A bad switch causes -- a fatal error exit and control does not return.

Last is equal to zero, if it has been -- determined that Switch_Chars is ill-formed or does not contain any -- switch that should be stored in an ALI file. Otherwise, the list of -- simple switches is Switches (Switches'First .. Last). -- -- Example: if Switch_Chars is equal to "-gnatAwue", then the list of -- simple switches will have 3 components: -gnatA, -gnatwu, -gnatwe. -- -- The String_Access components of Switches should not be deallocated: -- they are shallow copies of components in a table in the body. function Normalize_Compiler_Switches (Switch_Chars : String) return Argument_List; -- Similar to the previous procedure. The return value is the list of -- simple switches. It may be an empty array if it has been determined -- that Switch_Chars is ill-formed or does not contain any switch that -- should be stored in an ALI file.
