ARM post-submit SIMD sqrt/invsqrt test failure - Redmine #2261
Archive from user: Aleksei Iupinov
This has been broken for a while, since at least 18th September, where the Jenkins history stops. I’m not sure whether I missed some discussion on this.

Failing SIMD math function ulp comparison between refSqrt and sqrtSingleAccuracy
Requested ulp tolerance: 16
Requested abs tolerance: 0
Denormals can be 0: false
Largest Ulp difference occurs for x=2.6848277890087878e+38
Ref values: 1.6385444545141146e+19
SIMD values: 3.6968949829456626e+19
Ulp diff.: 10280507
etc.
