| H A D | decode.c | b490f453 Fri Apr 24 09:30:42 CDT 2020 Miroslav Benes <mbenes@suse.cz> objtool: Move the IRET hack into the arch decoder
Quoting Julien:
"And the other suggestion is my other email was that you don't even
need to add INSN_EXCEPTION_RETURN. You can keep IRET as
INSN_CONTEXT_SWITCH by default and x86 decoder lookups the symbol
conaining an iret. If it's a function symbol, it can just set the type
to INSN_OTHER so that it caries on to the next instruction after
having handled the stack_op."
