Could changes to ifcvt.c (
http://gcc.gnu.org/ml/gcc-patches/2004-07/msg00498.html and
http://gcc.gnu.org/ml/gcc-patches/2004-07/msg00506.html ) be used to
solve PR 15187 ( http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15187 ) ?
Try adding costs for the FP operations in ix86_rtx_costs
(config/i386/i386.c at line 15000 approx) with David's patch applied.
It should be enough.
