--- Comment #4 from Launchpad  ---
Arnd Bergmann added the following comment to Launchpad bug report 1296942:

Looks good now, I have resumed ARM kernel build testing with gcc-4.9 now and
don't see this any more. There is one new bug that came up instead but it seems
unrelated. I'll open a new ticket for that.

--- Comment #1 from Jakub Jelinek  ---
Supposedly introduced by r203160 which made inline asm with no input operands
appear as having zero cost.
