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.XirAssembler.XirInstruction XIR instructions} that has * unbound {@link com.oracle.max.cri.xir.XirAssembler.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.XirAssembler}, which provides methods to create instructions and operands. */ package com.oracle.max.cri.xir;
