--- Comment #6 from Andi Kleen <andi-gcc at firstfloor dot org> --- Created attachment 58761 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58761&action=edit Improve test suite tail call checks This patch should fix it. We must run the test suite tail call probes without optimization to match the actual tests. Also I generalized the general powerpc checks to a new external_tail_call target probe.
