Expand description
Generates the FENCE.I
instruction
A FENCE.I instruction ensures that a subsequent instruction fetch on a RISC-V hart will see any previous data stores already visible to the same RISC-V hart.
FENCE.I does not ensure that other RISC-V harts’ instruction fetches will observe the local hart’s stores in a multiprocessor system.
