6724 because the inline candidate calls alloca or uses sjlj exceptions.
6725 (limits_allow_inlining): this new function to check if the inlining
6726 limits are satisfied. Throttle from currfn_max_inline_insns, not from
6727 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

6731 inlinable_function_p
