Subject: [Bug tree-optimization/57994] Constant folding of infinity
Date: Sat, 27 Jul 2013 20:26:00 -0000	[thread overview]
Message-ID: <bug-57994-4-cuTBG2Q8vW@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #8 from Paolo Carlini <paolo.carlini at oracle dot com> ---
About sin(Inf): I checked that with / without the real_isfinite the expression
evaluated in every case the same, -nan, if I remember correctly. I don't have
more details at the moment. My general point, again, is that the mpfr testsuite
appears to include test which check that +-inf are correctly handled as
arguments to the mathematical functions. Which, hey, doesn't seem a miracle,
after all ;) Remember, I'm thinking as a start, no-nan, no-complex.
