Comment #1 on issue 1476 by [email protected]: Incorrect code generated
for LModI with power-of-2 divisor
http://code.google.com/p/v8/issues/detail?id=1476
Thanks for the report!
This is a bug in code pattern generated for LModI with power-of-2 divisor
and no bailout on minus zero. Reduced testcase:
function foo (i) { return (i % 2) | 0; }
if (foo(-1) != -1) throw new Error("FAIL");
if (foo(-1) != -1) throw new Error("FAIL");
%OptimizeFunctionOnNextCall(foo);
if (foo(-1) != -1) throw new Error("FAIL");
