From ce461ffc5aa2ea6941d6722e8ed473cda8c17833 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 3 Apr 2009 12:49:03 -0600 Subject: mesa: only clear matrix MAT_DIRTY_INVERSE flag when we actually compute the inverse If _math_matrix_analyse() got called before we allocated the inverse matrix array we could lose the flag indicating that we needed to compute the inverse. This could happen with certain vertex shader cases. --- src/mesa/math/m_matrix.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'src/mesa/math') diff --git a/src/mesa/math/m_matrix.c b/src/mesa/math/m_matrix.c index 58cae88b08..da6956efed 100644 --- a/src/mesa/math/m_matrix.c +++ b/src/mesa/math/m_matrix.c @@ -1379,11 +1379,10 @@ _math_matrix_analyse( GLmatrix *mat ) if (mat->inv && (mat->flags & MAT_DIRTY_INVERSE)) { matrix_invert( mat ); + mat->flags &= ~MAT_DIRTY_INVERSE; } - mat->flags &= ~(MAT_DIRTY_FLAGS| - MAT_DIRTY_TYPE| - MAT_DIRTY_INVERSE); + mat->flags &= ~(MAT_DIRTY_FLAGS | MAT_DIRTY_TYPE); } /*@}*/ -- cgit v1.2.3
