2079 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2081 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2082 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2084 One basic decision: e.g. src/clean.mk includes further files. In order
2085 to make this work there are two solutions:
2086 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2087 run configure on them. This way they can use
2088 'include $(srcdir)/port-clean.mk'
2089 - always include clean.mk by the Makefile at the same level. To avoid
2090 that `make clean` tries to include and build Makefile.dep the
2091 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2092 implemented, because now even `make uninstall` doesn't create
2093 Makefile.in. clean.mk could be eliminated by pasting it in
2096 * debugger/mcs51/Makefile.in: build own objects from library sources
2097 (SLIB, SDCC) in current directory
2099 * configure, configure.in: renamed --disable-device-lib-build in
2100 --disable-device-lib; added --enable-doc, the required tools are
2101 searched by configure; added result message; the toolchain for the
2102 belonging ports are now only built, if the port is enabled.
2104 * support/regression/*: all output is written in directory gen, because
2105 the fwk and ports directories don't livet in the build tree using vpath
2107 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2108 --disable-device-lib, added --enable-doc, added section VPATH
2110 * sim/ucsim/configure.in,
2111 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2112 z80 are enabled by default
2114 2006-04-24 Raphael Neider <rneider AT web.de>
2116 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2117 to config word, "pic14_"-prefixed some extern functions
2118 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2119 config word has been found
2120 * src/pic/device.h: added prototypes
2121 * src/pic/pcode.c: added "pic14_"-prefix where needed
2122 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2124 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2127 (pic14createInterruptVect): moved generating __config directives away

2138 fixes #1469504 and #1474602,
2139 (pCodeRegOptimizeRegUsage): fixed typo in comment
2141 2006-04-24 Borut Razem <borut.razem AT siol.net>
2143 * device/examples/main8051.c: deleted - it was removed from CVS
2144 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2145 after the transition to Subversion
2146 * src/SDCCalloc.h: deleted - it was removed from CVS
2147 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2385 implemented patch 1120823 Thanks to Willy De la Court (normal
2386 interrupts need an interrupt number now if they are made critical),
2387 and enabled nesting of critical functions though not for gbz80
2388 (genCritical, genEndCritical): added functions
2389 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2390 * src/z80/mappings.i: added "ei" to all mappings

2402 the left operand is shorter than the result (c* = lit-c* + int),
2404 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2407 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2409 * src/.version: increased version number to 2.5.5
2410 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2411 linking is done manually in pic16 port's _linkEdit,
2412 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2413 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2414 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2415 allocate asmop as AOP_ACC,
2416 (aopForRemat): added parameter 'bool result' in function declaration,
2417 (pic16_aopGet): return AOP_ACC when accessing WREG,
2418 (pic16_popGetTempReg): minor modification,

2429 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2430 call to allocReg, not by manually allocating a new one,
2431 (pic16_assignRegisters): now before going through the register
2432 allocating functions mark all registers as free. This eliminates some
2433 side effects resulting from peephole parser done earlier in the backbone
2435 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2493 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2494 which dumps before the function entry point a data byte which represents
2495 the number of the local variables used by the specified function, added
2496 'xinst' for initial support for Extended Instruction Support,
2497 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2498 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2499 port->fun_prefix anymore (may change later),
2500 (genFunction, genEndFunction): do not store/restore local registers for
2501 _main (this should take care the --main-return command line option in
2503 (genOr): removed some legacy pic-port instructions,
2504 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2505 performing operations with SFR's causes data to be written more than
2506 once to each SFR. Perhaps SFRs should be handled in special cases...
2507 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2509 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2510 into account for stack starting position,

2512 --extended or -y for Extended Instruction Support,
2513 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2514 (deassignLRs): *** perhaps the most important change, old 'for' code
2515 (commented out for reference), didn't account for some registers which
2516 were left marked 'not free' after a pointer operation. The change
2517 reduces register usage a lot in some cases
2519 2006-03-04 Borut Razem <borut.razem AT siol.net>

