I was thinking of just adding a pointer to an array of pointers to `@llvm.compiler.used`. The array itself would come from the bitcode library and would be populated there. I'm not sure if it's doable without knowing the array size, though. e.g ; Added by compiler @llvm.compiler.used = appending global [1 x i8*] [i8* bitcast ([16 x i8*]* @_ZL5funcs to i8*)], section "llvm.metadata" ; comes from the bitcode library, initialized with the pointers to functions you need to keep. @_ZL5funcs = internal global [16 x i8*] zeroinitializer, align 4 It should be possible to make the pointer to the array opaque with an intermadiate variable in the library.
