Ok, so there are two restore_state notes following each other; note 374 and
note 375. We'll want a breakpoint in add_cfi to catch the two calls where these
notes are added. I'd expect it's from connect_traces, and at
cfi->dw_cfi_opc = DW_CFA_restore_state;
add_cfi (cfi);
in that function I'd like to see some state:
p debug_rtx (prev_ti->head)
p debug_rtx (ti->head)
p debug_cfi_row (ti->beg_row)
for each time we reach this code.
