Correct bisection result is: 8d8222461f9d7f497d657c2c0eff70820986429b is the first bad commit commit 8d8222461f9d7f497d657c2c0eff70820986429b Author: Jason Ekstrand <jason.ekstrand@intel.com> Date: Mon Jul 23 22:20:41 2018 -0700 intel/nir: Enable nir_opt_find_array_copies Potential fix: https://gitlab.freedesktop.org/mesa/mesa/merge_requests/1802 Should be fixed with: 2bfcf043456411a6037404d9afae9760964c9b48 Author: Sergii Romantsov <sergii.romantsov@globallogic.com> Date: Thu Aug 29 10:58:38 2019 +0300 nir/large_constants: pass after lowering copy_deref v2: by J.Ekstrand suggestion moved lowering of large constants after lowering of copy_deref is done. CC: Jason Ekstrand <jason@jlekstrand.net> CC: Caio Marcelo de Oliveira Filho <caio.oliveira@intel.com> Reviewed-by: Jason Ekstrand <jason@jlekstrand.net> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111450 Signed-off-by: Sergii Romantsov <sergii.romantsov@globallogic.com> I think the commit is missing a fixes or CC tag, since it fixes a blocker for mesa 19.2. |
