855 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
857 Enabled VPATH feature: changed nearly all Makefiles (149 files).
858 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
860 One basic decision: e.g. src/clean.mk includes further files. In order
861 to make this work there are two solutions:
862 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
863 run configure on them. This way they can use
864 'include $(srcdir)/port-clean.mk'
865 - always include clean.mk by the Makefile at the same level. To avoid
866 that `make clean` tries to include and build Makefile.dep the
867 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
868 implemented, because now even `make uninstall` doesn't create
869 Makefile.in. clean.mk could be eliminated by pasting it in
872 * debugger/mcs51/Makefile.in: build own objects from library sources
873 (SLIB, SDCC) in current directory
875 * configure, configure.in: renamed --disable-device-lib-build in
876 --disable-device-lib; added --enable-doc, the required tools are
877 searched by configure; added result message; the toolchain for the
878 belonging ports are now only built, if the port is enabled.
880 * support/regression/*: all output is written in directory gen, because
881 the fwk and ports directories don't livet in the build tree using vpath
883 * doc/sdccman.lyx: renamed --disable-device-lib-build to
884 --disable-device-lib, added --enable-doc, added section VPATH
886 * sim/ucsim/configure.in,
887 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
888 z80 are enabled by default
890 2006-04-24 Raphael Neider <rneider AT web.de>
892 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
893 to config word, "pic14_"-prefixed some extern functions
894 (pic14_emitConfigWord): emit __config directive(s) if assignment to
895 config word has been found
896 * src/pic/device.h: added prototypes
897 * src/pic/pcode.c: added "pic14_"-prefix where needed
898 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
900 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
902 (pic14emitRegularMap): ignore config words,
903 (pic14createInterruptVect): moved generating __config directives away
904 (picglue): have __config directives emitted

914 fixes #1469504 and #1474602,
915 (pCodeRegOptimizeRegUsage): fixed typo in comment
917 2006-04-24 Borut Razem <borut.razem AT siol.net>
919 * device/examples/main8051.c: deleted - it was removed from CVS
920 24.mar.2000 and after that modified 18.feb.2001, so it reappered
921 after the transition to Subversion
922 * src/SDCCalloc.h: deleted - it was removed from CVS
923 3.feb.2001 and after that modified 18.feb.2001, so it reappered
924 after the transition to Subversion

1161 implemented patch 1120823 Thanks to Willy De la Court (normal
1162 interrupts need an interrupt number now if they are made critical),
1163 and enabled nesting of critical functions though not for gbz80
1164 (genCritical, genEndCritical): added functions
1165 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1166 * src/z80/mappings.i: added "ei" to all mappings

1178 the left operand is shorter than the result (c* = lit-c* + int),
1180 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1183 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1185 * src/.version: increased version number to 2.5.5
1186 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1187 linking is done manually in pic16 port's _linkEdit,
1188 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1189 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1190 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1191 allocate asmop as AOP_ACC,
1192 (aopForRemat): added parameter 'bool result' in function declaration,
1193 (pic16_aopGet): return AOP_ACC when accessing WREG,
1194 (pic16_popGetTempReg): minor modification,

1205 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1206 call to allocReg, not by manually allocating a new one,
1207 (pic16_assignRegisters): now before going through the register
1208 allocating functions mark all registers as free. This eliminates some
1209 side effects resulting from peephole parser done earlier in the backbone
1211 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1269 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1270 which dumps before the function entry point a data byte which represents
1271 the number of the local variables used by the specified function, added
1272 'xinst' for initial support for Extended Instruction Support,
1273 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1274 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1275 port->fun_prefix anymore (may change later),
1276 (genFunction, genEndFunction): do not store/restore local registers for
1277 _main (this should take care the --main-return command line option in
1279 (genOr): removed some legacy pic-port instructions,
1280 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1281 performing operations with SFR's causes data to be written more than
1282 once to each SFR. Perhaps SFRs should be handled in special cases...
1283 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1285 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1286 into account for stack starting position,

