The commit of the patch to eliminate race conditions in indirect value
profiling (r157822) hasn't triggered the same profile related testsuite
failures in any other target. This leads to two questions...
1) Does any other target really use emulated tls besides darwin?
2) Is standard tls the same as native tls? In other words, are there really
three forms, (tls, native tls and emulated tls, or just two forms (native) tls
and emulated tls?
I ask because according to...
case ${host} in
i[34567]86-*-linux* | x86_64-*-linux* | \
i[34567]86-*-kfreebsd*-gnu | i[34567]86-*-knetbsd*-gnu | \
i[34567]86-*-gnu*)
tmake_file="${tmake_file} t-tls"
;;
esac
...only those targets are using native tls which would suggest (if there are
only two forms of tls) that targets like powerpc64-*-linux* should be using
emulated tls like darwin and thus be failing the profile testcases now. This
isn't the case.
