powerpc/sstep: Let compute tests specify a required cpu feature (301ebf7d) · Commits · 戴 / test

An a array of struct compute_test's are used to declare tests for compute instructions. Add a cpu_feature field to struct compute_test as an optional way to specify a cpu feature that must be present. If not present then skip the test. Signed-off-by:
