[PATCH] S390: Get rid of linknamespace failures for string functions.

[Stefan Liebler]

Hi,

i get the following linknamespace-testsuite failures on s390-32/s390-64:

FAIL: conform/ISO/string.h/linknamespace
FAIL: conform/ISO11/string.h/linknamespace
FAIL: conform/ISO99/string.h/linknamespace
FAIL: conform/POSIX/string.h/linknamespace
FAIL: conform/POSIX2008/string.h/linknamespace
FAIL: conform/UNIX98/string.h/linknamespace
FAIL: conform/UNIX98/strings.h/linknamespace
FAIL: conform/XOPEN2K/string.h/linknamespace
FAIL: conform/XOPEN2K/strings.h/linknamespace
FAIL: conform/XOPEN2K8/string.h/linknamespace
FAIL: conform/XPG3/string.h/linknamespace
FAIL: conform/XPG4/string.h/linknamespace
FAIL: conform/XPG4/strings.h/linknamespace
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memcmp_z10
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memcmp_z196
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memcmp_z900
[initial] memcpy -> [libc.a(memcpy.o)] memcpy_mvcle
[initial] memcpy -> [libc.a(memcpy.o)] memcpy_z900
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memset_z10 -> 
[libc.a(memset.o)] memset_mvcle
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memset_z10
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memset_z196
[initial] memcmp -> [libc.a(ifunc-resolve.o)] memset_z900
[initial] memcmp -> [libc.a(ifunc-resolve.o)] resolve_memcmp
[initial] memcmp -> [libc.a(ifunc-resolve.o)] resolve_memset
conform/ISO/string.h/linknamespace.out (END)

There exists multiple functions for memcpy, memset, memcmp.
For those the ifunc-resolver-function and each specific function
pollutes the namespace.

This patch prefixes the ifunc-resolvers, the specific functions
and helper functions with '__' on s390-32/s390-64.

The mentioned testsuite-failures are passing now
and there are no new failures.

Ok to commit?

Bye
Stefan
