Hmm, the .S file is build only if HAVE_NEON, but it contains both neon & v6 no neon code (if i understand it correctly).<br><br>try to remove if HAVE_NEON in Modules.am, the correct code should be detected at runtime.<br>

Hello,<br>
<br>
Since revision 95eb79718122dcc8f586cbbd10f8b0<u></u>feb2fa4fa4 ("deinterlace: rewrite ARM optimizations for 8-bits merge"), the VLC for Android build has been broken [1][2]:<br>

<br>
I was able to consistently get the error with a fresh clone of vlc.git, including everything up to d12a67f403d9cd91c4c84d7681ed73<u></u>6936fbf71f ("deinterlace: fix build"). Reverting only 95eb79718122dcc8f586cbbd10f8b0<u></u>feb2fa4fa4 on top of master seems to work for me. Any thoughts or actions?<br>
