New Revision: 194301
URL: http://svn.freebsd.org/changeset/base/194301

Log:
  MFC r181997 by kib:
  
    Add -fno-omit-frame-pointer to CFLAGS used to compile crt1.c on amd64.
  
    For gcc' __builtin_frame_address() to work, all call frames need to save
    frame pointer. In particular, this is important for the upper frame that
    should terminate the chain.
