Stack Map Artefact GC

This directory contains the implementation of the runtime system necessary to observe and test the LLVM generated stack maps.

GC API

Provides a few useful function calls which can be made from user-code.

Stack Map Parser

The Stack Map parser parses the .llvm_stackmaps section according to the LLVM V3 StackMap format. It begins parsing from the global __LLVM_StackMaps symbol. The parser then builds a map from this data which can queried by the stack walker at a later stage to identify the garbage collection rootset.
