"the intrinsics in compiler_built..." <- > <@9names:matrix.org> the intrinsics in compiler_builtins are linked in such a way that if you define these in your project (or in a crate that your project uses) you can override the default impls. > see https://github.com/rust-lang/compiler-builtins/pull/452 for details. > > rp2040-hal uses this to use the hand-optimised library functions that live in the RP2040 mask ROM (which also saves hitting the QSPI interface). Sounds really cool! Can you provide links at files where it's used? I'm curious
