[PATCH] PPC linuxthreads tls.h fix
- From: Steven Munroe <sjmunroe at us dot ibm dot com>
- To: libc-alpha <libc-alpha at sources dot redhat dot com>, Franz-Sirl <Franz-Sirl at lauterbach dot com>

- Subject: [PATCH] PPC linuxthreads tls.h fix
- Organization: IBM Linux Developement
- Reply-to: sjmunroe at vnet dot ibm dot com
The PPC32/PPC64 TLS ABIs specify that the tcb is exactly 8/16 bytes and
that the first word/doubleword of the tcb is the dtv pointer. Similar to
Alpha.
