Subject: freedreno/ir3/ra: drop extending output live-ranges
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf0aa7ed90231540c66328a515928dd8e3324343;p=mesa.git

freedreno/ir3/ra: drop extending output live-ranges

This is no longer needed as we create meta:collect instructions in the
end block, which achieves the same result.
