2014-03-20Fix DW_CFA_GNU_args_size handling. The primary architecture using thisJoerg Sonnenberger
opcode is VAX. A function call pushes the number of arguments given onto the stack and "ret" will pop it automatically. The FDE of the caller contains the amount of stack space used for arguments (and possibly extra padding), so unwinding has to compensate for this when "returning" from a function. This is exactly the case when step() is done. The existing handling in unw_set_reg no longer makes sense. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@204290 91177308-0d34-0410-b5e6-96231b3b80d8

2013-12-11Fix demangling crasher. The crasher involved nested <encoding> involving ↵Howard Hinnant
parameter packs, which exposed a logic bug causing an empty vector<string> to be accessed with back(). In addition to fixing the bug, I've inserted numerous preemptive checks for similar bugs in the hopes that if another bug is uncovered, the bug results in an invalid mangled string instead of a demangler crash.

2013-11-22On Windows, typeids are different between DLLs and EXEs, so comparingYaron Keren
type_info* will work for typeids from the same compiled file but fail for typeids from a DLL and an executable. Among other things, exceptions are not caught by handlers since can_catch() returns false. Defining _LIBCXX_DYNAMIC_FALLBACK does not help since can_catch() calls is_equal() with use_strcmp=false so the string names are not compared. This patch compares typeids first (cheap) and only they are different calls strcmp. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@195502 91177308-0d34-0410-b5e6-96231b3b80d8

2013-10-07libcxxabi contains the runtime support for C++. But, as some folks have Nick Kledzik
realized, it is not complete. It relies on some _Unwind_* functions to be supplied by the OS. That means it cannot be ported to platforms that don’t already have an unwinder. Years ago Apple wrote its own unwinder for MacOSX and iOS. To make libcxxabi complete, Apple has decided the source code for its unwinder can be contributed to the open source LLVM libcxxabi project, with a dual licensed under LLVM and MIT license. So, I’ve spent some time cleaning up the sources to make them conform with LLVM style and to conditionalize the sources in a way that should make it easier to port to other platforms. The sources are in a separate "Unwind" directory under "src" in libcxxabi. Background: Most architectures now use "zero cost" exceptions for C++. The zero cost means there are no extra instructions executed if no exceptions are thrown. But if an exception is thrown, the runtime must consult side tables and figure out how to restore registers and "unwind" from the current stack frame to the catch clause. That ability to modify the stack frames and cause the thread to resume in a catch clause with all registers restored properly is the main purpose of the unwinder. This unwinder has two levels of API. The high level APIs are the _Unwind_* functions which the cxa_* exception functions in libcxxabi require. The low level APIs are the unw_* functions which are an interface defined by the the old HP libunwind project (which shares no code with this unwinder). git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@192136 91177308-0d34-0410-b5e6-96231b3b80d8
