| 1253 | // memory mapped so we could predict where its contents were based |
| 1254 | // on the file size. Now that it is an ELF file, we need to inspect |

| 1256 | // where the oat header is located within. ImageWriter's |
| 1257 | // PatchOatCodeAndMethods uses the PatchInformation from the |
| 1258 | // Compiler to touch up absolute references in the oat file. |
| 1259 | // |
| 1260 | // 3. We fixup the ELF program headers so that dlopen will try to |
| 1261 | // load the .so at the desired location at runtime by offsetting the |
