From 7ad7ae1fac53b9f5743eb55808a0d39f63295dff Mon Sep 17 00:00:00 2001 From: Chris Bieneman Date: Thu, 10 Sep 2015 18:22:33 +0000 Subject: [PATCH] [CMake] Add lto subdirectory explicitly. This is required because ExternalProject_Add requires all targets specified in the DEPENDS argument must exist before calling ExternalProject_Add. I have a follow-up patch to clang that enables using the just-built libLTO in bootstrap builds, so we need to be able to add the LTO target as a dependency in clang. llvm-svn: 247316 --- llvm/tools/CMakeLists.txt | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/llvm/tools/CMakeLists.txt b/llvm/tools/CMakeLists.txt index 2031693..aca4350 100644 --- a/llvm/tools/CMakeLists.txt +++ b/llvm/tools/CMakeLists.txt @@ -30,6 +30,10 @@ if(CYGWIN OR NOT LLVM_ENABLE_PIC) set(LLVM_TOOL_LLVM_LTO_BUILD Off) endif() +# Add LTO before clang, ExternalProject requires targets specified in DEPENDS +# to exist before the call to ExternalProject_Add +add_llvm_tool_subdirectory(lto) + # Projects supported via LLVM_EXTERNAL_*_SOURCE_DIR need to be explicitly # specified. add_llvm_external_project(clang) -- 2.7.4
