Subject: cp-tree.h (lang_decl_base): Rename template_conv_p to unknown_bound_p.
X-Git-Tag: upstream/12.2.0~37247
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=40300fa4545d51bb636d4f3ca4be6d6914cee321;p=platform%2Fupstream%2Fgcc.git

cp-tree.h (lang_decl_base): Rename template_conv_p to unknown_bound_p.

	* cp-tree.h (lang_decl_base): Rename template_conv_p to
	unknown_bound_p.
	(DECL_CONV_FN_P): Don't check NULL DECL_NAME.
	(DECL_CONV_FN_TYPE): FN must be conv op.
	(DECL_TEMPLATE_CONV_FN_P): Delete.
	(VAR_HAD_UNKNOWN_BOUND, SET_VAR_HAD_UNKNOWN_BOUND): Adjust.
	* pt.c (push_template_decl_real): Delete DECL_TEMPLATE_CONV_FN_P
