Subject: Re: [PATCH] Set discriminators for call stmts on the same line within the same basic block
Date: Mon, 10 Oct 2022 20:54:05 -0400	[thread overview]
Message-ID: <CAGWvny=e-=ho1eZTq6s5tJVXTvLFbBJzL7pmUfPGEsODbdpKGQ@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 655 bytes --]

This patch causes a bootstrap comparison failure on AIX.  It apparently
does not cause a failure on PPC64BE Linux with the same ABI, so I suspect
that the failure may be related to the way that function aliases are
implemented on AIX, which doesn't have ELF symbol alias semantics.

"This change will also simplify call site lookups since now location with
discriminator will uniquely identify the call site (no callee function name
is needed)."

I will open a PR with more information about the comparison difference now
that I have a work-around to bring AIX back to a bootstrappable state.  Any
thoughts about what could be going wrong?

Thanks, David
