| # 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. |
