[libc++][NFC] Move several .fail.cpp tests to .verify.cpp A few tests were also straightforward to translate to SFINAE tests instead, so in a few cases I did that and removed the .fail.cpp test entirely. Differential Revision: https://reviews.llvm.org/D153149 | 3 年前 | |
[libc++] Qualifies size_t. This has been done using the following command find libcxx/test -type f -exec perl -pi -e 's|^([^/]+?)((?<!::)size_t)|\1std::\2|' \{} \; And manually removed some false positives in std/depr/depr.c.headers. The std module doesn't export ::size_t, this is a preparation for that module. Reviewed By: ldionne, #libc, EricWF, philnik Differential Revision: https://reviews.llvm.org/D146088 | 3 年前 | |

Support tests in freestanding Summary: Freestanding is *weird*. The standard allows it to differ in a bunch of odd manners from regular C++, and the committee would like to improve that situation. I'd like to make libc++ behave better with what freestanding should be, so that it can be a tool we use in improving the standard. To do that we need to try stuff out, both with "freestanding the language mode" and "freestanding the library subset". Let's start with the super basic: run the libc++ tests in freestanding, using clang as the compiler, and see what works. The easiest hack to do this: In utils/libcxx/test/config.py add: self.cxx.compile_flags += ['-ffreestanding'] Run the tests and they all fail. Why? Because in freestanding main isn't special. This "not special" property has two effects: main doesn't get mangled, and main isn't allowed to omit its return statement. The first means main gets mangled and the linker can't create a valid executable for us to test. The second means we spew out warnings (ew) and the compiler doesn't insert the return we omitted, and main just falls of the end and does whatever undefined behavior (if you're luck, ud2 leading to non-zero return code). Let's start my work with the basics. This patch changes all libc++ tests to declare main as int main(int, char** so it mangles consistently (enabling us to declare another extern "C" main for freestanding which calls the mangled one), and adds return 0; to all places where it was missing. This touches 6124 files, and I apologize. The former was done with The Magic Of Sed. The later was done with a (not quite correct but decent) clang tool: https://gist.github.com/jfbastien/793819ff360baa845483dde81170feed This works for most tests, though I did have to adjust a few places when e.g. the test runs with -x c, macros are used for main (such as for the filesystem tests), etc. Once this is in we can create a freestanding bot which will prevent further regressions. After that, we can start the real work of supporting C++ freestanding fairly well in libc++. <rdar://problem/47754795> Reviewers: ldionne, mclow.lists, EricWF Subscribers: christof, jkorous, dexonsmith, arphaman, miyuki, libcxx-commits Differential Revision: https://reviews.llvm.org/D57624 llvm-svn: 353086 | 7 年前 | |

[libc++] Avoid including <tuple> in compressed_pair.h compressed_pair is widely used in the library, but most of the uses don't use the tuple parts.

[libc++] Use the stdlib=<LIB> Lit feature instead of use_system_cxx_lib The use_system_cxx_lib Lit feature was only used for back-deployment testing. However, one immense hole in that setup was that we didn't have a proper way to test Apple's own libc++ outside of back-deployment, which was embodied by the fact that we needed to define _LIBCPP_DISABLE_AVAILABILITY when testing (see change in libcxx/utils/libcxx/test/params.py). This led to the apple-system testing configuration not checking for availability markup, which is obviously quite bad since the library we ship actually has availability markup. Using stdlib=<VENDOR>-libc++ instead to encode back-deployment restrictions on tests is simpler and it makes it possible to naturally support tests such as availability markup checking even in the tip-of-trunk Apple-libc++ configuration.

[libc++] Move all the remaining .fail.cpp tests to .verify.cpp I made sure they all had some expected-error output in them.
