Allow ADDR_EXPRs of TARGET_MEM_REFs
This patch allows ADDR_EXPR <TARGET_MEM_REF ...>, which is useful when calling internal functions that take pointers to memory that is conditionally loaded or stored. This is a prerequisite to the following ivopts patch. 2018-01-13 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * expr.c (expand_expr_addr_expr_1): Handle ADDR_EXPRs of TARGET_MEM_REFs. * gimple-expr.h (is_gimple_addressable: Likewise. * gimple-expr.c (is_gimple_address): Likewise. * internal-fn.c (expand_call_mem_ref): New function. (expand_mask_load_optab_fn): Use it. (expand_mask_store_optab_fn): Likewise.
