Lioncash f5263cc196 thumb32: Implement exclusive loads 
Implements the remaining loads for ARMv7
 2021-04-19 19:46:19 +01:00
Lioncash 6241ff6be2 thumb32: Implement STREX variants 
Implements the exclusive store instructions. Now all that remains for
ARMv7 load/stores to be done is the exclusive loads.

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.
