New Revision: 272519
URL: https://svnweb.freebsd.org/changeset/base/272519

Log:
  Add movw and movt relocations to the list of relocations against function
  names that must nnot be adjusted. This fixes a bug where code such as:
  movw r2, :lower16:symbol
  movt r2, :upper16:symbol
  
  It is common for clang to generate such code when targeting armv7.
