------- Comment #11 from jakub at gcc dot gnu dot org 2008-05-02 09:34 -------
The unexpected address is created by simplify_plus_minus on
(plus:DI (reg:DI 2 2)
(const:DI (minus:DI (symbol_ref/u:DI ("*.LC1") [flags 0x2])
(symbol_ref:DI ("*.LCTOC1")))))
and
(const_int 8 [0x8])
where the .LCTOC1 and +8 pair is simplified together. Unfortunately, if we
refuse it in rs6000_legitimate_address, fwprop doesn't try harder
(LEGITIMIZE_ADDRESS/memory_address isn't called) and nothing afterwards
propagates it either, so we end up with:
la 9,[EMAIL PROTECTED](2)
ld 0,8(9)
instead of
ld 0,[EMAIL PROTECTED](2)
So I'm afraid we want to accept it.
