# 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, while 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.
