If you have a label in assembly code, and you want to use it in
assembly code, then you need to write whatever is appropriate for your
assembly language (e.g., "mov #MyLabel,r0").  That is not really a
compiler issue.

If you have a label in assembly code, and you want to use it in C code
(e.g., by doing "goto MyLabel;"), then, sorry, you can't do that.
