Subject: [PATCH] drm/amdgpu/dc: don't pass -mhard-float to clang
Date: Tue, 5 May 2020 16:24:56 +0200 [thread overview]
Message-ID: <20200505142519.1138945-1-arnd@arndb.de> (raw)
Clang does not appear to care, and instead prints a warning:
clang: warning: argument unused during compilation: '-mhard-float' [-Wunused-command-line-argument]
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
