test result: FAILED. 1 passed; 3 failed; 535 ignored; 0 measured; 0 filtered out; finished in 102.37ms

Some tests failed in compiletest suite=assembly mode=assembly host=x86_64-unknown-linux-gnu target=x86_64-unknown-linux-gnu
help: ignored 497 up-to-date tests; use `--force-rerun` to prevent this

From what I can gather, the problem is that the compiler optimizes out the function?
It seems that Rust compiles crates as a separate thing so when the final test binary is built, the metadata is gone so the test here doesn't work anymore.

From what I can gather, the problem is that the compiler optimizes out the function?

Not quite. From what I can tell, the key instructions are still present (i.e. if you comment out the .cfi* directive CHECK-NEXTs the test passes for me locally), but it's missing the CFI directives.

E.g. loongarch64 revision (this PR)

cc @rcvalle do you happen to know why the CFI directives might be missing? FWIW, minicore is built as an rlib + -Cpanic=abort and linked to the test crate via --extern minicore=/path/to/libminicore.rlib.
