The test fails on arm-eabi when testing with the following settings: -mlittle-endian -mfloat-abi=hard -mcpu=cortex-a9 -mfpu=vfpv3
It only fails in the following torture option set: -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions
It also fails on numerous other 32-bit targets, but it depends on how the memcpy-like loop gets vectorized and unrolled.
I hope we can live with the XPASSes.
