Uros' patch for PR22576 indeed fixes the ICEs in redirect_branch
and extract_insn on the 4.0 branch and mainline.
But I can now confirm the bug in expand_simple_unop, I just had to
add -march=i486 to the command line. So here's a reduced testcase
(compile with "gcc -O -ffast-math -march=i486"):
====================================
int foo(long double d, int i)
{
if (d == (long double)i)
return 1;
}
====================================
Happens on the 4.0 branch and mainline.
