Caveats

    +
  • libstdc++ uses constructors inside the library to initialize std::cout/std::cin, etc. + instead of having it done in each source which uses iostream header. + This requires you to make sure the dynamic loader to load the new libstdc++v3 library + (examples of how to do this is to use -Wl,-rpath,... while linking or LD_LIBRARY_PATH + while running the program).
  • OpenMP offloading to Intel MIC has been removed.
  • The support for the cr16-elf, tilegx*-linux, tilepro*-linux, hppa[12]*-*-hpux10*, hppa[12]*-*-hpux11* -- 2.31.1
