From 84774cc37f2c17e48a4867a8e8e055deb23bea69 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 24 Feb 2020 14:22:22 -0800 Subject: [PATCH] target/arm: Replace ARM_FEATURE_VFP3 checks with fp{sp, dp}_v3 Sort this check to the start of a trans_* function. Merge this with any existing test for fpdp_v2.
