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

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