829 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
831 Enabled VPATH feature: changed nearly all Makefiles (149 files).
832 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
834 One basic decision: e.g. src/clean.mk includes further files. In order
835 to make this work there are two solutions:
836 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
837 run configure on them. This way they can use
838 'include $(srcdir)/port-clean.mk'
839 - always include clean.mk by the Makefile at the same level. To avoid
840 that `make clean` tries to include and build Makefile.dep the
841 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
842 implemented, because now even `make uninstall` doesn't create
843 Makefile.in. clean.mk could be eliminated by pasting it in
846 * debugger/mcs51/Makefile.in: build own objects from library sources
847 (SLIB, SDCC) in current directory
849 * configure, configure.in: renamed --disable-device-lib-build in
850 --disable-device-lib; added --enable-doc, the required tools are
851 searched by configure; added result message; the toolchain for the
852 belonging ports are now only built, if the port is enabled.
854 * support/regression/*: all output is written in directory gen, because
855 the fwk and ports directories don't livet in the build tree using vpath
857 * doc/sdccman.lyx: renamed --disable-device-lib-build to
858 --disable-device-lib, added --enable-doc, added section VPATH
860 * sim/ucsim/configure.in,
861 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
862 z80 are enabled by default
864 2006-04-24 Raphael Neider <rneider AT web.de>
866 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
867 to config word, "pic14_"-prefixed some extern functions
868 (pic14_emitConfigWord): emit __config directive(s) if assignment to
869 config word has been found
870 * src/pic/device.h: added prototypes
871 * src/pic/pcode.c: added "pic14_"-prefix where needed

877 (pic14createInterruptVect): moved generating __config directives away

893 * device/examples/main8051.c: deleted - it was removed from CVS

896 * src/SDCCalloc.h: deleted - it was removed from CVS

1135 implemented patch 1120823 Thanks to Willy De la Court (normal
1136 interrupts need an interrupt number now if they are made critical),
1137 and enabled nesting of critical functions though not for gbz80
1138 (genCritical, genEndCritical): added functions
1139 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1140 * src/z80/mappings.i: added "ei" to all mappings

1152 the left operand is shorter than the result (c* = lit-c* + int),
1154 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1157 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1159 * src/.version: increased version number to 2.5.5
1160 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1161 linking is done manually in pic16 port's _linkEdit,
1162 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1163 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1164 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1165 allocate asmop as AOP_ACC,
1166 (aopForRemat): added parameter 'bool result' in function declaration,
1167 (pic16_aopGet): return AOP_ACC when accessing WREG,
1168 (pic16_popGetTempReg): minor modification,

1179 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1180 call to allocReg, not by manually allocating a new one,
1181 (pic16_assignRegisters): now before going through the register
1182 allocating functions mark all registers as free. This eliminates some
1183 side effects resulting from peephole parser done earlier in the backbone
1185 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1243 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1244 which dumps before the function entry point a data byte which represents
1245 the number of the local variables used by the specified function, added
1246 'xinst' for initial support for Extended Instruction Support,
1247 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1248 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1249 port->fun_prefix anymore (may change later),
1250 (genFunction, genEndFunction): do not store/restore local registers for
1251 _main (this should take care the --main-return command line option in
1253 (genOr): removed some legacy pic-port instructions,
1254 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1255 performing operations with SFR's causes data to be written more than
1256 once to each SFR. Perhaps SFRs should be handled in special cases...
1257 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1259 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1260 into account for stack starting position,

1262 --extended or -y for Extended Instruction Support,
1263 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1264 (deassignLRs): *** perhaps the most important change, old 'for' code
1265 (commented out for reference), didn't account for some registers which
1266 were left marked 'not free' after a pointer operation. The change
1267 reduces register usage a lot in some cases
1269 2006-03-04 Borut Razem <borut.razem AT siol.net>
1271 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3536 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3538 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3542 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3543 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3544 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3545 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3546 always available in leading double underscore form. The C99 support is
3547 mostly missing, but it's a start.
3548 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3549 reserved identifier "__data".
3551 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3564 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3566 * src/port.h (struct PORT),

3597 2005-03-20 Borut Razem <borut.razem AT siol.net>
3599 * support/scripts/inc2h.pl: WIN32 port

