macro_rules! dynasm {
($a:expr_2021 ; $($tt:tt)*) => { ... };
}Expand description
Force dynasm! to use the correct arch (x64) when cross-compiling.
dynasm! proc-macro tries to auto-detect it by default by looking at the
target_arch, but it sees the target_arch of the proc-macro itself, which
is always equal to host, even when cross-compiling.
