It miscompiles
if (need <= i) {
in filterstring inlined to builtin_filter in Python/bltinmodule.c.
Testcase:
int __attribute__((noinline))
foo (long i, long j)
{
if (i >= 1)
if (j > -9223372036854775807L)
{
long x;
j--;
x = i + j;
if (x >= 0)
return 1;
}
return 0;
}
int main()
{
if (foo (1, 1) != 1)
abort ();
return 0;
}
