(i386_frame_this_id, i386_sigtramp_frame_this_id,
i386_dummy_id). It's there, since all frame unwinders for
a given target have to agree (within a certain margin) on the
- definition of the stack address of a frame. Otherwise
- frame_id_inner() won't work correctly. Since DWARF2/GCC uses the
+ definition of the stack address of a frame. Otherwise frame id
+ comparison might not work correctly. Since DWARF2/GCC uses the
stack address *before* the function call as a frame's CFA. On
the i386, when %ebp is used as a frame pointer, the offset
between the contents %ebp and the CFA as defined by GCC. */
