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.
