From f0cd49c501a98050f8b2c71b6866f57e94a4c1c6 Mon Sep 17 00:00:00 2001 From: Richard Earnshaw Date: Fri, 16 Jun 2017 21:04:52 +0000 Subject: [PATCH] [arm] Explicitly set .fpu in cmse_nonsecure_call.S This file is missing a .fpu directive and was relying on the compiler driver passing through a -mfpu= command line option. When the FPU is auto, that will not be passed through correctly, so set something suitable within the file itself. libgcc: * config/arm/cmse_nonsecure_call.S: Explicitly set the FPU.
