llvm dev - Dec 2020 - Fwd: [lli][compiler-rt][halfType] lli segfaults while executing half type.

Hi all,

I have an LLVM IR (attached) that contain half types. This IR does a simple
addition of float and half variables. The half type conversions call
"__gnu_h2f_ieee"
function from compiler-rt, which means I need to link against compiler-rt.

While I can do this with `llc' workflow by using the
"--rtlib=compiler-rt"
option for clang, I could not find a way to call in compiler-rt libraries
while running with `lli'.

Is there a way to specify compiler-rt libs for lli?

Currently, lli segfaults while executing the attached IR. So I had posted a
bug on this a while back at https://bugs.llvm.org/show_bug.cgi?id=48213, but
thought of asking it here since it is a generic issue.

Thanks
Vikram
