/* Regression test for a0 register being corrupted in _xt_context_save.
|
|
*
|
|
* The idea in this test is to have a function which recursively calls itself
|
|
* with call4, eventually filling up all the register windows. At that point,
|
|
* it does some lengthy operation. If an interrupt occurs at that point, and
|
|
* corrupts a0 register of one of the windows, this will cause an exception
|
|
* when the recursive function returns.
