[v2,2/2] RISC-V: strcmp expansion: Use adjust_address() for address calculation
We have an arch-independent routine to generate an address with an offset.
Let's use that instead of doing the calculation in the backend.
gcc/ChangeLog:
* config/riscv/riscv-string.cc (emit_strcmp_scalar_load_and_compare):
Use adjust_address() to calculate MEM-PLUS pattern.
