From: Walfred Tedeschi Date: Fri, 27 Jan 2017 14:19:14 +0000 (+0100) Subject: amd64-linux: expose system register FS_BASE and GS_BASE for Linux. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2735833d5fb220983d09770087b573fed5bf93cd;p=binutils-gdb.git amd64-linux: expose system register FS_BASE and GS_BASE for Linux. 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 Richard Henderson 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.
