           Summary: Many TLS tests fail on Solaris 11/x86 with gold
           Product: binutils
           Version: 2.22 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gold
        AssignedTo: address@hidden
        ReportedBy: address@hidden
              Host: i386-pc-solaris2.11
            Target: i386-pc-solaris2.11
             Build: i386-pc-solaris2.11


Despite the excellent gold testsuite results on Solaris 11/x86, gcc testresults
were terrible.  Most of the failures seem to be due to two issues, though:

Many of the TLS tests fail, particularly (only including -O0):

32-bit:

FAIL: gcc.dg/torture/tls/run-ie.c  -O0  execution test
FAIL: gcc.dg/torture/tls/run-le.c  -O0  execution test

64-bit:

FAIL: gcc.dg/torture/tls/run-ie.c  -O0  execution test
FAIL: gcc.dg/torture/tls/run-ld.c  -O0  execution test
FAIL: gcc.dg/torture/tls/run-le.c  -O0  execution test

My strong suspicion is that gold needs fixes along the lines of

Properly align static TLS segments on Solaris 2
http://sourceware.org/ml/binutils/2010-09/msg00485.html
http://sourceware.org/ml/binutils/2010-10/msg00291.html

and
