             Bug #: 13767
           Summary: "info float" and unavailable float registers
                    (traceframes)
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: palves@redhat.com
    Classification: Unclassified


On x86*:

(gdb) trace foo
(gdb) tstart
(gdb) ...
(gdb) tstop
(gdb) tfind
(gdb) info float 
Register 32 is not available

i387-tdep.c:i387_print_float_info isn't handling unavailable-ness gracefully.
