Howdy do LLVM folks! I've exhausted what I can do on my own to make a GC example bind (usual googling, reading, playing, looking at source). I can't find the shadow collector lib or perhaps the -l options needed to link my sample (not even to point where I'm figuring out GC actually as I can't link). Not sure this IR is correct but here is what I've been playing

I just downloaded the source for release 2.2, and when I try to build 'make -C runtime' it fails with the following error: ---- [...] llvm[2]: Compiling semispace.c for Release build (bytecode) semispace.c:107: error: syntax error before 'ShadowStackEntry' semispace.c:107: warning: no semicolon at end of struct or union semispace.c:108: error: syntax error before '*' token semispace.c:108: warning: type defaults to 'int' in declaration of 'Map' semispace.c:108: warning: data definition has no type or storage class semispa...
