示例1: emitCall
TCA emitCall(vixl::MacroAssembler& a, CppCall call) {
switch (call.kind()) {
case CppCall::Kind::Direct:
a. Mov (rHostCallReg, reinterpret_cast<intptr_t>(call.address()));
break;
case CppCall::Kind::Virtual:
a. Ldr (rHostCallReg, argReg(0)[0]);
a. Ldr (rHostCallReg, rHostCallReg[call.vtableOffset()]);
break;
case CppCall::Kind::IndirectReg:
case CppCall::Kind::IndirectVreg:
// call indirect currently not implemented. It'll be something like
// a.Br(x2a(call.getReg()))
not_implemented();
always_assert(0);
break;
case CppCall::Kind::ArrayVirt:
case CppCall::Kind::Destructor:
not_implemented();
always_assert(0);
break;
}
using namespace vixl;
auto fixupAddr = a.frontier();
a. HostCall(6);
// Note that the fixup address for a HostCall is directly *before* the
// HostCall, not after as in the native case. This is because, in simulation
// mode we look at the simulator's PC at the time the fixup is invoked, and it
// will still be pointing to the HostCall; it's not advanced past it until the
// host call returns. In the native case, by contrast, we'll be looking at
// return addresses, which point after the call.
