Yes but I think we really should mask ALL exceptions regardless of denorms. A shader might easily do things causing exceptions (divide by zero or whatnot) and there's certainly no signaled exceptions in 3d graphics. I think we've just not seen issues because they are masked by default and no app unmasked them. Might be worth adding a piglit test for that. -- You are receiving this mail because: You are the assignee for the bug.
