822 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
824 Enabled VPATH feature: changed nearly all Makefiles (149 files).
825 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
827 One basic decision: e.g. src/clean.mk includes further files. In order
828 to make this work there are two solutions:
829 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
830 run configure on them. This way they can use
831 'include $(srcdir)/port-clean.mk'
832 - always include clean.mk by the Makefile at the same level. To avoid
833 that `make clean` tries to include and build Makefile.dep the
834 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
835 implemented, because now even `make uninstall` doesn't create
836 Makefile.in. clean.mk could be eliminated by pasting it in
839 * debugger/mcs51/Makefile.in: build own objects from library sources
840 (SLIB, SDCC) in current directory
842 * configure, configure.in: renamed --disable-device-lib-build in
843 --disable-device-lib; added --enable-doc, the required tools are
844 searched by configure; added result message; the toolchain for the
845 belonging ports are now only built, if the port is enabled.
847 * support/regression/*: all output is written in directory gen, because
848 the fwk and ports directories don't livet in the build tree using vpath
850 * doc/sdccman.lyx: renamed --disable-device-lib-build to
851 --disable-device-lib, added --enable-doc, added section VPATH
853 * sim/ucsim/configure.in,
854 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
855 z80 are enabled by default
857 2006-04-24 Raphael Neider <rneider AT web.de>
859 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
860 to config word, "pic14_"-prefixed some extern functions
861 (pic14_emitConfigWord): emit __config directive(s) if assignment to
862 config word has been found
863 * src/pic/device.h: added prototypes
864 * src/pic/pcode.c: added "pic14_"-prefix where needed
865 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
867 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
869 (pic14emitRegularMap): ignore config words,
870 (pic14createInterruptVect): moved generating __config directives away
871 (picglue): have __config directives emitted

881 fixes #1469504 and #1474602,
882 (pCodeRegOptimizeRegUsage): fixed typo in comment
884 2006-04-24 Borut Razem <borut.razem AT siol.net>
886 * device/examples/main8051.c: deleted - it was removed from CVS
887 24.mar.2000 and after that modified 18.feb.2001, so it reappered

889 * src/SDCCalloc.h: deleted - it was removed from CVS
890 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1128 implemented patch 1120823 Thanks to Willy De la Court (normal
1129 interrupts need an interrupt number now if they are made critical),
1130 and enabled nesting of critical functions though not for gbz80
1131 (genCritical, genEndCritical): added functions
1132 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1133 * src/z80/mappings.i: added "ei" to all mappings

1142 2006-03-16 Raphael Neider <rneider AT web.de>
1144 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1145 the left operand is shorter than the result (c* = lit-c* + int),
1147 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1150 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1152 * src/.version: increased version number to 2.5.5
1153 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1154 linking is done manually in pic16 port's _linkEdit,
1155 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1156 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1157 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1158 allocate asmop as AOP_ACC,
1159 (aopForRemat): added parameter 'bool result' in function declaration,
1160 (pic16_aopGet): return AOP_ACC when accessing WREG,
1161 (pic16_popGetTempReg): minor modification,
1162 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1163 'pic16_allocWithIdx',

