| 24 * XIR defines a domain specific instruction set for expressing the lowering of bytecode operations. The details of the | |
| 25 * lowering operations are entirely encapsulated in the runtime and are provided to the compiler on request using | |
| 26 * {@link com.oracle.max.cri.xir.XirSnippet XIR snippets}. A snippet is a combination of a {@link com.oracle.max.cri.xir.XirTemplate | |
| 27 * template}, which is a sequence of {@link com.oracle.max.cri.xir.CiXirAssembler.XirInstruction XIR instructions} that has | |
| 28 * unbound {@link com.oracle.max.cri.xir.CiXirAssembler.XirParameter parameters}, and site-specific | |
| 29 * {@link com.oracle.max.cri.xir.XirArgument arguments} that are bound to the parameters. | |
| 30 * <p> | |
| 31 * The runtime is responsible for creating the {@link com.oracle.max.cri.xir.XirTemplate templates} and provides these to the | |
| 32 * compiler as part of the initialization process. | |
| 33 * <p> | |
| 34 * The XIR instruction set has no textual representation, and therefore no parser. An assembly is represented by an | |
| 35 * instance of {@link com.oracle.max.cri.xir.CiXirAssembler}, which provides methods to create instructions and operands. | |
