aarch64: fp8 convert and scale - add sme2 insn variants
Add the SME2 variant of the FP8 convert and scale
instructions, enabled at assembly-time using the `+sme2+fp8'
architectural extension flag. More specifically, support is
added for the following instructions:
Multi-vector floating-point convert from FP8 to
BFloat16 (in-order):
-----------------------------------------------
- bf1cvt { <Zd1>.H-<Zd2>.H }, <Zn>.B
- bf2cvt { <Zd1>.H-<Zd2>.H }, <Zn>.B
Multi-vector floating-point convert from FP8 to
deinterleaved BFloat16:
-----------------------------------------------
- bf1cvtl { <Zd1>.H-<Zd2>.H }, <Zn>.B
- bf2cvtl { <Zd1>.H-<Zd2>.H }, <Zn>.B
Multi-vector floating-point convert from BFloat16
to packed FP8 format:
-------------------------------------------------
- bfcvt <Zd>.B, { <Zn1>.H-<Zn2>.H }
Multi-vector floating-point convert from FP8 to
half-precision (in-order):
-----------------------------------------------
- f1cvt { <Zd1>.H-<Zd2>.H }, <Zn>.B
- f2cvt { <Zd1>.H-<Zd2>.H }, <Zn>.B
Multi-vector floating-point convert from FP8 to
deinterleaved half-precision:
-----------------------------------------------
- f1cvtl { <Zd1>.H-<Zd2>.H }, <Zn>.B
- f2cvtl { <Zd1>.H-<Zd2>.H }, <Zn>.B
Multi-vector floating-point convert from half-precision
to packed FP8 format:
-------------------------------------------------------
fcvt_2h
Multi-vector floating-point convert from single-precision
to packed FP8 format:
---------------------------------------------------------
fcvt_4s
Multi-vector floating-point convert from single-precision
to interleaved FP8 format:
---------------------------------------------------------
- fcvtn <Zd>.B, { <Zn1>.S-<Zn4>.S }
Multi-vector floating-point adjust exponent by vector:
------------------------------------------------------
- fscale { <Zdn1>.H-<Zdn2>.H }, { <Zdn1>.H-<Zdn2>.H },
<Zm>.H
- fscale { <Zdn1>.S-<Zdn2>.S }, { <Zdn1>.S-<Zdn2>.S },
<Zm>.S
- fscale { <Zdn1>.D-<Zdn2>.D }, { <Zdn1>.D-<Zdn2>.D },
<Zm>.D
Multi-vector floating-point adjust exponent:
--------------------------------------------
- fscale { <Zdn1>.H-<Zdn2>.H }, { <Zdn1>.H-<Zdn2>.H },
{ <Zm1>.H - <Zm2>.H }
- fscale { <Zdn1>.S-<Zdn2>.S }, { <Zdn1>.S-<Zdn2>.S },
{ <Zm1>.S - <Zm2>.S }
- fscale { <Zdn1>.D-<Zdn2>.D }, { <Zdn1>.D-<Zdn2>.D },
{ <Zm1>.D - <Zm2>.D }
