[llvm-commits] [llvm] r42885 - in /llvm/trunk: include/llvm/Intrinsics.td lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp test/CodeGen/X86/vector-intrinsics.ll

New Revision: 42885

URL: http://llvm.org/viewvc/llvm-project?rev=42885&view=rev
Log:
Add intrinsics for sin, cos, and pow. These use llvm_anyfloat_ty, and so
may be overloaded with vector types. And add a testcase for codegen for
these.
