The following code (reduced example) triggers an ICE with a recent `master`
(96e4244ef3ccf4867ca4e37fbc6800e64ef30af6).
$ cat test.ii
extern "C" double sqrt(double);
double a, b, c;
void d() {
for (;;) {
c = __builtin_fabs(a);
sqrt(c);
if (a)
a = b;
}
}
$ /home/aland/gcc-trunk/bin/g++ -O2 -c test.ii
