3 * src/SDCCast.c (decorateType): partial fix for RFE 1475769,
4 remove cast to same type
6 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
8 Enabled VPATH feature: changed nearly all Makefiles (149 files).
9 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
11 One basic decision: e.g. src/clean.mk includes further files. In order
12 to make this work there are two solutions:
13 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
14 run configure on them. This way they can use
15 'include $(srcdir)/port-clean.mk'
16 - always include clean.mk by the Makefile at the same level. To avoid
17 that `make clean` tries to include and build Makefile.dep the
18 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
19 implemented, because now even `make uninstall` doesn't create
20 Makefile.in. clean.mk could be eliminated by pasting it in
23 * debugger/mcs51/Makefile.in: build own objects from library sources
24 (SLIB, SDCC) in current directory
26 * configure, configure.in: renamed --disable-device-lib-build in
27 --disable-device-lib; added --enable-doc, the required tools are
28 searched by configure; added result message; the toolchain for the
29 belonging ports are now only built, if the port is enabled.
31 * support/regression/*: all output is written in directory gen, because
32 the fwk and ports directories don't livet in the build tree using vpath
34 * doc/sdccman.lyx: renamed --disable-device-lib-build to
35 --disable-device-lib, added --enable-doc, added section VPATH
37 * sim/ucsim/configure.in,
38 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
39 z80 are enabled by default
41 2006-04-24 Raphael Neider <rneider AT web.de>
43 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to
44 config word, "pic14_"-prefixed some extern functions
45 (pic14_emitConfigWord): emit __config directive(s) if assignment to
46 config word has been found
47 * src/pic/device.h: added prototypes
48 * src/pic/pcode.c: added "pic14_"-prefix where needed
49 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic fixup

309 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
310 implemented patch 1120823 Thanks to Willy De la Court (normal

312 and enabled nesting of critical functions though not for gbz80
313 (genCritical, genEndCritical): added functions
314 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
315 * src/z80/mappings.i: added "ei" to all mappings

320 submitted by the Debian SDCC maintainer Aurelien Jarno:
321 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
322 archive with gcc 4.1 on mips and wrote the patch"
324 2006-03-16 Raphael Neider <rneider AT web.de>
326 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
327 the left operand is shorter than the result (c* = lit-c* + int),
329 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
332 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
334 * src/.version: increased version number to 2.5.5
335 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
336 linking is done manually in pic16 port's _linkEdit,
337 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
338 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
339 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
340 allocate asmop as AOP_ACC,
341 (aopForRemat): added parameter 'bool result' in function declaration,

354 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
355 call to allocReg, not by manually allocating a new one,
356 (pic16_assignRegisters): now before going through the register
357 allocating functions mark all registers as free. This eliminates some
358 side effects resulting from peephole parser done earlier in the backbone
360 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
362 * src/SDCCicode.c (geniCodeLogic),

407 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
408 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
410 2006-03-06 Borut Razem <borut.razem AT siol.net>
412 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
413 made the linker quiet
415 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
417 * src/pic16/gen.c (genPcall): fixed bug #1443644
418 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
419 which dumps before the function entry point a data byte which represents
420 the number of the local variables used by the specified function, added
421 'xinst' for initial support for Extended Instruction Support,
422 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
423 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
424 port->fun_prefix anymore (may change later),
425 (genFunction, genEndFunction): do not store/restore local registers for
426 _main (this should take care the --main-return command line option in
428 (genOr): removed some legacy pic-port instructions,
429 * src/pic16/genarith.c (genAddLit): re-enabled old code because
430 performing operations with SFR's causes data to be written more than
431 once to each SFR. Perhaps SFRs should be handled in special cases...
432 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
434 * src/pic16/main.c (_process_pragma): stack bound checking did not take
435 into account for stack starting position,
436 (struct OPTIONS pic16_optionsTable): added command line argument
437 --extended or -y for Extended Instruction Support,
438 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
439 (deassignLRs): *** perhaps the most important change, old 'for' code
440 (commented out for reference), didn't account for some registers which
441 were left marked 'not free' after a pointer operation. The change
442 reduces register usage a lot in some cases
444 2006-03-04 Borut Razem <borut.razem AT siol.net>
446 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

