// REQUIRES: system-linux, native

// 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.
