--- Comment #5 from Vincent Lef=C3=A8vre <vincent-gcc at vinc17 dot net> ---
(In reply to Andrew Pinski from comment #4)
> A regression since GCC 3.2 (r0-47863-g881b2a9652748ad).

Always reproducible with GCC 5. But with GCC 4.7 to 4.9, it seems that one
needs -O1 to get fldpi generated. I can't reproduce the bug with GCC 4.1.2 =
to
4.6.4 on godbolt (even with -O3).=
