The LASTB and LASTA instructions extract the last active element, or element after the last active, from the source vector. The added variants are: Scalar: last(a|b) w0, p0, z0.b last(a|b) w0, p0, z0.h last(a|b) w0, p0, z0.s last(a|b) x0, p0, z0.d SIMD & FP Scalar: last(a|b) b0, p0, z0.b last(a|b) h0, p0, z0.h last(a|b) s0, p0, z0.s last(a|b) d0, p0, z0.d The CLASTB and CLASTA conditionally extract the last or element after the last active element from the source vector. The added variants are: Scalar: clast(a|b) w0, p0, w0, z0.b clast(a|b) w0, p0, w0, z0.h clast(a|b) w0, p0, w0, z0.s clast(a|b) x0, p0, x0, z0.d SIMD & FP Scalar: clast(a|b) b0, p0, b0, z0.b clast(a|b) h0, p0, h0, z0.h clast(a|b) s0, p0, s0, z0.s clast(a|b) d0, p0, d0, z0.d Vector: clast(a|b) z0.b, p0, z0.b, z1.b clast(a|b) z0.h, p0, z0.h, z1.h clast(a|b) z0.s, p0, z0.s, z1.s clast(a|b) z0.d, p0, z0.d, z1.d Please refer to the architecture specification for more details on the semantics of the added instructions. llvm-svn: 336783 |
