------------------------------------------------------------------
Update on this.
On linux it seems to be sufficient to build LLVM with:
{code}
-DCMAKE_CXX_FLAGS=-fvisibility=hidden -DCLANG_TOOL_LIBCLANG_BUILD=OFF
{code}
on macOS this is not the case. So far we managed to get the wanted result by
hacking:
{code}
set_target_properties(${LIB_NAME}_shared PROPERTIES LINK_FLAGS
-Wl,-unexported_symbol,_LLVMEnablePrettyStackTrace)
{code}
into {{cmake_modules/BuildUtils.cmake}}. This is of course not an acceptable
solution because it hides only the symbol we check for, not all of them. Any
better ideas?

> [C++] Gandiva exposes LLVM symbols

> Key: ARROW-7241
> URL: https://issues.apache.org/jira/browse/ARROW-7241
> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Giulio Eulisse
> Priority: Major
>
> Despite the fact the cmake seems to indicate the opposite, I see that gandiva
> on macOS is compiled with LLVM symbols exported. E.g.:
> {code}
> nm ../sw/osx_x86-64/arrow/latest/lib/libgandiva.dylib | grep
> _LLVMEnablePrettyStackTrace
> 000000000120b5a0 T _LLVMEnablePrettyStackTrace
> {code}
> is that expected?