2717 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2718 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2719 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2720 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2721 always available in leading double underscore form. The C99 support is
2722 mostly missing, but it's a start.
2723 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2724 reserved identifier "__data".
2726 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2802 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2804 * device/lib/printf_large.c: removed inline assembly for portability and
2805 readability. Use printf_fast if speed or size are more important.
2806 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2807 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2809 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2811 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2812 prevent compiler warning
2814 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2816 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2817 moved to level 0 and declared as static. Also they are explicit
2818 placed in access bank. This was necessery because some times they
2819 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2820 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2821 optimizations. Currently only compare to unsigned char is implemented,
2822 * src/pic16/gen.c: added fReturnIdx array,
2823 * (struct resolvedIfx) is moved to gen.h and made public,
2824 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2825 * (aopForSym): added an optimization to directly store in stack of
2826 the operand of a SEND iCode,
2827 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2828 but as registers instead (AOP_REG) using the fReturnIdx array,
2829 * (pic16_freeAsmop): remove the freed register from the
2830 _G.sregsAlloc field,
2831 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2832 a compare of 'WREG',
2833 * (pic16_popGetTempRegCond): changed function prototype, now
2834 function takes also a bitVector argument v which holds the current
2835 set of registers that are allocated for stack access by aopForSym,
2836 registers allocated in aopForSym for accessing stack symbols are not
2837 any more part of the functions usedRegs field,
2838 * (genCall): some times aopOp is called for a stack variable to be
2839 send, aopForSym might perform the push, if this is true make sure
2840 that genCall doesn't push the variable twice by testing _G.resDirect,
2841 * (genFunction): changed testing for unspecified interrupt number
2842 from 256 to INTNO_UNSPEC,
2843 * modified selection scheme of frame pointer generation. Previously
2844 if function did use local registers a frame pointer was generated,
2845 now a frame pointer is generated only if function has arguments
2846 (that need PLUSW2 register access), or has stack arguments, or the
2847 compiler is not instructed to omit the frame pointer,
2848 * (genEndFunction): before restoring local registers that were saved
2849 in the function preamble, also restore the registers that *might*
2850 have been allocated for stack access,
2851 * (genRet): removed some old comments,
2852 * (genCmp, the active (RN's) version): added a call to the
2853 pic16_genCmp_special function to perform the compare with a more
2854 robust and optimized way,
2855 * (genInline): a feature has been added in inline code generation,
2856 which allows a wildcard variable substitution when writing inline
2857 assembly. Code is incomplete and experimental therefore undocumented,
2858 * (genCast): changed order of aopOp for result and right to allow
2859 aopForSym to directly load the result if possible,
2860 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2861 perform an optimized compare on some selected special occasions,
2862 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2863 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2864 generate an IVT any more,
2865 * src/pic16/main.c (pic16_optionsTable): added command line option
2867 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2868 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2870 * src/pic16/NOTES: Raphael Neider added in list of active developers
2871 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2872 jumptable_end to prevent bug #,
2873 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2874 inCond and outCond fields,
2875 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2876 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2877 turn off register spilling,
2878 * (packRegsForOneUse): synced with other ports' versions although it
2879 is not used currently,
2880 * (pic16_packRegisters): added an optimization while reading
2881 structure bitfields, some registers may be saved (malloc code is
2882 decreased by 80 bytes)
2884 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2886 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2887 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2888 this can be optimized more?
2890 2005-03-10 Raphael Neider <rneider AT web.de>
2892 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2893 genNearPointerGet): (hopefully) fixed access to bitfields via
2894 pointers (p->bitN = x; and x = p->bitN; failed)
2896 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3528 Adding support for replacing ljmps with sjmps in jumptables
3529 generated for switch statements. For now you need to set the
3530 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3531 Now 4 algorithms for mcs51 jumptable generation are used:
3532 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3533 addresses loaded pc-relative for up to 112 cases and stack-pushing
3534 target addresses loaded with offset from dptr for up to 256 cases.

