2017-03-30[libc++abi] Remove unistd.h includeShoaib Meenai
This was originally there for the _POSIX_THREADS define, to detect the presence of pthreads. That went away with the externalized threading support, so the include can go away too. config.h is now completely empty.

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

Summary: In 32 bit builds on a 64 bit system `std::malloc` does not return correctly aligned memory. This leads to undefined behavior.

2017-03-02[libc++abi] Add option to enable definitions for the new/delete overloads.Eric Fiselier
Summary: Currently both libc++ and libc++abi provide definitions for operator new/delete. However I believe this is incorrect and that one or the other should offer them. This patch adds the CMake option `-DLIBCXXABI_ENABLE_NEW_DELETE_DEFINITIONS` which defaults to `OFF` unless otherwise specified. This means that by default only libc++ provides the new/delete definitions.

Summary: Currently both libc++ and libc++abi provide definitions for new/delete. However libc++abi's definitions haven't been updated to include aligned new/delete or sized deallocation. I don't see any reason why libc++abi shouldn't provide these newer overloads. This patch copies libc++'s implementation of `new/delete` into libc++abi so that it's now up to date. After applying this patch I plan to fix a longstanding bug where both libc++ and libc++abi provide definitions for new/delete.

This patch cleans up how libc++abi handles the definitions for new/delete. It is in preperation for upcoming changes to fix how both libc++ and libc++abi handle new/delete. The primary changes in this patch are: * Move the definitions for bad_array_length and bad_new_array_length into stdlib_exception.cpp. This way stdlib_new_delete.cpp only contains new/delete. * Rename cxa_new_delete.cpp -> stdlib_new_delete.cpp for consistency with other files. * Add a FIXME regarding when stdlib_new_delete.cpp is actually compiled as part of the dylib. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@296715 91177308-0d34-0410-b5e6-96231b3b80d8

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.

2017-01-24cxa_demangle: fix rvalue ref checkSaleem Abdulrasool
When checking if the type is a r-value ref, we would not do a complete check. This would result in us treating a trailing parameter reference `&)` as a r-value ref, and improperly inject the cv qualifier on the type.

Ensure that we have a mangled symbol before attempting to demangle it. We would previously treat any input as a mangled symbol rather than checking that the symbol has the initial C++ Itanium v3 mangling prefix of `_Z`.
