Subject: [Bug target/103008] poor inlined builtin_fmod on x86_64
Date: Sat, 30 Oct 2021 20:15:06 +0000	[thread overview]
Message-ID: <bug-103008-4-WopiqsU05c@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #4 from Dave Love <fx at gnu dot org> ---
On further consideration, perhaps this is just a Fortran issue.  I thought
-ffast-math should turn off all the relevant checks to allow reducing mod to
the arithmetic expression, but it probably doesn't.  Also, MAQAO complained
about x87 instructions being generated, but I'm not sure about that either if
it's just for status.  Apologies if this is invalid, and correction welcome.
