Description

Radv (the radeon vulkan driver) has for a long time used LLVM as the
shader compiler backend. However, LLVM has a number of issues which
led us to develop an alternative shader compiler that strongly leans
on the shared nir intermediate language. This new compiler is showing
significant gains for compile time as well as runtime performance.

We will talk about our pain points with LLVM and how ACO solves them,
the overall design of ACO as well as the challenges we see and the
plans we have for the future.
