<div dir="ltr">Hi Ryan, my change to the test system seems to have crossed paths with this CL. tests don't go in lldb/test anymore, they go in lldb/packages/Python/lldbsuite/test. Right now these are the only tests still in the wrong location, so they aren't getting run. You will need to move them over to the new location.</div><br><div class="gmail_quote"><div dir="ltr">On Mon, Nov 2, 2015 at 11:33 AM Ryan Brown via lldb-commits <<a href="mailto:lldb-commits@lists.llvm.org">lldb-commits@lists.llvm.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Author: ribrdb<br>

Log:<br>
Create an expression parser for Go.<br>
<br>
The Go interpreter doesn't JIT or use LLVM, so this also<br>
moves all the JIT related code from UserExpression to a new class LLVMUserExpression.<br>
