           Summary: libstdc++ testsuite failures when using -pipe
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: allan@archlinux.org


When building gcc with "-pipe" in the C{XX}FLAGS, the following test suite
failures occur:

FAIL: 20_util/enable_shared_from_this/cons/constexpr.cc (test for excess
errors)
FAIL: 20_util/shared_ptr/cons/constexpr.cc (test for excess errors)
FAIL: 20_util/unique_ptr/cons/constexpr.cc (test for excess errors)
FAIL: 20_util/weak_ptr/cons/constexpr.cc (test for excess errors)
FAIL: 30_threads/future/cons/constexpr.cc (test for excess errors)
FAIL: 30_threads/shared_future/cons/constexpr.cc (test for excess errors)

This is because the following warning gets outputed:
g++: warning: -pipe ignored because -save-temps specified

Those tests have to use -save-temps to inspect the assembler output, I think
the answer is to not use -pipe

Or sed it out of C{XXFLAGS} when determining what flags to pass to the
testsuite.

So, just to clarify...  Is this being seen as something that the person
building the gcc test-suite should deal with or something that should be dealt
with in the test-suite?

It shouldn't happen unless the person running the testsuite specifies it, so
they can not specify it.  How did you configure the library to hit this
problem?

Jakub's suggestion is that the testsuite could filter it out, so that even when
users do specify it, the testsuite doesn't use it.

I know you said with -pipe in your CFLAGS, is that all?  

You could probably edit scripts/testsuite_flags to remove -pipe as a workaround
