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).
