Subject: gallium: need to all draw_flush() in softpipe_unmap_constant_buffers()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=78302c7ca30d27ef3d087deb4d1a22e83858ce4b;p=mesa.git

gallium: need to all draw_flush() in softpipe_unmap_constant_buffers()

Otherwise, we won't have our constants when we run the fragment shader.
Fixes crash in glsl tests when SP_VBUF=1.
