Revision b9f07eb2f25a64098e2ba223c1a2fe2a8f249e01 authored by Wu Zhangjin on 21 January 2011, 18:01:53 UTC, committed by Ralf Baechle on 14 March 2011, 20:07:24 UTC
trace.func should be set to the recorded ip of the mcount calling site in the __mcount_loc section to filter the function entries configured through the tracing/set_graph_function interface, but before, this is set to the self_ra(the return address of mcount), which has made set_graph_function not work as expected. This fixes it via calculating the right recorded ip in the __mcount_loc section and assign it to trace.func.
