Subject: java-tree.h (struct lang_type): Change type to a VEC.
X-Git-Tag: upstream/12.2.0~91927
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9062f848ce87430efb0218a97068cbf3f2d9f214;p=platform%2Fupstream%2Fgcc.git

java-tree.h (struct lang_type): Change type to a VEC.

	* java-tree.h (struct lang_type) [catch_classes]: Change type to a
	VEC.
	* except.c (prepare_eh_table_type): Call CONSTRUCTOR_APPEND_ELT
	instead of tree_cons.
	* class.c (make_class): Add dummy entry to TYPE_CATCH_CLASSES.
	(emit_catch_table): Adjust for new type of TYPE_CATCH_CLASSES.
