From: Jason Ekstrand Date: Thu, 26 May 2016 00:27:23 +0000 (-0700) Subject: i965: Move brw_create_nir to brw_program.c X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5e43ba7e9e9bfce451f9caa3845136f8a5b6eda0;p=mesa.git i965: Move brw_create_nir to brw_program.c This way it's no longer part of libi965_compiler.la since it depends on GLSL and ARB program stuff.
