@cindex target descriptions, i386 features
The @samp{org.gnu.gdb.i386.core} feature is required for i386/amd64
targets. It should describe the following registers:
@itemize @minus
@item
@samp{eax} through @samp{edi} plus @samp{eip} for i386
@item
@samp{rax} through @samp{r15} plus @samp{rip} for amd64
@item
@samp{eflags}, @samp{cs}, @samp{ss}, @samp{ds}, @samp{es},
@samp{fs}, @samp{gs}
@item
@samp{st0} through @samp{st7}
@item
@samp{fctrl}, @samp{fstat}, @samp{ftag}, @samp{fiseg}, @samp{fioff},
@samp{foseg}, @samp{fooff} and @samp{fop}
@end itemize
The register sets may be different, depending on the target.
The @samp{org.gnu.gdb.i386.sse} feature is required. It should
describe registers:
@itemize @minus
@item
@samp{xmm0} through @samp{xmm7} for i386
@item
@samp{xmm0} through @samp{xmm15} for amd64
@item
@samp{mxcsr}
@end itemize
The @samp{org.gnu.gdb.i386.linux} feature is optional. It should
describe a single register, @samp{orig_eax}.
