Subject: [PATCH 15/19] use the same data type for tls_array.
Date: Wed, 12 Dec 2007 10:54:00 -0200 [thread overview]
Message-ID: <1197464139284-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <11974641314148-git-send-email-gcosta@redhat.com>
This patch changes the type of tls_array in x86_64 to
a desc_struct. Now, both i386 and x86_64 tls_array have
the same type, and code accessing it can be shared.
