--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> ---
Eh.

make check-gcc RUNTESTFLAGS="--target_board=unix/-flto/-ffat-lto-objects
gomp.exp"

FAIL: gcc.dg/gomp/declare-simd-1.c (internal compiler error)
FAIL: gcc.dg/gomp/declare-simd-1.c (test for excess errors)

But otherwise clean.

/space/rguenther/src/svn/trunk/gcc/testsuite/gcc.dg/gomp/declare-simd-1.c:100:1:
internal compiler error: tree code 'omp_clause' is not supported in LTO
streams^M
0xa6dbe4 lto_write_tree^M
        /space/rguenther/src/svn/trunk/gcc/lto-streamer-out.c:376^M

seems like FUNCTION_DECLs now refer to OMP_CLAUSE?  Ah... via attributes :/

Jakub - please add tree streaming support for the relevant required stuff.
