From cfe33c46aa50f04adb0431243e7d25f79b719ac6 Mon Sep 17 00:00:00 2001 From: David Greene Date: Wed, 26 Jan 2011 19:13:22 +0000 Subject: [AVX] Add INSERT_SUBVECTOR and support it on x86. This provides a default implementation for x86, going through the stack in a similr fashion to how the codegen implements BUILD_VECTOR. Eventually this will get matched to VINSERTF128 if AVX is available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124307 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/ISDOpcodes.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'include/llvm/CodeGen/ISDOpcodes.h') diff --git a/include/llvm/CodeGen/ISDOpcodes.h b/include/llvm/CodeGen/ISDOpcodes.h index ac3d87c4bd..c7edb12097 100644 --- a/include/llvm/CodeGen/ISDOpcodes.h +++ b/include/llvm/CodeGen/ISDOpcodes.h @@ -269,6 +269,14 @@ namespace ISD { /// lengths of the input vectors.
