From 9ac6a9b2fa45debac63f2e2b20d78c4776d06e37 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 27 Dec 2010 00:22:38 -0800 Subject: glsl: Support if-flattening beyond a given maximum nesting depth. This adds a new optional max_depth parameter (defaulting to 0) to lower_if_to_cond_assign, and makes the pass only flatten if-statements nested deeper than that. By default, all if-statements will be flattened, just like before. This patch also renames do_if_to_cond_assign to lower_if_to_cond_assign, to match the new naming conventions. --- src/glsl/ir_optimization.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/glsl/ir_optimization.h') diff --git a/src/glsl/ir_optimization.h b/src/glsl/ir_optimization.h index f264265f4b..dbc9f4ab97 100644 --- a/src/glsl/ir_optimization.h +++ b/src/glsl/ir_optimization.h @@ -53,7 +53,7 @@ bool do_lower_jumps(exec_list *instructions, bool pull_out_jumps = true, bool lo bool do_lower_texture_projection(exec_list *instructions); bool do_if_simplification(exec_list *instructions); bool do_discard_simplification(exec_list *instructions); -bool do_if_to_cond_assign(exec_list *instructions); +bool lower_if_to_cond_assign(exec_list *instructions, unsigned max_depth = 0); bool do_mat_op_to_vec(exec_list *instructions); bool do_mod_to_fract(exec_list *instructions); bool do_noop_swizzle(exec_list *instructions); -- cgit v1.2.3