1170 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1172 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1173 call to allocReg, not by manually allocating a new one,
1174 (pic16_assignRegisters): now before going through the register
1175 allocating functions mark all registers as free. This eliminates some
1176 side effects resulting from peephole parser done earlier in the backbone
1178 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1200 (aopForSym, aopOp): increment asmop.allocated if reused,
1201 (freeAsmop): decrement asmop.allocated and check for zero instead of
1203 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1204 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1228 2006-03-06 Borut Razem <borut.razem AT siol.net>
1230 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1231 made the linker quiet
1233 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1235 * src/pic16/gen.c (genPcall): fixed bug #1443644
1236 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1237 which dumps before the function entry point a data byte which represents
1238 the number of the local variables used by the specified function, added
1239 'xinst' for initial support for Extended Instruction Support,
1240 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1241 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1242 port->fun_prefix anymore (may change later),
1243 (genFunction, genEndFunction): do not store/restore local registers for
1244 _main (this should take care the --main-return command line option in
1246 (genOr): removed some legacy pic-port instructions,
1247 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1248 performing operations with SFR's causes data to be written more than
1249 once to each SFR. Perhaps SFRs should be handled in special cases...
1250 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1252 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1253 into account for stack starting position,
1254 (struct OPTIONS pic16_optionsTable): added command line argument
1255 --extended or -y for Extended Instruction Support,
1256 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1257 (deassignLRs): *** perhaps the most important change, old 'for' code
1258 (commented out for reference), didn't account for some registers which
1259 were left marked 'not free' after a pointer operation. The change
1260 reduces register usage a lot in some cases
1262 2006-03-04 Borut Razem <borut.razem AT siol.net>
1264 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3529 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3531 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3535 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3536 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3537 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3538 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3539 always available in leading double underscore form. The C99 support is
3540 mostly missing, but it's a start.
3541 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3542 reserved identifier "__data".
3544 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3588 immedDom() returning wrong block; probably fixes bug #1160833)
3590 2005-03-20 Borut Razem <borut.razem AT siol.net>
3592 * support/scripts/inc2h.pl: WIN32 port

3620 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3622 * device/lib/printf_large.c: removed inline assembly for portability and
3623 readability. Use printf_fast if speed or size are more important.
3624 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3625 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3627 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3629 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3630 prevent compiler warning
3632 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3634 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3635 moved to level 0 and declared as static. Also they are explicit
3636 placed in access bank. This was necessery because some times they
3637 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3638 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3639 optimizations. Currently only compare to unsigned char is implemented,
3640 * src/pic16/gen.c: added fReturnIdx array,
3641 * (struct resolvedIfx) is moved to gen.h and made public,
3642 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3643 * (aopForSym): added an optimization to directly store in stack of
3644 the operand of a SEND iCode,
3645 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3646 but as registers instead (AOP_REG) using the fReturnIdx array,
3647 * (pic16_freeAsmop): remove the freed register from the
3648 _G.sregsAlloc field,
3649 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3650 a compare of 'WREG',
3651 * (pic16_popGetTempRegCond): changed function prototype, now
3652 function takes also a bitVector argument v which holds the current
3653 set of registers that are allocated for stack access by aopForSym,
3654 registers allocated in aopForSym for accessing stack symbols are not
3655 any more part of the functions usedRegs field,
3656 * (genCall): some times aopOp is called for a stack variable to be
3657 send, aopForSym might perform the push, if this is true make sure
3658 that genCall doesn't push the variable twice by testing _G.resDirect,
3659 * (genFunction): changed testing for unspecified interrupt number
3660 from 256 to INTNO_UNSPEC,
3661 * modified selection scheme of frame pointer generation. Previously
3662 if function did use local registers a frame pointer was generated,
3663 now a frame pointer is generated only if function has arguments
3664 (that need PLUSW2 register access), or has stack arguments, or the
3665 compiler is not instructed to omit the frame pointer,
3666 * (genEndFunction): before restoring local registers that were saved
3667 in the function preamble, also restore the registers that *might*
3668 have been allocated for stack access,
3669 * (genRet): removed some old comments,
3670 * (genCmp, the active (RN's) version): added a call to the
3671 pic16_genCmp_special function to perform the compare with a more
3672 robust and optimized way,
3673 * (genInline): a feature has been added in inline code generation,
3674 which allows a wildcard variable substitution when writing inline
3675 assembly. Code is incomplete and experimental therefore undocumented,
3676 * (genCast): changed order of aopOp for result and right to allow
3677 aopForSym to directly load the result if possible,
3678 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3679 perform an optimized compare on some selected special occasions,
3680 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3681 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3682 generate an IVT any more,
3683 * src/pic16/main.c (pic16_optionsTable): added command line option
3685 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3686 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3688 * src/pic16/NOTES: Raphael Neider added in list of active developers
3689 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3690 jumptable_end to prevent bug #,
3691 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3692 inCond and outCond fields,
3693 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3694 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3695 turn off register spilling,
3696 * (packRegsForOneUse): synced with other ports' versions although it
3697 is not used currently,
3698 * (pic16_packRegisters): added an optimization while reading
3699 structure bitfields, some registers may be saved (malloc code is
3700 decreased by 80 bytes)
3702 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3704 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3705 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3706 this can be optimized more?
3708 2005-03-10 Raphael Neider <rneider AT web.de>
3710 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3711 genNearPointerGet): (hopefully) fixed access to bitfields via
3712 pointers (p->bitN = x; and x = p->bitN; failed)
3714 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3757 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3758 to keep the correct label reference count when adding/removing references
3759 to labels. A peephole file using this is appended to patch #1144962.

