+	* gimple-fold.c (gimple_fold_builtin_memory_op): Fold calls that
+	were initially created for the assignment of a variable-sized
+	object and whose source is now a string constant.
+	* gimple-ssa-store-merging.c (struct merged_store_group): Document
+	STRING_CST for rhs_code field.
+	Add string_concatenation boolean field.
+	(merged_store_group::merged_store_group): Initialize it as well as
+	bit_insertion here.
+	(merged_store_group::do_merge): Set it upon seeing a STRING_CST.
+	Also set bit_insertion here upon seeing a BIT_INSERT_EXPR.
+	(merged_store_group::apply_stores): Clear it for small regions.
+	Do not create a power-of-2-sized buffer if it is still true.
+	And do not set bit_insertion here again.
+	(encode_tree_to_bitpos): Deal with BLKmode for the expression.
+	(merged_store_group::can_be_merged_into): Deal with STRING_CST.
+	(imm_store_chain_info::coalesce_immediate_stores): Set bit_insertion
+	to true after changing MEM_REF stores into BIT_INSERT_EXPR stores.
+	(count_multiple_uses): Return 0 for STRING_CST.
+	(split_group): Do not split the group for a string concatenation.
+	(imm_store_chain_info::output_merged_store): Constify and rename
+	some local variables.  Build an array type as destination type
+	for a string concatenation, as well as a zero mask, and call
+	build_string to build the source.
+	(lhs_valid_for_store_merging_p): Return true for VIEW_CONVERT_EXPR.
+	(pass_store_merging::process_store): Accept STRING_CST on the RHS.
+	* gimple.h (gimple_call_alloca_for_var_p): New accessor function.