3627 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3629 * device/lib/printf_large.c: removed inline assembly for portability and
3630 readability. Use printf_fast if speed or size are more important.
3631 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3632 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3634 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3636 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3637 prevent compiler warning
3639 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3641 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3642 moved to level 0 and declared as static. Also they are explicit
3643 placed in access bank. This was necessery because some times they
3644 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3645 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3646 optimizations. Currently only compare to unsigned char is implemented,
3647 * src/pic16/gen.c: added fReturnIdx array,
3648 * (struct resolvedIfx) is moved to gen.h and made public,
3649 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3650 * (aopForSym): added an optimization to directly store in stack of
3651 the operand of a SEND iCode,
3652 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3653 but as registers instead (AOP_REG) using the fReturnIdx array,
3654 * (pic16_freeAsmop): remove the freed register from the
3655 _G.sregsAlloc field,
3656 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3657 a compare of 'WREG',
3658 * (pic16_popGetTempRegCond): changed function prototype, now
3659 function takes also a bitVector argument v which holds the current
3660 set of registers that are allocated for stack access by aopForSym,
3661 registers allocated in aopForSym for accessing stack symbols are not
3662 any more part of the functions usedRegs field,
3663 * (genCall): some times aopOp is called for a stack variable to be
3664 send, aopForSym might perform the push, if this is true make sure
3665 that genCall doesn't push the variable twice by testing _G.resDirect,
3666 * (genFunction): changed testing for unspecified interrupt number
3667 from 256 to INTNO_UNSPEC,
3668 * modified selection scheme of frame pointer generation. Previously
3669 if function did use local registers a frame pointer was generated,
3670 now a frame pointer is generated only if function has arguments
3671 (that need PLUSW2 register access), or has stack arguments, or the
3672 compiler is not instructed to omit the frame pointer,
3673 * (genEndFunction): before restoring local registers that were saved
3674 in the function preamble, also restore the registers that *might*
3675 have been allocated for stack access,
3676 * (genRet): removed some old comments,
3677 * (genCmp, the active (RN's) version): added a call to the
3678 pic16_genCmp_special function to perform the compare with a more
3679 robust and optimized way,
3680 * (genInline): a feature has been added in inline code generation,
3681 which allows a wildcard variable substitution when writing inline
3682 assembly. Code is incomplete and experimental therefore undocumented,
3683 * (genCast): changed order of aopOp for result and right to allow
3684 aopForSym to directly load the result if possible,
3685 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3686 perform an optimized compare on some selected special occasions,
3687 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3688 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3689 generate an IVT any more,
3690 * src/pic16/main.c (pic16_optionsTable): added command line option
3692 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3693 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3695 * src/pic16/NOTES: Raphael Neider added in list of active developers
3696 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3697 jumptable_end to prevent bug #,
3698 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3699 inCond and outCond fields,
3700 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3701 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3702 turn off register spilling,
3703 * (packRegsForOneUse): synced with other ports' versions although it
3704 is not used currently,
3705 * (pic16_packRegisters): added an optimization while reading
3706 structure bitfields, some registers may be saved (malloc code is
3707 decreased by 80 bytes)
3709 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3711 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3712 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3713 this can be optimized more?
3715 2005-03-10 Raphael Neider <rneider AT web.de>
3717 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3718 genNearPointerGet): (hopefully) fixed access to bitfields via
3719 pointers (p->bitN = x; and x = p->bitN; failed)
3721 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3764 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3765 to keep the correct label reference count when adding/removing references
3766 to labels. A peephole file using this is appended to patch #1144962.

3898 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3899 (sizeof(sectNames) changed to sizeof(sectName))
3900 Both patches fix segfaults under MinGW.
3902 2005-01-23 Raphael Neider <rneider AT web.de>
3904 * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
3905 Safe_[mc]?alloc()'ed variables
3906 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3907 of (byte sized) temporaries (assign them to WREG for now)
3908 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3909 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3910 this might fix SIGSEGVs on MinGW...