3891 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3892 (sizeof(sectNames) changed to sizeof(sectName))

3900 of (byte sized) temporaries (assign them to WREG for now)
3901 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3902 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3903 this might fix SIGSEGVs on MinGW...
3904 * src/SDCCopt.c (killDeadCode): restored original behaviour
3905 (volatile operands might get thrown away though)

4333 comparisons, and supports quoted literals
4334 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
4336 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4344 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4346 Adding support for replacing ljmps with sjmps in jumptables
4347 generated for switch statements. For now you need to set the
4348 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4349 Now 4 algorithms for mcs51 jumptable generation are used:
4350 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4351 addresses loaded pc-relative for up to 112 cases and stack-pushing
4352 target addresses loaded with offset from dptr for up to 256 cases.
4354 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4355 * src/mcs51/main.c: adapted constants for switch table generation
4356 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

4376 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4378 Large cummulative patch for pic16 port.
4379 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4380 to call when a stack overflow occurs,
4381 * (malloc.h): added CVS Id tag,
4382 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4384 * added libc directory. The current version of LibC contains string
4385 functions, ctype functions and macros and some functions of the
4386 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4387 be extensively tested in the future. Standard disclaimer here.
4388 Library is not automatically build yet. But one can build it by
4389 invoking 'make' inside the libc directory.
4390 * added ADC library under libio. Preliminary version yet.
4392 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4393 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4394 aopForRemat() now and not by pic16_aopOp(),
4395 * (pic16_popGetTempReg): removed warning messgae when allocating
4396 temporary registers, its a buggy feature and will be removed,
4397 * (pic16_popGet): set register instance field in AOP_CRY,
4398 * (pic16_outBitC): fixed for results in size greater than 1,
4399 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4400 * (pic16_storeForReturn): optimized return of 0,
4401 * (genCmp): experimental code for new genCmp which uses PIC18's
4402 special compare&skip instructions. Initial tests fail some times
4403 with variables grater than 1 byte in size, so new code is disabled,
4404 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4406 * (genCast): began a fix to optimize the casting of a bit to another
4407 bit, now assigning a bitfield to another bitfield will fail, sorry,
4408 * src/pic16/main.c: disabled the use of lr-support feature,
4409 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4410 * added some function prototypes, added function _debugf prototype,
4411 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4412 bits with offset (case PO_GPR_BIT),
4413 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4415 * (isBankInstruction): modified to return 0 for no banking instruction,
4416 and 1 for banking instruction,
4417 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4418 caused stop processing pCodes after a inline assembly block,
4419 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4420 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4421 registers when it shouldn't,
4422 * src/pic16/ralloc.c (allocReg): add preliminary support for
4423 supporting a limited set of temporary registers,
4425 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4427 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4428 genDataPointerSet): ensure assignments always copy in MSB to LSB
4430 (loadRegFromAop): recognize CLRH optimization,
4431 (genFunction): optimize RECEIVE iCodes in reentrant functions
4433 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4435 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4436 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4438 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4444 * device/lib/_gptrget.c (_gptrget),
4445 * device/lib/_gptrgetc.c (_gptrgetc),
4446 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4447 instead of sjmp to ret
4448 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4449 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4451 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7433 loaded with the linker search paths (-L arguments) and the libraries
