James, Thanks. It wouldn't take the LTO option; however, I can get it to inline using -cppgen=inline. However, when I run clang the second time it gives me an error, stating that it expects a top level entity. I think I've run into this issue before. Any ideas?

In Unladen Swallow we (intend to) compile each function as we determine it's hot. To "compile" a function means to translate it from CPython bytecode to LLVM IR, optimize the IR using a FunctionPassManager, and JIT the IR to machine code. We'd like to include inlining among our optimizations. Currently the Inliner is a CallGraphSCCPass, which can only be run by the

Hi Ryan, I see. Well, that shouldn't be an issue. If you link the bitcode files together with llvm-link you can then do several things: (1) Run clang on it as you normally would with -O3 for maximum inlining (2) Run 'llc' manually with -O3 and LTO, which will do the maximum link time optimisations. (3) Run 'opt' manually with -O3, LTO which will produce another bitcode file,

James, Sure. I want to inline functions in a C program that has no external node, or "main". So the "top" function is not main and there does not exist a main in the file. Thanks.
