Abstract
The described embodiments include a processor that executes a vector instruction. The processor starts by receiving a vector instruction that optionally receives a predicate vector (which has N elements) as an input. The processor then executes the vector instruction. In the described embodiments, executing the vector instruction causes the processor to generate a result vector. When generating the result vector, if the predicate vector is received, for each element in the result vector for which a corresponding element of the predicate vector is active, otherwise, for each element of the result vector, the processor determines element positions for which a fault was masked during a prior operation. The processor then updates elements in the result vector to identify a leftmost element for which a fault was masked.
