From 980b4d536545de5f1aa9611c49f34af766d92a54 Mon Sep 17 00:00:00 2001 From: Mark Johnston Date: Sun, 16 Nov 2014 04:10:23 +0000 Subject: Remove an incorrect optimization. The type IDs of each member of a struct or union must be checked when determine whether two types are equivalent. This bug could cause ctfmerge(1) to incorrectly merge distinct types.