4338 "operandsNotRelated" -- similar to "operandsNotSame", but takes
4339 architecture specific register naming into account, handles n-way
4340 comparisons, and supports quoted literals
4341 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
4343 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4351 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4353 Adding support for replacing ljmps with sjmps in jumptables
4354 generated for switch statements. For now you need to set the
4355 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4356 Now 4 algorithms for mcs51 jumptable generation are used:
4357 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4358 addresses loaded pc-relative for up to 112 cases and stack-pushing
4359 target addresses loaded with offset from dptr for up to 256 cases.
4361 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4362 * src/mcs51/main.c: adapted constants for switch table generation
4363 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

4385 Large cummulative patch for pic16 port.
4386 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4387 to call when a stack overflow occurs,
4388 * (malloc.h): added CVS Id tag,
4389 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4391 * added libc directory. The current version of LibC contains string
4392 functions, ctype functions and macros and some functions of the
4393 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4394 be extensively tested in the future. Standard disclaimer here.
4395 Library is not automatically build yet. But one can build it by
4396 invoking 'make' inside the libc directory.
4397 * added ADC library under libio. Preliminary version yet.
4399 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4400 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4401 aopForRemat() now and not by pic16_aopOp(),

4403 temporary registers, its a buggy feature and will be removed,
4404 * (pic16_popGet): set register instance field in AOP_CRY,
4405 * (pic16_outBitC): fixed for results in size greater than 1,
4406 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4407 * (pic16_storeForReturn): optimized return of 0,
4408 * (genCmp): experimental code for new genCmp which uses PIC18's
4409 special compare&skip instructions. Initial tests fail some times
4410 with variables grater than 1 byte in size, so new code is disabled,
4411 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4413 * (genCast): began a fix to optimize the casting of a bit to another
4414 bit, now assigning a bitfield to another bitfield will fail, sorry,
4415 * src/pic16/main.c: disabled the use of lr-support feature,
4416 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4417 * added some function prototypes, added function _debugf prototype,
4418 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4419 bits with offset (case PO_GPR_BIT),
4420 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4422 * (isBankInstruction): modified to return 0 for no banking instruction,
4423 and 1 for banking instruction,
4424 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4425 caused stop processing pCodes after a inline assembly block,
4426 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4427 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4428 registers when it shouldn't,
4429 * src/pic16/ralloc.c (allocReg): add preliminary support for
4430 supporting a limited set of temporary registers,
4432 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4434 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4435 genDataPointerSet): ensure assignments always copy in MSB to LSB
4437 (loadRegFromAop): recognize CLRH optimization,
4438 (genFunction): optimize RECEIVE iCodes in reentrant functions
4440 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4442 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4443 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4445 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4451 * device/lib/_gptrget.c (_gptrget),
4452 * device/lib/_gptrgetc.c (_gptrgetc),
4453 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4454 instead of sjmp to ret
4455 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4456 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4458 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7441 to be linked with the current source (-l arguments). Changes
7442 currently will affect only the pic16 port.
7443 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7444 include path the port specific paths and port specific libraries,
7445 * gplink command now contains the $3 argument,
7446 * src/pic16/device.h,
7447 * src/pic16/device.c,: structure PIC_device is made public and
7448 renamed to PIC16_device, the same for variable Pics which is renamed
7449 to Pics16. Updated all references to them.
7450 * src/pic16/glue.c (pic16glue): corrected bug with code
7451 initialization which bypassed the variable initializations block.
7453 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7454 COMPILE_FLAGS and added the --nostdinc option
7456 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7458 * device/include/mc68hc908jb8.h: Register defs for another member
7459 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7461 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7463 Documenting changes from previous commits.
7464 * configure.in (version 1.56),
7465 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7466 when generating output files to configure the pic16 library,
7467 but now I've commented it out, since gputils aren't installed in the
7468 SF compile farm, so library won't compile
7470 * device/lib/Makefile.in (version 1.56): initially I've added in
7471 target 'all' the prerequestive 'model-pic16' so it compiled the
7472 pic16 library, but now I've commented it out for the same reasons
7474 * added targets 'model-pic16' and 'objects-pic16' to compile the
7476 * added target 'port-specific-objects-pic16' to handle the
7477 generated libraries and copy them into the build/ directory
7478 * added target 'clean-intermediate-pic16' to clean intermediate
7479 files into pic16 directory
7480 * in target 'installdirs' added line to create directory pic16 in
7481 the installation path
7483 * device/include/Makefile.in (version 1.11): in target 'install'
7484 added lines to copy all header files to installation path,
7485 * in target 'installdirs' added line create directory for pic16
7486 headers in the installation path

7501 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7502 option so that it actually works. Made it specific to the z80, since
7503 the gbz80 doesn't have these kinds of I/O ports.
7505 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7507 * device/include/z180.h,

7520 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7522 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7523 changed interrupt vector table generation to only emit declared vectors.

