           Summary: Several UCN tests FAIL on Tru64 UNIX V5.1B and IRIX
                    6.5
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ro@gcc.gnu.org
              Host: alpha-dec-osf5.1b, mips-sgi-irix6.5
            Target: alpha-dec-osf5.1b, mips-sgi-irix6.5
             Build: alpha-dec-osf5.1b, mips-sgi-irix6.5


Several UCN tests partially fail on Tru64 UNIX V5.1B and IRIX 6.5. One common
example is

FAIL: gcc.dg/ucnid-10.c  (test for warnings, line 7)
FAIL: gcc.dg/ucnid-10.c  (test for warnings, line 8)
FAIL: gcc.dg/ucnid-10.c (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/ucnid-10.c:7:9: warning:
#pragma pack(pop, ó) encountered without matching #pragma pack(push, ó)
[-Wpragmas]
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/ucnid-10.c:8:9: warning:
unknown action 'ç' for '#pragma pack' - ignored [-Wpragmas]

Instead of being printed in \u... notation, the characters are printed
literally.

The set of failures isn't identical on both platforms (maybe due to char being
unsigned on IRIX, but signed on Tru64 UNIX?), but the symptom is always the
same.

This would be a testsuite issue; the tests require a locale using the 
ASCII character set.  Where (in several .exp files) the code does

# Many hosts now default to a non-ASCII C locale, however, so
# they can set a charset encoding here if they need.
if { [ishost "*-*-cygwin*"] } {
  setenv LC_ALL C.ASCII
  setenv LANG C.ASCII
}

or similar, you need to add a new case for your targets using an 
appropriate locale name - if they have a version of the C locale that uses 
ASCII.

From my reading of libiconv 1.13.1 libcharset/tools/{irix-6.5,
osf1-5.1}, it seems that there isn't any such locale.  If this cannot be
helped, it seems that we should have some

    dg-require-effective-target ascii-locale

(suggestions for a better name welcome) to disable the affected tests on
platforms like this.

Joseph, did you see that comment?  The mail may not have gone out during
the Bugzilla/Perl snafu on gcc.gnu.org.

Anyway, on second thought this is a host, not a target issue, so this
should be something like dg-require-ascii-locale instead.
