Subject: i965/vs: Generalize data structures pointed to by vec4_generator.
X-Git-Tag: mesa-9.2.1~1825
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9bb6840b28a9a77377d437198c62d705cade5370;p=platform%2Fupstream%2Fmesa.git

i965/vs: Generalize data structures pointed to by vec4_generator.

This patch removes the following field from vec4_generator, since it
is not used:

- struct brw_vs_compile *c

And changes the following field:

- struct gl_vertex_program *vp => struct gl_program *prog

With these changes, vec4_generator no longer refers to any VS-specific
data structures.  This will pave the way for re-using it for geometry
shaders.

v2: Use the name "prog" rather than "p".
