------- Comment #12 from rguenth at gcc dot gnu dot org 2010-04-30 09:00 -------
With the last patch we are down to
=== libstdc++ tests ===
Running target unix/-fipa-pta/
FAIL: 23_containers/bitset/operations/1.cc execution test
FAIL: 23_containers/bitset/to_ullong/1.cc execution test
plus some gfortran procedure pointer tests (might be invalid or require
-fwhole-file to work) and
FAIL: gcc.c-torture/execute/frame-address.c execution, -O2
which is an invalid testcase with -fipa-pta (it gets optimized too far,
the stack frame is elided).