1288 --extended or -y for Extended Instruction Support,
1289 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1290 (deassignLRs): *** perhaps the most important change, old 'for' code
1291 (commented out for reference), didn't account for some registers which
1292 were left marked 'not free' after a pointer operation. The change
1293 reduces register usage a lot in some cases
1295 2006-03-04 Borut Razem <borut.razem AT siol.net>

3570 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3571 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3572 always available in leading double underscore form. The C99 support is
3573 mostly missing, but it's a start.
3574 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3655 * device/lib/printf_large.c: removed inline assembly for portability and
3656 readability. Use printf_fast if speed or size are more important.
3657 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3658 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3660 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3662 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3663 prevent compiler warning
3665 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3667 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3668 moved to level 0 and declared as static. Also they are explicit
3669 placed in access bank. This was necessery because some times they
3670 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3671 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3672 optimizations. Currently only compare to unsigned char is implemented,
3673 * src/pic16/gen.c: added fReturnIdx array,
3674 * (struct resolvedIfx) is moved to gen.h and made public,
3675 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3676 * (aopForSym): added an optimization to directly store in stack of
3677 the operand of a SEND iCode,
3678 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3679 but as registers instead (AOP_REG) using the fReturnIdx array,
3680 * (pic16_freeAsmop): remove the freed register from the
3681 _G.sregsAlloc field,
3682 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3683 a compare of 'WREG',
3684 * (pic16_popGetTempRegCond): changed function prototype, now
3685 function takes also a bitVector argument v which holds the current
3686 set of registers that are allocated for stack access by aopForSym,
3687 registers allocated in aopForSym for accessing stack symbols are not
3688 any more part of the functions usedRegs field,
3689 * (genCall): some times aopOp is called for a stack variable to be
3690 send, aopForSym might perform the push, if this is true make sure
3691 that genCall doesn't push the variable twice by testing _G.resDirect,
3692 * (genFunction): changed testing for unspecified interrupt number
3693 from 256 to INTNO_UNSPEC,
3694 * modified selection scheme of frame pointer generation. Previously
3695 if function did use local registers a frame pointer was generated,
3696 now a frame pointer is generated only if function has arguments
3697 (that need PLUSW2 register access), or has stack arguments, or the
3698 compiler is not instructed to omit the frame pointer,
3699 * (genEndFunction): before restoring local registers that were saved
3700 in the function preamble, also restore the registers that *might*
3701 have been allocated for stack access,
3702 * (genRet): removed some old comments,
3703 * (genCmp, the active (RN's) version): added a call to the
3704 pic16_genCmp_special function to perform the compare with a more
3705 robust and optimized way,
3706 * (genInline): a feature has been added in inline code generation,
3707 which allows a wildcard variable substitution when writing inline
3708 assembly. Code is incomplete and experimental therefore undocumented,
3709 * (genCast): changed order of aopOp for result and right to allow
3710 aopForSym to directly load the result if possible,
3711 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3712 perform an optimized compare on some selected special occasions,
3713 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3714 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3715 generate an IVT any more,
3716 * src/pic16/main.c (pic16_optionsTable): added command line option
3718 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3719 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3721 * src/pic16/NOTES: Raphael Neider added in list of active developers
3722 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3723 jumptable_end to prevent bug #,
3724 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3725 inCond and outCond fields,
3726 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3727 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3728 turn off register spilling,
3729 * (packRegsForOneUse): synced with other ports' versions although it
3730 is not used currently,
3731 * (pic16_packRegisters): added an optimization while reading
3732 structure bitfields, some registers may be saved (malloc code is
3733 decreased by 80 bytes)
3735 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3737 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3738 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3739 this can be optimized more?
3741 2005-03-10 Raphael Neider <rneider AT web.de>
3743 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3744 genNearPointerGet): (hopefully) fixed access to bitfields via
3745 pointers (p->bitN = x; and x = p->bitN; failed)

