From: Jordan Justen Date: Sat, 4 Nov 2017 23:53:15 +0000 (-0700) Subject: i965: Add ARB_get_program_binary support using nir_serialization X-Git-Tag: upstream/18.1.0~3344 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b4c37ce2140c0195005d865b7a4de903ef50a097;p=platform%2Fupstream%2Fmesa.git i965: Add ARB_get_program_binary support using nir_serialization This resolves an apparent game bug described in 85564. The game doesn't properly handle ARB_get_program_binary with 0 supported formats. V2 (Timothy Arceri): - less driver code as more has been moved into the common helpers.
