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. 27 { 28 'target_name': 'skia_opts', 29 'type': 'static_library', 30 'includes': [ 31 'skia_common.gypi', 32 ], 33 'include_dirs': [ 34 '../third_party/skia/include/core', 35 '../third_party/skia/src/core', 36 '../third_party/skia/src/opts', 37 ], 38 'conditions': [ 39 [ 'os_posix == 1 and OS != "mac" and OS != "android" and \ 40 target_arch != "arm" and target_arch != "mipsel"', { 41 'cflags': [ 42 '-msse2', 43 ], 44 }], 45 [ 'target_arch != "arm" and target_arch != "mipsel"', { 46 'sources': [ 47 '../third_party/skia/src/opts/SkBitmapProcState_opts_SSE2.cpp', 48 '../third_party/skia/src/opts/SkBlitRect_opts_SSE2.cpp', 49 '../third_party/skia/src/opts/SkBlitRow_opts_SSE2.cpp', 50 '../third_party/skia/src/opts/SkUtils_opts_SSE2.cpp', 51 '../third_party/skia/src/opts/SkXfermode_opts_none.cpp', 52 '../third_party/skia/src/opts/SkBitmapFilter_opts_SSE2.cpp', 53 '../third_party/skia/src/opts/SkMorphology_opts_SSE2.cpp', 54 '../third_party/skia/src/opts/SkBlurImage_opts_SSE2.cpp', 55 ], 56 'dependencies': [ 57 'skia_opts_ssse3', 58 ], 59 }], 60 [ 'target_arch == "arm"', { 61 'conditions': [ 62 [ 'arm_version >= 7 and arm_neon == 1', { 63 'defines': [ 64 '__ARM_HAVE_NEON', 65 ], 66 }], 67 [ 'arm_version >= 7 and arm_neon_optional == 1', { 68 'defines': [ 69 '__ARM_HAVE_OPTIONAL_NEON_SUPPORT', 70 ], 71 }], 72 [ 'arm_version >= 7 and (arm_neon == 1 or arm_neon_optional == 1)', { 73 'cflags': [ 74 # The neon assembly contains conditional instructions which 75 # aren't enclosed in an IT block.
