8 // the --no-enum-size-warning option is passed to the linker. Whilst the
9 // enum-size attributes should only be emitted if there are values of
10 // enum type that can escape the compilation unit, gcc cannot currently
11 // detect this; if this facility is added then this linker option should
12 // not be needed. arm-*-linux* should be a good approximation to
13 // those platforms where the EABI supplement defines enum values to be
14 // 32 bits wide.
