| <h1>filled-new-array/range</h1> |
| |
| <h2>Purpose</h2> |
| |
| <p> |
| Construct an array of the given type and size, filling it with the supplied |
| contents. Clarifications and restrictions are the same as filled-new-array, |
| described above. |
| </p> |
| |
| <h2>Details</h2> |
| |
| <table class="instruc"> |
| <thead> |
| <tr> |
| <th>Op & Format</th> |
| <th>Mnemonic / Syntax</th> |
| <th>Arguments</th> |
| </tr> |
| </thead> |
| <tbody> |
| <tr> |
| <td>25 3rc</td> |
| <td>filled-new-array/range {vCCCC .. vNNNN}, type@BBBB</td> |
| <td><code>A:</code> array size and argument word count (8 bits)<br/> |
| <code>B:</code> type index (16 bits)<br/> |
| <code>C:</code> first argument register (16 bits)<br/> |
| <code>N = A + C - 1</code></td> |
| </tr> |
| </tbody> |
| </table> |
| |
| <h2>Constraints</h2> |
| |
| <ul> |
| <li> |
| vN must be a valid register index in the current stack frame (this means |
| everything below vN is valid, too). |
| </li> |
| <li> |
| For all values I in the interval [C .. N] the following must hold: |
| <ul> |
| <li> |
| vI must not be part of a register pair |
| </li> |
| <li> |
| If the array type is a simple type, vI must be a simple type, too. |
| </li> |
| <li> |
| If the array type is a reference type, vI must be a reference type, too. |
| </li> |
| </ul> |
| </li> |
| <li> |
| B must be a valid index into the type pool. |
| </li> |
| <li> |
| The type denoted by B must be an array type. |
| </li> |
| <li> |
| The element size of the type denoted by B must be no larger than 32 bits. |
| </li> |
| </ul> |
| |
| <h2>Behavior</h2> |
| |
| <ul> |
| <li> |
| An attempt is made to get a reference to the type T the name of which is |
| contained in type pool entry B. |
| </li> |
| <li> |
| If T has not been loaded and resolved before, it is being loaded and |
| resolved. All exceptions that are possible during class loading can occur at |
| this point. |
| </li> |
| <li> |
| An attempt is made to create a new instance J of type T and length vA. All |
| exceptions that are possible during instantiation can occur at this point. |
| </li> |
| <li> |
| The elements of R are filled according to the following rules: |
| <ul> |
| <li> |
| J[0] = vC |
| </li> |
| <li> |
| J[1] = v(C+1) |
| </li> |
| <li> |
| ... |
| </li> |
| <li> |
| J[vA] = vN |
| </li> |
| </ul> |
| </li> |
| <li> |
| No reference to J is stored in any register. Instead, J can be accessed by a |
| move-result-object instruction immediately following this filled-new-array |
| instruction. |
| </li> |
| </ul> |
| |
| <h2>Exceptions</h2> |
| |
| <ul> |
| <li> |
| NegativeArraySizeException if vA < 0 |
| </li> |
| </ul> |
