------- Comment #16 from kkojima at gcc dot gnu dot org  2010-01-27 12:32 -------
I've got some new libstdc++-v3 testsuite failures with the patch
on my nightly sh4-linux tester:

Running
/exp/ldroot/dodes/ORIG/trunk/libstdc++-v3/testsuite/libstdc++-dg/conformance.exp
...
FAIL: 23_containers/deque/requirements/exception/basic.cc (test for excess
errors)
WARNING: 23_containers/deque/requirements/exception/basic.cc compilation failed
to produce executable
FAIL: 23_containers/deque/requirements/exception/propagation_consistent.cc

WARNING: 23_containers/deque/requirements/exception/propagation_consistent.cc
compilation failed to produce executable
FAIL: 30_threads/packaged_task/members/get_future.cc execution test
FAIL: 30_threads/shared_future/members/get.cc execution test

The first failure is

/tmp/ccl5TCl4.s: Assembler messages:
/tmp/ccl5TCl4.s:43070: Error: undefined symbol `.L3394' in operation

FAIL: 23_containers/deque/requirements/exception/basic.cc (test for excess
errors)

The last 2 failures are resulted with the unaligned accesses.  I saw

Sending SIGBUS to "get_future.exe" due to unaligned access (PC 296554a8 PR
2965549a)
Sending SIGBUS to "get.exe" due to unaligned access (PC 296554a8 PR 2965549a)

on the target machine.
With reverting the first hunk of the patch, these errors go away.
Christian, could you please revert or disable the first hunk
of patches temporarily?  Sorry I didn't catch this earlier.
