--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Mon Jan 7 08:49:08 2019 New Revision: 267632 URL: https://gcc.gnu.org/viewcvs?rev=267632&root=gcc&view=rev Log: PR c++/85052 * tree-vect-generic.c: Include insn-config.h and recog.h. (expand_vector_piecewise): Add defaulted ret_type argument, if non-NULL, use that in preference to type for the result type. (expand_vector_parallel): Formatting fix. (do_vec_conversion, do_vec_narrowing_conversion, expand_vector_conversion): New functions. (expand_vector_operations_1): Call expand_vector_conversion for VEC_CONVERT ifn calls. * internal-fn.def (VEC_CONVERT): New internal function. * internal-fn.c (expand_VEC_CONVERT): New function. * fold-const-call.c (fold_const_vec_convert): New function. (fold_const_call): Use it for CFN_VEC_CONVERT. * doc/extend.texi (__builtin_convertvector): Document. c-family/ * c-common.h (enum rid): Add RID_BUILTIN_CONVERTVECTOR. (c_build_vec_convert): Declare. * c-common.c (c_build_vec_convert): New function. c/ * c-parser.c (c_parser_postfix_expression): Parse __builtin_convertvector. cp/ * cp-tree.h (cp_build_vec_convert): Declare. * parser.c (cp_parser_postfix_expression): Parse __builtin_convertvector. * constexpr.c: Include fold-const-call.h. (cxx_eval_internal_function): Handle IFN_VEC_CONVERT. (potential_constant_expression_1): Likewise. * semantics.c (cp_build_vec_convert): New function. * pt.c (tsubst_copy_and_build): Handle CALL_EXPR to IFN_VEC_CONVERT. testsuite/ * c-c++-common/builtin-convertvector-1.c: New test. * c-c++-common/torture/builtin-convertvector-1.c: New test. * g++.dg/ext/builtin-convertvector-1.C: New test. * g++.dg/cpp0x/constexpr-builtin4.C: New test.
