> I forgot this, but as demonstrated by your test, a typical symbol type output for a symbol in LLVM output style is "Section (0x3)". I don't think we want to repeat the number, and I therefore think simply printing "Unknown"/"OS Specific" etc in the first column is sufficient - the rest of the code then will append the "(0x7)" or whatever. In other words, the entries should be 3 "Unknown" strings, 2 "OS Specific" and 3 "Proc Specific".
