==== NIR ====

NIR (New Internal Representation) was introduced to overcome TGSI limitations.<ref>{{Cite web|url=https://people.freedesktop.org/~cwabbott0/nir-docs/intro.html|title = Introduction — NIR 0.0.1 documentation}}</ref><ref>{{Cite web|url=http://www.jlekstrand.net/jason/projects/mesa/nir-notes/|title = NIR: A new compiler IR for Mesa}}</ref> NIR was extended in last and actual releases as base of Spir-V support and is since 2016 main development area. LLVMpipe, i965, RadeonSI, Nouveau, freedreno, vc4 are changed to NIR from TGSI. RADV, Zink and other new drivers starts with NIR. All drivers with full OpenGL 4.6 support are related to NIR by SPIR-V support. Also AMD r600 has a fork with NIR for better support of HD5000 and HD6000 series. This option for r600 is default since Mesa 21.0.
