CLEAR_INSN_CACHE

[Kilbane, Stephen]

Hi,

I'm trying to add support to 4.3 for cache flushing when setting up a 
trampoline.
Reading around, it looks like I should be defining CLEAR_INSN_CACHE:

To clear the instruction cache when a trampoline is initialized, define the 
following macro.
   CLEAR_INSN_CACHE (beg, end)

but I can't see anywhere that this macro gets used during trampoline creation. 
I can see
that it provides an implementation for __clear_cache() in libgcc, but nothing 
that would
invoke that routine, either, short of an explicit call in the source file being 
compiled.

Am I missing something?

Thanks,

steve
