Detailed Description

Context needed to emit a p-code injection as a full set of p-code operations.

P-code injection works by passing a pre-built template of p-code operations (ConstructTpl) to an emitter (PcodeEmit), which makes the final resolution SLEIGH concepts like inst_next to concrete Varnodes. This class contains the context dependent data to resolve:

• inst_start – the address where the injection occurs
• inst_next – the address of the instruction following (the instruction being injected)
• inst_next2 – the address of the instruction after the next instruction (Not Supported)
• inst_dest – Original destination of CALL being injected
• inst_ref – Target of reference on injected instruction
• <input> – Input Varnode of the injection referenced by name
• <output> – Output Varnode of the injection referenced by name
