+Subject: [PATCH] chromium: aarch64 skia build fix
+
+Upstream-Status: Inappropriate
+
+GCC (tested rocko's 7.3.0) cannot find these intrinsics and the build fails:
+
+../../third_party/skia/src/opts/SkRasterPipeline_opts.h: In function 'neon::F neon::from_half(neon::U16)':
+../../third_party/skia/src/opts/SkRasterPipeline_opts.h:657:26: error: cannot convert 'neon::U16 {aka short unsigned int}' to 'float16x4_    t {aka __vector(4) __    fp16}' for argument '1' to '
+float32x4_t vcvt_f32_f16(float16x4_t)'
+     return vcvt_f32_f16(h);
+                          ^
+../../third_party/skia/src/opts/SkRasterPipeline_opts.h: In function 'neon::U16 neon::to_half(neon::F)':
+../../third_party/skia/src/opts/SkRasterPipeline_opts.h:677:26: error: cannot convert 'neon::F {aka float}' to 'float32x4_t {aka __vector    (4) float}' for argum    ent '1' to 'float16x4_t vcvt
+_f16_f32(float32x4_t)'
+     return vcvt_f16_f32(f);
+                          ^
+
+Upstream seems to have had similar issues according to
+https://skia-review.googlesource.com/c/skia/+/84222, but there is no fix at the
+moment.
