            Bug ID: 107513
           Summary: [Feature Request] Implement
                    __attribute__((__nodebug__))
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roi.jacobson1 at gmail dot com
  Target Milestone: ---

Clang has __attribute__((__nodebug__)). When applied for types and functions it
suppresses generation of debug information for those types or functions. This
can greatly reduce binary sizes when compiling with debug symbols.

As a very non representative measure: in a library I'm currently working on, by
applying this attribute to some uninteresting 'forwarding' functions I see a
40% reduction in size (uncompressed and unrepresentative, but still).

It is worth noting that this attribute is already used in libc++ and in some
other libraries (for example Apple SIMD).
