From 5bcac8580df6fc62323136f756a3a6d1e754fe9c Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Sat, 24 Nov 2018 04:25:30 +0100 Subject: spirv: remove --spirv-compiler=nvidia This option has been deprecated upstream for a long time, probably doesn't even work anymore, and won't work moving forwards as we replace the vulkan code by libplacebo wrappers. I haven't removed the option completely yet since in theory we could still add support for e.g. a native glslang wrapper in the future. But most likely the future of this code is deletion. As an aside, fix an issue where the man page didn't mention d3d11. --- DOCS/interface-changes.rst | 3 +++ DOCS/man/options.rst | 13 +++++----- video/out/gpu/spirv.c | 8 ------ video/out/vulkan/spirv_nvidia.c | 54 ----------------------------------------- wscript | 3 ++- wscript_build.py | 1 - 6 files changed, 12 insertions(+), 70 deletions(-) delete mode 100644 video/out/vulkan/spirv_nvidia.c diff --git a/DOCS/interface-changes.rst b/DOCS/interface-changes.rst index 26f39beba7..cbc9af18f8 100644 --- a/DOCS/interface-changes.rst +++ b/DOCS/interface-changes.rst @@ -44,6 +44,9 @@ Interface changes `--linear-downscaling`.
