alloc2 used unnecessarily
The bfd_alloc2 series of functions were invented to handle cases where
nmemb * size can overflow. This patch changes some places where the
calculation can't overflow.
* elf.c (bfd_section_from_shdr): Use bfd_zalloc rather than
bfd_zalloc2.
(assign_section_numbers): Likewise.
(elf_map_symbols): Likewise, and bfd_alloc rather than bfd_alloc2.
(_bfd_elf_map_sections_to_segments): Use bfd_malloc rather than
bfd_malloc2, size_t amt, and unsigned tls_count.
(rewrite_elf_program_header): Use bfd_malloc and size_t amt.
* elflink.c (elf_create_symbuf): Use bfd_malloc.
(elf_output_implib): Use bfd_alloc.
