From 974b1907178f980063d4b4defefe3eb4d3d50b7b Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Thu, 18 Oct 2012 20:25:36 +0000 Subject: [PATCH] Use an export list when building JIT unittests. When building with LTO, the internalize pass is hiding some global symbols that are necessary for the JIT unittests. It seems like that may be a bug in LTO to do that by default, but until that gets fixed, this change makes sure that we export the necessary symbols for the tests to pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166220 91177308-0d34-0410-b5e6-96231b3b80d8 --- unittests/ExecutionEngine/JIT/Makefile | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/unittests/ExecutionEngine/JIT/Makefile b/unittests/ExecutionEngine/JIT/Makefile index b535a6b2960..9e0bb9ea593 100644 --- a/unittests/ExecutionEngine/JIT/Makefile +++ b/unittests/ExecutionEngine/JIT/Makefile @@ -35,8 +35,15 @@ ifeq ($(USE_OPROFILE), 1) LINK_COMPONENTS += oprofilejit endif +EXPORTED_SYMBOL_FILE = $(PROJ_OBJ_DIR)/JITTests.exports include $(LLVM_SRC_ROOT)/unittests/Makefile.unittest # Permit these tests to use the JIT's symbolic lookup.
