How to link codon LLVM and functions of clang LLVM?

[iSunfield]

I've been trying to link C or C++ function assets at the LLVM level with codon code to see if LLVM optimizations can be applied to these C/C++ functions. However, I encounter errors when using llvm-link. Below is the small example that generates the error. How can I successfully link codon's LLVM code with LLVM functions codecompiled by Clang? Any advice would be greatly appreciated.

//--- C abs function(File name:LlvmAbsWrapper.c)
#include <math.h>

double abs_wrapper(double val) {
    return fabsf(val);
}

//--- Codon code(File name:LlvmAbs.codon)
@llvm
def abs_w(val: float) -> float:
    declare double @abs_wrapper(double)
    %0 = call double @abs_wrapper(double %val)
    ret double %0

A=-20
print(abs_w(A))

#-- Compile c code to LLVM
clang -S -emit-llvm LlvmAbsWrapper.c -o LlvmAbsWrapper.ll

#-- Compile code code to LLVM
codon build -llvm LlvmAbs.codon

#-- Link both LLVM 
llvm-link LlvmAbs.ll LlvmAbsWrapper.ll -o LlvmAbs.bc
