Subject: PATCH: PR c++/49412: __dso_handle should be hidden
Date: Wed, 15 Jun 2011 13:48:00 -0000 [thread overview]
Message-ID: <20110615130701.GA13377@intel.com> (raw)
Since __dso_handle is always hidden if HAVE_GAS_HIDDEN is set, it is safe
to mark __dso_handle hidden if assembler supports it. OK for trunk?
Thanks.
H.J.
