Subject: [Bug libstdc++/46347] New: Profile-mode executables too large
Date: Sun, 07 Nov 2010 15:48:00 -0000	[thread overview]
Message-ID: <bug-46347-4@http.gcc.gnu.org/bugzilla/> (raw)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46347

           Summary: Profile-mode executables too large
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: paolo.carlini@oracle.com


I believe we should seriously investigate whether we can reduce the size of the
profile-mode executables. Likely that means we have also to add exports, but
the current status seems really pretty bad. Just as a trivial example, on
mainline today (rev 166416), x86_64, -O2, we have, for

#include <vector>

int main()
{
  std::vector<int> v(100);
  v.push_back(2);
}

the following sizes:

 normal-mode:    12184
  debug-mode:    17370
profile-mode:   130345
