From 40b8158b60e8b19dd5e2ed6bb796421ce49ff53a Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Fri, 26 Sep 2008 14:50:16 +0000 Subject: - move libm_hidden_proto to the corresponding headers. Remove from callsites. Note that gamma_r is not provided by glibc, perhaps add a SUN specific knob later --- libm/s_finitef.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 libm/s_finitef.c (limited to 'libm/s_finitef.c') diff --git a/libm/s_finitef.c b/libm/s_finitef.c new file mode 100644 index 000000000..66eba8f98 --- /dev/null +++ b/libm/s_finitef.c @@ -0,0 +1,32 @@ +/* s_finitef.c -- float version of s_finite.c. + * Conversion to float by Ian Lance Taylor, Cygnus Support, ian@cygnus.com. + */ + +/* + * ==================================================== + * Copyright (C) 1993 by Sun Microsystems, Inc.
