From: "H. J. Lu" <hjl@lucon.org> Date: Mon, 14 Oct 2002 10:16:40 -0700 The problem here is when gcc fills the delay slot with nop, it kills branch relaxation. My request is gcc never fills the delay slot with nop. If gcc can't find any insn to fill, don't emit .set noreorder. Why not work on making gcc fill the delay slot with something suitable if you think the branch relaxer can do better for your testcase? |
