S390: Use hwcap instead of dl_hwcap in ifunc-resolvers.
|
|
|
bdc76f |
|
|
|
bdc76f |
The renaming of hwcap arguments in ifunc-resolvers is needed
|
|
|
bdc76f |
in order to prepare for further commits which refactors
|
|
|
bdc76f |
ifunc handling for memset, memcmp, and memcpy. Now you are able
|
|
|
bdc76f |
to use s390_libc_ifunc_init which stores the stfle bits
|
|
|
bdc76f |
within the expression for an ifunc-resolver generated by
|
|
|
bdc76f |
s390_libc_ifunc_expr.
