Regression in libyuv::I420Psnr on Android ARM64 #502

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Get a WebRTC checkout using 'fetch webrtc'
2. Create a local branch and apply https://codereview.webrtc.org/1399453002:
git checkout master
git checkout -b test
git cl patch 1399453002
3. Compile for ARM64:
export GYP_CROSSCOMPILE=1
export GYP_DEFINES="OS=android target_arch=arm64 component=static_library 
dcheck_always_on=1 fastbuild=1"
gclient runhooks
ninja -C out/Release common_video_unittests_apk

4. Run common_video_unittests on Android with an ARM64 device, e.g. Nexus 9:
webrtc/build/android/test_runner.py gtest -s common_video_unittests --verbose 
--release 
--isolate_file_path=webrtc/common_video/common_video_unittests.isolate 
--gtest_filter=TestLibYuv.ConvertTest

What is the expected output? What do you see instead?

The test should pass. Instead if fails like this:

http://build.chromium.org/p/tryserver.webrtc/builders/android_arm64_rel/builds/2
867/steps/common_video_unittests/logs/stdio)

I also reproduced with my local checkout using the instructions above.

What version of the product are you using? On what operating system?
Android ARM64

Please provide any additional information below.

I'm reverting the libyuv roll in Chrome 
https://codereview.chromium.org/1389233002 for now, to unblock WebRTC from 
rolling forward.

Instructions above didnt work on a new linux machine.  Looks like first step 
should be
1. fetch webrtc_android

but I did get the webrtc tests to run... without the patch, they pass.

Is it possible to adapt this to run libyuv_unittest?

The old code used hard coded constants for BT.601

// TODO(fbarchard): replace movi with constants from struct.
#define YUVTORGB_SETUP                                                         \
    "ld1r       {v24.8h}, [%[kUVBiasBGR]], #2  \n"                             \
    "ld1r       {v25.8h}, [%[kUVBiasBGR]], #2  \n"                             \
    "ld1r       {v26.8h}, [%[kUVBiasBGR]]      \n"                             \
    "ld1r       {v31.4s}, [%[kYToRgb]]         \n"                             \
    "movi       v27.8h, #128                   \n"                             \
    "movi       v28.8h, #102                   \n"                             \
    "movi       v29.8h, #25                    \n"                             \
    "movi       v30.8h, #52                    \n"

If I change back to that, the webrtc test passes.
