示例1: valueNode

// valueNode returns the id of the value node for v, creating it (and
// the association) as needed.  It may return zero for uninteresting
// values containing no pointers.
//
func (a *analysis) valueNode(v ssa.Value) nodeid {
	// Value nodes for locals are created en masse by genFunc.
	if id, ok := a.localval[v]; ok {
		return id
	}

	// Value nodes for globals are created on demand.
	id, ok := a.globalval[v]
	if !ok {
		var comment string
		if a.log != nil {
			comment = v.String()
		}
		id = a.addOneNode(v.Type(), comment, nil)
		if obj := a.objectNode(nil, v); obj != 0 {
			a.addressOf(id, obj)
		}
		a.setValueNode(v, id, nil)
	}
	return id
}

示例2: value

func (fr *frame) value(v ssa.Value) (result *LLVMValue) {
	switch v := v.(type) {
	case nil:
		return nil
	case *ssa.Function:
		result, ok := fr.funcvals[v]
		if ok {
			return result
		}
		// fr.globals[v] has the function in raw pointer form;
		// we must convert it to <f,ctx> form. If the function
		// does not have a receiver, then create a wrapper
		// function that has an additional "context" parameter.
		f := fr.resolveFunction(v)
		if v.Signature.Recv() == nil && len(v.FreeVars) == 0 {
			f = contextFunction(fr.compiler, f)
		}
		pair := llvm.ConstNull(fr.llvmtypes.ToLLVM(f.Type()))
		fnptr := llvm.ConstBitCast(f.LLVMValue(), pair.Type().StructElementTypes()[0])
		pair = llvm.ConstInsertValue(pair, fnptr, []uint32{0})
		result = fr.NewValue(pair, f.Type())
		fr.funcvals[v] = result
		return result
	case *ssa.Const:
		return fr.NewConstValue(v.Value, v.Type())
	case *ssa.Global:
		if g, ok := fr.globals[v]; ok {
			return g
		}
		// Create an external global. Globals for this package are defined
		// on entry to translatePackage, and have initialisers.
		llelemtyp := fr.llvmtypes.ToLLVM(deref(v.Type()))
		llglobal := llvm.AddGlobal(fr.module.Module, llelemtyp, v.String())
		global := fr.NewValue(llglobal, v.Type())
		fr.globals[v] = global
		return global
	}
	if value, ok := fr.env[v]; ok {
		return value
	}

	// Instructions are not necessarily visited before they are used (e.g. Phi
	// edges) so we must "backpatch": create a value with the resultant type,
	// and then replace it when we visit the instruction.
	if b, ok := fr.backpatch[v]; ok {
		return b
	}
	if fr.backpatch == nil {
		fr.backpatch = make(map[ssa.Value]*LLVMValue)
	}
	// Note: we must not create a constant here (e.g. Undef/ConstNull), as
	// it is not permissible to replace a constant with a non-constant.
	// We must create the value in its own standalone basic block, so we can
	// dispose of it after replacing.
	currBlock := fr.builder.GetInsertBlock()
	fr.builder.SetInsertPointAtEnd(llvm.AddBasicBlock(currBlock.Parent(), ""))
	placeholder := fr.compiler.builder.CreatePHI(fr.llvmtypes.ToLLVM(v.Type()), "")
	fr.builder.SetInsertPointAtEnd(currBlock)
	value := fr.NewValue(placeholder, v.Type())
	fr.backpatch[v] = value
	return value
}