4792 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4793 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4794 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4795 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4796 always available in leading double underscore form. The C99 support is
4797 mostly missing, but it's a start.
4798 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4799 reserved identifier "__data".
4801 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4877 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4879 * device/lib/printf_large.c: removed inline assembly for portability and
4880 readability. Use printf_fast if speed or size are more important.
4881 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4882 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4884 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4886 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4887 prevent compiler warning
4889 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4891 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4892 moved to level 0 and declared as static. Also they are explicit
4893 placed in access bank. This was necessery because some times they
4894 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4895 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4896 optimizations. Currently only compare to unsigned char is implemented,
4897 * src/pic16/gen.c: added fReturnIdx array,
4898 * (struct resolvedIfx) is moved to gen.h and made public,
4899 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4900 * (aopForSym): added an optimization to directly store in stack of
4901 the operand of a SEND iCode,
4902 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4903 but as registers instead (AOP_REG) using the fReturnIdx array,
4904 * (pic16_freeAsmop): remove the freed register from the
4905 _G.sregsAlloc field,
4906 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4907 a compare of 'WREG',
4908 * (pic16_popGetTempRegCond): changed function prototype, now
4909 function takes also a bitVector argument v which holds the current
4910 set of registers that are allocated for stack access by aopForSym,
4911 registers allocated in aopForSym for accessing stack symbols are not
4912 any more part of the functions usedRegs field,
4913 * (genCall): some times aopOp is called for a stack variable to be
4914 send, aopForSym might perform the push, if this is true make sure
4915 that genCall doesn't push the variable twice by testing _G.resDirect,
4916 * (genFunction): changed testing for unspecified interrupt number
4917 from 256 to INTNO_UNSPEC,
4918 * modified selection scheme of frame pointer generation. Previously
4919 if function did use local registers a frame pointer was generated,
4920 now a frame pointer is generated only if function has arguments
4921 (that need PLUSW2 register access), or has stack arguments, or the
4922 compiler is not instructed to omit the frame pointer,
4923 * (genEndFunction): before restoring local registers that were saved
4924 in the function preamble, also restore the registers that *might*
4925 have been allocated for stack access,
4926 * (genRet): removed some old comments,
4927 * (genCmp, the active (RN's) version): added a call to the
4928 pic16_genCmp_special function to perform the compare with a more
4929 robust and optimized way,
4930 * (genInline): a feature has been added in inline code generation,
4931 which allows a wildcard variable substitution when writing inline
4932 assembly. Code is incomplete and experimental therefore undocumented,
4933 * (genCast): changed order of aopOp for result and right to allow
4934 aopForSym to directly load the result if possible,
4935 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4936 perform an optimized compare on some selected special occasions,
4937 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4938 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4939 generate an IVT any more,
4940 * src/pic16/main.c (pic16_optionsTable): added command line option
4942 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4943 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4945 * src/pic16/NOTES: Raphael Neider added in list of active developers
4946 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4947 jumptable_end to prevent bug #,
4948 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4949 inCond and outCond fields,
4950 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4951 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4952 turn off register spilling,
4953 * (packRegsForOneUse): synced with other ports' versions although it
4954 is not used currently,
4955 * (pic16_packRegisters): added an optimization while reading
4956 structure bitfields, some registers may be saved (malloc code is
4957 decreased by 80 bytes)
4959 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4961 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4962 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4963 this can be optimized more?
4965 2005-03-10 Raphael Neider <rneider AT web.de>
4967 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4968 genNearPointerGet): (hopefully) fixed access to bitfields via
4969 pointers (p->bitN = x; and x = p->bitN; failed)
4971 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5584 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
5586 (setFromConditionArgs): friendly operand parser for peephole rules,
5587 (operandBaseName, operandsNotRelated): new peephole condition
5588 "operandsNotRelated" -- similar to "operandsNotSame", but takes
5589 architecture specific register naming into account, handles n-way
5590 comparisons, and supports quoted literals
5591 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

5601 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5603 Adding support for replacing ljmps with sjmps in jumptables
5604 generated for switch statements. For now you need to set the
5605 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5606 Now 4 algorithms for mcs51 jumptable generation are used:
5607 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5608 addresses loaded pc-relative for up to 112 cases and stack-pushing
5609 target addresses loaded with offset from dptr for up to 256 cases.
5611 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5612 * src/mcs51/main.c: adapted constants for switch table generation
5613 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

