--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
This has been broken right from the initial implementation of plt branch stubs.
A quick fix is to use r11 in the stub when calling the save/restore functions,
safe because out-of-line save isn't used in nested functions where r11 holds
the static chain. I'll implement that first, then look at emitting multiple
copies of the save/restore functions.
