Hi Bhushan
We ran into this problem whilst doing the Hexagon DSP support in LLDB.
This review was up (http://reviews.llvm.org/D4672) but is now stale
without reviewers. Basically we added the ability to the IR interpreter
to call functions on the target using a threadplan which manipulated the
stack and registers to call functions and capture any return values,
which works well on bare metal without ability to jit.
Maybe the patches can be of help to you. I doubt they would apply
cleanly now given the length of time since it was uploaded. It's a
valuable feature, but priorities on the list were elsewhere :)

Hi,
We are debugging a baremetal application using LLDB which is connected
to a remote target (supporting GDB remote protocol).
We are able to execute expressions involving global and frame
variables such as:
(lldb) expr var+4
However, LLDB is unable to execute expressions involving function calls.
(lldb) expr (int) bar(1,2)
error: Can't run the expression locally: Interpreter doesn't handle
one of the expression's opcodes
Function bar is defined as int bar(int, int).
The expression execution_policy is set to eExecutionPolicyNever as
CanJIT() returns false for baremetal applications.
This is because JIT is disabled for static dynamic loader targets.
TheIRInterpreter::CanInterpret returns false as it fails to interpret
call instruction (call to 'bar' is not an intrinsic).
Could you please help us on this?
-Regards
Bhushan