7434 to be linked with the current source (-l arguments). Changes
7435 currently will affect only the pic16 port.
7436 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7437 include path the port specific paths and port specific libraries,
7438 * gplink command now contains the $3 argument,
7439 * src/pic16/device.h,
7440 * src/pic16/device.c,: structure PIC_device is made public and
7441 renamed to PIC16_device, the same for variable Pics which is renamed
7442 to Pics16. Updated all references to them.
7443 * src/pic16/glue.c (pic16glue): corrected bug with code
7444 initialization which bypassed the variable initializations block.
7446 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7447 COMPILE_FLAGS and added the --nostdinc option
7449 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7451 * device/include/mc68hc908jb8.h: Register defs for another member
7452 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7454 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7456 Documenting changes from previous commits.
7457 * configure.in (version 1.56),
7458 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7459 when generating output files to configure the pic16 library,
7460 but now I've commented it out, since gputils aren't installed in the
7461 SF compile farm, so library won't compile
7463 * device/lib/Makefile.in (version 1.56): initially I've added in
7464 target 'all' the prerequestive 'model-pic16' so it compiled the
7465 pic16 library, but now I've commented it out for the same reasons
7467 * added targets 'model-pic16' and 'objects-pic16' to compile the
7469 * added target 'port-specific-objects-pic16' to handle the
7470 generated libraries and copy them into the build/ directory
7471 * added target 'clean-intermediate-pic16' to clean intermediate
7472 files into pic16 directory
7473 * in target 'installdirs' added line to create directory pic16 in
7474 the installation path
7476 * device/include/Makefile.in (version 1.11): in target 'install'
7477 added lines to copy all header files to installation path,
7478 * in target 'installdirs' added line create directory for pic16
7479 headers in the installation path

7494 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7495 option so that it actually works. Made it specific to the z80, since
7496 the gbz80 doesn't have these kinds of I/O ports.
7498 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7500 * device/include/z180.h,

7513 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7515 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7516 changed interrupt vector table generation to only emit declared vectors.

7522 Mainly changes to support compilation of the device libraries
7523 * src/pic16/device.c: stack is allocated via symbol and not
7524 via literal number. The symbol is placed in the corresponding
7525 position of the data ram
7526 * (pic16_dump_section): relocatable and absolute uninitialized
7527 data are now emitted in sorted order to reduce section naming,
7528 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7529 weren't marked as being in the access bank,
7531 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7533 Added portion of GNU PIC Library under the directory
7534 device/include/pic16 and device/lib/pic16. These files
7535 contain the declarations of SFRs for the PIC18Fxx2 devices.
7536 The directory is initialized via configure from toplevel.
7538 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7540 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7541 the spilllocations to be compared correctly
7543 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7545 * src/SDCCast.c (decorateType): fixed bug introduced today
7547 2004-01-12 Borut Razem <borut.razem AT siol.net>

7565 * doc/sdccman.lyx: Moved and added some sections, small changes
7566 all over. Telling LaTeX to be less strict with word spacing
7567 to better keep the right margin. Changed some notes about
7568 maintainance of the ports in section 3.2.1 - is it OK like this?
7570 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7607 UPPER for immediate operands,
7608 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7610 * src/pic16/peeph.def: all peepholes with movff are commented out,
7611 because there is a problem in the pcode peep optimizer,
7612 * src/pic16/ralloc.c: the register allocator can now reuse local
7613 function symbols for another function. This saves register usage.
7614 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7616 Added file src/pic16/NOTES with information about program writing on
7617 the current port version.

