Author: lwhsu (ports committer) Date: Fri Jan 13 19:22:22 2017 New Revision: 312082 URL: https://svnweb.freebsd.org/changeset/base/312082 Log: MFC r311881: Replace using of objdump with elfdump In-tree objdump is too old to dump new ELF headers. But for example if we use: `make CROSS_TOOLCHAIN=riscv64-gcc TARGET_ARCH=riscv64` and do not specify CROSS_BINUTILS_PREFIX in env, embed_mfs.sh cannot find the correct objdump. This patch just replaces using of objdump with elfdump to collect needed information. Later we may also put an ELFDUMP in CROSSENV and use it in embed_mfs.sh .
