re PR sanitizer/81148 (UBSAN: two more false positives)
2017-08-03 Richard Biener <rguenther@suse.de>
PR middle-end/81148
* fold-const.c (split_tree): Add minus_var and minus_con
arguments, remove unused loc arg. Never generate NEGATE_EXPRs
here but always use minus_*.
(associate_trees): Assert we never associate with MINUS_EXPR
and NULL first operand. Do not recurse for PLUS_EXPR operands
when associating as MINUS_EXPR either.
(fold_binary_loc): Track minus_var and minus_con.
* c-c++-common/ubsan/pr81148.c: New testcase.
