APAR status

  • Closed as program error.

Error description

  • The IPA component of the compiler is encountering an internal
    error when processing a local array that is used as a parameter
    for a function call.
    
    The issue occurs when the -qipa=level=2 option is enabled (set
    by default with -O5), and the build is 64-bit (-q64).
    
    During the IPA link step, an error similar to the error below is
    output:
    
    
    $ xlc  -qipa=level=2 -q64 myobj1.o myobj2.o -V
    export XL_CONFIG=/etc/vac.cfg.53:xlc
    export XL_BACKEND=/usr/vac/exe/xlCcode
    export XL_LINKER=/bin/ld
    ipa64 -link -V -qosvar=aix.5.3 -qipa=level=2 -q64 -b64
    -qlargetype -b64 /lib/crt0_64.o -bpT:0x100000000
    -bpD:0x110000000 myobj1.o myobj2.o -L/usr/lpp/xlC/lib/aix53
    -L/usr/lib -L/usr/vac/lib -L/usr/vac/lib -lxlopt -lxlipa -lxl
    -lc
        1500-004: (U) INTERNAL COMPILER ERROR while compiling main.
    Compilation ended.  Contact your Service Representative and
    provide the following information: Internal abort. For more

    1586-346 (U) An error occurred during code generation.  The code
    generation return code was 1.

Local fix

  • Avoid IPA usage.  The -qipa option can be removed, or the
    -qnoipa option can be added.
    

Problem summary

  • PROBLEM DESCRIPTION:
    Internal compiler error and runtime failures due to data
    reorganizations.
    
    USERS AFFECTED:
    Users of IPA at -O5 or -qipa=level=2.
    

Problem conclusion

  • The issue has been fixed.
