Use containers to avoid cleanups
This patch introduces the use of various containers -- std::vector,
std::string, or gdb::byte_vector -- in several spots in gdb that were
using xmalloc and a cleanup.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* valops.c (search_struct_method): Use gdb::byte_vector.
* valarith.c (value_concat): Use std::vector.
* target.c (memory_xfer_partial): Use gdb::byte_vector.
(simple_search_memory): Likewise.
* printcmd.c (find_string_backward): Use gdb::byte_vector.
* mi/mi-main.c (mi_cmd_data_write_memory): Use gdb::byte_vector.
* gcore.c (gcore_copy_callback): Use gdb::byte_vector.
* elfread.c (elf_rel_plt_read): Use std::string.
* cp-valprint.c (cp_print_value): Use gdb::byte_vector.
* cli/cli-dump.c (restore_section_callback): Use
gdb::byte_vector.
