Treehydra

From MDC

Treehydra is a GCC plugin that provides a low level JavaScript binding to GCC's GIMPLE AST representation. Treehydra is intended for precise static analyses.

Most of Treehydra is generated by Dehydra. A Dehydra walks the GCC tree node structure using the GTY attributes present in GCC. Treehydra is included in Dehydra source, but isn't built by default.

For description of node types used in Treehydra see tree.def and cp-tree.def in the GCC sources.
