Subject: [Bug target/7285] [ia64] unsigned-to-floating conversion not spec conformant
Date: Fri, 17 Dec 2004 14:30:00 -0000 [thread overview]
Message-ID: <20041217142851.28402.qmail@sourceware.org> (raw)

------- Additional Comments From jbeulich at novell dot com 2004-12-17 14:28 -------
Now that I have an Itanium2 system to test with, I can confirm that the problem
still exists in 3.4.3, and looking at the delta to 4.0.0's ia64.md there is no
reason to believe the problem would have been fixed there.
fnorm.d.s0 (as example, I tested with double) does set ar.fpsr.sf0.d, and thus
would raise an exception if that was unmasked, and even if it's masked may
confuse subsequent code in making it incorrectly assume some floating point
operation happened on denormal input(s).
