Power10 added "prefixed" instructions, which are effectively 64-bit instructions in two 32-bit halves (the nominal instruction size). They are primarily used for larger immediates and branch displacements.

- TanjB 3y agoMIPS had load const to high or low half. More that 40 years ago Transputer had shift-and-load 8 bit constants. Lots of ancient precedents for rare big constants.
