Hi,
this is a regression introduced on the SPARC by the somewhat controversial

registers optimization to a small function so a register window is now used.
The combiner change might be an overall win, but my understan
There's a long-standing issue with LIM which isn't very good at
recognizing same memory references esp. when they are in MEM vs.
traditional form. The following rectifies this for the class
of refs we can compute get_addr_base_and_unit_offset on (that
makes it easy to create a canonical ref).

Attached patch inlines calls to asinh{,f,l}, acosh{,f,l} and
atanh{,f,l} using x87 XFmode arithmetic. The expanders are modelled
