; This test is reduced from the TSVC evaluation of vectorizers:
|
|
; http://www.llvm.org/viewvc/llvm-project/test-suite/trunk/MultiSource/Benchmarks/TSVC/LoopRerolling-flt/tsc.c?view=log
|
|
; 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.
