--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note the thread_local10.C test fails on the 4.8 branch.
The problem is that the 4.8 branch doesn't contain the
https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/testsuite/g%2B%2B.dg/plugin/plugin.exp?r1 8416&r2 8415&pathrev 8416&limit_changes=0&view=patch
the change and thus if plugin.exp is run before tls.exp, the default flags
include -ansi.
Jason, do you think that change (just the plugin.exp one) is ok for 4.8.4, or
alternatively we can add something like
// { dg-options "" }
to the test.

I believe that is correct though.
If you have -fPIC, it means the sa or sb arrays could be interposed, and they
can have a different alignment then, so you can't rely on the increased
alignment.
So, either those tests should use
/* { dg-require-effective-target nonpic } */
or could e.g. use hidden visibility, or make the arrays static.
E.g.

@@ -5,8 +5,8 @@
#define N 128
-short sa[N];
-short sb[N];
+static short sa[N];
+static short sb[N];
__attribute__ ((noinline))
int main1 ()
works fine for me. What other tests behave similarly?
