From b3ed821981e392d20d94028aeaa94b8ab31cc678 Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Tue, 20 Jul 1999 08:19:37 +0000 Subject: 1999-07-19 Andreas Schwab * libio/Makefile (routines): Add fwprintf. PowerPC has own version of w_sqrt.c and w_sqrtf.c. * math/w_sqrt.c: Moved to ... * sysdeps/generic/w_sqrt.c: ... here. * math/w_sqrtf.c: Moved to ... * sysdeps/generic/w_sqrtf.c: ... here. * Make-dist (generic-dirs): New variable. (try-sysdeps, +sysdep-names): Use it. * extra-lib.mk (all-$(lib)-routines): New variable. Use it instead of $(lib)-routines. * elf/Makefile (distribute): Add dl-cache.h. * db2/Makefile (distribute): Add all new files. * iconvdata/Makefile (distribute): Don't distribute CVS directory. * math/Makefile (distribute): Remove machine/endian.h, add math_ldbl.h. * stdio-common/Makefile (distribute): Add _itowa.h. * sysdeps/generic/Dist: Remove make_siglist.c, add siglist.h. * sysdeps/gnu/Dist: Add eval.c * sysdeps/gnu/Makefile (libdl-sysdep_routines) [$(subdir) = dlfcn]: Add to this instead of libdl-routines. * sysdeps/ieee754/ldbl-128/Dist: New file. * sysdeps/mach/hurd/Dist: Add siglist.h * sysdeps/unix/sysv/linux/Dist: Add kernel-features.h. --- sysdeps/generic/w_sqrt.c | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 sysdeps/generic/w_sqrt.c (limited to 'sysdeps/generic/w_sqrt.c') diff --git a/sysdeps/generic/w_sqrt.c b/sysdeps/generic/w_sqrt.c new file mode 100644 index 0000000000..be15d959ea --- /dev/null +++ b/sysdeps/generic/w_sqrt.c @@ -0,0 +1,47 @@ +/* @(#)w_sqrt.c 5.1 93/09/24 */ +/* + * ==================================================== + * Copyright (C) 1993 by Sun Microsystems, Inc.
