# Gyp file for opts projects { 'targets': [ # 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. { 'target_name': 'opts', 'product_name': 'skia_opts', 'type': 'static_library', 'standalone_static_library': 1, 'dependencies': [ 'core.gyp:*', 'effects.gyp:*' ], 'include_dirs': [ '../src/core', '../src/opts', ], 'conditions': [ [ 'skia_arch_type == "x86" and skia_os != "ios"', { 'conditions': [ [ 'skia_os in ["linux", "freebsd", "openbsd", "solaris", "nacl", "chromeos", "android"]', { 'cflags': [ '-msse2', ], }], ], 'include_dirs': [ '../include/utils', ], 'dependencies': [ 'opts_ssse3', ], 'sources': [ '../src/opts/opts_check_SSE2.cpp', '../src/opts/SkBitmapProcState_opts_SSE2.cpp', '../src/opts/SkBitmapFilter_opts_SSE2.cpp', '../src/opts/SkBlitRow_opts_SSE2.cpp', '../src/opts/SkBlitRect_opts_SSE2.cpp', '../src/opts/SkBlurImage_opts_SSE2.cpp', '../src/opts/SkMorphology_opts_SSE2.cpp', '../src/opts/SkUtils_opts_SSE2.cpp', '../src/opts/SkXfermode_opts_none.cpp', ], }], [ 'skia_arch_type == "arm" and arm_version >= 7', { # The assembly uses the frame pointer register (r7 in Thumb/r11 in # ARM), the compiler doesn't like that.