5635 Large cummulative patch for pic16 port.
5636 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5637 to call when a stack overflow occurs,
5638 * (malloc.h): added CVS Id tag,
5639 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5641 * added libc directory. The current version of LibC contains string
5642 functions, ctype functions and macros and some functions of the
5643 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5644 be extensively tested in the future. Standard disclaimer here.
5645 Library is not automatically build yet. But one can build it by
5646 invoking 'make' inside the libc directory.
5647 * added ADC library under libio. Preliminary version yet.
5649 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5656 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5657 * (pic16_storeForReturn): optimized return of 0,
5658 * (genCmp): experimental code for new genCmp which uses PIC18's
5659 special compare&skip instructions. Initial tests fail some times
5660 with variables grater than 1 byte in size, so new code is disabled,
5661 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5663 * (genCast): began a fix to optimize the casting of a bit to another
5664 bit, now assigning a bitfield to another bitfield will fail, sorry,
5665 * src/pic16/main.c: disabled the use of lr-support feature,
5666 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5667 * added some function prototypes, added function _debugf prototype,
5668 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5669 bits with offset (case PO_GPR_BIT),
5670 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5672 * (isBankInstruction): modified to return 0 for no banking instruction,
5673 and 1 for banking instruction,
5674 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5675 caused stop processing pCodes after a inline assembly block,
5676 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5677 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5678 registers when it shouldn't,
5679 * src/pic16/ralloc.c (allocReg): add preliminary support for
5680 supporting a limited set of temporary registers,
5682 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5684 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5685 genDataPointerSet): ensure assignments always copy in MSB to LSB
5687 (loadRegFromAop): recognize CLRH optimization,
5688 (genFunction): optimize RECEIVE iCodes in reentrant functions
5690 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5692 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5693 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5695 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
5696 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
5697 contiguous with data

5701 * device/lib/_gptrget.c (_gptrget),
5702 * device/lib/_gptrgetc.c (_gptrgetc),
5703 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5704 instead of sjmp to ret
5705 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5706 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5708 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8678 * src/SDCCval.c (cheapestVal): added missing checks
8679 * src/SDCCicode.c (usualBinaryConversions): fixed condition
8680 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
8682 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
8684 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
8687 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8689 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8690 loaded with the linker search paths (-L arguments) and the libraries
8691 to be linked with the current source (-l arguments). Changes
8692 currently will affect only the pic16 port.
8693 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8694 include path the port specific paths and port specific libraries,
8695 * gplink command now contains the $3 argument,
8696 * src/pic16/device.h,
8697 * src/pic16/device.c,: structure PIC_device is made public and
8698 renamed to PIC16_device, the same for variable Pics which is renamed
8699 to Pics16. Updated all references to them.
8700 * src/pic16/glue.c (pic16glue): corrected bug with code
8701 initialization which bypassed the variable initializations block.
8703 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8704 COMPILE_FLAGS and added the --nostdinc option
8706 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8708 * device/include/mc68hc908jb8.h: Register defs for another member
8709 of the hc08 family. Contributed by Bjorn Bringert - thanks!
8711 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8713 Documenting changes from previous commits.
8714 * configure.in (version 1.56),
8715 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8716 when generating output files to configure the pic16 library,
8717 but now I've commented it out, since gputils aren't installed in the
8718 SF compile farm, so library won't compile
8720 * device/lib/Makefile.in (version 1.56): initially I've added in
8721 target 'all' the prerequestive 'model-pic16' so it compiled the
8722 pic16 library, but now I've commented it out for the same reasons
8724 * added targets 'model-pic16' and 'objects-pic16' to compile the
8726 * added target 'port-specific-objects-pic16' to handle the
8727 generated libraries and copy them into the build/ directory
8728 * added target 'clean-intermediate-pic16' to clean intermediate
8729 files into pic16 directory
8730 * in target 'installdirs' added line to create directory pic16 in
8731 the installation path
8733 * device/include/Makefile.in (version 1.11): in target 'install'
8734 added lines to copy all header files to installation path,
8735 * in target 'installdirs' added line create directory for pic16
8736 headers in the installation path
8738 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

8749 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8751 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8752 option so that it actually works. Made it specific to the z80, since
8753 the gbz80 doesn't have these kinds of I/O ports.
8755 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8757 * device/include/z180.h,

