[libcxx] [test] Add casts to avoid signed/unsigned mismatch warnings on MSVC++

2020-01-14T09:11:10+00:00

A bug was filed that these warnings should not be emitted as DevCom-883961. ( https://developercommunity.visualstudio.com/content/problem/883961/c4389-signedunsigned-mismatch-should-not-be-emitte.html )

[libc++] Fixed copy/copy_n/copy_backward for compilers that do not support is_constant_evaluated.

libcxx: Rename .hpp files in libcxx/test/support to .h

2019-08-21T00:14:12+00:00

LLVM uses .h as its extension for header files. Files renamed using: for f in libcxx/test/support/*.hpp; do git mv $f ${f%.hpp}.h; done References to the files updated using: for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do a=$(basename $f); echo $a; rg -l $a libcxx | xargs sed -i '' "s/$a/${a%.hpp}.h/"; done HPP include guards updated manually using: for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do echo ${f%.hpp}.h ; done | xargs mvim Differential Revision: https://reviews.llvm.org/D66104 llvm-svn: 369481

This patch makes swap functions constexpr. Both swap overloads, swap_ranges and iter_swap are updated (with tests).

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.

[libc++] Enable deprecation warnings by default

2019-03-12T20:10:06+00:00

Summary: In r342843, I added deprecation warnings to some facilities that were deprectated in C++14 and C++17. However, those deprecation warnings were not enabled by default. After discussing this on IRC, we had finally gotten consensus to enable those warnings by default, and I'm getting around to doing that only now.

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++.

D14686: 'Protect against overloaded comma in random_shuffle and improve tests' I had to cut back on the tests with this, because they were not C++03 friendly. Thanks to gribozavr for the patch
