    lib/msun/src         e_expf.c 
  Log:
  Use double arithmetic instead of simulating it with two floats.  This
  results in a performance gain on the order of 10% for amd64 (sledge),
  ia64 (pluto1), i386+SSE (Pentium 4), and sparc64 (panther), and a
  negligible improvement for i386 without SSE.  (The i386 port still
  uses the hardware instruction, though.)
