| // * Test class linker falls back to unquickened dex for MultiDexNoOat |
| // * Test using secondary isa |
| // * Test for status of oat while oat is being generated (how?) |
| // * Test case where 32 and 64 bit boot class paths differ, |
| // and we ask IsInBootClassPath for a class in exactly one of the 32 or |
| // 64 bit boot class paths. |
| // * Test unexpected scenarios (?): |
| // - Dex is stripped, don't have odex. |
| // - Oat file corrupted after status check, before reload unexecutable |
| // because it's unrelocated and no dex2oat |