4379 Adding support for replacing ljmps with sjmps in jumptables
4380 generated for switch statements. For now you need to set the
4381 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4382 Now 4 algorithms for mcs51 jumptable generation are used:
4383 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4384 addresses loaded pc-relative for up to 112 cases and stack-pushing
4385 target addresses loaded with offset from dptr for up to 256 cases.
4387 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

4412 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4413 to call when a stack overflow occurs,
4414 * (malloc.h): added CVS Id tag,
4415 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4417 * added libc directory. The current version of LibC contains string
4418 functions, ctype functions and macros and some functions of the
4419 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4420 be extensively tested in the future. Standard disclaimer here.
4421 Library is not automatically build yet. But one can build it by
4422 invoking 'make' inside the libc directory.
4423 * added ADC library under libio. Preliminary version yet.
4425 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4432 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4433 * (pic16_storeForReturn): optimized return of 0,
4434 * (genCmp): experimental code for new genCmp which uses PIC18's
4435 special compare&skip instructions. Initial tests fail some times
4436 with variables grater than 1 byte in size, so new code is disabled,
4437 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4439 * (genCast): began a fix to optimize the casting of a bit to another
4440 bit, now assigning a bitfield to another bitfield will fail, sorry,
4441 * src/pic16/main.c: disabled the use of lr-support feature,
4442 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4445 bits with offset (case PO_GPR_BIT),
4446 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4448 * (isBankInstruction): modified to return 0 for no banking instruction,
4449 and 1 for banking instruction,
4450 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4451 caused stop processing pCodes after a inline assembly block,
4452 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4453 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4454 registers when it shouldn't,
4455 * src/pic16/ralloc.c (allocReg): add preliminary support for
4456 supporting a limited set of temporary registers,
4458 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4460 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4461 genDataPointerSet): ensure assignments always copy in MSB to LSB
4463 (loadRegFromAop): recognize CLRH optimization,
4464 (genFunction): optimize RECEIVE iCodes in reentrant functions
4466 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4468 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4482 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4484 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7463 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7465 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7466 loaded with the linker search paths (-L arguments) and the libraries
7467 to be linked with the current source (-l arguments). Changes
7468 currently will affect only the pic16 port.
7469 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7470 include path the port specific paths and port specific libraries,
7471 * gplink command now contains the $3 argument,
7472 * src/pic16/device.h,
7473 * src/pic16/device.c,: structure PIC_device is made public and
7474 renamed to PIC16_device, the same for variable Pics which is renamed
7475 to Pics16. Updated all references to them.
7476 * src/pic16/glue.c (pic16glue): corrected bug with code
7477 initialization which bypassed the variable initializations block.

7487 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7489 Documenting changes from previous commits.
7490 * configure.in (version 1.56),
7491 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7492 when generating output files to configure the pic16 library,
7493 but now I've commented it out, since gputils aren't installed in the
7494 SF compile farm, so library won't compile
7496 * device/lib/Makefile.in (version 1.56): initially I've added in
7497 target 'all' the prerequestive 'model-pic16' so it compiled the
7498 pic16 library, but now I've commented it out for the same reasons
7500 * added targets 'model-pic16' and 'objects-pic16' to compile the
7502 * added target 'port-specific-objects-pic16' to handle the
7503 generated libraries and copy them into the build/ directory
7504 * added target 'clean-intermediate-pic16' to clean intermediate
7505 files into pic16 directory
7506 * in target 'installdirs' added line to create directory pic16 in
7507 the installation path
7509 * device/include/Makefile.in (version 1.11): in target 'install'
7510 added lines to copy all header files to installation path,
7511 * in target 'installdirs' added line create directory for pic16
7512 headers in the installation path
7514 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7527 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7528 option so that it actually works. Made it specific to the z80, since
7529 the gbz80 doesn't have these kinds of I/O ports.
7531 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7533 * device/include/z180.h,

