Skip unnecessary components in x64 try builds #142963

Kobzol · 2025-06-24T13:57:39Z

We unnecessarily rebuild wasm-component-ld, llvm-bitcode-linker and Cranelift during the intermediate PGO builds several times times, which is unnecessarily and increases the duration of try builds. This PR also disables some unnecessary dist components.

Question: to double-check, the "fast try build" is where the user never specified an actual job matcher, right?

Yeah, the try builds most often used for perf. runs. The are so slow now :( A few years ago after my optimizations they were barely 1 hour, but now it's 2.5h :( Just BOLT alone takes >1h, it writes 100 GiB of profiles to disk, lol.

Thanks. Feel free to r=me once the try job comes back okay.

Ok, 2h. That's still quite slow, but much better than 2.5 hours before.

Kobzol · 2025-06-25T14:06:09Z

Dang, I skipped too much and it broke perf. We still need to build Cargo.
