tests_lit/llvm2ice_tests/vector-cast.ll

; This file tests casting / conversion operations that apply to vector types.
; bitcast operations are in vector-bitcast.ll.

; 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.
