you are using indirect function calls here, GCC in 4.6 is not smart enough
to transform them to direct calls before inlining. Inlining of
always-inline indirect function calls is not going to work reliably.
Don't use always-inline or don't use indirect function calls to always-inline
functions. It makes always-inline function calls survive until IPA inlining
where we seem to honor limits even though we say we should disregard them.
Honza?
Considering pd_combine_conjoint_xor with 383 size
to be inlined into combine_conjoint_xor_ca_float in t.i:53
Estimated growth after inlined into all callees is +748 insns.
Estimated badness is -2147483648, frequency 1.00.

Inlined into combine_conjoint_xor_ca_float which now has time 1402 and size
