Subject: mesa: Fold error generation into _mesa_valid_prim_mode().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7ca4f07b5b77ccac0a9b60dc5ac9082906b5947e;p=mesa.git

mesa: Fold error generation into _mesa_valid_prim_mode().

We want to start emitting an INVALID_OPERATION from here for transform
feedback.  Note that this forced dlist.c to almost not use this
function, since it wants different behavior during dlist compile.
Just pull the non-TF, non-GS test out for compile, because:

1) TF doesn't matter in that case because there's no drawing.
2) I don't think we're going to see GSes and display lists in the same
   context, if we don't do GL_ARB_compatibility.
