Functions in this group relate to the inspection and manipulation of individual instructions.

In the C++ API, an instruction is modeled by llvm::Instruction. This class has a large number of descendents. llvm::Instruction is a llvm::Value and in the C API, instructions are modeled by LLVMValueRef.

This group also contains sub-groups which operate on specific llvm::Instruction types, e.g. llvm::CallInst.

◆ LLVMGetNextInstruction()

Obtain the instruction that occurs after the one specified.

The next instruction will be from the same basic block.

If this is the last instruction in a basic block, NULL will be returned.

◆ LLVMGetPreviousDbgRecord()

◆ LLVMGetPreviousInstruction()

Obtain the instruction that occurred before this one.

If the instruction is the first instruction in a basic block, NULL will be returned.
