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
