[llvm-dev] Inlining functions from multiple assembly files

In continuation to my previous doubt, I have an LLVM module with multiple
functions. I am adding the AlwaysInline attribute to all functions and
running createAlwaysInlinerLegacyPass. But 3-4 large functions are not
getting inlined. Is there any way to ensure all the functions in the module
are inlined irrespective of their size?
