a64: Add v8.7 instruction additions to the decoder
 2021-03-10 21:19:03 +00:00
Lioncash 035580abd2 a64: Add v8.7 instruction additions to the decoder 
Adds the instructions introduced in FEAT_WFxT and FEAT_LS64/FEAT_LS64_V
in ARMv8.7

Lioncash fb30922cd1 thumb32: Add supporting decoder entry for PLD (literal) 
LDRH (literal)'s pseduocode indicates that cases where Rt specifies the
PC, that the instruction should be execured as if it were a PLD
instruction.

Curiously, however, within the ARM reference manual, the encodings in the case
that happens doesn't match up.

The bit pattern for LDRH (literal) has bit 21 set to 1, but the encoding
of PLD (literal) has bit 21 set to zero for it's only thumb encoding.
