--- Comment #1 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-09-30 10:19:00 UTC ---
The decision is reasonable (I suppose partial inlining will inline the
if (!init) case) as the function is called exactly once then and thus
should be optimized for size and put into a separate section.

The question is thus, why does that break IA64 bootstrap?

If IA64 doesn't support .text.unlikely it should define
UNLIKELY_EXECUTED_TEXT_SECTION_NAME appropriately.
