Added to the LLVM 23 Git codebase minutes ago is a pull request adding the initial AMDGPU GFX13 target for their next-generation graphics core IP. AMD GFX13 is presumably for RDNA5.
AMD [1]GFX12 is for RDNA4 GPUs and there has also been the GFX12.5 / GFX1250 IP as a possible "RDNA4 refresh" while merged to LLVM Git this morning is an initial GFX13 target.
For now this initial AMDGPU GFX13 target is based on the features of GFX12 and GFX1250. Nothing too exciting but it's a start.
[2]This commit lays out that initial GFX13 target. We'll see how the AMD GFX13 support evolves by the time of the LLVM 23.1 stable release around late August or September.
