Set some fast math attributes in setFunctionAttributes (details)
Set some fast math attributes in setFunctionAttributes This will provide a more consistent view to codegen for these attributes. The current system is somewhat awkward, and the fields in TargetOptions are reset based on the command line flag if the attribute isn't set. By forcing these attributes with the flag, there can never be an inconsistency in the behavior if code directly inspects the attribute on the function without considering the command line flags.
