Subject: broadcom/vc5: Lower unpack_*_4x8 to normal math.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=125f2a751e0062077504f3651840e71d58c88af2;p=mesa.git

broadcom/vc5: Lower unpack_*_4x8 to normal math.

We only have 2x16 unpacking in our ALUs.  To enable this, we also need
lower_fdiv for its new instructions, which had been handled at a higher
level previously.
