[PATCH v4 2/5] target/riscv: add vector stride load and store instructions |
|
Date: |
Tue, 25 Feb 2020 18:35:05 +0800 |
Vector strided operations access the first memory element at the base address,
and then access subsequent elements at address increments given by the byte
offset contained in the x register specified by rs2.
