You are right, thanks. Test case fixed thus in mainline (to be 4.3).

Yes, the GCC docs suggest using --target_board:

I no longer have access to the x86 boxes I was using for testin

With pic, the load of the global's address is pulled outside the loop, so the
"base" is a register rather than the global. This causes ivopts to represent
index*step all in the index field rather than as two separate fields

I have not looked enough into this one but IIRC -fPIC changes the number of
registers available to allocate with which causes different IV selection so the
it might be the testcase is wrong for -fPIC.

Forgot to say this is with -fpic or -fPIC.
