[cfe-dev] Is empty LLVM_TARGETS_TO_BUILD legal?

[Yuri Gribov]

Hi all,

Today I have tried building Clang on Windows with
LLVM_TARGETS_TO_BUILD set to "" (I only need Clang AST so I do not
want to build any backend at all). I called cmake like

  cmake -G "Visual Studio 9 2008" -DLLVM_TARGETS_TO_BUILD="" .

and it got stuck in an endless loop after saying
-- Loadable modules not supported on this platform.

Is this expected behavior? If not - how can we fix it?

Best regards,
Yuri
