This series of patches enhances the DTS source language to support a fullly interpreted language for generating nodes and properties. It is backward compatible with V1 sources.
The main features implemented by this patch set support function definitions, 'if', 'for', 'return' and assignment statements. Local variables, global constants and almost complete C-like expressions are also supported. Enhancements to the source position and error/warning reporting now support source column positions too. Version 1 was the original posting. Version 2 only fixed one patch in the series This is Version 3 and it includes fixes and suggestions due to community review and feedback, and includes a new patch that provides some testing. Git bisectability has been ensured as well. Jon Loeliger (9): Remove support for the legacy DTS source file format. Add conditionalized debug() print macro. Enhance source position implementation. Add header files for new Internal Representation form. Add most of the new IR implementation files. Add the main IR evaluation implementation Introduce new DTS language. Add documentation for the new DTS language. Test constant expressions in cell contexts.
