// Regression test for https://bugs.webkit.org/show_bug.cgi?id=144152

// The bug in 144152 needs 3 conditions to manifest:
// 1. The branch test value in the inlined function is of useKind ObjectOrOtherUse.
// 2. The branch test value is proven to be a known useKind.
// 3. The masqueradesAsUndefined watchpoint is no longer valid.
// With the bug fixed, this test should not crash on debug builds.

function inlinedFunction(x) {
    if (x) // Conditional branch that will assert on a debug build if the bug is present.
        new Object;
}

function foo(x) {
    if (x) // Testing x before calling the inlined function sets up condition 2.
        inlinedFunction(x);
}

makeMasquerader(); // Invalidates the masqueradesAsUndefined watchpoint for condition 3.
for (var i = 0; i < 10000; i++)
    foo({}); // Pass an object argument to set up condition 1.
