| 35 | * @summary StepTest starts at a method named "go()" in the debuggee and |
| 36 | * repetitively steps. It will do a step into until the maximum |
| 37 | * stack depth (specified on command line) is reached. At that point |
| 38 | * it begins to step over. Step granularity is determined from the |
| 39 | * command line. Stepping is repeated the until the end of go() is reached |
| 40 | * or until the requested number of steps (specified on command line) |
| 41 | * is performed. An exception is thrown if the requested number of |
| 42 | * steps does not result in the debuggee's location being at the end of |
| 43 | * go(). |
| 44 | * This test is sensitive to the line number info generated by the compiler |
| 45 | * for the debuggee files- MethodCalls.java, ... |
| 46 | * See LineNumberInfo.java for more info. |

| 66 | * The workaround column contains the expected number of steps |
| 67 | * on non IA64 VMs. These VMs get it wrong and should be |
| 68 | * fixed (4787861). When they are fixed, this test should be fixed |
| 69 | * to remove this workaround. |
| 70 | * The C interpreter in the IA64 VM handles catches differently |
| 71 | * than the asm interpreter. For the construct |
| 72 | * line statement |
| 73 | * ----------------- |
| 74 | * 68 catch (Exception ee) { |
| 75 | * 69 System.out.println(...) |
| 76 | * javac outputs the store into ee as being on line 68 and the |
| 77 | * start of the println on line 69. The handler starts with the |
| 78 | * store into ee, ie, line 68. When a step is done under the |
| 79 | * associated try and an exception is encountered, |
| 80 | * the IA64 VM stops at line 68 while the other VM stops at |
| 81 | * line 69. It seems that the IA64 VM is correct. |
| 82 | * But, it is too late to fix the other VM for Mantis, |
| 83 | * so this test is being made so that it will pass both VMs. |
| 84 | * For each catch that occurs, an extra step is needed |
| 85 | * on the IA64 VM. This only occurs in MethodCallsReflection |
| 86 | * which contains 6 of these catches (so we have to do 6 |
| 87 | * extra steps to make it pass) and in ControlFlow which |
| 88 | * does it once. |
