Bug ID: 116595
Summary: default-initialization of vfloat32m1x4_t causes ICE
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Target: riscv
Take this C++:
```
#include <riscv_vector.h>
void transpose4x4_ps()
{
vfloat32m1x4_t _r = vfloat32m1x4_t();
}
```
This ICEs with:
<source>: In function 'void transpose4x4_ps()':
<source>:6:20: internal compiler error: in to_constant, at poly-int.h:592
6 | vfloat32m1x4_t _r = vfloat32m1x4_t();
| ^~
I am not sure this is valid or not.
It also ICEs with clang.

The same ICE happens with SVE:
```
#include <arm_sve.h>
void transpose4x4_ps()
{
svfloat32x4_t _r = svfloat32x4_t();
}
```

Hmmm, it's not well defined in the rvv intrinsic doc, but I suppose this should
at least work (compile-able) without crash, also it seems works fine on GCC 14

It might be a checking assert I didn't check.

Yes it is a checking assert:
gcc_checking_assert (is_constant ());

GCC 14 with enable checking will trigger that as well, thanks for remind that
detail, I forgot trunk will enable checking by default but release branch isn't
