Subject: [PATCH 1/3] csky: Select ARCH_WANT_FRAME_POINTERS only if compiler supports it
Date: Thu, 16 Sep 2021 21:38:36 -0700 [thread overview]
Message-ID: <20210917043838.3514789-2-linux@roeck-us.net> (raw)
In-Reply-To: <20210917043838.3514789-1-linux@roeck-us.net>
Compiling csky:allmodconfig with an upstream C compiler results
in the following error.
csky-linux-gcc: error:
unrecognized command-line option '-mbacktrace';
did you mean '-fbacktrace'?
Select ARCH_WANT_FRAME_POINTERS only if gcc supports it to
avoid the error.
