[Bug middle-end/44450] New: gcc.dg/lto/20090210 fails with emutls

[ro at gcc dot gnu dot org]

I've recently compared testsuite results on Solaris 11/x86 with --enable-tls
(the default) and --disable-tls before going on to investigate TLS problems on
Solaris 8 and 9, especially given that emutls has been broken on mainline (and
the
4.5 branch) for quite some time.

In doing so, I noticed an LTO testcase that fails with --disable-tls, but
passes
without:

+FAIL: gcc.dg/lto/20090210 c_lto_20090210_0.o-c_lto_20090210_1.o link, -O0
-fwhopr
+UNRESOLVED: gcc.dg/lto/20090210 c_lto_20090210_0.o-c_lto_20090210_1.o execute
-O0 -fwhopr

ld: fatal: symbol `__emutls_v.value.1595.2037' is multiply-defined:



+FAIL: gcc.dg/lto/20090210 c_lto_20090210_0.o-c_lto_20090210_1.o link, -O2
-fwhopr
+UNRESOLVED: gcc.dg/lto/20090210 c_lto_20090210_0.o-c_lto_20090210_1.o execute
-O2 -fwhopr

  likewise, just -O2