7546 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7548 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7549 changed interrupt vector table generation to only emit declared vectors.
7550 * device/include/Makefile.in: added missing backslash
7551 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7553 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7555 Mainly changes to support compilation of the device libraries
7556 * src/pic16/device.c: stack is allocated via symbol and not
7557 via literal number. The symbol is placed in the corresponding
7558 position of the data ram
7559 * (pic16_dump_section): relocatable and absolute uninitialized
7560 data are now emitted in sorted order to reduce section naming,
7561 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7562 weren't marked as being in the access bank,
7564 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7566 Added portion of GNU PIC Library under the directory
7567 device/include/pic16 and device/lib/pic16. These files
7568 contain the declarations of SFRs for the PIC18Fxx2 devices.
7569 The directory is initialized via configure from toplevel.
7571 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7573 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7574 the spilllocations to be compared correctly
7576 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7578 * src/SDCCast.c (decorateType): fixed bug introduced today
7580 2004-01-12 Borut Razem <borut.razem AT siol.net>
7582 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7585 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7587 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7588 in simpler and even better code
7590 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7592 * src/SDCCicode.c (operandOperation): fixed bug #874819

7598 * doc/sdccman.lyx: Moved and added some sections, small changes
7599 all over. Telling LaTeX to be less strict with word spacing
7600 to better keep the right margin. Changed some notes about
7601 maintainance of the ports in section 3.2.1 - is it OK like this?
7603 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7605 SDCC source changes:
7606 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7639 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7640 UPPER for immediate operands,
7641 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7643 * src/pic16/peeph.def: all peepholes with movff are commented out,
7644 because there is a problem in the pcode peep optimizer,
7645 * src/pic16/ralloc.c: the register allocator can now reuse local
7646 function symbols for another function. This saves register usage.
7647 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7649 Added file src/pic16/NOTES with information about program writing on
7650 the current port version.

7659 * src/SDCCmain.c : fixed #872250: -l command line defined library
7660 files are scanned before standard library files
7662 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7679 gen51Code): more efficient parameter receive for --model-large
7682 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7685 * src/z80/main.c: added missed needLinkerScript flags (more than
7686 one port structure defined in these file)
7687 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
7690 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

7703 needLinkerScript flag
7705 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7706 * src/pic/glue.c: added variable udata_section_name to
7707 override default uninitialized data segment definition for
7708 devices only with SHAREBANK memory (reported from Erik Epetrich)
7709 * (pic14emitOverlay): modified to emit a commented overlay segment
7710 directive when no overlay data exist
7711 * (picglue): modified to emit uninitialized data segment
7712 according to udata_section_name

7717 arguments via -W option
7718 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7719 object file from '.rel' to '.o' in port->linker structure,
7720 changed size of fptr from 2 to 3 in port structure
7722 2004-01-07 Borut Razem <borut.razem AT siol.net>
7724 * support/scripts/sdcc.nsi: update PATH
7725 * support/scripts/sdcc.ico: craeted
7727 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7729 * device/include/Makefile.in: fix install
7730 * doc/Makefile: fix install
7732 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7734 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7736 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
7737 how the function variable allocation summary is displayed; also
7738 include information about variables allocated to the overlay
7741 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7743 * as/mcs51/lkmain.c: Help about -Y option

7755 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7757 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7758 (default behaviour).
7760 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7762 A python script to validate compiler diagnostic messages. It can be
7763 used to verify that sdcc complains about bad c source code and
7764 gives a good location of the error.
7765 * support/valdiag/Makefile,
7766 * support/valdiag/valdiag.py,
7767 * support/valdiag/tests/*
7769 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7771 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7772 * src/SDCCsymt.c (newEnumType),

