* [libcxxabi] Add "install-libcxxabi" target.Eric Fiselier2015-08-191-2/+10
| | | | | | | | | | | | | | Summary: Currently you can't install libc++abi from within the LLVM tree without installing all of LLVM. This patch adds an install rule for libc++abi.

| | | | | | | | | | | Currently, the tests assume the system compiler is the one we want to test, but if we build libcxxabi together with LLVM+Clang, it'll get the wrong compiler. This patch allows us to test if we have clang++ in our /bin directory, and if so, use it. llvm-svn: 243752

| | | | | | | | This papers over a layering violation currently between libc++abi and libunwind. It reaches into the sources to get the declaration of an ABI defined function. This should allow the ARM buildbot to continue building libc++abi again. llvm-svn: 235965

| | | | | | | | Attempting to default the option to ON for ARM doesnt seem to work. Force the check lower and perform the check at the two sites that matter: the CPPFLAGS definition and the header search path setup. llvm-svn: 235964

* libc++abi: silence some warningsSaleem Abdulrasool2015-04-271-1/+1
| | | | | | | | | Cleans up the -Wundef warning caused by the use of the __LITTLE_ENDIAN__ macro. Instead use `__BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__`. `__BYTE_ORDER__` is defined by GCC since 4.2 and by clang. This avoids the undef case where a macro may be undefined. This has previously caught real errors in libunwind. llvm-svn: 235828

| | | | | | | | | | | | | | | | | | | | | | | | | | | conversion detection. Summary: Currently there are bugs in out detection of multi-level pointer conversions and pointer to member conversions. This patch fixes the following issues. * Allow multi-level pointers with different nested qualifiers. * Allow multi-level mixed pointers to objects and pointers to members with different nested qualifiers. * Allow conversions from `int Base::*` to `int Derived::*` but only for non-nested pointers. There is still some work that needs to be done to clean this patch up but I want to get some input on it. Open questions: * Does `__pointer_to_member_type_info::can_catch(...)` need to adjust the pointer if a base to derived conversion is performed?

* Unwind: define more interfaces more oftenSaleem Abdulrasool2015-03-091-40/+36
| | | | | | | | | These are also part of the Unwind interfaces. However, their implementation is different in EHABI vs frame tables based exception handling. Always provide a definition. This partially undoes a movement change from earlier to make the handling a bit simpler rather than grouping the two implementations together. llvm-svn: 231690
* Unwind: always define unwind APIsSaleem Abdulrasool2015-03-091-4/+0
| | | | | | | | These interfaces are not zero cost related, but rather generic unwind APIs used by consumers of the Unwind library. Always provide the definition as they are needed for both Zero Cost and Frame Table based implementations. llvm-svn: 231666

* [libcxxabi] Build both static and shared versions of libc++abi by default.Eric Fiselier2015-03-033-25/+50
| | | | | | | | | | | | | | | | | | | | | | 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.

* Unwind: make it build on Darwin againSaleem Abdulrasool2015-02-281-2/+5

* Add .eh_frame_hdr search to Linux unwinder.Dan Albert2015-02-274-10/+242
| | | | | | | | | | | This improves the performance of unwinding on DWARF based targets. The 32-bit x86 support for scanning the full eh_frame (CFI_Parser::findFDE) apparently does not work (at least not on Linux). Since the eh_frame_hdr code delegates to that, this still doesn't work for x86 Linux, but it has been tested on x86_64 Linux and aarch64 Android. llvm-svn: 230802
