# TC-L Improvements¶

Possible improvements include:

Debug information

LLVM has support for debug information. If you want to generate debug information, have a look at Adding Debug Information.

LLVM generates DWARF code.

Start by emitting the locations of your nodes first, then go further with scopes and variables.

Global variables
As you noticed at TC-5, Translating to the High Level Intermediate Representation, you can’t have global variables. LLVM has support for global variables, using the GlobalVariable class.
