Actually r11 is the static chain regnum and r12 is the temporary
reg to which the port switched. I just tried manually changing the
assembly code produced by GCC around profiling calls to save r11 as well,
but it had no effect. I even saved both r11 and r12, but that had no
effect. When profiling, applications using the GCC nested function
extension fail. I do not think that static chain is the problem.
