; This test is reduced from the TSVC evaluation of vectorizers:
; https://github.com/llvm/llvm-test-suite/commits/main/MultiSource/Benchmarks/TSVC/LoopRerolling-flt/tsc.c
; Two loads and an fmul are expected to be vectorized to <2 x float>.
; Otherwise, performance will suffer on Cortex-A53.
; See https://bugs.llvm.org/show_bug.cgi?id=36280 for more details.
