Hi Juzhe,
Stage 3 will close today and there are still some patches that
haven't been reviewed left.
So is it possible to get xtheadvector merged in GCC-14?
We emailed Kito regarding this, but haven't got any reply yet.

\ No newline at end of file
Each file needs newline.
I am not able to review arch stuff. This needs kito.
Besides, Andrew Pinski want us defer theadvector to GCC-15.
I have no strong opinion here.

Hi Juzhe,
So is the following patch that this patch relies on OK to commit?

This is Ok from my side.
But before commit this patch, I think we need this patch first:
https://gcc.gnu.org/pipermail/gcc-patches/2023-December/641533.html
I will be back to work so I will take a look at other patches today.

Just a formatting nit. The GNU standards break lines before the
operator, not after. So
if (TARGET_XTHEADVECTOR
&& current_output_insn != NULL
&& p[0] == 'v')
Note that current_output_insn is "extern rtx_insn *", so use NULL, not
NULL_RTX.
Neither of these nits require a new version for review. Just fix them.
If Juzhe is fine with this, so am I. We can refine it if necessary later.
