functions that are called once, are not any more
3548 inlined. This can be a port option in the future,
3550 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3552 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3553 hold the corresponding uninitialized symbols,
3554 * pic16_allocProcessorRegister: registers have explicit marked the
3556 * pic16_allocInternalRegister: registers are explicit marked as
3558 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3559 processing list, so bit registers were lost,
3562 * ralloc.h: added field 'accessBank' and original symbol operand
3563 in register definition,
3564 * removed the field isMapped from register definition,
3566 ** Several functions have been removed from various sources:
3567 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3568 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3569 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3570 pic16_assignRelocatableRegisters
3572 ** others have been introduced:
3573 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3574 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3576 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3578 * support/scripts/inc2h.pl: changed definition of BIT_AT
3579 to emit 'sbit at' instead of 'bit at'. This was a request.
3581 PIC16 port related preliminary changes:
3582 * gen.c: prefixed function popRegFromString with
3583 pic16_ and all references to it corrected
3584 * pcode.c: all pic16_pc_* hardware registers prefixed
3585 with underscore (_),
3586 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3587 * ralloc.c: newReg(): when register is REG_SFR then
3588 set address to rIdx,
3589 pic16_allocProcessorRegister(): marks register wasUsed=0
3590 pic16_writeUsedRegs(): added a call to assign processor
3591 registers via pic16_assignFixedRegisters
3593 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3595 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3596 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3597 variables in unused register banks. Also the SSEG is placed
3598 wherever there is enough space for it, and IDATA can be anywhere
3599 in internal RAM. For now compile using -Wl-Y[stack_size].
3600 The mem file is different for this option as well, since it
3601 makes no sense of talking about DSEG lenght.
3603 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3605 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3606 in certain cases, e.g. when ROM assignment, patch provided
3607 from Albert den Haan.
3609 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4652 A few small changes that speed up the peephole optimizer.
4656 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4658 Try to make the peephole optimizer smarter by maintaining
4659 an association between the assembly source code and the
4660 iCodes that originated them. Put this information to use
4661 with a new peephole rule condition "notVolatile" so that
4662 the rules can be aggressive yet still safe.
4667 * src/mcs51/peeph.def
4669 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4673 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4674 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4675 if the left or right operand symbols have the accuse flag set.
4677 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4679 Changed the type of the result of the ! (NOT) operator to char;
4680 previously it returned the same type as the source. This allows
4681 us to eliminate all the genFloatNot functions (all of its target
4682 implementations were very buggy) since !float can use the same
4685 * src/SDCCicode.c (ast2iCode): ! returns char

4694 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4695 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4696 during interrupts. Ensure WSAVE is located at a shared bank address.
4697 2. Fixed page selection in some places
4698 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4699 the registers name strings.
4700 4. Fixed "signed / unsigned compare" compiler warnings.
4701 5. The PIC port manages its own allocation of the general purpose
4702 registers, but makes no attempt to reuse them. As a result when
4703 compiling it soon runs out of general purpose registers. Some
4704 additional code was added to the files pcode.c and device.c to walk
4705 through the function call tree and rename the registers so that they
4715 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4716 genPlus() & genMinus() when the result is the same as left or right

4722 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4724 Made bitfield a distinct type from bit so that bitfields
4725 convert as per ANSI C and bits retain their traditional
4726 boolean style behaviour. Implemented bitfield support in
4734 * src/ds390/gen.c: bit v bitfield split
4735 * src/z80/gen.c: New support for bitfields
4736 * support/regression/tests/bitfields.c: reenabled z80,
4739 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4741 Rules 246.x, 247.x relate to bitfields, the others speed up
4742 access to xdata mapped I/O devices.
4744 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4746 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4748 Cleaned up genPackBits and genUnpackBits and added two helper
4749 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4750 for literal assignments in genPackBits (thanks to Frieder for
4756 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4758 Fixed bug #748310 (pointer to function type mishandled when the
4759 function name is omitted). Also fixed a SIGSEGV when a function
4760 attribute (reentrant, etc) is used on a non-function or on a
4761 function but misplaced before the parameter list.
4763 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4765 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4788 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4790 Made the constant following the "interrupt" keyword optional. If
4791 omitted, the function will not automatically be given an entry
4792 in the interrupt vector table (similar to #pragma NOIV, but
4793 less syntacticly kludgy). The interrupt number is also now
4794 range checked. Also fixed a bug in the high order bit example

