    PR tree-optimization/37021

    * tree-vect-data-refs.c (vect_check_strided_load): Allow

    REALPART/IMAGPART_EXPRs around the supported refs.

    * tree-ssa-structalias.c (find_func_aliases): Assume that

    floating-point values are not used to transfer pointers.



    * gfortran.dg/vect/fast-math-pr37021.f90: New testcase.
