Subject: i965/eu: Make it clear that brw_find_loop_end only runs on Gen6+.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0457464c3343b3809048249fa5c1c0867ef499dc;p=mesa.git

i965/eu: Make it clear that brw_find_loop_end only runs on Gen6+.

It has Gen6+ knowledge baked in, and indeed is only called for Gen6+,
but it wasn't immediately obvious that this was the case.
