re PR target/36780 (Wrong reload generated for subreg address on SH)
PR target/36780
PR target/36827
* reload.c (find_reloads_subreg_address): Only reload address if
reloaded == 0, not for reloaded != 1.
Revert:
2008-07-16 Joseph Myers <joseph@codesourcery.com>
* config/m32c/m32c.c (BIG_FB_ADJ): Move definition earlier.
(m32c_legitimate_address_p): Handle "++rii" addresses created by
m32c_legitimize_reload_address.
2008-07-15 Kaz Kojima <kkojima@gcc.gnu.org>
* config/sh/sh.h (GO_IF_LEGITIMATE_ADDRESS): Allow
(plus (plus (reg) (const_int)) (const_int)) when reload_in_progress.
