Subject: [PATCH 0/3] objtool: add support for >64k sections
Date: Tue, 21 Apr 2020 11:07:21 -0700 [thread overview]
Message-ID: <20200421180724.245410-1-samitolvanen@google.com> (raw)
This series fixes objtool for binaries with >64k sections, and
includes optimizations to reduce the runtime for a binary with
~130k sections from >15 minutes to ~4 seconds.
Sami Tolvanen (3):
objtool: use gelf_getsymshndx to handle >64k sections
objtool: optimize insn_hash for split sections
objtool: optimize add_dead_ends for split sections
