[llvm-dev] Testing LLVM XRay

[buddhika chamith via llvm-dev]

Hi All,

I am trying to test run clang XRay tool. I was following the steps at [1].
But the log file does not seem to get generated. According to the
instructions I used 'fxray-instrument' switch when compiling and then
specified 'patch_premain=true' at XRAY_OPTIONS. Is there anything else that
I need to do? I am on a trunk build of clang. Could that be it? I am on
clang version 8.0.0 (trunk 340502).

Regards
Buddhika
