Detailed Description

"lldb/Core/EmulateInstruction.h" A class that allows emulation of CPU opcodes.

This class is a plug-in interface that is accessed through the standard static FindPlugin function call in the EmulateInstruction class. The FindPlugin takes a target triple and returns a new object if there is a plug-in that supports the architecture and OS. Four callbacks and a baton are provided. The four callbacks are read register, write register, read memory and write memory.

This class is currently designed for these main use cases: - Auto generation of Call Frame Information (CFI) from assembly code - Predicting single step breakpoint locations - Emulating instructions for breakpoint traps

Objects can be asked to read an instruction which will cause a call to the read register callback to get the PC, followed by a read memory call to read the opcode. If ReadInstruction () returns true, then a call to EmulateInstruction::EvaluateInstruction () can be made. At this point the EmulateInstruction subclass will use all of the callbacks to emulate an instruction.

Clients that provide the callbacks can either do the read/write registers/memory to actually emulate the instruction on a real or virtual CPU, or watch for the EmulateInstruction::Context which is context for the read/write register/memory which explains why the callback is being called. Examples of a context are: "pushing register 3 onto the stack at offset -12", or "adjusting stack pointer by -16". This extra context allows the generation of CFI information from assembly code without having to actually do the read/write register/memory.

Clients must be prepared that not all instructions for an Instruction Set Architecture (ISA) will be emulated.

Subclasses at the very least should implement the instructions that save and restore registers onto the stack and adjustment to the stack pointer. By just implementing a few instructions for an ISA that are the typical prologue opcodes, you can then generate CFI using a class that will soon be available.

Implementing all of the instructions that affect the PC can then allow single step prediction support.

Implementing all of the instructions allows for emulation of opcodes for breakpoint traps and will pave the way for "thread centric" debugging. The current debugging model is "process centric" where all threads must be stopped when any thread is stopped; when hitting software breakpoints we must disable the breakpoint by restoring the original breakpoint opcode, single stepping and restoring the breakpoint trap. If all threads were allowed to run then other threads could miss the breakpoint.

This class centralizes the code that usually is done in separate code paths in a debugger (single step prediction, finding save restore locations of registers for unwinding stack frame variables) and emulating the instruction is just a bonus.
