| H A D | error-inject.c | 7cd01b08 Thu Jun 07 04:52:02 CDT 2018 Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com> powerpc: Add support for function error injection
We implement regs_set_return_value() and override_function_with_return()
for this purpose.
On powerpc, a return from a function (blr) just branches to the location
contained in the link register. So, we can just update pt_regs rather
than redirecting execution to a dummy function that returns.
