From f90a7e96df87edadd503a0a32aa70fb97c55a044 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 6 Apr 2020 06:02:11 -0700 Subject: i386: Disable check_consistency for GCC 5 and above [BZ #25788] check_consistency should be disabled for GCC 5 and above since there is no fixed PIC register in GCC 5 and above. Check __GNUC_PREREQ (5,0) instead OPTIMIZE_FOR_GCC_5 since OPTIMIZE_FOR_GCC_5 is false with -fno-omit-frame-pointer. --- sysdeps/unix/sysv/linux/i386/sysdep.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/unix/sysv/linux/i386/sysdep.h b/sysdeps/unix/sysv/linux/i386/sysdep.h index 5e3888060b..6671afe65e 100644 --- a/sysdeps/unix/sysv/linux/i386/sysdep.h +++ b/sysdeps/unix/sysv/linux/i386/sysdep.h @@ -580,8 +580,9 @@ struct libc_do_syscall_args # define EXTRAVAR_5 #endif -/* Consistency check for position-independent code. */ -#if defined __PIC__ && !defined OPTIMIZE_FOR_GCC_5 +/* Consistency check for position-independent code.
