I can compile gambit 4.1.2 with -fschedule-insns except for the function noted
in PR41164.
On
model name : Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz
with
gcc version 4.5.0 20090803 (experimental) [trunk revision 150373] (GCC)
the times with -fschedule-insns are
(time (direct-fft-recursive-4 a table))
144 ms cpu time (144 user, 0 system)
(time (inverse-fft-recursive-4 a table))
136 ms cpu time (136 user, 0 system)
and the times without -fschedule-insns are
(time (direct-fft-recursive-4 a table))
168 ms cpu time (168 user, 0 system)
(time (inverse-fft-recursive-4 a table))
172 ms cpu time (172 user, 0 system)
That's a pretty big improvement.
