2016-03-17[libcxxabi] Disable cxa_thread_atexit_test if unavailableJonas Hahnfeld
The feature check is already in place when building the library but wasn't honored for the tests. Differential Revision: http://reviews.llvm.org/D18205 git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@263699 91177308-0d34-0410-b5e6-96231b3b80d8
2016-03-04Reducing stack usage of testBen Craig
This test has a lot of classes with large amounts of manually inserted padding in them, presumably to prevent various optimizations. The test then creates lots of these objects on the stack. On embedded targets, this was usually enough to overflow the stack. I moved the objects to global / namespace scope. Since the tests are each in their own namespace, there should be no cross-test conflicts. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@262717 91177308-0d34-0410-b5e6-96231b3b80d8
2016-01-20[libcxxabi] Make test tolerant of uncommon floating literal demanglingsBen Craig
libcxxabi uses the C99 library's %a format specifier to turn a floating point value into a hexadecimal string representation. The %a format specifier is rather loosely defined in the C spec though, and some C libraries emit a different (but valid) string for a given floating point value. In particular, the C spec only requires that there is a single, non-zero hexadecimal digit on the left of the decimal point. Given that constraint, there are typically four different valid representations of a floating point number. I have updated the test to accept any of the valid representations for demangled floating point literals. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@258311 91177308-0d34-0410-b5e6-96231b3b80d8

2015-03-03[libcxxabi] Build both static and shared versions of libc++abi by default.Eric Fiselier
Summary: This patch builds both static and shared versions of libc++abi by default. It adds/repurposes the following cmake options: * `LIBCXXABI_ENABLE_SHARED`: Enable/disable building the shared library. (Previously using `OFF` would build the static library instead) * `LIBCXXABI_ENABLE_STATIC`: Enable/disable building the static library. This patch also re-purposes the CMake target `cxxabi` to be a meta-target for `cxxabi_shared` and `cxxabi_static`. This could potentially break other builds that depend on `cxxabi` being a library target. We will need to apply a patch to libc++'s CMake before committing this change. Running the tests is still only supported when the shared version is built. Support for running the tests against the static library will come in another patch.

2014-12-29[cmake/multilib] Teach libc++abi's CMake build to support multilibChandler Carruth
libdir suffixes like 'lib64' or 'lib32'. This support is currently very rhudimentary. We define a variable LIBCXXABI_LIBDIR_SUFFIX. In a standalone build of libc++abi this can be directly set as a cached variable to control the multilib suffix used. When building libc++abi within a larger LLVM build, it is hard wired to whatever LLVM libdir suffix has been selected. If this doesn't work for someone, just let me know. I'm happy to change it. Unfortunately, libc++abi's lit setup made this somewhat problematic to change. It was setting variables up in a way that caused the resulting build to not work with lit at all. To fix that, I've moved some variables around in the CMake build to more closely match where and how they are defined in the libc++ CMake build. This includes specifically defining a library root variable in the CMake build where the libdir suffix can be applied, and then using that rather than re-computing it from the object directory in the lit config. This is essentially new functionality for libc++abi so I don't expect it to have any impact for folks until they start setting these variables. However, I know libc++abi is built in a diverse set of environments so just let me know if this causes you any problems. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@224927 91177308-0d34-0410-b5e6-96231b3b80d8
