I think the change above only affects the static but not component build, which
defines a shared 'gpu' library here with everything and would not use O2 anymore
after your change.

[Nico, 2014/09/16 17:42:39]

Does that matter? The component build can't be used for perf testing anyhoo,
right?

[pasko, 2014/09/16 17:50:47]

+1, I would say it is WAI, since component_build == fastbuild, and -O2 makes the
build slower.

Done.
