761c8352f494 [svn r235] rough port of GDC's inline assembler code, unfinished ChristianK parents: diff changeset	168 1) Reference the label with a reachable goto statement
761c8352f494 [svn r235] rough port of GDC's inline assembler code, unfinished ChristianK parents: diff changeset	169 2) Have reachable computed goto in the function
