----------------
@rjmccall I would like to push a new value for __FLT_EVAL_METHOD__ at the start
of the scope of this pragma, then pop that value of the macro to restore the
previous setting when the scope is exited, should I do that in ParsePragma? Can
I do that by injecting "pragma push_macro(...)" into the token stream, do you
have other suggestion or is there something similar in clang that I can study
how to do this?
