Subject: [Bug target/36756]  New: g++.dg/tls-3.C ICE with section-anchors, unit-at-a-time, no-toplevel-reorder
Date: Mon, 07 Jul 2008 21:22:00 -0000	[thread overview]
Message-ID: <bug-36756-4503@http.gcc.gnu.org/bugzilla/> (raw)

Test g++.dg/gomp/tls-3.C started failing on powerpc-unknown-linux-gnu with an
ICE in rs6000_emit_move when the -O0 defaults were changed for
-funit-at-a-time, -fsection-anchors, and -ftop-level-reorder.  This smaller C
test:

__thread int i;
int
foo ()
{
  static __thread int k;
  return k;
}

gets the same ICE for earlier compilers back to 4.2.0 (when section anchors
were added) when compiled with "-funit-at-a-time -fsection-anchors
-fno-toplevel-reorder".