3560 Large cummulative patch for pic16 port.
3561 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3562 to call when a stack overflow occurs,
3563 * (malloc.h): added CVS Id tag,
3564 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3566 * added libc directory. The current version of LibC contains string
3567 functions, ctype functions and macros and some functions of the
3568 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3569 be extensively tested in the future. Standard disclaimer here.
3570 Library is not automatically build yet. But one can build it by
3571 invoking 'make' inside the libc directory.
3572 * added ADC library under libio. Preliminary version yet.
3574 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3581 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3582 * (pic16_storeForReturn): optimized return of 0,
3583 * (genCmp): experimental code for new genCmp which uses PIC18's
3584 special compare&skip instructions. Initial tests fail some times
3585 with variables grater than 1 byte in size, so new code is disabled,
3586 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3588 * (genCast): began a fix to optimize the casting of a bit to another
3589 bit, now assigning a bitfield to another bitfield will fail, sorry,
3590 * src/pic16/main.c: disabled the use of lr-support feature,
3591 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3594 bits with offset (case PO_GPR_BIT),
3595 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3597 * (isBankInstruction): modified to return 0 for no banking instruction,
3598 and 1 for banking instruction,
3599 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3600 caused stop processing pCodes after a inline assembly block,
3601 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3602 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3603 registers when it shouldn't,
3604 * src/pic16/ralloc.c (allocReg): add preliminary support for
3605 supporting a limited set of temporary registers,
3607 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3609 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3610 genDataPointerSet): ensure assignments always copy in MSB to LSB
3612 (loadRegFromAop): recognize CLRH optimization,
3613 (genFunction): optimize RECEIVE iCodes in reentrant functions
3615 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3617 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6544 * src/pic/glue (pic14emitRegularMap),
6545 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6547 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
6549 * src/pic/pcode.c (PCodeID): commented out left over debug code
6551 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
6553 * support/valdiag/tests/overflow.c: added shift tests
6561 * src/pic/pcodepeep.c,
6562 * src/pic/pcoderegs.c,
6564 * src/pic/ralloc.h: applied patch from Slade Rich;
6565 added support for multiple code pages and multiple RAM banks on the
6566 PIC 14 port. The ASM files now no longer simply assume all the
6567 code / RAM are in the same page / bank. This means the linker can
6568 safely allocate code/RAM of separate ASM files to different pages/banks.
6569 * doc/sdccman.lyx: added Slade's tips
6570 * src/mcs51/peeph.def: fixed bug #880768

6579 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6582 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6583 strtof is not part of C89 and isn't included with Mac OS X.
6585 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6587 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6612 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6614 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6615 loaded with the linker search paths (-L arguments) and the libraries
6616 to be linked with the current source (-l arguments). Changes
6617 currently will affect only the pic16 port.
6618 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6619 include path the port specific paths and port specific libraries,
6620 * gplink command now contains the $3 argument,
6621 * src/pic16/device.h,
6622 * src/pic16/device.c,: structure PIC_device is made public and
6623 renamed to PIC16_device, the same for variable Pics which is renamed
6624 to Pics16. Updated all references to them.
6625 * src/pic16/glue.c (pic16glue): corrected bug with code
6626 initialization which bypassed the variable initializations block.
6628 * device/lib/pic16/Makefile.rules: removed --penable-stack from
6629 COMPILE_FLAGS and added the --nostdinc option
6631 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6636 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6638 Documenting changes from previous commits.
6639 * configure.in (version 1.56),
6640 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6641 when generating output files to configure the pic16 library,
6642 but now I've commented it out, since gputils aren't installed in the
6643 SF compile farm, so library won't compile
6645 * device/lib/Makefile.in (version 1.56): initially I've added in
6646 target 'all' the prerequestive 'model-pic16' so it compiled the
6647 pic16 library, but now I've commented it out for the same reasons
6649 * added targets 'model-pic16' and 'objects-pic16' to compile the
6651 * added target 'port-specific-objects-pic16' to handle the
6652 generated libraries and copy them into the build/ directory
6653 * added target 'clean-intermediate-pic16' to clean intermediate
6654 files into pic16 directory
6655 * in target 'installdirs' added line to create directory pic16 in
6656 the installation path
6658 * device/include/Makefile.in (version 1.11): in target 'install'
6659 added lines to copy all header files to installation path,
6660 * in target 'installdirs' added line create directory for pic16
6661 headers in the installation path

6676 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6677 option so that it actually works. Made it specific to the z80, since
6678 the gbz80 doesn't have these kinds of I/O ports.
6680 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6682 * device/include/z180.h,

