From 23262fb8a08d6dc0f1d4f0665f6f8731ee7cf710 Mon Sep 17 00:00:00 2001 From: Quentin Colombet Date: Thu, 16 Jan 2014 06:43:55 +0000 Subject: [cmake] Attempt to fix sanitizer buildbot. The generation of the native_export_file end up in several different makefiles. All those makefiles write the same file, but can be executed concurrently... and bad things happen! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199356 91177308-0d34-0410-b5e6-96231b3b80d8 --- cmake/modules/AddLLVM.cmake | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'cmake') diff --git a/cmake/modules/AddLLVM.cmake b/cmake/modules/AddLLVM.cmake index de00ab46ae..e93ea10089 100644 --- a/cmake/modules/AddLLVM.cmake +++ b/cmake/modules/AddLLVM.cmake @@ -85,8 +85,12 @@ function(add_llvm_symbol_exports target_name export_file) # Force re-linking when the exports file changes.
