The libbacktrace library

Initially written by Ian Lance Taylor <iant@golang.org>

The libbacktrace library may be linked into a program or library and

used to produce symbolic backtraces.

Sample uses would be to print a detailed backtrace when an error

occurs or to gather detailed profiling information.

In general the functions provided by this library are async-signal-safe,

meaning that they may be safely called from a signal handler.

The libbacktrace library is provided under a BSD license.

See the source files for the exact license text.

The public functions are declared and documented in the header file

backtrace.h, which should be #include'd by a user of the library.

Building libbacktrace will generate a file backtrace-supported.h,

which a user of the library may use to determine whether backtraces

will work.

See the source file backtrace-supported.h.in for the macros that it

defines.

As of October 2020, libbacktrace supports ELF, PE/COFF, Mach-O, and

XCOFF executables with DWARF debugging information.

In other words, it supports GNU/Linux, *BSD, macOS, Windows, and AIX.

The library is written to make it straightforward to add support for

other object file and debugging formats.

The library relies on the C++ unwind API defined at

https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html

This API is provided by GCC and clang.
