Subject: [Bug middle-end/43419] gcc replaces pow(x, 0.5) by sqrt(x), invalid when x is -0
Date: Thu, 18 Mar 2010 14:49:00 -0000 [thread overview]
Message-ID: <20100318144855.32357.qmail@sourceware.org> (raw)
In-Reply-To: <bug-43419-6373@http.gcc.gnu.org/bugzilla/>
------- Comment #4 from matz at gcc dot gnu dot org 2010-03-18 14:48 -------
I checked, and these and similar transformations are always guarded by
flag_unsafe_math_optimizations, so we should be fine, unless I missed a case
of course. If you notice one, please create a bug report.
