This test uses a simple custom elf loader, implemented in gdb.base/sym-file-loader.h|c. This loader doesn't have a dlclose-like function today, but I'll need one. But, I found that the guts of the loader are exposed too much to the client, making the interface more complicated than necessary. It's simpler if the loader just exports a few dlopen/dlsym -style functions. That's what this patch does. Tested on x86_86 Fedora 17, native and gdbserver. gdb/testsuite/ 2014-04-15 Pedro Alves <palves@redhat.com> * gdb.base/sym-file-loader.h: Move inclusion of <inttypes.h>, <ansidecl.h>, <elf/common.h> and <elf/external.h> to sym-file-loader.c. (Elf_External_Phdr, Elf_External_Ehdr, Elf_External_Shdr) (Elf_External_Sym, Elf_Addr, GET, GETADDR, struct segment): Move to sym-file-loader.c. (struct library): Forward declare. (load_shlib, lookup_function): Change prototypes. (find_shstrtab, find_strtab, find_shdr, find_symtab) (translate_offset): Remove declarations. (get_text_addr): New declaration. * gdb.base/sym-file-loader.c: Move inclusion of <inttypes.h>, <ansidecl.h>, <elf/common.h> and <elf/external.h> here from sym-file-loader.h. (Elf_External_Phdr, Elf_External_Ehdr, Elf_External_Shdr) (Elf_External_Sym, Elf_Addr, GET, GETADDR, struct segment): Move here from sym-file-loader.h. (struct library): New structure. (load_shlib, lookup_function): Change prototypes and adjust to work with a struct library. (find_shstrtab, find_strtab, find_shdr, find_symtab) (translate_offset): Make static. (get_text_addr): New function. * gdb.base/sym-file-main.c (main): Adjust to new loader interface.
