binutils: add support for eBPF
This patch adds support for ELF64 eBPF to readelf, and fixes a `nm' test to run properly in bpf-*-* targets. binutils/ChangeLog: 2019-05-23 Jose E. Marchesi <jose.marchesi@oracle.com> * readelf.c: Include elf/bpf.h. (guess_is_rela): Hanle EM_BPF. (dump_relocations): Likewise. (is_32bit_abs_reloc): Likewise. * testsuite/binutils-all/nm.exp: Add bpf-*-* to the list of ELF targets.
