Subject: [PATCH 02/20] tools build: Fix objtool build with clang
Date: Mon, 5 Dec 2016 18:37:50 -0300 [thread overview]
Message-ID: <20161205213808.6231-3-acme@kernel.org> (raw)
In-Reply-To: <20161205213808.6231-1-acme@kernel.org>
From: Peter Foley <pefoley2@pefoley.com>
Clang doesn't support multiple arguments being passed to -Wp, so split
them.
Fixes this error:
HOSTCC tools/objtool/fixdep.o
cat: tools/objtool/.fixdep.o.d: No such file or directory
