[llvm-dev] Error cloning function from another module and setting it alwaysinline on custom pass (original) (raw)

Hi,

I wan't to clone function from another bitcode module and set it AlwaysInline so it can be inlined. But error occurs when applying a such custom pass. (It seems cause is usage of CloneFunction()) How can I fix it? I'm using LLVM 3.6.0 on OS X and target is Android armeabi-v7a. (It should be same on other target) I'll appreciate any advice. Thanks.
