38 /**
39  **  This template file is used while building the GNAT runtime library to
40  **  generate package System.OS_Constants (s-oscons.ads).
41  **
42  **  The generation process is:
43  **  1. the platform-independent extraction tool xoscons is built with the
44  **     base native compiler
45  **  2. this template is processed by the cross C compiler to produce
46  **     a list of constant values
47  **  3. the comments in this template and the list of values are processed
48  **     by xoscons to generate s-oscons.ads.
49  **
50  **  Any comment occurring in this file whose start and end markers are on
51  **  a line by themselves (see above) is copied verbatim to s-oscons.ads.
52  **  All other comments are ignored. Note that the build process first passes
53  **  this file through the C preprocessor, so comments that occur in a section
54  **  that is conditioned by a #if directive will be copied to the output only
55  **  when it applies.
56  **
57  **  Two methods are supported to generate the list of constant values,
58  **  s-oscons-tmpl.s.
59  **
60  **  The default one assumes that the template can be compiled by the newly-
61  **  built cross compiler. It uses markup produced in the (pseudo-)assembly
62  **  listing:
63  **
64  **     xgcc -DTARGET=\"$target\" -C -E s-oscons-tmplt.c > s-oscons-tmplt.i
65  **     xgcc -S s-oscons-tmplt.i
66  **     xoscons
67  **
68  **  Alternatively, if s-oscons-tmplt.c must be compiled with a proprietary
69  **  compiler (e.g. the native DEC CC on OpenVMS), the NATIVE macro should
70  **  be defined, and the resulting program executed:
71  **
72  **  $ CC/DEFINE=("TARGET=""OpenVMS""",NATIVE)
73  **      /PREPROCESS_ONLY /COMMENTS=AS_IS s-oscons-tmplt
74  **  $ CC/DEFINE=("TARGET=""OpenVMS""",NATIVE) s-oscons-tmplt
75  **  $ LINK s-oscons-tmplt
76  **  $ DEFINE/USER SYS$OUTPUT s-oscons-tmplt.s
77  **  $ RUN s-oscons-tmplt
78  **  $ RUN xoscons
