From 7144b5f275f380941bffca9509ecb97542c8e5ea Mon Sep 17 00:00:00 2001 From: Stephanos Ioannidis Date: Mon, 7 Jun 2021 15:13:19 +0900 Subject: newlib: Add libstdc++ nano-specific CXXFLAGS This commit adds a new config that can be used to specify the target CXXFLAGS specific to the libstdc++ newlib-nano variant. By default, this config is set to specify the `-fno-exceptions` option, which disables C++ exception handling support and greatly reduces the compiled binary size.
