------- Comment #12 from jakub at gcc dot gnu dot org 2008-08-13 08:54 ------- After more thinking, I'm not convinced even debuggers need it when frame pointer is present (as Jan just told me, gdb ignores DW_CFA_GNU_args_size altogether anyway). The current sp comes up just from unwinding through a lower frame, and the next sp value will be read from fp.
