thread.general	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

thread.req	[libc++] Remove useless nothing_to_do.pass.cpp tests The testing script used to test libc++ historically did not like directories without any testing files, so these tests had been added. Since this is not necessary anymore, we can now remove these files. This has the benefit that the total number of tests reflects the real number of tests more closely, and we also skip some unnecessary work (especially relevant when running tests over SSH). However, some nothing_to_do.pass.cpp tests actually serve the purpose of documenting that an area of the Standard doesn't need to be tested, or is tested elsewhere. These files are not removed by this commit. Removal done with: import os import itertools for (dirpath, dirnames, filenames) in itertools.chain(os.walk('./libcxx/test'), os.walk('./libcxxabi/test')): if len(filenames + dirnames) > 1 and \ any(p == 'nothing_to_do.pass.cpp' for p in filenames): os.remove(os.path.join(dirpath, 'nothing_to_do.pass.cpp'))	6 年前
