Examples with CompareAndSwapOp org.graalvm.compiler.lir.amd64.AMD64Move.CompareAndSwapOp used on opensource projects

Example 1 with CompareAndSwapOp

use of org.graalvm.compiler.lir.amd64.AMD64Move.CompareAndSwapOp in project graal by oracle.

the class AMD64LIRGenerator method emitLogicCompareAndSwap.

@Override
public Variable emitLogicCompareAndSwap(Value address, Value expectedValue, Value newValue, Value trueValue, Value falseValue) {
    ValueKind<?> kind = newValue.getValueKind();
    assert kind.equals(expectedValue.getValueKind());
    AMD64Kind memKind = (AMD64Kind) kind.getPlatformKind();
    AMD64AddressValue addressValue = asAddressValue(address);
    RegisterValue raxRes = AMD64.rax.asValue(kind);
    emitMove(raxRes, expectedValue);
    append(new CompareAndSwapOp(memKind, raxRes, addressValue, raxRes, asAllocatable(newValue)));
    assert trueValue.getValueKind().equals(falseValue.getValueKind());
    Variable result = newVariable(trueValue.getValueKind());
    append(new CondMoveOp(result, Condition.EQ, asAllocatable(trueValue), falseValue));
    return result;
}

Example 2 with CompareAndSwapOp