5235 condition and ignore commands.
5237 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5239 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
5240 is in parts still quite out of date, I did changes as far as I felt makes sense
5241 for a non-native english speaker.
5242 Please feel free to add to the manual or to correct my changes.
5243 * doc/Makefile: undid touching the date of intermediate tex files.
5245 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5260 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5262 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
5263 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
5264 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
5265 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
5268 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5270 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5271 the regression tests I'm not brave enough to enable 245.b, 245.c
5272 * doc/sdccman.lyx: added latex preamble for hyperref package.
5273 Using pdflatex this will give you a hyperlinked pdf file with
5274 bookmarks. (prepend '%' before /usepackage if this breaks something)
5276 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5286 * src/SDCCglue.c (printIval): fixed bug #739934
5288 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
5290 Applied patch from bug 737905 (renamed yylineo to mylineno):
5297 * src/pic16/pcode.c: Cleaned warnings
5298 * src/pic16/pcodeflow.c: Cleaned warnings
5299 * src/pic16/pcoderegs.c: Cleaned warnings

5310 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
5312 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5314 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5315 it can be defined with CFLAGS when running configure
5316 * src/SDCCmain.c: fixed compiling + linking with object files
5318 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5320 * configure.in: configure for pic16 port,
5321 added --disable-pic16-port
5322 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5323 * src/SDCCmain.c: linkOptions is changed to set *,
5324 added if/endif conditional macros to remove options help
5325 messages from optionsTable when a port is not configured, added
5326 support for the PIc16 port in the ports table, when executing
5327 the compiler with no port specified on command line, a default
5328 port is selected with the new macro DEFAULT_PORT which is
5329 defined in port.h, in setDefaultOptions() linkOptions is removed
5330 from initialization assignment, since now it is a set,
5331 parseCmdLine uses setParseWithComma for linkOptions, in
5332 linkEdit() linkOptions are accessed with new function indexSet()
5333 which returns the i'th item of a set variable. See SDCCset.c, in
5334 linkEdit() when calling buildCmdLine(), added linkOptions as
5335 last argument. Now users can pass arguments to gplink via the
5336 -Wl option, main() uses pic16glue() to glue up pic16 programs
5337 * src/SDCCpeeph.c: various changes to support pic16
5338 * src/SDCCset.c: added function void *indexSet(set *, int) to
5339 return the i'th item of the set

