Then I'll mark it non-inlined in an ARM copy; but I expect this to
cause problems on many other targets. It only materializes on very
recent versions of GCC, because previously we used -fno-unit-at-a-time
which suppressed the "inline static functions called once"
optimization; if GCC is new enough we use -fno-toplevel-reorder
instead.
Sedding GCC's assembly output has historically worked "well enough" for
simple calls to known static functions, but it's not surprising that
call_gmon_start requires a constant pool. I expect to see similar
problems at least for SH.
Anyway, you want an ARM-only fix, you'll get one :-) I'll take care of
it.
