atomicReadIntArray# :: MutableByteArray# d -> Int# -> State# d -> (# State# d, Int# #)ghc-internal GHC.Internal.Exts Given an array and an offset in machine words, read an element. The index is assumed to be in bounds. Implies a full memory barrier. Warning: this can fail with an unchecked exception.
