Isn't this note now not relevant for this target?

[^x86_32-floats-x87]

RalfJung · 2025-02-10T18:38:00Z

Ah right that should have been changed to x86_32-floats-return-ABI. I'll submit a follow-up PR.

Internal Changes ---------------- These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Build the rustc on AArch64 Linux with ThinLTO + PGO.] (rust-lang/rust#133807) The ARM 64-bit compiler (AArch64) on Linux is now optimized with ThinLTO and PGO, similar to the optimizations we have already performed for the x86-64 compiler on Linux. This should make it up to 30% faster.
