- # libunwind is only available for a certain subset of the
- # architectures (as visible in the list of architectures supported
- # with the glibc C library below).
- #
- # In addition to this, on some architectures libunwind requires the
- # *context() function from the C library, which are only available on
- # certain architectures in uClibc, and not available at all on
- # musl. But on some other architectures, libunwind works without using
- # the *context() functions, which allows it to be built with musl.
