From: Paul Berry Date: Tue, 2 Apr 2013 16:35:32 +0000 (-0700) Subject: Revert "glsl: Replace constant-index vector array accesses with swizzles" X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2ad0ed63497f27b77be49cb04a6dc9df21fe75f2;p=mesa.git Revert "glsl: Replace constant-index vector array accesses with swizzles" This reverts commit dbf94d105a48b7aafb2c8cf64d8b4392d87efea1, which was working around a bug in the handling of array indexing when constant folding built-in functions. Now that the constant folding bug has been fixed, the workaround is no longer needed. --- diff --git a/src/glsl/builtins/glsl/determinant.glsl b/src/glsl/builtins/glsl/determinant.glsl index 0800d40cff7..84f38725e16 100644 --- a/src/glsl/builtins/glsl/determinant.glsl +++ b/src/glsl/builtins/glsl/determinant.glsl @@ -28,44 +28,44 @@ float dot(vec4, vec4);
