From: "rguenth at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/30038] Call to sin(x), cos(x) should be transformed to sincos(x) Date: Thu, 07 Dec 2006 20:50:00 -0000 [thread overview] Message-ID: <20061207205021.31047.qmail@sourceware.org> (raw) In-Reply-To: <bug-30038-13404@http.gcc.gnu.org/bugzilla/> ------- Comment #15 from rguenth at gcc dot gnu dot org 2006-12-07 20:50 ------- Note that for _vectorization_ of sincos we need the following: - a vectorized sincos implementation and vectorization support for it (that's the easier part). At the moment we only can vectorize calls to sqrt. - re-order the recip pass (tree-ssa-math-opts.c) and the loop passes. At the moment we generate the sincos _after_ vectorization -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30038
