| 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. | |
| 24 | |
| 25 # For about the same reason, we need to compile the ARM opts files | |
| 26 # separately as well. | |
