Summary: call to abs(long long) in gcc/fold-const.c
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Hello,
in gcc/fold-const.c (currently line 7051), in function
fold_plusminus_mult_expr:
if (exact_log2 (abs (int11)) > 0 && int01 % int11 == 0
where int11 is a HOST_WIDE_INT. Is this call to abs safe? A few lines above,
abs is computed as x>=0?x:-x.
(don't know how to classify this, but it causes a build failure for me with a
C++98 compiler (ambiguous))
