2013-06-24 Walfred Tedeschi <walfred.tedeschi@intel.com>
* amd64-linux-nat.c (amd64_linux_gregset32_reg_offset):
Add MPX registers.
(amd64_linux_read_description): Add initialization for MPX and
AVX independently.
* amd64-linux-tdep.c: Includes features/i386/amd64-mpx-linux.c.
(amd64_linux_gregset_reg_offset): Add MPX registers.
(amd64_linux_core_read_description): Add initialization for MPX
registers.
(_initialize_amd64_linux_tdep): Initialize MPX targets.
* amd64-linux-tdep.h (AMD64_LINUX_RAX_REGNUM): Set it to the last
register on the list.
(tdesc_amd64_mpx_linux) Add new target for MPX.
* amd64-tdep.c: Includes features/i386/amd64-mpx.c.
(amd64_mpx_names): MPX register names.
(amd64_init_abi): Add MPX register while initializing the ABI.
(_initialize_amd64_tdep): Initialize MPX targets.
* amd64-tdep.h (amd64_regnum): Add MPX registers.
(AMD64_NUM_REGS): Set number of registers taking MPX into account.
