RISC-V: List valid -mtune options only once
This patch ensures that the list of valid -mtune options
does not contain entries more than once.
The -mtune option accepts CPU identifiers as well as
tuning identifiers and there are cases where a CPU and
its tuning have the same identifier.
PR116347
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc
(riscv_get_valid_option_values):
Skip adding mtune entries that are already in the list.
