James,<br><br> Thanks. It wouldn't take the LTO option; however, I can get it to inline using -cppgen=inline.<br><br> 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?<br>

Hi Ryan,<br>
<br>
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:<br>
<br>
(1) Run clang on it as you normally would with -O3 for maximum inlining<br>
(2) Run 'llc' manually with -O3 and LTO, which will do the maximum link time optimisations.<br>
(3) Run 'opt' manually with -O3, LTO which will produce another bitcode file, which you can then again give to Clang to codegen.<br>

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.<br>
<br>
Thanks.<br>

Sorry, I don't know to what you're referring here. Could you please rephrase? what do you mean be "external node"?<br>
<br>
Cheers,<br>

I believe it might actually. Do you know if it's possible to inline functions without an external node? It doesn't appear to be so.<br>

Hi Ryan,<br>
<br>
I would just compile to multiple IR files then link them together with llvm-link.<br>
<br>
Would that work for you?<br>
<br>

Clangers,<br>
<br>
What's the best way to compile multiple files in one LLVM IR file? It doesn't appear that clang supports the gcc -combine feature.<br>
