[PATCH 0/3] aarch64: ls64 builtin fixes [PR110100,PR110132]

[Alex Coplan]

Hi,

This patch series fixes various defects with the FEAT_LS64 ACLE
implementation in the AArch64 backend.

The series is organised as follows:

 - Patch 1/3 fixes whitespace errors in the existing code.
 - Patch 2/3 fixes PR110100 where we generate wrong code for the st64b
   builtin.
 - Patch 3/3 fixes PR110132, allowing the compiler to define the ACLE builtins
   directly, and also makes the builtins work under LTO.

Bootstrapped/regtested as a series on aarch64-linux-gnu. OK for trunk
and backports back to GCC 12?

Thanks,
Alex

Yeah, OK for trunk and branches.  Thanks for fixing this.
