I'm not, but I've found this:
https://github.com/Amanieu/rfcs/blob/inline-asm/text/0000-inline-asm.md#asm-goto
seems to me, the plan for this is something like below:
asm!(
"cmp {}, 42",
"jeq {}",
in(reg) val,
label { println!("a"); },
fallthrough { println!("b"); }
);
But it's not implemented yet. Cc Josh in case that he knows more about
this.
