— runtime: Make Amiga library work with -fbaserel
This currently uses __saveds on all exported functions for simplicity.
As an optimization, __saveds can be removed from some functions later
after careful verification that no code path starting from that function
accesses any data. (user: js, size: 20233) [annotate] [blame] [check-ins using]
