[PATCH] D101467: [docs] Add the compiler-rt requirement to the test suite doc

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added a comment.

With XRay basically  unmaintained <https://lists.llvm.org/pipermail/llvm-dev/2021-July/151637.html>, I would love to see the compiler-rt requirement to go away. At least, its availability could be autodetected. That is, if unavailable, one could see that the X-Ray tests are disabled in the cmake output.

Until then I think the note could be helpful.



================
Comment at: llvm/docs/TestSuiteGuide.md:47-48
+`compiler-rt`, otherwise the MicroBenchmarks/XRay microbenchmarks will fail to
+compile. Make sure you add `compiler-rt` to your `LLVM_ENABLE_PROJECTS` cmake
+flag.

----------------
It might be preferable to add it to `LLVM_ENABLE_RUNTIMES` instead.
