Subject: Aligning tcmalloc with glibc 2.35 rseq ABI
Date: Tue, 1 Feb 2022 09:58:16 -0500 (EST)	[thread overview]
Message-ID: <432231420.24682.1643727496135.JavaMail.zimbra@efficios.com> (raw)

Hi Chris,

You will probably want to have a look at the userspace rseq ABI exposed by glibc 2.35 to ensure
tcmalloc becomes compatible with it.

If it helps, you can have a look at how I modified librseq to play nicely with glibc 2.35:

Most relevant bits:

Thanks,

Mathieu
