So the following is enough to fix the missed ldp due to alias analysis:
diff --git a/gcc/pair-fusion.cc b/gcc/pair-fusion.cc
index 31d2c21c88f..ab49d955ccf 100644

--- Comment #2 from Alex Coplan ---
Here is some analysis on why we miss some of these opportunities in ldp_fusion.
So initially in 267r.vregs we have some very clean RTL:
6: r101:DI=sfp:DI-0x40
7: x0:DI=r101:DI
8: call [`g']
