New Revision: 240531
URL: http://svn.freebsd.org/changeset/base/240531

Log:
  Pull in r163967 from upstream llvm trunk:
  
    X86: Emitting x87 fsin/fcos for sinf/cosf is not safe without unsafe
    fp math.
  
  This should make clang emit calls to libm for sinf/cosf by default.
  
  MFC after:	1 week