7780 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7782 * src/common.h: added ifndef/define/endif macros
7783 around the header file.
7784 Bug reported from Jesus Calvino-Fraga
7786 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7788 * sdcc.spec: updated
7789 * device/include/Makefile.in: don't install CVS directories
7790 * device/lib/Makefile.in: added removal of CVS directories after install
7791 * doc/Makefile: fixed install, added local_icons
7792 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7793 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7794 * src/ds390/gen.c (genRightShift): fixed bug #870788
7795 * src/SDCCast.c (decorateType): fixed bug #870781
7797 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7799 PIC16 port related changes:
7800 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7801 added variable stackPos,
7803 * gen.c: genCall, assignResultValue: added support for
7804 pushing/retrieving function parameters to/from stack,
7805 genFunction,genEndFunction: setup stack frame for the
7807 genAddrOf: will be changed according to bug 863624
7809 * added files genutils.c and genutils.h which contain gen*
7810 debugged and optimised functions extracted from gen.c
7812 * glue.c: added variable 'externs' which holds extern symbols,
7813 pic16emitRegularMap: is modified to properly handle relocatable
7814 symbols under the new scheme,
7815 pic16createInterruptVect: is modified
7816 pic16printPublics: is modified to emit 'global' assembler directives,
7817 added pic16_printExterns to print extern symbols,
7818 pic16glue: initializes stack/frame pointer in the beginning of
7819 the assembly output. Temporary hack, will be corrected later,
7820 because gplink yet does not support stack and SDCC does not
7821 yet support a type of crt0.o object to create the final binary.
7823 * Removed many lines that contain 8051 legacy code.
7824 * The code is finally placed under a 'code' directive.
7825 * Added port specific options.
7827 * _process_pragma: simplified since now we do not need *special*
7828 include file to define SFR registers. But a separate header
7829 will be needed. This will be developed later.
7830 * _pic16_parseOptions: added, parses port specific options:
7831 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7832 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7833 --preplace-udata-with=
7835 * _pic16_setDefaultOptions: modified to initialize section names,
7836 but hack is temporarly out of order since it needs improvement.
7837 * _pic16_genAssemblerPreamble: configuration words are emitted by
7838 their address instead of their name. This part is incomplete and
7839 supports only the 18Fxx2 devices. Other devices will emit an error
7840 during assembly since they do not contain the same set of config
7842 * _pic16_genIVT: is modified,
7844 * pcode.c: added definitions for some hardware registers that are needed
7846 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7847 All PCI entries are updated. Now LFSR is supported.
7848 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7849 * added pic16_newpCodeOpLit2 to support instructions with
7850 two literal arguments
7851 * pic16_pCode2str: corrected code that emits assembler instructions
7852 with two literal operands and those that have an access bit modifier
7853 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7854 this fixes a bug which caused some labels to be lost, when an
7855 assembler directive was added, i.e. banksel,
7856 * pic16_FixRegisterBanking: improved logic that causes the insertion
7858 * InlineFunction: functions that are called once, are not any more
7859 inlined. This can be a port option in the future,
7861 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7863 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7864 hold the corresponding uninitialized symbols,
7865 * pic16_allocProcessorRegister: registers have explicit marked the
7867 * pic16_allocInternalRegister: registers are explicit marked as
7869 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7870 processing list, so bit registers were lost,
7873 * ralloc.h: added field 'accessBank' and original symbol operand
7874 in register definition,
7875 * removed the field isMapped from register definition,
7877 ** Several functions have been removed from various sources:
7878 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7879 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7880 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7881 pic16_assignRelocatableRegisters
7883 ** others have been introduced:
7884 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7885 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7887 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7889 * support/scripts/inc2h.pl: changed definition of BIT_AT
7890 to emit 'sbit at' instead of 'bit at'. This was a request.
7892 PIC16 port related preliminary changes:
7893 * gen.c: prefixed function popRegFromString with
7894 pic16_ and all references to it corrected
7895 * pcode.c: all pic16_pc_* hardware registers prefixed
7896 with underscore (_),
7897 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7898 * ralloc.c: newReg(): when register is REG_SFR then
7899 set address to rIdx,
7900 pic16_allocProcessorRegister(): marks register wasUsed=0
7901 pic16_writeUsedRegs(): added a call to assign processor
7902 registers via pic16_assignFixedRegisters
7904 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7906 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7907 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7908 variables in unused register banks. Also the SSEG is placed
7909 wherever there is enough space for it, and IDATA can be anywhere
7910 in internal RAM. For now compile using -Wl-Y[stack_size].
7911 The mem file is different for this option as well, since it
7912 makes no sense of talking about DSEG lenght.
7914 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7916 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7917 in certain cases, e.g. when ROM assignment, patch provided
7918 from Albert den Haan.
7920 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
7922 Many signedness and type propagation fixes:
7923 * src/SDCCicode.c: made geniCodeCast() static
7924 replaced SPEC_ by IS_ (cosmetic)
7925 (operandOperation): fixed div and mod operation
7926 (usualBinaryConversions): added support for promotion of char
7927 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)

