Hi,Until a recent change, crtl->is_leaf was initialized only during IRA startup. On NVPTX, register allocation is not done, so the backend asserts that this field is unset, and recomputes it unconditionally. Now this field can be optionally set via ira_setup_eliminable_regset for register-pressure-sensitive optimizations, so the assumption in the backend no longer holds. Remove the assert, but avoid recomputing the field if it is already set, indicating that the function is known to be leaf. OK to apply? Thanks. Alexander PR target/78831 * config/nvptx/nvptx.c (init_softstack_frame): Remove assert. Compute crtl->is_leaf only if unset. Adjust comment.
OK. jeff
