So this test passes on ARM for me on a Nexus 7..

I tried on a Nexus 5x as well (and I did in fact comment out the #if to be clear) and it passes on that also.

https://codereview.chromium.org/2504583003/ does what I did locally for bots.

It does fail on the bot. https://build.chromium.org/p/tryserver.chromium.android/builders/android_n5x_swarming_rel/builds/68378/steps/gfx_unittests%20%28with%20patch%29%20on%20Android/logs/QuadTest.ContainsPoint

What is happen?

Nico, since you were doing this, do u have any ideas or who I should ask questions to?

I tried using target_cpu = "arm64" but that fails to install on nexus7 so guess not.

From the trybot:

Writing """\
dcheck_always_on = true
ffmpeg_branding = "Chrome"
goma_dir = "/b/c/cipd/goma"
is_component_build = false
is_debug = false
proprietary_codecs = true
symbol_level = 1
target_cpu = "arm64"
target_os = "android"
use_goma = true
""" to /b/c/

I'd try in that config on a n5x.

Ah ok ya "target_cpu = "arm64"" on a n5x does reproduce this.

Fix QuadF::ContainsPoint and gfx::CrossProduct on arm64

These methods require the use of doubles to not give incorrect
answers. Tests were failing on arm64 due to precision mistakes
with floats.
