From 4e16a7b526bb4736cd11e512009cf6532b2d1dc5 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 30 Jun 2010 15:59:07 -0700 Subject: glsl2: Fix up the implementation of fract() for vector types. There's no need to split each vector component out, just do vector ops. --- src/glsl/builtins/110/fract | 18 +++--------------- 1 file changed, 3 insertions(+), 15 deletions(-) (limited to 'src/glsl/builtins/110/fract') diff --git a/src/glsl/builtins/110/fract b/src/glsl/builtins/110/fract index 3995bfaf3f9..46741bb3cb4 100644 --- a/src/glsl/builtins/110/fract +++ b/src/glsl/builtins/110/fract @@ -7,28 +7,16 @@ (signature vec2 (parameters (declare (in) vec2 x)) - ((declare () vec2 t) - (assign (constant bool (1)) (swiz x (var_ref t)) (expression float - (swiz x (var_ref x)) (expression float floor (swiz x (var_ref x))))) - (assign (constant bool (1)) (swiz y (var_ref t)) (expression float - (swiz y (var_ref x)) (expression float floor (swiz y (var_ref x))))) - (return (var_ref t)))) + ((return (expression vec2 - (var_ref x) (expression vec2 floor (var_ref x)))))) (signature vec3 (parameters (declare (in) vec3 x)) - ((declare () vec3 t) - (assign (constant bool (1)) (swiz x (var_ref t)) (expression float - (swiz x (var_ref x)) (expression float floor (swiz x (var_ref x))))) - (assign (constant bool (1)) (swiz y (var_ref t)) (expression float - (swiz y (var_ref x)) (expression float floor (swiz y (var_ref x))))) - (assign (constant bool (1)) (swiz z (var_ref t)) (expression float - (swiz z (var_ref x)) (expression float floor (swiz z (var_ref x))))) - (return (var_ref t)))) + ((return (expression vec3 - (var_ref x) (expression vec3 floor (var_ref x)))))) (signature vec4 (parameters (declare (in) vec4 x)) - ((declare () vec4 t) - (assign (constant bool (1)) (swiz x (var_ref t)) (expression float - (swiz x (var_ref x)) (expression float floor (swiz x (var_ref x))))) - (assign (constant bool (1)) (swiz y (var_ref t)) (expression float - (swiz y (var_ref x)) (expression float floor (swiz y (var_ref x))))) - (assign (constant bool (1)) (swiz z (var_ref t)) (expression float - (swiz z (var_ref x)) (expression float floor (swiz z (var_ref x))))) - (assign (constant bool (1)) (swiz w (var_ref t)) (expression float - (swiz w (var_ref x)) (expression float floor (swiz w (var_ref x))))) - (return (var_ref t)))) + ((return (expression vec4 - (var_ref x) (expression vec4 floor (var_ref x)))))) )) -- cgit v1.2.3
