[Question][HW3] coverage of instruction without metadata

[AnHaechan]

Should we instrument the __coverage__ function call
for the instruction without any !dbg metadata?

For example, LOC 23 of example3.ll is

if.else:                                         
%div1 = sdiv i32 40, %a, !dbg !21
call void @llvm.dbg.value(metadata i32 %div1, metadata !14, metadata !DIExpression()), !dbg !12  
br label %if.end ; LOC23

It does not matter for the pass/fail of test3 because the control flow never reaches to that instruction,
but I've got curious about general cases.

Should we consider making some hacky way to this case(where instruction does not have !debug metadata?)

No. Only consider instructions that have debug information.
