[PATCH v3 02/25] target/ppc: Implement vclzdm/vctzdm instructions |
Date: |
Thu, 4 Nov 2021 09:36:56 -0300 |
From: Matheus Ferst <matheus.ferst@eldorado.org.br>
The signature of do_cntzdm is changed to allow reuse as GVecGen3i.fni8.
The method is also moved out of #ifdef TARGET_PPC64, as PowerISA doesn't
say vclzdm and vctzdm are 64-bit only.
