| // This test verifies that loading an ELF file from memory works and the new |
| // features that were added when loading from memory work like: |
| // - Loading the .dynamic section from the PT_DYNAMIC since ELF files loaded |
| // from memory don't have the section headers available. |
| // This test will make a simple executable that: |
| // - links against libc |
| // - runs and stops at a breakpoint |
| // - create a memory ELF file |
| // - verify that "image dump objfile" will dump the dynamic section of the |
| // memory elf file and find the .dynamic string table. |
