[Mesa-dev] [PATCH] radv: include LLVM IR in the VK_AMD_shader_info "disassembly"

[Nicolai Hähnle]

From: Nicolai Hähnle <nicolai.haehnle at amd.com>

Helpful for debugging compiler backend problems: this allows us to
easily retrieve the LLVM IR from RenderDoc.

For the peanut gallery: AMD's official stance on radv hasn't changed.
But we take regressions for radv caused by our changes in LLVM seriously.
After all, they might just as well affect anything else using the same
compiler backend...
