[PATCH V9 01/28] elf: Add powerpc specific core note sections

From: Anshuman Khandual
Date: Thu Oct 08 2015 - 10:49:05 EST


This patch adds twelve ELF core note sections for powerpc
architecture for various registers and register sets which
need to be accessed from ptrace interface and then gdb.
These additions include special purpose registers like TAR,
PPR, DSCR, TM running and checkpointed state for various
register sets, EBB related register set etc. Addition of
these new ELF core note sections extends the existing ELF
ABI on powerpc arch without affecting it in any manner.
