29 -- This package scans make switches. Note that the body of Usage must be
30 -- coordinated with the switches that are recognized by this package.
31 -- The Usage package also acts as the official documentation for the
32 -- switches that are recognized. In addition, package Debug documents
33 -- the otherwise undocumented debug switches that are also recognized.

39 procedure Scan_Make_Switches (Switch_Chars : String);
40 -- Procedures to scan out binder switches stored in the given string.
41 -- The first character is known to be a valid switch character, and there
42 -- are no blanks or other switch terminator characters in the string, so
43 -- the entire string should consist of valid switch characters, except that
44 -- an optional terminating NUL character is allowed. A bad switch causes
45 -- a fatal error exit and control does not return. The call also sets
46 -- Usage_Requested to True if a ? switch is encountered.
48 procedure Normalize_Compiler_Switches
49 (Switch_Chars : String;
50 Switches : in out Argument_List_Access;
52 -- Takes a compiler switch which potentially is equivalent to more
53 -- that one simple switches and returns the equivalent list of simple
54 -- switches that are stored in an ALI file. Switches will be extended
55 -- if initially null or too short. Last indicates the index in Switches
56 -- of the last simple switch. Last is equal to zero, if it has been
57 -- determined that Switch_Chars is ill-formed or does not contain any
58 -- switch that should be stored in an ALI file. Otherwise, the list of
59 -- simple switches is Switches (Switches'First .. Last).
61 -- Example: if Switch_Chars is equal to "-gnatAwue", then the list of
62 -- simple switches will have 3 components: -gnatA, -gnatwu, -gnatwe.
64 -- The String_Access components of Switches should not be deallocated:
65 -- they are shallow copies of components in a table in the body.
67 function Normalize_Compiler_Switches
68 (Switch_Chars : String)
70 -- Similar to the previous procedure. The return value is the list of
71 -- simple switches. It may be an empty array if it has been determined
72 -- that Switch_Chars is ill-formed or does not contain any switch that
73 -- should be stored in an ALI file. The String_Access components of the
74 -- returned value should not be deallocated.
