示例1: Address
// Generate a stub that is called immediately after the prologue when there is a
// stack overflow. This stub calls a C++ function to report the error and then
// jumps to the throw stub to pop the activation.
static bool
GenerateStackOverflowStub(ModuleGenerator& mg, Label* throwLabel)
{
MacroAssembler& masm = mg.masm();
masm.haltingAlign(CodeAlignment);
Offsets offsets;
offsets.begin = masm.currentOffset();
masm.bind(masm.asmStackOverflowLabel());
// If we reach here via the non-profiling prologue, WasmActivation::fp has
// not been updated. To enable stack unwinding from C++, store to it now. If
// we reached here via the profiling prologue, we'll just store the same
// value again. Do not update AsmJSFrame::callerFP as it is not necessary in
// the non-profiling case (there is no return path from this point) and, in
// the profiling case, it is already correct.
Register activation = ABIArgGenerator::NonArgReturnReg0;
masm.loadWasmActivation(activation);
masm.storePtr(masm.getStackPointer(), Address(activation, WasmActivation::offsetOfFP()));
// Prepare the stack for calling C++.
if (uint32_t d = StackDecrementForCall(ABIStackAlignment, sizeof(AsmJSFrame), ShadowStackSpace))
masm.subFromStackPtr(Imm32(d));
// No need to restore the stack; the throw stub pops everything.
masm.assertStackAlignment(ABIStackAlignment);
masm.call(SymbolicAddress::ReportOverRecursed);
masm.jump(throwLabel);
if (masm.oom())
return false;
offsets.end = masm.currentOffset();
return mg.defineInlineStub(offsets);
}示例2:
// Generate a stub that is jumped to from an out-of-bounds heap access when
// there are throwing semantics. This stub calls a C++ function to report an
// error and then jumps to the throw stub to pop the activation.
static bool
GenerateConversionErrorStub(ModuleGenerator& mg, Label* throwLabel)
{
MacroAssembler& masm = mg.masm();
masm.haltingAlign(CodeAlignment);
Offsets offsets;
offsets.begin = masm.currentOffset();
masm.bind(masm.asmOnConversionErrorLabel());
// sp can be anything at this point, so ensure it is aligned when calling
// into C++. We unconditionally jump to throw so don't worry about restoring sp.
masm.andToStackPtr(Imm32(~(ABIStackAlignment - 1)));
// OnImpreciseConversion always throws.
masm.assertStackAlignment(ABIStackAlignment);
masm.call(SymbolicAddress::OnImpreciseConversion);
masm.jump(throwLabel);
if (masm.oom())
return false;
offsets.end = masm.currentOffset();
return mg.defineInlineStub(offsets);
