From 09096b36152dca599ca781b7299d0d662ca74ce7 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 8 Jun 2016 22:59:18 +0000 Subject: Fix i386/x86_64 log10l (sNaN) (bug 20228). The i386/x86_64 versions of log10l return sNaN for sNaN input. This patch fixes them to add a NaN input to itself so that qNaN is returned in this case. Tested for x86_64 and x86. [BZ #20228] * sysdeps/i386/fpu/e_log10l.S (__ieee754_log10l): Add NaN input to itself. * sysdeps/x86_64/fpu/e_log10l.S (__ieee754_log10l): Likewise. * math/libm-test.inc (log10_test_data): Add sNaN tests. --- math/libm-test.inc | 2 ++ 1 file changed, 2 insertions(+) (limited to 'math') diff --git a/math/libm-test.inc b/math/libm-test.inc index c16009b9ae..e2a4ed38bc 100644 --- a/math/libm-test.inc +++ b/math/libm-test.inc @@ -9026,6 +9026,8 @@ static const struct test_f_f_data log10_test_data[] = TEST_f_f (log10, plus_infty, plus_infty, ERRNO_UNCHANGED), TEST_f_f (log10, qnan_value, qnan_value, NO_INEXACT_EXCEPTION|ERRNO_UNCHANGED), TEST_f_f (log10, -qnan_value, qnan_value, NO_INEXACT_EXCEPTION|ERRNO_UNCHANGED), + TEST_f_f (log10, snan_value, qnan_value, INVALID_EXCEPTION), + TEST_f_f (log10, -snan_value, qnan_value, INVALID_EXCEPTION), AUTO_TESTS_f_f (log10), }; -- cgit v1.2.3