7649 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7652 * src/z80/main.c: added missed needLinkerScript flags (more than
7653 one port structure defined in these file)
7654 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7670 needLinkerScript flag
7672 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7673 * src/pic/glue.c: added variable udata_section_name to
7674 override default uninitialized data segment definition for
7675 devices only with SHAREBANK memory (reported from Erik Epetrich)
7676 * (pic14emitOverlay): modified to emit a commented overlay segment
7677 directive when no overlay data exist
7678 * (picglue): modified to emit uninitialized data segment
7679 according to udata_section_name

7689 2004-01-07 Borut Razem <borut.razem AT siol.net>
7691 * support/scripts/sdcc.nsi: update PATH
7692 * support/scripts/sdcc.ico: craeted

7705 include information about variables allocated to the overlay
7708 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7710 * as/mcs51/lkmain.c: Help about -Y option

7722 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7724 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7725 (default behaviour).
7727 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7729 A python script to validate compiler diagnostic messages. It can be
7730 used to verify that sdcc complains about bad c source code and
7731 gives a good location of the error.
7732 * support/valdiag/Makefile,
7733 * support/valdiag/valdiag.py,
7734 * support/valdiag/tests/*
7736 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7749 * src/common.h: added ifndef/define/endif macros
7750 around the header file.
7751 Bug reported from Jesus Calvino-Fraga
7753 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7755 * sdcc.spec: updated
7756 * device/include/Makefile.in: don't install CVS directories
7757 * device/lib/Makefile.in: added removal of CVS directories after install
7758 * doc/Makefile: fixed install, added local_icons
7759 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7760 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7761 * src/ds390/gen.c (genRightShift): fixed bug #870788
7762 * src/SDCCast.c (decorateType): fixed bug #870781
7764 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7766 PIC16 port related changes:
7767 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7768 added variable stackPos,
7770 * gen.c: genCall, assignResultValue: added support for
7771 pushing/retrieving function parameters to/from stack,
7772 genFunction,genEndFunction: setup stack frame for the
7774 genAddrOf: will be changed according to bug 863624
7776 * added files genutils.c and genutils.h which contain gen*
7777 debugged and optimised functions extracted from gen.c
7779 * glue.c: added variable 'externs' which holds extern symbols,
7780 pic16emitRegularMap: is modified to properly handle relocatable
7781 symbols under the new scheme,
7782 pic16createInterruptVect: is modified
7783 pic16printPublics: is modified to emit 'global' assembler directives,
7784 added pic16_printExterns to print extern symbols,
7785 pic16glue: initializes stack/frame pointer in the beginning of
7786 the assembly output. Temporary hack, will be corrected later,
7787 because gplink yet does not support stack and SDCC does not
7788 yet support a type of crt0.o object to create the final binary.
7790 * Removed many lines that contain 8051 legacy code.
7791 * The code is finally placed under a 'code' directive.
7792 * Added port specific options.
7794 * _process_pragma: simplified since now we do not need *special*
7795 include file to define SFR registers. But a separate header
7796 will be needed. This will be developed later.
7797 * _pic16_parseOptions: added, parses port specific options:
7798 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7799 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7800 --preplace-udata-with=
7802 * _pic16_setDefaultOptions: modified to initialize section names,
7803 but hack is temporarly out of order since it needs improvement.
7804 * _pic16_genAssemblerPreamble: configuration words are emitted by
7805 their address instead of their name. This part is incomplete and
7806 supports only the 18Fxx2 devices. Other devices will emit an error
7807 during assembly since they do not contain the same set of config
7809 * _pic16_genIVT: is modified,
