From d49499c128f38e77f1b424ea4fabea0014dd95c1 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 23 Feb 2015 06:28:18 -0800 Subject: [PATCH] Compile gcrt1.o with -fPIC We compile gcrt1.o with -fPIC to support both "gcc -pg" and "gcc -pie -pg". [BZ #17836] * csu/Makefile (extra-objs): Add gmon-start.o if not builing shared library. Add gmon-start.os otherwise. ($(objpfx)g$(start-installed-name)): Use $(objpfx)S% $(objpfx)gmon-start.os if builing shared library. ($(objpfx)g$(static-start-installed-name)): Likewise. --- ChangeLog | 9 +++++++++ NEWS | 4 ++-- csu/Makefile | 13 +++++++++++-- 3 files changed, 22 insertions(+), 4 deletions(-) diff --git a/ChangeLog b/ChangeLog index 82299e5ebe..0a059097e4 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,12 @@ +2015-02-23 H.J.
