[Bug libgcj/11385] New: compute GC bitmap values at runtime


PLEASE REPLY TO gcc-bugzilla@gcc.gnu.org ONLY, *NOT* gcc-bugs@gcc.gnu.org.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11385

           Summary: compute GC bitmap values at runtime
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libgcj
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: tromey at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

Currently we don't compute GC object layout bitmaps
at runtime; only at compile time.  This affects all
classes using -fno-assume-compiled and will affect
-findirect-dispatch at all.  for such classes the
computation must be deferred to runtime.  we should do
this at class init. to get best performance from
the GC.