7811 * pcode.c: added definitions for some hardware registers that are needed
7813 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7814 All PCI entries are updated. Now LFSR is supported.
7815 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7816 * added pic16_newpCodeOpLit2 to support instructions with
7817 two literal arguments
7818 * pic16_pCode2str: corrected code that emits assembler instructions
7819 with two literal operands and those that have an access bit modifier
7820 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7821 this fixes a bug which caused some labels to be lost, when an
7822 assembler directive was added, i.e. banksel,
7823 * pic16_FixRegisterBanking: improved logic that causes the insertion
7825 * InlineFunction: functions that are called once, are not any more
7826 inlined. This can be a port option in the future,
7828 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7830 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7831 hold the corresponding uninitialized symbols,
7832 * pic16_allocProcessorRegister: registers have explicit marked the
7834 * pic16_allocInternalRegister: registers are explicit marked as
7836 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7837 processing list, so bit registers were lost,
7840 * ralloc.h: added field 'accessBank' and original symbol operand
7841 in register definition,
7842 * removed the field isMapped from register definition,
7844 ** Several functions have been removed from various sources:
7845 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7846 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7847 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7848 pic16_assignRelocatableRegisters
7850 ** others have been introduced:
7851 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7852 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7854 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7856 * support/scripts/inc2h.pl: changed definition of BIT_AT
7857 to emit 'sbit at' instead of 'bit at'. This was a request.
7859 PIC16 port related preliminary changes:
7860 * gen.c: prefixed function popRegFromString with
7861 pic16_ and all references to it corrected
7862 * pcode.c: all pic16_pc_* hardware registers prefixed
7863 with underscore (_),
7864 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7865 * ralloc.c: newReg(): when register is REG_SFR then
7866 set address to rIdx,
7867 pic16_allocProcessorRegister(): marks register wasUsed=0
7868 pic16_writeUsedRegs(): added a call to assign processor
7869 registers via pic16_assignFixedRegisters
7871 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7873 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7874 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7875 variables in unused register banks. Also the SSEG is placed
7876 wherever there is enough space for it, and IDATA can be anywhere
7877 in internal RAM. For now compile using -Wl-Y[stack_size].
7878 The mem file is different for this option as well, since it
7879 makes no sense of talking about DSEG lenght.
7881 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7883 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7884 in certain cases, e.g. when ROM assignment, patch provided
7885 from Albert den Haan.
7887 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8930 A few small changes that speed up the peephole optimizer.
8934 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8936 Try to make the peephole optimizer smarter by maintaining
8937 an association between the assembly source code and the
8938 iCodes that originated them. Put this information to use
8939 with a new peephole rule condition "notVolatile" so that
8940 the rules can be aggressive yet still safe.
8945 * src/mcs51/peeph.def
8947 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8951 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8952 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8953 if the left or right operand symbols have the accuse flag set.
8955 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8957 Changed the type of the result of the ! (NOT) operator to char;
8958 previously it returned the same type as the source. This allows
8959 us to eliminate all the genFloatNot functions (all of its target
8960 implementations were very buggy) since !float can use the same
8963 * src/SDCCicode.c (ast2iCode): ! returns char

