Subject: gallivm: Remove bogus assert.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=45f174ce40c8eab006e8f032ffc40703050a639b;p=mesa.git

gallivm: Remove bogus assert.

It is perfectly valid for the swizzle to be bigger than 2. For example the
texel offsets could be

  SAMPLE ..., IMM[0].zzz

What is not correct is for chan_index to be bigger than 2.

Trivial.
