Help with bitcast instruction
Hi Tim, I'm still struggling on the instruction: call void bitcast (void (%struct.png_struct_def.68*, i8*, i8* (%struct.png_struct_def.68*, i64)*, void (%struct.png_struct_def.68*, i8*)*)* @png_set_mem_fn to void (%struct.png_struct_def*, i8*, i8* (%struct.png_struct_def*, i64)*, void (%struct.png_struct_def*, i8*)*)*)(%struct.png_struct_def* %create_struct, i8* %mem_ptr, i8* (%struct.png_struct_def*, i64)* %malloc_fn, void (%struct.png_struct_def*, i8*)* %free_fn) #15 I'm pretty sure that this...

Why getNumOperands() incorrectly returns 0?
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...
