             Bug #: 50654
           Summary: Many Go tests fail on emutls targets
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: ian@airs.com
        ReportedBy: ro@gcc.gnu.org
              Host: *-*-solaris2.[89]
            Target: *-*-solaris2.[89]
             Build: *-*-solaris2.[89]


Between 20110930 and 20111006, many Go tests started to FAIL on Solaris 8 and
9/x86 (haven't tried SPARC yet) with Sun as, thus they use emutls:

output is:
Undefined            first referenced

 symbol                  in file

__emutls_v.__go_panic_defer        
/var/gcc/regression/trunk/8-gcc/build/i386-pc-solaris2.8/./libgo/.libs/libgo.so

__emutls_v.m                       
/var/gcc/regression/trunk/8-gcc/build/i386-pc-solaris2.8/./libgo/.libs/libgo.so

ld: fatal: Symbol referencing errors. No output written to
/var/gcc/regression/trunk/8-gcc/build/gcc/testsuite/go/array-1.x

collect2: error: ld returned 1 exit status


FAIL: go.go-torture/execute/array-1.go compilation,  -O0 

With gas and native TLS, the tests work fine.
