libcxx: Rename last two .hpp files in libcxx to .h

2019-08-21T22:38:38+00:00

Differential Revision: https://reviews.llvm.org/D66544 llvm-svn: 369597

Add include for 'test_macros.h' to all the tests that were missing them. Thanks to Zoe for the (big, but simple) patch. NFC intended.

Support tests in freestanding

2019-02-04T20:31:13+00:00

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++.

Update more file headers across all of the LLVM projects in the monorepo

2019-01-19T10:56:40+00:00

to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648

Un-XFAIL a test under new GCC version; the GCC bug has been fixed

2018-03-22T19:18:08+00:00

llvm-svn: 328229

Fix most GCC test failures.

2018-01-18T03:41:06+00:00

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

[libcxx] [test] Rename _Up to U, etc. NFCI.

2017-08-11T20:54:09+00:00

This improves readability and (theoretically) improves portability, as _Ugly names are reserved. This performs additional de-uglification, so all of these tests follow the example of iterator.traits/empty.pass.cpp. llvm-svn: 310761

[libcxx] [test] Rename _Tp to T. NFCI.
