re PR tree-optimization/37021 (Fortran Complex reduction / multiplication not vectorized)
2013-03-27 Richard Biener <rguenther@suse.de>
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.
