+// gcc's runtime support libraries use to find unwind information at
+// runtime.
+
+// The exception frame header starts with four bytes:
+
+// 0: The version number, currently 1.
+
+// 1: The encoding of the pointer to the exception frames.  This can
+//    be any DWARF unwind encoding (DW_EH_PE_*).  It is normally a 4
+//    byte PC relative offset (DW_EH_PE_pcrel | DW_EH_PE_sdata4).
+
+// 2: The encoding of the count of the number of FDE pointers in the
+//    lookup table.  This can be any DWARF unwind encoding, and in
+//    particular can be DW_EH_PE_omit if the count is omitted.  It is
+//    normally a 4 byte unsigned count (DW_EH_PE_udata4).
+
+// 3: The encoding of the lookup table entries.  Currently gcc's
+//    libraries will only support DW_EH_PE_datarel | DW_EH_PE_sdata4,
+//    which means that the values are 4 byte offsets from the start of
+//    the table.
+
+// The exception frame header is followed by a pointer to the contents
+// of the exception frame section (.eh_frame).  This pointer is
+// encoded as specified in the byte at offset 1 of the header (i.e.,
+// it is normally a 4 byte PC relative offset).
+
+// If there is a lookup table, this is followed by the count of the
+// number of FDE pointers, encoded as specified in the byte at offset
+// 2 of the header (i.e., normally a 4 byte unsigned integer).
+
+// This is followed by the table, which should start at an 4-byte
+// aligned address in memory.  Each entry in the table is 8 bytes.
+// Each entry represents an FDE.  The first four bytes of each entry
+// are an offset to the starting PC for the FDE.  The last four bytes
+// of each entry are an offset to the FDE data.  The offsets are from
+// the start of the exception frame header information.  The entries
