Subject: -fno-PIE, take #3
Date: Fri, 4 Nov 2016 19:39:37 +0100 [thread overview]
Message-ID: <20161104183940.30692-1-bigeasy@linutronix.de> (raw)
Debian gcc's is nowdays compiled with --enable-default-pie which means it does
-fPIE by default. This breaks atleast x86-64 compiles.
This is the third attempt to fix it, this time by using runtime detection of
the -fno-PIE compiler switch (it was introduced in gcc 3.4, min required gcc is
currently 3.2) so it can be backported to the stable kernels.
As noted by Al this won't fix `git bisect' of stable kernels prio this commit.
However using always a wrapper around gcc which adds -fno-PIE is not sollution
I want to rely in future.
Sebastian