8972 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8973 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8974 during interrupts. Ensure WSAVE is located at a shared bank address.
8975 2. Fixed page selection in some places
8976 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8977 the registers name strings.
8978 4. Fixed "signed / unsigned compare" compiler warnings.
8979 5. The PIC port manages its own allocation of the general purpose
8980 registers, but makes no attempt to reuse them. As a result when
8981 compiling it soon runs out of general purpose registers. Some
8982 additional code was added to the files pcode.c and device.c to walk
8983 through the function call tree and rename the registers so that they
8993 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8994 genPlus() & genMinus() when the result is the same as left or right

9000 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9002 Made bitfield a distinct type from bit so that bitfields
9003 convert as per ANSI C and bits retain their traditional
9004 boolean style behaviour. Implemented bitfield support in
9012 * src/ds390/gen.c: bit v bitfield split
9013 * src/z80/gen.c: New support for bitfields
9014 * support/regression/tests/bitfields.c: reenabled z80,
9017 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9019 Rules 246.x, 247.x relate to bitfields, the others speed up
9020 access to xdata mapped I/O devices.
9022 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9024 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9026 Cleaned up genPackBits and genUnpackBits and added two helper
9027 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9028 for literal assignments in genPackBits (thanks to Frieder for
9034 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9036 Fixed bug #748310 (pointer to function type mishandled when the
9037 function name is omitted). Also fixed a SIGSEGV when a function
9038 attribute (reentrant, etc) is used on a non-function or on a
9039 function but misplaced before the parameter list.
9041 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9043 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9066 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9068 Made the constant following the "interrupt" keyword optional. If
9069 omitted, the function will not automatically be given an entry
9070 in the interrupt vector table (similar to #pragma NOIV, but
9071 less syntacticly kludgy). The interrupt number is also now
9072 range checked. Also fixed a bug in the high order bit example

9513 condition and ignore commands.
9515 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9517 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9518 is in parts still quite out of date, I did changes as far as I felt makes sense
9519 for a non-native english speaker.
9520 Please feel free to add to the manual or to correct my changes.
9521 * doc/Makefile: undid touching the date of intermediate tex files.
9523 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9538 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9540 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9541 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9542 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9543 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9546 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9548 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9549 the regression tests I'm not brave enough to enable 245.b, 245.c
9550 * doc/sdccman.lyx: added latex preamble for hyperref package.
9551 Using pdflatex this will give you a hyperlinked pdf file with
9552 bookmarks. (prepend '%' before /usepackage if this breaks something)
9554 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9568 Applied patch from bug 737905 (renamed yylineo to mylineno):
9575 * src/pic16/pcode.c: Cleaned warnings
9576 * src/pic16/pcodeflow.c: Cleaned warnings

9590 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9592 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9593 it can be defined with CFLAGS when running configure
9594 * src/SDCCmain.c: fixed compiling + linking with object files
9596 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9598 * configure.in: configure for pic16 port,
9599 added --disable-pic16-port
9600 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9601 * src/SDCCmain.c: linkOptions is changed to set *,
9602 added if/endif conditional macros to remove options help
9603 messages from optionsTable when a port is not configured, added
9604 support for the PIc16 port in the ports table, when executing
9605 the compiler with no port specified on command line, a default
9606 port is selected with the new macro DEFAULT_PORT which is
9607 defined in port.h, in setDefaultOptions() linkOptions is removed
9608 from initialization assignment, since now it is a set,
9609 parseCmdLine uses setParseWithComma for linkOptions, in
9610 linkEdit() linkOptions are accessed with new function indexSet()
9611 which returns the i'th item of a set variable. See SDCCset.c, in
9612 linkEdit() when calling buildCmdLine(), added linkOptions as
9613 last argument. Now users can pass arguments to gplink via the
9614 -Wl option, main() uses pic16glue() to glue up pic16 programs
9615 * src/SDCCpeeph.c: various changes to support pic16
9616 * src/SDCCset.c: added function void *indexSet(set *, int) to
9617 return the i'th item of the set

