Author: Pierre-Eric Pelloux-Prayer <[email protected]> Date: Mon May 17 15:52:49 2021 +0200 radeonsi: enable glsl_correct_derivatives_after_discard by default Enabling this option by default allows the nir_opt_move_discards_to_top to be used more often. This is only done for LLVM13+ since doing this on LLVM11 hurts a lot of shaders.
