  11     # gcc lameness is that, in order to compile SSE2 intrinsics code, it
  12     # must be passed the -msse2 flag.  However, with this flag, it may
  13     # emit SSE2 instructions even for scalar code, such as the CPUID
  14     # test used to test for the presence of SSE2.  So that, and all other
  15     # code must be compiled *without* -msse2.  The gyp lameness is that it
  16     # does not allow file-specific CFLAGS, so we must create this extra
  17     # target for those files to be compiled with -msse2.
  18     #
  19     # This is actually only a problem on 32-bit Linux (all Intel Macs have
  20     # SSE2, Linux x86_64 has SSE2 by definition, and MSC will happily emit
  21     # SSE2 from instrinsics, which generating plain ol' 386 for everything
  22     # else).  However, to keep the .gyp file simple and avoid platform-specific
  23     # build breakage, we do this on all platforms.
