From f3e507ef9f75dbfc58ccd07b5fe8cfca10d9a9e3 Mon Sep 17 00:00:00 2001 From: Brian Date: Thu, 1 Feb 2007 09:51:48 -0700 Subject: New SWspanarrays attribs[] array. Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups. --- src/mesa/swrast/s_aatritemp.h | 39 ++++++++++++++++++++------------------- 1 file changed, 20 insertions(+), 19 deletions(-) (limited to 'src/mesa/swrast/s_aatritemp.h') diff --git a/src/mesa/swrast/s_aatritemp.h b/src/mesa/swrast/s_aatritemp.h index b5470a02980..3359a919e5c 100644 --- a/src/mesa/swrast/s_aatritemp.h +++ b/src/mesa/swrast/s_aatritemp.h @@ -289,7 +289,7 @@ array->z[count] = (GLuint) solve_plane(cx, cy, zPlane);
