From de62046d68083a9a39ab29194adb6258a7ac76a9 Mon Sep 17 00:00:00 2001 From: Vlad Tsyrklevich Date: Tue, 19 Sep 2017 02:22:48 +0000 Subject: Allow public Triple deduction from ObjectFiles. Move logic that allows for Triple deduction from an ObjectFile object out of llvm-objdump.cpp into a public factory, found in the ObjectFile class. This should allow other tools in the future to use this logic without reimplementation.
