From 9e699cc72639f25b20e73f51ab06ab7a0884ea62 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Fri, 7 Aug 2009 23:53:05 +0000 Subject: [PATCH] Add new intrinsics for Neon VTRN, VZIP and VUZP operations. Modeling these as vector shuffles did not work out well. Shuffles that produce double-wide vectors accurately represent the operation but make it hard to do anything with the results. I considered splitting them up into 2 shuffles, one to write each register separately, but there doesn't seem to be a good way to reunite them for codegen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78437 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/IntrinsicsARM.td | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/include/llvm/IntrinsicsARM.td b/include/llvm/IntrinsicsARM.td index efe5bff4371..e9a7e2e91da 100644 --- a/include/llvm/IntrinsicsARM.td +++ b/include/llvm/IntrinsicsARM.td @@ -66,6 +66,12 @@ let TargetPrefix = "arm" in { // All intrinsics start with "llvm.arm.".
