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