<boost/parameter/parameters.hpp>: * Add preprocessor conditional statement to prevent generation of ill-formed function call operator overloads. "test/maybe.cpp" "test/singular.cpp" "test/tutorial.cpp" "test/sfinae.cpp" "test/earwicker.cpp" * Replace BOOST_PARAMETER_KEYWORD statements with BOOST_PARAMETER_NAME statements. "test/optional_deduced_sfinae.cpp" "test/normalized_argument_types.cpp" "test/literate/*.cpp" * Use Boost.Core.LightweightTest where int main() is available. * Replace assert statements with BOOST_TEST_EQ statements. "test/basics.hpp" * Remove preprocessor statements regarding borland, gcc-2, and msvc workarounds. "test/ntp.cpp" "test/sfinae.cpp" "test/earwicker.cpp" "test/normalized_argument_types.cpp" "test/basics.hpp" * Add preprocessor conditional statement to #error out if BOOST_PARAMETER_MAX_ARITY is set to an insufficient value. "test/basics.cpp" "test/deduced.cpp" "test/macros.cpp" "test/preprocessor.cpp" "test/preprocessor_deduced.cpp" * Replace S and char const* expressions with boost::container::string expressions. * Uncomment any code that fails to compile, but add preprocessor conditional statement so that test suites can incorporate compile-fail statements regarding the code in question. * Ensure that int main() returns boost::process_errors(). "test/literate/deduced-template-parameters0.cpp": "test/literate/exercising-the-code-so-far0.cpp": * Enclose BOOST_MPL_ASSERT statements within MPL_TEST_CASE block. "test/literate/defining-the-keywords1.cpp": * Add graphs::tag::graph::qualifier type definition because perfect forwarding code will check for it. * Replace deprecated keyword::get() invocation with keyword::instance invocation. test/Jamfile.v2: * Add modifier <define>BOOST_PARAMETER_MAX_ARITY=# to run, run-fail, compile, and compile-fail statements to conserve compiler memory usage on GitHub's side. * Add modifier <preserve-target-tests>off to run and run-fail statements to conserve executable space on GitHub's side. * Separate bpl-test statement into its own target, parameter_python_test, which fails on xcode8.3 as well as on mingw and msvc compilers with address-model=64. * The next commit (which will implement perfect forwarding) will subsume test/literate/Jamfile.v2 into this file. Strangely enough, attempting to do so now will result in compiler errors. .travis.yml: * Add g++-4.7, g++-4.8, g++-4.9, clang++-3.5, clang++-3.6, clang++-3.7, clang++-3.8, clang++-3.9, clang++-4.0, xcode7.3, and xcode8.3 compiler configurations. * Split compiler configurations by available CXXSTD values. (This will keep the job times within limits for the next commit.) * Ensure that the xcode8.3 compiler configurations exclude parameter_python_test from the test suite. appveyor.yml: * Add compiler configurations that support address-model=64 to the test matrix. * Ensure that the new configurations exclude parameter_python_test from the test suite.