7525 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7527 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7529 Mainly changes to support compilation of the device libraries
7530 * src/pic16/device.c: stack is allocated via symbol and not
7531 via literal number. The symbol is placed in the corresponding
7532 position of the data ram
7533 * (pic16_dump_section): relocatable and absolute uninitialized
7534 data are now emitted in sorted order to reduce section naming,
7535 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7536 weren't marked as being in the access bank,
7538 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7540 Added portion of GNU PIC Library under the directory
7541 device/include/pic16 and device/lib/pic16. These files
7542 contain the declarations of SFRs for the PIC18Fxx2 devices.
7543 The directory is initialized via configure from toplevel.
7545 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7547 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7548 the spilllocations to be compared correctly
7550 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7552 * src/SDCCast.c (decorateType): fixed bug introduced today
7554 2004-01-12 Borut Razem <borut.razem AT siol.net>

7572 * doc/sdccman.lyx: Moved and added some sections, small changes
7573 all over. Telling LaTeX to be less strict with word spacing
7574 to better keep the right margin. Changed some notes about
7575 maintainance of the ports in section 3.2.1 - is it OK like this?
7577 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7614 UPPER for immediate operands,
7615 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7617 * src/pic16/peeph.def: all peepholes with movff are commented out,
7618 because there is a problem in the pcode peep optimizer,
7619 * src/pic16/ralloc.c: the register allocator can now reuse local

7621 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7623 Added file src/pic16/NOTES with information about program writing on
7624 the current port version.

7633 * src/SDCCmain.c : fixed #872250: -l command line defined library
7634 files are scanned before standard library files
7636 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7656 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7659 * src/z80/main.c: added missed needLinkerScript flags (more than
7660 one port structure defined in these file)
7661 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7677 needLinkerScript flag
7679 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7680 * src/pic/glue.c: added variable udata_section_name to
7681 override default uninitialized data segment definition for
7682 devices only with SHAREBANK memory (reported from Erik Epetrich)
7683 * (pic14emitOverlay): modified to emit a commented overlay segment
7684 directive when no overlay data exist
7685 * (picglue): modified to emit uninitialized data segment
7686 according to udata_section_name

7692 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7693 object file from '.rel' to '.o' in port->linker structure,
7694 changed size of fptr from 2 to 3 in port structure
7696 2004-01-07 Borut Razem <borut.razem AT siol.net>
7698 * support/scripts/sdcc.nsi: update PATH
7699 * support/scripts/sdcc.ico: craeted

7712 include information about variables allocated to the overlay
7715 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7717 * as/mcs51/lkmain.c: Help about -Y option

