Subject: [AArch64] Add support for NEON scalar three register different instruction
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d867422c86914e055b8772ec1f22b349e15de94b;p=clang

[AArch64] Add support for NEON scalar three register different instruction
class.  The instruction class includes the signed saturating doubling
multiply-add long, signed saturating doubling multiply-subtract long, and
the signed saturating doubling multiply long instructions.
