New Revision: 340972
URL: https://svnweb.freebsd.org/changeset/base/340972

Log:
  llvm-objdump: initial man page
  
  Based on llvm-objdump's online documentation and usage information.
  This serves as a starting point; additional detail and cleanup still
  required.
  
  Also being submitted upstream in LLVM review D54864.  I expect to use
  this bespoke copy while we have LLVM 6.0 or 7.0 in FreeBSD; when we
  update to LLVM 8.0 it should be upstream and we will switch to it.
