mir-opt/instrument_coverage.rs test needs profiler support

[tesuji]

mir-opt/instrument_coverage.rs test needs profiler support:

rust/src/test/mir-opt/instrument_coverage.rs

Line 5 in 5f6fcad

// needs-profiler-support

However, profiler is disable by default:

rust/config.toml.example

Line 220 in 5f6fcad

#profiler = false

So when the test failed I can't notice it in my machine.

P/S: Does profiler need support from LLVM ? I am using local LLVM if that count.

Triage: If the problem is that it's disabled by default, what's the problem with enabling it in your local config?

[tesuji]

I have no ideal about this issue since then.
I'd close this issue in this case.

Thanks for getting back, let's close as obsolete then.

That test no longer has //@ needs-profiler-suppport, FTR

rust/tests/mir-opt/coverage/instrument_coverage.rs

Line 6 in 3c1e750

//@ compile-flags: -Cinstrument-coverage -Zno-profiler-runtime

thanks to -Zno-profiler-runtime.
