2017-03-30[libc++abi] Delete config.hShoaib Meenai
Summary: It's now completely empty, so we can remove it entirely. Reviewers: mclow.lists, EricWF Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D31502 git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@299129 91177308-0d34-0410-b5e6-96231b3b80d8
2017-03-04Fully Reformat fallback_malloc.cppEric Fiselier
This patch fully reformats fallback_malloc.cpp. Previously the test was a mess of different styles and indentations. This made it very hard to work in and read. Therefore I felt it was best to re-format the whole thing. Unfortuantly this means some history will be lost, but hopefully much of it will still be accessible after ignoring whitespace changes. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@296960 91177308-0d34-0410-b5e6-96231b3b80d8
2017-03-04[libcxxabi] Fix alignment of allocated exceptions in 32 bit buildsEric Fiselier
Summary: In 32 bit builds on a 64 bit system `std::malloc` does not return correctly aligned memory. This leads to undefined behavior. This patch switches to using `posix_memalign` to allocate correctly aligned memory instead.

2017-03-01[libc++abi] Clean up visibilityShoaib Meenai
Use the libc++abi visibility macros instead of pragmas or using visibility attributes directly. Clean up redundant attributes on definitions (where the declarations already have visibility attributes applied, from either libc++ or libc++abi headers). Introduce _LIBCXXABI_WEAK as a drive-by cleanup, which matches the semantics of _LIBCPP_WEAK. No functional change. Tested by building on Linux before and after this change and verifying that the list of exported symbols is identical.

2017-01-03[libcxxabi] Introduce an externally threaded libc++abi variant.Asiri Rathnayake
r281179 Introduced an externally threaded variant of the libc++ library. This patch adds support for a similar library variant for libc++abi.

2016-10-13[libcxxabi] Refactor pthread usage into a separate APIAsiri Rathnayake
This patch refactors all pthread uses of libc++abi into a separate API. This is the first step towards supporting an externlly-threaded libc++abi library. I've followed the conventions already used in the libc++ library for the same purpose.

2016-10-07Recommit r282692: [libc++abi] Use fallback_malloc to allocate ↵Igor Kudrin
__cxa_eh_globals in case of dynamic memory exhaustion. Throwing an exception for the first time may lead to call calloc to allocate memory for __cxa_eh_globals. If the memory pool is exhausted at that moment, it results in abnormal termination of the program. This patch addresses the issue by using fallback_malloc in that case. In this revision, some restrictions were added into the test to not run it in unsuitable environments.
