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
