From 01e094f82d8d91e08f62465a2e4f7a4c4897f9cd Mon Sep 17 00:00:00 2001 From: Alexandre Oliva Date: Mon, 27 Jun 2022 10:34:19 -0300 Subject: [PATCH] libstdc++: testsuite: use cmath long double overloads In case we need to supplement the C standard library with additional definitions for float and long double, the declarations expected to be in the C headers may not be there. Rely on the cmath overloads instead. for libstdc++-v3/ChangeLog * testsuite/20_util/to_chars/long_double.cc: Use cmath long double overloads for nexttoward and ldexp. --- libstdc++-v3/testsuite/20_util/to_chars/long_double.cc | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/libstdc++-v3/testsuite/20_util/to_chars/long_double.cc b/libstdc++-v3/testsuite/20_util/to_chars/long_double.cc index 0b1c2c2..4983881 100644 --- a/libstdc++-v3/testsuite/20_util/to_chars/long_double.cc +++ b/libstdc++-v3/testsuite/20_util/to_chars/long_double.cc @@ -54,11 +54,11 @@ namespace detail { long double nextupl(long double x) - { return nexttowardl(x, numeric_limits::infinity()); } + { return nexttoward(x, numeric_limits::infinity()); } long double nextdownl(long double x) - { return nexttowardl(x, -numeric_limits::infinity()); } + { return nexttoward(x, -numeric_limits::infinity()); } } // The long double overloads of std::to_chars currently just go through printf @@ -138,7 +138,7 @@ test01() for (int exponent : {-11000, -3000, -300, -50, -7, 0, 7, 50, 300, 3000, 11000}) for (long double testcase : hex_testcases) { - testcase = ldexpl(testcase, exponent); + testcase = ldexp(testcase, exponent); if (testcase == 0.0L || isinf(testcase)) continue; -- 2.7.4
