From b8bf97b7e127f0ff4bff7adb8e15536e108d3696 Mon Sep 17 00:00:00 2001 From: Chris Bieneman Date: Tue, 10 Mar 2015 20:48:02 +0000 Subject: [PATCH] Add new LLVM_OPTIMIZED_TABLEGEN build setting which configures, builds and uses a release tablegen build when LLVM is configured with assertions enabled. Summary: This change leverages the cross-compiling functionality in the build system to build a release tablegen executable for use during the build.