9620 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9621 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9622 added macro DEFAULT_PORT
9623 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9624 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9626 * src/pic16/glue.c: commented out some error producing lines
9627 * src/pic16/main.c: __config directives are commented out to stop
9628 gpasm complaining and test the linkage with gplink, _linkCmd and
9629 _asmCmd changed to be more gplink and gpasm friendly
9630 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9631 produced an error when parsed, peep rule 12 is added to utilize
9632 movff, but it is commented out since the pCode does not support
9633 yet a command with 2 address arguments
9635 2003-05-18 <johan AT balder>
9637 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9638 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9657 on entry now. Add tbreak. Other enhancements and fixes for use
9660 2003-05-12 Borut Razem <borut.razem AT siol.net>
9662 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9664 2003-05-11 Borut Razem <borut.razem AT siol.net>
9666 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9667 the path of bin directory, so that PATH is the only env. variable, which has to be set
9668 in case of standard installation.
9669 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10698 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10700 * in \sdcc\as\mcs51\ changed these files in order to create an
10701 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10702 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10703 following files to include the previous two files: aslink.dsp,
10704 Makefile.aslink, Makefile.bcc, and Makefile.in.
10706 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10707 .adb instead of .cdb
10709 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10711 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10712 value from option --iram-size.
10714 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10716 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10719 2002-09-18 <wiml AT hhhh.org>
10721 * SDCClrange.h: exposed setFromRange() and setToRange()
10722 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10723 packRegsForAccUse() (bug 542397)
10724 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10725 multiple times and emitting the fetch operations more than once
10726 added aopGetUsesAcc() function to allow binary operators to
10727 fetch their operands in the correct order; made genMinus() emit
10728 compact code for X = LITERAL - Y
10730 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10731 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10732 sprintf() in line 1267.
10734 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10735 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10738 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10739 Changes to aslink (All the changes are marked with 'JCF'):
10741 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10744 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10745 area BSEG. Also moves, if possible, the DATA area down into the internal
10746 ram so more space is available.
10748 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10751 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10752 not bytes. Function summary() which creates a memory usage summary
10753 file with extension .mem. Reports of overlaping stack and small stack
10754 size. If the space for the stack is less than 16 bytes aslink trows a
10757 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10758 the 8051. Option 'y' for memory summary output file.
10760 Changes to sdcc (All the changes are marked with 'JCF'):
10762 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10764 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10765 overlaying area for it (uses RegBankUsed[4]).
10767 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10768 bank zero as used by default. By default aslink locates the stack
10769 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10770 the creation of the .mem file. Delegates the allocation of data area
10771 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10772 the begining of the stack area to aslink.
10774 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10775 glue() in SDCCglue.c creates an area for it.
10777 2002-09-03 Borut Razem <borut.razem AT siol.net>
10778 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10779 sdcc/src/pic/glue.c:
10780 introduced atexit() handler for teporay files removal in case of
10781 errors, assertions, ...
10783 2002-08-29 Borut Razem <borut.razem AT siol.net>
10784 * sdcc/support/cpp2/auto-host_vc_in.h:
10785 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10786 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10787 Maybe there is a similar problem with BORLANDC? It should be checked!
10789 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10790 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10791 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10792 was not executed, and the compiler (cl) launched a warning:
10793 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10795 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10796 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10802 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10803 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10804 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10805 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10806 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10807 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10808 - added Release configuration in VS projects
10809 - review of compiler an linker options
10810 - VC .exe files are generated in bin_vc directory, not to interfere
10811 with binaries generated from other projects (cygwin, mingw, bcc ...)
10813 * sdcc/src/yacc.dsp: added
10815 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10816 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10817 and insert the version number definitions from .version
10819 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10821 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10833 2002-08-10 Borut Razem <borut.razem AT siol.net>
10834 * src/SDCCmain.c (main):
10835 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10836 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10837 The consequence was that some temporary files were not removed.
10840 unification of code in functions tempfilename() and tempfile():
10841 function tempnam() is defined in Visual Studio 6.0 and .NET
10843 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10845 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10846 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

10851 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10852 changed project type to Generic Project so that can be correcly converted to VS.NET project

10860 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10861 added return 0 statements after assert() to make compiler happy
10863 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10864 added newline in the def file to keep MSC compiler satisfied
10866 * sdcc/src/z80/gen.c:
10867 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10868 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10869 - solved MSC error in function aopDump()
10871 * sdcc_vc.h: define PREFIX as "\\sdcc"

11046 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11048 * sdcc/src/SDCCloop.c:
11049 Previous fix was not good. basic blocks that have "break" or "return" are
11050 not really partof a loop , but live ranges used in these blocks should
