Avoid duplicate definitions of xlat structures in files compiled in mpers mode. Each xlat file defines the corresponding xlat struct with either global or local visibility using the following rules: - if xlat struct declaration is available in defs.h, a global definition is provided in regular mode, and nothing is provided in mpers mode; - otherwise, if xlat file is included by a mpers source file, a global definition is provided in regular mode (unless no mpers mode is supported on this architecture, in that case, a local definition is provided instead), and a declaration is provided in mpers mode; - otherwise, a local definition is provided in regular mode, and an error message is printed in mpers mode. Fallback definitions of constants provided by xlat files remain available in all modes. * bootstrap: Invoke generate_mpers_am.sh before xlat/gen.sh. * defs.h (adjtimex_modes, adjtimex_status, sigev_value): Remove. * generate_mpers_am.sh: Generate mpers_xlat.h. * Makefile.am (EXTRA_DIST): Add mpers_xlat.h. * print_sigevent.c: Include "xlat/sigev_value.h" unconditionally. * print_timex.c: Include "xlat/adjtimex_modes.h" and "xlat/adjtimex_status.h" unconditionally. * xlat/gen.sh (cond_xlat): Move printing of fallback definitions ... (cond_def): ... here. (gen_header): Check also mpers_xlat.h for global declarations of xlat structures. Process input file twice, first time print directives only, second time print everything. Wrap struct xlat into #ifdef IN_MPERS ... #else ... #endif. * xlat/getrandom_flags.in: Cleanup.
