Committed as obvious. FWIW, I'm on the side that emitting
the warning when the reason is just that it's the default
layout, is bad. A discussion took place years ago when the

The problem here is after r13-4748-g2a27ae32fabf85, in some
cases we were calling inform without a corresponding warning.
This changes the logic such that we only cause that to happen
if there was a warning happened before hand.

Previously, if the analyzer saw a call to a non-pure and non-const
built-in function that it didn't have explicit knowledge of the behavior
of, it would fall back to assuming that the builtin could have arbitrary
behavior, similar to a function defined outside of the current TU.

Thanks all for so much valuable and helpful materials.
As I understand (Please help to correct me if any mistake.), for the VNx*BI
(aka, 1, 2, 4, 8, 16, 32, 64),
the precision and mode size need to be adjusted as below.
Precision size [1, 2, 4, 8, 16, 32, 64]
Mode size [1, 1, 1, 1, 2, 4, 8]

Let's me first introduce RVV load/store basics and stack allocation.
For scalable vector memory allocation, we allocate memory according to machine
vector-length.
To get this CPU vector-length value (runtime invariant but compile time
unknown), we have an instruction call csrr vlenb.

When combining -g1 with -flto we run into the DIE location annotation
machinery for globals calling dwarf2out_late_global_decl but not
having any early generated DIE for function scope statics. In
this process we'd generate a limbo DIE since also the function scope

I am not very familiar with the memory pattern, maybe juzhe can provide more
information or correct me if anything is misleading.
The different precision try to resolve the below bugs, the second vlm(with
different size of load bytes compared to first one)
