This patch adds printing for DW_AT_type DIEs like it is already the case for DW_AT_specification DIEs. This is a rather naive approach and only a start. We should have pretty printers for different languages. Recommit after being reverted in r315299. Differential revision: https://reviews.llvm.org/D36993 llvm-svn: 315316
