Subject: [PATCH 2/2] [Clang][LoongArch] Fixed incorrect _BitInt(N>64)
alignment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch makes determining alignment and width of BitInt to be target
ABI specific and makes it consistent with [Procedure Call Standard for
the LoongArch™ Architecture] for LoongArch target
(https://github.com/loongson/la-abi-specs/blob/release/lapcs.adoc).
