Signed-off-by: Giovanni Mascellani gmascellani@codeweavers.com --- Though I think you forgot to split the switch cases with newlines in fold_mul().
Also, I wouldn't dislike a small comment saying that we're handling signed integers together with unsigned integers to avoid undefined behavior. It's not necessarily obvious for anybody reading the code.

v3: Resent with some minor modifications: avoid initializers after statements; add line breaks between switch cases; simplify trace messages; make function names into proper verbs.
I don't hold strong opinions one way or another on whether this should live in a separate file.
