Reload generating memory ref in memory ref

[Michael Eager]

Hi --

I'm running into a situation where reload is replacing
a pseudo-register in an insn with a memory reference.
The problem is that this is happening in a memory ref.

The initial pattern is something like

(set (reg/v:SI 1) (mem/s:SI (plus:SI
        (reg/f:SI 30)
        (const_int 4)) ))

After reload, this becomes

(set (reg/v:SI 1) (mem/s:SI (plus:SI
        (mem/f/c:SI (plus:SI (reg/f:SI 19) (const_int -2))
        (const_int 4))

The reg-equiv for pseudo-reg 30 is the mem ref in the middle.

Any idea about why this might be happening, or, better,
how to get reload to generate a load from reg-equiv to a reg
rather than replace the pseudo-reg with the reg-equiv?
