Example 1 with RegisterConfig

use of jdk.vm.ci.code.RegisterConfig in project graal by oracle.

the class AMD64HotSpotLeaveCurrentStackFrameOp method emitCode.

@Override
public void emitCode(CompilationResultBuilder crb, AMD64MacroAssembler masm) {
    FrameMap frameMap = crb.frameMap;
    RegisterConfig registerConfig = frameMap.getRegisterConfig();
    RegisterSaveLayout registerSaveLayout = saveRegisterOp.getMap(frameMap);
    Register stackPointer = registerConfig.getFrameRegister();
    // Restore integer result register.
    final int stackSlotSize = frameMap.getTarget().wordSize;
    Register integerResultRegister = registerConfig.getReturnRegister(JavaKind.Long);
    masm.movptr(integerResultRegister, new AMD64Address(stackPointer, registerSaveLayout.registerToSlot(integerResultRegister) * stackSlotSize));
    masm.movptr(rdx, new AMD64Address(stackPointer, registerSaveLayout.registerToSlot(rdx) * stackSlotSize));
    // Restore float result register.
    Register floatResultRegister = registerConfig.getReturnRegister(JavaKind.Double);
    masm.movdbl(floatResultRegister, new AMD64Address(stackPointer, registerSaveLayout.registerToSlot(floatResultRegister) * stackSlotSize));
    /*
         * All of the register save area will be popped of the stack. Only the return address
         * remains.
         */
    leaveFrameAndRestoreRbp(crb, masm);
    // Remove return address.
    masm.addq(stackPointer, crb.target.arch.getReturnAddressSize());