8923 fetching of the pointer
8924 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8925 copied from genNearPointerSet()
8926 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8927 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8928 If they pop r0/r1 they must be called in the opposite order than aopOp().
8929 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8930 (resp. --stack-auto), prepared for --xstack

8939 these ports have their own __sdcc_external_start()
8941 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8943 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8944 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8945 type for bits was changed. It resulted in bit variables becoming
8946 global, which is not permitted in PIC 14 assembly output.
8948 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8950 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8963 A few small changes that speed up the peephole optimizer.
8967 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8969 Try to make the peephole optimizer smarter by maintaining
8970 an association between the assembly source code and the
8971 iCodes that originated them. Put this information to use
8972 with a new peephole rule condition "notVolatile" so that
8973 the rules can be aggressive yet still safe.
8978 * src/mcs51/peeph.def
8980 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8984 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8985 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8986 if the left or right operand symbols have the accuse flag set.
8988 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8990 Changed the type of the result of the ! (NOT) operator to char;
8991 previously it returned the same type as the source. This allows
8992 us to eliminate all the genFloatNot functions (all of its target
8993 implementations were very buggy) since !float can use the same
8996 * src/SDCCicode.c (ast2iCode): ! returns char

8998 * src/ds390/gen.c (genNot, genNotFloat),
8999 * src/z80/gen.c (genNot, genNotFloat),
9000 * src/pic/gen.c (genNot, genNotFloat),

9005 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9006 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9007 during interrupts. Ensure WSAVE is located at a shared bank address.
9008 2. Fixed page selection in some places
9009 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9010 the registers name strings.
9011 4. Fixed "signed / unsigned compare" compiler warnings.
9012 5. The PIC port manages its own allocation of the general purpose
9013 registers, but makes no attempt to reuse them. As a result when
9014 compiling it soon runs out of general purpose registers. Some
9015 additional code was added to the files pcode.c and device.c to walk
9016 through the function call tree and rename the registers so that they
9026 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9033 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9035 Made bitfield a distinct type from bit so that bitfields
9036 convert as per ANSI C and bits retain their traditional
9037 boolean style behaviour. Implemented bitfield support in
9045 * src/ds390/gen.c: bit v bitfield split
9046 * src/z80/gen.c: New support for bitfields
9047 * support/regression/tests/bitfields.c: reenabled z80,
9050 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9052 Rules 246.x, 247.x relate to bitfields, the others speed up
9053 access to xdata mapped I/O devices.
9055 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9057 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9059 Cleaned up genPackBits and genUnpackBits and added two helper
9060 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9061 for literal assignments in genPackBits (thanks to Frieder for
9067 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9069 Fixed bug #748310 (pointer to function type mishandled when the
9070 function name is omitted). Also fixed a SIGSEGV when a function
9071 attribute (reentrant, etc) is used on a non-function or on a
9072 function but misplaced before the parameter list.
9074 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9076 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9099 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9101 Made the constant following the "interrupt" keyword optional. If
9102 omitted, the function will not automatically be given an entry
9103 in the interrupt vector table (similar to #pragma NOIV, but
9104 less syntacticly kludgy). The interrupt number is also now
9105 range checked. Also fixed a bug in the high order bit example

