This is how perf reports the dynamically generated code emitted by llvm.

That the percentages fall off so quickly is a little suspicious. To me
that reads as though gnome-shell itself is being starved for work to do
and that other things are actually taking more time. Is this perf trace
from the whole system or just of gnome-shell?

I used 'perf record -p 6425' to attach gnome-shell, so that's all it
should be. FYI - This is F17-Alpha-i686-Live-Desktop installed to a USB
HDD on the i845G box.
