            Bug ID: 18722
           Summary: Demangling C++ function name fails if clone suffix
                    contains digit
           Product: binutils
           Version: 2.26 (HEAD)
            Status: NEW
          Severity: minor
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: warieth at gmail dot com
  Target Milestone: ---

Created attachment 8453
  --> https://sourceware.org/bugzilla/attachment.cgi?id=8453&action=edit
test code, objdump output and patch

Using g++ (GCC) 5.2.0 and target attributes the generated funtion in object
code can't be demangled if the target contains digits (like arch_core2, ssse3,
sse4.2). The attachment contains the "objdump -C -t example.o" output, example
code and proposed patch.
