We was assume the Z* extension should be more than 2 char, so we put an assertion there, but it should just an error or warning rather than an assertion, however RISC-V has add `Zk` extension, which just 2 char, so actually, we should just allow that. gcc/ChangeLog PR target/102957 * common/config/riscv/riscv-common.c (multi_letter_subset_rank): Remove assertion for Z*-ext. gcc/testsuite/ChangeLog * gcc.target/riscv/pr102957.c: New. (cherry picked from commit abe562bb01479ea2c8952ad98714f3225527aa7e)
