Subject: [Bug math/5997] Very slow execution of sinf function
Date: Sun, 30 Mar 2008 00:10:00 -0000	[thread overview]
Message-ID: <20080330000955.1185.qmail@sourceware.org> (raw)
In-Reply-To: <20080329211738.5997.jvdelisle@gcc.gnu.org>


------- Additional Comments From jvdelisle at gcc dot gnu dot org  2008-03-30 00:09 -------
On a openSUSE 11.0alpha3, x86_64, glibc 2.7 (20071106 system, the sinf() calls
the ../sysdeps/x86_64/fpu/s_sincosf.c:175 FPU function whereas on a Fedora 8
system with glibc 2.7 the ../sysdeps/ieee754/flt-32/s_sinf.c, line 29 software
implementation of sinf is called.

Any suggestions on how to fix this.  We should be using the FPU calls.
