[ARM] More MVE compare vector splat combines for ANDs

[llvm-complete.git] / test / CodeGen / ARM / 2016-05-01-RegScavengerAssert.ll

; RUN: llc < %s
; This test has around 4000 bytes of local variables and it also stresses register allocation
; to force a register scavenging. It tests if the stack is treated as "BigStack" and thus
; spill slots are reserved. If not, reg scavenger will assert.
