NIR Continues Successfully Serving The Needs Of Mesa, Better Suited Than LLVM
Prominent Mesa developer Jason Ekstrand who formerly led Intel's "ANV" Vulkan driver effort and being one of their open-source driver developers originally involved with the NIR intermediate representation work wrote a detailed and excellent blog post outlining its successes eight years running. While it still gets brought up into discussions from time to time (including quite recently stemming from a RISC-V graphics thread) why Mesa doesn't use LLVM IR or SPIR-V directly as its intermediate representation, NIR continues as a striking success and used by all major Mesa drivers...
