Subject: [PATCH, rs6000] Add support for xxpermr and vpermr instructions
Authentication-results: sourceware.org; auth=none

This patch adds support for two new Power9 instructions, xxpermr andvpermr, providing more efficient vector permutation operations onlittle-endian configurations. These new instructions are described inthe Power ISA 3.0 document. Selection of the new instructions isconditioned upon TARGET_P9_VECTOR and !VECTOR_ELT_ORDER_BIG.

The patch has bootstrapped and tested on powerpc64le-unknown-linux-gnuand powerpc64-unknown-linux-gnu with no regressions. Is this ok for GCC7 when stage 1 opens?


Thanks.
