[Lldb-commits] [lldb] r243736 - Move the computation of whether a DWARF compile unit

[Jason Molenda]

New Revision: 243736

URL: http://llvm.org/viewvc/llvm-project?rev=243736&view=rev
Log:
Move the computation of whether a DWARF compile unit
is optimized into DWARFCompileUnit, where it should have
been.  Next I'll need to call this from another section 
of code for DWARF-in-.o-file behavior correctness.
