lebedev.ri added a comment.
I'm a little bit lost with all this AMX stuff.
Could you please explain in normal human words, what does `__tile_loadd()` do?
I.e. given
void wrapper(__tile& dst, const void *base, int stride) {
_tile_loadd(dst, const void *base, int stride);
}
which bytes from `base` will be loaded?
================

+// RUN: %clang_cc1 %s -O2 -ffreestanding -triple=x86_64-unknown-unknown
-target-feature +avx512f -target-feature +amx-int8 \
+// RUN: -target-feature +amx-bf16 -emit-llvm -o - -Werror -pedantic |
FileCheck %s --check-prefixes=CHECK
----------------
Please don't use llvm optimizations in clang tests.

+#include <immintrin.h>

----------------
The tests should be hermetic.
Which `immintrin.h` is being used there?
Hopefully the one from clang, not the one from system?
