Subject: ir_visit_tree: Make sure we visit dereference targets, too.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dc1dbd65e1099d98a05302e4ee67bc84c59a1386;p=mesa.git

ir_visit_tree: Make sure we visit dereference targets, too.

Found this with the local dead code pass, which never saw variable
dereferences occurring.
