From decf22e50fd4568e886c6a6a7eaabc0d4d1066d2 Mon Sep 17 00:00:00 2001 From: Eric Fiselier Date: Thu, 18 Jan 2018 03:41:06 +0000 Subject: Fix most GCC test failures. This patch fixes almost all currently failing tests when using GCC ToT. The specific changes are: (A) Workaround gcc.gnu.org/PR83921 which rejects variables w/o initializers in constexpr contexts -- even when the variable is an empty class. This bug has been worked around at all callsites by adding an initializer. Additionally a new test, constexpr_init.pass.cpp, has been added to test that Clang doesn't suffer from these bugs. (B) Fix streambuf.assign/swap.pass.cpp. This test was never actually calling the swap method as intended. In fact, the swap function it intended to call was ill-formed when instantiated. GCC diagnosed this ill-formedness w/o needing an instantiation. (C) size_delete11.pass.cpp was fixed by adding c++2a to the list of unsupported dialects. llvm-svn: 322810 --- .../alg.nonmodifying/alg.is_permutation/is_permutation_pred.pass.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libcxx/test/std/algorithms/alg.nonmodifying/alg.is_permutation') diff --git a/libcxx/test/std/algorithms/alg.nonmodifying/alg.is_permutation/is_permutation_pred.pass.cpp b/libcxx/test/std/algorithms/alg.nonmodifying/alg.is_permutation/is_permutation_pred.pass.cpp index 1d7db8cbc74..6c40ce368db 100644 --- a/libcxx/test/std/algorithms/alg.nonmodifying/alg.is_permutation/is_permutation_pred.pass.cpp +++ b/libcxx/test/std/algorithms/alg.nonmodifying/alg.is_permutation/is_permutation_pred.pass.cpp @@ -29,12 +29,12 @@ bool counting_equals ( const T &a, const T &b ) { } #if TEST_STD_VER > 17 -TEST_CONSTEXPR bool test_constexpr() { +constexpr bool test_constexpr() { int ia[] = {0, 0, 0}; int ib[] = {1, 1, 0}; int ic[] = {1, 0, 1}; int id[] = {1}; - std::equal_to c; + std::equal_to c{}; return !std::is_permutation(std::begin(ia), std::end(ia), std::begin(ib) , c) && !std::is_permutation(std::begin(ia), std::end(ia), std::begin(ib), std::end(ib), c) && std::is_permutation(std::begin(ib), std::end(ib), std::begin(ic) , c) -- cgit v1.2.3
