Hi, I just came across an optimization issue in pass peephole2: Regs that are "naturally" dead because the function ends are not marked as dead, and therefore some optimization opportunities pass by unnoticed, e.g. together with recog.c::peep2_reg_dead_p() et. al.
As I could not find a related PR, is this worth opening one? Regards, G.Lay Ah, I am using version 4.5.1
