From c23805a95d9bc095118299b5965f7f8388e57fc4 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 7 Jun 2016 22:54:58 +0000 Subject: Fix i386 asinhl (sNaN) (bug 20218). The i386 version of asinhl returns sNaN (without raising any exceptions) for sNaN input. This patch fixes it to add non-finite arguments to themselves, so that "invalid" is raised and qNaN returned. Tested for x86_64 and x86. [BZ #20218] * sysdeps/i386/fpu/s_asinhl.S (__asinhl): Add non-finite argument to itself. * math/libm-test.inc (asinh_test_data): Add sNaN tests. --- sysdeps/i386/fpu/s_asinhl.S | 1 + 1 file changed, 1 insertion(+) (limited to 'sysdeps') diff --git a/sysdeps/i386/fpu/s_asinhl.S b/sysdeps/i386/fpu/s_asinhl.S index c9d5714bee..e055386071 100644 --- a/sysdeps/i386/fpu/s_asinhl.S +++ b/sysdeps/i386/fpu/s_asinhl.S @@ -88,6 +88,7 @@ ENTRY(__asinhl) 4: ret 7: fldt 4(%esp) + fadd %st ret 6: faddl MO(one) -- cgit v1.2.3
