<div>
<pre>Currently it is not possible to use no_sanitize("coverage") to disable coverage
instrumentation.
This came up in the context of constraints for certain Linux kernel functions:
<a href="https://lkml.kernel.org/r/CANpmjNPNa2f=kAF6c199oYVJ0iSyirQRGxeOBLxa9PmakSXRbA@mail.gmail.com">https://lkml.kernel.org/r/CANpmjNPNa2f=kAF6c199oYVJ0iSyirQRGxeOBLxa9PmakSXRbA@mail.gmail.com</a>
-- The current workaround on x86 is to turn calls to __sanitizer_cov_* into
nops, however, for other architectures no such support is implemented but will
be required eventually.</pre>
