| // REQUIRES: system-linux, native, python | |
| // 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. | |
