Detailed Description

"lldb/Expression/IRExecutionUnit.h" Contains the IR and, optionally, JIT- compiled code for a module.

This class encapsulates the compiled version of an expression, in IR form (for interpretation purposes) and in raw machine code form (for execution in the target).

This object wraps an IR module that comes from the expression parser, and knows how to use the JIT to make it into executable code. It can then be used as input to the IR interpreter, or the address of the executable code can be passed to a thread plan to run in the target.

This class creates a subclass of LLVM's SectionMemoryManager, because that is how the JIT emits code. Because LLDB needs to move JIT-compiled code into the target process, the IRExecutionUnit knows how to copy the emitted code into the target process.

m_reported_allocations

bool lldb_private::IRExecutionUnit::m_reported_allocations

private

True after allocations have been reported.

It is possible that sections will be allocated when this is true, in which case they weren't depended on by any function. (Top-level code defining a variable, but defining no functions using that variable, would do this.) If this is true, any allocations need to be committed immediately – no opportunity for relocation.
