From b102b014375abd1272940ba8bcdbf60878a60649 Mon Sep 17 00:00:00 2001 From: Christophe Lyon Date: Wed, 11 Jan 2023 09:40:21 +0000 Subject: arm: [MVE intrinsics] add unspec_mve_function_exact_insn_vshl Introduce a function that will be used to build vshl intrinsics. They are special because they have to handle MODE_r. 2022-09-08 Christophe Lyon gcc/ * config/arm/arm-mve-builtins-functions.h (class unspec_mve_function_exact_insn_vshl): New. --- gcc/config/arm/arm-mve-builtins-functions.h | 150 ++++++++++++++++++++++++++++ 1 file changed, 150 insertions(+) diff --git a/gcc/config/arm/arm-mve-builtins-functions.h b/gcc/config/arm/arm-mve-builtins-functions.h index 5abf913..533fd11 100644 --- a/gcc/config/arm/arm-mve-builtins-functions.h +++ b/gcc/config/arm/arm-mve-builtins-functions.h @@ -376,6 +376,156 @@ public: } }; +/* Map the function directly to CODE (UNSPEC, M) for vshl-like + builtins.
