This patch adds support for building libsupc++ (the C++ runtime support library from GCC's libstdc++-v3). libsupc++ provides core C++ runtime support including: - Exception handling (eh_*.cc) - RTTI (Run-Time Type Information) - Memory allocation operators (new/delete) - Type info support The implementation includes: - libsupc++.defs for libsupc++ build integration - support make and cmake build - Use gthr.h, gthr-posix.h and unwind-pe.h from libgcc - LIBSTDCXX_VERSION config option with default 14.2.0 Signed-off-by: cuiziwei <cuiziwei@xiaomi.com>		2026-01-24 17:33:19 +08:00
