From fe27057d1765c1cc42023bff4fdd71ce190fe35d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Mon, 30 Sep 2002 10:26:59 +0000 Subject: * elf/tls-macros.h (TLS_LD, TLS_GD): Use call insn, not callq. * sysdeps/unix/x86_64/sysdep.S [USE_TLS && HAVE___THREAD] [! PIC]: Use direct-%fs form of TLS access for errno. * sysdeps/unix/sysv/linux/i386/i686/sysdep.h: File removed, since the i386 version has all the same asm now. * sysdeps/i386/elf/configure.in: Add @GOTNTPOFF and @NTPOFF uses to the TLS support check. * sysdeps/i386/elf/configure: Regenerated. * sysdeps/unix/sysv/linux/i386/sysdep.h [USE_TLS && HAVE___THREAD] (SYSCALL_ERROR_HANDLER): Use direct-%gs form of TLS access for errno. * sysdeps/unix/i386/sysdep.S (syscall_error) [USE_TLS && HAVE___THREAD]: Use TLS access for errno. --- sysdeps/i386/elf/configure | 5 ++++- sysdeps/i386/elf/configure.in | 3 +++ 2 files changed, 7 insertions(+), 1 deletion(-) (limited to 'sysdeps/i386') diff --git a/sysdeps/i386/elf/configure b/sysdeps/i386/elf/configure index b9e5d7e79e..03f16fc798 100755 --- a/sysdeps/i386/elf/configure +++ b/sysdeps/i386/elf/configure @@ -20,8 +20,11 @@ baz: leal bar@TLSLDM(%ebx), %eax leal bar@DTPOFF(%eax), %edx subl foo@GOTTPOFF(%edx), %eax subl $bar@TPOFF, %eax + movl foo@GOTNTPOFF(%edx), %ecx + movl %gs:(%ecx), %eax + movl %gs:bar@NTPOFF, %eax EOF -if { ac_try='${CC-cc} -c $CFLAGS conftest.s 1>&5'; { (eval echo configure:25: \"$ac_try\") 1>&5; (eval $ac_try) 2>&5; }; }; then +if { ac_try='${CC-cc} -c $CFLAGS conftest.s 1>&5'; { (eval echo configure:28: \"$ac_try\") 1>&5; (eval $ac_try) 2>&5; }; }; then libc_cv_386_tls=yes else libc_cv_386_tls=no diff --git a/sysdeps/i386/elf/configure.in b/sysdeps/i386/elf/configure.in index 3c27d0171f..89a43b04b9 100644 --- a/sysdeps/i386/elf/configure.in +++ b/sysdeps/i386/elf/configure.in @@ -18,6 +18,9 @@ baz: leal bar@TLSLDM(%ebx), %eax leal bar@DTPOFF(%eax), %edx subl foo@GOTTPOFF(%edx), %eax subl $bar@TPOFF, %eax + movl foo@GOTNTPOFF(%edx), %ecx + movl %gs:(%ecx), %eax + movl %gs:bar@NTPOFF, %eax EOF dnl if AC_TRY_COMMAND(${CC-cc} -c $CFLAGS conftest.s 1>&AC_FD_CC); then -- cgit 1.4.1
