All rights to this work released under the Creative Commons Zero Waiver. Abstract As domain-specific languages multiply, more tool support is needed to support compiler production. One major obstacle is debugging incorrect compiler translations. We built an interface prototype for a debugger that intersperses high-level source code with the low-level target code emitted by the compiler. The two versions can be stepped through in tandem and data in both versions can be examined, allowing inconsistencies to be pinpointed. Preliminary evaluations with compilers written using the SEJITS framework show users prefer the new debugger interface, use the add watch feature more, and exhibit unique debugging behaviors when using the tool.
