Subject: Re: [PATCH] aix: ensure reference to __tls_get_addr is in text section.
Date: Thu, 14 Oct 2021 09:42:48 -0400	[thread overview]
Message-ID: <CAGWvnykb+7RtZkbu1v3_DN+z=-_TPER64JS7oVVyBEFtF_OexA@mail.gmail.com> (raw)
In-Reply-To: <PA4PR02MB6686AB43F30EF47E591F12E0EAB89@PA4PR02MB6686.eurprd02.prod.outlook.com>

The reference to __tls_get_addr is in the data section.  And the code
just above creates a symbol in the text section referenced from the
data section to ensure the text section is retained.  So this change
doesn't make sense.  You're essentially saying that the data section
is not used, which makes the other code useless to ensure that the
text section is referenced.

Thanks, David
