Abstract:

SIMD vector units implement only a subset of the operations used by vectorizing compilers, and there are multiple conflicting techniques to legalize arbitrary vector types into register-sized data types. Traditionally, type legalization is performed using a set of predefined rules, regardless of the operations used in the program. This me...More