8763 * device/lib/_strcmp.c,
8764 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
8765 * src/z80/main.c (_process_pragma): add support for pragmas bank and
8766 portmode; added deprecation warning for bank= and protmode= forms.
8767 Also, guard against buffer overflow.
8768 * src/z80/gen.c (aopGet): generate better code for sfr banked read
8770 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8772 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8773 changed interrupt vector table generation to only emit declared vectors.
8774 * device/include/Makefile.in: added missing backslash
8775 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
8777 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8779 Mainly changes to support compilation of the device libraries
8780 * src/pic16/device.c: stack is allocated via symbol and not
8781 via literal number. The symbol is placed in the corresponding
8782 position of the data ram
8783 * (pic16_dump_section): relocatable and absolute uninitialized
8784 data are now emitted in sorted order to reduce section naming,
8785 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8786 weren't marked as being in the access bank,
8788 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8790 Added portion of GNU PIC Library under the directory
8791 device/include/pic16 and device/lib/pic16. These files
8792 contain the declarations of SFRs for the PIC18Fxx2 devices.
8793 The directory is initialized via configure from toplevel.
8795 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8797 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8798 the spilllocations to be compared correctly
8800 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8802 * src/SDCCast.c (decorateType): fixed bug introduced today
8804 2004-01-12 Borut Razem <borut.razem AT siol.net>
8806 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8809 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8811 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8812 in simpler and even better code
8814 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8816 * src/SDCCicode.c (operandOperation): fixed bug #874819

8820 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8822 * doc/sdccman.lyx: Moved and added some sections, small changes
8823 all over. Telling LaTeX to be less strict with word spacing
8824 to better keep the right margin. Changed some notes about
8825 maintainance of the ports in section 3.2.1 - is it OK like this?
8827 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8829 SDCC source changes:
8830 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8864 UPPER for immediate operands,
8865 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8867 * src/pic16/peeph.def: all peepholes with movff are commented out,
8868 because there is a problem in the pcode peep optimizer,
8869 * src/pic16/ralloc.c: the register allocator can now reuse local

8871 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8873 Added file src/pic16/NOTES with information about program writing on
8874 the current port version.

8927 needLinkerScript flag
8929 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8930 * src/pic/glue.c: added variable udata_section_name to
8931 override default uninitialized data segment definition for
8932 devices only with SHAREBANK memory (reported from Erik Epetrich)
8933 * (pic14emitOverlay): modified to emit a commented overlay segment
8934 directive when no overlay data exist
8935 * (picglue): modified to emit uninitialized data segment
8936 according to udata_section_name

8946 2004-01-07 Borut Razem <borut.razem AT siol.net>
8948 * support/scripts/sdcc.nsi: update PATH
8949 * support/scripts/sdcc.ico: craeted
8951 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

8962 include information about variables allocated to the overlay
8965 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8967 * as/mcs51/lkmain.c: Help about -Y option

