Error description

  • Compiling a test case with option combinations of -O3
    -qarch=pwr7 -qfloat=nofold -qsimd=auto -qsmp=omp -qrealsize=8
    results in Internal Compiler Error.
    
    This is a corner case, removing any of the option or using -O2
    will compile fine.
    

Local fix

  • Remove any of the option;
    Use -O2
    

Problem summary

    -qsmp=omp -qrealsize=8 are used together.
    

Problem conclusion

  • This is a corner case when -qfloat=nofold -qsimd=auto -qsmp=omp
    -qrealsize=8 are used together, especially, using
    -qfloat=nofold. The problem is fixed.