7729 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7731 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7732 (default behaviour).
7734 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7736 A python script to validate compiler diagnostic messages. It can be
7737 used to verify that sdcc complains about bad c source code and
7738 gives a good location of the error.
7739 * support/valdiag/Makefile,
7740 * support/valdiag/valdiag.py,
7741 * support/valdiag/tests/*
7743 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7756 * src/common.h: added ifndef/define/endif macros
7757 around the header file.
7758 Bug reported from Jesus Calvino-Fraga
7760 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7762 * sdcc.spec: updated
7763 * device/include/Makefile.in: don't install CVS directories
7764 * device/lib/Makefile.in: added removal of CVS directories after install
7765 * doc/Makefile: fixed install, added local_icons
7766 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7767 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7768 * src/ds390/gen.c (genRightShift): fixed bug #870788
7769 * src/SDCCast.c (decorateType): fixed bug #870781
7771 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7773 PIC16 port related changes:
7774 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7775 added variable stackPos,
7777 * gen.c: genCall, assignResultValue: added support for
7778 pushing/retrieving function parameters to/from stack,
7779 genFunction,genEndFunction: setup stack frame for the
7781 genAddrOf: will be changed according to bug 863624
7783 * added files genutils.c and genutils.h which contain gen*
7784 debugged and optimised functions extracted from gen.c
7786 * glue.c: added variable 'externs' which holds extern symbols,
7787 pic16emitRegularMap: is modified to properly handle relocatable
7788 symbols under the new scheme,
7789 pic16createInterruptVect: is modified
7790 pic16printPublics: is modified to emit 'global' assembler directives,
7791 added pic16_printExterns to print extern symbols,
7792 pic16glue: initializes stack/frame pointer in the beginning of
7793 the assembly output. Temporary hack, will be corrected later,
7794 because gplink yet does not support stack and SDCC does not
7795 yet support a type of crt0.o object to create the final binary.
7797 * Removed many lines that contain 8051 legacy code.
7798 * The code is finally placed under a 'code' directive.
7799 * Added port specific options.
7801 * _process_pragma: simplified since now we do not need *special*
7802 include file to define SFR registers. But a separate header
7803 will be needed. This will be developed later.
7804 * _pic16_parseOptions: added, parses port specific options:
7805 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7806 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7807 --preplace-udata-with=
7809 * _pic16_setDefaultOptions: modified to initialize section names,
7810 but hack is temporarly out of order since it needs improvement.
7811 * _pic16_genAssemblerPreamble: configuration words are emitted by
7812 their address instead of their name. This part is incomplete and
7813 supports only the 18Fxx2 devices. Other devices will emit an error
7814 during assembly since they do not contain the same set of config
7816 * _pic16_genIVT: is modified,
7818 * pcode.c: added definitions for some hardware registers that are needed
7820 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7821 All PCI entries are updated. Now LFSR is supported.
7822 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7823 * added pic16_newpCodeOpLit2 to support instructions with
7824 two literal arguments
7825 * pic16_pCode2str: corrected code that emits assembler instructions
7826 with two literal operands and those that have an access bit modifier
7827 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7828 this fixes a bug which caused some labels to be lost, when an
7829 assembler directive was added, i.e. banksel,
7830 * pic16_FixRegisterBanking: improved logic that causes the insertion
7832 * InlineFunction: functions that are called once, are not any more
7833 inlined. This can be a port option in the future,
7835 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7837 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7838 hold the corresponding uninitialized symbols,
7839 * pic16_allocProcessorRegister: registers have explicit marked the
7841 * pic16_allocInternalRegister: registers are explicit marked as
7843 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7844 processing list, so bit registers were lost,
7847 * ralloc.h: added field 'accessBank' and original symbol operand
7848 in register definition,
7849 * removed the field isMapped from register definition,
7851 ** Several functions have been removed from various sources:
7852 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7853 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7854 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7855 pic16_assignRelocatableRegisters
7857 ** others have been introduced:
7858 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7859 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7861 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7863 * support/scripts/inc2h.pl: changed definition of BIT_AT
7864 to emit 'sbit at' instead of 'bit at'. This was a request.
7866 PIC16 port related preliminary changes:
7867 * gen.c: prefixed function popRegFromString with
7868 pic16_ and all references to it corrected
7869 * pcode.c: all pic16_pc_* hardware registers prefixed
7870 with underscore (_),
7871 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7872 * ralloc.c: newReg(): when register is REG_SFR then
7873 set address to rIdx,
7874 pic16_allocProcessorRegister(): marks register wasUsed=0
7875 pic16_writeUsedRegs(): added a call to assign processor
7876 registers via pic16_assignFixedRegisters
7878 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7880 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7881 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7882 variables in unused register banks. Also the SSEG is placed
7883 wherever there is enough space for it, and IDATA can be anywhere
7884 in internal RAM. For now compile using -Wl-Y[stack_size].
7885 The mem file is different for this option as well, since it
7886 makes no sense of talking about DSEG lenght.
7888 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7890 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7891 in certain cases, e.g. when ROM assignment, patch provided
7892 from Albert den Haan.
7894 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8922 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8924 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8926 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8928 Z80 and MCS51 linkers complaint if a public symbol is defined

8937 A few small changes that speed up the peephole optimizer.
8941 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8943 Try to make the peephole optimizer smarter by maintaining
8944 an association between the assembly source code and the
8945 iCodes that originated them. Put this information to use
8946 with a new peephole rule condition "notVolatile" so that
8947 the rules can be aggressive yet still safe.
8952 * src/mcs51/peeph.def
8954 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8958 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8959 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8960 if the left or right operand symbols have the accuse flag set.
8962 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8964 Changed the type of the result of the ! (NOT) operator to char;
8965 previously it returned the same type as the source. This allows
8966 us to eliminate all the genFloatNot functions (all of its target
8967 implementations were very buggy) since !float can use the same
8970 * src/SDCCicode.c (ast2iCode): ! returns char

