re PR bootstrap/49914 (call to abs(long long) in gcc/fold-const.c)
2011-08-02 Paolo Carlini <paolo.carlini@oracle.com>
PR bootstrap/49914
* fold-const.c (fold_plusminus_mult_expr): Use abs_hwi instead
of abs.
* tree-ssa-math-opts.c (gimple_expand_builtin_pow): Likewise.
* tree-ssa-loop-prefetch.c (prune_ref_by_group_reuse): Likewise.
