From 11b923c99cbe3580885ce40c322277fc823107a0 Mon Sep 17 00:00:00 2001
From: Naveen Saini <naveen.kumar.saini@intel.com>
Date: Tue, 2 Feb 2021 13:39:53 +0800
Subject: [PATCH] IGC/VectorCompiler/CMakeLists.txt: link to external
LLVMGenXIntrinsics
By default LLVMGenXIntrinsics is to be build In-tree, but we want to
link externally.
Fix llvm-tblgen path.
Upstream-Status: Inappropriate [configuration specific]
