This patch allows examination of the registers FS_BASE and GS_BASE for Linux Systems running on 64bit. Tests for simple read and write of the new registers is also added with this patch. 2017-01-27 Walfred Tedeschi <walfred.tedeschi@intel.com> Richard Henderson <rth@redhat.com> gdb/ChangeLog: * amd64-linux-nat.c (PTRACE_ARCH_PRCTL): New define. (amd64_linux_fetch_inferior_registers): Add case to fetch FS_BASE GS_BASE for older kernels. (amd64_linux_store_inferior_registers): Add case to store FS_BASE GS_BASE for older kernels. * amd64-linux-tdep.c (amd64_linux_gregset_reg_offset): Add FS_BASE and GS_BASE to the offset table. (amd64_linux_register_reggroup_p): Add FS_BASE and GS_BASE to the system register group. * amd64-nat.c (amd64_native_gregset_reg_offset): Implements case for older kernels. * amd64-tdep.c (amd64_init_abi): Add segment registers for the amd64 ABI. * amd64-tdep.h (amd64_regnum): Add AMD64_FSBASE_REGNUM and AMD64_GSBASE_REGNUM.
