Subject: S390: Clobber also r14 in TLS_LD, TLS_GD macros on 31bit.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch also clobbers r14 in TLS_LD, TLS_GD macros on 31bit.
This ensures that r14 isn't used to save and restore r12 while
r14 is clobbered by the bas-instruction.

As note:
r12 can't be added to clobber list as gcc would fail with:
error: PIC register clobbered by ‘12’ in ‘asm’

For 64bit this fix was already done in 2004 in the
commit b80af23ac6973e69df6cd23d221fa44fffb21e17.

ChangeLog:

	* sysdeps/s390/s390-32/tls-macros.h (TLS_LD, TLS_GD):
	Clobber also r14.
