From 27ced5c5ff907557007ed6cb78cef5810cf48ef5 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 14 Oct 2010 14:33:30 -0700 Subject: glsl: Add support for the 1.30 round() built-in. This implements round() via the ir_unop_round_even opcode, rather than adding a new opcode. We may wish to add one in the future, since it might enable a small performance increase on some hardware, but for now, this should suffice. --- src/glsl/builtins/ir/round | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 src/glsl/builtins/ir/round (limited to 'src/glsl/builtins/ir/round') diff --git a/src/glsl/builtins/ir/round b/src/glsl/builtins/ir/round new file mode 100644 index 0000000000..d0d425bd65 --- /dev/null +++ b/src/glsl/builtins/ir/round @@ -0,0 +1,21 @@ +((function round + (signature float + (parameters + (declare (in) float arg0)) + ((return (expression float round_even (var_ref arg0))))) + + (signature vec2 + (parameters + (declare (in) vec2 arg0)) + ((return (expression vec2 round_even (var_ref arg0))))) + + (signature vec3 + (parameters + (declare (in) vec3 arg0)) + ((return (expression vec3 round_even (var_ref arg0))))) + + (signature vec4 + (parameters + (declare (in) vec4 arg0)) + ((return (expression vec4 round_even (var_ref arg0))))) +)) -- cgit v1.2.3
