> I'm not sure if there's a problem with the test matrix verifier tests or another difference, but I *think* the matrix verifier tests check multiple errors in a single file for example: https://github.com/llvm/llvm-project/blob/main/llvm/test/Verifier/matrix-intrinsics.ll
I tested llvm/test/Verifier/matrix-intrinsics.ll. Yes this case is able to be grouped in a single file, but it is not the same to x86_amx test case. 


```
[llvm]$ cat test/Verifier/x86_amx.ll
; RUN: not llvm-as %s -o /dev/null 2>&1 | FileCheck %s

define dso_local void @f() {
entry:
  %a.addr = alloca <2 x x86_amx>, align 4
  ret void
}

; CHECK: invalid vector element type

define void @f(x86_amx %A, x86_amx %B) {
entry:
  alloca x86_amx
; CHECK: invalid type for alloca
  ret void
}
[llvm]$ llvm-as test/Verifier/x86_amx.ll
llvm-as: test/Verifier/x86_amx.ll:5:25: error: invalid vector element type
  %a.addr = alloca <2 x x86_amx>, align 4
                        ^
[llvm]$
