From d87bf6412b4cb0a5cd174d746eb596158075a5bb Mon Sep 17 00:00:00 2001 From: Stefan Liebler <stli@linux.vnet.ibm.com> Date: Mon, 4 Apr 2016 12:54:22 +0200 Subject: [PATCH 53/65] S390: Add hwcaps value for vector facility. The HWCAP_S390_VX flag in hwcap field of auxiliary vector indicates if the vector facility is available and the kernel is aware of it. This can be tested with LD_SHOW_AUXV=1 <prog>. Currently it does not show te, because it was not incremented by commit "S/390: Add hwcap value for transactional execution.". Thus _DL_HWCAP_COUNT is incremented by two. ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_platforms): Add vector flag. * sysdeps/s390/dl-procinfo.h: Add vector capability. * sysdeps/unix/sysv/linux/s390/bits/hwcap.h (HWCAP_S390_VX): Define.
