From 69be9934a780eadc7c0b64465fae8431eb979dae Mon Sep 17 00:00:00 2001 From: "Juan A. Suarez Romero" Date: Tue, 12 Feb 2019 08:54:43 +0000 Subject: nir: move ALU instruction before the jump instruction opt_split_alu_of_phi moves ALU instruction to the end of continue block. But if the continue block ends with a jump instruction (an explicit "continue" instruction) then the ALU must be inserted before the jump, as it is illegal to add instructions after the jump.
