Summary: sparc64: DWARF unwinder required for GCC 4.2.1
retirement
Product: Base System
Version: CURRENT
Hardware: sparc64
OS: Any
Status: New
Severity: Affects Only Me

GCC 4.2.1's retirement is expected before FreeBSD 13.0. This will also remove
GCC's libgcc including the DWARF unwinder.
LLVM's libunwind provides the replacement for most architectures but does not
currently support sparc64.
