Subject: vbo: Declare the index range invalid for DrawIndirect
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=df6ec2aba52be66423c90c3f00c599cb2eba4558;p=mesa.git

vbo: Declare the index range invalid for DrawIndirect

Right now, we're just setting the range to [0, MAX_UINT32] which, while
correct isn't helpful.  With DrawIndirect, you can't really know what the
actual range is so we may as well flag it as being an invalid range.  This
is what we do for draws with index buffer which is similar (the indices
aren't statically known) if a bit simpler.
