From 68a4c796d52cfcb19830525d904d0ce87d154275 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Sat, 13 Jul 2019 12:06:00 -0500 Subject: [PATCH] intel/fs: Properly stride NULL replacement regs in DCE This fixes some validation errors generated by certain D->W conversions but is likely not a full solution. Calculating an actual register stride is a far more complex problem in general and should probably be handled by the brw_fs_generator.
