Bug 233596 – OSR exit loop for InBounds HasIndexedProperty that exits because of holes

• Status: NEW

[Saam Barati]

Something like this is an exit loop in "func":

function test1() {
    function func(o) {
        return 0 in o;
    }
    noInline(func);

    let o = {__proto__:[0, 1]};
    o[2] = 4;

    for (let i = 0; i < 10000; ++i) {
        func(o);
    }
    assert(func(true, o));
}
test1();
