[llvm-dev] How to use stack maps

[River Riddle via llvm-dev]

Hi,
  I implemented a garbage collector for a language I wrote in college using
the llvm gc statepoint infrastructure.

Information for statepoints:
https://llvm.org/docs/Statepoints.html

Example usage of parsing the llvm stackmap can be found at:
 https://github.com/dotnet/llilc/blob/master/lib/GcInfo/GcInfo.cpp
 https://llvm.org/docs/StackMaps.html#stackmap-format

https://github.com/llvm-mirror/llvm/blob/4604874612fa292ab4c49f96aedefdf8be1ff27e/include/llvm/Object/StackMapParser.h

Thanks,
 River Riddle