8979 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8981 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8982 (default behaviour).
8984 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8986 A python script to validate compiler diagnostic messages. It can be
8987 used to verify that sdcc complains about bad c source code and
8988 gives a good location of the error.
8989 * support/valdiag/Makefile,
8990 * support/valdiag/valdiag.py,
8991 * support/valdiag/tests/*
8993 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8995 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9004 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9006 * src/common.h: added ifndef/define/endif macros
9007 around the header file.
9008 Bug reported from Jesus Calvino-Fraga
9010 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9012 * sdcc.spec: updated
9013 * device/include/Makefile.in: don't install CVS directories
9014 * device/lib/Makefile.in: added removal of CVS directories after install
9015 * doc/Makefile: fixed install, added local_icons
9016 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9017 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9018 * src/ds390/gen.c (genRightShift): fixed bug #870788
9019 * src/SDCCast.c (decorateType): fixed bug #870781
9021 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9023 PIC16 port related changes:
9024 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9025 added variable stackPos,
9027 * gen.c: genCall, assignResultValue: added support for
9028 pushing/retrieving function parameters to/from stack,
9029 genFunction,genEndFunction: setup stack frame for the
9031 genAddrOf: will be changed according to bug 863624
9033 * added files genutils.c and genutils.h which contain gen*
9034 debugged and optimised functions extracted from gen.c
9036 * glue.c: added variable 'externs' which holds extern symbols,
9037 pic16emitRegularMap: is modified to properly handle relocatable
9038 symbols under the new scheme,
9039 pic16createInterruptVect: is modified
9040 pic16printPublics: is modified to emit 'global' assembler directives,
9041 added pic16_printExterns to print extern symbols,
9042 pic16glue: initializes stack/frame pointer in the beginning of
9043 the assembly output. Temporary hack, will be corrected later,
9044 because gplink yet does not support stack and SDCC does not
9045 yet support a type of crt0.o object to create the final binary.
9047 * Removed many lines that contain 8051 legacy code.
9048 * The code is finally placed under a 'code' directive.
9049 * Added port specific options.
9051 * _process_pragma: simplified since now we do not need *special*
9052 include file to define SFR registers. But a separate header
9053 will be needed. This will be developed later.
9054 * _pic16_parseOptions: added, parses port specific options:
9055 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9056 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9057 --preplace-udata-with=
9059 * _pic16_setDefaultOptions: modified to initialize section names,
9060 but hack is temporarly out of order since it needs improvement.
9061 * _pic16_genAssemblerPreamble: configuration words are emitted by
9062 their address instead of their name. This part is incomplete and
9063 supports only the 18Fxx2 devices. Other devices will emit an error
9064 during assembly since they do not contain the same set of config
9066 * _pic16_genIVT: is modified,
9068 * pcode.c: added definitions for some hardware registers that are needed
9070 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9071 All PCI entries are updated. Now LFSR is supported.
9072 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9073 * added pic16_newpCodeOpLit2 to support instructions with
9074 two literal arguments
9075 * pic16_pCode2str: corrected code that emits assembler instructions
9076 with two literal operands and those that have an access bit modifier
9077 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9078 this fixes a bug which caused some labels to be lost, when an
9079 assembler directive was added, i.e. banksel,
9080 * pic16_FixRegisterBanking: improved logic that causes the insertion
9082 * InlineFunction: functions that are called once, are not any more
9083 inlined. This can be a port option in the future,
9085 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9087 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9088 hold the corresponding uninitialized symbols,
9089 * pic16_allocProcessorRegister: registers have explicit marked the
9091 * pic16_allocInternalRegister: registers are explicit marked as
9093 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9094 processing list, so bit registers were lost,
9097 * ralloc.h: added field 'accessBank' and original symbol operand
9098 in register definition,
9099 * removed the field isMapped from register definition,
9101 ** Several functions have been removed from various sources:
9102 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9103 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9104 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9105 pic16_assignRelocatableRegisters
9107 ** others have been introduced:
9108 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9109 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9111 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9113 * support/scripts/inc2h.pl: changed definition of BIT_AT
9114 to emit 'sbit at' instead of 'bit at'. This was a request.
9116 PIC16 port related preliminary changes:
9117 * gen.c: prefixed function popRegFromString with
9118 pic16_ and all references to it corrected
9119 * pcode.c: all pic16_pc_* hardware registers prefixed
9120 with underscore (_),
9121 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9122 * ralloc.c: newReg(): when register is REG_SFR then
9123 set address to rIdx,
9124 pic16_allocProcessorRegister(): marks register wasUsed=0
9125 pic16_writeUsedRegs(): added a call to assign processor
9126 registers via pic16_assignFixedRegisters
9128 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9130 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9131 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9132 variables in unused register banks. Also the SSEG is placed
9133 wherever there is enough space for it, and IDATA can be anywhere
9134 in internal RAM. For now compile using -Wl-Y[stack_size].
9135 The mem file is different for this option as well, since it
9136 makes no sense of talking about DSEG lenght.
9138 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9140 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9141 in certain cases, e.g. when ROM assignment, patch provided
9142 from Albert den Haan.
9144 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10153 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10154 (resp. --stack-auto), prepared for --xstack
10156 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10158 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10160 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10162 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10163 these ports have their own __sdcc_external_start()
10165 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10167 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10168 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10169 type for bits was changed. It resulted in bit variables becoming
10170 global, which is not permitted in PIC 14 assembly output.
10172 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10174 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10176 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10178 Z80 and MCS51 linkers complaint if a public symbol is defined
10179 in more than one library module:

10185 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10187 A few small changes that speed up the peephole optimizer.
10191 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10193 Try to make the peephole optimizer smarter by maintaining
10194 an association between the assembly source code and the
10195 iCodes that originated them. Put this information to use
10196 with a new peephole rule condition "notVolatile" so that
10197 the rules can be aggressive yet still safe.
10202 * src/mcs51/peeph.def
10204 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10208 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10209 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10210 if the left or right operand symbols have the accuse flag set.
10212 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10214 Changed the type of the result of the ! (NOT) operator to char;
10215 previously it returned the same type as the source. This allows
10216 us to eliminate all the genFloatNot functions (all of its target
10217 implementations were very buggy) since !float can use the same
10220 * src/SDCCicode.c (ast2iCode): ! returns char

