re PR middle-end/81088 (UBSAN: false positive as a result of reassosiation)
2017-06-14 Richard Biener <rguenther@suse.de>
PR middle-end/81088
* fold-const.c (split_tree): Drop TREE_OVERFLOW flag from
literal constants.
(fold_binary_loc): When associating do not treat pre-existing
TREE_OVERFLOW on literal constants as a reason to allow
TREE_OVERFLOW on associated literal constants.
* c-c++-common/ubsan/pr81088.c: New testcase.
