From bdc969839aa55aec67860165087e1376a89edba2 Mon Sep 17 00:00:00 2001 From: Nico Weber Date: Tue, 6 May 2014 20:32:45 +0000 Subject: Include translation unit filename in global ctor symbol names. This makes it easier to see where a global ctor comes from, and it also makes ASan's init order analyzer output easier to understand. gcc does this too, but only in -fPIC mode for some reason. Don't do this for constructors with explicit init priority. Also prepend "sub_" before the 'I', that way regular constructors stay lexicographically after symbols with init priority (because ord('s') > ord('I')). gold seems to ignore the name of constructor symbols, and ld only looks at the symbol if it includes an init priority, which this patch doesn't change.