10229 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10230 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10231 during interrupts. Ensure WSAVE is located at a shared bank address.
10232 2. Fixed page selection in some places
10233 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10234 the registers name strings.
10235 4. Fixed "signed / unsigned compare" compiler warnings.
10236 5. The PIC port manages its own allocation of the general purpose
10237 registers, but makes no attempt to reuse them. As a result when
10238 compiling it soon runs out of general purpose registers. Some
10239 additional code was added to the files pcode.c and device.c to walk
10240 through the function call tree and rename the registers so that they
10250 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10251 genPlus() & genMinus() when the result is the same as left or right
10253 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10257 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10259 Made bitfield a distinct type from bit so that bitfields
10260 convert as per ANSI C and bits retain their traditional
10261 boolean style behaviour. Implemented bitfield support in
10269 * src/ds390/gen.c: bit v bitfield split
10270 * src/z80/gen.c: New support for bitfields
10271 * support/regression/tests/bitfields.c: reenabled z80,
10274 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10276 Rules 246.x, 247.x relate to bitfields, the others speed up
10277 access to xdata mapped I/O devices.
10279 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10281 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10283 Cleaned up genPackBits and genUnpackBits and added two helper
10284 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10285 for literal assignments in genPackBits (thanks to Frieder for
10291 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10293 Fixed bug #748310 (pointer to function type mishandled when the
10294 function name is omitted). Also fixed a SIGSEGV when a function
10295 attribute (reentrant, etc) is used on a non-function or on a
10296 function but misplaced before the parameter list.
10298 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10300 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10301 * support/Util/SDCCerr.h,

10304 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10306 Fixed bug #787649 by anonymous
10307 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10308 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10310 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10323 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10325 Made the constant following the "interrupt" keyword optional. If
10326 omitted, the function will not automatically be given an entry
10327 in the interrupt vector table (similar to #pragma NOIV, but
10328 less syntacticly kludgy). The interrupt number is also now
10329 range checked. Also fixed a bug in the high order bit example
10336 * support/Util/SDCCerr.c
10337 * support/Util/SDCCerr.h

10345 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10347 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10348 be re-activated by defining REDUCE_LITERALS)
10349 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10350 unsigned, but are signed by default
10351 * src/SDCCval.c (constVal): rearranged
10352 * src/SDCCval.c (valMod): preliminary fix

10805 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10806 the regression tests I'm not brave enough to enable 245.b, 245.c
10807 * doc/sdccman.lyx: added latex preamble for hyperref package.
10808 Using pdflatex this will give you a hyperlinked pdf file with
10809 bookmarks. (prepend '%' before /usepackage if this breaks something)

10847 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10849 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10850 it can be defined with CFLAGS when running configure
10851 * src/SDCCmain.c: fixed compiling + linking with object files
10853 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10858 * src/SDCCmain.c: linkOptions is changed to set *,
10859 added if/endif conditional macros to remove options help
10860 messages from optionsTable when a port is not configured, added
10861 support for the PIc16 port in the ports table, when executing
10862 the compiler with no port specified on command line, a default
10863 port is selected with the new macro DEFAULT_PORT which is
10864 defined in port.h, in setDefaultOptions() linkOptions is removed
10865 from initialization assignment, since now it is a set,
10866 parseCmdLine uses setParseWithComma for linkOptions, in
10867 linkEdit() linkOptions are accessed with new function indexSet()
10868 which returns the i'th item of a set variable. See SDCCset.c, in
10869 linkEdit() when calling buildCmdLine(), added linkOptions as
10870 last argument. Now users can pass arguments to gplink via the
10871 -Wl option, main() uses pic16glue() to glue up pic16 programs
10872 * src/SDCCpeeph.c: various changes to support pic16
10873 * src/SDCCset.c: added function void *indexSet(set *, int) to
10874 return the i'th item of the set

