Hi Jakub,
Thanks for the quick review.
Aside from code formatting issues, can I conclude that you suggest
we should rebase this onto your new big-endian support patch? Or
do you think it's necessary to add big-endian && extended support
together?

This series has been bootstrapped and regtested with x86_64-linux-gnu and
loongarch64-linux-gnu (against a version that leaves the partial limbs
undefined).
Please help us find if there's something we've missed.
Thanks,
Yujie
Yang Yujie (3):
The padding bits of _BitInt(N) are undefined in the x86-64 and
the aarch64 ABI. In general, the current lowering and expand process
perform truncations when taking a _BitInt value as input,
while leaving them as-is in the output.
By adding truncation on the output side, we can define psABIs

This patch adds support for C23's _BitInt for LoongArch.
Though there's not an official psABI definition, our plan
is to have 16-byte alignment for N > 64 and the padding bits

One exception would be "unsigned _BitInt(32)". To match the

Unfortunately, I was unable to reproduce the problem mentioned in
https://gcc.gnu.org/pipermail/gcc-patches/2023-October/631933.html
Heres's a possible fix without testing. Please tell me if this works.

Hi Zixing,
We are also working on a patch series that could pass the libphobos regression
tests.
Will post this later once all failed items are fixed.

Library build options from --with-multilib-list used to be processed with
*self_spec, which missed the driver's initial canonicalization. This
caused limitations on CFLAGS override and the use of driver-only options
like -m[no]-lsx.
The problem is solved by promoting the injection rules of --with
