gdb: i386 Features

 
 G.5.4 i386 Features
 -------------------
 
 The 'org.gnu.gdb.i386.core' feature is required for i386/amd64 targets.
 It should describe the following registers:
 
    - 'eax' through 'edi' plus 'eip' for i386
    - 'rax' through 'r15' plus 'rip' for amd64
    - 'eflags', 'cs', 'ss', 'ds', 'es', 'fs', 'gs'
    - 'st0' through 'st7'
    - 'fctrl', 'fstat', 'ftag', 'fiseg', 'fioff', 'foseg', 'fooff' and
      'fop'
 
    The register sets may be different, depending on the target.
 
    The 'org.gnu.gdb.i386.sse' feature is optional.  It should describe
 registers:
 
    - 'xmm0' through 'xmm7' for i386
    - 'xmm0' through 'xmm15' for amd64
    - 'mxcsr'
 
    The 'org.gnu.gdb.i386.avx' feature is optional and requires the
 'org.gnu.gdb.i386.sse' feature.  It should describe the upper 128 bits
 of YMM registers:
 
    - 'ymm0h' through 'ymm7h' for i386
    - 'ymm0h' through 'ymm15h' for amd64
 
    The 'org.gnu.gdb.i386.mpx' is an optional feature representing Intel
 Memory Protection Extension (MPX). It should describe the following
 registers:
 
    - 'bnd0raw' through 'bnd3raw' for i386 and amd64.
    - 'bndcfgu' and 'bndstatus' for i386 and amd64.
 
    The 'org.gnu.gdb.i386.linux' feature is optional.  It should describe
 a single register, 'orig_eax'.
 
    The 'org.gnu.gdb.i386.segments' feature is optional.  It should
 describe two system registers: 'fs_base' and 'gs_base'.
 
    The 'org.gnu.gdb.i386.avx512' feature is optional and requires the
 'org.gnu.gdb.i386.avx' feature.  It should describe additional XMM
 registers:
 
    - 'xmm16h' through 'xmm31h', only valid for amd64.
 
    It should describe the upper 128 bits of additional YMM registers:
 
    - 'ymm16h' through 'ymm31h', only valid for amd64.
 
    It should describe the upper 256 bits of ZMM registers:
 
    - 'zmm0h' through 'zmm7h' for i386.
    - 'zmm0h' through 'zmm15h' for amd64.
 
    It should describe the additional ZMM registers:
 
    - 'zmm16h' through 'zmm31h', only valid for amd64.
 
    The 'org.gnu.gdb.i386.pkeys' feature is optional.  It should describe
 a single register, 'pkru'.  It is a 32-bit register valid for i386 and
 amd64.
