[Bug tree-optimization/37312] -Os significantly faster than -O2 on test case



------- Comment #2 from rguenth at gcc dot gnu dot org  2008-09-01 13:42 -------
Uh, well.  The code ist mostly inline assembly which doesn't give GCC much
freedom to do something.  I guess -O2 simply optimizes "too much" around the
asm.  Try not using inline assembly instead.
