I did not realize hwasan was not mentioned in RequiresPIE before.
Could you add a test for it?

Don't replace existing tests!
Add new ones.

I am not replacing them, I am making it consistent with all other sanitizers, which also support many more platforms than just x86_64-linux-gnu or *-unknown-linux, but have tests for that one platform only.

• Add tests to verify that HWASan requires "-pie".

I don't think this is a good argument for changing existing tests. It does not add any new coverage, and in this particular example it is not even consistent with surrounding RUN lines - those use i386 triple. It simply adds noise to code history.

If you want to test that hwasan supports x86_64 triple - add a new test case.

Ok, this file, I'm ambivalent about, it is not consistent already, but the other ones I do feel quite strongly about, they are become more consistent and consistency is good.

[eugenis]

OK, sure, If you feel so strongly about this.

Hi, I'm curious about why hwasan requires PIE. Is there any documents mentioned this? Thanks!