8979 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8980 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8981 during interrupts. Ensure WSAVE is located at a shared bank address.
8982 2. Fixed page selection in some places
8983 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8984 the registers name strings.
8985 4. Fixed "signed / unsigned compare" compiler warnings.
8986 5. The PIC port manages its own allocation of the general purpose
8987 registers, but makes no attempt to reuse them. As a result when
8988 compiling it soon runs out of general purpose registers. Some
8989 additional code was added to the files pcode.c and device.c to walk
8990 through the function call tree and rename the registers so that they
9000 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9001 genPlus() & genMinus() when the result is the same as left or right

9007 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9009 Made bitfield a distinct type from bit so that bitfields
9010 convert as per ANSI C and bits retain their traditional
9011 boolean style behaviour. Implemented bitfield support in
9019 * src/ds390/gen.c: bit v bitfield split
9020 * src/z80/gen.c: New support for bitfields
9021 * support/regression/tests/bitfields.c: reenabled z80,
9024 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9026 Rules 246.x, 247.x relate to bitfields, the others speed up
9027 access to xdata mapped I/O devices.
9029 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9031 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9033 Cleaned up genPackBits and genUnpackBits and added two helper
9034 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9035 for literal assignments in genPackBits (thanks to Frieder for
9041 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9043 Fixed bug #748310 (pointer to function type mishandled when the
9044 function name is omitted). Also fixed a SIGSEGV when a function
9045 attribute (reentrant, etc) is used on a non-function or on a
9046 function but misplaced before the parameter list.
9048 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9050 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9073 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9075 Made the constant following the "interrupt" keyword optional. If
9076 omitted, the function will not automatically be given an entry
9077 in the interrupt vector table (similar to #pragma NOIV, but
9078 less syntacticly kludgy). The interrupt number is also now
9079 range checked. Also fixed a bug in the high order bit example

9520 condition and ignore commands.
9522 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9524 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9525 is in parts still quite out of date, I did changes as far as I felt makes sense
9526 for a non-native english speaker.
9527 Please feel free to add to the manual or to correct my changes.
9528 * doc/Makefile: undid touching the date of intermediate tex files.
9530 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9547 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9548 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9549 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9550 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9553 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9555 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9556 the regression tests I'm not brave enough to enable 245.b, 245.c
9557 * doc/sdccman.lyx: added latex preamble for hyperref package.
9558 Using pdflatex this will give you a hyperlinked pdf file with
9559 bookmarks. (prepend '%' before /usepackage if this breaks something)
9561 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9575 Applied patch from bug 737905 (renamed yylineo to mylineno):
9582 * src/pic16/pcode.c: Cleaned warnings
9583 * src/pic16/pcodeflow.c: Cleaned warnings
9584 * src/pic16/pcoderegs.c: Cleaned warnings

9595 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9597 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9599 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9600 it can be defined with CFLAGS when running configure
9601 * src/SDCCmain.c: fixed compiling + linking with object files
9603 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9605 * configure.in: configure for pic16 port,
9606 added --disable-pic16-port
9607 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9608 * src/SDCCmain.c: linkOptions is changed to set *,
9609 added if/endif conditional macros to remove options help
9610 messages from optionsTable when a port is not configured, added
9611 support for the PIc16 port in the ports table, when executing
9612 the compiler with no port specified on command line, a default
9613 port is selected with the new macro DEFAULT_PORT which is
9614 defined in port.h, in setDefaultOptions() linkOptions is removed
9615 from initialization assignment, since now it is a set,
9616 parseCmdLine uses setParseWithComma for linkOptions, in
9617 linkEdit() linkOptions are accessed with new function indexSet()
9618 which returns the i'th item of a set variable. See SDCCset.c, in
9619 linkEdit() when calling buildCmdLine(), added linkOptions as
9620 last argument. Now users can pass arguments to gplink via the
9621 -Wl option, main() uses pic16glue() to glue up pic16 programs
9622 * src/SDCCpeeph.c: various changes to support pic16

