◆ EmulateOutlinedFunction()

bool UnwindAssemblyInstEmulation::EmulateOutlinedFunction ( lldb_private::Address func_addr)
private

Follow a call into a compiler-outlined helper and emulate its body in the caller's state.

Outlined functions don't respect ABI, which is why this unwinder must follow outlined function calls. A prime target for outlining is function prologues. This function supports emulating straightline code with no branches, which is the case for prologues.
