tests_lit/llvm2ice_tests/vector-bitcast.ll

; This file tests bitcasts of vector type. For most operations, these
; should be lowered to a no-op on -O2.

; TODO(jvoung): fix extra "CALLTARGETS" run. The llvm-objdump symbolizer
; doesn't know how to symbolize non-section-local functions.
; The newer LLVM 3.6 one does work, but watch out for other bugs.
