[Qemu-devel] [PATCH v2 11/15] target/ppc: introduce GEN_VSX_HELPER_R2 macro to fpu_helper.c |
|
Date: |
Sun, 2 Jun 2019 12:08:59 +0100 |
Rather than perform the VSR register decoding within the helper itself,
introduce a new GEN_VSX_HELPER_R2 macro which performs the decode based
upon rD and rB at translation time.