6704 Mainly changes to support compilation of the device libraries
6705 * src/pic16/device.c: stack is allocated via symbol and not
6706 via literal number. The symbol is placed in the corresponding
6707 position of the data ram
6708 * (pic16_dump_section): relocatable and absolute uninitialized
6709 data are now emitted in sorted order to reduce section naming,
6710 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6711 weren't marked as being in the access bank,
6713 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6715 Added portion of GNU PIC Library under the directory
6716 device/include/pic16 and device/lib/pic16. These files
6717 contain the declarations of SFRs for the PIC18Fxx2 devices.
6718 The directory is initialized via configure from toplevel.
6720 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6722 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6748 all over. Telling LaTeX to be less strict with word spacing
6749 to better keep the right margin. Changed some notes about
6750 maintainance of the ports in section 3.2.1 - is it OK like this?
6752 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6790 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6792 * src/pic16/peeph.def: all peepholes with movff are commented out,
6793 because there is a problem in the pcode peep optimizer,
6794 * src/pic16/ralloc.c: the register allocator can now reuse local

6946 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6948 PIC16 port related changes:
6949 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6950 added variable stackPos,
6952 * gen.c: genCall, assignResultValue: added support for
6953 pushing/retrieving function parameters to/from stack,
6954 genFunction,genEndFunction: setup stack frame for the
6956 genAddrOf: will be changed according to bug 863624
6958 * added files genutils.c and genutils.h which contain gen*
6959 debugged and optimised functions extracted from gen.c
6961 * glue.c: added variable 'externs' which holds extern symbols,
6962 pic16emitRegularMap: is modified to properly handle relocatable
6963 symbols under the new scheme,
6964 pic16createInterruptVect: is modified
6965 pic16printPublics: is modified to emit 'global' assembler directives,
6966 added pic16_printExterns to print extern symbols,
6967 pic16glue: initializes stack/frame pointer in the beginning of
6968 the assembly output. Temporary hack, will be corrected later,
6969 because gplink yet does not support stack and SDCC does not
6970 yet support a type of crt0.o object to create the final binary.
6972 * Removed many lines that contain 8051 legacy code.
6973 * The code is finally placed under a 'code' directive.
6974 * Added port specific options.
6976 * _process_pragma: simplified since now we do not need *special*
6977 include file to define SFR registers. But a separate header
6978 will be needed. This will be developed later.
6979 * _pic16_parseOptions: added, parses port specific options:
6980 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6981 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6982 --preplace-udata-with=
6984 * _pic16_setDefaultOptions: modified to initialize section names,
6985 but hack is temporarly out of order since it needs improvement.
6986 * _pic16_genAssemblerPreamble: configuration words are emitted by
6987 their address instead of their name. This part is incomplete and
6988 supports only the 18Fxx2 devices. Other devices will emit an error
6989 during assembly since they do not contain the same set of config
6991 * _pic16_genIVT: is modified,
6993 * pcode.c: added definitions for some hardware registers that are needed
6995 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6996 All PCI entries are updated. Now LFSR is supported.
6997 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6998 * added pic16_newpCodeOpLit2 to support instructions with
6999 two literal arguments
7000 * pic16_pCode2str: corrected code that emits assembler instructions
7001 with two literal operands and those that have an access bit modifier
7002 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7003 this fixes a bug which caused some labels to be lost, when an
7004 assembler directive was added, i.e. banksel,
7005 * pic16_FixRegisterBanking: improved logic that causes the insertion
7007 * InlineFunction: functions that are called once, are not any more
7008 inlined. This can be a port option in the future,
7010 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7012 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7013 hold the corresponding uninitialized symbols,
7014 * pic16_allocProcessorRegister: registers have explicit marked the
7016 * pic16_allocInternalRegister: registers are explicit marked as
7018 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7019 processing list, so bit registers were lost,
7022 * ralloc.h: added field 'accessBank' and original symbol operand
7023 in register definition,
7024 * removed the field isMapped from register definition,
7026 ** Several functions have been removed from various sources:
7027 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7028 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7029 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7030 pic16_assignRelocatableRegisters
7032 ** others have been introduced:
7033 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7034 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7036 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7038 * support/scripts/inc2h.pl: changed definition of BIT_AT
7039 to emit 'sbit at' instead of 'bit at'. This was a request.
7041 PIC16 port related preliminary changes:
7042 * gen.c: prefixed function popRegFromString with
7043 pic16_ and all references to it corrected
7044 * pcode.c: all pic16_pc_* hardware registers prefixed
7045 with underscore (_),
7046 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7047 * ralloc.c: newReg(): when register is REG_SFR then
7048 set address to rIdx,
7049 pic16_allocProcessorRegister(): marks register wasUsed=0
7050 pic16_writeUsedRegs(): added a call to assign processor
7051 registers via pic16_assignFixedRegisters
7053 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7055 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7056 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7057 variables in unused register banks. Also the SSEG is placed
7058 wherever there is enough space for it, and IDATA can be anywhere
7059 in internal RAM. For now compile using -Wl-Y[stack_size].
7060 The mem file is different for this option as well, since it
7061 makes no sense of talking about DSEG lenght.
7063 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7065 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7310 * src/SDCCast.c (decorateType): disabled a transformation I added in
7311 revision 1.188 (access to fields of a structure at an absolute address);
7312 it breaks with bitfields, extern declarations, and gcse analysis.
7313 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7314 could be assigned through a pointer, so don't complain.