9631 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9633 * src/pic16/glue.c: commented out some error producing lines
9634 * src/pic16/main.c: __config directives are commented out to stop
9635 gpasm complaining and test the linkage with gplink, _linkCmd and
9636 _asmCmd changed to be more gplink and gpasm friendly
9637 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9638 produced an error when parsed, peep rule 12 is added to utilize
9639 movff, but it is commented out since the pCode does not support
9640 yet a command with 2 address arguments
9642 2003-05-18 <johan AT balder>
9644 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9645 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9664 on entry now. Add tbreak. Other enhancements and fixes for use
9667 2003-05-12 Borut Razem <borut.razem AT siol.net>
9669 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9671 2003-05-11 Borut Razem <borut.razem AT siol.net>
9673 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9674 the path of bin directory, so that PATH is the only env. variable, which has to be set
9675 in case of standard installation.
9676 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10705 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10707 * in \sdcc\as\mcs51\ changed these files in order to create an
10708 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10709 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10710 following files to include the previous two files: aslink.dsp,
10711 Makefile.aslink, Makefile.bcc, and Makefile.in.
10713 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10714 .adb instead of .cdb
10716 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10718 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10719 value from option --iram-size.
10721 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10723 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10726 2002-09-18 <wiml AT hhhh.org>
10728 * SDCClrange.h: exposed setFromRange() and setToRange()
10729 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10730 packRegsForAccUse() (bug 542397)
10731 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10732 multiple times and emitting the fetch operations more than once
10733 added aopGetUsesAcc() function to allow binary operators to
10734 fetch their operands in the correct order; made genMinus() emit
10735 compact code for X = LITERAL - Y
10737 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10738 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10739 sprintf() in line 1267.
10741 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10742 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10745 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10746 Changes to aslink (All the changes are marked with 'JCF'):
10748 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10751 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10752 area BSEG. Also moves, if possible, the DATA area down into the internal
10753 ram so more space is available.
10755 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10758 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10759 not bytes. Function summary() which creates a memory usage summary
10760 file with extension .mem. Reports of overlaping stack and small stack
10761 size. If the space for the stack is less than 16 bytes aslink trows a
10764 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10765 the 8051. Option 'y' for memory summary output file.
10767 Changes to sdcc (All the changes are marked with 'JCF'):
10769 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10771 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10772 overlaying area for it (uses RegBankUsed[4]).
10774 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10775 bank zero as used by default. By default aslink locates the stack
10776 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10777 the creation of the .mem file. Delegates the allocation of data area
10778 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10779 the begining of the stack area to aslink.
10781 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10782 glue() in SDCCglue.c creates an area for it.
10784 2002-09-03 Borut Razem <borut.razem AT siol.net>
10785 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10786 sdcc/src/pic/glue.c:
10787 introduced atexit() handler for teporay files removal in case of
10788 errors, assertions, ...
10790 2002-08-29 Borut Razem <borut.razem AT siol.net>
10791 * sdcc/support/cpp2/auto-host_vc_in.h:
10792 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10793 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10794 Maybe there is a similar problem with BORLANDC? It should be checked!
10796 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10797 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10798 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10799 was not executed, and the compiler (cl) launched a warning:
10800 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10802 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10803 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10805 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10806 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10808 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10809 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10810 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10811 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10812 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10813 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10814 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10815 - added Release configuration in VS projects
10816 - review of compiler an linker options
10817 - VC .exe files are generated in bin_vc directory, not to interfere
10818 with binaries generated from other projects (cygwin, mingw, bcc ...)
10820 * sdcc/src/yacc.dsp: added
10822 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10823 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10824 and insert the version number definitions from .version
10826 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10828 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10838 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10840 2002-08-10 Borut Razem <borut.razem AT siol.net>
10841 * src/SDCCmain.c (main):
10842 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10843 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10844 The consequence was that some temporary files were not removed.
10847 unification of code in functions tempfilename() and tempfile():
10848 function tempnam() is defined in Visual Studio 6.0 and .NET
10850 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10852 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10853 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10854 - removed compiler command line option /WX: Treats all warnings as errors
10855 - update a list of source files, included into the project
10857 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10858 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10859 changed project type to Generic Project so that can be correcly converted to VS.NET project
10861 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10863 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10867 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10868 added return 0 statements after assert() to make compiler happy
10870 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10871 added newline in the def file to keep MSC compiler satisfied
10873 * sdcc/src/z80/gen.c:
10874 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10875 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10876 - solved MSC error in function aopDump()
10878 * sdcc_vc.h: define PREFIX as "\\sdcc"
10880 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11053 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11055 * sdcc/src/SDCCloop.c:
11056 Previous fix was not good. basic blocks that have "break" or "return" are
11057 not really partof a loop , but live ranges used in these blocks should
