MPX for amd64
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.
