// Make sure rustdoc accepts options(att_syntax) asm! on non-x86 targets.
Stabilize asm! and global_asm! They are also removed from the prelude as per the decision in https://github.com/rust-lang/rust/issues/87228. stdarch and compiler-builtins are updated to work with the new, stable asm! and global_asm! macros.
