[Bug gdb/15568] New: Expose ucontext for signals


http://sourceware.org/bugzilla/show_bug.cgi?id=15568

            Bug ID: 15568
           Summary: Expose ucontext for signals
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: luto at mit dot edu

The ucontext struct in a signal frame has all kinds of useful (target-specific)
information.  A lot of it shows up in "info regs", but some is missing.  For
example, on x86, cr2 and err can be quite useful.  Please expose it somehow
(perhaps with a magic variable $_sigcontext).
