4902 because the inline candidate calls alloca or uses sjlj exceptions.
4903 (limits_allow_inlining): this new function to check if the inlining
4904 limits are satisfied. Throttle from currfn_max_inline_insns, not from
4905 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
4906 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

4909 inlinable_function_p
