This patch adds a concept of internal functions that map directly to an optab (here called "direct internal functions"). The function can only be used if the associated optab can be used. We currently have four functions like that: - LOAD_LANES - STORE_LANES - MASK_LOAD - MASK_STORE so the patch converts them to the new infrastructure. These four all need different types of optabs, but future patches will add regular unary and binary ones. In general we need one or two modes to decide whether an optab is supported, depending on whether it's a convert_optab or not. This in turn means that we need up to two types to decide whether an internal function is supported. The patch records which types are needed for each internal function, using -1 if the return type should be used and N>=0 if the type of argument N should be used. (LOAD_LANES and STORE_LANES are unusual in that both optab modes come from the same array type.) Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * coretypes.h (tree_pair): New type. * internal-fn.def (DEF_INTERNAL_OPTAB_FN): New macro. Use it for MASK_LOAD, LOAD_LANES, MASK_STORE and STORE_LANES. * internal-fn.h (direct_internal_fn_info): New structure. (direct_internal_fn_array): Declare. (direct_internal_fn_p, direct_internal_fn): New functions. (direct_internal_fn_types, direct_internal_fn_supported_p): Declare. * internal-fn.c (not_direct, mask_load_direct, load_lanes_direct) (mask_store_direct, store_lanes_direct): New macros. (direct_internal_fn_array) New array. (get_multi_vector_move): Return the optab handler without asserting that it is available. (expand_LOAD_LANES): Rename to... (expand_load_lanes_optab_fn): ...this and add an optab argument. (expand_STORE_LANES): Rename to... (expand_store_lanes_optab_fn): ...this and add an optab argument. (expand_MASK_LOAD): Rename to... (expand_mask_load_optab_fn): ...this and add an optab argument. (expand_MASK_STORE): Rename to... (expand_mask_store_optab_fn): ...this and add an optab argument. (direct_internal_fn_types, direct_optab_supported_p) (multi_vector_optab_supported_p, direct_internal_fn_supported_p) (direct_internal_fn_supported_p): New functions. (direct_mask_load_optab_supported_p): New macro. (direct_load_lanes_optab_supported_p): Likewise. (direct_mask_store_optab_supported_p): Likewise. (direct_store_lanes_optab_supported_p): Likewise.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. 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*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
