示例1: createVarSc
AstVarScope* createVarSc(AstVarScope* oldvarscp, string name, int width/*0==fromoldvar*/) {
// Because we've already scoped it, we may need to add both the AstVar and the AstVarScope
if (!oldvarscp->scopep()) oldvarscp->v3fatalSrc("Var unscoped");
AstVar* varp;
AstNodeModule* addmodp = oldvarscp->scopep()->modp();
// We need a new AstVar, but only one for all scopes, to match the new AstVarScope
VarMap::iterator iter = m_modVarMap.find(make_pair(addmodp,name));
if (iter != m_modVarMap.end()) {
// Created module's AstVar earlier under some other scope
varp = iter->second;
} else {
if (width==0) {
varp = new AstVar (oldvarscp->fileline(), AstVarType::BLOCKTEMP, name, oldvarscp->varp());
varp->widthSignedFrom(oldvarscp);
} else { // Used for vset and dimensions, so can zero init
varp = new AstVar (oldvarscp->fileline(), AstVarType::BLOCKTEMP, name, AstBitPacked(), width);
}
addmodp->addStmtp(varp);
