Functions

build_expn_tree 🔒

Extracts raw span/BCB pairs from potentially-different syntax contexts, and arranges them into an “expansion tree” based on their expansion call-sites.

minmax_bcbs_for_expn_tree_node 🔒

For a single node in the expansion tree, compute its “minimum” and “maximum” BCBs (in dominator order), from among the BCBs of its immediate spans, and the min/max of its immediate children.

sort_nodes_depth_first 🔒

Sorts the tree nodes in the map into depth-first order.
