It'll also conditionally generate the defines, so that if we don't have
those when building a new tool tarball in an older systems, we get
those, and we need them sometimes in the actual scnprintf routine, such
as when checking if a flags means we have an extra arg, like with
MREMAP_FIXED.
$ tools/perf/trace/beauty/mremap_flags.sh
static const char *mremap_flags[] = {
[ilog2(1) + 1] = "MAYMOVE",
#ifndef MREMAP_MAYMOVE
#define MREMAP_MAYMOVE 1
#endif
[ilog2(2) + 1] = "FIXED",
#ifndef MREMAP_FIXED
#define MREMAP_FIXED 2
#endif
[ilog2(4) + 1] = "DONTUNMAP",
#ifndef MREMAP_DONTUNMAP
#define MREMAP_DONTUNMAP 4
#endif
};
