--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
First of all we fail to if-convert because we think
iftmp.0_9 = VIEW_CONVERT_EXPR<unsigned char[32]>(a)[i_15];
tree could trap...
which is because we're concerned about out-of-bound access of 'a' and treat
this as a array-at-struct-end.
