Subject: ivopts: Handle vector with length IFNs
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ead2be56f0e1d60ffcc519efb33c1ca7b78c23ba;p=gcc.git

ivopts: Handle vector with length IFNs

This patch is to handle vector with length internal functions
IFN_LEN_LOAD and IFN_LEN_STORE in IVOPTS.

gcc/ChangeLog:

	* tree-ssa-loop-ivopts.c (get_mem_type_for_internal_fn): Handle
	IFN_LEN_LOAD and IFN_LEN_STORE.
	(get_alias_ptr_type_for_ptr_address): Likewise.
