Description
With recent jump threading opt improvements, the JIT is able to remove most branches for the following code, but there's still some leftover can be cleanup:
class Program
{
void Test(int x)
{
if (x > 1)
{
if (x > 2)
{
if (x > 3)
{
if (x > 4)
{
Console.WriteLine(1);
}
}
}
}
}
}Codegen:
Program:Test(int):this (FullOpts):
push rbp
mov rbp, rsp
cmp esi, 2 ; <-- redundant branch
