| 12 // GDB support. | |
| 13 // | |
| 14 // That is: | |
| 15 // - js/src/gdb/mozilla holds the actual GDB SpiderMonkey support code. | |
| 16 // - Each '.py' file in js/src/gdb/tests is a unit test for the above. | |
| 17 // - Each '.cpp' file in js/src/gdb/tests is C++ code for one of the unit tests | |
| 18 // to run. | |
| 19 // | |
| 20 // (So the .cpp files are two steps removed from being anything one would | |
| 21 // actually run.) | |
