Codegen tests for -Z instrument-xray Let's add at least some tests to verify that this option is accepted and produces expected LLVM attributes. More tests can be added later with attribute support. 2022-10-02 10:25:49 +09:00			// Checks that `-Z instrument-xray` produces expected instrumentation.

Test XRay only for supported targets Now that the compiler accepts "-Z instrument-xray" option only when targeting one of the supported targets, make sure to not run the codegen tests where the compiler will fail. Like with other compiletests, we don't have access to internals, so simply hardcode a list of supported architectures here. 2022-10-02 12:58:05 +09:00			`// needs-xray`
