[Lldb-commits] [lldb] r180899 - Since the IR interpreter does not (currently)

[Sean Callanan]

Author: spyffe
Date: Wed May  1 19:33:44 2013
New Revision: 180899

URL: http://llvm.org/viewvc/llvm-project?rev=180899&view=rev
Log:
Since the IR interpreter does not (currently)
support operands with vector types, it now reports
that it cannot interpret expressions that use
vector types.  They get sent to the JIT instead.
