[Bug tdep/16397] New: SystemTap SDT probe support for x86 doesn't work with "triplet operands"


https://sourceware.org/bugzilla/show_bug.cgi?id=16397

            Bug ID: 16397
           Summary: SystemTap SDT probe support for x86 doesn't work with
                    "triplet operands"
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tdep
          Assignee: sergiodj at redhat dot com
          Reporter: sergiodj at redhat dot com

The SystemTap SDT probe implementation for x86 (i*86 and x86_64) support, in
theory, what we call "triplet operands", i.e., "-8+3+1(%rbp)".  However, the
current code has a bug and doesn't support this in the right way.

I've already have a fix and a testcase for it.  This bug is mostly a "don't
forget" :-).
