1// REQUIRES: system-linux, native, python 2 3// This test verifies that loading an ELF file from memory works and the new 4// features that were added when loading from memory work like: 5// - Loading the .dynamic section from the PT_DYNAMIC since ELF files loaded 6// from memory don't have the section headers available. 7// This test will make a simple executable that: 8// - links against libc 9// - runs and stops at a breakpoint 10// - create a memory ELF file 11// - verify that "image dump objfile" will dump the dynamic section of the 12// memory elf file and find the .dynamic string table. 13 14// RUN: %clang_host %p/Inputs/memory-elf.cpp -g -O0 -o %t 15 16// RUN: %lldb %t -b \ 17// RUN: -o "b main" \ 18// RUN: -o "run" \ 19// RUN: -o "script real_module = lldb.target.module[0]" \ 20// RUN: -o "script base_addr = real_module.GetObjectFileHeaderAddress().GetLoadAddress(lldb.target)" \ 21// RUN: -o "script mem_module = lldb.SBModule(lldb.process, base_addr)" \ 22// RUN: -o "script target2 = lldb.debugger.CreateTarget('')" \ 23// RUN: -o "script target2.AddModule(mem_module)" \ 24// RUN: -o "target select 1" \ 25// RUN: -o "image dump objfile" \ 26// RUN: | FileCheck %s --check-prefix=MAIN --dump-input=always 27// MAIN: (lldb) image dump objfile 28// MAIN: Dumping headers for 1 module(s). 29// MAIN: ObjectFileELF, file = '', arch = {{.*, addr = 0x[0-9a-f]+}} 30// MAIN: ELF Header 31 32// Make sure we find the program headers and see a PT_DYNAMIC entry. 33// MAIN: Program Headers 34// MAIN: ] PT_DYNAMIC 35 36// Make sure we see some sections created from the program headers 37// MAIN: SectID 38// MAIN: PT_LOAD[0] 39 40// Ensure we find some dependent modules as won't find these if we aren't able 41// to load the .dynamic section from the PT_DYNAMIC program header. 42// MAIN: Dependent Modules: 43 44// Check for the .dynamic dump and ensure we find all dynamic entries that are 45// required to be there and needed to get the .dynstr section and the symbol 46// table, and the DT_DEBUG entry to find the list of shared libraries. 47// MAIN: .dynamic: 48// Make sure we found the .dynstr section by checking for valid strings after NEEDED 49// MAIN-DAG: NEEDED {{0x[0-9a-f]+ ".*libc.*"}} 50// MAIN-DAG: STRTAB {{0x[0-9a-f]+}} 51// MAIN-DAG: SYMTAB {{0x[0-9a-f]+}} 52// MAIN-DAG: STRSZ {{0x[0-9a-f]+}} 53// MAIN-DAG: SYMENT {{0x[0-9a-f]+}} 54// MAIN-DAG: DEBUG {{0x[0-9a-f]+}} 55// MAIN: NULL {{0x[0-9a-f]+}} 56
