From a993df1ee294b861eef4f35fccabeecd05754f2a Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Mon, 28 Oct 2019 02:31:05 -0300 Subject: shader/node: Unpack bindless texture encoding Bindless textures were using u64 to pack the buffer and offset from where they come from. Drop this in favor of separated entries in the struct. Remove the usage of std::set in favor of std::list (it's not std::vector to avoid reference invalidations) for samplers and images. --- src/video_core/shader/decode/texture.cpp | 59 +++++++++++++++++--------------- 1 file changed, 31 insertions(+), 28 deletions(-) (limited to 'src/video_core/shader/decode/texture.cpp') diff --git a/src/video_core/shader/decode/texture.cpp b/src/video_core/shader/decode/texture.cpp index d61e656b7..8d3d962c7 100644 --- a/src/video_core/shader/decode/texture.cpp +++ b/src/video_core/shader/decode/texture.cpp @@ -255,7 +255,7 @@ u32 ShaderIR::DecodeTexture(NodeBlock& bb, u32 pc) { break;