10883 * src/pic16/glue.c: commented out some error producing lines
10884 * src/pic16/main.c: __config directives are commented out to stop
10885 gpasm complaining and test the linkage with gplink, _linkCmd and
10886 _asmCmd changed to be more gplink and gpasm friendly
10887 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10888 produced an error when parsed, peep rule 12 is added to utilize
10889 movff, but it is commented out since the pCode does not support
10890 yet a command with 2 address arguments
10892 2003-05-18 <johan AT balder>
10894 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10921 2003-05-11 Borut Razem <borut.razem AT siol.net>
10923 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

11987 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11988 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11989 sprintf() in line 1267.
11991 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11992 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11995 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11996 Changes to aslink (All the changes are marked with 'JCF'):
11998 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12001 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12002 area BSEG. Also moves, if possible, the DATA area down into the internal
12003 ram so more space is available.
12005 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12008 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12009 not bytes. Function summary() which creates a memory usage summary
12010 file with extension .mem. Reports of overlaping stack and small stack
12011 size. If the space for the stack is less than 16 bytes aslink trows a
12014 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12015 the 8051. Option 'y' for memory summary output file.
12017 Changes to sdcc (All the changes are marked with 'JCF'):
12019 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12021 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12022 overlaying area for it (uses RegBankUsed[4]).
12024 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12025 bank zero as used by default. By default aslink locates the stack
12026 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12027 the creation of the .mem file. Delegates the allocation of data area
12028 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12029 the begining of the stack area to aslink.
12031 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12032 glue() in SDCCglue.c creates an area for it.
12034 2002-09-03 Borut Razem <borut.razem AT siol.net>
12035 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12036 sdcc/src/pic/glue.c:
12037 introduced atexit() handler for teporay files removal in case of
12038 errors, assertions, ...
12040 2002-08-29 Borut Razem <borut.razem AT siol.net>
12041 * sdcc/support/cpp2/auto-host_vc_in.h:
12042 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12043 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12044 Maybe there is a similar problem with BORLANDC? It should be checked!
12046 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12047 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12048 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12049 was not executed, and the compiler (cl) launched a warning:
12050 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12052 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12053 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12055 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12056 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12058 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12059 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12060 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12061 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12062 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12063 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12064 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12065 - added Release configuration in VS projects
12066 - review of compiler an linker options
12067 - VC .exe files are generated in bin_vc directory, not to interfere
12068 with binaries generated from other projects (cygwin, mingw, bcc ...)
12070 * sdcc/src/yacc.dsp: added
12072 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12073 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12074 and insert the version number definitions from .version
12076 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12078 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12079 added - genarate auto-host.h using auto-host_vc_in.h as template
12082 removed from CVS, generated automatically
12084 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12085 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12087 2002-08-11 Borut Razem <borut.razem AT siol.net>
12088 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12090 2002-08-10 Borut Razem <borut.razem AT siol.net>
12091 * src/SDCCmain.c (main):
12092 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12093 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12094 The consequence was that some temporary files were not removed.
12097 unification of code in functions tempfilename() and tempfile():
12098 function tempnam() is defined in Visual Studio 6.0 and .NET
12100 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12102 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12103 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12104 - removed compiler command line option /WX: Treats all warnings as errors
12105 - update a list of source files, included into the project
12107 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12108 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12109 changed project type to Generic Project so that can be correcly converted to VS.NET project
12111 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12113 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12115 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12117 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12118 added return 0 statements after assert() to make compiler happy
12120 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12121 added newline in the def file to keep MSC compiler satisfied
12123 * sdcc/src/z80/gen.c:
12124 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12125 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12126 - solved MSC error in function aopDump()
12128 * sdcc_vc.h: define PREFIX as "\\sdcc"
12130 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12131 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12179 Added -p option. Allows port dependent processor to be specified.
12182 Initialized the new field char *Processor field to NULL in all ports
12185 Compiler generated registers for interrupt context saving
12186 were not getting allocated.
12188 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12191 Fixed left shift. Will promote the left side of a left shift
12192 if a) left shifting more than size of operand or b) when assigned
12193 to something size > size of left side

12303 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12305 * sdcc/src/SDCCloop.c:
12306 Previous fix was not good. basic blocks that have "break" or "return" are
12307 not really partof a loop , but live ranges used in these blocks should
12308 be live thru the entire loop, so set partOfLoop but don't add them to
12311 2002-02-21 <johan AT FRIJA>
12313 * src/SDCCcse.c: fixed bug #514308
12315 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
