The original C++ file
Compiling with LLVM and clang r221928, I get a crash if the attached file is
stripped of debug info while being lazily loaded.
Using llvm-extract seems to be the only want to demonstrate a lazy module
loading test right now. If you patch llvm-extract with the attached patch,
then it will:
- Load the module lazily
- Strip the debug info
- Materialize the function.
Note that I'm calling it with
- clang++ lazy.cpp -o lazy.bc -emit-llvm -c -g
- llvm-extract -rfunc=".*foo" lazy.bc -o ext.bc
This is probably a bug in lazy materialization itself, or perhaps an
unsupported configuration.</pre>
