commit 1a7df49c92f62e14d8727f083fd055eba7c91ad9
Author: Stefan Liebler <stli@linux.ibm.com>
Date: Fri Mar 22 11:14:07 2019 +0100
S390: Add new hwcap values for new cpu architecture arch13.
The new hwcap values indicate support for:
-"Vector-Enhancements Facility 2" (tag "vxe2", hwcap 2^15)
-"Vector-Packed-Decimal-Enhancement Facility" (tag "vxp", hwcap 2^16)
-"Enhanced-Sort Facility" (tag "sort", hwcap 2^17)
-"Deflate-Conversion Facility" (tag "dflt", hwcap 2^18)
The vxe2 hwcap is also marked as important hwcap.
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags):
Add vxe2, vxp, dflt, sort flags.
* sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXRS_EXT2,
HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT
capabilities.
(HWCAP_IMPORTANT): Add HWCAP_S390_VXRS_EXT2.
* sysdeps/unix/sysv/linux/s390/bits/hwcap.h
(HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT,
HWCAP_S390_DFLT): Define.