9121 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9123 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9124 be re-activated by defining REDUCE_LITERALS)
9125 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9126 unsigned, but are signed by default
9127 * src/SDCCval.c (constVal): rearranged
9128 * src/SDCCval.c (valMod): preliminary fix
9129 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9581 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9582 the regression tests I'm not brave enough to enable 245.b, 245.c
9583 * doc/sdccman.lyx: added latex preamble for hyperref package.
9584 Using pdflatex this will give you a hyperlinked pdf file with
9585 bookmarks. (prepend '%' before /usepackage if this breaks something)

9601 Applied patch from bug 737905 (renamed yylineo to mylineno):
9608 * src/pic16/pcode.c: Cleaned warnings
9609 * src/pic16/pcodeflow.c: Cleaned warnings
9610 * src/pic16/pcoderegs.c: Cleaned warnings

9623 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9625 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9626 it can be defined with CFLAGS when running configure
9627 * src/SDCCmain.c: fixed compiling + linking with object files
9629 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9632 added --disable-pic16-port
9633 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9634 * src/SDCCmain.c: linkOptions is changed to set *,
9635 added if/endif conditional macros to remove options help
9636 messages from optionsTable when a port is not configured, added
9637 support for the PIc16 port in the ports table, when executing
9638 the compiler with no port specified on command line, a default
9639 port is selected with the new macro DEFAULT_PORT which is
9640 defined in port.h, in setDefaultOptions() linkOptions is removed
9641 from initialization assignment, since now it is a set,
9642 parseCmdLine uses setParseWithComma for linkOptions, in
9643 linkEdit() linkOptions are accessed with new function indexSet()
9644 which returns the i'th item of a set variable. See SDCCset.c, in
9645 linkEdit() when calling buildCmdLine(), added linkOptions as
9646 last argument. Now users can pass arguments to gplink via the
9647 -Wl option, main() uses pic16glue() to glue up pic16 programs
9648 * src/SDCCpeeph.c: various changes to support pic16

9659 * src/pic16/glue.c: commented out some error producing lines
9660 * src/pic16/main.c: __config directives are commented out to stop
9661 gpasm complaining and test the linkage with gplink, _linkCmd and
9662 _asmCmd changed to be more gplink and gpasm friendly
9663 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9664 produced an error when parsed, peep rule 12 is added to utilize
9665 movff, but it is commented out since the pCode does not support
9666 yet a command with 2 address arguments
9668 2003-05-18 <johan AT balder>
9670 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9671 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9695 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9697 2003-05-11 Borut Razem <borut.razem AT siol.net>
9699 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9700 the path of bin directory, so that PATH is the only env. variable, which has to be set
9701 in case of standard installation.
9702 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10734 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10735 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10736 following files to include the previous two files: aslink.dsp,
10737 Makefile.aslink, Makefile.bcc, and Makefile.in.
10739 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10740 .adb instead of .cdb
10742 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10744 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10745 value from option --iram-size.
10747 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10749 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10752 2002-09-18 <wiml AT hhhh.org>
10754 * SDCClrange.h: exposed setFromRange() and setToRange()
10755 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10756 packRegsForAccUse() (bug 542397)
10757 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10758 multiple times and emitting the fetch operations more than once
10759 added aopGetUsesAcc() function to allow binary operators to
10760 fetch their operands in the correct order; made genMinus() emit
10761 compact code for X = LITERAL - Y
10763 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10764 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

