From 0a207fde24528c60297d015564b130a1a1c00a94 Mon Sep 17 00:00:00 2001 From: jakub Date: Mon, 28 Nov 2005 19:51:02 +0000 Subject: libfortran/24991 * acinclude.m4 (LIBGFOR_CHECK_PRAGMA_WEAK): Rename to... (LIBGFOR_GTHREAD_WEAK): ... this. Define SUPPORTS_WEAK rather than HAVE_PRAGMA_WEAK. Define GTHREAD_USE_WEAK to 0 on hosts that shouldn't use weak in gthr.h. * configure.ac: Use LIBGFOR_GTHREAD_WEAK instead of LIBGFOR_CHECK_PRAGMA_WEAK. * config.h.in: Regenerated. * configure: Regenerated. * io/io.h (SUPPORTS_WEAK): Don't define here. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@107616 138bc75d-0d04-0410-961f-82ee72b054a4 --- libgfortran/acinclude.m4 | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'libgfortran/acinclude.m4') diff --git a/libgfortran/acinclude.m4 b/libgfortran/acinclude.m4 index 9d06a8b84d4..3af0c0ea476 100644 --- a/libgfortran/acinclude.m4 +++ b/libgfortran/acinclude.m4 @@ -174,7 +174,7 @@ target_thread_file=`$CC -v 2>&1 | sed -n 's/^Thread model: //p'`]) fi]) dnl Check for pragma weak. -AC_DEFUN([LIBGFOR_CHECK_PRAGMA_WEAK], [ +AC_DEFUN([LIBGFOR_GTHREAD_WEAK], [ AC_CACHE_CHECK([whether pragma weak works], have_pragma_weak, [ gfor_save_CFLAGS="$CFLAGS" @@ -183,9 +183,15 @@ AC_DEFUN([LIBGFOR_CHECK_PRAGMA_WEAK], [ #pragma weak foo], [if (foo) foo ();], have_pragma_weak=yes, have_pragma_weak=no)]) if test $have_pragma_weak = yes; then - AC_DEFINE(HAVE_PRAGMA_WEAK, 1, + AC_DEFINE(SUPPORTS_WEAK, 1, [Define to 1 if the target supports #pragma weak]) - fi]) + fi + case "$host" in + *-*-darwin* | *-*-hpux* | *-*-cygwin*) + AC_DEFINE(GTHREAD_USE_WEAK, 0, + [Define to 0 if the target shouldn't use #pragma weak]) + ;; + esac]) dnl Check whether target can unlink a file still open.
