- Subject: RFC: Some expect cleanups for the threads tests
These patches fix some testsuite problems on my setup - compiler and
assembler both support TLS, but the C library doesn't. I think you get a
different error (earlier) if the kernel doesn't support TLS; I'll have to
check at some point.
Elena, how do the two TLS changes look? The print-threads.exp just handles
the case where we weren't switching threads before reporting the SIGTRAP, so
the zombie notice was never printed. If you say "info threads" at that
point GDB crashes. I'll get that one later today.

* gdb.threads/print-threads.exp (test_all_threads): Loosen KFAIL
pattern.
* gdb.threads/tls-shared.exp: Don't use gdb_suppress_entire_file.
* gdb.threads/tls.exp: Recognize one case of the host library not
supporting TLS.
