Hi Martin,
Is there any progress for this patch, should I resend it to the mailing list
again?
When I posted the updated version of the patch, the patchwork test runners
noticed that this patch causes test failures on Loongarch. So modern
versions of GCC still do have vectorization bugs, at least on some
architectures.
I'm unsure if we should allow it everywhere, and just single out loongarch
as a case where it is known broken, or if we should only let GCC enable it
on the major architectures that we've tested.
In either case, we should isolate the compiler bugs on loongarch and
report them, as well, so that they have a chance of getting the
vectorization to work properly.
