[llvm-dev] Go Tsan check failure

Tue Nov 28 00:47:17 PST 2017

Hi,
I want to build clang successfully :) I don't care about Go.

buildgo.sh is invoked directly by ninja. I don't want to modify the
(generated) build.ninja

The "SILENT=1" is hard-coded into build.ninja and ninja -v has no effect on it.

I tried passing  -DLLVM_INCLUDE_GO_TESTS=OFF to cmake but the result
was the same.
