Hi,
the testcases elf/tst-tls1-static and elf/tst-tls2-static
are failing on s390 if gcc is configured with --enable-default-pie:
set bar to 1 (LE)
get sum of foo and bar (IE) = 0
bar = 0
The linker reports the following error without aborting:
elf/tst-tls1-static.o(.text+0x80):
invalid instruction for TLS relocation R_390_TLS_LOAD
According to binutils, there are only four valid cases for IE -> LE
transition:
lg %rx,(0,%ry) -> sllg %rx,%ry,0
lg %rx,(%ry,0) -> sllg %rx,%ry,0
lg %rx,(%ry,%r12) -> sllg %rx,%ry,0
lg %rx,(%r12,%ry) -> sllg %rx,%ry,0
Thus I've adjusted the TLS_IE macro in s390 tls-macros.h files in PIC
case in order to use r12 for the address of global offset table.
The adjusted macro definition is not used if gcc is not configured
with --enable-default-pie.
Bye.

ChangeLog:
* sysdeps/s390/s390-32/tls-macros.h (TLS_IE):
Use r12 for GOT address.
* sysdeps/s390/s390-64/tls-macros.h (TLS_IE): Likewise.
