Subject: [Bug optimization/15135] program hangs in call to sqrt when compiled with -O
Date: Sun, 25 Apr 2004 19:57:00 -0000 [thread overview]
Message-ID: <20040425173413.1845.qmail@sources.redhat.com> (raw)
In-Reply-To: <20040425165245.15135.dfg@decode.is>
------- Additional Comments From pinskia at gcc dot gnu dot org 2004-04-25 17:34 -------
A simpler testcase for 3.4.0 and above:
inline double fmax(double a, double b) {
return (a<=b)? b : a;
}
double f() {
return __builtin_sqrt(__builtin_nan("")/fmax(1., 1./.0));
}
int main() {
double u = f();
return 0;
}
Confirmed.
