S390: Cleanup ifunc-resolve.h.
|
||
|
|
|
||
|
|
The ifunc macros s390_vx_libc* are no longer used and
|
||
|
|
can be removed as all users are now relying on
|
||
|
|
s390_libc_ifunc_expr.
|
||
|
|
|
||
|
|
The same applies to s390_libc_ifunc. The macro
|
||
|
|
s390_libc_ifunc_init is now renamed to
|
||
|
|
s390_libc_ifunc_expr_stfle_init and the users are
|
||
|
|
adjusted accordingly.
|
||
|
|
|
||
|
|
ChangeLog:
|
||
|
|
|
||
|
|
* sysdeps/s390/multiarch/ifunc-resolve.h
|
||
|
|
(s390_vx_libc_ifunc, s390_vx_libc_ifunc_redirected,
|
||
|
|
s390_vx_libc_ifunc2, s390_vx_libc_ifunc_init,
|
||
|
|
s390_vx_libc_ifunc2_redirected, s390_libc_ifunc):
|
||
|
|
Delete macro definition.
|
||
|
|
(s390_libc_ifunc_init): Rename to
|
||
|
|
s390_libc_ifunc_expr_stfle_init.
|
||
|
|
* sysdeps/s390/bzero: Use
|
||
|
|
s390_libc_ifunc_expr_stfle_init instead of
|
||
|
|
s390_libc_ifunc_init.
|
||
|
|
* sysdeps/s390/memcmp.c: Likewise.
|
||
|
|
* sysdeps/s390/memcpy.c: Likewise.
|
||
|
|
* sysdeps/s390/mempcpy.c: Likewise.
|
||
|
|
* sysdeps/s390/memset.c: Likewise.
