Hi Steven: You are right, I have build arm toolchain today, it's crash when building libgcc since there is no valid CFG in split_all_insns_noflow. Hi Jeff: Maybe we need split_reg_dead_p and split_reg_unused_p like peephole2 have peep2_reg_dead_p?
Seems pretty reasonable.I'm still curious which of the 4 passes of split_all_insns was triggering the failure though,
