From: Caio Marcelo de Oliveira Filho Date: Tue, 3 Mar 2020 18:19:15 +0000 (-0800) Subject: anv: Use a dynamic array for storing executables in pipeline X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9bf044d2541e1612419ff2ba41758e71a6fd9a9c;p=mesa.git anv: Use a dynamic array for storing executables in pipeline Avoids waste for pipelines that don't use all the shaders, and is flexible enough to cover cases where there are multiple variants per shader (e.g. SIMD8/16/32 for fragment shader). Even though we could pre-calculate the exact size of the array, this is not a critical path so it is worth preventing the bug that will likely happen when new variants are added but not accounted for.
