- Date: Wed, 05 Sep 2012 21:13:47 -0400 (EDT)
- Subject: [PATCH] Recognize new sparc hwcap bits.
This teaches glibc about the new hwcap feature bits that represent
facilities which show up starting with the SPARC-T4 cpu.
Committed to master.
* sysdeps/sparc/bits/hwcap.h (HWCAP_SPARC_PAUSE,
HWCAP_SPARC_CBCOND, HWCAP_SPARC_CRYPTO): Define.
* sysdeps/sparc/dl-procinfo.h (_DL_HWCAP_COUNT): Increase to 27.
* sysdeps/sparc/dl-procinfo.c (_dl_sparc_cap_flags): Add new
entries.
