New Revision: 269390
URL: http://svnweb.freebsd.org/changeset/base/269390

Log:
  Fix unwind-info errors in our hand-written arm assembler code.
  
  We have functions nested within functions, and places where we start a
  function then never end it, we just jump to the middle of something else.
  We tried to express this with nested ENTRY()/END() macros (which result
  in .fnstart and .fnend directives), but it turns out there's no way to
  express that nesting in ARM EHABI unwind info, and newer tools treat
  multiple .fnstart directives without an intervening .fnend as an error.
  
  These changes introduce two new macros, EENTRY() and EEND().  EENTRY()
  creates a global label you can call/jump to just like ENTRY(), but it
  doesn't emit a .fnstart.  EEND() is a no-op that just documents the
  conceptual endpoint that matches up with the same-named EENTRY().
  
  This is based on patches submitted by Stepan Dyatkovskiy, but I made some
  changes and added the EEND() stuff, so blame any problems on me.
