Note that this includes Nick's fix from edf64cd235 which
landed upstream a bit differently as r13-1566-g9ed57796235abc in GCC.
This pulls in libbacktrace as of r14-9404-gc775a030af9cad in GCC trunk.
Note that I have dropped a top-level Darwin change from r14-4825-g6a6d3817afa02b
which would've required an autoreconf, as it should be handled separately.

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.
