    sys/ia64/ia64        trap.c 
    sys/ia64/include     _regset.h 
  Log:
  Remove __aligned(16) from the definition of struct _ia64_fpreg. It's
  a non-standard construct. Instead, redefine struct _ia64_fpreg as a
  union and put a long double in it. On ia64 and for LP64, this is
  defined by the ABI to have 16-byte alignment. For ILP32 a long double
  has 4-byte alignment, but we don't support ILP32.
  
  Note that the in-memory image of a long double does not match the in-
  memory image of spilled FP registers. This means that one cannot use
  the fpr_flt field to interpet the bits. For this reason we continue
  to use an aggregate type.
