Subject: [PATCH 06/30] S390: Add hwcaps value for vector facility. |
|
|
|
upstream-commit-id: 4e28fa80886c71e6aaf85016b82ce981c0f12e6d |
|
https://www.sourceware.org/ml/libc-alpha/2015-07/msg00075.html |
|
|
|
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. |
