From 388b4f1a02f3a801965028bbfcd48d905638b797 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 23 Jun 2017 14:38:46 -0700 Subject: Avoid .symver on common symbols [BZ #21666] The .symver directive on common symbol just creates a new common symbol, not an alias and the newer assembler with the bug fix for https://sourceware.org/bugzilla/show_bug.cgi?id=21661 will issue an error. Before the fix, we got $ readelf -sW libc.so | grep "loc[12s]" 5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1 5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2 5455: 00000000003a0618 8 OBJECT LOCAL DEFAULT 36 locs 6575: 00000000003a05f0 8 OBJECT GLOBAL DEFAULT 36 locs@GLIBC_2.2.5 7156: 00000000003a05f8 8 OBJECT GLOBAL DEFAULT 36 loc1@GLIBC_2.2.5 7312: 00000000003a0600 8 OBJECT GLOBAL DEFAULT 36 loc2@GLIBC_2.2.5 in libc.so.
