re PR middle-end/37448 (cannot compile big function)
2016-02-22 Richard Biener <rguenther@suse.de>
PR ipa/37448
* ipa-inline-transform.c (inline_call): When not updating
overall summaries adjust self size by the growth estimate.
* ipa-inline.c (inline_to_all_callers_1): Add to the callers
hash-set, do not update overall summaries here. Renamed from ...
(inline_to_all_callers): ... this which is now wrapping the
above and performing delayed overall summary update.
(early_inline_small_functions): Delay updating of the overall
summary.
