* Fast compiles and low memory use * Expressive diagnostics * GCC compatibility * A real-world, production quality compiler * A simple and hackable code base * A single unified parser for C, Objective C, C++, and Objective C++ * Conformance with C/C++/ObjC and their variants

* SRB Mode Debugging - As IBM creates more and more SRB-only System Interfaces, the ability to debug them interactively becomes more and more valuable. * Cross Memory Mode Debugging - z/XDC has extensive capabilities for debugging code with the Primary, Secondary and Home address spaces all being the same, or different in any conceivable way. * Simple Control Block Maps - z/XDC provides DSECT maps for thousands of IBM control blocks. Creating DSECT maps for your own control blocks is trivially easy. * Source Listing Support - z/XDC automatically loads source image maps (from ADATA), making your code in storage as easy to read as an assembly listing. * Comprehensive Mapping - z/XDC uses ADATA, SYM data and/or ESD data (whatever's available, whatever's necessary) for creating Linkedit/Binder maps, CSECT maps, and DSECT maps to help you visualize your code, data and control blocks.
