+ If you followed the steps outlined above, you already have
taught LLDB a great deal about your language. And if your language's runtime
model and fundamental data types don't differ much from the C model, you are
pretty much done.
+ <br/>
+ However, it is likely that your language offers its own data
types for things like strings, arrays, ..., and probably has a notion of
dynamic types, where the effective type of a variable can only be known at
runtime.
+ </p>
+ <p>
+ These tasks are covered by two plugins:
+ <ul>
+ <li>a LanguageRuntime plugin, which provides LLDB with a
dynamic view of your language; this plugin answers questions that require a
live process to acquire information (e.g. dynamic type resolution)</li>
+ <li>a Language plugin, which provides LLDB with a static view
of your language; questions that are statically knoawble and do not require a
process are answered by this plugin (e.g. data formatters)</li>
