From 173b711e83d7b61a46f55eb44f03ea98f69a1dd6 Mon Sep 17 00:00:00 2001 From: Momchil Velikov Date: Thu, 9 Jan 2020 13:47:52 +0000 Subject: [ARM][MVE] MVE-I should not be disabled by -mfpu=none Architecturally, it's allowed to have MVE-I without an FPU, thus -mfpu=none should not disable MVE-I, or moves to/from FP-registers. This patch removes `+/-fpregs` from features unconditionally added to target feature list, depending on FPU and moves the logic to Clang driver, where the negative form (`-fpregs`) is conditionally added to the target features list for the cases of `-mfloat-abi=soft`, or `-mfpu=none` without either `+mve` or `+mve.fp`. Only the negative form is added by the driver, the positive one is derived from other features in the backend.
