; This test is reduced from the matrix multiplication benchmark in the test-suite:
; https://github.com/llvm/llvm-test-suite/tree/master/SingleSource/Benchmarks/Misc/matmul_f64_4x4.c
; The operations here are expected to be vectorized to <2 x double>.
; Otherwise, performance will suffer on Cortex-A53.
