Disable some tests for platforms without registers. Update new tests to run on aarch64 platforms. 2021-09-06 15:44:19 +00:00			`//@ needs-asm-support`

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. 2021-12-10 00:15:33 +00:00			`use std::arch::asm;`
