Detailed Description

A convenience builder class for complex constant initializers, especially for anonymous global structures used by various language runtimes.

The basic usage pattern is expected to be something like: ConstantInitBuilder builder(CGM); auto toplevel = builder.beginStruct(); toplevel.addInt(CGM.SizeTy, widgets.size()); auto widgetArray = builder.beginArray(); for (auto &widget : widgets) { auto widgetDesc = widgetArray.beginStruct(); widgetDesc.addInt(CGM.SizeTy, widget.getPower()); widgetDesc.add(CGM.GetAddrOfConstantStringFromLiteral(widget.getName())); widgetDesc.add(CGM.GetAddrOfGlobal(widget.getInitializerDecl())); widgetDesc.finishAndAddTo(widgetArray); } widgetArray.finishAndAddTo(toplevel); auto global = toplevel.finishAndCreateGlobal("WIDGET_LIST", Align, /*constant*‍/ true);
