Matthias Krüger 7c3b2e5254 Rollup merge of #140770 - folkertdev:custom-abi, r=tgross35 ... add `extern "custom"` functions tracking issue: rust-lang/rust#140829 previous discussion: https://github.com/rust-lang/rust/issues/140566 In short, an `extern "custom"` function is a function with a custom ABI, that rust does not know about. Therefore, such functions can only be defined with `#[unsafe(naked)]` and `naked_asm!`, or via an `extern "C" { /* ... */ }` block. These functions cannot be called using normal rust syntax: calling them can only be done from inline assembly. The motivation is low-level scenarios where a custom calling convention is used. Currently, we often pick `extern "C"`, but that is a lie because the function does not actually respect the C calling convention. At the moment `"custom"` seems to be the name with the most support. That name is not final, but we need to pick something to actually implement this. r? `@traviscross` cc `@tgross35` try-job: x86_64-apple-2		2025-06-13 05:19:14 +02:00