10771 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10772 Changes to aslink (All the changes are marked with 'JCF'):
10774 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10777 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10778 area BSEG. Also moves, if possible, the DATA area down into the internal
10779 ram so more space is available.
10781 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10784 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10785 not bytes. Function summary() which creates a memory usage summary
10786 file with extension .mem. Reports of overlaping stack and small stack
10787 size. If the space for the stack is less than 16 bytes aslink trows a
10790 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10791 the 8051. Option 'y' for memory summary output file.
10793 Changes to sdcc (All the changes are marked with 'JCF'):
10795 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10797 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10798 overlaying area for it (uses RegBankUsed[4]).
10800 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10801 bank zero as used by default. By default aslink locates the stack
10802 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10803 the creation of the .mem file. Delegates the allocation of data area
10804 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10805 the begining of the stack area to aslink.
10807 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10808 glue() in SDCCglue.c creates an area for it.

10811 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10812 sdcc/src/pic/glue.c:
10813 introduced atexit() handler for teporay files removal in case of
10814 errors, assertions, ...
10816 2002-08-29 Borut Razem <borut.razem AT siol.net>
10817 * sdcc/support/cpp2/auto-host_vc_in.h:
10818 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10819 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10820 Maybe there is a similar problem with BORLANDC? It should be checked!
10822 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10823 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10824 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10825 was not executed, and the compiler (cl) launched a warning:
10826 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10828 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10829 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10831 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10832 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10834 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10835 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10836 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10837 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10838 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10839 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10840 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10841 - added Release configuration in VS projects
10842 - review of compiler an linker options
10843 - VC .exe files are generated in bin_vc directory, not to interfere
10844 with binaries generated from other projects (cygwin, mingw, bcc ...)
10846 * sdcc/src/yacc.dsp: added
10848 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10849 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10850 and insert the version number definitions from .version
10852 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10854 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10855 added - genarate auto-host.h using auto-host_vc_in.h as template
10858 removed from CVS, generated automatically
10860 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10861 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10863 2002-08-11 Borut Razem <borut.razem AT siol.net>
10864 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10866 2002-08-10 Borut Razem <borut.razem AT siol.net>
10867 * src/SDCCmain.c (main):
10868 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10869 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10870 The consequence was that some temporary files were not removed.
10873 unification of code in functions tempfilename() and tempfile():
10874 function tempnam() is defined in Visual Studio 6.0 and .NET
10876 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10878 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10879 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10880 - removed compiler command line option /WX: Treats all warnings as errors
10881 - update a list of source files, included into the project
10883 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10884 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10885 changed project type to Generic Project so that can be correcly converted to VS.NET project
10887 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10889 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10891 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10893 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10894 added return 0 statements after assert() to make compiler happy
10896 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10897 added newline in the def file to keep MSC compiler satisfied
10899 * sdcc/src/z80/gen.c:
10900 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10901 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10902 - solved MSC error in function aopDump()
10904 * sdcc_vc.h: define PREFIX as "\\sdcc"
10906 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10907 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10910 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10911 - Rewrote the register banking algorithm.
10912 - Added pCode live-range analysis to registers (for now, only non-used and
10913 singly-used registers optimized away)
10915 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

10944 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10946 2002-03-28 Johan Knol <johan AT balder>
10948 * src/SDCCval.c: fixed bug #532436
10950 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10955 Added -p option. Allows port dependent processor to be specified.
10958 Initialized the new field char *Processor field to NULL in all ports
10961 Compiler generated registers for interrupt context saving
10962 were not getting allocated.
10964 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

11079 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11081 * sdcc/src/SDCCloop.c:
11082 Previous fix was not good. basic blocks that have "break" or "return" are
11083 not really partof a loop , but live ranges used in these blocks should
11084 be live thru the entire loop, so set partOfLoop but don't add them to
11087 2002-02-21 <johan AT FRIJA>
11089 * src/SDCCcse.c: fixed bug #514308
11091 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
