[PATCH v10 08/61] target/riscv: add fault-only-first unit stride load

2020-06-19 Thread LIU Zhiwei
The unit-stride fault-only-fault load instructions are used to vectorize loops with data-dependent exit conditions(while loops). These instructions execute as a regular load except that they will only take a trap on element 0. Signed-off-by: LIU Zhiwei Reviewed-by: Alistair Francis Reviewed-by:
