"Patent leak" lol.

i understand LLVM releases are once in 6 months. so if AMD misses this deadline then the next one is 6 months away. is that correct ?

Yes, that’s correct. LLVM has a roughly 6-month release cycle. If AMD misses contributing or integrating for one release, the next official release opportunity would be about 6 months later. So missing a deadline can introduce a half-year delay for official inclusion.

so the question is what did they hope to achieve in these 6 months of H1-2026

Some testing of hardware ?? why does that need LLVM updates ???

Perfecting drivers? Only I don't think they committed anywhere near the stuff for this, maybe it's just somebody to collect bonus for shipping LLVM enablement on time and budget.

so the target is September 2026 ???

For now this initial AMDGPU GFX13 target is based on the features of GFX12 and GFX1250. Nothing too exciting but it's a start.

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.

That's just normal compiler enablement schedules.
