9576 because the inline candidate calls alloca or uses sjlj exceptions.
9577 (limits_allow_inlining): this new function to check if the inlining
9578 limits are satisfied. Throttle from currfn_max_inline_insns, not from
9579 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

9583 inlinable_function_p
