Ok, I *might* be getting this from the assembly code. The assembly code has: L_llvm_gc_root_chain$non_lazy_ptr: .indirect_symbol _llvm_gc_root_chain .long 0 and I see it being used in the function preamble. Is that a ref to an extern symbol or the def? I.e., is it referring to StackEntry *llvm_gc_root_chain; that I must have in my GC C code? (semispace.c has it) SO!

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 '*'
