[LLVMdev] Function name changes in .bc on running llvm-g++

[Malveeka Tewari]

Hi

I am running llvm-g++ on a .cpp file to generate the llvm bitcode.

The function definition in the .cpp file is:

float pFL(Points *points, int *feasible, int numfeasible, float z, long *k,
      double cost, long iter, float e, int pid, pthread_barrier_t* barrier)
{

However, in the bit code I see that the function name has been modified to
the following

define float @_Z3pFLP6PointsPiifPldlfiP17pthread_barrier_t(%struct.Points*
%points, i32* %feasible, i32 %numfeasible, float %z, i32* %k, double %cost,
i32 %iter, float %e, i32 %pid, %union.pthread_barrier_t* %barrier) nounwind
{

What is the reason for the function renaming and is there a way to avoid so
that the function name remains unchanged.

This is how I am invoking llvm-g++
llvm-g++ -emit-llvm -c -O0 streamcluster.cpp -o streamcluster.bc

Thanks!
