Package: llvm-10-toolchain
Severity: important

Hi,

The final release did not help getting mesa built, and now that I tried to 
migrate
the Intel OpenCL stack I bumped into the same bug:

/usr/bin/ld: /usr/lib/llvm-10/lib/libclangCodeGen.a(BackendUtil.cpp.o): in 
function `(anonymous 
namespace)::EmitAssemblyHelper::EmitAssemblyWithNewPassManager(clang::BackendAction,
 std::unique_ptr<llvm::raw_pwrite_stream, 
std::default_delete<llvm::raw_pwrite_stream> >)':
