9 # Due to an unfortunate intersection of lameness between gcc and gyp,
10 # we have to build the *_SSE2.cpp files in a separate target. The
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.
25 # For about the same reason, we need to compile the ARM opts files
26 # separately as well.