8038 reported in bug #800609
8040 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8042 * Top header beautifications in src/pic16 directory:
8043 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8044 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8045 pcoderegs.h, ralloc.c, ralloc.h
8046 * main.c: added top header and GPL license notice
8047 * pcode.c: fixed the if-conditional warning
8049 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8051 * device/lib/_mullong.c: replaced int by short for gcc
8053 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8055 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8056 and JUMPTABLE iCodes properly now (worked by accident before)
8057 * src/mcs51/gen.c (leftRightUseAcc),
8058 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8059 iCode properly now. Use getSize instead of nRegs since a & b
8060 aren't part of the nRegs tally.
8062 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8064 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8065 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8066 before instructions that use the _STATUS register
8068 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8070 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8071 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8072 fetching of the pointer
8073 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8074 copied from genNearPointerSet()
8075 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8076 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8077 If they pop r0/r1 they must be called in the opposite order than aopOp().
8078 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8079 (resp. --stack-auto), prepared for --xstack
8081 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8085 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8087 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8088 these ports have their own __sdcc_external_start()
8090 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8092 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8093 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8094 type for bits was changed. It resulted in bit variables becoming
8095 global, which is not permitted in PIC 14 assembly output.
8097 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8099 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8101 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8103 Z80 and MCS51 linkers complaint if a public symbol is defined
8104 in more than one library module:
8108 * as/mcs51/Makefile.in
8110 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8112 A few small changes that speed up the peephole optimizer.
8116 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8118 Try to make the peephole optimizer smarter by maintaining
8119 an association between the assembly source code and the
8120 iCodes that originated them. Put this information to use
8121 with a new peephole rule condition "notVolatile" so that
8122 the rules can be aggressive yet still safe.
8127 * src/mcs51/peeph.def
8129 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8133 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8134 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8135 if the left or right operand symbols have the accuse flag set.
8137 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8139 Changed the type of the result of the ! (NOT) operator to char;
8140 previously it returned the same type as the source. This allows
8141 us to eliminate all the genFloatNot functions (all of its target
8142 implementations were very buggy) since !float can use the same
8145 * src/SDCCicode.c (ast2iCode): ! returns char
8146 * src/mcs51/gen.c (genNot, genNotFloat),
8147 * src/ds390/gen.c (genNot, genNotFloat),
8148 * src/z80/gen.c (genNot, genNotFloat),
8149 * src/pic/gen.c (genNot, genNotFloat),
8150 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8152 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8154 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8155 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8156 during interrupts. Ensure WSAVE is located at a shared bank address.
8157 2. Fixed page selection in some places
8158 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8159 the registers name strings.
8160 4. Fixed "signed / unsigned compare" compiler warnings.
8161 5. The PIC port manages its own allocation of the general purpose
8162 registers, but makes no attempt to reuse them. As a result when
8163 compiling it soon runs out of general purpose registers. Some
8164 additional code was added to the files pcode.c and device.c to walk
8165 through the function call tree and rename the registers so that they
8175 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8176 genPlus() & genMinus() when the result is the same as left or right
8178 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8182 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8184 Made bitfield a distinct type from bit so that bitfields
8185 convert as per ANSI C and bits retain their traditional
8186 boolean style behaviour. Implemented bitfield support in
8194 * src/ds390/gen.c: bit v bitfield split
8195 * src/z80/gen.c: New support for bitfields
8196 * support/regression/tests/bitfields.c: reenabled z80,
8199 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8201 Rules 246.x, 247.x relate to bitfields, the others speed up
8202 access to xdata mapped I/O devices.
8204 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8206 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8208 Cleaned up genPackBits and genUnpackBits and added two helper
8209 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8210 for literal assignments in genPackBits (thanks to Frieder for
8216 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8218 Fixed bug #748310 (pointer to function type mishandled when the
8219 function name is omitted). Also fixed a SIGSEGV when a function
8220 attribute (reentrant, etc) is used on a non-function or on a
8221 function but misplaced before the parameter list.
8223 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8225 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8226 * support/Util/SDCCerr.h,
8227 * support/Util/SDCCerr.c: Added func attr misuse error msg
8229 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8231 Fixed bug #787649 by anonymous
8232 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8248 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8250 Made the constant following the "interrupt" keyword optional. If
8251 omitted, the function will not automatically be given an entry
8252 in the interrupt vector table (similar to #pragma NOIV, but
8253 less syntacticly kludgy). The interrupt number is also now
8254 range checked. Also fixed a bug in the high order bit example
8261 * support/Util/SDCCerr.c
8262 * support/Util/SDCCerr.h
8265 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8267 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8268 * src/SDCCicode.c (operandOperation): rewritten some ops
8269 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8270 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8272 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8273 be re-activated by defining REDUCE_LITERALS)
8274 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8275 unsigned, but are signed by default
8276 * src/SDCCval.c (constVal): rearranged
8277 * src/SDCCval.c (valMod): preliminary fix
8278 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8321 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8322 * src/SDCCval.c (valDiv, valMod): fixed signdness
8323 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8324 signedness of modulo, left and right shift

