[PATCH v7 19/22] tcg/ppc: Update vector support for v2.07 FP |
Date: |
Mon, 30 Sep 2019 13:21:22 -0700 |
These new instructions are conditional on MSR.FP when TX=0 and
MSR.VEC when TX=1. Since we only care about the Altivec registers,
and force TX=1, we can consider these to be Altivec instructions.
Since Altivec is true for any use of vector types, we only need
test have_isa_2_07.
This includes moves to and from the integer registers.
