  42 # Currently, the only differences between hwcap1 and hwcap2 are the kernel entry
  43 # method (hwcap1 uses "sysenter" and hwcap2 uses "syscall"), and sse2 vs sse
  44 # in the optimized assembler routines. Neither difference merits splitting the
  45 # source. So for now, build libc_hwcap2 with the optimized sources for
  46 # libc_hwcap1.
