[Mesa-dev] [PATCH v2 1/7] nv50/ir: add nv50_ir_prog_info_out

Mark Menzynski mmenzyns at redhat.com
Fri Feb 21 12:19:56 UTC 2020


From: Karol Herbst <kherbst at redhat.com>

Split out the output relevant fields from the nv50_ir_prog_info struct
in order to have a cleaner separation between the input and output of
the compilation.
