llvm-mirror/include/llvm/Support/AArch64TargetParser.def
Cullen Rhodes e25a1a8f41 [AArch64] Add target features for Armv9-A Scalable Matrix Extension (SME) 
First patch in a series adding MC layer support for the Arm Scalable
Matrix Extension.

This patch adds the following features:

    sme, sme-i64, sme-f64

The sme-i64 and sme-f64 flags are for the optional I16I64 and F64F64
features.

If a target supports I16I64 then the following instructions are
implemented:

  * 64-bit integer ADDHA and ADDVA variants (D105570).
  * SMOPA, SMOPS, SUMOPA, SUMOPS, UMOPA, UMOPS, USMOPA, and USMOPS
    instructions that accumulate 16-bit integer outer products into 64-bit
    integer tiles.

If a target supports F64F64 then the FMOPA and FMOPS instructions that
accumulate double-precision floating-point outer products into
double-precision tiles are implemented.

Outer products are implemented in D105571.
