Subject: call.c (initialize_reference): Add flags parm.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e495f6b0c06db941cd213941fe659127eedb13b1;p=gcc.git

call.c (initialize_reference): Add flags parm.

	* call.c (initialize_reference): Add flags parm.
	* decl.c (grok_reference_init): Likewise.
	(check_initializer): Pass it.
	* typeck.c (convert_for_initialization): Likewise.
	* cp-tree.h: Adjust.