8730 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8731 the regression tests I'm not brave enough to enable 245.b, 245.c
8732 * doc/sdccman.lyx: added latex preamble for hyperref package.
8733 Using pdflatex this will give you a hyperlinked pdf file with
8734 bookmarks. (prepend '%' before /usepackage if this breaks something)

8772 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8774 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8775 it can be defined with CFLAGS when running configure
8776 * src/SDCCmain.c: fixed compiling + linking with object files
8778 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8781 added --disable-pic16-port
8782 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8783 * src/SDCCmain.c: linkOptions is changed to set *,
8784 added if/endif conditional macros to remove options help
8785 messages from optionsTable when a port is not configured, added
8786 support for the PIc16 port in the ports table, when executing
8787 the compiler with no port specified on command line, a default
8788 port is selected with the new macro DEFAULT_PORT which is
8789 defined in port.h, in setDefaultOptions() linkOptions is removed
8790 from initialization assignment, since now it is a set,
8791 parseCmdLine uses setParseWithComma for linkOptions, in
8792 linkEdit() linkOptions are accessed with new function indexSet()
8793 which returns the i'th item of a set variable. See SDCCset.c, in
8794 linkEdit() when calling buildCmdLine(), added linkOptions as
8795 last argument. Now users can pass arguments to gplink via the
8796 -Wl option, main() uses pic16glue() to glue up pic16 programs

