/**
 * XIR defines a domain specific instruction set for expressing the lowering of bytecode operations. The details of the
 * lowering operations are entirely encapsulated in the runtime and are provided to the compiler on request using
 * {@link com.oracle.max.cri.xir.XirSnippet XIR snippets}. A snippet is a combination of a {@link com.oracle.max.cri.xir.XirTemplate
 * template}, which is a sequence of {@link com.oracle.max.cri.xir.CiXirAssembler.XirInstruction XIR instructions} that has
 * unbound {@link com.oracle.max.cri.xir.CiXirAssembler.XirParameter parameters}, and site-specific
 * {@link com.oracle.max.cri.xir.XirArgument arguments} that are bound to the parameters.
 * <p>
 * The runtime is responsible for creating the {@link com.oracle.max.cri.xir.XirTemplate templates} and provides these to the
 * compiler as part of the initialization process.
 * <p>
 * The XIR instruction set has no textual representation, and therefore no parser. An assembly is represented by an
 * instance of {@link com.oracle.max.cri.xir.CiXirAssembler}, which provides methods to create instructions and operands.
