Ben Kietzman commented on ARROW-15678:
--------------------------------------
[~apitrou] The most robust solution I can think of is to avoid linking between
objects with differing instruction sets altogether. We'd have something like
{code}
$ nm libarrow_compute_avx2.so | grep DefLevelsBitmapSimd
0000000000404ff0 t DefLevelsBitmapSimd
{code}
That library would be acquired with {{dlopen(path,
RTLD_LOCAL)/LoadLibrary(path)}} which would guarantee that any functions like
{{FirstTimeBitmapWriter::*}} which might have been recompiled with illegal
instructions are not available outside {{libarrow_compute_avx2.so}}.