8808 * src/pic16/glue.c: commented out some error producing lines
8809 * src/pic16/main.c: __config directives are commented out to stop
8810 gpasm complaining and test the linkage with gplink, _linkCmd and
8811 _asmCmd changed to be more gplink and gpasm friendly
8812 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8813 produced an error when parsed, peep rule 12 is added to utilize
8814 movff, but it is commented out since the pCode does not support
8815 yet a command with 2 address arguments
8817 2003-05-18 <johan AT balder>
8819 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8820 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8844 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8846 2003-05-11 Borut Razem <borut.razem AT siol.net>
8848 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8849 the path of bin directory, so that PATH is the only env. variable, which has to be set
8850 in case of standard installation.
8851 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9883 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9884 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9885 following files to include the previous two files: aslink.dsp,
9886 Makefile.aslink, Makefile.bcc, and Makefile.in.
9888 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9889 .adb instead of .cdb
9891 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9893 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9894 value from option --iram-size.
9896 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9898 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9901 2002-09-18 <wiml AT hhhh.org>
9903 * SDCClrange.h: exposed setFromRange() and setToRange()
9904 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9905 packRegsForAccUse() (bug 542397)
9906 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9907 multiple times and emitting the fetch operations more than once
9908 added aopGetUsesAcc() function to allow binary operators to
9909 fetch their operands in the correct order; made genMinus() emit
9910 compact code for X = LITERAL - Y
9912 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9913 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9914 sprintf() in line 1267.
9916 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9917 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9920 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9921 Changes to aslink (All the changes are marked with 'JCF'):
9923 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9926 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9927 area BSEG. Also moves, if possible, the DATA area down into the internal
9928 ram so more space is available.
9930 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9933 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9934 not bytes. Function summary() which creates a memory usage summary
9935 file with extension .mem. Reports of overlaping stack and small stack
9936 size. If the space for the stack is less than 16 bytes aslink trows a
9939 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9940 the 8051. Option 'y' for memory summary output file.
9942 Changes to sdcc (All the changes are marked with 'JCF'):
9944 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9946 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9947 overlaying area for it (uses RegBankUsed[4]).
9949 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9950 bank zero as used by default. By default aslink locates the stack
9951 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9952 the creation of the .mem file. Delegates the allocation of data area
9953 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9954 the begining of the stack area to aslink.
9956 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9957 glue() in SDCCglue.c creates an area for it.

9960 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9961 sdcc/src/pic/glue.c:
9962 introduced atexit() handler for teporay files removal in case of
9963 errors, assertions, ...
9965 2002-08-29 Borut Razem <borut.razem AT siol.net>
9966 * sdcc/support/cpp2/auto-host_vc_in.h:
9967 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9968 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9969 Maybe there is a similar problem with BORLANDC? It should be checked!
9971 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9972 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9973 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9974 was not executed, and the compiler (cl) launched a warning:
9975 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9977 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9978 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9980 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9981 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9983 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9984 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9985 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9986 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9987 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9988 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9989 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9990 - added Release configuration in VS projects
9991 - review of compiler an linker options
9992 - VC .exe files are generated in bin_vc directory, not to interfere
9993 with binaries generated from other projects (cygwin, mingw, bcc ...)
9995 * sdcc/src/yacc.dsp: added
9997 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9998 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9999 and insert the version number definitions from .version
10001 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10003 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10004 added - genarate auto-host.h using auto-host_vc_in.h as template
10007 removed from CVS, generated automatically
10009 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10010 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10012 2002-08-11 Borut Razem <borut.razem AT siol.net>
10013 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10015 2002-08-10 Borut Razem <borut.razem AT siol.net>
10016 * src/SDCCmain.c (main):
10017 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10018 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10019 The consequence was that some temporary files were not removed.
10022 unification of code in functions tempfilename() and tempfile():
10023 function tempnam() is defined in Visual Studio 6.0 and .NET
10025 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10027 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10028 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10029 - removed compiler command line option /WX: Treats all warnings as errors
10030 - update a list of source files, included into the project
10032 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10033 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10034 changed project type to Generic Project so that can be correcly converted to VS.NET project
10036 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10038 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10040 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10042 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10043 added return 0 statements after assert() to make compiler happy
10045 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10046 added newline in the def file to keep MSC compiler satisfied
10048 * sdcc/src/z80/gen.c:
10049 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10050 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10051 - solved MSC error in function aopDump()
10053 * sdcc_vc.h: define PREFIX as "\\sdcc"
10055 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10056 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10059 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10060 - Rewrote the register banking algorithm.
10061 - Added pCode live-range analysis to registers (for now, only non-used and
10062 singly-used registers optimized away)
10064 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

10093 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10095 2002-03-28 Johan Knol <johan AT balder>
10097 * src/SDCCval.c: fixed bug #532436
10099 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10228 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10230 * sdcc/src/SDCCloop.c:
10231 Previous fix was not good. basic blocks that have "break" or "return" are
10232 not really partof a loop , but live ranges used in these blocks should
10233 be live thru the entire loop, so set partOfLoop but don't add them to
10236 2002-02-21 <johan AT FRIJA>
10238 * src/SDCCcse.c: fixed bug #514308
10240 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
