3 # Due to an unfortunate intersection of lameness between gcc and gyp,
4 # we have to build the *_SSE2.cpp files in a separate target. The
5 # gcc lameness is that, in order to compile SSE2 intrinsics code, it
6 # must be passed the -msse2 flag. However, with this flag, it may
7 # emit SSE2 instructions even for scalar code, such as the CPUID
8 # test used to test for the presence of SSE2. So that, and all other
9 # code must be compiled *without* -msse2. The gyp lameness is that it
10 # does not allow file-specific CFLAGS, so we must create this extra
11 # target for those files to be compiled with -msse2.
13 # This is actually only a problem on 32-bit Linux (all Intel Macs have
14 # SSE2, Linux x86_64 has SSE2 by definition, and MSC will happily emit
15 # SSE2 from instrinsics, while generating plain ol' 386 for everything
16 # else). However, to keep the .gyp file simple and avoid platform-specific
17 # build breakage, we do this on all platforms.
19 # For about the same reason, we need to compile the ARM opts files
