Dear Maintainer,
At the moment, the library fail to build on powerpc, because it is an
unknown architecture. I gave porting the library a go, and got it
building, but the tests are segfaulting. Note, I do not really know the
inner workings of powerpc well enough to set up proper definitions, so
the values are copied from mips and endianness changed from little to
big. I also tried to base it on powerpc64le, but this crashed too.
In any case, I hope this can be a starting point for someone else
looking at powerpc porting.
