As PR110248 shows, to get the expected query results for
that internal functions LEN_{LOAD,STORE} is able to adopt
some addressing modes, we need to pass down the related
IFN code as well. This patch is to make IVOPTs pass down
ifn code for USE_PTR_ADDRESS type uses, it adjusts the
related functions {strict_,}memory_address_addr_space_p,
and valid_mem_ref_p as well.
PR tree-optimization/110248
gcc/ChangeLog:
* recog.cc (memory_address_addr_space_p): Add one more argument ch of
type code_helper and pass it to targetm.addr_space.legitimate_address_p
instead of ERROR_MARK.
(offsettable_address_addr_space_p): Update one function pointer with
one more argument of type code_helper as its assignees
memory_address_addr_space_p and strict_memory_address_addr_space_p
have been adjusted, and adjust some call sites with ERROR_MARK.
* recog.h (tree.h): New include header file for tree_code ERROR_MARK.
(memory_address_addr_space_p): Adjust with one more unnamed argument
of type code_helper with default ERROR_MARK.
(strict_memory_address_addr_space_p): Likewise.
* reload.cc (strict_memory_address_addr_space_p): Add one unnamed
argument of type code_helper.
* tree-ssa-address.cc (valid_mem_ref_p): Add one more argument ch of
type code_helper and pass it to memory_address_addr_space_p.
* tree-ssa-address.h (valid_mem_ref_p): Adjust the declaration with
one more unnamed argument of type code_helper with default value
ERROR_MARK.
* tree-ssa-loop-ivopts.cc (get_address_cost): Use ERROR_MARK as code
by default, change it with ifn code for USE_PTR_ADDRESS type use, and
pass it to all valid_mem_ref_p calls.

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
