Hi Geoff<br>
<br>
<blockquote type="cite">LLVM ERROR: Associative COMDAT symbol
'GVName' is not a key for its COMDAT.</blockquote>
This is in CodeGen TargetLoweringObjectFileCOFF so this isn't
necessarily JIT specific. Maybe a backtrace would be helpful?<br>

<blockquote type="cite">lli --jit-end=orc-lazy hello.bc</blockquote>
Greedy Orc mode recently landed in lli:

You might want to retry with that in order to rule out the
lazy-JIT-infrastructure as a cause for the error.<br>

I am not aware of anyone actively working on improved Orc Windows
support right now.<br>

<div>I know Orc JIT lacks COMDAT support, but I thought that
just caused duplicate symbols sometimes. Am I doing
something stupid here? Or should I just give up now on
porting our Orc-based application to Windows? (The
application JIT-compiles C++ modules which rely heavily on
STL.)<br>
