X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dd517ad96d1ca53ba8912c8d6fd78b89e6948f23;p=mesa.git ac/nir: fix lds store for patch outputs. This wasn't calculating the correct value, this along with a nir patch fixes a regression in: dEQP-VK.tessellation.shader_input_output.barrier Fixes: 043d14db30a (ac/nir: don't write tcs outputs to LDS that aren't read back.)
