Unfortunately, it is not so easy. The first version of this patchset
(this here) forgot to update the definitions of several loongarch
functions, leading to lots of red on patchwork. The second version fixed
the compilation error, but forgot some constifications due to
unfortunate oversights. For the third version, I wanted to actually
compile loongarch instead of just staring at the code; but the
GCC-cross-compiler does not seem to support lsx and lasx (and looking at
the loongarch-code in GCC makes me believe that they are just not
supported (yet)). Therefore I resorted to creating dummy-functions for
all the __lasx_* and __lsx_* functions (they show no more
const-warnings). I wanted to let the FATE-loongarch-box test this once
more (and tell me whether there are still any issues left), yet this box
is no longer active since a few days (for reasons unknown). Can you
compile the lsx and lasx code (after all, you committed all the
loongarch code)?
