For switches that are -- recognized, Success is set to True. A switch that is not recognized and -- consists of one small letter causes a fatal error exit and control does -- not return. For all other not recognized switches, Success is set to -- False, so that the switch may be passed to the compiler. -- -- Project_Node_Tree is used to store tree-specific parameters like the -- project path. procedure Normalize_Compiler_Switches (Switch_Chars : String; Switches : in out Argument_List_Access; Last : out Natural); -- Takes a compiler switch which potentially is equivalent to more -- that one simple switches and returns the equivalent list of simple -- switches that are stored in an ALI file. Switches will be extended -- if initially null or too short. Last indicates the index in Switches -- of the last simple switch. 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. The String_Access components of the -- returned value should not be deallocated. end Switch.M;
