--- Comment #9 from Quentin Colombet <qcolombet at apple.com> ---
I have disabled shrink-wrapping for functions that have the split-stack
attribute or the HiPE calling convention in revision 258221.

The targeting of both callbacks is not ready to handle a prologue block that is
not the entry block of the function. Fixing that is probably easy (we need to
insert the new blocks right in front of the prologue instead of the begin of
the function and patch the predecessors of the prologue block to adjust the
jump to the new block) but I don’t have time to do it right now.
