[Michael Hope (michaelh1)]

The results for ARMv5, Cortex-A9, i686, and x86_64 all agree.

There's one new timed out program in the A9 build:
 FAIL: gcc.c-torture/compile/limits-fndefn.c -O3 -g (test for excess errors)

This is a limit test. The same fault at least occurs in gcc-4.6+svn178710 to gcc-4.6+svn179644. I believe the fault exists upstream but the previous build happened to pass it.

[Ulrich Weigand (uweigand)]

The limits-fndefn test is borderline hitting the 5 minute timeout, so this may just have been bad luck this time.

The patch is OK.

review: Approve

[Michael Hope (michaelh1)]

On an idle machine, limits-fndefn.c takes 17:31 of its 20 minute limit. A parallel test would push this over the edge.
