Libpng-1.6.25 adds MIPS-MSA support.  It's not very well tested yet.

libpng-1.6.25 patch from bug #1299590 must be applied first
Does the "try" system have a MIPS platform to test this on?

It does not.

Heiher might be able to help test it.

I've released pngcrush-1.8.6 today which has the same MIPS support, but I haven't tested it.  There hasn't been any feedback to the png developers.  Maybe it'd be simpler to try pngcrush first.

Sorry for later.

I have not a MIPS processor that supported MSA ASE. :( Rankov might be able to help. :)

You can use QEMU (trunk) to test MSA.
Pass "-cpu P5600" to emulate the core with MSA support.
Clearing needinfo since Petar responded.

Update patch to fix bit rot in media/libpng/moz.build due to checkin of libpng-1.6.29.
