From: Timothy Arceri Date: Thu, 28 May 2020 00:59:28 +0000 (+1000) Subject: nir: add callback to nir_remove_dead_variables() X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=04dbf709edf069bc720d941fab27c53269336bcf;p=mesa.git nir: add callback to nir_remove_dead_variables() This allows us to do API specific checks before removing variable without filling nir_remove_dead_variables() with API specific code. In the following patches we will use this to support the removal of dead uniforms in GLSL.
