I think this is okay.

The documentation for SYM_INNER_LABEL says it for labels inside a SYM function block, is that a problem? This is a function but doesn't have C calling convention, so asm annotation docs say that it should use SYM_CODE_START_LOCAL?
BTW. why don't our _GLOBAL() macros use these SYM annotations? I haven't really looked into them.
Thanks, Nick
