+PT_GNU_SFRAME    0x6474e554
+
+  Segment contains the SFrame section (Simple Frame format stack trace
+  information).
+
+  NOTE: The virtual address range referred to by PT_GNU_SFRAME must be covered
+  by a PT_LOAD entry - PT_GNU_SFRAME on its own does not trigger the
+  mapping/loading of any data.
+
+  The contents of the SFrame section are described in the GNU Binutils
+  documentation.  As of 2.40:
+
+  https://sourceware.org/binutils/docs/sframe-spec.html
+
 There are further extensions to p_type but currently they are all
 architecture specific and should be documented in the relevant ABIs.
