From: Richard Sandiford Date: Thu, 12 Jul 2018 13:02:17 +0000 (+0000) Subject: Implement SLP of internal functions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5249ee4d79855edda91b26bb07c9c8737cdfc96c;p=gcc.git Implement SLP of internal functions SLP of calls was previously restricted to built-in functions. This patch extends it to internal functions. 2018-07-12 Richard Sandiford gcc/ * internal-fn.h (vectorizable_internal_fn_p): New function. * tree-vect-slp.c (compatible_calls_p): Likewise. (vect_build_slp_tree_1): Remove nops argument. Handle calls to internal functions. (vect_build_slp_tree_2): Update call to vect_build_slp_tree_1. gcc/testsuite/ * gcc.dg/vect/vect-cond-arith-6.c: New test. * gcc.target/aarch64/sve/cond_arith_4.c: Likewise. * gcc.target/aarch64/sve/cond_arith_4_run.c: Likewise. * gcc.target/aarch64/sve/cond_arith_5.c: Likewise. * gcc.target/aarch64/sve/cond_arith_5_run.c: Likewise. * gcc.target/aarch64/sve/slp_14.c: Likewise. * gcc.target/aarch64/sve/slp_14_run.c: Likewise.
