Your comment is somewhat ambiguous (all targets use a direct jump, ARM just
has tighter restrictions on when that is possible). I suggest:
/* The prologue must be reachable with a direct jump. ARM has a limited
branch range (possibly also PPC and SPARC?) so place it in a section
close to code segment. */
Ok with that change.
