------- Comment #4 from rearnsha at gcc dot gnu dot org 2008-12-10 15:38 -------
Some notes on the failure path:
combine generates the pattern
(insn 1466 1464 1467 192 regeximp.h:320 (set (reg:SI 1002)
(sign_extend:SI (mem/s/j:QI (plus:SI (reg:SI 1000)
(mult:SI (reg/v:SI 246 [ opValue.1977 ])
(const_int 32 [0x20])))
[note the address in the mem is not in canonical form]
Register allocation realises that a scaled register is not permitted for a
sign_extend(mem()) operation and splits the entire sub-expression into a
separate insn. However, because that insn is not in canonical form, it then
fails to recognize the result.
