[LLVMdev] Shared libs build failing since yesterday

[Renato Golin]

Hi,

I have a debug build with shared libraries (to reduce compilation
time), but since yesterday, it's failing with an ExecutionEngine
error:

FAILED: : && /usr/lib/ccache/bin/c++  -fPIC -fPIC
-fvisibility-inlines-hidden -Wall -W -Wno-unused-parameter

undefined reference to `llvm::setFunctionAttributes(llvm::StringRef,
llvm::StringRef, llvm::TargetOptions const&, llvm::Module&, bool)'
collect2: error: ld returned 1 exit status

This is my CMake command line:

cmake -G Ninja $LLVM_SRC -DCMAKE_BUILD_TYPE=Debug
-DLLVM_BUILD_TESTS=False -DLLVM_INCLUDE_EXAMPLES=False
-DLLVM_ENABLE_ASSERTIONS=True -DBUILD_SHARED_LIBS=True
-DLLVM_TARGETS_TO_BUILD="ARM;X86;AArch64"
-DPYTHON_EXECUTABLE=/usr/bin/python2

Static object compilation is unaffected.

Any ideas?

cheers,
