Subject: Use gimple_call_fntype rather than gimple_call_fndecl in pass_return_slot::execute
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5b60bb6dc70e7f94f9c9a8d7584981ecf0720641;p=thirdparty%2Fgcc.git

Use gimple_call_fntype rather than gimple_call_fndecl in pass_return_slot::execute

Call with funciton pointer might not able to get the fndecl, but fntype
so use gimple_call_fntype instead of gimple_call_fndecl.

aggregate_value_p can handle fndecl and fntype right (and even CALL_EXPR), so I
think this change is safe.

gcc/ChangeLog:

	* tree-nrv.cc (pass_return_slot::execute): Use
	gimple_call_fntype instead of gimple_call_fndecl.
