Seems to work fine with explicit '-mincoming-stack-boundary=2' on the command
line, even though it should make no difference for the 32-bit MinGW target.

I fixed this issue:

Hope it will be landed into trunk and backport to GCC-13 soon.
Thanks.

Meanwhile, the float reduction for FP16 is not well supported for both the
ZVE64 and ZVE32. We will try to fix them together with this bug.
