Subject: [PATCH] LLVMLinux: Change DWARF flag to support gcc and clang
Date: Sat, 22 Mar 2014 08:50:47 -0700 [thread overview]
Message-ID: <1395503447-17003-1-git-send-email-behanw@converseincode.com> (raw)
From: Behan Webster <behanw@converseincode.com>
Both gcc (well, actually gnu as) and clang support the "-Wa,-gdwarf-2" option
(though clang does not support "-Wa,--gdwarf-2"). Since these flags are equivalent
in meaning, this patch uses the one which is better supported across compilers.
Signed-off-by: Behan Webster <behanw@converseincode.com>
