From: "jsm28 at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/58684] New: powerpc uses only unordered floating-point compares Date: Thu, 10 Oct 2013 16:34:00 -0000 [thread overview] Message-ID: <bug-58684-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684 Bug ID: 58684 Summary: powerpc uses only unordered floating-point compares Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: jsm28 at gcc dot gnu.org Target: powerpc*-* When compiling for powerpc (classic hard-float), floating-point compares always use the fcmpu instructions that don't raise exceptions for unordered operands, never the exception-raising fcmpo variants. The correct behavior is to raise exceptions for comparisons such as "x < y", but not for "x == y" or "__builtin_isless (x, y)".
