From 9e895831bcb35b0a14f68538376b15ae4e94ae0d Mon Sep 17 00:00:00 2001 From: Michal Krol Date: Wed, 27 Jan 2010 20:43:42 +0100 Subject: [PATCH] tgsi: Constants declared with ureg_DECL_constant() are one-dimensional. This is to maintain backward compatibility with drivers that don't support arrays of constant buffers. --- src/gallium/auxiliary/tgsi/tgsi_ureg.c | 26 ++++++++++++++++++++++---- 1 file changed, 22 insertions(+), 4 deletions(-) diff --git a/src/gallium/auxiliary/tgsi/tgsi_ureg.c b/src/gallium/auxiliary/tgsi/tgsi_ureg.c index d207097984b..f2610d07644 100644 --- a/src/gallium/auxiliary/tgsi/tgsi_ureg.c +++ b/src/gallium/auxiliary/tgsi/tgsi_ureg.c @@ -136,7 +136,8 @@ struct ureg_program unsigned temps_active[UREG_MAX_TEMP / 32]; unsigned nr_temps; - struct const_decl const_decls[PIPE_MAX_CONSTANT_BUFFERS]; + struct const_decl const_decls; + struct const_decl const_decls2D[PIPE_MAX_CONSTANT_BUFFERS]; unsigned property_gs_input_prim; unsigned property_gs_output_prim; @@ -371,6 +372,9 @@ out: /* Returns a new constant register.
