[PATCH 8/9] binutils: add support for eBPF
- From: "Jose E. Marchesi" <jose dot marchesi at oracle dot com>
- To: binutils at sourceware dot org
- Date: Mon, 20 May 2019 18:45:25 +0200
- Subject: [PATCH 8/9] binutils: add support for eBPF
- References: <20190520164526.13491-1-jose.marchesi@oracle.com>
This patch adds support for ELF64 eBPF to readelf, and fixes a `nm'
test to run properly in bpf-*-* targets.
binutils/ChangeLog:
2019-05-20 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.
