@Lunderberg If I make this change,
```
- // decorate the array type.
- this->Decorate(spv::OpDecorate, arr_type, spv::DecorationArrayStride,
nbytes);
+ if (!interface_block) {
+ // decorate the array type.
+ this->Decorate(spv::OpDecorate, arr_type, spv::DecorationArrayStride,
nbytes);
+ }
```
I get this error
```

TVMError:

Check failed: res == SPV_SUCCESS (-10 vs. 0) : index=33 error:Structure
id 10 decorated as Block for variable in StorageBuffer storage class must
follow standard storage
buffer layout rules: member 0 contains an array with stride 0, but with an
element size of 4
%_struct_10 = OpTypeStruct %_runtimearr_float
```
Looking at the spec sentence, I wonder what exactly ` array that contains a
structure` means. Isn't array itself a structure? What does it mean to have an
array that contains `Block`?
