Several existing internal functions map directly to an instruction defined in target-insns.def. This patch makes it easier to define more such functions in future. This should help to reduce cut-&-paste, but more importantly, it allows the difference between optab functions and target-insns.def functions to be abstracted away; both are now treated as “directly-mapped”. gcc/ * internal-fn.def (DEF_INTERNAL_INSN_FN): New macro. (GOMP_SIMT_ENTER_ALLOC, GOMP_SIMT_EXIT, GOMP_SIMT_LANE) (GOMP_SIMT_LAST_LANE, GOMP_SIMT_ORDERED_PRED, GOMP_SIMT_VOTE_ANY) (GOMP_SIMT_XCHG_BFLY, GOMP_SIMT_XCHG_IDX): Use it. * internal-fn.h (direct_internal_fn_info::directly_mapped): New member variable. (direct_internal_fn_info::vectorizable): Reduce to 1 bit. (direct_internal_fn_p): Also return true for internal functions that map directly to instructions defined target-insns.def. (direct_internal_fn): Adjust comment accordingly. * internal-fn.cc (direct_insn, optab1, optab2, vectorizable_optab1) (vectorizable_optab2): New local macros. (not_direct): Initialize directly_mapped. (mask_load_direct, load_lanes_direct, mask_load_lanes_direct) (gather_load_direct, len_load_direct, mask_store_direct) (store_lanes_direct, mask_store_lanes_direct, vec_cond_mask_direct) (vec_cond_direct, scatter_store_direct, len_store_direct) (vec_set_direct, unary_direct, binary_direct, ternary_direct) (cond_unary_direct, cond_binary_direct, cond_ternary_direct) (while_direct, fold_extract_direct, fold_left_direct) (mask_fold_left_direct, check_ptrs_direct): Use the macros above. (expand_GOMP_SIMT_ENTER_ALLOC, expand_GOMP_SIMT_EXIT): Delete (expand_GOMP_SIMT_LANE, expand_GOMP_SIMT_LAST_LANE): Likewise; (expand_GOMP_SIMT_ORDERED_PRED, expand_GOMP_SIMT_VOTE_ANY): Likewise. (expand_GOMP_SIMT_XCHG_BFLY, expand_GOMP_SIMT_XCHG_IDX): Likewise. (direct_internal_fn_types): Handle functions that map to instructions defined in target-insns.def. (direct_internal_fn_types): Likewise. (direct_internal_fn_supported_p): Likewise. (internal_fn_expanders): Likewise. |

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.
