2017-11-07Teach test suite about C++2a dialect flag.Eric Fiselier
This patch teaches the test suite configuration about the -std=c++2a flag. And, since it's the newest dialect, change the test suite to choose it, if possible, by default. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@317611 91177308-0d34-0410-b5e6-96231b3b80d8
2017-11-07Change test suite to support c++17 dialect flag instead of c++1z.Eric Fiselier
This patch changes the test suite to attempt and prefer -std=c++17 over -std=c++1z. It also fixes the REQUIRES and UNSUPPORTED lit markers to refer to c++17 over c++1z. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@317610 91177308-0d34-0410-b5e6-96231b3b80d8
2017-10-09[libc++] Support Microsoft ABI without vcruntime headersShoaib Meenai
The vcruntime headers are hairy and clash with both libc++ headers themselves and other libraries. libc++ normally deals with the clashes by deferring to the vcruntime headers and silencing its own definitions, but for clients which don't want to depend on vcruntime headers, it's desirable to support the opposite, i.e. have libc++ provide its own definitions. Certain operator new/delete replacement scenarios are not currently supported in this mode, which requires some tests to be marked XFAIL. The added documentation has more details.

2017-10-04[libc++] Add site config option for ABI macrosShoaib Meenai
Some ABI macros affect headers, so it's nice to have a site config option for them. Add a LIBCXX_ABI_DEFINES cmake macro to allow specifying a list of ABI macros to define in the site config. The primary design constraint (as discussed with Eric on IRC a while back) was to not have to repeat the ABI macro names in cmake, which only leaves a free-form cmake list as an option. A somewhat unfortunate consequence is that we can't verify that the ABI macros being defined actually exist, though we can at least perform some basic sanity checking, since all the ABI macros begin with _LIBCPP_ABI_.

2017-10-02Improve test runner output for broken configurations.Eric Fiselier
Previously LIT would often fail while attempting to set up/configure the test compiler; normally when attempting to dump the builtin macros. This sort of failure provided no useful information about what went wrong with the compiler, making the actual issues hard --- if not impossible --- to debug easily. This patch changes the LIT configuration to report the failure explicitly, including the failed compile command and the stdout/stderr output. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@314735 91177308-0d34-0410-b5e6-96231b3b80d8
2017-09-13Use CMAKE_AR instead of the system default 'ar' for merging static librariesMartin Storsjo
Using the system default 'ar' might not be the right choice when cross compiling. Don't prepend the ar options by a dash, not all ar implementations support that (llvm-ar doesn't). Also pass the 's' option when creating the merged library, to create an index.

2017-07-10Fix issues with UBSAN test configuration.Eric Fiselier
On Apple the test feature 'sanitizer-new-delete' was incorrectly getting added to the LIT feature set, which mistakenly caused tests to be disabled when using UBSAN (the feature is only needed with ASAN/MSAN/TSAN). git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@307518 91177308-0d34-0410-b5e6-96231b3b80d8
2017-07-08Fix filesystem build on platforms with weird time_t types.Eric Fiselier
32-bit powerpc provides a 64 bit time_t type and older ppc64 systems provide time_t as a floating point type. This caused problems when building operations.cpp since operations.cpp contained compile time tests for conversions between time_t and filesystem time type. When these tests failed they caused the libc++ build to fail as well. This is unfortunate. This patch moves the tests out of the source file and into the test suite. It also expands the tests to allow testing of the weird time_t configurations on all platforms. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@307461 91177308-0d34-0410-b5e6-96231b3b80d8

Libc++ is used as a system library on macOS and iOS (amongst others). In order for users to be able to compile a binary that is intended to be deployed to an older version of the platform, clang provides the availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_ that can be placed on declarations to describe the lifecycle of a symbol in the library.

2017-03-15Add deployment knobs to tests (for Apple platforms)Mehdi Amini
The tests for libc++ specify -target on the command-line to the compiler, but this is problematic for a few reasons. Firstly, the -target option isn't supported on Apple platforms. Parts of the triple get dropped and ignored. Instead, software should be compiled with a combination of the -arch and -m<name>-version-min options. Secondly, the generic "darwin" target references a kernel version instead of a platform version. Each platform has its own independent versions (with different versions of libc++.1.dylib), independent of the version of the Darwin kernel. This commit adds support to the LIT infrastructure for testing against Apple platforms using -arch and -platform options. If the host is not on OS X, or the compiler type is not clang or apple-clang, then this commit has NFC. If the host is on OS X and --param=target_triple=... is specified, then a warning is emitted to use arch and platform instead. Besides the warning, there's NFC. If the host is on OS X and *no* target-triple is specified, then use the new deployment target logic. This uses two new lit parameters, --param=arch=<arch> and --param=platform=<platform>. <platform> has the form <name>[<version>]. By default, arch is auto-detected from clang -dumpmachine, and platform is "macosx". If the platform doesn't have a version: For "macosx", the version is auto-detected from the host system using sw_vers. This may give a different version than the SDK, since new SDKs can be installed on older hosts. Otherwise, the version is auto-detected from the SDK version using xcrun --show-sdk-path. -arch <arch> -m<name>-version-min=<version> is added to the compiler flags. The target triple is computed as <arch>-apple-<platform>. It is *not* passed to clang, but it is available for XFAIL and UNSUPPORTED (as is with_system_cxx_lib=<target>). For convenience, apple-darwin and <arch>-apple-darwin are added to the set of available features. There were a number of tests marked to XFAIL on x86_64-apple-darwin11 and x86_64-apple-darwin12. I updated these to x86_64-apple-macosx10.7 and x86_64-apple-macosx10.8. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@297798 91177308-0d34-0410-b5e6-96231b3b80d8
