commit 0c03cb54c808173d8e7ba96f6152dfcf627ac496

S390: Add new s390 platform z16.
|
|
|
|
The new IBM z16 is added to platform string array.
|
|
The macro _DL_PLATFORMS_COUNT is incremented.
|
|
|
|
_dl_hwcaps_subdir is extended by "z16" if HWCAP_S390_VXRS_PDE2
|
|
is set. HWCAP_S390_NNPA is not tested in _dl_hwcaps_subdirs_active
|
|
as those instructions may be replaced or removed in future.
|
|
|
|
tst-glibc-hwcaps.c is extended in order to test z16 via new marker5.
|
|
|
|
A fatal glibc error is dumped if glibc was build with architecture
|
|
level set for z16, but run on an older machine. (See dl-hwcap-check.h)
|
|
|
|
(cherry picked from commit 2376944b9e5c0364b9fb473e4d8dabca31b57167)

- Backported f01d482f0355a7029d0715ace0ccf3323e7e94bc requires it.
