New Revision: 9afa5b8da2282ffaf21288d4bf2fdf19ea182dbb
URL: https://github.com/llvm/llvm-project/commit/9afa5b8da2282ffaf21288d4bf2fdf19ea182dbb

LOG: [RISCV] Add tests for (load (add X, [2048,4094])). NFC
Offsets in the range [-4095,-2049] or [2048, 4094] are split into
two ADDIs. One of the ADDIs will be folded into the load/store
immediate through an post-isel peephole.
