1431 because the inline candidate calls alloca or uses sjlj exceptions.
1432 (limits_allow_inlining): this new function to check if the inlining
1433 limits are satisfied. Throttle from currfn_max_inline_insns, not from
1434 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
1435 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.
1437 (tree_inlinable_function_p): Make a bool. Update call to
1438 inlinable_function_p
1439 (expand_call_inline): Use limits_allow_inlining() when not in
