471 limits_allow_inlining() function. Warn if inlining is impossible
472 because the inline candidate calls alloca or uses sjlj exceptions.
473 (limits_allow_inlining): this new function to check if the inlining
474 limits are satisfied. Throttle from currfn_max_inline_insns, not from
475 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
476 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.
478 (tree_inlinable_function_p): Make a bool. Update call to
480 (expand_call_inline): Use limits_allow_inlining() when not in
481 unit-at-a-time mode to decide on inlining. Don't use DID_INLINE_FUNC,
482 instead see if the function was declared `inline'.
