From: Neil Roberts Date: Fri, 17 Jul 2020 07:08:47 +0000 (+0200) Subject: nir/scheduler: Move nir_scheduler to its own header X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=7665398e6c4fa903405d3daefcc93ddb0a37b488 nir/scheduler: Move nir_scheduler to its own header nir_schedule already has a struct for options which makes it more than just a function declaration. Later patches intend to add more structs to complement these options. In order to make the code easier to manage, this moves the nir_scheduler-related parts out of nir.h to their own header.
