[lldb-dev] Expressions on baremetal target

[Bhushan Attarde]

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.
The IRInterpreter::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
