------- Comment #25 from jv244 at cam dot ac dot uk 2008-12-16 16:17 -------
doing some more profiling, the -O0 problem is to a large extend due to
compute_inline_parameters and estimate_stack_frame_size. Spending 10-30min just
on estimating the stack_frame_size on something that can't be reasonably
inlined anyways seems a waste.