5342 * src/clean.mk: added pic16 in CLEANALLPORTS variable
5343 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
5344 added macro DEFAULT_PORT
5345 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
5346 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5348 * src/pic16/glue.c: commented out some error producing lines
5349 * src/pic16/main.c: __config directives are commented out to stop
5350 gpasm complaining and test the linkage with gplink, _linkCmd and
5351 _asmCmd changed to be more gplink and gpasm friendly
5352 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5353 produced an error when parsed, peep rule 12 is added to utilize
5354 movff, but it is commented out since the pCode does not support
5355 yet a command with 2 address arguments
5357 2003-05-18 <johan AT balder>
5359 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5360 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5379 on entry now. Add tbreak. Other enhancements and fixes for use
5382 2003-05-12 Borut Razem <borut.razem AT siol.net>
5384 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5386 2003-05-11 Borut Razem <borut.razem AT siol.net>
5388 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5389 the path of bin directory, so that PATH is the only env. variable, which has to be set
5390 in case of standard installation.
5391 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6420 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6422 * in \sdcc\as\mcs51\ changed these files in order to create an
6423 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6424 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6425 following files to include the previous two files: aslink.dsp,
6426 Makefile.aslink, Makefile.bcc, and Makefile.in.
6428 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6429 .adb instead of .cdb
6431 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6433 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6434 value from option --iram-size.
6436 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6438 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6441 2002-09-18 <wiml AT hhhh.org>
6443 * SDCClrange.h: exposed setFromRange() and setToRange()
6444 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6445 packRegsForAccUse() (bug 542397)
6446 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6447 multiple times and emitting the fetch operations more than once
6448 added aopGetUsesAcc() function to allow binary operators to
6449 fetch their operands in the correct order; made genMinus() emit
6450 compact code for X = LITERAL - Y
6452 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6453 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6454 sprintf() in line 1267.
6456 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6457 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6460 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6461 Changes to aslink (All the changes are marked with 'JCF'):
6463 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6466 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6467 area BSEG. Also moves, if possible, the DATA area down into the internal
6468 ram so more space is available.
6470 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6473 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6474 not bytes. Function summary() which creates a memory usage summary
6475 file with extension .mem. Reports of overlaping stack and small stack
6476 size. If the space for the stack is less than 16 bytes aslink trows a
6479 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6480 the 8051. Option 'y' for memory summary output file.
6482 Changes to sdcc (All the changes are marked with 'JCF'):
6484 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6486 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6487 overlaying area for it (uses RegBankUsed[4]).
6489 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6490 bank zero as used by default. By default aslink locates the stack
6491 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6492 the creation of the .mem file. Delegates the allocation of data area
6493 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6494 the begining of the stack area to aslink.
6496 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6497 glue() in SDCCglue.c creates an area for it.
6499 2002-09-03 Borut Razem <borut.razem AT siol.net>
6500 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6501 sdcc/src/pic/glue.c:
6502 introduced atexit() handler for teporay files removal in case of
6503 errors, assertions, ...
6505 2002-08-29 Borut Razem <borut.razem AT siol.net>
6506 * sdcc/support/cpp2/auto-host_vc_in.h:
6507 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6508 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6509 Maybe there is a similar problem with BORLANDC? It should be checked!
6511 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6512 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6513 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6514 was not executed, and the compiler (cl) launched a warning:
6515 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6517 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6530 - added Release configuration in VS projects
6531 - review of compiler an linker options
6532 - VC .exe files are generated in bin_vc directory, not to interfere

6535 * sdcc/src/yacc.dsp: added
6537 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6538 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6539 and insert the version number definitions from .version
6541 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6543 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6547 removed from CVS, generated automatically
6549 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6550 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6552 2002-08-11 Borut Razem <borut.razem AT siol.net>
6553 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6555 2002-08-10 Borut Razem <borut.razem AT siol.net>
6556 * src/SDCCmain.c (main):
6557 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6558 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6559 The consequence was that some temporary files were not removed.
6562 unification of code in functions tempfilename() and tempfile():
6563 function tempnam() is defined in Visual Studio 6.0 and .NET
6565 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6567 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6568 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6569 - removed compiler command line option /WX: Treats all warnings as errors
6570 - update a list of source files, included into the project
6572 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6573 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6574 changed project type to Generic Project so that can be correcly converted to VS.NET project
6576 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6578 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

6582 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6583 added return 0 statements after assert() to make compiler happy
6585 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6586 added newline in the def file to keep MSC compiler satisfied
6588 * sdcc/src/z80/gen.c:
6589 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6590 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6591 - solved MSC error in function aopDump()
6593 * sdcc_vc.h: define PREFIX as "\\sdcc"
6595 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

6651 were not getting allocated.
6653 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6656 Fixed left shift. Will promote the left side of a left shift
6657 if a) left shifting more than size of operand or b) when assigned
6658 to something size > size of left side
6660 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6770 * sdcc/src/SDCCloop.c:
6771 Previous fix was not good. basic blocks that have "break" or "return" are
6772 not really partof a loop , but live ranges used in these blocks should
6773 be live thru the entire loop, so set partOfLoop but don't add them to
6776 2002-02-21 <johan AT FRIJA>
