From: Timothy Arceri Date: Sat, 16 Dec 2017 03:06:23 +0000 (+1100) Subject: compiler: tidy up double_inputs_read uses X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f63e05ae9ea0be38a8fb2dd0ae8f391b8699e757;p=mesa.git compiler: tidy up double_inputs_read uses First we move double_inputs_read into a vs struct in the union, double_inputs_read is only used for vs inputs so this will save space and also allows us to add a new double_inputs field. We add the new field because c2acf97fcc9b changed the behaviour of double_inputs_read, and while it's no longer used to track actual reads in i965 we do still want to track this for gallium drivers.
