[llvm-dev] Why getNumOperands() incorrectly returns 0?

[Alberto Barbaro via llvm-dev]

Hi all,
I have encountered a weird case that I cannot understand. Inside the
visitStoreInst I have a reference (F) to the function png_set_mem_fn. If I
do F->dump() i can set the IR of that function correctly e.g.:

; Function Attrs: nounwind uwtable
define void @png_set_mem_fn(%struct.png_struct_def.68* noalias %png_ptr,
i8* %mem_ptr, i8* (%struct.png_struct_def.68*, i64)* %malloc_fn, void
(%struct.png_struct_def.68*, i8*)* %free_fn) #5 {
  ...
}
The problem is that when I do F->getNumOperands() I have 0 as result.

Can you explain me why please?

Thanks
