  39  * This class specifies IR node placeholder strings (also referred to as just "IR nodes") with mappings to regexes
  40  * depending on the selected compile phases. The mappings are stored in {@link #IR_NODE_MAPPINGS}. Each IR node
  41  * placeholder string is mapped to a {@link IRNodeMapEntry} instance defined in
  42  * {@link compiler.lib.ir_framework.driver.irmatching.mapping}.
  43  *
  44  * <p>
  45  * IR node placeholder strings can be used in {@link IR#failOn()} and/or {@link IR#counts()} attributes to define IR
  46  * constraints. They usually represent a single C2 IR node or a group of them.
  47  *
  48  * <p>
  49  * Each IR node placeholder string is accompanied by a static block that defines an IR node placeholder to regex(es)
  50  * mapping. The IR framework will automatically replace each IR node placeholder string in a user defined test with a
  51  * regex depending on the selected compile phases in {@link IR#phase} and the provided mapping.
  52  *
  53  * <p>
  54  * Each mapping must define a default compile phase which is applied when the user does not explicitly set the
  55  * {@link IR#phase()} attribute or when directly using {@link CompilePhase#DEFAULT}. In this case, the IR framework
  56  * falls back on the default compile phase of any {@link IRNodeMapEntry}.
  57  *
  58  * <p>
  59  * The IR framework reports a {@link TestFormatException} if:
  60  * <ul>
  61  *     <li><p> A user test specifies a compile phase for which no mapping is defined in this class.</li>
  62  *     <li><p> An IR node placeholder string is either missing a mapping or does not provide a regex for a specified
  63  *             compile phase in {@link IR#phase}.
  64  * </ul>
  65  *
  66  * <p>
  67  * There are two types of IR nodes:
  68  * <ul>
  69  *     <li><p>Normal IR nodes: The IR node placeholder string is directly replaced by a regex.</li>
  70  *     <li><p>Composite IR nodes:  The IR node placeholder string contains an additional {@link #COMPOSITE_PREFIX}.
  71  *                                 Using this IR node expects another user provided string in the constraint list of
  72  *                                 {@link IR#failOn()} and {@link IR#counts()}. They cannot be used as normal IR nodes.
  73  *                                 Trying to do so will result in a format violation error.</li>
  74  *     <li><p>Vector IR nodes:  The IR node placeholder string contains an additional {@link #VECTOR_PREFIX}.
  75  *                              Using this IR node, one can check for the type and size of a vector. The type must
  76  *                              be directly specified in {@link #vectorNode}. The size can be specified directly with
  77  *                              an additional argument using {@link #VECTOR_SIZE}, followed by a size tag or a comma
  78  *                              separated list of sizes. If the size argument is not given, then a default size of
  79  *                              {@link #VECTOR_SIZE_MAX} is taken, which is the number of elements that can fit in a
  80  *                              vector of the specified type (depends on the VM flag MaxVectorSize and CPU features).
  81  *                              However, when using {@link IR#failOn} or {@link IR#counts()} with comparison {@code <},
  82  *                              or {@code <=} or {@code =0}, the default size is {@link #VECTOR_SIZE_ANY}, allowing any
  83  *                              size. The motivation for these default values is that in most cases one wants to have
  84  *                              vectorization with maximal vector width, or no vectorization of any vector width.
  85  * </ul>
