3663 because the inline candidate calls alloca or uses sjlj exceptions.
3664 (limits_allow_inlining): this new function to check if the inlining
3665 limits are satisfied. Throttle from currfn_max_inline_insns, not from
3666 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
3667 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

3670 inlinable_function_p

3672 unit-at-a-time mode to decide on inlining. Don't use DID_INLINE_FUNC,
3673 instead see if the function was declared `inline'.
