[vector] Add Identity/Ideal transformations for vector logic operations

    XMLWordPrintable

Details

    • b05

    Description

      Add optimizations for vector logic operations like "AndV, OrV, XorV", incuding:
        (AndV v (Replicate m1)) => v
        (AndV v (Replicate zero)) => Replicate zero
        (AndV v v) => v

        (OrV v (Replicate m1)) => Replicate m1
        (OrV v (Replicate zero)) => v
        (OrV v v) => v

        (XorV v v) => Replicate zero

      And the same optimizations for vector mask logic operations (i.e. "AndVMask, OrVMask, XorVMask").
