Author: dim Date: Mon Nov 11 17:41:56 2019 New Revision: 354625 URL: https://svnweb.freebsd.org/changeset/base/354625 Log: Merge commit 371ea70bb from llvm git (by Louis Dionne): [libc++] Harden usage of static_assert against C++03 In C++03, we emulate static_assert with a macro, and we must parenthesize multiple arguments. llvm-svn: 373328 This is a follow-up to r354460, which causes errors for pre-C++11 programs using <cmath>, similar to: /usr/include/c++/v1/cmath:622:68: error: too many arguments provided to function-like macro invocation Reported by: antoine MFC after: immediately (because of ports breakage) Modified: head/contrib/libc++/include/cmath Modified: head/contrib/libc++/include/cmath ============================================================================== --- head/contrib/libc++/include/cmath Mon Nov 11 17:41:52 2019 (r354624) +++ head/contrib/libc++/include/cmath Mon Nov 11 17:41:56 2019 (r354625) @@ -644,8 +644,8 @@ _LIBCPP_CONSTEXPR _IntT __max_representable_int_for_fl static_assert(is_floating_point<_FloatT>::value, "must be a floating point type"); static_assert(is_integral<_IntT>::value, "must be an integral type"); static_assert(numeric_limits<_FloatT>::radix == 2, "FloatT has incorrect radix"); - static_assert(_IsSame<_FloatT, float>::value || _IsSame<_FloatT, double>::value - || _IsSame<_FloatT,long double>::value, "unsupported floating point type"); + static_assert((_IsSame<_FloatT, float>::value || _IsSame<_FloatT, double>::value + || _IsSame<_FloatT,long double>::value), "unsupported floating point type"); return _FloatBigger ? numeric_limits<_IntT>::max() : (numeric_limits<_IntT>::max() >> _Bits << _Bits); }
