Vectorization of shaders
Abstract:
Intermediate representation (IR) code is received as compiled from a shader in the form of shader language source code. The input IR code is first analyzed during an analysis pass, during which operations, scopes, parts of scopes, and if-statement scopes are annotated for predication, mask usage, and branch protection and predication. This analysis outputs vectorization information that is then used by various sets of vectorization transformation rules to vectorize the input IR code, thus producing vectorized output IR code.
