From 955774751b71c4bc94029dd541ad9d34634ec995 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 3 Oct 2017 17:54:13 -0700 Subject: i386: Use "movl main@GOT(%ebx), %eax" in start.S Don't use "leal main@GOTOFF(%ebx), %eax" since main may be in a shared object. Linker will convert "movl main@GOT(%ebx), %eax" to "leal main@GOTOFF(%ebx), %eax" if main is defined locally. * sysdeps/i386/start.S: Replace "leal main@GOT(%ebx), %eax" with "movl main@GOTOFF(%ebx), %eax". --- ChangeLog | 5 +++++ sysdeps/i386/start.S | 7 +++++-- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index 01517c5514..a8d731c75d 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2017-10-03 H.J.
