Macro std::intrinsics::mir::mir

pub macro mir(
        $(type RET = $ret_ty:ty;)? $(let $local_decl:ident $(:
        $local_decl_ty:ty)?;)* $(debug $dbg_name:ident => $dbg_data:expr;)* {
        $($entry:tt)* } $($block_name:ident = { $($block:tt)* })*
    ) {
    ...
}

Macro for generating custom MIR.

See the module documentation for syntax details. This macro is not magic - it only transforms your MIR into something that is easier to parse in the compiler.
