Yes, I thought you'd like that :^). It should help IA-64.
The PRE/POST_MODIFY fix is following the current documentation for
*_MODIFY in rtl.def: the first operand of the *_MODIFY is a REG and needs
to match the REG of the computation in the second operand. Walking
through a *_MODIFY means following the first operand.
