Author: labath Date: Wed Sep 5 07:38:44 2018 New Revision: 341472 URL: http://llvm.org/viewvc/llvm-project?rev=341472&view=rev Log: Enable DWARF accelerator tables by default when tuning for lldb (-glldb => -gpubnames)
Summary: DWARF v5 accelerator tables provide a considerable performance improvement for lldb and will make the default -glldb behavior same on all targets (right now we emit apple tables on apple targets, but these are not controlled by -gpubnames, only by -glldb).
