2013-05-16 Ryan S. Arnold <rsa@linux.vnet.ibm.com>
+ * sysdeps/powerpc/bits/hwcap.h: Add new AT_HWCAP2 features.
+ [PPC_FEATURE2_ARCH_2_07]: New feature bit for Power ISA 2.07.
+ [PPC_FEATURE2_HAS_HTM]: New feature bit for Hardware Transactional
+ Memory.
+ [PPC_FEATURE2_HAS_DSCR]: New feature bit for Data Stream Control
+ Register.
+ [PPC_FEATURE2_HAS_EBB]: New feature bit for Event Based Branching
+ facility.
+ [PPC_FEATURE2_HAS_ISEL]: New feature bit for Integer Select.
+ [PPC_FEATURE2_HAS_TAR]: New feature bit for Target Address Register
+ facility.
+ * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_platforms): Add power8 as
+ PPC_PLATFORM_POWER8.
+ (_dl_powerpc_cap_flags): Add arch_2_07, htm, dscr, ebb, isel, and tar
+ as hwcap strings for power8.
+ * sysdeps/powerpc/dl-procinfo.h (_dl_procinfo): Eliminate confusing
+ conditional variable definitions used to re-use a single loop
+ definition. Replace with simpler redundant loops. Account for
+ AT_HWCAP2 feature bits starting at bit 31 and decrementing.
+ [_DL_HWCAP_LAST]: New definition.
+ [_DL_HWCAP2_LAST]: New definition.
+ [_DL_HWCAP_COUNT]: Update to 64 to account for available bits, not
+ number of actual hwcap bits that are defined.
+ [_DL_PLATFORMS_COUNT]: Increment for power8.
+ [PPC_PLATFORM_POWER8]: New definition.
+ (_dl_string_platform): Add return value for power8 platform string.
+ * sysdeps/powerpc/powerpc32/power8/Implies: New file.
+ * sysdeps/powerpc/powerpc64/power8/Implies: Likewise.
+ * sysdeps/unix/sysv/linux/powerpc/powerpc32/power8/Implies: Likewise.
+ * sysdeps/unix/sysv/linux/powerpc/powerpc64/power8/Implies: Likewise.

* sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_platforms): Add ppc405,
ppc440, ppc464, and ppc476, merging from ports/ dl-procinfo.c.
* sysdeps/powerpc/dl-procinfo.h: Fix whitespace by correcting spaces
