Revision 56fb2d6eb63acd48b50437b415b6f7d2fcffe75d authored by Josh Poimboeuf on 26 October 2016, 15:34:08 UTC, committed by Ingo Molnar on 27 October 2016, 06:20:27 UTC
The following commit:
3732710ff6f2 ("objtool: Improve rare switch jump table pattern detection")
... improved objtool's ability to detect GCC switch statement jump
tables for GCC 6. However the check to allow short jumps with the
scanned range of instructions wasn't quite right. The pattern detection
should allow jumps to the indirect jump instruction itself.
This fixes the following warning:
drivers/infiniband/sw/rxe/rxe_comp.o: warning: objtool: rxe_completer()+0x315: sibling call from callable instruction with changed frame pointer
