test/std/algorithms/alg.modifying.operations/alg.generate/generate_n.pass.cpp Silence MSVC warning C4244. This is expected when passing floating-point values for size. test/std/utilities/template.bitset/bitset.members/to_ullong.pass.cpp test/std/utilities/template.bitset/bitset.members/to_ulong.pass.cpp Avoid MSVC "warning C4293: '<<': shift count negative or too big, undefined behavior". MSVC sees (1ULL << N) and warns - being guarded by const bool canFit is insufficient. A small change to the code avoids the warning without the need for a pragma. Remove a spurious printf() declaration from to_ullong.pass.cpp. Change ULL to UL in to_ulong.pass.cpp. The ULL suffix was probably copy-pasted. test/std/utilities/tuple/tuple.general/ignore.pass.cpp Use LIBCPP_STATIC_ASSERT for consistency with other files. test/support/container_test_types.h Fix a null pointer dereference, found by MSVC /analyze warning C6011 "Dereferencing NULL pointer 'm_expected_args'." Fixes D41030. llvm-svn: 320535
