John Baldwin 180e57e5c7 Improve support for XSAVE with debuggers. ... - Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed to match what Linux does in that 1) it dumps the entire XSAVE area including the fxsave state, and 2) it stashes a copy of the current xsave mask in the unused padding between the fxsave state and the xstate header at the same location used by Linux. - Teach readelf() to recognize NT_X86_XSTATE notes. - Change PT_GET/SETXSTATE to take the entire XSAVE state instead of only the extra portion. This avoids having to always make two ptrace() calls to get or set the full XSAVE state. - Add a PT_GET_XSTATE_INFO which returns the length of the current XSTATE save area (so the size of the buffer needed for PT_GETXSTATE) and the current XSAVE mask (%xcr0).
