- Description:
- The primary goal of this project is to define a portable and efficient C
programming interface (API) to determine the call-chain of a program. The API
additionally provides the means to manipulate the preserved (callee-saved) state
of each call-frame and to resume execution at any point in the call-chain
(non-local goto). The API supports both local (same-process) and remote
(across-process) operation. As such, the API is useful in a number of
applications. Some examples include:
- exception handling
The libunwind API makes it trivial to implement the stack-manipulation aspects
of exception handling.
- debuggers
The libunwind API makes it trivial for debuggers to generate the call-chain
(backtrace) of the threads in a running program.
- introspection
It is often useful for a running thread to determine its call-chain. For
example, this is useful to display error messages (to show how the error came
about) and for performance monitoring/analysis.
- efficient setjmp()
With libunwind, it is possible to implement an extremely efficient version of
setjmp(). Effectively, the only context that needs to be saved consists of the
stack-pointer(s).

devel/libunwind: use base system unwind.h
- Add --disable-cxx-exceptions so libunwind does not implement the
_Unwind_* API and does not use its internal unwind.h. The base
system libgcc_s provides this API. This was already the upstream
default for most architectures.
- Add --disable-unwind-header to prevent installation of unwind.h.
Instead, install an unwind.h that forwards to the base system
unwind.h, but not on FreeBSD 14 where all implementations of
unwind.h (base, lang/gcc*, and devel/llvm*) are compatible.
