S390: Use hwcap instead of dl_hwcap in ifunc-resolvers.
|
||
|
|
|
||
|
|
The renaming of hwcap arguments in ifunc-resolvers is needed
|
||
|
|
in order to prepare for further commits which refactors
|
||
|
|
ifunc handling for memset, memcmp, and memcpy. Now you are able
|
||
|
|
to use s390_libc_ifunc_init which stores the stfle bits
|
||
|
|
within the expression for an ifunc-resolver generated by
|
||
|
|
s390_libc_ifunc_expr.
|
||
|
|
|
||
|
|
ChangeLog:
|
||
|
|
|
||
|
|
* sysdeps/s390/multiarch/ifunc-resolve.h
|
||
|
|
(s390_libc_ifunc_init, s390_libc_ifunc,
|
||
|
|
s390_vx_libc_ifunc2_redirected): Use hwcap instead of dl_hwcap.
